Description

Technical Field

[0001] The invention relates to the technical field of seedling tray disinfection devices, and in particular to an agricultural vegetable seedling tray soaking and disinfection device. Background Art

[0002] Seedling cultivation is a key technical link in vegetable production. Intensive vegetable seedling cultivation technology mainly uses light substrate as a seedling carrier and plug trays as the main container for production. According to production needs, plug trays with different hole sizes are selected for different vegetable varieties, seedling seasons, and cultivation modes. In order to increase the output per unit area, plug trays with more holes should be selected as much as possible without affecting the quality of seedling cultivation. At present, the materials used to make plug trays are generally polystyrene foam, polystyrene, polyvinyl chloride and polypropylene, and the manufacturing methods include blow molding and injection molding. Vegetable seedlings are mostly made of polystyrene materials, which have the characteristics of anti-brittle cracking, aging resistance, and non-deformation. Polystyrene foam seedling trays can also be used for floating seedling cultivation.

[0003] In order to save costs, seedling trays are usually reused. Before use, the seedling trays need to be disinfected, and immersion disinfection is generally used. For example, Chinese patent announcement No. CN114225069A discloses a "foam seedling tray immersion disinfection device for agricultural vegetable seedlings". After the first movable plate and the first fixed plate can clamp the seedling tray, the cylinder drives the first fixed plate to move up and down, so that the seedling tray can move downward to the first fixed frame containing disinfectant for immersion. After the immersion is completed, the upper part is driven by the cylinder to move upward, and the first fixed rod and the second fixed plate are in contact and cooperate, so that the seedling tray is detached and falls on the sliding frame. In this way, the seedling tray can be automatically moved, and there is no need to manually immerse and put away the seedling tray;

[0004] However, in actual use, since the seedling tray needs to be filled with nutrient soil during the seedling raising process, when the seedling tray is soaked and disinfected, the residual soil and sand and gravel on the seedling tray will fall into the immersion device. As the use time increases, the soil and sand in the immersion device accumulate, affecting the use of the device, and after the soaking is completed, some soil and organic matter will still adhere to the seedling tray, which will pollute the subsequent seedling raising and easily cause disease in the vegetable seedlings. Summary of the invention
