Digging machine accessories crushing tongs are now widely used in the demolition industry. It is widely used in the demolition of buildings, beams and columns of factory buildings, and residential buildings, steel bar recycling, and concrete crushing. The working efficiency of the crushing tongs is two to three times that of the breaking hammer, and it can complete a series of operations well. It requires the connection and intelligence of the quality crushing tongs. So what are its advantages? Let's take a look. 1. Crushing tongs can greatly reduce labor input, high efficiency, reduce costs, and reduce safety risks. It can make up for the deficiencies of other machines in certain aspects, and can reduce construction noise and vibration during demolition engineering events. Demolition or stripping work with certain requirements or high standards can ensure high accuracy;  2. The installation principle of the crusher is roughly the same as that of the hydraulic breaker. It is necessary to connect the pin hole of the hydraulic crusher to the pin hole of the front end of the excavator, and then connect the pipeline on the excavator and the hydraulic crusher. Soon After the installation is completed, the crushing operation can be carried out;  3. The design of the oil circuit of the pulverizer should not only improve the working efficiency of the cylinder, but also facilitate the disassembly and maintenance. The oil circuit of the pulverizer can be used in common with the breaker, which can realize multiple functions of an excavator; Secondly, the oil tank of the crushing tongs and other key links need to be equipped with protective devices to prevent the reinforced concrete from splashing on the oil tank or damaging the oil tank during work and use;  4. The raw materials of the crushing tongs have been thoroughly studied: the use of high-hardness and light-weight steel, high strength and wear resistance; processing link: we have summarized experience through the research of most buildings and construction operations, if the jaw teeth of the crushing tongs are made into shapes In this way, the building can be quickly crushed, and the important parts need to be strengthened and wear-resistant treatment.

As the power system of construction machinery, diesel engines provide the power required to operate machinery. Obstacles affect normal production. Therefore, observing the color of exhaust gas is very important for diagnosing diesel engine faults. The normal color of diesel fuel after complete combustion is usually light gray or dark gray. Diesel in operation may cause abnormal conditions such as black smoke, white smoke and blue smoke. This is the condition for determining the failure of the diesel engine. Diesel is a complex hydrocarbon. The unburned diesel fuel injected into the combustion chamber is decomposed at a high temperature. When discharged, it is discharged together with the exhaust gas and becomes black smoke. Black smoke is a sign of incomplete combustion of fuel in the combustion chamber. The wear of the piston ring and cylinder liner will result in insufficient compression pressure, which will change the normal mixture ratio at the end of the cylinder compression stroke, thereby burning fuel and carbon under oxygen-free conditions. The fuel injector does not atomize or drip, so the fuel cannot be completely mixed with the air in the cylinder. (1) Because the advance angle of the fuel is too large, the fuel is quickly injected into the combustion chamber. The low pressure and high temperature in the cylinder cannot ignite the fuel. When the piston moves upward, the cylinder reaches a certain pressure and temperature, and the combustible mixture burns. (2) The fuel supply advance angle is too small, and the cylinder fuel is too slow. Before forming a combustible mixture, some fuel must be separated or discharged. The fuel discharged with the exhaust gas decomposes at high temperature to form black smoke. As more oil enters the cylinder, more gas cannot be completely burned, thereby reducing fuel oil. In addition, heavy workload, poor fuel quality and low working temperature will exhaust all exhaust gas. The lubricating oil enters the cylinder, is heated and evaporates into blue oil and gas. This is the introduction to the black smoke of the micro-excavator engine, I hope it will be helpful to you.

Does the dual-purpose excavator still need maintenance? I think many drivers will say that they have specialized excavator repairs and maintenance. If they are damaged, you can take a break. However, it must be pointed out that the excavator can only avoid frequent failures in the wheel-track dual-purpose excavator. Daily maintenance of excavators In order to prevent the wheel and track dual-purpose excavator from malfunctioning, extra care must be taken in the daily maintenance of the excavator. The daily maintenance of the excavator includes: Check, clean or replace the air filter. Clean the inside of the cooling system. Check and tighten the track shoe bolts. Check and adjust the tension behind the track. Check the air inlet heater and replace the teeth. Adjust the bucket clearance. Check the level of cleaning fluid on the front window. Check and adjust the air conditioner, and clean the floor inside the cab. Replace the circuit breaker filter (optional). Note: When cleaning the inside of the cooling system, after the engine is completely cooled down, before releasing the water, slowly loosen the water inlet cap to release the internal pressure of the water tank. Do not clean the engine during operation. Rotating the fan at high speed is dangerous. When cleaning or replacing the coolant, park the machine on a flat surface. At the same time, you need to check the coolant level (add water) before starting the engine. Check the engine oil level, add oil, check the fuel oil level (add oil), check the hydraulic oil level (add hydraulic oil), check whether the air filter is blocked, check the wire, check whether the horn is normal, check the bucket lubrication, check Whether there is water and sediment in the water separation container. Excavators encounter many failures in their daily work. Daily maintenance of excavators is very important to reduce the occurrence of failures. Only the double guarantee of maintenance and maintenance can improve the operation of the excavator. Therefore, it is necessary to carry out routine maintenance on the dual-purpose excavator. If you encounter minor problems every time, please consult a professional maintenance supervisor. There are many worthless losses.

