Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forestry machinery, and in particular to a planting device for transplanting Tilia tomentosa tissue culture seedlings. BACKGROUND

[0002] In the process of transplanting Tilia tomentosa tissue culture seedlings, the root system of the tissue culture seedlings has extremely high requirements for the timeliness of water supply after transplantation due to the domestication and cultivation characteristics - if water cannot be quickly supplemented after planting, the root system is prone to water loss and shrinkage, directly affecting the survival rate of transplantation. However, the current planting devices for Tilia tomentosa tissue culture seedlings generally have the problem of separation of planting and irrigation processes, which cannot meet the core needs.

[0003] Most of the existing devices only have a single planting function and can only complete the operation of planting Tilia tomentosa tissue culture seedlings into the soil, and subsequent irrigation needs to be performed manually: the operator needs to carry a water bucket, a watering can, or a mobile irrigation device after the planting operation is completed, and then water the seedlings along the planting row. This mode not only increases labor costs and labor intensity, but more importantly, there is a "irrigation lag" problem - during the interval from planting to manual watering, the root system of the seedling has been exposed to dry soil or air, which is prone to water stress; at the same time, manual irrigation cannot accurately control the amount of water supplied to each seedling, which is prone to the situation of insufficient water supply to some seedlings and excessive water supply to some seedlings, further affecting the consistency of seedling growth and the overall survival rate.

[0004] A few devices that attempt to integrate irrigation functions also do not achieve action linkage between planting and irrigation: the irrigation system needs to be controlled by an additional switch, or the irrigation is started uniformly after the planting operation is completed, which cannot achieve "synchronous irrigation after planting is completed"; and the irrigation structure and the planting structure of some devices are independent of each other, and the water supply parameters need to be adjusted separately, which is cumbersome to operate and prone to the problem of misalignment between the irrigation position and the planting position, and the core pain point of timely and accurate water supply after transplantation of Tilia tomentosa tissue culture seedlings has not been solved.

[0035] The device needs to be used in cooperation with a seedling supply assembly, which is installed on the top of the mobile vehicle 1 and functions to transport single purple linden seedlings into the two material frames 104 one by one to realize continuous planting. The specific operation process is as follows: first, water is injected into the inner cavity of the liquid storage barrel 403 through the water injection valve 404 to complete water supply storage, then the distance between the left and right material frames 104 is adjusted according to the preset planting distance of the purple linden seedlings (the distance needs to be adapted to the plant distance), during operation, the hand wheel 108 is rotated forward or reversely to drive the bidirectional screw 107 to rotate around its axis, thereby driving the two adjusting frames 102 to move closer to or away from each other along the length direction of the guide rod 101, synchronously driving the lifting frame 103, the material frame 104, the planting bucket 105 and the auxiliary components to move to realize distance adjustment. During the adjustment process, the lifting frame 103 drives the sliding shaft 309 to move (the sliding shaft 309 is in sliding cooperation with the sleeve shaft 308 and does not affect the position of the sleeve shaft 308), the adjusting frame 102 drives the sleeve 401 to move (the sleeve 401 is in sliding cooperation with the mounting plate 402 and does not affect the position of the liquid storage barrel 403), and the hose 405 can adaptively change the position of the water injection cylinder 201. After the adjustment is completed, the rotation of the hand wheel 108 is stopped.

[0036] Subsequently, the planting operation is carried out, the control mobile vehicle 1 moves along the preset planting row from front to back, and the seedling assembly delivers two purple linden seedlings into the two side material frames 104 respectively, and the purple linden seedlings naturally fall into the planting bucket 105. When the mobile vehicle 1 reaches the preset planting area, the driving motor 301 is started, the output shaft thereof rotates around the axis, the transmission disc set 302 is synchronously rotated, the transmission disc set 302 drives the transmission rod 303 and the adjusting screw 304 to move and synchronously rotate towards the direction close to the rocker 306, and then drives the rocker 306 to rotate forward around the rotating connection point, the rocker 306 drives the sleeve shaft 308 and the sliding shaft 309 to move downward through the sliding groove 307, the lifting frame 103 vertically slides along the adjusting frame 102, and synchronously drives the material frame 104, the planting bucket 105 and the water injection cylinder 201 to move downward. When the water injection cylinder 201 moves downward with the lifting frame 103, the piston rod 202 moves downward synchronously, and when the top end of the piston rod 202 contacts the top surface of the positioning block 204, the water injection cylinder 201 continues to move downward, the piston rod 202 is limited and stopped by the abutment of the positioning block 204, at this time, the compression spring 203 is compressed and deformed, the water injection cylinder 201 continuously moves downward to form negative pressure in the inner cavity thereof, and the clear water in the liquid storage barrel 403 is sucked into the inner cavity of the water injection cylinder 201 through the hose 405 (one-way valve conduction) to complete the irrigation water storage. In the process of moving the planting bucket 105 downward, the driving rod 505 and the pulley 507 slide downward along the wall surface of the L-shaped plate 501 synchronously, when the pulley 507 contacts the inner wall of the inclined rod 504, the pulley 507 applies an outward pushing force to the inclined rod 504, drives the inclined rod 504 to rotate outward around the rotating connection point of the vertical rod 503 and the inclined rod 504, and the torsional spring 508 is elastically deformed. After the pulley 507 slides downward beyond the inclined rod 504, the inclined rod 504 reversely rotates under the elastic reset action of the torsional spring 508, and re-abuts with the wall surface of the L-shaped plate 501. At this time, the planting bucket 105 is stuck into the soil through the bottom pointed cone structure, and the planting hole is excavated.

