[0001] The invention relates to the field of trash rack cleaning, in particular to a trash rack self-cleaning device for a high-standard farmland irrigation channel. Background Art

[0002] High-standard farmland has flat land, concentrated and contiguous areas, complete facilities, supporting farmland, fertile soil, good ecology, strong disaster resistance, and the ability to ensure high and stable yields in drought and flood, which is compatible with modern agricultural production and management methods. It is designated as permanent basic farmland.

[0003] High-standard farmland is mostly irrigated using artificially dug irrigation ditches. In order to prevent larger impurities from entering the farmland through the irrigation ditches, trash racks are installed inside the ditches.

[0004] However, most of the existing trash racks are directly made of metal materials. Since they are not equipped with a self-cleaning structure, they need to be cleaned manually on a regular basis to avoid the problem of clogging of the trash rack and affecting irrigation. Even if an electric cleaning mechanism is provided to automatically clean the trash rack, it consumes electricity when it is driven by a motor to clean it. In order to avoid unnecessary electricity consumption, the motor is not driven all the time to clean it. The trash rack may still be clogged and not cleaned. Therefore, it is necessary to propose a high-standard trash rack self-cleaning device for farmland irrigation channels to clean the trash rack regularly. Summary of the invention

[0005] In view of the prior art, an electric cleaning mechanism is provided to automatically clean the trash rack.

[0007] A first stroke groove is formed on the outer wall of the side rod, a stroke bolt is inserted into the first stroke groove, one end of the stroke bolt passes through the first stroke groove and is threadedly connected to the scraper, both ends of the scraper are fixedly connected with a stroke rod, and the plate walls of the two side plates are formed with a second stroke groove corresponding to the stroke rod, the second stroke groove passes through the side plate and is inclined upward;

[0008] The non-return travel components are provided with two, and the two non-return travel components are symmetrically arranged on the plate walls on the inner sides of the two side plates.

[0009] Specifically, the non-return travel assembly includes an outer shell and a fixed rod, the outer shell is fixedly connected to the grille through a fixedly connected connecting rod, a through slot is opened inside the outer shell, the fixed rod is arranged at one end of the outer shell away from the connecting rod, the fixed rod is fixedly connected to the plate wall of the side plate, and the other end of the fixed rod is fixedly connected to the non-return rod, the other end of the non-return rod extends to the inside of the through slot and is fixedly connected to a non-return cone, the non-return cone is slidably connected to the inside of the through slot, the inner top and inner bottom of the through slot near one end of the connecting rod are both provided with symmetrically arranged travel lock slots, the inside of the travel lock slots are both slidably plugged with wedge-shaped locking blocks, and the ends of the two wedge-shaped locking blocks away from the non-return cone are fixedly connected to the limiting rod, the limiting rod is slidably plugged with the outer shell, and the rod wall of the limiting rod is sleeved with a first spring;

[0010] A fixing ring is fixedly sleeved on the rod wall of the check rod close to one end of the fixed rod, a reset cone is sleeved on the rod wall of the check rod located between the fixed ring and the check cone, and a second spring is arranged between the reset cone and the fixed ring, and two ends of the second spring are fixedly connected to the reset cone and the fixed ring respectively.

[0011] Specifically, a fixed sleeve is movably sleeved on the outer wall of the second spring, a sliding sleeve is slidably sleeved on the outer wall of the fixed sleeve, and the fixed sleeve and the sliding sleeve are fixedly connected to the fixed ring and the reset cone respectively.

[0012] Specifically, a limiting slider is fixedly connected to the outer wall of the side rod, a limiting slot matching the limiting slider is provided on the inner wall of the side plate, and the limiting slider is slidably connected inside the limiting slot.

[0013] Specifically, the limiting sliding groove does not penetrate the side plate.

[0016] Specifically, the scraper frame is provided with adapting grooves which are adapted to the size and quantity of the hanging hooks.

[0017] Beneficial effects of the present invention:

[0018] The trash rack self-cleaning device for a high-standard farmland irrigation channel of the present invention symmetrically arranges side rods on both sides of the grille. When the through holes on the grille are blocked by impurities and the normal water diversion irrigation of the grille is affected, the grille is moved by the impact force of the water flow. When the grille moves, it can drive the slidably connected scraper to move along the second stroke groove inclined upward. The scraper can scrape off the impurities on the grille during the movement, thereby avoiding the problem of the grille being blocked by impurities and affecting normal irrigation. It relies on the impact force of the water flow on the grille to drive the scraper to clean, which can effectively solve the problem of untimely cleaning.

