Description

Technical Field

[0001] This invention relates to the field of machinery for planting Chinese medicinal herbs, and more specifically, to a self-propelled transplanter. Background Technology

[0002] The current method of planting Salvia miltiorrhiza mainly adopts root segment transplanting. Generally, large seedlings with a root diameter of 0.3 cm, more than 10 leaves, and a height of more than 10 cm are selected. The main root is cut into 2 cm lengths, and then double-row planting is carried out in the planting field after the ridges are prepared, with a certain row spacing. At present, most Salvia miltiorrhiza planting relies on manual transplanting, which is intensive and slow, making it difficult to meet the economic requirements of medicinal herb planting. On the other hand, the existing transplanting machinery is large and complex in structure, resulting in excessively high costs. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic transplanter to solve the problem that existing Salvia miltiorrhiza transplanting machinery is large in size and complex in structure, resulting in high cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A self-propelled transplanter includes: a frame, a first conveying mechanism, a second conveying mechanism, a seedling guide tube, and a movable component rotatably connected to the frame via a first rotating shaft. The first conveying mechanism, the second conveying mechanism, and the seedling guide tube are arranged vertically from top to bottom. The first conveying mechanism includes a slider and a slide rail slidably connected. A seedling cup is fixedly connected to the slider, and the slide rail is fixedly connected to the frame. The second conveying mechanism includes a sprocket mechanism and a seedling cup. The seedling cup is fixedly connected to the chain of the sprocket mechanism. The second conveying mechanism is rotatably connected to the frame via the sprocket mechanism, and the sprocket mechanism's rotating wheel is placed vertically. The seedling guide tube is fixedly connected to the frame and has a flared top structure. Both the sprocket mechanism and the slider are driven by a motor.

[0006] Existing transplanting machinery is large and complex, resulting in high costs. The present invention provides a self-propelled transplanter that uses a sliding rail slider mechanism, a sprocket mechanism, and a seedling guide tube as the main transmission components. The transplanted Salvia miltiorrhiza seedlings are transported by the above three mechanisms and moved in conjunction with the movement of the moving parts. This achieves mechanized planting of transplanted seedlings. Compared with existing large self-propelled transplanters, the structure is simpler, making transportation and transfer easier while reducing costs.

[0007] Furthermore, there are two of the second conveying mechanism and the slider, which are evenly distributed in the horizontal direction, and the number of seedling cups is several and evenly arranged.

[0008] Salvia miltiorrhiza is usually planted in two parallel rows on the same ridge. By setting two sliding parts in both the second and first conveyor mechanisms, the effect of parallel planting in two rows can be achieved. At the same time, the purpose of having a number of seedling cups evenly distributed is to ensure that the transplanted seedlings can be evenly and evenly placed as the second conveyor mechanism rotates, so as to facilitate the subsequent management and operation of the crop.

[0009] Furthermore, both the mouth of the seedling delivery cup and the mouth of the seedling receiving cup have a funnel-shaped structure.

[0010] By designing the seedling receiving cup and the seedling delivery cup into a funnel-shaped structure, the transplanting of Salvia miltiorrhiza seedlings is facilitated, while the top-in-bottom-out structure also prevents the seedlings from being upside down, which would affect planting.

[0011] Furthermore, the self-propelled transplanter also includes a root trimming mechanism, which includes a housing and a trimming plate connected to the inner wall of the housing. The trimming plate includes a plate body and a roller. The plate body is inclined downward in the vertical direction. The surface of the plate body has a number of square holes and the inside of the plate body has a cavity. The roller is rotatably connected to the cavity of the plate body. The roller is driven by a motor and the surface of the roller body is provided with blades. The number of blades is evenly distributed around the axis of the roller to form a blade group.

[0012] For root and rhizome crops like Salvia miltiorrhiza, pruning some roots before transplanting can promote root regeneration and taproot development. Newly regenerated roots can more effectively absorb water and nutrients from the soil. At the same time, appropriate root pruning can reduce the short-term water and nutrient requirements of the plant after transplanting, thereby improving its survival rate. The self-propelled transplanter provided by this invention uses a root pruning mechanism to automatically prune the roots of Salvia miltiorrhiza seedlings. When the seedling slides or rolls on the pruning plate, the fine roots enter the square holes and are pruned under the action of the rotating blades. At the same time, by setting the pruning plate at an angle, the seedling moves by its own weight, eliminating the need for an additional conveyor belt and achieving the purpose of simplifying the mechanism.

