Description

Technical Field

[0001] The present invention relates to the technical field of Pulsatilla chinensis transplanting technology, and in particular to asexual propagation and transplanting device for Pulsatilla chinensis in cold regions. Background Art

[0002] Pulsatilla chinensis is a perennial herb of the Ranunculaceae family, with dual functions of medicine and ornament. It has the effects of clearing heat and detoxifying, stopping dysentery, and drying dampness. It is a commonly used traditional Chinese medicine in clinical practice. However, the ecological distribution of Pulsatilla chinensis is extremely limited, the plant resources are limited, and most of them are in the wild state. The amount of artificial sowing and cultivation is extremely small, far from meeting the current market demand. The cold-region black soil economy is a modern economic type proposed based on the cold-region black soil resources. In order to actively promote the development of the Chinese medicine industry in the northernmost cold regions of China and broaden the utilization of Pulsatilla chinensis resources, measures for asexual propagation and transplanting of Pulsatilla chinensis in cold regions will be introduced.

[0003] Currently, for the asexual propagation and transplanting of Pulsatilla chinensis, usually, the Pulsatilla chinensis plants are first divided, and a small amount of soil should be attached to the roots of each plant to ensure its survival. Then, the divided Pulsatilla chinensis seedlings are planted in the cold-region soil. Most of the existing plant transplanting devices assist workers in transplanting plants by automatically digging pits. After digging the pits, workers still need to frequently squat and stand up to insert the plants into the pits. It is inconvenient to automatically adjust the digging and transplanting spacing of the transplanting device according to the transplanting requirements, resulting in a high labor intensity and reduced transplanting efficiency for workers. Moreover, if the plants need to be transplanted to sloping land, the transplanting device driven by conventional wheels is prone to problems of inconvenient movement due to the terrain.

[0004] Currently, there is no good method on the market to solve the above problems. Summary of the Invention

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0031] As described above, when the existing transplanting device digs pits in the soil, it is inconvenient to sequentially insert the transplanted plants into the pits and inconvenient to adjust the transplanting spacing of the plants according to the transplanting requirements. The movement of the transplanting device driven by conventional wheels is not suitable for sloping terrains, which affects the smoothness of the device movement.

[0032] In view of this, the present invention provides a cold-region Pulsatilla chinensis asexual propagation transplanting device, which can adjust the horizontal spacing between digging pits and plant transplantation through a spacing adjustment mechanism to meet different transplanting requirements of cold-region Pulsatilla chinensis. The seedling feeding mechanism can transport the transplanted Pulsatilla chinensis plants to the seedling inserting mechanism for temporary storage. The lifting mechanism can drive the digging mechanism and the seedling inserting mechanism to reciprocate up and down. Operating the seedling inserting mechanism can drop the temporarily stored Pulsatilla chinensis plants into the pits, avoiding the high labor intensity of staff frequently squatting and standing for seedling insertion. This device is equipped with a moving mechanism to enable the device to move smoothly on sloping terrains.

[0033] The following Figures 1 to 9 Specifically describe the present invention.

[0034] As Figures 1 to 9As shown in the figure, the present invention provides a transplanting device, especially a transplanting device for asexual propagation of Pulsatilla chinensis in cold regions. In this embodiment, the transplanting device includes a fixed frame 1. A lifting mechanism 2 extending to the middle of the fixed frame 1 is fixedly connected to the top wall of the fixed frame 1. One end of the bottom of the lifting mechanism 2 is fixedly connected to a first vertical plate 3, and the other end of the bottom of the lifting mechanism 2 is fixedly connected to a second vertical plate 301. An adjustable distance mechanism 4 extending between the first vertical plate 3 and the second vertical plate 301 is fixedly connected to the second vertical plate 301. In order to automatically dig pits in the soil, a pit digging mechanism 5 is fixedly connected to the bottom of the adjustable distance mechanism 4. In order to easily insert the Pulsatilla chinensis plants into the pits dug by the pit digging mechanism 5, a seedling inserting mechanism 6 extending outside the second vertical plate 301 is fixedly connected to one side of the pit digging mechanism 5. The adjustable distance mechanism 4 drives the pit digging mechanism 5 and the seedling inserting mechanism 6 to adjust the horizontal spacing during the transplanting of Pulsatilla chinensis. The lifting mechanism 2 drives the adjustable distance mechanism 4 to reciprocate up and down, driving the pit digging mechanism 5 and the seedling inserting mechanism 6 to reciprocally dig pits and insert seedlings. A top plate 7 for installing a seedling feeding mechanism 8 is fixedly connected to the top wall of the fixed frame 1. In order to easily transport the Pulsatilla chinensis plants to be stored in the seedling inserting mechanism 6, a seedling feeding mechanism 8 extending between the two side walls of the top plate 7 is fixedly connected to one side wall of the top plate 7. A moving mechanism 9 extending to both sides of the fixed frame 1 is fixedly connected to the lower end of one side wall of the fixed frame 1. Starting the moving mechanism 9 can drive the device to move smoothly on a sloping terrain. A limiting frame 10 slidably connected to the seedling inserting mechanism 6 is fixedly connected to the middle of one end of the fixed frame 1. When operating the seedling inserting mechanism 6, the pulling rope 605 can be supported and limited by the limiting frame 10.

