Description

Technical Field

[0001] This invention relates to the field of planting technology, and in particular to a hole-digging device, a planting machine, and a planting method. Background Technology

[0002] Existing tree planting machines are mainly used in non-desert environments. They mainly include a hole-digging device and a seedling-dispensing device. The hole-digging device is used to dig planting holes, and after the planting holes are dug, the seedling-dispensing device puts the seedlings or seeds into the planting holes.

[0003] The following problems exist in using existing tree planting machines in desert environments: After the digging device has dug the planting hole, the planting hole may be submerged or covered due to slippage, movement of the mobile bearing chassis in the tree planting machine, or sand movement. This further causes the seedling delivery device to be unable to align with the planting hole, making it impossible to put the seedling or seed into the planting hole, ultimately resulting in low planting efficiency. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a hole-digging device, a planting machine, and a planting method to solve the problems of existing tree planting machines where the hole-digging operation and the seedling planting operation are separated, and in desert environments, after the hole-digging device has dug the planting hole, the planting hole is easily flooded or covered, and the seedling delivery device cannot be aligned with the planting hole, resulting in low planting efficiency.

[0068] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0069] Definition: such as Figure 1 As shown, the mounting box is facing upwards, and the drill bit is facing downwards.

[0070] Example 1

[0071] One embodiment of the present invention provides a hole-digging device Z1, such as... Figure 1 As shown, it includes a drive mechanism 100, a drilling mechanism 200, and an opening and closing control mechanism 300; the drive mechanism 100 is used to control the rotation and lifting of the drilling mechanism 200; the drilling mechanism 200 includes a drill bit 210 with a hollow cavity, one end of the drill bit 210 is open, and the other end is an opening and closing end, and the opening and closing control mechanism 300 is used to control the opening and closing of the opening and closing end.

[0072] The hole-digging device of this embodiment includes a drill bit with a hollow cavity and an opening and closing end. Therefore, when the hole-digging device of the present invention is used for planting trees, after the planting hole is dug, the opening and closing end is opened during the lifting of the drill bit to form an opening. At this time, the seedling located in the hollow cavity is left in the planting hole through the opening, thereby completing the planting.

[0073] Compared with existing tree planting robots that separate the digging and seedling placement operations, the digging device in this embodiment can immediately perform the seedling or seed placement operation after the planting hole is dug. This effectively avoids the problem that the seedling placement mechanism cannot accurately align with the planting hole due to slippage of the moving support chassis or sand movement after the planting hole is dug in the desert environment, thus significantly improving planting efficiency.

[0074] In some specific embodiments of the present invention, the drive mechanism 100 has a motor. Using a single motor, the drilling mechanism 200 can be driven simultaneously for both rotational and lifting movements. This not only offers advantages such as high synchronization, high stability, and simple control, but also reduces the overall weight of the drilling device Z1. For example... Figure 2 As shown, the drive mechanism 100 includes a drive motor 110 and a gear set 120. The gear set 120 includes a first gear 121 and a second gear 122. The first gear 121 is connected to the drilling mechanism 200 and is used to drive the drilling mechanism 200 to rotate. The second gear 122 is connected to the guide mechanism 400 and is used to drive the drilling mechanism 200 to move up and down along the axial direction of the guide mechanism 400.

[0075] In this embodiment, considering the stability of the transmission, the gear set 120 also includes a plurality of transmission gears 123, such as Figure 2 As shown, the drive motor 110 simultaneously drives the first gear 121 and the second gear 122 through the transmission gear 123 to complete the transmission.

[0076] For example, when the drive motor 110, the first gear 121, and the second gear 122 are connected in sequence, transmission gears 123 are arranged between the drive motor 110 and the first gear 121, and between the first gear 121 and the second gear 122.

[0077] For example, the drive mechanism 100 also includes a reducer 130, such as Figure 2 As shown, the input end of the reducer 130 is connected to the first gear 121, and the output end of the reducer 130 is connected to the drilling mechanism 200, thereby driving the rotation of the drilling mechanism 200. More specifically: In this embodiment, the input end of the reducer 130 is a gear input, and the input gear on the reducer 130 meshes with the first gear 121 to achieve transmission. The output end of the reducer 130 is fixedly connected to the drill bit 210, and the rotation of the reducer output end is directly transmitted to the drill bit 210.

