Description

Technical Field

[0001] This invention belongs to the field of tillage technology and relates to a tillage and weeding device. Background Technology

[0002] The film-intercropping technology is an innovative, practical, efficient, and environmentally friendly dryland water-saving agricultural technology developed by the Shaanxi Northern Agricultural Water-Saving Technology Innovation Team. This technology addresses the realities of agricultural development and the ecological environment in the Loess Plateau arid region, taking into account the needs of agricultural development and the current water resource distribution in Yulin. It was developed over more than ten years through extensive field trials and research, making it suitable for the climate characteristics, soil features, and agricultural development trends of the Loess Plateau arid region in northern Shaanxi. This technology boasts significant advantages, including saving time and labor, conserving resources, suppressing weeds, achieving high yields through water conservation, and reducing white pollution. It efficiently integrates agronomic techniques with agricultural machinery, independently developing a rotary tillage-mulching-film-intercropping seeding machine, a multi-functional film-intercropping seeding machine, and a residual film recycling machine, meeting the sowing needs of various specialty crops and effectively improving cultivation efficiency. Meanwhile, the topsoil cultivation measures performed between rows during the corn growth period aim to break up soil compaction, regulate moisture, and promote root growth and seedling development. Current cultivation methods mostly use plows between corn rows, which severely damages the mulch film and therefore cannot be applied to inter-mulch cultivation. In addition, traditional cultivation methods have a small soil loosening range, which can only treat a part of the soil between rows and cannot clean the soil between plants in the same row. Summary of the Invention

[0003] In view of this, in order to solve the problem that current inter-tillage equipment cannot be applied to fields with film-grown cultivation, and that the range of soil loosening and weeding is small, the present invention provides an inter-tillage and weeding equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A weeding and tilling device includes a base frame and a drive unit. A rear wheel and a steering control frame are mounted on the base frame. The drive unit is connected to the rear wheel via a transmission. A steering head is rotatably mounted on the steering control frame, and a front wheel is mounted on the steering head. A cover is provided above the rear wheel on the base frame. Two opposing tilling components are rotatably mounted at the rear end of the base frame, and a support spring connects the two tilling components, allowing them to unfold in a V-shape. Each tilling component includes an outer shell, with notches on opposite sides of the two outer shells. Multiple weeders are rotatably mounted on the outer shell, with adjacent weeders connected via a first synchronous belt. Each weeder includes a rotating disc, with a rotating shaft and several loosening soil components fixedly connected to its upper and lower ends, respectively. The nail, rotating disk, and drive component are rotatably connected. Multiple plow frames are mounted on the bottom of the outer casing, each plow frame equipped with a plow blade. A mounting frame is fixedly mounted on the base frame. Mounting plates are mounted on both sides of each mounting frame, and four rectangular wheels are mounted on each mounting plate. A conveyor belt is wound around the four wheels. Limiting components are evenly spaced on the conveyor belt. Each limiting component includes a mounting ring fixed to the conveyor belt, and a rotating seat is rotatably mounted on the mounting ring. Limiting cones and guide blocks are mounted on the rotating seat. The spacing between the limiting cones corresponds to the spacing between corn plants. Guide components corresponding to the conveyor belt are mounted on both sides of the casing. Guide grooves are provided on the guide components, and these guide grooves align with the front end of the conveyor belt to guide the guide blocks. Based on the above technical solution, the present invention has also made the following improvements: Furthermore, a sleeve is provided at one end of the outer casing, and a first drive shaft is rotatably mounted inside the sleeve. A first drive wheel and a second drive wheel are respectively mounted at both ends of the first drive shaft. A second synchronous belt is provided between the first drive wheels on the two tillage components. The second drive wheel is connected to the rotating shaft on the adjacent weeder via the first synchronous belt. A second drive shaft is mounted on the base frame, and a first driven wheel is mounted at one end of the second drive shaft. The first driven wheel is connected to the rear wheel and the drive component. The other end of the second drive shaft is connected to the first drive shaft on any one of the tillage components. When the drive component drives the second drive shaft to rotate, it can simultaneously drive the rear wheel and the weeders on both tillage components to rotate. The structure is relatively compact, facilitating a reduction in the overall size of the equipment and enabling it to move between corn rows.

