Description

Technical Field

[0001] This utility model relates to the field of artificial turf technology, specifically to a cutting and repair device for artificial turf. Background Technology

[0002] Lawns, as a common landscaping feature, are widely used in sports fields, soil and water conservation areas, parks, and residential communities, serving to beautify the environment and provide spaces for rest and recreation. However, lawns are prone to developing localized necrosis after natural growth or prolonged trampling, exposing the underlying soil and affecting their overall aesthetics; timely repair is necessary.

[0003] In the prior art, for example, the utility model patent with authorization announcement number CN222897828U discloses a cutting and repair device for artificial turf. This device uses a frame to extract necrotic turf pieces and a top plate to remove the turf pieces, solving the problems of cumbersome operation and low survival rate of traditional shovels. However, this device still has the following shortcomings: the frame size is fixed, which cannot adapt to necrotic areas of different sizes, and multiple sizes of devices are required, increasing the cost of use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cutting and repair device for artificial turf, which solves the problem that existing artificial turf repair devices cannot adapt to necrotic areas of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting and repairing device for artificial turf, comprising an operating rod, a handle fixedly connected to the upper end of the operating rod, a top plate fixedly connected to the lower end of the operating rod, a frame fixedly connected to the lower end of the top plate via a support column, an adjustable cutting plate assembly provided on the frame, the cutting plate assembly comprising multiple cutting plates, and an adjustment mechanism for driving the cutting plates to move to adjust the cutting range, the adjustment mechanism comprising a fixed block fixedly connected to the middle position of one side of the frame, a threaded rod passing through the middle of the fixed block, a linkage block rotatably connected to one end of the threaded rod near the center of the frame, sliding rods symmetrically fixedly connected to both ends of the linkage block, a moving block slidably connected to the sliding rod, a moving plate fixedly connected to the lower end of the moving block, a slider provided at the lower end of the moving plate and slidingly cooperating with a guide rail, the guide rail being symmetrically arranged on the upper surface of the frame, and one end of the moving plate being fixedly connected to the cutting plate.

[0006] By adopting the above structural design, and setting up an adjustable cutting plate assembly consisting of multiple cutting plates and adjustment mechanisms, the user can drive the linkage block to move by rotating the threaded rod, and then drive the moving plate and the cutting plate connected to it to slide on the guide rail through the sliding rod and the moving block, thereby flexibly adjusting the area of ​​the cutting area enclosed by the four cutting plates. This effectively solves the problem of fixed frame size in the prior art, which cannot adapt to necrotic areas of different sizes, and improves the adaptability of the device to lawns with different damaged areas.

[0007] Preferably, the cross-section of the cutting plate is L-shaped, the number of cutting plates is four, and the cutting plates are symmetrically distributed along the inner side of the frame.

[0008] By adopting the above structural design, the cross-section of the cutting board is set in an L-shape and symmetrically distributed along the inner side of the frame. The L-shaped structure enhances the structural strength of the cutting board itself, making it less prone to deformation when cutting into turf. Furthermore, its vertical edges effectively contain soil, while the horizontal edges facilitate connection with components such as the movable board. The symmetrical arrangement of the four cutting boards ensures that the cutting range always forms a regular rectangle during adjustment, resulting in a standard repair block shape that easily matches the regular rectangular area to be repaired, improving the aesthetics and fit of the repaired area.

[0009] Preferably, the threaded rod is provided with an external thread, and the linkage block is provided with an internal thread adapted to the external thread, and the threaded rod and the linkage block are threadedly engaged.

[0010] By employing the above structural design and using a threaded rod and a linkage block with a threaded connection, precise and linear control of the cutting board's movement is achieved. This threaded transmission method offers smooth and reliable adjustment, and features a self-locking function. It can be securely locked after adjustment to the desired position, preventing accidental displacement of the cutting board during turf cutting and ensuring the accuracy of the cutting dimensions and the safety of the operation.

[0011] Preferably, the frame is further provided with a connecting plate, which is located between two adjacent cutting plates and is parallel to the cutting plates. The upper end of the connecting plate is slidably connected to the side wall of the cutting plate.

[0012] The above structural design incorporates a connecting plate that moves in tandem with the cutting plates, slidably connected to the sidewalls of the cutting plates. When the cutting plates move to expand the cutting range, the connecting plate extends to fill gaps created on the sides of the frame due to the plate movement, ensuring the device remains sleek and sealed. This effectively prevents lateral soil leakage during cutting and extracting turf pieces, ensuring neat edges and intact soil layers, thereby improving the survival rate of subsequent transplanting and repair.

[0013] Preferably, the operating lever is further provided with a pressing lever, which is arranged perpendicularly to the operating lever.

