Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, specifically to a ride-on electric drive pesticide spraying machine. Background Technology

[0002] A pesticide sprayer is an agricultural, horticultural, and forestry equipment used for applying pesticides to plants. Its core function is to atomize or evenly spray pesticides, foliar fertilizers, growth regulators, and other agents onto the surface of crops and seedlings as needed, thereby achieving pest and disease control, weed removal, and crop growth regulation. It is widely used in field planting, orchard management, vegetable greenhouses, forestry seedling cultivation, and urban greening.

[0003] Existing sprayers use a manual hydraulic drive system, which is prone to oil leakage after long-term use or component wear. Leaking hydraulic oil can not only seep into the soil, damaging soil aggregate structure and reducing soil fertility, but may also adhere to the surface of crop leaves, forming an oil film that hinders photosynthesis and respiration, causing a double negative impact on land ecology and crop growth. At the same time, the slow extension and retraction speed of the sprayer's arm significantly prolongs the operation time and reduces the overall spraying efficiency. Furthermore, when the sprayer passes through low-lying soil surfaces, the change in the nozzle's ground clearance causes uneven spraying. When encountering obstacles such as trees or walls, the arm span is several times the width of the vehicle, and misjudgment by the driver can lead to collisions with the spray boom arm, seriously affecting the normal use and service life of the sprayer.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-8 As shown, in one embodiment, a ride-on electric sprayer includes: a vehicle chassis 1 to ensure the safety of operators working in the field (such as on bumpy roads or in scenarios with a risk of rollover), and a high-strength anti-rollover frame 11 is fixedly installed on the top of the vehicle chassis 1.

[0021] The vehicle chassis 1 has a steering front axle assembly 2 and a drive rear axle assembly 3 installed at the bottom, which are used for steering adjustment and power output of the spraying equipment, respectively; correspondingly, the vehicle chassis 1 has an electronically controlled drive assembly 4 installed inside to control the operation of the equipment, and a medicine tank conveying assembly 5 for conveying medicine is installed on the top of the vehicle chassis 1.

[0022] For example, the steering front axle assembly 2 includes a steering axle assembly 21, which consists of two parallel steering crossbars and front wheel mounting seats at the ends. A steering cylinder 22 is provided between the steering axle assemblies 21. The piston rod end of the steering cylinder 22 is rotatably connected to one end of the steering connecting rod 24 through a straight rod end spherical bearing 23. This spherical bearing 23 design can eliminate radial deviation during the steering process and ensure smooth power transmission. The other end of the steering connecting rod 24 is rotatably connected to the steering crossbar of the steering axle assembly 21 through a rod end spherical joint 25. The spherical joint 25 has multi-directional rotational freedom and can adapt to the angle changes of each component when the front wheels are steering, avoiding mechanical jamming.

[0023] It should be explained in detail that an angle position sensor (not shown in the figure as prior art) is provided on the side where the steering cylinder 22 is connected to the steering axle assembly 21. By collecting the extension and retraction length of the piston rod of the steering cylinder 22 in real time, it is converted into the actual rotation angle of the steering axle assembly 21, and the data is fed back to the electronic control system to form a closed-loop control, thereby realizing precise control of the front wheel steering and ensuring that the equipment will not deviate when traveling along the preset route.

[0024] Furthermore, the drive rear axle assembly 3 includes a drive axle assembly 31, which includes two symmetrical drive half-shafts and rear wheel mounting seats at the ends. A three-phase asynchronous drive motor 32 is arranged between the drive axle assemblies 31. The output shaft of the motor is rotatably connected to the input end of the drive axle assembly 31 through a coupling. The three-phase asynchronous motor has the characteristics of stable speed and large torque. It can automatically adjust the output power according to the operation requirements, so that the drive unit composed of the two rear wheels, the drive motor and the differential can maintain a stable driving speed under different road conditions.

