Description

Technical Field

[0001] This invention relates to the field of orchard weeding robot technology, and more particularly to an automatically adjustable orchard weeding robot. Background Technology

[0002] Orchard weeding robots are a powerful assistant in orchard management. The robots are flexible and can move freely in various terrains of the orchard. They use environmentally friendly weeding methods, such as physical weeding, which will not cause chemical pollution to the soil and environment. Orchard weeding robots also have high work efficiency and can complete large-area weeding tasks in a short time, greatly reducing the labor intensity of fruit farmers.

[0003] However, traditional lawnmowers use a passenger-operated design and are fuel-powered to drive the blades. During operation, passengers are easily injured by tree branches or other obstacles, or their safety is compromised on steep slopes. Fuel-powered machines consume a lot of energy and have no adjustable blade speed, resulting in the same speed and fuel consumption regardless of whether the grass is very tender or very tall, leading to energy waste and environmental pollution. Additionally, the blades are easily tangled by broken grass during mowing, causing them to become knotted and increasing the equipment's failure rate. Traditional pesticide sprayers also require passengers to operate them, which can easily lead to poisoning and other driving accidents.

[0004] To address the issues of excessive power consumption and unadjustable blade speed in fuel-powered systems, which result in the same rotation speed regardless of the grass being tender or tall, leading to energy waste and environmental pollution, and the blades being prone to tangling with broken grass during mowing, increasing equipment failure rates, current technology uses fuel-powered systems. However, this results in significant power consumption and further contributes to energy waste and environmental pollution. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as excessive fuel consumption, non-adjustable cutting speed (resulting in the same rotation speed regardless of whether the grass is very tender or very tall), which leads to energy waste and environmental pollution, as well as the fact that the blades are easily entangled by broken grass during the cutting process, causing the blades to become knotted and increasing the failure rate of the equipment. Therefore, this invention proposes an automatically adjustable orchard weeding robot.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatically adjustable orchard weeding robot, comprising an unmanned vehicle, a mounting base fixedly connected to the rear of the unmanned vehicle, a connecting rod rotatably connected to the surface of the mounting base, a baffle rotatably connected to the side of the connecting rod away from the mounting base, a first motor mounted on the upper surface of the baffle, a second motor mounted on the side of the baffle closer to the first motor, a control box fixedly connected to the surface of the baffle, and a blade holder mounted on the lower surfaces of the first and second motors penetrating the baffle. A blade holder is mounted on the surface of the blade holder. The cutting tool has an auxiliary component on its lower surface, which includes a guardrail fixedly connected to the baffle. A fan blade is rotatably connected to the side of the baffle away from the guardrail, and a fan is fixedly connected to the side of the baffle near the fan blade. The drive end of the fan is fixedly connected to the fan blade. A cylinder is fixedly connected to the surface of the guardrail, and the drive end of the cylinder passes through the guardrail and is fixedly connected to a telescopic rod. A push plate is fixedly connected to the side of the telescopic rod away from the cylinder, and the push plate is L-shaped. By incorporating this invention, two high-speed motors can adjust their speed between 1000 and 3000 RPM, adapting to grasses of different hardness and height. Speed ​​adjustment saves electricity, and dual-motor operation is more energy-efficient than a single-motor operation for the same cutting width. Directly driving the cutting tool reduces energy loss during transmission, achieving high efficiency and energy saving.

[0007] Preferably, a frame is fixedly connected to the surface of the baffle, and a connecting rod is fixedly connected to one side of the frame.

[0008] Preferably, the lower surface of the connecting rod is rotatably connected to a roller, and there are two connecting rods arranged in a mirror-symmetrical manner.

[0009] Preferably, the rear of the unmanned vehicle is fixedly connected to a connecting seat, and an adjusting rod is installed on one side of the connecting seat.

[0010] Preferably, the side of the adjusting rod away from the connecting seat is rotatably connected to the frame, and the first motor and the second motor can reach 1000-3000 revolutions per minute.

[0011] Preferably, the control box consists of a battery and an optional fuel range extender, and the control box is installed above the baffle.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, two high-speed motors drive the mowing blades to cut grass. The motor speed can reach 1000-3000 RPM to handle grass of different hardness and height. Adjusting the speed saves power consumption. Two motors are more energy-efficient than one motor for the same cutting set. The two motors directly drive the blades, reducing energy consumption from belt or gear drives, resulting in high efficiency and energy saving. The bushing between the motor and the blade protects the motor shaft, increasing the blade's resilience after impact, making it more robust. The robot's power supply system consists of a battery and an optional fuel range extender. Users can choose a version with a range extender to extend the battery life. The battery is located above the center plate of the vehicle body, placing the center of gravity above the plate, which helps to compact and cut grass, improving the cutting effect. While the mowing blades are cutting grass, the fan starts, driving the blades to rotate. The rotating blades blow the cut grass towards the barrier. Simultaneously, a cylinder drives a telescopic rod to reciprocate the push plate, pushing the cut grass out of the barrier, reducing grass accumulation and preventing blade entanglement. By incorporating this invention, the two high-speed motors can reach speeds of 1000-3000 RPM. The speed can be adjusted in 3000 RPM to adapt to grasses of different hardness and height. The speed adjustment saves electricity, and the dual-motor drive is more energy-efficient than the single-motor drive for the same cutting width. Direct drive of the blades reduces energy loss in the transmission, achieving high efficiency and energy saving. At the same time, it reduces the occurrence of grass breakage and blade entanglement, reduces the equipment failure rate, facilitates maintenance, and increases the working efficiency of the equipment.

