Description

Technical Field

[0001] This utility model relates to the technical field of tobacco seedling transplanting equipment, and in particular to a seedling feeding device for a tobacco seedling transplanter. Background Technology

[0002] In the current tobacco seedling transplanting process, manual transplanting is the most common method. This manual transplanting involves bending over to place the seedlings, walking upright, bending over again to place them, and walking upright again, repeating this cycle until the entire tobacco field is transplanted. This prolonged and repetitive labor can cause damage to the tobacco farmers' backs and even their bodies. In addition, in many areas, the mechanization level of tobacco seedling transplanting is almost zero, relying entirely on manual transplanting. This results in high labor intensity and costs, is time-consuming and labor-intensive, and inefficient, requiring approximately 1.2 workers per mu (a Chinese unit of area, approximately 0.067 hectares) and costing around 150 yuan per mu. Utility Model Content

[0003] To solve or partially solve the problems existing in related technologies, this utility model provides a seedling placement device for a tobacco seedling transplanter, which aims to improve the efficiency of tobacco seedling placement and reduce the labor intensity of workers.

[0004] The seedling feeding device of the above-mentioned tobacco seedling transplanter includes a seedling feeding mounting frame, a seedling feeding motor, a fixed turntable, a movable turntable, a seedling dropping cup, and a seedling storage tray;

[0005] A fixed turntable is fixedly installed on the seedling supply mounting frame. A movable turntable is movably installed above the fixed turntable. Seedling cups are arranged in a circle on the movable turntable, and the lower end of the seedling cups extends downward to the fixed turntable. The fixed turntable is provided with seedling holes. A seedling storage tray is provided above the seedling cups. The seedling storage tray is semi-circular.

[0006] The seedling supply mounting frame is equipped with a seedling supply motor for driving the movable turntable to rotate.

[0007] In some designs, the seedling cup is equipped with a heightening cup.

[0008] In some designs, two movable turntables are provided, spaced apart along the vertical direction.

[0009] In some designs, eight seedling cups are provided.

[0010] In some designs, spring pieces are spaced around the circumference of the seedling cup. The lower end of each spring piece is fixed to the seedling cup, and the upper end of each spring piece is movably connected to the seedling cup. The upper ends of all the spring pieces are connected together by a ring-shaped connector, which is connected to a collar fitted on the outside of the seedling cup.

[0011] The technical solution provided by this utility model can include the following beneficial effects:

[0012] The seedling feeding motor of this application drives the seedling cup to rotate continuously through a movable turntable. When the seedling cup rotates to the seedling hole, the tobacco seedlings automatically fall downwards to complete the seedling feeding action. It is convenient to use, effectively improves the work efficiency of seedling feeding staff, and reduces the labor intensity of staff.

[0013] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0021] Please see Figure 1 and Figure 2This application provides a seedling feeding device for a tobacco seedling transplanter, including a seedling feeding frame 1, a seedling feeding motor 2, a fixed turntable 3, a movable turntable 4, and seedling cups 5. The fixed turntable 3 is fixedly installed on the seedling feeding frame 1, and the movable turntable 4 is movably installed above the fixed turntable 3. The seedling cups 5 are arranged in a circle on the movable turntable 4. Preferably, there are eight seedling cups 5, and the lower end of the seedling cups 5 extends downward to the fixed turntable 3. Preferably, the seedling cups 5 are provided with a heightening cup 7, and the fixed part of the heightening cup 7 is funnel-shaped, which is conducive to the workers accurately feeding tobacco seedlings into the seedling cups 5. The fixed turntable 3 is provided with a seedling hole 31. The seedling feeding frame 1 is provided with a seedling feeding motor 2 for driving the movable turntable 4 to rotate.

[0022] During operation, tobacco seedlings are manually or otherwise placed into the individual seedling cups 5. Then, the seedling supply motor 2 is activated, which drives the seedling cups 5 to rotate via the movable turntable 4. When the seedling cup 5 moves to the position corresponding to the seedling hole 31, the tobacco seedling falls down from the seedling hole 31, thus completing the seedling placement operation. This achieves mechanized seedling placement, eliminating the need for workers to bend over, improving seedling placement efficiency, and reducing the labor intensity of workers. In use, the interval between adjacent seedling cups 5 moving to the seedling hole 31 can be controlled by adjusting the speed of the seedling supply motor 2, thereby controlling the seedling placement interval and ensuring precision.

[0023] In this embodiment, a seedling storage tray 6 is provided above the seedling cup 5. The seedling storage tray 6 is semi-circular and has multiple cavities. When manually placing seedlings, the tobacco seedlings can be temporarily stored on the seedling storage tray 6, making it convenient for staff to place the tobacco seedlings into the seedling cup 5.

[0024] In this embodiment, two movable turntables are provided, spaced apart in the vertical direction. The two movable turntables 4 simultaneously fix all the seedling cups 5, effectively avoiding the technical problem of the seedling cups 5 tilting during rotation.

[0025] In some specific implementations, such as Figure 3As shown, spring pieces 51 are spaced around the circumference of the seedling cup 5. The lower end of the spring piece 51 is fixed to the inner wall of the seedling cup 5, and the upper end of the spring piece 51 is movably connected to the inner wall of the seedling cup 5. The upper ends of all the spring pieces 51 are connected as one piece by a ring-shaped connector. A collar 53 is provided on the outer side of the seedling cup 5. The collar 53 is fixed in position by tightly fitting the seedling cup 5. The seedling cup 5 is provided with a clearance hole 52 extending vertically. After the connecting rod passes through the clearance hole 52, its two ends are connected to the connector and the collar 53 respectively. In use, the position of the collar 53 can be adjusted up and down, thereby driving the connector to move up and down, so that the spring piece 51 bends in the seedling cup 5, thereby adjusting the inner diameter of the seedling cup 5. In this way, when the tobacco seedlings are small, the spring pieces 51 prevent the tobacco seedlings from tilting in the seedling cup 5, thereby ensuring that the tobacco seedlings can fall vertically when seedlings are planted.

[0026] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
