Description

Technical Field

[0001] This utility model relates to the field of sand control technology, and in particular to a device for fixing sand and covering forestry sandy land with grass. Background Technology

[0002] Sand grains in sandy areas are relatively loose and easily blown away by the wind, forming shifting dunes. Mulching can block the direct impact of wind on the sand, reduce wind speed, and decrease the amount of sand erosion. A common method for mulching is manual insertion: the mulch is laid flat on the sand surface, and a tool is used to apply pressure from the center, causing the mulch to bend and penetrate the sand to a certain depth before the tool is removed.

[0003] However, manually inserting mulch requires the use of tools such as shovels and spades to push the straw or other covering material into the slope or sandy ground. This process is physically demanding, especially in large-scale sandy land management, where the labor intensity is extremely high, easily causing worker fatigue and reducing work efficiency. Compared with mechanized equipment, manual insertion is relatively slow and it is difficult to complete the mulch fixing work over a large area in a short time, which cannot meet the needs of large-scale sandy land management and limits the progress of sandy land management. Utility Model Content

[0007] Preferably, mounting plates are bolted to both sides of the notch on the surface of the frame, and rotating shafts distributed parallel to the length direction of the notch are rotatably connected to the surface of the mounting plates. Winding wheels are installed on both ends of the rotating shafts near the adjacent long side of the lifting plate.

[0008] Preferably, the traction line wound on the surface of the reel passes through the top edge of the frame and is connected to the long side of the upper surface of the lifting plate on the same side.

[0009] Preferably, a gear shaft is fixedly installed through the swing fulcrum of the swing frame. The gear shaft is horizontally arranged and both ends of the gear shaft are rotatably connected to the frame. An electric push rod for driving the pressure bar to move and whose telescopic end is inserted into the inner wall of the swing frame is fixedly installed on the swing frame.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, a forestry sandy land covering and sand-fixing device includes a frame 1. Two tracked wheels 2 are mounted on the bottom of the frame 1, allowing for easy operation and movement of the frame 1 on the sandy surface. A lifting plate 7, sliding longitudinally and horizontally, is slidably mounted on the surface of the frame 1. Mounting plates 3 are bolted to both sides of a notch 11 on the surface of the frame 1. Rotating shafts 4, parallel to the length of the notch 11, are rotatably connected to the surface of the mounting plates 3. Winding wheels 5 are mounted on the surfaces of the rotating shafts 4 near the adjacent long sides of the lifting plate 7. The traction line wound on the surface of the winding wheels 5 passes through the top edge of the frame 1 and connects to the long side of the upper surface of the lifting plate 7 on the same side. One of the rotating shafts 4 is driven by a motor, and both rotating shafts 4 are in the same direction. Synchronous pulleys 6 are fixedly installed at one end, and synchronous belts are provided on the surfaces of the two synchronous pulleys 6. The purpose of setting the rotating shaft 4 and the synchronous pulleys 6 is to realize the smooth lifting and lowering of the lifting plate 7. Specifically, the synchronous pulleys 6 and the synchronous belts can be replaced with sprockets and chains. In actual use, a stepper motor is set on one of the mounting bases to drive the rotating shaft 4 to rotate, while the rotating shaft 4 on the other mounting base rotates simultaneously due to the synchronous pulleys 6 and the synchronous belts. By using the two rotating shafts 4 to rotate at the same speed, the four winding wheels 5 used in this solution can be rotated simultaneously, so as to release or rewind the traction line wound on the surface of the winding wheel 5. When the traction line is released, the lifting plate 7 can be lowered; conversely, when the traction line is wound up, the lifting plate 7 can be raised.

