Description

Technical Field

[0001] This utility model relates to the field of windbreak and sand fixation technology, and in particular to a device for constructing sand barriers in dune terrain. Background Technology

[0002] Years of afforestation and sand fixation have enabled my country to achieve a good trend of continuous reduction and enhanced function in desertification control. Continuous practice and summarization have proved that sand fixation must come first in sand control. Straw checkerboards can increase surface roughness, reduce near-surface wind speed, and at the same time create a stable sandy environment for soil crust development, seed implantation of sand plants, and seedling planting.

[0003] Years of desertification control practice have proven that straw checkerboards are one of the most effective methods for fixing shifting sand. However, the terrain of sandy areas is complex and diverse, with undulating dunes and significant slope variations. The size of the straw checkerboards needs to be selected according to the regional wind conditions and terrain. The checkerboard sizes include 1.5m×1.5m and 1m×1m. Currently, most sandy areas still use the traditional manual laying method, which involves manually pressing straw stalks into the sand from the middle with a blunt shovel. The depth of insertion into the sand is 15-25cm, and the height protruding from the sand surface is 15-25cm. Straw checkerboards can reduce ground wind speed by more than 40 times. After 3-4 years, the straw can be re-tied after it decomposes. This cycle continues, with organic matter depositing on the surface of the sand layer to form a sand crust, which eventually becomes a natural protective film on the surface of the sand, thus fixing the shifting sand. However, due to the harsh working environment in the desert, the workload of manually laying grass checkerboard sand barriers is large. In addition, the terrain factors (some sand dunes have a slope of >10°) increase the difficulty of planting and reduce the efficiency of laying the barriers, requiring the cooperation of many people.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, this utility model provides a device for constructing sand barriers in dune terrain, including a cart frame 1, a power system 11 and a walking mechanism 13 mounted on the cart frame 1. The walking mechanism 13 is located at the bottom of the cart frame 1. The cart frame 1 is equipped with a push handle 12 and includes a grass-pressing mechanism 2. The grass-pressing mechanism 2 includes a grass-pressing frame 21 and a grass-pressing drive system 22 and a grass-pressing wheel 23 mounted on the grass-pressing frame 21. The grass-pressing wheel 23 is driven by the grass-pressing drive system 22 and can rotate. The cart frame 1 is located at... A connecting frame 14 is provided at one end away from the push handle 12. The grass pressing frame 21 is adjustablely connected to the connecting frame 14. A frame driving mechanism 15 is provided on the connecting frame 14. The grass pressing frame 21 is driven by the frame driving mechanism 15 and can move up and down along the connecting frame 14. The walking mechanism 13 includes a driving walking wheel 131 and a walking auxiliary wheel 132. The trolley bracket 1 is provided with an operating mechanism for the walking auxiliary wheel 132 to be put away and put away. The walking auxiliary wheel 132 is driven by the operating mechanism and has a put-away state and a walking state.

[0025] Specifically, the trolley bracket 1 is used for the installation of the power system 11 and the walking mechanism 13. The power system 11 is mounted on the trolley bracket 1 and provides power to the walking mechanism 13. The walking mechanism 13 is located at the bottom of the trolley bracket 1 and includes two driving wheels 131 and two auxiliary driving wheels 132 arranged opposite each other. The two driving wheels 131 are located at the end of the trolley bracket 1 near the push handle 12. The driving wheels 131 are connected to the power system 11 and can drive the driving wheels 131. The rotation of the driving wheels 131 allows the trolley bracket 1 to walk on the sand. Two push handles 12 are provided at one end of the trolley bracket 1. A control system is provided on the push handle 12 and is connected to the power system 11. The control system can control the walking speed and direction of the trolley bracket 1. This is prior art and will not be described in detail.

[0026] In this embodiment, two walking auxiliary wheels 132 are located on the side of the cart support 1 away from the cart handle. The cart support 1 is equipped with an operating mechanism for retracting and extending the walking auxiliary wheels 132. Depending on the use of the cart support 1 and the hay-pressing mechanism 2, the walking auxiliary wheels 132 are driven by the operating mechanism to have a retracted state and a walking state. When the hay-pressing mechanism 2 is not working, the cart support 1 and the hay-pressing mechanism 2 only move without performing hay-pressing operations, and the walking auxiliary wheels 132 are in the walking state. This drives the walking wheels 131 and the walking auxiliary wheels 132. The combined action of wheels 132 enables the cart support 1 and the straw pressing frame 21 to move on sand or other surfaces. When the straw pressing mechanism 2 needs to work to perform straw pressing operations, the walking auxiliary wheels 132 are in a retracted state. In this way, the walking auxiliary wheels 132 do not contact the sand, but only through the driving walking wheels 131 and the straw pressing wheels 23. The position of the straw pressing wheels 23 is lower than the position of the driving walking wheels 131. The driving walking wheels 131 provide power for the movement of the entire device, and the straw pressing wheels 23 press the straw into the sand.

