Description

Technical fields:

[0001] This utility model relates to a burial device, and more particularly to a straw curtain and sand barrier burial device. Background technology:

[0002] As people's quality of life continues to improve, the issue of desertification is receiving increasing attention. To alleviate desertification and prevent the expansion of desert areas, it is necessary to stabilize sand dunes to prevent sand from drifting out of the desert with the monsoon. Currently, sand barrier stabilization is the most mature and widespread method in windbreak and sand fixation design. Strip-shaped vertical sand barriers involve inserting straw mats (including wheat straw mats, rice straw mats, and reed mats) into the sand, leaving a certain height exposed. Currently, the laying of strip-shaped vertical sand barriers is mostly done manually, using shovels to press down on the straw mats, causing the middle to bear the force and the ends to stand upright naturally. This method of installation is not only labor-intensive but also makes it difficult to control the burial depth, thus failing to achieve a good sand-sealing effect.

[0003] At present, the restoration of desertified land is achieved by planting plants in desertified land, that is, by planting grass seeds or tree seeds. However, due to the lack of water in desertified land, the survival rate of grass seeds is low, which leads to poor sand fixation effect. Utility model content:

[0004] The purpose of this utility model is to provide a straw mat sand barrier laying device that has a simple structure, reduces labor intensity, and improves the efficiency of straw mat laying.

[0005] This utility model is implemented by the following technical solution: The purpose of this patent is to provide a straw curtain sand barrier laying device, which includes a cart, wheels, a straw curtain laying structure and a straw curtain burying structure; the straw curtain laying structure and at least two straw curtain burying structures arranged side by side are arranged sequentially from front to back on the cart; the wheels are rotatably arranged on both sides below the cart between the straw curtain laying structure and the straw curtain burying structure.

[0021] Example: Figure 1-4As shown, a straw mat sand barrier laying device includes a cart 1, wheels 2, a straw mat laying structure 3, and a straw mat burial structure 4. The straw mat laying structure 3 and two parallel straw mat burial structures 4 are arranged sequentially from front to back on the cart 1. Wheels 2 are rotatably mounted on both sides below the cart 1 between the straw mat laying structure 3 and the straw mat burial structures 4. The straw mat laying structure 3 includes a mounting frame 31, on which two first straw mat rolls 32 are rotatably mounted side-by-side. The two first straw mat rolls 32 are positioned one above the other, with their inner edges overlapping to prevent gaps between the two flat-laid straw mats from leaking into the soil, thus ensuring... The two straw mats completely cover the land. A discharge port 11 is provided on the truck bed 1 below the mounting frame 31. Two parallel first guide rollers 33 are rotatably arranged in the discharge port 11. The free ends of the two first straw mat rolls 32 pass between the two first guide rollers 33 to guide the first straw mat rolls 32. The outer edges of the two first straw mat rolls 32 are placed under the corresponding wheels 2 to ensure that the first straw mat rolls 32 are unfolded and laid flat on the land surface during the forward movement. The straw mats are laid flat on the land surface where grass seeds are planted, which not only has the effect of preventing wind and fixing sand, but also has the effect of water retention and improving the survival rate of grass seeds.

[0022] The straw mat installation structure 4 includes a fixed frame 48 slidably mounted on the truck bed. A furrow opener 41, a support frame 42, and a straw pressing device 43 are arranged sequentially from front to back on the fixed frame 48. The furrow opener 41 is rotatably mounted on the fixed frame 48 below the truck bed 1 behind the wheel 2. A first hydraulic cylinder 44 is mounted at the bottom of the fixed frame 48, and the two ends of the first hydraulic cylinder 44 are rotatably hinged to the fixed frame 48 and the furrow opener 41, respectively. A support frame 42 is fixed on the fixed frame 48 above the truck bed 1, and a second straw mat roll 45 is rotatably mounted on the support frame 42. The free end of the second straw mat roll 45 passes under the straw pressing wheel 432 of the straw pressing device 43.

[0023] The straw pressing device 43 includes a frame 431, a straw pressing wheel 432, a soil covering plate 433, and a pressing wheel 434. The frame 431 is rotatably mounted on a fixed frame 48 below the truck bed 1. A second hydraulic cylinder 46 is located at the bottom of the fixed frame 48, with its two ends rotatably hinged to the fixed frame 48 and the frame 431, respectively. The straw pressing wheel 432 is rotatably mounted on the frame 431 behind the ditch opener 41. During its forward movement, it presses the second straw mat into the ditch opened by the ditch opener 41, causing the middle of the second straw mat to be stressed, while both ends... The straw mats stand upright naturally, forming a strip-shaped vertical sand barrier, which reduces labor intensity, improves the efficiency of straw mat installation, and ensures the installation depth, achieving a good sand sealing effect. A soil covering plate 433 is rotatably installed under the frame 431 on both sides behind the straw pressing wheel 432, covering the sides of the erected second straw mat with soil during forward movement. A pressing wheel 434 is rotatably installed under the frame 431 behind each soil covering plate 433, compacting the soil on both sides of the erected second straw mat during forward movement to prevent it from being blown down by the wind later.

[0024] A second guide roller 47 is rotatably arranged below the fixed frame 48 to guide the second straw roll 45. The second guide roller 47 is located between the ditch opener 41 and the straw pressing device 43. The free end of the second straw roll 45 passes under the second guide roller 47 and the straw pressing wheel 432 of the straw pressing device 43 in sequence.

[0025] Several guide rods 5 are fixed on the fixed frame 48, and several guide sleeves 6 that match the guide rods 5 are fixed on the surface of the truck bed. The guide rods 5 move through the guide sleeves 6 in sequence to ensure that the fixed frame 48 moves along the extension and retraction direction of the third hydraulic cylinder 7. A third hydraulic cylinder 7 with an extension and retraction direction perpendicular to the truck bed's movement direction is fixed on the surface of the truck bed, and the extension and retraction end of the third hydraulic cylinder 7 is fixed on the fixed frame 48.

[0026] like Figure 5 As shown, when it is necessary to lay the straw mat, the first hydraulic cylinder 44 and the second hydraulic cylinder 46 are controlled to retract, the ditch opener 41 and the frame 431 are retracted, the second straw mat roll 45 is retracted, the free end of the first straw mat roll 32 passes between the two first guide rollers 33, and then presses under the two wheels 2. Then the tractor starts to move forward, driving the truck bed 1 forward, and the rotating wheels 2 lay the first straw mat on the ground.

[0027] like Figure 6 As shown, when it is necessary to bury strip-shaped vertical sand barriers, the first straw curtain roll 32 is retracted, and the third hydraulic cylinder 7 is controlled to extend or retract to adjust the spacing between the two straw curtain burying structures 4 so that it meets the spacing requirements between adjacent strip-shaped vertical sand barriers. Then, the second straw curtain roll 45 is unfolded, and its free end passes around the second guide roller 47 and is placed below the straw pressing device 43. Then, the first hydraulic cylinder 44 and the second hydraulic cylinder 46 are controlled to extend, and the trench opener 41 and the frame 431 are lowered. The straw pressing wheel 432 presses the middle of the second straw curtain and continues to press downward so that its two ends stand up naturally. Then, the tractor starts to move forward, driving the truck bed 1 forward, and begins to bury the strip-shaped vertical sand barriers.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
