The bottom plate of the utility model is a semi-bottomed structure composed of a left bottom plate and a right bottom plate. The left bottom plate is welded on the bottom of the shovel side, and the right bottom plate is welded on the bottom of the baffle side.

The cable trough of the utility model is a trapezoidal structure trough.

Each cable hook of the utility model is composed of a telescopic rod and a plurality of hooks. The lower end of the fixed segment rod of the rod and some telescopic segment rods, the upper end of the fixed segment rod of the telescopic rod is welded on the upper end position of the outer side wall of the cable groove.

The hardening strip of the utility model is a plasma cladding coating.

The thickness of the plasma cladding coating described in the utility model is 0.05-8mm, and the shape of the plasma cladding coating is a straight line or a curved line.

The advantages of this utility model are: 1) The shovel plate groove side, the baffle plate groove side and the middle plate are integral parts welded together, and the middle plate is a box-shaped structure composed of an upper middle plate and a lower middle plate, so the The overall strength of the middle groove is high, and it is not easy to break and deform; 2) There are set Hardened belt, so the middle groove is wear-resistant, has a long service life, and has high production efficiency and small deformation; 3) The bottom plate is a semi-bottomed structure composed of the left bottom plate and the right bottom plate, so the middle groove is also used when repairing the scraper chain. It is very convenient, and it is not easy to pull back the coal; 4) The cable groove is a trapezoidal structure groove, which not only saves materials and manufacturing costs, but also is very convenient when disassembling cables from the cable groove; 5) Welded on the upper end of the outer wall of the cable groove Each piece of cable hook is composed of a telescopic rod and several hooks, and they can adjust the height from the ground through the telescopic rod according to the height of the cable, which is convenient for management and saves space.
