Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sand barrier laying of Salix mongolica, and particularly relates to an automatic degradable nylon net sand barrier combined with a mechanical Salix mongolica sand barrier laying machine. BACKGROUND

[0002] The branch sand barrier is an effective wind prevention and sand fixation measure, which blocks the wind and sand by setting an obstacle composed of plant branches (for example, willow branches) on the surface of a sand dune. However, the existing willow branch sand barrier setting mainly relies on manually inserting the purchased willow branch products of the same size into the sandy soil one by one. This way has high labor intensity and low efficiency, and a large amount of manpower and time needs to be invested in large-scale sand prevention and control projects. In addition, the depth and angle of manual insertion are difficult to guarantee high consistency, which may affect the stability and sand fixation effect of the sand barrier as a whole. Meanwhile, if the willow branches are only inserted into the sandy soil, the local willow branches are prone to tilting and falling under the continuous action of strong wind, which may cause the structure of the sand barrier to be damaged. In addition, the wind and sand are easy to bypass the willow branches and continue to move forward, which may form strong wind and sand activities behind the sand barrier. SUMMARY

DETAILED DESCRIPTION

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example 1

[0055] like Figures 1-14 As shown, an automated biodegradable nylon mesh sand barrier combined with a mechanical willow 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), which drives the vehicle body 1 to move. Multiple partition walls 3 are provided on one side of the vehicle body 1. A placement groove 301 for placing finished willow branches 2 is formed between two adjacent partition walls 3. A pushing structure is provided on one side of the placement groove 301, specifically as follows: Figure 13 and Figure 14 As shown, the pushing structure includes a base 8 mounted on the vehicle body 1. A push screw 81 is rotatably connected to one side of the base 8. 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 push screw 81. A push plate 83 is slidably connected to the inner wall of the base 8. The push plate 83 is threadedly engaged with the push screw 81. A plurality of umbrella-shaped push rods 84 corresponding one-to-one with the placement slots 301 are fixedly connected to one side of the push plate 83. The side of the umbrella-shaped push rod 84 away from the push plate 83 is located in the corresponding placement slot 301.

[0056] Furthermore, such as Figure 5 As shown, the bottom of multiple partition walls 3 is fixed with the same base plate 31. The staff places the purchased willow branches 2 of the same size into the placement groove 301. The base plate 31 can close the bottom of the guide groove 302 and support the bottom of the willow branch 2. The side of the base plate 31 away from the pushing structure is provided with multiple outlets 3101 corresponding to the placement groove 301. The outlets 3101 are used to discharge the willow branch 2 in the placement groove 301 one by one. The side of two adjacent partition walls 3 that are close to each other is provided with side blocks 303 corresponding to the outlets 3101. The side blocks 303 can limit the willow branch 2.

[0057] Specifically, the third motor 82 drives the push screw 81 to rotate through its output shaft. Under the action of thread engagement, the push plate 83 moves along the direction close to the partition wall 3. At the same time, the push plate 83 drives the umbrella-shaped push rod 84 to move in the same direction, thereby pushing the finished sand willow branch 2 located in the placement groove 301.

[0058] like Figures 4-7As shown, the other side of the placing groove 301 is provided with an avoiding type pressing structure, and the guide grooves 302 are symmetrically arranged between the adjacent two partition walls 3;

[0059] The avoiding type pressing structure comprises a pressing screw 4 and a plurality of pressing pieces corresponding to the guide grooves 302. The gap between the two side blocks 303 is used for the pressing pieces to pass through. 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 slidingly inserted on the push plate 41. The two pressing heads 42 are in rolling contact with the corresponding guide groove 302 through a roller 43. The two pressing heads 42 are provided with a spring 44. Specifically, the side close to the two pressing heads 42 on the same pressing piece is provided with an inner groove 4201, and the two inner grooves 4201 are jointly connected with at least two spring limiting rods 45. The spring 44 is sleeved on the spring limiting rod 45. The spring limiting rod 45 can ensure that the spring 44 does not deviate outward or twist when it is contracted or stretched. The spring 44 is in a compressed state, which ensures that the roller 43 is in contact with the groove surface of the guide groove 302.

