Detailed implementation manners

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0016] The present invention provides a greening device for alpine and high-steep slopes. As Figures 1 to 6 shown, it includes an ecological bag 1. The ecological bag 1 is an ecological long bag in the prior art. Soil, fertilizer, and seeds are segmented and filled into the ecological bag 1. After a period of cultivation, the grown plants penetrate through the ecological bag, enabling the greening of the slope. A cylinder body 2 is inserted at the end of the ecological bag 1. The cylinder body 2 and the ecological bag 1 are connected by binding with a binding rope 3. After the ecological bag 1 is filled, by removing the binding rope 3, the cylinder body 2 can be separated from the ecological bag 1, enabling the use of the next ecological bag 1. A support assembly for supporting the ecological bag 1 is provided on the cylinder body 2; The support assembly includes: a rotating rod 4, a wire reel 5, a rope 6, an annular plate 7, a driving assembly for driving the rotation of the rotating rod 4, a first fixing assembly for fixing the cylinder body 2, and a second fixing assembly for fixing the annular plate 7. An annular cavity is provided inside the cylinder body 2. A plurality of rotating rods 4 are rotatably installed in the annular cavity at equal intervals. The wire reel 5 is fixedly sleeved outside the rotating rod 4. One end of the rope 6 is fixedly connected to the wire reel 5. The rope 6 is wound inside the wire reel 5. The other end of the rope 6 passes through the annular cavity and is fixedly connected to the annular plate 7. The annular plate 7 is sleeved outside the ecological bag 1.

[0017] During use, the cylinder body 2 is fixed at the top of the slope through the first fixing assembly. Subsequently, the driving assembly drives the rotating rod 4 to drive the wire reel 5 to rotate forward, so that the rope 6 is released. The rope 6 is a steel cable. Then, the annular plate 7 is pulled to move along the ecological bag 1 to the bottom of the slope. Subsequently, the annular plate 7 is fixed at the bottom of the slope through the second fixing assembly. At this time, the whole formed by the rope 6, the annular plate 7, and the cylinder body 2 wraps the ecological bag 1, so that the ecological bag 1 is supported. Then, a mixture of soil, fertilizer, and seeds (hereinafter referred to as materials) is poured into the cylinder body 2. The materials slide down along the ecological bag 1 to the bottom of the ecological bag 1. During the sliding process, since the ecological bag 1 is supported, there will be no situation where the part of the ecological bag 1 without materials falls into the depression on the slope, resulting in the materials piling up in the slope depression when sliding and unable to slide smoothly to the bottom of the ecological bag 1. Thus, it is ensured that the materials can slide smoothly to the bottom of the ecological bag 1. As the materials are added, after adding a section, the fixation of the annular plate 7 by the second fixing assembly is cancelled. Subsequently, the driving assembly drives the rotating rod 4 to drive the wire reel 5 to rotate in the reverse direction, so that the rope 6 is wound up, thereby driving the annular plate 7 to move. When the annular plate 7 moves away from the ecological bag 1 filled with materials, the upper part of the ecological bag 1 filled with materials is tied through an external strap. Subsequently, part of the ecological bag 1 filled with materials is fixed to the slope through an anchor rod. Then, the annular plate 7 is fixed again through the second fixing assembly. The subsequent operations are the same as the above, and the pouring of materials continues. The above operations are repeated until the entire ecological bag 1 is filled and fixed in segments, and finally the filling of the ecological bag 1 is completed.

[0018] As Figure 1 、 Figure 3 and Figure 4 As shown in One end of the rotating rod 4 extends outside the annular cavity and is fixedly connected to the gear 8. A circular groove is opened on the outer side of the cylinder body 2. The turntable 9 is rotatably installed in the circular groove. The teeth 10 are arranged at equal intervals around the bottom of the turntable 9. The teeth 10 are meshed with the gear 8. The screw rod 11 is threadedly connected to the turntable 9. One end of the screw rod 11 extends into the circular groove.

[0019] Rotate the forward screw 11 to move its end away from the inner wall of the circular groove. Rotate the forward turntable 9 so that its mating teeth 10 drive the gear 8 to rotate forward, thereby driving the rotating rod 4 to rotate forward. Conversely, rotating the turntable 9 in the reverse direction can achieve the reverse rotation of the rotating rod 4. Rotate the reverse screw 11 so that its end abuts against the inner wall of the circular groove. Relying on the frictional force between the screw 11 and the inner wall of the circular groove, the turntable 9 can be fixed.

[0020] As Figures 2 to 6 shown, a lubrication assembly for lubricating the contact surface between the ring plate 7 and the ecological bag 1 is provided on the ring plate 7; The lubrication assembly includes: a circular cavity 13 provided in the ring plate 7, a spray pipe 14, and an injection assembly for injecting lubricating fluid into the circular cavity 13. The lubricating fluid is edible oil; The spray pipes 14 are arranged equidistantly around the inner side of the ring plate 7, and one end of the spray pipe 14 is communicated with the inside of the circular cavity 13.

