A plateau meadow cutting and stripping device

Abstract

The present invention discloses a plateau meadow cutting and stripping device, comprising a mobile vehicle, a cutting mechanism, and a squeezing mechanism. The upper and lower cutters are arranged vertically in the cutting mechanism. After the lower cutter scoops up the turf, the squeezing mechanism can drive the upper cutter downward and press the turf scooped up by the lower cutter, thereby pressing the turf on the lower cutter. This avoids the loosening of the turf soil due to the lack of the function of pressing the scooped turf, and avoids the scattering of soil during transportation and transplantation. This is beneficial for protecting the meadow's attached matrix and root system, improving the meadow's survival rate, and helping to improve the efficiency of turf transportation. A first spring can cause the upper cutter to return to its original position after the pressure of the squeezing mechanism is removed, thereby ensuring the normal cutting function of the upper and lower cutters. The present invention achieves meadow cutting and stripping while simplifying the device structure and reducing maintenance costs. It can also adapt to uneven ground and cut and strip meadows without damage, achieving good forming effects and high work efficiency.

Description

Technical Field

[0001] The invention belongs to the technical field of soil and water conservation in alpine areas, relates to a meadow transplantation technology, and particularly relates to a plateau meadow cutting and stripping device. Background Art

[0002] Alpine meadows are a type of grassland that develops on plateaus and high mountains under cold environmental conditions. Their soils are primarily alpine meadow soils. Their vegetation is primarily composed of cold-tolerant perennial herbaceous plants, often accompanied by mesophilic perennial forbs. Construction projects inevitably damage alpine meadows, which are difficult to repair. Therefore, alpine meadows are typically stripped and conserved before construction begins, and then replanted afterward. Meadow stripping is the first step in effective alpine meadow conservation and ecological restoration.

[0003] Some patents have proposed ideas for devices for stripping alpine meadows, such as: Patent application number CN201921862765.0 discloses an alpine meadow drafting machine, which includes a body and a drafting structure. The body drives the drafting knife to make straight-line reciprocating cutting, and the lifting platform adjusts the drafting height. However, the body of the device is relatively bulky and has certain difficulties in transportation under field conditions; Patent application number CN201921866590.0 discloses an alpine meadow block forming tool, which includes a pressing plate, a pressing rod, a forming mold, etc., which solves the problem of low cutting efficiency of a single meadow block, but the depth of the mold depends on the thickness of the meadow, and the depth of the forming cavity needs to be repeatedly set; Patent application number C Patent N201921866626.5 discloses an alpine meadow cutter, which can automatically adjust the cutting depth according to the thickness of the alpine meadow soil, but it cannot be applied to a plane with a certain slope, and the soil in the meadow blocks is easy to fall off; Patent application number CN201921526670.1 discloses an alpine meadow transplanter, which includes a trolley frame, a meadow block forming mold, a first drive device, a second drive device and a shovel. The device ensures that the soil in the meadow blocks is not easy to fall off during the drafting and subsequent transplantation and conservation process, and the root system of the plants is better protected, but the draft angle is not less than 5°, and it is less suitable for the uneven surface of the plateau meadow.

[0004] As can be seen from the above, the existing alpine meadow stripping devices mainly include meadow weeding machines, meadow cutting machines and meadow transplanting machines, etc., which have the following three shortcomings: ① Some devices are relatively heavy and difficult to transport in the field. After cutting, they need to be manually shoveled horizontally with a hoe or shovel, which increases labor and stripping costs. ② When peeling, the shoveled turf cannot be compacted well. The soil of the shoveled turf is loose, which can easily cause the soil to scatter during transportation and transplantation, causing damage to the attached matrix and root system of the meadow and reducing the survival rate of the meadow. ③The existing device is equipped with a horizontal cutting blade, which has a poor effect on the formation of meadow blocks or even fails to form any blocks on uneven or sloped vegetation surfaces. Therefore, it is necessary to propose a new type of plateau meadow cutting and stripping device to overcome the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a plateau meadow cutting and stripping device to solve the problem that the existing alpine meadow stripping device cannot achieve an excellent compacting effect on the shoveled turf during stripping, the shoveled turf soil is loose, and it is easy to cause the soil to scatter during the transportation and transplantation process, which can easily cause damage to the meadow's attached matrix and root system, and reduce the meadow survival rate.

[0036] The plateau meadow cutting and stripping device proposed in the present invention has a novel and rational structure. The upper and lower cutters in the cutting mechanism are arranged vertically. After the lower cutter scoops up the turf, a squeezing mechanism drives the upper cutter downward and presses the turf scooped up by the lower cutter, effectively pressing the turf on the lower cutter. This prevents loosening of the turf soil due to a lack of compaction, and prevents soil scattering during transport and transplantation. This helps protect the meadow's attached substrate and root system, improves the meadow's survival rate, and contributes to improved turf transportation efficiency. A first spring resets the upper cutter upward after the pressure from the squeezing mechanism is removed, ensuring the normal cutting functions of the upper and lower cutters.

