Description

Technical Field

[0001] The present invention belongs to the technical field of laying Salix psammophila sand barriers, and in particular relates to an automated degradable nylon net sand barrier combined with a mechanical Salix psammophila sand barrier laying machine. Background Art

[0002] Branch sand barriers are an effective measure to prevent wind and fix sand. They block wind and sand by setting obstacles composed of plant branches (such as willow branches) on the surface of the sand dunes. However, the existing willow sand barrier settings mainly rely on manually inserting purchased willow branches of the same size into the sand one by one. This method is labor-intensive and inefficient, and requires a lot of manpower and time in large-scale sand prevention and control projects. Moreover, the depth and angle of manual insertion are difficult to ensure high consistency, which may affect the overall stability of the sand barrier and the sand fixation effect. At the same time, if only willow branches are inserted into the sand, under the continuous action of strong winds, local willow branches are prone to tilting and falling, resulting in the destruction of the sand barrier structure. With long-term use, the sand fixation ability will be greatly reduced. Moreover, when a single willow sand barrier blocks wind and sand, the wind and sand can easily bypass the willow branches and continue to move forward, and strong wind and sand activities will still form behind the sand barrier. Summary of the Invention

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1 like Figures 1-14As shown, an automated degradable nylon mesh sand barrier combined with a mechanical tamarisk sand barrier laying machine includes a vehicle body 1. The front end of the vehicle body 1 is connected to an external drive device (not shown in the figure), and the vehicle body 1 is driven to move by the external drive device. A plurality of partition walls 3 are provided on one side of the vehicle body 1. A placement groove 301 for placing the tamarisk strip finished product 2 is formed between two adjacent partition walls 3. A pushing structure is provided on one side of the placement groove 301, specifically: Figure 13 and Figure 14 As shown, the pushing structure includes a base 8 mounted on the vehicle body 1, one side of the base 8 is rotatably connected to a pushing screw 81, a third motor 82 is mounted on one side of the base 8, and the output shaft of the third motor 82 is fixedly connected to the free end of the pushing screw 81, the inner wall of the base 8 is slidably connected to a pushing plate 83, the pushing plate 83 is threadedly engaged with the pushing screw 81, and one side of the pushing plate 83 is fixedly connected to a plurality of umbrella-type pushing rods 84 corresponding to the placement grooves 301, and the side of the umbrella-type pushing rods 84 away from the pushing plate 83 is located in the corresponding placement groove 301; Further, such as Figure 5 As shown, the bottoms of the multiple partition walls 3 are fixedly connected to the same bottom plate 31. The staff places the purchased tamarisk strips 2 of the same size in the placement groove 301. The bottom plate 31 is provided to close the bottom of the guide groove 302 and support the bottom of the tamarisk strips 2. The bottom plate 31 is provided with a plurality of discharge openings 3101 corresponding to the placement grooves 301 on the side away from the pushing structure. The discharge openings 3101 are used to discharge the tamarisk strips 2 located in the placement grooves 301 one by one. The side of the two adjacent partition walls 3 that are close to each other is provided with side blocks 303 corresponding to the discharge openings 3101. The side blocks 303 provided can limit the tamarisk strips 2. Specifically, the third motor 82 drives the pushing screw 81 to rotate through its output shaft, and under the action of the threaded engagement, the pushing plate 83 moves in the direction close to the partition wall 3. At the same time, the pushing plate 83 drives the umbrella-type pushing rod 84 to move in the same direction, thereby pushing the finished tamarisk strip 2 located in the placement groove 301.

