Description

Technical Field

[0001] The present invention belongs to the technical field of comprehensive prevention and control of water erosion, and particularly relates to a device and method for comprehensive prevention and control of farmland water erosion. Background Art

[0002] Soil water erosion refers to the process of destruction, transportation, and deposition of surface materials under the action of water. The factor that has the greatest impact on soil water erosion is rainfall. The most severe erosion only occurs under moderate rainfall, severe damage to vegetation, and deforestation under high-intensity rainfall. At the same time, the problem lies not only in the "total amount" of rainfall but also in the "rainfall pattern". The violent heavy rainstorms in tropical regions have a more severe destructive effect than the relatively gentle rainfall in temperate regions.

[0003] Soil water erosion has led to serious consequences: First, the loss of fertile topsoil, which damages land resources, reduces land productivity, and affects food and ecological security; Second, the sediment siltation caused by the migration during the erosion process blocks rivers, lakes, and exacerbates droughts and floods. The migrated pollutants cause eutrophication of rivers, lakes, and reservoirs, etc., thus having a serious impact on the ecological environment and social economy in the downstream areas; Third, the erosion and transportation change the content and composition of soil carbon, nitrogen, and phosphorus, and further affect the global biogeochemical cycle of elements and even become an important driving factor for global climate change.

[0004] A farmland water erosion prevention device refers to a device or structure used to reduce or prevent soil erosion in farmland caused by water flow. Such devices usually combine agricultural techniques, water conservancy projects, and ecological protection measures to achieve the purpose of comprehensive management.

[0005] Common farmland water erosion prevention devices include: water retaining dams (intercepting ditches), whose function is to slow down the water flow velocity and reduce the erosion force by setting small water retaining dams or ditches on the ground surface; water storage tanks, whose function is to collect rainwater or surface runoff for irrigation or other purposes, reducing the amount of water directly scouring the ground; underground drainage systems, whose function is to drain excess groundwater through underground pipes or ditches, reducing the soil moisture content and reducing erosion caused by waterlogging; slope protection, whose function is to effectively reduce soil erosion caused by rainwater scouring in hilly areas or farmland with large terrain undulations, reducing the direct impact of rainwater on the ground surface and protecting farmland from water erosion hazards.

[0006] At present, in hilly areas or farmlands with large undulations, in order to prevent farmland water erosion, slope protection is mostly used to protect farmland from water erosion hazards, and a ditch is dug below the slope protection. However, in hilly areas or places with large undulations, with the washing of rainwater, stones are easily fallen. The current slope protection cannot handle the stones. Moreover, due to its hard texture and smooth slope, it will accelerate the rolling speed of the stones. The stones will not only cause the blockage of the ditch, affecting the drainage effect of the ditch, but also easily cause damage to the ditch, affecting the drainage effect of the ditch, and it is time-consuming and laborious to clean up, which is not convenient for long-term use.

[0007] The information disclosed in this background section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Invention

[0008] The purpose of the present invention is to provide a device and method for comprehensive prevention and control of farmland water erosion, which can solve the problems that the existing slope protection cannot handle stones, not only easily block the ditch, but also cause damage to the ditch, and it is time-consuming and laborious to clean up.

[0009] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the present invention is as follows:

[0010] A device and method for comprehensive prevention and control of farmland water erosion, comprising: a concrete slope, a rotating barrier mechanism, an impact buffer mechanism, an efficiency enhancement mechanism, and a plurality of pulling buffer mechanisms;

[0011] One side of the concrete slope is provided with a concrete ditch;

[0012] The rotating barrier mechanism is installed on one side of the concrete slope close to the concrete ditch for blocking stones;

[0013] Among them, the rotating barrier mechanism includes a barrier frame, a barrier impact net is fixedly installed in the barrier frame, and a pair of barrier support rods are rotatably installed in the barrier frame;

[0014] The impact buffer mechanism is arranged on the side of the barrier impact net away from the concrete ditch for protecting the barrier impact net;

[0015] A plurality of pulling buffer mechanisms are installed between the barrier frame and the concrete slope for enhancing the protection of the barrier impact net;

[0016] The efficiency enhancement mechanism is fixedly installed on the lower side of the concrete slope for enhancing the use effect of the rotating barrier mechanism.

