Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, and in particular to a suspended liquid fertilizer atomizing spraying arm and its orchard fertilization machine. Background Technology

[0002] Agricultural machinery, with its low cost, high efficiency, and automation, plays a vital role in agricultural development. To improve the efficiency of diversified fertilization, batch fertilization using spray arms is one approach.

[0003] A search revealed a prior art dual-pipe cantilever fertilization system for sprinkler irrigation (publication number: CN214708744U), comprising a cantilever and irrigation nozzles mounted on a water supply pipeline. The fertilizer tank is fixed to the central cantilever by stainless steel straps. The fertilizer outlet of the fertilizer tank is connected to a filter and a proportioning fertilizer applicator. The proportioning fertilizer applicator is connected to the main fertilization pipeline via a fertilizer solution pump. The main fertilization pipeline is fixed to the cantilever by a support pipe welded to it and clamps. The main fertilization pipeline is connected to the water supply pipeline through the cantilever outlet. A tee is installed on the main fertilization pipeline, with an external threaded hose connector connected to the tee. A φ12 hose is connected below the external threaded hose connector, and an internal threaded hose connector and fertilizer nozzles are connected below the φ12 hose.

[0004] In existing technologies, the main method involves installing pipes on the cantilever and securing them with wire. During fertilization, the pipes may become twisted and deviated due to the high-pressure liquid flow. At this time, the nozzles mounted on the pipes will change the direction of fertilization due to the pipe deviation, causing fertilizer to drift to parts outside the fruit trees, affecting the quality of fertilization and increasing losses. There is room for optimization.

[0005] Therefore, we propose a suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator. Utility Model Content

[0006] This invention mainly addresses the technical problem that the nozzles may affect fertilizer spraying due to pipe twisting, and provides a suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a suspended liquid fertilizer atomizing spraying arm, comprising:

[0008] The boom and the nozzle are mounted on one side of the boom and have several branch pipes fixedly installed on them.

[0009] A support structure is provided on one side of the boom to support the nozzle. The support structure includes a support plate and a reinforcing rod. Several support plates are fixedly installed on the side wall of the boom, and a reinforcing rod is fixedly installed between two adjacent support plates. The branch pipe is inserted into the reinforcing rod.

[0010] A limiting component is installed on the support plate to lock the nozzle. The limiting component includes a limiting frame and a stop block. A limiting frame is provided on the top of each support plate. The limiting frame is detachably connected to the support plate. The stop block is fixedly connected to the limiting frame. The stop block can press down on the nozzle to limit and fix the nozzle.

[0011] In a preferred embodiment of this utility model, the pallet is formed into a rectangular plate, the end of the pallet is welded and fixed to the side wall of the upper arm, the reinforcing rod extends obliquely between the two pallets, and the two ends of the reinforcing rod are respectively fixedly connected to the two pallets.

[0012] In a preferred embodiment of this utility model, the reinforcing rod is provided with a positioning hole, and the branch pipe is inserted into the positioning hole.

[0013] In a preferred embodiment of this utility model, the limiting frame is a rectangular block with a through mounting hole at the top and a threaded hole at the top of the support plate. A screw is installed in the mounting hole, and the screw is fastened to the threaded hole to lock and fix the limiting frame.

[0014] In a preferred embodiment of this utility model, the stop block forms an arc-shaped plate, the end of the stop block is fixedly connected to the top surface of the limiting frame, the concave surface of the stop block faces the support plate, and the nozzle is limited at the concave surface of the stop block.

[0015] In a preferred embodiment of this utility model, the limiting component further includes a connecting rod, which is fixedly connected to the limiting frame.

The arm is locked and fixed to the tractor unit by bolts, and the output port of the water pump is connected to the spray pipe through a hose.

[0018] Beneficial effects

[0019] This utility model provides a suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator. It has the following beneficial effects:

[0020] 1. This suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer achieve initial positioning and fixation of the spraying pipe by placing the spraying pipe on the support plate and inserting the branch pipe into the positioning hole. At this time, the branch pipe and reinforcing rod on the wall of the spraying pipe are connected to suppress the rolling of the spraying pipe in the circumferential direction, ensuring the stability of the spraying process. Secondly, after the branch pipe is inserted into the positioning hole, the position of the branch pipe will not shift, and the spraying angle can also be controlled. Multiple support plates are set on one side of the arm, and adjacent support plates are connected by reinforcing rods to form a whole, which also increases the overall strength of the arm and makes it less likely to bend and deform excessively due to gravity during fertilization.