Small excavators will be more competitive with high cost performance and economic use. At the same time, economically developed cities have higher labor costs, replacing labor with machinery, improving labor efficiency, and adding small excavators to be more suitable for use in places with limited space, which also indicates that the era of rapid development of small excavators is coming. The market prospect is attractive and the potential is huge. Small excavators are low in price, light in weight, flexible in operation, and convenient in maintenance and repair. They are very suitable for urban construction, various pipeline excavation, and public facility construction. The compact design of the small excavator enables it to work in environments where large excavators cannot complete the construction. Secondly, small excavators have versatility and distinctive operating characteristics. In addition, cumbersome procedures such as consignment are also omitted in the work space. Small excavators can be said to be the mainstream of the excavation machinery industry now. Many owners of large vehicles are deeply impressed. It is difficult to maintain a car, difficult to pay back, and no money is seen throughout the year, but small excavators are not. Most of them are small projects. Generally speaking, they don’t hold down their money, they are strong after their work, with small investment and a lot of money. They can be said to be a good helper for rural people to get rich. Today's analysis of small excavators is here. There are also articles about small excavators to share before, and you can also read them. There will be more sharing and summary of knowledge about excavators in the future. Welcome everyone to provide valuable comments. Finally, I wish everyone a prosperous business and happy every day.

Small excavators are indispensable in mining, urban construction, and road construction. When it comes to building roads, everyone thinks of small excavators. Whether you are building highways, tunnels, or mining construction sites, you can see small excavators. Today, the editor will talk to you about the skills of small excavators to build roads on the construction site. On the construction site, road repairing is a very important job, and it also requires certain skills, especially for roads with slopes. If the slope is too large, the car will not be able to get up. If the slope is too small, the slope will be too high. long. How can we build a road that is neither very steep nor too long? 1. First observe the distance between the top of the slope and the low end of the slope Before starting to repair the slope, first observe the span and distance of the upper and lower ends of the slope to be repaired to determine the size of the slope to be repaired. If an up and down road is opened directly from a step, the length and size of the slope must be determined by the height of the step. The higher the height of the step, the longer the slope will be (of course, it must be based on the actual environment of the site. Determine the length of the slope). 2. The prototype of using a small excavator to repair the way out After deciding on the slope of the road to be repaired, start digging with a small excavator. Start by layering from the upper end of the slope and gather it down, so that the soil at the upper end of the slope can be gathered to the bottom to elevate the road below and reduce the slope of the entire road. When you gather from the top to almost half of the slope, use a bucket to flatten the soil gathered below, and the general outline of the entire road surface has been formed. 3. Leveling of the ramp  When the slope is roughly formed, we must level the road surface of the ramp. Still from the upper end of the slope, pat down the raised part with a bucket, and line up the recessed part (of course, experienced operators can usually form it at once). If there is only a small amount of loose soil and rock on the ground, it needs to be processed and leveled. , We can use a small excavator to rotate the soil and rock. It should be noted that the rotating force will be relatively small. When it encounters hard soil or a lot of soil, it will not be “swept”. At this time, there will be more The combination of compound movements sweeps away the soil. When the slewing force is insufficient and the bucket is "stuck", we can use the forearm to retract back and forth and the small opening and closing of the bucket to reduce the resistance of the bucket, thereby "sweeping" the hard soil away. In this way, when the road is relatively flat, the crawler of a small excavator is used to walk back and forth on the entire road for a few laps, and the road is compacted with the crawler, so that a ramp is OK. Repairing roads on construction sites is a common operation for small excavators, but to repair the roads, it is necessary to rely on skilled operation skills and keen observation. Working conditions are ever-changing, and only when we have mastered more operating skills can we cope with various complex working conditions.
