The water collection tank is a sealed combined box structure with a circular through hole at the top. A fixed-position water pump is located on the side of the water collection tank. Casters are located on both sides at the bottom of the frame. This utility model improves upon the original structure by placing the tilting seat between the spray pipe and the dosing tank. The bottom baffle and the cylindrical rod maintain their fixed installation positions. The support shaft and the cylindrical rod combine to form a rotatable connector, which can drive the spray pipe to swing left and right while maintaining a constant force point.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a portable agricultural spraying device, including a water storage tank 1, an inlet pipe 2 fixedly connected to the outer surface of the water storage tank 1, a recycling mechanism 3 arranged above the water storage tank 1, a conveying mechanism 4 arranged above the recycling mechanism 3, and an adjustment mechanism 5 arranged above the water storage tank 1.

[0024] The recycling mechanism 3 includes a movable top cover 301, which is movably connected to the upper surface of the water storage tank 1. A fixed top plate 302 is provided above the movable top cover 301. An annular mesh plate 303 is fixedly connected to the outer surface of the fixed top plate 302. The bottom end of the annular mesh plate 303 is fixedly connected to the movable top cover 301. When the device is used for spraying operations, rainwater flows into the water storage tank 1 after being filtered by the annular mesh plate 303 during rainy weather. The annular mesh plate 303 intercepts impurities in the rainwater, causing the impurities to adhere to the surface of the annular mesh plate 303. Under the impact of the rainwater and the action of gravity, the impurities intercepted on the surface of the annular mesh plate 303 are washed down, which can prevent the annular mesh plate 303 from becoming clogged.

[0025] The conveying mechanism 4 includes a water pump 401, which is fixedly installed on the upper surface of the fixed top plate 302. A water delivery pipe 402 is fixedly connected to the outer surface of the water pump 401. One end of the water delivery pipe 402 away from the water pump 401 extends to the bottom of the fixed top plate 302. The water inlet end of the water pump 401 is fixedly connected to the water outlet end of the water delivery pipe 402. A plate-type water distribution pipe 403 is provided above the water pump 401. A telescopic water delivery hose 404 is fixedly connected to one side of the plate-type water distribution pipe 403. The water inlet of the plate-type water distribution pipe 403 is... The outlet end of the telescopic water supply hose 404 is fixedly connected to the end of the pump. The side of the telescopic water supply hose 404 away from the plate-type water distribution pipe 403 is fixedly connected to the water pump 401. The inlet end of the telescopic water supply hose 404 is fixedly connected to the outlet end of the water pump 401. A spray nozzle 405 is provided on one side of the plate-type water distribution pipe 403. The inlet end of the spray nozzle 405 is fixedly connected to the outlet end of the plate-type water distribution pipe 403. The adjusting mechanism 5 includes a drive motor 501, which is fixedly installed on the upper surface of the water pump 401. A drive shaft 502 is fixedly connected to the transmission end away from the water pump 401. A hydraulic cylinder 503 is fixedly connected to the end of the drive shaft 502 away from the drive motor 501. A push rod 504 is fixedly connected to the transmission end of the hydraulic cylinder 503 away from the drive shaft 502. The end of the push rod 504 away from the hydraulic cylinder 503 is fixedly connected to the plate-type water distribution pipe 403. When agricultural irrigation is required, the water pump 401 operates, causing the water stored in the water storage tank 1 to enter the telescopic water delivery hose 404 and the plate-type water distribution pipe sequentially through the water delivery pipe 402. The water is sprayed through the nozzle 405 into the pipe 403. The drive motor 501 drives the drive shaft 502 to rotate, thereby rotating the plate-type water distribution pipe 403 at a certain angle to achieve wide-range spraying. The hydraulic cylinder 503 pushes the plate-type water distribution pipe 403, and in conjunction with the drive motor 501, adjusts the agricultural spraying range to meet the agricultural spraying needs. When the water storage tank 1 is insufficient, the valve of the inlet pipe 2 can be opened to input external water sources to ensure the stable operation of agricultural spraying.

[0026] In this embodiment, a portable agricultural spraying device is used. When spraying, rainwater in rainy weather flows into the water storage tank 1 after being filtered by the annular mesh plate 303. The annular mesh plate 303 traps impurities in the rainwater, causing them to adhere to its surface. Under the impact of the rainwater and gravity, the trapped impurities are washed off the surface of the annular mesh plate 303, preventing clogging. When agricultural spraying is needed, the water pump 401 operates, causing the water stored in the water storage tank 1 to enter the telescopic water conveyor through the water delivery pipe 402. The water is sprayed through pipe 404 and plate-type water distribution pipe 403, and then sprayed out through spray nozzle 405. The drive motor 501 drives the drive shaft 502 to rotate, thereby driving the plate-type water distribution pipe 403 to rotate a certain angle to achieve range spraying. The hydraulic cylinder 503 works to push the plate-type water distribution pipe 403. With the drive of the drive motor 501, the spraying range of agriculture is adjusted to meet the spraying needs of agriculture. When the water storage tank 1 is not full, the valve of the inlet pipe 2 can be opened to input external water source to ensure the stable operation of agricultural spraying. Similarly, the same steps are used to spray pesticides on plants.
