Description

Technical Field

[0001] This invention relates to the field of sandy land afforestation technology, specifically a reusable biological protective tray for sandy land afforestation. Background Technology

[0002] Afforestation in sandy areas is of great significance for improving the ecological environment, preventing wind and sand erosion, conserving water and soil, and increasing the productivity of sandy areas. Through afforestation, vegetation cover in sandy areas can be increased, wind erosion and sand burial can be reduced, thereby improving soil conditions, increasing soil fertility, and providing a better environment for crop growth.

[0003] In the field of desert afforestation or sandy land afforestation, biological protective trays usually refer to a device used to improve the survival rate of saplings. These biological protective trays are usually disc-shaped, with a certain thickness and diameter, a round hole in the middle, and a notch connecting to the outside. The main function of biological protective trays is to resist the rapid evaporation of soil moisture caused by continuous wind, while increasing the soil temperature of the root zone, thereby helping the growth and survival of saplings.

[0004] Currently, commercially available biological support trays for afforestation in sandy areas have a simple structure that makes them prone to being discarded after use. Furthermore, these trays only provide protection for the plant roots, failing to integrate simultaneous plant support and drip irrigation. Therefore, an improved device is needed to address these issues. Summary of the Invention

[0005] To address the problems in the existing technology, the present invention provides a reusable biological protective mat for afforestation in sandy areas.

[0006] The technical solution adopted by this invention to solve its technical problem is: a reusable biological protective tray for afforestation in sandy areas, comprising an accumulation mechanism, a connecting pipe fixedly installed at the top of the accumulation mechanism, and supporting bases symmetrically fixedly installed at the bottom of the accumulation mechanism. The accumulation mechanism includes an alignment device and a protective component. The alignment device is symmetrically fixedly installed at the top of the protective component. The alignment device includes a connecting top plate, a first rack, a first gear, an extension bracket, a top support plate, a hexagonal rod, a supporting vertical plate, a return spring, and a limiting rod. The extension bracket is fixedly installed at the top of the side end of the top support plate. The first gear is rotatably installed at the top of the extension bracket. The hexagonal rod is slidably inserted into the inner end of the top support plate away from the extension bracket. The connecting top plate is fixedly installed at the top of the hexagonal rod. The return spring is fixedly installed between the top support plate and the connecting top plate. The first rack is fixedly installed on the side end of the connecting top plate near the first gear. The top support plate is fixedly installed on the top of the supporting vertical plate. The limiting rod is fixedly installed on the side end of the supporting vertical plate away from the hexagonal rod.

[0007] Specifically, the protective component includes a blocking device, a synchronizing device, and a supporting device. The blocking device is slidably inserted into the top of the synchronizing device, and the synchronizing device is fixedly installed on the top of the supporting device.

[0008] Specifically, the sealing device includes an extension side frame, a sealing plug, a round rod, an L-shaped bracket, a second rack, an arc-shaped top plate, and a third rack. The extension side frame is symmetrically fixedly installed on the outer ring of the arc-shaped top plate. The third rack is fixedly installed on the end of the extension side frame away from the arc-shaped top plate. The round rod is fixedly installed on the bottom end of the arc-shaped top plate, and the round rod is distributed in a ring. The sealing plug is fixedly installed on the bottom end of the round rod. The L-shaped bracket is fixedly installed on both ends of the arc-shaped top plate away from the third rack. The second rack is fixedly installed on the top end of the L-shaped bracket away from the arc-shaped top plate.

[0009] Specifically, the synchronization device includes a support arm, a second gear, a support top seat, a round hole, a cover plate, a bolt, and a push plate. The bolt is rotatably mounted on the top of the cover plate, the round hole is opened on the top of the cover plate near the bolt, the support top seat is symmetrically fixedly mounted on the top of the cover plate, the second gear is rotatably mounted on the top of both sides of the support top seat, the support arm is fixedly mounted between the two second gears, and the push plate is fixedly mounted on the top of the support arm away from the support top seat.

[0010] Specifically, the support device includes a drip tube and a water storage chamber. The drip tube is fixedly installed at the bottom end of the water storage chamber and is arranged in a ring.

