Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a folding sprayer frame for a sprayer. Background Technology

[0002] A sprayer is a mechanical device used in agricultural production to spray pesticides, fertilizers, and other liquids. Its purpose is to prevent and control crop diseases and pests by evenly spraying the pesticides, promoting healthy crop growth, and improving agricultural production efficiency and yield. The folding sprayer frame, a key component of the sprayer, consists of a foldable support structure. Its function is to support and extend the spraying arm during operation, flexibly adjusting the spraying range and height according to different farmland terrains, crop types, and planting scales. This meets the needs of large-area, high-efficiency spraying while also allowing for convenient folding and storage when not in use, reducing the equipment's space requirements and facilitating transportation and storage.

[0003] The folding sprayer frame used in a spraying machine consists of a support and connection section and a spraying section. The support and connection section includes a fixed frame, support rods, connecting shafts and bushings, and hinge seats. The fixed frame is the basic support structure of the folding sprayer frame. The support rods are used to enhance the stability and strength of the structure and to assist in supporting the weight of the sprayer frame in its unfolded and working states. The connecting shafts and bushings are used to connect different rods or components. The hinge seats are used to connect with other components by hinge, allowing the components to rotate around the hinge point. The folding drive component is a cylinder or hydraulic cylinder that provides power through the extension and retraction of the piston to push or pull the relevant components of the sprayer frame to achieve folding and unfolding.

[0004] In existing technologies, some folding sprayers are disassembled from sprayers using bolts. However, because the working environment of sprayers is harsh, bolts are easily rusted and corroded when exposed to moisture and pesticide solutions for a long time, causing them to jam with nuts or the sprayer connection and become difficult to loosen. Therefore, a folding sprayer for sprayers is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a folding spray frame for a sprayer. The aim is to improve the existing technology that uses bolts for disassembly. However, because the working environment of a sprayer is relatively harsh, the bolts are exposed to humid environments and liquid pesticides for a long time, which can easily cause them to rust and corrode, leading to jamming with the nut or the connection part of the sprayer and making them difficult to loosen.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A folding sprayer frame for a sprayer includes a base plate. A first fixed shell is fixedly connected to the left side of the base plate. A second fixed shell is fixedly connected to the front side of the first fixed shell. A hydraulic cylinder is fixedly connected to the inner front wall of the second fixed shell. A push block is fixedly connected to the drive end of the hydraulic cylinder. A moving plate is fixedly connected to the top of the push block. A push rod is fixedly connected to the rear side of the push block. A rotating plate is fixedly connected to the rear side of the push rod. A limit block is fixedly connected to the rear side of the moving plate. A disengagement component for quickly disengaging from the folded state is fixedly connected to the top of the base plate.

[0008] As a further description of the above technical solution:

[0009] The unfolding assembly includes a fixing plate 1, the bottom of which is fixedly connected to the top of the base plate. A fixing rod is fixedly connected to the front side of the fixing plate 1. An inner shell is slidably connected to the outside of the fixing rod. A movable ring is slidably connected to the outside of the inner shell. A limit ball is slidably connected to the inside of the fixing rod. A fixing ring is fixedly connected to the outside of the inner shell.

[0010] As a further description of the above technical solution:

[0011] The bottom of the push block is slidably connected to a guide plate, and the bottom of the guide plate is fixedly connected to the bottom inner wall of the fixed shell 2.

[0012] As a further description of the above technical solution:

[0013] The bottom of the rotating plate is fixedly connected to a rotating shaft, and the bottom of the rotating shaft is rotatably connected to the bottom inner wall of the fixed shell 2.

[0014] As a further description of the above technical solution:

[0015] A spring is slidably connected to the outside of the inner shell, and the front side of the spring is fixedly connected to the rear side of the fixing ring.

[0016] As a further description of the above technical solution:

[0017] A second fixing plate is fixedly connected to the rear side of the inner shell, a first fixing bracket is fixedly connected to the front side of the second fixing plate, and a second fixing bracket is rotatably connected to the left side of the first fixing bracket.

[0018] As a further description of the above technical solution:

[0019] A lifting assembly is fixedly connected to the top of the fixed shell, and a fixing block is fixedly connected to the inner wall of the fixed shell. The outer side of the limiting block is slidably connected to the inner wall of the fixing block.

[0020] As a further description of the above technical solution:

[0021] The movable plate is externally slidably connected to the left inner wall of the first fixed shell, and the movable plate is externally slidably connected to the right inner wall of the second fixed shell.

[0022] The beneficial effects of this utility model are as follows:

[0023] (1) This utility model uses a hydraulic cylinder to drive the push block to move, thereby driving the moving plate to move, which in turn drives the push rod to rotate the rotating plate, thereby moving the moving plate on the other side and detaching it from the fixed block, thus realizing the quick installation of the spraying rack. In addition, it is convenient for transportation and storage. After disassembly, the overall volume can be reduced, thereby improving transportation efficiency and saving storage space.

