Description

Technical Field

[0001] The present invention relates to the field of gardening technology, and particularly relates to a tree planting device for land ecological restoration. Background Art

[0002] Trees absorb carbon dioxide and release oxygen through photosynthesis. For example, an adult big tree can absorb about 22 kilograms of carbon dioxide every year, which helps to reduce the content of greenhouse gases in the atmosphere and alleviate the trend of global warming. Trees can also adsorb pollutants such as dust, pollen, and smoke in the air, playing a role in purifying the air. The roots of trees can fix the soil and prevent soil erosion. Especially in mountainous areas, the roots of trees hold the soil tightly like a big net, preventing the soil from being washed away by rainwater. Trees can also slow down the speed of surface runoff, enabling more rainwater to infiltrate into the ground, replenishing groundwater resources, and reducing the occurrence of flood disasters; trees can also provide other forest products, such as resin, rubber, fruits, etc. Among them, when fruit trees are planted, bare-root seedlings with root and stem pruning are usually used to reduce the water evaporation and nutrient consumption of the plants, so that the plants can adapt to the new environment faster after transplantation and improve the survival rate.

[0003] The Chinese patent application with the publication number CN215012221U discloses a gardening tree planting auxiliary device, including a pit digging mechanism and a tree planting mechanism. The pit digging mechanism includes a first support frame with universal wheels fixed at the bottom, first arc-shaped plates fixed on both sides of the first support frame, an adjustment component arranged inside the pit digging mechanism and the tree planting mechanism, a support seat, a motor fixed on the top of the support seat, and a spiral blade fixed at the bottom end of the output shaft of the motor through a coupling. The adjustment component includes a servo motor fixed on the top of the first support frame, a threaded rod fixed at the bottom end of the output shaft of the servo motor through a coupling, and a slider slidably matched with the inner wall of the first support frame. The tree planting mechanism includes a second support frame with universal wheels fixed at the bottom, second arc-shaped plates fixed on both sides of the second support frame, a connecting rod rotatably matched with the slider through a pin, a support column fixed at one end of the connecting rod, mounting frames symmetrically fixed on one side of the support column, clamping blocks slidably matched with the inner wall of the mounting frames, a bidirectional screw rod fixed on the inner walls of both sides of the mounting frames through bearings, and a crank fixed at one end of the bidirectional screw rod.

[0004] In the implementation process of the above technical solution, first, the first arc-shaped plate and the second arc-shaped plate are fixed by bolts to form a planting auxiliary device. Subsequently, the connecting rod, the support rod, and the bottom plate are rotated to perform secondary support on the first arc-shaped plate and the second arc-shaped plate to improve the stability of the device. Then, the support seat is rotated and the screw rod is driven to rotate by the servo motor, so that the motor and the spiral blade can move downward to dig a hole. After the hole digging is completed, the crank is rotated to clamp and fix the sapling between the clamping blocks. Then, by rotating the connecting rod, the sapling is placed in the hole by using the adjusting assembly, which can avoid the sapling from tilting and lodging. However, this planting process requires operating the crank to fix the sapling, which is rather inconvenient. Moreover, it takes a lot of time to support the first arc-shaped plate and the second arc-shaped plate during the tree planting process, which is time-consuming and laborious. After the sapling is placed in the tree pit, manual backfilling of soil is still required, so it is not convenient for efficient planting. Summary of the Invention

[0005] The present invention provides a tree planting device for land ecological restoration, aiming to solve the problems in the related art that it is difficult to efficiently plant saplings and improve the survival rate of saplings.

