Description

Technical Field

[0001] This utility model relates to the technical field of windbreak and sand-fixing vehicles, specifically a windbreak and sand-fixing vehicle. Background Technology

[0002] Windbreak and sand-fixing vehicles are important mechanical auxiliary equipment in sand prevention and control. They can assist in important tasks such as digging and filling ditches for wind-stabilized vegetation and cultivation.

[0003] For example, Chinese Patent Publication No. CN222786315U discloses a windbreak and sand-fixing grass-laying device, including a frame, a ditching mechanism, a grass-sowing mechanism, a seeding mechanism, a grass-pressing mechanism, and a spraying mechanism. The ditching mechanism is located at the front end of the frame and includes an electric push rod, two positioning plates, a connecting rod, and a ditching plow plate. The rear end of the electric push rod is fixed to the frame. The top ends of the two positioning plates are hinged to the free ends of the electric push rod. Each positioning plate has several positioning holes. The top end of the connecting rod is hinged to the front end of the electric push rod, and the middle part of the connecting rod is hinged to the positioning holes on the two positioning plates. The grass-sowing mechanism and the seeding mechanism are both located in the middle of the frame, and the grass-pressing mechanism and the spraying mechanism are both located at the rear end of the frame.

[0004] The aforementioned cited documents demonstrate that the automatic, precise, and uniform laying of straw checkerboard barriers improves the efficiency of straw checkerboard sand barrier laying, reduces labor costs, and has significant practical implications for environmental protection and desertification control.

[0005] Existing windbreak and sand-fixing vehicles require the assembly of different plows for operations such as digging and filling ditches for vegetation cultivation. For example, when digging ditches for vegetation, a plow with a ditching head is needed, or when tilling the roots of weeds in sandy soil before cultivating vegetation, a plow with a spike is needed. However, for different sand-fixing operation scenarios, the sand-fixing vehicle needs to be disassembled and reassembled to replace the original plows. This disassembly and reassembly of the equipment and the inability to carry different plows for changing operations make the operation inconvenient, resulting in the existing windbreak and sand-fixing vehicles being unsuitable for different sand-fixing operation scenarios. Utility Model Content

[0006] The purpose of this utility model is to provide a windproof and sand-fixing vehicle that can quickly adjust and use different plows in different sand-fixing operation scenarios. It is easy to operate and more practical.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a windbreak and sand-fixing vehicle, comprising a sand-fixing vehicle, a plow frame, a plow head, and further comprising:

[0008] The mounting base is fixedly installed at the bottom of the plow frame. A connecting shaft is rotatably installed on one side of the mounting base, and fastening screws are threaded onto both sides of the top of the mounting base.

[0009] The mounting bracket is fixedly installed on the connecting shaft. A connecting plate is fixedly installed on each end of the mounting bracket. A positive and negative screw is rotatably installed on the top of the connecting plate. Two sets of positioning inserts are movably inserted through the ends of the mounting bracket. A positioning block is fixedly installed on the outer end of the positioning insert.

[0010] The plowshares are detachably mounted on their respective connecting plates.

[0011] Preferably, a fixing frame is fixedly installed at the rear end of the sand-fixing vehicle, and the top of the back of the plow frame is slidably installed in the internal guide rail of the fixing frame.

[0012] Preferably, a positioning cylinder is fixedly installed on the top of the fixed frame, and the telescopic end of the positioning cylinder is fixedly connected to the top of the plow frame. Fixing holes are respectively opened on the top of the front of the plow frame and the top of the internal slide rail of the fixed frame, and fastening bolts are fixedly installed in the fixing holes.

[0013] Preferably, the connecting shaft has locating through holes at equal intervals on the circumferential surface near the mounting base, and the fastening screw is threaded through and installed in the locating through holes. A handwheel is fixedly installed on the top of the fastening screw, and a retaining spring is placed between the handwheel and the top of the mounting base.

[0014] Preferably, the top of the connecting plate is provided with a guide groove, the positive and negative lead screws are rotatably installed in the corresponding guide grooves, the end of the positioning insert plate away from the positioning insert block is integrally formed with a sliding plate, the protruding end of the sliding plate slides in the guide groove, and the two sets of corresponding protruding ends of the sliding plate are respectively connected to the positive and negative lead screws by threaded engagement.

[0015] Preferably, the connecting plate has an arc-shaped structure, the positioning block has a triangular cross-section, the plowshare's arc surface fits into the connecting plate's arc surface, and the plowshare's end is provided with a through hole that matches the positioning block, and the positioning block is inserted into the corresponding hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this embodiment of the invention, by rotating the handwheel at the end of the connecting shaft, the mounting bracket on the connecting shaft can rotate circumferentially. This allows the three sets of plowshares arranged in a triangular pattern at the end of the mounting bracket to rotate and adjust their positions. The plowshare at the bottom can be used for sand fixation operations such as plowing roots or filling ditches. By rotating the handwheels at the top of the two sets of fastening screws, the bottom ends of the fastening screws can penetrate into the corresponding positioning through holes. The bottom ends of the fastening screws, equipped with anti-slip rubber sleeves, can prevent vibration and loosen from the positioning through holes, thus securing the connecting shaft after rotation and adjustment.

