Description
Technical Field
[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a dual-wing type lightweight, simplified, and efficient wind-driven orchard sprayer. Background Technology
[0002] Orchard pesticide application can reduce most fruit losses and plays an important role in improving fruit yield and quality. Airflow-assisted spraying technology is a highly efficient spraying technique that has been widely used in orchard pesticide application to improve the quality of pesticide spraying operations. Summary of the Invention
[0004] Currently, the new type of high-density orchard with a central trunk is being widely promoted and planted, utilizing the apical dominance of fruit trees to increase yield and improve quality. The characteristics of this type of orchard are narrow canopies and tall trees. However, traditional wind-driven orchard sprayers have many problems. For example, some sprayers reduce the windward area by lowering the height of the spraying device, thereby reducing the machine's wind resistance. However, this results in low wind speeds in areas above 5 meters, making the spraying effect on the top of the fruit trees poor. The spraying drive device has a complex structure. Some wind-driven sprayers use a tension wheel to control the operation of the pesticide pump, which leads to low machine transmission efficiency, increased energy consumption, and a complex cable-stayed device, which increases the difficulty of processing.
[0005] To improve the spraying effect of wind-assisted sprayers on the tops of fruit trees in densely planted orchards with a trunk-type structure, and to save costs, reduce energy consumption, and simplify the structure, it is necessary to design an orchard wind-assisted sprayer that can provide high-speed airflow and efficiently control spraying in areas above 5 meters. Utility Model Content
[0006] In view of this, the present invention provides a simplified and efficient double-wing type air-assisted orchard sprayer. By adopting double-wing guide vanes and supplementing them with a reasonable axial flow fan, front guide vane and rear guide vane height dimensions, the top lateral output wind speed is increased, while saving materials and reducing the wind resistance of the sprayer during spraying operations. This improves the spraying quality of the sprayer in densely planted orchards with a main trunk, while reducing manufacturing costs and energy consumption. By using an electromagnetic clutch pulley to control the axial flow fan and the pesticide pump to work and stop simultaneously, one-button control of the air-assisted spraying is achieved, simplifying the structure and saving space.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a lightweight, simplified, and efficient wind-driven orchard sprayer with a double-wing design, characterized in that: the orchard sprayer consists of a walking system, a spraying system, a control system, and a power supply system, wherein the walking system adopts a three-wheeled rear-drive structure, consisting of a steering handle 1, a frame 3, a walking transmission module 5, a rear axle assembly 7, a rear wheel 10, and a seat 12.

[0008] Furthermore, the dual-wing axial flow spray device 8 includes a dual-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 base plate 8-5, a fan support 8-6, a nozzle 8-7, a high-pressure pipe 8-8, a flow guide 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 base 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.
[0009] Furthermore, the spray transmission 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 transmission device 9-5, a third bearing 9-6, a spray transmission shaft 9-7, a fourth bearing 9-8, an intermediate spray transmission pulley 9-9, a fourth belt 9-10, and a blower input pulley 9-11; the electromagnetic clutch transmission 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 cover 9-5-4, a spring 9-5-5, and a bearing assembly 9-5-1. -5-6, electromagnetic clutch output pulley 9-5-7, screw 9-5-8, pressure cap 9-5-9, flat key one 9-5-10, and flat key two 9-5-11. The coil 9-5-3 is embedded on the right side of the electromagnetic clutch input pulley 9-5-2. The spray drive shaft 9-7 rotates synchronously with the electromagnetic clutch output pulley 9-5-7 via flat key one 9-5-10, and synchronously with the suction cup 9-5-1 via flat key two 9-5-11. The spring piece 9-5-5 is located between the electromagnetic clutch input pulley 9-5-2 and the oil cover 9-5-4.