[0006] A tree planting device for land ecological restoration includes a top seat. A telescopic cylinder is provided at the bottom of the top seat. A ring cylinder is rotatably provided at the bottom of the top seat inside the telescopic cylinder. There is a feeding channel between the inner side of the telescopic cylinder and the outer side of the ring cylinder. There is a discharging channel inside the ring cylinder. A conveying member is provided on the outer side of the ring cylinder. A plurality of soil drilling members are rotatably provided at the bottom of the ring cylinder through an elastic member I. A planting cylinder that can move up and down is rotatably provided inside the ring cylinder. The planting cylinder is connected to the top seat through an elastic member II. A pressing member that can move up and down is provided inside the top seat. A motor for driving the ring cylinder and the planting cylinder to rotate synchronously in opposite directions is installed inside the top seat. When the motor rotates forward, a plurality of soil drilling members can drill holes in the ground, and the conveying member can convey the drilled soil to the discharging channel through the feeding channel. When the telescopic cylinder contracts, it can drive the pressing member to move downward, so that the planting cylinder downwardly abuts against a plurality of soil drilling members, and the plurality of soil drilling members can turn outwards and open, so that the sapling in the planting cylinder can fall to the ground. When the telescopic cylinder extends and resets, a plurality of soil drilling members can turn inwards, close and form an inverted conical structure.

[0007] Through continuous downward excavation by the soil drilling members of the present invention, the soil can be conveyed to the discharging channel. When the soil drilling members excavate to a predetermined depth, the sapling can fall from the planting cylinder. At the same time, the soil in the discharging channel can timely cover the root of the sapling.

[0008] Preferably, the conveying member is a spiral blade fixedly provided on the outer peripheral side of the ring cylinder. The setting of the spiral blade facilitates conveying the soil drilled by the soil drilling members to the discharging channel.

[0009] Preferably, a plurality of stirring rods are provided along the axial direction on the outer peripheral side of the planting tube. The setting of the stirring rods facilitates the crushing and stirring of the soil in the feeding channel, so that after the soil in the feeding channel covers the roots of the seedlings, it can contact the roots of the seedlings more closely, thereby facilitating the survival of the seedlings.

[0010] Preferably, a support member is coaxially fixedly provided at the bottom of the annular cylinder, an auxiliary plate is fixedly provided on the support member, and the soil drilling member is slidably connected to the auxiliary plate.

[0011] Preferably, the first elastic member is a torsion spring.

[0012] Preferably, the inner side of the soil boring member has a top plate that cooperates with the planting tube, and the outer side surface of the soil boring member has cutting teeth.

[0013] Preferably, a through hole is provided on the top of the annular cylinder for soil to enter the lower material channel through the upper material channel.

[0014] Preferably, the telescopic cylinder comprises an upper cylinder, a middle cylinder and a lower cylinder which are slidably connected in sequence, the upper cylinder is fixedly connected to the top seat, and the radii of the upper cylinder, the middle cylinder and the lower cylinder decrease in sequence.

[0015] Preferably, a rack 1 is slidably provided in the top seat, and a rack 2 cooperating with the rack 1 is provided on the pressing piece. When the middle tube stops upward against the rack 1, the rack 1 can drive the pressing piece downward through the rack 2, so that when the drilling piece is excavated to a predetermined depth, the pressing piece can drive the planting tube to move downward to open the multiple drilling pieces.

[0016] Preferably, a driving member is rotatably provided inside the top seat, the planting cylinder is coaxially slidably connected with the driving member, a gear one cooperating with the motor is installed on the outer periphery of the driving member, a gear ring is coaxially provided on the top of the ring cylinder, a gear three meshing with the gear ring is rotatably provided inside the ring cylinder, and a gear two meshing with the gear three is installed on the outer periphery of the driving member, so that when the motor rotates, the planting cylinder and the ring cylinder can rotate at the same time, so as to facilitate excavation and stirring at the same time.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. As the drilling piece continues to dig downward, when the lower cylinder drives the middle cylinder to move upward relative to the upper cylinder, so that when the middle cylinder stops against the sliding rod upward, multiple drilling pieces can flip outward and open. At this time, the motor is controlled to stop, and the top seat is lifted up a distance by the handle. The top plate is separated from the blockage of the bottom of the planting cylinder. The soil in the feeding channel squeezes the drilling piece under the action of gravity so that multiple drilling pieces remain in a state of flipping outward and opening. Then the sapling can fall from the planting cylinder and contact the bottom of the pit. The soil in the feeding channel will fall immediately and cover the roots of the sapling. Then the equipment is completely lifted out of the pit. In this process, the soil in the feeding channel can be automatically backfilled into the pit, thereby realizing the planting of the sapling. The operation is convenient and efficient.

