[0003] The solid part of kitchen waste can be directly used for composting or anaerobic digestion, while the liquid part can be converted into energy such as biogas through fermentation and other methods. Therefore, after the kitchen waste is crushed, it is necessary to separate the solid and liquid. In the existing technology, the solid and liquid of kitchen waste are often separated by sieve plates and drain plates, so that the solids remain on the sieve plate and the water flows through the sieve plate to the bottom. However, this will cause the solid waste to clog the pores of the sieve plate. Long strips of garbage such as vegetable leaves will be entangled in the pores of the sieve plate. Therefore, the problem of clogged pores cannot be completely solved by shaking or vibrating the sieve plate. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0023] See Figure 1-Figure 5 As shown, a kitchen waste cutting and crushing device includes a crushing device 1, a plurality of crushing rollers 3 are arranged inside the crushing device 1, a drum 5 is arranged below the crushing rollers 3, and a plurality of water leakage holes 9 are opened in the drum 5. A rotatable support rod 7 is arranged inside the crushing device 1, and a plurality of insertion rods 8 are installed on the outer wall of the support rod 7. When the support rod 7 rotates, the insertion rods 8 are inserted into the water leakage holes 9 and drive the drum 5 to rotate.
[0024] After being crushed by multiple crushing rollers 3, the kitchen waste falls into the drum 5. The liquid in the kitchen waste flows out through the drain hole 9, while the solid waste cannot pass through the drain hole 9. The aperture of the drain hole 9 is such that even if the kitchen waste is crushed, it cannot pass through the insertion rod 8 and flow out, thus achieving solid-liquid separation. However, a part of the crushed kitchen waste will block the drain hole 9. Therefore, the support rod 7 is driven to rotate. After the support rod 7 rotates, it drives the multiple insertion rods 8 to rotate together. The insertion rods 8 will continuously insert into the drain hole 9 during rotation, so the drain hole 9 can be dredged by the insertion rods 8.
[0025] After a row of rods 8 are inserted into the water leakage port 9, the rods 8 continue to rotate, pushing the water leakage port 9 to one side, and then the next group of rods 8 are inserted into the new water leakage port 9, causing the drum 5 and the water leakage port 9 to rotate together. Therefore, each water leakage port 9 can be cleaned, and the rotation of the drum 5 can reduce the possibility of blockage of the water leakage port 9. Through rotation, the solid waste on the inner wall of the drum 5 can be evenly distributed to prevent excessive accumulation in a single location and cause blockage.
[0026] See Figure 1 A funnel 6 is fixedly installed on the top of the drum 5, and the crushing roller 3 is located above the funnel 6, and the funnel 6 corresponds to the crushing roller 3.
[0027] The funnel 6 covers the crushing roller 3 and increases the inlet area of the drum 5 to prevent the garbage crushed by the crushing roller 3 from being scattered outside the drum 5.
[0028] See Figure 1 and Figure 3A fixed plate 11 is fixedly installed on the inner wall of the crushing device 1, and the outer wall of the support rod 7 is rotatably connected to the fixed plate 11. A servo motor 16 is fixedly installed on the inner bottom wall of the crushing device 1, and the driving end of the servo motor 16 is connected to the bottom end of the support rod 7.
[0029] The fixing plate 11 is used to support the support rod 7 and enable the support rod 7 to rotate, and the servo motor 16 is responsible for driving the support rod 7 to rotate.
[0030] See Figure 1 and Figure 3 A filter plate 10 is fixedly installed on the inner wall of the crushing device 1. The side of the filter plate 10 away from the crushing device 1 is fixedly connected to the outer wall of the fixed plate 11. The bottom end of the drum 5 is rotatably connected to the top of the filter plate 10. A gap is left between the filter plate 10 and the inner bottom wall of the crushing device 1.
[0031] The filter plate 10 supports the drum 5 and enables the drum 5 to rotate along the top of the filter plate 10. After the liquid flows out from the leaking port 9, it can pass through the pores of the filter plate 10 and fall to the bottom of the filter plate 10, and then the liquid can be discharged conveniently to avoid the liquid accumulating around the drum 5 and flowing back into the drum 5.
[0032] See Figure 1 The crushing device 1 is provided with a liquid outlet 14, and a liquid collecting box 4 is connected to one side of the crushing device 1. The liquid collecting box 4 is provided with a liquid inlet 15. The liquid outlet 14 corresponds to the liquid inlet 15. The liquid collecting box 4 is connected to the crushing device 1, and the liquid outlet 14 is located below the filter plate 10.
[0033] The liquid passes through the filter plate 10 and flows to the liquid outlet 14, and then flows into the liquid collection box 4 through the liquid outlet 14 and the liquid inlet 15. The liquid is collected by the liquid collection box 4 to avoid liquid accumulation in the crushing device 1, which is convenient for subsequent processing.
[0034] See Figure 1 and Figure 3 The inner bottom wall of the crushing device 1 is fixedly installed with an inclined plate 13, and the inclined plate 13 is located below the filter plate 10. The inner bottom wall of the crushing device 1 is fixedly installed with a baffle 12, and the baffle 12 is located between the fixed plate 11 and the filter plate 10.
[0035] The inclined plate 13 allows the liquid to flow directly to the position of the liquid outlet 14 along the inclined surface of the inclined plate 13 to avoid liquid residue. The baffle 12 blocks the liquid and the servo motor 16 to prevent the liquid from spilling to the position of the servo motor 16 and affecting the operation of the servo motor 16.
[0036] See Figure 1-Figure 2 A feed hopper 2 is fixedly installed on the inner wall of the crushing device 1, and the feed hopper 2 corresponds to the crushing roller 3.
[0037] The feed hopper 2 guides the garbage so that the garbage can slide directly onto the crushing roller 3, making it easier for the crushing roller 3 to directly crush the kitchen waste.
[0038] Working principle:
[0039] After being crushed by multiple crushing rollers 3, the kitchen waste falls into the drum 5. The liquid in the kitchen waste flows out through the drain hole 9, while the solid waste cannot pass through the drain hole 9. The aperture of the drain hole 9 is such that even if the kitchen waste is crushed, it cannot pass through the insertion rod 8 and flow out, thus achieving solid-liquid separation. However, a part of the crushed kitchen waste will block the drain hole 9. Therefore, the support rod 7 is driven to rotate. After the support rod 7 rotates, it drives the multiple insertion rods 8 to rotate together. The insertion rods 8 will continuously insert into the drain hole 9 during rotation, so the drain hole 9 can be dredged by the insertion rods 8.
[0040] After a row of rods 8 are inserted into the water leakage port 9, the rods 8 continue to rotate, pushing the water leakage port 9 to one side, and then the next group of rods 8 are inserted into the new water leakage port 9, causing the drum 5 and the water leakage port 9 to rotate together. Therefore, each water leakage port 9 can be cleaned, and the rotation of the drum 5 can reduce the possibility of blockage of the water leakage port 9. Through rotation, the solid waste on the inner wall of the drum 5 can be evenly distributed to prevent excessive accumulation in a single location and cause blockage.