[0011] Specifically, the supporting vertical plate is fixedly installed at both ends of the top of the cover plate, the cover plate is fixedly installed at the top of the water storage cavity, the third rack meshes with the second gear, the connecting pipe is fixedly connected to the round hole, the round rod is slidably inserted into the inside of the cover plate, the arc-shaped top plate is threaded onto the outer ring of the bolt, the second rack meshes with the first gear away from the outer ring of the first rack, and the supporting base is symmetrically fixedly installed at the bottom of the water storage cavity.

[0012] Specifically, the limiting rod has a hexagonal hole inside, the supporting vertical plate has a slot inside near the hexagonal rod that matches the limiting rod, the arc-shaped top plate has a threaded hole inside near the side end of the extension side frame, the sealing plug is vertically aligned with the top of the drip tube, the water storage cavity is hollow inside, and the water storage cavity is interconnected with the drip tube.

[0013] Specifically, a plastic gasket is fixedly installed on the surface of the push plate, a round hole adapted to the round rod is opened on the top of the cover plate, and a hexagonal hole adapted to the hexagonal rod is opened inside the top support plate.

[0014] Specifically, the extended side frame is 3 cm longer in radius than the cover plate. The bottom of the first rack away from the connecting top plate meshes with the first gear, and the top of the second rack away from the arc-shaped top plate meshes with the outer ring of the first gear away from the side of the first rack.

[0015] Specifically, the support base includes a screw, an extension plate, and a plug rod. The extension plate is fixedly installed on the side of the support base away from the accumulation mechanism. The screw is threaded into the inside of the extension plate, and the plug rod is fixedly installed at the center of the bottom end of the screw.

[0016] The beneficial effects of this invention are:

[0017] First, this invention allows the bolts to rotate, causing the arc-shaped top plate to move upwards. This enables the extended side frame to drive the third rack through the second gear, thereby rotating the support arm upwards until the push plate moves closer to the center of the cover plate. This supports the plant located between the two water storage chambers, preventing the plant from tilting when exposed to wind and sand. Furthermore, as the arc-shaped top plate moves upwards, it engages the second rack with the first gear, allowing the first rack to drive the hexagonal rod downwards. This allows the hexagonal rod to be inserted into the interior of another limiting rod, positioning and merging the two water storage chambers to complete the synchronized support of the plant.

[0018] Second, when the arc-shaped top plate moves upward, the sealing plug can be moved out of the drip tube, allowing the water inside the water storage chamber to be discharged downward through the drip tube. By aligning the drip tube with the bottom center of the water storage chamber at an angle, the drip tube can drip water onto the roots of the plant. Watering the plant by dripping avoids rapid water loss and completes the function of drip watering the plant. Attached Figure Description

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 3As shown, a reusable biological protective tray for afforestation in sandy areas according to the present invention includes an accumulation mechanism 1. A connecting pipe 2 is fixedly installed at the top of the accumulation mechanism 1, and support bases 3 are symmetrically fixedly installed at the bottom of the accumulation mechanism 1. The accumulation mechanism 1 includes an alignment device 4 and a protective component 5. The alignment device 4 is symmetrically fixedly installed at the top of the protective component 5. The alignment device 4 includes a connecting top plate 6, a first rack 7, a first gear 8, an extension bracket 9, a top support plate 10, a hexagonal rod 11, a supporting vertical plate 12, a return spring 13, and a limiting rod 14. The extension bracket 9 is fixedly installed... The first gear 8 is rotatably mounted on the top of the extension bracket 9, and the hexagonal rod 11 is slidably inserted into the inner end of the top support plate 10 away from the extension bracket 9. The connecting top plate 6 is fixedly mounted on the top of the hexagonal rod 11. The return spring 13 is fixedly mounted between the top support plate 10 and the connecting top plate 6. The first rack 7 is fixedly mounted on the side end of the connecting top plate 6 near the first gear 8. The top support plate 10 is fixedly mounted on the top of the supporting vertical plate 12. The limiting rod 14 is fixedly mounted on the side end of the supporting vertical plate 12 away from the hexagonal rod 11.

[0033] like Figure 4 The protective component 5 includes a blocking device 15, a synchronizing device 16, and a supporting device 17. The blocking device 15 is slidably inserted into the top of the synchronizing device 16, and the synchronizing device 16 is fixedly installed on the top of the supporting device 17 to support the blocking device 15 in operation.