[0017] In one or more embodiments of the present invention, a rotation groove matching the blocking frame is excavated on the concrete slope, which facilitates the rotation of the blocking frame and provides corresponding space for the rotation of the blocking frame, so that the blocking support rod can be better connected to the concrete slope;

[0018] A barrier bearing is installed between the barrier support rod and the barrier frame, which improves the smoothness of the barrier frame rotation and increases the friction between the barrier frame and the barrier support rod, so that the barrier frame can rotate smoothly after receiving a force;

[0019] The barrier support rod is fixedly installed with the concrete slope, which improves the stability of the barrier support rod, ensures the balance of the barrier support rod, and enables the barrier support rod to better support the rotation of the barrier frame.

[0020] In one or more embodiments of the present invention, the impact buffer mechanism includes an impact buffer guide plate, which can not only guide the stone after contacting the stone, but also buffer the stone by sliding after being hit by the stone, so as to reduce the probability of the stone being bounced off and make it easier for the stone to be guided by the impact buffer guide plate;

[0021] Both ends of the impact buffer guide plate are provided with impact buffer folding plates, which can support the impact buffer guide plate through the connection of the impact buffer mounting net, so that the impact buffer guide plate can better ensure the balance, and the guiding effect of the impact buffer guide plate is more ideal. At the same time, the impact buffer guide plate can move synchronously with the impact buffer folding plate;

[0022] An impact buffer installation net is fixedly installed between the impact buffer folding plate and the impact buffer guide plate, which not only connects the impact buffer guide plate and the impact buffer folding plate, but also ensures the connectivity between the impact buffer guide plate and the impact buffer folding plate, and enables the impact buffer guide plate to move synchronously with the impact buffer folding plate;

[0023] A pair of impact buffer accommodating chambers are provided on one side of the impact buffer folding plate close to the blocking frame, which facilitates the sliding of the impact buffer compression rod, makes the balance of the impact buffer compression rod more ideal, and provides corresponding space for the installation of the impact buffer compression spring.

[0024] In one or more embodiments of the present invention, the impact buffer storage bin is arranged to penetrate the barrier frame, which facilitates the installation of the impact buffer storage bin, ensures the installation space of the impact buffer storage bin, and reserves space for the sliding of the impact buffer compression rod;

[0025] The impact buffer accommodating bin is fixedly installed with the barrier frame. A sliding impact buffer compression rod is installed in the impact buffer accommodating bin, which can move synchronously through the movement of the impact buffer folding plate, so that the elastic force of the impact buffer compression spring can be applied to the impact buffer folding plate. The impact buffer compression rod is fixedly installed with the impact buffer folding plate;

[0026] An impact buffer compression spring is installed between the impact buffer compression rod and the impact buffer accommodating bin. When the impact buffer folding plate slides, the impact buffer compression spring can be compressed through the displacement of the impact buffer compression rod, so that the impact buffer compression spring buffers the sliding of the impact buffer folding plate, and further buffers the sliding of the impact buffer guiding plate.

[0027] In one or more embodiments of the present invention, the pulling buffer mechanism includes a pulling buffer follower bin, which facilitates the sliding of the pulling buffer follower plate, provides corresponding space for the sliding of the pulling buffer follower plate, and ensures the balance of the pulling buffer follower plate;

[0028] A sliding pulling buffer follower plate is installed in the pulling buffer follower bin, which can slide by the pulling of the pulling buffer straight rope, and at the same time apply corresponding force to compress the pulling buffer spring, so that the pulling buffer spring can buffer the pulling buffer follower plate;

[0029] A pulling buffer spring is installed between the pulling buffer follower plate and the pulling buffer follower bin, which can squeeze the pulling buffer follower plate to provide corresponding buffering for the pulling buffer follower plate;

[0030] A pulling buffer support rod is fixedly installed on the barrier frame, which facilitates the installation of the pulling buffer rotating ring, provides corresponding support for the fixation of the pulling buffer rotating ring, and enables the pulling buffer rotating ring to rotate on the pulling buffer support rod;

[0031] A torsion groove matching the pulling buffer support rod is drilled on the barrier frame, which facilitates the rotation of the pulling buffer rotating ring, provides corresponding space for the rotation of the pulling buffer rotating ring, and enables the pulling buffer rotating ring to rotate better.

