[0025] In order to make the purpose, 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.

[0026] The present invention provides a greening device for high-cold and steep slopes, such as Figures 1 to 6As shown, it includes an eco-bag 1, which is an eco-long bag in the prior art. Soil, fertilizer, and seeds are placed in sections in the eco-bag 1. After a period of cultivation, the grown plants pass through the eco-bag, so that the slope can be greened. The end of the eco-bag 1 is plugged with a cylinder 2, and the cylinder 2 and the eco-bag 1 are tied together by a binding rope 3. After the eco-bag 1 is filled, the binding rope 3 can be removed to separate the cylinder 2 from the eco-bag 1, so that the next eco-bag 1 can be used. A support component for supporting the eco-bag 1 is provided on the cylinder 2;

[0027] The support assembly includes: a rotating rod 4, a take-up drum 5, a rope 6, a ring plate 7, a driving assembly for driving the rotating rod 4 to rotate, a first fixing assembly for fixing the cylinder 2, and a second fixing assembly for fixing the ring plate 7;

[0028] An annular cavity is provided inside the cylinder 2, and multiple rotating rods 4 are installed in the annular cavity and rotate equidistantly. The take-up drum 5 is fixedly sleeved on the outside of the rotating rod 4, one end of the rope 6 is fixedly connected to the take-up drum 5, and the rope 6 is wound in the take-up drum 5. The other end of the rope 6 passes through the annular cavity and is fixedly connected to the ring plate 7, and the ring plate 7 is sleeved on the outside of the ecological bag 1.

[0029] When in use, the cylinder 2 is fixed to the top of the slope through the first fixing component, and then the driving component drives the rotating rod 4 to rotate forward with the take-up drum 5 to release the rope 6. The rope 6 is a steel cable, and then the ring plate 7 is pulled to move it along the eco-bag 1 to the bottom of the slope, and then the ring plate 7 is fixed to the bottom of the slope through the second fixing component. At this time, the rope 6, the ring plate 7, and the cylinder 2 form a whole that wraps the eco-bag 1, so that the eco-bag 1 is supported. Then, soil, fertilizer, and seed mixture are poured into the cylinder 2. The material slides down along the eco-bag 1 to the bottom of the eco-bag 1. During the sliding process, since the eco-bag 1 is supported, the part of the eco-bag 1 that is not filled with material will not fall into the depression on the slope, causing the material to accumulate in the depression of the slope when it slides down, and it cannot The bag 1 is then moved to the bottom of the bag 1 and the bag is then moved to the bottom of the bag 1. The bag 1 is ...

[0030] like Figure 1 、 Figure 3 and Figure 4 As shown, the driving assembly includes: a gear 8, a rotary disk 9, teeth 10, a screw 11, and a guide port 12 provided on the rotary disk 9;

[0031] One end of the rotating rod 4 extends to the outside of the annular cavity and is fixedly connected to the gear 8. A circular groove is provided on the outside of the cylinder 2. The turntable 9 is rotatably installed in the circular groove. The teeth 10 are equidistantly arranged around the bottom of the turntable 9. The teeth 10 are engaged with the gear 8. The screw 11 is threadedly connected to the turntable 9, and one end of the screw 11 extends into the circular groove.

[0032] The forward rotating screw 11 causes its end to leave the inner wall of the circular groove, and the forward rotating turntable 9 causes its cooperating teeth 10 to rotate forward with the gear 8, thereby causing the rotating rod 4 to rotate forward. Conversely, reversing the turntable 9 can realize the reverse rotation of the rotating rod 4, and reversing the screw 11 causes its end to contact the inner wall of the circular groove. Relying on the friction between the screw 11 and the inner wall of the circular groove, the turntable 9 can be fixed.

[0033] like Figures 2 to 6 As shown, the ring plate 7 is provided with a lubrication component for lubricating the contact surface between the ring plate 7 and the eco-bag 1;

[0034] The lubrication assembly includes: a circular cavity 13 provided in the ring plate 7, a nozzle 14, and an injection assembly for injecting lubricating liquid into the circular cavity 13, wherein the lubricating liquid is edible oil;

[0035] The nozzles 14 are equidistantly arranged around the inner side of the ring plate 7 , and one end of the nozzles 14 is communicated with the interior of the circular cavity 13 .

