Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ecological restoration and forestry machinery, and particularly relates to a grass checkerboard sand barrier laying machine. BACKGROUND

[0002] Desertification is one of the major environmental problems and natural disasters that endanger human survival. Practice has proved that the most effective method in engineering sand control technology is to lay grass checkerboard. The working principle of the grass checkerboard laying machine is to quickly form a grass checkerboard in a mechanical insertion manner, which greatly improves the operation efficiency and reduces the operation cost.

[0003] Mechanized sand fixation not only ensures good sand control effect, but also improves the prevention and control efficiency, realizes mechanical equipment sand control, and speeds up the process of desertification control. Mechanized sand control is more scientific and efficient, and plays an important role in environmental protection and ecological construction, and is worth popularizing in future desert control.

[0004] With the continuous precision of sand fixation and afforestation, a large number of efficient and convenient sand fixation and afforestation mechanical equipment have been invented and created, which promotes the development of mechanized sand control technology. However, due to the uneven research and development team, the design and development are disconnected with production practice, and the benefit evaluation is missing, resulting in insufficient practicality of existing sand fixation and afforestation machinery, lagging behind in popularization and application, and the supporting potential of mechanized sand fixation and afforestation for precision sand control needs to be tapped.

[0005] The existing laying machines such as multifunctional three-dimensional sand fixation vehicle and traction type sand fixation vehicle, firstly adopt grass roller, which needs special mechanism to weave and cut, increasing the laying cost, control difficulty and precision. In addition, the thickness of the grass curtain is fixed during weaving, which cannot meet the laying requirements of various working environments on the thickness.

[0006] In view of the current desertification situation in China, in order to improve the existing sand control efficiency, reduce the sand control cost, improve the land desertification and protect the life of local people, it is necessary to construct a multifunctional three-dimensional sand fixation vehicle (grass checkerboard sand barrier laying machine) with high efficiency, high degree of automation and mechanization, and large area of controllable area per unit investment.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] Reference Figure 1 A grass checkerboard sand barrier laying machine includes a longitudinal mechanism 1, a transverse mechanism 2, a base plate 3, and tracks 4. Tracks 4 are mounted under the base plate 3, and the longitudinal mechanism 1 and transverse mechanism 2 are sequentially placed on the base plate 3 along the machine's forward direction. Power is provided by a motor 18 attached to the tracks 4, enabling the grass checkerboard sand barrier laying machine to complete movement along a designated path. The longitudinal mechanism 1 can continuously perform grass-pressing actions along the same straight line as the machine's forward direction; the transverse mechanism 2 can intermittently perform grass-pressing actions in a direction perpendicular to the machine's forward direction; the grass laid by the longitudinal mechanism 1 and the transverse mechanism 2 together form grass checkerboards of a designated size.

[0045] Reference Figure 2 The longitudinal mechanism 1 includes a trenching mechanism 5, a door opening mechanism 6, an eccentric wheel oscillation mechanism 7, a grass conveying mechanism 8, a longitudinal cutter head mechanism 9, a sand covering wheel mechanism 10, a sand pushing plate mechanism 11, and a longitudinal grass storage bin 12. The longitudinal grass storage bin 12 has a door opening mechanism 6 above one side of the grass checkerboard sand barrier laying machine in the forward direction, and an eccentric wheel oscillation mechanism 7 below the other side, and they are connected by an eccentric wheel 36. Below the door opening mechanism 6 is the grass conveying mechanism 8, and in front of the grass conveying mechanism 8 is the trenching mechanism 5. Below the longitudinal grass storage bin 12 is the longitudinal cutter head mechanism 9, which is linked to the sand pushing plate mechanism 11 located below the eccentric wheel oscillation mechanism 7 through a B worm gear 57 and a C worm gear 58. The longitudinal cutter head mechanism 9 is longitudinally linked to the sand covering wheel mechanism 10 through an H-axis 65.

[0046] Before the grass checkerboard sand barrier laying machine moves forward, the trenching mechanism 5 and the longitudinal cutter head mechanism 9 reach their working positions. When the grass checkerboard sand barrier laying machine moves forward, the loose grass and straw are transported from the longitudinal grass storage bin 12 to the ground through the door opening mechanism 6 and the grass conveying mechanism 8 under the action of the eccentric wheel oscillation mechanism 7. The longitudinal cutter head mechanism 9 completes the grass pressing action, and then the sand covering wheel mechanism 10 transports sand to the top of the loose grass, and the sand pushing plate mechanism 11 further fixes the loose grass.