[0023] like Figure 4-Figure 7 As shown, an avoidance type downward pressure structure is provided on the other side of the placement groove 301, and a guide groove 302 is symmetrically opened between two adjacent partition walls 3. The guide groove 302 is divided into an avoidance area 3021, a contraction area 3022 and a downward pressure area 3023 from top to bottom; The avoidance pressing structure includes a pressing screw 4 and a plurality of pressing pieces corresponding to the guide grooves 302, a gap for the pressing piece to pass through is left between the two side blocks 303, the pressing screw 4 is threadedly engaged with a push plate 41, the pressing piece is composed of two pressing heads 42, and the pressing heads 42 are slidably inserted on the push plate 41, the two pressing heads 42 are in rolling contact with the groove surfaces of the corresponding guide grooves 302 through rollers 43, and a spring 44 is provided between the two pressing heads 42. Specifically, an inner groove 4201 is provided on the side where the two pressing heads 42 on the same pressing piece are close to each other, and the two inner grooves 4201 are slidably connected with at least two spring limiting rods 45, the spring 44 is sleeved on the spring limiting rod 45, and the spring limiting rod 45 provided can ensure that the spring 44 will not deviate or twist outward when contracting or stretching, wherein the spring 44 is in a compressed state to ensure that the roller 43 keeps in contact with the groove surface of the guide groove 302; like Figure 6 As shown, the side walls of the contraction area 3022 and the lower pressing area 3023 are provided with avoidance grooves 304 corresponding to the spring limiting rod 45, ensuring that the spring limiting rod 45 does not interfere with the side walls of the contraction area 3022 and the lower pressing area 3023 when the pressure head 42 moves; The rollers 43 are rotatably connected to the sides of the two pressing heads 42 that are away from each other. The rollers 43 are in rolling contact with the groove surfaces of the corresponding guide grooves 302 .

[0024] Furthermore, the avoidance-type downward pressure structure further includes a first motor 46, a top plate 47 and a bottom support plate 48. The tops of the multiple partition walls 3 are detachably fixed with the same top plate 47, and the top plate 47 is used to support the first motor 46. like Figure 4 and Figure 5 As shown, when the bottom support plate 48 is installed, an inner alignment groove 305 is opened at the bottom of each partition wall 3, and an inserting plate 481 corresponding to the inner alignment groove 305 is provided on one side of the bottom support plate 48, and the inserting plate 481 is detachably fixed in the corresponding inner alignment groove 305. The inner alignment groove 305 allows the bottom support plate 48 to be fixed to the partition wall 3 while allowing the inserting plate 481 to be hidden in the inner alignment groove 305, thereby avoiding interference between the push plate 41 and the inserting plate 481 when the push plate 41 moves; The bottom support plate 48 is provided with a through hole for the pressing piece to pass through, ensuring that the pressing piece can smoothly press out the finished sand willow strips 2; The two ends of the pressing screw 4 are rotatably connected to the top plate 47 and the bottom support plate 48 respectively. The first motor 46 is installed on the top of the top plate 47, and the output shaft of the first motor 46 is fixedly connected to the pressing screw 4. Two limiting slide bars 49 are symmetrically fixed to the bottom of the top plate 47. The bottoms of the two limiting slide bars 49 are fixed to the top of the bottom support plate 48. The two sides of the push plate 41 are slidably connected to the limiting slide bars 49. The limiting slide bars 49 can limit the push plate 41 to prevent the push plate 41 from rotating with the pressing screw 4. Specifically, when working, the finished tamarisk strips 2 located in the placement groove 301 are pushed a distance by the umbrella-type pushing rod 84. At this time, the finished tamarisk strips 2 at the edge will move to the discharge port 3101. The first motor 46 drives the pressing screw 4 to rotate through its output shaft, and the push plate 41 moves downward under the action of the thread engagement. During the downward movement, the pressure head 42 and the roller 43 will pass through the avoidance area 3021, the contraction area 3022 and the downward pressure area 3023 in turn. When passing through the contraction area 3022, the two rollers 43 move. At the same time, it will also drive the pressure head 42 to move inward. When moving inward, the spring 44 between the two pressure heads 42 will be further compressed. When reaching the lower pressure area 3023, the two pressure heads 42 will merge together, and the bottom of the two pressure heads 42 will be located above the finished tamarisk strips 2 at the outlet 3101. As the two pressure heads 42 move downward along the lower pressure area 3023, the corresponding finished tamarisk strips 2 will be pressed out of the placement groove 301 and the bottom of the finished tamarisk strips 2 will be inserted into the sandy soil. The planting efficiency is high and there is no need to manually dig planting grooves.

[0025] Further, such as Figure 1 As shown, a protective cover 410 is detachably mounted on the vehicle body 1, the inner walls on both sides of the protective cover 410 are engaged with the two partition walls 3 located at the edges, and the first motor 46, the top plate 47 and the bottom support plate 48 are located in the inner cavity of the protective cover 410. The first motor 46, the top plate 47 and the bottom support plate 48 can be protected by the provided protective cover 410.