[0018] This invention allows the sliding plates at the ends of the positive and negative lead screws on either side of the mounting base to move synchronously closer or further apart on the top of the connecting plate by rotating the handwheels on either side. This enables the positioning plates to slide on the corresponding connecting frame ends, and the positioning blocks at the outer ends of the positioning plates can separate from the corresponding plowshare end holes, releasing the positioning. This allows the corresponding plowshare to be removed from the connecting plate, enabling the plowshare to be disassembled and assembled, facilitating the later repair or replacement of damaged plowshares.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a windbreak and sand-fixing vehicle, including a sand-fixing vehicle 100, a plow frame 200, a plow head 500, and further comprising:

[0027] Mounting base 300 is fixedly installed at the bottom of plow frame 200. A connecting shaft 31 is rotatably installed on one side of mounting base 300. Fastening screws 33 are respectively installed on both sides of the top of mounting base 300 by threads.

[0028] Mounting bracket 400 is fixedly mounted on connecting shaft 31. Connecting plate 41 is fixedly mounted on the end of mounting bracket 400. Positive and negative lead screws 42 are rotatably mounted on the top of connecting plate 41. Positioning inserts 43 are movably inserted through the ends of two sets of corresponding mounting brackets 400. Positioning inserts 44 are fixedly mounted on the outer end of positioning inserts 43.

[0029] Each plowshare 500 can be detachably installed on its corresponding connecting plate 41.

[0030] The sand-fixing vehicle 100 has a fixed frame 11 fixedly installed at the rear end. The top of the back of the plow frame 200 is slidably installed in the internal guide rail of the fixed frame 11. The plow frame 200 slides in the front slide rail of the fixed frame 11 through the top convex plate on the back of the plow frame 200. The height of the plow frame 200 from the ground can be adjusted by the telescopic positioning cylinder 12 on the top of the fixed frame 11.

[0031] The fixed frame 11 has a positioning cylinder 12 fixedly installed on its top. The telescopic end of the positioning cylinder 12 is fixedly connected to the top of the plow frame 200. The top of the front of the plow frame 200 and the top of the internal slide rail of the fixed frame 11 are respectively provided with fixing holes, and fastening bolts 13 are fixedly installed in the fixing holes. The fixing holes on the top of the front of the plow frame 200 are fixed by the fastening bolts 13, so that the plow head 500 at the bottom of the plow frame 200 can be adjusted to fit the ground, which is convenient for filling ditches in sandy soil or cultivating and removing weed roots.

[0032] The connecting shaft 31 has locating through holes 32 at equal intervals on the circumferential surface near the mounting base 300. The fastening screw 33 is threaded through and installed in the locating through hole 32. A handwheel is fixedly installed on the top of the fastening screw 33, and a retaining spring 34 is placed between the handwheel and the top of the mounting base 300. By rotating the handwheels at the top of the two sets of fastening screws 33, the bottom end of the fastening screw 33 can pass through the corresponding locating through hole 32. The bottom end of the fastening screw 33 is equipped with an anti-slip rubber sleeve, which can achieve an anti-slip fastening effect with the locating through hole 32. This can fasten and fix the connecting shaft 31 after rotation and adjustment.

[0033] The connecting plate 41 has a guide groove on its top, and the positive and negative lead screws 42 are rotatably installed in the corresponding guide grooves. The positioning insert plate 43 has a slide plate 431 integrally formed at the end away from the positioning insert block 44. The convex end of the slide plate 431 slides in the guide groove. The convex ends of the two sets of corresponding slide plates 431 are respectively connected to the positive and negative lead screws 42 by threaded engagement. The connecting plate 41 has an arc-shaped structure, and the positioning insert block 44 has a triangular cross-section. The arc surface of the plow head 500 fits against the arc surface of the connecting plate 41. The ends of the plow head 500 are respectively provided with inserts that match the positioning insert blocks 44. The positioning insert 44 is inserted into the corresponding insertion hole. By rotating the corresponding positive and negative screws 42, the sliding plates 431 at the ends of the two sets of positioning insert plates 43 can move closer or further away from the top of the connecting plate 41 at the same time. This allows the positioning insert plate 43 to slide on the end of the corresponding connecting frame 400, and the positioning insert 44 at the outer end of the positioning insert plate 43 can be separated from the insertion hole at the end of the corresponding plow head 500 to release the positioning. This allows the corresponding plow head 500 to be removed from the connecting plate 41, realizing the disassembly, repair or replacement of the plow head 500.

