[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1、In the present application, the kitchen waste is placed in the material box, the motor one is started to drive the screw rod one to rotate, the screw rod one drives the material box to reciprocate left and right, the kitchen waste in the material box falls evenly from the guide plate on the lower crushing roller, the motor three is started to drive the square rod two to rotate, the square rod two drives the square rod one to rotate through the connecting ring, and the square rod one drives the two crushing rollers to rotate relatively, so that the kitchen waste is conveniently crushed, the material box is arranged to avoid that a large amount of kitchen waste is once put from one place to cause the crushing roller to be blocked or the kitchen waste crushed by the crushing roller to fall on the same position of the lower filter plate, and the filter plate is blocked.

[0021] 2、In the present application, when the kitchen waste is crushed, the motor two is started to drive the screw rod two to rotate, the screw rod two drives the front slide block, the scraping strip and the rear slide block to slide synchronously left and right, the scraping strip is arranged to scrape the viscous slurry waste accumulated on the filter plate, so that the viscous slurry waste passes through the filter hole of the filter plate and flows into the lower collecting box, the filter plate is prevented from being blocked, the filter plate is ensured to be unobstructed, and the crushed kitchen waste can be normally filtered and collected.

[0022] 3、In the present application, when the scraping strip moves left and right, the two cleaning rods on the two sides also move synchronously, when the cleaning rod moves to the position directly above the filter hole of the filter plate, the motor two stops working, the hydraulic cylinder one is started to drive the connecting plate and the cleaning rod to descend synchronously, the cleaning rod penetrates the filter hole of the filter plate, the viscous slurry waste in the filter hole is conveniently dredged, the filter plate is ensured to be unobstructed, and the crushed viscous slurry waste is conveniently and smoothly screened and collected.

[0023] 4. In this invention, after the cleaning rod penetrates the filter hole, the hydraulic cylinder two is activated to drive the pressure plate to rise. The pressure plate squeezes the airbag two, causing the gas inside the airbag two to enter the airbag one through the channel inside the cleaning rod. At this time, the airbag one expands. Since the cleaning rod will adhere to the lower end of the cleaning rod and the surface of the airbag one when it penetrates the filter hole on the filter plate, the expanded airbag one will be hooked by the lower end face of the filter hole. As the cleaning rod rises and resets, the outer surface of the airbag one undergoes adaptive deformation under the squeezing force of the lower end face of the filter hole, which facilitates the scraping off of the viscous slurry waste adhering to the outer surface of the airbag one. This reduces the situation where the viscous slurry waste blocks the filter hole, and also reduces the situation where the viscous slurry waste adhering to the lower end of the cleaning rod is brought back to the upper side of the filter plate when the cleaning rod resets after clearing the viscous slurry waste in the filter hole. This improves the cleaning effect of the cleaning rod on the filter hole.

[0024] 5. In this invention, when the scraper moves back and forth, it also drives the pusher to move synchronously. The pusher will contact and push the sealing plates on both sides in advance. The sealing plates drive the connecting rod to move outward, compressing the second spring and opening the through groove. At this time, the viscous slurry waste accumulated on both sides of the scraper can fall from the through groove into the lower collection box and the side of the partition that is far away from each other. This avoids the accumulation of a large amount of non-slurry waste, which cannot pass through the filter holes on the filter plate in time and cause blockage. It ensures that the viscous slurry waste after subsequent crushing can pass through the filter holes smoothly. At the same time, it is also convenient to shake off the non-slurry waste adhering to the lower end of the cleaning rod and the first air bag. This ensures that when the cleaning rod cleans the filter holes, the cleaning rod and the first air bag will not adhere to the non-slurry waste, causing blockage of the filter holes. It also avoids the situation where the non-slurry waste adhering to the surface of the cleaning rod and the first air bag is repeatedly carried back to the upper surface of the filter plate.

[0025] 6. In this invention, the scraper also drives the top strip to move left and right synchronously. The top strip is blocked by the protrusion plate, which causes the top strip to slide and rise on the slider, compressing the first spring. When the top strip separates from the protrusion on the protrusion plate, the first spring drives the scraper and the top strip to return to their original position downwards. The screw rotates in both directions, which makes the scraper and the top strip move up and down continuously. The lower end of the scraper continuously hits the filter plate, which helps to shake off the non-slurry waste adhering to the scraper into the lower channel and collection box, ensuring that the upper surface of the filter plate is not blocked by non-slurry waste and ensuring the smooth flow of the filter plate.

