[0017] S1: When using the device to separate wet and dry food waste, first pour the food waste into the device housing from the feed pipe, then start the motor to drive the first rotating shaft to rotate, the rotation of the first rotating shaft drives the rotation of the conveying screw, and the food waste is conveyed to one side of the discharge cover by the conveying screw. The food waste is squeezed during the movement in the separation cylinder, and the water inside the waste is filtered out through the first filter hole and the second filter hole, and finally discharged from the liquid outlet hole;

[0018] S2: At the same time, the rotation of the first rotating shaft drives the rotation of the second gear, the rotation of the second gear drives the rotation of the first gear, the rotation of the first gear drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the rotating plate, the rotation of the rotating plate drives the rotation of the sliding rod, during the rotation of the sliding rod, it slides in the inner wall of the connecting plate and drives the connecting plate to swing around the first rotating shaft, the swinging of the connecting plate drives the rotating ring to rotate inside the device shell, the rotation of the rotating ring is connected through the fixed rod and the second connecting shaft to drive the moving rod to swing under the separation cylinder, the swinging of the moving rod drives the protrusion to contact the bottom end of the separation cylinder, and the elastic potential energy of the tension spring causes the protrusion to move up and down to knock on the outer wall of the bottom end of the separation cylinder, which helps to discharge the moisture inside the kitchen waste in the separation cylinder;

[0019] S3: When the moving rod moves on the outer wall of the bottom end of the separation cylinder, the protrusion contacts the bottom end of the connecting rod or the inserting rod, so that the inserting rod moves in the inner wall of the first filter hole, which helps to push the impurities and fibers in the inner wall of the first filter hole upward;

[0020] S4: Finally, turn the hand wheel to move the discharge cover to the side away from the installation side plate to discharge the garbage.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention sets a knocking component. When using the device to separate wet and dry food waste, first pour the food waste into the device housing from the feed pipe, then start the motor to drive the first rotating shaft to rotate, the rotation of the first rotating shaft drives the rotation of the conveying screw, and the food waste is conveyed to one side of the discharge cover by the conveying screw. The food waste is squeezed during the movement in the separation cylinder, and the moisture inside the waste is filtered out through the first filter hole and the second filter hole, and finally discharged from the liquid outlet. At the same time, the rotation of the first rotating shaft drives the rotation of the second gear, the rotation of the second gear drives the rotation of the first gear, the rotation of the first gear drives the rotation of the second rotating shaft, and the second rotating shaft drives the rotation of the second gear. The rotation of the shaft drives the rotation of the rotating plate, and the rotation of the rotating plate drives the rotation of the sliding rod. During the rotation of the sliding rod, it slides in the inner wall of the connecting plate and drives the connecting plate to swing around the first rotating shaft. The swing of the connecting plate drives the rotating ring to rotate inside the device shell. The rotation of the rotating ring drives the moving rod to swing under the separation cylinder through the fixed rod and the second connecting shaft. The swing of the moving rod drives the protrusion to contact the bottom end of the separation cylinder. Under the elastic potential energy of the tension spring, the protrusion moves up and down to hit the outer wall of the bottom end of the separation cylinder, which helps to discharge moisture inside the food waste in the separation cylinder and reduce the clogging of the filter, thereby improving the dry and wet separation effect and efficiency of the food waste.

[0023] 2. The present invention provides a dredging component. When the movable rod moves on the outer wall of the bottom end of the separation cylinder, the protrusion contacts the bottom end of the connecting rod or the insertion rod, so that the insertion rod moves in the inner wall of the first filter hole, which helps to push impurities and fibers in the inner wall of the first filter hole upward, reducing the risk of clogging the inner wall of the first filter hole, thereby ensuring the dry-wet separation processing efficiency of the device.

[0024] 3. The present invention sets the top end of the insertion rod to be conical, so that when the insertion rod is inserted into the first filter hole, it can not only disperse the force more evenly, reduce the wear and damage to the edge of the inner wall of the first filter hole, and extend its service life, but also make it easier for the insertion rod to penetrate into the first filter hole for cleaning, thereby ensuring the patency of the separation cylinder.

