[0033] After the vegetables are washed by the vegetable washing machine 1 using the cleaning nozzle 101 and the conveyor belt 103, the washed sewage can be discharged through the drain pipe 2. When discharging the sewage, the filter 3 provided inside the drain pipe 2 is used to prevent the vegetable leaves from flowing out. When the vegetable leaves accumulate on the surface of the filter 3, the movable plate 10 can be pulled with the help of the scraper 11 to push the vegetable leaves into the storage net 7, so that the filter 3 can be used continuously without the need to disassemble the filter 3.

[0034] Example 2

[0035] On the basis of Example 1, in order to facilitate the filtering of vegetable leaves and larger impurities in sewage, a filter screen 3 and an auxiliary filter screen 5 are provided. A guide frame 13 is provided at the bottom of the drain pipe 2. The guide frame 13 is fixed to the bottom of the drain pipe 2 with a limiting bolt. Two groups of movable grooves 8 are provided. The two groups of movable grooves 8 are symmetrically distributed up and down about the inside of the drain pipe 2. One group of movable grooves 8 runs through the drain pipe 2. The filter screen 3 is fixedly connected to the drain pipe 2 with a positioning bolt. A rotating groove 18 is provided on the inner surface of the drain pipe 2. A rubber strip 19 is provided at the bottom of the auxiliary filter screen 5. The bottom of the rubber strip 19 contacts the surface of the rotating groove 18. A positioning groove 20 is provided on the inner surface of the drain pipe 2. The positioning groove 20 is a circular plate-shaped structure. An auxiliary plate 26 is provided on the side of the auxiliary filter screen 5. A through hole is provided on the surface of the auxiliary plate 26. A limiting rod 21 is inserted into the through hole. One end of the limiting rod 21 is inserted into the positioning groove 20. The auxiliary plate 26 is a square plate-shaped structure.

[0036] During use, when the drain pipe 2 is used to discharge the sewage from washing vegetables, the filter screen 3 and the auxiliary filter screen 5 provided in the drain pipe 2 can be used to filter the washing sewage. When a large number of larger impurities occur inside the drain pipe 2 and cause blockage, the limit rod 21 can be pulled upward to disengage one end of the limit rod 21 from the positioning groove 20, so that the auxiliary filter screen 5 can be rotated with the help of the hinge 4, so that the filtration of the inside of the drain pipe 2 can be lost through the rotation angle of the auxiliary filter screen 5, and then the larger blockages inside the drain pipe 2 can be conveniently cleaned out. The opening of the rotating groove 18 can facilitate the auxiliary filter screen 5 to avoid conflict with the bottom of the drain pipe 2 when rotating the auxiliary filter screen 5. When the auxiliary filter screen 5 does not need to be opened, it is only necessary to insert one end of the limit rod 21 into the positioning groove 20 to fix the auxiliary filter screen 5.

[0037] In order to facilitate the cleaning of the dirt and large vegetable leaves attached to the surface of the filter screen 3 and the auxiliary filter screen 5, a movable plate 10 is provided, the support rod 9 is fixedly connected to the end face of the movable groove 8, one end of the return spring 12 is fixedly connected to the end face of the movable groove 8, and the other end of the return spring 12 is fixedly connected to the side face of the movable plate 10. A placement groove 14 is provided on the side face of the movable groove 8 that passes through the upper surface of the drain pipe 2. The placement groove 14 is a square plate-shaped structure, and the scraper 11 is fixedly connected to the side face of the movable plate 10. The scraper 11 is a square plate-shaped structure as a whole. The scraper 11 contacts the surface of the filter screen 3 and the auxiliary filter screen 5. The scraper 11 is made of rubber. The thickness of the scraper 11 is greater than the thickness of the movable plate 10, and the long side of the scraper 11 is smaller than the long side of the discharge port 6.

[0038] When in use, the movable plate 10 can be directly pulled so that the scraper 11 set on the side of the movable plate 10 can clean the surface of the filter screen 3 and the auxiliary filter screen 5. Then the scraper 11 can be inserted into the discharge port 6 to send the soil or vegetable leaves from the discharge port 6 into the storage net 7 for storage. The setting of the reset spring 12 can facilitate the automatic reset of the movable plate 10 with the help of the elastic force of the reset spring 12 after pulling the movable plate 10, and also prevent the movable plate 10 from being displaced arbitrarily in the drain pipe 2.