[0021] When the ring plate 7 slides along a part of the ecological bag 1 filled with materials, the friction between the ring plate 7 and the ecological bag 1 is large, resulting in a large resistance when the ring plate 7 moves, so it is very difficult to rotate the turntable 9. Therefore, lubricating fluid is injected into the circular cavity 13 through the injection assembly. The lubricating fluid then flows out through the spray pipe 14 to the surface of the ecological bag 1, so that when the ring plate 7 is pulled subsequently, the ring plate 7 and the ecological bag 1 are lubricated, greatly reducing the friction force and making it easy to pull the ring plate 7, facilitating the operation.

[0022] As Figures 2 to 6 shown, the injection assembly includes: a cavity 15 provided on the ring plate 7, a liquid storage cavity 16 provided on the ring plate 7, a first channel 17 connecting the cavity 15 and the circular cavity 13, a second channel 18 connecting the liquid storage cavity 16 and the cavity 15, a one-way valve 19, and an extrusion assembly for extruding the lubricating oil in the cavity 15: The one-way valve 19 is arranged in the first channel 17, the second channel 18 and the spray pipe 14. A liquid adding port communicated with the liquid storage cavity 16 is provided on the outer side of the ring plate 7, and a plunger is threadedly connected in the liquid adding port.

[0023] When the fixation of the second fixing component on the ring plate 7 is cancelled, at this time the ring plate 7 loses support, so that a part of the ecological bag 1 filled with materials presses on the ring plate 7, causing the ring plate 7 to contact the slope. At this time, the extrusion component extrudes the lubricating oil in the cavity 15. At this time, the one-way valve 19 in the first channel 17 opens, and the one-way valve 19 in the second channel 18 closes. The lubricating oil is squeezed into the circular cavity 13, and then after filling the circular cavity 13, it pushes open the one-way valve 19 in the spray pipe 14 and sprays onto the ecological bag 1. When the ring plate 7 is lifted and fixed again to obtain support, at this time the extrusion component works in reverse, and at this time lubricating oil is replenished into the cavity 15. At this time, the one-way valves 19 in the first channel 17 and the spray pipe 14 close, and the one-way valve 19 in the second channel 18 opens. The lubricating oil in the liquid storage cavity 16 is pumped into the cavity 15 for replenishment.

[0024] As Figures 5 to 6 shown, the extrusion component includes: a piston 20, a connecting rod 21, a spring 22, a bottom plate 23, and a ball 24; The piston 20 is arranged in the cavity 15. There are two connecting rods 21, and both are fixedly connected to the side of the piston 20 away from the ecological bag 1. The end of the connecting rod 21 away from the piston 20 extends outside the cavity 15 and is fixedly connected to the bottom plate 23. The spring 22 is sleeved outside the connecting rod 21. The bottom plate 23 is arc-shaped, and the balls 24 are equidistantly and rotatably installed on the side of the bottom plate 23 away from the ecological bag 1.

[0025] After the ring plate 7 loses fixation, a part of the ecological bag 1 filled with materials presses down the ring plate 7, causing the bottom plate 23 to contact the slope. At this time, as the ring plate 7 continues to be pressed down, the piston 20 moves relative to the cavity 15, squeezing the lubricating oil in the cavity 15 outwards. At the same time, the ring plate 7 compresses the spring 22. When the ring plate 7 is lifted and fixed again, the bottom plate 23 leaves the slope. At this time, the spring 22 drives the bottom plate 23 to reset, driving the connecting rod 21 and the piston 20 to move and reset accordingly, replenishing the lubricating oil into the cavity 15.

[0026] As Figure 1 shown, the first fixing component includes: a first connecting block 27 and a first lead screw 28; There are two first connecting blocks 27, which are symmetrically and fixedly installed on the outer side of the cylinder body 2. The first lead screw 28 is threadedly connected to the first connecting block 27, and both ends of the first lead screw 28 pass through the first connecting block 27.

[0027] Rotate the first lead screw 28 forward to make it move relative to the first connecting block 27, and then embed one end of the first lead screw 28 into the slope ground, so as to cooperate with the first connecting block 27 to support the cylinder body 2, making the cylinder body 2 leave the ground. Adjusting the position of the first lead screw 28 relative to the first connecting block 27 can achieve the adjustment of the height of the cylinder body 2.

[0028] As Figure 1As shown, the second fixing component includes: a second connecting block 25 and a second screw rod 26; There are two second connecting blocks 25, which are symmetrically and fixedly installed on the outer side of the annular plate 7. The second screw rod 26 is threadedly connected to the second connecting block 25, and both ends of the second screw rod 26 pass through the second connecting block 25.

