Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weeding robots, in particular to an inter-row weeding execution mechanism of a farmland weeding robot. Background Art
[0002] Weeding robots are a technology with good application prospects in modern agriculture. They have significant advantages in saving labor and reducing the use of pesticides. Therefore, it is crucial to develop efficient and sustainable weeding robot weed removal supporting mechanisms to reduce the labor pressure of farmers and provide important conditions for effectively protecting crops. At present, domestic farmland planting is mainly small-scale planting, and many areas do not follow professional and standardized planting methods, so the application scenarios of farmland weeding robots are more complex and diverse. Under such conditions, when weeding in the field by weeding robots, it is usually due to the influence of the recognition defects of the weeding robots themselves, which can easily damage the crop plants during the weeding process, causing farmers to suffer large farmland losses and greatly reducing the overall weeding efficiency of the farmland. Therefore, it is necessary to further optimize the supporting mechanisms of weeding robots in the field to ensure the quality and efficiency of weeding. Utility Model Content
[0003] The utility model provides an inter-row weeding execution mechanism of a farmland weeding robot to solve the problems existing in the above background.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A weeding actuator for an agricultural weeding robot comprises a reducer connecting plate, guide rods are detachably connected vertically to both sides of the reducer connecting plate, a guide positioning plate is movably connected to one side of the guide rod away from the reducer connecting plate, the guide positioning plate is vertically connected to a connecting rod, and the connecting rod is also connected to a crescent knife.
[0006] Furthermore, a reducer connecting sleeve is provided on the top of the reducer connecting plate.
[0007] Furthermore, the bottom of the guide rod is sleeved with a guide sleeve, the guide sleeve is fixedly connected to the guide positioning plate, and the guide rod is slidably arranged inside the guide sleeve.
[0008] Furthermore, a spring is sleeved on the outer side of the guide rod between the guide sleeve and the reducer connecting plate, a grease groove is provided on the outer circular side of the guide rod located inside the guide sleeve, and an oil cup is provided on the outer side of the guide sleeve.
[0009] Furthermore, connecting ear plates are horizontally connected to both sides of the connecting rod, and the connecting rod is detachably connected to the guide positioning plate through the connecting ear plates, and the connecting rod is detachably connected to the crescent knife through the connecting ear plates.
[0010] Furthermore, the connecting rod is arranged in an "S" shape.
[0011] The utility model has the following beneficial effects:
[0012] The utility model provides an inter-row weeding execution mechanism of a farmland weeding robot, which is mainly composed of a reducer connecting plate, a connecting sleeve, a guide rod, an "S"-shaped connecting rod, a crescent blade, a lubricating oil cup and other components. By connecting a servo motor to a reducer, and then connecting the entire mechanism with a connecting sleeve through the reducer, power is provided to the mechanism, so that the weeding mechanism rotates with the speed output by the reducer, and at the same time the mechanism moves forward with the overall walking speed of the weeding vehicle, effectively achieving the weeding effect of the crescent blade rotating and moving forward while avoiding crop plants, significantly reducing the difficulty of weeding between crop plants, thereby improving the overall efficiency of weeding between crop plants, and solving the problem that when a weeding robot is currently used for weeding operations in the field, the weeding blade is often difficult to avoid crops due to the lack of a dedicated weeding blade control structure, and ultimately the crop plants are easily damaged while the weeds are cleared.
[0013] The setting of the spring in the utility model effectively ensures that when the connecting rod and the crescent knife rotate with the reducer and realize the "S"-shaped path weeding operation, the spring can be expanded and contracted as the terrain changes, thereby effectively ensuring the thoroughness of field ground weeding, thereby improving the overall quality of the weeding operation. At the same time, the spring also plays an axial buffering role. When the hardness of the farmland is too high or there are hard protrusions, the depth of the crescent knife set to penetrate into the soil is difficult to reach. In this way, the ground generates an axial force on the weeding mechanism, and the compression spring is compressed, thereby reducing the depth of the mechanism penetrated into the soil, thereby protecting the weeding mechanism.
[0014] In the utility model, a threaded hole is opened on the guide sleeve for installing an oil cup, and lubricating grease is added into the guide sleeve, which effectively reduces the friction resistance between the spring guide rod and the guide sleeve, thereby improving the overall service life of the weeding mechanism.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1-4 As shown, an inter-row weeding actuator of a farmland weeding robot includes a reducer connecting plate 1, a reducer connecting sleeve 7 is welded on the top of the reducer connecting plate 1, guide rods 3 are vertically threadedly connected to both sides of the reducer connecting plate 1, a guide positioning plate 4 is movably connected to the side of the guide rod 3 away from the reducer connecting plate 1, the guide positioning plate 4 is vertically connected to a connecting rod 5, and the connecting rod 5 is also connected to a crescent knife 6.
[0023] The bottom of the guide rod 3 is sleeved with a guide sleeve 8 , the guide sleeve 8 and the guide positioning plate 4 are welded and connected, and the guide rod 3 is slidably installed inside the guide sleeve 8 .
[0024] The outer side of the guide rod 3 between the guide sleeve 8 and the reducer connecting plate 1 is sleeved with a spring 2, and the outer circumferential side of the guide rod 3 located inside the guide sleeve 8 is also provided with a grease groove 10, and the outer side of the guide sleeve 8 is also installed with an oil cup 9.
[0025] Connecting ear plates 11 are horizontally welded on both sides of the connecting rod 5, and the connecting rod 5 is bolted to the guide positioning plate 4 through the connecting ear plates 11, and the connecting rod 5 is bolted to the crescent knife 6 through the connecting ear plates 11.

Under the condition that the servo motor of the weeding vehicle drives the rotation and matches the weeding vehicle to go straight in the field, the reducer drives the mechanism to realize the weeding operation of the "S"-shaped path on the field ground, effectively ensuring the weeding effect of the crescent knife 6 while rotating and moving forward while walking along the spiral trajectory, so that the weeding mechanism effectively avoids the crop plants 12, realizes high-quality weeding between the crop plants 12, thereby greatly reducing the difficulty of weeding between crop plants. Therefore, the mechanism has good practicality.