[0005] Furthermore, the rotating disk has an upward-curving soil-retaining ring on its edge. This soil-retaining ring prevents soil from falling onto the rotating disk when the weeder moves and rotates.

[0006] Furthermore, the driving component is a gasoline engine, with a drive wheel mounted on the output shaft of the gasoline engine. A drive belt is installed between the drive wheel and the first driven wheel. A drive frame is installed between the mounting bracket and the cover, and the driving component is fixedly mounted on the drive frame. This design facilitates use in mountainous areas and energy replenishment. Additionally, the gasoline engine's top placement prevents it from contacting the corn seedlings, allowing for a smaller base frame that can better navigate between corn rows.

[0007] Furthermore, the rear wheel drive is connected to a clutch. The input end of the clutch is connected to the first driven wheel via a transmission belt, and the output end of the clutch is connected to the rear wheel shaft. The clutch pedal is located on the base frame. By controlling the power transmission through the clutch, the movement of the equipment can be stopped instantly by cutting off the input of kinetic energy, improving the controllability of the equipment and preventing excessive damage to corn seedlings due to improper operation.

[0008] Furthermore, a front guide vane cover is installed on the steering head, and guide vanes are installed on both sides of the cover, with the guide vanes located on the outside of the conveyor belt. The front guide vane cover and guide vanes can guide the corn seedling leaves to prevent them from being caught in the front or rear wheels or the conveyor belt.

[0009] Furthermore, both the front and rear wheels are equipped with several anti-skid pads on their outer circumference. These anti-skid pads enhance grip, facilitating better movement in the field.

[0010] Furthermore, a cushion is installed at the top of the cover. Users can sit on it during operation to improve comfort and reduce labor intensity.

[0011] Furthermore, the guide member is L-shaped with a magnetic block installed at the bend. A hinge is connected to the end of the guide member that connects to the cover, and the guide member is connected to the cover via the hinge. The guide member can be pulled up to release the guide block, and the pulled-up guide member can be attracted to the cover by the magnetic block.

[0012] The beneficial effects of this invention are as follows: The driving and weeding device can be moved between corn rows to loosen the soil and remove weeds. At the same time, the two V-shaped tillage components have a wide range of soil loosening and weeding. When cleaning the land between corn rows, it can also clean between corn plants in the same row, with a wide tillage range. 2. During the loosening of soil and weeding, a limiting cone is inserted on one side of the corn seedling stem to limit and guide the cultivation component, which can prevent the cultivation component from contacting the corn stem during movement and prevent damage to the corn stem during cultivation.

Detailed Implementation

[0014] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0015] like Figure 1 , 2 As shown, a weeding and tillage device includes a base frame 1 and a drive unit 32. A rear wheel 16 and a steering control frame 11 are mounted on the base frame 1. The drive unit 32 is connected to the rear wheel 16 via a transmission connection. A steering head 12 is rotatably mounted on the steering control frame 11, and a front wheel 13 is mounted on the steering head 12. The steering head 12 controls the movement direction of the device. A cover 14 is provided above the rear wheel 16 on the base frame 1. Two opposing tillage components 6 are rotatably mounted at the rear end of the base frame 1. A support spring connects the two tillage components 6, allowing them to unfold in a V-shape to facilitate loosening the soil and weeding between corn rows.

