Description

Technical Field

[0001] The invention relates to the technical field of sandy land afforestation, in particular to a reusable biological protective plate for sandy land afforestation. Background Art

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

[0003] In the field of desert afforestation or sandy afforestation, biological protection tray usually refers to a device used to improve the survival rate of young trees. This biological protection tray is usually disc-shaped, with a certain thickness and diameter, a round hole in the middle, and a notch connected to the outside. The main function of the biological protection tray is to resist the rapid evaporation of soil moisture caused by continuous wind, and at the same time it can increase the soil temperature in the root layer, thereby helping the growth and survival of young trees.

[0004] At present, the biological protection trays for afforestation in sandy land on the market are often abandoned after use due to their simple structural settings.

[0036] like Figure 7 The supporting device 17 includes a dripping tube 32 and a water storage cavity 33. The dripping tube 32 is fixedly installed at the bottom end of the water storage cavity 33, and the dripping tube 32 is distributed in a ring shape. The dripping tube 32 is interconnected with the inside of the water storage cavity 33, and the water outlet hole in the dripping tube 32 is small, so that the water inside the water storage cavity 33 can slowly drip downward to avoid rapid loss of water.

[0037] The support vertical plate 12 is fixedly mounted on both ends of the top of the cover plate 29, the cover plate 29 is fixedly mounted on the top of the water storage cavity 33, the third rack 24 is meshed with the second gear 26, the connecting pipe 2 is fixedly connected to the circular hole 28, the round rod 20 is slidably inserted into the inside of the cover plate 29, the arc top plate 23 is threadedly sleeved on the outer ring of the bolt 30, the second rack 22 is meshed with the outer ring of the first gear 8 away from the first rack 7, the support foot 3 is symmetrically fixedly mounted on the bottom end of the water storage cavity 33, a hexagonal hole is opened inside the limiting plug rod 14, a slot adapted to the limiting plug rod 14 is opened inside the support vertical plate 12 near the hexagonal rod 11, and the arc top plate 23 is close to 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 cavity 33 is arranged in a hollow state, and the water storage cavity 33 and the drip tube 32 are interconnected, a plastic gasket is fixedly installed on the surface of the push plate 31, a round hole compatible with the round rod 20 is provided on the top of the cover plate 29, and a hexagonal hole compatible with the hexagonal rod 11 is provided inside the top support plate 10. The extended side frame 18 is 3 cm longer than the radius of the cover plate 29. The bottom of the side end of the first rack 7 away from the connecting top plate 6 is meshed with the first gear 8, and the top of the side end of the second rack 22 away from the arc top plate 23 is meshed with the outer ring of the side end of the first gear 8 away from the first rack 7.

