Description

Technical Field

[0001] This invention relates to the technical field of tree planting devices, and more particularly to a large-scale rapid tree planting device and method for forest tree breeding. Background Technology

[0002] In forestry ecological construction, large-scale land greening, and artificial forest cultivation, the efficiency of tree breeding and planting is directly related to the speed of ecological restoration and the benefits of forestry production. With the development of modern agriculture and forestry mechanization, tree planting operations have gradually shifted from relying entirely on manual labor to mechanized operations.

[0003] Currently, semi-automated planting methods are commonly used in most forest areas and afforestation projects on barren hills. Specifically, this method typically relies on mechanical digging devices to excavate holes at designated planting points, followed by manual planting of saplings by operators. The soil is then covered and compacted manually or with auxiliary machinery to secure the saplings and ensure their initial growth. While this semi-automated model is more efficient than traditional manual planting, significant technical bottlenecks remain: First, the digging and planting processes are not effectively integrated, and the sapling planting process still heavily relies on manual labor, resulting in a fragmented and discontinuous workflow. Second, the depth, posture, and root spread of manually planted saplings are difficult to maintain consistently, affecting later survival rates and the uniformity of tree growth. More significantly, when facing large-scale, high-density tree breeding and afforestation tasks, the manual operation becomes the efficiency bottleneck of the entire planting process. It is not only time-consuming and labor-intensive but also limited by labor and working environment, making it difficult to achieve efficient, rapid, and standardized planting operations. Especially during the afforestation season, which is highly seasonal and has a short window of opportunity, low operational efficiency directly affects the overall afforestation progress and the effectiveness of ecological engineering projects. Summary of the Invention

[0004] In view of this, the present invention provides a large-scale rapid tree planting device and method for forest tree breeding, which can overcome the shortcomings of existing tree planting methods, such as the failure to effectively connect the pit digging and planting links, and the fact that the seedling implantation process still relies heavily on manpower, is time-consuming and labor-intensive, and has low planting efficiency.

[0005] The technical solution provided by this invention is as follows: A large-scale rapid tree planting device for forest tree breeding, comprising: a mobile vehicle body with symmetrically symmetrically opened first circular holes on the mobile vehicle body; a lead screw motor symmetrically mounted on the mobile vehicle body; a lifting plate slidably connected to the mobile vehicle body, and the lead screw of the lead screw motor is threadedly connected to the lifting plate; a rotating cylinder symmetrically rotatably connected to the lifting plate; a first helical blade connected to the outer wall of the rotating cylinder; a sliding cylinder slidably connected to the inside of the rotating cylinder; a conical plate circumferentially rotatably connected to the sliding cylinder; a second helical blade connected to the conical plate, and the second helical blade contacting and engaging with the first helical blade; a rotating assembly disposed on the lifting plate for driving the rotating cylinder to rotate; a limiting assembly disposed on the rotating cylinder for limiting the sliding cylinder and the conical plate; and an unfolding assembly disposed on the rotating cylinder for driving the conical plate to rotate and unfold.

[0006] Furthermore, the rotating assembly includes: a drive motor mounted on the bottom of the lifting plate; a drive gear connected to the output shaft of the drive motor; and a driven gear connected to the outer wall of the rotating cylinder, wherein the driven gear meshes with the drive gear.

[0007] Furthermore, the limiting component includes: a ball bearing, with grooves spaced circumferentially on both the inner wall of the rotating cylinder and the outer wall of the sliding cylinder, the ball bearing rolling within the grooves; and a limiting rod, symmetrically connected to the top of the conical plate, with limiting grooves spaced circumferentially on the bottom of the sliding cylinder, the limiting rod located within the limiting grooves.

[0008] Furthermore, the unfolding assembly includes: a fixed frame symmetrically connected to the top of the rotating cylinder; a first electric push rod installed inside the fixed frame; a first ring connected to the telescopic rod of the first electric push rod; a vertical rod circumferentially spaced and connected to the bottom of the first ring, and the vertical rod slides through the interior of the sliding cylinder, with its lower end contacting and engaging with a conical plate; a first connecting rod circumferentially spaced and connected to the top of the sliding cylinder, and the first connecting rod slidably connected to the first ring; and a limiting block connected to the top of the first connecting rod, with the bottom of the limiting block contacting the top of the first ring.

