Description

Technical Field

[0001] The invention belongs to the technical field of forestry transplanting equipment, and in particular relates to a forestry planting seedling transplanting device. Background Art

[0002] Forestry planting and seedling cultivation is a complex process involving multiple technical and management measures. Forestry seedling cultivation first needs to select tree species that are suitable for the local environment and have strong disease resistance. Seed treatment includes water immersion, hotbeds, and drug germination. The germinated seeds form seedlings. The roots of the seedlings are wrapped with nutrient soil and transplanted under appropriate soil and environmental conditions. After subsequent multiple transplanting and cultivation, they can be sold and planted as mature seedlings.

[0003] When transplanting the germinated saplings into the land, it is necessary to dig transplanting pits of equal depth and spacing on the ground and then place the saplings. The existing Chinese invention patent with patent publication number CN118044449B discloses a forestry planting seedling transplanting device, which clamps the trunk of the saplings through a manipulator to prevent the saplings from falling over during planting. Although this equipment can be used to help the saplings grow into strong seedlings after raising them, for the first transplanting of saplings, the saplings that have just completed the germination do not have a hard trunk, and it is difficult to clamp and transplant them. In addition, it cannot automatically complete the actions of planting seedlings, digging pits, transplanting, backfilling, etc., and requires more manpower to assist. In view of this, a forestry planting seedling transplanting device is provided. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a forestry planting seedling transplanting device.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A forestry planting seedling transplanting device comprises a frame, and also comprises: a seedling loading device located on the upper part of the frame, the seedling loading device comprises a vertically arranged guide tube, a fixed plate is installed at the top opening position of the guide tube, a rotating plate is coaxially rotated above the fixed plate, a dividing turntable is installed at the axis position of the rotating plate, a temporary storage tube is installed through the edge of the rotating plate, and the lower openings of the temporary storage tubes except the temporary storage tube facing the guide tube are blocked by the fixed plate;

[0007] The planter is located at the lower part of the seedling raiser, and the planter includes a wheel frame with a horizontally arranged rotation axis, a bracket plate is fixedly installed at a circumferential position of the wheel frame, a soil-breaking mechanism is rotatably connected to the bracket plate, and a top block is provided on the side of the bracket plate facing the soil-breaking mechanism. When the soil-breaking mechanism contacts the top block, it deforms and digs up the ground below. When the soil-breaking mechanism digs up the soil, a feeding opening is formed for the seedlings to fall to the ground.

[0008] Among them, when transplanting saplings, it is necessary to manually put the saplings with their roots facing down into the temporary storage tube. The saplings rotate with the temporary storage tube, and the wheel frame of the planter drives the soil-breaking mechanism to rotate in the height direction. When the soil-breaking mechanism passes the highest point and rotates to just below the guide tube, the temporary storage tube also rotates to face the guide tube, and the saplings inside fall into the soil-breaking mechanism under the guidance of the guide tube. The rotational connection position between the soil-breaking mechanism and the bracket plate is above the center of gravity of the soil-breaking mechanism, so that the soil-breaking mechanism remains vertical until it is blocked by the top block and keeps in contact with the ground at a slightly inclined angle. When the wheel frame drives the lower end of the soil-breaking mechanism to insert into the soil, the soil-breaking mechanism will also sweep over the top block position and be squeezed to both sides by the top block to open. When opening, the soil will be pulled to both sides to form a pit. At the same time, the feeding opening formed after opening allows the saplings to fall directly into the pit to complete the planting.

[0009] Furthermore, a transmission member is fixedly installed in the middle of the frame, and the transmission member includes a driving wheel, and a wheel axle is installed at the axis of the driving wheel. The driving wheel drives the synchronous shaft one and the synchronous shaft two to rotate respectively through the middle shaft and the sprocket group, and a traction wheel is installed at the end of the wheel axle. The linear speed of the earth-breaking mechanism driven by the wheel frame to rotate is greater than the forward speed of the frame.

