Description

Technical Field

[0001] This utility model relates to the field of sand barrier laying machinery, and in particular to a roller-type grass sand barrier laying machinery seeding device. Background Technology

[0002] Grass sand barriers are a type of sand-blocking measure built using plants, also known as biological sand barriers. Their main function is to prevent wind erosion and sand accumulation, and to alter wind action and micro-topography. This is achieved by planting living shrubs and herbaceous plants. Compared to mechanical sand barriers, biological sand barriers have advantages such as lower cost, longer and more stable effect, and can improve the physical and chemical properties of sandy land, greening and beautifying the desert environment. However, the high technical difficulty of construction and the high management requirements are disadvantages of grass sand barriers. Strong wind erosion causes mechanical sand barriers to generally lose their windbreak and sand-fixing function in about 5 years. Biological sand barriers are constructed by utilizing the wind-blocking function of mechanical sand barriers before they become ineffective.

[0003] There are three main methods for establishing grass-based sand barriers: direct seeding, cutting propagation, and seedling planting. Selecting suitable plant species is the most crucial technical step in establishing grass-based sand barriers, as the suitable plant species will vary depending on the differences in climate, soil, hydrology, vegetation, and other comprehensive natural conditions in different natural zones. During seed sowing, it is necessary to adjust the sowing density as needed to avoid overly dense or sparse sowing, and to ensure the burial depth is sufficient to prevent wind and sand from blowing the seeds away or leaving them completely buried. Summary of the Invention

[0026] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0027] This application includes a loading vehicle 1 identical to the prior art. The loading vehicle 1 is symmetrically equipped with moving wheels 11. A seed box 4 for storing seeds is fixedly connected to the loading vehicle 1. The seed box 4 is a rectangular and hollow design that gradually tapers from top to bottom. A hopper 42 is detachably connected to the bottom of the seed box 4. Depending on the anchoring characteristics, wire, bolts, etc. can be used for connection. A conduit 43 is fixed and connected to the hopper 42. Seeds falling into the hopper 42 fall to the ground through the conduit 43. An adjustment component for controlling the falling speed of the seeds is provided inside the seed box 4. A power component for providing power to the adjustment component is connected to the adjustment component. The power component is detachably connected to one of the moving wheels 11. When the moving wheel 11 is connected to the power component, the moving wheel 11 rotates to provide running power to the power component and transmits the power to the adjustment component through the power component.

[0028] The adjusting assembly includes a drive shaft 5. One end of the drive shaft 5, away from the loading vehicle 1, is connected to a seed-measuring wheel 51 for controlling the seed falling speed. The seed-measuring wheel 51 is slidably connected to the seed box 4 through a first locking hole 41. When the drive shaft 5 rotates, the seed-measuring wheel 51 does not rotate with it. The speed at which seeds fall from the seed box 4 into the hopper 42 is controlled by driving the seed-measuring wheel 51 to move horizontally along the length of the drive shaft 5. The larger the area of ​​the seed-measuring wheel 51 inserted into the seed box 4, the slower the seed falling speed. A seed-discharging wheel 52 is movably connected to the other end of the drive shaft 5. The seed wheel 52 is rotatably connected to one end of the seed box 4. When the drive shaft 5 rotates, the seed-lowering wheel 52 rotates in the same direction and at the same speed, which is used to transport the seeds falling on the seed-lowering wheel 52 to the bottom of the seed box 4 and fall into the hopper 42. The seed-controlling wheel 51 is in contact with the seed-lowering wheel 52, so that the falling speed of the seeds can be changed by adjusting the horizontal position of the seed-controlling wheel 51 and the seed-lowering wheel 52. When the seed-controlling wheel 51 moves into the seed box 4, the seed-lowering wheel 52 moves in the opposite direction, and the contact area between the seed-lowering wheel 52 and the seeds is reduced, thereby reducing the falling space of the seeds and thus changing the falling speed of the seeds.

[0029] Two fixed clamps 54 are detachably connected to both ends of the drive shaft 5, and the two fixed clamps 54 abut against the seed measuring wheel 51 and the seed lowering wheel 52, respectively. The horizontal position of the seed measuring wheel 51 and the seed lowering wheel 52 is fixed by adjusting the fixed clamps 54. When the operator needs to change the seed falling rate, the two fixed clamps 54 are loosened to move the seed measuring wheel 51 and the seed lowering wheel 52 in the specified direction. After the movement is completed, the two fixed clamps 54 are tightened to ensure that the horizontal position of the seed measuring wheel 51 and the seed lowering wheel 52 remains fixed during the rotation of the drive shaft 5.

