Technical Field

[0001] This utility model relates to the field of agricultural sprayers, specifically an agricultural sprayer. Background Technology

[0002] An agricultural sprayer is a machine that disperses liquid into a mist. It is mainly used in the agricultural field and belongs to the category of plant protection machinery. It is divided into agricultural, medical and other uses, among which agricultural sprayers have a wide range of applications in agricultural production.

[0003] Existing farmland sprayers spray pesticides onto crops using a handheld sprayer boom, but these sprayers still have the following problems during use:

[0004] Existing agricultural sprayers require manual operation of the spray boom to spray pesticides on crops. Due to the limited length of the spray boom, operators need to walk on the farmland, which can easily trample on the crops. In addition, when the farmland area is large, it is difficult to control the uniform spraying of pesticides, resulting in poor operability. Therefore, it is necessary to develop an agricultural sprayer that can be used in the existing agricultural spraying field. Utility Model Content

[0005] To address the shortcomings of existing technologies, conventional agricultural sprayers require manual operation of the spray boom to spray pesticides on crops. Due to the limited length of the spray boom, operators must walk on the field to operate the sprayer, which can easily trample on the crops. Furthermore, in large fields, it is difficult to control the uniform spraying of pesticides, resulting in poor operability. This utility model proposes an agricultural sprayer.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an agricultural sprayer, comprising:

[0031] The following is in conjunction with the appendix Figure 1 —5 provides further detailed information about this application.

[0032] This application discloses an agricultural sprayer. (Refer to...) Figure 1 and Figure 3 as well as Figure 4 An agricultural sprayer includes a tractor 10, on which a liquid storage tank 11 is fixedly mounted. A traction mechanism 22 is mounted on the liquid storage tank 11. The traction mechanism 22 includes a connecting block 2200, which is fixedly mounted on the liquid storage tank 11. An assembly block 2201 is fixedly mounted on the top of the connecting block 2200. Guide openings 2202 are symmetrically provided through the assembly block 2201. Guide rods 2203 are symmetrically fixedly mounted on each guide opening 2202. Movable blocks 2204 are movably mounted on each of the two guide rods 2203. Inverted L-shaped fasteners are fixedly mounted on each movable block 2204. Fixed block 2205, the inverted L-shaped fixed block 2205 is located on one side of assembly block 2201. Spray mechanism 21 is mounted on the inverted L-shaped fixed block 2205. Spray mechanism 21 includes pump 2100 and connecting pipe 2104. Two connecting pipes 2104 are fixedly assembled with the inverted L-shaped fixed block 2205, and one end of the connecting pipe 2104 is close to the inverted L-shaped fixed block 2205. Multiple conveying branch pipes 2105 are fixedly mounted on the bottom of each connecting pipe 2104. Spray head 2106 is fixedly mounted on the bottom of each conveying branch pipe 2105. Valves 2107 are mounted on each spray head 2106.

[0033] In this invention, the tractor 10 is pushed to move on the field ridge, and the movable block 2204 moves on the guide rod 2203, so that the movable block 2204 drives the connecting pipe 2104 on the inverted L-shaped fixed block 2205 to move, so that the spray head 2106 on the delivery branch pipe 2105 is positioned above the planting field, and the corresponding valve 2107 is opened, so that the spray head 2106 with the valve 2107 opened is positioned within the planting field area. Pesticides can be sprayed on crops through the spray head 2106 on the delivery branch pipe 2105. The pesticides are sprayed evenly, avoiding manual handling. At the same time, the operator does not need to walk on the planting field, thus improving the protection of crops.

[0034] Reference Figure 4 and Figure 5An operating block 2207 is fixedly mounted on the assembly block 2201. The operating block 2207 is located between two guide ports 2202. A rotating cavity 2211 is provided inside the operating block 2207. Moving ports 2212 communicating with the rotating cavity 2211 are provided on both symmetrical sides of the operating block 2207. An operating motor 2210 is fixedly mounted on the end face of the operating block 2207. A transmission screw 2213 is fixedly mounted on the output end of the operating motor 2210. The transmission screw 2213 movably passes through the rotating cavity 2202. In the moving cavity 2211, a threaded sleeve 2214 is threadedly fitted on the transmission screw 2213. A traction block 2215 that moves in the moving port 2212 is symmetrically fixedly fitted on the threaded sleeve 2214. A fixing plate 2208 is fixedly fitted on the end face of each traction block 2215. A mounting plate 2206 is fixedly fitted on the end face of each movable block 2204. An adjusting rod 2209 is movably fitted on each mounting plate 2206. One end of the adjusting rod 2209 is movably fitted to the fixing plate 2208.

[0035] In this invention, the operating motor 2210 is started, causing the transmission screw 2213 to rotate in the threaded sleeve 2214, which in turn causes the traction block 2215 to move on the two moving ports 2212. Under the action of the adjusting rod 2209, the two movable blocks 2204 move in opposite directions on the guide rod 2203.

[0036] Reference Figure 1 - Figure 3 A threaded injection pipe 12 is fixedly mounted on the storage tank 11, and a threaded cap 13 is threadedly mounted on the threaded injection pipe 12. A support frame 20 is fixedly mounted on the traction trolley 10, and a pump 2100 is fixedly mounted on the support frame 20. A water suction pipe 2101 is fixedly mounted on the pump 2100, and one end of the water suction pipe 2101 extends into the interior of the storage tank 11. A water delivery pipe 2102 is fixedly mounted on the pump 2100, and a telescopic plastic hose 2103 is symmetrically fixedly mounted on one end of the water delivery pipe 2102. One end of the telescopic plastic hose 2103 is fixedly mounted to the connecting pipe 2104.

[0037] In this invention, the threaded cap 13 is unscrewed to allow pesticide and water to be poured into the storage tank 11, diluting the pesticide concentration. The pump 2100 is then started to extract the diluted pesticide solution from the storage tank 11, which is then transported through the water supply pipe 2102 to two telescopic plastic hoses 2103. The diluted pesticide solution in the telescopic plastic hoses 2103 is then transported to the connecting pipe 2104, and then through the connecting pipe 2104 to the delivery branch pipes 2105, so that the spray head 2106 sprays the diluted pesticide solution.

[0038] Working principle: Unscrew the threaded cap 13 to pour pesticide and water into the storage tank 11, diluting the pesticide concentration. Depending on the size of the planting field, start the operating motor 2210, causing the transmission screw 2213 to rotate in the threaded sleeve 2214. This moves the traction block 2215 across the two moving ports 2212. Under the action of the adjusting rod 2209, the two movable blocks 2204 move in opposite directions on the guide rod 2203. The movable blocks 2204 drive the connecting pipe 2104 on the inverted L-shaped fixed block 2205 to move, facilitating the positioning of the spray head 2106 on the delivery branch pipe 2105 above the planting field, and opening the corresponding valve 21. 07, so that the spray head 2106 with valve 2107 is positioned within the planting field area, push the tractor 10 to move on the field ridge, and at the same time start the pump 2100, so that the pump 2100 draws out the pesticide dilution from the storage tank 11, and then delivers it through the water delivery pipe 2102 to the two telescopic plastic hoses 2103. The pesticide dilution in the telescopic plastic hoses 2103 is delivered to the connecting pipe 2104, and then delivered to the delivery branch pipes 2105 through the connecting pipes 2104, so that the spray head 2106 sprays the pesticide dilution evenly, avoiding manual handling, and the operator does not need to walk on the planting field, thus improving the protection of crops.