[0026] 7. In this invention, when the scraper and top bar move up and down, they will also drive the push bar to move up and down synchronously. The push bar will slide up and down in an abutting and fitting manner on the surface of the sealing plate, so that the sealing plate will not reset and close the through groove. Rotate the fixing screw to separate it from the filter plate and pull the filter plate out of the crushing box, which makes it convenient to disassemble and clean the filter plate, and replace it with a clean filter plate for fixed use.

[0027] 8、In the application, the rotation of the two sides of the screw three drives the horizontal strip and the connecting ring to move away from each other, the connecting ring is separated from the two sides of the square rod one, at this time, the square rod one and the square rod two are in a separated state, then rotating the screw four drives the lifting plate, the square rod one and the crushing roller to descend synchronously to the lower side of the crushing box, which facilitates the staff to clean the impurities and waste adhered to the crushing roller, ensures the neatness of the crushing roller, effectively improves the crushing and pulping quality of the subsequent kitchen waste, after cleaning, the crushing roller is reset and installed, the operation is simple and convenient, and the working efficiency is high.

[0045] As one embodiment of the present application, a dredging mechanism for dredging the viscous slurry accumulated on the filter plate 3 is also provided, which comprises a scraping strip 9 abuttingly arranged on the filter plate 3, a cleaning rod 10 slidingly installed on the scraping strip 9 corresponding to the filter holes on the filter plate 3, a connecting plate 11 fixedly installed on the upper end of the cleaning rod 10, a hydraulic cylinder I 12 fixedly installed on the lower end of the connecting plate 11, a hydraulic cylinder II 16 fixedly installed on the upper end of the pressure plate 15, a spring I 20 fixedly installed between the scraping strip 9 and the sliding block 17, a screw rod II 18 threadedly installed on the front sliding block 17, a motor II 19 provided on the right end of the screw rod II 18, a motor III 30 provided on the right end of the right square rod II 29, a connecting ring 31 sleeved between the left square rod I 28 and the right square rod II 29, a horizontal strip 32 fixedly installed between the connecting rings 31, a screw rod III 33 threadedly installed on the horizontal strip 32, a lifting plate 34 slidingly installed on the left end of the left square rod I 28, and a screw rod IV 35 threadedly installed on the right end of the right lifting plate 34.

