Description

Technical Field

[0001] This utility model belongs to the field of farmland drainage technology, specifically relating to an overflow drainage ditch for high-standard farmland. Background Technology

[0002] The overflow drainage ditches of high-standard farmland are the "flood control safety valves" of farmland. Their core function is to quickly and safely drain excess surface water in the fields in extreme situations such as heavy rain or irrigation system failure, so as to prevent waterlogging disasters in farmland.

[0003] In the prior art, patent number CN219315652U discloses a farmland drainage ditch, including a ditch body with a scraper installed inside. The outer wall of the scraper is in contact with the inner wall of the ditch body, and several filter holes are opened on the side of the scraper. A drive assembly for driving the scraper to move along the length of the ditch body is provided inside the ditch body. As a prior art drainage ditch, this application only uses a scraper to remove silt from the inner wall of the ditch body. However, in actual use, the filter holes of the scraper itself can be blocked by straw or soil debris in the farmland, hindering the drainage effect and making it impossible to drain waterlogged areas in time during heavy rain. Therefore, this application proposes a high-standard overflow drainage ditch for farmland. Utility Model Content

[0004] The purpose of this utility model is to provide an overflow drainage ditch for high-standard farmland, which solves the problem that the filter plates of existing drainage ditches are easily blocked by weeds and soil. This application replaces the blocked filter plates without affecting the normal use of the drainage ditch filter components, and can also clear straw or weeds in the drainage ditch. It can quickly and safely drain excessive water from the field, prevent waterlogging in the farmland, and ensure that high-standard farmland can achieve drought and flood protection and high and stable yields.

[0005] The specific technical solution adopted by this utility model is as follows: An overflow drainage ditch for high-standard farmland includes a drainage channel set between plots of land. A first rotating shaft is fixedly installed on the inner wall of one side of the drainage channel, and a second rotating shaft is movably connected to the inner wall of the other side of the drainage channel, with the second rotating shaft passing through the other side wall of the drainage channel. A roller is installed between the first rotating shaft and the second rotating shaft. One side wall of the roller is sleeved on the first rotating shaft, and the other side wall of the roller is fixedly connected to the second rotating shaft. Multiple filtering devices are provided inside the roller, and multiple impurity removal components are installed on the surface of the roller.

[0006] Preferably, the upper surface of the roller is provided with a plurality of equidistantly distributed filter grooves, the filter device includes filter plates installed in the filter grooves, the filter plates are provided with protrusions at the four corners, and the roller is provided with grooves at both ends, the grooves are adapted to the protrusions, and the protrusions and the grooves are connected by screws.

[0007] Preferably, the impurity removal component includes fixed blocks fixedly installed on the surfaces of both ends of the drum, a shaft is installed between the fixed blocks, a bent rod is fixedly installed on the surface of the shaft, a first circular hole and a second circular hole are opened at the end of the shaft, a bolt is provided on the side wall of the fixed block, when the bent rod is opened, the bolt is threadedly connected to the first circular hole, and when the bent rod is in contact with the filter sheet, the bolt is threadedly connected to the second circular hole.

[0008] Preferably, a rubber strip is fixedly connected to the inner wall at the bottom of the drainage channel. The rubber strip is inclined, and under the elasticity of the rubber strip itself, the top end of the rubber strip is in contact with the outer surface of the filter.

[0009] Preferably, the second rotating shaft has four third circular holes at its end, with an included angle of 90° between any two third circular holes. A handle is movably fitted onto the end of the second rotating shaft, and a first pin is movably fitted onto the handle. The first pin is adapted to be inserted into the third circular holes on the second rotating shaft.

[0010] Preferably, a first insert and a second insert are fixedly installed on one side wall of the drainage channel, and a second pin is movably connected to the middle of the handle, the second pin being adapted to and inserted into the first insert and the second insert.

[0011] Preferably, a water pump is installed on one side wall of the drainage channel, the input end of the water pump is connected through the side wall of the drainage channel, and the output end of the water pump is connected to a water pipe.

[0012] The technical effects achieved by this utility model are as follows: 1. After the water has flowed through the filter for a period of time, pull out the second pin, turn the handle to the upper insertion cylinder on the side wall of the drainage channel. The rotation of the handle will simultaneously rotate the drum, which in turn will rotate the impurity removal component. Then, insert the second pin into the insertion cylinder to fix the handle. Clean the impurities off the bent rod, and simultaneously remove the filter and clean it. After cleaning, reinstall it in the filter tank. Then, pull out the bolt, turn the shaft, and simultaneously rotate the bent rod. When the bent rod is in contact with the surface of the filter, insert the bolt into the second round hole. Pull out the first pin, and insert it into another third round hole to fix the handle. After the water has flowed through the filter for a period of time again, turn the handle back, which will then rotate the drum. When the handle is rotated to the horizontal insertion cylinder, insert the second pin into the insertion cylinder. Repeat the above operations to allow the filter to be replaced while the operation is in progress, improving work efficiency. The handle is embedded in the farmland, and its external protective shell protects the handle from environmental influences and makes rotation easier.