[0010] Through the above technical scheme, in order to improve the accuracy of transplanting, the synchronous shaft 1 will provide a rotational driving force for the indexing turntable, and the synchronous shaft 2 will drive the wheel frame to rotate. The process is connected in series through the sprocket group to ensure the synchronization of rotation, that is, when the soil-breaking mechanism rotates to just below the guide tube, the turntable is driven to rotate, so that the saplings can be accurately loaded onto the soil-breaking mechanism. At the same time, the linear speed of the soil-breaking mechanism is greater than the travel speed of the transplanting equipment, so that after the lower end of the soil-breaking mechanism is inserted into the ground, the soil-breaking mechanism swings around the lower end due to the difference in moving speed between the upper and lower parts. During the swinging process, it will sweep over the top block position to complete the opening. Because of this movement mode of first touching the bottom and then passively sweeping over the top block position, the saplings can fall after digging the pit, thereby ensuring the accuracy of transplanting.

[0011] Furthermore, the earth-breaking mechanism includes an adapter seat that passes through the top and the bottom, and the adapter seat is rotatably installed with the end of the bracket plate. The adapter seat is rotatably installed with a support ear close to the bracket plate, a contact rod is installed on the top of the support ear, and a swing plate is installed on the bottom of the support ear. When the contact rod contacts the top block, the two swing plates are driven away from each other. When the contact rod is separated from the top block, the two swing plates approach each other to block the lower end of the adapter seat.

[0012] Through the above technical scheme, a specific configuration of a soil-breaking mechanism is disclosed, the adapter is an annular structure with a vertical midline, and a horizontal axis is formed near the support plate for rotational connection, and the two swing plates are suspended under the adapter through the support ears. When the wheel frame rotates, the soil-breaking mechanism can remain vertical due to the lower center of gravity and the rotation installation, so that the sapling can be received when passing directly under the guide tube until the contact rod is blocked by the top block, and it is also close to the ground at this time, so the soil-breaking mechanism can be kept stationary at a slightly inclined angle until the swing plate contacts and inserts into the ground. At this time, the adapter continues to rotate with the wheel frame, so that the contact rod swings around the lower end of the swing plate with the support ear and passes through the top block position, and the contact rod is squeezed by the top block to make the swing plate rotate around the support ear, that is, the two swing plates move away from each other to form a feeding port. During the process, the soil here will be pulled to both sides of the travel direction until the contact rod passes the top block position, and the entire soil-breaking mechanism rotates upward with the wheel frame, and the two swing plates will be reset to complete the actions of receiving the sapling, breaking the soil and digging a hole, and putting the sapling into the hole.

[0013] Furthermore, a through bucket is installed at the opening position on the top of the adapter seat. The through bucket adopts a trumpet-shaped structure that is thick at the top and thin at the bottom. When the two swing plates are close to each other, a conical overall structure that is thick at the top and narrow at the bottom is formed. The swing plates have a vertical side wall on the side where they are close to each other, and a reset part is installed on the swing plate at the vertical side wall.

[0014] Through the above technical solution, in order to ensure the stability of sapling acceptance and transportation, a through bucket is installed on the upper part of the transfer seat, and the lower end of the guide tube is not in direct contact with the upper end of the transfer seat, but a gap is left to allow the transfer seat to rotate smoothly. Therefore, the sapling falling from the guide tube needs to fall freely into the transfer seat without guidance, and the through bucket can receive the sapling, thereby improving the success rate of sapling acceptance without changing the size of the transfer seat and preventing the sapling from falling out of the transfer seat. The setting of the reset piece can make the two swinging parts The boards are gathered together to prevent the saplings from falling directly out of the lower end of the adapter due to impact. In addition, in order to successfully dig the soil, the swing board needs to be designed with a pointed shape at the bottom. In order to ensure the smooth transplanting of the saplings, the saplings should be planted as deep as possible when the swing board is opened. The swing board is designed to be a hollow semi-conical shape, so that the saplings are as close to the bottom as possible before the swing board is opened. In this way, the saplings are already in the middle and lower part of the pit when the swing board is opened. The planting depth is more reasonable, which can avoid lodging and ensure the stability of the saplings after transplanting.