[0027] In this embodiment, the straw pressing mechanism 2 includes a straw pressing frame 21, a straw pressing drive system 22, and a straw pressing wheel 23. The straw pressing drive system 22 is installed on the straw pressing frame 21, and the straw pressing wheel 23 is installed at the bottom of the straw pressing frame 21. The straw pressing wheel 23 is connected to the straw pressing drive system 22 for transmission. The straw pressing drive system 22 can drive the straw pressing wheel 23, so that the straw pressing wheel 23 can rotate and press the straw into the sand. The end of the cart support 1 away from the push handle 12 is provided with a connecting frame 14. The connecting frame 14 includes an integrally formed vertical frame and a horizontal frame. The horizontal frame is installed on the top of the vertical frame, and the straw pressing frame 21 is adjustablely connected to the vertical frame.

[0028] A frame drive mechanism 15 is provided on the connecting frame 14. The frame drive mechanism 15 can be set on a horizontal frame. The lower end of the frame drive mechanism 15 is connected to the grass-pressing frame 21. The grass-pressing frame 21 is driven by the frame drive mechanism 15 and can move up and down along the connecting frame 14. The frame drive mechanism 15 can be a structure of multiple cooperating hydraulic pistons. When the grass-pressing mechanism 2 is not working, the multiple hydraulic pistons drive the grass-pressing frame 21, thereby causing the grass-pressing frame 21 to move upward. This causes the position of the grass-pressing wheel 23 to be higher than the height of the driving wheel 131, so that the grass-pressing wheel 23 leaves the sand (no longer in contact with the sand). The combined action of the driving wheels 131 and 132 enables the cart support 1 and the straw pressing frame 21 to move on sand or other surfaces. When the straw pressing mechanism 2 needs to perform straw pressing operations, multiple hydraulic pistons drive the straw pressing frame 21, causing it to move downwards. This lowers the position of the straw pressing wheel 23 below the height of the driving wheels 131, preventing the 132 from contacting the sand. The driving wheels 131 and 23 then contact the sand, providing power for the entire device to move. The straw pressing wheel 23 presses the straw into the sand.

[0029] This utility model provides a device for constructing sand barriers in dune terrain, including a trolley frame 1, a power system 11 and a walking mechanism 13 mounted on the trolley frame 1, a grass-pressing mechanism 2 including a grass-pressing frame 21, a grass-pressing drive system 22 and grass-pressing wheels 23 mounted on the grass-pressing frame 21, a connecting frame 14 at the end of the trolley frame 1 away from the push handle 12, the grass-pressing frame 21 being adjustablely connected to the connecting frame 14, a frame drive mechanism 15 mounted on the connecting frame 14, a walking support including a drive wheel 131 and a walking auxiliary wheel 132, and an operating mechanism for extending and retracting the walking auxiliary wheel 132 mounted on the trolley frame 1. The wheel 132 is driven by the operating mechanism and has a retracted state and a walking state. In use, when the straw pressing wheel 23 is off the ground and the walking auxiliary wheel 132 is in the walking state, the device formed by the trolley bracket 1 and the straw pressing mechanism 2 can walk on sand and other roads, so that the device can be easily moved to a suitable position. When it is necessary to lay straw grids for sand control, the walking auxiliary wheel 132 is in the retracted state and the height of the straw pressing wheel 23 is lower than the height of the driving walking wheel 131. The driving walking wheel 131 provides power for the entire device to walk, and the straw pressing wheel 23 presses the straw into the sand, improving work efficiency.

