Description

Technical Field

[0001] This invention specifically relates to the field of planting technology, and more specifically to a tea seedling propagation and planting device. Background Technology

[0002] The core of tea seedling cultivation is to obtain them through sexual reproduction (seed propagation) or asexual reproduction (cutting, grafting, etc.). Cutting propagation can maintain the excellent traits of the mother tree. Tea seedlings are collectively propagated in a seedling greenhouse. With reasonable temperature and humidity and timely nutrient tracking, the tea seedlings grow rapidly. Once the planted tea trees have grown seedlings, they are transplanted to the ground.

[0003] Chinese Patent Application No. 202210420118.4 discloses an intelligent transplanting and planting device for tea trees, including a movable frame, an execution conveying device disposed within the movable frame for conveying tea trees, and a placement device disposed at the rear of the movable frame for placing the tea trees. This device solves the problems of existing methods where tea seedlings are manually placed into planting pits during transplanting, resulting in low efficiency and the prolonged exposure of the yellow mud covering the seedling roots to the outside, causing rapid dehydration and solidification, thus affecting the survival rate of the tea trees after planting. Furthermore, current planting machinery cannot automatically and uniformly adjust according to the spacing of the tea tree plantings; when different spacings of tea tree seedlings need to be planted, manual adjustment is still required, which is complex and technically challenging.

[0004] However, although the tea tree planting equipment in the aforementioned patent can automatically plant tea tree seedlings in the soil, the equipment requires manual pushing or pulling on uneven land during operation. It has to stop after moving forward a certain distance, and the small moving wheels are difficult to move on the land, which increases the difficulty of planting tea tree seedlings and increases the intensity of manual labor. Furthermore, it cannot achieve the effects of rapid planting and purely mechanized production. Summary of the Invention

[0005] The purpose of this invention is to provide a tea seedling propagation and planting device. The device is driven by a tractor and can sequentially place tea seedlings into a conical feeder. During the circulation of the conical feeder, a baffle on the mounting frame contacts an L-shaped block on the outer wall of the movable conical shell, opening both the fixed and movable conical shells. The tea seedlings then fall into a rotating feeding frame below. When one of the contact bearings on either side of the feeding frame contacts an arc-shaped protrusion on the inner wall of the outer side plate, the first and second planting shells move laterally through toothed engagement, effectively opening the soil at the planting location and allowing the tea seedlings to be effectively inserted into the soil. This greatly improves the mechanization of the equipment, reduces manual labor intensity, and increases the planting efficiency of tea seedlings, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A tea seedling propagation and planting device includes a tractor; the tractor is installed in conjunction with a tractor unit; the tractor unit has a feeding mechanism and a planting mechanism installed inside; wherein, the top of the tractor unit is provided with two symmetrically arranged placement platforms; the feeding mechanism is located between the two placement platforms; the feeding mechanism includes a mounting frame; multiple conical feeders are provided on both sides of the mounting frame; a circulating chain is installed at the bottom of the mounting frame through a hanger and a sprocket assembly; the conical feeders are fixedly installed to the circulating chain through connecting plates; the conical...

After the L-shaped block separates from the baffle, the bottom of the fixed conical shell and the movable conical shell is closed by the torsion spring set between them, thereby effectively preventing the planted branches inside the conical feeder from falling out.

[0008] The feeding mechanism has a planting mechanism at its bottom; the planting mechanism includes two symmetrical outer plates; one of the outer plates has an integrally formed arc-shaped protrusion strip inside; the tops of the two outer plates are fixedly installed to the bottom of the placement platform; a main shaft is installed between the two outer plates through bearings; a turntable is installed on the main shaft, and multiple hanging plates are arranged in a circular array around the turntable; a material dropping frame is movably connected to the outside of each hanging plate; a first planting shell and a second planting shell are movably installed on both sides of the bottom of the material dropping frame; during the circulation of the first and second planting shells driven by the material dropping frame, the contact bearing at the top of one of the planting shells is in contact with the arc-shaped protrusion strip, so that the two planting shells effectively spread the soil, thereby facilitating the planting of branches.

