Description

Technical Field

[0001] The invention relates to the technical field of farmland drainage, and in particular to a farmland drainage ditch cleaning device. Background Art

[0002] The farmland drainage system is a general term for drainage ditches, pipes, pumping stations and other buildings at all levels that drain excess surface water, groundwater and soil water from farmland. Most of the farmland drainage ditches are set up as open ditches for drainage. However, in the process of farmers' cultivation of farmland, not only excess irrigation water is generated, but also some domestic garbage is mixed in the excess water. Therefore, it is necessary to clean the drainage ditches regularly to prevent these domestic garbage from being discharged into large water bodies with the water flow and polluting water resources.

[0003] The drainage ditches commonly used in farmland are mostly narrow structures, so as not to occupy too much agricultural land. The concrete slope protection cast on both sides ensures that the drainage ditch will not collapse. Then a waterway connecting the drainage ditch is set at the corresponding position of the farmland, and a gate to intercept the water flow is installed in the waterway. When there is too much water in the farmland, farmers will open the drainage gate to drain the water into the drainage ditch. During the drainage process, farmers need to clean and salvage the drainage ditch. The generally used method is for farmers to use a scoop net to clean it or use a fixed sewage net to intercept the garbage.

[0004] Although the existing sewage discharge method has achieved the purpose of intercepting pollution, farmers need to salvage at a high frequency to ensure that the garbage is cleared out in time, and the discharged water flows out from the farmland, so some soil will be entrained in the water flow. In the long run, it will not only cause siltation at the sewage interception net, but also accumulate over the years, and cause siltation in the river channel where the sewage is discharged and the water environment to be polluted. In view of this, the present invention proposes a farmland drainage ditch cleaning equipment. Summary of the invention

[0020] The technologies not mentioned in this invention are all prior arts.

[0021] Beneficial effects: Compared with the known public technologies, the technical solution provided by the present invention has the following beneficial effects:

[0022] 1. The present invention is provided with a soil filter assembly. Through the special transmission structure arranged in the vertical groove, the rotating shaft can drive two annular metal soft ropes to rotate during rotation, and then the two will drive the gauze to rotate. When the gauze closes the open end at the rear side of the through-hole, the soil that is not blocked by the baffle in the water flow can be intercepted. Because the soil will produce viscosity after meeting water, and the texture of the gauze is more convenient for the adhesion of the mud and water mixture, the mud and water mixture will be driven into the cavity in the subsequent rotation of the gauze, and finally scraped off under the action of the structure in the cavity and then collected uniformly in the position below the partition inside the collection box, which not only prevents the mud and water mixture from being discharged into the external water body to pollute the water resources environment, but also facilitates farmers to backfill the intercepted soil into the farmland. Compared with the existing method of intercepting soil through a densely meshed sewage intercepting net, the device can more effectively intercept the soil entrained in the water flow in the drainage ditch, and will not cause the problem of clogging the sewage cleaning mechanism and causing siltation in the drainage ditch, which not only enhances environmental protection, but also relieves the hard work of farmers.

[0023] 2. The present invention is provided with a cleaning mechanism. The rotating plate in this structure cooperates with the V-shaped guide plate to guide the water flow in the drainage ditch to the concave surface of the rotating plate in a more targeted manner. Then, under the action of the impact force of the water flow, the device can realize self-operation without an electric power source. In this way, the device can automatically open or stop according to whether the farmer opens the drainage gate. This not only greatly saves electricity resources, but also compares with the use of electric power sources. The device does not have any electrical equipment, so it will not be damaged by water vapor, thereby increasing its service life and enhancing the energy saving and environmental protection of the device. On the other hand, the cleaning mechanism can use water power to drive the lifting plate to rotate while performing reciprocating lifting and lowering motions, and then when it rotates to the discharge port, the garbage is uniformly collected in the position above the partition in the collection box, which will not allow the garbage to affect the smooth flow of the device and is also convenient for farmers to clean up. The design is ingenious and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 are within the scope of protection of the present invention.

