Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0026] In one embodiment, such as Figures 1-3 As shown, a food safety testing crusher includes a crushing chamber 100 and a crushing mechanism. The crushing mechanism is located inside the crushing chamber 100 and includes a crushing component 300 and two guide plates 200. The two guide plates 200 are symmetrically arranged on the inner wall of the crushing chamber 100, and the crushing component 300 is located between the two guide plates 200. The crushing component 300 includes a lower screen strip 320 and two side pressure plates 310. The lower screen strip 320 is located between the two side pressure plates 310, and one end of the side pressure plates 310 is rotatably connected to the side portion of the lower screen strip 320. Each of the opposite end faces of the two side pressure plates 310 is provided with a crushing disc 311 that rotatably engages with it. The surface has multiple crushing spikes 313. The end of the side pressure plate 310 away from the lower screen strip 320 is hinged to an upper sliding part 330, and the upper sliding part 330 slides with the bottom of the guide plate 200. The upper sliding part 330 is provided with a pressing push rod 400 that slides through the side wall of the crushing box 100. It also includes a pressing drive part 500, which is connected to two pressing push rods 400. The pressing drive part 500 is used to synchronously drive the two pressing push rods 400 to move relative to each other or away from each other. The upper sliding part 330 is also connected to multiple crushing discs 311 through a connecting component. When the upper sliding part 330 moves on the guide plate 200, the connecting component can drive the multiple crushing discs 311 to rotate synchronously.

[0027] In this embodiment of the invention, the food for testing is placed inside the crushing chamber 100 through the top port of the crushing chamber 100. Guided by the surfaces of the two guide plates 200, the food falls into the crushing assembly 300. The crushing drive unit 500 drives the two crushing push rods 400 to move relative to each other. The crushing push rods 400 push the upper sliding parts 330 to move at the bottom of the guide plates 200. The two upper sliding parts 330 respectively push the two side pressure plates 310 to rotate closer together. The crushing spikes 313 on the side pressure plates 310 can pierce the food between the two side pressure plates 310, and the two upper sliding parts... When part 330 moves, the connecting component drives multiple crushing discs 311 on the side pressure plate 310 to rotate synchronously, so that the crushing spikes 313 on the crushing disc 311 can rotate relative to the food, thereby crushing the food. The two side pressure plates 310 come together to squeeze the food, and with the rotation of the crushing discs 311, the crushing effect of the food is improved. The crushed food falls to the bottom of the crushing box 100 through the lower screen strip 320. The bottom side wall of the crushing box 100 has a discharge port 110, which is used to discharge the crushed food.

[0028] In one embodiment, such as Figures 1-3As shown, each crushing disc 311 has a rotating rod 312 on its end face away from the crushing spike 313. The connecting component includes a rack assembly 314 and an inclined connecting rod 340. The rack assembly 314 is slidably mounted on the end face of the side pressure plate 310. Each rotating rod 312 is equipped with a gear 315, and multiple gears 315 mesh with the rack assembly 314. One end of the inclined connecting rod 340 is hinged to the rack assembly 314, and the other end is slidably mounted on the upper side pressure plate 310. The upper sliding part 330 is hinged in the middle. In this embodiment of the invention, when the upper sliding part 330 moves under the push of the extrusion push rod 400, the side pressure plate 310 rotates relative to the upper sliding part 330. Then, the upper sliding part 330 pushes the rack assembly 314 to slide on the side pressure plate 310 through the oblique connecting rod 340. The rack assembly 314 drives the rotating rod 312 to rotate through meshing with the gear 315. Thus, the crushing disc 311 can rotate when the upper sliding part 330 moves.

[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, the extrusion drive unit 500 includes a crushing motor 510, a turntable 520, a strip frame 540, and two connecting arms 550. The crushing motor 510 is mounted on the outer wall of the crushing chamber 100, and the turntable 520 is mounted on the output end of the crushing motor 510. The strip frame 540 is located on one side of the end face of the turntable 520, and the end of the strip frame 540 is slidably engaged with the side wall of the crushing chamber 100. The end face of the turntable 520 has an eccentric protrusion 530 extending into the strip frame 540. A vertical rod 570 is fixedly connected to the strip frame 540, and two connecting rods 560 with one end hinged to the top of the vertical rod 570 are provided. The two connecting arms 550 are slidably mounted on the crushing chamber 100. On the side wall of 00, one end of the connecting arm 550 is hinged to the end of the corresponding connecting rod 560 away from the vertical rod 570, and the other end of the connecting arm 550 is connected to the corresponding extrusion push rod 400. In this embodiment of the invention, the turntable 520 rotates under the drive of the crushing motor 510, the eccentric protrusion 530 rotates with the turntable 520 and reciprocates to move the strip frame 540 up and down, the vertical rod 570 moves with the strip frame 540 and the vertical rod 570 moves the two connecting arms 550 synchronously and in opposite directions through the two connecting rods 560; then the two extrusion push rods 400 drive the corresponding upper sliding part 330 to move under the drive of the two connecting arms 550.