[0019] In addition, the check stroke assembly provided can effectively store force for the grille to prevent return. When the grille moves a certain distance and its movement is not enough to drive the scraper to move the full distance upward, the connecting rod can drive the wedge-shaped locking block inside the outer shell to collide with the check cone, thereby preventing the grille from resetting. As impurities are continuously filtered out of the grille, the grille can move again, not only allowing the scraper to move to the top, but also allowing the wedge-shaped locking block to move to the reset cone and drive the reset cone to move in the direction of the check cone. At this time, the wedge-shaped locking block can be reset along the outer walls of the reset cone and the check cone, and the grille can be reset under the elastic force of the arc leaf spring, so that the scraper can complete a complete cleaning stroke and reset.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1-Figure 9 As shown, a high-standard trash rack self-cleaning device for farmland irrigation channels of the present invention comprises a side plate 1, a grille 3, a scraper 11 and a non-return travel assembly 16, two side plates 1 are symmetrically arranged, the two side plates 1 are respectively arranged at both ends of the grille 3, and both ends of the grille 3 are fixedly connected with side rods 4, the scraper 11 is slidably connected to one side of the grille 3, and the adjacent sides of the two side plates 1 are both installed with connecting blocks 8 through mounting bolts 9, and the top of the connecting block 8 is fixedly connected with an arc leaf spring 7, and the other end of the arc leaf spring 7 is in contact with the side rod 4;

[0033] A first travel groove 10 is formed on the outer wall of the side rod 4, and a travel bolt 12 is inserted into the first travel groove 10. The travel bolt 12 passes through one end of the first travel groove 10 and is threadedly connected to the scraper 11. Both ends of the scraper 11 are fixedly connected with a travel rod 13, and the plate walls of the two side plates 1 are formed with a second travel groove 14 corresponding to the travel rod 13. The second travel groove 14 passes through the side plate 1 and is tilted upward.

[0034] Two non-return travel components 16 are provided, and the two non-return travel components 16 are symmetrically arranged on the plate walls on the inner sides of the two side plates 1 .

[0035] Specifically, the non-return travel assembly 16 includes an outer shell 161 and a fixed rod 168. The outer shell 161 is fixedly connected to the grille 3 through a fixedly connected connecting rod 162. A through slot 163 is provided inside the outer shell 161. The fixed rod 168 is arranged at one end of the outer shell 161 away from the connecting rod 162. The fixed rod 168 is fixedly connected to the plate wall of the side plate 1, and the other end of the fixed rod 168 is fixedly connected to a non-return rod 169. The other end of the non-return rod 169 extends to the inside of the through slot 163 and is fixedly connected to the plate wall of the side plate 1. A check cone 1610 is provided, and the check cone 1610 is slidably connected to the inside of the through groove 163. The inner top and inner bottom of the through groove 163 near one end of the connecting rod 162 are both provided with symmetrically arranged travel lock grooves 164, and wedge-shaped locking blocks 165 are slidably inserted in the travel lock grooves 164, and the ends of the two wedge-shaped locking blocks 165 away from the check cone 1610 are fixedly connected to the limiting rod 166, and the limiting rod 166 is slidably inserted with the outer shell 161, and the rod wall of the limiting rod 166 is sleeved with a first spring 167;

[0036] A fixing ring 1611 is fixedly sleeved on the rod wall of the check rod 169 near one end of the fixed rod 168, and a reset cone 1615 is sleeved on the rod wall of the check rod 169 located between the fixed ring 1611 and the check cone 1610, and a second spring 1613 is arranged between the reset cone 1615 and the fixing ring 1611, and the two ends of the second spring 1613 are fixedly connected to the reset cone 1615 and the fixing ring 1611 respectively, and the two ends of the second spring 1613 are welded and fixed to the reset cone 1615 and the fixing ring 1611 respectively by welding.

[0037] Specifically, a fixed sleeve 1612 is movably connected to the outer wall of the second spring 1613, and a sliding sleeve 1614 is slidably connected to the outer wall of the fixed sleeve 1612. The fixed sleeve 1612 and the sliding sleeve 1614 are fixedly connected to the fixed ring 1611 and the reset cone 1615 respectively. The arrangement of the sliding sleeve 1614 and the fixed sleeve 1612 can effectively prevent impurities from adhering to the second spring 1613 and affecting the normal use of the second spring 1613.

[0038] Specifically, a limiting slider 5 is fixedly connected to the outer wall of the side rod 4, and a limiting groove 6 adapted to the limiting slider 5 is opened on the inner wall of the side panel 1. The limiting slider 5 is slidably connected inside the limiting groove 6. When the limiting slider 5 slides inside the limiting groove 6, the connection between the side rod 4 and the side panel 1 can be effectively made more stable.

[0039] Specifically, the limiting slide groove 6 does not penetrate the side plate 1, which can effectively prevent the travel rod 13 from sliding into the limiting slide groove 6 and affecting the normal use of the device.

[0040] Specifically, adjacent sides of the two side panels 1 are fixedly connected with a connecting frame 2, and the connecting frame 2 can connect the two side panels 1, so that the device is more stable after installation.