[0015] Please see Figure 1-4The present invention provides a technical solution: an automatically adjustable orchard weeding robot.

[0016] This implementation scheme includes: an unmanned vehicle 1, with a mounting base 12 fixedly connected to the rear of the unmanned vehicle 1. A connecting rod 5 is rotatably connected to the surface of the mounting base 12. A baffle 2 is rotatably connected to the side of the connecting rod 5 away from the mounting base 12. A first motor 7 is mounted on the upper surface of the baffle 2, and a second motor 8 is mounted on the side of the baffle 2 closer to the first motor 7. A control box 9 is fixedly connected to the surface of the baffle 2. A tool holder 13 is mounted through the lower surfaces of the first motor 7 and the second motor 8 on the baffle 2. A tool 14 is mounted on the surface of the tool holder 13. An auxiliary component 15 is provided on the lower surface of the baffle 2. The auxiliary component 15 includes a surrounding... The enclosure 151 is fixedly connected to the baffle 2. A fan blade 156 is rotatably connected to the side of the baffle 2 away from the enclosure 151. A fan 153 is fixedly connected to the side of the baffle 2 near the fan blade 156. The drive end of the fan 153 is fixedly connected to the fan blade 156. A cylinder 152 is fixedly connected to the surface of the enclosure 151. The drive end of the cylinder 152 passes through the enclosure 151 and is fixedly connected to a telescopic rod 155. A push plate 154 is fixedly connected to the side of the telescopic rod 155 away from the cylinder 152. The push plate 154 is arranged in an "L" shape. By setting up this invention, the two high-speed motors can adjust their speed between 1000 and 3000 revolutions, which can adapt to grasses of different hardness and height. The speed adjustment saves electricity, and the dual-motor drive is more energy-efficient than the single-motor drive for the same cutting width. Directly driving the cutter 14 reduces energy loss in the transmission and achieves high efficiency and energy saving.

[0017] Specifically, a frame 4 is fixedly connected to the surface of the baffle 2, and a connecting rod 10 is fixedly connected to one side of the frame 4.

[0018] Specifically, the lower surface of the connecting rod 10 is rotatably connected to a roller 3, and there are two connecting rods 5 arranged in a mirror-symmetrical manner.

[0019] Specifically, the rear of the unmanned vehicle 1 is fixedly connected to a connecting seat 11, and an adjusting rod 6 is installed on one side of the connecting seat 11.

[0020] Specifically, the side of the adjusting rod 6 away from the connecting seat 11 is rotatably connected to the frame 4, and the first motor 7 and the second motor 8 can reach 1000-3000 revolutions per minute.

[0021] Specifically, the control box 9 consists of a battery and an optional fuel range extender, and is installed above the baffle 2.

[0022] Working principle: Two high-speed motors drive the mowing blades 14 to cut grass. The motor speed can reach 1000-3000 rpm to handle grass of different hardness and height. Adjusting the speed saves power consumption. Two motors are more energy-efficient than one motor for the same mowing setup. The two mowing motors directly drive the blades 14, reducing energy consumption from belt or gear drives, resulting in high efficiency and energy saving. The bushings protecting the motor shaft between the motors and blades 14 increase the blades' impact resistance after collisions, making them more robust. The robot's power supply system consists of a battery and an optional fuel range extender. Users can choose to add a range extender version to extend the driving range. The battery is located above the baffle 2 in the center of the vehicle body, which places the center of gravity above the baffle 2, which helps to press and cut grass and improve the cutting effect. While the grass cutting blade 14 is cutting grass, the blower 153 is started. The blower 153 drives the fan blade 156 to rotate. As the fan blade 156 rotates, it blows the cut grass towards the enclosure 151. At the same time, the cylinder 152 drives the telescopic rod 155 to drive the push plate 154 to reciprocate and push the cut grass out of the baffle 2, reducing the possibility of grass accumulation and tangling of the blade 14. By setting up this invention, the two high-speed motors can adjust their speed between 1000-3000 rpm to adapt to grass of different hardness and height. The speed adjustment saves electricity, and the dual-motor drive is more energy-efficient than the single motor for the same cutting width. Directly driving the blade 14 reduces energy loss in the transmission, achieving high efficiency and energy saving. At the same time, it reduces the possibility of broken grass tangling the blade 14, reduces the failure rate of the equipment, facilitates maintenance, and increases the working efficiency of the equipment.
