[0038] Example:

[0039] See also Figure 1-9 , an agricultural irrigation canal pollution-blocking gate, comprising a frame 1 and a gate plate 2 mounted on the frame 1, a filter plate 3 is fixedly mounted in the middle of the frame 1, the filter plate 3 can block pollutants on one side of the gate plate 2 to prevent the pollutants from flowing into the farmland, the filter plate 3 is located at the front end of the gate plate 2, two driving mechanisms are mounted on the frame 1, a salvage frame 4 is mounted on the frame 1, the driving mechanism drives the salvage frame 4 to rotate in the studio, and the pollutants accumulated at the front end of the filter plate 3 are salvaged when the salvage frame 4 rotates;

[0040] The salvage frame 4 includes a filter frame 5 and two salvage plates 6 rotatably mounted at the lower end of the filter frame 5, and a threaded groove 7 is formed on the inner wall of one end of the salvage plate 6;

[0041] Two guide grooves 8 are provided on the filter plate 3, and a first slide groove 9 is provided on the filter frame 5. A guide rod 10 is slidably installed inside the first slide groove 9. When the salvage frame 4 rotates, the guide rod 10 can continuously move along the direction of the guide groove 8. An extrusion rod 11 is fixedly installed on the guide rod 10. The raised portion on the outer wall of the extrusion rod 11 is in extrusion contact with the inner wall of the thread groove 7. When the extrusion rod 11 moves, the raised portion on the outer wall can squeeze the inner wall of the thread groove 7, thereby causing the salvage plate 6 to rotate.

[0042] Specifically, the driving mechanism includes a motor 12 installed on the frame 1, and a first reciprocating threaded rod 13 is fixedly installed at the output end of the motor 12. The driving mechanism also includes a first slider 14 slidably installed on the frame 1. The protrusion on the inner wall of the first slider 14 is in sliding contact with the inner wall of the groove on the first reciprocating threaded rod 13. When the motor 12 drives the first threaded rod to rotate, it can drive the first slider 14 to move continuously. A support rod 15 is rotatably installed on the first slider 14. When the first slider 14 moves, it can drive the support rod 15 to rotate. One end of the support rod 15 away from the first slider 14 is rotatably connected to the lower end of the filter frame 5. After rotating, the support rod 15 can squeeze the lower end of the filter frame 5, thereby rotating it.

[0043] Furthermore, the guide groove 8 includes two arc grooves 16 and two inclined grooves 17. The two ends of the two arc grooves 16 are connected by two inclined grooves 17. A magnet 18 is embedded on the inner wall of one of the arc grooves 16. The magnet 18 is magnetically connected to the guide rod 10. The set magnet 18 can enable the guide rod 10 to enter the upper arc groove 16 when rotating upward.

[0044] Furthermore, two limit grooves 19 are provided on the frame 1, and a limit block 20 is slidably installed inside the limit groove 19, and a connecting mechanism is installed on the limit block 20. A second slide groove 21 is provided on the inner wall of the filter frame 5, and an extrusion block 22 is provided inside the filter frame 5. The outer wall of the extrusion block 22 is slidably connected to the second slide groove 21 through a second slider 23. The limit block 20 pushes the extrusion block 22 through the connecting mechanism to extrude the pollutants in the filter frame 5.

[0045] It is worth mentioning that the connecting structure includes two fixed rods 24 fixedly mounted on the limit block 20. When the limit block 20 moves along the direction of the limit groove 19, the fixed rod 24 can be driven to move. A pushing rod 25 is rotatably connected to the fixed rod 24. The fixed rod 24 is elastically connected to the pushing rod 25 through a spring. After the fixed rod 24 moves, the pushing rod 25 can be squeezed by the spring. Two moving grooves 26 are provided at the upper end of the limit block 20. The lower end of the pushing rod 25 is located inside the moving groove 26 and is slidably connected thereto. The connecting mechanism also includes two pull ropes 27 that pass through the limit block 20. One end of the pull rope 27 passes through the limit block 20 and is fixedly connected to the outer wall of the filter frame 5. The other ends of the two pull ropes 27 are respectively fixedly connected to the outer walls of the two pushing rods 25. When the pushing rod 25 rotates, it can squeeze the inner wall of the moving groove 26 and move along the direction of the moving groove 26. At this time, the squeezing block 22 can release the squeezed pollutants after being pushed, so as to facilitate the compressed pollutants to separate from the filter frame 5.