[0023] A notch 11 is provided at the center of the side of the lifting plate 7 facing away from the handlebar of the frame 1. Clamping plates 13 are hinged to both sides of the notch 11 on the upper surface of the lifting plate 7. The required mulch is laid flat on the surface of the lifting plate 7, and the ends of the mulch are held in place by the clamping plates 13. The swinging edge of the clamping plates 13 is used to hold down the ends of the mulch, and a worm gear 18 is fixedly installed at one hinge point of the clamping plates 13 through the lifting plate 7. A worm 17 is rotatably connected to the surface of the lifting plate 7 and meshes with the worm gear 18. The two worms 17 are coaxially distributed, and the upper surface of the lifting plate 7 is positioned at a misaligned location relative to the notch 11. A dual-axis motor 12 is fixedly installed to drive the rotation of two worm gears 17. The dual-axis motor 12 is located on the lifting plate 7 near the handrail of the frame 1. When the clamping plate 13 is needed, the two main shafts of the dual-axis motor 12 are connected to the two worm gears 17 respectively. Therefore, by using the dual-axis motor 12 to drive the two worm gears 17 to rotate at the same time, the worm wheel 18 that is meshed with the corresponding worm gear 18 can drive the corresponding clamping plate 13 to swing. When the clamping plate 13 swings upward, it is convenient for personnel to place the mulch and press the mulch into the sand. When the clamping plate 13 swings downward, it is convenient to press and fix the mulch laid on the lifting plate 7.

[0024] A swing frame 8 is hinged to the frame 1. The swing frame 8 and the notch 11 are located on the central axis of the frame 1, and a pressure strip 10 for passing through the notch 11 is inserted into the swing frame 8. A gear shaft 14 is fixedly installed through the swing fulcrum of the swing frame 8. The gear shaft 14 is horizontally set and both ends of the gear shaft 14 are rotatably connected to the frame 1. An electric push rod 9 for driving the pressure strip 10 to move is fixedly installed on the swing frame 8, and its telescopic end is inserted into the inner wall of the swing frame 8. A rack 15 is inserted into the frame 1 and meshed with the gear end of the gear shaft 14. An electric telescopic rod 16 is provided between the rack 15 and the frame 1. The electric telescopic rod 16 and the rack 15 are staggered with the lifting plate 7. Figure 1 As shown, when the swing frame 8 is in a vertical state, it is misaligned with the lifting plate 7 and will not affect the lifting of the lifting plate 7. When the lifting plate 7 descends to the lowest point, that is, below the swing frame 8, the electric telescopic rod 16 extends to push the rack 15 down, which enables the meshing gear shaft 14 to drive the swing frame 8 to rotate to a horizontal state. The swing frame 8 is located above the notch 11 on the surface of the lifting plate 7. When the clamp 13 releases the pressure on the mulch, the electric push rod 9 extends to push the pressure strip 10 down and directly act on the mulch surface. As the pressure strip 10 continues to descend, the mulch can be automatically bent and inserted into the sand from the notch 11, thus achieving automatic mulch fixation.

[0025] The method of using this utility model is as follows:

[0026] The operator pushes the device through the handle of the frame 1 and uses the track wheels 2 at the bottom to move flexibly on the sandy surface, adjusting the device to the target area to be covered with grass.

[0027] The straw to be used is laid flat on the upper surface of the lifting plate 7, and the two side clamps 13 are lowered until the clamps 13 swing and press the two ends of the straw, thus initially fixing the straw on the lifting plate 7. The two rotating shafts 4 rotate synchronously at the same speed, driving the four winding wheels 5 on the surface to release the traction lines synchronously; the traction lines drive the lifting plate 7 to slide down longitudinally along the frame 1 until the lifting plate 7 reaches the lowest point.

[0028] The electric telescopic rod 16 extends and pushes the rack 15 down, causing the gear shaft 14 to rotate, which in turn causes the swing frame 8, which was originally in a vertical state, to rotate to a horizontal state. The pressure strip 10 inside the swing frame 8 is aligned with the notch 11 of the lifting plate 7, driving the worm gear 17 to rotate in the opposite direction. Through the worm wheel 18, it drives the two side clamps 13 to swing up, releasing the pressure on both ends of the straw cover.

[0029] The electric push rod 9 extends and pushes the pressure strip 10 down along the inner wall of the swing frame 8. The pressure strip 10 acts directly on the mulch surface. As the pressure strip 10 continues to descend, it forces the mulch to automatically bend along the notch 11 and gradually insert it into the sand from the notch 11, thus completing the automatic fixing of the mulch.

[0030] The wiring diagrams for the track wheel 2, electric push rod 9, stepper motor, dual-axis motor 12, and electric telescopic rod 16 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the track wheel 2, electric push rod 9, stepper motor, dual-axis motor 12, and electric telescopic rod 16 will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
