Description

Technical Field

[0001] The utility model relates to a tobacco seedling-raising tray which is convenient to pick up and place, and belongs to the field of seedling-raising tools. Background Technique

[0002] Wet tray seedling raising is a common agricultural technique in tobacco seedling raising. It usually uses a multi-pot combined seedling-raising tray as a planting tray. After filling the seedling-raising substrate and coated seeds in its inverted conical seedling pots, it is placed on a dry and flat ground surface, and a spraying system arranged above the seedling-raising tray provides water for it. However, since the spraying system cannot achieve uniform irrigation, in order to meet the water requirements of all seedling pots, excessive water is often sprayed. The excess water will flow out through the drainage holes at the bottom of the seedling pots of the seedling-raising tray, reducing the water utilization rate. At the same time, the runoff generated at the edge of the seedling-raising tray will also cause water to be lost to the ground surface and cannot be utilized. At the same time, when the existing seedling-raising trays are placed, the seedling-raising trays are placed as closely as possible to avoid water leakage between the seedling-raising trays. However, the fixed height of the seedling-raising trays on the tray is certain, so it is not easy to pick up a certain seedling-raising tray between the closely placed seedling-raising trays. For example, when the tobacco seedlings in a certain seedling-raising tray are diseased, etc., it is not convenient to take them out.

[0003] Therefore, it is necessary to design a tobacco seedling-raising tray that can improve the water utilization rate and is also convenient to pick up and place the seedling-raising tray. Content of the Utility Model

Detailed implementation manners

[0031] Hereinafter, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail. It should be understood that the preferred embodiments are only for explaining the present utility model, rather than limiting the protection scope of the present utility model.

[0032] As Figures 1-9 shown, a tobacco seedling-raising tray that is convenient for taking and placing disclosed by the present utility model includes a mutually cooperating tray 1 and a seedling-raising tray 2. Seedling-raising cells 3 are distributed on the seedling-raising tray 2. Water seepage holes are provided at the bottom of the seedling-raising cells 3. Support blocks 4 for the seedling-raising tray 2 are provided on the tray 1. An automatic spring-up device is provided on the support blocks 4. After pressing down the seedling-raising tray 2, the automatic spring-up device automatically lifts the seedling-raising tray 2. With such a structure, the tray can receive the excess water that seeps down during spraying. At the same time, by providing an automatic spring-up device on the support blocks 4, when it is necessary to take out a certain seedling-raising tray 2 from the horizontally placed seedling-raising trays 2, the seedling-raising tray 2 is pressed down. Under the action of the automatic spring-up device, the support blocks 4 spring up and extend upward, lifting the seedling-raising tray 2 upward, creating a height difference from other seedling-raising trays 2, which is conducive to picking up the seedling-raising tray 2. To facilitate clarifying the pressing position of the seedling-raising tray 2, the support blocks 4 are preferably installed at the corners of the tray 1, corresponding to the corners of the seedling-raising tray 2.

[0033] Furthermore, the automatic spring-up device includes a mounting sleeve 5, a compression spring 7, and a connecting rod 7. Specifically,

When it is necessary to take out the seedling tray 2, the seedling tray 2 is pressed downward and then released. Under the action of the ring-shaped guide groove 9 and the compression spring 6, the fixing column 8 first moves to the right side of the ring-shaped guide groove 9, and then, under the continuous pushing of the compression spring 6, the fixing column 8 moves downward from the right-side ring-shaped guide groove 9 until it locks with the second locking position 11. During this process, the support block 4 is popped out by the compression spring 6, so as to realize the elevation of the seedling tray 2. The specific schematic diagram is as shown in Figures 6-8 shown, Figure 9 which is a schematic diagram of the position change from the second locking position 11 to the first locking position 10. During this process, there are guide surfaces on the inner wall of the ring-shaped guide groove 9 to guide the fixing column 8 to move only in a certain direction. For example, on the upper inner wall on the right side of the first locking position 10, there is a guide surface Ⅰ that guides the fixing column 8 to move obliquely upward to the right after being pressed down. The top of the guide surface Ⅰ corresponds to the upward moving guide groove. When in the second locking position 11, there is a guide surface Ⅱ on the upper side of the second locking position 11 that can only guide the fixing column 8 to the left when being pressed down by force, and there is a guide surface Ⅲ on the left side of the first locking position 10 that guides the fixing column 8 to the position of the first locking position 10.