[0032] In one or more embodiments of the present invention, a number of pulling buffer rotating rings are rotatably installed on the pulling buffer support rod, which can connect the pulling buffer support rod and the pulling buffer follower plate, so that when the barrier frame rotates, the relative displacement between the barrier frame and the pulling buffer support rod can be better;

[0033] A pulling buffer straight rope is installed between the pulling buffer rotating ring and the pulling buffer follower plate, connecting the pulling buffer follower plate and the pulling buffer rotating ring, so that the rotation of the barrier frame can pull the pulling buffer straight rope, and the pulling buffer follower plate can slide synchronously;

[0034] A pulling buffer shaft seat is fixedly installed on the concrete slope body, which can support the pulling buffer reel, provide corresponding space for the rotation of the pulling buffer reel, and assist in the balance of the pulling buffer reel;

[0035] The pulling buffer reel is rotatably installed on the pulling buffer shaft seat, and the pulling buffer rope can be wound around the pulling buffer reel, which facilitates the winding of the pulling buffer rope and enables the stretching of the pulling buffer rope to buffer the rotation of the barrier frame synchronously.

[0036] In one or more embodiments of the present invention, a pulling buffer return spring is installed between the pulling buffer reel and the pulling buffer shaft seat, which enables the pulling buffer rope to be wound better and enables the pulling buffer reel to be better buffered by the pulling buffer return spring when rotating;

[0037] A pulling buffer rope is installed between the pulling buffer reel and the pulling buffer follower bin, connecting the pulling buffer reel and the pulling buffer follower bin. When the pulling buffer follower bin is pulled by the pulling buffer straight rope, the pulling buffer reel rotates through the pulling of the pulling buffer rope and is buffered by the pulling buffer return spring;

[0038] A pulling buffer protection bin is provided outside the pulling buffer shaft seat, which can protect the pulling buffer reel, reduce the possibility of the pulling buffer reel being hit by stones, and reduce the probability of the pulling buffer reel being damaged. The pulling buffer protection bin is fixedly installed with the concrete slope body.

[0039] In one or more embodiments of the present invention, the efficiency-enhancing mechanism includes an efficiency-enhancing sinking bin, which can collect rainwater, reduce the probability of rainwater directly scouring the farmland, and enable the rainwater to flow into the concrete ditch better. The efficiency-enhancing sinking bin penetrates through the concrete slope body;

[0040] An efficiency-enhancing protection net is fixedly installed in the efficiency-enhancing sinking bin, which can reduce the possibility of stones entering the efficiency-enhancing sinking bin, reduce the probability of stones entering the concrete ditch, enable the stones to be better guided by the impact buffer guide plate, and enable the stones to enter the efficiency-enhancing cleaning bin for the convenience of the user to clean;

[0041] An efficiency-enhancing water flow pipe is installed between the efficiency-enhancing sinking bin and the concrete ditch, connecting the efficiency-enhancing sinking bin and the concrete ditch, and enabling the water in the efficiency-enhancing sinking bin to enter the concrete ditch better. The efficiency-enhancing water flow pipe penetrates through the efficiency-enhancing sinking bin and the concrete ditch;

[0042] In one or more embodiments of the present invention, an efficiency-enhancing cleaning bin is fixedly installed on the lower side of the concrete ditch, which facilitates the collection of stones and the cleaning of the user;

[0043] A pair of efficiency - enhancing stone pipes are installed between the efficiency - enhancing cleaning bin and the concrete slope, enabling the stones guided by the impact - buffering guide plate to enter the efficiency - enhancing stone pipes, so that the stones can better enter the efficiency - enhancing cleaning bin. The efficiency - enhancing stone pipes penetrate through the concrete slope and the efficiency - enhancing cleaning bin;

