Description

Seedling transport and protection device for plug seedlings

technical field

The utility model relates to parts of a transplanting machine, in particular to a device for conveying and protecting seedlings which is especially suitable for plug seedlings.

Background technique

At present, the main seedling methods of rapeseed in my country include seedbed seedling, nutrient pot seedling and plug seedling. Seedbed seedling transplanting is relatively simple, and semi-automated transplanting machinery can be used for transplanting, but the slow seedling period is longer. Nutrient pot seedling is to sow seeds in a regular-shaped nutritional pot. When transplanting, the whole nutritional pot is taken out together. The root system of the seedlings is basically not damaged, and the seedlings are basically not slowed down after transplanting. It is suitable for transplanting with semi-automatic transplanting machines. . Plug seedling cultivation is a special way of growing seedlings in nutrient pots, and plug seedling cultivation is easy to carry out industrialized automatic seedling cultivation and can be carried out indoors. This kind of seedling cultivation method is suitable for semi-automatic transplanting.

Existing transplanting machines can generally be divided into clamp-type transplanting machines, chain clamp-type transplanting machines, hanging cup-type transplanting machines, winding disc-type transplanting machines, seedling-guiding tube-type transplanters according to the different structures of planting parts. Transplanting machines, etc. And among these existing transplanters, the seedling delivery mode that the transplanter that contains mechanical seedling delivery mainly uses comprises belt-type seedling delivery, conduit delivery seedling, disc type delivery seedling etc. Different crops have different transplanting requirements, and the characteristics of different types of transplanting machines are different, but generally speaking, the degree of mechanization and automation of existing transplanting machines is relatively low. Looking at various transplanting machines at home and abroad, dry land transplanting machines mainly use plug seedlings or pot seedlings for transplanting. When transplanting, the seedlings need to be taken out of the seedling pots, which may easily cause seedlings to fall off and damage the seedlings, and the uprightness is poor. And because the degree of automation is not high, it is generally the feeding of one person and one row of rice seedlings, and the speed of artificial feeding of seedlings is extremely limited. In this case, the work production efficiency is low, and the frequency of throwing bowls of the planting parts has become the bottleneck of improving the planting speed, and has also become a worldwide problem. my country began to develop transplanting machines in the 1960s. It was mainly used for corn, cotton and other crops in the early stage, and later developed into transplanting rapeseed. It started late and the technology development was more difficult. Zhejiang Sci-Tech University disclosed a vegetable transplanting device in 2008, which includes a pot seedling tray conveying part, a seedling separating mechanism and a seedling falling part. After the ejector rod ejects the pot seedlings, the pot seedlings slide down on the seedling guide pipe along the conus line tending to the conical top of the seedling guide pipe mouth. The efficiency of the two lines of work needs to be improved. Therefore, designing a new and efficient planting part has become the key point for the development of transplanting mechanization.