[0047] Reference Figure 4 The trenching mechanism 5 includes an A motor 19, an A worm gear 20, an A gear 21, an A shaft 22, a D connecting rod 23, and a trencher 24; the power output shaft of the A motor 19 is fixedly connected to the A worm gear 20, and the A worm gear 20 meshes with the A gear 21; the A gear 21, the D connecting rod 23, and the trencher 24 are fixedly connected to the A shaft 22.

[0048] Before the grass checkerboard sand barrier laying machine moves forward, the motor drives the A worm gear 20 and A gear 21, causing the A shaft 22, which is fixed to the A gear 21, to rotate. This causes the D connecting rod 23 and the trench opener 24, which are mounted on the A shaft 22, to rotate downwards to the working position. When the grass checkerboard sand barrier laying machine moves forward, the slope of the trench opener 24 separates the sand from the middle, and pre-plows out the trenches for burying the grass stalks, which is convenient for subsequent rolling.

[0049] Reference Figure 5 The door opening mechanism 6 includes a B motor 25, a gearbox 26, an A rack 27, an A connecting rod 28, a B connecting rod 29, a C connecting rod 30, and an A plate 31. The power output shaft of the B motor 25 is connected to the power input shaft of the gearbox 26. The slot of the gearbox 26 is engaged with the A rack 27, allowing it to move only up and down. The gearbox 26 is fixedly connected to the A connecting rod 28. The B connecting rod 29 is hinged to both the A connecting rod 28 and the C connecting rod 30. The other end of the C connecting rod 30 is a fixed hinge support. The C connecting rod 30 is fixedly connected to the A plate 31.

[0050] When the grass checkerboard sand barrier laying machine moves forward, motor B 25 drives gearbox 26 to move up and down outside rack A 27, causing connecting rod A 28 to move up and down. Through the connection of connecting rod B 29, connecting rod C 30 and plate A 31 fixed thereon rotate around the fixed hinge support, thereby controlling the number of longitudinally laid grass rods falling from the longitudinal grass storage bin 12 to the grass conveying mechanism 8.

[0051] Reference Figure 6 The eccentric wheel oscillation mechanism 7 includes a C motor 32, a B gear 33, a C gear 34, a B shaft 35, an eccentric wheel 36, and a hay storage box bottom plate 37. The power output shaft of the C motor 32 is fixedly connected to the B gear 33, the B gear 33 meshes with the C gear 34, the C gear 34 and the eccentric wheel 36 are fixedly connected to the B shaft 35, and the eccentric wheel 36 is tangential to the hay storage box bottom plate 37 and locked by gravity.

[0052] When the door opening mechanism 6 is in the open state, the C motor 32 drives the B gear 33 and the C gear 34, causing the B shaft 35, which is fixed to the C gear 34, to rotate. This causes the eccentric wheel 36, which is mounted on the B shaft 35, to rotate, causing the bottom plate 37 of the hay storage box to change and generate slight vibrations, making it easier for the hay to overcome friction and static electricity and slide down.

[0053] Reference Figure 7The grass conveying mechanism 8 includes a D motor 38, a D gear 39, an E gear 40, a C shaft 41, a D shaft 42, an A grass-grooming wheel 43, a B grass-grooming wheel 44, an F gear 45, a G gear 46, an H gear 47, a chain 48, an I gear 49, an E shaft 50, an F shaft 51, an A pulley 52, a B pulley 53, and a belt 54. The power output shaft of motor D38 is fixedly connected to gear D39; gear D39 meshes with gear E40; gear E40, A grass-grooming wheel 43, F gear 45, and H gear 47 are fixedly connected to shaft C41; similarly, grass-grooming wheel B44 and gear G46 are fixedly connected to shaft D42. Grass-grooming wheels A43 and B44 are placed in two rows, rotate relative to each other, and are 1 / 4 cycle out of phase to avoid mutual interference; gear F45 and gear G46 mesh, and gear H47 and gear I49 are connected by chain 48; gear I49 and pulley A52 are fixedly connected to shaft E50; similarly, pulley B53 is fixedly connected to shaft F51, and pulley A52 and pulley B53 are connected by belt 54.

[0054] When the grass checkerboard sand barrier laying machine moves forward, motor D38 drives gears D39 and E40 to rotate, which in turn drives grass-setting wheel A43, which is fixed to shaft C41 connected to gear D39, to rotate. On the other side, gear F45 meshes with gear G46, which drives grass-setting wheel B44, which is fixed to shaft D42 connected to gear G46, to rotate in the opposite direction. Grass-setting wheel B44 and grass-setting wheel A43 are out of phase by 1 / 4 cycle to avoid mutual interference. Gear H47 and gear I49, which are fixed to shaft C41, rotate synchronously through chain 48, which drives pulley A52, which is fixed to shaft E50 connected to gear I49, to rotate. This causes belt 54 to be tensioned and rotated between pulley A52 and pulley B53. After the grass stalks enter the grass conveying mechanism 8, they are combed by grass-setting wheel B44 and grass-setting wheel A43 and conveyed by belt 54, and then spread evenly on the sand surface with a certain thickness and density.

