Angle-adjustable type agricultural tree trimming device

Abstract

The invention discloses an angle-adjustable type agricultural tree trimming device in the technical field of agriculture. The trimming device comprises a supporting frame body. A handheld handle is installed at one end of one side wall of the supporting frame body. An installing groove is formed in the other end of one side wall of the supporting frame body. A rotating shaft is rotationally inserted in the installing groove. A hydraulic cylinder is installed at the bottom of an inner cavity of the installing groove. The rotating shaft is sleeved with a sleeve. The two side walls of the sleeveare provided with a lower turning plate and an upper turning plate respectively. The outer wall of the sleeve is provided with a fixing hole. The sleeve is fixedly connected with the rotating shaft through the fixing hole. The outer wall of the lower turning plate and the outer wall of the upper turning plate are each provided with a spring gasket. A buffering spring is installed in each spring gasket. The trimming angle of a trimming saw web is realized, the trimming efficiency is greatly improved, operation is simple and rapid, structure installation is stable, labor intensity is greatly reduced, and more time and labor are saved during agricultural tree trimming.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an angle-adjustable pruning device for agricultural trees. Background technique [0002] A tree is a plant represented by "branches" and "stalks" and "leaves" that can live for decades. Arbors are generally referred to as trees, with a distinct upright trunk, generally tall plants, and branches that are higher from the ground to form a canopy. There are many kinds of trees, and in the common saying, relatively large shrubs are called "trees", such as pomegranate trees and tea trees. Trees are the general term for woody plants, which can be divided into trees, shrubs and woody vines. Trees are mainly seed plants. Among ferns, only tree ferns are trees. There are about 8,000 species of trees in China. [0003] At present, the Chinese patent with the notification number CN201595032U discloses a multipurpose tool for tree pruning, which includes a lower rod body, an intermedi...

Problems solved by technology

[0003] At present, the Chinese patent with the notification number CN201595032U discloses a multipurpose tool for tree pruning, which includes a lower rod body, an intermediate rod body is installed on the upper end of the lower rod body through a connecting hoop, and a tool head is fixed on the upper end of the middle rod body. It is more convenient to carry and use, but when this tree pruning multi-purpose tool is in use, the positions of the lower rod body, the middle rod body, and the tool head are fixed, so that when the trees are trimmed, the lower rod body and the middle rod body are always on the same straight line, When it is necessary to trim the tree into a certain shape, as the angle of the tree’s shape changes, it is necessary to constantly adjust the position between the user and the tree, so that the angle formed between the tree pruning multitool and the ground is the same as the angle between the tree’s shape and the ground. The angle between them is the same, so that the trees can be pruned into shape, but it takes more time and reduces the work efficiency to a certain extent