[0014] The above structural design, with a foot pedal perpendicular to the control lever, provides the operator with an additional point of leverage. When pressing the frame into the turf, the operator can step on the foot pedal, making it easier and more efficient to cut the cutting board into the turf, reducing the operator's workload. This advantage is particularly noticeable when dealing with hard soil or areas with dense grass roots.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By incorporating an adjustable cutting plate assembly consisting of multiple cutting plates and adjustment mechanisms, users can drive a linkage block to move by rotating a threaded rod. This, in turn, causes a sliding plate and its connected cutting plates to slide along a guide rail via a sliding rod and a moving block, allowing for flexible adjustment of the cutting area enclosed by the four cutting plates. This effectively solves the problem of fixed frame dimensions in existing technologies, which cannot adapt to different areas of damaged turf, thus improving the device's adaptability to different damaged turf areas. A connecting plate, which moves in tandem with the cutting plates, is installed between adjacent cutting plates and slides along the side wall of the cutting plates. When the cutting plates move to expand the cutting range, the connecting plate extends to fill the gaps created on the side of the frame due to the cutting plate movement, ensuring the device's side sealing. This effectively prevents lateral soil leakage during cutting and extracting turf pieces, ensuring neat edges and intact soil in the extracted turf pieces, thereby improving the survival rate of subsequent transplanting and repair.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a cutting and repair device for artificial turf, including an operating rod 2. The upper end of the operating rod 2 is fixedly connected to a handle 3 for the operator to hold, and the lower end is fixedly connected to a horizontally positioned top plate 1. The lower surface of the top plate 1 is fixedly connected to a frame 6 via support columns 5 at the four corners, maintaining a certain distance between the frame 6 and the top plate 1 to allow space for operation. The frame 6 is a rectangular frame and serves as the basic support structure of this device. An adjustable cutting plate assembly is provided on the frame 6. The cutting plate assembly includes four L-shaped cutting plates 7, located at the four corners inside the frame 6 and symmetrically distributed along the inner side of the frame 6. Each cutting plate 7 has a sharp blade at its bottom for cutting turf. An adjustment mechanism is used to drive the four cutting plates 7 to move synchronously to adjust the size of the rectangular cutting area they enclose. The adjustment mechanism includes a fixing block 14 fixedly connected to the middle position of one side of the frame 6, and a threaded rod 13 passes through the fixing block 14 and is threadedly connected to it. One end of the threaded rod 13 extends to the outside of the frame 6 and can be equipped with a knob, while the other end extends towards the center of the frame 6. A linkage block 15 is rotatably connected to the end of the threaded rod 13 near the center of the frame 6. Specifically, a blind hole can be opened in the linkage block 15, and a bearing can be installed inside the hole. The end of the threaded rod 13 is inserted into the inner ring of the bearing, so that the threaded rod 13 rotates while the linkage block 15 does not rotate, but can only move along the axial direction of the threaded rod 13. Sliding rods 9 are symmetrically fixedly connected to both ends of the linkage block 15, and the axial direction of the sliding rods 9 is perpendicular to the axial direction of the threaded rod 13. Each sliding rod 9 is fitted with a sliding block 11 that can slide along it, and a moving plate 10 is fixedly connected to the lower end of each moving block 11. A slider is provided at the lower end of the moving plate 10 and slides in cooperation with a guide rail 12 fixedly installed on the upper surface of the frame 6. Two guide rails 12 are provided, symmetrically arranged on one side of the upper surface of the frame 6, and one end of the moving plate 10 is fixedly connected to the cutting plate 7.

[0023] The cross-section of the cutting plate 7 is L-shaped, and there are four cutting plates 7, which are symmetrically distributed along the inner side of the frame 6.

[0024] The threaded rod 13 is provided with an external thread, and the linkage block 15 is provided with an internal thread adapted to the external thread. The threaded rod 13 and the linkage block 15 are threadedly engaged. Therefore, when the threaded rod 13 is rotated by the knob, the linkage block 15 will move inward or outward along the axial direction of the threaded rod 13, thereby driving the two sliding rods 9 to move synchronously. The sliding rods 9 then push the two moving blocks 11 and the moving plate 10 to slide along the guide rail 12, ultimately realizing the synchronous approach or distance of the four cutting plates 7, thereby steplessly adjusting the size of the cutting area.

[0025] To maintain the sealing of the device's sides and prevent soil leakage after the cutting plate 7 moves, a connecting plate 8 is also provided inside the frame 6. The connecting plate 8 is located between two adjacent cutting plates 7 and is parallel to them. The upper end of the connecting plate 8 is slidably connected to a groove provided on the cutting plate 7 via a snap-fit. When the cutting plate 7 moves, the connecting plate 8 moves accordingly, always filling the gap between the cutting plate 7 and the side of the frame 6. The lower end of each connecting plate 8 is a sharp cutting edge.

[0026] In addition, a foot pedal 4 perpendicular to the operating lever 2 is fixedly connected to the operating lever 2. This foot pedal 4 allows the operator to easily step on it with their foot, thus making it easier to cut the cutting board 7 into the turf to be repaired.

[0027] Working principle:

[0028] First, based on the area of ​​the necrotic turf to be repaired, rotate the threaded rod 13 to adjust the position of the four cutting plates 7 so that the size of the rectangle they form matches the repair area. Then, align the frame 6 with the area to be repaired, press down on the foot pedal 4, and use your body weight to push the entire device downwards, causing the cutting edges of the cutting plates 7 to cut into the turf, completing the cut. After descending, lift the handle 3 upwards to remove the neatly cut turf piece. Subsequently, use the same device to cut a turf piece of the same size from a spare piece of good turf, place it in the area to be repaired, and tamp it down with your foot to complete the repair.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