[0024] (2) This utility model moves by moving the ring, thereby squeezing the spring, thereby removing the limit ball and causing the fixing rod to detach from the inner shell, thereby realizing the rapid unfolding of the folding sprayer. In addition, it significantly improves the work preparation efficiency, can quickly unfold the folding sprayer, and thus allow the sprayer to be put into work quickly, reducing auxiliary time and improving the overall spraying efficiency.

[0025] In summary, this utility model has advantages such as rapid deployment and rapid installation. Attached Figure Description

A fixing shell 2 is fixedly connected to the left side of the base plate 1, and a fixing shell 3 is fixedly connected to the front side of the fixing shell 2. Both fixing shells 2 and 3 are components used to fix the device. A hydraulic cylinder 4 is fixedly connected to the inner front wall of the fixing shell 3. The hydraulic cylinder 4 is the drive source for the mounting assembly, thereby driving the entire mounting assembly to operate.

The limit block 9 limits the object, thereby fixing it on the equipment.

[0034] Example 2

[0035] Reference Figure 2 and Figure 4The unfolding assembly includes a fixing plate 12, the bottom of which is fixedly connected to the top of the base plate 1. The fixing plate 12 is a component fixed to the base plate 1 and is the basic component of the entire unfolding assembly. A fixing rod 13 is fixedly connected to the front side of the fixing plate 12. An inner shell 14 is slidably connected to the outside of the fixing rod 13. A moving ring 15 is slidably connected to the outside of the inner shell 14. A limiting ball 16 is slidably connected inside the fixing rod 13. A fixing ring 18 is fixedly connected to the outside of the inner shell 14. The fixing rod 13 is locked inside the inner shell 14 by the limiting ball 16, thus limiting its movement. The moving ring 15 compresses the spring 17, which in turn limits the limiting ball 16 to the fixing rod 13, preventing it from moving. The fixing ring 18 provides a limiting point for the spring 17.

[0036] Example 3

[0037] Reference Figures 1 to 3 A guide plate 10 is slidably connected to the bottom of the push block 5. The bottom of the guide plate 10 is fixedly connected to the bottom inner wall of the fixed shell 3. The guide plate 10 drives the push block 5 to move linearly. A rotating shaft 11 is fixedly connected to the bottom of the rotating plate 8. The bottom of the rotating shaft 11 is rotatably connected to the bottom inner wall of the fixed shell 3. The rotating shaft 11 causes the rotating plate 8 to rotate around the rotating shaft 11. A spring 17 is slidably connected to the outside of the inner shell 14. The front side of the spring 17 is fixedly connected to the rear side of the fixed ring 18. The spring 17 drives the moving ring 15 to move. A fixed plate 19 is fixedly connected to the rear side of the inner shell 14. The fixed plate 19 connects the unfolding assembly and the fixed frame 21. The front side of the fixed plate 19 is fixedly connected to... A fixed frame 21 is connected to the device. A fixed frame 22 is rotatably connected to the left side of the fixed frame 21. Both the fixed frame 21 and the fixed frame 22 are the foundation of the spraying frame. A lifting assembly 23 is fixedly connected to the top of the fixed shell 2. The lifting assembly 23 is the foundation of the entire device, thereby driving the spraying frame to move. A fixed block 20 is fixedly connected to the inner wall of the fixed shell 2. The outer side of the limiting block 9 is slidably connected to the inner wall of the fixed block 20. The fixed block 20 is limited by the limiting block 9, thereby fixing the spraying frame to the device. The outer side of the moving plate 6 is slidably connected to the left inner wall of the fixed shell 2. The outer side of the moving plate 6 is slidably connected to the right inner wall of the fixed shell 2. The moving plate 6 receives the moving force of the pushing plate, thereby moving.

[0038] Work steps

[0039] Step 1: When the operator needs to place the sprayer frame on the sprayer, first fix the right side of the second fixed shell 3 to the left side of the first fixed shell 2. At this time, the hydraulic cylinder 4 inside the second fixed shell 3 drives the push block 5 to move, thereby moving the moving plate 6. Then the push rod 7 pushes the rotating plate 8 to rotate, thereby moving the other moving plate 6. The two moving plates 6 move closer to each other, thereby driving the limit block 9 to limit the fixed block 20, thus fixing the sprayer frame on the sprayer. This achieves quick installation of the sprayer frame, and also facilitates transportation and storage. After disassembly, the overall volume can be reduced, thereby improving transportation efficiency and saving storage space.

[0040] Step 2: After installation, the operator pulls the movable ring 15, causing it to disengage from the limiting ball 16 and compress the spring 17, storing elastic force. At this point, the upper part of the limiting ball 16 is unrestricted. The operator then pulls the fixing bracket 21, causing the fixing rod 13 to disengage from the inner shell 14. The operator can then release the movable ring 15, and the spring 17 releases its elastic force, causing the movable ring 15 to return to its original position. This allows for the rapid unfolding of the folding sprayer, significantly improving work preparation efficiency. The folding sprayer can be quickly unfolded, allowing the sprayer to be put into operation quickly, reducing auxiliary time and improving overall spraying efficiency.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