[0078] In this embodiment, the ratio of the lead of the helical blade 220 on the drill bit 210 to the lead of the lead screw 410 is equal to the reduction ratio of the reducer 130. This ensures that when the drive motor 110 is working, the lifting and lowering of the mounting box along the lead screw 410 and the working lead of the drill bit 210 cutting the sand are matched, that is, ensuring the coordination of the lifting and rotating actions, so as to minimize the shear force on the helical blade 220 when cutting the sand. For example, in this embodiment, the lead screw 410 is preferably a ball screw with a lead of 5mm, the lead of the helical blade 220 on the drill bit 210 is 150mm, and the reduction ratio of the reducer 130 is 30. The reducer 130 is preferably an RV reducer.

[0079] In this embodiment, the reducer 130 has a hollow structure, and the hollow structure corresponds to the hollow cavity, so that the seedlings to be planted can be put into the hollow cavity.

[0080] Compared to existing independent lifting and rotating controls for hole-digging drill bits, the drive mechanism 100 in this embodiment includes only one drive motor 110. By using only one drive motor 110 to synchronize the rotation and lifting operations of the drilling mechanism 200, it not only offers advantages such as high synchronization, high stability, and simple control, but also reduces the overall weight of the hole-digging device Z1. Specifically, because the drive mechanism 100 in this embodiment can achieve synchronized rotation and lifting of the drill bit 210 through the bidirectional rotating drive motor 110, there is no need to consider the synchronization of lifting and rotating operations. Reducing the number of motors inevitably reduces weight, thus lowering the load-bearing requirements on the mobile support chassis of the hole-digging device.

[0081] In some specific embodiments of the present invention, the drilling mechanism 200 is used on the one hand to dig planting holes, and on the other hand to provide a channel for seedlings or seeds to be planted into the planting holes. The drilling mechanism 200 includes a drill bit 210 and spiral blades 220 arranged on the outer wall of the drill bit 210. Along the length direction of the drill bit 210, a hollow cavity is provided inside the drill bit 210, which serves as a channel for the seedlings or seeds to be moved into the planting holes.

[0082] Furthermore, the drill bit 210 also includes a drill rod 211, such as Figure 3 As shown, the drill rod 211 is movably connected to the opening / closing end 212. The drill rod 211 is connected to the drive mechanism 100 and is driven by the drive mechanism 100 to perform rotational and lifting movements. The opening / closing end 212 is used to open the tip of the drill bit 210, facilitating the falling of seedlings or seeds into the planting hole. Along the length of the drill rod 211, a first cavity is provided inside the drill rod 211, and a second cavity is provided inside the opening / closing end 212. The first cavity and the second cavity communicate to form a hollow cavity.

[0083] In this embodiment, the opening and closing end 212 solves the problem that during the drilling process of the drilling mechanism 200, sand can easily clog the lower opening of the drill rod 211, preventing seedlings or seeds from falling into the planting hole. Simultaneously, to facilitate the insertion of the drill bit 210 into the sand and improve digging, the opening and closing end 212 is designed as a conical structure when closed. This conical structure includes multiple petals 2121, such as... Figure 3 As shown, multiple petals 2121 close to form a conical structure with a second cavity. When multiple petals 2121 are in the open state, they provide a channel for the seedlings or seeds to enter the planting hole.

[0084] Furthermore, the helical blade 220 is disposed on the outer wall of the drill pipe 211.

[0085] In some specific embodiments of the present invention, during the excavation process of the drilling mechanism 200, in order to ensure the excavation process is smooth and to prevent sand from entering the first cavity, so as to facilitate the seedlings to enter the planting hole smoothly, the digging device of this embodiment also includes an opening and closing control mechanism 300.

[0086] Furthermore, the opening and closing control mechanism 300 includes an opening and closing drive component, a connecting disc, and a pulling component connected in sequence. The pulling component is a non-elastic component of fixed length. The first end of the pulling component is connected to the opening and closing drive component, and the second end passes through the spiral blade 220 and is fixedly connected to the petal 2121 in the opening and closing end 212. The opening and closing drive component is fixedly connected to the drill rod 211.

[0087] Furthermore, the traction components are configured in a one-to-one correspondence with the valve bodies 2121, with one traction component connecting to one valve body 2121, and one traction component controlling the opening and closing of one valve body 2121.

[0088] Furthermore, the opening and closing drive component is preferably a telescopic drive mechanism.