[0021] 2. This suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator, in order to limit and lock the spray pipe, uses screws to lock the limiting frame and the support plate. The arc-shaped stop can press down on the spray pipe to limit it. At this time, the spray pipe will not shake, further improving the stability of the spray pipe after installation. When installing the spray pipe, it is only necessary to lock multiple limiting frames with the corresponding support plates. It is easy to disassemble and assemble, and convenient for later replacement and maintenance.

[0022] 3. This suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator, by setting connecting rods, uses multiple connecting rods to connect multiple limiting frames into a whole. During installation, multiple stops are simply placed on the spray pipe so that the limiting frame and the support plate are locked in one-to-one correspondence, reducing the probability of losing a single limiting frame during disassembly and assembly, and ensuring the integrity of multiple limiting frames in limiting the spray pipe.

[0023] 4. The suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator have rubber pads. The pads with anti-slip grooves abut against the outer wall of the spray pipe, and the stop blocks apply pressure to the pads. The pads can fit against the outer wall of the spray pipe, suppressing the shaking and deviation of the spray pipe, and further improving the limiting effect of the spray pipe.

[0031] A suspended liquid fertilizer atomizing spraying arm and its orchard fertilizer applicator, such as Figure 1 and Figure 2 As shown, it includes:

[0032] The boom 10 and the nozzle 11 are mounted on one side of the boom 10 and several branch pipes 12 are fixedly installed on the nozzle 11.

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a support structure is set on one side of the boom 10 to support the nozzle 11. The support structure includes a support plate 13 and a reinforcing rod 14. Several support plates 13 are fixedly installed on the side wall of the boom 10. A reinforcing rod 14 is fixedly installed between two adjacent support plates 13. The branch pipe 12 is inserted into the reinforcing rod 14. The support plate 13 forms a rectangular plate. The end of the support plate 13 is welded and fixed to the side wall of the boom 10. The reinforcing rod 14 extends obliquely between two support plates 13. The two ends of the reinforcing rod 14 are fixedly connected to the two support plates 13 respectively. The reinforcing rod 14 is provided with a positioning hole 15. The branch pipe 12 is inserted into the positioning hole 15.

[0034] In this scheme, the nozzle 11 is placed on the support plate 13 and the branch pipe 12 is inserted into the positioning hole 15 to achieve initial positioning and fixation of the nozzle 11. At this time, the branch pipe 12 and the reinforcing rod 14 on the wall of the nozzle 11 are connected, which can suppress the rolling of the nozzle 11 in the circumferential direction and ensure the stability of the spraying process. Secondly, after the branch pipe 12 is connected to the positioning hole 15, the position of the branch pipe 12 will not shift, and the spraying angle can also be controlled. Multiple support plates 13 are set on one side of the boom 10, and adjacent support plates 13 are connected by reinforcing rods 14 to form a whole. The overall strength of the boom 10 is also higher, and it is not easy to bend and deform excessively due to gravity during the fertilization process.

[0035] like Figure 4 and Figure 6As shown, a limiting assembly is installed on the support plate 13 to lock the nozzle 11. The limiting assembly includes a limiting frame 20 and a stop block 22. A limiting frame 20 is provided on the top of each support plate 13. The limiting frame 20 is detachably connected to the support plate 13. The stop block 22 is fixedly connected to the limiting frame 20. The stop block 22 can press down on the nozzle 11 to limit and fix the nozzle 11. The limiting frame 20 is a rectangular block. The top of the limiting frame 20 has a through-hole. The top of the support plate 13 has a threaded hole. A screw is provided in the mounting hole. The screw is fastened to the threaded hole to lock and fix the limiting frame 20. The stop block 22 forms an arc-shaped plate. The end of the stop block 22 is fixedly connected to the top surface of the limiting frame 20. The concave surface of the stop block 22 faces the support plate 13. The nozzle 11 is limited at the concave surface of the stop block 22.

