Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural water and soil engineering technology, and in particular to an agricultural drainage buffer structure. Background Technology
[0002] Agriculture is an industry that utilizes the growth and reproduction patterns of plants and animals to obtain products through artificial cultivation. It is one of the most basic material production activities of humankind, including multiple branches such as crop cultivation, animal husbandry, fisheries, and forestry. These areas are interconnected and together constitute a complete agricultural system.
[0003] Existing drainage buffer structures rely on water pumps for drainage. For example, when the water level in a sedimentation pond rises rapidly and is about to overflow, the pumps installed in the pond can pump the water to surrounding backup reservoirs, drainage channels, and other safe areas. This prevents overflow from flooding surrounding land and avoids untreated water from directly entering downstream water bodies, which could damage crops and paddy fields. However, irrigation water contains silt, plant debris, and agricultural waste. Larger plant debris and agricultural waste can collide with crops during the flow, causing plant breakage and leaf damage. Current technology uses filters installed at the pump inlet to intercept larger impurities, such as branches, leaves, large pieces of agricultural waste, and large particles of silt, thus preventing damage to vegetation. However, over time, impurities accumulate on the filters, leading to blockage and increased resistance to water flow. This blockage prevents the drip irrigation system from functioning properly, affecting irrigation and drainage for crops. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an agricultural drainage buffer structure, which aims to improve the problem in the prior art where impurities accumulate on the filter screen after long-term use, leading to filter screen blockage and affecting irrigation and drainage of crops.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an agricultural drainage buffer structure, including a ditch, with square short blocks fixedly connected to the top left and right sides of the ditch, a bidirectional threaded rod rotatably connected to the middle of the square short blocks, and multiple cleaning brushes equidistantly threaded to the outer wall of the bidirectional threaded rod. A square filter screen is fixedly connected inside the ditch, a second gear is fixedly connected to the left end of the outer wall of the bidirectional threaded rod, a chain is installed on the outer wall of the second gear, a motor is fixedly connected to the left side of the outer wall of the ditch, a first gear is fixedly connected to the output end of the motor, the first gear and the second gear are connected by chain transmission, a long blade rod is fixedly connected to the right side of the outer wall of the first gear, elongated filter screens are engaged and connected to the left and right sides of the inner wall of the ditch, a sedimentation tank is installed on the rear side of the outer wall of the ditch, and a buffer mechanism is installed on the rear side of the ditch. The buffer mechanism is used to buffer the impact force of the water flow.
[0006] As a further description of the above technical solution:
[0007] The buffer mechanism includes a fixed block installed on the rear side of the outer wall of the ditch. Connecting rods are rotatably connected to both the upper and lower sides of the outer wall of the fixed block. A fixed long rod is fixedly connected to the middle of the fixed block. A spring is fixedly connected to the left end of the outer wall of the fixed long rod. A slider is slidably connected to the outer wall of the fixed long rod. Connecting rods are rotatably connected to both the upper and lower sides of the outer wall of the slider. A fixed plate is fixedly connected to the front end of the outer wall of the connecting rod. Multiple piston rods are equidistantly fixed to the front side of the outer wall of the fixed plate. A hollow cylinder is slidably connected to the outer wall of the piston rod. An elongated plate is fixedly connected to the other end of the outer wall of the hollow cylinder.
[0008] As a further description of the above technical solution:
[0009] A hollow box is fixedly connected to the left side of the outer wall of the sedimentation tank, and a drawer is slidably connected inside the hollow box.
[0010] As a further description of the above technical solution:
[0011] A second handle is fixedly connected to the left side of the outer wall of the drawer, and a second anti-slip sleeve is fixedly connected to the outer wall of the second handle.
[0012] As a further description of the above technical solution:
[0013] The top of the sedimentation tank is fixedly connected to a hinge, and an observation window is rotatably connected to the other side of the outer wall of the hinge.
[0014] As a further description of the above technical solution:
[0015] A handle is fixedly connected to the top of the observation window, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0018] As a further description of the above technical solution:
[0019] The bottom of the motor is fixedly connected with multiple feet at equal intervals, and the top of each foot is threaded with a screw.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the motor drives the first gear at the output end to rotate. Since the first gear is connected to the second gear via a chain, the bidirectional threaded rod rotates. When the bidirectional threaded rod rotates, the two cleaning brushes on the outer wall move left and right along the bidirectional threaded rod to clean the square filter screen. Finally, the long blade cuts and breaks up larger debris in the water flow, further ensuring the smooth flow of water. This avoids the problem of impurities accumulating on the filter screen after long-term use, which can lead to filter screen blockage and affect irrigation and drainage of crops.
