Description

Technical Field

[0001] The present invention belongs to the technical field of breeding and transplanting, and specifically relates to a Chinese herbal medicine breeding and transplanting device. Background Art

[0002] In a Chinese herbal medicine experimental field, in order to screen high-quality seedlings and transplant the selected seedlings from the collective seedling field to the high-quality seedling field, a Chinese herbal medicine breeding and transplanting device is generally used for breeding and transplanting work to ensure the survival rate and growth efficiency of the seedlings.

[0003] The existing dryland Chinese herbal medicine automatic transplanting machine with the application number of CN202211040985.1 includes a mobile chassis, a seedling picking and separating mechanism, a seedling conveying mechanism, a transplanting mechanism and a power transmission mechanism. The seedling picking and separating mechanism clamps seedlings from the seedling tray and sends them to the seedling conveying mechanism; the transplanting mechanism receives seedlings from the seedling conveying mechanism, vertically implants the seedlings into the soil, and covers the soil and waters them. Among them, the seedling picking and separating mechanism clamps and sends seedlings through the long-stroke reciprocating sliding of the clamping pliers, and cooperates with the chain transmission mechanism to convey the seedling tray, realizing the functions of automatic, intermittent and efficient seedling separation, and maximizing the neatness of the horizontal row during transplantation, eliminating the occurrence of missing seedlings. Although the application of the above transplanting robot has expanded the applicable range of Chinese herbal medicine transplantation to a certain extent, its automation level still has obvious limitations. The existing transplanting robot can only complete the transplanting operation of seedlings, and the seedlings to be transplanted still need to be screened and placed in advance by manual or other equipment. This segmented operation mode results in the lack of continuity in the process of Chinese herbal medicine breeding and transplanting, and fails to achieve the full-process automation from seedling screening to transplantation, thus restricting the overall efficiency and applicable range of the equipment. Summary of the Invention

[0004] To solve the problem that the existing transplanting robot fails to achieve the full-process automation from seedling screening to transplantation mentioned in the above background art, the present invention provides a Chinese herbal medicine breeding and transplanting device.

[0009] The positioning and lifting member includes a spiral sleeve, a spiral groove is formed on the outer wall of the spiral sleeve, and a lifting rod is slidably sleeved on the inner wall of the spiral sleeve.

[0010] Preferably, a servo motor is fixedly connected to the inner cavity of the bottom of the carriage, an output end of the servo motor is fixedly connected to the spiral sleeve, a ring block is sleeved on the outer wall of the spiral sleeve, a hemispherical block is fixedly connected to the inner side of the ring block, and an outer wall of the hemispherical block is slidably connected in the spiral groove of the spiral sleeve.

[0011] Preferably, the ring block is slidably connected to a chute plate through a slide bar, the top of the chute plate is fixedly connected to the bottom of the carriage, a limiting plate is fixedly connected to the bottom of the ring block, a side wall of the limiting plate is slidably attached to the outer wall of the spiral sleeve, a square block is fixedly connected to the lower end of the limiting plate, the top of the square block is fixedly connected to the bottom of the lifting rod, and an annular groove is formed at the lower end of the spiral sleeve.

[0012] Preferably, the earth-shoveling member includes a first rotating shaft and a second rotating shaft;

[0013] One end of the second rotating shaft is slidably connected in the annular groove, the other end of the second rotating shaft is fixedly connected to the lower end of the chute plate, and the first rotating shaft is fixedly connected to the side wall of the square block.

[0014] Preferably, a pair of second connecting rods are rotatably connected to the middle of the second rotating shaft, and a pair of first connecting rods are rotatably connected to the outer wall of the first rotating shaft in a cross-symmetrical manner.

[0015] Preferably, the upper ends of the first connecting rods are symmetrically rotatably connected to the second connecting rods, and arc-shaped supporting plates are symmetrically fixedly connected to the lower ends of the first connecting rods on both sides.

[0016] Preferably, the earth-pushing mechanism includes a rotating plate rotatably connected to the arc-shaped supporting plate, a telescopic column is rotatably connected to the side wall of the rotating plate, and the outer wall of the telescopic column movably penetrates through the inner cavity of the arc-shaped supporting plate.

[0017] Preferably, an arc-shaped pressing plate is rotatably connected to one end of the telescopic column away from the rotating plate, and the arc curvature of the arc-shaped pressing plate is consistent with the arc curvature of the arc-shaped supporting plate.

