Description

one

This invention relates to logging machines and may be used in the forest industry.

The known machine for cutting branches from felled trees, includes, and the self-propelled chassis, which is installed with help, and the boom supported by the boom, equipped with a retractable beam, gripping-cutting, their device and device for longitudinal smashing, tree, mounted on the extendable boom beam with help and mobile carriage in the form of two rows of turn rolls.

The disadvantage of this machine is the difficulty of capturing the beds, in packs of trees, to be processed.

Also known machine for processing fallen trees, including 10, and self-propelled chassis with technological equipment, contains a rotary column with hinged on it and directing it, its support, with help, and which is mounted on the column retractable beam with reinforced at its end rezush, bodies , and the drive cutting organs 2J.

The disadvantage of this machine is the complexity of the design.

The aim of the invention is to increase efficiency.

This is achieved by the fact that the drive of the cutting system, their organs is made in the form of two connected hydraulic cylinders; it has a device for creating in one of them an overpressure in the form of an elastic body connected to the stem of the flexible body, the other end of which is fixed on the opposite side rezhush, to them the organs of the end of the retractable beam, and on iairavl yush, her support was set by two trees, a flexible organ was propped up through the cockroach, and one of the blocks was made adjustable from the hydraulic cylinder, which was hinged a guide bearing, an effort to provide noobhodpmyh prpzhima cutting bodies last cylinders with different diameters are made.

Ma FIG. i shows a machine for processing fallen trees, rear view; on (rig. 2 - guide and pull out an oalka with cutting organs, BJU juice; on phg. 3 - section A-A in Fig. 2; Fig. 1 is a schematic diagram of the hydraulic drive of the cutting bodies.

The machine consists of a self-propelled driver 1, on which a rotary column 2 is mounted, on the upper end of which a guide support 3 is hinged. During the operation, the position of the guide support relative to the tractor can be replaced

horizontal and anravleiin due to the column iioiiopot around the vertical axis and in the vertical direction by turning around axis 4 with the help of hydraulic cylinder 5. At the guide of the pasMenteHO, a receiving-holding device (5 and a torsional device consisting of a hydraulic cylinder 7, at the end of the rod of which is reinforced block 8, and a bracket with a cable end block 9. A retractable beam 10 passes through a guide support, at the end of which a cutting head is fixed, having cutting bodies II consisting of a body and three knives q ue opening which osup1, est1, .ch (ggsi gidrotsiliidrom 12.

To create the necessary pressure of the working fluid on the hydraulic head in Hydronilpidra 12, a hydroniliidre 13 is strengthened, the rod cavity of which is filled with the working fluid and connected by means of a pipeline 14 to the piston cavity of the hydraulic tools 12 controlling the cutting bodies. The spiral springs 15 serve to return the hydrocyliidry 12 and 13 to their initial position. From the hydraulic cylinder rod 13, a flexible body 16 extends along the telescopic beam, which bends around blocks 8 and 9 strengthened with guide support 3 and fixed to the end through the lanyard 17 retractable beam. Lanyard 17 serves to pre-tension a flexible organ.

The work of the maschina is carried out as follows.

To close the cutting bodies, the operator turns on the spool, through which the pressurized fluid flows through the pipeline into the hydraulic cylinder 7 cavity. When the hydraulic cylinder 7 moves, the flexible body envelopes the block 8, which bends around the rod 8. The force that occurs in the flexible body is transmitted to the hydraulic cylinder rod 13, in which an overpressure is created, in connection with which the working fluid rushes into the piston cavity of the hydraulic cylinder 12, during the movement of the rod of which the cutting bodies close.

The pressure of the cutting bodies against the stem to be machined will be the greater, the more flexible the tension is.

In addition, the design allows the pressure in the hydraulic cylinders 12 and 13 to be repulsed due to the calculation and selection of their diameters, which will allow an increase in the processing quality.

Claims (2)

1. A machine for treating povalepnyh trees, including self-propelled vehicles with technical equipment, containing a rotary column with an articulated paired guide support, with which the column is installed on the end of the beam cutting bodies, and cutting bodies drive, characterized in that, in order to increase its efficiency, the cutting bodies drive is made in the form of two hydraulic cylinders interconnected by pipeline and has an arrangement for creating in one of their overpressure in the form of a joint The hydraulic cylinder of a flexible organ, the second end of which is fixed on the end of the retractable beam opposite to the cutting organs, and on the nanoway of a young support there are two blocks through which the flexible organ passes, one of which is s is adjustable by gidrotsiliidra pivotally mounted pas guide support. 2. The machine according to claim 1, characterized in that, in order to provide the necessary forces for pressing the cutting bodies, the hydraulic cylinders of their drive are made with different diameters.