[0030] The power assembly includes a rotating sleeve 2, on which a friction wheel 21 is connected for connection with one of the movable wheels 11. A connecting rod is provided on the friction wheel 21, and the connecting rod is slidably connected to the rotating sleeve 2, thereby changing the distance between the friction wheel 21 and the rotating sleeve 2, and realizing the detachable connection between the friction wheel 21 and the movable wheel 11. A driving wheel 22 is connected to the rotating sleeve 2, and a driven wheel 53 is connected to the transmission shaft 5. The driving wheel 22 and the driven wheel 53 are connected by a hinge. The rotation of the driving wheel 22 drives the driven wheel 53 to rotate through the hinge, thereby providing power for the rotation of the transmission shaft 5.

[0031] A fixed frame 3 is fixedly connected to the loading vehicle 1. The connecting rod and the transmission shaft 5 are rotatably connected to the two ends of the fixed frame 3, respectively. A transmission rod 31 is slidably connected to the fixed frame 3. A transmission part B33 is connected to the end of the transmission rod 31 near the drive wheel 22. The transmission part B33 abuts against the friction wheel 21. The contact area between the transmission part B33 and the friction wheel 21 is changed by driving the transmission rod 31 to move horizontally along the length direction of the fixed frame 3. An inclined guide plate is provided at the contact end of the transmission part B33 and the friction wheel 21. When the transmission part B33 moves toward the friction wheel 21, the guide plate can push the friction wheel 21 toward the nearby moving wheel 11 and make contact with it to achieve friction transmission.

[0032] Friction balls 34 are symmetrically arranged on the end face of the transmission part B33 facing the drive wheel 22. The friction balls 34 are nested on the transmission part B33 and abut against the friction wheel 21. When the friction wheel 21 rotates, the friction balls 34 can rotate in the same direction to reduce the friction between them and the friction wheel 21, thereby reducing the consumption in the power transmission process.

[0033] A control rod 35 is slidably connected to the fixed frame 3. A transmission part A32 is provided on the other end of the transmission rod 31. A pushing part is provided at the contact end of the control rod 35 and the transmission part A32. The pushing part is slidably connected to the transmission part A32. A compression spring is sleeved on the transmission rod 31. The two ends of the compression spring are respectively connected to the transmission part A32 and the fixed frame 3. Pushing the control rod 35 will drive the transmission rod 31 to move in the direction of the friction wheel 21, thereby controlling the transmission part B33 to move in the same direction. During the movement of the transmission rod 31, the compression spring contracts and generates a reverse force. Its reverse force cannot push the control rod 35 to move in the opposite direction. However, when the worker grasps the control rod 35 and moves it upward, the compression spring can push the transmission rod 31 to move in the opposite direction, causing the friction wheel 21 to separate from the moving wheel 11 of the foundation, thereby stopping the operation of the adjustment component.

[0034] When using this device, the operator drives the tractor to move the loading vehicle 1 in the designated direction. When sowing is required along the moving path, the operator presses down the control lever 35, causing the friction wheel 21 to contact the moving wheel 11, which in turn drives the drive wheel 22 to rotate in the same direction and at the same speed. The drive wheel 22 then transmits power to the driven wheel 53 through a hinge, causing the drive shaft 5 to rotate. The seed-laying wheel 52 rotates in the same direction, causing the seeds falling on it to fall to the bottom of the seed box 4 and into the hopper 42. The seeds are then sown to the ground through the guide tube 43 connected to the hopper 42. The seeds come out of the guide tube 43, slide along the side behind the moving wheel 11, and enter the sand barrier at a depth of about 5 cm. Generally, wind and sand can bury the seeds 5 cm below the surface in the sand barrier.

[0035] This application also includes a second embodiment, which differs from the first embodiment in that a bearing 56 is connected to the control measuring wheel 51, the bearing 56 is slidably connected to the drive shaft 5, and the control measuring wheel 51 is rotatably connected to the bearing 56. One or more fixing holes 55 are symmetrically arranged at both ends of the drive shaft 5, and the fixing holes 55 are evenly spaced along the length of the drive shaft 5. A second locking hole 57 is provided on both the bearing 56 and the lower measuring wheel 52, and a locking part is inserted into the second locking hole 57. The bottom end of the locking part is inserted into the corresponding fixing hole 55. The locking part can be a key, bolt, etc., depending on the anchoring characteristics. When it is necessary to adjust the horizontal position of the lower measuring wheel 52 and the control measuring wheel 51, the locking part is pulled out and pushed to the designated position, and then the locking part is inserted into the corresponding fixing hole 55 for fixation.

[0036] This application also includes a third embodiment, which differs from the second embodiment in that both the bearing 56 and the lower sub-roller wheel 52 are threadedly connected with fixing bolts 58, and the tail end of the fixing bolts 58 abuts against the drive shaft 5. By rotating the fixing bolts 58 to make the outer wall of the drive shaft 5 interference fit, the control sub-roller wheel 51 and the lower sub-roller wheel 52 are fixed.