[0037] In some technical solutions of the present invention, a turf collection mechanism is also provided, wherein a limit plate is movably inserted in the slide groove of the lower cutter, and the front end of the limit plate is connected to the front end of the slide groove through a second spring. The traction mechanism can pull the limit plate backward relative to the lower cutter to transport the turf scooped up by the lower cutter to a mobile vehicle for collection. This solution realizes the shoveling, pressing and collecting of the turf at the same time, without the need for manual collection, which not only saves labor but also improves the work efficiency of meadow cutting and stripping.

[0038] In some technical solutions of the present invention, the turf collection mechanism and the above-mentioned squeezing mechanism share a set of driving motors. Through clever structural design, an orderly alternating linkage between the turf pressing function and the turf collection function is achieved, which is not only more compact in structure, but also conducive to improving work efficiency.

[0039] Existing devices use horizontal cutting blades, but when used on uneven or sloped surfaces, the resulting grass is poorly formed or even impossible to form. In some technical solutions, the present invention incorporates an adjustable drive mechanism that allows the upper, lower, and side cutters to rotate synchronously to accommodate varying slopes.

[0040] To sum up, the plateau meadow cutting and stripping device of the present invention realizes meadow cutting and stripping while simplifying the device structure and reducing maintenance costs. It not only has the turf pressing function and turf collecting function, but also can adapt to uneven ground and cut and strip meadows without damage. It has good molding effect and high work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] One of the purposes of the present invention is to provide a plateau meadow cutting and stripping device, which is mainly used to solve the problem that the existing alpine meadow stripping device cannot achieve an excellent compacting effect on the shoveled turf during stripping, and the shoveled turf soil is loose, which can easily cause the soil to scatter during the transportation and transplantation process, easily causing damage to the meadow's attached matrix and root system, and reducing the meadow survival rate.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Example 1

[0052] like Figures 1 to 4 As shown, this embodiment provides a plateau meadow cutting and stripping device, which mainly includes a mobile vehicle 1, a cutting mechanism and a squeezing mechanism. The cutting mechanism is arranged in front of the mobile vehicle 1. The cutting mechanism includes a lower cutter 16, an upper cutter 15, a positioning rod 14 and a first spring 17. The positioning rod 14 is movably connected to the bottom of the mobile vehicle 1. The first spring 17 is mounted on the positioning rod 14. The lower cutter 16 is slidably mounted on the bottom of the positioning rod 14 and abuts against the bottom of the first spring 17. The upper cutter 15 is slidably mounted on the top of the positioning rod 14 and abuts against the top of the first spring 17. The squeezing mechanism includes a pressing plate 13, a connecting mechanism and a driving mechanism. The pressing plate 13 is arranged above the upper cutter 15. The driving mechanism is connected to the pressing plate 13 through the connecting mechanism. The driving mechanism can drive the pressing plate 13 to press down the upper cutter 15, so that the upper cutter 15 presses the turf scooped up by the lower cutter 16. Generally, the front of the aforementioned mobile vehicle 1 is the moving direction of the mobile vehicle 1 when cutting the meadow.

[0053] In this embodiment, side cutters 21 are provided on both sides of the upper cutter 15 and the lower cutter 16 .

[0054] In this embodiment, the connecting mechanism mainly includes a first turntable 7, a connecting rod 9, a push rod 10, a sector gear 11 and a pressure rod 12. One side of the first turntable 7 is connected to the driving mechanism, and an eccentric pin is provided on the other side of the first turntable 7. The driving mechanism can drive the first turntable 7 to rotate; one end of the connecting rod 9 is hinged to the aforementioned eccentric pin; one end of the push rod 10 is hinged to the other end of the connecting rod 9; the sector gear 11 is rotatably installed on the mobile vehicle 1, and the sector gear 11 is connected to the other end of the push rod 10; the pressure rod 12 is provided with a rack that meshes with the sector gear 11, the top of the pressure rod 12 is in sliding fit with the mobile vehicle 1, and the bottom is connected to the pressure plate 13. Generally, the top of the pressure rod 12 passes through a fixed plate on the top of the mobile vehicle 1, and forms a sliding fit with the fixed plate. The fixed plate provides an installation place and guide for the pressure rod 12. In order to prevent the pressure rod 12 from falling off, a limit block can also be provided on the top of the pressure rod 12. Figure 2 As shown, the circular protrusion on the top of the pressure rod 12 is the aforementioned limit block.

