Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, specifically a portable pesticide mixing and spraying device. Background Technology

[0002] A sprayer is an agricultural machine that disperses liquids. It is a type of agricultural spraying machine, a plant protection machine in agricultural machinery, and belongs to portable agricultural machinery. It is also called a tall crop sprayer or a field bath sprayer. Sprayers are suitable for pest and disease control in forests, nurseries, orchards, tea gardens, field crops such as cotton, wheat, rice, and corn, as well as large areas of grassland. They are also suitable for pest and disease control in urban and suburban gardens, vegetable gardens, and greenhouses.

[0003] While existing backpack-style pesticide sprayers are convenient for spraying, their weight can cause shoulder discomfort and make them inconvenient to carry. Furthermore, after the pesticide is mixed and poured into the pesticide tank, it is usually dissolved by hand shaking, which leads to uneven dissolution and low dissolution efficiency. To address these issues, we propose a portable pesticide mixing and spraying device. Utility Model Content

[0024] like Figure 1-4As shown, this utility model provides a technical solution: a portable pesticide mixing and spraying device, including a pesticide box 1. A feeding pipe is fixedly connected to the top of the pesticide box 1 near the right side. A sealing cap 2 is fitted onto the feeding pipe, and the outer wall of the feeding pipe and the inner wall of the sealing cap 2 are both provided with matching threads. A water pump 15 is fixedly connected to the lower left wall of the pesticide box 1. An L-shaped conduit 14 is fixedly connected to the bottom of the water pump 15. The other end of the L-shaped conduit 14 passes through the outer wall of the pesticide box 1 and communicates with its interior. A hose 7 is fixedly connected to the top of the water pump 15. A spray bar 5 is fixedly connected to the other end of the hose 7. A nozzle 4 is fixedly connected to the other end of the spray bar 5. A rotating tube 19 is movably connected to the bottom of the inner cavity of the pesticide box 1 near the left side via a bearing. A wire is installed inside the rotating tube 19. The rod 18 and the inner wall of the rotating tube 19 are fixedly connected to a slider that matches the lead screw 18. Several evenly distributed stirring blades 20 are fixedly connected to the outer wall of the rotating tube 19. The top of the inner cavity of the pesticide box 1 is provided with a through hole that matches the lead screw 18. The top of the lead screw 18 extends through the through hole to the top of the pesticide box 1 and is fixedly connected with a pull ring 3. A limit tube 16 is fixedly connected to the top of the inner cavity of the pesticide box 1 near the through hole. Limit blocks 17 are fixedly connected to the upper side walls of both sides of the lead screw 18. The inner wall of the limit tube 16 is provided with a limit groove that matches the limit block 17. The front wall of the pesticide box 1 is an inwardly concave arc shape. An arc plate 8 is fixedly connected to the front wall of the pesticide box 1 through a connecting rod. Several evenly distributed heat dissipation holes are provided on the front wall of the arc plate 8.

[0025] The shoulder strap 6 allows the device to be carried when the pesticide tank 1 is empty, making it more convenient to use during spraying operations. The rollers 12 allow the device to be moved by pulling out the movable rod 10 and handle 9 when the pesticide tank 1 is full of pesticides and heavy, making the device easy to carry and less likely to cause injury to the shoulders and waist due to prolonged heavy pressure.

[0026] like Figure 1-4 As shown, shoulder straps 6 are fixedly connected to the front wall of the pesticide box 1 near the left and right sides, and the shoulder straps 6 are covered with sponge pads. A battery 13 is fixedly connected to the rear wall of the pesticide box 1 near the bottom. Fixing strips 11 are fixedly connected to the rear wall of the pesticide box 1 near the left and right sides. A handle 9 is provided on the rear side of the pesticide box 1 near the top. Movable rods 10 are fixedly connected to the bottom of the handle 9 near the left and right sides. The top of the fixing strip 11 has a movable hole that matches the movable rod 10. The bottom end of the movable rod 10 extends into the movable hole. A connecting block is fixedly connected to the bottom of the fixing strip 11. Rollers 12 are movably connected to the left and right side walls of the connecting block through a rotating shaft and bearings. Two arc-shaped support blocks arranged in the front and back direction are fixedly connected to the bottom of the pesticide box 1 near the left and right sides.

[0027] By cooperating with the pull ring 3 and the lead screw 18, when the pull ring 3 is pulled, causing the lead screw 18 to move vertically, the slider on the inner wall of the rotating tube 19 moves on the lead screw 18, causing the rotating tube 19 to rotate. This, in turn, causes the stirring blades 20 to rotate, agitating the material. This effectively improves the dissolution efficiency of pesticides inside the device and ensures the dissolution effect.

[0028] Working principle: When using this technical solution, first rotate to open the sealing cover 2, and pour water and pesticide into the pesticide tank 1 according to a certain ratio. Pull the pull ring 3 to drive the screw 18 to move back and forth in the up and down direction. When the screw 18 moves up and down, it drives the rotating tube 19 to rotate in the forward and reverse direction at high speed through the slider, which in turn drives the stirring blade 20 to stir the material, effectively ensuring the dissolution effect and improving the dissolution efficiency. After the pesticide is loaded and stirred evenly, the pesticide tank 1, which rotates slowly for a long time, may cause shoulder discomfort. At this time, the handle 9 can be pulled out and the device can be moved through the roller 12, making it more convenient to carry. When spraying, the device can be worn with the shoulder strap 6. The heat dissipation effect is effectively improved by the arc plate 8 and the heat dissipation holes on it.
