Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forestry seedling planting equipment, in particular to an adjustable forestry tree seedling transplanting machine. BACKGROUND

[0002] It is a very common phenomenon in forestry tree planting that seedlings are transplanted according to production needs. When trees grow to a certain extent, they need to be transferred to a site with a larger spacing or a buyer's site. The process of tree transplanting is divided into two forms. One is to manually excavate the periphery of the roots of trees or seedlings until the entire root periphery of the trees or seedlings is cleaned to make the seedling roots lift off the ground, and then the trees or seedlings are transported to a vehicle for transfer. The advantage of this method is that personnel can determine the excavation range according to the root growth of the trees, without damaging the plant roots. The disadvantage is that manual excavation is inefficient and not suitable for large-scale transplanting operations. The other is to use a transplanting mechanical device to excavate the roots of trees or seedlings and integrally transport them to the target location. The disadvantage of this method is that the current transplanting equipment has a fixed excavation range. One tree or seedling can only use a corresponding size of transplanting machine, or different sizes of transplanting equipment need to be replaced according to the tree age. Since the size of the excavated transplanting machine is fixed and cannot be adjusted, it is easy to cause damage to the roots of the seedlings. For the case of many tree species and different tree diameters, the operation needs to be constantly replaced, increasing the transplanting cost.

[0003] Chinese patent document CN204259544U discloses a tree transplanting vehicle excavation system. An arc-shaped spade plate is arranged on a closable annular support. The roots of the seedlings are separated from the soil by moving the spade plate downward along the guide rail and closing it. This structure is the common structure of the current seedling transplanting machine. The position relationship of the guide rail determines the size of the excavated range, and it cannot be adjusted, so it can only be used for operation on seedlings with a specific root size. SUMMARY

[0004] The technical problem to be solved by the present application is to provide an adjustable forestry tree seedling transplanting machine that matches the size of the excavated roots with the root range of the tree species.

[0028] like Figures 1-6 As shown, an adjustable forestry seedling transplanter includes a connecting seat 4. The bottom of the connecting seat 4 is provided with two hinged semi-circular bases 5. The semi-circular bases 5 can be controlled to close into a ring shape. The semi-circular bases 5 are used to contact and support the ground. Each semi-circular base 5 is provided with a support seat 6. The support seat 6 is provided with a connecting frame 7 that slides linearly along the axis of the closed ring of the semi-circular base 5. The end of the connecting frame 7 is provided with a sliding arc rail 8. The lower end of the sliding arc rail 8 is provided with an arc-shaped shovel plate 9. The arc-shaped shovel plate 9 can slide along the sliding arc rail 8 in an arc. When the arc-shaped shovel plates 9 on the two semi-circular bases 5 are at the bottom limit position, they can be closed.

[0029] The openable semi-circular base 5 provides a supporting foundation for the sliding arc rail 8 and the arc-shaped shovel 9. When the arc-shaped shovel 9 digs into the soil, the reaction force of the soil on the arc-shaped shovel 9 is transmitted through the support seat 6 to the ring formed by the semi-circular base 5, and then to the connecting seat 4. Fixing the connecting seat 4 securely ensures that the arc-shaped shovel 9 can be smoothly driven into the soil. The closure at the extreme position achieves the separation of the seedling roots from the soil. In addition, by sliding the connecting frame 7 to the support seat 6, the position of the arc-shaped shovel 9 can be adjusted according to the different diameters of the seedlings, thereby avoiding the strong roots of large-diameter seedlings being cut off. At the same time, by lifting the entire device upward, the arc-shaped shovel 9 catches the roots and soil and separates the roots of the unclosed part of the arc-shaped shovel 9 from the soil, thus achieving the separation of the seedling from the soil.

[0030] The connecting seat 4 and the slide 3 are slidably connected. The connecting seat 4 can slide up and down on the slide 3 under control. The slide 3 is rotatably connected to the mobile carrier 1 and is driven from horizontal to vertical by the tilting cylinder 2.

[0031] like Figure 1 As shown, by sliding the connecting seat 4 up and down, the sapling and roots held by the arc-shaped shovel plate 9 can be moved out of the tree pit or placed into the newly dug tree pit. By extending and retracting the rotating cylinder 2, the entire device can be switched between horizontal and vertical states to facilitate digging and moving operations. The connecting seat 4 and the sliding seat 3 are connected by a cylinder to make the connecting seat 4 slide up and down.

[0032] The connecting frame 7 is equipped with a rotary motor 12, which can drive the combination of the sliding arc rail 8 and the arc-shaped shovel plate 9 at the end of the connecting frame 7 to rotate around the axis of the annular ring when the semi-circular base 5 is closed.

[0033] By driving the sliding arc track 8 and the arc spade 9 combination to rotate along the axis of the closed semi-circular base 5, when the tree diameter is large and the root range is large, the connecting frame 7 is opened away from the axis to avoid breaking the thick roots. When the arc spade 9 on the two circles reaches the limit position, it is no longer closed, as shown in Figure 5 , by reciprocating rotation, the sharp corners of the arc spade 9 can cut the uncut soil to completely separate the tree roots from the soil.

[0034] The support seat 6 described above is in the shape of an inverted "L", and the horizontal surface of the inverted "L" is provided with a linear slide rail set 16. The sliding part of the linear slide rail set 16 is fixedly connected with the connecting frame 7, and the connecting frame 7 is driven by the telescopic drive 17 to make telescopic movement along the axis.