[0018] 2. Due to the accumulation of plant residues, microbial activities, and organic fertilizers in the topmost layer of the ground soil, the organic matter content is significantly higher than that of the deeper layers. Therefore, during the planting process, since the soil at the bottommost layer of the feeding channel is the topmost layer of the ground soil, and this part of the soil first comes into contact with the roots of the saplings, the survival rate of the saplings is greatly improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The embodiments of the present invention will be described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] Reference Figures 1 - 3 Figures 1 - 3 , a tree-planting device for land ecological restoration, includes a top seat 10. A handle 15 is fixedly installed on the outer side of the top seat 10. A telescopic cylinder is provided at the bottom of the top seat 10. The telescopic cylinder includes an upper cylinder 23, a middle cylinder 24, and a lower cylinder 25 that are coaxially and slidably connected in sequence. The upper cylinder 23 is fixedly connected to the top seat 10. The radii of the upper cylinder 23, the middle cylinder 24, and the lower cylinder 25 decrease in sequence. In this embodiment, a first limiting groove 241 is vertically formed on the inner wall of the middle cylinder 24. A first limiting block 251 that cooperates with the first limiting groove 241 is provided on the outer side of the top of the lower cylinder 25. A second limiting groove 231 is vertically formed on the inner wall of the upper cylinder 23. A second limiting block 242 that cooperates with the second limiting groove 231 is provided on the outer side of the top of the middle cylinder 24.

[0030] Reference Figures 2 - 6 And Figure 8 Figure 8 , a ring cylinder 20 is rotatably provided at the bottom of the top seat 10 on the inner ring side of the telescopic cylinder. There is a feeding channel between the inner ring side of the telescopic cylinder and the outer ring side of the ring cylinder 20. The inner ring side of the ring cylinder 20 has a discharging channel. A plurality of through holes 201 for soil to enter the discharging channel through the feeding channel are formed on the outer periphery of the top of the ring cylinder 20. A conveying member 21 is provided on the outer side of the ring cylinder 20. The conveying member 21 is a spiral blade fixedly installed on the outer peripheral side of the ring cylinder 20. The top end of the spiral blade cooperates with one of the through holes 201, and a guide plate 211 is provided at the top end of the spiral blade; A plurality of soil drilling members 30 are rotatably provided at the bottom of the ring cylinder 20 through a first elastic member. The first elastic member uses a torsion spring. In this embodiment, there are three soil drilling members 30. When the three soil drilling members 30 are closed, they form an inverted conical structure. Cutting teeth 302 are provided on the outer side surface of the soil drilling member 30. Therefore, when the ring cylinder 20 rotates, the soil drilling member 30 can accelerate the soil drilling process through the cutting teeth 302. The drilled soil can be upwardly conveyed in the feeding channel by the spiral blade and smoothly enter the discharging channel through the through hole 201 with the assistance of the guide plate 211. It can be understood that under the action of the continuous downward feeding of the soil drilling member 30 into the soil, the soil drilling member 30 will generate extrusion with the ground soil, and then drive the soil broken by the soil drilling member 30 to move upward in the feeding channel.

[0031] Since the soil drilling member 30 first contacts the surface soil, the surface soil has lower adhesiveness compared to the deep soil. Moreover, the present invention is directed to the tree-planting environment for ecological restoration, and the soil adhesiveness is very low. Additionally, considering the actual situation, during the process of the soil drilling member 30 drilling down into the soil, the entire device will continuously vibrate and shake. When the surface soil initially drilled by the soil drilling member 30 is being conveyed upward by the conveying member 21 in the feeding channel, when the upper end of the soil in the feeding channel crosses the lower edge of the through hole 201, since the through hole 201 cannot support the soil, the soil in the feeding channel will surely flow into the through hole 201 and enter the discharging channel under the action of its own weight, the vibration and shaking of the entire device, and the upward acting force of the conveying member 21.

