Industrialized seedling raising system based on stacked tray darkroom technology

Abstract

The invention discloses an industrial seedling raising system based on a disc stacking darkroom technology. A synchronous motor is installed at one end of a chain transmission box through a motor base, a plurality of fixed insertion columns are welded to the opposite ends of two annular conveying belts at equal intervals, and a servo motor output shaft is sleeved with a supporting bearing plate in a clamped mode; limiting electromagnets are symmetrically embedded in the two sides of the top end of the supporting bearing plate, the top ends of the two limiting electromagnets are connected with a seedling raising plate, infrared induction switches are symmetrically clamped to the two sides of one end of the seedling raising plate, and a feedback plate is installed at one end of the linkage moving frame. The servo motor drives the seedling raising plates to rotate reversely at a slow speed, so that the situation that seeds fall off due to overturning of the seedling raising plates during circulation can be avoided, and the situation that the positions of the seedling raising plates are continuously and circularly changed, so that the situation that the germination difference of the seeds in the multiple seedling raising plates is large due to fixed positions is avoided.

Description

technical field [0001] The invention relates to the technical field of darkroom raising seedlings, in particular to a factory-like seedling raising system based on the technology of stacked disc darkrooms. Background technique [0002] With the development of science and technology, agriculture has gradually realized mechanization, modernization and scientificization. Especially in the cultivation of rice, the technology of indoor seedling and seedling raising has become more and more mature. Rice is a rice crop. 0.5-1.5 meters, depending on the variety, rice likes high temperature, high humidity, and short sunshine, and the soil requirements are not strict. Now, when the medium rice is machine-planted, the dark room is generally used for germination and seedling. [0003] However, at present, when germinating seedlings in the dark room, the placement position of the seedling trays is relatively fixed, which leads to certain differences in the environment where the seeds in ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an industrialized seedling raising system based on stacked tray darkroom technology, which can effectively solve the problems of general seedling raising trays when germination and seedling raising in darkrooms are proposed in the above-mentioned background technology. The placement position is relatively fixed, which leads to certain differences in the environment in which the seeds in different positions germinate, which makes the germination of the same batch of seeds uneven, resulting in a large difference in growth rate when they are subsequently transplanted into the greenhouse, thus affecting the quality of seedling cultivation. problem of effect