[0022] 2. In this utility model, after the elongated plate is impacted by the water flow, it drives the hollow cylinder to move backward. Since the piston rod and the hollow cylinder are slidably connected, the piston rod will slide and squeeze inside the hollow cylinder to absorb part of the impact force of the water flow. At the same time, the movement of the elongated plate will drive the connecting rod two to rotate with the connecting rod one through the fixed plate. Therefore, the rotation of the connecting rod one will transfer part of the impact force to the slider, causing the slider to slide and squeeze the spring one on the outer wall of the fixed long rod, further absorbing and buffering the impact force of the water flow, thereby achieving the effect of reducing the speed and impact force of the water flow.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an agricultural drainage buffer structure, including a ditch 1. Square short blocks 15 are fixedly connected to the top left and right sides of the ditch 1. A bidirectional threaded rod 14 is rotatably connected to the middle of each square short block 15. The square short blocks 15 serve to fix the bidirectional threaded rod 14, which rotates. Multiple cleaning brushes 13 are equidistantly threaded onto the outer wall of the bidirectional threaded rod 14. A square filter screen 12 is fixedly connected inside the ditch 1. A gear 23 is fixedly connected to the left end of the outer wall of the bidirectional threaded rod 14. A chain 5 is installed on the outer wall of the gear 23. A motor 20 is fixedly connected to the left side of the outer wall of the ditch 1. Turning on the motor 20 drives a gear 21 to rotate. The output end of the motor 20 is fixedly connected to the gear 21. The gear 21 and the chain 5... Wheel 23 is connected by chain 5. A blade rod 22 is fixedly connected to the right side of the outer wall of gear 1. The rotation of gear 1 can drive the blade rod 22 to rotate and cut impurities. Long filter screens 11 are engaged and connected to the left and right sides of the inner wall of ditch 1. A sedimentation tank 4 is installed on the rear side of the outer wall of ditch 1. A buffer mechanism 2 is installed on the rear side of ditch 1. The buffer mechanism 2 is used to buffer the impact force of water flow. A hollow box 16 is fixedly connected to the left side of the outer wall of sedimentation tank 4. A drawer 19 is slidably connected inside the hollow box 16. The drawer 19 can facilitate the storage of tools for daily use and maintenance. A handle 2 18 is fixedly connected to the left side of the outer wall of drawer 19. The handle 2 18 can facilitate the opening and closing of drawer 19. An anti-slip sleeve 2 17 is fixedly connected to the outer wall of handle 2 18.
[0033] Specifically, the square filter screen 12 inside the ditch 1 initially filters and intercepts impurities in the water flow, preventing large particles from flowing out. Then, the motor 20 is turned on, driving the output gear 21 to rotate. Because gear 21 is connected to gear 23 via chain 5, it causes the bidirectional threaded rod 14 to rotate. When the bidirectional threaded rod 14 rotates, the two cleaning brushes 13 on the outer wall move left and right along the bidirectional threaded rod 14, cleaning the square filter screen 12 and brushing the impurities attached to the square filter screen 12 into the long filter screens 11 on both sides for storage. When gear 21 rotates, the blade rod 22 on the right side of gear 21 will also rotate, which can cut and crush larger debris in the water flow, further ensuring the smooth flow of water. A hollow box 16 is fixedly connected to the left side of the outer wall of the sedimentation tank 4. A drawer box 19 is slidably connected inside the hollow box 16. The drawer box 19 can conveniently store tools for daily use and maintenance. A handle 18 is fixedly connected to the left side of the outer wall of the drawer box 19. The handle 18 can facilitate opening and closing the drawer box 19. An anti-slip sleeve 17 is fixedly connected to the outer wall of the handle 18.
[0034] Reference Figure 2 , Figure 5 and Figure 6The buffer mechanism 2 includes a fixed block 201, which is installed on the rear side of the outer wall of the ditch 1. Connecting rods 209 are rotatably connected to both the upper and lower sides of the outer wall of the fixed block 201. A fixed long rod 202 is fixedly connected to the middle of the fixed block 201. A spring 204 is fixedly connected to the left end of the outer wall of the fixed long rod 202, which acts as a buffer for contraction. A slider 203 is slidably connected to the outer wall of the fixed long rod 202. Connecting rods 205 are rotatably connected to both the upper and lower sides of the outer wall of the slider 203, which acts as a rotatable connection. A fixed rod is fixedly connected to the front end of the outer wall of the connecting rod 209. Fixed plate 206, multiple piston rods 210 are fixedly connected at equal intervals on the front side of the outer wall of fixed plate 206, hollow cylinder 208 is slidably connected to the outer wall of piston rod 210, and long plate 207 is fixedly connected to the other end of the outer wall of hollow cylinder 208. Hinge 3 is fixedly connected to the top of sedimentation tank 4, and observation window 6 is rotatably connected to the other side of the outer wall of hinge 3.