[0034] like Figure 5 The sealing device 15 includes an extension side frame 18, a sealing plug 19, a round rod 20, an L-shaped bracket 21, a second rack 22, an arc-shaped top plate 23, and a third rack 24. The extension side frame 18 is symmetrically fixedly installed on the outer ring of the arc-shaped top plate 23. The third rack 24 is fixedly installed on one end of the extension side frame 18 away from the arc-shaped top plate 23. The round rod 20 is fixedly installed on the bottom end of the arc-shaped top plate 23 and is arranged in a ring. The sealing plug 19 is fixedly installed on the bottom end of the round rod 20. The L-shaped bracket 21 is fixedly installed on both ends of the arc-shaped top plate 23 away from the third rack 24. The second rack 22 is fixedly installed on the top end of the L-shaped bracket 21 away from the arc-shaped top plate 23. When the arc-shaped top plate 23 moves downward, the sealing plug 19 can seal the drip tube 32.

[0035] like Figure 6The synchronization device 16 includes a support arm 25, a second gear 26, a support top seat 27, a round hole 28, a cover plate 29, a bolt 30, and a push plate 31. The bolt 30 is rotatably mounted on the top of the cover plate 29. The round hole 28 is opened on the top of the cover plate 29 near the bolt 30. The support top seat 27 is symmetrically fixedly mounted on the top of the cover plate 29. The second gear 26 is rotatably mounted on the top of both sides of the support top seat 27. The support arm 25 is fixedly mounted between the two second gears 26. The push plate 31 is fixedly mounted on the top of the support arm 25 away from the support top seat 27. When the push plate 31 rotates towards the center of the cover plate 29, it can get closer to the branches of the sapling, so that when the sapling is tilted, it can contact the push plate 31 and avoid excessive tilting of the sapling.

[0036] like Figure 7 The support device 17 includes a drip tube 32 and a water storage chamber 33. The drip tube 32 is fixedly installed at the bottom end of the water storage chamber 33 and is arranged in a ring. The drip tube 32 communicates with the inside of the water storage chamber 33. The water outlet hole in the drip tube 32 is small, so that the water inside the water storage chamber 33 can drip slowly downwards, avoiding rapid water loss.

[0037] The supporting vertical plate 12 is fixedly installed at both ends of the top of the cover plate 29, which is fixedly installed at the top of the water storage chamber 33. The third rack 24 meshes with the second gear 26. The connecting pipe 2 is fixedly connected to the round hole 28. The round rod 20 is slidably inserted into the inside of the cover plate 29. The arc-shaped top plate 23 is threaded onto the outer ring of the bolt 30. The second rack 22 meshes with the first gear 8 away from the outer ring of the first rack 7. The supporting base 3 is symmetrically fixedly installed at the bottom of the water storage chamber 33. The limiting rod 14 has a hexagonal hole inside. The supporting vertical plate 12 has a slot inside near the hexagonal rod 11 that matches the limiting rod 14. The arc-shaped top plate 23 is near the extension side frame. A threaded hole is provided inside the side end of 18. The sealing plug 19 is vertically aligned with the top end of the drip tube 32. The interior of the water storage chamber 33 is hollow and is interconnected with the drip tube 32. A plastic gasket is fixedly installed on the surface of the push plate 31. A round hole adapted to the round rod 20 is provided on the top end of the cover plate 29. A hexagonal hole adapted to the hexagonal rod 11 is provided inside the top support plate 10. The radius of the extension side frame 18 is 3 cm longer than that of the cover plate 29. The bottom of the side end of the first rack 7 away from the connecting top plate 6 meshes with the first gear 8. The top of the side end of the second rack 22 away from the arc top plate 23 meshes with the outer ring of the first gear 8 away from the side end of the first rack 7.