[0046] In addition, a puncture mechanism is installed on the filter frame 5, and a driving mechanism is arranged on the filter frame 5 at a position relative to the puncture mechanism. When the filter frame 5 rotates, the driving mechanism punctures the pollutants through the puncture mechanism.

[0047] It is worth noting that the puncture mechanism includes a movable frame 28 slidably mounted on the filter frame 5, and a plurality of spikes 29 are fixedly mounted on the movable frame 28. The movable frame 28 can drive the spikes 29 to move after moving, and the movement of the spikes 29 can puncture the plastic bag or plastic bottle to prevent the plastic bag or plastic bottle from containing water being thrown out with the plastic bag or plastic bottle. The puncture mechanism also includes a detachment plate 37, and the detachment plate 37 is elastically connected to the movable frame 28 by an elastic member.

[0048] In addition, the driving mechanism includes a second reciprocating threaded rod 30 rotatably connected to the filter frame 5, the protrusion on the movable frame 28 is in sliding contact with the inner wall of the groove on the second reciprocating threaded rod 30, and the second reciprocating threaded rod 30 can drive the movable frame 28 to move when rotating. The second reciprocating threaded rod 30 is fixedly connected to a gear 31 at one end close to the filter plate 3. The driving mechanism also includes two driving grooves 32 provided on the filter plate 3, and a plurality of meshing teeth 33 are provided on the inner wall of the driving groove 32. The gear 31 meshes with the meshing teeth 33 for transmission. When the position of the gear 31 is relative to the position of the meshing teeth 33, the gear 31 can rotate as the filter frame 5 continues to rotate.

[0049] Among them, one side of the upper end of the filter frame 5 is an inclined structure, and a cover plate 34 is rotatably installed on the upper end of the filter frame 5 close to the inclined side. When the filter frame 5 rotates to the uppermost end and stops rotating upward, the cover plate 34 will open under inertia, and the pollutants compressed in the filter frame 5 will be thrown out under inertia.

[0050] On the basis of the above scheme, a plurality of protrusions 35 are provided on the inner wall of the arc groove 16, and the outer wall of the guide rod 10 is in frictional contact with the outer wall of the protrusion 35. When the guide rod 10 contacts the protrusion 35, the guide rod 10 can continuously shake, and the guide rod 10 can continuously drive the extrusion rod 11 to continuously shake. Two shaking plates 36 are slidably installed on the salvage plate 6, and the shaking plate 36 is elastically connected to the salvage plate 6 through elastic parts. Under the action of the threaded groove 7, the salvage plate 6 is continuously shaken. At this time, under the action of the elastic parts on the shaking plate 36, the shaking plate 36 will shake as the salvage plate 6 continuously shakes, so that the water between the pollutants can be quickly shaken out of the filter frame 5, and the two shaking plates 36 are squeezed and contacted at the ends close to each other.

