Description

Technical Field

[0001] This invention relates to the field of sand willow mesh sand barrier laying technology, and more specifically, to a one-time molding sand willow mesh sand barrier laying device and laying method. Background Technology

[0002] Sand willow (Salix psammophila) is a psammophytic shrub. It is highly resilient, easy to propagate, and has a strong ability to sprout new shoots, which easily survive and grow. Due to its advantages in controlling wind erosion, sand willow is widely planted in Northwest my country as an excellent plant species for windbreak and sand fixation, with large numbers of natural and artificial sand willows distributed throughout the region. After being coppiced in the desert, sand willow produces a large number of branches, providing ideal natural raw materials for the construction of sand willow sand barriers. Sand willow mesh sand barriers can effectively stabilize sand, promote vegetation restoration, and improve the ecological environment of desert areas.

[0003] Currently, desert areas face numerous problems such as inconvenient transportation and sparse population. Sand barriers are typically laid manually or mechanically. Manual labor is labor-intensive, costly, produces poor quality, and is inefficient, resulting in a desertification control rate far slower than the actual desertification rate, failing to effectively alleviate desertification. Mechanical methods, such as the existing patent for a tall, upright branch and straw sand barrier laying machine (application number: CN202210319649.4), are another option. This sand barrier laying machine includes a frame supporting various mechanisms, a power transmission mechanism at the front of the frame, a grabbing mechanism in the middle of the frame, a tamping mechanism at the rear of the frame, a feeding mechanism at the top of the frame, and a traveling mechanism at the bottom of the frame. It uses tall, upright sand barriers made of branches and straw for insertion and laying. The insertion process is a cyclical motion, controlled by the power transmission mechanism, with two different parts of the operation alternating. Two adjacent operations constitute one cycle, completing one complete sand barrier insertion operation. The machine then moves to the next working position, thus laying the sand barrier at equal intervals. Laying using grippers results in a relatively complex structure, and the process of gripping, aligning, and inserting the cuttings is relatively inefficient. Summary of the Invention

[0004] The technical problem to be solved by this invention is:

[0005] To address the problem that existing sand barrier laying devices rely on robotic arms to insert and fix sand willows, which are relatively complex in structure and inefficient.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] This invention provides a one-piece molded sand willow mesh sand barrier laying device, including a storage bin, an extrusion sorting mechanism, a branch conveying mechanism, a soil covering mechanism, a tracked chassis, a reversing mechanism, and a drive mechanism.

[0008] The drive mechanism is used to drive the tracked chassis, thereby driving the sand barrier laying device forward or backward, and the reversing mechanism is used to control the movement direction of the sand barrier laying device.

[0009] The tracked chassis is equipped with a compression sorting mechanism, which is located inside the storage bin and at the bottom of the storage bin. The compression sorting mechanism includes a triangular conveyor belt and a long straight conveyor belt that rotate in opposite directions. The triangular conveyor belt is located above one side of the long straight conveyor belt, and the distance between the two is matched with the diameter of a sand willow tree.

[0010] Below the output ends of the triangular conveyor belt and the long straight conveyor belt, there is a branch conveying mechanism. The branch conveying mechanism includes a base frame, guide rails, branch conveying carriage, and crank rocker. The base frame is a frame structure, and guide rails are provided on both sides of the base frame. Each guide rail has evenly spaced grooves, and the grooves on the two guide rails correspond one-to-one. There are two levers parallel to the guide rails between the two guide rails. The two ends of the levers are respectively connected to one end of the crank rocker, and the other end of the crank rocker is connected to the base frame.

[0011] Below the output end of the branch conveying mechanism is a branch insertion mechanism. The branch insertion mechanism includes a feeding hopper and two sets of cross-arranged vertical roller structures. Each set of roller structures includes a fixed-axis pressure roller and a movable pressure roller. The fixed-axis pressure roller and the movable pressure roller are rotatably connected to the tracked chassis.

[0012] Furthermore, it also includes a pushing mechanism, which is disposed on the side wall of the storage box and above the long straight conveyor belt, and is used to push the sand willow into the wedge-shaped gap formed between the triangular conveyor belt and the long straight conveyor belt.

[0013] Furthermore, the pushing mechanism includes a push plate and a telescopic arm, one end of which is connected to the side wall of the storage box, and the other end of which is connected to the push plate.

[0014] Furthermore, the storage bin has multiple vertically arranged partitions inside.

[0015] Furthermore, each guide rail has a downward-sloping guide block on one side and an upward-sloping guide block on the other side, and the tilting direction of the guide blocks on the same side of the two guide rails is consistent.

[0016] Furthermore, the distance between the fixed-axis pressure roller and the movable pressure roller is matched with the diameter of the willow branch.

[0017] Furthermore, the lever is provided with grooves, and the groove spacing on the lever is the same as the groove spacing on the guide rail.

