Description

Technical Field

[0001] This utility model relates to the field of crop control device technology, specifically to an insecticidal spray bracket. Background Technology

[0002] A backpack manual sprayer is a portable, human-powered agricultural spraying device, mainly used for crop pest and disease control, public facility disinfection, and greening spraying. It is suitable for farmland, orchards, greenhouses, and other similar environments. Its main components include a pesticide tank, spray boom, and carrying strap system.

[0003] Shoulder-mounted manual sprayers are widely used due to their low cost and flexibility. Operators must carry the spray tank on their backs, using one hand to operate a pressure lever to maintain liquid pressure, and the other hand to hold the spray nozzle and continuously swing it to evenly spray the liquid onto the crops. This method has significant drawbacks such as high labor intensity and low spraying efficiency. Patent CN207400257U discloses a pesticide application device for pest and disease control. This device features an independent walking support with motor-driven wheels and a motor-driven swing mechanism, designed to achieve automatic swinging of the spray nozzle and reduce the burden on operators.

[0004] However, the structural features of this device limit its practicality: 1. The structure is complex and the manufacturing cost is high, making it difficult for ordinary farmers to accept and resulting in poor economic efficiency; 2. It relies on external power and has poor environmental adaptability. In working environments such as fields and greenhouses where there is often a lack of stable power supply, the equipment cannot work properly. 3. Overall bulkiness, lack of portability and flexibility: The added metal frame, motor, battery, and other components significantly increase the overall weight and size of the equipment. This makes turning and moving difficult in confined spaces like greenhouses or on uneven terrain, negating the fundamental advantage of backpack sprayers: flexibility. Utility Model Content

[0005] This utility model addresses the aforementioned shortcomings of the existing technology by providing an insecticidal spray holder. To achieve the above objective, this utility model provides the following technical solution: An insecticide spray holder for a shoulder-mounted sprayer includes a support rod connected to a medicine tank, one end of which is vertically connected to a rotatable swing arm.

Users do not need to perform any professional maintenance. It is sturdy, durable, and has a long service life.

[0012] 4. Ensure uniform and consistent spraying: The locking mechanism fixes the swing arm at the optimal angle and height, ensuring that the nozzle maintains a stable spraying posture and height throughout the operation. This ensures uniform and consistent spraying of rows of crops, avoiding uneven spraying caused by fatigue during manual operation and significantly improving the control effect.

[0013] 5. Significantly improves operational safety: By fixing the spray boom to the front end of the bracket and adjusting the telescopic rod, a safe distance is maintained between the spray head and the operator, effectively avoiding the risk of pesticides drifting in the wind and directly contacting the operator's skin and respiratory tract, reducing the chance of pesticide poisoning and protecting personnel health.

[0014] 6. Flexible adjustment and strong adaptability: The telescopic design of the support rod allows for flexible adjustment of the distance between the nozzle and the operator to adapt to different working spaces. The multi-angle locking function of the swing arm allows users to quickly adjust the spraying position according to the crop height, enabling targeted spraying of different parts of the crop (such as the leaf surface and leaf underside).

[0015] 7. Portability and ease of operation: The stand can be quickly connected or disconnected from any existing shoulder-mounted sprayer without affecting the portability of the sprayer itself. The operation is simple and intuitive, requiring no training and conforming to farmers' usage habits. Attached Figure Description

One end of the support sleeve 201 is inserted with the telescopic rod 204. The distance between the swing rod 3 and the medicine box 1 can be adjusted by sliding the telescopic rod 204. When in use, the distance between the swing rod 3 and the medicine box 1 can be adjusted according to the spraying space (the farther the distance from the medicine box 1, the safer it is for personnel). The side wall of the support sleeve 201 is provided with locking bolts 202 for fixing the telescopic rod 204. The telescopic rod 204 has a limiting groove 203 on its side wall that cooperates with the locking bolt 202, which can prevent the telescopic rod 204 from being pulled out of the support sleeve 201. The end of the telescopic rod 204 is provided with a positioning plate 205, and the side wall of the positioning plate 205 is provided with a lock hole 206. One end of the swing rod 3 is connected to the positioning plate 205 through a rotating shaft. The locking rod 5 is located on one side of the swing rod 3, and one end of the locking rod 5 is provided with a locking block 502 that cooperates with the lock hole 206. like Figure 3 , Figure 4 , Figure 5 As shown, a guide sleeve 301 is provided on the side wall of the rocker arm 3, and the locking rod 5 is slidably engaged with the guide sleeve 301. A push block 501 is provided at the end of the locking rod 5 away from the locking block 502. A positioning sleeve 303 is provided on the side wall of the rocker arm 3, and a spring 302 connected to the push block 501 is fixed inside the positioning sleeve 303. The spring 302 pushes the locking rod 5 to slide towards the positioning plate 205.

[0020] There are multiple keyholes 206, which can fix the rocker arm 3 at different angles.

[0021] For ease of operation, the length of the locking rod 5 shall not be less than the width of the medicine box 1.
