Stone picking device and stone picking control method

Abstract

The invention belongs to the technical field of bulldozers and discloses a stone picking device and a stone picking control method. The stone picking device comprises a main body and a scraper knife.An angle adjusting oil cylinder, a lifting oil cylinder and a bracket are rotationally arranged between the main body and the scraper knife. The scraper knife comprises a crossbeam and a stone pickingrake. One end of the crossbeam is rotationally connected to the angle adjusting oil cylinder, the lifting oil cylinder and the bracket. The other end of the crossbeam is used for being detachably connected to the stone picking rake. The angle adjusting oil cylinder is used for adjusting the angle of the scraper knife. The lifting oil cylinder is used for adjusting the height of the scraper knife.The stone picking device further comprises an assistance mechanism. One end of the assistance mechanism is connected to the crossbeam. The other end of the assistance mechanism is detachably connected to the stone picking rake. The assistance mechanism is adjustable in length and is used for pushing and pulling the stone picking rake. The stone picking device can be selectively adjustable in length through the assistance mechanism, the assistance mechanism is used for installation and disassembly of the stone picking rake and the crossbeam and achieves an assistance effect, labor burden of operators is relieved, replacement time is shortened, maintenance cost is reduced, and thus production efficiency is improved effectively.

Description

Technical field [0001] The invention relates to the technical field of bulldozers, in particular to a stone picking device and a stone picking control method. Background technique [0002] The bulldozer is a kind of engineering vehicle. The front is equipped with a large metal blade. When in use, the blade is put down to shovel and push sand and stones forward. The bulldozer can independently complete excavation, soil removal, soil unloading and road opening. The cleaning or leveling work has the characteristics of flexible operation and convenient rotation. [0003] As the supply of land becomes more and more tense, the transformation of inferior land such as river beaches, Gobi and sandy land has become more urgent and common. The reconstruction of poor-quality land requires the sorting of stones from the land. At present, the commonly used stone sorters are generally formed by the reconstruction of bulldozers and skid steer loaders. However, the existing stone sorters can only ...

AI Technical Summary

Problems solved by technology

The improvement of poor-quality land needs to sort out the stones from the land. At present, the commonly used stone sorters are generally formed through the transformation of bulldozers and skid loaders. However, the existing stone sorters can only sort the stones on the ground surface, and cannot separate them. Sorting and discovering the rocks below the surface, unable to comprehensively and systematically sort out the rocks in the ground, the sorting quality is low

At the same time, with the prolongation of use time, the shovel is prone to wear and tear. The installation and disassembly of the existing shovel all need to be done manually. The weight of the shovel is large, the structure is irregular, and special tools are required for installation and disassembly, which makes the operation difficult. , and the safety of the workers cannot be guaranteed, the labor intensity of the operators is high, and the production efficiency is low