[0036] When the ring plate 7 slides along the part of the eco-bag 1 filled with materials, the friction between the ring plate 7 and the eco-bag 1 is large, which causes the ring plate 7 to encounter large resistance during movement, making it very difficult to rotate the turntable 9. Therefore, lubricating liquid is injected into the circular cavity 13 through the injection component, and the lubricating liquid then flows out to the surface of the eco-bag 1 through the nozzle 14, so that when the ring plate 7 is pulled subsequently, the ring plate 7 and the eco-bag 1 are lubricated, which greatly reduces the friction, makes the pulling of the ring plate 7 easy, and facilitates the operation.

[0037] like Figures 2 to 6 As 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 with the circular cavity 13, a second channel 18 connecting the liquid storage cavity 16 with the cavity 15, a one-way valve 19, and an extrusion assembly for squeezing the lubricating oil out of the cavity 15:

[0038] The one-way valve 19 is arranged in the first channel 17, the second channel 18 and the nozzle 14. The outer side of the ring plate 7 is provided with a liquid filling port connected to the liquid storage chamber 16, and a plunger is connected to the inner thread of the liquid filling port.

[0039] When the second fixing component is cancelled to fix the ring plate 7, the ring plate 7 loses its support, so that the part of the eco-bag 1 filled with materials squeezes the ring plate 7, causing the ring plate 7 to conflict with the slope. At this time, the extrusion component squeezes out the lubricating oil in the cavity 15. At this time, the one-way valve 19 in the first channel 17 is opened, and the one-way valve 19 in the second channel 18 is closed. The lubricating oil is squeezed into the circular cavity 13, and then after filling the circular cavity 13, the one-way valve 19 in the nozzle 14 is pushed open and sprayed onto the eco-bag 1. When the ring plate 7 is lifted, it is fixed again and supported. At this time, the extrusion component works in reverse, and the lubricating oil is replenished in the cavity 15. At this time, the one-way valve 19 in the first channel 17 and the nozzle 14 are closed, and the one-way valve 19 in the second channel 18 is opened. The lubricating oil in the liquid storage chamber 16 is drawn into the cavity 15 for replenishment.

[0040] like Figures 5 and 6 As shown, the extrusion assembly includes: a piston 20, a connecting rod 21, a spring 22, a base plate 23, and a ball 24;

[0041] The piston 20 is arranged in the cavity 15, and there are two connecting rods 21, both of which are fixedly connected to the side of the piston 20 away from the eco-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 on the outside of the connecting rod 21, the bottom plate 23 is arc-shaped, and the ball 24 is equidistantly rotated and installed on the side of the bottom plate 23 away from the eco-bag 1.

[0042] After the ring plate 7 loses its fixation, the eco-bag 1 filled with materials partially presses down the ring plate 7, causing the bottom plate 23 to come into conflict with 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 outward. 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 brings the bottom plate 23 back to its original position, causing the connecting rod 21 and the piston 20 to move and reset accordingly, thereby replenishing the lubricating oil into the cavity 15.

[0043] like Figure 1 As shown, the first fixing assembly includes: a first connecting block 27 and a first screw rod 28;

[0044] Two first connecting blocks 27 are provided and symmetrically fixedly installed on the outside of the cylinder 2 . The first screw rod 28 is threadedly connected to the first connecting block 27 , and both ends of the first screw rod 28 pass through the first connecting block 27 .

[0045] The first screw rod 28 is rotated forward to move it relative to the first connecting block 27, and then one end of the first screw rod 28 is embedded in the slope ground so that it can cooperate with the first connecting block 27 to support the cylinder 2, so that the cylinder 2 leaves the ground. The position of the first screw rod 28 relative to the first connecting block 27 can be adjusted to adjust the height of the cylinder 2.

[0046] like Figure 1 As shown, the second fixing assembly includes: a second connecting block 25 and a second screw rod 26;

[0047] Two second connecting blocks 25 are provided and symmetrically fixedly mounted on the outer side of the ring 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 .

[0048] The second screw rod 26 is rotated forward to move it relative to the second connecting block 25, and then the end of the second screw rod 26 is embedded in the slope so that the ring plate 7 can be supported and fixed. The position of the second screw rod 26 relative to the second connecting block 25 is adjusted to adjust the support height of the ring plate 7.