[0015] Furthermore, a corrugated end surface is designed on one side of the top block corresponding to the contact rod, and a backfiller is installed on the frame facing the planter. The backfiller has two rollers whose bottoms are inclined and close to each other.

[0016] The above technical scheme is used to achieve the verticality of the saplings after transplanting. When the soil-breaking structure inserts the saplings into the soil, the contact rod will drive the swing plate to fan through the corrugated end surface, so that the loose soil on both sides can be pushed between the swing plates in batches, and gathered from both sides to the roots of the saplings synchronously, so that part of the soil is first covered on the roots of the saplings to complete the pre-burying of the saplings, so as to avoid the saplings from tilting and falling before the swing plate leaves the ground and a large amount of soil falls back. Because the rotation speed of the soil-breaking mechanism is greater than the travel speed, the saplings will be driven to tilt at a small angle against the travel direction during the upward separation from the saplings. As the equipment moves forward, the roller-type backfiller will roll over both sides of the saplings, and while compacting the soil from back to front, the saplings will be passively squeezed forward. In this way, the original backward tilt of the saplings can compensate for the passive forward tilt of the saplings squeezed by the backfiller, so that the verticality can be guaranteed after the roots of the saplings are compacted.

[0017] Furthermore, when the two swing plates are close to each other, the contact rod as a whole extends obliquely toward the bracket plate, and a bearing is installed in the middle of the contact rod for rotation along the center line of the contact rod, and the installation position of the bearing corresponds to the position of the top block.

[0018] Through the above technical scheme, in order to ensure that the saplings can smoothly escape from the ground-breaking structure from the lower end, the inclined design of the contact rod forms a shorter power arm, and the protruding length of the top block does not need to be too long, so that the two swing plates can be opened at a larger angle when digging the soil, ensuring that the saplings can smoothly escape from the ground-breaking structure and fall. In addition, the installation of the bearing can reduce the sliding friction of direct contact and turn it into dynamic friction of rolling contact, which can ensure that the wear at the contact position is reduced and the expansion angle of the swing plate is consistent when used for a long time.

[0019] Furthermore, guide rail one and guide rail two are installed on the frame, a synchronous frame is slidably installed between guide rail one and guide rail two, the seedling loader, backfiller and planter are fixedly connected to each other through the main body of the synchronous frame, and the main body is horizontally driven along guide rail one through a linear module.

[0020] Through the above technical scheme, in order to control the transplanting gap, the seedling loader, backfiller and planter are grouped together, which are fixedly connected to each other through a synchronous frame, and can be uniformly adjusted by sliding to achieve the control of the spacing between seedlings during transplanting. In addition, the seedling loader, backfiller and planter are fixedly connected to effectively avoid mutual misalignment after adjustment, ensuring that the fallen seedlings can be smoothly received and the soil at the roots of the seedlings after being loaded can be smoothly compacted.

[0021] Furthermore, the indexing turntable has a horizontally through-going mounting hole, the synchronization shaft 1 is horizontally mounted in the mounting hole, the indexing turntable can slide horizontally along the synchronization shaft 1, and the synchronization shaft 1 provides a rotational driving force for the indexing turntable.

[0022] Through the above technical solution, in order to ensure the stability of transmission after lateral adjustment, because all the indexing turntables are driven by a synchronous shaft 1, the indexing turntable needs to slide on the outside of the synchronous shaft 1 and can be driven to rotate while sliding. Therefore, the mounting hole of the indexing turntable is designed to be a regular polygon, and the cross-section of the synchronous shaft 1 is also the same regular polygon, so that the sliding connection can be achieved while ensuring synchronous rotation.

