Description

Technical Field

[0001] The present invention relates to the field of desert tree planting, and specifically to a fully automatic desert tree planting device. Background Art

[0002] In desertification control projects, constructing a vegetation edge-locking belt is a key technical means to contain the spread of drifting sand. The current operation mode has the following technical bottlenecks: Defects of traditional manual planting: Relying on manual labor to complete processes such as digging pits, planting, and covering soil, there are problems of high labor intensity and a mismatch between the operation efficiency and the scale of desert control. A typical desert edge-locking project needs to be continuously implemented for several years to form a stable ecological barrier.

[0003] Limitations of existing automated equipment: Defects in the soil covering process: Some tree planters mostly use the method of wheel body rolling or mechanical arm one-way soil pushing to complete soil covering, resulting in uneven backfilling of the soil body and unable to form an effective water storage structure.

[0004] Lack of tree pit structure: The seedling insertion device does not construct a concave tree pit with a water storage function, directly resulting in the loss of irrigation water.

[0005] Problems in process connection: Most equipment executes digging pits, planting, and covering soil as discrete processes, lacking coordinated operation control, resulting in an increase in the soil disturbance rate and affecting root colonization.

[0006] When the soil covering density is low and the water storage volume of the tree pit does not meet the standard, the survival rate of typical sand-fixing plants such as Haloxylon ammodendron will decline. The soil covering density directly affects the water retention capacity of the soil and root development. Too low a density will cause the soil to be loose, accelerate water evaporation, and make it difficult for roots to be fixed. Especially in arid sandy areas, insufficient water retention capacity will exacerbate plant water shortage; insufficient water storage volume in the tree pit will limit the retention capacity of short-term rainwater or irrigation water. Low density and insufficient water storage together lead to rapid loss of soil moisture. Seedlings such as Haloxylon ammodendron are difficult to establish stable roots due to water shortage in the initial stage of colonization. Loose soil is easily eroded by wind, exposing plant roots and further reducing the survival probability. Therefore, developing an automated tree planting device with soil covering function and the ability to construct a water storage structure has become a key technical requirement for improving the efficiency of desert edge-locking projects.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-15In order to solve the problem of missing tree pit structure caused by defects in the soil covering process in the prior art, the present invention realizes the soil covering function by setting a soil covering ring 9. The soil covering ring 9 is inserted into the soil, and the soil is moved by the soil expelling piece 901 to gather toward the seedling 10 to form a tree pit to ensure the realization of the water storage function. After the soil expelling piece 901 is opened, the soil covering ring 9 drives the soil expelling piece 901 to rotate to achieve soil compaction. The standardized soil covering ring 9 ensures that each tree pit has sufficient depth and size, and ensures that it has sufficient water storage capacity to avoid rapid loss of soil moisture, and ensure that seedlings such as Haloxylon ammodendron can establish root systems in the early stage of planting, thereby curbing land desertification. The present invention provides a technical solution: a fully automatic desert tree planting device, comprising a vehicle body 1, a seedling barrel 2, and seedlings 10. The vehicle body 1 adopts an existing vehicle that can travel in the desert. The vehicle body 1 is provided with a seedling barrel 2, and a plurality of seedlings 10 are placed in the seedling barrel 2. A drill rod 5 is also provided on one side of the vehicle body 1, and the drill rod 5 can move in horizontal and vertical directions. A seedling clamp 4 that can clamp the seedlings 10 and send them into the drill rod 5 is provided next to the seedling barrel 2, and a seedling pressing rod 8 that pushes the seedlings 10 is provided next to the drill rod 5. A covering ring 9 for filling soil for the seedlings is provided under the seedling pressing rod 8. In the present application, electrical components such as motor cylinder push rods all adopt existing models. After the tree is planted, the seedling 10 is put into the drilling rod 5 by the seedling clamp 4, and the drilling rod 5 is moved to the bottom of the drilling rod 5 by the transverse plate 7. The descending plate 6 is started, and the descending plate 6 drives the drilling rod 5 to drill a hole. When the required depth is reached, the drilling is stopped, and the seedling 10 is pushed out of the drilling rod 5 by the seedling pressing rod 8. The seedling pressing rod 8 is kept pressed down, and the drilling rod 5 is raised until the drilling rod 5 leaves the land but does not separate from the seedling 10, and the covering ring 9 is moved to be concentric with the seedling pressing rod 8, and then the covering ring 9 is pressed down to insert the covering ring 9 into the land, and then the covering ring 9 is started to realize the covering of the seedling 10 and the tree pit construction. After completion, the covering ring 9 is retracted, the drilling rod 5 and the seedling pressing rod 8 are reset, and the next tree planting is carried out by adjusting the seedling barrel 2 and the seedling emergence screw rod 3.