[0026] Example 2 like Figures 1-14 As shown, this embodiment has made the following improvements on the basis of the first embodiment: Figure 1 and Figure 2 As shown, the automated degradable nylon net sand barrier combined with mechanical Salix psammophila sand barrier laying machine further includes a spiral turning tube 5 fixedly connected to the bottom of the vehicle body 1, one end of the spiral turning tube 5 is horizontal and the other end is vertical, and a nylon net 61 is placed on the vehicle body 1. Specifically, a storage tank 101 for storing the nylon net 61 is provided on the vehicle body 1, and a support rod 6 is rotatably connected to the storage tank 101, and the nylon net 61 is wound on the support rod 6; The automated degradable nylon net sand barrier combined with the mechanical willow sand barrier laying machine also includes a reciprocating net structure, such as Figure 10-13As shown, the reciprocating mesh structure includes a protection frame 7, two driven gear discs 71 are installed in the protection frame 7, and an eccentric shaft 72 is provided on one side of the driven gear disc 71, and two T-shaped slide bars 73 corresponding to the eccentric shaft 72 are installed on the protection frame 7, and the T-shaped slide bar 73 is provided with a slide groove 7301, and the eccentric shaft 72 is slidably connected in the corresponding slide groove 7301. Specifically, the protection frame 7 is U-shaped and is installed at the bottom of the base plate 31, and a buckle 711 is provided on one side of the driven gear disc 71, and the driven gear disc 71 is rotatably connected to the inner wall of the protection frame 7 through the buckle 711, so as to facilitate the later disassembly of the work staff, and the horizontal end of the T-shaped slide bar 73 is symmetrically provided with a positioning slide groove 7302, and a slider 74 corresponding to the positioning slide groove 7302 is provided on the protection frame 7, and the slider 74 is slidably inserted into the corresponding positioning slide groove 7302; The horizontal end of the T-shaped slide bar 73 passes through the protection frame 7, and the end is provided with a clamping net assembly, specifically: the clamping net assembly includes a roller bracket 79 and a roller 710. The side of one end of the T-shaped slide bar 73 extending out of the protection frame 7 is fixedly connected to an L-shaped connecting rod 78. The same roller bracket 79 is detachably installed between the connecting rod 78 and the T-shaped slide bar 73. Two rollers 710 are symmetrically connected to the roller bracket 79 for rotation. The rollers 710 are hollow inside, thereby reducing the weight of the rollers 710 themselves. A gap is left between the two rollers 710 for the nylon net 61 to pass through; the provided rollers 710 can reduce the friction with the nylon net 61, thereby preventing the nylon net 61 from being damaged; Among them, two roller brackets 79 are located on the sides of the two partition walls 3 at the extreme edges; The free end of the nylon mesh 61 passes through the spiral deflection tube 5 and the mesh assembly in sequence. Specifically, the free end of the nylon mesh 61 enters from the horizontal end of the spiral deflection tube 5, exits from the vertical end, and passes through the gap between the two rollers 710 in sequence. A rotating shaft 75 is rotatably connected inside the protective frame 7. Two driving gears 76 corresponding to the driven gear discs 71 are symmetrically fixed to the rotating shaft 75. The driving gears 76 are engaged with the corresponding driven gear discs 71. A second motor 77 is installed on one side of the protective frame 7, and the output shaft of the second motor 77 is fixed to the rotating shaft 75.