[0010] Furthermore, the double-wing air guide plate 8-1 is V-shaped with an included angle of 120°. Therefore, when the airflow inside the top of the spray device comes into contact with the double-wing air guide plate, the airflow is guided to both sides, which can increase the speed of the lateral output airflow at the top. When the sprayer is running, the contact area between the airflow in front and the double-wing axial flow spray device is reduced, and the wind resistance is reduced, which can reduce energy consumption.

At the same time, the device is smaller in size, saving materials. Moreover, when the sprayer is running, the contact area between the forward airflow and the front air guide plate 8-2 and the rear air guide plate 8-3 is reduced, and the wind resistance is reduced, which can reduce energy consumption. The electromagnetic clutch transmission device 9-5 can control the rotation and stop of the spraying drive shaft 9-7 by using the attraction and disengagement states of the suction cup 9-5-1 and the coil 9-5-3, and at the same time control the operation and stop of the axial flow fan 8-4 and the pesticide pump 6, which can realize one-button control of wind-driven spraying. This utility model can effectively solve the problems of insufficient wind speed at the top of the trunk-type densely planted orchards and complex structure and high energy consumption. It has a simple structure and is easy to control. Attached Figure Description

Detailed Implementation
[0019] 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.
[0020] This utility model discloses a lightweight, simplified, and efficient air-assisted orchard sprayer with a dual-wing design. The overall structure is as follows: Figure 1 As shown, the system consists of a walking system, a spraying system, a control system, and a power supply system. The walking system consists of a steering handle (1), a frame (3), a walking transmission module (5), a rear axle assembly (7), rear wheels (10), and a seat (12), which enables the machine to walk. The steering handle (1) is welded to the front of the frame (3), the rear axle assembly (7) is fixed to the lower rear of the frame (3) with bolts, the two rear wheels (10) are bolted to both sides of the rear axle assembly (7), and the seat (12) is welded to the upper side of the frame (10). The steering handle (1) is equipped with an ignition switch knob for the diesel engine (2) and a spray control button in the intermediate relay control module (13) for controlling the working state of the intermediate relay. The spraying system consists of a pesticide pump (6), a double-wing axial flow spray device (8), a spray transmission module (9), and a pesticide tank (11). The pesticide pump (6) pressurizes and delivers the pesticide in the pesticide tank (11) to the double-wing axial flow spray device (8). Its power is input from the spray transmission module (9), which can realize the machine's wind-driven spraying function; the control system mainly includes the intermediate relay control module (13), which controls the working state of the intermediate relay through the spray control button, and can control the start and stop of the wind-driven spraying; the power supply system consists of a diesel engine (2), a battery pack (4), an electronic regulator (14), an excitation generator (15), a generator input pulley (16), and a generator transmission belt (17). The diesel engine (2) is the total power source of the sprayer. The generator input pulley (16) is driven by the generator transmission 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 walking system, spraying system, control system, and power supply system work together to realize efficient spraying operations in the orchard.
[0021] The structure of the walking transmission module (5) is as follows: Figure 2As shown, it includes belt one (5-1), universal joint input shaft (5-2), bearing one (5-3), bearing two (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 fitted onto the diesel engine pulley (9-1) and the gearbox input pulley (5-8), transmitting the power output from the diesel engine (2) to the gearbox (5-6). By adjusting the control lever of the gearbox (5-6), the speed of the input sprocket (5-7) can be changed, and then the speed of the output sprocket (5-5) can be changed through the chain (5-9). The universal joint input shaft (5-2) rotates synchronously with the output sprocket (5-5) on the same axis. Through the universal joint (5-10), universal drive shaft (5-11), and output universal joint (5-12), the power is transmitted to the rear axle assembly (7), thereby driving the rear wheels to rotate at different speeds, thus realizing the driving of the sprayer to travel and change speed.