[0046] When working, the second motor 19 drives the screw 18 to rotate, and the screw 18 drives the front sliding block 17, the scraping strip 9 and the rear sliding block 17 to slide synchronously, the scraping strip 9 is arranged to facilitate scraping the viscous slurry waste accumulated on the filter plate 3, and the viscous slurry waste can pass through the filter hole of the filter plate 3 and flow into the lower collecting box 1, so that the filter plate 3 is prevented from being blocked, the smoothness of the filter plate 3 is ensured, and the broken kitchen waste can be normally filtered and collected. When the scraping strip 9 moves left and right, the cleaning rod 10 on both sides moves synchronously. When the cleaning rod 10 moves to the top of the filter hole of the filter plate 3, the second motor 19 stops working, the connecting plate 11 and the cleaning rod 10 are driven by the first hydraulic cylinder 12 to descend synchronously, the cleaning rod 10 penetrates the filter hole of the filter plate 3, so that the viscous slurry waste in the filter hole is dredged, the smoothness of the filter plate 3 is ensured, and the broken viscous slurry waste is conveniently and smoothly screened and collected. When the cleaning rod 10 penetrates the filter hole, the pressure plate 15 is driven by the second hydraulic cylinder 16 to rise, the pressure plate 15 extrudes the air bag 14, so that the gas in the air bag 14 enters the air bag 13 through the channel in the cleaning rod 10. At this time, the air bag 13 expands and becomes larger. When the cleaning rod 10 penetrates the filter hole of the filter plate 3, the lower end of the cleaning rod 10 and the surface of the air bag 13 are adhered with viscous slurry waste, the expanded air bag 13 is hooked by the lower end surface of the filter hole, and the air bag 13 is self-adapted to deform under the extrusion of the lower end surface of the filter hole when the cleaning rod 10 rises and resets, so that the viscous slurry waste adhered to the surface of the air bag 13 is scraped off, thereby reducing the blockage of the filter hole by the viscous slurry waste and reducing the situation that the viscous slurry waste adhered to the lower end of the cleaning rod 10 is brought back to the upper side of the filter plate 3 when the cleaning rod 10 is reset after dredging the viscous slurry waste in the filter hole, thereby improving the dredging effect of the cleaning rod 10 on the filter hole. When the scraping strip 9 reciprocally scrapes left and right, the pushing strip 27 moves synchronously, the pushing strip 27 contacts and pushes the sealing plate 24 in advance, the sealing plate 24 drives the connecting rod 25 to move outward, and the spring 26 is compressed to open the through slot 23. At this time, the viscous slurry waste accumulated on both sides of the scraping strip 9 can fall into the lower collecting box 1 and the side away from the partition plate 101, so that a large amount of non-pulp waste cannot pass through the filter hole of the filter plate 3 in time, the filter hole is prevented from being blocked, the broken viscous slurry waste can smoothly pass through the filter hole, the non-pulp waste adhered to the lower end of the cleaning rod 10 and the air bag 13 can be shaken off together, the cleaning rod 10 and the air bag 13 are prevented from adhering to the non-pulp waste when the cleaning rod 10 cleans the filter hole, the filter hole is prevented from being blocked, and the non-pulp waste adhered to the surface of the cleaning rod 10 and the air bag 13 is prevented from being repeatedly brought back to the upper end of the filter plate 3. At the same time, the scraping strip 9 drives the top strip 21 to move left and right synchronously.The top strip 21 is blocked by the bump plate 22, thereby making the top strip 21 drive the scraping strip 9 to slide on the sliding block 17 and compress the spring I 20, when the top strip 21 is separated from the bump on the bump plate 22, the spring I 20 drives the scraping strip 9 and the top strip 21 to reset downwards, the screw II 18 rotates reversely, so that the scraping strip 9 and the top strip 21 continuously move up and down, the lower end of the scraping strip 9 continuously hits the filter plate 3, which is beneficial to shake the non-pulping waste adhered on the scraping strip 9 to fall into the through groove 23 and the collecting box 1 below, so that the upper surface of the filter plate 3 is not blocked by the non-pulping waste, and the smoothness of the filter plate 3 is ensured, when the scraping strip 9 and the top strip 21 move up and down, the pushing strip 27 also synchronously moves up and down, the pushing strip 27 slides up and down on the surface of the sealing plate 24 in a butt-abutting mode, and the sealing plate 24 does not reset to close the through groove 23, the fixed screw 301 is rotated to separate the filter plate 3 from the crushing box 2, so that the filter plate 3 is pulled out from the crushing box 2, the filter plate 3 is conveniently disassembled and cleaned, and the clean filter plate 3 is replaced and fixed for use, the screw III 33 on the two sides is rotated to drive the horizontal strip 32 and the connecting ring 31 to move away from each other, the connecting ring 31 is separated from the square rod I 28 on the two sides, the square rod I 28 is in a separated state with the square rod II 29, the screw IV 35 is further rotated to drive the lifting plate 34, the square rod I 28 and the crushing roller 4 to synchronously descend to the lower side of the crushing box 2, so that the worker can clean the impurities and waste adhered on the crushing roller 4, the cleanliness of the crushing roller 4 is ensured, and the crushing and pulping quality of the subsequent kitchen waste is effectively improved, after cleaning, the crushing roller 4 is reset and installed, the operation is simple and convenient, and the working efficiency is high.

[0047] Working principle:

[0048] When the kitchen waste is used, the kitchen waste is placed in the material box 6, the motor I 8 is started to drive the screw I 7 to rotate, the screw I 7 drives the material box 6 to reciprocate left and right, and the kitchen waste in the material box 6 falls on the crushing roller 4 below through the guide plate 5, the motor III 30 is started to drive the square rod II 29 to rotate, the square rod II 29 drives the square rod I 28 to rotate through the connecting ring 31, and the square rod I 28 drives the two crushing rollers 4 to relatively rotate, so that the kitchen waste is conveniently crushed, and the material box 6 is arranged to avoid that a large amount of kitchen waste is once put from one place, the crushing roller 4 is blocked, or the kitchen waste crushed by the crushing roller 4 falls on the same position of the filter plate 3 below, and the filter plate 3 is blocked.

[0049] When the kitchen waste is broken, the motor 2 19 is started to drive the screw 2 18 to rotate, and the screw 2 18 drives the front sliding block 17, the scraping strip 9 and the rear sliding block 17 to slide synchronously left and right. The scraping strip 9 is arranged to facilitate scraping the viscous slurry waste accumulated on the filter plate 3, so as to facilitate the viscous slurry waste to pass through the filter hole of the filter plate 3 and flow into the collection box 1 below, avoiding the blockage of the filter plate 3 and ensuring the smoothness of the filter plate 3 to normally filter and collect the broken kitchen waste.

[0050] When the scraping strip 9 moves left and right, the cleaning rod 10 on both sides will also move synchronously. When the cleaning rod 10 moves to the top of the filter hole of the filter plate 3, the motor 2 19 stops working, and the hydraulic cylinder 1 2 is started to drive the connecting plate 1 1 and the cleaning rod 10 to descend synchronously. The cleaning rod 10 penetrates the filter hole of the filter plate 3, facilitating the dredging of the viscous slurry waste in the filter hole and ensuring the smoothness of the filter plate 3 to conveniently and smoothly sieve and collect the broken viscous slurry waste.