[0038] A farmland drainage ditch cleaning equipment, reference Figure 1-11, including a shell 1, a through opening 2 is provided on the upper part of the shell 1, the through opening 2 is connected to the front and rear sides of the shell 1, a guide slope 201 is provided at the front end of the bottom of the through opening 2, and the guide slope 201 is a slanted structure with a low front and a high rear. Under such a structure, water flow can easily rush into the interior of the device from the guide slope 201, reducing the consumption of the water flow impulse by the front wall of the shell 1, a guide plate 3 is fixed at the opening end of the through opening 2, the front wall of the guide plate 3 is a V-shaped structure, a through groove 4 is provided in the middle of the front wall of the guide plate 3, and a baffle is fixed on the rear wall of the guide plate 3 relative to the through groove 4 5. The baffle 5 is an arc-shaped structure with the opening end facing forward. The front position mentioned here corresponds to the side where the water flows into the device. The middle position of the guide plate 3 is an arc structure. The arc surface position is equal to the curvature of the outer wall of the baffle 5, and its V-shaped structure is also designed with the tip facing backward, so that the water entering the through-hole 2 can be concentrated to the position on one side of the inside of the baffle 5, and the inclined surface design can minimize the consumption of the water flow impulse. A cleaning mechanism 6 is provided on the inner side of the baffle 5, and the cleaning mechanism 6 is used to clean up the garbage mixed in the water flow;

[0039] The cleaning mechanism 6 includes a rotating shaft 7 rotatably connected to the bottom surface of the through-port 2, the top surface of the rotating shaft 7 is in clearance with the top surface of the through-port 2, a vertical groove 8 is provided through the middle of the rotating shaft 7, the vertical groove 8 is a cylindrical structure, and a soil filter component 9 is provided inside the vertical groove 8. The soil filter component 9 is used to filter out the soil in the residual water of the farmland to prevent it from mixing in the residual water and entering the external water body. These soils entering the external water body will cause siltation, and too much silted soil will affect the water quality of the external water body, especially the soil in the farmland is relatively fertile soil, which is more likely to cause pollution. The setting of the soil filter component 9 can prevent the disadvantages of these soils from flowing into the river and silting up, thereby achieving the purpose of environmental protection;

[0040] The soil filter assembly 9 includes two metal soft ropes 10 symmetrically arranged inside the vertical groove 8. The metal soft ropes 10 are arranged in a rectangular ring structure. The two metal soft ropes 10 are arranged in an eight-shaped structure with a small front and a large back. The front sides of the two are both located in the vertical groove 8. A cavity 11 is opened in the housing 1 relative to the lower part of the metal soft rope 10. The cavity 11 is used to collect and accommodate soil filtered out of the water flow. Since the cavity 11 is connected to the outside at the rear side, the external water flow cannot rush into the cavity 11 when entering the device, so the soil collected in the cavity 11 will not be scattered by the impact of the water flow, and can slowly settle at the bottom of the cavity 11. The lower end of the rotating shaft 7 passes through the bottom surface of the through-hole 2 and extends to Inside the cavity 11, the rotating shaft 7 is rotatably connected to the bottom surface of the through-port 2, and the metal soft rope 10 is slidably connected to the vertical groove 8, the rear of the cavity 11 and the rear of the through-port 2. Its annular structure is formed by the restriction of the sliding connection structure at various places. Gauze 12 is fixed between the two metal soft ropes 10. Under the structural design of the metal soft rope and the interception of the gauze 12, the soil filter component 9 of the device can not only filter and collect soil in the residual water of the farmland, but also form an annular semi-enclosed structure at the rear of the through-port, so that the soil is confined in the cavity 11, and the garbage is confined to the position between the baffle 5 and the gauze 12, which not only prevents the two from escaping the interception of the device, but also makes it more convenient for farmers to clean the device;

[0041] A collecting box 13 is provided on one side of the rear portion of the through-port 2, and the collecting box 13 is used to receive domestic garbage and soil. A movable door 14 is hingedly provided on the top surface of the outer shell 1 relative to the collecting box 13. Farmers can regularly take out the collecting box 13 from the movable door 14 to clean the garbage and soil therein, and can also fully clean the through-port 2 and the inside of the cavity 11 from here during non-drainage time. Because of the setting of the collecting box 13, the garbage and soil intercepted in the device can have a collection point that will not hinder the flow of water, and can also extend the cycle of farmers cleaning the drainage ditch, saving time and effort.