[0013] Furthermore, the number of blade groups is several and they are evenly distributed along the axial direction of the roller, and the side length of the square hole is less than 2cm.

[0014] For transplanted Salvia miltiorrhiza seedlings, only 2-3cm root segments are usually retained. By setting the side length of the square hole to less than 2cm, the root segments are prevented from falling directly into the square hole during the sliding / rolling process on the pruning board, which would damage the Salvia miltiorrhiza seedlings. Setting multiple sets of distributed blades can make the pruning more even.

[0015] Furthermore, the square hole is provided with a sloping anti-stopping block, which is fixedly connected to the lower edge of the square hole along the inclined direction of the plate.

[0016] To ensure that the cutter only trims the roots and does not damage the main root, the edge of the square hole has a certain thickness. During the sliding process of the transplanted seedling, there is a possibility that the roots may get stuck on the edge of the square hole. By setting the lower edge of the square hole on the inclined trimming board to be sloped, this can be prevented from the roots getting stuck on the edge of the square hole when the transplanted seedling slides.

[0017] Furthermore, the trimming board is detachably connected to the box body, and the bottom of the board body is provided with a detachable bottom cover.

[0018] After trimming, the roots will accumulate inside the board, and the blades will also wear down after a long period of use. By making the trimming board and the box detachable and installing a detachable bottom cover at the bottom of the trimming board, it is easier to clean and repair the inside of the trimming board and the blades.

[0019] Furthermore, the bottom of the seedling cup is provided with an opening and closing component, which includes a hook and a base plate connected to the bottom of the seedling cup via a hinge. When the opening and closing component is open, the seedling cup has a through structure. When the opening and closing component is closed, the side of the base plate is in contact with the bottom of the seedling cup. The hook is fixedly connected to the lower surface of the base plate. The bottom of the seedling cup is provided with a first cavity and a second cavity that are symmetrically distributed. The inner walls of the first cavity and the second cavity are both connected to the upper surface of the base plate via springs. The frame is fixedly connected with a lever, which is used to actuate the hook and separate the base plate from the bottom of the seedling cup when the sprocket mechanism rotates.

[0020] The second transmission mechanism in this invention is an intermediate transmission mechanism that serves as a link between the upper and lower parts. As the seedling receiving cup rotates with the sprocket, it needs to transfer the Salvia miltiorrhiza transplanted seedlings into the seedling guide tube at the same time it reaches the top of the seedling guide tube. By designing the bottom of the seedling receiving cup as an opening and closing component and using a horizontal rod to complete the opening and closing, the transplanted seedlings are automatically placed when they are sent to the top of the seedling guide tube, ensuring that the transplanted seedlings are not upside down during placement. At the same time, the seedling receiving cup achieves automatic opening and closing only through a mechanical mechanism, without the need for complex electromechanical design, thus achieving the effect of simplified structure and reduced cost.

[0021] Furthermore, a second magnetic element is fixedly connected to the side of the base plate, and the bottom of the seedling cup is made of ferromagnetic material.

[0022] Relying on a spring to open and close the bottom of the seedling cup can lead to spring deformation and partial failure over time, preventing the bottom from closing completely. This can cause the transplanted seedling to fall out before reaching the top of the guide tube during transport. By making the bottom of the cup ferromagnetic and installing magnets on the side of the base plate, the bottom of the cup and the base plate can be tightly fitted when the cup does not need to be opened. During normal transfer, the bottom of the cup will not open, and the spring will not exert tension on the base plate for an extended period of time. This ensures the normal transport of the transplanted seedling while extending the lifespan of the spring.

[0023] Furthermore, the frame is fixedly connected to a handrail, which includes a connecting end and a hand-held end. The connecting end is fixedly connected to the frame, and the hand-held end is provided with an anti-slip area.