[0030] In one embodiment, such as Figure 1 and Figure 5As shown, the bottom wall of the guide plate 200 has a connecting groove 210 and the upper sliding part 330 is slidably locked inside the connecting groove 210. The guide plate 200 is provided with at least one water spray hole 220. One end of the water spray hole 220 faces the side pressure plate 310 and the other end is connected to the water inlet connection end 230 provided on the outer wall of the crushing box 100. In this embodiment of the invention, the water inlet connection end 230 can be connected to an external water supply device. The water supply device pumps cleaning water through the water inlet connection end 230 into the water spray hole 220 and sprays it from the other end of the water spray hole 220 onto the side pressure plate 310, thereby cleaning the surface of the side pressure plate 310.

[0031] In one embodiment, such as Figure 1 As shown, the top port of the crushing chamber 100 is also provided with a top cover 600 and a pressure plate 700. One end of the top cover 600 is rotatably connected to the side wall of the crushing chamber 100. The pressure plate 700 is located inside the crushing chamber 100 and is connected to the top cover 600 by an elastic telescopic rod 800. The top of the top cover 600 has a handle 610. In this embodiment of the invention, when there is too much food concentrated on the upper side of the crushing component 300 or the detected food is large, the top cover 600 is closed on the top port of the crushing chamber 100. Under the elastic force of the elastic telescopic rod 800, the pressure plate 700 gradually presses down on the food on the upper side of the crushing component 300. After the crushing component 300 gradually crushes the food inside, the food on the upper side of the crushing component 300 can fall into the crushing component 300 under the pressure of the pressure plate 700, ensuring the continuity of crushing.

[0032] In one embodiment, such as Figure 1 and Figure 5 As shown, the upper surfaces of both guide plates 200 are inclined, and each guide plate 200 has a side push plate 900. The side push plate 900 slides on the inclined surface of the guide plate 200, and the side push plate 900 is connected to the side wall of the crushing chamber 100 by a first return spring 910. The two ends of the pressure plate 700 are also provided with lateral pushing members 710. During the downward movement of the pressure plate 700, the lateral pushing members 710 can push the side push plate 900 to overcome the elastic force of the first return spring 910 and move it along the guide plate 200. The inclined surface of the guide plate 200 moves toward the crushing and extruding assembly 300. In this embodiment of the invention, when the pressure plate 700 presses down on the food, the lateral pusher 710 can push the side pusher 900 toward the crushing and extruding assembly 300, so that the side pusher 900 pushes and extrudes the food on the guide plate 200 toward the crushing and extruding assembly 300, preventing the food from accumulating on the surface of the guide plate 200. When the pressure plate 700 moves up, the side pusher 900 is reset under the elastic force of the first reset spring 910.

[0033] In one embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, at least two slides 720 are provided on the lower end surface of the pressure plate 700. Each slide 720 has a slider 730 that slides inside it. The side of the slider 730 is connected to the side of the slide 720 by a second return spring 740. The lateral pusher 710 includes a lower pusher frame 750 and a pusher roller 760. The top of the lower pusher frame 750 is connected to the slider 730, and the lower end of the lower pusher frame 750 is provided with a pusher roller 760 that rotates with it. In this embodiment of the invention, when the pressure plate 700 moves downward, the lateral pusher 710 moves downward and the pusher roller 760 gradually contacts the upper surface of the guide plate 200. Since the upper surface of the guide plate 200 is inclined, the slider 730 moves inside the slide 720 under the push of the downward-moving pressure plate 700. As a result, the lower pusher frame 750 and the pusher roller 760 move laterally relative to the pressure plate 700, so that the pusher roller 760 can push the side pusher plate 900 to move.

[0034] The above embodiment provides a food safety testing crusher, wherein the extrusion drive unit 500 drives two extrusion push rods 400 to move relative to each other, the extrusion push rods 400 push the upper sliding part 330 to move at the bottom of the guide plate 200, the two upper sliding parts 330 respectively push the two side pressure plates 310 to rotate closer together, the crushing spikes 313 on the side pressure plates 310 can pierce the food between the two side pressure plates 310, and when the two upper sliding parts 330 move, the connecting parts drive the multiple crushing discs 311 on the side pressure plates 310 to rotate synchronously, so that the crushing spikes 313 on the crushing discs 311 can rotate relative to the food, thereby crushing the food, and the two side pressure plates 310 approaching each other can squeeze the food, and with the rotation of the crushing discs 311, the crushing effect of the food is improved; the crushed food falls to the bottom of the crushing box 100 through the lower screen strip 320.