[0042] Specifically, the rotating shaft 7 and the baffle plate 5 are located on the same axis, and the outer wall of the rotating shaft 7 is an annular structure with equal spacing and is fixed with a plurality of rotating plates 15. The rotating plate 15 is an arc structure. The design of the arc structure makes it easier for the impact force of the external water flow to push the rotating plate 15 of the device to drive the rotating shaft 7 to rotate, thereby improving the utilization of water power, so that the device can operate independently without external electricity as a power source, so that the device can operate independently according to the drainage time, and finally the device can operate smoothly and flexibly without an electric power source, achieving the effect of energy saving and emission reduction. The outer end of the rotating plate 15 is in sliding contact with the inner wall of the baffle plate 5, and a large volume of solid cannot be squeezed out from between the two. A lifting plate 16 is provided between two adjacent rotating plates 15, and the outer walls on both sides of the lifting plate 16 are in sliding contact with the two adjacent rotating plates 15 respectively. When the lifting plate 16 moves up and down, a large volume of solid cannot leak out from the gap between the rotating plate 15 and the lifting plate 16, and the outer end of the lifting plate 16 is in sliding contact with the inner wall of the baffle plate 5, and a large volume of solid cannot be squeezed out from between the two.

[0043] Furthermore, the inner end of the lifting plate 16 is slidably connected to the rotating shaft 7, and a T-shaped slider is fixedly arranged on the inner end of the lifting plate 16. A T-shaped slide groove that slides with the rotating shaft 7 is provided at a position relative to the T-shaped slide groove, so that the lifting plate 16 will not deviate from the predetermined trajectory during the up and down movement. A guide block 17 is fixedly arranged on the end of the outer wall of the lifting plate 16. The guide block 17 is a hemispherical structure. A first guide groove 18 is provided on the inner wall of the baffle 5. The first guide groove 18 is a curved structure, and its two end points both span along the inner arc wall of the baffle 5. The first guide groove 18 has a certain arc and is also lifted to a certain height. The size design of the first guide groove 18 allows the guide block 17 to easily rise along the first guide groove 18 and continue to rotate during the rotation. Because of the buoyancy of water during the rising process, the rising process is not entirely the squeezing effect of the first guide groove 18 on the guide block 17. Therefore, the rise at this point does not require a power exceeding the gravity of the lifting plate 16. However, because the gravity of the lifting plate 16 itself is much greater than the buoyancy generated by water on it, the lifting plate 16 is not affected by the first guide groove 18 and the buoyancy of water. The second guide groove 19 is a circular arc structure. The guide block 17 is slidably matched with the first guide groove 18 and the second guide groove 19. The higher second guide groove 19 is designed to be longer, so that the lifting plate 16 has enough time to flatten the garbage and push the garbage out. The lower second guide groove 19 is set larger than the distance between the guide block 17 and the lifting plate 16 on the edge closer to it, which can prevent the solid garbage entering the device from drilling into the bottom of the lifting plate 16 and affecting the operation of the device. A plurality of through holes 20 are evenly provided on the baffle plate 5 relative to the positions outside the first guide groove 18 and the second guide groove 19. The size of the through hole 20 can block the garbage in the water. The size of the through hole 20 is much larger than the soil particles entrained in the water, so it will not be blocked by the soil while intercepting the garbage. On the other hand, during the rotation of the rotating plate 15 and the up and down movement of the lifting plate 16, the two can also produce a scraping effect on the inner wall of the baffle plate 5 to prevent the soil from adhering to the inner wall of the baffle plate 5.