[0035] As Figure 2 and Figures 4 to 6As shown in the figure, in order to adjust the lateral spacing between the pit digging and the insertion of the Pulsatilla chinensis plants before transplantation, the distance adjusting mechanism 4 includes a lead screw 401 rotatably connected between the middle parts of the side walls of the first vertical plate 3 and the second vertical plate 301. The lead screw 401 is located between the vertical plates of the first vertical plate 3 and the second vertical plate 301, and the guide rod 403 is located between the inclined vertical plates of the first vertical plate 3 and the second vertical plate 301. Guide rods 403 are fixedly connected to both ends of the side walls of the first vertical plate 3 and the second vertical plate 301 respectively. The first vertical plate 3 and the second vertical plate 301 are each composed of a group of vertical plates and two groups of inclined vertical plates integrally formed on both sides of the vertical plates. The first vertical plate 3 and the second vertical plate 301 can install the lead screw 401 and the guide rods 403 symmetrically arranged on both sides of the lead screw 401, so that the guide rods 403 are inclined and form an acute angle with the lead screw 401. A nut block 404 is threadedly connected to the lead screw 401, and limit sliders 405 slidably connected to the guide rods 403 penetrate through both guide rods 403. When the nut block 404 moves on the lead screw 401, it can drive the two limit sliders 405 to translate and at the same time adjust the distance between the limit slider 405 and the nut block 404. A distance adjusting motor 402 is fixedly connected to the middle part of the outer side wall of the second vertical plate 301, and the output end of the distance adjusting motor 402 is fixedly connected to one end of the lead screw 401. When in use, turning on the distance adjusting motor 402 can drive the lead screw 401 to rotate. When the distance adjusting motor 402 rotates forward, it can drive the lead screw 401 to rotate forward, thereby driving the limit slider 405 to translate and move away from the nut block 404 at the same time. On the contrary, when the distance adjusting motor 402 rotates reversely, the limit slider 405 translates and approaches the nut block 404. A connecting rod 406 fixedly connected to the nut block 404 penetrates through the lower end of the nut block 404, and both ends of the connecting rod 406 penetrate through and are slidably connected to the lower ends of the limit sliders 405. The connecting rod 406 connects the nut block 404 and the two limit sliders 405. The nut block 404 drives the connecting rod 406 to move, and the connecting rod 406 slides on the limit slider 405 and pushes the limit slider 405 to translate, so that the three move simultaneously. The pit digging mechanism 5 includes motor seats 501 fixedly connected to the bottom walls of the nut block 404 and the limit sliders 405 respectively, and the seedling inserting mechanism 6 includes support rods 601 fixedly connected to the side walls of each motor seat 501. As can be seen from the above, the nut block 404 and the limit sliders 405 can automatically adjust the distance under the drive of the distance adjusting motor 402, that is, the distance adjusting motor 402 can be driven before transplantation, so that the motor seats 501 and the support rods 601 can both move accordingly to adjust the lateral spacing between the pit digging and the insertion of the Pulsatilla chinensis plants. After the distance adjustment is completed, the distance adjusting motor 402 is turned off.

[0036] As Figure 5As shown in the figure, in order to automatically dig holes in the transplanted soil, after the sleeve 504 is sleeved on the rotating rod 503, through holes that cooperate with the pin 506 are provided on both the rotating rod 503 and the sleeve 504. The pin 506 is passed through the through holes of the rotating rod 503 and the sleeve 504 to connect the two. A digging motor 502 is fixedly connected to the inner bottom wall of the motor base 501. The output end of the digging motor 502 is fixedly connected to the rotating rod 503 located below the motor base 501. When the digging motor 502 is turned on, it can drive the rotating rod 503 and the sleeve 504 sleeved thereon to rotate. The bottom of the sleeve 504 is fixedly connected to a drill bit 505 with a cross-section in a cross shape. A tip is provided at the lower end of the drill bit 505. Then, the drill bit 505 can smoothly drill into the soil to dig a hole under the drive of the sleeve 504.