[0060] As shown in Figure 6 , the side walls of the contraction area 3022 and the pressing area 3023 are provided with avoiding grooves 304 corresponding to the spring limiting rods 45, which ensures that the spring limiting rods 45 interfere with the side walls of the contraction area 3022 and the pressing area 3023 when the pressing heads 42 move.

[0061] The side away from the two pressing heads 42 is rotatably connected with the roller 43, which is in rolling contact with the corresponding guide groove 302.

[0062] Further, the avoiding type pressing structure further comprises a first motor 46, a top plate 47 and a bottom support plate 48. The top of the plurality of partition walls 3 is detachably connected with the same top plate 47. The top plate 47 is used to support the first motor 46.

[0063] As shown in Figure 4 and Figure 5 , when the bottom support plate 48 is installed, the bottom of each partition wall 3 is provided with an inner positioning groove 305. One side of the bottom support plate 48 is provided with an insertion plate 481 corresponding to the inner positioning groove 305, and the insertion plate 481 is detachably connected in the corresponding inner positioning groove 305. The inner positioning groove 305 can make the bottom support plate 48 and the insertion plate 481 hidden in the inner positioning groove 305 when they are connected, so as to avoid interference between the push plate 41 and the insertion plate 481 when the push plate 41 moves.

[0064] The bottom support plate 48 is provided with a through hole for the pressing piece to pass through, so that the pressing piece can smoothly press out the sand willow strip product 2.

[0065] The two ends of the pressing screw rod 4 are rotationally connected with the top plate 47 and the bottom support plate 48 respectively, and 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 with the pressing screw rod 4;

[0066] The bottom of the top plate 47 is symmetrically fixedly connected with two limiting slide rods 49, the bottoms of the two limiting slide rods 49 are fixedly connected with the top of the bottom support plate 48, and the two sides of the push plate 41 are slidingly connected with the limiting slide rods 49. The limiting slide rods 49 can limit the push plate 41, so that the push plate 41 is prevented from rotating with the pressing screw rod 4.

[0067] Specifically, during work, the umbrella-shaped pushing rod 84 pushes the sand-willow strip product 2 in the placing groove 301 by a distance, at this time, the sand-willow strip product 2 at the edge moves to the discharge port 3101, the first motor 46 drives the pressing screw rod 4 to rotate through the output shaft, and the push plate 41 moves downward under the action of thread engagement. During the downward movement, the pressing heads 42 and the rollers 43 pass through the avoiding area 3021, the contraction area 3022 and the pressing area 3023 in sequence. When passing through the contraction area 3022, the two rollers 43 also drive the pressing heads 42 to move inward while moving, and the springs 44 between the two pressing heads 42 are further compressed when moving inward. When reaching the pressing area 3023, the two pressing heads 42 are combined together, and the bottoms of the two pressing heads 42 are located above the sand-willow strip product 2 at the discharge port 3101. With the movement of the two pressing heads 42 along the pressing area 3023, the corresponding sand-willow strip product 2 is pressed out of the placing groove 301 and the bottom of the sand-willow strip product 2 is inserted into the sandy soil, so that the planting efficiency is high and manual planting of the planting groove is not needed.

[0068] Further, as shown in Figure 1 , the vehicle body 1 is detachably provided with a protective cover plate 410, the two side inner walls of the protective cover plate 410 are clamped with the two partition walls 3 at the edge, 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 plate 410. The protective cover plate 410 can protect the first motor 46, the top plate 47 and the bottom support plate 48.

