Description

Special pinching device of fruit tree

Technical Field

The utility model relates to the technology of medical equipment, specifically a special pinching device of fruit tree.

Background

Fruit tree pinching is a technical measure for removing part of the newly germinated young tip of a branch. Pinching can be performed in spring, summer and autumn. Because the tip of the new tip is tender, the tip is usually pinched and removed with the fingertips during the production. Fruit tree pinching is a very important technical link in fruit tree shaping and trimming, and pinching is time-consuming and labor-consuming due to the large pinching quantity and strong pinching repeatability, but pinching is also an essential technical step in the growth period of fruit trees. If the core is not picked up timely, tree shape disorder, poor light transmission, outward movement of fruit parts, reduction of commodity rate, reduction of economic yield and the like are caused. By pinching management, the tree structure can be stabilized, flower bud differentiation is promoted, the quality and the yield of fruits are remarkably improved, the incidence rate of plant diseases and insect pests is reduced, and the fruit bearing life of fruit trees is prolonged. Most fruit trees need pinching 2-6 times a year. At present, pinching is mainly performed by hands in production, then scissors are used for pruning, and tools such as lopping scissors are often used for pinching new and young fruit trees with high crown.

When the core is picked up by scissors or high-branch scissors, branches are easy to be dragged and stubborn in operation, and the efficiency is relatively low. For kiwi fruit trees with slightly high crowns, sweet cherries, oranges, grapes, passion fruits and other fruit trees, pinching can be finished only by means of auxiliary tools such as gardening ladders.

Pinching with fingers, because fingers are flexible relative to scissors, efficiency is also higher than using scissors, but pinching with fingers is relatively poor in durability, and pinching work of a large area can be completed only by workers with good physical strength and endurance, for a park with a large scale, pinching work needs a lot of manpower, and can ensure that established tasks can be completed rapidly in a key phenological period, and meanwhile, manual operation cost of workers can be obviously improved.