[0024] By installing handrails, operators can easily control the direction of the self-propelled transplanter as it moves.

[0025] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0026] (1) The self-propelled transplanter provided by the present invention adopts a sliding rail slider mechanism, a sprocket mechanism and a seedling guide tube as the main transmission components of the whole self-propelled transplanter. The transplanted Salvia miltiorrhiza seedlings are transmitted by the above three mechanisms and cooperate with the movement of the moving parts to realize the mechanized planting of transplanted seedlings. Compared with the existing large self-propelled transplanters, the structure is simpler, which facilitates transportation and transfer and reduces costs.

[0027] (2) The self-propelled transplanter provided by the present invention utilizes a root trimming mechanism to automatically trim the roots of the transplanted Salvia miltiorrhiza seedlings. When the transplanted seedling slides or rolls on the trimming plate, the fine roots enter the square holes and are trimmed under the action of the rotating blades. At the same time, by setting the trimming plate at an angle, the transplanted seedlings rely on their own gravity to complete the movement, without the need for an additional conveyor belt, thus achieving the purpose of simplifying the mechanism.

Detailed Implementation

[0038] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0040] Example 1

[0041] Please refer to Figures 1-3An embodiment of the present invention provides a self-propelled transplanter, comprising: a frame 1, a first conveying mechanism 2, a second conveying mechanism 3, a seedling guide tube 4, and a movable component 5 rotatably connected to the frame 1 via a first rotating shaft. The rotatable connection can be a bearing connection or a sprocket connection. The movable component 5 can be a common rubber tire or a track. Depending on actual needs, a counterweight frame can be fixedly connected to the movable component. By adding counterweights to the counterweight frame, the weight of the transplanter is increased, thereby improving stability. The frame can adopt an existing self-propelled vehicle-type transplanter structure or a self-developed vehicle frame structure. The frame can be made of metal or plastic. The first conveying mechanism 2 includes a slider 201 and a slide rail 202 slidably connected together. The slide rail 202 is fixedly connected to the frame 1. The fixed connection can be welded or threaded. The slider 201 can slide along the slide rail 202 under the drive of a motor. The slider 201 and the slide rail 202 can slide based on a gear and rack mechanism or a rotary guide rail. A seedling cup 203 is fixedly connected to the slider 201. The second conveying mechanism 3 uses a vertically placed sprocket mechanism as the conveying component, specifically as follows: Figure 3 The sprocket mechanism shown consists of two rotating wheels 311 and a chain 310. A seedling receiving cup 302 is fixedly connected to the chain 310. The sprocket mechanism is rotatably connected to the frame 1 and driven by a motor, which can be a servo motor, stepper motor, or three-phase asynchronous motor. The seedling guide tube 4 is used to guide the *Salvia miltiorrhiza* seedlings transferred by the first conveying mechanism 2 and the second conveying mechanism 3 into the planting field. The seedling guide tube 4 is fixedly connected to the frame 1 and has a funnel-shaped top. Preferably, the openings of the seedling receiving cup 302 and the seedling delivery cup 203 are funnel-shaped, facilitating the transfer of *Salvia miltiorrhiza* transplanted seedlings while preventing the seedlings from being inverted and affecting planting. The first conveying mechanism 2, the second conveying mechanism 3, and the seedling guide tube 4... The seedling receiving cups are arranged vertically from top to bottom. When the receiving cup 302 moves with the chain to below the delivery cup 203, the opening of the receiving cup 302 faces vertically upward to ensure that the receiving cup 302 can normally receive the Salvia miltiorrhiza transplanted seedlings delivered by the delivery cup 203. There are two of each of the second conveying mechanism 3 and the slider 201, which are symmetrically distributed in the horizontal direction. The number of receiving cups 302 is several and evenly arranged. By setting two sliders in both the second and first conveying mechanisms, the effect of parallel planting along two paths is achieved. At the same time, the purpose of having several receiving cups evenly arranged is to ensure that the transplanted seedlings can be evenly and equally spaced as the second conveying mechanism rotates, so as to facilitate the subsequent management and operation of the crop.

