Description

Technical Field

[0001] This utility model belongs to the field of high-standard farmland, and more specifically, it relates to a biological interception and purification combination device for ecological drainage ditches in high-standard farmland. Background Technology

[0002] High-standard farmland is a modern arable land that achieves stable and high yields through systematic construction, meeting comprehensive standards such as flat and fertile land, complete facilities, and strong disaster resistance. Currently, in high-standard farmland production, to reduce nitrogen and phosphorus concentrations in water bodies and control agricultural surface water pollution, aquatic plants with well-developed root systems are usually planted in the drainage ditches of farmland to biologically absorb and consume nitrogen and phosphorus substances in the water, preventing these substances from being discharged into natural water sources and causing pollution. However, in the actual agricultural drainage process of drainage ditches, crop debris and leaves float on the surface of the water. When these debris and leaves flow towards the aquatic plants, they are intercepted by the plant's network of roots, causing them to accumulate at the plant's root system and forming drainage blockages. Because the roots grow and intertwine, it is difficult to search and clean the accumulated debris in the water. In addition, since the aquatic plants are planted directly in the silt of the drainage ditch soil, it is extremely inconvenient to individually replace and cultivate dead aquatic plants.

[0011] 1. In this utility model, on the one hand, the water flowing in the drainage ditch is filtered through the permeable holes of the interception groove, and the interception groove intercepts the floating crop residues and branches in the water, preventing the crop residues and branches from flowing into the roots of aquatic plants in the planting cylinder and causing drainage blockage. On the other hand, the threaded engagement transmission mechanism formed by two sets of pulling sliders on the threaded surface of the double-threaded rod is used to make the pulling sliders drive the interception groove to rise and get out of the water through the hinged pulling rod, so that farmland maintenance personnel can clean up the intercepted crop residues and branches.

[0012] 2.

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0034] like Figures 1-8 As shown, this utility model provides a biological interception and purification combination device for high-standard farmland ecological drainage ditches, including a drainage ditch 1; a pad 3 is installed on the upper side of the drainage ditch 1 by rivets, and a beam frame 6 is welded to the front end of the pad 3; it also includes a biological purification frame 2, a column 8, and a guide rod 9; a interception groove 4 is slidably connected to the outer side of the column 8, a pull rod 7 is hinged to the upper side of the interception groove 4, and a pull slider 11 is hinged to the top of the pull rod 7; a beam frame 6 is welded to both the left and right ends of the guide rod 9, and a through hole is provided on both the left and right sides of the beam frame 6. A bidirectional threaded rod 10 is rotatably connected in the through hole of the beam frame 6, and a lifting knob 5 is welded to both the left and right ends of the bidirectional threaded rod 10; the biological purification frame 2 includes a planting cylinder 201 and an installation support plate 202; the installation support plate 202 is screwed to the outer side of the planting cylinder 201, and a pad 3 is bolted to the lower side of the installation support plate 202.

[0035] In this embodiment of the utility model, the interception groove 4 is a groove structure with openings on the front and upper sides. The rear side of the groove structure of the interception groove 4 is densely covered with water-permeable holes. The water flowing into the interception groove 4 flows to the placement area of ​​the biological purification rack 2 through the water-permeable holes. The crop fragments and branches are intercepted in the interception groove 4, which prevents the crop fragments and branches from entangled and accumulating inside the roots of aquatic plants and difficult to remove, and prevents drainage ditch blockage. Near the rear end of the groove structure of the interception groove 4, there are two sets of ear plates. Each set of ear plates has a circular through hole that runs vertically through the center.

[0036] In this embodiment of the utility model, there are two sets of pulling sliders 11, which are symmetrically distributed left and right. Each set of pulling sliders 11 has a through hole structure that runs left and right near the top and a threaded through hole structure that runs left and right near the bottom. The forward threaded end of the outer side of the bidirectional threaded rod 10 is engaged with the threaded through hole of the left pulling slider 11, and the reverse threaded end of the outer side of the bidirectional threaded rod 10 is engaged with the threaded through hole of the right pulling slider 11. The guide rod 9 is inserted through... Inside the through-hole structure of the pull slider 11, as the lifting knob 5 drives the bidirectional threaded rod 10 to rotate, the bidirectional threaded rod 10 drives the two sets of pull sliders 11 to move horizontally in opposite directions along the guide rod 9. The two sets of pull sliders 11 respectively pull the interception grooves 4, which are hinged at the bottom of the two sets of pull rods 7, to move upward along the column 8, so that the interception grooves 4 move the crop debris accumulated in the groove structure to the outside of the drainage ditch for centralized and unified cleaning, avoiding the need to retrieve and remove crop debris and branches from the water, making the cleaning operation more convenient.

