[0031] The following is a further detailed description of the present invention in conjunction with the attached Figure 4 - attached Figure 5 drawings.

[0032] The embodiment of the present invention discloses an anti-accumulation structure for the drum of a material loader. Referring to Figure 4 , the anti-accumulation structure for the drum of the material loader includes a baffle 2, and the baffle 2 is used to block the groove between two hopper middle plates 111. In other embodiments, multiple baffles 2 may be arranged along the length direction of the drum 10 and welded between the upper and lower two bucket teeth 112 or bolt-connected. In this embodiment, a support frame 3 for facilitating the disassembly and replacement of the baffle 2 is designed, and the support frame 3 is arranged in the groove.

[0033] Referring to Figure 4, the support frame 3 includes a bottom plate 30 that is bow-shaped and welded to fit between the two hopper middle plates 111. Two fixed cylinders 31 are welded in the middle of the bottom plate 30 along the length direction of the roller 10. The axial direction of the fixed cylinder 31 is perpendicular to the axial direction of the roller 10. On the side of the baffle 2 facing away from the groove, a counterbore 20 is correspondingly provided. A fixing screw 32 for threaded connection with the fixed cylinder 31 is arranged in the counterbore 20.

[0034] Referring to Figure 4 and Figure 5 , in order to reduce the wear of the nut of the fixing screw 32 by the ore material, so as to facilitate the later staff to screw and loosen the fixing screw 32 to replace the baffle 2. A retaining cap 33 is detachably installed on the nut of the fixing screw 32. The retaining cap 33 includes a back plate 330 and six clamping plates 331 welded to the side of the back plate 330 close to the fixing screw 32. A gap is provided between two adjacent clamping plates 331. A clamping groove 3310 is provided on the inner side of the clamping plate 331. Correspondingly, a convex rib 320 is welded on the outer wall of the nut of the fixing screw 32. The length direction of the convex rib 320 is perpendicular to the axial direction of the fixed cylinder 31. The convex rib 320 and the clamping plate 331 are clamped and fixed through the clamping groove 3310.

[0035] The implementation principle of the anti-accumulation structure for the roller of the material taking machine in the embodiment of the present invention is as follows: Place the baffle 2 at the position corresponding to the fixed cylinder 31, then fix it with the fixing screw 32, and finally buckle the retaining cap 33 on the nut of the fixing screw 32. When the material taking machine is working, since the baffle 2 blocks the ore material from adhering to the groove, the problem that the accumulated material is thrown to the rear of the traveling direction is solved, which does not affect the return travel, and there is no need for the staff to clean the accumulated material, improving the work efficiency and saving the labor cost. When the baffle 2 is worn to a certain extent and needs to be replaced, first remove the retaining cap 33, and then screw off the fixing screw 32, which is very convenient in operation.