[0034] In this embodiment, the sand-fixing vehicle 100 can perform sand-fixing operations such as filling ditches and turning over soil by driving the plow head 500 at the rear end. The plow frame 200 slides on the top convex plate on the back of the plow frame 200 in the front slide rail of the fixed frame 11. The height of the plow frame 200 above the ground can be adjusted by the positioning cylinder 12 at the top of the fixed frame 11. The fixed hole at the top of the front of the plow frame 200 can be fixed by the fastening bolt 13, so that the plow head 500 at the bottom of the plow frame 200 can be adjusted to fit the ground. This is convenient for operations such as filling ditches or cultivating and removing weed roots in sand. The plow frame 200 in this windproof sand-fixing vehicle can be adjusted by the positioning cylinder 12 and the fastening bolt 13, which is a mature technical solution of existing windproof sand-fixing vehicles, and will not be described in detail here.

[0035] In this embodiment, by rotating the handwheel at the end of the connecting shaft 31 on the side of the mounting base 300, the mounting bracket 400 on the connecting shaft 31 can rotate in a circular motion. This allows the three sets of plowshares 500 arranged in a triangular pattern at the end of the mounting bracket 400 to rotate and adjust their positions. The plowshare 500 adjusted to the lowest position can be used for sand fixation operations such as plowing roots or filling ditches. By rotating the handwheels at the top of the two sets of fastening screws 33, the bottom end of the fastening screw 33 can penetrate into the corresponding positioning through hole 32. The bottom end of the fastening screw 33 has an anti-slip rubber sleeve that can prevent vibration and disengagement from the positioning through hole 32. This can securely fix the connecting shaft 31 after rotation and adjustment.

[0036] In this embodiment, by rotating the handwheel at the end of the positive and negative screws 42 on either side of the mounting base 300, the sliding plates 431 at the ends of the two sets of positioning plates 43 can move closer or further away from the top of the connecting plate 41 simultaneously. This allows the positioning plates 43 to slide on the end of the corresponding connecting frame 400, and the positioning blocks 44 at the outer end of the positioning plates 43 can be separated from the insertion holes at the end of the corresponding plowshare 500, releasing the positioning. This allows the corresponding plowshare 500 to be removed from the connecting plate 41, realizing the disassembly and assembly of the plowshare 500, which facilitates the later repair or replacement of damaged plowshare 500.

[0037] Working principle: When the three sets of plow heads 500 in this windbreak and sand-fixing vehicle can be freely switched to adapt to the sand-fixing work scenario, the fastening bolts 13 at the connection between the fixing frame 11 and the plow frame 200 can be removed, and the plow frame 200 can be raised by the positioning cylinder 12, so that the mounting base 300 and the plow head 500 below form a certain gap with the ground, which makes it convenient for the three sets of plow heads 500 to rotate and adjust their positions.

[0038] Then, by rotating the handwheels on the fastening screws 300 on both sides of the top of the mounting base 300, the fastening screws 300 can be separated from the corresponding positioning through holes 32, releasing the positioning of the connecting shaft 31. Then, by rotating the handwheels on the side of the mounting base 300 and the end of the connecting shaft 31, the mounting bracket 400 on the connecting shaft 31 can be rotated in a circular motion. This allows the three sets of plowshares 500 arranged in a triangular pattern at the end of the mounting bracket 400 to be rotated and adjusted. The plowshare 500 at the bottom can be used for sand fixation operations such as plowing roots or filling ditches. By rotating the handwheels at the top of the two sets of fastening screws 33, the bottom end of the fastening screws 33 can penetrate into the corresponding positioning through holes 32. The bottom end of the fastening screws 33 has an anti-slip rubber sleeve that can prevent vibration and disengagement from the positioning through holes 32.

[0039] When disassembling, replacing, or repairing the three sets of plowshares 500 on the mounting frame 400, the handwheels at the ends of the positive and negative screws 42 on either side of the mounting base 300 can be rotated to allow the sliding plates 431 at the ends of the two sets of positioning plates 43 to move synchronously closer or further away from the top of the connecting plate 41. This allows the positioning plates 43 to slide on the corresponding ends of the connecting frame 400, and the positioning blocks 44 at the outer ends of the positioning plates 43 can be separated from the insertion holes at the ends of the corresponding plowshares 500, releasing the positioning. This allows the corresponding plowshares 500 to be removed from the connecting plate 41, enabling the disassembly and assembly of the plowshares 500. This facilitates the later repair or replacement of damaged plowshares 500. Similarly, the anti-slip rubber sleeve on the triangular positioning block 44 can prevent vibration and disengagement from the insertion holes at the ends of the plowshares 500.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