[0055] In this embodiment, the aforementioned drive mechanism mainly includes a drive motor 2 and a first rotating wheel 3. The drive motor 2 is disposed in the mobile vehicle 1. One side of the first rotating wheel 3 is connected to the output end of the drive motor 2, and the other side is connected to the first turntable 7. The first turntable 7, the first rotating wheel 3, and the output shaft of the drive motor 2 are coaxially arranged. The drive motor 2 can drive the first turntable 7 to rotate via the first rotating wheel 3. The drive motor 2 is a servo motor, which drives the first turntable 7 to rotate, thereby driving the connecting rod 9 to rotate. The rotation of the connecting rod 9 drives the push rod 10 to rotate, thereby driving the sector gear 11 to rotate. The sector gear 11 is hinged to a fixed plate disposed on the top of the mobile vehicle to ensure stable rotation of the sector gear 11. The rotation of the sector gear 11 drives the push rod 10 to rise or fall.

[0056] This embodiment also includes a turf collection mechanism. The lower cutter 16 is provided with a chute, and a notch is formed on the upper surface of the lower cutter 16 to communicate with the chute. The turf collection mechanism includes a limit plate 19 and a traction mechanism. The limit plate 19 is movably inserted into the chute, and the front end of the limit plate 19 is connected to the front end of the chute via a second spring 20, allowing the limit plate 19 to move forward and backward along the chute relative to the lower cutter 16. The traction mechanism is connected to the rear end of the limit plate 19 and is used to pull the limit plate 19 backward relative to the lower cutter 16 to transport the turf scooped up by the lower cutter 16 to the mobile vehicle 1 for collection. The second spring 20 is used to pull the limit plate 19 back into the chute to reset the limit plate 19. Among them, the size of the limit plate 19 is adapted to the size of the slide groove. When the lower cutter 16 is in the correct cutting state, the limit plate 19 can just block the notch on the upper surface of the lower cutter 16 to provide support for the turf shoveled by the lower cutter 16. After the turf on the lower cutter 16 is pressed by the pressure plate 13, the limit plate 19 can be pulled backward relative to the lower cutter 16 by the traction mechanism to transport the turf shoveled by the lower cutter 16 to the mobile vehicle 1 for collection.

[0057] In this embodiment, the traction mechanism, also known as a pulling mechanism, comprises a second rotating wheel 5, a second rotating disc 8, and a pull rope 18. One side of the second rotating wheel 5 is rotatably connected to the mobile vehicle 1 via a rotating rod 6, and the second rotating wheel 5 is transmission-connected to the first rotating wheel 3 via a conveyor belt 4. The second rotating disc 8 is coaxially arranged with the second rotating wheel 5 and connected to the second rotating wheel 5. One end of the pull rope 18 is connected to the rear end of the limit plate 19, and the other end is wrapped around the side wall of the second rotating disc 8. When the drive motor 2 drives the first rotating disc 7 to rotate to press the pressure plate 13 downward, the pull rope 18 is unwound from the second rotating disc 8. When the drive motor 2 drives the first rotating disc 7 to reverse to reset the pressure plate 13, the second rotating disc 8 rewinds the pull rope 18 to pull the limit plate 19 backward relative to the lower cutter 16. In actual operation, the conveyor belt 4 is preferably a belt, and the first rotating wheel 3 and the second rotating wheel 5 are arranged vertically.

[0058] This embodiment further includes an adjustment drive mechanism connected to the top of the aforementioned positioning rod 14, which is used to drive the positioning rod 14 to rotate, so that the positioning rod 14 can drive the upper cutter 15 and the lower cutter 16 to rotate synchronously. Furthermore, it is preferred that the positioning rod 14 is set as a prismatic rod, and the upper cutter 15 and the lower cutter 16 are both provided with polygonal holes corresponding to the prismatic rod. For example, if the positioning rod 14 is a regular hexagonal prism rod, the polygonal holes provided on the upper cutter 15 and the lower cutter 16 are both regular hexagonal holes. The upper cutter 15 and the lower cutter 16 cooperate with the regular hexagonal prism rod through the regular hexagonal holes, so that the upper cutter 15 and the lower cutter 16 can only slide axially relative to the prismatic rod, but cannot rotate relative to the prismatic rod, thereby ensuring that when the adjustment drive mechanism drives the positioning rod 14 to rotate, the upper cutter 15 and the lower cutter 16 can rotate synchronously with the positioning rod 14. Generally, the bottom end of the positioning rod 14 is set through a fixed plate at the bottom of the mobile vehicle 1. After the bottom end of the positioning rod 14 passes through a fixed plate at the bottom of the mobile vehicle 1, it can be axially positioned by components such as nuts to prevent the positioning rod 14 from axially moving relative to the fixed plate at the bottom of the above-mentioned mobile vehicle 1. However, the positioning rod 14 can rotate relative to the fixed plate. For example, the part where the positioning rod 14 is connected to the fixed plate is set to a cylindrical surface, so that it can rotate relative to the fixed plate under the drive of the adjustment drive mechanism.

