Description

Technical Field

[0001] This utility model provides a support structure, and particularly relates to a support structure for the spray bar of an agricultural pesticide sprayer. Background Technology

[0002] In agricultural plant protection equipment, the spray boom support structure of a pesticide sprayer is a core component connecting the pesticide storage tank and the spray pipe. Through the frame's enclosure and support of the storage tank, and the extension and positioning of the boom, the spatial posture of the spray pipe is fixed, ensuring the uniformity and stability of pesticide spraying. In existing technology, a typical design for this structure is as follows: an integrated welded frame (directly welded to the outer wall of the storage tank), paired with a rigid, non-foldable support rod (welded to the side of the frame or rigidly connected by bolts). The spray pipe is fixed using ordinary metal clamps (without anti-slip design, relying solely on pre-tightened bolts to hold the spray pipe and support rod). The nozzle is directly connected to the spray pipe via a flange or ordinary threaded interface. Relying on the rigid connection chain of "frame-boom-pipe," the basic support function of the spray boom is completed.

[0003] However, the above design has multiple drawbacks: the one-piece welded frame cannot be disassembled, making it difficult to adapt to storage tanks of different volumes / shapes. Furthermore, the storage tanks are prone to deformation due to long-term pressure, leading to loose frame connections and compromising overall support stability. The rigid support rod cannot be folded, requiring additional storage space during transportation and making it difficult to store compactly when not in use, increasing logistics and storage costs. These drawbacks result in significant shortcomings in the existing spray boom support structure in terms of adaptability, storage capacity, connection reliability, and ease of maintenance, thus restricting the operating efficiency and service life of pesticide sprayers. Utility Model Content

[0004] In order to solve the above problems, this application provides a support structure for the spray bar of an agricultural pesticide sprayer, which solves the problems of poor frame adaptability, inconvenient storage of support rods, unstable connection and cumbersome maintenance of spray head.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a support structure for the spray bar of an agricultural pesticide sprayer, comprising:

[0006] Support frame: It is fitted around the outside of the medicine storage tank and is a detachable closed frame structure that surrounds the perimeter of the medicine storage tank;

[0007] Foldable support rod: symmetrically connected to both sides of the support frame, extending along the length of the medicine storage tank, and rotatably connected to the support frame through a hinge structure to achieve folding and storage within the range of 0° to 180°;

[0008] The spray nozzle is distributed parallel to the foldable support rod and is stably clamped onto the foldable support rod by a clamp-type connecting assembly.

[0009] Nozzle assembly: The nozzles are spaced apart on the spray pipe body, and are connected to the spray pipe body via a quick-connect structure. A Y-type filter structure is integrated at the inlet of the nozzle.

[0010] Preferably, the support frame is formed by bending a metal round tube and is detachably connected by a bolt assembly to form an annular support space surrounding the medicine storage tank.

[0011] Preferably, the hinge structure is a pin that runs through the support frame and the foldable support rod, and the two ends of the pin are provided with limiting springs to restrict the flipping displacement of the foldable support rod.

[0012] Preferably, the clamp-type connecting assembly includes symmetrically arranged semi-circular clamps and locking bolts. The inner wall of the semi-circular clamp is attached with an anti-slip rubber pad, and the spray pipe body and the foldable support rod are simultaneously tightened by the locking bolts.

[0013] Preferably, the Y-shaped filter structure is integrally formed with the nozzle, its filter chamber is conical, and the filter element is a detachable mesh structure.

[0014] Preferably, there are two foldable support rods, symmetrically distributed on both sides of the support frame, maintaining a parallel distance from the spray pipe body.

