With the popularization of automated transplanters, the processes of delivering and retrieving seedlings have been automated, replacing manual labor with mechanized equipment. This effectively improves labor efficiency and reduces the intensity of manual labor. The function of the seedling delivery device is to deliver the plug trays containing seedlings to the designated location. Therefore, improving the accuracy of controlling the position of the seedling trays is the key to improving the performance of the seedling delivery device. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] Please refer to Figure 1 and Figure 2 This utility model provides a seedling delivery device for transplanting equipment, including a frame 1 and a seedling tray 2. Multiple sprockets 3 are mounted on the frame 1, connected by chains 4. In this embodiment, two sets of sprockets 3 and chains 4 are symmetrically arranged on the left and right sides of the frame 1. A stop bar 6 is connected at both ends to the chains 4 on both sides. The symmetrical arrangement of the two sets of chain drive mechanisms improves the smoothness of the transmission. The sprockets 3 are driven to rotate by a drive motor 5. The drive motor 5 is a servo motor, which improves control precision. A stop bar 6 is mounted on the chain 4. The seedling tray 2 slides on the frame 1. The sprockets 3 can drive the chains 4 and stop bar 6 to move, and the stop bar 6 pushes the seedling tray 2 to slide on the frame 1. The movement distance of the stop bar 6 is controlled by controlling the rotation of the sprockets 3, thereby controlling the position of the seedling tray 2. An angle sensor 7 is installed on the sprocket 3 to measure the rotation angle of the sprocket 3. The rotation angle of the sprocket 3 is measured to accurately determine the moving position of the stop bar 6 on the chain 4. Together with the drive motor 5, it can achieve precise control of the position of the stop bar 6.
[0026] Multiple baffles 6 are evenly spaced on the chain 4. The baffles 6 move cyclically along the rotation direction of the chain 4, so that a seedling tray 2 can be placed between two adjacent baffles 6 on the frame 1, reducing the waiting time between two seedling trays 2.
[0027] In this embodiment, a tray 101 is provided on the frame 1, and a limiting strip 102 is provided on the tray 101. The seedling tray 2 is placed on the tray 101 and is slidably connected to the limiting strip 102. A stop bar 6 pushes the seedling tray 2 from the front end to the rear end of the frame 1. The tray 101 at the rear end of the frame 1 has a downwardly curved arc structure, so that when the seedling tray 2 reaches the rear end of the frame 1, it automatically tilts under the action of the arc structure, making it easier to pick up the seedlings. A pressure rod 8 is provided above the tray 101. When the seedling tray 2 moves to the rear end of the frame 1, the pressure rod 8 presses down on the seedling tray 2, firmly controlling the seedling tray 2 to keep it in a fixed position and prevent shaking. In addition, a seedling support rod 9 is also provided above the tray 101 at the rear end of the frame 1 to prevent the seedlings from bending downwards when the seedling tray 2 tilts, thus protecting the integrity of the seedlings.
[0028] To further improve the movement range of the seedling delivery device, a slide rail 10 and a drive mechanism 11 are provided at the bottom of the frame 1. The drive mechanism 11 is a lead screw motor that drives the frame 1 to perform linear motion. Moreover, the lead screw motor is a servo motor with higher control precision. The slide rail 10 is perpendicular to the direction of the chain 4. The drive mechanism 11 drives the frame 1 to slide and connect it with the slide rail 10, so that the seedling trays 2 on the frame 1 can be displaced in the left and right directions.
[0029] During operation, the stop lever 6 drives the seedling tray 2 to move laterally under the drive of the chain 4, and the frame 1 is set on the slide rail 10 to drive the seedling tray 2 to move longitudinally. The purpose of delivering seedlings is achieved by precisely controlling the lateral and longitudinal movement of the seedling tray 2.
[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