[0018] Furthermore, the side of the branch insertion mechanism is provided with a trenching mechanism and a soil covering mechanism. The trenching mechanism is located in front of the branch insertion mechanism, and the soil covering mechanism is located behind the branch insertion mechanism. These mechanisms are used to trench before branch insertion and to cover the soil after branch insertion.

[0019] This invention provides a method for laying a one-piece molded sand willow mesh sand barrier, comprising the following steps:

[0020] Bundles of willow branches are placed in a storage bin, and after being evenly divided by the bin's partitions, they fall onto a compression sorting mechanism. Under the conveying of a triangular conveyor belt and a long straight conveyor belt, each willow branch is peeled and conveyed, and then falls into a branch conveying mechanism for further equal-spaced separation. The separated willow branches fall into a feeding hopper, and after two posture corrections by two sets of cross-vertically arranged roller structures, they are squeezed into the trenched sand under the action of the roller structure. Then, the soil covering mechanism covers the inserted positions with soil, completing the insertion. Driven by the reversing mechanism and the driving mechanism, the grid sand barrier is laid.

[0021] Furthermore, by controlling the reversing mechanism and the driving mechanism, the sand barrier laying device is driven to move at a constant speed along the y-axis, and the branch insertion mechanism moves along the x-axis, so that the single row of sand willow branches is laid at a 45° angle along the y-axis laying direction, and a single row of sand barriers is laid; after the single row of sand barriers is laid, the branch insertion mechanism moves along the negative x-direction to realize the laying of the entire grid sand barrier.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention discloses a one-time molding sand willow mesh sand barrier laying device and method, including a storage box, a compression sorting mechanism, a branch conveying mechanism, a branch inserting mechanism, a trenching mechanism, a soil covering mechanism, a tracked chassis, a reversing mechanism, a pushing mechanism, and a driving mechanism. Bundles of sand willow branches can be peeled and conveyed under the action of the compression sorting mechanism. The branch conveying mechanism can separate the sand willow branches at equal intervals. The branch inserting mechanism can correct the posture of the sand willow branches twice, so that the sand willow branches are vertically inserted into the sand. The components used are simpler and more common in structure than robotic arms, which can realize the automated laying of sand willow sand barriers, making them high-quality one-time molding. Compared with grippers, the insertion efficiency is higher. This device can complete the sand willow mesh sand barrier in one go, which has the advantages of standardization and modularity. Moreover, when it is damaged, the technical requirements for repair personnel are not high, and the components used are easy to replace, making it more suitable for remote areas such as Northwest China.

[0032] In the description of this invention, it should be noted that the terms used in the various embodiments, such as "upper," "lower," "front," "rear," "left," and "right," which indicate orientation, are only used to simplify the description of the positional relationships based on the accompanying drawings and do not mean that the components and devices referred to must be operated in accordance with the specific orientations and defined operations, methods, and structures in the specification. Such directional terms do not constitute a limitation of this invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Specific Implementation Plan 1: Combining Figures 1 to 6 As shown, the present invention provides a one-piece molded sand willow mesh sand barrier laying device, including a storage box 1, a compression sorting mechanism 2, a branch conveying mechanism 3, a branch inserting mechanism 4, a trenching mechanism 5, a soil covering mechanism 6, a tracked chassis 7, a reversing mechanism 8, a pushing mechanism 9, and a driving mechanism 10.

[0035] The drive mechanism 10 is used to drive the tracked chassis 7, thereby driving the sand barrier laying device forward or backward. The reversing mechanism 8 is used to control the movement direction of the sand barrier laying device.

[0036] The tracked chassis 7 is equipped with a compression sorting mechanism 2, which is located inside the storage box 1 and at the bottom of the storage box 1. The compression sorting mechanism 2 includes a triangular conveyor belt 201 and a long straight conveyor belt 202 that rotate in opposite directions. The triangular conveyor belt 201 is located above one side of the long straight conveyor belt 202 and the distance between the two matches the diameter of a sand willow tree. A pushing mechanism 9 is provided on the other side of the triangular conveyor belt 201. The pushing mechanism is located on the side wall of the storage box 1 and above the long straight conveyor belt 202. It is used to push the sand willow tree into the wedge-shaped gap formed between the triangular conveyor belt 201 and the long straight conveyor belt 202 through the pushing mechanism 9.

[0037] The storage bin 1 is provided with multiple vertically arranged bin partitions 101 inside, which facilitates uniform material distribution;

[0038] The pushing mechanism 9 includes a push plate and a telescopic arm. One end of the telescopic arm is connected to the side wall of the storage bin 1, and the other end of the telescopic arm is connected to the push plate, which is used to push the willow branches. It should be noted that when there are enough willow branches in the storage bin 1, the push plate does not work. When the sensor detects that there are not enough willow branches in the storage bin 1, the push plate works and pushes the remaining willow branches at the bottom of the storage bin 1 onto the long straight conveyor belt 202 in one go. In addition, the push plate only plays an auxiliary role in the pushing work.