[0089] In some specific embodiments of the present invention, in order to make the lifting direction of the drilling mechanism 200 more accurate, the drilling device further includes a guide mechanism 400, which is connected to the second gear 122. Specifically, the guide mechanism 400 includes a lead screw 410 and a lead screw nut, which are fixedly connected to the second gear 122.

[0090] In this embodiment, to make the drilling mechanism 200 more stable during the lifting process, two sets of guide mechanisms 400 are provided, and two second gears are provided. The two sets of guide mechanisms 400 are arranged symmetrically with respect to the drilling mechanism 200.

[0091] In this embodiment, the lead screw 410 is a ball screw. The lead screw 410 is fixed and does not rotate. The lead screw nut on the lead screw 410 is fixedly connected to the second gear. Therefore, when the second gear rotates, the lead screw nut rotates at the same time, so that the entire mounting box 600 can move up and down.

[0092] In some specific embodiments of the present invention, considering the support of the drive mechanism 100, drilling mechanism 200, opening and closing control mechanism 300, and guide mechanism 400 in the hole-digging device, the hole-digging device also includes a support frame 500 and a mounting box 600, such as... Figure 1 As shown, the mounting box 600 is disposed within the support frame 500. The mounting box 600 is fixedly connected to the drive mechanism 100, the drive mechanism 100 is connected to the drilling mechanism 200, the guide mechanism 400 is fixedly connected to the support frame 500, and the guide mechanism 400 is connected to the mounting box 600.

[0093] For example, the drive motor 110 in the drive mechanism 100 is fixedly connected to the mounting box 600, and the gear set 120 and reducer 130 in the drive mechanism 100 are disposed in the inner cavity of the mounting box 600 and fixedly connected to the mounting box 600. Positioning bearings are installed above and below each gear in the gear set 120, so that the radial plane of the bearings always maintains the same height as the mounting box 600. The positioning bearings are preferably tapered roller bearings.

[0094] The lead screw 410 in the guide mechanism 400 is fixedly connected to the support frame 500, and the lead screw nut 420 is located in the mounting box 600 and connected to the second gear 122.

[0095] Considering that the drilling mechanism 200 needs to perform digging operations, a first through hole is provided at the bottom of the support frame 500 to facilitate the passage of the drill bit 210; considering that seedlings need to be filled into the drilling mechanism 200, a second through hole is provided at the top of the support frame 500, and the second through hole is set opposite to the open opening.

[0096] Example 2

[0097] One embodiment of the present invention discloses a planting machine, such as Figure 4 As shown, it includes a hole-digging device Z1 and a storage, transport, and compaction device Z2 as described in Example 1. The hole-digging device Z1 includes a hollow cavity through which the seedlings to be planted enter the planting hole. The storage, transport, and compaction device Z2 is used to store the seedlings or seeds to be planted and to move the seedlings or seeds into the hollow cavity.

[0098] The planting machine in this embodiment also includes a mobile support chassis Z3, which is used to support and move the hole-digging device Z1 and the storage, transportation, and compaction device Z2.

[0099] In this embodiment, the storage and compaction device Z2 includes a storage component Z2-100, a driving component Z2-200, a planting component Z2-300, and detachable components, such as... Figure 4As shown, the storage component Z2-100 includes a seed storage component Z2-120 for storing seeds or seedlings to be planted; the driving component Z2-200 is used to drive the seed storage component Z2-120 to move towards the planting component Z2-300; the planting component Z2-300 includes a pressing head Z2-310, which is used to put the seeds or seedlings opposite to it from the seed storage component Z2-120 into the hollow cavity of the hole-digging device Z1. The storage component Z2-100 and the driving component Z2-200 are detachably connected through a detachable component.

[0100] The storage component Z2-100 includes, in sequence, a first fixed disk Z2-110, a storage component Z2-120, a second fixed disk Z2-130, a sponge paper Z2-140, and a limiting disk Z2-150, as follows: Figure 5 As shown, the upper part of the seed storage component Z2-120 is fixedly connected to the first fixing plate Z2-110, and the lower part of the seed storage component Z2-120 is fixedly connected to the second fixing plate Z2-130. The second fixing plate Z2-130 is detachably connected to the limiting plate Z2-150, allowing the sponge paper Z2-140 to be replaced through disassembly and reassembly. The storage component Z2-100 also includes a through hole Z2-160, which sequentially passes through the first fixing plate Z2-110, the seed storage component Z2-120, the second fixing plate Z2-130, and the limiting plate Z2-150. When the seed storage component Z2-120 stores or transports seeds or seedlings, the seeds or seedlings are placed inside the through hole Z2-160 and positioned above the sponge paper Z2-140.

