Tray automatic seedling-feeding device

Abstract

The invention relates to an automatic seedling feeding device for a direct inserting type culture pot seedling grafting machine. The invention aims to provide a device capable of automatically and effectively cutting hole seedling growing points and realizing the full automatic seedling feeding for the direct inserting grafting machine. The device is also characterized by accurate positioning, correct cutting position and convenient operation. The invention adopts a technical proposal that a tray automatic seedling feeding device comprises an installation plate, a tray transporting unit, a hole seedling transporting unit, a hole seedling treatment unit and a control unit. In the tray transporting unit, a first step motor drives a conveyer belt to move. In the hole seedling transporting unit, a second step motor drives a first guide rod cylinder through a straight line driving mechanism; a first gas claw group and a second gas claw group are arranged on the first guide rod cylinder; and the two gas claw groups respectively have a pair of seedling gripping paws and a pair of stem cutting blades. A second mounting rack and a second connecting plate are arranged in the hole seedling treatment unit; a third gas claw group and a second guide rod cylinder are arranged on the second connecting plate; and the third gas claw group and the second guide rod cylinder respectively have a pair of positioning paws and a pair of blades.

Description

technical field [0001] The invention relates to an auxiliary device for growing seedlings of horticulture and vegetables, in particular to an automatic seedling feeding device for a straight-insert nutritional pot seedling grafting machine. Background technique [0002] The in-line grafting machine is a seedling raising machine widely used in the fruit and vegetable seedling industry at present. It has the characteristics of improving work efficiency and work quality and reducing labor intensity. Present in-line grafting machines have relatively high requirements on the cotyledon direction and the height of the growth point when seedlings are loaded, so in practice, manual seedlings are used. In the process of artificial seedling loading, the cotyledon growth point Y of each hole seedling in the hole plate is generally removed manually (each hole plate cultivates a group of hole seedlings that are horizontally and vertically aligned and neatly arranged; as shown in Figure 17...

AI Technical Summary

Problems solved by technology

In the process of artificial seedling loading, the cotyledon growth point Y of each hole seedling in the hole plate is generally removed manually (each hole plate cultivates a group of hole seedlings that are horizontally and vertically aligned and neatly arranged; as shown in Figure 17 shown), and jacking at the removal site, and then grafting the seedlings, this is time-consuming and laborious, and the work efficiency is low and the labor intensity is high
