Description

Technical Field

[0001] The present invention relates to the technical field of degraded forest restoration, and in particular to a device and method for restoring vegetation in a degraded forest ecosystem. Background Art

[0002] Degraded forest restoration refers to the process of taking appropriate artificial intervention measures to improve the forest structure and habitat, improve the forest quality, and restore and enhance the ecological protection function of degraded forests whose forest ecosystem structure and functions have been damaged due to natural or human factors. The purpose of degraded forest restoration is to restore the ecological function and economic value of degraded forests, mainly including reforestation, replanting, tending and management measures.

[0003] Publication No.: CN111066617A discloses an automatic tree planting machine. The tree planting device provided therein saves labor, reduces the labor intensity of farmers and improves the efficiency of tree planting. The rotary digging device and the conveying device provided therein integrate the three steps of planting seedlings into one. In the process of planting seedlings, the rotary digging device first digs a tree pit for planting the seedlings, and then the seedlings are transported from the conveying device to the tree planting device. Finally, the tree planting device puts the seedlings into the tree pit dug in advance. In the process of planting, the steps of human intervention are reduced, so that the automatic tree planting machine can always maintain a high-efficiency planting speed.

[0004] However, this device has certain drawbacks when in use. In the related art, after the seedlings are half filled with soil during the planting process, the seedlings need to be slightly lifted upwards to ensure that the roots of the seedlings are all facing downwards, which is conducive to the smooth rooting of the seedlings. When the seedlings are half filled with soil, they need to be watered and the filled soil should be watered as much as possible. The purpose of watering is to fix the soil. However, when in use, this device is not convenient for slightly lifting the seedlings after half of the soil is covered, which results in the inability of the roots of the seedlings to all face downwards, which is not conducive to the smooth rooting of the seedlings and reduces the survival rate of the seedlings.

[0005] Therefore, it is necessary to provide a device and method for vegetation restoration in a degraded forest ecosystem to solve the above-mentioned technical problems. Summary of the invention

[0018] A method for restoring vegetation in a degraded forest ecosystem comprises the following steps:

[0019] S1: Restoration Preparation

[0020] First, fill the water tank with water, and then place the seedlings to be moved in the storage box. When placing the seedlings, the roots of the seedlings are placed at the bottom of the inner wall of the storage box, and the seedlings are leaning against the storage box in an inclined state. Finally, connect the device to the traction equipment through the traction frame, and move the device to the area where replanting is required through the traction equipment;

[0021] S2: Pit excavation work

[0022] First, determine the specific location where replanting and replanting are required, and then measure the spacing between the transplanted saplings. After the measurement, use the traction equipment to pull the device to the working position so that the bottom of the threaded hole-opening piece is located at the top of the hole-opening position, and then start the hole-opening motor. The hole-opening motor drives the rotating shaft and the threaded hole-opening piece to rotate slowly. During the rotation of the threaded hole-opening piece, the lead screw lifting device is started, and the lead screw lifting device drives the threaded hole-opening piece to rotate downward to open the hole. The hole-opening depth can be 20-30 cm more than the original tree root depth. After the hole-opening is completed, turn off the hole-opening motor, and drive the rotating shaft and the threaded hole-opening piece to move upward through the lead screw lifting device;

[0023] S3: Planting work

[0024] S31: After the pit is opened, the traction device drives the device to move forward, so that the positions of the through holes on the inner side of the frame and the mounting plate are parallel to the upper and lower sides of the planting pit, and then the second hydraulic rod is started, and the second hydraulic rod drives the mounting plate to move downward, so that the soil covering frame contacts the ground. During the process of the soil covering frame contacting the ground downward, the vertical clamping mechanism will actively move downward under the influence of the moving plate, and then the roots of the saplings are manually placed in the planting pit, so that the saplings are in a vertical state, and the third hydraulic rod is started, and the third hydraulic rod retracts to drive the two clamping frames to move to the opposite side, so as to clamp the saplings;

[0025] S32: Start the first hydraulic rod, and the first hydraulic rod retracts to drive the soil covering frame to move forward, so as to push the soil generated by the hole opened on the half ground into the planting pit to cover the roots of the saplings. During the forward movement of the soil covering frame, the two movable plates are simultaneously driven to move forward, and the two movable plates move forward to lift the vertical clamping mechanism and the sapling upward, so that the roots of the saplings can face downward;

[0026] S33: After the second hydraulic rod drives the mounting plate to move downward, the first hydraulic rod drives the two movable plates to move forward through the soil covering frame. The two movable plates drive the two push blocks to move forward. The movement of the two push blocks drives the two rotating valves to rotate. After the rotating valves rotate, the water in the water tank flows from the water outlet pipe into the planting pit. After watering is completed, the first hydraulic rod is controlled to reset the position of the soil covering frame.