[0027] Specifically: After the bottom of the finished sand willow strips 2 is inserted into the sandy ground for the first time, the second motor 77 drives the rotating shaft 75 and the driving gear 76 fixed to the rotating shaft 75 to rotate 180 degrees through its output shaft. Under the meshing action, the driving gear 76 drives the corresponding driven gear plate 71 to rotate 180 degrees. During the rotation of the driven gear plate 71, the eccentric shaft 72 rotates in the direction close to the slider 74. At this time, the eccentric shaft 72 pushes the T-shaped slide bar 73 to extend the horizontal end of the T-shaped slide bar 73, thereby attaching the nylon net 61 to the side of the group of finished sand willow strips 2 close to the vehicle body 1; Then, after the staff fixes the free end of the nylon mesh 61 to the finished product 2 of the sand willow strips, the external driving device is used to drive the vehicle body 1 to move forward a distance. At the same time, the first motor 46 drives the pressing screw 4 to rotate in the opposite direction and reset through its output shaft. Under the action of the thread engagement, the push plate 41 moves upward and resets. During the upward movement, the pressure head 42 and the roller 43 will pass through the pressing area 3023, the contraction area 3022 and the avoidance area 3021 in sequence. At this time, when passing through the contraction area 3022, the compressed spring 44 will push the pressure head 42, so that the two rollers 43 will expand to both sides along the groove surface of the contraction area 3022. When reaching the avoidance area 3021, the two pressure heads 42 will move to the corresponding guide groove 302. After resetting, the vehicle body 1 stops moving forward, and at this time the finished tamarisk strips 2 located in the placement groove 301 is pushed a certain distance further by the umbrella-type pushing rod 84, wherein the avoidance area 3021 is set to make the pressure head 42 hidden in the avoidance area 3021, so as to avoid the tamarisk strips 2 from colliding with the pressure head 42 when being pushed; then, under the action of the avoidance-type downward pressure structure, the finished tamarisk strips 2 located at the discharge port 3101 is pressed out again and the bottom of the finished tamarisk strips 2 is inserted into the sandy soil, and the bottom of the group of finished tamarisk strips 2 is inserted into the sandy soil. After the ground is hit, the second motor 77 drives the rotating shaft 75 and the driving gear 76 fixed to the rotating shaft 75 to rotate 180 degrees again through its output shaft. Under the meshing action, the driving gear 76 drives the corresponding driven gear plate 71 to rotate 180 degrees. At this time, during the rotation of the driven gear plate 71, the eccentric shaft 72 rotates in the direction away from the slider 74. At this time, the eccentric shaft 72 pulls the T-shaped slide bar 73 to retract the horizontal end of the T-shaped slide bar 73 to return to its original position, so that the nylon net 61 will be attached to the side of the group of sand willow strips 2 away from the vehicle body 1; According to the above steps, the nylon net 61 is continuously cycled and attached to the tamarisk finished product 2 in an S shape. By attaching the nylon net 61 in an S shape to the tamarisk finished product 2, the overall stability of the tamarisk finished product 2 is improved, and the partial collapse of the tamarisk finished product 2 is avoided. At the same time, the nylon net 61 can also seal the gap between two adjacent tamarisk finished products 2. When the wind and sand pass through the sand barrier, the mesh of the nylon net 61 can disperse and weaken the impact of the wind and sand on the tamarisk finished product 2, thereby reducing the flow rate of the wind and sand, reducing wind erosion of the soil, and leveling and managing the sandy land.

[0028] The nylon mesh 61 is made of a degradable material so that the nylon mesh 61 can be naturally degraded in the later stage, thereby avoiding a large amount of nylon mesh 61 remaining on the sandy land and causing additional pollution to the environment. Among them, when the pressure head 42 moves to the bottom of the lower pressure area 3023, the bottom of the T-shaped slide bar 73 and the connecting rod 78 are higher than the bottom of the pressure head 42, ensuring that after the tamarisk finished product 2 is inserted into the sandy soil, the top of the tamarisk finished product 2 will not interfere with the T-shaped slide bar 73 and the connecting rod 78 when the vehicle body 1 moves forward.

[0029] Example 3 like Figures 1-14 As shown, this embodiment has made the following improvements on the basis of the second embodiment: Figure 1 As shown, a storage box 9 for storing the finished tamarisk strips 2 is also installed on the vehicle body 1. As the umbrella-type pushing rod 84 pushes the finished tamarisk strips 2, when it is necessary to replenish the finished tamarisk strips 2 into the placement slot 301, the third motor 82 drives the pushing screw 81 to rotate in the opposite direction through its output shaft, and under the action of the threaded engagement, the pushing plate 83 is moved and reset in the direction away from the partition wall 3, so that the pushing plate 83 drives the umbrella-type pushing rod 84 to move and reset, so that the staff can add the finished tamarisk strips 2.

