Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a height-adjustable plant protection machine mixing tank installation structure. Background Technology

[0002] During the growth process, crops need to be sprayed with pesticides and fertilized to improve their growth rate and yield. Self-propelled plant protection machines are important agricultural machinery for improving the efficiency of spraying, fertilizing, and pest control. Typically, self-propelled plant protection machines are equipped with a pesticide tank and a mixing tank to mix water, fertilizer, and pesticides in the correct proportions.

[0003] Because self-propelled plant protection machines need to avoid crops during their growing season, their vehicle height is usually over two meters. Adding water to the pesticide tank requires a special water truck, and pesticides and water-soluble fertilizers need to be manually added to the mixing tank to mix with the water in the pesticide tank. When changing fertilizers, people need to climb onto the vehicle to add the pesticides to the mixing tank. This is not only inefficient and labor-intensive, but also poses certain dangers. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a height-adjustable pesticide mixing tank installation structure for plant protection machines. This allows the height of the mixing tank to be adjusted vertically, eliminating the need for manual labor to climb onto the vehicle frame when adding pesticides, thereby improving pesticide application efficiency, reducing labor intensity, and enhancing the safety of the pesticide application process. This effectively solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable pesticide mixing box installation structure for a plant protection machine, comprising a frame, a connecting rod fixing plate on one side of the frame, an upper connecting rod and a lower connecting rod respectively provided on the connecting rod fixing plate, the upper connecting rod and the lower connecting rod being parallel, one end of the upper connecting rod and the lower connecting rod being rotatably connected to the connecting rod fixing plate by a pin, the other end of the upper connecting rod and the lower connecting rod being connected to a vertical rod by a pin, one side of the vertical rod being integrally connected to a pesticide mixing box fixing frame, a pesticide mixing box being fixed on the pesticide mixing box fixing frame, an electric actuator fixing plate being provided at the upper end of the frame, one side of the electric actuator fixing plate being connected to the fixed end of the electric actuator, and the telescopic end of the electric actuator being connected to the upper connecting rod.

[0006] As a preferred technical solution of this utility model, the mixing box fixing frame is provided with a clamp, and the mixing box is fixed on the mixing box fixing frame by the clamp.

[0007] In a preferred embodiment of this invention, the telescopic end of the electric actuator is connected to the upper connecting rod via a pin.

[0008] In a preferred embodiment of this invention, both the connecting rod fixing plate and the electric push rod fixing plate are connected to the vehicle frame by welding.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The installation structure of the pesticide mixing box of this height-adjustable plant protection machine is reasonably designed and ingeniously conceived. By setting two parallel upper and lower connecting rods that are rotatably connected to the frame, the mixing box is kept horizontal through the upper and lower connecting rods. When pesticide needs to be added, the upper connecting rod is rotated by controlling the electric actuator, and the lower connecting rod rotates synchronously with the upper connecting rod, so that the height of the mixing box decreases without changing the angle. This makes it convenient for the staff to add pesticide to the mixing box, greatly improving the convenience of use and ensuring the safety of the pesticide addition process.

[0015] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 3 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a height-adjustable pesticide mixing tank installation structure for a plant protection machine, including a frame 1. A connecting rod fixing plate 2 is provided on one side of the frame 1. An upper connecting rod 5 and a lower connecting rod 6 are respectively provided on the connecting rod fixing plate 2. The upper connecting rod 5 is located above the lower connecting rod 6 and the two are parallel. One end of the upper connecting rod 5 and the lower connecting rod 6 are rotatably connected to the connecting rod fixing plate 2 by a pin. The other end of the upper connecting rod 5 and the lower connecting rod 6 are connected to a vertical rod 9 by a pin. One side of the vertical rod 9 is integrally connected to the pesticide mixing tank fixing frame 8. A mixing tank 7 is fixed on the fixed frame 8. An electric push rod fixing plate 3 is set on the upper end of the frame 1. One side of the electric push rod fixing plate 3 is connected to the fixed end of the electric push rod 4. The telescopic end of the electric push rod 4 is connected to the upper connecting rod 5 by a pin. The installation angle of the electric push rod 4 and the position of the hole on the connecting rod fixing plate 2 ensure that the mixing tank 7 is horizontal under normal conditions. The height adjustment of the mixing tank 7 is controlled by the telescopic movement of the electric push rod 4, which makes it convenient for the staff to add medicine into the mixing tank 7, improves the efficiency of medicine addition, and reduces the labor intensity of the staff.

[0017] To facilitate the disassembly of the mixing box 7, a clamp 10 is provided on the mixing box fixing frame 8, and the mixing box 7 is fixed on the mixing box fixing frame 8 by the clamp 10.

[0018] To ensure the strength of this structure, both the connecting rod fixing plate 2 and the electric actuator fixing plate 3 are connected to the frame 1 by welding.

[0019] When the vehicle is moving, the electric actuator 4 is in a retracted state to avoid crops, and the mixing tank 7 is at a high and horizontal position. When the vehicle stops and needs to be refilled, the electric actuator 4 is energized, and the telescopic end of the electric actuator 4 extends, causing the upper connecting rod 5 to rotate around the connecting rod fixing plate 2. The movement trajectory of the lower connecting rod 6 is consistent with that of the upper connecting rod 5. The angle of the mixing tank 7 remains unchanged, and the height decreases to the manual operation position. The worker performs the refilling operation. After the refilling is completed, the electric actuator 4 is energized to retract, and the mixing tank 7 rises to its original position.

[0020] This utility model uses a planar four-bar linkage structure to ensure that the mixing tank 7 always remains horizontal when it is raised or lowered, which is convenient for workers to add medicine. The height of the mixing tank 7 is controlled by the electric push rod 4, which allows the mixing operation to be carried out at any time, avoiding frequent manual getting on and off the vehicle, improving the mixing efficiency, reducing the labor intensity of workers, and ensuring the safety of use.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
