Mulching soil removing device for cave of phosphorite mine

Abstract

The invention discloses a mulching soil removing device for a cave of phosphorite mine. The mulching soil removing device comprises a connecting plate, wherein two sides of the upper part of the connecting plate are provided with ear plates with shaft holes; a trapezoidal reinforcing plate is welded between the two ear plates; two or more than two arc-shaped toothed bars with bucket teeth are welded at the middle position of the bottom of the connecting plate; a strengthening plate is welded among the square peripheral edge of the connecting plate and the outer walls of the toothed bars; a distance between the upper end parts of two adjacent toothed bars is 40cm to 60cm; the inner sides of the arc-shaped curved surfaces of the toothed bars are provided with alloy protecting jackets through pin rolls; the upper parts of the bucket teeth are provided with tooth sleeves through pin rolls; the inner side walls of the lower parts of the bucket teeth are provided with two arc-shaped flow guiding grooves; the flow guiding grooves extend along a direction in which the bottoms of the bucket teeth point to the bottoms of the tooth sleeves. The depths of the flow guiding grooves are increased progressively along the extension directions of the flow guiding grooves, so that, along with the embedment of the bucket teeth, a space for releasing extrusion-force action among the inner side walls of the bucket teeth and a material matrix is increased step by step; the undercutting efficiency of the bucket teeth is further improved.

Description

technical field [0001] The invention relates to an excavator, in particular to a soil removal device for phosphate rock mine caves. Background technique [0002] bulldozer It is an engineering vehicle with a large metal bulldozing knife installed in the front. When in use, put down the bulldozing knife to shovel forward and push mud, sand and stones, etc. The position and angle of the bulldozing knife can be adjusted. The bulldozer can complete excavation, soil transportation and unloading alone, and has the advantages of flexible operation, convenient rotation, and working face Small, fast driving and other characteristics. It is mainly applicable from one to Three types of soil Shallow excavation and short transportation, such as site clearing or leveling, where the excavation depth is not large Foundation pit and backfill, build small height subgrade Wait. track The track-type tractor (also called crawler dozer) was successfully developed by American Benjamin...

AI Technical Summary

Problems solved by technology

[0003] At present, when construction machinery such as bulldozers and graders use rippers, due to the harsh and complicated working environment, the working load and impact load are relatively large, the racks and tooth tips of the rippers are subject to a large force, which is easy to cause damage and reduces the gear. The service life of the rod and tooth tip increases the cost and affects the benefit of the enterprise