[0013] 2. When the water flows to the bottom of the drainage channel, the rubber strip will prevent the water from flowing directly into the bottom of the channel. The water must first flow through the filter before it can be discharged. During this process, the water flow squeezes the rubber strip, and the elasticity of the rubber strip makes it fit tightly with the filter, enhancing the sealing. Even if a small amount of water seeps out from the joint between the rubber strip and the filter in actual operation, it will not affect the overall working effect of the drainage system.

[0014] 3. This application replaces the clogged filter plate without affecting the normal use of the drainage ditch filter components. It can also clear straw or weeds in the drainage ditch, quickly and safely drain excess water from the field, prevent waterlogging in farmland, and ensure that high-standard farmland can achieve drought and flood protection and high and stable yields.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] An overflow drainage ditch for high-standard farmland includes a drainage channel 1 set between plots 13. A first rotating shaft 2 is fixedly installed on the inner wall of one side of the drainage channel 1, and a second rotating shaft 3 is movably connected to the inner wall of the other side of the drainage channel 1, with the second rotating shaft 3 penetrating through the other side wall of the drainage channel 1. A roller 4 is installed between the first rotating shaft 2 and the second rotating shaft 3. One side wall of the roller 4 is sleeved on the first rotating shaft 2, and the other side wall of the roller 4 is fixedly connected to the second rotating shaft 3. Multiple filter devices 5 are provided inside the roller 4, and multiple impurity removal components 6 are installed on the surface of the roller 4.

[0020] like Figures 1-10 As shown: This application replaces the clogged filter device 5 on the drum 4 without affecting the normal use of the drainage ditch filter components. At the same time, it can also clean the straw or weeds in the drainage ditch through the impurity removal component 6, which can quickly and safely drain the excess water in the field, prevent farmland waterlogging, and ensure that high-standard farmland can achieve drought and flood protection and high and stable yields.

[0021] Preferably, the upper surface of the roller 4 is provided with a plurality of equidistantly distributed filter grooves 501. The filter device 5 includes filter plates 502 installed in the filter grooves 501. The filter plates 502 are provided with protrusions 503 at the four corners. The roller 4 is provided with grooves 504 at both ends. The grooves 504 are adapted to the protrusions 503. The protrusions 503 and the grooves 504 are connected by screws.

[0022] Preferably, the impurity removal component 6 includes fixing blocks 601 fixedly installed on the surfaces of both ends of the drum 4, a shaft 602 installed between the fixing blocks 601, a bent rod 603 fixedly installed on the surface of the shaft 602, a first round hole 605 and a second round hole 606 opened at the end of the shaft 602, and bolts 604 provided on the side wall of the fixing blocks 601. When the bent rod 603 is open, the bolts 604 are threadedly connected to the first round hole 605. When the bent rod 603 is in contact with the filter sheet 502, the bolts 604 are threadedly connected to the second round hole 606.

[0023] like Figures 1-10 As shown: During the rainy season or heavy rain, the drainage ditch can quickly drain excess surface water from the fields, preventing crops from being soaked in water for a long time, preventing root rot due to lack of oxygen, and ensuring normal crop growth. Excess surface water first enters the drainage channel 1, and then flows forward through the drainage channel 1, passing through the filter 502 to filter out impurities in the water. The filtered water is then discharged into the river by the water pump 12, so that the water in the drainage channel 1 always flows towards the end where the water pump 12 is located. In the initial state, the end of bolt 604 engages with the first circular hole 605, causing the bent rod 603 to fit against the filter element 502. This facilitates the rotation of roller 4, enabling the bent rod 603 and filter element 502 to rotate simultaneously. When the filter element 502 rotates to the desired position... Figure 7 When the leftmost end is shown, pull the bolt 604 out of the first round hole 605, rotate the shaft 602 to drive the bent rod 603 to rotate, rotate the bent rod 603 to fit against the bottom upper surface of the drainage channel 1, and then thread the end of the bolt 604 to the second round hole 606 to limit the angle of the bent rod 603, so that the bent rod 603 can fork out weeds and straw when the roller 4 rotates.

[0024] After removing the impurities from the bent rod 603, unscrew the end of the bolt 604 from the second round hole 606, then rotate the shaft 602 again to drive the bent rod 603 to rotate, and rotate the bent rod 603 until it is in contact with the surface of the filter plate 502 again, so that the roller 4 can drive the bent rod 603 and the filter plate 502 to rotate simultaneously next time.

[0025] Preferably, the second rotating shaft 3 has four third circular holes 301 at its end, with an included angle of 90° between every two third circular holes 301. A handle 8 is movably sleeved on the end of the second rotating shaft 3, and a first pin 9 is movably provided on the handle 8. The first pin 9 is adapted to be inserted into the third circular holes 301 on the second rotating shaft 3.

