Balanced-lighting stereoscopic seedling raising rack

Abstract

A balanced-lighting stereoscopic seedling raising rack is characterized in that tray tier-based transfer racks are disposed at two ends of a stereoscopic seedling raising rack of floating raising trays, tray floating troughs in multiple tiers are mounted on transverse braces of the stereoscopic seedling raising rack, a chain is mounted on sprockets, arranged at the inner upper and lower ends of a support of each tray tier-based transfer rack, in an enclosing manner, the middle of each transfer rack is fixed on a holder, sliders on each holder are fastened to a slide post of a support, a rope lock on the lower portion of each holder is fixed on the corresponding chain, a counting probe for counting the seedling raising trays is mounted at the front end of each transfer rack, a tray pushing cylinder is mounted at the rear end of each transfer rack, a tier positioning probe for the tray floating troughs is mounted at the rear end of each support, and an air pump and an electrical box are mounted on the support of one tray tier-based transfer device. The seedling raising trays float in the seedling raising troughs and experience small motion resistance, the seedling raising trays can be moved between the transfer racks and the seedling raising troughs through only one cylinder, the transfer racks can be driven to raise and lower the seedling raising trays by a single motor, manufacturing cost of equipment cost is low, and consumption is low; the design of tier positioning and tray counting probe control is adopted, and automatic production control is achieved.

Description

technical field [0001] The invention belongs to the technical field of floating seedling raising equipment in agricultural production, and relates to a three-dimensional seedling raising rack with balanced lighting. Background technique [0002] Floating seedlings is a widely used technology in agricultural production. The basic procedure is to plant the seeds of crops in a floating seedling tray made of plastic foam with multiple seed planting holes, and place the seedling tray in a container filled with nutrients. Let the seedling tray float on the water surface, and the matrix in the planting hole absorbs the nutrient solution for the seeds to germinate and grow, and then transplant the seedlings to the field after they grow up. At present, this method of raising seedlings is restricted by the lighting requirements of plants, and most of them are carried out in a single layer on one piece of land, occupying a large area of ​​land. In order to increase the number of seedl...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problems in the prior art that the self-controlled three-dimensional seedling tray rack has a complex structure, many cylinders are used, the manufacturing cost is high, the power consumption is large, and it is difficult to popularize in actual production, and it provides a three-dimensional lighting balance Seedling raising rack, the floating seedling raising tray of the rack is equipped with seedling tray shifting racks at both ends of the rack, and the vertical bracing bar of the vertical seedling rack is composed of a horizontal strut and a vertical strut, and a seedling tray floating groove is installed on the horizontal strut , the seedling tray floating tank has multiple layers, the two ends of the seedling tray floating tank are installed with seedling tray slides, and a leaf trimmer is installed above the seedling tray floating slot on the lowest layer, the floating seedling tray is square, close together, floating on the In the floating tank of the seedling tray, there are rotating shafts installed at the upper and lower ends of the support of the seedling tray moving layer frame. The upper end of the rotating shaft is connected to the motor. Two sets of sprockets are installed on the rotating shaft. A vertical sliding column is installed on the upper part, the middle part of the moving rack is fixed on the fixed frame, sliders are installed on the upper and lower ends of the fixed frame, and the slider is stuck on the sliding column, and a connecting rod is installed on the lower part of the fixed frame. A rope lock is installed at the rear end of the rack, and the rope lock is fixed on the chain. The counting sensor head of the seedling raising tray is installed on the front end of the moving rack, and the push plate cylinder is installed on the rear end. A push plate is installed on the shaft head of the push plate cylinder. The layer positioning induction head of the seedling tray floating tank is installed at the rear end of the bracket, and an air pump and an electric control box are installed on the bracket of one of the seedling tray layer shifting devices
