Detailed Description

The utility model is described below with reference to the following figures and embodiments:

fig. 1-2 show a block diagram of a grid assembly of an automatic slag removal machine. The automatic slag removal mechanical grating device comprises a water inlet well 1, a mechanical grating machine 4, a slag collection box 8 and a deodorization device, wherein the lower end part of the mechanical grating machine 4 is placed in the water inlet well 1 between a water inlet 2 and a water outlet 3, the left side and the right side of the mechanical grating machine 4 are respectively provided with a first transmission chain 5, the ground below a top platform 10 is provided with the slag collection box 8, and a motor 11 on the top platform 10 drives the first transmission chain 5 through a speed reducer 11a and a second transmission chain 5 a; the first transmission chain 5 is provided with a deslagging device which comprises a deslagging rake 6 and a rake tooth sleeve, two ends of a cross rod 6c of the deslagging rake 6 are respectively and fixedly connected to the first transmission chain 5 at two sides of the mechanical grating machine 4, and the cross rod 6c is provided with a row of transverse rake teeth 6a and a row of longitudinal rake teeth 6b (as shown in figure 4).
