Description

Technical Field

[0001] The present invention relates to the technical field of intelligent agricultural machinery devices, and in particular to an intelligent weeding robot operation system. Background Art

[0002] In orchard weeding operations, traditional manual weeding methods are inefficient and labor-intensive, and cannot meet the weeding needs of large orchards. With the development of social economy and the aging of the population, the cost of agricultural labor has increased rapidly, and there is even a situation where there is no labor available, which affects agricultural production. When weeding with chemical agents, chemical agents are easy to pollute the soil, and some chemical agents will be absorbed by fruit trees, affecting the quality of agricultural and sideline products. Therefore, at present, intelligent weeding robots are mostly used to replace manual weeding. When the weeding robot is in use, in order to ensure the safety of the operation, a protective shell is usually set on the outside of the cutter disc, but the setting of the protective shell is easy to cause weed debris to gather and entangle on the cutter disc shaft, which is not conducive to the use of the cutter disc, and it is difficult for personnel to remove the weeds gathered in the protective shell, which is not conducive to the use of the weeding robot.

[0003] The existing patent document CN212728067U discloses an obstacle avoidance weeding machine device, including an obstacle avoidance device and a tool transmission device; the obstacle avoidance device includes a connecting rod base, a first connecting rod, a second connecting rod, a pin shaft, a pull rod, a pull rod adjustment block, a swing arm connection block, a swing arm block, a swing hook, a tension spring, a bearing seat, a protective cover, and a hexagonal bolt. Although the obstacle avoidance weeding machine device can make the entire weeding device weed the weeds near the obstacle during the obstacle avoidance process, the weeds are easily gathered in the protective cover during the weeding process, which affects the use of the blade and is not conducive to its use.

[0004] In addition, the existing patent document CN220733557U discloses a weeder for oil-tea planting, including a weeding blade, a connecting assembly is arranged on the outer surface of the weeding blade, a protective cover is movably mounted on the outer surface of the weeding blade, a reverse threaded rod is movably mounted inside the front and rear ends of the weeding blade, and a pushing assembly is arranged on the outer surface of the protective cover. Although the weeder for oil-tea planting is provided with a connecting assembly and a pushing assembly to protect the weeding blade, it also cannot solve the problem of weeds gathering in the protective cover. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the intelligent weeding robot operating system of the example of the present invention, when the motor drives the blade to rotate through the drive shaft to weed, the exhaust fan installed on the drive shaft rotates synchronously, so that the exhaust fan draws air from the bottom, and the protective plate slides upward on the outside of the connecting column due to the adsorption force, so that the protective plate moves from the top of the protective frame to the bottom of the fixed frame. At this time, the top of the protective frame is open. During the weeding process of the blade, the weeds entering the protective frame are moved out through the opening to prevent the weeds from gathering in the protective frame and entangled on the outside of the blade to affect the use of the blade. At the same time, it is prevented that the weeds gather to increase the wear of the blade, thereby improving the service life of the blade.

[0017] 2. In the intelligent weeding robot operating system of the example of the present invention, after the protective plate moves to the bottom of the fixed frame, the exhaust fan continues to exhaust air through the exhaust port on the side of the protective plate, so that the weeds in the protective frame are attracted and moved by the air flow, and the weeds are assisted to separate from the protective frame. The protective net is provided to protect the exhaust fan installed in the protective plate to prevent the weeds from entering the fixed frame and affecting the use of the exhaust fan.

[0018] 3. In the intelligent weeding robot operating system of the example of the present invention, the airflow extracted by the exhaust fan is discharged through the air outlet, and the collecting cover installed on the side of the fixed frame collects the airflow discharged from the air outlet, so that the airflow is gathered and then discharged through the air duct, and the airflow ejected through the air duct acts on the end of the cleaning blade, so that the cleaning blade rotates to clean the weeds gathered at the protective net, and the cleaning blade arranged in an arc structure is easy to push the weeds to move to the outside of the protective plate, so that the weeds are easy to detach from the bottom of the protective plate.

[0019] 4. In the intelligent weeding robot operating system of the example of the present invention, when the protective disk moves upward, the positioning rod installed on the side of the positioning frame drives the connecting rope to move, and the connecting rope drives the protective plate to rotate and open it. When the weeding robot is about to collide with a fruit tree, the fruit tree applies a force to the protective plate to rotate and reset it. When the protective plate rotates and resets, the protective plate drives the positioning rod to move in the positioning frame through the connecting rope, and the positioning nut at the end of the positioning rod squeezes the positioning spring, and the elastic supporting force of the positioning spring is used to offset part of the impact, thereby avoiding malfunction caused by the weeding robot colliding with the fruit tree and protecting the blade at the same time.

[0020] 5. In the intelligent weeding robot operation system of the example of the present invention, the spiral blades are driven to rotate during the rotation of the driving shaft. The spiral blades squeeze the coolant in the positioning cylinder into the liquid inlet pipe, and the coolant enters the protective box through the liquid inlet pipe. Under the temperature conduction effect of the heat conduction plate, the coolant exchanges heat with the heat generated when the motor is working, which has a cooling effect on the motor. After flowing in the flow cavity, the coolant flows back to the positioning cylinder through the reflux pipe. The heat dissipation fins arranged on the outside of the positioning cylinder assist the coolant in dissipating heat and cooling. The coolant circulates and exchanges heat with the motor, which is convenient for the cooling treatment of the motor. The spiral blades also have a mixing effect during the process of squeezing the coolant flow, which is convenient for the heat dissipation of the coolant. BRIEF DESCRIPTION OF THE DRAWINGS
