Description

Technical Field

[0001] This utility model relates to the field of robotics, specifically to a cotton-picking robot. Background Technology

[0002] With the development of agricultural modernization, the efficiency and precision of cotton harvesting have become increasingly important. Cotton harvesting robots, as an innovative achievement in agricultural technology, aim to achieve rapid and accurate cotton harvesting through automation. This can significantly reduce the labor intensity of manual harvesting, improve harvesting efficiency, effectively meet the cotton industry's demand for efficient harvesting operations, and promote agricultural production towards intelligence and mechanization.

[0003] However, existing cotton-picking robots have some problems in terms of external structure. For example, the external structure of the robot's adsorption device is relatively simple. During the picking process, it is easily interfered with by cotton leaves, cotton branches and other debris, which leads to reduced adsorption efficiency or even blockage of the adsorption port, affecting the smooth progress of the overall picking work. Utility Model Content

[0004] The purpose of this invention is to provide a cotton-harvesting robot to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cotton-picking robot, comprising a robot body, a sleeve disposed at the lower part of the robot body, an adsorption hopper slidably disposed on the inner wall of the lower part of the sleeve, and further comprising:

[0006] Multiple sets of arc-shaped scrapers are installed inside the adsorption tube hopper;

[0007] The fixing ring is located inside the sleeve. When the adsorption tube is moved upward by the electric telescopic rod, the push assembly installed on the upper part of the adsorption tube pushes the column installed at the lower end of the fixing ring to rotate. The column drives the arc-shaped scraper to rotate from the state of being in contact with the inner wall of the adsorption tube to the state of being close to the center of the adsorption tube, so as to clean the blockage inside the adsorption tube as it moves upward.

[0008] As a further description of the above technical solution: the pushing assembly includes a first gasket fixed to the inner groove of the upper part of the adsorption tube bucket, a second gasket connected to the upper end of the first gasket by a spring, a vertical rod fixed to the upper end of the second gasket, and the second gasket and the vertical rod sliding against the inner groove of the adsorption tube bucket.

[0009] As a further description of the above technical solution: a protruding strip is fixed on the inner side of the upper part of the vertical rod, and a metal wire is connected between the first gasket and the second gasket.

[0010] As a further description of the above technical solution: the upper end of the column is integrally formed with a rotating block, which is rotatably connected to the fixed ring.

[0011] As a further description of the above technical solution: a spiral groove is provided on the outer surface of the column, and the convex strip slides in a directional manner along the spiral groove track. When the adsorption tube rises, the convex strip cooperates with the spiral groove to push the column to rotate.

[0012] As a further description of the above technical solution: the lower end of the electric telescopic rod passes through the fixing ring and is connected to the adsorption tube bucket.

[0013] The cotton-harvesting robot provided by this utility model, as described above, has the following beneficial effects:

[0014] 1. This cotton-harvesting robot addresses the common problem of clogged suction tubes with cotton and other debris during the harvesting process by incorporating a unique cleaning structure. During the retraction of the suction tube by the electric telescopic rod, a series of ingenious structural elements, such as the pusher assembly rotating the column and the column driving the arc-shaped scraper to rotate from a position against the inner wall of the suction tube to a position closer to the center, clear the blockages inside the suction tube. This ensures the suction tube remains unobstructed, effectively preventing interruptions in cotton harvesting due to blockages, greatly guaranteeing the continuity of the harvesting process, and improving harvesting efficiency.

[0015] 2. In this cotton-picking robot, the second pad and the vertical rod in the pushing component slide against the inner groove of the adsorption tube, ensuring the stability of the component's movement. The column is rotatably connected to the fixed ring through a rotating block, providing stable support for the rotation of the arc-shaped scraper. At the same time, the metal wire connecting the first and second pads, as well as the compression and tension control of the spring at specific stages, enable the entire cleaning structure to work stably under different working conditions, ensuring that the arc-shaped scraper can accurately return to its original position, avoiding affecting cotton adsorption and collection. The overall structure is stable and the operation is reliable, reducing the equipment failure rate. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figures 1-5 This utility model embodiment provides a cotton-harvesting robot technical solution: it includes a robot body 1, a sleeve 2 disposed at the lower part of the robot body 1, and an adsorption tube 3 slidably disposed on the lower inner wall of the sleeve 2, and further includes:

[0026] Multiple sets of arc-shaped scrapers 4 are installed inside the adsorption tube hopper 3;

[0027] The fixing ring 5 is located inside the sleeve 2. When the adsorption tube 3 is moved upward by the electric telescopic rod, the pusher assembly 6 installed on the upper part of the adsorption tube 3 pushes the column 7, which is rotated at the lower end of the fixing ring 5, to rotate. The column 7 drives the arc-shaped scraper 4 from the state of being in contact with the inner wall of the adsorption tube 3 to the state of being close to the center of the adsorption tube 3, so as to clean the blockage inside the adsorption tube 3 in conjunction with the upward movement of the adsorption tube 3. During the cotton harvesting process, the adsorption tube 3 may be blocked by cotton and other debris. When the electric telescopic rod moves the adsorption tube 3 upward, the pusher assembly 6 will trigger a series of subsequent actions. The purpose is to clean the blockage inside the adsorption tube 3 by rotating the arc-shaped scraper 4, so as to ensure that the cotton harvesting work can continue.