[0018] Preferably, a return spring is movably sleeved on the outer wall of the telescopic column, and two ends of the return spring respectively abut against the outer wall of the arc-shaped pressing plate and the inner cavity of the arc-shaped supporting plate.

[0019] Preferably, an observation head for screening medicinal materials is fixedly connected to the upper side wall of the carriage.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The present invention realizes the integrated operation of automated screening and transplanting of Chinese medicinal material seedlings by setting up a transplanting mechanism and a bulldozer mechanism in cooperation with an observation head to screen Chinese medicinal materials. First, the Chinese medicinal materials are intelligently screened by the observation head, and then the selected Chinese medicinal materials together with the original soil with their roots are dug out intact by the transplanting mechanism, and are accurately placed in a high-quality seedling field for centralized cultivation by the bulldozer mechanism. The seedling screening, digging and transplanting processes are integrated into a continuous automated process, overcoming the limitations of traditional transplanting robots that have a single function and can only perform transplanting operations, effectively solving the technical bottleneck of seedling pre-screening and positioning relying on manual labor or other equipment, and improving the application scope of the device.

[0022] The present invention improves the movement stability of the device by arranging the coordination of structures such as the spiral sleeve, the hemispherical block and the ring block. Under the limitation of the limit plate and the slide groove plate, the spiral sleeve rotates to squeeze the hemispherical block, which can push the ring block to move axially, thereby eliminating the radial deviation of the lifting rod. The lifting rod can ensure that the first rotating shaft moves downward stably in a horizontal state, and the annular groove can ensure the stable positioning of the second rotating shaft, thereby providing a stable foundation for the next step of shoveling.

[0023] The present invention improves the survival rate of Chinese medicinal materials after transplantation by arranging the coordination of structures such as the arc support plate, the first connecting rod and the second connecting rod. The arc support plate is changed from an expanded state to a combined state by the linkage of the first connecting rod, and the roots of the Chinese medicinal materials and the original soil are shoveled up together to dig out the selected Chinese medicinal materials. After transplantation, since the original soil exists at the root system of the Chinese medicinal materials, the adaptability of the Chinese medicinal materials to the new soil environment can be improved, thereby increasing their survival rate.

[0024] The present invention improves the efficiency of transplanting by arranging the cooperation of structures such as the rotating plate and the curved surface extrusion plate. The curved surface extrusion plate can be pressed downward by the weight of the Chinese medicinal material plants and the original soil, and then the rotating plate is pushed out to form a certain angle with the curved surface supporting plate. During transplanting, the soil of the high-quality seedling field is pushed toward both sides by the rotating plate, effectively avoiding the slipping of the curved surface supporting plate surface. By filling the original soil, there is no need for the soil-returning process, thereby improving the transplanting efficiency of the Chinese medicinal materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 to 11 shown, the present invention provides a Chinese medicinal material breeding and transplanting device, including a moving frame 1, a mounting plate 2 is fixedly connected above the side wall of the moving frame 1, a stepping motor group 3 is slidably mounted on the top of the moving frame 1, the bottom of the stepping motor group 3 is fixedly connected with a sliding frame 5, and further includes:

[0040] The transplanting mechanism 6 is located at the bottom of the carriage 5;

[0041] The earth-pushing mechanism 7 is arranged symmetrically on both sides of the transplanting mechanism 6;

[0042] Among them, the transplanting mechanism 6 includes a positioning and lifting member 61 and an earth-shoveling member 62;

[0043] The positioning and lifting member 61 includes a spiral sleeve 612. The outer wall of the spiral sleeve 612 is provided with a spiral groove, and a lifting rod 618 is slidably sleeved on the inner wall of the spiral sleeve 612. An observation head 4 for screening medicinal materials is fixedly connected to the upper side wall of the carriage 5.

[0044] Adopting the above scheme: The length and width dimensions of the moving frame 1 can be adaptively adjusted according to the actual size of the experimental field. The height of the moving frame 1 is controlled by an electric telescopic plate to ensure that the arc-shaped supporting plate 622 contacts the ground in the unfolded state to excavate Chinese medicinal materials, and to ensure that the arc-shaped supporting plate 622 is away from the bottom surface in the closed state for easy transportation. A pair of universal wheels for walking in the experimental field are symmetrically and fixedly connected to the bottom of the moving frame 1. The stepping motor group 3 is mainly composed of a stepping motor, a gear, a rack, and a slide rail provided on the moving frame 1, and is used to drive the carriage 5 to slide axially back and forth on the moving frame 1. The moving frame 1 is fixedly connected to the walking module of the transplanting robot through the mounting plate 2. The transplanting robot also includes an intelligent control module and a support mounting module. The stepping motor and the servo motor 611 are both electrically connected to the intelligent control module, and the stepping motor and the servo motor 611 are both equipped with a reverser to facilitate the reverse rotation of the rotating shaft.