[0023] Furthermore, a relay sleeve is installed at the axis position of the wheel frame, and the relay sleeve is arranged on the outside of the second synchronous shaft. The relay sleeve can slide along the axis of the second synchronous shaft, and the second synchronous shaft can drive the relay sleeve to rotate synchronously.

[0024] Through the above technical solution, in communication with the synchronous shaft one, in order to achieve the compatibility of sliding adjustment and rotation connection, the inner hole of the relay sleeve in the middle of the wheel frame is also a regular polygon, and the synchronous shaft two is designed into an adaptive shape to ensure that the synchronous rotation and horizontal sliding do not interfere with each other.

[0025] Furthermore, a material placing plate is installed on the top of the frame, a seat plate is installed at the same height as the material placing plate, an operating gap is left between the material placing plate and the seat plate, and the seedling loading device is located in the operating gap.

[0026] Through the above technical scheme, saplings can be placed on the loading plate, and multiple layers can be arranged up and down to make the best use of the space in the height direction, so as to place more saplings at one time and reduce the number of stops to replenish saplings. In addition, the seat plate is convenient for operators to sit down and perform long-term loading operations, and the operating gap can provide a larger hand operation space. Combined with the temporary storage tube being designed at a high position such as the seat plate, it is convenient for operators to place the saplings into the lower temporary storage tube without obstruction, thereby reducing the difficulty of operation.

[0027] The beneficial effects of the present invention are as follows:

[0028] (1) The present invention uses a synchronous transmission structure to coordinate the seedling loading device and the planting device through the arrangement of the seedling loading device, the planting device and the transmission member, and the indexing turntable and the wheel frame rotate at a constant speed, so that the seedlings are supplied to the soil breaking structure one by one, and the seedlings are automatically loaded separately, and the displacement of the soil breaking structure is driven by the wheel frame to complete automatic pit digging and seedling planting, thereby realizing automated seedling transplanting;

[0029] (2) The present invention improves the planter so that the converged swing plate can receive the falling saplings and insert into the soil while moving with the wheel frame. The top block is squeezed to push the soil away from each other, thus completing the action of digging a hole and releasing the saplings. The saplings can also be pre-buried into the desired inclined state through multiple movements and guidance before being separated from the saplings, and the vertical transplanting of the saplings can be achieved by pushing forward and rolling with the backfiller.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] like Figure 1 - Fig.11 As shown, this embodiment provides a forestry planting seedling transplanting device, including a frame 1, a traction seat at the front end of the frame 1, which can be used to connect with an agricultural machine so as to be towed forward. When performing automated transplanting of seedlings, it is necessary to complete the actions of automatically digging a hole, automatically placing the seedling in the hole, and vertically compacting the root of the seedling. In order to solve how to achieve a one-stop hollowing, tree placement and compacting action, a specific configuration is provided to solve the problem of efficient and high-quality seedling transplanting;

[0044] Regarding the seedling loading device 4, the seedling loading device 4 is located on the upper part of the frame 1, refer to Figure 1 and Figure 6 The seedling loading device 4 includes a vertically arranged guide tube 42 for conveying the seedlings downward. A fixed plate 41 is installed at the top opening of the guide tube 42. The fixed plate 41 serves as a mounting platform on which the guide tube 42 can be fixedly mounted. A turntable 44 is coaxially rotated above the fixed plate 41. A dividing turntable 43 is installed at the axis of the turntable 44. The dividing turntable 43 drives the turntable 44 to rotate intermittently, and the rotation angle is fixed. A temporary storage tube 45 is installed at the edge of the turntable 44. The temporary storage tubes 45 are uniformly spaced and can temporarily accommodate the seedlings. In addition, except for the temporary storage tube 45 facing the guide tube 42, the lower openings of other temporary storage tubes 45 are blocked by the fixed plate 41, so the seedlings can be manually placed in the blocked temporary storage tube 45, and the material can be automatically and controllably dropped into the guide tube 42 as it rotates.