[0015] Preferably, the quick-connect structure between the nozzle and the spray pipe is an external threaded connector with an internal threaded interface, or a snap-fit ​​connection structure.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0017] To address the problems of unstable connection between the support and the storage tank, inconvenient storage of the spray boom, easy loosening of the spray pipe and support rod, easy clogging of the nozzle by impurities, and cumbersome disassembly and assembly in existing agricultural pesticide sprayers, this device strengthens the overall connection stability by using a detachable closed frame-shaped support frame (metal round tube bent and bolted to form a ring support space) fitted outside the storage tank; the spray boom is folded and stored by using a pin hinge structure (with a limit spring, supporting 0°~180° rotation) that runs through the support frame and the foldable support rod; the spray pipe body parallel to the support rod is fastened with a clamp-type connection component with anti-slip rubber pads (symmetrical semi-circular clamp + locking bolts) to ensure stable spacing and a firm connection; and impurities are filtered and prevented from clogging by an integrated conical cavity mesh filter element Y-type filter structure at the nozzle inlet, and the nozzle is quickly disassembled and maintained by an external thread / clamp quick-connect structure, simultaneously solving five major pain points: support, storage, connection, anti-clogging, and disassembly and assembly.

[0025] 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.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1 and Figure 2 As shown, an agricultural pesticide sprayer boom support structure includes a detachable closed frame-shaped support frame 1 fitted around the outside of the pesticide storage tank. The frame is formed by bending a metal round tube and is detachably connected via bolt assemblies to form an annular support space surrounding the pesticide storage tank. Foldable support rods 2 extending along the length of the pesticide storage tank are symmetrically connected to both sides of the support frame 1. These two rods are rotatably connected by a pin hinge structure 5 that passes through the support frame 1 and the foldable support rods 2. Limiting springs are provided at both ends of the pin to restrict the rotational displacement of the foldable support rods 2. A spray pipe body 3, distributed parallel to the foldable support rods 2, is stably clamped and fixed by a clamp-type connecting assembly 4. This assembly includes symmetrically arranged semi-circular arc clamps with anti-slip rubber pads adhered to their inner walls. Locking bolts simultaneously tighten the spray pipe body 3 and the foldable support rods 2.

[0029] In this implementation scheme, the nozzle assemblies 6, spaced apart on the spray pipe body 3, are connected to the pipe body via external threaded connectors and internal threaded interfaces or snap-fit ​​quick-connect structures. Compared to traditional flange or fixed threaded connections, the nozzles 6 can be quickly assembled and disassembled without tools, solving the problem of cumbersome and time-consuming disassembly during existing nozzle maintenance. The Y-shaped filter structure 7 integrally formed at the nozzle 6 inlet has a conical filter chamber that increases the flow of pesticide liquid and the filtration area. Combined with a detachable mesh filter element, it can effectively intercept particulate impurities in pesticides, prevent nozzle clogging, and facilitate easy disassembly and cleaning of the filter element. This invention solves the problems of frequent clogging and difficult cleaning caused by the lack of filtration or fixed filtration structure in existing nozzles. Two foldable support rods 2 are symmetrically distributed on both sides of the support frame 1, maintaining a parallel distance with the spray pipe body 3. This symmetrical support on both sides enhances the deformation resistance of the spray pipe body 3, avoiding the tilting of the pipe body caused by unilateral support, and ensures the parallelism between the spray pipe body 3 and the support rods 2. This ensures that the spray range of each nozzle 6 is uniform and consistent, solving the problems of spray pipe body tilting and spray range deviation caused by insufficient number or asymmetrical distribution of existing support rods.

[0030] like Figure 3 and Figure 4 As shown, nozzle assemblies 6 are spaced apart on the spray pipe body 3. The nozzles 6 are connected to the spray pipe body 3 through external threaded joints and internal threaded interfaces or snap-fit ​​quick-connect structures. A Y-shaped filter structure 7 is integrated at the inlet of the nozzle 6. Its filter chamber is conical and the filter core is a detachable mesh structure. There are two foldable support rods 2, which are symmetrically distributed on both sides of the support frame 1 and maintain a parallel distance from the spray pipe body 3.