[0045] As Figure 4 and Figure 5 shown, a servo motor 611 is fixedly connected to the inner cavity of the bottom of the carriage 5. The output end of the servo motor 611 is fixedly connected to a spiral sleeve 612. An annular block 615 is sleeved on the outer wall of the spiral sleeve 612. A hemispherical block 617 is fixedly connected to the inner side of the annular block 615. The outer wall of the hemispherical block 617 is slidably connected to the spiral groove of the spiral sleeve 612.

[0046] As Figures 5 to 7 shown, the annular block 615 is slidably connected to a chute plate 616 through a slide rod. The top of the chute plate 616 is fixedly connected to the bottom of the carriage 5. A limiting plate 614 is fixedly connected to the bottom of the annular block 615. The side wall of the limiting plate 614 is slidably attached to the outer wall of the spiral sleeve 612. A square block 613 is fixedly connected to the lower end of the limiting plate 614. The top of the square block 613 is fixedly connected to the bottom of the lifting rod 618. An annular groove 619 is opened at the lower end of the spiral sleeve 612.

[0047] By adopting the above scheme, under the limiting action of the slide plate 616, the ring block 615 and the limiting plate 614, when the spiral sleeve 612 rotates, the lifting rod 618 on the inner wall can be pushed stably, and only axial movement occurs without rotation, thereby effectively eliminating radial deviation and improving movement stability.

[0048] like Figure 7 As shown, the shovel member 62 includes a first rotating shaft 624 and a second rotating shaft 625;

[0049] One end of the second rotating shaft 625 is slidably connected to the annular groove 619 , the other end of the second rotating shaft 625 is fixed to the lower end of the sliding groove plate 616 , and the first rotating shaft 624 is fixed to the side wall of the block 613 .

[0050] like Figure 7 and Figure 8 As shown, a pair of second connecting rods 623 are rotatably connected to the middle part of the second rotating shaft 625, and a pair of first connecting rods 621 are rotatably connected to the outer wall of the first rotating shaft 624 in a cross-symmetrical manner; the upper end of the first connecting rod 621 is symmetrically rotationally connected to the second connecting rod 623 on both sides, and the lower end of the first connecting rod 621 is symmetrically fixed with arc support plates 622 on both sides.

[0051] The above scheme is adopted: the length of the spiral sleeve 612 and the size of the arc support plate 622 can be adapted and adjusted according to the actual category of Chinese medicinal materials, the side of a pair of arc support plates 622 close to each other is set as a fitting plane, the bottom edge of the arc support plate 622 is set as an inclined surface for cutting soil, and the first connecting rod 621 is located on one side of the arc support plate 622, which is used to drive the arc support plate 622 to rotate and dig out the Chinese medicinal materials without causing the Chinese medicinal materials plants to shift and fall.

[0052] like Figures 8 to 11 As shown, the bulldozer mechanism 7 includes a rotating plate 71 rotatably connected to the arc-surface support plate 622, and the side wall of the rotating plate 71 is rotatably connected to a telescopic column 74, and the outer wall of the telescopic column 74 movably penetrates the inner cavity of the arc-surface support plate 622; the end of the telescopic column 74 away from the rotating plate 71 is rotatably connected to a curved extrusion plate 72, and the curvature of the curved surface of the curved extrusion plate 72 is consistent with the curvature of the curved surface of the curved support plate 622; the outer wall of the telescopic column 74 is movably sleeved with a return spring 73, and the two ends of the return spring 73 respectively abut against the outer wall of the curved extrusion plate 72 and the inner cavity of the curved support plate 622.

[0053] The above scheme is adopted: the edges of a pair of rotating plates 71 are provided with beveled edges for easy shoveling of soil. The soil of the high-quality seedling field is pushed to both sides by the rotating plates 71 that have been pushed out at a certain angle, effectively avoiding the slipping of the surface of the arc support plate 622. The rotating plates 71 cooperate with the arc support plate 622 to push the new soil to both sides while putting the Chinese medicinal materials and the original soil into the pit. These two steps are carried out simultaneously, reducing the operation of returning the soil and simplifying the transplanting process.