[0038] The working principle of Example 1 is as follows: when in use, first place the sapling in a hole dug in advance on the ground, then cover the roots of the sapling with soil, and then move the water storage cavities 33 toward each other until the two water storage cavities 33 fit together. At this time, when the two water storage cavities 33 fit together, the limiting rod 14 on one cover plate 29 can be driven to insert into the supporting vertical plate 12 on the other cover plate 29 until the hexagonal rod 11 is vertically aligned with the hexagonal groove in the limiting rod 14, and then the bolt 30 is screwed and rotated, and the arc top plate 23 is threadedly sleeved on the outer ring of the bolt 30, so that the arc top plate 23 can drive the round rod 20 to move upward at the same time, and the round rod 20 slides inside the cover plate 29, so that the arc top plate 23 can be guaranteed to move upward 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 drip tube 32. At this time, the water storage cavity 33 is interconnected with the inside of the drip tube 32, so that water can be discharged downward from the drip tube 32, so that the drip tube 32 can slowly drip water onto the roots of the saplings on the ground. At the same time, when the arc 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 driven to rotate. When the second gear 26 rotates, it can drive the support arm 25 and the push plate 31 to rotate upward until the arc top plate 23 moves upward to the limit position, driving the push plate 31 to rotate and flip in the direction close to the inner center of the cover plate 29, so that the push plate 31 can be close to the surface of the sapling to avoid the sapling. When the seedlings encounter strong winds, they tilt and fall, and the work of strengthening the support for the seedlings is completed. At the same time, when the arc top plate 23 moves upward, it can also drive the second rack 22 to move on the side end of the first gear 8 away from the first rack 7, so that the first gear 8 can be driven to rotate. When the first gear 8 rotates, it can drive the first rack 7 to move downward, so that the first rack 7 can drive the connecting top plate 6 and the hexagonal rod 11 to move downward at the same time, so that the hexagonal rod 11 on one supporting vertical plate 12 can be inserted into the limiting plug rod 14 of the other supporting vertical plate 12, so that the two cover plates 29 can be restricted and fixed to prevent the two cover plates 29 from falling off, and the work of merging and fixing the two water storage chambers 33 to each other is completed. When the device is in use, the connecting pipe 2 and The external water valve is connected, the water valve can be opened, so that the connecting pipe 2 can transport water to the inside of the water storage cavity 33. At the same time, the two water storage cavities 33 are independently arranged, so that the two water storage cavities 33 can be merged and fitted together, so that the water storage cavity 33 can be located at the periphery of the sapling. Subsequently, the bolt 30 can be screwed and rotated so that the arc top plate 23 can be displaced upward, so that the sealing plug 19 can no longer block the drip tube 32, so that water can be slowly dripped from the drip tube 32 to the root of the sapling. At the same time, when the arc top plate 23 is displaced upward, it can also drive the third rack 24 to move upward, so that the second gear 26 can drive the push plate 31 to flip toward the inner center close to the cover plate 29, so that the push plate 31 can be close to the surface of the sapling and can form a support around the sapling.In order to prevent the saplings from falling over when encountering strong winds, when the arc top plate 23 moves upward, the second rack 22 can be driven to move along the outer ring of the side end 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 cavities 33 are in contact and merged, the limiting rods 14 on the two cover plates 29 can be inserted into the slots in the supporting vertical plates 12, so that the hexagonal rod 11 is vertically aligned with the hexagonal groove in the limiting rod 14. Subsequently, when the first rack 7 drives the connecting top plate 6 to move downward, the hexagonal rod 11 can be driven to be inserted into the limiting rod 14, so that the saplings can be prevented from falling over when encountering strong winds. There is a phenomenon of loosening and falling between the two water storage chambers 33, and when the arc top plate 23 moves downward, it can drive the first gear 8 to rotate in the opposite direction, so that the first rack 7 can move upward, so that the hexagonal rod 11 can be moved out of the limiting rod 14, and the two water storage chambers 33 can be unlocked. Then, when the arc top plate 23 moves downward, it can drive the sealing plug 19 to insert into the drip tube 32, and the drip tube 32 can be closed. At the same time, the third rack 24 can move downward, driving the second gear 26 to rotate in the opposite direction, so that the push plate 31 can be away from the sapling, which is convenient for the separation and disassembly of the two water storage chambers 33 to complete the work.

[0039] Example 2

[0040] On the basis of Example 1, Figure 8 As shown, the supporting base 3 includes a screw 34, an extension plate 35 and an insert rod 36. The extension plate 35 is fixedly mounted on the side end of the supporting base 3 away from the accumulation mechanism 1. The screw 34 is threadedly inserted into the extension plate 35, and the insert rod 36 is fixedly mounted at the bottom center of the screw 34.

[0041] When implementing this embodiment, when the device is placed on the ground, the screw rod 34 can be screwed and rotated, and a threaded hole is opened through the inner center of the extension plate 35. The insertion rod 36 can be passed through the threaded hole in the extension plate 35 to contact the ground, and then the screw rod 34 is screwed and rotated to drive the insertion rod 36 to continue to move downward until the insertion rod 36 is inserted under the ground, so that the stability of the support base 3 during operation can be improved to complete the work.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