[0037] As Figure 1 and Figures 6 to 8 shown, in order to transport the Pulsatilla plants to be transplanted, a seedling storage tray 809 is slidably inserted into the top of the top plate 7 on the other side of the vertical rod 805. The Pulsatilla plants to be transplanted are placed in the seedling storage tray 809 for temporary storage. A vertical rod 805 is fixedly connected to the top of the top plate 7. Three sets of collar rings 806 are slidably sleeved on the upper end of the vertical rod 805. The other ends of the three sets of collar rings 806 are respectively fixedly connected to a first baffle 807. Before transporting the Pulsatilla plants, first slide the collar rings 806 on the vertical rod 805 so that the distance between each set of collar rings 806 is the same as the distance of the adjusted seedling inserting mechanism 6. Second baffles 808 are rotatably connected to both side walls of the first baffle 807 through rotating shafts. Then, the distance between the first baffle 807 and the second baffle 808 is adjusted to be the same as the distance of the seedling inserting mechanism 6. Then, rotate the second baffle 808 and the rotating shaft along the side wall of the first baffle 807 so that the lower end of the second baffle 808 approaches the top of the fixed clamping plate 602. Since the side wall of the first baffle 807 and the rotating shaft are in interference connection, the rotated second baffle 808 can be temporarily positioned for the Pulsatilla plants to slide down. The seedling feeding mechanism 8 includes a transmission roller 801 rotatably connected between two sets of top plates 7. One end of the outer side wall of one set of top plates 7 is fixedly connected to a conveying motor 802, and the output end of the conveying motor 802 is fixedly connected to one end of the transmission roller 801. Before transplanting the Pulsatilla plants, take out three Pulsatilla plants from the seedling storage tray 809 and place them on the conveyor belts 804 in each set of first baffles 807 respectively. First, turn on the conveying motor 802 to drive the transmission roller 801 to rotate. A driven roller 803 opposite to the transmission roller 801 is rotatably connected between two sets of top plates 7 through a rotating shaft. Conveyor belts 804 are wound and connected to both the transmission roller 801 and the driven roller 803. Then, the conveyor belts 804 can drive the transmission roller 801 and the driven roller 803 to rotate synchronously. The conveyor belts 804 transport the Pulsatilla plants from one end of the driven roller 803 to one end of the transmission roller 801, and then are transported and slide down through the second baffle 808 to be stored in the respective fixed clamping plates 602 below.

[0038] As Figure 3 and Figure 6As shown, in order to enable the user to easily insert the Pulsatilla plants without frequent squatting and standing up, a fixed clamping plate 602 is fixedly connected to the other end of the support rod 601. A spring 603 is fixedly connected to the middle of the fixed clamping plate 602. The other end of the spring 603 is fixedly connected to a movable clamping plate 604. The upper ends of the fixed clamping plate 602 and the movable clamping plate 604 are both fixedly connected with enclosure inclined plates to prevent the Pulsatilla plants from falling out, and the lower ends are provided with enclosure bottom plates extending into the fixed clamping plate 602 and the movable clamping plate 604. When the spring 603 is in a contracted state, the fixed clamping plate 602 and the movable clamping plate 604 approach each other. As can be seen from the above, the three Pulsatilla plants sliding down from the second baffle 808 are temporarily stored between the fixed clamping plate 602 and the movable clamping plate 604. A rope 605 is arranged in the middle of the outer side wall of the movable clamping plate 604 and penetrates and is slidably connected to the side wall of the limit frame 10. The other end of the rope 605 is fixedly connected to a handle rod 606 located outside the side wall of the limit frame 10. The handle rod 606 is composed of a group of U-shaped rods and a cross bar fixedly connected to the middle of the U-shaped rods. The ends of the three ropes 605 are respectively fixedly connected to the two ends of the U-shaped rods and the cross bar. When the user pulls the handle rod 606 outwards to tighten the rope 605, the three movable clamping plates 604 are pulled, the spring 603 elongates accordingly, and the Pulsatilla plants temporarily stored between the fixed clamping plate 602 and the movable clamping plate 604 fall and are inserted into the dug pits.