[0027] S4: Soil compaction work

[0028] After watering the saplings, the clamping of the saplings is cancelled by controlling the third hydraulic rod. After the clamping is cancelled, the workers simply support the saplings with their hands, and then drive the device forward through the traction equipment. When the device moves forward, the covering plate and the soil pressing wheel move backward. The movement of the covering plate pushes the other half of the soil into the planting pit, and the soil is compacted by the movement of the soil pressing wheel to expel the air in the soil. When the tail of the device moves beyond the planting pit, the position of the mounting plate can be reset by the second hydraulic rod.

[0029] Compared with the related art, the equipment and method for vegetation restoration of degraded forest ecosystem provided by the present invention have the following beneficial effects:

[0030] The soil covering frame and the movable plate are driven to move forward by retracting the first hydraulic rod, so that the soil covering frame is used to push the soil generated by the pit opened on the ground into the planting pit. In the process of the soil covering frame moving forward, the two movable plates are driven to move forward, and the movement of the two movable plates drives the rollers and the rotating support frame to move upward, so that the mounting frame drives the clamping frame and the sapling to move upward, thereby slightly lifting the sapling so that the root of the sapling faces downward, and when the soil covering frame drives the movable plate to move forward to a certain position, the movable plate drives the two pushing blocks to push the two rotating valves, thereby watering the planting pit. The structure is exquisite, and when covering the planting pit with soil, the sapling can be slightly lifted upward so that the root of the sapling faces downward, and the roots of the sapling can be watered at the same time, so that the roots of the sapling can fully absorb water, which is conducive to the smooth rooting of the sapling and improves the survival rate of the sapling transfer.

[0075] Please combine Figures 14 to 16 : Start the two driving motors 53. The rotation of the two driving motors 53 can drive the two threaded screws 51 to rotate. The rotation of the two threaded screws 51 can drive the two covering plates 52 to move to the opposite side, so that the working positions of the two covering plates 52 can be adjusted according to the diameter of the sapling;

[0076] Furthermore, after watering the saplings, the clamping of the saplings by the clamping frame 33 is cancelled, the saplings are straightened manually, and the first hydraulic rod 25 is started. The first hydraulic rod 25 is extended to drive the covering frame 26 and the movable plate 28 to move backward, and then the device is driven forward by the traction equipment. When the device moves forward, the two covering plates 52 will move backward, thereby pushing the other half of the soil on the ground into the planting pit.

[0077] A soil pressing mechanism 6 is fixedly provided at the front side of the bottom of the mounting plate 21. The soil pressing mechanism 6 includes two rotating frames 61 fixedly provided at the front side of the bottom of the mounting plate 21.

A scraper plate 64 is fixedly provided at the front sides of the two covering plates 52.

[0078] Please combine Figures 14 to 16 : When the device is driven forward by the traction equipment, the two soil pressing wheels 63 will move backward, and then the soil in the planting pit is scraped by the two soil covering plates 52 to be compacted, and the air in the soil is discharged, so that the saplings can take root. In addition, due to watering the planting pit, the soil near the planting pit will become moist. In the process of compacting the soil by the soil pressing wheel 63, part of the moist soil will stick to the soil pressing wheel 63. The setting of the scraper plate 64 can remove the moist soil stuck on the surface of the soil pressing wheel 63;

[0079] Furthermore, when the other half of the soil on the ground is pushed into the planting pit by the covering plate 52 and the soil is compacted by the soil pressing wheel 63, the second hydraulic rod 29 is started, and the mounting plate 21 is moved upward by the retraction of the second hydraulic rod 29, thereby resetting the device.

[0080] The inner sides of the two covering plates 52 are respectively provided with thread grooves used in cooperation with the two threaded screw rods 51 , and the two covering plates 52 are in an arc shape.

[0081] In this embodiment, when the device is driven forward by the traction equipment, the two covering plates 52 and the two pressing wheels 63 will move backward at the same time, and the other half of the soil on the ground will be pushed into the planting pit through the movement of the two covering plates 52. The soil pushed into the planting pit can be automatically compacted and the air in the soil can be discharged through the movement of the two pressing wheels 63. No manual labor and operation are required during the covering and pressing process, which effectively reduces the manual workload.