[0016] like Figures 6-9 As shown, the tillage component 6 includes an outer shell 61. Each of the two outer shells 61 has a notch 611 on one opposite side. Multiple weeders 62 are rotatably mounted on the outer shell 61. Adjacent weeders 62 are connected by a first synchronous belt 64. Each weeder 62 includes a rotating disc 621. A rotating shaft 622 and several loosening nails 624 are fixedly connected to the upper and lower ends of the rotating disc 621, respectively. The rotating disc 621 is rotatably connected to the drive component 32. The rotating shaft 622 has a synchronous pulley 623 for mounting the first synchronous belt 64. The first synchronous belt 64 is installed between the synchronous pulleys 623 on two adjacent rotating discs 621. When the rotating disc 621 rotates, the loosening nails 624 at the bottom rotate around the center of the rotating disc 621, loosening the soil and simultaneously pulling weeds away from the soil. The weeds that fall to the ground dehydrate and die, thus achieving the purpose of weed control. Multiple plow frames 65 are installed on the bottom of the outer shell 61, and each plow frame 65 is equipped with a plow blade 66. After the plow blade 66 is moved and inserted into the soil, it is used to plow and loosen the soil.

[0017] like Figures 2-5As shown, a mounting frame 2 is fixedly installed on the base frame 1. Mounting plates 21 are installed on both sides of the mounting frame 2. Four rotating wheels 22 are installed on each mounting plate 21. The rotating wheels 22 are rectangularly distributed. A conveyor belt 23 is wound around the four rotating wheels 22. Limiting components are installed at equal intervals on the conveyor belt 23. The limiting components include mounting rings 24 fixed to the conveyor belt 23. Rotating seats 25 are rotatably installed on the mounting rings 24. Limiting cones 26 and guide blocks 27 are installed on the rotating seats 25. The spacing between the limiting cones 26 corresponds to the spacing between corn plants. Guide components 4 corresponding to the conveyor belt 23 are installed on both sides of the cover 14. The guide components 4 are provided with guide grooves 41. The guide grooves 41 are aligned with the front end of the conveyor belt 23 to guide the guide blocks 27. After the lower limiting cone 26 is inserted into the soil, the conveyor belt 23 moves automatically as the base frame 1 moves forward. As the conveyor belt 23 moves, the lowermost limiting cone 26 is pulled out of the soil. When the limiting member above the conveyor belt 23 approaches the guide member 4, the guide block 27 on the limiting member falls into the guide groove 41, ensuring that the limiting cone 26 descends vertically and inserts into the soil. Before the limiting cone 26 restricting the cultivation component 6 separates from the cultivation component 6, a new limiting cone 26 is inserted into the soil to facilitate subsequent restriction and guidance of the cultivation component 6. Since the corn is planted by a seeder with uniform spacing between plants, the spacing between adjacent limiting cones 26 corresponds to the spacing between corn plants. After matching the limiting cone 26 with the first corn plant, subsequent limiting cones 26 inserted into the soil will automatically match with the corn plants. The guide member 4 is L-shaped and has a magnetic block installed at the bend. The end of the guide member 4 that connects to the cover 14 is connected to a hinge, and the guide member 4 is connected to the cover 14 through the hinge. The guide member 4 can be pulled up to release the guidance of the guide block 27, and the pulled-up guide member 4 can be attracted to the cover 14 under the action of the magnetic block, so as to facilitate the matching of the limiting cone rod 26 with the corn plant.

[0018] Specifically, one end of the outer casing 61 is provided with a sleeve 63, and a first drive shaft 632 is rotatably mounted inside the sleeve 63. A first drive wheel 631 and a second drive wheel are respectively mounted on both ends of the first drive shaft 632. A second synchronous belt 72 is provided between the first drive wheels 631 on the two tillage components 6. The second drive wheel is connected to the rotating shaft 622 on the adjacent weeder 62 through the first synchronous belt 64. A second drive shaft 51 is mounted on the base frame 1, and a first driven wheel 52 is mounted on one end of the second drive shaft 51. The second drive shaft 51 is connected to the rear wheel 16 and the drive component 32. The other end of the second drive shaft 51 is connected to the first drive shaft 632 on any one of the tillage components 6. In this embodiment, a first helical gear 53 is installed at the end of the second drive shaft 51, and a second helical gear 54 meshing with the first helical gear 53 is installed on the base frame 1. A second drive wheel 55 is coaxially connected to the second helical gear 54. A third drive wheel 71 is installed on any one of the first drive shafts 632, and a third synchronous belt 57 connects the second drive wheel 55 and the third drive wheel 71. When the drive component 32 drives the second drive shaft 51 to rotate, it can simultaneously drive the rear wheel 16 and the weeders 62 on both tillage components 6 to rotate. The structure is relatively compact, facilitating a reduction in the overall size of the equipment and enabling it to move between corn rows.

