Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural equipment, and particularly relates to a double-wing type lightweight and efficient air-assisted orchard sprayer. Background Art

[0002] Applying pesticides in orchards can reduce most fruit losses and plays an important role in improving fruit yield and quality. The air-assisted technology is an efficient pesticide spraying technology and has been widely applied to the process of applying pesticides in orchards to improve the quality of pesticide spraying operations.

[0003] At present, new main-stem type high-density orchards are widely planted. By utilizing the apical dominance of fruit trees to increase production and improve quality, the characteristics of these fruit trees are narrow canopy and tall tree body. However, traditional air-assisted orchard sprayers have many problems. For example, some sprayers reduce the windward area by lowering the height of the spraying device to reduce the wind resistance during machine driving, but this results in a small wind speed in the upper layer area above 5 m, making the spraying effect on the top of the fruit trees poor; the structure of the spray driving device is complex. Some air-assisted sprayers use a tension pulley to control the operation of the medicine pump, resulting in low transmission efficiency of the machine, increased energy consumption, and a complex wire-pulling device structure, which increases the processing difficulty.

[0004] In order to improve the spraying effect on the top of fruit trees in main-stem type high-density orchards by air-assisted sprayers, save costs, reduce energy consumption, and simplify the structure, it is necessary to design an orchard air-assisted sprayer that can provide a high wind speed airflow in the upper layer area above 5 m and efficiently control spraying. Summary of the Invention

[0005] In view of this, the present invention provides a double-wing type lightweight and efficient air-assisted orchard sprayer. By adopting double-wing-shaped air guide plates supplemented by reasonable axial flow fans, front air guide plates, and rear air guide plate height dimensions, the lateral output wind speed at the top is increased, while materials are saved, the wind resistance during pesticide application operations of the sprayer is reduced, the quality of pesticide application operations of the sprayer in main-stem type high-density orchards is improved, and at the same time, the manufacturing cost is reduced and the energy consumption is reduced; by adopting an electromagnetic clutch pulley, the axial flow fan and the medicine pump are controlled to work and stop simultaneously, realizing one-key control of air-assisted spraying, simplifying the structure, and saving space.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A double-wing type lightweight and efficient air-blast orchard sprayer, characterized in that: the orchard sprayer is composed of a traveling system, a spraying system, a control system and an energy supply system. Among them, the traveling system adopts a three-wheel rear-wheel drive structure, which is composed of a steering handlebar 1, a frame 3, a traveling transmission module 5, a rear axle assembly 7, rear wheels 10 and a seat 12. The traveling transmission module 5 includes a first belt 5-1, a universal joint input shaft 5-2, a pedestal bearing 5-3, a pedestal bearing 5-4, an output sprocket 5-5, a gearbox 5-6, an input sprocket 5-7, a gearbox input pulley 5-8, a chain 5-9, an input universal joint 5-10, a universal drive shaft 5-11 and an output universal joint 5-12; the spraying system is composed of a medicine pump 6, a double-wing axial flow spraying device 8, a spraying transmission module 9 and a medicine tank 11; the control system mainly includes an intermediate relay control module 13; the energy supply system includes a diesel engine 2, a battery pack 4, an electronic regulator 14, an excitation generator 15, a generator input pulley 16 and a power generation drive belt 17; the traveling system, the spraying system, the control system and the energy supply system work together to realize the functions of the sprayer traveling and air-blast spraying.

[0007] Further, the double-wing axial flow spraying device 8 includes a double-wing air guide plate 8-1, a front air guide plate 8-2, a rear air guide plate 8-3, an axial flow fan 8-4, an air guide bottom plate 8-5, a fan support 8-6, a nozzle 8-7, a high-pressure pipe 8-8, a diversion platform 8-9 and a nozzle fixing stud 8-10. The axis of the axial flow fan 8-4 is 615 mm away from the bottom of the air guide bottom plate 8-5, and the total height of the front air guide plate 8-2 and the rear air guide plate 8-3 is 1786 mm.

[0008] Further, the spray drive module 9 includes a diesel engine pulley 9-1, a second belt 9-2, a medicine pump input pulley 9-3, a third belt 9-4, an electromagnetic clutch drive device 9-5, a pedestal bearing three 9-6, a spray drive shaft 9-7, a pedestal bearing four 9-8, a spray drive intermediate pulley 9-9, a fourth belt 9-10, and a fan input pulley 9-11; the electromagnetic clutch drive device 9-5 includes a suction cup 9-5-1, an electromagnetic clutch input pulley 9-5-2, a coil 9-5-3, an oil guard 9-5-4, a spring piece 9-5-5, a bearing group 9-5-6, an electromagnetic clutch output pulley 9-5-7, a screw 9-5-8, a gland 9-5-9, a first flat key 9-5-10, and a second flat key 9-5-11.