[0036] One end of the moving rod 16 is fixedly connected to the second connecting shaft 21, and a fixed rod 20 is installed on the outer wall of the second connecting shaft 21. A rotating ring 19 is fixedly installed on the end of the fixed rod 20 away from the second connecting shaft 21. The rotating ring 19 is rotatably installed inside the device housing 1, and a connecting plate 22 is fixedly connected to the side wall of the rotating ring 19. The top end of the connecting plate 22 is rotatably installed on the outer wall of the first rotating shaft 13. A sliding rod 23 is slidably connected to the inner wall of the connecting plate 22. A rotating plate 24 is fixedly installed on one end of the sliding rod 23. The inside of the rotating plate 24 is fixedly connected to the second rotating shaft 25. A first gear 26 is fixedly installed on the outer wall of the second rotating shaft 25. The top end of the first gear 26 is meshingly connected to the second gear 27, and the second gear 27 is fixedly installed on the outer wall of the first rotating shaft 13.

[0037] When the device is used to perform dry-wet separation of food waste, the food waste is first poured into the device housing 1 from the feed pipe 2, and then the motor 12 is started to drive the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 drives the rotation of the conveying screw 14, and the food waste is conveyed to one side of the discharge cover 8 through the conveying screw 14. The food waste is squeezed during the movement in the separation cylinder 3, and the water inside the waste is filtered out through the first filter hole 4 and the second filter hole 5, and finally discharged from the liquid outlet 11;

[0038] At the same time, the rotation of the first rotating shaft 13 drives the rotation of the second gear 27, the rotation of the second gear 27 drives the rotation of the first gear 26, the rotation of the first gear 26 drives the rotation of the second rotating shaft 25, the rotation of the second rotating shaft 25 drives the rotation of the rotating plate 24, the rotation of the rotating plate 24 drives the rotation of the sliding rod 23, during the rotation of the sliding rod 23, the sliding rod 23 slides in the inner wall of the connecting plate 22 and drives the connecting plate 22 to swing around the first rotating shaft 13, the swing of the connecting plate 22 drives the rotating ring 19 to rotate inside the device housing 1, the rotation of the rotating ring 19 is connected through the fixed rod 20 and the second connecting shaft 21 to drive the moving rod 16 to swing below the separation cylinder 3, the swing of the moving rod 16 drives the protrusion 28 to contact the bottom end of the separation cylinder 3, and the elastic potential energy of the tension spring 30 causes the protrusion 28 to move up and down to knock the outer wall of the bottom end of the separation cylinder 3, which is helpful to discharge the moisture inside the food waste in the separation cylinder 3, reduce the clogging of the filter, thereby improving the dry and wet separation effect and efficiency of the food waste;

[0039] When discharging garbage, the hand wheel 9 is turned to move the discharge cover 8 to the side away from the mounting side plate 6, and the garbage inside the separation cylinder 3 is discharged.

[0040] like Figure 4 As shown, the inner wall diameter of the second filter hole 5 is smaller than the inner wall diameter of the first filter hole 4 .

[0041] When the kitchen waste is separated into dry and wet parts, the water in the waste is first discharged from the first filter hole 4 and then from the second filter hole 5. The first filter hole 4 and the second filter hole 5 have different inner wall diameters, which can more effectively retain water and fine particles, making the dry and wet separation more thorough.

[0042] like Figure 3 and Figure 4 As shown, the inner wall of the separation cylinder 3 away from the conveying screw 14 is configured to be a truncated cone.

[0043] The inner wall diameter of the separation cylinder 3 on the side away from the conveying screw 14 gradually decreases;

[0044] When the food waste inside the separation cylinder 3 moves toward one side of the discharge cover 8 after filtering water, the reduction in the inner wall diameter helps to further discharge the water in the food waste, thereby improving the dry-wet separation treatment effect.

[0045] like Figure 4 and Figure 5 As shown, the clearing assembly includes an insert rod 31 arranged inside the first filter hole 4, a connecting rod 32 is fixedly installed on the outer wall of the insert rod 31, the connecting rod 32 is arranged below the separation cylinder 3, a slider 33 is fixedly connected to the top of the connecting rod 32, the slider 33 is slidably installed inside the separation cylinder 3, and a spring 34 is arranged on the top of the slider 33.

[0046] When the movable rod 16 moves on the outer wall at the bottom end of the separation cylinder 3, the protrusion 28 contacts the bottom end of the connecting rod 32 or the insertion rod 31, so that the insertion rod 31 moves in the inner wall of the first filter hole 4, which helps to push the impurities and fibers in the inner wall of the first filter hole 4 upward, reducing the risk of clogging of the inner wall of the first filter hole 4, thereby ensuring the processing efficiency of the dry-wet separation device.

