(54) DEVICE FOR TRIMMING THE CROWN OF TREES

one

: The invention relates to a separate machinery industry, in particular to devices for trimming tree crowns.

It is known a device for contour cutting of fruit trees, made in it, s de bruce, on which several circular saws are mounted frontally with the drive mechanism 1. The device is installed: on a suspension frame and with the help of a hydrocyle core can take a horizontal, vertical and inclined position .one

Such a device produces a continuous j pruning of the upper part of the tree crown, as a result of which a significant part of the fruitful twigs and shoots are removed, which leads to a decrease in the yield of fruit trees.

It is also known a device for trimming the crown of trees, comprising a lifting platform mounted 20 on a vehicle with a undercutting mechanism mounted on it in the form of a rod, one end of which carries the cutting apparatus and the other is equipped with a control system 2 .25

This device is the closest to the invention in terms of technical drying and the result achieved.

The disadvantage of the device is that, in connection with a large rod length, pa-j is unable to hold the tool for cutting branches located in the price of the crowns of the tree.

: In order to increase the maneuverability of the sub-. of the device, the lifting platform of the proposed device is equipped with a hinge {- but mounted on it by one end of the carrier, carrying on the other end of the slide, to which the middle part by means of horizontal | ; zonal hinge attached rod.

FIG. 1 shows a device for trimming tree crowns, side view; in fig. 2 - the same, top view; on f1ig. 3 knots of a bar suspension.

The device consists of a rod 1, at one end of which a hydraulic motor is mounted 2. A cutting device 3 is installed at the output of the hydraulic motor, locked with a casing 4. The hydraulic motor 2 is rigidly attached to the housing of the hydraulic engine 2 84