[0029] Rotate the second screw rod 26 forward to make it move relative to the second connecting block 25, and then embed the end of the second screw rod 26 into the slope, so that the annular plate 7 can be supported and fixed. Adjust the position between the second screw rod 26 and the second connecting block 25, so as to adjust the supporting height of the annular plate 7.

[0030] As Figure 2 shown, one end of both the first screw rod 28 and the second screw rod 26 is provided with a tapered end.

[0031] This makes it convenient for the first screw rod 28 and the second screw rod 26 to be embedded into the slope ground for fixation.

[0032] Working principle: When in use, rotate the first lead screw 28 forward to make it move relative to the first connecting block 27, and then embed one end of the first lead screw 28 into the slope ground, so as to cooperate with the first connecting block 27 to support the cylinder body 2, making the cylinder body 2 leave the ground. Adjusting the position between the first lead screw 28 and the first connecting block 27 can realize the adjustment of the height of the cylinder body 2. After fixing the cylinder body 2 at the top of the slope, then rotate the screw 11 forward to make its end leave the inner wall of the circular groove. Rotate the turntable 9 forward to drive the gear 8 to rotate forward through the teeth 10, thereby driving the rotating rod 4 to rotate forward, and then driving the wire reel 5 to rotate forward, so as to release the rope 6. The rope 6 is a steel cable. Then pull the ring plate 7 to move along the ecological bag 1 to the bottom of the slope. Rotate the second lead screw 26 forward to make it move relative to the second connecting block 25, and then embed the end of the second lead screw 26 into the slope, so as to support and fix the ring plate 7. At this time, the bottom of the ring plate 7 leaves the slope. At this time, the overall composed of the rope 6, the ring plate 7 and the cylinder body 2 wraps the ecological bag 1, so that the ecological bag 1 is supported. Then pour the mixture of soil, fertilizer and seeds (hereinafter referred to as materials) into the cylinder body 2. The materials slide down along the ecological bag 1 to the bottom of the ecological bag 1. During the sliding process, since the ecological bag 1 is supported, there will be no situation where the part of the ecological bag 1 without materials falls into the depression on the slope, resulting in the materials piling up in the slope depression when sliding and unable to slide smoothly to the bottom of the ecological bag 1. Thus, it is ensured that the materials can slide smoothly to the bottom of the ecological bag 1. With the addition of materials, when a section is added, separate the second lead screw 26 from the slope ground, then rotate the second lead screw 26 in reverse to reset it, and then rotate the turntable 9 in reverse, vice versa, to realize the reverse rotation of the wire reel 5 and wind up the rope 6, thereby driving the ring plate 7 to move. When the ring plate 7 moves to leave the ecological bag 1 filled with materials, tie the upper part of the ecological bag 1 filled with materials with an external strap, and then fix part of the ecological bag 1 filled with materials to the slope through an anchor bolt. Then repeat the above operation to lift the position of the ring plate 7, support and fix it to make it leave the ground. The subsequent operations are the same as above, continue to pour materials, and repeat the above operation until the entire ecological bag 1 is filled and fixed in segments, and finally complete the filling of the ecological bag 1; When adjusting the position of the ring plate 7, it moves along the surface of the ecological bag 1. When the ring plate 7 slides along a part of the ecological bag 1 filled with materials, the friction between the ring plate 7 and the ecological bag 1 is large, resulting in a large resistance when the ring plate 7 moves, so it is very difficult to rotate the turntable 9. Therefore, when the ring plate 7 loses support and fixation, the part of the ecological bag 1 filled with materials presses down the ring plate 7, causing the bottom plate 23 to contact the slope. At this time, as the ring plate 7 continues to be pressed down, the piston 20 moves relative to the cavity 15, squeezing the lubricating oil in the cavity 15 outwards. At the same time, the ring plate 7 compresses the spring 22. At this time, the one-way valve 19 in the first channel 17 opens, and the one-way valve 19 in the second channel 18 closes. The lubricating oil is squeezed into the circular cavity 13 and then ejects through the one-way valve 19 in the spray pipe 14 onto the ecological bag 1 after filling the circular cavity 13. Subsequently, when the ring plate 7 moves, the lubrication between the ring plate 7 and the ecological bag 1 is achieved, greatly reducing the friction force and making the pulling of the ring plate 7 easier, facilitating the operation. The movement of the bottom plate 23 relative to the ground is facilitated by the ball 24. When the ring plate 7 is lifted and fixed again, the bottom plate 23 leaves the slope. At this time, the spring 22 drives the bottom plate 23 to reset, causing the connecting rod 21 and the piston 20 to move and reset accordingly, replenishing the lubricating oil into the cavity 15. At this time, the one-way valve 19 in the first channel 17 and the spray pipe 14 closes, and the one-way valve 19 in the second channel 18 opens. The lubricating oil in the liquid storage cavity 16 is pumped into the cavity 15 for replenishment.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it.