[0009] Furthermore, it also includes: a protective shell, connected to the top of the lifting plate, with symmetrical second circular holes on the protective shell, and the drive motor, drive gear and driven gear are all located inside the protective shell; and a vertical tube, symmetrically connected to the inside of the protective shell.

[0010] Furthermore, it also includes: a liquid storage tank connected to the mobile vehicle body; a liquid pump installed inside the liquid storage tank; and a diversion pipe connected to the inlet of the liquid pump and kept in communication, with the end of the diversion pipe away from the liquid pump connected to the protective shell and located at the second circular hole.

[0011] Furthermore, it also includes a soil covering assembly, which comprises: a second electric push rod symmetrically mounted on the mobile vehicle body; a third electric push rod mounted on the mobile vehicle body; a second ring connected to the telescopic rod of the second electric push rod; a second connecting rod connected between the two second rings; a third connecting rod connected to the telescopic rod of the third electric push rod; a third ring connected to both ends of the third connecting rod; a hinge rod rotatably connected between the second ring and the third ring; and a cloth bag connected between the second ring, the third ring, and the hinge rod.

[0012] Furthermore, it also includes: storage boxes, symmetrically connected to the mobile vehicle body.

[0013] Another technical solution of the present invention: a tree planting method for a large-scale rapid tree planting device for forest tree breeding, comprising the following steps: First, transport the device to a designated location, then connect the mobile vehicle to a tractor, and then move the mobile vehicle by the tractor. When the rotating cylinder is aligned with the position where the seedling needs to be transplanted, control the tractor and the mobile vehicle to stop moving. Then, control the drive motor to drive the active gear to rotate, the active gear drives the driven gear to rotate, the driven gear drives the rotating cylinder to rotate, and the rotating cylinder drives the first spiral blade, the sliding cylinder, the conical plate, and the second spiral blade to rotate. Then, control the screw motor to drive the lifting plate to move downwards, and the lifting plate drives the rotating cylinder, the first spiral blade, the conical plate, and the second spiral blade to move downwards. Under the action of the first and second spiral blades, a pit can be dug in the soil. During this pit digging process, the operator can put two seedlings into the two sliding cylinders respectively, so that the seedlings fall down to the inside of the conical plate. At this time, the conical plate is in a closed state, and the seedlings will not continue to fall down, which can temporarily fix the position of the seedlings. After the pit is dug, control the drive motor. The operation is stopped, causing the rotating cylinder, first helical blade, sliding cylinder, conical plate, and second helical blade to cease rotation. Then, the lead screw motor is controlled to drive the lifting plate upwards to reset. The lifting plate, in turn, moves the rotating cylinder, first helical blade, conical plate, and second helical blade upwards to reset, gradually moving the conical plate away from the pit. Simultaneously, the first electric push rod is controlled to drive the first ring and vertical rod downwards. Under gravity, the sliding cylinder moves downwards relative to the rotating cylinder, causing the conical plate, limiting rod, first connecting rod, and limiting block to move downwards relative to the rotating cylinder. This causes the limiting rod to disengage from the limiting groove. Through the limiting cooperation of the sliding groove and the ball, the downward distance of the sliding cylinder is limited. When the sliding cylinder, the conical plate, the limiting rod, the first connecting rod, and the limiting block stop moving downward, the first ring and the vertical rod will continue to move downward, causing the first ring to disengage from the limiting block. When the lower end of the vertical rod contacts the inner wall of the conical plate, the vertical rod will generate a downward pushing force on the conical plate. Combined with the gravity of the conical plate itself, it can cause the conical plate to rotate downward and open. At this time, the seedling located inside the conical plate will fall into the pit due to gravity.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention, through the coordinated operation of a rotating cylinder, a first spiral blade, a conical plate, and a second spiral blade, can automatically complete the seedling placement and soil covering process during the digging process. Specifically, the rotating component drives the rotating cylinder to rotate, and the unfolding component controls the opening and closing of the conical plate to achieve precise placement of seedlings into the pit. At the same time, the soil covering component automatically backfills the soil. This series of actions is seamlessly connected and has a high degree of continuity, which can improve the overall planting efficiency and is suitable for large-scale rapid tree planting operations.

