Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a sugarcane cultivation ridge covering and harrowing device. Background Technology

[0002] The sugarcane cultivation process involves: ridging → fertilization → planting sugarcane seeds → covering with soil. Currently, to achieve high yields, sugarcane ridges are typically dug to a depth of over 60 centimeters. Covering these ridges requires more than twice the workload of traditional methods. Manual covering is time-consuming, labor-intensive, and inefficient. Existing, widely used covering equipment can only cover one ridge at a time. Furthermore, because the ridges are not straight along their length, manual observation is still required while the equipment is moving in a straight line. If the direction of travel deviates from the ridge's direction, the equipment is adjusted by directly rotating it or by deflecting the towing device to ensure good covering quality. This makes the covering work labor-intensive and highly susceptible to human error in determining the quality. Summary of the Invention

[0023] 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.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-4 The present invention provides a sugarcane cultivation ridge covering and harrowing device, comprising:

[0026] Workbench 1, with a herringbone-shaped covering rake 11 and two sets of side covering rakes 10 below it. The two sets of side covering rakes 10 are located on both sides of the herringbone-shaped covering rake 11. The herringbone-shaped covering rake 11 and the two sets of side covering rakes 10 are used to cover two cultivation ridges with soil at the same time. The two sets of side covering rakes 10 and the workbench 1 are respectively provided with spacing adjustment devices, which are used to adjust the distance between the side covering rakes 10 and the herringbone-shaped covering rake 11.

[0027] The frame 13 has several rollers 8 rotatably connected to its bottom, and the frame 13 is located below the workbench 1;

[0028] The correction component includes an offset adjustment component, a controller 3, and a vision recognition camera 4 located at the front end of the workbench 1. The offset adjustment component is located between the frame 13 and the workbench 1. The vision recognition camera 4 is used to capture video images in front of the workbench 1. The controller 3 is used to analyze the video images to determine whether there is an offset between the direction of travel and the extension direction of the cultivation ridge. The offset adjustment component is used to make timely reverse adjustments when the workbench 1 is offset.

[0029] The herringbone-shaped covering rake 11 is located in the middle of two adjacent cultivation ridges. Through its herringbone expansion structure, it covers the soil between the two cultivation ridges into the cultivation ridge as it moves forward. The side covering rake 10 is set at an angle, with its rear end close to the herringbone-shaped covering rake 11. During its movement, it covers the soil on both sides of the cultivation ridge into the cultivation ridge. The main function of the spacing adjustment component is to achieve the best soil covering effect by adjusting the spacing between the side covering rake 10 and the herringbone-shaped covering rake 11 when facing cultivation ridges of different widths. The visual recognition camera 4 captures and transmits video images to the controller 3. The controller 3 compares and analyzes the video images to quickly determine whether the moving direction of the workbench 1 has deviated from the extension direction of the cultivation ridge. The main function of the offset adjustment component is to correct the position of the herringbone-shaped covering rake 11 and the side covering rake 10 by offsetting left and right when the workbench 1 deviates. Overall, this invention can simultaneously cover two sets of cultivation ridges with soil, improving the efficiency of the project. At the same time, during the soil covering process, it can automatically correct the left and right directions when the direction of travel deviates from the direction of cultivation ridges, ensuring good soil covering quality while saving manpower.

[0030] To further optimize the solution, the visual recognition camera 4 uses a CCD camera for real-time image acquisition.

[0031] The solution is further optimized by installing a power supply 2 on the workbench 1. The power supply 2 can supply power to the spacing adjustment component, the offset adjustment component, the controller 3, and the visual recognition camera 4.

