Description

Pruning scissors for fruit and vegetable seedling grafting

Technical Field

The invention relates to the technical field of agricultural mechanical equipment, in particular to a pruning shear for fruit and vegetable seedling grafting.

Background

The main reasons for grafting vegetables at the seedling stage are as follows: by means of strong stress resistance, growth potential, disease resistance and the like of root systems of the stocks, the disease attack of vegetables is reduced, the growth potential is enhanced, the stress resistance is improved, and the like, and the aims of continuous cropping, yield increase, income increase and the like are fulfilled; when the plant is grafted, the more tender and tender the tissue of the joint part is, the more vigorous the meristem is, the more easily callus is formed after grafting, and the more easily the joint of the scion and the stock is jointed to survive; the survival rate of the grafted seedlings is improved; the method is favorable for obtaining high-yield vegetables, and at present, the roots of seedlings need to be cut off firstly during grafting, and then the wounds are trimmed into corresponding shapes according to a grafting method. The existing pruning shears for fruit and vegetable seedling grafting are mostly similar to common shears, when roots are removed, the seedlings need to be held by one hand, the shears need to be controlled by the other hand, the manual strength is high, only a small number of seedlings can be pruned, the time of the whole pruning process is prolonged, and the pruning efficiency is low.

Chinese patent No. CN 201820276626.9's a vegetables grafting is cut, including non-slip rubber, press handle, interior sword, vice cutter, sword shell, main cutter, set screw, hole pressing sword, briquetting, hook type piece, return hinge block, fixed valve block, interior sword is located return hinge block, the main cutter embedding is installed in the sword shell, set screw and sword shell threaded connection, hole pressing sword embedding is installed in the sword shell, the briquetting welds with hook type piece, hook type piece is located the below of hole pressing sword, the utility model relates to a vegetables grafting is cut, the slip ring in the return hinge block of its sword shell left side and ball mutually support, the spring on its spring connecting block exerts the spring force to press handle connector mutually, makes press handle reset, through the structure of improvement return hinge block, makes it pass through ball cooperation, reduces the coefficient of friction of its handle, again makes the correction of returning to press handle by its spring, make the equipment use convenient more durable, but the utility model discloses the vegetables kind that is suitable for has received certain restriction, also can only carry out the lopping to a small amount of seedlings, has prolonged the time of whole lopping process, and lopping efficiency is lower.
