Attached Figure Description

[0018] Figure 1 This is a schematic diagram of a transplanting device for forestry seedlings according to the present invention.

[0019] Figure 2 This is a front view of a transplanting device for forestry seedlings according to the present invention. Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0021] Please see Figures 1-2 A transplanting device for forestry seedlings includes a support plate 1, and casters 2 are provided around the bottom of the support plate 1 to facilitate the overall movement of the device.

[0022] A number of limiting screws 14 are rotatably provided on the support plate 1. The limiting screws 14 pass through the support plate 1 and are provided with buried screws 15 at their lower ends. When the limiting screws 14 are rotated, the buried screws 15 can be driven to descend and be fixed to the ground, so that the overall position of the device is stable and not easy to move.

[0023] The support plate 1 is provided with a support column 3. The bottom of the support column 3 is provided with a rotating shaft. The rotating shaft is rotatably engaged with the support plate 1, and the lower end face of the support column 3 abuts against the upper end face of the support plate 1 so that the support column 3 can rotate on the support plate 1.

[0024] The support column 3 is provided with several grooves 10 along the circumference, and the grooves 10 extend along the axial direction of the support column 3 to the upper end face of the support plate 1. A connecting block 9 is slidably provided in the groove 10. A limiting groove 13 extending along the axial direction is provided on the inner wall of the groove 10. Limiting blocks matching the limiting groove 13 are provided on both sides of the connecting block 9, which can make the connection between the connecting block 9 and the support column 3 tighter, improve the connection strength, and facilitate the support of seedlings.

[0025] The slide groove 10 is provided with a lifting screw 11 extending along the axial direction. The top of the lifting screw 11 is provided with a rotating wheel 12 to facilitate the rotation of the lifting screw 11. The lifting screw 11 is screwed to the connecting block 9 and passes through the connecting block 9 and is rotatably connected to the support plate 1. When the lifting screw 11 is rotated, the connecting block 9 can be driven to move up and down.

[0026] The connecting block 9 is equipped with a telescopic rod extending radially along the support column 3. The telescopic rod is a telescopic hollow cylindrical rod made of rolled metal strip. The telescopic end of the telescopic rod is equipped with a clamping mechanism for clamping the seedling. When the support column 1 rotates, the axial position of the clamping mechanism can be adjusted. When the lifting screw 11 is rotated, the axial position of the clamping mechanism can be adjusted. The radial position of the clamping structure can be adjusted through the telescopic rod, thereby facilitating the adjustment of the seedling position.

[0027] The clamping mechanism includes a back plate 4 connected to a telescopic rod. A fixed plate 6 is provided at one end of the back plate 4. A movable screw 8 is rotatably provided on the fixed plate 6. A clamping plate 5 is screwed onto the movable screw 8. The back plate 4 is provided with several connecting grooves 7. A number of sliders are provided at one end of the clamping plate 5 near the back plate 4. The sliders are slidably disposed in the connecting grooves 7, and the sliders are provided with locking blocks that cooperate with the locking grooves on the inner wall of the connecting grooves 7 to limit the sliding movement of the clamping plate 5 and the back plate 4. The end of the movable screw 8 protrudes from the clamping plate 5, and a rotating rod 16 is provided on the protruding part. The rotating rod 16 can be easily rotated by moving it. When the rotating rod 16 rotates, the clamping plate 5 moves towards the fixed plate 6, which can clamp the seedling. In order to avoid scratching the seedling, rubber pads can be provided on the two opposing surfaces of the back plate 4 and the clamping plate 5.

[0028] Working principle: First, place the seedling between the fixing plate 6 and the clamping plate 5, then rotate the moving screw 8 in the forward direction to bring the two closer together and clamp the seedling;

[0029] Next, the device is moved to the side of the tree pit by the universal wheel 2, and at the same time the limit screw 14 is rotated to make the buried screw 15 extend into the ground or contact the ground to stabilize the position of the device.

[0030] Then rotate the support column 3 so that the seedling to be placed faces the direction of the tree pit (circumferential position). According to the height of the backfill soil around the tree pit, adjust the height of the seedling by rotating the lifting screw 11 in the forward direction (axial position). Then extend the telescopic rod so that the clamping mechanism moves the seedling towards the tree pit (radial position). When it moves to the top of the tree pit, rotate the support column 3 and extend or retract the telescopic rod to fine-tune the position of the seedling so that it is directly above the center of the tree pit. Then slowly rotate the lifting screw 11 in the reverse direction to lower the connecting block 9 and thus lower the seedling. When the telescopic rod contacts the backfill soil around the tree pit, if the bottom of the seedling has not yet fallen to the bottom of the tree pit, rotate the moving screw 8 in the reverse direction to separate the fixing plate 6 from the clamping plate 5. By reducing the friction with the seedling, the seedling slowly falls until it falls to the bottom of the tree pit.

[0031] In this embodiment, four sliding grooves 10 are evenly arranged along the circumference of the supporting column 3, so that four seedlings can be clamped at the same time. In other embodiments of this utility model, more than four sliding grooves 10 can be set according to the specific working conditions, so as to achieve the purpose of transplanting more seedlings at one time.

[0032] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