[0069] Embodiment Two

[0070] As shown in Figures 1-14 , the embodiment is improved on the basis of the first embodiment: as shown in Figure 1 and Figure 2 , the automatic degradable nylon net sand barrier combined with the mechanical sand-willow sand barrier laying machine further comprises a spiral variable-direction pipe 5 fixedly connected to the bottom of the vehicle body 1, one end of the spiral variable-direction pipe 5 is horizontally arranged, and the other end is vertically arranged. The vehicle body 1 is provided with a storage groove 101 for storing the nylon net 61, and the storage groove 101 is rotationally connected with a support rod 6, and the nylon net 61 is wound on the support rod 6.

[0071] The automatic degradable nylon net sand barrier combined with the mechanical willow sand barrier laying machine further comprises a reciprocating net laying structure, like Figures 10-13 As shown in the drawings, the reciprocating net laying structure comprises a protection frame 7, two driven tooth plates 71 are installed in the protection frame 7, an eccentric shaft 72 is arranged on one side of the driven tooth plate 71, two T-shaped slide rods 73 corresponding to the eccentric shaft 72 are installed on the protection frame 7, the T-shaped slide rod 73 is provided with a sliding groove 7301, the eccentric shaft 72 is slidably connected in the corresponding sliding groove 7301, specifically, the protection frame 7 is U-shaped and is installed at the bottom of the bottom plate 31, the driven tooth plate 71 is provided with a buckle 711 on one side, and the driven tooth plate 71 is rotatably connected to the inner wall of the protection frame 7 through the buckle 711, so as to facilitate the disassembly of the working staff in the later stage, the horizontal end of the T-shaped slide rod 73 is symmetrically provided with a positioning sliding groove 7302, the protection frame 7 is provided with a sliding block 74 corresponding to the positioning sliding groove 7302, and the sliding block 74 is slidably inserted into the corresponding positioning sliding groove 7302;

[0072] The horizontal end of the T-shaped slide rod 73 penetrates the protection frame 7, and the end is provided with a net clamping assembly, specifically, the net clamping assembly comprises a roller shaft support 79 and a rotating roller 710, one end of the T-shaped slide rod 73 extending out of the protection frame 7 is fixedly connected with an L-shaped connecting rod 78, the same roller shaft support 79 is detachably installed between the connecting rod 78 and the T-shaped slide rod 73, two rotating rollers 710 are symmetrically rotatably connected to the roller shaft support 79, the rotating roller 710 is hollow, thereby reducing the weight of the rotating roller 710 itself, and gaps are left between the two rotating rollers 710 for the nylon net 61 to pass through; the rotating roller 710 arranged can reduce the friction with the nylon net 61, and avoid damaging the nylon net 61;

[0073] Among them, the two roller shaft supports 79 are located at the side of the two partition walls 3 at the edge;

[0074] The free end of the nylon net 61 sequentially passes through the spiral direction-changing pipe 5 and the net clamping assembly; specifically, the free end of the nylon net 61 passes in from the horizontal end of the spiral direction-changing pipe 5, passes out from the vertical end, and sequentially passes through the gaps left between the two rotating rollers 710;

[0075] A rotating shaft 75 is rotatably connected in the protection frame 7, two driving gears 76 corresponding to the driven tooth plate 71 are fixedly connected to the rotating shaft 75 in a symmetrical manner, the driving gear 76 is engaged with the corresponding driven tooth plate 71, and a second motor 77 is installed on one side of the protection frame 7, and the output shaft of the second motor 77 is fixedly connected with the rotating shaft 75.

[0076] Specifically: after the bottom of the first set of sand willow products 2 is inserted into the sandy soil, at this time the second motor 77 drives the rotating shaft 75 and the driving gear 76 fixed on the rotating shaft 75 to rotate 180° through the output shaft, under the meshing effect, the driving gear 76 drives the corresponding driven gear plate 71 to rotate 180°, in the rotating process of the driven gear plate 71, the eccentric shaft 72 will rotate along the direction close to the sliding block 74, at this time the eccentric shaft 72 will push the T-shaped slide rod 73 to make the horizontal end of the T-shaped slide rod 73 extend, so that the nylon net 61 is attached to the side of the first set of sand willow products 2 close to the vehicle body 1;