[0042] Salvia miltiorrhiza transplanted seedlings can be fed into the seedling guide tube 4 by rotating a sprocket and tilting the seedling receiving cup 302. Preferably, an opening and closing component 7 can be installed at the bottom of the seedling receiving cup 302. The seedling delivery is accomplished by opening and closing the component 7. The main body of the opening and closing component 7 is a base plate 701 located at the bottom of the seedling receiving cup 302. The base plate 701 is hinged to the bottom of the seedling receiving cup 302. When the opening and closing component 7 is open, the seedling receiving cup 302 becomes a funnel-shaped structure with a through-hole structure, thus sending the Salvia miltiorrhiza transplanted seedlings into the seedling guide tube. When the opening and closing component 7 is closed, the side of the base plate 701 is in contact with the bottom of the seedling receiving cup 302, forming a cup with an open mouth but a closed bottom. The structure is used for transporting transplanted Salvia miltiorrhiza seedlings. The opening and closing component 7 includes a bottom plate 701 with a hook 702 fixedly connected to its lower surface. The fixed connection can be welding or bonding. The bottom of the seedling cup 302 has a first cavity 710 and a second cavity 711 symmetrically distributed. The inner walls of the first cavity 710 and the second cavity 711 are both connected to the upper surface of the bottom plate 701 by springs, which can be metal springs or plastic springs. A lever is fixedly connected to the frame 1. The lever is used to actuate the hook 702 and separate the bottom plate 701 from the bottom of the seedling cup 302 when the sprocket mechanism 3 rotates. The lever is parallel to the frame 1 and is not parallel to the bottom of the seedling cup 302. One end of the connection is located near the highest point of the sprocket mechanism's rotating wheel 311 in the vertical direction. When the seedling cup 302 moves to the actuating rod, the hook 702 is actuated, the spring is stretched, the bottom plate 701 opens, and the Salvia miltiorrhiza transplanted seedlings in the seedling cup 302 fall into the seedling guide tube 4. The seedling cup 302 continues to move, the actuating rod disengages from the hook, the spring contracts, and the bottom plate 701 closes. To ensure that the actuating rod can disengage from the hook 702 normally after being actuated, the hook 702 is triangular or rod-shaped. By designing the bottom of the seedling cup as an opening and closing component and using a horizontal actuating rod to complete the opening and closing, the transplanted seedlings are automatically placed when they are sent above the seedling guide tube, ensuring that the transplanted seedlings do not have a beginning and an end during placement. In the inverted state, the seedling cup automatically opens and closes via a mechanical mechanism, eliminating the need for complex electromechanical design and achieving a simplified structure and reduced costs. As a preferred embodiment, a second magnetic element is fixedly connected to the side of the base plate 701. The bottom of the seedling cup is made of ferromagnetic material, and the second magnetic element can be a permanent magnet or an electromagnet. The ferromagnetic material can be iron, steel, nickel, or cobalt. By making the bottom of the cup ferromagnetic and providing magnets on the side of the base plate, it is ensured that the bottom of the cup and the base plate can fit tightly together when the seedling cup does not need to be opened. During normal transfer, the bottom of the cup will not open, and the spring will not exert tension on the base plate for extended periods, ensuring normal transport of the transplanted seedlings while extending the lifespan of the spring.

[0043] When the self-propelled transplanter is working, the first conveying mechanism 2 feeds in the Salvia miltiorrhiza seedlings. The feeding can be done manually or by using an existing planting machine with a seedling storage box and conveyor belt. The initial root cutting of the Salvia miltiorrhiza seedlings can be done manually or by using an automatic cutting device on the existing planting machine. The Salvia miltiorrhiza seedlings enter the receiving cup 302 in the second conveying mechanism 3 through the seedling feeding cup 203. Then, as the sprocket of the second conveying mechanism 3 moves, it drives the receiving cup 302 to move. When the receiving cup with the Salvia miltiorrhiza seedlings reaches directly above the seedling guide tube 4, the opening and closing component 7 at the bottom of the receiving cup opens, and the Salvia miltiorrhiza root segment enters into the seedling guide tube 4. The Salvia miltiorrhiza seedlings are then transported to the planting field through the seedling guide tube 4.

