Description

Technical Field

[0001] This utility model relates to the field of seedling technology, specifically to a substrate soil filling device for seedling trays in agricultural seedling cultivation. Background Technology

[0002] A seedling tray is a plastic product used for cultivating seedlings. The tray consists of a main body composed of several seedling cups arranged in a row, with drainage holes at the bottom of each cup. During seedling cultivation, seedlings are first grown in the cups, one seedling per cup, and then transplanted to become mature seedlings. Seedling trays produce uniform seedling emergence, maintaining consistent plant growth, and have become an important tool in factory-scale seedling production, ensuring rapid and large-scale production. However, the traditional method of filling seedling trays involves manually shoveling substrate into each planting cell, then manually removing excess substrate using a board. This process is labor-intensive and inefficient, hindering factory-scale seedling production. Utility Model Content

During the transportation of the seedling tray, the electro-optical switch sensor under the hopper 9 detects the seedling tray and drives the servo motor 19 to rotate the shaft 20 and the discharge plate 21, thereby transporting the substrate soil in the discharge hopper 9 downward and falling from the bottom onto the seedling tray. The substrate soil enters the seedling hole. The scraper 15 scrapes off the excess substrate soil on the seedling tray. When the electro-optical switch sensor at the bottom of the cross support plate 5 detects the seedling tray, it drives the electric push rod 8 to extend quickly, driving the pressing plate 7 to move downward. The pressing block 13 at the bottom of the pressing plate 7 presses the substrate soil in the seedling hole out of the planting hole, completing the filling and pressing of the substrate soil on the seedling tray, effectively improving the filling efficiency.
