Ordered seedling-ejection guiding device

Abstract

The present invention discloses an orderly seedling-throwing and seedling-guiding device. It includes the following components: an inverted conical seedling-guiding tube, left and right rope bars and left and right rubber baffle plates. Said invention also provides their connection mode and concrete action of the above-mentioned every component. Said invention also provides its operation method.

Description

technical field [0001] The invention relates to general agricultural machinery, in particular to an orderly seedling-throwing and seedling-guiding device of a motorized rice seedling-throwing machine. Background technique [0002] According to the rice motor-driven and orderly rice seedling throwing machines currently sold in the domestic market and related research literature, rice pot seedlings are raised in plastic seedling trays, and the methods for orderly separating rice pot seedlings from plastic trays mainly include ejection, Clamping type, vibrating type, air suction type, air blowing type, etc., the row of seedlings is mainly realized by letting the freely falling pot seedlings fall from the seedling guide tube into the soil, that is, the seedlings falling from a seedling guide tube form a row. But because the rice shoots that fall into the same seedling guide tube are not only the rice shoots falling on the same row, but also some seedlings with a certain distance...

AI Technical Summary

Problems solved by technology

But because the rice shoots that fall into the same seedling guide tube are not only the rice shoots falling on the same row, but also some seedlings with a certain distance in the same row, if the guideline of the seedling guide tube is not good, the rowability of the rice shoots will be poor, and there will be Because the seedlings on different rows interfere with each other when the seedling guide tube goes up and down, affecting the planting distance

Generally, the shape of the commonly used seedling guide tube is a round tube or a rectangular tube, neither of which has a special guiding effect on the rowability of the seedlings.

In addition, when the seedlings are thrown from the seedling throwing mechanism, they are often in a tilted state with their heads facing down. The seedlings will naturally turn to the state of the heels facing down, and a free fall height of 400mm to 600mm is generally required. In this way, the seedling guide tube must If there is enough height, it will undoubtedly increase the volume of the whole rice throwing machine
