Fruit tree pruning device

Abstract

The invention relates to the technical field of pruning devices, in particular to a fruit tree pruning device. The fruit tree pruning device comprises a movable base, a height and angle adjusting device, a pruning transmission device and a pruning knife, wherein the pruning transmission device comprises a transmission box, a worm gear, a knife frame, a knife shaft, a connecting rod, a spring, a sliding push plate, a sliding block, a second motor and a reciprocating lead screw, the right end of the transmission box is fixedly connected with the worm gear, the left end of the transmission box is fixedly connected with the knife frame, the inner side of the worm gear is fixedly connected with the knife shaft, the outer side of the knife shaft is rotationally connected with the pruning knife, the right end of the pruning knife is rotationally connected with the connecting rod through hinges, and the right end of the connecting rod is rotationally connected with the sliding push plate. According to the fruit tree pruning device, through the arranged pruning transmission device, the sliding push plate slides in the transmission box in a reciprocating mode, so that the connecting rod drives the pruning knife to be opened and closed, automatic pruning of fruit trees is achieved, manpower is saved, and the pruning effect of the fruit trees is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pruning devices, in particular to a pruning device for fruit trees. Background technique [0002] Fruit trees refer to trees with edible fruits, a general term for perennial plants and rootstocks that can provide edible fruits and seeds, such as apple trees, pear trees, citrus trees, apricot trees, peach trees, etc. During the growth of fruit trees, In order to ensure early fruiting, high yield, stable yield and high quality of fruit trees, the fruit trees need to be pruned. Therefore, the demand for a kind of fruit tree pruning device is increasing day by day. [0003] Existing fruit tree pruning is generally carried out manually by workers holding pruning tools, which is labor-intensive. Because it is difficult to adjust the height and pruning angle of the pruning tool, the pruning efficiency is low, and the pruning force of the tool cannot be adjusted during the pruning process. Effective control lead...

[0003] Existing fruit tree pruning is generally carried out manually by workers holding pruning tools, which is labor-intensive. Because it is difficult to adjust the height and pruning angle of the pruning tool, the pruning efficiency is low, and the pruning force of the tool cannot be adjusted during the pruning process. Effective control leads to uneven cutting effect, therefore, a kind of fruit tree pruning device is proposed for the above problems
