Description

Technical Field

[0001] The utility model relates to the technical field of tobacco seedling transplanting equipment, in particular to a tobacco seedling transplanter capable of being operated by a single person. Background Art

[0002] Tobacco cultivation is one of the main cash crops in some rural areas, significantly contributing to farmers' income growth and prosperity. Currently, tobacco cultivation primarily involves raising seedlings before transplanting, a crucial step in the process. Transplanting involves digging holes, watering, planting the seedlings, and covering the soil, a complex process. Therefore, transplanting seedlings in my country currently relies primarily on manual labor, with a low level of mechanization. However, manual labor is labor-intensive and results in low transplanting efficiency.

[0003] To this end, technicians have developed some auxiliary equipment for transplanting tobacco seedlings, such as patent number 2023215592834, named handheld tobacco seedling transplanter. The tobacco seedling transplanter can be used to realize digging holes, placing seedlings and covering soil during tobacco seedling transplanting. The operator holds the handle and inserts the hole-opening cone at the lower end of the transplanter into the soil. Then the operator holds the pulling handle tightly, and the pulling handle pulls the sliding sleeve through the pull rod. The sliding sleeve moves upward and is pulled by the pull rod to form an opening piece of the hole-opening cone. The opening piece holds the soil to form a tobacco seedling transplanting hole. Then, the tobacco seedlings are put in from the opening at the upper end of the lower tube and fall directly into the transplanting hole along the inner cavity of the lower tube. After that, the operator releases the pulling handle, the opening piece is reset, and the loose soil held open by the opening piece naturally falls back to cover the roots of the tobacco seedlings, realizing the soil covering operation. However, when the tobacco seedling transplanter is actually used, the operator holds the pulling handle to open the soil with the opening piece. In order to keep the tobacco seedling transplanting hole open and to facilitate the tobacco seedlings to pass through the inner cavity of the lower tube and fall into the transplanting hole smoothly, the opening piece must be kept in the open state. This requires the operator to keep holding the pulling handle tightly with both hands for a long time, which means that the seedling transplanting operation requires assistance from someone.

[0004] Moreover, the tobacco seedling transplanter cannot realize the watering operation during transplanting tobacco seedlings, and watering has a great influence on the survival rate of tobacco seedlings after transplanting. Therefore, after transplanting tobacco seedlings using the tobacco seedling transplanter, manual watering is still required. However, when watering after covering the tobacco seedlings with soil, the water evaporates quickly, which is not conducive to the absorption of the tobacco seedlings and affects the survival rate of the transplanted tobacco seedlings. Utility Model Content

[0005] To sum up, in order to overcome the shortcomings of the existing technical problems, the utility model provides a single-person operated tobacco seedling transplanter, which pulls the opening piece of the hole-opening cone through a pedal that can move downward along the seedling tube. The operator can step on the pedal to make the opening piece open the soil to form a transplanting hole, and keep the opening piece open, thereby freeing the operator's hands and making it convenient for the operator to place the tobacco seedlings from the seedling tube into the transplanting hole, realizing single-person operation when transplanting tobacco seedlings.

The slider 11 cooperates with the slide groove 9 to achieve a relative sliding connection between the mobile ring 10 and the seedling tube 1. The chute 9 is arranged in an L-shape on the outer wall of the seedling tube 1. It has a vertical portion arranged along the high end direction of the seedling tube 1 and a folded portion arranged along the circumference of the seedling tube 1. The vertical portion is connected to the folded portion. When the slider 11 moves in conjunction with the vertical portion, the mobile ring 10 moves up and down along the vertical portion. When the slider 11 cooperates with the folded portion, the mobile ring 10 remains in position relative to the seedling tube 1. Two return springs 12 are provided between the support ring 8 and the mobile ring 10. The return springs 12 are arranged along the circumference of the seedling tube 1. One end of the return spring 12 is connected to the support ring 8, and the other end of the return spring 12 is connected to the mobile ring 10.

[0028] One of the opening pieces of the hole-opening cone 6 is provided with a watering hole 13 connected to the inner cavity of the hole-opening cone 6. A watering valve 15 is provided on the pedal 5. The water outlet of the watering valve 15 is connected to the watering hole 13 through a water pipe, and the water inlet of the watering valve 15 is connected to the water supply tank 14 through a water pipe. The watering valve 15 includes a valve hole provided in the pedal 5 and connected to the top and bottom surfaces of the pedal 5. The valve hole is a stepped hole, and the direction from the top to the bottom of the pedal 5 is respectively an upper valve hole 16 and a lower valve hole 17. The inner diameter of the upper valve hole 16 is smaller than the inner diameter of the lower valve hole 17. The lower part of the lower valve hole 17 is threadedly connected to a joint, and the joint is connected to the watering hole 13 through a water pipe. A valve ball 18 for sealing the lower end opening of the upper valve hole 16 is provided in the lower valve hole 17. A reset elastic member 20 is provided between the valve ball 18 and the joint.

[0029] When in use, the operator carries the water supply box 14 filled with water on his back, and then drives the hole-opening cone 6 at the lower end of the seedling-planting tube 1 into the soil by pulling the handle 2. Then, the operator steps on the valve cap 21 of the pedal 5 provided with the watering valve 15, so that the pedal 5 drives the movable ring 10 to move downward, and the movable ring 10 pulls the pull rope 7. Under the pulling action of the pull rope 7, the opening piece constituting the hole-opening cone 6 swings from the inside to the outside relative to the lower end of the seedling-planting tube 1, thereby opening the soil to form a tobacco seedling transplanting hole. Because the operator steps on the pedal 5, he steps on the valve cap 21 of the watering valve 15, so that the valve cap 21 and the valve stem 19 move downward relative to the pedal 5, and the valve stem 19 pushes open the valve ball 18, so that the upper valve hole 16 is connected with the lower valve hole 17, so that the water in the water supply box 14 flows into the tobacco seedling transplanting hole along the water pipe and the watering hole 13 on the opening piece. In other words, the hole-opening cone 6 of the utility model completes watering in the tobacco seedling transplanting hole at the same time as school starts.

[0030] Then, the operator puts the tobacco seedlings into the seedling-releasing port 3 at the upper end of the seedling-releasing tube 1, and the tobacco seedlings fall into the opened tobacco seedling transplanting hole along the inner cavity of the seedling-releasing tube 1. Finally, the operator releases the pedal 5, and the movable ring 10 is reset under the action of the reset spring 12. The opening and closing pieces of the hole-opening cone 6 swing from outside to inside. At this time, the soil supported by the opening and closing pieces naturally falls back to cover the roots of the tobacco seedlings, realizing the soil covering operation. The tobacco seedling transplanting operation is now completed. When the operator releases the pedal 5, he should release the pedal 5 slowly, which can effectively prevent the opening and closing pieces of the hole-opening cone 6 from pinching the tobacco seedlings when resetting.

[0031] When the watering hole 16 is opened, the watering hole 16 is closed, and the watering hole 16 is closed, and the watering hole 16 is closed.