[0059] In this embodiment, the above-mentioned adjustment drive mechanism is arranged on a side of the mobile vehicle 1 near the drive motor 2, and mainly includes a rotating plate 23, a first gear, a second gear and a turning handle 22. The rotating plate 23 is rotatably connected to the inside of the mobile vehicle 1 and is connected to the top of the positioning rod 14. The first gear is connected to the rotating plate 23, and the second gear is meshed with the first gear. The turning handle 22 is rotatably installed on the top of the mobile vehicle 1 and is connected to the second gear. The above-mentioned adjustment drive mechanism and the positioning rod 14 together form a positioning mechanism. Manually rotating the above-mentioned turning handle 22 can drive the second gear to rotate. After the second gear is meshed with the first gear, it drives the first gear to rotate, thereby satisfying the first gear to drive the rotating plate 23 to rotate, thereby adjusting the rotation of the upper cutter 15, the lower cutter 16 and the side cutter 21. After the rotation is adjusted to the right position, the positioning rod 14 no longer rotates, thereby positioning the positioning rod 14.

[0060] The working principle of the plateau meadow cutting and stripping device in this embodiment is described in detail below:

[0061] During use, the movement of the mobile vehicle 1 drives the upper cutter 15 and the lower cutter 16 to move, so that the lower cutter 16 scoops up the turf. Subsequently, the drive motor 2 rotates forward to drive the first rotating wheel 3 to rotate. The rotation of the first rotating wheel 3 drives the first rotating disk 7 to rotate. The rotation of the first rotating disk 7 drives the connecting rod 9 to rotate. The rotation of the connecting rod 9 drives the push rod 10 to move. The movement of the push rod 10 drives the sector gear 11 to rotate. The rotation of the sector gear 11 drives the pressure rod 12 to move downward, thereby driving the pressure plate 13 to press the upper cutter 15. When the upper cutter 15 presses downward, it squeezes the first spring 17 and presses the turf inside the lower cutter 16, thereby compacting the soil. During the process of the upper cutter 15 pressing the turf, the pull rope 18 is in a relaxed state, and the limit plate 19 is inserted into the chute of the lower cutter.

[0062] When encountering grass with different slopes, turning the handle 22 drives the second gear to rotate, and the second gear engages with the first gear to drive the first gear to rotate, thereby driving the rotating plate 23 to rotate through the first gear, thereby adjusting the rotation of the upper cutter 15, the lower cutter 16 and the side cutter 21 to adapt to grass with different slopes.

[0063] Then the driving motor 2 is reversed to drive the first rotating wheel 3 to rotate in the opposite direction. The reverse rotation of the first rotating wheel 3 drives the conveyor belt 4 to rotate in the opposite direction, thereby driving the second rotating wheel 5 to rotate. The rotation of the second rotating wheel 5 drives the second turntable 8 to rotate, so as to reel in the pull rope 18 to straighten the pull rope 18 and pull the limit plate 19 to transfer and collect the turf inside the lower cutter 16 with high work efficiency.

[0064] As can be seen from the above, the plateau meadow cutting and stripping device of this embodiment utilizes the upper and lower cutters to scoop up the turf, and at the same time utilizes a drive motor to drive the first turntable to rotate, thereby driving the pressure plate to press down, thereby achieving the effect of pressing the soil on the scooped turf. At the same time, a conveyor belt is used to connect the second rotating wheel of the traction mechanism with the first rotating wheel of the squeezing mechanism, thereby achieving the effect of pulling the limit plate by the drive motor to collect the turf. The turf collection mechanism of this embodiment and the above-mentioned squeezing mechanism share a set of drive motors. Through the ingenious structural design, an orderly alternating linkage between the turf pressing function and the turf collection function is achieved. That is, when the pressure plate is pressed down, the pull rope is in a relaxed state. In the process of the pressure plate returning to its original position, the pull rope gradually straightens and pulls the limit plate. Such a design is not only more compact in structure, but also helps to improve work efficiency.

[0065] Existing devices use horizontal cutting blades, which can result in poor or even impossible grass cutter formation on uneven or sloped surfaces. This embodiment incorporates an adjustable drive mechanism that allows the upper, lower, and side cutters to rotate synchronously to accommodate varying slopes.

[0066] In summary, the plateau meadow cutting and stripping device of this embodiment realizes meadow cutting and stripping while simplifying the device structure and reducing maintenance costs. It not only has the turf pressing function and turf collecting function, but also can adapt to uneven ground and cut and strip meadows without damage. It has good forming effect and high work efficiency.