[0009] Further, the shape of the double-wing air deflector 8-1 is V-shaped, and the included angle is 120°.

[0019] An embodiment of the present invention discloses a double-wing type lightweight and efficient air-assisted orchard sprayer. The overall structure is as Figure 1 shown, and it is composed of a traveling system, a spraying system, a control system, and an energy supply system. Among them, the traveling system is composed of a steering handlebar (1), a frame (3), a traveling transmission module (5), a rear axle assembly (7), rear wheels (10), and a seat (12), which can realize the traveling function of the machine. The steering handlebar (1) is welded to the front side of the frame (3), the rear axle assembly (7) is fixed to the lower side of the rear part of the frame (3) by bolts, two rear wheels (10) are installed on both sides of the rear axle assembly (7) by bolts, and the seat (12) is welded to the upper side of the frame (10). The steering handlebar (1) is provided with an ignition switch knob for the diesel engine (2) and a spray control button for controlling the working state of the intermediate relay in the intermediate relay control module (13); the spraying system is composed of a medicine pump (6), a double-wing axial flow spraying device (8), a spraying transmission module (9), and a medicine box (11). The medicine pump (6) pressurizes and transports the pesticides in the medicine box (11) to the double-wing axial flow spraying device (8), and its power is input by the spraying transmission module (9), which can realize the air-assisted spraying function of the machine; the control system mainly includes an intermediate relay control module (13), and the working state of the intermediate relay is controlled by the spray control button, which can control the start and stop of the air-assisted spraying; the energy supply system is composed of a diesel engine (2), a battery pack (4), an electronic regulator (14), an excitation generator (15), a generator input pulley (16), and a power generation drive belt (17). The diesel engine (2) is the total power source of the sprayer, and drives the generator input pulley (16) through the power generation drive belt (17), so that the excitation generator (15) charges the battery pack (4), thereby supplying power to the control system. The electronic regulator (14) stabilizes the charging voltage of the battery pack (4) to protect the battery pack (4); the traveling system, the spraying system, the control system, and the energy supply system work together to achieve efficient spraying operations in the orchard.

[0020] The structure of the traveling transmission module (5) is as Figure 2As shown in the figure, it includes belt 1 (5-1), cardan input shaft (5-2), pedestal bearing 1 (5-3), pedestal bearing 2 (5-4), output sprocket (5-5), gearbox (5-6), input sprocket (5-7), gearbox input pulley (5-8), chain (5-9), input universal joint (5-10), universal drive shaft (5-11) and output universal joint (5-12). Belt 1 (5-1) is sleeved on the diesel engine pulley (9-1) and the gearbox input pulley (5-8) to transmit the output power of the diesel engine (2) to the gearbox (5-6). By adjusting the matching control lever of the gearbox (5-6), the rotation speed of the input sprocket (5-7) can be changed, and then the rotation speed of the output sprocket (5-5) can be changed through the chain (5-9); the cardan input shaft (5-2) rotates coaxially and synchronously with the output sprocket (5-5), and the power is transmitted to the rear axle assembly (7) through the universal drive device composed of the input universal joint (5-10), universal drive shaft (5-11) and output universal joint (5-12), and then the rear wheels are driven to rotate at different speeds to realize the driving and speed change of the sprayer.

