[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides, for example Figure 1-9The illustrated intelligent cotton topping mechanism with multiple telescopic arms includes a frame 100. The frame 100 has two mounting slots, a first 101 and a second 102, extending from the center to both sides. The width of the first mounting slot 101 is smaller than the width of the second mounting slot 102. A double-arm topping mechanism 300 is installed in the first mounting slot 101, and a four-arm topping mechanism 400 is installed in the second mounting slot 102. Both the double-arm topping mechanism 300 and the four-arm topping mechanism 400 are used for mechanical topping of cotton. The four-arm topping mechanism 400 is composed of two double-arm topping mechanisms 300 horizontally spliced ​​together. There are two sets of both the double-arm topping mechanism 300 and the four-arm topping mechanism 400, with each set having two topping mechanisms. These two sets of mechanisms can be combined to form twelve topping mechanisms, which can match the current row width of cotton planting and can effectively and quickly complete the topping process. The cotton topping operation also includes a vision recognition component 500 and an electronic control component 200 installed at the top center of the frame 100. The vision recognition component 500 is fixedly installed on the side wall of the frame 100 and is used to identify the spatial position of the cotton top. The electronic control component 200 is used to receive and process the recognition signal from the vision recognition component 500 and generate a topping execution signal, which is transmitted to the double-arm topping mechanism 300 and the four-arm topping mechanism 400. The vision recognition component 500 identifies the spatial position of the cotton top and converts it into coordinates in the Cartesian coordinate system. After data processing, the data is transmitted to the electronic control component 200. The electronic control component 200 processes the information and generates a topping execution signal, which is transmitted to the double-arm topping mechanism 300 and / or the four-arm topping mechanism 400 to perform the cotton topping operation. This can achieve accurate and rapid positioning in the cotton topping operation, reduce the missed detection rate of cotton topping, and improve the accuracy and efficiency of the topping operation.

[0045] It should be noted that the double-arm jacking mechanism 300 includes a jacking execution mechanism and a jacking position adjustment mechanism. The jacking execution mechanism is used for jacking the cotton top, and the jacking position adjustment mechanism is used to drive the jacking execution mechanism to move laterally and vertically for spatial position adjustment. Based on the information transmitted by the electronic control component 200, the jacking position adjustment mechanism adjusts the position of the jacking execution mechanism to accurately reach the cotton jacking position, and then the jacking execution mechanism actuates to perform the jacking operation on the cotton top. This automatic adjustment and jacking process results in high work efficiency and high jacking position accuracy. The jacking execution mechanism includes... The device includes a topping blade cover 413 and a topping motor cover 415 fixedly connected to the top of the topping blade cover 413. The inner side of the topping blade cover 413 is provided with a rotatable topping blade 414, which is used to cut the top of the cotton. The topping motor cover 415 is fixedly installed with a topping motor for driving the topping blade 414 to rotate. In this embodiment, when the topping blade cover 413 moves down and contacts the top of the cotton, the leaves near the top of the cotton can be pushed away by the topping blade cover 413 to protect the plant. Then, the topping motor drives the topping blade 414 to rotate to achieve the topping operation of the cotton top.

[0046] In a preferred embodiment, the top-mounting position adjustment mechanism includes a vertical toothed plate 401 perpendicular to the frame 100, a connecting seat 403, and a horizontal toothed plate 402 perpendicular to the vertical toothed plate 401. The side wall of the vertical toothed plate 401 is provided with a mounting slide 417 that can move vertically along the side wall of the vertical toothed plate 401. The connecting seat 403 is fixedly connected to the side of the mounting slide 417 away from the vertical toothed plate 401. Above the mounting slide 417 is a vertical gear 404 that meshes with the toothed outer wall of the vertical toothed plate 401. A vertical drive motor 405 for driving the vertical gear 404 to rotate is fixedly mounted on the top of the connecting seat 403. The horizontal toothed plate 402 is located at the bottom inner side of the connecting seat 403 and can move horizontally along the inner side of the connecting seat 403. Below the connecting seat 403 is a horizontal gear 406 that meshes with the toothed outer wall at the bottom end of the horizontal toothed plate 402. A horizontal drive motor 407 is fixedly mounted on the bottom of the connecting seat 403. 07 is used to drive the horizontal gear 406 to rotate. One end of the connecting seat 403 is fixedly connected to the end face of the topping motor cover 415. In this embodiment, the connecting seat 403 is bent in an alternating manner on both sides, with one side bent upward and the other side bent downward, which facilitates the installation of the horizontal drive motor 407 and the vertical drive motor 405. At the same time, it satisfies the requirement that the horizontal drive motor 407 and the vertical drive motor 405 drive the rotation of the horizontal gear 406 and the vertical gear 404 respectively. Moreover, the setting of the connecting seat 403 integrates the horizontal adjustment and the vertical adjustment into one unit. With the closed-loop motor system on it, the horizontal gear 406 and the vertical gear 404 can drive the topping actuator to adjust the horizontal and vertical positions by rotating clockwise or counterclockwise respectively. Not only is the position adjustment accurate, but the damage rate to the plant can also be minimized. Thus, the cotton topping operation can be positioned efficiently and accurately, making the topping mechanism more perfect and better meeting market demands.