[0044] A number of uniformly distributed efficiency - enhancing guide plates are fixedly installed on the concrete slope, which can guide the stones, reducing the probability of the stones directly colliding with the efficiency - enhancing protection net and enhancing the protection of the efficiency - enhancing protection net;

[0045] An efficiency - enhancing guide frame is fixedly installed in the efficiency - enhancing cleaning bin, guiding the stones in the efficiency - enhancing cleaning bin, making it easier for the stones to fall at the outlet of the efficiency - enhancing cleaning bin and facilitating the cleaning by the user.

[0046] A method for comprehensive prevention and control of farmland water erosion includes the following steps:

[0047] S1. When rainwater scours and the stones roll and fall on the surface of the concrete slope, they will first come into contact with the efficiency - enhancing guide plates. During the rolling process of the stones, they will not come into contact with the efficiency - enhancing protection net, which can protect the efficiency - enhancing protection net and reduce the probability of the stones falling into the efficiency - enhancing sinking bin;

[0048] S2. After the smaller stones are guided by the efficiency - enhancing guide plates and come into contact with the impact - buffering guide plate, when the impact - buffering guide plate is collided by the stones, it will slide and compress the impact - buffering compression spring, enabling the impact - buffering compression spring to buffer the impact - buffering guide plate. This not only reduces the probability of the stones flying off but also protects the impact - buffering guide plate;

[0049] S3. After the larger - sized stones are guided by the efficiency - enhancing guide plates, they can not only be buffered by the impact - buffering guide plate but also cause the barrier frame to rotate through the impact, making the barrier frame pull the pulling - buffering follower plate. Through the extrusion of the pulling - buffering follower plate on the pulling - buffering spring, the pulling - buffering spring buffers the barrier frame;

[0050] S4. After the stones are buffered, they will be guided by the impact - buffering guide plate and fall into the efficiency - enhancing cleaning bin through the efficiency - enhancing stone pipes, and are guided by the efficiency - enhancing guide frame, facilitating the cleaning by the user;

[0051] S5. The rainwater flows downward on the concrete slope. A large amount of rainwater will enter the efficiency - enhancing sinking bin and flow into the concrete ditch through the efficiency - enhancing water flow pipe. A small amount of rainwater will be guided by the impact - buffering guide plate and flow into the concrete ditch through the impact - buffering installation net and the barrier impact net, achieving the effect of protecting the farmland.

[0052] Compared with the prior art, the device and method for comprehensive prevention and control of farmland water erosion according to the present invention can process stones through the setting of corresponding mechanisms, which not only reduces the probability of ditch blockage and the impact on the drainage effect of the ditch, but also reduces the damage to the ditch and the impact on the drainage effect of the ditch, and is easier to clean, facilitating long-term use.

[0063] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0064] like Figures 1 to 7 As shown, a device for comprehensive prevention and control of farmland water erosion in one embodiment of the present invention comprises: a concrete slope 1, a rotation blocking mechanism 2, an impact buffer mechanism 3, a synergistic mechanism 5 and a plurality of pulling buffer mechanisms 4.

[0065] like Figures 1 to 6 As shown, a concrete ditch 101 is provided on one side of the concrete slope 1, and a rotation blocking mechanism 2 is installed on the side of the concrete slope 1 close to the concrete ditch 101 for blocking stones, wherein the rotation blocking mechanism 2 includes a blocking frame 201, which can pull the pulling buffer follower plate 402 by rotating.

[0066] Among them, a blocking impact net 202 is fixedly installed in the blocking frame 201, which can block stones and does not hinder rainwater.

[0067] In addition, a pair of barrier support rods 203 are rotatably installed in the barrier frame 201 , and the barrier support rods 203 can be fixed to the concrete slope 1 , so that the barrier frame 201 can be positioned and the balance of the barrier frame 201 can be ensured.

