Rotary oscillation seedling transplanting device of dry filed plug seedling transplanter

Abstract

The invention relates to a seedling transplanting device of a dry filed plug seedling transplanter. The seedling transplanting device is characterized by comprising an oscillating bar cam mechanism, a planet gear mechanism, a chain transmission mechanism, a full line seedling picking device, a plug tray, a rotary support cup and a frame, wherein an oscillating bar is idly sleeved on a driving shaft and is driven by a cam I, and the oscillating bar is driven by the cam I to carry out periodic oscillation including stopping, 90-degree forward rotation, stopping and 90-degree inverse rotation; the planet gear mechanism is driven by a gear II to drive the chain transmission mechanism, and a chain transmits and drives a cam shaft II to rotate circularly; two vertical slide bars are installed in an oscillating bar sliding sleeve and are connected to a seedling picking support, and the full line seedling picking device can move up and down in the oscillating bar sliding sleeve through the two vertical slide bars; and by virtue of contact between a cam II on a cam shaft II and an oscillating bar top block, the full line seedling picking device is controlled to move according to a movement rule of descending for seedling picking, stopping without movement, lifting for seedling taking, lifting stopping, 90-degree forward rotation along with the oscillating bar and 90-degree inverse rotation. The seedling transplanting device has relatively simple structure and can effectively realize seedling picking automation.

Description

technical field [0001] The invention belongs to a dry land transplanting machine, in particular to a seedling transplanting device capable of taking out the entire row of seedlings in the plug tray at the same time and transferring the whole row to the rotating support cup of the transplanting machine. The device can be used to realize the transplanting of seedlings in the dry land plug tray The transplanting machine takes the seedlings and puts the seedlings in the whole row. Background technique [0002] The seedling taking and transplanting device is an important part of the dryland transplanting machine, and it is a key component to distinguish between a fully automatic transplanting machine and a semi-automatic transplanting machine. Among the existing dryland transplanting machines, the semi-automatic transplanting machine has a simple structure and relatively mature technology, so it is widely used. However, the semi-automatic transplanting machine needs to manually ...

AI Technical Summary

Problems solved by technology

At present, a kind of semi-automatic transplanting machine with rotating support cup has been widely used, such as Jingguan PVHR2 type dry land transplanting machine, its working principle is to set a circle of rotating support cup above the transplanting machine planter, manually Feed the pot seedlings into the cup, rotate the cup to a specific position, open the bottom plate of the cup, and feed the pot seedlings into two or more planters in turn. This kind of transplanter has high planting efficiency, but the disadvantage is that it requires manual labor. Feeding seedlings