[0039] As Figures 1 to 3 and Figure 6 shown, in order to perform the operations of digging pits and inserting Pulsatilla plants sequentially, the lifting mechanism 2 includes a timing starter 201 fixedly connected to the top wall of the fixed frame 1. The bottom of the timing starter 201 is fixedly connected with a hydraulic cylinder 202 extending below the top wall of the fixed frame 1. The telescopic ends of a group of hydraulic cylinders 202 are fixedly connected to the top wall of the second vertical plate 301, and the telescopic ends of the other two groups of hydraulic cylinders 202 are respectively fixedly connected to both ends of the top wall of the first vertical plate 3. Then, the first vertical plate 3 and the second vertical plate 301 can be lifted and lowered regularly under the drive of the hydraulic cylinder 202. The first vertical plate 3 is connected to the distance adjustment mechanism 4, that is, the pit digging mechanism 5 and the seedling inserting mechanism 6 can be lifted and lowered regularly driven by the hydraulic cylinder 202. The timing starter 201 can adjust the duration of the timing start and stop of the hydraulic cylinder 202 according to the moving speed of the device, so that the time interval of the start and stop of the hydraulic cylinder 202 corresponds to the distance advanced by the device. That is, the time interval for the pit digging mechanism 5 to descend and dig pits is the same as the time interval of the start and stop of the hydraulic cylinder 202. When the pit digging mechanism 5 descends to dig pits, the seedling inserting mechanism 6 also descends. At this time, when the user pulls the handle rod 606, the Pulsatilla plants can be easily inserted, without the user having to squat and stand up frequently, reducing the labor intensity. Similarly, the user can repeat the above steps to transport and insert and transplant another three Pulsatilla plants.

[0040] As Figures 1 to 2 and Figure 9As shown in the figure, on the outer side wall of one end of the fixing frame 1, a driving motor 902 is fixedly connected. The moving mechanism 9 includes a rotating shaft 901 that penetrates and is rotatably connected to the lower end of the fixing frame 1, and the output end of the driving motor 902 is fixedly connected to one end of the rotating shaft 901. When moving the device, the driving motor 902 is turned on to drive the rotating shaft 901 to rotate. One end of the rotating shaft 901 is fixedly connected to a driving wheel 903 located outside the fixing frame 1, and the other end of the rotating shaft 901 is fixedly connected to a driven wheel 904 located outside the fixing frame 1. Then, the rotating shaft 901 drives the driving wheel 903 and the driven wheel 904 to rotate synchronously. Tooth teeth that mesh with the crawler 905 are provided on both the driving wheel 903 and the driven wheel 904, so the crawler 905 also rotates accordingly. The other end of the crawler 905 is meshed with a rotating wheel 906 that is rotatably connected to the lower end of the fixing frame 1 through a rotating shaft, and the rotating wheels 906 are arranged oppositely at both ends of the fixing frame 1. Then, the two groups of rotating wheels 906 rotate along the fixing frame 1 driven by the crawler 905. A connecting plate 907 that is rotatably connected to the driving wheel 903 and rotatably connected to one group of rotating wheels 906 is provided, and both ends of the other group of connecting plates 907 are respectively rotatably connected to the driven wheel 904 and the rotating wheel 906. The synchronism between the driving motor 902 and the rotating wheel 906, and between the driven wheel 904 and the rotating wheel 906 can be improved through the connecting plate 907. Therefore, after the driving motor 902 is turned on, the user can push the device forward with less effort. The structural characteristics of the crawler 905 can adapt to the sloping terrain to enable the device to move smoothly, and while moving, pits are dug and Pulsatilla chinensis plants are inserted in sequence.

[0041] In summary, the cold-region Pulsatilla chinensis asexual propagation and transplanting device described in the present invention has the following advantages:

[0042] 1. The distance between the pit-digging mechanism for digging pits and the seedling-inserting mechanism for inserting seedlings can be automatically adjusted through the distance-adjusting mechanism, so as to meet the different requirements for the horizontal spacing of plants during the transplanting of cold-region Pulsatilla chinensis.

[0043] 2. The Pulsatilla chinensis transplanting plants are automatically transported to the seedling-inserting mechanism for temporary storage through the seedling-feeding mechanism. The lifting mechanism drives the pit-digging mechanism and the seedling-inserting mechanism to reciprocate up and down. The seedling-inserting mechanism is operated to release the temporarily stored Pulsatilla chinensis plants and insert them into the pits, without the need for workers to frequently squat and stand up for seedling insertion, reducing the labor intensity during transplanting.

[0044] 3. After the moving mechanism is adopted in this device, the device can smoothly pass through the sloping terrain during movement, improving the forward speed of the device.