[0054] Working principle and usage process of the present invention:

[0055] First, the walking module of the transplanting robot drives the moving frame 1 to move in the test field. At the same time, the stepping motor group 3 can drive the sliding frame 5 to move axially back and forth through the stepping motor. The observation head 4 located above the sliding frame 5 continuously detects and screens Chinese medicinal materials with good growth. Whenever a Chinese medicinal material is selected, the operation of the stepping motor group 3 is stopped, so that the sliding frame 5 is located on the side of the Chinese medicinal material plant. Then, the servo motor 611 is started to drive the spiral sleeve 612 to rotate. The hemispherical block 617 is extruded through the spiral groove opened on the outer wall of the spiral sleeve 612. The hemispherical block 617 drives the ring block 615 to move downward. At the same time, the ring block 615 also presses down the limiting plate 614, thereby driving the square block 613 to move downward. When the square block 613 moves downward, it can drive the lifting rod 618 and the first rotating shaft 624 to move downward synchronously. The lifting rod 618 slides and is limited in the spiral sleeve 612, so that the first rotating shaft 624 can move downward stably in the horizontal state. And when the spiral sleeve 612 rotates, the ring block 615 is also slidably connected to the chute plate 616 through the slide rod, so that the chute plate 616 and the spiral sleeve 612 always maintain a parallel state. Therefore, the second rotating shaft 625 connected to the bottom of the chute plate 616 is stably slidably connected to the annular groove 619, to keep the abutting and limiting of the spiral sleeve 612, thereby improving the stability of the device;

[0056] Secondly, the arc-shaped support plate 622 is in the Figure 8 deployed state when the moving frame 1 is walking. Since the ring block 615 is fixedly connected to the bottom of the chute plate 616 and is limited by the annular groove 619, the position of the upper end of the second link 623 rotatably connected to the second rotating shaft 625 does not move up and down. The electric telescopic rod lowers the height of the moving frame 1, and the edge of the arc-shaped support plate 622 is in contact with the bottom soil. When the first rotating shaft 624 moves downward, the intersection of a pair of first links 621 can be moved downward synchronously. Since the lower end of the second link 623 is rotatably connected to the upper end of the first link 621, the first link 621 can be pulled to rotate. The arc-shaped support plate 622 located at the lower end of the first link 621 rotates synchronously. A pair of arc-shaped support plates 622 change from the deployed state to the Figure 10 merged state. During the merging process, the roots and the original soil of the Chinese medicinal materials are shoveled up together, and the selected Chinese medicinal materials are dug out. Digging out together with the original soil can improve the survival rate of the Chinese medicinal materials after transplantation;

[0057] Next, when the Chinese medicinal material plants and the original soil are located in the middle of a pair of arc-surface supporting plates 622, the weight generated can press the arc-surface extrusion plate 72 downward, pushing the telescopic column 74 while compressing the reset spring 73. The telescopic column 74 moves toward the outside of the arc-surface supporting plate 622 to push the rotating plate 71 to rotate, so that the rotating plate 71 and the arc-surface supporting plate 622 form a certain angle. At this time, the mobile frame 1 moves the Chinese medicinal materials to the designated position of the high-quality seedling field through the universal wheels and the stepper motor group 3. During the movement, the mobile frame 1 is raised in height through the electric telescopic rod to ensure that the arc-surface supporting plate 622 does not contact the ground. After reaching the designated position, the mobile frame 1 lowers its height to make the rotating plate 71 contact the ground, and then starts the servo motor 611. Reverse rotation: The reverse operation is similar to the above operation, so that the block 613 moves upward. Under the push of the second connecting rod 623, the first connecting rod 621 rotates in the opposite direction, so that the arc support plate 622 changes from the combined state to the expanded state. In this process, the soil of the high-quality seedling field is pushed to both sides by the rotating plate 71 that has been pushed out to a certain angle, which effectively avoids the surface slipping of the arc support plate 622. The rotating plate 71 cooperates with the arc support plate 622 to push the new soil to both sides while putting the Chinese medicinal materials and the original soil into the pit, so that the newly dug pit can adapt to the roots of the Chinese medicinal materials and the original soil. Then, the arc extrusion plate 72 and the rotating plate 71 are reset by the pulling force of the reset spring 73 to complete the transplanting.

[0058] Finally, the Chinese medicinal materials are screened through the observation head 4, and then the selected Chinese medicinal materials together with the original soil of the root system are dug out completely by the transplanting mechanism 6, and are accurately placed in a high-quality seedling field for centralized cultivation by the bulldozer mechanism 7, integrating the seedling screening, digging and transplanting processes into a continuous automated process, thereby improving the application scope of the device.
