A device for ejecting seedlings from plug trays to protect pots

Abstract

The invention discloses a plug seedling ejecting and picking apparatus capable of protecting pot bodies. The apparatus comprises a pressing plate, a base, a seedling picking shovel and pot protecting holders; the pressing plate comprises a handle, a crossbeam and an external frame; the base comprises a base plate as well as positioning pins and ejecting pins which are fixedly installed on the base plate; the pot protecting holders are placed at the bottom of a plug tray before seedling production, when the plug seedlings are ejected, pot bodies and roots of the plug seedlings can be protected, so that plug seedlings are vertical and seedlings can be rapidly ejected. The apparatus has simple structure and operation convenience, after the plug tray of the plug seedlings can be fixed to a correct position by the positioning pins, the pressing plate is placed over the plug seedling, the pressing plate external frame and an external edge of the plug tray are aligned, and at the same time damage on branches and leaves of the plug seedlings due to pressing can be avoided, the plug seedlings can be smoothly ejected by pressing the pressing plate, the ejected plug seedlings are kept vertical, so that the seedling picking shovel can be used for rapidly picking seedlings; seedling picking efficiency is greatly improved, pot soil and pot seedling roots of the plug seedlings can be protected, efficiency of transplanting work and survival rate of the plug seedlings are transplanting are improved, and soil environment is not polluted.

Description

technical field [0001] The invention is a simple and efficient plug-out seedling-picking device, which is mainly used in the seedling-picking operation of semi-automatic transplanting machines for vegetables, flowers, etc. The utility model relates to a device for ejecting seedlings from plug tray seedlings. The plug tray seedlings taken out are used for subsequent seedling separation and planting operations, and belong to the technical field of agricultural machinery. Background technique [0002] The main advantages of plug seedling transplanting: shorten the growth cycle of vegetables, flowers, etc., facilitate the arrangement of stubble, improve land utilization rate; improve seedling rate and utilization rate, easy seedling selection and seedling operation; root system of plug seedlings after transplanting Developed, it can provide convenient conditions for follow-up management and other links, and save maintenance costs and resources. The production of vegetables and ...

AI Technical Summary

Problems solved by technology

The existing traditional manual method of picking seedlings has low efficiency, high seedling damage rate, high labor intensity for the operator, and is prone to operational fatigue and highly concentrated mental stress, which affects the quality of transplanting operations; the existing method does not require manual seedling feeding and transplanting The mechanical seedling picking device with a faster planting speed is not suitable for the actual transplanting of plug seedlings in my country because of its complex mechanism, high cost, and immature technology, and is not suitable for small and medium-sized users.

The invention patent for semi-automatic transplanting machine seedling picking device (application number 201710145112x) discloses a plug seedling ejection device, which includes a pressing plate and a base, which can obtain the effect of quick seedling picking, but it damages the pot body and cannot Ensure that all the plug seedlings are ejected. If the plug seedlings are under too much force, the ejector pin of the base will enter the pot body, damage the root system of the plug seedlings, and cause some plug seedlings to not be ejected, or cause higher lodging rate, which affects the efficiency of seedling picking and the survival rate of plug seedlings
