[0030] Since the gaps between the vegetables to be crushed are relatively large and their fluidity is relatively poor, after the vegetables enter the feed hopper 14, they are easily stacked in the inner cavity of the feed hopper 14, making it inconvenient to unload the vegetables. By providing a pushing device 13, the vegetables stacked in the inner cavity of the feed hopper 14 can be squeezed to reduce the space occupied by the vegetables, and the squeezed vegetables can be pushed toward the feed drive device 12, making it convenient for the feed drive device 12 to drive the vegetable material in the feed hopper 14 to move downward.

[0031] Working process:

[0032] During operation, the driving motor in the crushing driving device 1 is started to drive the crushing knife device 7 to rotate, and the discharging motor 5-1 is started to drive the rectangular scraper frame 5-5 to rotate;

[0033] The vegetables to be crushed are poured into the feed hopper 14, and the roller motor 12-1 and the push drive cylinder 13-2 are started. The piston rod of the push drive cylinder 13-2 is extended to drive the push plate 13-4 to flip toward the feed drive device 12, thereby squeezing the vegetables poured into the feed hopper 14, and pushing the squeezed vegetable mass toward the feed drive device 12. The started roller motor 12-1 and the roller transmission pair 12-3 work together to drive multiple groups of feed rollers 12-2 to rotate synchronously, thereby pushing the vegetables downward to prevent the vegetables from accumulating and blocking the discharge port of the feed hopper 14;

[0034] In conjunction with the fixed crushing knife 10, the rotating crushing knife device 7 can cut and crush the vegetables pushed downward by the feed drive device 12. The crushed vegetables fall onto the arc filter 6 and are filtered and screened by the arc filter 6. The materials that meet the particle size requirements fall downward after screening by the arc filter 6, and the materials that do not meet the particle size requirements are retained on the arc filter 6; during the crushing process, the rotating rectangular scraper frame 5-5 can drive the two groups of discharging scrapers 5-3 thereon to flip around the scraper shaft 5-4, and then scrape and push the materials that fall to the bottom surface of the inner cavity of the discharging hopper 3 downward, so that the materials move toward the discharging port 4, thereby avoiding material accumulation and blockage causing unsmooth discharging.
