Description
TECHNICAL FIELD

[0002] In the field of mining and construction, a mine bulldozer is an indispensable important equipment, and its main function is to push flat, transport and other operations on soil piles, ore piles and the like, so as to arrange the site, open up roads and the like, and ensure the smooth progress of mining production.
[0003] With the continuous expansion of mining scale and the increasing requirements of operation, the traditional mine bulldozer gradually exposes many problems in actual use. On the one hand, during the bulldozing operation, it is difficult for the operator to accurately control the distance between the bulldozing blade and the soil pile. Due to the lack of effective distance measuring means, it can only be operated by experience, which leads to the fact that the bulldozing blade sometimes excessively penetrates into the soil pile, causing excessive load of the equipment, increased energy consumption, and even possible damage to the equipment; and sometimes the distance between the bulldozing blade and the soil pile is too large, which cannot effectively push the soil pile flat, affecting the operation efficiency and quality.
[0004] On the other hand, when facing a relatively solid soil pile or a soil pile containing hard stone blocks, the traditional mine bulldozer directly uses the bulldozing blade for pushing flat operation, which will encounter great difficulties. Solid soil and hard stone blocks will increase the pushing resistance of the bulldozing blade, which not only easily leads to the aggravation of the wear of the bulldozing blade and the shortening of the service life, but also may cause the equipment to be stuck, stagnant and the like during operation, seriously affecting the operation progress.