[0026] Preferably, a first insert 16 and a second insert 10 are fixedly installed on one side wall of the drainage channel 1, and a second pin 11 is movably connected to the middle of the handle 8, the second pin 11 being adapted to be inserted into the first insert 16 and the second insert 10.

[0027] like Figures 1-10 As shown: When the filter needs to be disassembled and cleaned, the roller 4 is rotated, and the handle 8 drives the second shaft 3 to rotate 90°. Then, the second pin 11 is inserted into the second insert 10 to limit the angle of the roller 4. After the weeds and straw are cleared, and the filter 502 is disassembled, cleaned, and reinstalled, the second pin 11 and the first pin 9 are pulled out. The handle 8 is rotated counterclockwise. Since the first pin 9 has been pulled out, the handle 8 no longer drives the second shaft 3 to rotate. When the handle 8 returns to the initial horizontal position, the first pin 9 is reinserted into the corresponding third round hole 301 on the second shaft 3 to limit the angle of the roller 4. It should be noted that during the short period of time after the first pin 9 is pulled out, the damping effect between the second shaft 3 and the inner wall of the drainage channel 1 prevents the roller 4 from rotating easily. Only under the action of external force and the lever action of the handle 8 can the second shaft 3 be driven to rotate, thereby driving the roller 4 to rotate.

[0028] After removing impurities from the bent rod 603 and rotating it until it fits against the surface of the filter disc 502, and installing the cleaned filter disc 502 onto the roller 4, pull out the first pin 9 and the second pin 11, and rotate the handle 8 counterclockwise to a horizontal position. Then, the throttle 8 is fixed by inserting the second pin 11 into the first insert 16.

[0029] Preferably, a rubber strip 7 is fixedly connected to the inner wall of the bottom of the drainage channel 1. The rubber strip 7 is inclined and, under the elasticity of the rubber strip 7 itself, the top of the rubber strip 7 is attached to the outer surface of the filter sheet 502.

[0030] like Figures 1-10 As shown: When the accumulated water flows to the bottom of the drainage channel 1, the rubber strip 7 will prevent the water from flowing directly into the bottom of the channel. The water must first flow through the filter plate 502 before it can be discharged. During this process, the water flow squeezes the rubber strip 7. Utilizing the elasticity of the rubber strip 7 itself, it makes it fit tightly with the filter plate 502, enhancing the sealing performance. Even if a small amount of water seeps out from the joint between the rubber strip 7 and the filter plate 502 during actual operation, it will not affect the overall weed filtration effect of the drainage system.

[0031] Preferably, a water pump 12 is installed on one side wall of the drainage channel 1, with the input end of the water pump 12 connected through to the side wall of the drainage channel 1, and the output end of the water pump 12 connected to a water pipe.

[0032] like Figures 1-10 As shown: In practical applications, the throttle 8 is embedded in the farmland plot 13, and the protective shell 14 set on its exterior not only protects the throttle 8 from environmental influences, but also makes the rotation operation more convenient; the filtered water is discharged into the river through the water pump 12, which is embedded in the farmland plot 13 and is surrounded by a protective shell 15 to ensure that the water pump 12 can operate normally in the buried environment.

[0033] like Figure 9 As shown, in Figure 9 The break in the wavy line indicates that drainage channel 1 and plot 13 are still quite long; this is an abbreviated drawing method.

[0034] The working principle of this utility model is as follows: During the rainy season or heavy rain, the water on the surface of plot 13 will quickly flow into the drainage ditch 1. As the water flows forward, it will carry some weeds or straw. Therefore, after a certain period of time, the filter plate 502 will become clogged. In the initial state, the bent rod 603 is rotated to fit against the bottom upper surface of the drainage ditch 1. Weeds, straw, and soil will be filtered down by the bent rod 603 and the filter plate 502. When a certain amount of weeds and straw accumulate at the bent rod 603 and the filter plate 502 becomes clogged with silt, the second pin 11 is pulled out, and the handle 8 is rotated. The handle 8 drives the second shaft 3 to rotate 90°. With the cooperation of the first shaft 2, the roller 4 is driven to rotate 90°. At this time, the corresponding filter plate 502 and the bent rod 603 will be driven to rotate as follows. Figure 7 Rotate 90° clockwise as shown. The bent rod 603 on the leftmost filter 502 will then bend downwards, aligning with the bottom upper surface of the drainage channel 1. Insert the second pin 11 into the second insert 10 to secure the handle 8. Continue draining the water. The bent rod 603, carrying weeds and straw, will now be positioned to the side, facilitating the removal of any protruding weeds and straw. Remove the topmost filter 502, clean it, and reinstall it on the roller 4. Repeat these steps to replace the clogged filter device 5 on the roller 4 without affecting the normal filtration of weeds and straw in the drainage channel. Simultaneously, the cleaning component 6 can remove straw or weeds from the drainage channel, enabling rapid and safe drainage of excess water in the field, preventing waterlogging, and ensuring high-standard farmland achieves drought and flood resistance, high and stable yields.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