[0032] The scheme is further optimized. The offset adjustment component includes two sets of sliders 17. The two sets of sliders 17 are fixedly connected to the bottom of the workbench 1 at one end near the visual recognition camera 4 and the other end away from the visual recognition camera 4. The front and rear ends of the top of the frame 13 are respectively provided with slide grooves 27. The slide grooves 27 are perpendicular to the traveling direction of the frame 13. The two sets of slide grooves 27 are respectively rotatably connected to the third lead screws 26. The two sets of sliders 17 are respectively slidably connected in the two sets of slide grooves 27 and are respectively driven by the two sets of third lead screws 26. The frame 13 is fixedly connected to two sets of second motors 7. The two sets of second motors 7 are respectively driven by the two sets of third lead screws 26.

[0033] like Figure 3 and Figure 4 As shown, when the controller 3 determines, through the image captured by the visual recognition camera 4, that the travel direction of the workbench 1 has shifted to the left relative to the extension direction of the cultivation ridge, the controller will automatically control the two sets of second motors 7 to rotate. The rotation of the second motors 7 drives the slider 17 to shift to the right within the slide groove 27 via a threaded transmission. The rightward shift of the slider 17 causes the workbench 1 to shift to the right relative to the frame 13, thereby causing the herringbone-shaped covering rake 11 and the two sets of side covering rakes 10 to shift to the right synchronously relative to the cultivation ridge, achieving the purpose of automatic correction. When shifting to the right, the controller 3 controls the second motors 7 to reverse.

[0034] In a further optimized design, a through groove is provided at the top center of the workbench 1, perpendicular to the travel direction of the workbench 1. A fixed seat 5 is fixedly connected to the center of the through groove, and a central connecting rod 18 is fixedly connected vertically to the bottom of the fixed seat 5. A connecting plate 19 is fixedly connected to the bottom of the central connecting rod 18. A herringbone-shaped soil covering rake 11 is fixedly connected to the central connecting rod 18 through the connecting plate 19, with the tip of the herringbone-shaped soil covering rake 11 facing the travel direction of the workbench 1.

[0035] The scheme is further optimized. The two ends of the herringbone covering rake 11 are respectively hinged with tail plates 21. The tail plates 21 and the hinge shaft of the herringbone covering rake 11 are vertically set. The two sets of tail plates 21 are equipped with expansion drive components. The expansion drive components are used to adjust the opening angle of the two sets of tail plates 21. The two sets of tail plates 21 are used to adapt to the spacing between different cultivation ridges.

[0036] Further optimization of the scheme: the expansion drive component includes a second lead screw 22 that is horizontally rotatably connected to the rear end of the connecting plate 19. The second lead screw 22 is in the same direction of travel as the worktable 1. A moving block 24 is connected to the second lead screw 22. Support rods 23 are respectively hinged between the two sets of tail plates 21 and the two opposite side walls of the moving block 24. A knob 25 is fixedly connected to the end of the second lead screw 22 away from the connecting plate 19 on the same axis.

[0037] like Figure 3 As shown, due to the varying spacing between different cultivation ridges, to ensure that the soil can smoothly enter the cultivation ridges after the tip of the herringbone covering rake 11 is scooped up, pushed by the side wall of the herringbone covering rake 11, when the spacing between cultivation ridges is relatively large, the operator can turn the knob 25 in advance. This knob 25 drives the second lead screw 22 to rotate. The rotation of the second lead screw 22 drives the moving block 24 towards the connecting plate 19 via the thread. While moving, the moving block 24 pushes the tail plate 21 outward through the support rods 23 on both sides, causing the tail plate 21 to rotate around the axis of the herringbone covering rake 11. As the tail of the tail plate 21 moves closer to the cultivation ridges on both sides, it ensures that the soil can be smoothly pushed into the cultivation ridges. Similarly, when the spacing between cultivation ridges is relatively small, simply turn the knob 25 in the opposite direction.

[0038] The scheme is further optimized. The spacing adjustment component includes a slide rod 14 that is horizontally fixed between the fixed seat 5 and the side wall of the channel, and a first lead screw 15 that is horizontally rotatably connected between the fixed seat 5 and the side wall of the channel. The slide rod 14 and the first lead screw 15 are perpendicular to the travel direction of the workbench 1. A first motor 6 is fixedly connected to the workbench 1. The first motor 6 is driven by the first lead screw 15. A sliding seat 16 is slidably connected to the slide rod 14. The sliding seat 16 is driven by the first lead screw 15. The side covering rake 10 is set below the sliding seat 16.