[0021] The structure of the double-wing axial flow spray device (8) is as Figure 3 shown, including double-wing air guide plate (8-1), front air guide plate (8-2), rear air guide plate (8-3), axial flow fan (8-4), air guide bottom plate (8-5), fan support (8-6), nozzle (8-7), high-pressure pipe (8-8), diversion platform (8-9) and nozzle fixing stud (8-10). When the axial flow fan (8-4) works, a negative pressure is formed inside relative to the outside, and the external air flow is directionally transported to the space surrounded by the double-wing air guide plate (8-1), front air guide plate (8-2), rear air guide plate (8-3), air guide bottom plate (8-5) and diversion platform (8-9). The diversion platform (8-9) is welded to the rear air guide plate (8-3), and its side guides the air flow to output laterally; the axis of the axial flow fan (8-4) is 615 mm away from the bottom of the air guide bottom plate (8-5), and the total height of the front air guide plate (8-2) and the rear air guide plate (8-3) is 1786 mm. By adopting reasonable height dimensions of the axial flow fan, front air guide plate and rear air guide plate, the lateral output air flow speed at the top of the air outlet of the double-wing axial flow spray device can be increased; the shape of the double-wing air guide plate (8-1) is V-shaped, and the included angle is 120°. Therefore, when the internal air flow at the top of the spray device contacts the double-wing air guide plate, the air flow is guided to both sides, which can increase the lateral output air flow speed at the top; when the sprayer travels in the orchard, the contact area between the forward air flow and the double-wing axial flow spray device is reduced, and the wind resistance is reduced, which can reduce the energy consumption.

[0022] The structure of the spray drive module (9) is as Figure 4As shown in the figure, it includes a diesel engine pulley (9-1), a second belt (9-2), a medicine pump input pulley (9-3), a third belt (9-4), an electromagnetic clutch transmission device (9-5), a pedestal bearing three (9-6), a spray transmission shaft (9-7), a pedestal bearing four (9-8), a spray transmission intermediate pulley (9-9), a fourth belt (9-10) and a fan input pulley (9-11). The diesel engine pulley (9-1) transmits the output power to the power input end of the electromagnetic clutch transmission device (9-5) through the second belt (9-2). The power output end of the electromagnetic clutch transmission device (9-5) rotates the medicine pump input pulley (9-3) through the third belt (9-4) to drive the medicine pump (6) to work. At the same time, the power output end of the electromagnetic clutch transmission device (9-5) drives the spray transmission intermediate pulley (9-9) through the spray transmission shaft (9-7), and then rotates the fan input pulley (9-11) through the fourth belt (9-10) to drive the axial flow fan (8-4) to work. Therefore, only by controlling the power transmission between the power input end and the power output end of the electromagnetic clutch transmission device (9-5), the medicine pump (6) and the axial flow fan (8-4) can be controlled to work at one time. The advantage of this design is that it simplifies the structure of the spray transmission module and is convenient for maintenance, and the axial flow fan and the medicine pump can be started and stopped simultaneously.

[0023] The structure of the electromagnetic clutch transmission device (9-5) is as Figure 5As shown in the figure, it includes a suction cup (9-5-1), an electromagnetic clutch input pulley (9-5-2), a coil (9-5-3), an oil guard cover (9-5-4), a shrapnel (9-5-5), a bearing set (9-5-6), an electromagnetic clutch output pulley (9-5-7), a screw (9-5-8), a gland (9-5-9), a flat key one (9-5-10) and a flat key two (9-5-11). The electromagnetic clutch input pulley (9-5-2) is the power input end of the electromagnetic clutch transmission device (9-5), and a coil (9-5-3) is embedded on its right side; the spray drive shaft (9-7), the suction cup (9-5-1) and the electromagnetic clutch output pulley (9-5-7) constitute the power output end of the electromagnetic clutch transmission device (9-5), wherein the suction cup (9-5-1) is arranged on the left side of the electromagnetic clutch input pulley (9-5-2) with a certain distance, and the spray drive shaft (9-7) is synchronously rotated with it through the flat key two (9-5-11), and the electromagnetic clutch output pulley (9-5-7) is synchronously rotated with the spray drive shaft (9-7) through the flat key one (9-5-10); therefore, when the coil (9-5-3) is energized, if the electromagnetic clutch input pulley (9-5-2) is in a rotating state, the suction cup (9-5-1) contacts and rotates with the electromagnetic clutch input pulley (9-5-2) under the action of electromagnetic force, so as to drive the spray drive shaft (9-7) and the electromagnetic clutch output pulley (9-5-7) to rotate respectively, and the power is transmitted to the power output end of the electromagnetic clutch transmission device (9-5); when the coil (9-5-3) is de-energized, due to the elasticity of the shrapnel (9-5-5), the suction cup (9-5-1) is separated from the electromagnetic clutch input pulley (9-5-2), and the suction cup (9-5-1) stops rotating. Such a design only needs to control the energization state of the coil (9-5-3) to control the transmission from the power input end to the power output end of the electromagnetic clutch transmission device (9-5), which is easy to control, saves space and has a rapid response.

[0024] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