[0038] The working principle of Example 1 is as follows: In use, the sapling is first placed in a pre-dug hole in the ground, and then soil is covered around the roots. Subsequently, the water-retaining chambers 33 are moved towards each other until they are in contact. When the two water-retaining chambers 33 are in contact, the limiting rod 14 on one cover plate 29 is inserted into the supporting vertical plate 12 on the other cover plate 29 until the hexagonal rod 11 is perpendicularly aligned with the hexagonal slot in the limiting rod 14. Then, the bolt 30 is screwed on, and the arc-shaped top plate 23 is threaded onto the outer ring of the bolt 30. This allows the arc-shaped top plate 23 to simultaneously move the round rod 20 upwards. The round rod 20 slides inside the cover plate 29, ensuring that the arc-shaped top plate 23 moves upwards in a straight line. At this time, when the round rod 20 moves upward, it can drive the sealing plug 19 to move out from the top of the dripping tube 32. At this time, the water storage cavity 33 is interconnected with the inside of the dripping tube 32, so that water can be discharged downward from the dripping tube 32. Thus, the dripping tube 32 can slowly drip water onto the roots of the seedlings on the ground. At the same time, when the arc-shaped top plate 23 moves upward, it can drive the third rack 24 to move along the surface of the second gear 26, so that the second gear 26 can be rotated. When the second gear 26 rotates, it can drive the support arm 25 and the push plate 31 to rotate upward until the arc-shaped top plate 23 moves upward to the limit position, driving the push plate 31 to rotate and flip towards the center of the inside of the cover plate 29, so that the push plate 31 can get closer to the surface of the seedling and avoid the tree When seedlings are exposed to strong winds and tend to tilt or fall, this device provides reinforcement support. Simultaneously, as the arc-shaped top plate 23 moves upward, it also moves the second rack 22 on the side of the first gear 8 away from the first rack 7, causing the first gear 8 to rotate. When the first gear 8 rotates, it moves the first rack 7 downward, causing the connecting top plate 6 and the hexagonal rod 11 to move downward simultaneously. This allows the hexagonal rod 11 on one supporting vertical plate 12 to insert into the limiting rod 14 of the other supporting vertical plate 12, thus securing the two cover plates 29 and preventing them from falling off. This completes the merging and fixing of the two water storage chambers 33. In use, this device connects to the connecting pipe 2... An external water valve connection allows water to be opened, enabling water to be supplied to the water storage chamber 33 via the connecting pipe 2. Simultaneously, the two water storage chambers 33 are independently configured, but can be combined and fitted together, positioning them around the seedling. Then, the bolt 30 can be tightened to move the arc-shaped top plate 23 upwards, allowing the sealing plug 19 to no longer block the drip pipe 32. Water can then slowly drip from the drip pipe 32 to the roots of the seedling. Simultaneously, the upward movement of the arc-shaped top plate 23 also moves the third rack 24 upwards, causing the second gear 26 to rotate the push plate 31 closer to the inner center of the cover plate 29. This brings the push plate 31 closer to the surface of the seedling, providing support around it.To prevent saplings from tipping over in strong winds, and when the arc-shaped top plate 23 moves upward, it can drive the second rack 22 to move along the outer ring of the side of the first gear 8 away from the first rack 7, so that the first gear 8 can drive the first rack 7 to move downward. When the two water storage chambers 33 come into contact and merge, the limiting rods 14 on the two cover plates 29 can be inserted into the slots in the supporting vertical plate 12, so that the hexagonal rod 11 is vertically aligned with the hexagonal slot in the limiting rod 14. Subsequently, when the first rack 7 drives the connecting top plate 6 to move downward, it can drive the hexagonal rod 11 to insert into the limiting rod 14, thus preventing... A loosening and detachment occurred between the two water storage chambers 33. Furthermore, when the arc-shaped top plate 23 moved downwards, it caused the first gear 8 to rotate in the opposite direction, allowing the first rack 7 to move upwards. This enabled the hexagonal rod 11 to be removed from the limiting rod 14, unlocking the two water storage chambers 33. Subsequently, when the arc-shaped top plate 23 moved downwards, it caused the sealing plug 19 to be inserted into the drip tube 32, sealing the drip tube 32. Simultaneously, the third rack 24 moved downwards, causing the second gear 26 to rotate in the opposite direction, allowing the push plate 31 to move away from the seedling, facilitating the separation and disassembly of the two water storage chambers 33, thus completing the work.

[0039] Example 2

[0040] Based on Example 1, such as Figure 8 As shown, the support base 3 includes a screw 34, an extension plate 35, and a plug 36. The extension plate 35 is fixedly installed on the side of the support base 3 away from the storage mechanism 1. The screw 34 is threaded into the inside of the extension plate 35. The plug 36 is fixedly installed at the center of the bottom end of the screw 34.

[0041] When implementing this embodiment, when the device is placed on the ground, the screw 34 can be rotated. The threaded hole in the center of the extension plate 35 allows the insertion rod 36 to pass through the threaded hole in the extension plate 35 and contact the ground. Then, the screw 34 can be rotated to drive the insertion rod 36 to move downwards until the insertion rod 36 is inserted into the ground, thereby improving the stability of the support base 3 during operation and completing the work.

[0042] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
