Description

Technical Field

[0001] The utility model relates to the technical field of soil covering equipment, in particular to a soil laying device for a seedling tray. Background Art

[0002] Plug tray seedling technology is a modern seedling technology that uses light-substrate soilless materials such as peat and vermiculite as seedling substrate, precise sowing, one seed per hole, and one-time seedling formation. Plug tray seedling cultivation increases seedling density, facilitates intensive management, improves greenhouse utilization, and reduces production costs. Due to unified sowing and management, the growth and development of seedlings are consistent, the quality of seedlings is improved, and it is conducive to large-scale production. In the process of plug tray seedling cultivation, in order to increase the seed germination rate, the surface of the seeds needs to be covered with soil. However, the covering process generally uses manual covering, which causes high labor intensity for the staff and cannot effectively improve the efficiency of covering. In addition, the covering depth is uneven, which causes the covered soil layer to easily clump, affecting the seed germination rate, thereby seriously affecting large-scale application.

[0003] The existing public technology has a publication number of: CN213939048U, which discloses a seedling tray soil covering device for agricultural production, and provides a seedling tray soil covering device for agricultural production that does not require manual soil covering, has high soil covering efficiency, uniform soil covering depth, and does not affect the seed emergence rate. The utility model provides such a seedling tray soil covering device for agricultural production, including a support frame and a soil covering mechanism, etc., and the top of the support frame is provided with a soil covering mechanism. Through the cooperation between the fourth rotating shaft, the arc block, the elastic member and the nesting plate, the fourth rotating shaft drives the arc block to rotate, when the arc block rotates to press the nesting plate, the elastic member is compressed, and the nesting plate slides downward to nest the nutrient soil in the seedling tray, and when the arc block rotates to not contact the nesting plate, under the reset action of the elastic member, the nesting plate slides upward to reset, thereby improving the nesting efficiency and ensuring that the soil covering depth on the seedling tray is consistent.

[0004] Although the above patent can improve the efficiency of nesting, there are still some shortcomings in its use. First, the soil covering structure of the patent cannot quantitatively cover the seedling tray with soil, which easily leads to excessive soil covering of the seedling tray. Secondly, the patent adopts the method of transporting organic soil to the seedling tray at one time and then covering the soil with a scraper. The lack of a certain compaction structure may cause hollow areas of soil in the seedling tray, which is not conducive to the subsequent growth of seedlings. With respect to the problems in the relevant technology, no effective solution has been proposed yet. Utility Model Content
