[0025] The feeding mechanism 4 includes a conveying cylinder 401, in which two baffles 407 are fixed, and a rotatable rotating rod 402 is transversely arranged in the two baffles 407, and a spiral blade 403 is fixed on the rotating rod 402. A driving bevel gear 405 is rotatably installed at the top and in the middle of the inner cavity of the conveying cylinder 401, and a driven bevel gear 404 is fixed at one end of the rotating rod 402. The driven bevel gear 404 is meshed on both sides of the driving bevel gear 405. A first motor 406 for driving the driving bevel gear 405 to rotate is fixedly installed on the conveying cylinder 401, and discharge pipes 408 are fixed at both ends of the end face of the conveying cylinder 401.

[0026] The device starts the first motor 406 to drive the active bevel gear 405 to rotate, and then the active bevel gear 405 engages the driven bevel gear 404, so that the rotating rod 402 rotates, and then the rotating rod 402 drives the spiral blade 403 to rotate to transport the material.

[0027] Among them, the unloading pipe of the feed box 3 is connected with the upper end of the conveying cylinder 401, and the two ends of the conveying cylinder 401 of the two feed boxes 3 are convenient for materials to fall to both sides of the baffle 407 respectively, so as to be transported.

[0028] At the same time, one end of the discharge pipe 408 is located in the guide pipe 6, which is convenient for the material in the conveying cylinder 401 to fall into the guide pipe 6. One end of the rotating rod 402 is rotatably connected to one side of the inner cavity of the conveying cylinder 401, increasing the stability of the rotating rod 402 when rotating.

[0029] See also Figure 1-6The weighing guide mechanism 5 in this embodiment includes a gear 501 and a side plate 507. The gear 501 is rotatably installed on the upper end of the grinder 1. Two side plates 507 are fixed on the grinder 1. A slide plate 503 that can slide left and right is provided on the side plate 507. A rack 502 meshing with the gear 501 is fixed on one side of the slide plate 503. A weighing plate 509 that can slide left and right is horizontally arranged in the guide tube 6. A cross bar 504 is fixed at one end of the slide plate 503. One side of the weighing plate 509 is fixed to one end of the cross bar 504.

[0030] A weight sensor 505 for weighing materials is fixed to the upper end of the weighing plate 509 , and a top plate 506 is fixed to the upper end of the weight sensor 505 .

[0031] The device allows materials to fall onto the top plate 506, and then the weight sensor 505 weighs the materials. When a certain weight is reached, the second motor 510 drives the weighing plate 509 to move toward the opening so that the materials fall into the crushing box.

[0032] Among them, an opening is provided on one side of the guide tube 6, and the weighing plate 509 is slidably connected to the opening to facilitate the left and right movement of the weighing plate 509.

[0034] The working principle of the above embodiment is:

[0035] When in use, the material is poured into the feed box 3, and then the first motor 406 is started to drive the active bevel gear 405 to rotate, and then the active bevel gear 405 engages the driven bevel gear 404, so that the rotating rod 402 rotates, and then the rotating rod 402 drives the spiral blade 403 to rotate. At this time, the material falls into the conveying cylinder 401 through the discharge pipe of the feed box 3, and the spiral blade 403 rotates to convey the material. When the material moves to the discharge pipe 408, it falls into the guide pipe 6 and falls onto the top plate 506. After the weight sensor 505 senses the specified weight, the second motor 510 is started, and the gear 501 engages the racks 502 on both sides, and then the two racks 502 drive the slide plate 503 to move relatively. At this time, the slide plate 503 drives the weighing plate 509 to move, so that the material falls into the crushing box for crushing.
