Description

Technical Field

[0001] This invention belongs to the technical field of wind and sand control equipment, specifically referring to a red willow planting device for wind and sand control in photovoltaic bases. Background Technology

[0002] In the construction and operation of photovoltaic (PV) power plants, wind and sand control is a crucial aspect of ensuring power generation efficiency and equipment safety. PV power plants are often built in deserts and Gobi areas, where wind and sand activity is frequent. Dust storms and sandstorms severely reduce the light transmittance of PV panels, abrade the panel surfaces and supports, increase operation and maintenance costs, and the accumulation of shifting sands can even bury power facilities, threatening the safety of the power plant. Therefore, planting drought-resistant and sand-fixing plants such as tamarisk between PV arrays is a necessary measure to implement biological sand fixation and achieve coordinated development of ecology and engineering.

[0003] However, traditional desert planting methods face severe challenges in the sandy environment of photovoltaic bases. The sand around the tree pits dug manually or mechanically is prone to backflow and collapse, failing to provide stable support. Red willow seedlings, with their root balls, are narrower at the top and wider at the bottom, and are relatively tall with a high center of gravity. When planted in loose sand, they are extremely prone to tilting and falling over under their own weight and wind force. After falling over, the roots do not have sufficient contact with the soil, making it difficult to absorb water and causing them to quickly lose water and die, severely affecting the effectiveness of sand-fixing forest construction.

[0004] Currently, manual planting relies on repeated soil covering and trampling, which is inefficient and yields uneven results. Most existing planting machinery is designed for ordinary soil, and its seedling mechanism lacks an effective immediate seedling stabilization function in sandy soil. It cannot directionally compact the sandy soil around the roots after planting, nor can it simultaneously achieve precise uprighting and continuous support for the seedlings, resulting in poor uprightness and a high lodging rate after planting.

[0005] Therefore, there is an urgent need to develop an automated planting device that can specifically address the loose characteristics of sandy land and effectively prevent the lodging of high-center-of-gravity seedlings such as red willow, in order to meet the needs of large-scale, high-efficiency, and high-survival-rate wind and sand control operations in photovoltaic bases. Summary of the Invention

[0006] In response to the above situation, and to overcome the shortcomings of current desertification control processes, such as loose sandy soil and high center of gravity of tamarisk seedlings leading to easy tipping over, insecure fixation, and low survival rate after planting, this invention provides a tamarisk planting device for wind and sand control in photovoltaic bases. This device effectively solves the problem that existing planting equipment cannot simultaneously and accurately straighten seedlings, effectively compact the soil around the roots, and reliably recycle the planting base in soft sandy soil, resulting in low planting efficiency and low survival rate of tamarisk.

[0007] The technical solution adopted by this invention is as follows: This invention provides a red willow planting device for wind and sand control in photovoltaic bases, including a trailer for desert planting. The trailer is loaded with multiple sets of wheels to prevent the trailer from sinking into the sand due to its weight when moving in the desert. The top wall of the trailer is equipped with a tray for placing red willow seedlings. The top wall of the trailer is equipped with a downwardly extending cylinder. The cylinder is equipped with a connecting plate. The connecting plate is equipped with an annular limiting plate. The annular limiting plate is equipped with a working box. The working box is equipped with a seedling fixing device. The seedling fixing device is equipped with a root sand compaction device. The root sand compaction device is equipped with a one-way limiting structure. The one-way limiting structure is equipped with a seedling combination base.

[0008] Furthermore, the seedling fixing device includes a support plate, a cylinder sliding connecting plate, cylinder a, a seedling fixing clamp, a fan-shaped connecting plate, a cylinder a groove, and a connecting plate groove. The support plate is fixedly mounted on the work box, the connecting plate groove is mounted on the support plate, the cylinder sliding connecting plate slides along the connecting plate groove, cylinder a is fixedly mounted on the cylinder sliding connecting plate, the fan-shaped connecting plate is fixedly connected to cylinder a, the cylinder a groove is mounted on the support plate, cylinder a slides along the cylinder a groove, and the fan-shaped connecting plate is fixedly connected to the seedling fixing clamp. By pushing the fan-shaped connecting plate, the seedling fixing clamp clamps the red willow seedling. The cylinder a groove allows cylinder a to slide vertically along the direction of the support plate after extension, thus sending the seedling into the soil.

[0009] Furthermore, the root sand compaction device includes a sand compaction plate, a central connecting plate, a plate-to-plate connecting bracket A, a plate-to-plate connecting bracket B, a ball screw, a screw groove, a nut, a cylinder b, a cylinder block, and a block groove. The sand compaction plate and the central connecting plate are both fixedly installed on the seedling fixing clamp. The two ends of the plate-to-plate connecting bracket A are respectively connected to the central connecting plate and the fan-shaped connecting plate. The two ends of the plate-to-plate connecting bracket B are respectively fixedly connected to the sand compaction plate and the central connecting plate. The ball screw is engaged and rotated in the ball screw groove on the support plate. The nut is threadedly connected to the ball screw and is engaged and slidable in the ball screw groove. The cylinder b is fixedly mounted on the nut. The cylinder block is fixedly mounted on the cylinder b. The block groove is set on the sector-shaped connecting plate. The cylinder block is engaged and slidable in the block groove. When the cylinder a extends, the cylinder block engages and slides in the block groove without affecting the pressing action of the cylinder b on the sector-shaped connecting plate.