[0051] Working principle: when the device is needed to work, the motor 12 is used to drive the first reciprocating threaded rod 13 to rotate. When the first reciprocating threaded rod 13 rotates, it can drive the first slider 14 to continuously reciprocate along the direction of the first reciprocating threaded rod 13. When the first slider 14 moves, it can drive the support rod 15 to rotate. After the support rod 15 rotates, it can squeeze the lower end of the filter frame 5 to make it rotate. When the filter frame 5 rotates, due to the limited distance between the limit block 20 and the extrusion block 22, when the filter frame 5 rotates, the limit block 20 will rise along the direction of the limit groove 19. When the limit block 20 rises and the filter frame 5 rotates, the extrusion block 22 will move along the direction of the filter frame 5 under the action of the connecting structure. When the extrusion block 22 moves, the dirt in the filter frame 5 can be squeezed out. The dye is pushed to the side away from the frame 1. In this process, when the extrusion block 22 moves to a certain position relative to the filter frame 5, the pull rope 27 will be tightened. After the pull rope 27 is tightened, the push rod 25 can be fixed, so that the extrusion block 22 is fixed relative to the filter frame 5, and as the filter frame 5 continues to rotate, the limit block 20 will continue to move. At this time, the limit block 20 continues to move, which will cause the fixed rod 24 to continue to move. When the fixed rod 24 continues to move, the middle part of the push rod 25 is pulled by the pull rope 27. Therefore, when the fixed rod 24 continues to move, it will drive the push rod 25 to rotate along the tightening point of the pull rope 27. After the push rod 25 rotates, it can squeeze the inner wall of the moving groove 26 and move along the inner wall of the moving groove 26. At this time, the extrusion block 22 can move relative to the filter frame 5. The initial position moves a distance, wherein, during the rotation of the filter frame 5, the second reciprocating threaded rod 30 and the gear 31 can be driven to perform an orbital motion, and when the gear 31 rotates to the meshing tooth 33, it can mesh with the meshing tooth 33, and then as the filter frame 5 continues to rotate, the meshing tooth 33 can drive the gear 31 to rotate, and when the gear 31 rotates, it can drive the second reciprocating threaded rod 30 to rotate, and the second reciprocating threaded rod 30 can drive the moving frame 28 to move, and after the moving frame 28 moves, it can drive the spike 29 to move, and the movement of the spike 29 can puncture the pollutants in the filter frame 5. In this process, the separation plate 37 will be squeezed by the pollutants in the filter frame 5, thereby moving relative to the moving frame 28, and squeezing the separation plate 37 and the moving frame 28. The elastic member destroys the plastic bag or plastic bottle in the pollutants to prevent the plastic bag or plastic bottle in the pollutants from being filled with a large amount of water, and after the plastic bag or plastic bottle is destroyed, the movable frame 28 will move to the initial direction, at this time, under the action of the elastic member on the separation plate 37, the plastic bag or plastic bottle on the spike 29 can be pushed down to separate it from the spike 29 to prevent the plastic bag or plastic bottle from being stuck outside the spike 29, and then as the filter frame 5 continues to rotate, when the filter frame 5 rotates to the uppermost end and stops rotating upward, the cover plate 34 will open under inertia, and the compressed pollutants in the filter frame 5 will be thrown out under inertia, so that the pollutants fall to the surrounding land, which is convenient for the staff to clean up, and then when the filter frame 5 rotates to the initial position,The guide rod 10 will pass through the upper inclined groove 17 and enter the lower arc groove 16, so that the guide rod 10 moves inside the first slide groove 9. After the guide rod 10 moves, it can drive the squeezing rod 11 to move. When the squeezing rod 11 moves, the protrusion on the outer wall will squeeze the inner wall of the threaded groove 7, so that the salvage plate 6 rotates. After the salvage plate 6 rotates, the lower end of the filter frame 5 can be opened. Then, as the filter frame 5 continues to rotate to the initial position, when the guide rod 10 moves to the lower inclined groove 17, the guide rod 10 can drive the squeezing rod 11 to move to the initial position, so that the salvage plate 6 rotates again so that the lower side of the filter frame 5 is closed. During the closing process of the salvage plate 6, the pollutants directly below the filter frame 5 can be salvaged into the filter frame 5. The protrusion 35 provided can make the guide rod 10 shake continuously when the guide rod 10 contacts it, and the guide rod 10 can continuously drive the extrusion rod 11 to shake continuously, and then the salvage plate 6 can shake continuously under the action of the thread groove 7. At this time, under the action of the elastic member on the shaking plate 36, the shaking plate 36 will shake with the continuous shaking of the salvage plate 6, so that the water between the pollutants can be quickly shaken out of the filter frame 5. The magnet 18 provided can make the guide rod 10 enter the upper arc groove 16 when it rotates upward.

[0052] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