[0077] Then the staff fixes the free end of the nylon net 61 with the sand willow products 2, and drives the vehicle body 1 to move forward a distance through the external driving device, at the same time, the first motor 46 drives the downward pressing screw 4 to rotate reversely and reset through the output shaft, under the effect of thread engagement, the push plate 41 moves upward and resets, in the upward moving process, the pressure head 42 and the roller 43 will pass through the downward pressing area 3023, the contraction area 3022 and the avoiding area 3021 in turn, at this time, when passing through the contraction area 3022, the spring 44 in the compressed state will push the pressure head 42, so that the two rollers 43 expand along the groove surface of the contraction area 3022 to both sides, when reaching the avoiding area 3021, at this time, the two pressure heads 42 will move into the corresponding guide groove 302;

[0078] After resetting, the vehicle body 1 stops moving forward, at this time, the sand willow products 2 located in the placing groove 301 are pushed again through the umbrella type pushing rod 84, wherein, the avoiding area 3021 can make the pressure head 42 hidden in the avoiding area 3021, so as to avoid the conflict between the sand willow products 2 and the pressure head 42 when the sand willow products 2 are pushed; then the sand willow products 2 located at the discharge port 3101 are pressed out again under the action of the avoiding type downward pressing structure, and the bottom of the sand willow products 2 is inserted into the sandy soil, after the bottom of the first set of sand willow products 2 is inserted into the sandy soil, at this time the second motor 77 drives the rotating shaft 75 and the driving gear 76 fixed on the rotating shaft 75 to rotate 180° again through the output shaft, under the meshing effect, the driving gear 76 drives the corresponding driven gear plate 71 to rotate 180°, at this time, in the rotating process of the driven gear plate 71, the eccentric shaft 72 will rotate away from the sliding block 74, at this time the eccentric shaft 72 will pull the T-shaped slide rod 73 to make the horizontal end of the T-shaped slide rod 73 retract and reset, so that the nylon net 61 will be attached to the side of the first set of sand willow products 2 away from the vehicle body 1;

[0079] By continuously repeating the above steps, the nylon mesh 61 is attached to the finished sand willow branch 2 in an S-shape. By attaching the nylon mesh 61 to the finished sand willow branch 2 in an S-shape, the overall stability of the finished sand willow branch 2 is improved, and local collapse of the finished sand willow branch 2 is prevented. At the same time, the nylon mesh 61 can also seal the gaps between two adjacent finished sand willow branch 2. When wind and sand pass through the sand barrier, the mesh of the nylon mesh 61 can disperse and weaken the impact of wind and sand on the finished sand willow branch 2, thereby reducing the flow velocity of wind and sand, reducing wind erosion of the soil, and improving the condition and management of sandy land.

[0080] Among them, the nylon mesh 61 is made of biodegradable material so that the nylon mesh 61 can be naturally degraded in the later stage, avoiding the large amount of nylon mesh 61 left on the sandy soil and causing additional pollution to the environment;

[0081] When the pressure head 42 moves to the bottom of the pressure zone 3023, the bottom of the T-shaped slide bar 73 and the connecting rod 78 is higher than the bottom of the pressure head 42, ensuring that after the sand willow branch product 2 is inserted into the sandy soil, the top of the sand willow branch product 2 will not interfere with the T-shaped slide bar 73 and the connecting rod 78 when the vehicle body 1 moves forward.

[0083] like Figures 1-14 As shown, this embodiment is an improvement on embodiment two as follows: Figure 1 As shown, the vehicle body 1 is also equipped with a storage box 9 for storing the finished sand willow branch 2. As the umbrella-type push rod 84 pushes the finished sand willow branch 2, when it is necessary to add the finished sand willow branch 2 to the placement slot 301, the third motor 82 drives the push screw 81 to rotate in the opposite direction through its output shaft. Under the action of thread engagement, the push plate 83 moves and resets in the direction away from the partition wall 3, thereby causing the push plate 83 to drive the umbrella-type push rod 84 to move and reset, so that the staff can add the finished sand willow branch 2.