[0044] Furthermore, a top plate 21 is fixedly arranged on the top surface of the baffle 5. The top plate 21 is a cup-shaped structure with a concave surface facing downward. The height of the top surface on the inner side is much higher than the height of the top surface when the lifting plate 16 is at the highest point. The space between the two is sufficient to accommodate some garbage and can compress the excess space in the garbage to avoid excessive space waste between the garbage falling into the collection box 13, which causes a reduction in the collection amount of the device. Furthermore, because of the buoyancy in the water and the limited time for each lifting plate 16 to penetrate the groove 4, the garbage fished out by each lifting plate 16 is also limited, and there is enough space, so the device can be completely prevented from stopping due to excessive garbage. The upper end of the rotating shaft 7 penetrates the upper wall of the top plate 21 and is rotatably connected to the top plate 21. The top plate 21 is also used to prevent garbage from being moved along with the lifting In order to prevent the lifting plate 16 from falling out of the baffle 5 too early after rising, a discharge port 22 is provided on the top plate 21 relative to the collecting box 13, and the position of the discharge port 22 corresponds to the position of the second guide groove 19 located at the upper portion. When the guide block 17 drives the lifting plate 16 to rise to the highest point of the first guide groove 18, the top surface of the lifting plate 16 will be slightly higher than the bottom surface of the discharge port 22, so that the garbage on the lifting plate 16 can be pushed out from the discharge port 22 and fall into the collecting box 13 next to the discharge port 22, and the second guide groove 19 located at the upper portion can provide the lifting plate 16 with sufficient time to dump the garbage. The bottom surface of the lifting plate 16 is also designed as an inclined structure with a high inside and a low outside, which is convenient for the garbage to slide out. When the guide block 17 moves out of the second guide groove 19 at the upper portion, it will sink into the water under the action of gravity.

[0045] Furthermore, the through-hole 2 is connected with the cavity 11 through the vertical groove 8, and the soil adhered to the gauze 12 will enter the cavity 11 along with the metal cord 10 through the vertical groove 8. A spiral block 23 is fixed on the inner wall of the vertical groove 8. The spiral block 23 is a structure similar to the outer wall thread of a screw, but it protrudes from the inner wall of the vertical groove 8. The outer wall of the metal cord 10 is provided with a plurality of arc grooves 24 in an equidistant structure relative to the position of the spiral block 23. The arc grooves 24 are meshed and connected with the spiral block 23. The curvature and size of the arc grooves 24 are the same as those of each turn structure of the spiral block 23. In this way, when the spiral block 23 rotates with the rotating shaft 7, the arc groove 24 will continue to move downward along the spiral trajectory of the spiral block 23, thereby achieving the purpose of making the metal cord 10 and the gauze 12 circulate. Moreover, both ends of the spiral block 23 are spherical structures, which makes it easier for the arc groove 24 newly entering the vertical groove 8 to quickly mesh with the spiral block 23.

[0046] Furthermore, a limit plate 25 is provided in the middle of the vertical groove 8, and both sides of the limit plate 25 are arc-shaped structures. The outer walls on both sides of the limit plate 25 are in sliding contact with the outer walls of the two metal ropes 10 respectively, so as to limit the relative positions of the two metal ropes 10 in the vertical groove 8, which not only prevents the arc groove 24 from detaching from the spiral block 23, but also allows the spiral block 23 to avoid self-rotation, thereby allowing the metal ropes 10 to rotate stably. The upper and lower ends of the limit plate 25 respectively pass through the open ends on both sides of the vertical groove 8 and extend to the inside of the through-port 2 and the inside of the cavity 11 respectively. The upper and lower ends of the limit plate 25 are respectively connected and fixed to the top surface of the top plate 21 and the top surface of the cavity 11 through the connecting plate 26. The bottom surface of the cavity 11 is an inclined structure, and the soil concentrated in the cavity 11 will slide to a lower position along the inclined surface after sedimentation.

[0047] It is worth mentioning that side grooves 27 are provided on the inner walls of the through-hole 2 and the inner walls of the cavity 11 relative to the position of the metal cord 10, and a fixing plate 28 is fixed inside the side groove 27. The cross section of the fixing plate 28 is a two-thirds circular ring structure. The metal cord 10 slides in cooperation with the fixing plate 28. The upper and lower sides of the metal cord 10 are linearly and evenly spaced and are provided with a plurality of fixing rings 29. The fixing ring 29 is an annular structure with a notch, and the position of the notch and the position of the notch of the fixing plate 28 correspond to the connection position of the metal cord 10 and the gauze 12. The plurality of fixing rings 29 on the upper and lower sides are respectively connected and fixed to the top surface of the through-hole 2 and the bottom surface of the cavity 11. These structures are used to limit the direction of the metal cord 10 to prevent its direction from being uncontrolled and affecting the operation of other structures.