[0101] The drive component Z2-200 includes a linear drive assembly Z2-210, a connecting block Z2-230, and a rotary drive assembly Z2-220 connected in sequence, such as... Figure 8 As shown. This embodiment realizes the linear translation and rotational movement of the storage chamber Z2-1211 based on the linear drive assembly Z2-210 and the rotary drive assembly Z2-220. In this embodiment, the linear drive assembly Z2-210 includes a base Z2-211, a drive screw, a drive screw nut, a groove, a slider Z2-212, a linear drive motor Z2-213, and a guide Z2-214. The slider Z2-212 includes a protrusion, such as... Figure 9As shown; the drive screw is arranged along the length of the base Z2-211; the drive screw nut is screwed to the drive screw; the slider Z2-212 is fixedly connected to the drive screw nut, a groove is provided on the base Z2-211, the groove matches the protrusion on the slider Z2-212, the slider Z2-212 is slidably connected to the groove, the linear drive motor Z2-213 is connected to the drive screw to make the drive screw rotate, the guide Z2-214 is provided on the base Z2-211, and the slider Z2-212 is provided with a mounting groove that matches the guide Z2-214 to ensure the accuracy of the sliding direction of the slider Z2-212. The rotary drive assembly Z2-220 includes a rotary drive motor Z2-221 and a hollow rotary platform Z2-222 connected in sequence. The hollow rotary platform Z2-222 includes a rotating component, such as... Figure 8 As shown, the rotating component Z2-2221 is used to drive the storage component Z2-100 to rotate.

[0102] The planting component Z2-300 includes a pressure head Z2-310, a retractable drive assembly Z2-320, and a support component Z2-330, such as Figure 10 As shown, the retractable drive assembly Z2-320 includes a flexible telescopic component Z2-321, a flexible telescopic component storage box Z2-322, an active friction wheel Z2-323, and a driven wheel Z2-324. A gap is provided between the active friction wheel Z2-323 and the driven wheel Z2-324. A drum is provided in the flexible telescopic component storage box Z2-322. The fixed end of the flexible telescopic component Z2-321 is fixed to the drum, and the free end of the flexible telescopic component Z2-321 extends out of the flexible telescopic component storage box Z2-322 and the gap in sequence, and then connects to the pressure head Z2-310. The flexible telescopic component Z2-321 is clamped by the pre-tightening force of the active friction wheel Z2-323 and the driven wheel Z2-324. The active friction wheel Z2-323 drives the flexible telescopic component Z2-321 to perform scaling movements, thereby enabling the flexible telescopic component Z2-321 to drive the pressure head Z2-310 to press down and retract. The support component Z2-330 includes a fixed plate Z2-331, a flexible telescopic component storage box Z2-322, an active friction wheel Z2-323, a driven wheel Z2-324, and a stepper motor Z2-325, all of which are fixedly connected to the fixed plate Z2-331.

[0103] The detachable components include a plug Z2-410 and a slot Z2-420. The plug Z2-410 is located on the drive component Z2-200, and the slot Z2-420 is located at the bottom of the storage component Z2-100, as shown below. Figure 6 and Figure 8As shown. More specifically, plug Z2-410 connects to rotating component Z2-2221 in hollow rotating platform Z2-222. Slot Z2-420 is located in the middle of second fixed plate Z2-130. To ensure a stable connection, slot Z2-420 is configured as a socket that penetrates both limiting plate Z2-150 and second fixed plate Z2-130.

[0104] In this embodiment, a rollable flexible telescopic component Z2-321 is used to push seedlings or seeds out of the storage chamber Z2-1211. The rollable flexible telescopic component Z2-321 significantly reduces the overall height of the storage, transportation, and compaction mechanism in this embodiment, significantly reduces the installation space occupied by the planting component Z2-300, and increases the passability and safety of the storage, transportation, and compaction mechanism in this embodiment during operation.

