[0035] See also Figures 1 to 7 As shown, a raw beef cleaning device comprises: a cleaning mechanism 1 for cleaning beef and a spraying mechanism 2 for removing residual impurities on the surface of the beef after cleaning and a cleaning liquid.

[0036] The cleaning mechanism 1 includes a first frame 11, a first conveyor belt 12, a second conveyor belt 13 and a kneading mechanism. The first frame 11 is provided with a first inlet 111 and a first outlet 112 at the front and rear ends, respectively. The first conveyor belt 12 is fixedly connected to the first inlet 111. The first conveyor belt 12 can convey raw beef to the kneading mechanism in the cleaning mechanism 1. The second conveyor belt 13 is provided at the first outlet 112. The second conveyor belt 13 can convey the raw beef cleaned by the cleaning mechanism 1 to the spraying mechanism 2. The kneading mechanism is installed inside the first frame 11. Specifically, the first frame 11 is provided with a water inlet 113 and a drain outlet 114. It can be understood that the cleaning liquid can be conveyed into the cleaning mechanism 1 through the water inlet 113 so that the cleaning liquid at least immerses the lower kneading conveyor belt 141 of the kneading mechanism. The drain outlet 114 can discharge the contaminated cleaning liquid in the cleaning mechanism 1 out of the cleaning mechanism 1. Correspondingly, the cleaning liquid is water or a weak alkaline aqueous solution containing baking soda.

[0037] The kneading mechanism includes a lower kneading conveyor belt 141, a first driving motor 142, an upper kneading conveyor belt 143, a squeezing assembly and a linkage assembly. The lower kneading conveyor belt 141 is fixedly connected to the inside of the first frame 11, the upper kneading conveyor belt 143 is connected to the inside of the first frame 11 through the squeezing assembly, and the upper kneading conveyor belt 143 is located above the lower kneading conveyor belt 141. Specifically, the squeezing assembly includes a first cylinder 151, a spring 152, a connecting plate 153 and a second cylinder 154. The upper kneading conveyor belt 143 and the connecting plate 153 are connected by the first cylinder 151, and the spring 152 is wrapped around the outside of the first cylinder 151. One end of the spring 152 is connected to the upper kneading conveyor belt 143, and the other end is connected to the connecting plate 153. It can be understood that the first cylinder 151 is used to lock and release the spring 152, and the connecting plate 153 is connected to the first frame 11 through the second cylinder 154, that is, the second cylinder 154 can shrink when the raw beef enters between the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143 of the kneading mechanism, and is used to adjust the distance between the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143, so that the kneading mechanism can rub the beef without damaging the raw beef due to the small distance between the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143.

[0038] Specifically, the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143 are both provided with corresponding raised portions 144 and recessed portions 145. It can be understood that the raised portion 144 on the lower kneading conveyor belt 141 cooperates with the recessed portion 145 on the upper kneading conveyor belt 143, and the recessed portion 145 on the lower kneading conveyor belt 141 and the raised portion 144 on the lower kneading conveyor belt 141 can make the raw beef be kneaded when it moves in the gap between the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143, so as to facilitate the outflow of blood inside the raw beef and the dissolution of blood clots.

[0039] The active roller of the lower kneading conveyor belt 141 is connected to the first driving motor 142, and the active shaft of the lower kneading conveyor belt 141 is connected to the active shaft of the upper kneading conveyor belt 143 through a linkage assembly. It can be understood that the first driving motor 142 can drive the active roller of the lower kneading conveyor belt 141 to rotate, thereby driving the conveyor belt on the lower kneading conveyor belt 141 to rotate, and the linkage assembly can realize the synchronous operation of the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143 through gears. Correspondingly, the linkage assembly includes a telescopic shaft 161, a first shaft sleeve 162 and a second shaft sleeve 163, the first shaft sleeve 162 is arranged on the lower kneading conveyor belt 141, and the second shaft sleeve 163 is arranged on the upper kneading conveyor belt 143, and the two ends of the telescopic shaft 161 are rotatably arranged in the first shaft sleeve 162 and the second shaft sleeve 163 respectively, and the active roller of the lower kneading conveyor belt 141 and the active roller of the upper kneading conveyor belt 143 are connected through the telescopic shaft 161 and the gear. It can be understood that the telescopic shaft 161 can ensure that the active roller of the lower kneading conveyor belt 141 and the active roller of the lower kneading conveyor belt 141 remain connected during the up and down movement of the upper kneading conveyor belt 143.