[0025] For example, the electronically controlled drive assembly 4 includes an electronic control box 41, which can send control signals to various components of the equipment according to a preset program or external instructions. Internally, it is equipped with a wireless transceiver module and a positioning module. The wireless transceiver module can achieve real-time data interaction with clients such as mobile phones and tablets, while the GPS positioning module can accurately obtain the equipment's location information and generate the optimal spraying route by combining it with the client's path planning function. It also supports a remote unmanned driving mode, allowing operators to complete large-area pesticide application without on-site supervision. Correspondingly, a driver 42 is installed on the top of the electronic control box 41. The driver 42 is electrically connected to the three-phase asynchronous drive motor 32, steering cylinder 22, and other actuators, responsible for converting the control signals of the electronic control box 41 into power signals. A battery pack 43 is installed on one side of the electronic control box 41, connected to all electrical components such as the electronic control box 41, driver 42, and motor via wires, providing continuous and stable power support for the equipment. The battery pack 43 has fast charging and overload protection functions to meet the needs of long-term operation.

[0026] Understandably, by using the electronically controlled drive assembly 4 to drive the steering front axle assembly 2, the drive rear axle assembly 3, and the spraying swing arm assembly 7, the hydraulic drive mode is eliminated, thus fundamentally eliminating the possibility of hydraulic oil leakage. This avoids problems such as reduced fertility due to oil seepage into the soil, pollution of crop roots, and oil film adhering to leaves affecting photosynthesis. At the same time, it reduces the maintenance cost and mechanical failure risk of the hydraulic system. The linear power output by the steering electric cylinder 22, combined with the real-time feedback from the angle position sensor, enables the drive wheels to rotate strictly according to the angle preset by the electronic control system. Even in complex road conditions, it can ensure the accuracy of the driving trajectory and avoid missed spraying or repeated spraying due to steering deviation.

[0027] For example, the medicine tank delivery assembly 5 includes a spray tank 51, and a medicine tank cover 52 is installed on the top of the spray tank 51. The edge of the medicine tank cover 52 is provided with a rubber sealing ring to prevent the medicine from spilling during operation. Furthermore, multiple sets of water outlet and return connectors 53 are evenly distributed on the top of the medicine tank cover 52. The water outlet and return connectors 53 adopt a quick-connect design to facilitate quick connection of the medicine delivery pipeline, while realizing the circulation delivery and pressure regulation of the medicine.

[0028] Please continue reading. Figures 1-8 In this embodiment, a manned driving component 6 is installed at the front of the medicine tank delivery assembly 5 to provide a comfortable driving and operating space for the operator; a spraying swing arm assembly 7 is installed at the rear of the medicine tank delivery assembly 5 to achieve large-area application of medicine; and an integrated valve assembly 8 is provided on one side of the medicine tank delivery assembly 5 to regulate the flow and pressure of the medicine.

[0029] Furthermore, the human-machine driving component 6 includes a riding seat 61, which is filled with high-elasticity sponge and covered with waterproof and wear-resistant fabric to alleviate operator fatigue during long-term operation. A steering mechanism 62 and a display 63 are located in front of the riding seat 61. The steering mechanism 62 is electronically assisted; the operator can send steering commands to the electronic control system by turning the steering mechanism 62, achieving precise steering in conjunction with the angle and position sensors. The display 63 can display key parameters such as the equipment's speed, remaining battery power, remaining pesticide, and spray flow rate in real time, and also supports modification of operating parameters via the screen. In addition, an electric accelerator pedal 64 is located at the bottom of the riding seat 61, connected to the electronic control system via a pressure sensor. The force applied by the operator to the electric accelerator pedal 64 is converted into a motor speed adjustment signal, achieving linear control of the equipment's speed, making operation convenient and responsive.