Handle 7 can facilitate opening and closing observation window 6. Anti-slip sleeve 8 is fixedly connected to the outer wall of handle 7.
[0035] Specifically, the pre-treated water flows into the sedimentation tank 4 through the ditch 1. The impact force of the water flow first acts on the elongated plate 207. When the elongated plate 207 is impacted by the water flow, it drives the hollow cylinder 208 to move backward. Since the piston rod 210 is slidably connected to the hollow cylinder 208, the piston rod 210 will slide and compress inside the hollow cylinder 208 to absorb part of the impact force of the water flow. At the same time, the movement of the elongated plate 207 will drive the connecting rod 209 to rotate through the fixed plate 206, and the connecting rod 205 will rotate. The rotation will transfer some of the impact force to the slider 203, causing the slider 203 to slide and compress the spring 204 on the outer wall of the fixed rod 202, further absorbing and buffering the impact force of the water flow. The top of the sedimentation tank 4 is fixedly connected to the hinge 3, and the other side of the outer wall of the hinge 3 is rotatably connected to the observation window 6. The observation window 6 allows the staff to easily observe the inside of the sedimentation tank 4. The top of the observation window 6 is fixedly connected to the handle 7, which can be used to easily open and close the observation window 6. The outer wall of the handle 7 is fixedly connected to the anti-slip sleeve 8.
[0036] Reference Figure 1 and Figure 2A snap ring 10 is fixedly connected to the top front side of the sedimentation tank 4, and a snap fastener 9 is fixedly connected to the top front side of the observation window 6. The snap ring 10 and the snap fastener 9 are engaged and connected. By engaging and connecting the snap ring 10 and the snap fastener 9, the sealing of the observation window 6 can be enhanced, preventing impurities from entering the sedimentation tank 4 and causing pollution. Multiple support legs 24 are fixedly connected at equal intervals at the bottom of the motor 20. The support legs 24 can reinforce the motor 20 and prevent the motor 20 from shifting. The top of the support legs 24 is threaded with screws 25.
[0037] Specifically, a snap ring 10 is fixedly connected to the top front side of the sedimentation tank 4, and a snap fastener 9 is fixedly connected to the top front side of the observation window 6. The snap ring 10 and the snap fastener 9 are engaged and connected. By engaging and connecting the snap ring 10 and the snap fastener 9, the sealing of the observation window 6 can be enhanced, preventing impurities from entering the sedimentation tank 4 and causing pollution. Multiple support legs 24 are fixedly connected at equal intervals to the bottom of the motor 20. The support legs 24 can reinforce the motor 20 and prevent the motor 20 from shifting. The top of the support legs 24 is threaded with screws 25.
[0038] Working principle: The square filter screen 12 inside the ditch 1 initially filters and intercepts impurities in the water flow, preventing large particles from flowing out. Then, the motor 20 is turned on to drive the gear 21 at the output end to rotate. Since the gear 21 is connected to the gear 23 via the chain 5, the bidirectional threaded rod 14 rotates. When the bidirectional threaded rod 14 rotates, the two cleaning brushes 13 on the outer wall move left and right along the bidirectional threaded rod 14 to clean the square filter screen 12, brushing the impurities attached to the square filter screen 12 into the long filter screens 11 on both sides for storage. At the same time, when the gear 21 rotates, the blade rod 22 on the right side of the gear 21 also rotates, which can cut and break up larger debris in the water flow, further ensuring the smooth flow of water. This avoids the problem of impurities accumulating on the filter screen after long-term use, which can cause the filter screen to become clogged and affect the irrigation and drainage of crops.
[0039] The pre-treated water flows into the sedimentation tank 4 through the ditch 1. The impact force of the water flow first acts on the elongated plate 207. When the elongated plate 207 is impacted by the water flow, it drives the hollow cylinder 208 to move backward. Since the piston rod 210 is slidably connected to the hollow cylinder 208, the piston rod 210 will slide and squeeze inside the hollow cylinder 208 to absorb part of the impact force of the water flow. At the same time, the movement of the elongated plate 207 will drive the connecting rod 209 to rotate through the fixed plate 206 and the connecting rod 205. The rotation of the connecting rod 205 will transfer part of the impact force to the slider 203, causing the slider 203 to slide and squeeze the spring 204 on the outer wall of the fixed rod 202, further absorbing and buffering the impact force of the water flow, thereby achieving the effect of reducing the speed and impact force of the water flow.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