[0047] Furthermore, guide slides 408 are fixedly connected to both sides of the bottom end of the connecting seat 403. First auxiliary pulleys 409 are rotatably connected to the inner walls of both sides of the guide slides 408. Second auxiliary pulleys 411 are rotatably connected to both ends of the connecting seat 403 and above the guide slides 408. The transverse toothed plate 402 is movably inserted between the first auxiliary pulleys 309 and the second auxiliary pulleys 411. The guide slides 408, together with the first auxiliary pulleys 309 and the second auxiliary pulleys 411 on the connecting seat 403, can limit and guide the transverse toothed plate 402. This not only reduces the frictional resistance of the transverse toothed plate 402 during horizontal movement and reduces energy consumption, but also enhances the stability of the relative movement between the connecting seat 403 and the transverse toothed plate 402, making the whole more compact and stable, and with high operating quality.

[0048] Meanwhile, a large block 410 protruding from the side of the guide slide 408 is provided on the side of the connecting seat 403 facing the top-attacking actuator. A spring plate 416 is fixedly provided on the top of the top of the top of the side of the top-attacking motor cover 415 facing the transverse toothed plate 402. The top-attacking motor cover 415 and the large block 410 are located on the same horizontal plane. The large block 410 cooperates with the spring plate 416. When the end of the transverse toothed plate 402 moves to the position of the connecting seat 403, the large block 410 is engaged in the spring plate 416, which buffers and limits the continued transverse movement of the transverse toothed plate 402. At the same time, it can also buffer the transverse movement of the toothed plate 402. The toothed plate 402 at its outermost end serves as an auxiliary locking mechanism, thereby maintaining the stability of the current storage position. A buffer block 412 protruding from the side of the guide slide 408 is fixedly connected to the side of the connecting seat 403 opposite to the top-loading actuator. A baffle is fixedly connected to the top end of the transverse toothed plate 402. The buffer block 412, in conjunction with the baffle, also limits the transverse toothed plate 402 in the other lateral direction of movement, preventing excessive movement and potential detachment. A straight passage connecting the two ends of the vertical toothed plate 401 is provided on the side facing the mounting slide 417. On the side of the mounting slide 417 opposite the vertical toothed plate 401, multiple rotatable limiting pulleys 419 are spaced from top to bottom in the straight channel 418. The limiting pulleys 419 are movably inserted into the inside of the straight channel 418. The limiting pulleys 419 are divided into two groups and symmetrically arranged, capable of engaging with the protruding strip-shaped positions on both sides of the inner wall of the straight channel 418. This limits the lateral position of the mounting slide 417, preventing it from laterally disengaging from the vertical toothed plate 401. Simultaneously, the rolling of the limiting pulleys 419 reduces the frictional resistance between the two, enhancing the installation... Stability of the slide 417 during relative movement: A spring plate 420 is fixedly connected to the top of the side of the slide 417 away from the vertical toothed plate 401, and an L-shaped stop 421 is fixedly connected to the top of the side wall of the vertical toothed plate 401. The top of the spring plate 420 is bent and extends above the slide 417. The spring plate 420 and the L-shaped stop 421 cooperate to buffer and limit the movement of the slide 417 to the top position of the vertical toothed plate 401, and also play a locking role, making the slide 417 more stable when positioned at the top position of the vertical toothed plate 401.

[0049] In a preferred embodiment, the visual recognition component 500 includes a binocular recognition camera 502 for identifying the spatial position of the cotton top. A mounting base 501 for supporting the binocular recognition camera 502 is fixedly connected to the side wall of the frame 100. A cable management unit 503 is fixedly connected to the top of the mounting base 501. The cable management unit 503 is used for organizing and protecting the cables on the binocular recognition camera 502. Through the support of the mounting base 501 and the collection and organization of the cables by the cable management unit 503, the binocular recognition camera 502 can stably identify the spatial position of the cotton top, improving positioning accuracy and simultaneously ensuring the overall... The top-mounting mechanism is more intelligent; furthermore, the electrical control component 200 includes an electrical control box fixedly installed at the top center of the frame 100, and an electrical control motherboard fixedly installed inside the electrical control box. The electrical control motherboard leads out communication cables and power supply cables to the double-arm top-mounting mechanism 300 and the four-arm top-mounting mechanism 400. The electrical control motherboard has a control program that can receive and analyze the coordinate information transmitted from the visual recognition component 500, and then generate corresponding top-mounting execution signals to transmit to the double-arm top-mounting mechanism 300 and / or the four-arm top-mounting mechanism 400, thereby achieving intelligent and efficient top-mounting operation of cotton tops and meeting the needs of long-term use.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
