Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a vegetation replanting device for repairing degraded grasslands in arid desert areas. Background Art

[0002] Human factors are the primary cause of grassland degradation in arid desert regions, primarily including overgrazing, overexploitation, and irrational use of water resources. Overgrazing leads to overexploitation of grasslands, inhibiting plant growth and damaging grassland ecosystems. Overexploitation leads to a drop in groundwater levels, soil salinization, and plant growth inhibition. Irrational use of water resources also affects plant growth and development. Restoring degraded sandy grasslands requires replanting. Restoring degraded grasslands in arid desert regions is a complex, systematic project aimed at restoring the ecological functions and productivity of degraded grasslands through a series of measures. Replanting can be done in degraded areas using either spot or patch planting, with the specific method chosen taking into account the extent of vegetation degradation. To increase the success rate of plant establishment, replanting begins by digging a planting hole in the replanting area with a hoe. Then, using a shovel, add soil or nutrient soil brought in by a farm vehicle. A hole is created above the added soil and nutrient soil to facilitate placement of the replant. The replant is placed in the hole and filled with a shovel. After replanting is completed, sand needs to be transported to cover the soil surface. Covering with sand and other covering materials can reduce the loss of water inside the soil, thus helping to increase the seedling establishment rate.

[0003] However, during replanting, the replanting operation steps are complicated and require the cooperation of multiple agricultural tools to complete, which affects the efficiency of replanting. Summary of the Invention

[0004] The purpose of the present invention is to provide a vegetation replanting device for repairing degraded grasslands in arid desert areas, which solves the above problems.

[0005] The technical solution adopted by the present invention is a vegetation replanting device for repairing degraded grasslands in arid desert areas, comprising: Outer protective tube; The planting tube is located inside the outer protective tube and is coaxially arranged with the outer protective tube. Two vertical first partitions are also provided between the outer protective tube and the planting tube. The first partitions divide the cavity between the outer protective tube and the planting tube into a first chamber for temporarily storing nutrient soil and a second chamber for temporarily storing sand and gravel. Two baffles are hinged at the ends of the outer protective tube, and the two baffles form a conical piercing portion when they are aligned. The upper sides of the baffles are respectively provided with discharge ports that communicate with the first chamber and the second chamber; A plurality of stirring shafts are respectively vertically arranged on the lower side of the discharge port of the baffle.

[0006] A baffle plate with the same cross-sectional shape as the second chamber or the first chamber is fixedly provided on the lower end face of the side wall of the planting tube. The planting tube is rotatably arranged on the inner side of the outer protective tube. The first partition is fixedly connected to the inner wall of the outer protective tube, and the first partition is rotatably connected to the outer wall of the planting tube.

[0007] The ends of the plurality of stirring shafts away from the baffle are all pointed.

[0008] A storage cylinder for storing a large amount of nutrient soil and sand is also provided on the outside of the outer protective cylinder. The outer protective cylinder is slidably connected to the storage cylinder and the outer protective cylinder can slide along its axial direction. Two second partitions are also provided between the outer protective cylinder and the storage cylinder. The second partition divides the space between the outer protective cylinder and the storage cylinder into a first storage cavity and a second storage cavity. The first storage cavity is provided corresponding to the first chamber, and the second storage cavity is provided corresponding to the second chamber.

[0009] A first discharge port is provided on the lower side of the inner wall of the storage cylinder, and a second discharge port is provided on the outer wall of the outer protective cylinder. In the initial position, the second discharge port is located on the upper side of the first discharge port shown. When the outer protective cylinder slides down so that the second discharge port corresponds to the first discharge port, the storage cylinder is connected to the first chamber. A third discharge port is also provided on the lower side of the inner wall of the storage cylinder symmetrically arranged with the first discharge port, and a fourth discharge port is provided on the outer wall of the outer protective cylinder.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the protection solutions of the present invention.

[0017] Human factors are the primary cause of grassland degradation in arid desert regions, primarily including overgrazing, overexploitation, and irrational use of water resources. Overgrazing leads to overexploitation of grasslands, inhibiting plant growth and damaging grassland ecosystems. Overexploitation leads to a drop in groundwater levels, soil salinization, and plant growth inhibition. Irrational use of water resources also affects plant growth and development. Restoring degraded sandy grasslands requires replanting. Restoring degraded grasslands in arid desert regions is a complex, systematic project aimed at restoring the ecological functions and productivity of degraded grasslands through a series of measures. Replanting can be done in degraded areas using either spot or patch planting, with the specific method chosen requiring careful consideration of the extent of vegetation degradation. To increase the success rate of plant seedlings, soil or nutrient soil should be added during replanting. After replanting, the soil surface should be covered with a mulch such as sand or gravel. This mulch reduces water loss from the soil, thereby improving the success rate of seedlings.

