Description

Technical Field

[0001] This utility model relates to the field of fertilizer suction pipe technology for fertilizer applicators, and in particular to a filter structure for a fertilizer suction pipe of a fertilizer applicator for wheat fields to prevent clogging. Background Technology

[0002] A wheat field fertilizer applicator is an agricultural machine used for precision fertilization, widely applied in modern agriculture to improve fertilization efficiency and accuracy. Through this machine, fertilizer can be evenly distributed to every corner of the field, reducing fertilizer waste, increasing crop yield, and minimizing negative environmental impact. Equipped with a precision control system, the fertilizer applicator can automatically adjust the amount and method of fertilizer application based on soil needs and crop growth status, thereby optimizing crop growth conditions.

[0003] Traditional fertilizer suction pipes typically consist of a suction pipe, a filter, and connecting components. The suction pipe draws fertilizer from the fertilizer source, the filter prevents solid impurities from entering the pipe and protects the system from blockages, and the connecting components connect the suction pipe to other parts of the fertilizer applicator to ensure smooth and stable fertilizer delivery.

[0004] Traditional fertilizer suction pipes are prone to clogging, usually due to improper filter design or the presence of large particles in the fertilizer. When the fertilizer contains a large amount of solid particles or impurities, the filter cannot effectively remove these debris, leading to pipe blockage. Furthermore, factors such as the pipe's inner diameter and excessively strong or weak suction can also cause uneven fertilizer flow, further exacerbating the clogging. Clogging not only affects fertilization effectiveness and causes uneven fertilizer distribution, but also damages other components of the fertilization system, increases maintenance costs, and causes interruptions in fertilization operations, reducing production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fertilizer suction pipe filter structure for a wheat field anti-clogging fertilizer applicator, which aims to improve the problems of traditional fertilizer suction pipes being prone to clogging, increasing maintenance costs, causing interruptions in fertilization operations, and reducing production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fertilizer suction pipe filter structure for a wheat field anti-clogging fertilizer applicator, comprising a pipe body, a side pipe fixedly connected to the side wall of the pipe body, a filter screen provided inside the side pipe, multiple slots provided inside the filter screen, and a disassembly assembly provided on the outer wall of the side pipe. The assembly / disassembly assembly includes multiple connecting plates, the sidewalls of which are fixedly connected to the outer wall of the side tube. Each connecting plate has a connecting column rotatably connected inside. The outer wall of the connecting column is fixedly connected to a connecting frame. The bottom of the connecting frame is fixedly connected to a positioning plate, which engages with the slot. A top plate one is fixedly connected to the top of the connecting column, and a top plate two is fixedly connected to the top of the connecting plate. Multiple springs one are provided between the top plate one and the top plate two. Both ends of each spring one are fixedly connected to the top plate one and the inside of the spring one, respectively. A fertilizer conveying assembly is provided at the top of the tube.

[0007] As a further description of the above technical solution: The fertilizer delivery assembly includes an output pipe, the two ends of which are fixedly connected to the top of the pipe body.

[0008] As a further description of the above technical solution: The output pipe is provided with a connecting pipe on its side wall, and a sleeve is fixedly connected to one end of the connecting pipe.

[0009] As a further description of the above technical solution: A fixing pipe is fixedly connected to the side wall of the output pipe, and a fixing column is fixedly connected to the side wall of the fixing pipe.

[0010] As a further description of the above technical solution: The outer wall of the fixed column is rotatably connected to multiple rotating shafts, and each rotating shaft is fixedly connected to an operating plate on its side wall.

[0011] As a further description of the above technical solution: A locking plate is fixedly connected to the side wall of the control panel, and the locking plate is engaged with the limiting groove.

[0012] As a further description of the above technical solution: Each of the operating panels is provided with a second spring at its bottom. One end of the second spring is fixedly connected to the bottom of the operating panel, and the other end of the second spring is fixedly connected to the outer wall of the fixed column.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the filter screen can be quickly removed for cleaning or replacement by disassembling the components, reducing the tedious process of manual maintenance. Combined with the anti-clogging structure, it reduces the accumulation of impurities, lowers the maintenance frequency, thereby saving labor costs and extending the service life of the fertilizer suction pipe.

