Description

Technical Field

[0001] This solution belongs to the field of pesticide spraying, specifically involving a pesticide sprayer for grassland pest and disease control with multi-layer filtration function. Background Technology

[0002] Grasslands are a type of vegetation dominated by herbaceous plants, distributed across all continents. They are a type of land cover and a multifunctional natural complex, encompassing various types such as tropical grasslands and temperate grasslands. Grassland management often involves controlling grassland pests and diseases, which necessitates the application of pesticides.

[0003] A search revealed a utility model patent application with publication number CN217547087U, which discloses a spraying device for controlling poisonous weeds in grasslands. This device belongs to the field of pesticide spraying technology and includes a base plate with multiple wheels at its bottom. A push handle, a battery, a pesticide tank, and a water pump are fixedly connected to the top of the base plate. The water pump's inlet pipe is connected to the outlet at the bottom of the pesticide tank's outer wall via a conduit. A water injection pipe is installed through the top of the pesticide tank. The water pump's outlet pipe is connected to a flexible hose via a solenoid valve, and a nozzle is connected to the outlet end of the flexible hose.

[0004] In existing technologies, when spraying pesticides for pest and disease control on grasslands, the failure to filter and remove impurities from the water and pesticides added to the pesticide cartridge can cause impurities in the water and pesticides to mix inside the cartridge before being sprayed through the nozzle, leading to clogging of the nozzle. Furthermore, the failure to filter the pesticide liquid entering the water pump and nozzle from the pesticide cartridge can cause scale and impurities adhering to the inner wall of the cartridge to enter the water pump and nozzle, causing wear inside the water pump and clogging of the nozzle, thus affecting the smooth spraying of pesticides during the control of grassland pests and diseases. Utility Model Content

[0005] The purpose of this solution is to provide a grassland pest and disease control sprayer with multi-layer filtration function to solve the problem that existing technologies fail to filter and remove impurities from the water and pesticides entering the spray cylinder. It also solves the problem that scale and impurities on the inner wall of the spray cylinder can easily wear down the water pump and clog the spray plate.

[0006] To achieve the above objectives, this solution provides a grassland pest and disease control sprayer with multi-layer filtration function, including a movable base. A pesticide cylinder is mounted on the top of the movable base. A first motor is mounted in the middle of the top of the pesticide cylinder, and an inlet pipe is connected to one side of its top. A dosing funnel is vertically connected to the surface of the inlet pipe. A first filtration mechanism is mounted in the middle of the inlet pipe. The first filtration mechanism includes a filter box. A first support column is fixed to the bottom of the filter box. A first cover plate is bolted to the top of the filter box. A rotating rod rotatably passes through one end of the filter box. A filter frame is fixed to the surface of the rotating rod. A second motor is mounted on the top of the rotating rod. The second motor is fixedly installed on the first... At the top of the cover plate, a first mounting frame is tightly inserted into the other end of the filter box. A first filter screen is connected in the middle of the first mounting frame. A second cover plate, which is sealed and attached to the top of the first cover plate, is fixed at the top of the first mounting frame. A slag trough is opened at the bottom of the filter box and in front of the first filter screen. A connecting ring is fixed at the bottom of the filter box and outside the bottom of the slag trough. A receiving cylinder is tightly connected to the outer side of the connecting ring by threads. A vertical rod is fixed at the top of the inside of the receiving cylinder. An intercepting cover is fixed at the top of the vertical rod. A water pump is installed at the bottom of the outer side of the reagent cylinder. A second filtration mechanism is connected between the water pump and one side bottom of the reagent cylinder. The second filtration mechanism includes a second filter screen.

[0007] The principle of this solution is as follows: During use, the inlet end of the liquid inlet pipe is connected to an external water source, water is added to the chemical cylinder, and simultaneously, the chemical is poured in through the dosing funnel. Both water and chemical flow through the liquid inlet pipe, first entering the filter box. Firstly, a second motor drives the rotating rod and filter frame to rotate. The rotating filter frame agitates the flowing water and chemical, improving the mixing degree between them. The rotating filter frame also traps and intercepts long, thin impurities mixed in the water and chemical, performing a first filtration. Afterward, the water and chemical flow to the first filter screen, where particulate matter and other impurities are filtered out. The filtered particles and impurities fall downward into the receiving cylinder. Impurities accumulating inside the receiving cylinder are blocked by an intercepting hood, reducing their impact on the filter. The upward floating mechanism reduces clogging of the first filter screen. Furthermore, the threaded connection between the receiving cylinder and the connecting ring facilitates disassembly, installation, and cleaning of accumulated impurities. The first cover can be opened to clean the inside of the filter box, as well as the filter frame and the first filter screen, improving the filtration performance of water and chemicals. Next, water and chemicals enter the chemical cylinder and are mixed by the stirring structure driven by the first motor. Finally, the water pump draws the chemical liquid from the chemical cylinder and sprays it onto the grassland from the spray plate for pest and disease control. During the process of the chemical liquid passing from the chemical cylinder through the second flange joint and the first flange joint into the water pump, it is filtered and impurities removed by the second filter screen, preventing scale and other impurities from entering the water pump and spray plate, thus avoiding pump wear and spray plate clogging.