[0084] In summary, the workflow of this invention is as follows:

[0085] When the first Salix strip product 2 is inserted, the third motor 82 rotates the push screw 81 through its output shaft, and under the action of thread engagement, the push plate 83 moves along the direction close to the partition wall 3, and at the same time, the umbrella-shaped push rod 84 moves in the same direction, thereby pushing the Salix strip product 2 in the placement groove 301 by a distance. At this time, the Salix strip product 2 at the edge moves to the discharge port 3101, and the first motor 46 rotates the downward push screw 4 through its output shaft, and under the action of thread engagement, the push plate 41 moves downward. 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 pressing area 3023 in turn. When passing through the contraction area 3022, the two rollers 43 will also drive the pressure head 42 to move inward while moving, and the spring 44 between the two pressure heads 42 will be further compressed when moving inward. When reaching the downward pressing area 3023, the two pressure heads 42 are combined together, and the bottoms of the two pressure heads 42 are located above the Salix strip product 2 at the discharge port 3101. With the downward movement of the two pressure heads 42 along the downward pressing area 3023, the corresponding Salix strip product 2 is pressed out of the placement groove 301, and the bottom of the Salix strip product 2 is inserted into the sandy soil;

[0086] After the bottoms of the group of Salix strip products 2 are inserted into the sandy soil, the second motor 77 rotates the rotating shaft 75 and the driving gear 76 fixed on the rotating shaft 75 through its output shaft by 180°, and under the action of meshing, the driving gear 76 drives the corresponding driven gear disc 71 to rotate by 180°. During the rotation of the driven gear disc 71, the eccentric shaft 72 will rotate along the direction close to the sliding block 74, and at this time, the eccentric shaft 72 will push the T-shaped sliding rod 73 to make the horizontal end of the T-shaped sliding rod 73 extend, so as to attach the nylon net 61 to the side of the group of Salix strip products 2 close to the vehicle body 1;

[0087] Then, after the staff fixes the free end of the nylon net 61 to the Salix strip product 2, the vehicle body 1 is driven by the external driving device to move forward by a distance, and at the same time, the first motor 46 drives the downward push screw 4 to rotate reversely through its output shaft, and under the action of thread engagement, the push plate 41 moves upward to reset. During the upward movement, the pressure head 42 and the roller 43 will pass through the downward pressing area 3023, the contraction area 3022 and the avoidance area 3021 in turn. At this time, when passing through the contraction area 3022, the spring 44 in the compressed state will push the pressure head 42, so as to make the two rollers 43 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 into the corresponding guide groove 302 at this time;

[0088] After reset, the vehicle body 1 stops moving forward, at this time, the sand willow strip products 2 located in the placing groove 301 are pushed by the umbrella type pushing rod 84 for a distance, and then the sand willow strip products 2 located at the discharge port 3101 are pressed out again under the action of the avoidance type pressing structure, and the bottom of the sand willow strip products 2 is inserted into the sandy soil. After the bottom of the group of sand willow strip products 2 is inserted into the sandy soil, the second motor 77 rotates the rotating shaft 75 and the driving gear 76 fixed on the rotating shaft 75 by 180° again through the output shaft, and under the meshing action, the driving gear 76 drives the corresponding driven gear plate 71 to rotate by 180°. At this time, during the rotation of the driven gear plate 71, the eccentric shaft 72 rotates away from the sliding block 74, at this time, the eccentric shaft 72 pulls the T-shaped slide rod 73 to make the horizontal end of the T-shaped slide rod 73 retract and reset, so that the nylon net 61 is attached to the side of the group of sand willow strip products 2 away from the vehicle body 1.

[0089] According to the above steps, the nylon net 61 is attached to the sand willow strip products 2 in an S shape.