[0031] In this implementation scheme, the nozzle assemblies 6, spaced apart on the spray pipe body 3, are connected to the pipe body via external threaded connectors and internal threaded interfaces or snap-fit ​​quick-connect structures. Compared to traditional flange or fixed threaded connections, the nozzles 6 can be quickly assembled and disassembled without tools, solving the problem of cumbersome and time-consuming disassembly during existing nozzle maintenance.

This invention solves the problems of frequent clogging and difficult cleaning caused by the lack of filtration or fixed filtration structure in existing nozzles. Two foldable support rods 2 are symmetrically distributed on both sides of the support frame 1, maintaining a parallel distance with the spray pipe body 3. This symmetrical support on both sides enhances the deformation resistance of the spray pipe body 3, avoiding the tilting of the pipe body caused by unilateral support, and ensures the parallelism between the spray pipe body 3 and the support rods 2. This ensures that the spray range of each nozzle 6 is uniform and consistent, solving the problems of spray pipe body tilting and spray range deviation caused by insufficient number or asymmetrical distribution of existing support rods.

[0032] In actual use, this device requires the use of existing technologies such as a medicine storage tank (positioned via the annular space of the support frame 1), a medicine delivery power device (such as a manual pump or electric plunger pump, connected to the spray pipe 3 via a hose to provide medicine pressure), an inlet valve (located in the connecting pipe between the medicine storage tank and the spray pipe 3, used to control the flow of medicine), and a backpack strap (detachably connected to the support frame 1 for easy carrying by the operator); the metal round tubes of the support frame 1 and the foldable support rod 2 can be made of galvanized steel pipe or 6061 aluminum alloy pipe (combining strength and durability). (Corrosive), the semi-circular clamp of the clamp-type connecting component 4 can be made of Q235 carbon structural steel (with enhanced rust resistance through surface galvanizing), the anti-slip rubber pad is made of nitrile rubber (resistant to pesticide corrosion and with a high coefficient of friction), the spray pipe body 3 is made of PVC reinforced hose or polyethylene (PE) pipe (good flexibility and anti-aging), and the mesh filter core of the Y-type filter structure 7 is specifically a 304 stainless steel filter screen (pore size 80-120 mesh, balancing filtration efficiency and liquid flow). By combining these existing devices and technologies with the above material selection, a complete pesticide spraying operation system is formed.

[0033] Specifically, when installing this device, first place the medicine storage tank on a horizontal platform. Loosen the bolt assembly of the support frame 1 with a wrench, fit it to the preset height of the medicine storage tank, and then tighten the bolts to fix the frame and the medicine storage tank. Next, rotate the foldable support rod 2 around the pin of the hinge structure 5 until it is parallel to the length direction of the medicine storage tank. Lock the position using the limit spring, and then fix the spray pipe 3 to the support rod 2 using the locking bolts of the clamp-type connecting assembly 4. During this process, the parallelism between the spray pipe 3 and the support rod 2 should be calibrated using a spirit level. In use, connect the output end of the electric plunger pump (as in the prior art) to the input end of the spray pipe 3 through a high-pressure resistant rubber hose. The outlet of the medicine storage tank is connected to the input end of the plunger pump via a ball valve. After the operator carries the medicine storage tank on their back, they open the ball valve and start the plunger pump. The medicine is delivered to each nozzle assembly 6 through the spray pipe 3, filtered by the Y-type filter structure 7, and then sprayed out from the nozzle. After the operation is completed, the ball valve and the plunger pump are closed, the clamp-type connection assembly 4 is loosened to remove the spray pipe 3, the quick-connect structure of the nozzle 6 is disassembled for cleaning, the limit spring is loosened to fold the foldable support rod 2 close to the side wall of the medicine storage tank, and finally the bolt assembly of the support frame 1 is loosened to complete the overall disassembly and storage of the device. The whole process does not require special tools and is compatible with most existing backpack medicine storage tanks with a volume of 10-30L.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