[0055] Reference Figure 8 The longitudinal cutter head mechanism 9 includes an E motor 55, a gear train mechanism 56, a B worm gear 57, a C worm gear 58, an A nut 59, a B nut 60, a four-bar linkage 61, a G shaft 62, and a longitudinal cutter head 63. The E motor 55, the B worm gear 57, and the C worm gear 58 are connected by the gear train mechanism 56. The A nut 59 and the B nut 60 are respectively screwed onto the B worm gear 57 and the C worm gear 58. The four-bar linkage 61 is internally hinged, with two of its links fixedly connected to the B worm gear 57 and the C worm gear 58, and one end of the other main link sleeved on the G shaft 62, with the other end serving as a fixed hinge support. The G shaft 62 is fixedly connected to the longitudinal cutter head 63.

[0056] Before the grass checkerboard sand barrier laying machine moves forward, the gear train mechanism 56, consisting of motor E 55 and gears 96, 97, and 98, drives worm B 57 and worm C 58 to rotate, thereby causing nut A 59 on worm B 57 and nut B 60 on worm C 58 to move linearly. Nut A 59, nut B 60, and connecting rods 99, 100, 101, and 102 together form a synchronous four-bar linkage 61, with G-axis 62 as the output shaft, which in turn drives the longitudinal cutter head 63 to the working position. When the grass checkerboard sand barrier laying machine moves forward, the longitudinal cutter head 63 is passively rotated around G-axis 62 under the action of sand friction.

[0057] The longitudinal cutter disc 63 is trapezoidal in shape and acts as a clamp to restrict the grass stalks from sliding on the sand.

[0058] Reference Figure 9 The sand-pushing plate mechanism 11 includes symmetrically arranged sand-pushing plates A 69 and B 70. Sand-pushing plate A 69 is fixedly connected to shaft I 67. A bevel gear C 107 is sleeved on shaft I 67, meshing with bevel gear A 105. Bevel gear A 105 is coaxially connected to worm gear 103, which meshes with worm gear B 57 of the longitudinal cutter head mechanism 9. Similarly, sand-pushing plate B 70 is arranged in the same way as sand-pushing plate A 69. Sand-pushing plate B 70 is fixedly connected to shaft 68, and a bevel gear D 108 is sleeved on shaft 68, meshing with bevel gear B 106. Bevel gear B 106 is coaxially connected to worm gear 104, which meshes with worm gear C 58 of the longitudinal cutter head mechanism 9.

[0059] The A-push sand plate 69 and B-push sand plate 70 are arranged symmetrically, forming an angle of ±30° with the longitudinal center line, respectively.

[0060] Before the grass checkerboard sand barrier laying machine moves forward, the gear train mechanism 56, consisting of motor E 55 and gears 96, 97, and 98, drives worm B 57 and worm C 58 to rotate. This causes worm wheel 103, which meshes with worm B 57, and worm wheel 104, which meshes with worm C 58, to rotate. Using worm wheels 103 and 104 as the power source, the gear train structure 66, consisting of worm wheels 103 and 104, bevel gear A 105, bevel gear B 106, bevel gear C 107, and bevel gear D 108, outputs the rotation of shaft I 67 and shaft 68, thereby causing sand-pushing plates A 69 and B 70 to reach the working position. When the grass checkerboard sand barrier laying machine moves forward, sand-pushing plates A 69 and B 70 remain fixed.

[0061] Reference Figure 3The transverse mechanism 2 includes a transverse grass-pushing mechanism 14 and a longitudinal grass-pushing mechanism 15 placed vertically on the platform 83. A grass-releasing mechanism 13 is located directly above the transverse grass-pushing mechanism 14 and the longitudinal grass-pushing mechanism 15. A transverse grass storage bin 17 is located directly above the grass-releasing mechanism 13. A blade-inserting mechanism 16 is located behind the platform 83. When the grass checkerboard sand barrier laying machine moves forward, the loose grass material passes through the grass-releasing mechanism 13 under the action of gravity, and then passes through the transverse grass-pushing mechanism 14 and the longitudinal grass-pushing mechanism 15 to reach the ground. The grass is then pressed down by the blade-inserting mechanism 16.