[0016] 2. The limiting component of the present invention can ensure that the sliding cylinder and the conical plate remain stable during the movement, so that the seedling is planted at a consistent depth and with a consistent posture. After the conical plate is unfolded, it can temporarily limit the seedling to prevent it from tipping over. In conjunction with the soil covering action of the cloth bag, it can ensure the root system spread out and the soil covering is uniform. In addition, the liquid pump and the diversion pipe can accurately apply the rooting agent in the liquid tank to the roots of the seedling, further optimizing the growth conditions and improving the uniformity and survival rate of forest tree breeding.

[0017] 3. This invention adopts a modular structure, such as a combination of a liftable lifting plate and a rotating cylinder, to adapt to different soil types and terrain requirements. The soil covering component adjusts the shape of the cloth bag through the second and third electric push rods to achieve efficient soil backfilling. The protective shell and storage frame protect the transmission components and store seedlings respectively, enhancing the durability of the equipment and the continuity of operation. This design is particularly suitable for afforestation tasks with strong seasonality and short time windows, effectively overcoming the efficiency bottleneck of traditional semi-mechanized planting.

[0032] like Figure 3 and Figure 4 As shown, the limiting assembly includes a ball bearing 13 and a limiting rod 14. The inner wall of the rotating cylinder 4 and the outer wall of the sliding cylinder 6 are both circumferentially spaced with four sliding grooves 12. A ball bearing 13 is provided between the sliding grooves 12 on the rotating cylinder 4 and the sliding cylinder 6. The ball bearing 13 can roll in the sliding groove 12.

The top of the lifting plate 3 is connected to the protective shell 22, and the protective shell 22 has symmetrically opened second circular holes 2201. The second circular holes 2201 are located directly above the first circular hole 101. The drive motor 9, the driving gear 10 and the driven gear 11 are all located inside the protective shell 22. The vertical tube 23 is symmetrically connected to the inside of the protective shell 22, and the vertical tube 23 is vertically aligned with the second circular hole 2201.

[0035] like Figure 1 and Figure 7 As shown, it also includes a liquid storage tank 24, a liquid pump 25, and a diversion pipe 26. The liquid storage tank 24 is connected to the right side of the mobile vehicle body 1. The liquid pump 25 is installed on the right side of the bottom of the liquid storage tank 24. The liquid inlet of the liquid pump 25 is connected to the diversion pipe 26 and kept in communication. The diversion pipe 26 is a three-way pipe. The other two ends of the diversion pipe 26 are fixedly connected to the protective shell 22 and are located at the two second round holes 2201 respectively.

[0036] like Figures 8-10As shown, it also includes a soil covering assembly, which includes a second electric push rod 27, a third electric push rod 28, a second ring 29, a second connecting rod 30, a third connecting rod 31, a third ring 32, a hinge rod 33, and a cloth bag 34. The second electric push rods 27 are symmetrically installed on the left side of the mobile vehicle body 1, and the third electric push rod 28 is installed on the bottom left side of the mobile vehicle body 1. The telescopic rods of the two second electric push rods 27 are each connected to a second ring 29. The second ring 29 is vertically aligned with the first circular hole 101. The right sides of the two second rings 29 are connected to a second connecting rod 30, and the second connecting rod 30 is slidably connected to the mobile vehicle body 1. The telescopic rod of the third electric push rod 28 is connected to a third connecting rod 32. The rod 31 has a third ring 32 connected to both its front and rear ends. The third ring 32 corresponds one-to-one with the second ring 29, and the third ring 32 is located directly below the second ring 29. There are multiple sets of hinge rods 33 between the second ring 29 and the third ring 32. Each set of hinge rods 33 has three members, and the three hinge rods 33 in the same set are arranged vertically and connected end to end by hinge. The upper hinge rod 33 in each set of hinge rods 33 is hinged to the second ring 29, and the lower hinge rod 33 in each set of hinge rods 33 is hinged to the third ring 32. A cloth bag 34 is connected between the bottom of the second ring 29 and the top of the third ring 32. The outer side of the cloth bag 34 is connected to the inner side of the hinge rod 33.

[0037] like Figure 1 As shown, it also includes a storage box 35, which is symmetrically connected to the front and rear of the right side of the mobile vehicle body 1.

