Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an orchard sprayer with adjustable spraying range. Background Technology

[0002] Orchard sprayers are agricultural machines specifically designed for the prevention and control of pests and diseases in fruit trees, foliar fertilization, and the spraying of growth regulators. They atomize liquid pesticides, including insecticides, fungicides, herbicides, foliar fertilizers, and growth regulators, into fine droplets and spray them evenly and effectively onto the fruit trees, including the front and back of the leaves, branches, trunks, and even parts of the ground, to achieve the purpose of preventing and controlling pests and diseases, supplementing nutrients, or regulating growth. They usually use wind-assisted spraying technology, which can effectively cover the top and inside of the canopy of large fruit trees.

[0003] Chinese patent document CN208403016U discloses an orchard sprayer, relating to the field of agricultural machinery. A high-pressure spray pump is connected to a pesticide tank via a high-pressure inlet pipe. The high-pressure spray pump is connected to a distributor and a nozzle distributor via a high-pressure outlet pipe. The nozzle distributor is connected to the nozzles and, via a return pipe, to the pesticide tank. The pesticide tank and the nozzle distributor are connected via a pesticide mixing pipe. A high-pressure hydraulic pump is connected to an oil tank via a high-pressure inlet pipe and to a hydraulic distributor via a high-pressure outlet pipe. The hydraulic distributor is connected to a hydraulic motor via a hydraulic motor inlet pipe. The hydraulic motor is connected to a blower, and the blower is connected to a ring-shaped nozzle. The hydraulic motor is connected to the oil tank via a hydraulic motor return pipe. It features a reasonable structural design, simple operation, and convenient use. Its overall structure is low-profile, compact, and flexible, facilitating easy entry and exit from orchards. The distributor facilitates easy operation, and the multi-blade blower operates at low speed, consumes little energy, produces low noise, has a large air volume, and achieves high operating efficiency and good spraying effect. The following problems exist with existing technologies:

[0004] Although the fan in the aforementioned literature can spray the atomized liquid upwards, the air inlet is located on the side and the air volume cannot be adjusted, which means that the height range of the atomized liquid cannot be adjusted, making it difficult to be compatible with fruit trees of different heights. At the same time, because the air outlet in the aforementioned literature is located at the rear and relies on the wind deflector to change the wind direction and blow upwards, and the entire water pipe is also located inside the air outlet, the wind resistance is relatively large, increasing the load and power consumption of the fan. Utility Model Content

[0005] This invention provides an orchard sprayer with adjustable spraying range to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An orchard sprayer with adjustable spraying range includes a trailer frame. A fixed base and a pesticide storage mechanism are mounted on the top of the trailer frame. A spraying mechanism is mounted on the top of the fixed base. The spraying mechanism includes a fan housing. The spraying mechanism is located at the rear of the fan housing. A fan is fixedly installed inside the fan housing. The fan drive end extends through to the left side of the fan housing and is fixedly mounted with a driven pulley.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides an orchard sprayer with adjustable spraying range. Through the cooperation of the air inlet, positioning plate, positioning threaded hole, fixing bolt, arc baffle and adjusting slide, the air volume of the fan can be manually adjusted at will, thereby controlling the amount of air output.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides an orchard sprayer with adjustable spraying range, including a trailer frame 1, which is used to tow the rear end of an agricultural tractor or other drive equipment. A fixed base frame 2 and a pesticide storage mechanism 4 are provided on the top of the trailer frame 1. A spraying mechanism 3 is provided on the top of the fixed base frame 2. The spraying mechanism 3 includes a fan housing 31, and a spraying mechanism 32 is provided on the rear side of the fan housing 31. A fan is fixedly installed in the inner cavity of the fan housing 31. The fan drive end extends through to the left side of the fan housing 31 and is fixedly installed with a driven pulley 33. An air inlet 311 is opened on the rear side of the fan housing 31, penetrating its inner cavity. Several air inlet guide plates 312 are evenly fixedly installed between the left and right sides of the inner wall of the air inlet 311. Positioning plates 313 are fixedly installed on both the left and right sides of the inner wall of the air inlet guide plates 312. Positioning plate 313 is located in front of air inlet guide plate 312. Both positioning plates 313 are provided with front and rear through positioning threaded holes 314. The inner ring of both positioning threaded holes 314 is threaded with fixing bolts 315. An arc baffle 316 is provided in front of air inlet 311. The width of arc baffle 316 is greater than that of air inlet 311. Arc baffle 316 is provided with two left and right through adjusting slide grooves 317. The two fixing bolts 315 are slidably connected to the two adjusting slide grooves 317 respectively. A vertical plate 21 is fixedly installed on the top left side of the fixed base frame 2. A servo motor 22 is fixedly installed on the right side of the vertical plate 21. The output shaft of the servo motor 22 passes through to the left side of the vertical plate 21 and is fixedly installed with a drive pulley 23. The drive pulley 23 and the outer wall of the driven pulley 33 are connected by a transmission belt 24.