[0030] For example, the spraying arm assembly 7 includes a middle spraying mechanism 71 and a swing arm spraying mechanism 72. In order to achieve flexible rotation and buffering of the swing arm spraying mechanism 72, the two sides of the middle spraying mechanism 71 are respectively rotatably connected to the swing arm spraying mechanism 72 through a cam elastic mechanism 73. The cam elastic mechanism 73 can transmit the spraying pipeline and provide buffering protection when encountering obstacles to avoid mechanical damage. For example, the mid-range spraying mechanism 71 includes a spray pipe base 711, and a set of perforated stainless steel spray nozzle bars 722 are detachably installed inside the spray pipe base 711; the swing arm spraying mechanism 72 includes a spray bar turret 721, and another set of perforated stainless steel spray nozzle bars 722 are also detachably installed inside the spray bar turret 721. Stainless steel has the advantages of being resistant to pesticide corrosion and having high strength, and the detachable design facilitates later cleaning, maintenance or replacement. Specifically, each spray bar has multiple sets of multi-head nozzles 723 with anti-drip function detachably installed in the middle, which can convert the agent into fine droplets, improve the agent adhesion rate, and at the same time the anti-drip function can avoid local pesticide damage caused by the nozzle dripping when the operation is stopped; and the end of the spray bar is equipped with an adapter 724 for connecting to the spray box 51 through the pipeline to form a complete agent delivery channel. Furthermore, the cam elastic mechanism 73 includes a limiting shaft 731, with a support swing seat 732 and a support base 733 installed on both sides of the end of the limiting shaft 731. A cylindrical helical compression spring 735 is symmetrically mounted on the limiting shaft 731 through a limiting ring 734. The spring has a high elastic coefficient and can generate compression deformation when the swing arm spraying mechanism 72 is subjected to external force impact, thereby absorbing impact energy and achieving buffer protection. It should be noted that the outer side of the support base 733 is detachably connected to the cam seat 736 by bolts; the side of the cam seat 736 is detachably connected to the side of the nozzle base 711 by bolts, ensuring a stable connection between the middle spraying mechanism 71 and the cam elastic mechanism 73.

[0031] Correspondingly, electric push rods 74 are symmetrically installed on nozzle base 711, and a retracting frame 75 is installed between the electric push rods 74; a swing arm support seat 76 is installed in the middle of the retracting frame 75, and a swing arm limit seat 77 is installed on the top of the retracting frame 75, which is used to retract the nozzle turret 721.

[0032] It should be noted in detail that an ultrasonic sensor (not shown in the figure as prior art) is installed at the end of the spray boom turret 721. The sensor's detection direction is perpendicular to the ground and horizontal, and it can scan the environmental road conditions around the spray boom turret 721 in real time: in the vertical direction, it can detect the undulations of the road surface and identify low-lying areas; in the horizontal direction, it can identify obstacles such as soil, gravel, and weeds in front, and feed the detection data back to the electronic control system in real time; the electronic control system automatically determines whether the swing arm height needs to be adjusted based on the sensor data, providing data support for obstacle avoidance actions; Understandably, when the spraying arm assembly 7 passes through a low-lying road surface or encounters an obstacle, the ultrasonic sensor detects a decrease in ground height and sends a control signal to control the electric push rod 74 to extend appropriately, driving the spray boom turret 721 to make fine adjustments in height, ensuring that the multi-head nozzle 723 on the spray boom turret 721 maintains a constant distance from the ground surface, and avoiding collisions that could damage the arm.

[0033] Understandably, when obstacles such as clods of earth are detected ahead, the cylindrical spiral compression spring 735 in the cam elastic mechanism 73 will deform according to the collision force, further buffering the impact. After the equipment passes the obstacle, the electric push rod 74 and the compression spring 735 will automatically reset, bringing the spray boom turret 721 back to its original working position. Therefore, it can solve the problem of easy collision damage caused by rigid connection of traditional swing arms, extend the service life of the spraying components, and ensure the continuity of the spraying process.