[0022] To achieve soil covering and compaction and construct a tree pit, one side of the soil covering ring 9 is provided with an opening, the width of the opening is greater than the diameter of the drill pipe 5, a convex platform is arranged inside the soil covering ring 9, one end of a number of soil scraping plates 901 is hinged on the convex platform, the outer side of the hinged end of the soil scraping plate 901 is arc-shaped, teeth are arranged on the arc and meshed with the arc-shaped teeth 902, the arc length of the arc-shaped teeth 902 is less than that of the soil covering ring 9, it is arranged between the soil scraping plate 901 and the soil covering ring 9, the arc-shaped teeth 902 make limited sliding in the soil covering ring 9, teeth are arranged on both sides of the arc-shaped teeth 902, the teeth on the other side are meshed with the rotating gear 903, the rotating gear 903 is rotatably connected to the lower frame 904 and driven by a motor, the soil covering ring 9 is slidably connected to one end of the lower frame 904. The lower frame 904 is fixedly connected to the lower end of the soil covering pressing screw rod 905, a soil covering guide rod 908 for preventing it from rotating is also arranged beside the soil covering pressing screw rod 905, the soil covering guide rod 908 is also fixedly connected to the lower frame 904, both the soil covering pressing screw rod 905 and the soil covering guide rod 908 are slidably connected to the soil covering transverse moving slider 909, the outer thread of the soil covering pressing screw rod 905 is connected to the soil covering ring tooth slider 906, the soil covering ring tooth slider 906 is meshed with the slider gear 907, the slider gear 907 is driven by a motor, both the soil covering ring tooth slider 906 and the slider gear 907 are rotatably connected to the soil covering transverse moving slider 909, the soil covering transverse moving slider 909 is threadedly connected to the soil covering transverse moving screw rod 910, the soil covering transverse moving screw rod 910 is rotatably connected to the vehicle body 1 and driven by a motor.During use, start the motor. The motor drives the soil covering transverse movement lead screw 910 to rotate. The soil covering transverse movement lead screw 910 drives the soil covering transverse movement slider 909 to move. The soil covering transverse movement slider 909 drives the soil covering downward pressure lead screw 905 to move. When the soil covering downward pressure lead screw 905 moves to be concentric with the seedling pressing rod 8, start the motor of the slider gear 907. The motor drives the slider gear 907 to rotate. The slider gear 907 drives the soil covering ring gear slider 906 to rotate. The rotation of the soil covering ring gear slider 906 causes the soil covering downward pressure lead screw 905 to descend. The soil covering downward pressure lead screw 905 drives the lower frame 904 to descend. The lower frame 904 drives the soil covering ring 9 to descend until the soil covering ring 9 is inserted into the soil to the specified depth. At this time, start the motor of the rotating gear 903. The motor drives the rotating gear 903 to rotate. The rotating gear 903 drives the arc tooth 902 to slide in the soil covering ring 9. The arc tooth 902 causes the soil pushing piece 901 to swing towards the center of the soil covering ring 9 with the hinge position as the axis through the meshing relationship. The soil pushing piece 901 pushes the soil in the soil covering ring 9 towards the central sapling 10, realizing soil covering for the sapling, and at the same time reducing the soil height in the soil covering ring 9 to form a depression and create a tree pit. Since the rotation angle of the arc tooth 902 is limited, the swing angle of the soil pushing piece 901 is limited. When the soil pushing piece 901 reaches the maximum swing angle, the arc tooth 902 cannot continue to slide in the soil covering ring 9. At this time, continue to start the rotating gear 903. The rotating gear 903 drives the arc tooth 902 to move. The arc tooth 902 will push the soil covering ring 9 to rotate, causing the soil covering ring 9 to rotate by an angle greater than its upper opening. The soil covering ring 9 drives the soil pushing piece 901 to rotate, thereby compacting and leveling the soil to ensure that the tree pit has sufficient water storage capacity. When the soil covering is completed, reverse the soil covering ring 9 to its original position to prepare for the next soil covering.