[0019] Specifically, the rotating disk 621 has an upward-curving soil-retaining ring on its edge, which can prevent soil from falling onto the rotating disk 621 when the weeder 62 moves and rotates.

[0020] Specifically, the drive component 32 is a gasoline engine, and a drive wheel is installed on the output shaft of the gasoline engine. A drive belt 33 is installed between the drive wheel and the first driven wheel 52. A drive frame 31 is installed between the mounting frame 2 and the cover 14. The drive component 32 is fixedly installed on the drive frame 31, which is convenient for use in mountainous areas and for energy replenishment. At the same time, the gasoline engine is placed on top so that it does not come into contact with the corn seedlings, so as to better reduce the volume of the base frame 1 and better move between the corn rows.

[0021] Specifically, the rear wheel 16 is connected to a clutch. The input end of the clutch is connected to the first driven wheel 52 via a transmission belt 56, and the output end of the clutch is connected to the shaft of the rear wheel 16. The clutch pedal is located on the base frame 1. By controlling the power transmission through the clutch, the movement of the equipment can be stopped immediately by cutting off the input of kinetic energy, thereby improving the controllability of the equipment and preventing large-scale damage to corn seedlings due to improper operation.

[0022] Specifically, a front guide vane cover 172 is installed on the steering head 12, and guide vanes 171 are installed on both sides of the cover 14. The guide vanes 171 are located on the outside of the conveyor belt 23. The front guide vane cover 172 and the guide vanes 171 can guide the corn seedling leaves to prevent them from being caught in the front wheel 13 or the rear wheel 16 and the conveyor belt 23.

[0023] Specifically, the outer circumference of both the front wheel 13 and the rear wheel 16 is provided with several anti-skid pads to enhance grip and facilitate better movement in the field.

[0024] Specifically, a seat cushion 15 is installed at the top of the cover 14, which the user can sit on during operation to improve comfort and reduce labor intensity.

[0025] Specifically, the guide member 4 is L-shaped and has a magnetic block installed at the bend. The end of the guide member 4 that connects to the cover 14 is connected to a hinge, and the guide member 4 is connected to the cover 14 through the hinge. The guide member 4 can be pulled up to release the guidance of the guide block 27, and the pulled-up guide member 4 can be attracted to the cover 14 by the magnetic block.

[0026] When inter-row cultivation is required, the inter-row cultivation and weeding device is moved to the corn row without a bottom film. The limiting cone 26 is matched with the first corn stalk and inserted into one side of the corn stalk. During the matching, the guide 4 is pulled up. Before the limiting cone 26 is inserted into the soil, the conveyor belt 23 is manually moved to insert the first limiting cone 26 into the soil. Then the guide 4 is lowered. The device is then moved so that the subsequent limiting cones 26 will automatically match with the corn stalk. As the base frame 1 moves, the V-shaped unfolding inter-row cultivation component 6 is moved. During the movement, the drive component 32 drives the weeders 62 on the two inter-row cultivation components 6 to rotate. When the weeders 62 rotate, the loosening nails 624 on them rotate around the center of the rotating disk 621. While loosening the soil, they can also twist the weeds away from the soil. The plow blade 66 can also loosen the soil when it is movable. When the outer shell 61 of the tillage component 6 comes into contact with the limiting cone 26 inserted into the soil, it can force the tillage component 6 to close and bypass the limiting cone 26, thereby bypassing the corn stalk to prevent damage. Meanwhile, the soil loosening nail 624 and plow blade 66 on the weeder 62 are inserted to a shallow depth and have less soil resistance. Under the action of the support spring, the outer shell 61 can be slightly past the limiting cone 26 before unfolding again to cultivate between the corn plants.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