[0105] In this embodiment, compared to existing compaction and transfer machines, the compaction and storage mechanism ensures that the seedlings or seeds remain relatively stationary with the sponge paper Z2-140 during the process of moving them into the hollow cavity. Specifically, the seedlings or seeds remain stationary with the seed storage component Z2-120, preventing damage to the seed coat and seedling roots. In this embodiment, the sponge paper Z2-140 supports and prevents seeds or seedlings from falling out of the lower opening of the seed storage component Z2-120.

[0106] In this embodiment, the planting component Z2-300 is used to move the seeds or seedlings from the storage chamber Z2-1211 located directly below it to the planting hole. Specifically, the seeds or seedlings are placed from the storage chamber Z2-1211 through the sponge paper Z2-140 and then into the hole-digging device Z1, specifically into the hollow cavity of the drill bit 210.

[0107] Furthermore, each storage chamber Z2-1211 stores one seedling or one or more seeds. To maximize the storage capacity of the storage component Z2-100 while minimizing space occupation and ensuring that the storage chambers Z2-1211 do not interfere with each other, the storage component Z2-100 is preferably designed as a cylindrical structure. It should be noted that the first fixing disk Z2-110 and the second fixing disk Z2-130 are arranged along the same central axis. When the storage component Z2-100 is cylindrical, the seed storage assembly Z2-120 includes storage units Z2-121. These storage units Z2-121 are arranged circumferentially around the central axis, with multiple layers arranged radially from the inside to the outside of the storage component Z2-100. Each storage unit Z2-121 includes multiple storage chambers Z2-1211, such as... Figure 5 and Figure 7 As shown, multiple storage chambers Z2-1211 are arranged consecutively. Preferably, each storage chamber Z2-1211 is a tubular structure, such as... Figure 7 As shown, the through hole of the tubular structure coincides with the through hole Z2-160.

[0108] In this embodiment, the storage component Z2-100 has a cylindrical structure, a large storage capacity, and occupies little space. Due to its low space requirements, it also places lower demands on the desert tree planting machine and its chassis, significantly reducing the cost and energy consumption of supporting the storage, transportation, and compaction mechanism chassis, making it highly practical. Furthermore, in this embodiment, each storage chamber Z2-1211 is independent and does not interfere with each other; that is, a malfunctioning storage chamber will not affect the normal use of other storage chambers, greatly improving the reliability and stability of the storage component.

[0109] Furthermore, the second fixing plate Z2-130 includes a first connecting member Z2-131, and the limiting plate Z2-150 includes a second connecting member Z2-151. The first connecting member Z2-131 and the second connecting member Z2-151 are detachably connected, such as... Figure 5 As shown.

[0110] Furthermore, considering the guiding of the reciprocating motion of the pressure head Z2-310, the support member Z2-330 also includes a limiting guide hole Z2-332, such as... Figure 11 As shown, the limiting guide hole Z2-332 is formed on the fixed plate Z2-331. In this embodiment, the free end of the flexible telescopic member Z2-321 extends sequentially out of the gap between the flexible telescopic member storage box Z2-322, the active friction wheel Z2-323 and the driven wheel Z2-324, and the limiting guide hole Z2-332 before connecting with the pressure head Z2-310.

[0111] Furthermore, considering the different heights of the storage components Z2-100, in order to shorten the displacement of the pressure head Z2-310 and facilitate energy saving, the support component Z2-330 also includes a lifting component. The lifting component controls the rise and fall of the fixed plate Z2-331 through the lifting component, so that the height of the pressure head Z2-310 matches the height of the storage components Z2-100.

[0112] Furthermore, to prevent damage to the seedling when pressing down on it, a flexible layer is provided on the side of the pressing head Z2-310 facing the seedling. The flexible layer includes a flexible material.

[0113] Furthermore, when pressing down on the seeds, the pressure head Z2-310 has an opening on the side facing the seeds. This ensures that when the pressure head Z2-310 contacts the sponge paper Z2-140, a cavity is formed through the opening to accommodate the seeds. Figure 12 As shown, this is to ensure that the Z2-310 pressure head does not damage the seeds during the downward movement of the pressure head Z2-310 and the process of pushing the seeds into the planting hole.

[0114] It should be noted that: to ensure the Z2-310 pressure head can quickly cut the sponge paper, the opening includes a blade portion, which is located on the outer edge of the opening, such as... Figure 12 As shown.