[0036] In this solution, in order to limit and lock the nozzle 11, the limiting bracket 20 and the support plate 13 are locked with screws. The arc-shaped stop block 22 can press down on the nozzle 11 to limit it. At this time, the nozzle 11 will not shake, further improving the stability of the nozzle 11 after installation. When installing the nozzle 11, it is only necessary to lock multiple limiting brackets 20 with the corresponding support plates 13. The installation and removal are convenient and easy to replace and maintain later.

[0037] like Figure 4 As shown, the limiting assembly also includes a connecting rod 21, which is fixedly connected to the limiting frame 20. A connecting rod 21 is provided between two adjacent limiting frames 20. Multiple limiting frames 20 are connected into a whole through the connecting rod 21. By setting the connecting rod 21, multiple limiting frames 20 are connected into a whole using multiple connecting rods 21. During installation, multiple stops 22 are simply placed on the nozzle 11 so that the limiting frame 20 and the support plate 13 are locked in a one-to-one correspondence. This reduces the probability of losing a single limiting frame 20 during disassembly and assembly, and ensures the integrity of the multiple limiting frames 20 in limiting the nozzle 11.

[0038] like Figure 6 As shown, the limiting component also includes a gasket 23 and anti-slip grooves 24. The gasket 23 is fixedly connected to the stop block 22. The gasket 23 is an arc-shaped block. Several anti-slip grooves 24 are opened on the inner circumferential surface of the gasket 23. The inner circumferential surface of the gasket 23 abuts against the outer wall of the nozzle 11 and limits the nozzle 11. Specifically, the gasket 23 is a rubber block. The gasket 23 with anti-slip grooves 24 abuts against the outer wall of the nozzle 11, and the stop block 22 applies a squeezing force to the gasket 23. The gasket 23 can fit against the outer wall of the nozzle 11, suppress the shaking and displacement of the nozzle 11, and further improve the limiting effect of the nozzle 11.

[0039] As not shown in the figure, an orchard fertilizer applicator includes a tractor unit. A water tank is fixedly installed on the tractor unit, and a water pump is fixedly installed inside the water tank. All the aforementioned suspended liquid fertilizer atomizing spray arms are installed on one side of the tractor unit. The main boom 10 is locked and fixed to the tractor unit by bolts. The output port of the water pump is connected to the spray pipe 11 through a hose. The tractor unit is not shown in the figure, but can be a tractor. The water tank is filled with liquid fertilizer, which is pumped into the spray pipe 11 and discharged through various branch pipes 12. Nozzles can be installed at the ends of the branch pipes 12 to achieve fertilization of the fruit trees. Since the tractor unit and water pump are known prior art, they will not be described in detail here. By setting the aforementioned suspended liquid fertilizer atomizing spray arms, the main boom 10 is not prone to large swings during fertilization, has high strength, and is simple and quick to install the spray pipe 11, with good limiting effect for the spray pipe 11.

[0040] The working principle of this utility model is as follows: The nozzle 11 is placed on the support plate 13, and the branch pipe 12 is inserted into the positioning hole 15 to achieve initial positioning and fixation of the nozzle 11. Multiple limiting frames 20 are connected into a whole by multiple connecting rods 21. During installation, multiple stops 22 are placed on the nozzle 11 so that the limiting frame 20 and the support plate 13 correspond one-to-one. The limiting frame 20 and the support plate 13 are locked with screws. The arc-shaped stops 22 can press down on the nozzle 11. This limits the position of the nozzle 11. The gasket 23 is a rubber block. The gasket 23 with anti-slip groove 24 abuts against the outer wall of the nozzle 11, while the stop block 22 applies a squeezing force to the gasket 23. The gasket 23 can fit against the outer wall of the nozzle 11, suppressing the shaking and displacement of the nozzle 11, and realizing the installation and fixation of the nozzle 11. The liquid fertilizer is sent into the nozzle 11 by the water pump and discharged through each branch pipe 12. The nozzle can be installed at the port of the branch pipe 12, thereby realizing the fertilization of the fruit trees.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