[0041] Specifically, the top of the grille 3 is installed with a collection mesh frame 15 through a hanging hook 151, and the hanging hook 151 is fixedly connected to the top of the collection mesh frame 15. The hanging hook 151 is welded to the collection mesh frame 15 by welding, and the collection mesh frame 15 can collect impurities.

[0042] Specifically, the scraper frame is provided with an adapting groove 111 that is adapted to the size and number of the hanging hooks. The provision of the adapting groove 111 can effectively prevent the hanging hooks 151 from hindering the upward movement of the scraper frame 11.

[0043] In the initial state, the positions of the grille 3 and the scraper 11 are as shown in the figure. Figure 1 As shown in FIG. 1 , the scraper 11 is located below one side of the grille 3, and the scraper 11 is located at the end between the side plates 1, and at this time the wedge-shaped locking block 165 and the reset cone 1615 are as shown in FIG. Figure 5 As shown in;

[0044] The elastic force of the first spring 167 is greater than the elastic force of the second spring 1613, so that when the wedge-shaped locking block 165 clamps the reset cone 1615 under the elastic force of the first spring 167, it can drive the reset cone 1615 to overcome the pulling force of the second spring 1613 and move toward the direction of the non-return cone 1610;

[0045] The side plate 1 is installed inside the irrigation ditch and is attached to the inner walls on both sides of the ditch and connected by bolts. When in use, the water flow inside the ditch can be Figure 1The water passes through the holes on the grille 3 from left to right, while the larger impurities are filtered by the grille 3 and adhere to one side of the grille 3. As the grille 3 continues to filter, the impurities adhered to the outer wall of the grille 3 are too many and affect the normal passage of water. At this time, the impact force of the water flow on the grille 3 increases due to the blockage of the holes, and the grille 3 can overcome the elastic force of the arc leaf spring 7 and move. When the grille 3 moves, since the scraper 11 is connected to the grille 3 by the travel bolt 12 slidably connected to the inside of the first stroke groove 10, the lateral pulling force generated when the grille 3 moves to the right can drive the scraper 11 to move synchronously, but since the scraper 11 is connected to the side plate 1 by the travel rod 13 slidably connected to the inside of the second stroke groove 14, the scraper 11 will slide upward along the second stroke groove 14, and the grille 3 can drive the outer shell 161 to move toward the direction of the fixing rod 168 through the connecting rod 162;

[0046] When the scraper 11 moves upward along the side rod 4 and the second stroke groove 14, it can scrape off the impurities attached to the outer wall of the grille 3 and collect them in the aggregate mesh frame 15, thereby preventing the water flow from passing through the grille 3;

[0047] At this time, there are two states:

[0048] The first state: the impact force of the water flow on the grille 3 can make the grille 3 overcome the elastic force of the arc leaf spring 7 and drive the limit slider 5 to move to the end of the limit slide groove 6. At this time, the scraper 11 can completely move along the second stroke groove 14 to the top to scrape off some impurities on the grille 3 and collect them in the aggregate mesh frame 15. At this time, the connecting rod 162 and the outer shell 161 inside the non-return stroke assembly 16 can drive the wedge-shaped locking block 165 to clamp the reset cone 1615 as the grille 3 moves. In the process of the grille 3 being reset by the elastic force of the arc leaf spring 7, the wedge-shaped locking block 165 can drive the reset cone 1615 to overcome the pulling force of the second spring 1613 and fit with the non-return cone 1610, so that the wedge-shaped locking block 165 can be reset along the inclined surface of the reset cone 1615 and the inclined surface of the non-return cone 1610. At this time, the non-return stroke assembly 16 can complete a complete working cycle.

[0049] The second state: as the impurities are scraped off, the impact force of the water flow on the grille 3 is reduced. At this time, the impact force on the grille 3 may not be able to overcome the elastic force of the arc leaf spring 7, so that the grille 3 cannot continue to move. At this time, when the grille 3 moves a certain distance, it can drive the wedge-shaped locking block 165 inside the outer shell 161 to move between the check cone 1610 and the reset cone 1615 through the connecting rod 162. At this time, when the arc leaf spring 7 applies the resetting elastic force to the grille 3, the flat surface of the wedge-shaped locking block 165 fits the flat surface of the check cone 1610, so that the grille 3 cannot be reset. The grille 3 will remain motionless, and as the water flow continues to pass through, the impurities in it continue to increase. When the amount of water flowing through the grille 3 is insufficient, that is, the impact force of the water flow on the grille 3 can overcome the elastic force of the arc leaf spring 7, the grille 3 moves and drives the scraper 11 to continue to scrape off the impurities, and can drive the wedge-shaped locking block 165 inside the outer shell 161 to clamp the reset cone 1615 and reset it as above;

[0050] The scraper 11 can scrape off the impurities on the grille 3 during the movement, thereby preventing the grille 3 from being blocked by the impurities and affecting the normal irrigation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
