(54) MACHINE FOR TREATMENT OF CUTTED TREES

one

The invention relates to machines for processing cut trees and can be used in the timber and woodworking industry.

A known machine for processing cut trees, comprising a self-propelled chassis, on which technological equipment is installed, comprising a movable jib, a delimbing head, a pulling mechanism, a device for transverse cutting of wood, a receiving-sorting device and a receiving tray.

The purpose of the invention, expansion, technology. ical capabilities of the machine.

For this purpose, the receiving tray is mounted on a carriage, which is movably mounted in vertical guides fixed on the self-propelled chassis of the machine.

FIG. 1 shows a machine for processing cut trees, general view; in fig. 2 is a view along arrow A in FIG. one; on . 3 is a section along BB in FIG. 1.

The machine contains a self-propelled chassis 1, on which the technological equipment is installed. ted, containing the reception is overturning-.

Tray 2, viewing mirror 3, a device for transverse sawing of wood, manufactured in the form of a slab 4, dragging mechanism in the form of drive bridges 5, operator's cab 6, boom 7, on which the gripper 9 is mounted on the carriage 8, a conveyor for cleaning sawdust 11, a lifting-intake carriage 12 on which a tray 1 is installed, the guides 13 of the carriage 12 and the running wheels 14,,

The frame machine rests on ribs 14 with wheels, which roll on the rail in th way. The movement of the machine takes place with the help of a wheel rotation drive.

The boom 7 is hinged at one end with the aid of a hydro-cylinder and can be lowered and raised.

The carriage 8 with the gripper 9 is moved along the boom 7 by means of a cable drive from the winch. The locking head 1O consists of three knives, one on one and two side. The bottom knife is mounted on the frame of the machine and can be lifted with a spring. Side knives are made movable from the hydraulic cylinder. Dilution of current knives causing lowering of the lower knife by mm. P buhi 5 for feeding the trunk with the help of a hydraulic cylinder can grasp the trunk, or push it apart to pass the trunk butt R Buha have their own drive for rotation and, with a force, for feeding the whip and cutting off small branches. With a considerable dragging force, which is necessary when cutting: large branches, the carriage 8 with the gripper 9 is put into operation. The receiving tray 1 is pivotally fixed on the carriage 12 and can be turned with the help of a treadmill to the dump position .; The carriage 12 can move in a vertical plane in the guides 13, for this it is provided with rollers. The raising and lowering of the carriage 12 is performed by a hydraulic cylinder. The lengths of the assortments are measured using a movable stop mounted on the receiving tray 1. The receiving tray device allows the assortment to be lowered with a low-filled or empty drive and squeezed from a small height, which ensures the accuracy of stacking and drives. The correctness of placing the assortments on the torp is achieved by the fact that the machine moves along the track and the longitudinal movement of the assortments after cutting is not performed. Correct placement of assortments along the accumulator and elimination of their subsequent manual rolling is achieved by appropriate movement of the maschina along the track. For cleaning the waste, a special conveyor 11 is installed inside the machine, through which sawdust and cutting are transferred to the conveyor 5 for collecting waste (cut boughs and other waste go to the crusher and then removed for further disposal). The technological process of pruning cutting and sorting branches with the help of the described maschina is carried out as follows. On overpass 16, a reserve of trees is created, the operator lowers the boom, makes a grip on the tree, turns on the gripping clamp and raises the boom with the tree above the ramp. Next, the operator inserts the carriage drive and feeds the whip to the saw. Simultaneously with the movement of the whip, the operator switched on

| 60 | feels the mechanism of movement of the machine to the napeepiel in accordance with the first assortment planned for sawing; When the carriage with the knots' grapples of the carving head passes, a command is given to press the knives against the trunk, and after closing the knives, the further movement of the trunk is followed by cleaning it from the branches. After supplying the whip to the saw, a whip is clamped with booms, tacked, and an order is issued for sawing the assortment. Feed-whip on the length of the assortment is made using p boo. At considerable forces of reduction, the carriage with grippers is turned on. To do this, the carriage moves from p to the delimbing head, a whip is clamped, and a carriage with a whip moves to the side of the saw. With consistent sawing of identical assortments, the machine stands still. In the case when, after sawing off one assortment, it is necessary to cut the assortment of another type, simultaneously with the cutting, the machine is moved to the corresponding drive. Due to the movement along the track, it is possible to combine the operations of uncovering. ki, pruning and sorting. The assortments from the receiving tray 1 are dropped into the drives by tipping the tray with a hydraulic cylinder. At the same time, short litter types (with a length of less than 3 m) are dropped from the small height for an even stowage in the storage device, for which the carriage and the tray are lowered to a small height. Claims Machine for processing cut trees, including a self-propelled chassis / on which technological equipment is installed, containing a moving-jib boom, a delimbing head, a pulling mechanism, a device for cross-cutting of wood that, with a chain of technological expansion, the receiving tray is mounted on a carriage that is movably mounted in vertical guides, mounted on a self-propelled chassis us. -, u: 5 Fie.2 5 - 6 F (/.