[0045] Regarding the planter 5, the planter 5 is located at the lower part of the seedling device 4, Figure 5 and Figure 7The planter 5 includes a wheel frame 51 with a horizontally arranged rotation axis, a bracket plate 53 is fixedly installed at a circumferential position of the wheel frame 51, and a soil-breaking mechanism is rotatably connected to the bracket plate 53. When the soil-breaking mechanism passes the highest point and rotates to the bottom of the guide tube 42, the temporary storage tube 45 also rotates to face the guide tube 42, and the seedlings inside fall into the soil-breaking mechanism under the guidance of the guide tube 42, completing automatic feeding. A top block 59 is provided on the side of the bracket plate 53 facing the soil-breaking mechanism, and the rotation connection position of the soil-breaking mechanism and the bracket plate 53 is at the soil-breaking mechanism. The wheel frame 51 is above the center of gravity of the soil-breaking mechanism, so that the soil-breaking mechanism remains vertical until it is blocked by the top block 59, keeping a slightly inclined angle to contact the ground. When the wheel frame 51 drives the lower end of the soil-breaking mechanism to insert into the soil, the soil-breaking mechanism will also sweep over the position of the top block 59 and be squeezed to open to both sides by the top block 59. When opening, the soil will be pulled to both sides to form a soil pit. At the same time, the discharge port 562 formed after opening is for the sapling to fall directly into the soil pit. When the soil-breaking mechanism moves upward and leaves the ground, the soil falls back to cover the roots of the saplings, completing the planting.

[0046] In a further embodiment, to improve the accuracy of transplanting, refer to Figure 3 and Figure 4 A transmission member 2 is fixedly installed in the middle of the frame 1, wherein the transmission member 2 includes a driving wheel 21. The driving wheel 21 serves as an active wheel and can be directly connected to the power source of the agricultural machine. At the same time, a wheel axle 24 is installed at the axis of the driving wheel 21, and a traction wheel 3 can also be installed at the end of the wheel axle 24. The traction wheel 3 contacts the ground and realizes the passive rotation of the wheel axle 24 under the traction of the agricultural machine. The driving wheel 21 drives the synchronous shaft 1 22 and the synchronous shaft 2 23 to rotate respectively through the middle shaft 25 and the sprocket group 26. The synchronous shaft 1 22 will provide a rotational driving force for the indexing turntable 43, and the synchronous shaft 2 23 will drive the wheel frame 51 to rotate. The process is connected in series through the sprocket group 26 to ensure the synchronization of the rotation. That is, when the soil-breaking mechanism rotates to the bottom of the guide tube 42, the turntable 44 is driven to rotate, so that the precise feeding of the saplings to the soil-breaking mechanism can be realized. Fig.11 The linear speed of the rotation of the soil-breaking mechanism driven by the wheel frame 51 is greater than the linear speed of the rotation of the tire tread. At this time, the linear speed of the rotation of the soil-breaking mechanism is greater than the travel speed of the transplanting equipment, which can ensure that after the lower end of the soil-breaking mechanism is inserted into the ground, the soil-breaking mechanism swings around the lower end due to the difference in moving speed between the upper and lower parts. During the swinging process, it will sweep over the position of the top block 59 to complete the opening. Because of this movement mode of first touching the bottom and then passively sweeping over the position of the top block 59, the sapling can fall after digging the pit, thereby ensuring the accuracy of transplanting.