[0049] like Figure 2 As shown, one end of the first screw rod 28 and the second screw rod 26 are both configured as pointed cone ends.

[0050] This makes it easier for the first screw rod 28 and the second screw rod 26 to be embedded in the slope ground for fixation.

[0051] Working principle: When in use, the first screw rod 28 is rotated forward to make it move relative to the first connecting block 27, and then one end of the first screw rod 28 is embedded in the slope ground, so that it can cooperate with the first connecting block 27 to support the cylinder 2, so that the cylinder 2 is off the ground. The position of the first screw rod 28 relative to the first connecting block 27 can be adjusted to adjust the height of the cylinder 2. After the cylinder 2 is fixed to the top of the slope, the screw rod 11 is then rotated forward to make its end leave the inner wall of the circular groove, and the turntable 9 is rotated forward to cooperate with the teeth 10 to drive the gear 8 to rotate forward, thereby driving the rotating rod 4 to rotate forward. The rope 6 is a steel cable, and then the ring plate 7 is pulled to move along the eco-bag 1 to the bottom of the slope. The second screw rod 26 is rotated forward to move relative to the second connecting block 25. The end of the second screw rod 26 is then embedded in the slope so that the ring plate 7 can be supported and fixed. At this time, the bottom of the ring plate 7 leaves the slope. At this time, the rope 6, the ring plate 7, and the cylinder 2 form a whole that wraps the eco-bag 1, so that the eco-bag 1 is supported. Then, soil, fertilizer, and seed mixture are poured into the cylinder 2. The material moves along the slope. As the eco-bag 1 slides down to the bottom of the eco-bag 1, the eco-bag 1 is supported during the sliding process, so the part of the eco-bag 1 without material will not fall into the depression on the slope, causing the material to accumulate in the depression when sliding down and unable to slide smoothly to the bottom of the eco-bag 1, thereby ensuring that the material can slide smoothly to the bottom of the eco-bag 1. As the material is added, after a section is added, the second screw rod 26 is separated from the slope ground, and then the second screw rod 26 is reversed to reset it, and then the turntable 9 is reversed, and vice versa to achieve the reverse rotation of the take-up reel 5. The rope 6 is wound up and the ring plate 7 is moved. When the ring plate 7 moves away from the eco-bag 1 filled with materials, the upper part of the eco-bag 1 filled with materials is tied with an external strap, and then the part of the eco-bag 1 filled with materials is fixed to the slope by an anchor rod. Then the above operation is repeated to lift the position of the ring plate 7, support and fix it to leave the ground. Subsequently, the above operation is repeated to continue pouring materials, and the above operation is repeated until the entire eco-bag 1 is filled and fixed in sections, and finally the eco-bag 1 is filled;

[0052] When the position of the ring plate 7 is adjusted, it moves along the surface of the eco-bag 1. When the ring plate 7 slides along the part of the eco-bag 1 filled with materials, the friction between the ring plate 7 and the eco-bag 1 is large, which causes the ring plate 7 to encounter large resistance when moving, resulting in great difficulty in rotating the turntable 9. Therefore, when the ring plate 7 loses its support and fixation, the part of the eco-bag 1 filled with materials presses down the ring plate 7, causing the bottom plate 23 to conflict with 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 outward. 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 is opened, and the one-way valve 19 in the second channel 18 is closed, and the lubricating oil is squeezed into the circular cavity 13. , and then after the circular cavity 13 is filled, the one-way valve 19 in the nozzle 14 is opened and sprayed onto the eco-bag 1. Then, when the ring plate 7 moves, the ring plate 7 and the eco-bag 1 are lubricated, which greatly reduces the friction, making the pulling of the ring plate 7 easy and convenient for operation. The ball 24 can facilitate the movement of the bottom plate 23 relative to the ground. When the ring plate 7 is lifted and fixed again, the bottom plate 23 leaves the slope. At this time, the spring 22 brings the bottom plate 23 back to its original position, causing the connecting rod 21 and the piston 20 to move and reset accordingly, so that the lubricating oil is replenished into the cavity 15. At this time, the one-way valve 19 in the first channel 17 and the nozzle 14 is closed, and the one-way valve 19 in the second channel 18 is opened, and the lubricating oil in the liquid storage chamber 16 is drawn into the cavity 15 for replenishment.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