[0038] In the initial state, such as Figure 9As shown, the cloth bag 34 is cylindrical. When the device is needed, first transport the device to the designated location, then stack an appropriate amount of seedlings horizontally in the two storage boxes 35, then put an appropriate amount of rooting agent into the storage tank 24, then connect the mobile vehicle 1 to the tractor, then have an operator sit on the mobile vehicle 1, and then the tractor can drive the mobile vehicle 1 to move, so as to move the device.When the rotating cylinder 4 is aligned with the location where the sapling needs to be transplanted, the tractor and the moving vehicle 1 are stopped. Then, the second electric push rod 27 and the third electric push rod 28 are controlled to drive the second ring 29, the second connecting rod 30, the third connecting rod 31, the third ring 32, the hinge rod 33, and the cloth bag 34 downwards, so that the bottom of the third ring 32 contacts the soil. Then, the drive motor 9 is controlled to drive the drive gear 10 to rotate, the drive gear 10 drives the driven gear 11 to rotate, the driven gear 11 drives the rotating cylinder 4 to rotate, and the rotating cylinder 4 drives the first spiral blade 5, the sliding cylinder 6, the conical plate 7, and the second spiral blade 8 to rotate. Then, the screw motor 2 is controlled to drive the lifting plate 3 to move downwards, and the lifting plate 3 drives the rotating cylinder 4 and the first spiral blade 5 to move downwards. The conical plate 7 and the second helical blade 8 move downwards, allowing the rotating cylinder 4, the first helical blade 5, the conical plate 7, and the second helical blade 8 to pass through the first circular hole 101, the second circular ring 29, and the third circular ring 32. Subsequently, under the action of the first helical blade 5 and the second helical blade 8, a pit is dug in the soil. The first helical blade 5 and the second helical blade 8 then throw the soil from the pit upwards into the cloth bag 34. During this process, the operator can place two saplings from the storage frame 35 into the two second circular holes 2201. The saplings fall downwards through the vertical pipe 23 and the sliding cylinder 6 to the inside of the conical plate 7. At this time, the conical plate 7 is in a closed state, and the saplings will not continue to fall downwards, thus temporarily fixing the position of the saplings. The pit is dug... Afterwards, control the drive motor 9 to stop working, causing the rotating cylinder 4, the first helical blade 5, the sliding cylinder 6, the conical plate 7, and the second helical blade 8 to stop rotating. Then, control the lead screw motor 2 to drive the lifting plate 3 to move upwards to reset. The lifting plate 3 drives the rotating cylinder 4, the first helical blade 5, the conical plate 7, and the second helical blade 8 to move upwards to reset, causing the conical plate 7 to gradually move away from the pit. At the same time, control the first electric push rod 17 to drive the first ring 18 and the vertical rod 19 to move downwards. Under the action of gravity, the sliding cylinder 6 will move downwards relative to the rotating cylinder 4. The sliding cylinder 6 drives the conical plate 7, the limiting rod 14, the first connecting rod 20, and the limiting block 21 to move downwards relative to the rotating cylinder 4, causing the limiting rod 14 to disengage from the limiting groove 15 and pass through the sliding groove 1. The limiting cooperation between ball 2 and ball 13 limits the descent distance of the sliding cylinder 6. When the sliding cylinder 6, conical plate 7, limiting rod 14, first connecting rod 20 and limiting block 21 stop moving downward, the first ring 18 and vertical rod 19 will continue to move downward, causing the first ring 18 to disengage from the limiting block 21. When the lower end of the vertical rod 19 contacts the inner wall of the conical plate 7, the vertical rod 19 will generate a downward pushing force on the conical plate 7. Combined with the gravity of the conical plate 7 itself, the conical plate 7 can rotate downward and open. At this time, the seedling located inside the conical plate 7 will fall into the pit due to gravity. Then, the second electric push rod 27 is controlled to drive the second ring 29 and the second connecting rod 30 to move upward and reset, causing the hinge rod 33 to rotate and unfold. Figure 10As shown, at this time, the cloth bag 34 will be in a vertical elliptical shape, so that the soil inside the cloth bag 34 will fall down due to gravity, allowing the soil to automatically backfill into the pit. During the soil backfilling process, the upper part of the sapling is still located inside the conical plate 7. The conical plate 7 can limit the sapling to a certain extent and prevent the sapling from tipping over. Then, control the third electric push rod 28 to drive the third connecting rod 31 and the third ring 32 to move upward and reset, so that the cloth bag 34 can return to its original shape. Then control the liquid pump 25 to draw the rooting agent in the storage tank 24 and deliver the rooting agent to the second round hole 2201 through the diversion pipe 26. Subsequently, the rooting agent can be applied around the sapling through the vertical pipe 23, the sliding cylinder 6 and the conical plate 7 to promote the subsequent growth of the sapling. When the lifting plate 3 is completely reset, the first electric push rod 17 can be controlled to drive The first ring 18 and the vertical rod 19 move upwards to reset, causing the lower end of the vertical rod 19 to disengage from the inner wall of the conical plate 7. When the top of the first ring 18 re-contacts the bottom of the limiting block 21, the first ring 18 can drive the limiting block 21 and the first connecting rod 20 to move upwards to reset. The first connecting rod 20 drives the sliding cylinder 6 to move upwards relative to the rotating cylinder 4 to reset. The sliding cylinder 6 drives the conical plate 7 and the limiting rod 14 to move upwards relative to the rotating cylinder 4 to reset. When the conical plate 7 contacts the bottom of the rotating cylinder 4, the conical plate 7 will be pressed and reversed to close, so that the limiting rod 14 can be re-inserted into the limiting groove 15. In this way, a series of operations such as planting seedlings, adding rooting agents, and covering soil can be completed at the same time as digging the hole. The continuity is good and the work efficiency can be improved. By repeating the above operations, the seedlings can be automatically planted to the next designated position.