[0047] In a further embodiment, a specific configuration of a ground-breaking mechanism is disclosed, referring to Figure 7 and Figure 8The soil-breaking mechanism includes an adapter seat 54 that passes through from top to bottom. The adapter seat 54 is rotatably installed with the end of the bracket plate 53. The adapter seat 54 is an annular structure with a vertical midline, and a horizontal axis is formed near the bracket plate 53 for rotational connection, wherein the adapter seat 54 is rotatably installed with a support ear 57 near the bracket plate 53, and two swing plates 56 are suspended below the adapter seat 54 through the support ear 57. When the wheel frame 51 rotates, due to the low center of gravity and the rotational installation, the soil-breaking mechanism can remain vertical, so that the sapling can be received when passing directly below the guide tube 42. Among them, a contact rod 58 is installed on the top of the support ear 57. When the soil-breaking structure approaches the ground, the contact rod 58 is blocked by the top block 59. At this time, the soil-breaking mechanism can be kept stationary at a slightly inclined angle. A swing plate 56 is installed at the bottom of the support ear 57. Fig. 9 and Fig.11 The rotation of the wheel frame 51 drives the entire earth-breaking mechanism downward, which will make the swing plate 56 contact and insert into the ground. At this time, the adapter seat 54 continues to rotate with the wheel frame 51, so that the contact rod 58 swings around the lower end of the swing plate 56 with the support ear 57 and passes through the position of the top block 59. The contact rod 58 is squeezed by the top block 59 to make the swing plate 56 rotate around the support ear 57, that is, the two swing plates 56 move away from each other to form a feeding port 562. During the process, the soil here will be pulled apart to both sides of the traveling direction until the contact rod 58 passes through the position of the top block 59 and the entire earth-breaking mechanism rotates upward with the wheel frame 51. The two swing plates 56 will be reset to complete the actions of receiving the saplings, breaking the soil and digging the pit, and putting the saplings into the pit.

[0048] In a further embodiment, in order to ensure the stability of the sapling acceptance and transportation, refer to Figure 5 and Fig. 9 A through bucket 55 is installed at the top opening of the adapter 54. The through bucket 55 adopts a trumpet-shaped structure with a thick top and a thin bottom. The through bucket 55 is installed on the upper part of the adapter 54. The lower end of the guide tube 42 is not in direct contact with the upper end of the adapter 54, but a gap is left to allow the adapter 54 to rotate smoothly. Therefore, the sapling falling from the guide tube 42 needs to fall freely into the adapter 54 without guidance. The through bucket 55 can receive the sapling, which improves the success rate of sapling reception without changing the size of the adapter 54 and prevents the sapling from falling outside the adapter 54. Figure 8 and Fig. 9When the two swing plates 56 are close to each other, they form a conical overall structure that is thick at the top and narrow at the bottom. In order to successfully dig the soil, the swing plates 56 need to be designed to be pointed at the bottom. In order to ensure smooth transplanting of the saplings, the saplings can be planted as deep as possible when the swing plates 56 are opened. The swing plates 56 are designed to be hollow semi-conical, so that the saplings can be as close to the bottom as possible before the swing plates 56 are opened. In this way, when the swing plates 56 are opened, the saplings are already in the middle and lower part of the pit, and the planting depth is more reasonable, which avoids lodging and ensures the stability of the saplings after transplanting. At the same time, the swing plates 56 have vertical side walls on one side close to each other, and the swing plates 56 have vertical side walls on the other side. A reset member 561 is installed at the vertical side wall. The setting of the reset member 561 can gather the two swing plates 56 together to prevent the saplings from falling directly out of the lower end of the adapter 54 due to impact. In addition, if the swing plate 56 is made of steel, the reset member 561 can adopt a block-shaped permanent magnet to use magnetic force for gathering and resetting. At the same time, the reset member 561 can also adopt a spring, and the two ends of the spring are respectively fixed on the two swing plates 56, and the spring force is used for gathering and resetting. The reset member 561 can also be a multi-component mechanism. As long as it can realize the function of gathering and resetting the swing plate 56, it will not be repeated here.