[0023] To enable the seedling clip 4 to hold the sapling 10, a seedling shaft 202 is provided at the center of the seedling barrel 2. A number of seedling tubes 201 are arranged outside the seedling shaft 202. The multiple seedling tubes 201 are fixedly connected to each other, and the seedling tubes 201 are fixedly connected to the seedling barrel 2 and the seedling shaft 202. The seedling shaft 202 is rotatably connected to the vehicle body 1 through a bracket. The seedling shaft 202 is fixedly connected to the output end of a motor, and the motor is fixed on the bracket. The motor drives the rotation of the seedling barrel 2, and the sapling 10 is inserted into the seedling tube 201. On the side of the seedling barrel 2 away from the seedling clip 4, a seedling ejection lead screw 3 is provided. The seedling ejection lead screw 3 is threadedly connected to a seedling ejection slider 301. A seedling ejection push rod 302 is fixedly connected to the seedling ejection slider 301. The output end of the seedling ejection push rod 302 can be inserted into the seedling tube 201 to push out the sapling 10. The seedling ejection lead screw 3 is driven by a motor and is rotatably connected to the vehicle body 1 through a bracket. The seedling ejection slider 301 is vertically slidably connected to this bracket. When it is necessary to push out the sapling 10, start the seedling ejection lead screw 3. The seedling ejection lead screw 3 drives the movement of the seedling ejection slider 301. The seedling ejection slider 301 drives the movement of the seedling ejection push rod 302, so that the seedling ejection push rod 302 aligns with a seedling tube 201. At this time, stop moving the seedling ejection slider 301, and then start the seedling ejection push rod 302 to push out the sapling in the seedling tube 201 for clamping. When all the saplings 10 in this column of seedling tubes 201 in the vertical direction are pushed out, start the motor of the seedling barrel 2. The motor drives the rotation of the seedling shaft 202. The seedling shaft 202 drives the rotation of the seedling tubes 201. The seedling tubes 201 drive the rotation of the seedling barrel 2. The several seedling tubes 201 in the seedling barrel 2 move, so that the next column of seedling tubes 201 distributed radially in the seedling barrel 2 rotates to the vertical position, so that the seedling ejection push rod 302 aligns with the next column of seedling tubes 201, and cooperates with the up and down movement of the seedling ejection push rod 302 to push out the new sapling 10.

[0024] To place the saplings into the drill pipe, the seedling clamp 4 is installed on the claw plate 404. The seedling clamp 4 uses an existing pneumatic gripper to hold the sapling 10. The claw plate 404 is rotatably connected to the vertical slider 401. The claw plate 404 is driven to rotate by a motor. The vertical slider 401 is slidably connected to the vertical slide rail 402. The vertical slide rail 402 is slidably connected to the horizontal slide rail 403. Both the vertical slide rail 402 and the horizontal slide rail 403 use existing electric control slide rails. The horizontal slide rail 403 is fixedly connected to the vehicle body 1 through a bracket. Start the vertical slide rail 402 and the horizontal slide rail 403 to adjust the position of the seedling clamp 4 so that the seedling clamp 4 moves to the position where the sapling 10 extends. Start the horizontal slide rail 403. The horizontal slide rail 403 drives the vertical slide rail 402 to move closer to the seedling bucket 2. At the same time, start the vertical slide rail 402. The vertical slide rail 402 drives the vertical slider 401 to adjust the height. The vertical slider 401 drives the claw plate 404 to move. During this process, start the motor of the claw plate 404. The motor drives the claw plate 404 to rotate to a horizontal state. The claw plate 404 drives the seedling clamp 4 to rotate so that the seedling clamp 4 is aligned with the sapling 10. Then start the seedling clamp 4 to hold the sapling 10. After clamping the sapling 10, first start the horizontal slide rail 403. The horizontal slide rail 403 drives the vertical slide rail 402 to move away from the seedling bucket 2, thereby driving the seedling clamp 4 to move horizontally to completely extract the sapling 10 from the seedling pipe 201. Subsequently, start the vertical slide rail 402. The vertical slide rail 402 drives the vertical slider 401 to move to adjust the height of the seedling clamp 4. After completing the height adjustment, start the motor. The motor drives the claw plate 404 to rotate 90° to make the claw plate 404 rotate to a vertical state. The claw plate 404 drives the seedling clamp 4 to rotate to erect the sapling. Then adjust the position of the sapling 10 through the vertical slide rail 402 and the horizontal slide rail 403 so that the sapling 10 is aligned with the drill pipe 5. Start the vertical slide rail 402 again to lower the seedling clamp 4. The seedling clamp 4 drives the sapling 10 to insert into the drill pipe 5. Finally, the seedling clamp 4 releases the sapling 10, and the sapling 10 falls into the drill pipe 5.