[0084] Please combine Fig.17 : Start the hole-digging motor 75, and the rotation of the hole-digging motor 75 will drive the rotating shaft 73 to rotate, and the rotation of the rotating shaft 73 will drive the threaded hole-digging member 74 to rotate. The use height position of the threaded hole-digging member 74 can be controlled and adjusted through the screw lifting device 71, and the hole in the ground can be dug through the rotation of the threaded hole-digging member 74.

[0085] Two storage boxes 8 are arranged on the front side of the top of the frame 1, two traction frames 9 are arranged on the rear side of the top of the frame 1, and four wheels 10 are rotatably connected to the bottom of the frame 1;

[0086] Preferably, air holes are provided on the inner sides of the bottoms of the two storage boxes 8, through which the roots of the seedlings can be ventilated, thereby improving the survival rate of the seedlings after planting. The two traction frames 9 are provided for connecting with external traction equipment.

[0087] In this embodiment, the rotation of the hole-digging motor 75 will drive the rotating shaft 73 to rotate, and the rotation of the rotating shaft 73 will in turn drive the threaded hole-digging member 74 to rotate. The use height position of the threaded hole-digging member 74 can be controlled and adjusted by the screw lifting device 71. The rotation of the threaded hole-digging member 74 is used to dig a hole in the ground, and the depth of the hole can be freely controlled. Compared with traditional manual hole digging, the efficiency of transferring saplings is improved.

[0088] Please refer to Figures 1 to 17 The working principle of the equipment for vegetation restoration of degraded forest ecosystem provided by the present invention is as follows:

[0089] Step S1, first fill the water tank 42 with water, then place the saplings to be transferred in the storage box 8, move the device to the position where the transfer is required by the traction equipment, and after determining the position of the planting pit, start the pit opening motor 75, and drive the rotating shaft 73 and the threaded pit opening member 74 to rotate slowly by the pit opening motor 75. The threaded pit opening member 74 starts the screw lifting device 71 during the rotation process, and drives the screw lifting device 71 to drive the threaded pit opening member 74 to rotate downward to open the pit, and the soil after the pit opening will remain at the edge of the planting pit;

[0090] Step S2, the device is driven forward by the traction equipment to make the position of the circular through hole inside the frame 1 and the mounting plate 21 parallel to the planting pit, and then the second hydraulic rod 29 is started, and the second hydraulic rod 29 drives the mounting plate 21 to move downward. When the mounting plate 21 moves downward, it drives the covering frame 26 and the movable plate 28 to move downward, so that the bottom of the covering frame 26 contacts the ground. In the process of the covering frame 26 contacting the ground downward, the vertical clamping mechanism 3 will actively move downward under the influence of the movable plate 28, and then the sapling is placed on the opposite side of the two clamping frames 33, and the two third hydraulic rods 34 are started. The retraction of the two third hydraulic rods 34 drives the two movable frames 32 to slide on the surface of the mounting frame 31 to the opposite side. During the sliding process, the two mounting frames 31 will drive the two gear plates 37 to move to the opposite side, thereby causing the gear 36 to rotate. Through the movement of the two movable frames 32, the two clamping frames 33 are driven to move to the opposite side, thereby clamping and straightening the sapling;

[0091] Step S3, start the first hydraulic rod 25, and drive the soil covering frame 26 and the movable plate 28 to move forward through the retraction of the first hydraulic rod 25, so that the soil on the ground can be pushed into the planting pit. When the soil covering frame 26 and the movable plate 28 move forward, the roller 311 and the rotating support frame 310 are lifted upward through the movement of the movable plate 28, and the installation frame 31, the clamping frame 33 and the sapling are driven to move upward through the movement of the rotating support frame 310, so that the sapling can be slightly lifted upward during the process of covering the planting pit with soil, and when the soil covering frame 26 and the movable plate 28 move forward, the two movable plates 28 move forward to drive the two push blocks 47 to move forward, and the two push blocks 47 move forward to push the two rotating valves 44 to rotate, and the two return springs 45 are stretched, and the two water outlet pipes 43 are opened through the rotation of the two rotating valves 44, and water is discharged into the planting pit through the two water outlet pipes 43;

[0092] Step S4, when the watering of the saplings is completed, the clamping of the saplings by the clamping frame 33 is cancelled by extending the two third hydraulic rods 34, and then the saplings are manually straightened, and the first hydraulic rod 25 is started, and the soil covering frame 26 and the movable plate 28 are driven to move backward by extending the first hydraulic rod 25. During the movement of the movable plate 28 backward, under the action of the return spring 45, the rotating valve 44 is closed to stop watering the planting pit, and when the movable plate 28 moves backward, under the action of the roller 311 and the rotating support frame 310, the mounting frame 31 drives the movable frame 32 and the clamping frame 33 to move downward, so that the sliding seat 38 slides downward on the surface of the slide rail 39, and then the device is driven to move forward by the traction device;