[0010] As a further technical solution of the present invention, the bottom of the boom is fixedly installed with the protective plate; a first bevel tooth is fixedly installed at the bottom of the sprocket assembly at one end of the boom; the first bevel tooth and a second bevel tooth are meshed and connected; a drive sprocket is also coaxially arranged on the second bevel tooth; the shaft on which the second bevel tooth and the drive sprocket are mounted is movably installed with the protective plate through bearings; the meshing between the second bevel tooth and the first bevel tooth is achieved by the drive sprocket, so that the sprocket assembly inside the boom can achieve the effect of cyclic transmission of multiple conical feeders through a circulating chain;

[0011] As a further technical solution of the present invention, the drive sprocket is connected to the second driven sprocket on the main shaft via a chain; the main shaft is also provided with a first driven sprocket; the first driven sprocket is connected to the drive sprocket via a drive chain; the drive sprocket is installed on the drive shaft between the two traveling wheels; the drive sprocket realizes the rotation of the main shaft through the drive chain, realizing the synchronous circulation effect of the planting mechanism and the feeding mechanism, thereby effectively ensuring the cooperation between the conical feeder and the dropping frame, thereby effectively ensuring the quality and efficiency of planting.

[0012] As a further technical solution of the present invention, the bottom of the tractor is installed in conjunction with the traveling wheels; the tractor also includes two C-shaped guardrails; a ladder is fixedly installed at one end of the frame; a step is also provided at the bottom of the two placement platforms; the step is fixedly installed with the frame; a passageway is fixedly installed at one end of the two steps, and a storage platform is provided at the other end; the frame is detachably installed with the tractor via the tractor frame, the ladder facilitates climbing by workers, the storage platform effectively collects the pallets, and the C-shaped guardrails effectively protect the pallets and workers;

[0013] As a further technical solution of the present invention, the conical feeder on one side of the baffle installed on the mounting frame is on the same cross-section as the dropping frame; an L-shaped block is fixedly installed on the side wall of the movable conical shell, and the L-shaped block cooperates with the baffle; after the baffle opens the movable conical shell of the installed L-shaped block, the planting branch can be accurately dropped into the corresponding dropping frame.

[0014] As a further technical solution of the present invention, an arc-shaped protrusion strip is provided on the inner side of the outer side plate; the arc-shaped protrusion strip cooperates with the contact bearing at the top of the second implantation shell; the arc-shaped protrusion strip is on the circulation trajectory of the contact bearing; this effectively ensures that during the circulation of the material drop frame and the two implantation shells at the bottom, the contact bearing on one of the implantation shells can effectively cooperate with the arc-shaped protrusion strip, thereby achieving the effect of opening the bottom of the two implantation shells.

[0015] As a further technical solution of the present invention, the protective plate is fixedly installed on the crossbeam on the frame body, and the top of the support rods at the four corners of the frame body is provided with a handwheel. By rotating the handwheel, the distance between the bottom of the frame body and the soil can be effectively adjusted, thereby effectively realizing the adjustment of the planting depth of the first planting shell and the second planting shell on the soil, so as to meet different planting needs.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In use, the tray containing tea tree seedlings is placed on a platform. The worker places the tea tree seedlings into the conical feeder on the platform. Through the cooperation between the sprocket assembly and the circulating chain, multiple conical feeders on both sides of the mounting frame are circulated and transported. During the circulation of the feeding mechanism, the planting mechanism performs effective circulatory planting simultaneously, so as to plant the tea tree seedlings into the soil.

[0018] 2. In this invention, when the walking wheels move, the active shaft between the two walking wheels drives the drive chain through the active sprocket to realize the first driven sprocket driving the main shaft to rotate. When the main shaft rotates, the hanging plate realizes the rotational planting between multiple material drop frames and the first planting shell and the second planting shell.