[0062] Reference Figure 10 The grass-laying mechanism 13 includes an F motor 71, a J gear 72, a K gear 73, a J shaft 74, a K shaft 75, a B plate 76, and a C plate 77. The F motor 71 drives the J gear 72 through a reduction gearbox. The J gear 72 meshes with the K gear 73. The J gear 72 and the B plate 76 are fixedly connected to the J shaft 74. Similarly, the K gear 73 and the C plate 77, which are symmetrically distributed therewith, are fixedly connected to the K shaft 75. The B plate 76 and the C plate 77 are tightly fitted together, and the gap between them is sealed with tape.

[0063] During the working cycle of the transverse mechanism 2, the F motor 71 drives the J gear 72 and K gear 73 to rotate around the J axis 74 and K axis 75, thereby causing the B plate 76 and C plate 77, which are fixed on the J axis 74 and K axis 75, to rotate to the working position. During the non-working cycle of the transverse mechanism 2, the F motor 71 reverses and causes the B plate 76 and C plate 77 to rotate to the stop position in the same way.

[0064] Reference Figure 11 The transverse grass-pushing mechanism 14 includes a G motor 78, an L gear 79, a B rack 80, a connector 81, a grass-pushing plate 82, and a platform 83. The power output shaft of the G motor 78 is fixedly connected to the L gear 79, and the G motor 78 is mounted on the connector 81. The L gear 79 meshes with the B rack 80, which is fixed on the overall frame of the transverse grass-pushing mechanism 14. The G motor 78 and the L gear 79 ensure that the whole mechanism does not deviate or rotate when it moves on the B rack 80. The connector 81 is fixedly connected to the grass-pushing plate 82, and the grass-pushing plate 82 is movably connected to the platform 83 through the B rack 80. The surface of the platform 83 has a textured surface to ensure the parallelism of the grass and prevent it from intersecting.

[0065] During the working cycle of the horizontal mechanism 2, the G motor 78 drives the L gear 79, which causes the L gear 79 and the connecting piece 81 to move linearly on the B rack 80, thereby driving the grass pusher 82 to move linearly relative to the platform 83, thus spreading the grass.

[0066] Reference Figure 12The longitudinal grass-pushing mechanism 15 includes an electric actuator 84, a scissor mechanism 85, a brush 86, and a platform 83. The output end of the electric actuator 84 is hinged to the O-axis 110. The O-axis 110, P-axis 111, Q-axis 112, R-axis 113, S-axis 114, T-axis 115, U-axis 116, V-axis 117, W-axis 118, X-axis 119, A-rod 120, B-rod 121, C-rod 122, D-rod 123, E-rod 124, F-rod 125, G-rod 126, H-rod 127, I-rod 128, J-rod 129, K-rod 130, and L-rod 131 constitute the scissor mechanism 85. The P-axis 111 is fixed on the platform 83, and the brush 86 is mounted on the X-axis 119 to ensure that the grass stalks located at the concave and convex points of the platform can be pushed simultaneously, making the grass mat flat.

[0067] During the working cycle of the transverse mechanism 2, after the transverse grass-pushing mechanism 14 finishes working, the electric actuator 84 drives the O-axis 110 to move vertically downwards. This, in turn, drives the brush 86 to move linearly relative to the platform 83 through the scissor mechanism 85, which consists of the P-axis 111, Q-axis 112, R-axis 113, S-axis 114, T-axis 115, U-axis 116, V-axis 117, W-axis 118, X-axis 119, A-bar 120, B-bar 121, C-bar 122, D-bar 123, E-bar 124, F-bar 125, G-bar 126, H-bar 127, I-bar 128, J-bar 129, K-bar 130, and L-bar 131. The direction of the movement is perpendicular to the transverse grass-pushing mechanism 14.

[0068] Reference Figure 13 The inserting mechanism 16 includes an H motor 88, an M gear 89, an N gear 90, an L shaft 91, a linkage mechanism 92, an M shaft 93, an N shaft 94, and an inserting blade 95. The power output shaft of the H motor 88 is fixedly connected to the M gear 89, the M gear 89 meshes with the N gear 90, and the N gear 90 and the crank wheel 132 are fixedly connected to the L shaft 91. The linkage mechanism 92 is composed of the crank wheel 132, the M rod 134, the N rod 135, the O rod 136, the P rod 137, the Q rod 138, the R rod 139, the S rod 140, the T rod 141, the U rod 142, the V rod 143, the W rod 144, and the X rod 145. The P rod 137 and the Q rod 138 are connected to the inserting blade 95 through the M shaft 93 and the N shaft 94, respectively.