[0044] The self-propelled transplanter is also equipped with a handrail 8. One end of the handrail 8 is fixedly connected to the frame 1. The fixed connection can be welded or threaded. The other end of the handrail 8 is for the operator to hold, so that the operator can control the direction of the self-propelled transplanter when it is moving to plant or transport.

[0045] Example 2

[0046] Please refer to Figures 4-7This invention provides a self-propelled transplanter based on Embodiment 1. The self-propelled pruning machine further includes a root pruning mechanism 6. The main functional component of the root pruning mechanism 6 is a pruning plate 601 built into and connected to the inner wall of a housing 602. The pruning plate 601 is entirely made of a metal or plastic plate of a certain thickness. The pruning plate is hollow and contains a roller 611. The plate body 610 of the pruning plate 601 is inclined downwards in the vertical direction, and a number of square holes 612 are opened on the surface of the plate body 610. The roller 611 is rotatably connected to the cavity of the plate body, and the roller 611 is driven by a motor. The surface of roller 611 is provided with blades 613. Several blades 613 are evenly distributed around the axis of roller 611 to form a blade group. The blades 613 can be metal or plastic. For root crops like Salvia miltiorrhiza, pruning some roots before transplanting can promote root regeneration and taproot development. Newly regenerated roots can more effectively absorb water and nutrients from the soil. At the same time, appropriate root pruning can reduce the short-term water and nutrient requirements of the plant after transplanting, thereby improving its survival rate. The root pruning mechanism 6 automatically prunes the roots of the transplanted Salvia miltiorrhiza seedlings. When the seedling slides on the pruning plate 601, the fine roots enter the square holes 61. In step 2, pruning is achieved under the action of rotating blades. Typically, for transplanted Salvia miltiorrhiza seedlings, only a 2-3cm root segment is retained. By setting the side length of the square hole 612 to less than 2cm, the root segment is prevented from falling directly into the square hole 612 during the sliding process on the pruning plate, thus preventing damage to the Salvia miltiorrhiza seedling. The number of blade sets is several and evenly distributed along the axial direction of the roller 611. Setting multiple evenly distributed blade sets makes pruning more uniform. The pruning plate 601 is inclined, allowing the transplanted seedlings to move solely by their own weight, eliminating the need for an additional conveyor belt and simplifying the mechanism. As a preferred embodiment, the square hole 612 is provided with... A sloping anti-stopping block 614 is fixedly connected to the square hole 612 along the lower edge of the inclined plate. The fixed connection can be welding or bonding. The anti-stopping block 614 can also be integrally formed with the plate 601 during manufacturing. The edge of the square hole 612 has a certain thickness. The lower edge of the square hole 612 on the inclined trimming plate 601 is set as a slope to prevent the roots of the transplanted seedling from getting stuck on the edge of the square hole when it slides. The root trimming mechanism 6 can be set above the first conveying mechanism 2, between the first conveying mechanism 2 and the second conveying mechanism 3, or between the second conveying mechanism 3 and the seedling guide tube.

[0047] The trimming board 601 is detachably connected to the housing 602, and the bottom of the board 610 is provided with a detachable bottom cover. After long-term use, a large number of trimmed roots will remain inside the trimming board and the blades will wear down. By making the trimming board and the housing detachable and providing a detachable bottom cover at the bottom of the trimming board, it is convenient to clean and repair the inside of the trimming board and the blades.

[0048] As a preferred embodiment, the trimming plate 601 may be provided with stepped baffles from left to right along the inclined direction of the plate body 610. The baffles can rotate along the inclined direction of the plate body 610 under the drive of a motor. The rotation speed of the baffles is adjustable. Through the baffles, the downward sliding speed of the Salvia miltiorrhiza transplanted seedlings on the trimming plate can be controlled, thereby improving the trimming effect. At the same time, the stepped baffle arrangement can ensure that when several Salvia miltiorrhiza transplanted seedlings are placed on the trimming plate at the same time, they can be transported away in an orderly manner and enter the subsequent conveyor, so as not to cause multiple Salvia miltiorrhiza seedlings to pile up and affect subsequent operations.

[0049] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0050] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