[0019] 3. In this invention, the second driven sprocket installed on the main shaft drives the drive sprocket to rotate via a chain, thereby achieving meshing between the second bevel tooth coaxially arranged on the drive sprocket and the first bevel tooth installed at the bottom of the sprocket assembly shaft. The sprocket assembly achieves cyclic transmission of the conical feeders on both sides of the mounting frame via a circulating chain. During the circulation of the conical feeders, when the L-shaped block on the side wall of the movable conical shell contacts the baffle on the mounting frame, the fixed conical shell and the movable conical shell are separated, thereby dropping the tea seedlings into the lower dropping frame. After the L-shaped block separates from the baffle, the torsion spring between the fixed conical shell and the movable conical shell achieves the effect of reset and closure.

[0020] 4. In the process of the planting mechanism circulation, when one set of planting structures moves downward, the first and second planting shells at the bottom of the material drop frame are inserted into the soil. As they move, the tops of the first and second planting shells contact the arc-shaped protrusion strip on the inner side of the outer plate through the contact bearing installed on the inclined column, so that one of the planting shells swings outward. At this time, the teeth between the first and second planting shells mesh with each other, thereby effectively moving the other planting shell in the opposite direction, thereby effectively opening up the soil. At this time, the tea tree seedlings inside the material drop frame fall into the planting position. After the contact bearing separates from the arc-shaped protrusion strip, the first and second planting shells close and reset under the action of the teeth.

[0021] 5. This invention; After the trays are placed on the placement platform on one side, the trays are collected on the storage table. The workers move to the sitting platform on the other side through the aisle board to effectively place the tea seedlings in the trays on the placement platform. This can effectively realize the continuous planting work of the equipment. When planting different varieties of tea seedlings, the distance between the bottom of the machine frame and the soil can be adjusted by rotating the handwheels installed on the four corners of the machine frame, thereby effectively realizing planting operations at different depths for different varieties.

[0022] 6. In this invention, the material feeding frame, the first planting shell, and the second planting shell together form a planting mechanism; multiple planting mechanisms are arranged in a circular array on the outside of the turntable; when planting tea trees, the specific number of planting mechanisms can be set according to the planting needs, thereby ensuring the density of the tea trees after planting.

[0044] The feeding mechanism 4 has a planting mechanism 6 at its bottom. The planting mechanism 6 includes two symmetrical outer plates 63. One of the outer plates 63 has an integrally formed arc-shaped protrusion 67 inside. The tops of the two outer plates 63 are fixedly installed to the bottom of the placement platform 22. A main shaft 61 is installed between the two outer plates 63 through bearings. A turntable is installed on the main shaft 61, and multiple hanging plates 62 are arranged in a circular array around the turntable. A material drop frame 64 is movably connected to the outside of each hanging plate 62. A first planting shell 65 and a second planting shell 66 are movably installed on the bottom sides of the material drop frame 64, respectively.

[0045] The tops of the first implant shell 65 and the second implant shell 66 are respectively movably mounted with contact bearings 69 via corresponding inclined columns 68; the first implant shell 65 and the second implant shell 66 are movably mounted with the support rods inside the hanging plate 62; the inner sides of both ends of the first implant shell 65 and the second implant shell 66 are respectively provided with interlocking teeth 610.

[0046] By adopting the above technical solution, when in use, the tray containing tea tree seedlings is placed on the placement platform 22, and the staff put the tea tree seedlings into the conical feeder 40 on the seat 23. Through the cooperation between the sprocket group 42 and the circulating chain 43, the multiple conical feeders 40 on both sides of the mounting frame 41 are circulated and transported. During the circulation of the feeding mechanism 4, the planting mechanism 6 simultaneously performs effective circulatory planting, so as to plant the tea tree seedlings into the soil.

[0047] Please see the appendix Figure 14-15 As a further explanation of the above embodiments, the material feeding frame 64, the first planting shell 65, and the second planting shell 66 together form a planting mechanism; multiple planting mechanisms are arranged in a circular array on the outside of the turntable;

[0048] When planting tea trees, the specific number of planting structures can be set according to planting needs to ensure the density of the tea trees after planting.

[0049] By adopting the above technical solutions, the spacing between tea trees can be ensured, guaranteeing sufficient growing space for the tea trees while also ensuring a high yield per acre.