[0028] In another embodiment of this utility model, preferably, the pushing component 6 includes a first gasket 61 fixed to the upper inner groove of the adsorption tube 3. A second gasket 63 is connected to the upper end of the first gasket 61 via a spring 62. A vertical rod 64 is fixed to the upper end of the second gasket 63. The second gasket 63 and the vertical rod 64 slide against the inner groove of the adsorption tube 3. A protrusion 65 is fixed to the inner side of the upper part of the vertical rod 64, and a metal wire 66 connects the first gasket 61 and the second gasket 63. When the adsorption tube 3 moves upward, it drives the pushing component 6 to move upward as a whole. The second gasket 63 and the vertical rod 64 slide within the inner groove of the adsorption tube 3, ensuring the stability of the component's movement. The metal wire 66 connects the first gasket 61 and the second gasket 63, playing a specific role during the rising and falling of the adsorption tube 3, preventing the spring 62 from being overstretched or compressed.

[0029] In another embodiment of the present invention, preferably, a rotating block 9 is integrally formed on the upper end of the column 7, and the rotating block 9 is rotatably connected to the fixed ring 5; the rotating block 9 and the fixed ring 5 are rotatably connected, so that the column 7 can rotate on the fixed ring 5, providing a structural basis for the column 7 to drive the arc-shaped scraper 4 to rotate in the future.

[0030] In another embodiment of this utility model, preferably, the outer surface of the column 7 is provided with a spiral groove 10, and the protrusion 65 slides directionally along the track of the spiral groove 10. When the adsorption tube 3 rises, the protrusion 65 cooperates with the spiral groove 10 to push the column 7 to rotate. The rise of the adsorption tube 3 drives the pusher assembly 6 to move upward, thereby causing the protrusion 65 to slide directionally within the spiral groove 10. According to the special structure of the spiral groove 10, the sliding of the protrusion 65 will push the column 7 to rotate, realizing the power transmission of changing the arc-shaped scraper 4 from a state of adhering to the inner wall to a state of approaching the center.

[0031] In another embodiment of this utility model, preferably, the lower end of the electric telescopic rod passes through the fixing ring 5 and is connected to the adsorption tube 3; through this connection method, the electric telescopic rod can stably drive the adsorption tube 3 to move up and down within the sleeve 2, providing a power source for the entire action of clearing blockages.

[0032] When working, the staff starts the equipment, the adsorption tube 3 extends downward, and the cotton picking robot collects cotton through the adsorption tube 3. Specifically, the cotton is adsorbed through the negative pressure structure inside the robot equipment, and the cotton enters the robot body 1 through the adsorption tube 3.

[0033] During the process of the electric telescopic rod driving the adsorption tube 3 to recover, its lower end rod body passes through the fixing ring 5 and pushes the adsorption tube 3 to move upward. As the adsorption tube 3 moves upward, the first gasket 61, the second gasket 63, and the vertical rod 64 in the upper inner groove of the adsorption tube 3 also move upward. The second gasket 63 and the vertical rod 64 slide against the inner groove of the adsorption tube 3, and at the same time, the protrusion 65 on the upper inner side of the vertical rod 64 also moves.

[0034] The rotating block 9, integrally formed at the upper end of the column 7, is rotatably connected to the fixed ring 5. The outer surface of the column 7 is provided with a spiral groove 10. When the adsorption tube 3 rises, the protrusion 65 slides along the track of the spiral groove 10, thereby cooperating with the spiral groove 10 to push the column 7 to rotate. When the column 7 rotates, the connecting rod 8 drives the arc-shaped scraper 4 to rotate from the state of being in contact with the inner wall of the adsorption tube 3 to the state of being close to the center of the adsorption tube 3. As the adsorption tube 3 continues to move upward, the arc-shaped scraper 4 cleans the blockage inside the adsorption tube 3 to ensure that the adsorption tube 3 is unobstructed, so as to facilitate the smooth progress of subsequent cotton picking.

[0035] It is worth noting that when the convex strip 65 reaches the top of the spiral groove 10 track, the adsorption tube 3 continues to rise. At this time, the spring 62 is compressed, so that the arc-shaped scraper 4 remains in the same position. Moreover, since the metal wire 66 connects the first pad 61 and the second pad 63, the spring 62 will not be stretched when the adsorption tube 3 moves downward, ensuring that the arc-shaped scraper 4 returns to its original position and avoids affecting the adsorption and collection of cotton.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