[0039] Example 3

[0040] On the basis of the second embodiment, in order to facilitate the collection of cleaned vegetable leaves, a storage net 7 is provided, a mounting plate 22 is provided on the side of the drain pipe 2, and a positioning slot 23 is opened on the surface of the mounting plate 22. Two groups of mounting plates 22 are provided, and the two groups of mounting plates 22 are symmetrically distributed about the discharge port 6. The length of the long side of the positioning slot 23 is less than the length of the long side of the mounting plate 22. The mounting plate 22 is fixed to the side of the drain pipe 2 by means of a limiting bolt. A fixing frame 24 is provided on the end face of the storage net 7. The fixing frame 24 is inserted into the positioning slot 23. A damping pad 25 is provided in the positioning slot 23. The damping pad 25 has an "L"-shaped plate structure and is glued and fixed in the positioning slot 23.

[0041] When in use, first insert the fixing frame 24 into the positioning slot 23, and then use the storage net 7 to block the side of the discharge port 6, so that the vegetable leaves and soil pushed out by the scraper 11 can enter the storage net 7. The setting of the damping pad 25 can increase the friction between the fixing frame 24 and the positioning slot 23 to improve the installation stability of the storage net 7.

[0042] In order to facilitate covering the movable groove 8, a corrugated plate 17 is provided, a traction rod 15 is provided on the end face of the placement groove 14, and a folding plate 16 is provided on the surface of the traction rod 15. The placement groove 14 is provided with two groups, and the two groups of placement grooves 14 are symmetrically distributed about the movable groove 8. A corrugated plate 17 is provided on the side of the folding plate 16. The corrugated plate 17 covers the top of the movable groove 8. One end of the corrugated plate 17 is fixedly connected to the end face of the movable groove 8, and the other end of the corrugated plate 17 is fixedly connected to the side face of the movable plate 10. The movable plate 10 has a square plate structure as a whole. The movable plate 10 is slidably connected to the support rod 9, and the corrugated plate 17 and the folding plate 16 can both be folded and compressed;

[0043] When in use, the movable groove 8 passing through the drain pipe 2 can be covered by the corrugated plate 17. When the movable plate 10 is pulled, the folding plate 16 and the corrugated plate 17 can be pushed to be compressed and folded to prevent the corrugated plate 17 from affecting the displacement of the movable plate 10. The setting of the traction rod 15 can guide the compression of the corrugated plate 17 to prevent the corrugated plate 17 from detaching from the movable groove 8.

[0044] In actual use, after the vegetables are washed by the vegetable washing machine 1 using the cleaning nozzle 101 and the conveyor belt 103, the washed sewage can be discharged through the drain pipe 2. When discharging the sewage, the filter 3 provided inside the drain pipe 2 is used to prevent the vegetable leaves from flowing out. When the vegetable leaves accumulate on the surface of the filter 3, the movable plate 10 can be pulled to push the vegetable leaves into the receiving net 7 with the help of the scraper 11, so that the filter 3 can be used continuously without the need to disassemble the filter 3. When the sewage from washing vegetables is discharged by the drain pipe 2, the filter 3 and the auxiliary filter 5 provided in the drain pipe 2 can be used to filter the sewage. When a large number of larger impurities occur inside the drain pipe 2 and cause blockage, the limiting rod 21 can be pulled upward to disengage one end of the limiting rod 21 from the positioning groove 20, so that the auxiliary filter screen 5 can be rotated with the help of the hinge 4, so that the filtering of the inside of the drain pipe 2 can be lost through the rotation angle of the auxiliary filter screen 5, and then the larger blockages inside the drain pipe 2 can be conveniently cleaned out. The opening of the rotating groove 18 can facilitate the auxiliary filter screen 5 to rotate without conflict with the bottom of the drain pipe 2. When the auxiliary filter screen 5 does not need to be opened, it is only necessary to insert one end of the limiting rod 21 into the positioning groove 20 to fix the auxiliary filter screen 5.