[0018] However, due to the small operating space during spot planting, it is inconvenient to add covering materials such as nutrient soil and sand to the spot planting.

[0019] The present invention discloses a vegetation replanting device for repairing degraded grasslands in arid desert areas, such as Figure 1-3 As shown, it includes an outer protective tube 1, a planting tube 2, two baffles 12 and a plurality of stirring shafts 6; wherein the planting tube 2 is located on the inner side of the outer protective tube 1 and is coaxially arranged with the outer protective tube 1, and two vertical first partitions 3 are also arranged between the outer protective tube 1 and the planting tube 2. The first partition 3 divides the cavity between the outer protective tube 1 and the planting tube 2 into a first chamber 4 for temporarily storing nutrient soil and a second chamber 5 for temporarily storing sand and gravel; the two baffles 12 are respectively hinged at the ends of the outer protective tube 1, and a conical piercing portion is formed when the two baffles 12 are matched, and the upper side of the baffle 12 is respectively provided with a discharge port connected to the first chamber 4 and the second chamber 5; the plurality of stirring shafts 6 are respectively arranged on the lower side of the discharge port of each baffle 12.

[0020] When using the vegetation replanting device for restoring degraded grasslands disclosed in the present invention, appropriate amounts of nutrient soil and sand are respectively loaded into the first chamber 4 and the second chamber 5, and then the entire device is inserted into the position where replanting is required. While inserting, it is ensured that the first chamber 4 is connected to the discharge port on the corresponding baffle 12, so that the nutrient soil in the first chamber 4 can fall during the insertion process. At this time, the operator rotates the entire replanting device through the handle connected to the outside of the outer protective tube 1, thereby driving the multiple stirring shafts 6 to rotate. The multiple stirring shafts 6 stir the fallen nutrient soil through the spike structure at the end. At the same time, the multiple stirring shafts 6 form a circular groove in the soil during the rotation process, which is convenient for new plants The placement of the two baffles 12 is then controlled to open, and the newly planted crops are placed from the planting tube 2 to complete the crop replanting. After the replanting is complete, the entire device is lifted up and the two baffles 12 are reset. Then, sand can be added to the soil surface through the second chamber 5. The sand that falls on the upper layer can maintain the moisture of the internal soil, which is beneficial to the establishment of crop seedlings. The vegetation replanting device for degraded grassland restoration disclosed by the present invention can complete the addition of nutrient soil, crop replanting and covering of the upper sand layer in a very small space under the protection of the outer protective tube 1 and the drainage action of the first chamber 4 and the second chamber 5. In this process, the surrounding crops can be prevented from affecting the entire replanting process.

[0021] In order to control the process of adding nutrient soil and sand, a baffle plate 7 with the same cross-sectional shape as the second chamber 5 or the first chamber 4 is fixedly provided on the lower end face of the side wall of the planting tube 2 disclosed in this embodiment. The planting tube 2 is rotatably arranged on the inner side of the outer protective tube 1, and the first partition plate 3 is fixedly connected to the inner wall of the outer protective tube 1, and the first partition plate 3 is rotatably connected to the outer wall of the planting tube 2.

[0022] Specifically, a deep groove ball bearing is mounted on the outer wall of the planting tube 2. The outer ring of the deep groove ball bearing is fixed to the first partition 3, while the inner ring has an interference fit with the planting tube. A retaining plate 7 is welded to the bottom end of the planting tube 2. The first partition 3 is welded to the inner wall of the outer protective tube 1. This means that when the planting tube 2 rotates, the first partition 3 and the outer protective tube 1 remain stationary, while the retaining plate 7 rotates with the planting tube 2, sealing either the first chamber 4 or the second chamber 5, respectively. During initial operation, the retaining plate 7 seals the second chamber 5. After the replanting is completed, the planting tube 2 is rotated, and the baffle plate 7 slowly opens the second chamber 5 and slowly closes the first chamber 4 as the planting tube 2 rotates. When the planting tube 2 is rotated 180°, the baffle plate 7 completely opens the bottom of the second chamber 5 and seals the first chamber 4. At this time, the second chamber 5 is connected with the corresponding discharge port on the baffle 12, and the sand can fall into the replanting position through the discharge port, covering the replanting position with sand. Therefore, the first partition 3 and the baffle plate 7 can control the addition process of nutrient soil and sand.

