Combined type seedling raising tray for bowl-blanket rice seedling transplanting machine

Abstract

The invention relates to a combined type seedling raising tray for a bowl-blanket rice seedling transplanting machine. The combined type seedling raising tray for the bowl-blanket rice seedling transplanting machine comprises a hard plastic seedling raising tray and a paper seedling tray, wherein the hard plastic seedling raising tray is a rectangular open box body formed by a tray bottom and a tray body; the tray body is uniformly equipped with retractable support lugs; the distances between the tray bottom and the retractable support lugs are equal; each retractable support lug comprises a support lug cap arranged at one end of a horizontal block and a clamping hook arranged at the other end of the horizontal block, the horizontal block is inserted into the tray body, the support lug cap is located outside the tray body, the clamping hook is located in the tray body, and the length of the horizontal block is larger than the thickness of the tray body; the paper seedling tray is a grid body formed by uniform arraying of paper slips and provided with open upper and lower sides, and is located on the retractable support lugs, and a bowl seedling root cavity is formed between the lower end surface of the paper seedling tray and the tray bottom of the hard plastic seedling raising tray. The paper seedling tray can be inserted into a field directly with bowl-blanket seedlings, the hard plastic seedling raising tray can be recycled, so that the production cost of rice seedling raising is reduced, and the combined type seedling raising tray is environment-friendly.

Description

1. Technical field: [0001] The invention relates to a rice mechanized seedling-raising tray for rice transplanting in agricultural production, in particular to a combined seedling-raising tray for a paddy bowl blanket seedling transplanting machine. 2. Background technology: [0002] The blanket-shaped seedling tray seriously damages the roots of the seedlings during the transplanting process, and has a long seedling slowing period and a long growth cycle. The pot seedlings grow in the hole pots and are separated from each other, so they cannot be used in conjunction with the rice transplanters widely used now. The conjoined pot seedling tray can cultivate a pot-shaped blanket seedling with the lower part of the root in a bowl shape and the upper part of the root connected to each other to form a blanket, which effectively solves the problem mentioned before. However, the soft plastic seedling trays imported from abroad are widely used at present, which are not only expensi...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a combined seedling-raising tray for rice bowl blanket seedling transplanting machine, which is used to solve the problem that the existing blanket-shaped seedling raising tray is expensive and inconvenient for storage and maintenance. Abandoned seedling trays will cause white pollution problems
