(54) DEVICE FOR TRIMMING THE REMAINS OF SUCHIEV ON TREE

one

BACKGROUND OF THE INVENTION The invention relates to devices for cutting off residues of branches on logs.

A milling debarking machine is known, consisting of a drive rotor CO mounted on it by working bodies in the form of face milling cutters 1. 1 This machine cannot be used for trimming branch residues on logs, since the end mills used in the machine for arguing do not cut branch residues height with more than the height of the tooth cutter during the forward movement of the log.

Closest to the proposed mechanism with chain saws, consisting of a stationary body with an internal gear, to the crown of which is attached a movable body of the cutting head of chain saws 2.

The drawback of the device is the low quality of cutting of the residues of the boughs, since the cutting body in the form of a saw bar cannot cut the knot on a plane when the saw bar rotates around the longitudinal axis of the log.

The purpose of the invention is to improve the quality of processing logs.

This goal is achieved by the fact that the housing of the bevel gear reducer is rigidly connected with the movable housing and the shaft of the driven gear of the bevel gear is equipped with bearings with a spring-loaded frame with a copier fixed on it and the mill drive shaft on which the flywheel is fixed to reduce the device's energy consumption.

FIG. 1 shows a diagram of the proposed device, front view; in fig. 2 - the same, top view, section.

The device comprises a fixed annular body 1 with internal gearing gear, inside which

15, a pinion gear 2 is mounted on the bearings, receiving rotation from the electric motor 3, and a spur gear 4 with external gearing.

The movable body 5, inside which the gear .6 of the drive of the cutting mechanism is mounted, is attached to the gear crown 4. The housing 7 of the gearbox of the comic transmission is rigidly connected with

25 with a movable housing 5 The drive bevel gear 8 is located on the same shaft with the gear drive drive gear 6.

30 10 and the copiers 11, inside of which is the shaft 12 of the drive of the milling cutter 13 with the flywheel 14, is fixed by means of bearings on the same shaft with the driven gear 15 of the bevel gear. The torque from the shaft of the driven bevel gear 15 is transmitted to the cutter drive shaft 12 by means of a chain transmission 16. The process of cutting off the remains of the boughs is carried out as follows. The feeding mechanism logs 17 into a hole in the stationary ring body 1, with the end part abuts the milling cutters 13, gradually and moves it until the appearance of the copiers 11 on the surface of the log. The springs 10 are compressed therewith. The motor 3 drives the driving gear 2 and the driven gear 4 with the movable body 5. The gear drive gear b is driven around the gear with internal gearing of the fixed body 1 and rotates the bevel gears 8 and 15. The rotation is transmitted to the chain gear 16, shaft 12 of the cutter drive and onto the milling cutter 13. The milling cutter with the spring-loaded frame 9 rotates the log around the longitudinal axis and cuts off the branch. After processing the entire log, the following is submitted and the process is repeated. The rigid attachment of the gearbox of the bevel gear to the movable body, the use of a spring-loaded frame that can be rotated relative to the driven gear wheel of the bevel gear ensure high quality of pruning residues on the logs. The use of the proposed device makes it possible to mechanize the time-consuming process of stripping residues of boughs, increases the production culture, reduces injuries during this operation. The invention of the device for cutting off the remnants of boughs on logs, including a stationary ring body with internal gear, working bodies in the form of cylindrical mills and a driven cylindrical gear with external gearing, to the gear ring of which is attached a movable body and a bevel gear reducer, which , in order to increase the quality of processing logs, the gearbox of the bevel gear unit is rigidly connected with the movable body, and on the shaft of the driven gear of the bevel gear with the aid of the lower arm The fins are mounted with a spring-loaded frame with a cam mounted on it and a mill drive shaft, on which the flywheel is fixed to reduce the power consumption of the device.
