Seedling falling control mechanism of potted seedling transplanting machine

Abstract

The invention relates to a seedling falling control mechanism of a potted seedling transplanting machine and belongs to the technical field of agricultural machinery. The seedling falling control mechanism comprises a front opening and closing plate, a rear opening and closing plate and a seedling falling frame; the front opening and closing plate and the rear opening and closing plate are arranged at an output end of a seedling conveying barrel base plate and comprise a folded horizontal plane respectively; the seedling falling frame extends upward from the front end of the seedling conveying barrel base plate; the upper portion of the outer side of the front opening and closing plate and the upper portion of the outer side of the rear opening and closing plate and the middle of an inverted V-shaped lever piece and the middle of a straight lever piece are supported on a fixing plate through a horizontal pin shaft in a hinged mode respectively, wherein the fixing plate is arranged at the front end of the seedling conveying barrel base plate; the lower portion of the folded horizontal plane of the front opening and closing plate is hinged to the inner lower end of the inverted V-shaped lever piece and the lower portion of the folded horizontal plane of the rear opening and closing plate is hinged to the lower end of the straight lever piece; the upper end of the straight lever piece and the inner lower end of the inverted V-shaped lever piece are hinged to two ends of a connecting rod respectively; the upper portion of the seedling falling frame is hinged to a cylinder body of a cylinder; the lower end of a piston rod of the cylinder, which extends downward, is hinged to an outer lower end of the inverted V-shaped lever piece. According to the seedling falling control mechanism of the potted seedling transplanting machine, the accurate control on the seedling falling time of potted seedlings can be facilitated and meanwhile a seedling falling opening is gradually opened, the opening speed can be convenient to control, and accordingly the potted seedlings can reliably fall down and the seedling injury rate and the seedling fall rate are significantly reduced.

Description

technical field [0001] The invention relates to a device on a transplanting machine, in particular to a seedling drop control mechanism of a pot seedling transplanting machine, which belongs to the technical field of agricultural machinery. Background technique [0002] Crop transplanting is conducive to greatly increasing grain yield per unit area, improving land utilization rate, and improving seedling quality, and has many advantages. [0003] According to the applicant's understanding, the current crop transplanting mainly relies on semi-automatic transplanting machines, which need to manually complete the seedling picking, and then manually place the seedlings in the pot on the rotary seedling transporting mechanism (such as clamp type, chain clamp type). Afterwards, when the seedlings in the pot move to the top of the planter along with the seedling transfer mechanism, the seedlings are directly dropped and planted. Although this type of existing transplanting machine...

AI Technical Summary

Problems solved by technology

Although this type of existing transplanting machine has a simple structure and is easy to operate, the transplanting effect is poor, the rate of injured seedlings and seedlings is high, and the uniformity of transplanting pot seedlings is low, and the ability to actively control the process of pot seedling transportation Difference