[0069] The bottom of the 95-inch blade is trapezoidal and toothed, which makes it easier to insert into the sand and improves the effect of inserting grass.

[0070] When the grass checkerboard sand barrier laying machine moves forward, the H motor 88 drives the M gear 89 to rotate, causing the N gear 90 and L shaft 91, which mesh with it, to rotate. The L shaft 91 serves as the power source, driving the linkage mechanism 92, which consists of crank wheel 132, crank wheel 133, M rod 134, N rod 135, O rod 136, P rod 137, Q rod 138, R rod 139, S rod 140, T rod 141, U rod 142, V rod 143, W rod 144, and X rod 145, to move. The M shaft 93 and N shaft 94 drive the cutting tool 95 as the output.

[0071] The working principle of this invention is explained as follows:

[0072] Working process of the grass checkerboard sand barrier laying machine: Before starting work, the driver starts the E motor 55 in the longitudinal cutter head mechanism 9. The motor drives the wheel system mechanism 56 to rotate, which outputs through the four-bar linkage 61, causing the longitudinal cutter head 63 to be obliquely inserted into the sand around the G axis 62 and reach the working position. The rotation of the wheel system mechanism 56 simultaneously outputs through the wheel system structure 66, causing the A sand pushing plate 69 and B sand pushing plate 70 to reach the working position. At the same time, the A motor 19 in the trenching mechanism 5 starts, which, through the trenching mechanism 5, causes the trencher 24 to be obliquely inserted into the sand around the A axis 22 and reach the working position. Then, the motor 18 drives the track 3 to rotate, causing the grass checkerboard sand barrier laying machine to start moving forward in a straight line. Then, the longitudinal and transverse mechanisms start working, continuously completing the longitudinal grass checkerboard laying while intermittently completing the transverse grass checkerboard laying. After the work is completed, the motor 18 stops rotating, and the entire machine stops.

[0073] Longitudinal mechanism for grass compaction: During the working process, motor B 25 in the door opening mechanism 6 drives plate A 31 to rotate around the fixed hinge support. Then, motor C 32 in the eccentric wheel oscillation mechanism 7 starts, driving eccentric wheel 36 to rotate around shaft B 35, thereby causing the bottom plate of the grass storage box to vibrate. Therefore, the loose grass in the longitudinal grass storage bin 12 overcomes friction and slides down to the grass conveying mechanism 8. After entering the grass conveying mechanism 8, the loose grass is combed by grass-sorting wheels B 44 and A 43 and conveyed by belt 54, spreading evenly on the sand surface with a certain thickness and density. After the loose grass is laid on the ground, it is compacted by the longitudinal cutter head 63, covered with sand by the sand-covering wheel mechanism 10, and pushed by the sand-pushing plate mechanism 11, finally completing the laying of the entire longitudinal grass grid. After the grass grid sand barrier laying machine finishes laying, motor E 55 and motor A 19 reverse, driving the longitudinal cutter head mechanism 9, sand-pushing plate mechanism 11, and trenching mechanism 5 back to their initial positions.

[0074] The horizontal grass pressing process: At the start of operation, the grass checkerboard sand barrier laying machine has already moved forward in a straight line. During the working cycle, the H motor 88 of the blade insertion mechanism 16 starts, driving the linkage mechanism 92, ultimately causing the blade 95 to make intermittent vertical linear movements relative to the ground. The F motor 71 in the grass releasing mechanism 13 drives the B plate 76 and C plate 77 to rotate around the J axis 74 and K axis 75, thereby causing the loose grass to fall from the horizontal grass storage bin 17 to the platform 83 of the horizontal grass pushing mechanism 14 under gravity. Then, the G motor 78 starts, driving the grass pushing plate 82 to move linearly along the platform 83, causing the loose grass to be evenly spread horizontally along the platform 83. Then, the electric push rod 84 of the longitudinal grass pushing mechanism 15 extends, driving the O axis 110 to move vertically downward, driving the brush 86 to move linearly relative to the platform 83 through the scissor mechanism 85, with the direction of movement perpendicular to the horizontal grass pushing mechanism 14. After the loose grass falls to the ground, the electric push rod 84 retracts, driving the longitudinal grass pushing mechanism 15 back to its initial state. The loose grass is pressed into the ground by the inserting blade 95, completing the laying of the horizontal grass grid. After the longitudinal grass pushing mechanism 15 returns to its initial position, the G motor 78 of the transverse grass pushing mechanism 14 reverses, driving the transverse grass pushing mechanism 14 back to its initial state. The transverse mechanism enters a non-working cycle until the next working cycle. After the grass grid sand barrier laying machine finishes its work, the transverse mechanism remains in the non-working cycle position.