[0068] As shown Figures 1 to 5 in the figure, a rotating groove matching the barrier frame 201 is chiseled on the concrete slope 1, which facilitates the rotation of the barrier frame 201, provides corresponding space for the rotation of the barrier frame 201, and enables the barrier support rod 203 to better connect with the concrete slope 1.

[0069] Among them, a barrier bearing 204 is installed between the barrier support rod 203 and the barrier frame 201, which improves the smoothness of the rotation of the barrier frame 201, increases the friction between the barrier frame 201 and the barrier support rod 203, and enables the barrier frame 201 to rotate smoothly after being subjected to force.

[0070] In addition, the barrier support rod 203 is fixedly installed with the concrete slope 1, which improves the stability of the barrier support rod 203, ensures the balance of the barrier support rod 203, and enables the barrier support rod 203 to better support the rotation of the barrier frame 201.

[0071] As shown Figures 1 to 5 in the figure, an impact buffer mechanism 3 is provided on the side of the barrier impact net 202 away from the concrete ditch 101 for protecting the barrier impact net 202. The impact buffer mechanism 3 includes an impact buffer guide plate 301, which can not only guide the stones after contacting with the stones, but also buffer the stones by sliding after being impacted by the stones, reducing the probability of the stones being bounced off and making it easier for the stones to be guided by the impact buffer guide plate 301.

[0072] Among them, impact buffer folding plates 302 are provided at both ends of the impact buffer guide plate 301, which can support the impact buffer guide plate 301 through the connection of the impact buffer installation net 303, making the impact buffer guide plate 301 better ensure balance, making the guiding effect of the impact buffer guide plate 301 more ideal, and at the same time the impact buffer guide plate 301 can move synchronously with the impact buffer folding plates 302.

[0073] In addition, an impact buffer installation net 303 is fixedly installed between the impact buffer folding plate 302 and the impact buffer guide plate 301, which not only connects the impact buffer guide plate 301 and the impact buffer folding plate 302, ensures the connectivity between the impact buffer guide plate 301 and the impact buffer folding plate 302, and enables the impact buffer guide plate 301 to move synchronously with the impact buffer folding plate 302.

[0074] In addition, a pair of impact buffer accommodating bins 304 are provided on the side of the impact buffer folding plate 302 close to the barrier frame 201, which facilitates the sliding of the impact buffer compression rod 305, makes the balance of the impact buffer compression rod 305 more ideal, and at the same time provides corresponding space for the installation of the impact buffer compression spring 306.

[0075] As shown Figures 1 to 4 in FIG. 2, the impact buffer accommodation bin 304 penetrates through the barrier frame 201, which facilitates the installation of the impact buffer accommodation bin 304, ensures the installation space of the impact buffer accommodation bin 304, and reserves space for the sliding of the impact buffer compression rod 305.

[0076] In addition, the impact buffer accommodation bin 304 is fixedly installed with the barrier frame 201. The impact buffer compression rod 305 is slidably installed in the impact buffer accommodation bin 304 and can move synchronously through the movement of the impact buffer folding plate 302, so that the elastic force of the impact buffer compression spring 306 can be applied to the impact buffer folding plate 302. The impact buffer compression rod 305 is fixedly installed with the impact buffer folding plate 302.

[0077] Furthermore, an impact buffer compression spring 306 is installed between the impact buffer compression rod 305 and the impact buffer accommodation bin 304. When the impact buffer folding plate 302 slides, the impact buffer compression spring 306 can be compressed through the displacement of the impact buffer compression rod 305, so that the impact buffer compression spring 306 buffers the sliding of the impact buffer folding plate 302, and further buffers the sliding of the impact buffer guiding plate 301.

[0078] As shown Figures 1 to 5 in FIG. 3, a plurality of pulling buffer mechanisms 4 are installed between the barrier frame 201 and the concrete slope 1 to enhance the protection of the barrier impact net 202. The pulling buffer mechanism 4 includes a pulling buffer follower bin 401, which facilitates the sliding of the pulling buffer follower plate 402, provides corresponding space for the sliding of the pulling buffer follower plate 402, and ensures the balance of the pulling buffer follower plate 402.