[0093] Step S5, when the device moves forward, the two covering plates 52 and the two pressing wheels 63 will move backward, and the other half of the soil on the ground will be pushed into the planting pit through the movement of the two covering plates 52. The soil pushed into the planting pit can be automatically compacted and the air in the soil can be discharged through the movement of the two pressing wheels 63. After completing the covering and compacting of the planting pit, the second hydraulic rod 29 is started, and the mounting plate 21 is driven to move upward by the retraction of the second hydraulic rod 29, thereby resetting the device and completing the transfer of the saplings.

[0094] Please refer to Figures 1 to 17 , a method for vegetation restoration of a degraded forest ecosystem, comprising the following steps:

[0095] S1: Restoration Preparation

[0096] First, fill the water tank 42 with water, and then place the seedlings to be moved in the storage box 8. When placing the seedlings, the roots of the seedlings are placed at the bottom of the inner wall of the storage box 8, and the seedlings are leaning against the storage box 8 in an inclined state. Finally, the device is connected to the traction equipment through the traction frame 9, and the device is moved to the area where replanting is required through the traction equipment;

[0097] S2: Pit excavation work

[0098] First, determine the specific location where replanting and replanting are required, and then measure the spacing between the transplanted saplings. After the measurement, use the traction equipment to pull the device to the working position so that the bottom of the threaded hole-opening member 74 is located at the top of the hole-opening position, and then start the hole-opening motor 75. The hole-opening motor 75 drives the rotating shaft 73 and the threaded hole-opening member 74 to rotate slowly. During the rotation of the threaded hole-opening member 74, the screw lifting device 71 is started. The screw lifting device 71 drives the threaded hole-opening member 74 to rotate downward to open the hole. The hole-opening depth can be 20-30 cm more than the original tree root depth. After the hole-opening is completed, turn off the hole-opening motor 75, and drive the rotating shaft 73 and the threaded hole-opening member 74 to move upward through the screw lifting device 71;

[0099] S3: Planting work

[0100] S31: After the pit is opened, the traction device drives the device to move forward, so that the positions of the inner through holes of the frame 1 and the mounting plate 21 are parallel to the upper and lower sides of the planting pit, and then the second hydraulic rod 29 is started, and the second hydraulic rod 29 drives the mounting plate 21 to move downward, so that the soil covering frame 26 contacts the ground. During the process of the soil covering frame 26 contacting the ground downward, the vertical clamping mechanism 3 will actively move downward under the influence of the moving plate 28, and then the roots of the saplings are manually placed in the planting pit to make the saplings in a vertical state, and the third hydraulic rod 34 is started, and the third hydraulic rod 34 retracts to drive the two clamping frames 33 to move to the opposite side, so as to clamp the saplings;

[0101] S32: Start the first hydraulic rod 25, which retracts to drive the soil covering frame 26 to move forward, so as to push the soil generated by the hole on the half ground into the planting pit to cover the roots of the saplings. The soil covering frame 26 will simultaneously drive the two moving plates 28 to move forward during the forward movement. The two moving plates 28 move forward to lift the vertical clamping mechanism 3 and the sapling upwards. This process can make the roots of the saplings face downwards.

[0102] S33: After the second hydraulic rod 29 drives the mounting plate 21 to move downward, the first hydraulic rod 25 drives the two movable plates 28 to move forward through the soil covering frame 26. The two movable plates 28 drive the two push blocks 47 to move forward. The movement of the two push blocks 47 drives the two rotating valves 44 to rotate. After the rotating valves 44 rotate, the water in the water tank 42 flows into the planting pit from the water outlet pipe 43. After watering is completed, the first hydraulic rod 25 is controlled to reset the position of the soil covering frame 26.

[0103] S4: Soil compaction work

[0104] After watering the saplings, the clamping of the saplings is cancelled by controlling the third hydraulic rod 34. After the clamping is cancelled, the workers simply support the saplings with their hands, and then drive the device forward by the traction equipment. When the device moves forward, the covering plate 52 and the soil pressing wheel 63 move backward. The movement of the covering plate 52 pushes the other half of the soil into the planting pit, and the movement of the soil pressing wheel 63 compacts the soil and discharges the air in the soil. When the rear end of the device moves beyond the planting pit, the position of the mounting plate 21 can be reset by the second hydraulic rod 29.