[0010] Furthermore, the one-way limiting structure includes a ratchet, a one-way locking block, an outer limiting ring, an inner rotating ring, and a limiting protrusion. The outer limiting ring is fixedly installed on the work box, the inner rotating ring engages and rotates within the outer limiting ring, the limiting protrusion is fixedly disposed on the inner wall of the inner rotating ring, the one-way locking block engages and rotates in the gap between two adjacent sets of limiting protrusions, a torsion spring is provided between the one-way locking block and the inner rotating ring, and the ratchet engages and rotates at the center of the inner rotating ring.

[0011] Furthermore, the unidirectional limiting structure also includes a transmission gear, a transmission rack, a cylinder c, a gear transverse support, a gear locking block, a gear moving slot, and an internal ring connecting bracket. The cylinder c is fixedly installed on the outer wall of the work box, the gear transverse support is fixedly connected to the cylinder c, the transmission gear is fixedly connected to the gear transverse support, the transmission rack meshes with the transmission gear and slides on the inner wall of the work box, the gear locking block is fixedly installed on the transmission gear, the gear moving slot is located at the center of the ratchet, the internal ring connecting bracket is fixedly installed at the center of the internal rotating ring, the gear locking block slides in the gear moving slot, the internal ring connecting bracket rotates on the inner wall of the work box, and a torsion spring is provided at the connection between the work box and the internal ring connecting bracket.

[0012] Furthermore, the transmission rack is provided with a fixedly connected bracket a, the middle connecting plate is provided with a horizontal sliding groove for bracket a, and the support plate is provided with a vertical sliding groove for bracket a. The bracket a is engaged in the horizontal sliding groove of bracket a. As the sand compaction plate descends, bracket a moves vertically downward, pushing the transmission rack to move, causing the transmission gear to gain rotational kinetic energy. The gear block rotates with the transmission gear, thereby causing the ratchet to rotate. When the ratchet rotates within the built-in rotating ring, the one-way block is squeezed by the ratchet and hidden in the gap between two adjacent sets of limiting protrusions. The built-in rotating ring will not be displaced. When the transmission rack moves upward, the ratchet reverses, the ratchet squeezes the one-way block, and the one-way block squeezes the limiting protrusion, causing the built-in rotating ring to rotate. The built-in rotating ring drives the built-in ring connecting bracket to rotate.

[0013] Furthermore, the seedling combination base includes a seedling root support plate, a support plate bracket, and an external protruding rib. The support plate bracket is fixedly connected to the internal ring connecting bracket. The seedling root support plate is fixedly set on the bottom wall of the support plate bracket, and the external protruding rib is set on the outer wall of the seedling root support plate. Multiple sets of seedling root support plates can form a cone shape, which can better provide support and protection for the seedlings. At the same time, the connection between the external protruding rib and the seedling root support plate is set with a rounded corner to reduce the resistance between the seedling root support plate and the sand when it is turned out of the sand. Therefore, the width of the seedling root support plate can be designed to be smaller.

[0014] This solution provides a red willow planting device for wind and sand control in photovoltaic power bases, which has the following beneficial effects: (1) Through the synergistic effect of the seedling fixing device and the seedling combination base, the problem of red willow seedlings being prone to lodging in soft sandy soil is effectively solved. The seedling fixing clamp can reliably hold the main trunk of the red willow seedling, while multiple seedling root support plates are combined into a cone-shaped structure, which lifts and protects the root ball of the seedling from the bottom during the planting process. This top-to-bottom synergistic fixing method ensures that the seedling remains upright throughout the entire process from planting in sandy soil to completing the fixing, which significantly improves the verticality and stability of the planting. (2) This device integrates a high-efficiency root sand compaction device, which can automatically and forcefully compact the sand around the seedling roots. By driving the sand compaction plate down through the cylinder, the loose sand around the planting hole can be effectively compressed, so that the seedling roots are in close contact with the sand. This process greatly enhances the initial stability of the seedlings in the sandy land, effectively prevents the roots from being exposed due to wind erosion or sand flow, and provides a solid foundation for the survival of the seedlings. (3) The linkage and recycling mechanism of the one-way limiting structure and the seedling combination base designed in this application realizes the smooth detachment and reuse of the base after planting. During the process of lifting the base after the sand compaction plate compacts the soil, the built-in rotating ring is driven to rotate by components such as ratchet and one-way locking block, thereby driving the base plate of the seedling root to flip outward and separate from the seedling root and sand. This design avoids damage to the root caused by the base being forcibly pulled up and ensures that the device can be quickly reset for continuous operation, which greatly improves the planting efficiency.

