Description

Technical Field

[0001] This utility model relates to the technical field of Codonopsis pilosula cultivation, and in particular to an adjustable automatic seeder for Codonopsis pilosula cultivation. Background Technology

[0002] Codonopsis pilosula is an important traditional Chinese medicine with the effects of strengthening the body, relieving fatigue, and improving dry mouth and thirst. It is often used to treat physical weakness, post-illness recovery, and loss of appetite.

[0003] With the large-scale and intensive development of Codonopsis pilosula cultivation, promoting mechanized cultivation has become a new requirement for the industry. Currently, mature machinery is available for plowing, ridging, and ditching in Codonopsis pilosula cultivation. However, the sowing process mainly relies on manual labor to follow the machines in arranging the plants. Traditional manual sowing cannot guarantee consistent plant spacing, and at least two people are needed for sowing over a wide area. This method is inefficient, labor-intensive, and requires a large workforce, making it difficult to meet the future requirements of mechanized harvesting of Codonopsis pilosula.

[0004] Existing technology, such as patent publication number CN215735755U, discloses a semi-automatic precision seeder for Codonopsis pilosula, specifically relating to the technical field of agricultural production machinery. It includes a frame, a servo motor mounted on the frame, and a lithium battery electrically connected to the servo motor. The frame is rotatably connected to traveling wheels and drive wheels. A drive shaft is located between two drive wheels, and a driven gear is mounted on the drive shaft. The servo motor is covered with a driving gear and a first transmission gear. A support is also provided on the frame, and a rotating shaft is rotatably connected to the support. A second transmission gear is mounted on the rotating shaft, and a transmission chain connects the second transmission gear and the first transmission gear. A first roller is mounted on the rotating shaft, and a second roller is rotatably connected to the frame. A transmission belt is tensioned between the second roller and the first roller, and seed protection plates are distributed on the transmission belt.

[0005] While the aforementioned existing patent literature has solved the problems of low efficiency and poor uniformity of artificial sowing of Codonopsis pilosula to some extent, it is still inefficient for one person to sow Codonopsis pilosula over a wide area, requiring at least two people. Moreover, the planting spacing of Codonopsis pilosula is generally 5-10 cm, and the spacing of the seed protection plates distributed on the transmission belt cannot be adjusted, making it impossible to adjust the spacing according to the land to be sown, so as to achieve the optimal spacing for sowing in different soil environments.

[0028] Example 1

[0029] Reference Figures 1-5 This utility model discloses an adjustable automatic seeder for planting Codonopsis pilosula, including a movable frame 1, and a variable-pitch gripping mechanism, including a horizontal plate 2 and multiple grippers 3 arranged along the length of the horizontal plate 2. The multiple grippers 3 are connected by variable-pitch components 4 installed on the horizontal plate 2. The movable mechanism includes a transverse movement mechanism 5 installed on one side of the top of the movable frame 1. A longitudinal movement mechanism 6 is installed on the transverse movement mechanism 5. The longitudinal movement mechanism 6 includes a mounting plate 601. The horizontal plate 2 is fixedly installed on the mounting plate 601. The arrangement mechanism includes a support frame 7. The support frame 7 has the same number of guide plates 8 as the grippers 3 inside.

[0030] With the above structure and the setting of the guide plate 8, it is convenient for one worker to lay out the Codonopsis pilosula to be planted. Then, the clamping device 3 can be switched back and forth between the guide plate 8 and the sowing position through the horizontal movement mechanism 5 and the vertical movement mechanism 6. During the process of moving the Codonopsis pilosula held by the clamping device 3 to the sowing position, the spacing of the Codonopsis pilosula plants held by the multiple clamping devices 3 can be adjusted according to the spacing of the Codonopsis pilosula plants through the spacing variable device 4, so as to achieve the optimal spacing for sowing for different soil environments.

[0031] Reference Figure 2In detail, in this embodiment, the pitch-changing component 4 includes fixing blocks 401 fixed at both ends of the horizontal plate 2, a guide post 402 connected between the two fixing blocks 401, a plurality of clamping fixing plates 403 sleeved on the outside of the guide post 402, one side wall of the middle clamping fixing plate 403 fixed on the horizontal plate 2, and the other clamping fixing plates 403 away from the horizontal plate 2. A clamp 3 is installed at the bottom end of each clamping fixing plate 403, and the plurality of clamping fixing plates 403 are connected by a scissor bracket 404. A first cylinder 405 is fixed on the horizontal plate 2, and the telescopic end of the first cylinder 405 is connected to one of the other clamping fixing plates 403. The scissor frame 404 adopts an existing structure, which consists of multiple pins and linkage rods. Fixed pins are provided on the side walls of multiple clamping plates 403. The linkage rods are rotatably connected between adjacent clamping plates 403. When one clamping plate 403 moves, the other clamping plates 403 can be moved synchronously through the scissor frame 404, so as to realize the adjustment of the distance between the ginseng held by the clamps 3 on the two adjacent clamping plates 403.