[0039] like Figure 1 and Figure 2 As shown, since the widths of different cultivation ridges vary, when dealing with environments with wider cultivation ridges, the controller 3 can control the rotation of two sets of first motors 6. The rotation of the two sets of first motors 6 drives the rotation of two sets of first lead screws 15. When the two sets of first lead screws 15 rotate, they drive the sliding seat 16 to move outwards from the worktable 1 through threaded transmission. This causes the sliding seat 16 to drive the side covering rake 10 away from the herringbone covering rake 11, increasing the distance between them to accommodate wider cultivation ridges. Similarly, by controlling the first motor 6 to reverse, the side covering rake 10 can move closer to the herringbone covering rake 11, decreasing the distance between them to accommodate narrower cultivation ridges.

[0040] In a further optimized design, an external connecting rod 9 is vertically fixedly connected to the lower part of the sliding seat 16, and the bottom of the external connecting rod 9 is fixedly connected to the side wall of the side covering rake 10 away from the herringbone covering rake 11.

[0041] In a further optimized design, several external connecting rods 28 are vertically fixedly connected to the bottom of the frame 13, and internal connecting rods 30 are vertically slidably connected to the bottom of the external connecting rods 28 respectively. Several rollers 8 are rotatably connected to the bottom of the internal connecting rods 30 respectively. A bearing plate 20 is fixedly connected to the side wall of the internal connecting rod 30, and an electric telescopic rod 29 is fixedly connected between the bearing plate 20 and the frame 13.

[0042] like Figure 4 As shown, a set of rollers 8 are respectively installed at each of the four corners of the frame 13. The rollers 8 are connected to the frame through an outer connecting rod 28 and an inner connecting rod 30. The rollers 8 are located on the outside of the frame to help prevent the rollers from crushing the cultivation ridges.

[0043] During the soil covering process, to ensure a good covering effect, the depth of the herringbone covering rake 11 and the side covering rake 10 can be controlled. The amount of soil pushed into the cultivation ridge can be changed by changing the amount of soil turned over by the rake. Specifically, when it is necessary to reduce the depth of soil covering, the electric telescopic rod 29 can be extended by the controller 3. The extension of the electric telescopic rod 29 pushes the inner connecting rod 30 outward to extend the outer connecting rod 28 through the bearing plate 20, thereby raising the height of the frame 13. When it is necessary to increase the depth of soil covering, it is only necessary to shorten the length of the electric telescopic rod 29.

[0044] In a further optimized design, a towing bar 12 is hinged to the front end of the frame 13, which is used to connect to agricultural towing equipment.

[0045] The main function of the towing bar 12 is to facilitate the connection between the vehicle frame 13 and the agricultural towing equipment.

[0046] The working process of this embodiment is as follows: The frame 13 is connected to the towing device via the towing rod 12. The expansion angle between the two sets of tail plates 21 is adjusted to a suitable value by rotating the knob 25. The controller 3 controls the first motor 6 to rotate, adjusting the distance between the side covering rake 10 and the herringbone covering rake 11. The towing device is started to drive the covering rake device of the present invention to perform soil covering operation. During the soil covering process, the visual recognition camera 4 captures video images of the cultivation ridge in front of the workbench 1 in real time and transmits the video images to the controller 3. The controller 3 analyzes the video images to monitor whether the travel direction of the workbench 1 has deviated from the extension direction of the cultivation ridge. When a deviation occurs, the controller 3 controls the second motor 7 to drive the workbench 1 to deviate in the opposite direction, thereby driving the side covering rake 10 and the herringbone covering rake 11 to deviate and correct synchronously relative to the cultivation ridge to ensure a good soil covering effect.