[0051] When the cleaning rod 10 penetrates the filter hole, the hydraulic cylinder 2 16 is started to drive the pressing plate 1 5 to rise, and the pressing plate 1 5 extrudes the air bag 2 14 to make the gas in the air bag 2 14 enter the air bag 1 3 through the channel in the cleaning rod 10. At this time, the air bag 1 3 expands and becomes larger. When the cleaning rod 10 penetrates the filter hole of the filter plate 3, the lower end of the cleaning rod 10 and the surface of the air bag 1 3 will be attached with viscous slurry waste. The expanded air bag 1 3 will be hooked by the lower end face of the filter hole. With the cleaning rod 10 rising and resetting, the outer surface of the air bag 1 3 is subjected to the extrusion force of the lower end face of the filter hole and is self-adaptively deformed, so as to facilitate the viscous slurry waste attached to the outer surface of the air bag 1 3 to fall off, thereby reducing the situation that the viscous slurry waste blocks the filter hole and reducing the situation that the viscous slurry waste attached to the lower end of the cleaning rod 10 is brought back to the upper side of the filter plate 3 when the cleaning rod 10 resets after dredging the viscous slurry waste in the filter hole, thereby improving the dredging effect of the cleaning rod 10 on the filter hole.

[0052] When the scraping strip 9 reciprocates, the pushing strip 27 will also move synchronously, and the pushing strip 27 will contact and push the two side sealing plates 24 in advance, and the sealing plate 24 will drive the connecting rod 25 to move outward, and the spring 26 will be compressed at the same time, so that the through slot 23 is opened, and the viscous slurry waste accumulated on the left and right sides of the scraping strip 9 can fall into the collection box 1 on the side away from the partition plate 101, thereby avoiding the accumulation of a large amount of non-pulping waste, which cannot pass through the filter hole of the filter plate 3 in time, causing blockage, ensuring that the viscous slurry waste after crushing can pass through the filter hole smoothly, and also facilitating the shaking of the non-pulping waste adhered to the lower end of the cleaning rod 10 and the air bag 13, so that the cleaning rod 10 and the air bag 13 do not adhere to the non-pulping waste when cleaning the filter hole, causing blockage of the filter hole, and avoiding the situation that the non-pulping waste adhered to the surface of the cleaning rod 10 and the air bag 13 is reciprocated and brought back to the upper end surface of the filter plate 3.

[0053] At the same time, the scraping strip 9 will also drive the top strip 21 to move synchronously, and the top strip 21 will be blocked by the protruding block plate 22, so that the top strip 21 drives the scraping strip 9 to slide upward on the sliding block 17 and compresses the spring 20. When the top strip 21 and the protruding block on the protruding block plate 22 are separated, the spring 20 drives the scraping strip 9 and the top strip 21 to reset downward, and the screw rod 18 rotates in the opposite direction, so that the scraping strip 9 and the top strip 21 move up and down continuously, and the lower end of the scraping strip 9 continuously hits the filter plate 3, which is conducive to shaking the non-pulping waste adhered to the scraping strip 9 into the through slot 23 and the collection box 1 below, ensuring that the upper surface of the filter plate 3 is not blocked by the non-pulping waste, and ensuring the smoothness of the filter plate 3. When the scraping strip 9 and the top strip 21 move up and down, the pushing strip 27 will also move up and down synchronously, and the pushing strip 27 will slide up and down on the surface of the sealing plate 24 in a butt joint manner, and the sealing plate 24 will not be reset to close the through slot 23.

[0054] Rotating the fixed screw rod 301 to separate it from the filter plate 3, the filter plate 3 is pulled out of the crushing box 2, which is convenient for disassembling and cleaning the filter plate 3, and replacing the clean filter plate 3 for fixed use. Rotating the screw rod 33 on both sides drives the horizontal strip 32 and the connecting ring 31 to move away from each other, and the connecting ring 31 is separated from the square rod 28 on both sides. At this time, the square rod 28 and the square rod 29 are in a separated state, and rotating the screw rod 35 drives the lifting plate 34, the square rod 28 and the crushing roller 4 to descend synchronously to the lower side of the crushing box 2, which is convenient for workers to clean the impurities adhered to the crushing roller 4, ensuring the cleanliness of the crushing roller 4 and effectively improving the crushing and pulping quality of the subsequent kitchen waste.