[0008] The technical advantages of this solution are as follows: by setting up a first filtration mechanism, long strip-shaped impurities in the water and chemicals are wrapped and filtered by a rotating filter frame. Particulate impurities are filtered out through the first filter screen, keeping clean water and chemicals to enter the chemical cylinder for mixing and use. Furthermore, the chemical liquid entering the water pump and spray plate is filtered through a second filter screen to remove scale and other impurities, keeping the spray plate unobstructed for spraying the chemical liquid.

[0009] Furthermore, a liquid outlet pipe is connected to the top of the water pump, and a spray plate is installed at the top of the liquid outlet pipe. The spray plate is used to spray pesticides onto the grassland.

[0010] Furthermore, the spray plate is horizontally installed on top of the water pump, and second support columns are fixed between its two bottom ends and the movable base. The second support columns provide stable support for the spray plate.

[0011] Furthermore, a first flange joint is fixed to one side of the water pump, and a sealing ring is adhered to the outer side of the first flange joint. The sealing ring is used to seal the connection between the first flange joint and the second flange joint to prevent water leakage.

[0012] Furthermore, a second flange joint is fixed to one bottom end of the reagent cartridge, and the second flange joint is fastened to the first flange joint by bolts. The first and second flange joints are used for disassembling, installing, and cleaning the second filter screen.

[0013] Furthermore, the sealing ring is tightly clamped between the first flange joint and the second flange joint, and the second filter screen abuts against the port of the first flange joint and is tightly fitted inside the sealing ring. The sealing ring and the second filter screen are provided to seal and prevent leakage during installation.

[0014] Furthermore, the water pump is bolted to the movable base, and the first flange joint and the second flange joint are horizontally aligned. The first and second flange joints facilitate the installation and removal of the water pump. Attached Figure Description

[0024] The specific implementation process of this utility model is as follows: In use, the inlet end of the liquid inlet pipe 7 is connected to an external water source, water is added to the inside of the agent cylinder 2, and at the same time, the agent is poured in from the dosing funnel 8. Both water and agent flow through the liquid inlet pipe 7 and first enter the filter box 13. First, the second motor 10 drives the rotating rod 16 and the filter frame 17 to rotate. The rotating filter frame 17 rotates and stirs the flowing water and agent, improving the mixing degree between the water and agent. The rotating filter frame 17 also wraps around and intercepts long strip-shaped impurities mixed in the water and agent, performing a first filtration of the water and agent. After that, the water and agent flow to the first filter screen 19, where the first filter screen 19 filters out particles and other impurities in the water and agent. The filtered particles and other impurities fall downward through the slag trough 18 into the receiving cylinder 14.

Furthermore, the receiving cylinder 14, through its threaded connection with the connecting ring 21, facilitates disassembly, installation, and cleaning of accumulated impurities. The first cover plate 12 can be opened to clean the inside of the filter box 13, and to clean and maintain the filter frame 17 and the first filter screen 19, improving the filtration performance of water and chemicals. Next, water and chemicals enter the chemical cylinder 2, where they are mixed by the stirring structure driven by the first motor 9. Finally, the water pump 3 draws the chemical liquid from the chemical cylinder 2 and sprays it onto the grassland from the spray plate 4 for pest and disease control. During the process of the chemical liquid entering the water pump 3 from the chemical cylinder 2 through the second flange joint 24 and the first flange joint 25, it is filtered and impurities removed by the second filter screen 27, preventing scale and other impurities from entering the water pump 3 and the spray plate 4, thus avoiding wear on the water pump 3 and clogging of the spray plate 4.

[0025] This solution uses a first filtration mechanism to filter long, thin impurities in the water and chemicals by rotating the filter frame 17. Particulate impurities are filtered out by the first filter screen 19, ensuring that clean water and chemicals enter the chemical cylinder 2 for mixing. The second filter screen 27 filters out scale and other impurities from the chemical liquid entering the water pump 3 and spray plate 4, ensuring that the spray plate 4 can spray the chemical liquid smoothly.