[0047] like Figure 5 As shown, the top end of the insertion rod 31 is configured to be conical.

[0048] When the insertion rod 31 is inserted into the first filter hole 4, it can not only disperse the force more evenly, reduce the wear and damage to the inner wall edge of the first filter hole 4, and extend its service life, but also make it easier for the insertion rod 31 to penetrate into the first filter hole 4 for cleaning, thereby ensuring the patency of the separation cylinder 3.

[0049] like Figure 4 and Figure 5 As shown, a first connecting shaft 15 is fixedly mounted on one side of the separation cylinder 3 . The first connecting shafts 15 are evenly distributed in a ring array and are embedded in the interior of the device housing 1 .

[0050] When maintaining the separation cylinder 3, firstly, the bolts 7 are turned to remove several bolts 7, and then the mounting side plate 6 is moved away from the device housing 1, and finally the separation cylinder 3 is taken out. When the separation cylinder 3 moves outward, the first connecting shaft 15 is driven to slide out from the inside of the device housing 1, so as to facilitate maintenance;

[0051] Similarly, when installing the separation cylinder 3 , the first connecting shaft 15 is installed by embedding it into the device housing 1 .

[0052] like Figure 2 and Figure 6 As shown, one end of the moving rod 16 is fixedly connected to a connecting ring 17 , and the connecting ring 17 is rotatably mounted inside the mounting side plate 6 .

[0053] like Figure 7 As shown, the second connecting shaft 21 is slidably connected to the fixing rod 20 .

[0054] When the mounting side plate 6 is removed, the scraper ring 18 moves to drive the second connecting shaft 21 to slide out from the inside of the fixing rod 20, separating them;

[0055] Similarly, during installation, the second connecting shaft 21 is embedded in the interior of the fixing rod 20 for connection.

[0056] like Figure 2 and Figure 6 As shown, a scraper ring 18 is fixedly mounted on one end of the moving rod 16 away from the connecting ring 17 , and the scraper ring 18 is slidably mounted on the outer wall of the separation cylinder 3 .

[0057] When maintaining the separation cylinder 3, the movement of the mounting side plate 6 drives the movement of the connecting ring 17, the movement of the connecting ring 17 drives the movement of the moving rod 16, and the movement of the moving rod 16 drives the movement of the scraper ring 18, so that the scraper ring 18 slides on the outer wall of the separation cylinder 3, which helps to scrape off the impurities on the surface of the separation cylinder 3 and facilitates the maintenance of the separation cylinder 3.

The food waste is squeezed during the movement in the separation cylinder 3, and the water inside the waste is filtered out through the first filter hole 4 and the second filter hole 5, and finally discharged from the liquid outlet 11;

[0060] S2: At the same time, the rotation of the first rotating shaft 13 drives the rotation of the second gear 27, the rotation of the second gear 27 drives the rotation of the first gear 26, the rotation of the first gear 26 drives the rotation of the second rotating shaft 25, the rotation of the second rotating shaft 25 drives the rotation of the rotating plate 24, the rotation of the rotating plate 24 drives the rotation of the sliding rod 23, during the rotation of the sliding rod 23, it slides in the inner wall of the connecting plate 22 and drives the connecting plate 22 to swing around the first rotating shaft 13, the swing of the connecting plate 22 drives the rotating ring 19 to rotate inside the device housing 1, the rotation of the rotating ring 19 is connected through the fixed rod 20 and the second connecting shaft 21 to drive the moving rod 16 to swing below the separation cylinder 3, the swing of the moving rod 16 drives the protrusion 28 to contact the bottom end of the separation cylinder 3, and under the elastic potential energy of the tension spring 30, the protrusion 28 moves up and down to knock the outer wall of the bottom end of the separation cylinder 3, which helps to discharge the moisture inside the kitchen garbage in the separation cylinder 3;

[0061] S3: When the moving rod 16 moves on the outer wall of the bottom end of the separation cylinder 3, the protrusion 28 contacts the bottom end of the connecting rod 32 or the inserting rod 31, so that the inserting rod 31 moves in the inner wall of the first filter hole 4, which helps to push the impurities and fibers in the inner wall of the first filter hole 4 upward;

[0062] S4: Finally, the hand wheel 9 is turned to move the discharge cover 8 to the side away from the mounting side plate 6 to discharge the garbage.