[0037] When the transmission disc group 302 completes 180-degree rotation, it continues to rotate in the original direction, and through the threaded cooperation of the transmission rod 303 and the adjusting screw rod 304, the rocker 306 is pulled to rotate to the rear side around the rotation connection point, the rocker 306 drives the sleeve shaft 308 and the sliding shaft 309 to move upward, the lifting frame 103 moves vertically upward along the adjusting frame 102, synchronously driving the material frame 104 and the planting bucket 105 to be lifted upward, when the planting bucket 105 moves upward, the toggle lever 505 and the pulley 507 move upward, when the pulley 507 contacts the outer wall surface of the inclined rod 504, it slides upward along the outer wall surface of the inclined rod 504, an outward force is applied to the toggle lever 505, forcing the toggle lever 505 to rotate outward around the rotation shaft 106 and the rotation connection point of the lifting frame 103, the return spring 506 is compressed and deformed, the toggle lever 505 drives the rotation shaft 106 and the planting bucket 105 to rotate outward synchronously, the planting bucket 105 opens, the Tilia tomentosa seedling in the planting bucket 105 falls into the soil planting hole, the planting bucket 105 continues to be lifted, the pulley 507 contacts the outer wall of the vertical rod 503, so that the planting bucket 105 remains in the open state to avoid the seedling body from being stuck, at the same time, the water injection cylinder 201 moves upward with the lifting frame 103, the compression spring 203 releases the elastic potential energy and rebounds to reset, the water injection cylinder 201 and the piston rod 202 approach each other to fold, the volume of the inner cavity decreases to press the clean water, under the non-return action of the check valve at the end of the hose 405, the clean water is injected into the material frame 104 through the water injection cylinder 201, then flows into the planting bucket 105 along the material frame 104, and finally irrigates the root of the Tilia tomentosa seedling in the soil, completing the first automatic irrigation after planting, when the pulley 507 and the vertical rod 503 are disengaged, the return spring 506 releases the elastic potential energy and rebounds to reset, driving the toggle lever 505 and the pulley 507 to rotate reversely around the rotation shaft 106, the pulley 507 recontacts the wall surface of the L-shaped plate 501, the toggle lever 505 synchronously drives the rotation shaft 106 and the planting bucket 105 to rotate reversely, so that the planting bucket 105 restores to the closed state, at this time the transmission disc group 302 completes a complete rotation, and then enters the next rotation cycle, the seedling supply assembly synchronously delivers the next Tilia tomentosa seedling into the material frame 104, and the moving vehicle 1 continuously moves at the set speed (the moving speed matches the rotation speed of the driving motor 301), ensuring that the moving vehicle 1 reaches the next preset row spacing position to automatically start the next planting operation.

[0038] During the use of the device, according to the preset planting depth of the purple acer seedlings, the planting bucket 105 lifting height can be adjusted, the specific operation is: rotate the adjusting screw 304 forward or reverse, make the adjusting screw 304 slide along the length direction of the inner cavity of the transmission rod 303, adjust the length of the adjusting screw 304 extending out of the inner cavity of the transmission rod 303, the change of the length of the adjusting screw 304 extending out will change the limit rotation angle of the rocker 306, and then change the maximum lifting height of the lifting frame 103, finally adjust the depth of the planting bucket 105 into the soil, the change of the depth will synchronously affect the maximum moving height of the water injection cylinder 201, and then change the water suction amount of the inner cavity of the water injection cylinder 201, realize the linkage and adaptation of irrigation water amount and planting depth, for seedlings, the planting depth is shallow, the water suction amount of the water injection cylinder 201 is small, and the corresponding irrigation water amount is small, for seedlings with large plant type, the planting depth is deep, the water suction amount of the water injection cylinder 201 is large, and the corresponding irrigation water amount is large.

[0039] As shown in Figure 6 , Figure 7 and Figure 11 , it also includes a fixing bolt 601, a long circular hole 602 is opened in the vertical direction on the mounting piece 502, a plurality of mounting holes 603 are opened in the vertical direction on the lower half of the L-shaped plate 501, the mounting hole 603 is matched with the fixing bolt 601, the spacing of each mounting hole 603 is set according to the planting depth adjustment requirement, each mounting piece 502 is equipped with a fixing bolt 601, the mounting piece 502 is screwed and connected with the mounting hole 603 of the L-shaped plate 501 at the corresponding height through the long circular hole 602 after the fixing bolt 601 passes through the long circular hole 602, and the detachable fixed installation is realized.

[0040] When the extending length of the adjusting screw 304 is changed by rotating the adjusting screw 304, and then the lifting height of the planting bucket 105 is adjusted, the height of the mounting piece 502 needs to be adjusted synchronously, so that the contact position of the pulley 507 on the poking rod 505 and the inclined rod 504 can realize accurate cooperation at the preset position, in the specific operation, the fixing bolt 601 is unscrewed and removed, the fixing constraint of the mounting piece 502 and the L-shaped plate 501 is released, according to the current planting depth requirement, the mounting piece 502 is moved along the vertical wall surface of the L-shaped plate 501, so that the contact position of the pulley 507 on the poking rod 505 and the inclined rod 504 can meet the time sequence requirement of the opening and closing action of the planting bucket 105, after the mounting piece 502 is moved to the target height, the fixing bolt 601 passes through the long circular hole 602 on the mounting piece 502 and is screwed and connected with the mounting hole 603 of the L-shaped plate 501 at the corresponding height, and the fixing bolt 601 is tightened to complete the positioning and fixing of the height of the mounting piece 502.