[0034] It should be noted in detail that the integrated valve assembly 8 includes a control valve assembly 81, which includes a main control valve, a proportional control valve, a filter, a flow meter, and an electrically controlled valve (not shown in the figure as prior art). The main control valve is responsible for controlling the overall switch of pesticide delivery. The proportional control valve can precisely adjust the pesticide flow rate according to crop needs. The filter can filter impurities in the pesticide to prevent clogging of the nozzle. The flow meter monitors the pesticide delivery in real time and feeds back to the electrical control system. The electrically controlled valve is remotely controlled by electrical control signals. The inlet of the control valve assembly 81 is connected to the outlet and return water connectors 53 of the spray box 51 through an outlet adapter. The outlet is connected to the adapter 724 of the spray bar through a high-pressure hose, forming a complete pesticide delivery control path. For easy installation and maintenance, the control valve assembly 81 is detachably mounted on the mounting bracket 82 by bolts. The mounting bracket 82 is fixed to the rear of the vehicle chassis 1 by welding or bolts, and its position is convenient for operators to inspect and adjust daily.

[0035] Understandably, the integrated valve assembly 8 on top of the spraying arm assembly 7 works in concert with the wireless transceiver module and GPS positioning module of the electrical control box 41 for coordinated control. In unmanned driving mode, after the GPS positioning module determines the location of the equipment, the electrical control system automatically plans the spraying area according to the preset spraying route. The wireless transceiver module receives the application parameter instructions from the client and transmits them to the control valve assembly 81. The proportional control valve in the control valve assembly 81 works with the flow meter to precisely control the amount of pesticide output from each set of nozzles, avoiding repeated spraying (such as automatically reducing the flow of the inner nozzles at turns) or missed spraying due to changes in driving speed or route deviation. At the same time, the electrical control system can record the spraying area and the amount of pesticide applied in real time and feed it back to the client through the wireless module, which is convenient for operators to perform subsequent statistics and analysis, and realize intelligent and precise pesticide application management.

[0036] Furthermore, a diaphragm pump 9 is installed on one side of the spraying tank 51. This diaphragm pump 9 uses the latest corrosion-resistant materials such as polytetrafluoroethylene diaphragm. Compared with traditional metal pump bodies, its resistance to pesticide corrosion is greatly improved. It can effectively resist the erosion of the pump body by acidic and alkaline agents, and significantly extend the service life of the pump body. At the same time, the pressure stability of the diaphragm pump 9 is stronger, which can provide continuous and uniform pressure for pesticide delivery and ensure consistent atomization effect of the nozzle. On the other side of the spraying tank 51, a retractor 10 is installed on the vehicle chassis 1 for retracting the high-pressure water hose. After the operation is completed, the retractor 10 can be started to automatically retract the water hose, preventing the water hose from falling into the field and causing damage or affecting the operation of the equipment.

[0037] Working principle: The electrical control box 41 plans the spraying route through the GPS positioning module, and combined with the wireless transceiver module, realizes remote unmanned driving or receives operation commands from the human-machine driving component 6. This causes the drive motor 32 of the rear axle component 3 to drive the rear wheels, while controlling the steering cylinder 22 of the steering front axle component 2 in conjunction with the angle and position sensor to complete the precise steering by wire control, completely removing the hydraulic drive to avoid oil contamination. The pesticide stored in the spray tank 51 is pressurized by the diaphragm pump 9, and the flow rate is regulated and impurities are filtered by the integrated valve group before being transported to the spraying pen through pipelines. The middle section of the arm assembly 7 and the spray nozzle bar 722 of the swing arm are ultimately atomized and sprayed by the multi-head nozzle 723 with anti-drip function; while the ultrasonic sensor at the end of the spray boom turret 721 detects changes in road conditions in real time, thereby driving the electric push rod 74 to adjust the height of the spray swing arm in real time; in conjunction with the cylindrical helical compression spring 735 of the cam elastic mechanism 73 to buffer and avoid obstacles, it automatically resets after passing through, and at the same time the control valve group 82 combines the positioning data to accurately control the amount of spraying, avoiding repeated spraying or missed spraying, and finally completing the efficient, environmentally friendly and precise field spraying operation.
