Why do small excavators stand out in agricultural applications?

Small excavators have been gradually used in agricultural work around We summarize the unique working characteristics of agricultural small excavators.
Due to the design of the tail radius, when the agricultural mini excavator works in a limited working environment, the mini excavator operator does not need to consider whether there are obstacles that hinder the rotation of the mini excavator, so that the operator can focus more on the bucket. This It can also prevent the damage of the mini excavator around construction and construction sites. The main feature of the agricultural mini excavator in narrow areas is its special boom design.

The boom of the agricultural mini excavator is hinged on the body and can swing in a wide range. This design allows the mini excavator to avoid obstacles when going around obstacles without the need to move the body frequently. At the same time, this It makes it easy for the mini excavator to carry out excavation work on or beside the wall. The rubber track of the agricultural mini excavator helps to reduce the damage to the landscape and roads in narrow construction areas during the excavation process.

The track of the crawler-type walking characteristic of the agricultural small excavator transfers the load to the ground through the rollers and the walking frame connected with the slewing ring. The track surrounds the driving wheel and the guide wheel. In order to reduce the deflection of the upper branch, the track consists of 1-2 A load roller is supported to carry the load. The drive of the traveling device is driven by a hydraulic motor, and the drive wheel is driven by the reduction box to drive the entire operating device. When the track is elongated due to wear, the tensioning device can adjust the tension.

Among them, the guide wheel, roller, driving wheel and sprocket are called "four wheels and one belt", which is an important part of the crawler walking device, which is directly related to the working performance. The walking performance of the small excavator. The weight of this part is very large. It accounts for about 1/4 of the whole machine, and the manufacturing cost is also very high, accounting for about 1/4 of the whole machine.

Therefore, it is of great significance to rationally design the "Sifa Belt". In the past, these parts had many specifications in China. According to incomplete statistics, there are 34 types of structures and about 93 types of specifications, which affect the improvement of processing quality and the supply of spare parts. Components Poor interchangeability leads to poor mechanical integrity. In order to overcome the above deficiencies and improve quality, relevant departments have unified the "four wheels and one belt" drawings of small excavators, bulldozers, and loaders, and gradually standardize, promote, and serialize, improve product quality, and speed up Product quality. The development of construction machinery has created conditions.

The unique and distinctive features of agricultural mini excavators make them stand out in the industry and are highly praised by people.