[0035] As shown in Figure 6 , the linear slide rail set 16 allows the connecting frame 7 to telescope along the axis, thereby expanding or reducing the excavation range of the arc spade 9. Preferably, the linear slide rail set 16 is arranged on the horizontal lower surface of the inverted "L", so that when the arc spade 9 excavates the soil downward, the reaction force of the soil acts upward on the slider of the linear slide rail set 16, thereby being transmitted to the support seat 6 and then to the semi-circular base and the connecting seat 4 through the slide rail. The linear slide rail set 16 bears a compressive force rather than a tensile force, which conforms to the load characteristics of the linear slide rail set 16. The telescopic drive 17 can be an oil cylinder or a lead screw drive.

[0036] In a preferred embodiment, the connecting frame 7 described above includes an arc-shaped frame body 71, which is concentric with the semi-circular base 5. An arc-shaped gear ring 72 is arranged inside the frame body 71 to slide relative to the frame body 71. The two ends of the arc-shaped gear ring 72 protrude out of the frame body 71 and are fixedly connected with the sliding arc track 8. The arc-shaped gear ring 72 is driven to slide inside the frame body 71 by the rotary motor 12.

[0037] As shown in Figures 2-7 , the two ends of the arc-shaped gear ring 72 are fixedly connected with the sliding arc track 8, and the rotary motor 12 drives the gear ring to rotate, thereby driving the arc-shaped gear ring 72 to rotate along the center. Rollers can be arranged between the inner surface of the frame body 71 and the outer surface of the arc-shaped gear ring 72. In this case, due to the limitation of the length of the two ends of the arc-shaped gear ring 72 protruding out, the sliding arc track 8 will interfere with the frame body 71, and the rotation angle of the sliding arc track 8 and the arc spade 9 is relatively limited, which limits the telescopic distance of the connecting frame 7. A limiting block 73 is further arranged inside the frame body 71 to position the arc-shaped gear ring 72. In Figure 7 , the telescopic drive 17 is an oil cylinder.

[0038] In the preferred scheme, the connecting frame 7 comprises an arc-shaped frame body 71, which is concentric with the semi-circular ring base 5, and an arc-shaped gear ring 72, which is arranged in the frame body 71 and slides relative to the frame body 71. The rear part of the frame body 71 is provided with an opening, and the rear end of the arc-shaped gear ring 72 extends out of the opening of the frame body 71 and forms a connecting block 74. The arc-shaped ends of the connecting block 74 are fixedly connected with the sliding arc rail 8, and the arc-shaped gear ring 72 is driven by the rotary motor 12 to slide in the frame body 71.

[0039] As shown in Figure 8 and 9 , since the arc-shaped ends of the connecting block 74 are fixedly connected with the sliding arc rail 8, and the sliding arc rail 8 is located behind the frame body 71, the interference between the sliding arc rail 8 and the frame body 71 when the arc-shaped ends of the arc-shaped gear ring 72 are connected with the sliding arc rail 8 can be avoided, so that a larger rotation angle can be obtained. Figure 8 In Figure 7 , the telescopic drive 17 is a lead screw.

[0040] The middle part of the frame body 71 is provided with a clamping arm 13, which is directed to the center of the circle. The end of the clamping arm 13 is provided with two intersecting clamping plates 14, which are used to abut against the trunk of the sapling.

[0041] As shown in Figures 4-6 , according to the category of tree species, the length of the clamping arm 13 is set to a specific length, so that when the clamping plates 14 contact the trunk of the sapling, the position of the arc-shaped spade plate 9 is just in the area without thick and strong root parts.

[0042] The intersection angle of the two intersecting clamping plates 14 is ninety degrees.

[0043] The length of the clamping arm 13 is adjustable.

[0044] By setting the length of the clamping arm 13 to be adjustable, the clamping plates 14 can be adjusted according to different categories of tree species, so that when the clamping plates 14 contact the trunk, the arc-shaped spade plate 9 is just located at the edge of the root part, without causing damage to the root part.

[0045] The two semi-circular ring bases 5 are hinged with the connecting seat 4 through the opening and closing hinge 10. The two ends of the two semi-circular ring bases 5 are provided with connecting ears, which are rotatably connected with the opening and closing oil cylinder 11. The other end of the opening and closing oil cylinder 11 is rotatably connected with the connecting seat 4. The closed end of the two semi-circular ring bases 5 is provided with a pin hole for the insertion of the pin 15.

[0046] As shown in Figure 2As shown in the middle, connecting ears are arranged on both sides of the two semicircular ring bases 5, the connecting ears are rotationally connected with the opening and closing oil cylinder 11, the other end of the opening and closing oil cylinder 11 is rotationally connected with the connecting seat 4, the opening and closing of the two semicircular ring bases 5 can be controlled by the opening and closing oil cylinder 11, so that the saplings enter the device or move out of the device, and the force during digging can be transmitted to the connecting seat 4 through the three-point support of the opening and closing oil cylinder 11 and the opening and closing hinge 10, and the end of the two semicircular ring bases 5 is closed by the pin column 15 to lock the spindle.

[0047] The plurality of support seats 6 arranged in the combination of the sliding arc rail 8 and the arc-shaped spade plate 9 can improve the rigidity of the overall structure.