[0030] In summary, the workflow of the present invention is as follows: When the finished tamarisk strips 2 are inserted for the first time, the third motor 82 drives the pushing screw 81 to rotate through its output shaft, and the pushing plate 83 moves in the direction close to the partition wall 3 under the action of the thread engagement. At the same time, the pushing plate 83 drives the umbrella-type pushing rod 84 to move in the same direction, thereby pushing the finished tamarisk strips 2 located in the placement groove 301 for one end distance. At this time, the finished tamarisk strips 2 at the edge will move to the discharge port 3101, and the first motor 46 drives the pressing screw 4 to rotate through its output shaft, and the pushing plate 41 moves downward under the action of the thread engagement. During the downward movement, the pressure head 42 and the roller 43 will pass through the groove 301 in turn. After passing through the avoidance area 3021, the contraction area 3022 and the downward pressure area 3023, when passing through the contraction area 3022, the two rollers 43 will also drive the pressure heads 42 to move inward while moving. When moving inward, the spring 44 between the two pressure heads 42 will be further compressed. When reaching the downward pressure area 3023, the two pressure heads 42 will merge together, and the bottoms of the two pressure heads 42 will be located above the finished tamarisk strips 2 at the discharge port 3101. As the two pressure heads 42 move downward along the downward pressure area 3023, the corresponding finished tamarisk strips 2 will be pressed out of the placement groove 301 and the bottoms of the finished tamarisk strips 2 will be inserted into the sandy soil. After the bottom of the group of finished sand willow strips 2 is inserted into the sandy ground, the second motor 77 drives the rotating shaft 75 and the driving gear 76 fixed to the rotating shaft 75 to rotate 180 degrees through its output shaft. Under the meshing action, the driving gear 76 drives the corresponding driven gear plate 71 to rotate 180 degrees. During the rotation of the driven gear plate 71, the eccentric shaft 72 rotates in the direction close to the slider 74. At this time, the eccentric shaft 72 pushes the T-shaped slide bar 73 to extend the horizontal end of the T-shaped slide bar 73, thereby attaching the nylon net 61 to the side of the group of finished sand willow strips 2 close to the vehicle body 1; Then, after the staff fixes the free end of the nylon mesh 61 to the finished product 2 of the sand willow strips, the external driving device is used to drive the vehicle body 1 to continue moving forward for a distance. At the same time, the first motor 46 drives the pressing screw 4 to rotate in the opposite direction and reset through its output shaft. Under the action of the thread engagement, the push plate 41 moves upward and resets. During the upward movement, the pressure head 42 and the roller 43 will pass through the pressing area 3023, the contraction area 3022 and the avoidance area 3021 in sequence. At this time, when passing through the contraction area 3022, the compressed spring 44 will push the pressure head 42, so that the two rollers 43 will expand to both sides along the groove surface of the contraction area 3022. When reaching the avoidance area 3021, the two pressure heads 42 will move to the corresponding guide groove 302. After resetting, the vehicle body 1 stops moving forward. At this time, the finished tamarisk strip 2 located in the placement groove 301 is pushed a distance further by the umbrella-type pushing rod 84, and then the finished tamarisk strip 2 located at the discharge port 3101 is pressed out again under the action of the avoidance-type downward pressure structure, and the bottom of the finished tamarisk strip 2 is inserted into the sandy ground. After the bottom of the group of finished tamarisk strips 2 is inserted into the sandy ground, the second motor 77 drives the rotating shaft 75 and the driving gear 76 fixed to the rotating shaft 75 to rotate 180° again through its output shaft. Under the meshing action, the driving gear 76 drives the corresponding driven gear plate 71 to rotate 180°. At this time, during the rotation of the driven gear plate 71, the eccentric shaft 72 will rotate in the direction away from the slider 74. At this time, the eccentric shaft 72 will pull the T-shaped slide bar 73 to retract the horizontal end of the T-shaped slide bar 73 to return to its original position, so that the nylon net 61 will be attached to the side of the group of finished tamarisk strips 2 away from the vehicle body 1; The above steps are continuously circulated so that the nylon mesh 61 is attached to the finished tamarisk strips 2 in an S shape.