[0022] The structure of the double-wing axial flow spray device (8) is as follows: Figure 3 As shown, the system includes a double-winged 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 base plate (8-5), a fan support (8-6), a nozzle (8-7), a high-pressure pipe (8-8), a flow guide platform (8-9), and a nozzle fixing stud (8-10). When the axial flow fan (8-4) is working, it creates a negative pressure inside relative to the outside, directing the external airflow to the space enclosed by the double-winged air guide plate (8-1), the front air guide plate (8-2), the rear air guide plate (8-3), the air guide base plate (8-5), and the flow guide platform (8-9). The flow guide platform (8-9) is welded to the rear air guide plate (8-3), and its side guides the airflow for lateral output. The axis of the axial flow fan (8-4) is 615 mm from the bottom of the air guide base plate (8-5). The total height of the front guide vane (8-2) and the rear guide vane (8-3) is 1786 mm. By adopting reasonable axial flow fan, front guide vane and rear guide vane height dimensions, the lateral output airflow velocity at the top of the air outlet of the double-wing axial flow spray device can be increased. The double-wing guide vane (8-1) is V-shaped with an included angle of 120°. Therefore, when the airflow inside the top of the spray device comes into contact with the double-wing guide vane, the airflow is guided to both sides, which can increase the lateral output airflow velocity at the top. When the sprayer travels in the orchard, the contact area between the forward airflow and the double-wing axial flow spray device is reduced, the wind resistance is reduced and energy consumption can be reduced.
[0023] The structure of the spray transmission module (9) is as follows: Figure 4As shown, it includes a diesel engine pulley (9-1), belt two (9-2), a medicine pump input pulley (9-3), belt three (9-4), an electromagnetic clutch transmission device (9-5), a seated bearing three (9-6), a spray drive shaft (9-7), a seated bearing four (9-8), a spray drive intermediate pulley (9-9), belt four (9-10), and a blower 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 belt two (9-2). The power output end of the electromagnetic clutch transmission device (9-5) drives the input pulley (9-3) of the medicine pump to rotate through belt three (9-4), thereby driving the medicine pump (6) to work. At the same time, the power output end of the electromagnetic clutch transmission device (9-5) drives the intermediate pulley (9-9) of the spray transmission through the spray transmission shaft (9-7), and then drives the input pulley (9-11) of the fan to rotate through belt four (9-10), thereby driving the axial flow fan (8-4) to work. Therefore, it is only necessary to control the power transmission between the power input end and the power output end of the electromagnetic clutch transmission device (9-5) to control the operation of the medicine pump (6) and the axial flow fan (8-4) at one time. The advantage of this design is that it simplifies the structure of the spray transmission module, is easy to maintain, and can realize the simultaneous start and stop of the axial flow fan and the medicine pump.
[0024] The structure of the electromagnetic clutch transmission device (9-5) is as follows: Figure 5As shown, it includes a suction cup (9-5-1), an electromagnetic clutch input pulley (9-5-2), a coil (9-5-3), an oil cover (9-5-4), a spring (9-5-5), a bearing assembly (9-5-6), an electromagnetic clutch output pulley (9-5-7), a screw (9-5-8), a pressure cap (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), suction cup (9-5-1), and electromagnetic clutch output pulley (9-5-7) constitute the power output end of the electromagnetic clutch transmission device (9-5). The suction cup (9-5-1) is located to the left of the electromagnetic clutch input pulley (9-5-2) with a certain distance. The spray drive shaft (9-7) rotates synchronously with it through the second flat key (9-5-11). The spray drive shaft (9-7) rotates synchronously with the electromagnetic clutch output pulley (9-5-2) through the first flat key (9-5-10). 7) It rotates synchronously with it; therefore, when the coil (9-5-3) is energized, if the electromagnetic clutch input pulley (9-5-2) is rotating, the suction cup (9-5-1) will rotate due to friction caused by contact with the electromagnetic clutch input pulley (9-5-2) under the action of electromagnetic force, thereby driving 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 spring (9-5-5), the suction cup (9-5-1) separates from the electromagnetic clutch input pulley (9-5-2), and the suction cup (9-5-1) stops rotating. This design only requires controlling 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 fast response.
[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
