Description

Technical Field

[0001] The utility model relates to the technical field of automatic sowing, in particular to an improved automatic tray supply machine. Background Art

[0002] In response to the requirements of automation and efficiency in seedling cultivation, various seedling tray seeding and sowing production lines have been developed. Such production lines generally include seedling tray supply, bottom soil laying, compaction, sowing, topsoil covering, water spraying, stacked tray removal and other processes. Among these many processes, seedling tray supply, as the primary key link, affects the running speed of the entire production line. During the transmission seedling tray supply process, one person is required to transport the stacked seedling trays, and then another person repeatedly arranges the trays. In order to save manpower, an automatic and uninterrupted repeated tray arrangement device has been developed. For example, the patent with publication number CN 213095123 U discloses an automatic tray supply machine, the positions of the left limit plate (14), the right limit plate (15) and the end baffle (16) of which are not adjustable, and the tray claws are relatively fixed relative to the horizontal connecting rod, and the position of the tray claws cannot be changed. The automatic tray supply work of only one specification of seedling tray can be adapted, and the practicality is low. Utility Model Content

At this time, the lowest seedling tray can be output from front to back along with the first conveyor belt, and then the paddle is reversed and reset, and the upper seedling tray automatically falls onto the first conveyor belt, and then the other seedling trays except the lowest seedling tray are pushed up for a distance again by analogy;

[0010] By adjusting the position of the paddle on the paddle bracket and the position of the guide plate on the frame, seedling trays of different widths can be guided, so that seedling trays of different specifications can be adapted, thereby improving the practicability of the tray supply machine.
