Excavators work on different occasions and will choose different tooling accessories, common accessories such as buckets, breakers, rippers, hydraulic clamps and so on. Only by selecting the right accessories, can we obtain high-speed and effective working ability for various working conditions. but do you know? For various working conditions, there are more than ten types of excavator buckets, each of which has its own advantages. The following are the most common excavator buckets. Owning them will surely make you The equipment is even more powerful!
1. Standard bucket
The standard bucket is a standard bucket that is relatively common in small and medium-sized excavators. It uses a standard plate thickness, and there is no obvious reinforcement process on the bucket body. The characteristics are: the bucket has a larger capacity, a larger mouth area, and a larger stacking surface, so it has a higher filling factor, high work efficiency, and low production cost. It is suitable for lighter working environments such as the excavation of general clay and the loading of sand, soil, and gravel. It is also known as earthmoving bucket. The disadvantages are: due to the small thickness of the plate, the lack of reinforcement technology, such as reinforcement plates and wear plates, the life is short.
2. Strengthen the bucket
The reinforced bucket is a bucket that uses high-strength wear-resistant steel materials to reinforce the high-stress and easily worn parts on the original basis of the standard bucket. It not only inherits all the advantages of the standard bucket, but also greatly improves the strength and resistance. Abrasiveness and long service life. It is suitable for heavy-duty operations such as digging hard soil, softer rocks, gravel and gravel loading.
3. Rock bucket
The rock digging bucket adopts thick plates as a whole, adding reinforcement plates at the bottom, adding side guards, installing protective plates, high-strength bucket teeth, suitable for loading rocks, sub-hard rocks, weathered rocks, hard rocks, blasting ore, etc. Heavy operating environment. It is widely used in harsh working conditions such as ore mining.
4. Mud bucket
The excavator mud bucket is also known as the dredging bucket. It has no teeth and has a large width. The bucket is very suitable for surface trimming of slopes with large capacity, and dredging of rivers and ditches.
5. Sieve fighting
It is suitable for the excavation of separated loose materials. Excavation and separation can be completed at one time. It is widely used in municipal, agriculture, forestry, water conservancy, and earthwork projects.
The bucket teeth depend on the working environment during the use process to determine the specific type of bucket teeth. Generally, flat-head bucket teeth are used for excavation, weathered sand, and coal. RC type bucket teeth are used for digging massive hard rocks, and TL type bucket teeth are generally used for digging massive coal seams. TL bucket teeth can increase the rate of coal lump production. In actual use, users often like general-purpose RC type bucket teeth. It is recommended not to use RC type bucket teeth under special circumstances. It is best to use flat-head bucket teeth, because RC type bucket teeth will increase like a "fist" after being worn out for a period of time. The digging resistance is reduced and power is wasted. The flat-mouth bucket teeth always maintain a sharp surface during the wear process, which reduces digging resistance and saves fuel.
02. Replace bucket teeth in time
When the tip part of the bucket tooth wears more severely, the force required by the excavator to cut in during the excavation operation will inevitably be greatly increased, resulting in greater fuel consumption and affecting work efficiency. Therefore, it is very necessary to replace the new bucket teeth in time when the bucket tooth wear is more serious.
03. Replace the tooth seat in time
The wear of the tooth seat is also very important to the service life of the bucket teeth of the excavator. It is recommended to replace the tooth seat after 10%-15% of the tooth seat is worn out, because there is a relatively large amount of wear between the tooth seat and the bucket teeth. The large gap changes the fit and stress point of the bucket tooth and the tooth seat, and the bucket tooth breaks due to the change of the force point.
04. Daily inspection and tightening
In the daily maintenance work of the excavator, take 2 minutes a day to check the bucket. The main inspection contents are: the degree of wear of the bucket body and whether there are cracks. If the degree of wear is severe, reinforcement should be considered. As for the bucket body with cracks, it should be repaired by welding in time to avoid increasing the length of the cracks due to delayed repairs and causing impossible maintenance. In addition, you must kick the bucket teeth with your feet to check whether the teeth are stable. If the teeth are loose, they should be tightened immediately.
05. Change position after wear
Practice has proved that during the use of excavator bucket teeth, the outermost tooth of the bucket wears 30% faster than the innermost tooth. It is recommended to reverse the position of the inner and outer teeth after a period of use.
06. Pay attention to driving method
The driving method of the excavator driver is also very important to improve the utilization of the bucket teeth. The excavator driver should try not to retract the bucket when lifting the boom. If the driver raises the boom while retracting the bucket, this operation will The bucket teeth are subjected to an upward traction, so that the bucket teeth are torn apart from the top, and the bucket teeth are torn. This operation requires special attention to the coordination of the action. Some excavator drivers often use too much force in the action of expanding the arm and sending the forearm, and quickly "knock" the bucket against the rock or force the bucket against the rock, which will break the bucket teeth, or It is easy to crack the bucket and damage the arms.
The excavator driver should pay attention to the excavation angle during operation. When the bucket teeth are digging down perpendicular to the working surface, or the camber angle is not more than 120 degrees, to avoid breaking the bucket teeth due to excessive inclination. Also be careful not to swing the digging arm left and right under the condition of large resistance, which will cause the bucket teeth and gear seat to be broken due to excessive force on the left and right, because the mechanical design principle of most models of bucket teeth does not consider the force on the left and right. design.
