The two sliders are slidably mounted in the frame, and the threaded holes on the two sliders are matched with the lead screw threads; the first transition box 310 is slidably mounted on the slide groove 308, and the first transition box 310 and the lead screw slider group I 30 9; the second transition box 311 is slidably mounted on the slide 308, the second transition box 311 is fixedly connected to the side of a slider in the lead screw slider group I 309, the lower end outlet of the second transition box 311 is intermittently aligned with the upper end inlet of the Z-shaped tube 307, and the first transition box 310 and the second transition box 311 are intermittently aligned with the rear side of the inclined mesh plate 304. Specifically, when the coarsely crushed qualified particles enter the inclined frame 303, the finer particles will fall along the inclined mesh plate 304, and the qualified medium particles will enter the first extraction box 305. If the food does not need to be crushed into powder, the lead screw slider group I 309 works, driving the first transition box 310 and the second transition box 311 to move simultaneously, so that the second transition box 311 moves to the discharge port at the rear side of the inclined mesh plate 304. At this time, the lower end discharge port of the second transition box 311 is docked with the upper end of the Z-shaped tube 307. At this time, the small particle food falling along the inclined mesh plate 304 enters the second transition box 311, and enters the Z-shaped tube 307 along the second transition box 311 and finally enters the second drawer 306 for collection, and is taken out manually for detection;If the food needs to be crushed into powder, the lead screw slider group I 309 works, driving the first transition box 310 and the second transition box 311 to move simultaneously, so that the first transition box 310 moves to the discharge port on the rear side of the inclined mesh plate 304. At this time, the lower discharge port of the first transition box 310 and the circular hole on the annular plate I 407 can be intermittently aligned. At this time, the small particles of food falling along the inclined mesh plate 304 enter the first transition box 310 and wait for the material taking cylinder 408 to be quantitatively taken out and ground. ;

[0038] In an optional embodiment of the present invention, Figure 6 As shown, a large-hole mesh plate is fixedly installed on the upper end surface of the funnel box 302, and only the food that is knocked into smaller pieces can pass through this mesh plate.

[0039] Working principle: The equipment can crush food into medium particles, small particles and powder respectively, and output them separately to meet the needs of different forms during food testing; the equipment can freely choose whether to grind food into powder, which is highly flexible and effectively improves the utilization rate of the equipment; when grinding food into powder, the equipment can quantitatively transfer the small particles of food that need to be ground multiple times, ensuring the grinding effect while saving manpower; When the food is coarsely crushed, firstly, the food to be crushed is manually put into the equipment from the upper entrance of the hollow cylinder 201. At this time, the food falls into the middle position of the two knocking plates 209 along the transition box I 210. At this time, the motor I 207 is started to drive the gear set 206 to rotate, and the gear set 206 drives the two vertical plates 203 to rotate in opposite directions at the same time. The two vertical plates 203 push the two push plates 205 to move back and forth at the same time, and the two push plates 205 drive the two knocking plates 209 to move back and forth at the same time. At this time, the two knocking plates 209 move inward at the same time to crush the food in the hollow cylinder 201. The food particles that meet the standards enter the inclined frame 303 along the large-hole mesh plate on the funnel box 302, and the food that does not meet the standards will stay in the hollow cylinder 201 and be crushed until all the food is knocked into particles of appropriate size and enters the inclined frame 303. When the coarsely crushed qualified particles enter the inclined frame 303, the finer particles will fall along the inclined mesh plate 304, and the qualified medium particles will enter the first drawer 305 and be taken away manually for inspection; if the food does not need to be crushed into powder, the screw slider group I 309 will work, driving the first transition box 310 and the second transition box 311 to move at the same time, so that the second transition box 311 moves to the discharge port on the rear side of the inclined mesh plate 304. At this time, the lower end discharge port of the second transition box 311 is connected to the upper end of the Z-shaped tube 307. At this time, the small particle food falling along the inclined mesh plate 304 enters the second transition box 311, and enters the Z-shaped tube 307 along the second transition box 311 and finally enters the second drawer 306 for collection and is manually taken out for inspection; if the food needs to be crushed into powder, the lead screw slider group I 309 works to drive the first transition box 310 and the second transition box 311 to move simultaneously, so that the first transition box 310 moves to the discharge port on the rear side of the inclined mesh plate 304. At this time, the discharge port at the lower end of the first transition box 310 and the circular hole on the annular plate I 407 can be intermittently aligned. At this time, the small particles of food falling along the inclined mesh plate 304 enter the first transition box 310 and wait for the material taking barrel 408 to be quantitatively taken out and ground; When the food is finally ground, first the motor II 405 is started, driving the large gear I 403 to rotate, the large gear I 403 drives the large gear II 404 to rotate, the large gear II 404 rotates one circle and drives the round rod 406 to rotate one circle, the round rod 406 rotates one circle and drives the annular plate I 407 to rotate one circle, when the annular plate I 407 rotates 180°, the annular plate I 407 drives the material taking barrel 408 to rotate 180°, at which time the material taking barrel 408 transports the food particles stored in it to the large circular hole of the motor II 405, at which time the food particles in it enter the eccentric feeding port on the upper grinding disc 503 along the large circular hole on the annular plate II 504; At the same time, the rotation of the large gear I 403 will drive the upper grinding disc 503 to rotate. The upper grinding disc 503 cooperates with the lower grinding disc 502 to grind the food particles put into the upper grinding disc 503 into powder. The food powder enters the third drawer 505 along the inclined surface of the annular box 501 for collection. When the large gear I 403 rotates to the position without gear teeth and contacts the small gear on the upper grinding disc 503, the large gear I 403 continues to rotate, and the upper grinding disc 503 is in a pause state. At this time, the eccentric feed port on the upper grinding disc 503 is aligned with the large circular hole on the annular plate II 504. At the same time, the gear teeth on the large gear II 404 are aligned with the small gear on the annular plate II 504. The small gear on the round rod 406 is meshed, driving the round rod 406 to rotate, and then driving the annular plate I 407 to rotate one circle. When the annular plate I 407 rotates 180°, the annular plate I 407 drives the material taking barrel 408 to rotate 180°. At this time, the material taking barrel 408 transports the food particles filled in it to the large circular hole of the motor II 405. At this time, the food particles in it enter the eccentric feed port on the upper grinding disc 503 along the large circular hole on the annular plate II 504; in this reciprocating operation, the eccentric feed port on the upper grinding disc 503 is intermittently cycled and quantitatively fed with food particles, which ensures the grinding effect of the equipment while saving manpower; When cleaning the inclined surface in the annular box 501, first the lead screw slider group II 506 works to drive the electric cylinder 507 to move, and the electric cylinder 507 drives the brush at the end of its piston rod to enter the annular box 501, and the lead screw slider group II 506 continues to work. At this time, the electric cylinder 507 slowly extends or shortens according to the curvature of the annular box 501, and then drives the brush at the end of its piston rod to clean along the inclined groove of the annular box 501, and finally all the food powder on the inclined surface of the annular box 501 is cleaned and collected in the third drawer 505, and the third drawer 505 is manually taken for further inspection of the food powder inside, thereby improving work efficiency.