[0050] Please see Figure 1-13 In this embodiment, the bottom of the boom 48 is fixedly installed with the protective plate 26; a first bevel tooth 410 is fixedly installed at the bottom of the shaft of the sprocket assembly 42 at one end of the boom 48; the first bevel tooth 410 is meshed with a second bevel tooth 411; a drive sprocket 49 is also coaxially arranged on the second bevel tooth 411; the shaft on which the second bevel tooth 411 and the drive sprocket 49 are mounted is movably installed with the protective plate 26 through bearings;

[0051] In this embodiment, the drive sprocket 49 is connected to the second driven sprocket 10 on the main shaft 61 via the chain 9; the main shaft 61 is also provided with a first driven sprocket 5; the first driven sprocket 5 is connected to the drive sprocket 8 via the drive chain 7; the drive sprocket 8 is mounted on the drive shaft 11 between the two traveling wheels 3;

[0052] By adopting the above technical solution, when the walking wheel 3 moves, the active rotating shaft 11 between the two walking wheels 3 drives the drive chain 7 through the active sprocket 8 to realize the first driven sprocket 5 driving the main shaft 61 to rotate. When the main shaft 61 rotates, the multiple dropping frames 64 and the rotation planting between the first planting shell 65 and the second planting shell 66 are realized through the hanging plate 62.

[0053] Furthermore, the second driven sprocket 10 installed on the main shaft 61 drives the drive sprocket 49 to rotate via the chain 9, thereby achieving meshing between the second bevel tooth 411 coaxially arranged on the drive sprocket 49 and the first bevel tooth 410 installed at the bottom of the sprocket assembly 42 shaft. The sprocket assembly 42 achieves cyclic transmission of the conical feeders 40 on both sides of the mounting frame 41 via the circulating chain 43. During the circulation of the conical feeders 40, when the L-shaped block 46 on the side wall of the movable conical shell 45 contacts the baffle 47 on the mounting frame 41, the fixed conical shell 44 and the movable conical shell 45 are separated, thereby dropping the tea seedlings into the lower dropping frame 64. After the L-shaped block 46 separates from the baffle 47, the torsion spring between the fixed conical shell 44 and the movable conical shell 45 achieves the effect of reset and closure.

[0054] In this embodiment, the bottom of the tractor 2 is fitted with the traveling wheels 3; the tractor 2 also includes two C-shaped guardrails 24; a ladder 25 is fixedly installed at one end of the frame body 21; the bottom of the two placement platforms 22 is also provided with a step 27; the step 27 is fixedly installed with the frame body 21; a passageway 28 is fixedly installed at one end of the two steps 27, and a storage platform 20 is provided at the other end; the frame body 21 is detachably installed with the tractor 1 via a towing frame 29; the ladder 25 effectively facilitates the climbing of workers; the passageway 28 effectively ensures safety when alternating between the two placement platforms 22;

[0055] The conical feeder 40 on one side of the baffle 47 installed on the mounting frame 41 is on the same cross section as the dropping frame 64; an L-shaped block 46 is fixedly installed on the side wall of the movable conical shell 45, and the L-shaped block 46 cooperates with the baffle 47.

[0056] By adopting the above technical solution, during the cycle of the planting mechanism 6, when one set of planting structures moves downward, the first planting shell 65 and the second planting shell 66, which are closed at the bottom of the material drop frame 64, are inserted into the soil. As they move, the tops of the first planting shell 65 and the second planting shell 66 contact the arc-shaped protrusion 67 on the inner side of the outer plate 63 through the contact bearing 69 installed by the inclined column 68, so that one of the planting shells swings outward. At this time, the teeth 610 between the first planting shell 65 and the second planting shell 66 mesh with each other, thereby effectively moving the other planting shell in the opposite direction, thus effectively opening up the soil. At this time, the tea tree seedlings inside the material drop frame 64 fall into the planting position. After the contact bearing 69 separates from the arc-shaped protrusion 67, the first planting shell 65 and the second planting shell 66 close and reset under the action of the teeth 610.