[0037] In this embodiment of the utility model, there are twelve groups of planting cylinders 201. Each group of planting cylinders 201 is a cylindrical structure with an opening on the upper side. The outer side of the cylindrical structure of the planting cylinder 201 near the top is provided with a threaded structure. The outer side of the cylindrical structure of the planting cylinder 201 near the bottom is provided with ten groups of long grooves. The long grooves are arranged in a ring array around the vertical central axis of the planting cylinder 201. The bottom end of the planting cylinder 201 is provided with two groups of arc-shaped grooves. The roots of the aquatic plants planted in the planting cylinder 201 grow suspended in the water outside the planting cylinder 201 through the long grooves and arc-shaped grooves, so that the roots of the aquatic plants can fully contact the nitrogen and phosphorus substances in the water, thereby realizing the full absorption and purification of nitrogen and phosphorus substances in the drainage ditch water by the aquatic plants.

[0038] In this embodiment of the utility model, the lower side of the mounting support plate 202 is provided with twelve sets of cylindrical protrusions, and the center of the lower side of the cylindrical protrusions of the mounting support plate 202 is provided with a threaded through hole. The outer side of the planting cylinder 201 is threadedly engaged with the threaded through hole of the protrusion of the mounting support plate 202. The planting cylinder 201 can be screwed and removed in the threaded through hole of the cylindrical protrusion of the mounting support plate 202, which facilitates the quick disassembly and replacement of dead aquatic plants in the drainage ditch by farmland maintenance personnel.

[0039] In this embodiment of the utility model, the beam frame 6 is an inverted U-shaped structure. The left and right sides of the U-shaped structure of the beam frame 6 are provided with rectangular through slots. The ear plates of the intercepting slot 4 are inserted into the rectangular through slots of the beam frame 6. The left and right sides of the U-shaped structure of the beam frame 6 are provided with ear plates. The upper side of each set of ear plates is welded with a column 8. The column 8 is inserted into the circular through hole of the ear plate of the intercepting slot 4. The column 8 supports the intercepting slot 4 to move up and down stably in a horizontal posture, so as to prevent the intercepting slot 4 from flipping left and right during the lifting and lowering process of carrying crop residues and broken leaves.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In this invention, during the biological purification and impurity interception of water, the water flowing from the drainage ditch 1 passes through the interception tank 4. Water containing nitrogen and phosphorus flows through the permeable holes of the interception tank 4 to the twelve planting cylinders 201. The roots of aquatic plants growing in the long grooves of the planting cylinders 201 absorb and consume the nitrogen and phosphorus in the flowing water. Meanwhile, crop debris floating on the water surface is intercepted and accumulated in the groove structure of the interception tank 4, thus completing the purification of nitrogen and phosphorus and the interception of impurities in the drainage ditch 1. If it is necessary to drain and clean the crop debris accumulated in the interception tank 4, the lifting knob 5 is manually turned. The lifting knob 5 drives the bidirectional threaded rod 10 to rotate. Since the two sets of pulling sliders 11 are respectively meshed and connected to the positive and negative thread ends of the bidirectional threaded rod 10, the bidirectional threaded rod 10 drives the two sets of pulling sliders 11. Moving along the guide rod 9, the two sets of pulling sliders 11 drive the bottom hinged pulling rods 7 to rotate in opposite directions. The two sets of pulling rods 7 then pull the interception groove 4 vertically upward along the column 8 until the interception groove 4 carrying crop residues is completely removed from the water. If it is necessary to disassemble and replace dead aquatic plants individually, the planting cylinder 201 is manually rotated. Since the outer side thread of the planting cylinder 201 is engaged with the protruding thread through hole of the mounting plate 202, the planting cylinder 201 can be unscrewed and removed from the protruding thread through hole of the mounting plate 202. Then, the new planting cylinder 201 containing healthy aquatic plants is aligned with the protruding thread through hole of the mounting plate 202, and the planting cylinder 201 is rotated in the opposite direction to make the outer side thread of the planting cylinder 201 tightly engaged with the thread of the mounting plate 202, thus completing the replacement and installation of a single planting cylinder 201.

[0042] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient specifications of all components are based on their own technology; any method that achieves the desired effect can be implemented. The lifting knob 5 mentioned above is a common component on the market; upon purchase and use, simply connect it according to the instruction manual purchased with the product, and therefore will not be elaborated upon further.

[0043] The technical solution of this utility model is not limited to the scope of the embodiments of this utility model. All technical contents not described in detail in this utility model are known technologies.