[0039] Below the output ends of the triangular conveyor belt 201 and the long straight conveyor belt 202, a branch conveying mechanism 3 is provided. The branch conveying mechanism 3 includes a base frame, guide rails 301, a branch conveying carriage 302, and a crank rocker arm 303. The base frame is a frame structure, and guide rails 301 are provided on both sides of the base frame. Each guide rail 301 has evenly spaced grooves, and the grooves on the two guide rails 301 correspond one-to-one. Two levers parallel to the guide rails 301 are provided between the two guide rails 301. The levers have grooves on them. The groove spacing is the same as the groove spacing on the guide rail 301. The two ends of the lever are connected to one end of the crank rocker 303, and the other end of the crank rocker 303 is connected to the base frame. During the branch conveying process, the lever is moved upward and backward in a circle by the crank rocker 303, which moves the sand willow branches in the groove on the guide rail 301 to the groove on the lever. Then, the sand willow branches in the groove on the lever are moved to the groove at the top and bottom of the guide rail 301. The sand willow branches located at the edge slide down by the movement of the crank rocker 303 and the lever.

[0040] The guide rail 301 has a downwardly inclined guide block on one side and an upwardly inclined guide block on the other side, which serves to facilitate the slippage of the willow branches and prevent them from slipping.

[0041] Below the output end of the branch conveying mechanism 3, there is a branch insertion mechanism 4. The branch insertion mechanism 4 includes a feeding hopper 401 and two sets of cross-arranged vertical roller structures. Each set of roller structures includes a fixed-axis pressure roller 402 and a movable pressure roller 403. The fixed-axis pressure roller 402 and the movable pressure roller 403 are rotatably connected to the track chassis 7. The distance between the fixed-axis pressure roller 402 and the movable pressure roller 403 matches the diameter of the sand willow branch. During operation, the sand willow branch falls into the feeding hopper 401 and falls vertically or at an angle. The drive motor drives the fixed-axis pressure roller 402 to rotate. The fixed-axis pressure roller 402 indirectly transmits power to the movable pressure roller 403 through the sand willow branch, thereby enabling the two pressure rollers to rotate relative to each other. The two sets of rollers are arranged cross-shaped. When the sand willow branch falls at an angle from the upper feeding hopper 401 into the pressure roller, the sand willow branch is subjected to extrusion pressure as the pressure roller rotates. After two posture corrections by the longitudinal and transverse rollers, the sand willow branch is vertically squeezed into the sand, completing the branch insertion process.

[0042] The side of the branch insertion mechanism 4 is provided with a trenching mechanism 5 and a soil covering mechanism 6. The trenching mechanism 5 is located in front of the branch insertion mechanism 4, and the soil covering mechanism 6 is located behind the branch insertion mechanism 4. It is used to open trenches before branch insertion and to cover soil after branch insertion. Both the trenching mechanism 5 and the soil covering mechanism 6 are commonly used existing devices.

[0043] Specific Implementation Method Two: Combining Figures 1 to 6 As shown, the present invention provides a method for laying a one-piece molded sand willow mesh sand barrier laying device, comprising the following steps:

[0044] Bundles of willow branches are placed in storage bin 1, and after being evenly divided by the bin body partition 101, they fall onto the extrusion sorting mechanism 2. Under the conveying of the push plate, triangular conveyor belt 201 and long straight conveyor belt 202, each willow branch is peeled and conveyed, and then falls into the branch conveying mechanism 3, where it is further divided at equal intervals. The separated willow branches fall into the feeding hopper 401, and after two posture corrections by two sets of cross-vertically arranged roller structures, they are squeezed into the sandy soil after the trench is opened under the action of the roller structure. Then, the soil covering mechanism 6 covers the position after the branches are inserted, completing one insertion.

[0045] The sand barrier laying device is driven to move at a constant speed along the y-axis by controlling the reversing mechanism 8 and the driving mechanism 10. The branching direction of the branching mechanism 4 is along the x-axis. The two directions of movement are perpendicular to each other, thus generating a resultant velocity direction, so that the single row of sand willows is laid at a 45° angle along the y-axis, and the single row of sand barrier is laid. After the single row of sand barrier is laid, the branching mechanism 4 moves along the negative x-direction to realize the laying of the entire grid sand barrier.

[0046] It should be noted that the purpose of manually laying sand barriers in a grid pattern is to block sandstorms from different directions. The effect of this device is to lay sand barriers in a zigzag pattern. Field investigation and research have shown that it can also resist sandstorms from different directions. When laying in the reverse direction, it maintains a distance from the already laid grid and does not form a completely closed grid. Therefore, there will be no sand willow branches at the grid intersections, nor will it damage the sand willow branches at the grid intersections.

[0047] The other combinations and connections in this implementation scheme are the same as in Specific Implementation Scheme 1.

[0048] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