[0025] For the convenience of planting saplings, the drill rod 5 is hollowly arranged, and an opening through which the sapling 10 can extend is provided at its lower end. To prevent the sapling 10 from falling prematurely, a flap is hinged at the opening through a torsion spring. The upper end of the drill rod 5 is provided with a flared opening for conveniently receiving the sapling. The upper end of the drill rod 5 is fixedly connected to a drill rod pulley 501, and the drill rod pulley 501 is sleeved outside the drill rod 5. A transmission pulley 502 is arranged beside the drill rod pulley 501, and the two rotate synchronously through a belt. The transmission pulley 502 is fixedly connected to the output end of the motor. The drill rod 5 is rotatably connected to a drill rod platform 503, and the drill rod platform 503 is fixed on a descending plate 6. The motor is fixedly connected to the descending plate 6. The descending plate 6 is rotatably connected to a descending lead screw 601, and the descending lead screw 601 is driven by the motor. The descending lead screw 601 is threadedly connected to a descending slider 602, and the descending slider 602 is fixedly connected to a transverse movement plate 7. The transverse movement plate 7 is rotatably connected to a transverse movement gear 701, and the transverse movement gear 701 is driven by the motor. The transverse movement gear 701 meshes with a transverse movement rack 702, and the transverse movement rack 702 is fixedly connected to the vehicle body 1 through a bracket. The transverse movement plate 7 is slidably connected to the bracket. After receiving the sapling 10, start the motor of the transverse movement gear 701. The motor drives the transverse movement gear 701 to rotate. Since the transverse movement gear 701 meshes with the transverse movement rack 702, the transverse movement gear 701 drives the transverse movement plate 7 to move horizontally until it moves under the seedling pressing rod 8. At this time, start the motors of the descending lead screw 601 and the transmission pulley 502. The rotation of the descending lead screw 601 drives the descending plate 6 to descend, and the transmission pulley 502 drives the drill rod pulley 501 to rotate through the belt, so that the drill rod 5 rotates and descends to drill a hole.

[0026] To push out the sapling, the seedling pressing rod 8 is fixedly connected to the lower end of a seedling pressing lead screw 801. The seedling pressing lead screw 801 is threadedly connected to a seedling pressing platform 804, and the seedling pressing platform 804 is fixedly connected to a seedling pressing slide rail 803. A seedling pressing slide 802 is slidably connected to the seedling pressing slide rail 803, and the seedling pressing slide 802 is rotatably connected to the seedling pressing lead screw 801. The seedling pressing lead screw 801 is driven by the motor, and the motor is fixed on the seedling pressing slide 802. The seedling pressing slide rail 803 is fixedly connected to the vehicle body 1. After the drilling is completed, start the motor of the seedling pressing lead screw 801. The motor drives the seedling pressing lead screw 801 to rotate. Since the seedling pressing platform 804 is fixed, the seedling pressing lead screw 801 moves downward. The seedling pressing lead screw 801 drives the seedling pressing slide 802 and the motor thereon to move downward and at the same time drives the seedling pressing rod 8 to move downward. The seedling pressing rod 8 enters the drill rod 5 to push out the sapling 10, and the sapling 10 pushes open the flap under the drill rod 5 and inserts into the soil. Then raise the drill rod 5 to cover the soil and then raise the seedling pressing rod 8.