[0025] The transmission rack 30 is provided with a bracket a36, the middle connecting plate 15 is provided with a horizontal slide groove 37 for bracket a, and the support plate 7 is provided with a vertical slide groove 38 for bracket a.

[0026] The seedling combination base 6 includes a seedling root support plate 39, a support plate bracket 40, and an external protrusion 41. The support plate bracket 40 is fixedly connected to the internal ring connecting bracket 35. The seedling root support plate 39 is fixedly set on the bottom wall of the support plate bracket 40, and the external protrusion 41 is set on the outer wall of the seedling root support plate 39.

[0027] In practical use, the equipment is installed on a trailer, which is towed by a sand-tracked vehicle. The red willow seedlings are placed on a tray, and the planter sits on the trailer and sends the red willow seedlings in the tray between the seedling fixing clamps 10. Since the roots of the red willow seedlings are covered with soil, the seedlings are narrow at the top and wide at the bottom. In order to ensure that the red willows can grow vertically after planting, the seedlings need to be limited to prevent them from tipping over. The cylinder a9 is extended, and the fan-shaped connecting plate 11 slides horizontally under the action of the cylinder a9. The seedling fixing clamps 10 clamp and fix the main trunk of the red willow, and the roots of the red willow are supported by the seedling root support plate 39. When cylinder a9 extends, cylinder block 22 on cylinder b21 engages and slides within block groove 23 on sector connecting plate 11. Using the cylinder installed on the trailer, the annular limiting plate 1 is pressed down, and the seedling root support plate 39 is buried in the sand. The conical structure formed by the seedling root support plate 39 helps to break through the surface layer of the sand. After the seedling root support plate 39 puts the roots of the red willow into the sand, it is necessary to press down the area where the red willow roots are located to make the surrounding sand and red willow relatively stable and prevent the roots of the red willow from being exposed due to wind and sand. Then, the ball screw 18 rotates, the nut 20 slides in the screw groove 19, the cylinder b21 moves downward, and the sand pressing plate 14 moves to the surface of the sandy soil. Cylinder b21 extends and presses the fan-shaped connecting plate 11, causing the sand pressing plate 14 to move downward. The cylinder sliding connecting plate 8 slides in the connecting plate groove 13, and cylinder a9 slides along the cylinder a groove 12. During the process of the inter-plate connecting bracket A16 sliding down with the sand pressing plate 14, the engagement relationship between the supported plate 7 and the inter-plate connecting bracket A16 ensures the stability of the movement direction of the inter-plate connecting bracket A16. The sand compaction plate 14 presses down to fix the sand in the area where the red willow roots are located, ensuring the relative stability of the red willow seedlings in this area. When the sand compaction plate 14 is pressed down, the gear transverse support 32 descends along with the middle connecting plate 15, the transmission rack 30 descends, the transmission gear 29 rotates, and the ratchet 24 rotates along with the rotation of the transmission gear 29. The ratchet 24 rotates when the transmission rack 30 descends, and the ratchet 24 squeezes the one-way block 25. However, the one-way block 25 is hidden in the hidden groove between the two sets of limiting protrusions 28 in the built-in rotating ring 27. The ratchet 24 cannot drive the built-in rotating ring 27 to produce displacement. Therefore, in this process, the sand compaction plate 14 only has the function of pressing the sand at the root of the red willow. Then cylinder b21 contracts, sand pressing plate 14 moves up, ratchet 24 rotates in a different direction than when transmission rack 30 descends, ratchet 24 presses one-way block 25, one-way block 25 presses limit protrusion 28, causing the built-in rotating ring 27 to rotate, the built-in rotating ring 27 drives the built-in ring connecting bracket 35 to rotate, the tray bracket 40 is raised, and the seedling root tray 39 is separated from the root of the red willow by a certain distance; Continuing the above operations, the seedling root support plate 39 gradually detaches from the sand, and the soil around the roots of the red willow is gradually pressed and fixed. When the seedling root support plate 39 is reset, the cylinder c31 extends, the gear transverse support 32 moves transversely, the transmission gear 29 moves horizontally, the transmission gear 29 slides with the ratchet 24, the transmission rack 30 is misaligned with the transmission gear 29, the gear block 33 disengages from the gear moving slot 34, but part of the support on the transmission gear 29 where the gear block 33 is located is still hidden in the gear moving slot 34, the potential energy of the torsion spring connected to the built-in ring connecting support 35 is released, the built-in rotating ring 27 rotates, and the seedling root support plate 39 returns to its initial state; The trailer is then moved to the next planting area, and the above operations are performed.

[0029] The present invention and its embodiments have been described above.