[0023] For ease of operation, multiple stirring shafts 6 are vertically positioned below the discharge port of baffle 12, each with a pointed end away from baffle 12. The vertically positioned ends, marked with arrows, aid in the insertion of the entire replanting device. Furthermore, during the insertion process, as the entire replanting device rotates, the multiple stirring shafts 6 orbit around the central axis of the device, stirring and leveling the fallen nutrient soil to facilitate subsequent crop replanting.

[0024] In order to facilitate the control of the amount of nutrient soil and sand added, the outer side of the outer protective tube 1 disclosed in this embodiment is also provided with a storage tube 11 for storing a large amount of nutrient soil and sand. The outer protective tube 1 is slidably connected to the storage tube 11 and the outer protective tube 1 can slide along its axial direction. Two second partitions 8 are also provided between the outer protective tube 1 and the storage tube 11. The second partitions 8 separate the space between the outer protective tube 1 and the storage tube 11 into a first storage chamber 9 and a second storage chamber 10. The first storage chamber 9 is provided corresponding to the first chamber 4, and the second storage chamber 10 is provided corresponding to the second chamber 5. Therefore, a large amount of nutrient soil and sand can be placed in the first storage chamber 9 and the second storage chamber 10 respectively. During the actual replanting process, an appropriate amount of nutrient soil and sand can be allowed to flow into the first chamber 4 or the second chamber 5 respectively.

[0025] Specifically, a first discharge port is provided on the lower side of the inner wall of the storage cylinder 11, and a second discharge port is provided on the outer wall of the outer protective cylinder 1. In the initial position, the second discharge port is located on the upper side of the first discharge port shown. When the outer protective cylinder 1 slides down so that the second discharge port corresponds to the first discharge port, the storage cylinder 11 is connected to the first chamber 4. A third discharge port corresponding to the first discharge port is also provided on the lower side of the inner wall of the storage cylinder 11, and a fourth discharge port is provided on the outer wall of the outer protective cylinder 1. In the initial position, the fourth discharge port is located on the upper side of the third discharge port. When the outer protective cylinder 1 slides down so that the fourth discharge port corresponds to the third discharge port, the storage cylinder 11 is connected to the second chamber 5.

[0026] Specifically, a longitudinal guide rail, such as a T-shaped or dovetail groove guide rail, is provided on the inner wall of the storage tube 11, and a matching chute is processed at the corresponding position of the outer wall of the outer protective tube 1. Two guide rails and two chute are provided and symmetrically arranged. After completing a replanting, when it is necessary to replenish the nutrient soil and sand in the first chamber 4 and the second chamber 5, the operator pushes the handle on the outer protective tube 1 to move the outer protective tube 1 downward along the longitudinal guide rail, and then aligns the second discharge port with the first discharge port, so that the nutrient soil in the first storage chamber 9 flows into the first chamber 4. After observing the nutrient soil that enters and the nutrient soil is appropriate, the planting tube 2 is rotated to open the first chamber 4 and seal the second chamber 5. The outer protective tube is continued to move downward along the longitudinal guide rail so that the third discharge port is aligned with the fourth discharge port. After the sand in the second storage chamber 10 flows into the second chamber 5, the replenishment of the sand is completed. When it is necessary to fill the sand again, rotate the planting tube 2, and the baffle plate 7 rotates to open the bottom of the second chamber 5 and seal the first chamber 4, so that the sand entering the second chamber 5 flows out from the discharge port of the baffle 12 on the lower side of the second chamber 5 to the replanting position.

[0027] In order to control the discharge of sand and nutrient soil separately and avoid the two processes affecting each other, the height of the fourth discharge port is higher than the second discharge port.

[0028] A handle is further provided on the upper end surface of the storage tube 11 , and a transmission assembly is provided between the handle and the baffles 12 , so that the two baffles 12 can be driven to open and close via the handle.

[0029] The opening and closing methods of the two baffles are universal and there are many methods. The embodiment of the present invention lists one method for illustration. The transmission assembly includes two pulling ropes, the first ends of the two pulling ropes are hinged to the outer walls of the two baffles 12 respectively, and the second ends are connected to the handle.

[0030] Specifically, the upper edge of the baffle 12 is connected to the lower end of the outer protective tube 1 through a hinge.

[0031] When the device is inserted, the handle does not move, and the two baffles 12 close to form a closed conical insertion part. After the nutrient soil is placed and stirred, the handle is pulled, and then the baffles 12 are pulled by the pull rope connected to the handle. The baffles 12 rotate around the hinge and open to both sides, allowing new plants to fall from the opening to complete the replanting.

[0032] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention fall within the protection scope of the present invention.