[0049] In a further embodiment, in order to achieve the verticality of the saplings after transplanting, refer to Fig.10 A corrugated end surface 591 is designed on one side of the top block 59 corresponding to the contact rod 58. When the soil-breaking structure inserts the sapling into the soil, the contact rod 58 drives the swing plate 56 to swing through the corrugated end surface 591, so that the loose soil on both sides can be pushed to between the swing plates 56 in batches, and gathered to the roots of the saplings from both sides synchronously, so that part of the soil is first covered on the roots of the saplings to complete the pre-embedding of the saplings, and to prevent the saplings from tilting and falling before the swing plate 56 is separated from the ground and a large amount of soil falls back. Among them, because the saplings need to be compacted after pre-embedding, a backfiller 6 is installed on the frame 1 opposite to the planter 5. The backfiller 6 has two The rollers with their bottoms inclined and close to each other are used to compact the roots after pre-embedding. Because the roller-type backfiller 6 will roll over both sides of the sapling, and compact the soil from back to front, it will passively squeeze the sapling forward. This will cause the sapling to tilt forward and affect the survival rate. Therefore, the rotation speed of the soil-breaking mechanism is greater than the travel speed, and the sapling will be driven to tilt at a small angle away from the travel direction during the upward separation from the sapling. In this way, as the equipment moves forward, the sapling is first tilted backward for pre-embedding, and then reset forward when the backfiller 6 is pressed forward, so that the sapling can be kept vertical after the roots are compacted.

[0050] In a further embodiment, in order to ensure that the saplings can be smoothly removed from the soil breaking structure from the lower end, refer to Figure 8When the two swing plates 56 are close to each other, the contact rod 58 extends obliquely toward the bracket plate 53 as a whole. The inclined design of the contact rod 58 forms a shorter power arm. The protruding length of the top block 59 does not need to be too long, so that the two swing plates 56 can be opened at a larger angle when digging the soil, ensuring that the saplings can smoothly break away from the soil breaking structure and fall. At the same time, Fig. 9 A bearing is installed in the middle of the contact rod 58 for rotation along the center line of the contact rod 58. The installation position of the bearing corresponds to the position of the top block 59. The installation of the bearing can reduce the sliding friction of direct contact and turn it into dynamic friction of rolling contact, which can ensure that the wear of the contact position is reduced and the expansion angle of the swing plate 56 is consistent during long-term use.

[0051] In a further embodiment, in order to control the transplanting gap, refer to Figure 5 , a guide rail 11 and a guide rail 2 12 are installed on the frame 1, and a synchronous frame 8 is slidably installed between the guide rail 11 and the guide rail 2 12. The seedling loader 4, the backfiller 6 and the planter 5 are a group, and are fixedly connected to each other through the synchronous frame 8. They can be uniformly slid and adjusted to achieve the control of the spacing between seedlings during transplanting. Moreover, the seedling loader 4, the backfiller 6 and the planter 5 are fixedly connected to each other through the main body 81 of the synchronous frame 8, which can effectively avoid mutual misalignment after adjustment, ensure that the seedlings can be smoothly received when they fall, and the root soil of the seedlings after being loaded can be smoothly compacted. The main body 81 is driven horizontally along the guide rail 11 by the linear module 82. The linear module 82 can use a manual screw nut assembly to perform synchronous spacing adjustment. Of course, hydraulic telescopic rods can also be used between adjacent synchronous frames 8 to perform individual spacing adjustment of all synchronous frames 8. As long as the linear module 82 can adjust the spacing between the synchronous frames 8, the structure is not specifically limited and will not be repeated here.

[0052] In a further embodiment, in order to ensure the transmission stability after the lateral adjustment, since all the indexing turntables 43 are driven by a synchronous shaft 22, the indexing turntable 43 has a horizontal through mounting hole, and the synchronous shaft 22 is horizontally mounted in the mounting hole, so the indexing turntable 43 needs to slide on the outside of the synchronous shaft 22 and can be driven to rotate while sliding, so the mounting hole of the indexing turntable 43 is designed to be a regular polygon, and the cross section of the synchronous shaft 22 is also the same regular polygon, so that the sliding connection can be achieved while ensuring synchronous rotation;