[0039] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.

9. A tree planting method for a large-scale rapid tree planting device for forest tree breeding according to claim 4, characterized in that, The process includes the following steps: First, the device is transported to the designated location. Then, the mobile vehicle (1) is connected to the tractor. The tractor then moves the mobile vehicle (1). When the rotating cylinder (4) is aligned with the location where the seedlings need to be transplanted, the tractor and the mobile vehicle (1) are stopped. Then, the drive motor (9) is controlled to drive the active gear (10) to rotate. The active gear (10) drives the driven gear (11) to rotate. The driven gear (11) drives the rotating cylinder (4) to rotate. The rotating cylinder (4) drives the first spiral blade (5), the sliding cylinder (6), the conical plate (7), and the second spiral blade (8) to rotate. Then, the screw motor (2) is controlled to drive the lifting plate (3) to move downwards. (3) Drive the rotating cylinder (4), the first spiral blade (5), the conical plate (7) and the second spiral blade (8) to move downwards. Under the action of the first spiral blade (5) and the second spiral blade (8), a pit can be dug in the soil. During the digging process, the operator can put two saplings into the two sliding cylinders (6) respectively, so that the saplings fall down to the inside of the conical plate (7). At this time, the conical plate (7) is in the closed state, and the saplings will not continue to fall down. The position of the saplings can be temporarily fixed. After the pit is dug, control the drive motor (9) to stop working, so that the rotating cylinder (4), the first spiral blade (5), the sliding cylinder (6), the conical plate (7) and the second spiral blade (8) stop rotating. Then, control the screw motor (2) to drive the lifting plate (3) to move upward and reset. The lifting plate (3) drives the rotating cylinder (4), the first spiral blade (5), the conical plate (7), and the second spiral blade (8) to move upward and reset, so that the conical plate (7) gradually moves away from the pit. At the same time, control the first electric push rod (17) to drive the first ring (18) and the vertical rod (19) to move downward. Under the action of gravity, the sliding cylinder (6) will move downward relative to the rotating cylinder (4). The sliding cylinder (6) drives the conical plate (7), the limiting rod (14), the first connecting rod (20), and the limiting block (21) to move downward relative to the rotating cylinder (4), so that the limiting rod (14) disengages from the limiting groove (15) and passes through the sliding groove. The limiting cooperation of (12) and ball (13) makes the descent distance of the sliding cylinder (6) limited. When the sliding cylinder (6), conical plate (7), limiting rod (14), first connecting rod (20) and limiting block (21) stop moving downward, the first ring (18) and vertical rod (19) will continue to move downward, causing the first ring (18) to separate from the limiting block (21). When the lower end of the vertical rod (19) contacts the inner wall of the conical plate (7), the vertical rod (19) will generate a downward pushing force on the conical plate (7). Combined with the gravity of the conical plate (7) itself, the conical plate (7) can rotate downward and open. At this time, the seedlings located inside the conical plate (7) will fall into the pit due to gravity.