[0040] The spray mechanism 2 includes a second frame 21, a third conveyor belt 22, a meat hanging mechanism, a water distribution pipe 24 and a spray head 241. The second frame 21 is provided with a second inlet 211 and a second outlet 212 at the front and rear ends, respectively. The first frame 11 and the second frame 21 are fixedly connected. The second conveyor belt 13 extends into the second frame 21 through the second inlet 211. The meat hanging mechanism is arranged in the second frame 21. Specifically, the meat hanging mechanism includes a second driving motor 231, a pulley 232, a synchronous toothed belt 233 and a slider 234. The second driving motor 231 is connected to the pulley 232 through a transmission shaft. The synchronous toothed belt 233 is arranged on the pulley 232. The slider 234 is fixedly arranged on the synchronous toothed belt 233. It can be understood that the second driving motor 231 can drive the synchronous toothed belt 233 and the slider 234 on the synchronous toothed belt 233 to rotate through the pulley 232. Specifically, the meat hanging mechanism further includes a hook 235 and a torsion spring 237. The hook 235 is rotatably arranged on the slider 234. The torsion spring 237 is arranged on the hook 235. One end of the hook 235 is connected to the hook 235, and the other end is connected to the slider 234. Specifically, the meat hanging mechanism further includes a slide rail 238. The slide rail 238 is fixedly connected to the second frame 21. Correspondingly, the hook 235 is provided with a slide bar 236 that cooperates with the slide rail 238. It can be understood that the hook 235 is in a pop-up state under the elastic force of the torsion spring 237, and can hook the raw beef on the second conveyor belt 13 and move to the third conveyor belt 22 with the slider 234. When the slide bar 236 contacts the slide rail 238, the slider 234 continues to move, and the hook 235 is flipped upward to a retracted state under the action of the slide rail 238. After the hook 235 is completely retracted, the raw beef slides from the hook 235 to the third conveyor belt 22 under the action of gravity.

[0041] The water distribution pipe 24 is fixedly connected to the inner wall of the second frame 21, and a nozzle 241 is provided on the water distribution pipe 24. The third conveyor belt 22 is arranged at the second outlet 212, that is, the water distribution pipe 24 is connected to the water supply pipe, and clean water can be sprayed to the raw beef in the spray mechanism 2 through the nozzle 241 to remove residual impurities and cleaning liquid on its surface.

[0042] Working principle of the present invention:

[0043] First, before washing the raw beef, clean washing liquid is injected into the washing mechanism 1 through the water inlet 113 until the washing liquid at least immerses the lower kneading conveyor belt 141, preferably, the upper kneading conveyor belt 143 is immersed in the washing liquid; the first cylinder 151 is contracted and locked, and the spring 152 is locked; the raw beef is placed on the first conveyor belt 12 manually or by a conveyor belt, and the first conveyor belt 12 conveys the raw beef to the lower kneading conveyor belt 141 inside the washing mechanism 1; the beef enters the gap between the upper kneading conveyor belt 143 and the lower kneading conveyor belt 141, and while being immersed in the washing liquid, it pushes the upper kneading conveyor belt 143 to move upward, and the second cylinder 154 is compressed. After the raw beef completely enters the gap, the second cylinder 154 is locked, and the first cylinder 151 is released. The spring 152 releases its elastic force and stretches, pushing the upper kneading conveyor belt 143 to move downward, squeezing the raw beef; the first drive motor 142 drives the lower kneading conveyor belt 141 to rotate, and drives the upper kneading conveyor belt 143 to operate synchronously through the linkage component, driving the beef to move in the gap between the lower kneading conveyor belt 141 and the upper kneading conveyor belt 143, the raw beef is soaked in the cleaning liquid, and the impurities on the surface are removed under the friction of the upper kneading conveyor belt 143 and the lower kneading conveyor belt 141; when passing through the raised part 144 and the depressed part 145 on the conveyor belt, the raw beef is squeezed and kneaded, so that the blood inside it flows out, and the blood clots are dissolved and flow out under the kneading and cleaning immersion; the raw beef kneaded and cleaned by the cleaning mechanism 1 is conveyed to the spray mechanism 2 by the second conveyor belt 13.

[0044] After the raw beef is conveyed to the spray mechanism 2 by the second conveyor belt 13, the second drive motor 231 drives the slider 234 and the hook 235 installed on the slider 234 to move above the raw beef. During the movement, after the slide bar 236 disengages from the slide rail 238, the torsion spring 237 releases its elastic force, pushing the hook 235 to pop out, so that the front end of the hook 235 hooks the raw beef, and under the drive of the second drive motor 231, it moves toward the third conveyor belt 22 together with the slider 234; during the movement of the raw beef, the nozzle 241 sprays clean water on it to wash away the impurities and contaminated cleaning liquid remaining on the surface of the raw beef; the slider 234 moves until the slide bar 236 on the hook 235 contacts the slide rail 238, and the hook 235 flips upward to a retracted state under the action of the slide rail 238. After the hook 235 is completely retracted, the raw beef slides from the hook 235 to the third conveyor belt 22 under the action of gravity; then the third conveyor belt 22 conveys the cleaned raw beef to the outside of the spray mechanism 2 for further deep processing.