[0032] A planting cylinder 40 that can move up and down is rotatably provided inside the annular cylinder 20. The planting cylinder 40 is connected to the top seat 10 through an elastic member two 401. The elastic member two 401 is a spring. A feeding hopper 14 for assisting in placing the sapling into the planting cylinder 40 is provided at the top of the top seat 10. A plurality of stirring rods 402 are provided on the outer peripheral side of the planting cylinder 40 along its axial direction. When the planting cylinder 40 rotates, the stirring rods 402 can break and stir the soil in the discharging channel, so that after the soil in the discharging channel covers the root of the sapling, it can contact the root of the sapling more closely, thereby facilitating the survival of the sapling.

[0033] A support member 22 is coaxially and fixedly provided at the bottom of the annular cylinder 20. The annular cylinder 20 is coaxially and slidably connected to the support member 22. An auxiliary plate 221 that cooperates with the soil drilling member 30 is fixedly provided on the support member 22. The inner side of the soil drilling member 30 has a top plate 301 that cooperates with the planting cylinder 40. The soil drilling member 30 is slidably connected to the auxiliary plate 221 through the top plate 301. The setting of the auxiliary plate 221 can strengthen the support for the soil drilling member 30, so that the annular cylinder 20 can drive the soil drilling member 30 to rotate stably.

[0034] A pressing member 41 that can move up and down is provided inside the top seat 10. Two sliding rods 121 are slidably provided inside the top seat 10 along the vertical direction. The two sliding rods 121 are symmetrically arranged with respect to the planting cylinder 40. Both sliding rods 121 are located on the inner ring side of the upper cylinder 23 and can abut against the upper end of the middle cylinder 24. A first rack 12 is fixedly provided at the upper end of the sliding rod 121. The pressing member 41 has a second rack 411 that cooperates with the two first racks 12 one by one. Taking one of the first racks 12 and the second rack 411 as an example, a transmission gear 16 that meshes with the first rack 12 and the second rack 411 is rotatably provided inside the top seat 10. Therefore, when the middle cylinder 24 abuts against the sliding rod 121 upward, the first rack 12 can drive the pressing member 41 to move downward through the second rack 411, and further enable the pressing member 41 to drive the planting cylinder 40 to move downward. When the planting cylinder 40 moves downward, it can abut against the top plate 301, so that a plurality of soil drilling members 30 can turn outward and open.

[0035] Reference Figures 2 - 7, a motor 11 for driving the ring cylinder 20 and the planting cylinder 40 to rotate synchronously and in opposite directions is installed inside the top seat 10. In this embodiment, a driving member 13 is rotatably provided inside the top seat 10. The planting cylinder 40 is located on the inner ring side of the driving member 13 and is coaxially and slidably connected to the driving member 13. A chute 403 is provided on the outer side of the planting cylinder 40 in the vertical direction. A slider 133 that cooperates with the chute 403 is fixedly provided on the inner ring side of the driving member 13. A first gear 131 is installed on the outer circumference of the driving member 13. The output end of the motor 11 is installed with a driving gear 111 that meshes with the first gear 131. A toothed ring 202 is coaxially fixed at the top of the ring cylinder 20. A third gear 203 that meshes with the toothed ring 202 is rotatably provided inside the ring cylinder 20. A second gear 132 that meshes with the third gear 203 is installed on the outer circumference of the driving member 13. The third gear 203 is located between the inner ring side of the toothed ring 202 and the outer side of the second gear 132. Therefore, when the motor 11 rotates, it can drive the ring cylinder 20 and the planting cylinder 40 to rotate synchronously and in opposite directions.

[0036] Specific working principle: Refer to Figures 1 - 8 , in the initial state, the telescopic cylinder is in the extended state, the second elastic member 401 is in the state of pushing the planting cylinder 40 upward, the soil drilling member 30 is closed under the action of the first elastic member and presents an inverted conical structure, and the top plate 301 seals the bottom of the planting cylinder 40.

