Description

A cutting and milling type jujube tree trunk circumcision device

technical field

The invention relates to a bark circumcision device, in particular to a cutting and milling jujube trunk circumcision device.

Background technique

In order to improve the yield of jujube trees and the quality of jujube trees, within a certain period of time each year, fruit farmers need to perform ring cutting on the bottom of jujube tree trunks. Ring cutting can effectively prevent the downward transport of organic matter produced by photosynthesis of jujube trees, making more Nutrients are delivered to the jujube flower, making it form more jujube fruit. In the prior art, there are two ways for fruit growers to circumcise jujube trees. One is to use a sickle or some knives to perform pure manual circumcision. In this way, the circumcision efficiency is low and the labor intensity is high. The other is to use some rings to The cutting mechanical device is changed. The Chinese patent with the notification number CN205884082U discloses a fruit tree ring cutting machine. The ring cutting machine uses a toggle wheel to drive the whole device to rotate around the trunk. For ring cutting operations, although the above device reduces the labor intensity of the operation, so that the fruit grower does not need to rotate around the trunk, the quality of the ring cutting mouth cannot be guaranteed. During the dialing process of the toggle wheel, the entire device may be deflected, making the ring cutting mouth Misalignment occurs, and at the same time, the device cannot flexibly meet the width requirements of the circumcision.