[0053] Similarly, like the synchronous shaft 22, in order to achieve the compatibility of sliding adjustment and rotating connection, a relay sleeve 52 is installed at the axial position of the wheel frame 51. The relay sleeve 52 is arranged on the outside of the synchronous shaft 23. The inner hole of the relay sleeve 52 in the middle of the wheel frame 51 is also a regular polygon, and the synchronous shaft 23 is designed to be adapted. The relay sleeve 52 can slide along the axis of the synchronous shaft 23, and the synchronous shaft 23 can drive the relay sleeve 52 to rotate synchronously, thereby ensuring that the synchronous rotation and horizontal sliding do not interfere with each other.

[0054] In a further embodiment, referring to Figure 2 A loading plate 7 is installed on the top of the frame 1. The loading plate 7 is a flat plate with an upturned edge. The loading plate 7 can be used to place saplings, and multiple layers can be set up to make full use of the space in the height direction as much as possible, so as to place more saplings at one time and reduce the number of stops to replenish saplings. A seat plate is installed at a high position such as the loading plate 7. The seat plate is convenient for operators to sit down and perform long-term loading operations. Figure 1 An operating gap is left between the placing plate 7 and the seat plate, and the seedling loader 4 is located in the operating gap. The operating gap can provide a larger hand operating space. Combined with designing the temporary storage tube 45 at a high position such as the seat plate, it is convenient for operators to put the seedlings into the lower temporary storage tube 45 without obstruction, thereby reducing the difficulty of operation.

[0055] The working principle of this embodiment is as follows:

[0056] When transplanting saplings, the frame 1 is pulled by the agricultural machine and moves in a straight line in the field. The worker manually puts the saplings with their roots facing downward into the temporary storage tube 45 of the seedling loading device 4 on the frame 1. The temporary storage tube 45 rotates intermittently under the drive of the indexing turntable 43, and the wheel frame 51 of the planting device 5 rotates under the seedling loading device 4, driving the soil breaking mechanism to move up and down while moving forward and backward;

[0057] When the soil-breaking mechanism passes the highest point and rotates to the bottom of the guide tube 42, the indexing turntable 43 drives the temporary storage tube 45 containing the saplings to rotate at a certain angle to face the guide tube 42. The saplings inside fall into the soil-breaking mechanism with the opening facing upward under the guidance of the guide tube 42. The saplings are supported by the two closed swing plates 56 of the soil-breaking mechanism and move downward together with the soil-breaking mechanism. The soil-breaking mechanism moves downward in a vertical state until the contact rod 58 is blocked by the top block 59. Then, the soil-breaking mechanism moves downward with the lower part slightly tilted backward until it touches the ground.

[0058] The wheel frame 51 rotates to drive the swing plate 56 downward and insert it into the soil. Because the moving linear speed of the soil-breaking mechanism is greater than the forward speed of the agricultural machine, the soil-breaking mechanism will swing around the lower end of the swing plate 56 driven by the wheel frame 51. During the process, the contact rod 58 sweeps over the position of the top block 59, and the swing plate 56 is squeezed by the top block 59 to swing open to both sides perpendicular to the forward direction. When the swing plate 56 is opened, the soil is propped up to form a soil pit, and the sapling enters the soil pit from the discharge port 562 between the two swing plates 56.

[0059] The corrugated end surface 591 of the top block 59 causes the two swing plates 56 to swing back and forth. Before the swing plates 56 leave the ground, the fallen soil is gathered to the roots of the saplings in multiple times to pre-bury the saplings. When the soil-breaking mechanism separates from the saplings, the soil-breaking mechanism will drive the saplings to a state of slightly tilting backwards, and then the backfiller 6 will roll over both sides of the saplings from back to front, pushing the saplings to passively swing forward slightly, compensating for the angle at which the soil-breaking mechanism previously tilted the saplings backwards, ensuring that the soil at the roots of the saplings is compacted and in a vertical state.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
