Description

Technical Field

[0001] This utility model relates to a sprayer, specifically a suspended high-range sprayer. Background Technology

[0002] A sprayer used for spraying pesticides on orchard trees includes a frame, a pesticide tank, a transmission mechanism, a spraying mechanism, and an air delivery mechanism. The spraying mechanism includes a pesticide pump that pumps the pesticide solution from the tank to the fan; the transmission mechanism transmits power to drive the pesticide pump and the fan. The fan in the air delivery mechanism includes a housing with an air inlet and an air outlet. The housing is generally fixed to the frame and cannot move, resulting in a essentially fixed position for the air outlet, making it impossible to adapt to the target. For example, when the target is short, it is impossible to spray the lower part of the target; when the target is tall, it is impossible to spray the upper part of the target, resulting in a low effective adhesion rate of the sprayed pesticide.

[0003] Although some sprayers can be repositioned, the entire fan and other components move together, resulting in higher energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a suspended high-range sprayer that can adaptively adjust the angle of the fan housing according to the height of the target, effectively spraying the entire target. It is easy to adjust, has low energy consumption, and can efficiently control pests and diseases on the entire tree.

[0005] A suspended high-range sprayer includes a frame 1, a medicine tank 2, a transmission mechanism 3, a spraying mechanism 4, and a wind-driven mechanism 5. The wind-driven mechanism 5 includes a fan 51 with a housing 511 having an air inlet and an air outlet, an impeller 512 rotatably mounted on the housing 511, and a fan input shaft 513 for driving the impeller 512 to rotate. The spraying mechanism 4 includes a medicine pump for pumping the medicine liquid in the medicine tank 2 to the fan. The transmission mechanism is used to transmit power to drive the medicine pump and the fan input shaft 513.

[0006] The cover 511 is detachably connected to the fan input shaft 513 and is oscillatingly mounted on the fan rotating fixed support 54. The fan rotating fixed support 54 is fixed on the frame 1.

[0007] When the connection between the cover 511 and the fan rotating fixed support 54 is loosened, the cover 511 can swing around the center line, thereby adjusting the position of the air outlet on the cover 511; when the cover 511 and the fan rotating fixed support 54 are fixedly connected, the position of the air outlet on the cover 511 remains unchanged.

[0008] As a further improvement to the aforementioned suspended high-range sprayer, a high-range air guide shroud 55 and a low-range air guide shroud 56 are connected in parallel at the air outlet of the housing 511; the outlet cross-sectional area of ​​the high-range air guide shroud 55 is smaller, while the outlet cross-sectional area of ​​the low-range air guide shroud 56 is larger; a nozzle 48 is provided at the outlet of both the high-range air guide shroud 55 and the low-range air guide shroud 56; the nozzle 48 is connected to the liquid pump through a pipeline.

[0011] As a further improvement to the aforementioned suspended high-range sprayer, a fan rotation adjustment handle 53 is fixed on the casing.

[0012] As a further improvement to the aforementioned suspended high-range sprayer, the air delivery mechanism 5 has two or more connected in series, with two or more fan input shafts 513 coaxially connected, and each housing 511 is detachably mounted on a fan rotation fixed support 54.

[0013] As a further improvement to the aforementioned suspended high-range sprayer, the fan 51 is a centrifugal fan or an axial flow fan.

[0014] As a further improvement to the aforementioned suspended high-range sprayer, the transmission mechanism 3 includes a universal drive shaft 31, a gearbox 32, a main pulley 33, a synchronous belt 34, a pump pulley 35, a bearing housing 36, a driven pulley 37, and a blower pulley 38. One end of the transmission mechanism 3 is connected to the tractor PTO output shaft via the universal drive shaft 31, which provides power to the suspended high-range sprayer. The other end of the universal drive shaft 31 is connected to the gearbox 32. The main pulley 33 is installed on the input shaft side of the gearbox 32 and connected to the pump pulley 35 via the synchronous belt 34 to provide power to the liquid pump. The gearbox 32 is fixed on the frame body 11. The driven pulley 37 is installed at the end of the output shaft of the gearbox 32 and connected to the blower pulley 38 fixed on the blower input shaft via the synchronous belt 34 to provide power for the blower rotation.