[0057] In this embodiment, an arc-shaped protrusion 67 is provided on the inner side of the outer side plate 63; the arc-shaped protrusion 67 cooperates with the contact bearing 69 at the top of the second planting shell 66; the arc-shaped protrusion 67 is on the cyclic trajectory of the contact bearing 69; effectively ensuring the cooperation between the contact bearing 69 and the arc-shaped protrusion 67, thereby ensuring the quality of planting;

[0058] The protective plate 26 is fixedly installed on the crossbeam on the frame body 21, and handwheels are provided on the top of the support rods at the four corners of the frame body 21;

[0059] By adopting the above technical solution, after the trays are placed on the placement platform 22 on one side, the trays are collected on the storage platform 20. The staff can then move to the seating platform 23 on the other side via the aisle 28 to effectively place the tea seedlings in the trays on the placement platform 22. This can effectively achieve continuous planting work of the equipment.

[0060] Furthermore, when planting seedlings of different varieties of tea trees, the distance between the bottom of the machine frame 21 and the soil can be adjusted by rotating the handwheels installed on the four corners of the machine frame 21, thereby effectively realizing planting operations of different varieties at different depths.

[0061] The working principle of this invention is as follows: When in use, a tray containing tea tree seedlings is placed on the placement platform 22. The operator places the tea tree seedlings into the conical feeder 40 from the seat 23. Through the cooperation between the sprocket group 42 and the circulating chain 43, the multiple conical feeders 40 on both sides of the mounting frame 41 are circulated and transported. During the circulation of the feeding mechanism 4, the planting mechanism 6 simultaneously performs effective circulatory planting, thereby planting the tea tree seedlings into the soil.

[0062] When the walking wheels 3 move, the drive shaft 11 between the two walking wheels 3 drives the drive chain 7 through the drive sprocket 8, thereby enabling the first driven sprocket 5 to drive the main shaft 61 to rotate. When the main shaft 61 rotates, the hanging plate 62 enables the rotational planting between multiple material drop frames 64 and the first planting shell 65 and the second planting shell 66.

[0063] Meanwhile, the second driven sprocket 10 installed on the main shaft 61 drives the drive sprocket 49 to rotate through the chain 9, realizing the meshing between the second bevel tooth 411 coaxially set on the drive sprocket 49 and the first bevel tooth 410 installed at the bottom of the sprocket assembly 42 shaft. The sprocket assembly 42 realizes the cyclic transmission of the conical feeders 40 on both sides of the mounting frame 41 through the circulating chain 43. During the circulation of the conical feeder 40, when the L-shaped block 46 on the side wall of the movable conical shell 45 contacts the baffle 47 on the mounting frame 41, the fixed conical shell 44 and the movable conical shell 45 are separated, so that the tea seedlings fall into the dropping frame 64 below. After the L-shaped block 46 separates from the baffle 47, the torsion spring between the fixed conical shell 44 and the movable conical shell 45 realizes the effect of reset and closure.

[0064] During the cycle of the planting mechanism 6, when one of the planting structures moves downward, the first planting shell 65 and the second planting shell 66, which are closed at the bottom of the material drop box 64, are inserted into the soil. As they move, the tops of the first planting shell 65 and the second planting shell 66 contact the arc-shaped protrusion strip 67 on the inner side of the outer plate 63 through the contact bearing 69 installed by the inclined column 68, so that one of the planting shells swings outward. At this time, the teeth 610 between the first planting shell 65 and the second planting shell 66 mesh with each other, thereby effectively moving the other planting shell in the opposite direction, thus effectively opening up the soil. At this time, the tea tree seedlings inside the material drop box 64 fall into the planting position. After the contact bearing 69 separates from the arc-shaped protrusion strip 67, the first planting shell 65 and the second planting shell 66 close and reset under the action of the teeth 610.

[0065] After the trays are placed on the placement platform 22 on one side, they are collected on the storage table 20. The staff can then move to the seating platform 23 on the other side via the aisle 28 to effectively place the tea seedlings in the trays on the placement platform 22. This allows for continuous planting operations.

[0066] When planting seedlings of different varieties of tea trees, the distance between the bottom of the frame 21 and the soil can be adjusted by rotating the handwheels installed on the four corners of the frame 21, thereby effectively realizing planting operations of different varieties at different depths.
