Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tree planting devices, and in particular to a large-scale rapid tree planting device for forest tree breeding and a tree planting method. BACKGROUND

[0002] In the fields of forestry ecological construction, large-scale land greening, and artificial forest cultivation, forest tree breeding and planting efficiency directly affect the speed of ecological restoration and the production benefit of forestry. With the development of modern agriculture and forestry mechanization, tree planting operations have gradually shifted from complete reliance on manpower to mechanized auxiliary operations.

[0003] Currently, in most forest areas and barren mountain afforestation projects, semi-automatic tree planting methods are commonly used. Specifically, this method usually relies on mechanical hole digging devices to complete hole digging at predetermined planting points, and then a manual operator manually plants the seedlings one by one into the holes, and then covers and compacts the soil by hand or with the help of auxiliary machinery to ensure the fixation and initial growth of the seedlings. Although this semi-automatic mode has improved efficiency compared to traditional manual tree planting, it still has significant technical bottlenecks. First, the digging and planting stages do not effectively connect, and the seedling planting process still relies heavily on manpower, resulting in a fragmented overall operation process with poor continuity. Second, the depth, posture, and root stretch of manually planted seedlings are difficult to maintain consistent, affecting the survival rate and uniformity of tree growth. More importantly, when faced with large-scale, high-density forest tree breeding and afforestation tasks, the manual operation stage becomes the efficiency bottleneck of the entire planting process, not only consuming time and effort, but also being limited by labor and working environment, making it difficult to achieve efficient, rapid, and standardized tree planting operations. Especially in the afforestation season with strong seasonality and short time window, the low efficiency of operation directly affects the overall afforestation progress and the implementation effect of ecological engineering.

[0037] As shown in the initial state, Figure 1 It also includes a storage frame 35, which is symmetrically connected to the right part of the moving vehicle body 1.

[0038] In the initial state, as shown in the initial state, Figure 9As shown, the cloth bag 34 is cylindrical; when the device needs to be used, first transport the device to the designated location, then put the appropriate amount of seedlings into the two storage frames 35 respectively, and then put the appropriate amount of rooting agent into the storage tank 24, then connect the mobile vehicle body 1 with the towing vehicle, and then let an operator sit on the mobile vehicle body 1, and then the mobile vehicle body 1 can be moved by the towing vehicle to drive the device to move.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 vertically oval-shaped, so that the soil inside the cloth bag 34 will fall downward due to gravity, so that the soil can be automatically backfilled into the hole. During the soil backfilling process, the upper half of the sapling is still located inside the conical plate 7, and the conical plate 7 can limit the sapling to a certain extent to prevent the sapling from falling over. Then, the third electric push rod 28 is controlled to drive the third connecting rod 31 and the third circular ring 32 to move upward and reset, so that the cloth bag 34 returns to its original state. The liquid pump 25 is controlled to extract the rooting agent in the liquid storage tank 24, and the rooting agent is delivered to the second circular hole 2201 through the shunt 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 is controlled to drive the first circular ring 18 and the vertical rod 19 to move upward and reset, so that the lower end of the vertical rod 19 is separated from the inner wall of the conical plate 7. When the top of the first circular ring 18 recontacts the bottom of the limiting block 21, the first circular ring 18 can drive the limiting block 21 and the first connecting rod 20 to move upward and reset. The first connecting rod 20 drives the sliding cylinder 6 to move upward and reset relative to the rotating cylinder 4. The sliding cylinder 6 drives the conical plate 7 and the limiting rod 14 to move upward and reset relative to the rotating cylinder 4. When the conical plate 7 contacts the bottom of the rotating cylinder 4, the conical plate 7 will be reversely folded under pressure, so that the limiting rod 14 reinserts into the limiting slot 15. Thus, a series of operations such as planting saplings, adding rooting agents and covering soil can be completed while digging holes, which has good continuity and can improve work efficiency. By repeating the above operation, the sapling can be automatically planted in the next designated position.

[0039] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.

6. The planting method of a large-scale rapid tree planting device for forest tree breeding according to claim 1, 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) 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 this digging process, the operator puts 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, which can temporarily fix the position of the saplings. 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. The control screw motor (2) drives 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, the first electric push rod (17) needs to be controlled 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 ( 12) The limiting cooperation of the ball (13) and the sliding cylinder (6) limits the downward distance of the sliding cylinder (6). When the sliding cylinder (6), the conical plate (7), the limiting rod (14), the first connecting rod (20) and the limiting block (21) stop moving downward, the first ring (18) and the 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.
