Description

Technical Field

[0001] This utility model relates to the field of weeding robots, and in particular to a cutting blade for an intelligent weeding robot. Background Technology

[0002] Intelligent weeding robots are innovative agricultural devices that utilize advanced technologies such as optical, ultrasonic, and infrared sensors to monitor ground conditions in real time and accurately identify the differences between weeds and crops. Through Internet of Things (IoT) technology, the data collected by the sensors is transmitted in real time to a central control system. After analysis and processing, the robot can accurately determine the distribution of weeds, thereby implementing targeted weeding operations.

[0003] Intelligent weeding robots are equipped with built-in smart algorithms that dynamically adjust and optimize weeding strategies based on sensor and historical data. These algorithms can also automatically adjust the frequency and intensity of weeding according to the crop's growth cycle and the weed's growth patterns, thereby improving weeding efficiency and effectively protecting crops. Furthermore, many intelligent weeding robots are also equipped with high-definition cameras and AI image recognition technology, enabling them to more accurately identify weeds and crops, further reducing the risk of accidental crop damage.

[0004] In practical applications, when intelligent weeding robots use a blade disc for weeding, although the disc design can cover a wide weeding area, some problems still exist in the process of adjusting the position through the sliding mechanism. Specifically, while the sliding mechanism theoretically allows for flexible adjustment of the blade position to adapt to the needs of different lawns or crop areas, in actual operation, this adjustment is often not precise or stable enough. Especially when the blades are in contact with the moving wheels, the interaction force between them can easily damage the moving wheels, which not only increases maintenance costs but also affects the overall lifespan of the robot.

[0005] Inconvenient height adjustment is also a significant problem faced by intelligent weeding robots. In practical use, users may need to adjust the blade height according to the growth of the lawn or crops to ensure effective weeding. However, existing height adjustment mechanisms are often complex and not intuitive, adding an extra operational burden to users. Furthermore, the precision of height adjustment is limited, making it difficult to meet the needs of some delicate tasks. Utility Model Content

[0006] The main objective of this invention is to provide a cutting tool for an intelligent weeding robot, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A cutting blade for an intelligent weeding robot includes a robot body, side frames, shock absorbers, support feet, a walking motor, and wheels. Four side frames are located at the corners of the robot body. The support feet are mounted on the side frames via shock absorbers. The wheels are mounted on brackets at the bottom of the support feet, and the brackets are equipped with walking motors for driving the wheels. A sliding device is installed at the lower end of the robot body, and a protective shell is connected to the lower end of the sliding device. A height adjustment motor and a height adjustment bracket are installed at the lower end of the protective shell. The height adjustment motor is connected to the height adjustment bracket via a transmission assembly. An adjustment platform is installed on the height adjustment bracket, and a rotary motor is installed at the upper end of the adjustment platform. A connecting rod is connected to the output end of the rotary motor, and a cutting blade assembly is connected to the lower end of the connecting rod.

[0009] Furthermore, the sliding device includes a cylinder, a linear guide rail, and a slide table. The cylinder and the linear guide rail are both installed at the lower end of the robot body, the slide table is slidably mounted on the linear guide rail, and the output end of the cylinder is connected to the slide table.

[0010] Furthermore, the height adjustment bracket comprises a stabilizing plate, a screw, and a guide rod arranged in parallel. One side of the two stabilizing plates is fixedly connected by a support rod. The two ends of the screw are rotatably connected to the two stabilizing plates respectively. The upper and lower ends of the guide rod are fixedly connected to the two stabilizing plates respectively. The side of the adjustment platform is slidably connected to the guide rod, and the adjustment platform is fixedly connected to the nut fitted on the screw.

[0011] Furthermore, the transmission assembly includes a driven gear and a driving paper wheel. The driven gear is mounted on the upper end of the screw, and the driving gear, which meshes with the driven paper wheel, is mounted on the output shaft of the height adjustment motor.

[0012] Furthermore, the protective shell is fixedly connected to the bottom of the slide by bolts.

[0013] Furthermore, the rotary motor is fixed to the upper surface of the adjustment platform by bolts, and a reducer is provided between the rotary motor and the connecting rod. The reducer is installed on the lower end surface of the adjustment platform by bolts, and the connecting rod and the output end of the reducer are fixed by coupling and bolts.

[0014] Furthermore, the lower end of the connecting rod is a threaded portion, and the cutting blade assembly includes a connector and cutting wires. Multiple cutting wires are fixed to the connector, and the connector is threadedly connected to the threaded portion of the connecting rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The height adjustment mechanism, through the coordinated work of the height adjustment motor, height adjustment bracket and adjustment platform, can be adjusted according to the height of the grass. This adjustment not only ensures that the cutting blade can accurately cover the area that needs to be weeded, but also avoids the problem of uneven weeding caused by different grass heights.

[0017] 2. The cutting mechanism is driven by a rotary motor, enabling the cutting blade assembly to perform weeding operations efficiently. At the same time, the design of the connecting rod and the cutting blade assembly allows for adjustment of the cutting depth according to the height of the grass, thereby ensuring the best weeding effect.

[0018] 3. The combined effect of the height adjustment mechanism and the cutting mechanism also improves the adaptability and flexibility of the equipment, enabling it to easily handle grass of different heights and move flexibly in various terrains, thereby greatly improving the efficiency and effectiveness of weeding operations.