[0115] Furthermore, considering that the pressure head Z2-310 may experience intermittent interruptions during the cutting of the sponge paper Z2-140, resulting in seeds failing to fall from the storage chamber Z2-1211, the planting component Z2-300 also includes a planting rotation assembly. The planting rotation assembly is connected to the support Z2-330 and drives the fixed plate Z2-331 to rotate, thereby causing the pressure head Z2-310 to rotate.

[0116] More specifically, the planting rotation assembly includes a planting drive motor, a first rotating gear, and a second rotating gear connected in sequence. The planting drive motor is fixedly connected to the support member Z2-330, and the second rotating gear is fixedly connected to the fixed plate Z2-331 to drive the fixed plate Z2-331 to rotate.

[0117] It should be noted that when the pressure head Z2-310 comes into contact with the sponge paper Z2-140, the pressure head Z2-310 is rotating. The blade on the pressure head Z2-310 rotates and cuts the sponge paper Z2-140, and the pressure head Z2-310 completely cuts the sponge paper Z2-140, which facilitates the seeds falling into the planting hole.

[0118] Example 3

[0119] One embodiment of the present invention discloses a method for planting seedlings based on the planting machine described in Embodiment 2, such as... Figure 13 As shown, it includes:

[0120] S1, the drilling mechanism 200 rotates and digs down to obtain a planting hole;

[0121] S2, the drilling mechanism 200 moves upward a certain distance and then stops moving;

[0122] S3, control the opening of the valve body 2121, and the seedling or seed located inside the drilling mechanism 200 falls into the planting hole;

[0123] S4, the drilling mechanism 200 continues to move upward until it is reset. During this process, the control valve 2121 remains open until the seedling is completely separated from the drilling mechanism 200, the valve 2121 is reset, and it returns to S1.

[0124] In some specific embodiments of the present invention, S1 includes: the drive motor 110 rotates forward, driving the drilling mechanism 200 to move toward the target planting hole through the gear set 120, and at the same time, driving the drilling mechanism 200 to rotate until the distance of descent is the depth of the planting hole, the drive motor 110 stops driving, and the drilling mechanism 200 stops moving.

[0125] More specifically, the drive motor 110 rotates forward, and the output shaft transmits the rotational torque through the gear set 120, causing the gear connected to the lead screw nut to follow the rotation, making the lead screw nut rotate on the lead screw 410, driving the entire mounting box 600 to move downward; the input gear of the reducer 130 rotates, and the speed and torque are transmitted to the drill bit 210 through the reduction effect of the reducer 130, so that the mounting box 600 moves downward while the drill bit 210 rotates at a differential speed; throughout the entire digging process, the opening and closing end on the drill bit 210 remains closed, thus realizing the digging device Z1 digging with seedlings.

[0126] In some specific embodiments of the present invention, S2 includes: the drive motor 110 reverses and drives the drilling mechanism 200 to rotate and move upward by a distance L1 through the gear set 120; the drive motor 110 stops driving and the drilling mechanism 200 stops moving; wherein L1 is greater than or equal to the vertical length of the valve body 2121 so that the opening process of the valve body 2121 is smooth.

[0127] In more detail, the drive motor 110 reverses, and the drill bit 210 is lifted. The transmission method of motor speed and torque is the same as in the digging process. While the drill bit 210 reverses, it moves upward. The opening and closing control mechanism 300 controls the opening and closing end to unfold. At this time, the sapling inside the hollow drill bit is naturally left in the sand due to gravity. Due to the fluidity of the desert sand, the sand naturally backfills during the drill bit's ascent, completing the planting of the sapling.

[0128] In some specific embodiments of the present invention, S3 includes:

[0129] S31, the opening and closing drive component shortens and starts, driving the pulling component to move upward, so that the valve body 2121 opens;

[0130] S32, all the petals 2121 are in the open state. At this time, the opening and closing ends of the drill bit 210 are in the open state, and the seedlings or seeds in the hollow cavity of the drill bit 210 fall into the planting hole.

[0131] In some specific embodiments of the present invention, the resetting of the valve body 2121 in S4 includes: the opening and closing drive member extends and starts, driving the pulling member to move down, canceling the stretching of the pulling member on the valve body 2121, the valve body 2121 is reset, and the closure of the opening and closing end is completed.