[0037] When in use, first place the bare-root seedlings after root and stem pruning in the hopper 14, so that the saplings enter the planting cylinder 40 through the hopper 14. At this time, since the top plate 301 seals the bottom of the planting cylinder 40, the saplings will stay in the planting cylinder 40 temporarily. Then hold the handle 15 and control the motor 11 to rotate forward. During this process, multiple soil drilling members 30 first contact the ground. As the soil drilling members 30 dig downward, the lower cylinder 25 will abut against the ground and move upward relative to the middle cylinder 24, so that the telescopic cylinder begins to gradually contract. The soil drilled out by the soil drilling members 30 can be conveyed upward through the spiral blades in the feeding channel and enter the discharging channel through the through hole 201. The soil will be broken and stirred by the stirring rod 402 during the falling process in the discharging channel, so that the soil particles become smaller. It can be understood that the soil drilled out by the soil drilling members 30 can be retained in the space enclosed by the inner side of the ring cylinder 20 and the multiple soil drilling members 30. It can be understood that the soil at the lowest layer in the discharging channel is the topsoil on the ground surface.

[0038] As the soil drilling member 30 continuously advances downward, when the lower cylinder 25 drives the middle cylinder 24 to move upward relative to the upper cylinder 23 so that the middle cylinder 24 abuts against the slide bar 121 upward, the multiple soil drilling members 30 can turn outward and open. When the multiple soil drilling members 30 turn outward and open, the multiple soil drilling members can enclose a space in the shape of an approximate cylinder or inverted frustum. The soil moving downward will fill the above space, and the soil in the above space can support the multiple soil drilling members 30 to keep them in an open state. At this time, control the motor 11 to stop rotating, and lift the top seat 10 by a certain distance through the handle 15, so that the top plate 301 is separated from the bottom of the planting cylinder 40. The soil in the feeding channel is extruded under the action of gravity to make the multiple soil drilling members 30 keep turning outward and open. When the top seat 10 is lifted by a certain distance through the handle 15, under the supporting action of the soil in the space formed between the multiple soil drilling members, the multiple soil drilling members 30 will not immediately close inward. When the multiple soil drilling members 30 turn outward and open, the top plate 301 will also turn downward and open the bottom of the planting cylinder 40. Since only saplings are stored inside the planting cylinder 40, after the top plate 301 is opened, the saplings in the planting cylinder 40 will move downward and the roots of the saplings will protrude downward from the bottom of the planting cylinder 40. At this time, there is more soil inside the feeding channel. Besides existing in the space corresponding to the multiple soil drilling members 30, it also exists in the space between the outer wall of the planting cylinder 40 and the inner wall of the annular cylinder 20. Moreover, since the space formed by the multiple soil drilling members 30 is small, the amount of soil existing in the space between the outer wall of the planting cylinder 40 and the inner wall of the annular cylinder 20 is much larger than the amount of soil in the space formed by the multiple soil drilling members 30. As the soil and saplings move downward, a large amount of the soil in the space between the outer wall of the planting cylinder 40 and the inner wall of the annular cylinder 20 can only cover downward after the saplings fall. Subsequently, the device is completely lifted out of the soil pit. During this process, the soil in the feeding channel can automatically backfill into the soil pit, thereby realizing the planting of saplings, and the operation is convenient and efficient.

[0039] It can be understood that during the process of the soil existing in the space between the outer wall of the planting cylinder 40 and the inner wall of the annular cylinder 20 moving downward, due to the large amount of this part of the soil, this part of the soil will accumulate at the roots of the saplings and thus generate a downward driving force on the tree roots, so that the saplings move downward and the planting is completed.

[0040] The planting device of the present application is a small device operated by a single person and will not be used to plant large seedlings, but only to plant smaller saplings, and their root systems are smaller after being pruned.

[0041] The organic matter content of the topsoil on the ground is significantly higher than that of the deep layer due to the accumulation of plant residues, microbial activities and organic fertilizers. Therefore, during the planting process, since the soil at the bottom layer of the feeding channel is the topsoil on the ground and this part of the soil first contacts the roots of the saplings, the survival rate of the saplings is greatly improved.

[0042] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