[0048] It is worth mentioning that the rear part of the gauze 12 is set in a taut state, and soil will be mixed in the water flow passing through the through hole 20. These soils with a certain viscosity will adhere to the gauze 12 due to the material of the gauze 12, and the taut gauze will intercept the rear opening end of the through hole 2 to prevent the seepage of soil to the greatest extent. A connecting groove 30 is provided between the through hole 2 and the cavity 11 relative to the position of the gauze 12. The size of the connecting groove 30 is the same as that of the taut gauze 12, which can fully prevent the gauze 12 from bringing the soil out of the cavity 11 again. A scraper 31 is fixedly provided on the top surface of the cavity 11 relative to the front side of the connecting groove 30, and the lower end of the scraper 31 is a V-shaped knot The scraper 31 is used to scrape off the mud adhering to the gauze 12, further preventing the mud from being taken out of the cavity 11, and ensuring that the mud can be concentrated in the cavity 11 waiting for precipitation. The arc grooves 24 on the metal soft rope 10 in the device are designed to be relatively dense, and the spacing between each turn of the spiral block 23 is also small, so the movement of the gauze 12 will be relatively slow, preventing its too fast rotation from affecting the precipitation effect of the soil, and the end of the rotating shaft 7 is higher than the top plate 21, and the height of the top plate 21 is higher than the standard height of the drainage ditch, so the water in the cavity 11 will not overflow from the upper opening end of the vertical groove 8 due to the change in water level.

[0049] It is worth noting that the collecting box 13 is of a fan-shaped structure, with two grooves 32 symmetrically provided on the upper end of the inner wall of the collecting box 13, a box groove 33 slidably matched with the collecting box 13 is provided on the bottom surface of the through-port 2, a slot 34 plugged into and matched with the collecting box 13 is provided on the bottom surface of the cavity 11, and the slot 34 is located on the side of the bottom surface of the cavity 11 with a lower height, a partition 35 is fixedly provided inside the collecting box 13 relative to the bottom surface of the through-port 2, a feeding port 36 is provided on the lower end of the outer wall of the collecting box 13 on the side close to the gauze 12, and blocks 37 are fixedly provided on the bottom surface of the cavity 11 relative to the front and rear sides of the collecting box 13. The blocks 27 can prevent the soil in the cavity 11 from concentrating on the two sides that are not conducive to cleaning by farmers.

[0050] The sealing plate 38 is slidably connected to the side of the gauze 12 on the upper side of the inner part of the collecting box 13, and a plate groove 39 is provided on the partition 35 for slidingly cooperating with the sealing plate 38. A plurality of circular grooves 40 are evenly provided on the inner wall of the plate groove 39, and a clamping block 42 is fixedly provided on the inner wall of the circular groove 40 by a compression spring 41. The clamping block 42 has a hemispherical structure, and a plurality of clamping blocks 42 are used to hold up the sealing plate 38, so that the soil of the device can be concentrated under the partition 35 as usual during use. When farmers are cleaning, they only need to press down the sealing plate 38 to close the feed port 36 to prevent leakage of soil during the lifting process. The clamping block 42 is used to fix the position of the sealing plate 38 so that it will not fall automatically without the influence of external force. Furthermore, the plate groove 39 is also used to connect the upper and lower sides of the collecting box 13, so that the moisture in the garbage that falls into the collecting box 13 with the garbage can drain into the cavity 11.

[0051] Working principle: When pouring the slope of the drainage ditch, farmers can select a suitable position in the middle of the drainage ditch and place the device there, and then firmly connect the device to the drainage ditch by pouring. It should be noted during installation that the installation position needs to include all the gates connected in the drainage ditch in the upstream direction of the device, so that all the water flowing through the drainage ditch must be filtered by the device. The height of the shell 1 of the device is set to be slightly higher than the standard depth of the drainage ditch, so that farmers can take out the garbage collected in the device and the filtered soil through the movable door 14 during subsequent regular cleaning. Then, when the farmer opens the gate to drain, the water will pass through the through-port 2 of the device, and then drive the rotating shaft 7 to rotate through the rotating plate 15, and then the cleaning mechanism 6 and the soil filter assembly 9 will start to operate synchronously. During operation, the two will collect the garbage and soil on the upper and lower sides of the partition 35 of the collection box 13 respectively. Farmers only need to clean the collection box 13 after a long period of time, which is convenient and quick. Compared with the existing sewage net cleaning method, this method saves time and effort and is not easy to be blocked, and is highly practical.