[0014] 2. In this utility model, the operating plate on the fixed column, under the elastic force of the second spring, drives the clamping plate to engage with the limiting groove of the sleeve, ensuring a stable connection between the connecting pipe and the sleeve. This prevents fertilizer leakage or unstable flow due to loosening during fertilizer delivery. When the pipeline needs to be disassembled, pressing the operating plate compresses the second spring, causing the clamping plate to disengage from the limiting groove, achieving rapid separation. This ensures a continuous and stable fertilizer delivery process and reduces the risk of blockage caused by connection problems. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a fertilizer suction pipe filter structure for a wheat field anti-clogging fertilizer applicator, including a pipe body 1. The pipe body 1 is made of PVC with a smooth inner wall and is used to transport filtered fertilizer, providing a stable flow channel to avoid interruption of fertilizer suction due to obstruction during the transport process, thus ensuring the continuity of fertilization. This is common knowledge and will not be elaborated further here. A side pipe 2 is fixedly connected to the side wall of the pipe body 1. A filter screen 3 is provided inside the side pipe 2. The filter screen 3 is made of stainless steel woven mesh and is used to intercept impurities such as soil particles and straw fragments in the fertilizer, preventing impurities from entering the pipe body 1 and causing pipe blockage, thus ensuring the smooth flow of the fertilizer suction pipe. Multiple slots 4 are opened inside the filter screen 3, and a disassembly and assembly component is provided on the outer wall of the side pipe 2. The assembly / disassembly unit includes multiple connecting plates 5, whose sidewalls are fixedly connected to the outer wall of the side tube 2. Each connecting plate 5 has a rotatably connected connecting post 6 inside. The connecting post 6 rotates in conjunction with the connecting plate 5, thereby causing the connecting frame 7 to swing up and down, providing power for the engagement or disengagement of the positioning plate 8 and the slot 4. The connecting frame 7 is fixedly connected to the outer wall of the connecting post 6, and the connecting frame 7 transmits the rotational power of the connecting post 6 to the positioning plate 8, enabling the positioning plate 8 to accurately align with the slot 4. The bottom of the connecting frame 7 is fixedly connected to the positioning plate 8, which aligns with the slot 4. The four-phase engagement is achieved by fixing a top plate 9 to the top of the connecting column 6 and a top plate 10 to the top of the connecting plate 5. Multiple springs 11 are installed between the top plate 9 and the top plate 10. The springs 11 are carbon steel compression springs, which push the top plate 9 with their own elasticity, causing the connecting column 6 to rotate the connecting frame 7 downwards, thereby allowing the positioning plate 8 to tightly engage with the slot 4. This is common knowledge and will not be elaborated further here. Both ends of each spring 11 are fixedly connected to the top plate 9 and the inside of the spring 11. A fertilizer conveying assembly is installed at the top of the pipe body 1.

[0019] Reference Figure 4 and Figure 5The fertilizer delivery assembly includes an output pipe 12, with both ends of the output pipe 12 fixedly connected to the top of the pipe body 1. A connecting pipe 13 is provided on the side wall of the output pipe 12, and a sleeve 14 is fixedly connected to one end of the connecting pipe 13. The sleeve 14 engages with an external fertilizer pipeline and, through a limiting groove 15 and a clamping plate 20, secures the connecting pipe 13 to the output pipe 12, preventing pipeline separation due to pressure during fertilizer delivery. A fixing pipe 16 is fixedly connected to the side wall of the output pipe 12. The fixing pipe 16 is used to fix a fixing post 17 to the side wall of the output pipe 12, providing an installation foundation for the fixing post 17 and ensuring the structural stability of the fixing post 17 and subsequent components. A fixed column 17 is fixedly connected to the side wall of the fixed tube 16. Multiple rotating shafts 18 are rotatably connected to the outer wall of the fixed column 17. The rotating shafts 18 rotate in coordination with the fixed column 17, thereby driving the operating plate 19 to swing up and down, providing power for the engagement or disengagement of the locking plate 20 and the limiting groove 15. An operating plate 19 is fixedly connected to the side wall of each rotating shaft 18. A locking plate 20 is fixedly connected to the side wall of the operating plate 19. The locking plate 20 engages with the limiting groove 15. A second spring 21 is provided at the bottom of each operating plate 19. One end of the second spring 21 is fixedly connected to the bottom of the operating plate 19, and the other end of the second spring 21 is fixedly connected to the outer wall of the fixed column 17.

[0020] Working principle: The filter screen 3 inside the side tube 2 filters out soil particles, straw fragments, etc., from the fertilizer, preventing impurities from entering the tube body 1 and causing blockage, thus ensuring unobstructed fertilizer absorption. The connecting column 6 on the connecting plate 5 can rotate, driving the connecting frame 7 and the bottom positioning plate 8 to move. When the positioning plate 8 engages with the slot 4 of the filter screen 3, the spring 11 between the top plate 1 9 and the top plate 2 10 is in an extended state. Through the elastic force, the positioning plate 8 is pushed to tightly engage with the slot 4, firmly fixing the filter screen 3. When the filter screen 3 needs to be cleaned or replaced, the connecting frame 7 is rotated to compress the spring 11, and the positioning plate 8 is disengaged from the slot 4, allowing the filter screen 3 to be removed. To solve the problem of cumbersome disassembly of traditional filters, the output pipe 12 guides the fertilizer filtered by the filter screen 3 to the connecting pipe 13, and then conveys it to the external fertilizer applicator through the sleeve 14. Under the elastic force of the second spring 21, the operating plate 19 on the fixed column 17 drives the clamping plate 20 to engage with the limiting groove 15 of the sleeve 14, ensuring a stable connection between the connecting pipe 13 and the sleeve 14 and preventing fertilizer leakage or unstable flow due to loosening during fertilizer delivery. When the pipeline needs to be separated, pressing the operating plate 19 compresses the second spring 21, and the clamping plate 20 disengages from the limiting groove 15, achieving rapid separation and ensuring continuous and stable fertilizer delivery, reducing the risk of blockage caused by connection problems.