[0015] As a further improvement to the aforementioned suspended high-range sprayer, the spraying mechanism 4 includes an inlet pipe 41, a filter 42, a plunger pump 43, an outlet pipe 44, a return pipe 45, a solenoid valve 46, a distribution pipe 47, and a nozzle 48. The inlet pipe 41, which houses the filter 42, is connected to the tank body 23 and the plunger pump 43 in the tank 2. The outlet pipe 44 of the plunger pump 43 is connected to two distribution pipes 47 and one return pipe 45 via the solenoid valve 46. The nozzle 48 at the outlet of the high-range air guide shroud 55 and the nozzle 48 at the outlet of the low-range air guide shroud 56 are each connected to a distribution pipe 47. The other end of the return pipe 45 is connected to the tank body 23.

[0016] As a further improvement to the aforementioned suspended high-range sprayer, the frame 1 includes a frame body 11 and a suspension mounting plate 12. The tractor suspension is connected to the suspension mounting plate 12 via a pin, and the sprayer as a whole adjusts its working height by following the tractor suspension.

[0017] As a further improvement to the aforementioned suspended high-range sprayer, the fan rotating fixed support 54 has an arc-shaped groove 541 with the fan input shaft as the center line. A screw 514 with a nut 515 is fixed on the cover 511, extending into the arc-shaped groove 541. When the nut 515 is loosened, the screw 514 can slide in the arc-shaped groove, and the cover 511 swings around the center line. When the nut 515 is tightened, the cover 511 is fixedly connected to the fan rotating fixed support 54, and the cover 511 cannot swing around the center line.

[0018] As a further improvement to the above-mentioned suspended high-range sprayer, the medicine tank 2 includes a medicine tank cover 22, a medicine tank body 23, a ball valve 25, and a water inlet pipe connector 26; the medicine tank body 23 is fixed on the frame, and the water outlet of the medicine tank body 23 is connected to the water inlet pipe 41 in the spraying mechanism 4 through the ball valve 25.

[0019] The beneficial effects of this utility model are:

[0020] The casing can swing to adjust the position (angle) of the air outlet. This allows for adjustment of the casing's position to accommodate different target heights, ensuring the sprayed airflow is directed at the target and the medication effectively adheres to it, avoiding medication waste. Furthermore, the casing's swing is centered on the fan input shaft, so the swing does not affect the connection between the transmission mechanism and the fan input shaft. The structure is simple, and the casing angle adjustment is convenient and quick.

[0021] The high-range and low-range air guides are connected in parallel at the air outlet of the casing. The airflow velocity from the outlet of the high-range air guide is relatively large, which can spray the higher part of the target. The airflow velocity from the outlet of the low-range air guide is relatively small, which can spray the lower part of the target. This combination of high and low airflow can effectively spray the entire target from top to bottom.

[0022] When there are two air delivery mechanisms, the two air delivery mechanisms can spray two rows of targets on both sides of the suspended high-range sprayer at the same time, doubling the work efficiency.

[0023] A single transmission mechanism transmits power to both the air delivery mechanism and the spraying mechanism, simplifying the overall structure and facilitating connection to the tractor's PTO output shaft.

[0024] The frame features a suspension mounting plate for easy connection and installation with a tractor. The tractor suspension is connected to the suspension mounting plate via pins, allowing the sprayer to adjust its working height according to the tractor suspension.

[0025] The fan rotating fixed support has an arc-shaped groove with the fan input shaft as the center line. A screw rod with a nut is fixed on the cover and extends into the arc-shaped groove. When the nut is loosened, the screw rod can slide in the arc-shaped groove and the cover swings around the center line. When the nut is tightened, the cover and the fan rotating fixed support are fixedly connected, and the cover cannot swing around the center line. Attached Figure Description