[0079] Among them, the pulling buffer follower plate 402 is slidably installed in the pulling buffer follower bin 401 and can slide through the pulling of the pulling buffer straight rope 406. At the same time, a corresponding force is applied to compress the pulling buffer spring 403, so that the pulling buffer spring 403 can buffer the pulling buffer follower plate 402.

[0080] In addition, a pulling buffer spring 403 is installed between the pulling buffer follower plate 402 and the pulling buffer follower bin 401, which can squeeze the pulling buffer follower plate 402 to provide corresponding buffering for the pulling buffer follower plate 402.

[0081] Moreover, a pulling buffer support rod 404 is fixedly installed on the barrier frame 201, which facilitates the installation of the pulling buffer swivel ring 405, provides corresponding support for the fixation of the pulling buffer swivel ring 405, and enables the pulling buffer swivel ring 405 to rotate on the pulling buffer support rod 404.

[0082] Among them, a torsion groove matching the pulling buffer support rod 404 is formed on the barrier frame 201, which facilitates the rotation of the pulling buffer swivel 405, provides corresponding space for the rotation of the pulling buffer swivel 405, and enables the pulling buffer swivel 405 to rotate better.

[0083] As Figures 1 to 6 shown, a number of pulling buffer swivels 405 are rotatably installed on the pulling buffer support rod 404, which can connect the pulling buffer support rod 404 and the pulling buffer follower plate 402, enabling the barrier frame 201 to have better relative displacement with the pulling buffer support rod 404 when rotating.

[0084] In addition, a pulling buffer straight rope 406 is installed between the pulling buffer swivel 405 and the pulling buffer follower plate 402, connecting the pulling buffer follower plate 402 and the pulling buffer swivel 405, enabling the rotation of the barrier frame 201 to pull the pulling buffer straight rope 406 and enabling the pulling buffer follower plate 402 to slide synchronously.

[0085] In addition, a pulling buffer shaft seat 407 is fixedly installed on the concrete slope 1, which can support the pulling buffer reel 408, provide corresponding space for the rotation of the pulling buffer reel 408, and assist in improving the balance of the pulling buffer reel 408.

[0086] Among them, a pulling buffer reel 408 is rotatably installed on the pulling buffer shaft seat 407, and the pulling buffer rope 410 can be wound around the pulling buffer reel 408, which facilitates the winding of the pulling buffer rope 410 and enables the stretching of the pulling buffer rope 410 to buffer the rotation of the barrier frame 201 synchronously.

[0087] As Figures 1 to 7 shown, a pulling buffer return spring 409 is installed between the pulling buffer reel 408 and the pulling buffer shaft seat 407, enabling the pulling buffer rope 410 to be wound better and enabling the pulling buffer reel 408 to be buffered by the pulling buffer return spring 409 better when rotating.

[0088] Among them, a pulling buffer rope 410 is installed between the pulling buffer reel 408 and the pulling buffer follower bin 401, connecting the pulling buffer reel 408 and the pulling buffer follower bin 401. When the pulling buffer follower bin 401 is pulled by the pulling buffer straight rope 406, the pulling buffer reel 408 is rotated through the pulling of the pulling buffer rope 410 and buffered by the pulling buffer return spring 409.

[0089] In addition, a pulling buffer protection chamber 411 is provided outside the pulling buffer shaft seat 407, which can protect the pulling buffer reel 408, reduce the possibility of the pulling buffer reel 408 being hit by stones, and reduce the probability of damage to the pulling buffer reel 408. The pulling buffer protection chamber 411 is fixedly installed with the concrete slope 1.

[0090] As Figures 1 to 7 shown, an efficiency enhancement mechanism 5 is fixedly installed on the lower side of the concrete slope 1 for enhancing the use effect of the rotation blocking mechanism 2. The efficiency enhancement mechanism 5 includes an efficiency enhancement sinking chamber 501, which can collect rainwater, reduce the probability of rainwater directly scouring the farmland, and make the rainwater flow better into the concrete ditch 101. The efficiency enhancement sinking chamber 501 penetrates through the concrete slope 1.