[0132] It should be noted that during the tree planting process, water is simultaneously poured from the seedling placement hole at the top of the installation box 600 according to the characteristics of different tree species. The seedling placement hole is set opposite to the upper opening of the hollow cavity of the drill bit 210. The water outlet of the watering device is directly connected to the side of the seedling placement hole through a plastic water pipe, so that water can be poured and moistened at different depths during the tree planting process, effectively improving the survival rate of seedlings.

[0133] Example 4

[0134] The difference between this embodiment and embodiment 3 is that, at least before S3, it includes using the storage and pressing device Z2 to press the seedling or seed into the hollow cavity, such as... Figure 14 As shown:

[0135] A1, the pressure head Z2-310 is opposite to the inlet of the hollow cavity;

[0136] A2. Determine whether all the seedlings in storage component Z2-100 have been removed. If yes, proceed to A3; otherwise, proceed to A4.

[0137] A3, replace the storage component Z2-100 that is full of seedlings, then proceed to A4;

[0138] A4, the linear drive component Z2-210 drives the storage component Z2-100 to move in the direction of the pressure head Z2-310 until the storage unit Z2-121 on the storage component Z2-100 moves directly below the pressure head Z2-310;

[0139] A5, the rotary drive assembly Z2-220 drives the storage component Z2-100 to rotate until the upper opening of the storage chamber Z2-1211 in the storage unit Z2-121 is directly facing the pressure head Z2-310. The storage chamber Z2-1211 contains seedlings or seeds.

[0140] A6, the pressure head Z2-310 begins the downward pressure and dispensing operation, including:

[0141] The active friction wheel Z2-323 and the driven wheel Z2-324 rotate forward to drive the pressure head Z2-310 to move towards the lower opening of the storage chamber Z2-1211 until the seedlings or seeds in the storage chamber Z2-1211 are removed from the storage chamber Z2-1211.

[0142] A7, pressure head Z2-310 reset, including:

[0143] The active friction wheel Z2-323 and the driven wheel Z2-324 reverse to drive the pressure head Z2-310 to retract, so that the pressure head Z2-310 moves out of the storage chamber Z2-1211. The pressure head Z2-310 is reset to its initial position, completing the reset of the pressure head Z2-310. Then, it returns to A2 and begins the next pressing and dispensing operation.

[0144] A8 determines whether to continue placing seedlings or seeds. If yes, return to A2 and start the next pressing and placing operation; otherwise, end the pressing and placing operation.

[0145] In this embodiment, the pressing operation is initiated from the outermost storage unit Z2-121 until all the seedlings in the innermost storage unit are pressed out.

[0146] In this embodiment, multiple storage components Z2-100 are provided. During the pressing and dispensing operation, while one storage component Z2-100 is always in the pressing and dispensing operation, at least one of the remaining storage components Z2-100 is in the state of storing seedlings, which significantly improves the efficiency of pressing and planting. Since all components of the storage component Z2-100 except for the sponge paper can be reused, costs are saved.

[0147] In this embodiment, after A3, it also includes: B1, the operation of replacing the sponge paper in the storage component Z2-100 after use. More detailed description: After the seedlings or seeds in each storage chamber Z2-1211 of the storage component Z2-100 are completely placed, the connection between the first connector Z2-131 and the second connector Z2-151 is released, the sponge paper full of holes, that is, the used sponge paper, is removed, and another brand new sponge paper is placed between the second fixing plate Z2-130 and the limiting plate Z2-150 to complete the connection between the first connector Z2-131 and the second connector Z2-151, and the lower opening of the storage chamber Z2-1211 is sealed, waiting for the seedlings to be filled.

[0148] In this embodiment, when the storage component Z2-100 has a cylindrical structure and the storage unit Z2-121 has two or more layers, A4 and A5 provide a more detailed explanation: The linear drive component Z2-210 drives the storage component Z2-100 to move towards the planting component Z2-300, so that the storage chamber Z2-1211 in any layer of storage unit Z2-121 is opposite to the pressure head Z2-310, and the linear drive component Z2-210 stops driving; when it is necessary to replace the storage chamber Z2-1211, the rotary drive component Z2-220 is activated, thereby driving the storage component Z2-100 to rotate, so as to replace the next storage chamber Z2-1211 until it is opposite to the pressure head Z2-310. That is, the movement of the storage chamber Z2-1211 and its relative positioning with the pressure head Z2-310 are completed by the linear drive component Z2-210 and the rotary drive component Z2-220.

[0149] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