[0024] The overall trailer frame 1 can be directly driven by an agricultural tractor. When in use, the servo motor 22 on one side of the start plate 21 drives the drive pulley 23 to rotate. With the transmission belt 24 and the driven pulley 33, the fan in the inner cavity of the fan box 31 can be started. The air source can be evenly introduced into the inner cavity of the fan box 31 through several air intake guide plates 312 on the inner side of the air intake hole 311. When it is necessary to adjust the air intake volume to control the spraying height range, simply loosen the fixing bolts 315 in the positioning threaded holes 314 of the two positioning plates 313 by rotating them without disassembling them. The overall arc baffle 316 can slide up and down against the front side of the air intake hole 311 by adjusting the sliding groove 317 on the outer wall of the fixing bolts 315. The air intake volume can be controlled by the blocking range of the air intake hole 311. After adjustment, tighten the two fixing bolts 315 to complete the fixation of the arc baffle 316.

[0025] like Figure 4 As shown, the spraying mechanism 32 includes a front windshield 321, which is fixedly installed on the top rear side of the fan housing 31. A gate-shaped drug delivery pipe 322 is fixedly installed on the front side of the front windshield 321, and several atomizing spray heads 323 that penetrate to the rear side of the front windshield 321 are evenly fixedly connected to the rear side of the drug delivery pipe 322. A high-pressure drug delivery pipe 324 is fixedly connected to the bottom left side of the drug delivery pipe 322. A valve 325 is provided on the outer wall of the high-pressure drug delivery pipe 324. The drug storage mechanism 4 includes a drug storage tank and a pump body. The input end of the pump body penetrates into the inner cavity of the drug storage tank, and the output end of the pump body is fixedly connected to the rear end of the high-pressure drug delivery pipe 324.

[0026] When spraying, the liquid medicine in the storage tank can be drawn out by the pump body included in the storage mechanism 4 and input into the inner cavity of the delivery pipe 322 through the high-pressure delivery pipe 324. Then, it can be atomized and sprayed out through several atomizing spray heads 323 that penetrate to the rear side of the front windshield 321. At the same time, the delivery of liquid medicine can be started and stopped at any time through the valve 325. The external installation of the delivery pipe 322 can reduce the wind resistance of the air outlet.

[0027] like Figure 5 As shown, the rear end of the fan housing 31 is fixedly connected to an air outlet pipe 318 that passes through its inner cavity. An air outlet is opened at the top of the air outlet pipe 318. The front baffle plate 321 is located in front of the air outlet pipe 318. Several air outlet guide plates 3211 are fixedly installed in a semi-circular array on the rear side of the front baffle plate 321. The several air outlet guide plates 3211 are located between several atomizing spray heads 323 and the air outlet pipe 318. The rear end of the several air outlet guide plates 3211 is fixedly installed with a rear baffle plate 3212. The rear baffle plate 3212 is fixedly connected to the rear side of the air outlet pipe 318.

[0028] The air source generated by the fan inside the fan housing 31 can be sprayed out through the air outlet 318, thereby blowing the liquid medicine generated by the upward atomizing spray head 323 upward to the top of the fruit. At the same time, the air outlet of the air outlet 318 is more concentrated by the obstruction of the rear baffle 3212 and the front baffle 321. With the help of several air outlet guide plates 3211, the air outlet is more uniform. The air source can be blown out with minimal wind resistance, reducing the load and power consumption of the fan.

[0029] The working principle of this orchard sprayer with adjustable spraying range will be explained in detail below.

[0030] like Figure 1-5As shown, the overall trailer frame 1 can be directly driven by an agricultural tractor. During use, the servo motor 22 on one side of the starter plate 21 drives the drive pulley 23 to rotate. This, combined with the transmission belt 24 and driven pulley 33, drives the fan inside the fan housing 31. Airflow enters the fan housing 31 evenly through several air intake guide plates 312 inside the air inlet 311. When adjusting the airflow to control the spray height, the fixing bolts 315 in the positioning threaded holes 314 of the two positioning plates 313 are loosened by rotating them, but not disassembled. This allows the overall arc-shaped baffle 316 to slide up and down against the front of the air inlet 311 via the adjusting groove 317, thus controlling the airflow by the area of ​​the air inlet 311 being blocked. After adjustment, the two fixing bolts 315 are tightened to complete the arc-shaped baffle 316. With the fixed 16, during spraying, the pump body included in the pesticide storage mechanism 4 can draw out the pesticide liquid from the pesticide storage tank and input it into the inner cavity of the pesticide delivery pipe 322 through the high-pressure delivery pipe 324. Then, it can be atomized and sprayed out through several atomizing spray heads 323 that penetrate to the rear side of the front windshield 321. At the same time, the delivery of pesticide liquid can be started and stopped at any time through the valve 325. The external installation of the delivery pipe 322 can reduce the wind resistance of the air outlet. Meanwhile, the air source generated by the fan in the inner cavity of the fan box 31 can be sprayed out through the air outlet pipe 318, which can blow the pesticide liquid generated by the several upward atomizing spray heads 323 upward to reach the top of the fruit. At the same time, the air outlet of the upward air outlet of the air outlet pipe 318 is more concentrated by the obstruction of the rear windshield 3212 and the front windshield 321. With the help of several air outlet guide plates 3211, the air outlet is more uniform. The air source can be blown out with minimal wind resistance, reducing the load and power consumption of the fan.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