[0091] Among them, an efficiency enhancement protection net 502 is fixedly installed in the efficiency enhancement sinking chamber 501, which can reduce the possibility of stones entering the efficiency enhancement sinking chamber 501, increase the probability of stones entering the concrete ditch 101, make the stones better guided by the impact buffer guide plate 301, and make the stones enter the efficiency enhancement cleaning chamber 504, facilitating the user to clean.

[0092] In addition, an efficiency enhancement water flow pipe 503 is installed between the efficiency enhancement sinking chamber 501 and the concrete ditch 101, connecting the efficiency enhancement sinking chamber 501 and the concrete ditch 101, making the water in the efficiency enhancement sinking chamber 501 flow better into the concrete ditch 101. The efficiency enhancement water flow pipe 503 penetrates through the efficiency enhancement sinking chamber 501 and the concrete ditch 101.

[0093] As Figures 1 to 6 shown, an efficiency enhancement cleaning chamber 504 is fixedly installed on the lower side of the concrete ditch 101, facilitating the collection of stones and the cleaning by the user.

[0094] Among them, a pair of efficiency enhancement stone pipes 505 are installed between the efficiency enhancement cleaning chamber 504 and the concrete slope 1, enabling the stones guided by the impact buffer guide plate 301 to enter the efficiency enhancement stone pipes 505 and making the stones better enter the efficiency enhancement cleaning chamber 504. The efficiency enhancement stone pipes 505 penetrate through the concrete slope 1 and the efficiency enhancement cleaning chamber 504.

[0095] In addition, a number of uniformly distributed efficiency enhancement guide plates 506 are fixedly installed on the concrete slope 1, which can guide the stones, reduce the probability of the stones directly colliding with the efficiency enhancement protection net 502, and enhance the protection of the efficiency enhancement protection net 502.

[0096] In addition, an efficiency enhancement guide frame 507 is fixedly installed in the efficiency enhancement cleaning chamber 504, guiding the stones in the efficiency enhancement cleaning chamber 504, making the stones more likely to fall at the outlet of the efficiency enhancement cleaning chamber 504, and facilitating the cleaning by the user.

[0097] A method for comprehensive prevention and control of farmland water erosion, comprising the following steps:

[0098] S1. When rainwater washes and causes stones to roll and fall on the surface of the concrete slope 1, they will first come into contact with the efficiency-enhancing guide plate 506. During the rolling process of the stones, they will not come into contact with the efficiency-enhancing protection net 502, which can protect the efficiency-enhancing protection net 502 and reduce the probability of stones falling into the efficiency-enhancing sinking bin 501.

[0099] S2. After being guided by the efficiency-enhancing guide plate 506, the smaller stones come into contact with the impact buffer guide plate 301. After being collided by the stones, the impact buffer guide plate 301 will slide and compress the impact buffer compression spring 306, enabling the impact buffer compression spring 306 to buffer the impact buffer guide plate 301. This not only reduces the probability of the stones flying off but also protects the impact buffer guide plate 301.

[0100] S3. After being guided by the efficiency-enhancing guide plate 506, the larger stones can not only be buffered by the impact buffer guide plate 301 but also cause the barrier frame 201 to rotate through impact, causing the barrier frame 201 to pull the pull buffer follower plate 402. By squeezing the pull buffer spring 403 through the pull buffer follower plate 402, the pull buffer spring 403 buffers the barrier frame 201.

[0101] S4. After being buffered, the stones will be guided by the impact buffer guide plate 301 and fall into the efficiency-enhancing cleaning bin 504 through the efficiency-enhancing stone pipe 505 and be guided by the efficiency-enhancing guide frame 507, facilitating the cleaning by the user.

[0102] S5. When rainwater flows downward on the concrete slope 1, a large amount of rainwater will enter the efficiency-enhancing sinking bin 501 and flow into the concrete ditch 101 through the efficiency-enhancing water flow pipe 503. A small amount of rainwater will be guided by the impact buffer guide plate 301 and flow into the concrete ditch 101 through the impact buffer installation net 303 and the barrier impact net 202, achieving the effect of protecting the farmland.
