A device and method for automatically sending seedlings, taking seedlings, and throwing seedlings for a plug-in seedling transplanting machine

Abstract

The invention belongs to the technical field of agricultural mechanized transplanting, and particularly relates to an automatic seedling feeding, taking and dropping device and method of a plug seedling transplanting machine. The device comprises a frame, a seedling feeding mechanism and a seedling taking and dropping mechanism, and the seedling feeding mechanism comprises a screw driving motor, achain driving motor, a sliding rail, a side plate, a vibration plate, a chain, a seedling tray bottom plate, a driven shaft, a driving shaft, a rear slider bracket, a slide rail slider, a first connecting frame, a ball screw, a screw slider, a second connecting frame, a third connecting frame and a front slider bracket; the seedling taking and dropping mechanism comprises a supporting vertical plate, a seedling guiding tube support, an air blowing tube holder, an air blowing tube and a seedling guide tube. According to the invention, pot seedlings are separated from a seedling tray through vibration, and then are taken out from the bottom of the seedling tray and directly planted, so that the processes of taking and dropping seedlings are combined, the efficiency is higher, a pot seedlingsubstrate can be effectively prevented from being broken, root injury and other conditions are avoided, and the survival rate of transplanted pot seedlings is enhanced greatly.

Description

technical field [0001] The invention belongs to the technical field of agricultural mechanized transplanting, and in particular relates to a device and method for automatically sending seedlings, picking seedlings, and throwing seedlings for a plug-in tray seedling transplanting machine. Background technique [0002] Vegetable transplanting, at present, basically adopts seedling transplanting technology, which can make full use of light and heat resources, improve the multiple cropping index of crops, and has the comprehensive benefits of compensating for climate and advancing the growth period of crops. Seedling cultivation and transplanting technology can raise seedlings in advance in protected areas, shorten the growing period of crops in the field, improve land utilization rate or prolong fruit harvesting period, thereby increasing the multiple cropping index and yield per unit area. Seedling raising and transplanting technology can also establish the early advantages of...

Problems solved by technology

However, the current transplanting technology in our country is still dominated by semi-automatic transplanting. In the transplanting operation, the seedlings are taken out manually, and then the seedlings taken out are fed to the corresponding conveying device or directly into the planting device. Due to the limited speed of manual seedling feeding , the number of operation and follow-up assistants is large, the transplanting efficiency is not high, and the benefit of mechanization is not obvious