[0032] Reference Figure 3 In detail, in this embodiment, the clamp 3 includes an electromagnetic telescopic rod 301 fixed to the bottom of the clamping plate 403. A first connecting ear 302 is fixed to the bottom of the electromagnetic telescopic rod 301, and a second connecting ear 303 is fixed to the telescopic end of the electromagnetic telescopic rod 301. The first connecting ear 302 is connected to a clamping arm 304, and the second connecting ear 303 is rotatably connected to the middle of the clamping arm 304 via a connecting rod 305. The bottom end of the clamping arm 304 is fixed to the clamping plate 306. The electromagnetic telescopic rod 301 uses existing products, and its working principle is based on the interaction of electromagnetic induction and electromagnetic force. When energized, the electromagnetic coil generates a magnetic field, which interacts with the magnetic material inside the telescopic rod, thereby generating a pushing or pulling force, causing the telescopic rod to telescopically extend or retract. By controlling the magnitude and direction of the current, the movement state and speed of the telescopic rod can be precisely controlled. When the telescopic end of the electromagnetic telescopic rod 301 extends or retracts, it will cause the clamping plates 306 at the bottom of the clamping arm 304 to move closer or further apart, so as to clamp and release the Codonopsis pilosula.

[0033] A splitter 9 is fixed on the horizontal plate 2. Multiple electromagnetic telescopic rods 301 are connected to the output end of the splitter 9 via wires 10. The input end of the splitter 9 is connected to an external controller (not shown in the figure). The splitter 9 is an existing product. The direction of the current is controlled by the external controller, and the extension and retraction control of the electromagnetic telescopic rods 301 of the multiple clamps 3 is realized through the wires 10.

[0034] In detail, in this embodiment, a seat plate 14 is fixed to the side of the top of the mobile frame 1 away from the first support plate 501. The height of the seat plate 14 is lower than the height of the top of the guide plate 8. When the worker sits on the seat plate 14, the ginseng can be laid out, making it convenient for the clamp 3 to adjust the spacing of the ginseng before sowing.

[0035] Example 2

[0036] Reference Figure 1 and Figure 4 Based on the same concept as in Embodiment 1, this adjustable automatic seeder for planting Codonopsis pilosula also includes a first support plate 501 fixed to one side of the top of the movable frame 1. The transverse movement mechanism 5 includes a slide rail 502 fixed to the first support plate 501, a first slider 503 slidably connected to the slide rail 502, a vertical plate 504 fixed to the first slider 503, and a second cylinder 505 fixed to the top of the support plate. The telescopic end of the second cylinder 505 is connected to one side wall of the first slider 503. The longitudinal movement mechanism 6 includes a linear module 602 vertically fixed to one side wall of the vertical plate 504. The linear module 602 includes a second slider 603, and the top of the mounting plate 601 is fixed to the second slider 603. By controlling the second cylinder 505, the longitudinal movement mechanism 6 set on the first slider 503 can be driven to move laterally. The linear module 602 can control the mounting plate 601 installed on the second slider 603 to move longitudinally, so as to realize the switching of the clamp 3 between the guide plate 8 and the sowing position. The linear module 602 can adopt the existing screw and nut structure. Of course, the transverse movement mechanism 5 and the longitudinal movement mechanism 6 are not limited to the above methods.

[0037] Example 3

[0038] Reference Figure 1 and Figure 4 Based on the same concept as in Embodiment 2 above, this adjustable automatic planter for Codonopsis pilosula also includes an arrangement mechanism comprising a second support plate 11 fixed to the other side of the top of the mobile frame 1. A sowing space is left between the first support plate 501 and the second support plate 11. The side wall of the support frame 7 is fixed to the second support plate 11 by a vertical rod 12. The guide plate 8 is inclinedly arranged inside the support frame 7. A connecting plate 13 is fixed between the bottoms of the multiple guide plates 8. The two ends of the connecting plate 13 are fixed to the support frame 7. A clamping space is left between the lower end of the guide plate 8 and the lower end of the support frame 7. Since the Codonopsis pilosula on the guide plate 8 is gripped by the variable-distance gripping mechanism and planted after adjusting the plant spacing, the width of the multiple guide plates 8 for placing the Codonopsis pilosula is narrower than the sowing area. Compared with the traditional method of two people sowing, this utility model only requires one person. The guide plate 8 is tilted so that after the staff puts the ginseng into the guide plate 8 from the high end, it moves to the bottom end of the guide plate 8 and is held by the clamp 3. This design can avoid the clamp 3 posing a threat to the staff.

[0039] It should be noted that the first cylinder 405, the electromagnetic telescopic rod 301, the second cylinder 505, and the linear module 602 are all existing products, and their principles will not be elaborated on here. The telescopic length of the telescopic ends of the first cylinder 405, the electromagnetic telescopic rod 301, the second cylinder 505, and the linear module 602 will be determined by technicians based on the actual situation.

[0040] Working principle:

[0041] The worker sits on seat board 14 and evenly arranges the ginseng to be sown on the upper end of guide plate 8. After one row is laid, the telescopic end of the first cylinder 405 is shortened. Through the guide column 402, clamping and fixing plate 403 and scissor frame 404, multiple clamps 3 are driven to move closer to each other. Then, the clamps 3 are moved to the clamping space by the horizontal movement mechanism 5 and the vertical movement mechanism 6. The electromagnetic telescopic rod 301 is controlled to clamp the laid row of ginseng. Then, the horizontal movement mechanism 5 and the vertical movement mechanism 6 are controlled to move the clamps 3 holding the ginseng to the sowing position below the sowing space. During this process, the telescopic end of the first cylinder 405 is extended a certain distance according to the plant spacing requirements. Then, the electromagnetic telescopic rod 301 is controlled to release the ginseng held by the clamps 3 above the sowing position to ensure the consistency of the plant spacing of each row of ginseng. After the clamps 3 have taken the ginseng from the guide plate 8, the worker can lay the next row of ginseng to be planted. After each row of Codonopsis pilosula is sown, the mobile frame 1 is moved forward a certain distance, and the above steps are repeated to sow the next row of Codonopsis pilosula.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