[0030] In this embodiment, preferably, a wheel mounting rod 133 is rotatably mounted on the trolley bracket 1, and a walking auxiliary wheel 132 is rotatably mounted on the bottom of the wheel mounting rod 133. The operating mechanism includes an operating piston rod 134, the upper end of which is connected to the trolley bracket 1 and is rotatably connected to the trolley bracket 1. The lower end of the operating piston rod 134 is connected to the lower end of the wheel mounting rod 133 and is also rotatably connected to the lower end of the wheel mounting rod 133. The operating piston rod 134 is inclined, and the wheel mounting rod 133 can be rotated by driving the operating piston rod 134. When the wheel mounting rod 133 moves to the vertical direction, the wheel mounting rod 133 and the walking auxiliary wheel 132 are in a walking state. When the wheel mounting rod 133 is driven to rotate away from the sand, the wheel mounting rod 133 and the walking auxiliary wheel 132 are in a retracted state.

[0031] In this embodiment, preferably, an auxiliary grass-pressing mechanism 3 is also included. The auxiliary grass-pressing mechanism 3 is located at the end of the grass-pressing frame 21 away from the cart support 1. The auxiliary grass-pressing mechanism 3 includes a mounting frame 31 and a grass-pressing component 32. The mounting frame 31 includes a vertical mounting beam 311 arranged opposite to each other and a top crossbeam 312 arranged on the top of the vertical mounting beam 311. The mounting frame 31 is vertically fixedly mounted on the cart support 1. The vertical mounting beam 311 and the top crossbeam 312 form a door-shaped mounting frame 31. The vertical mounting beam 311 is fixedly mounted to the cart support 1. A lifting drive unit 33 is provided on the mounting frame 31. The grass-pressing component 32 is driven by the lifting drive unit 33 and can move up and down along the mounting frame 31.

[0032] In this embodiment, preferably, the mounting frame 31 is provided with a motion seat 34 that is transmissionally connected to the lifting drive unit 33. The motion seat 34 is provided with a sliding member 341. Two sliding members 341 are respectively provided on opposite sides of the motion seat 34. The sliding members 341 are slidably connected to the mounting frame 31. A vertical slide groove is provided on the vertical mounting beam 311. The sliding member 341 is slidably connected in the vertical slide groove and can move up and down along the vertical slide groove. The lifting drive unit 33 can be a hydraulic piston or other structure. The lower end of the hydraulic piston rod is connected to the motion seat 34. Thus, the hydraulic piston rod can be driven to move up and down along the vertical mounting beam 311 by the hydraulic piston.

[0033] In this embodiment, preferably, the grass-pressing assembly 32 includes a grass-pressing bracket 322 and a cylindrical grass-pressing component 321 disposed on the grass-pressing bracket 322. The grass-pressing bracket 322 includes a first side plate 323 and a second side plate 324 disposed opposite to each other. A mounting rod 342 is disposed on the motion seat 34. One end of the first side plate 323 and one end of the second side plate 324 are rotatably connected to the mounting rod 342. The cylindrical grass-pressing component 321 is rotatably connected to the other end of the first side plate 323 and the second side plate 324. The first side plate 323 and the second side plate 324 are respectively connected to the first side plate 323 and the second side plate 324. A connecting beam 325 is provided in the middle of the two side plates 324. An angle driving component 35 is provided on the mounting frame 31. The angle driving component 35 can also be a hydraulic piston or other structure. The upper end of the angle driving component 35 is rotatably connected to the mounting frame 31, and the lower end of the angle driving component 35 is rotatably connected to the connecting beam 325. A grass pressing disc 326 and a grass pressing toothed disc 327 are provided on the columnar grass pressing component 321. The grass pressing disc 326 and the grass pressing toothed disc 327 are arranged alternately along the axial direction of the columnar grass pressing component 321.

[0034] In this way, during use, the height of the moving seat 34 and the straw pressing bracket 322 can be adjusted by the lifting drive unit 33, and the angle of the straw pressing bracket 322 can be adjusted by the angle drive component 35. When the angle drive component 35 drives the straw pressing bracket 322, it drives the connecting beam 325, and the first side plate 323 and the second side plate 324 rotate relative to the mounting rod 342, so that the columnar straw pressing component 321 is adjusted to a suitable angle and height. During the straw pressing operation, there is a certain gap between the columnar straw pressing component 321 and the sand. The lifting drive unit 33 and the angle drive component 35 keep the columnar straw pressing component 321 at a suitable height and angle. Thus, when the straw pressing wheel 23 presses the straw into the sand, the columnar straw pressing component 321, the straw pressing disc 326 and the straw pressing toothed disc 327 can sort the straw.
