Description

The invention relates to the forest industry, in particular to forest machines, and can be used for trimming knots from trees and pulling for subsequent bucking of whips into assortments.

A well-known multi-saw bucking machine (RU 2255855 according to class B27B 31/00, 29/00, 5/00 dated 05/12/04). It includes a trestle with means of supplying wood raw materials, a saw unit, a roller table, transverse dumping conveyors, loggers for sorted timber and a waste conveyor. As a means of supplying wood raw materials, a universal manipulator for wood raw materials was used, in which the rotary beam with equipment is mounted on a hydraulic lift with the possibility of changing its height relative to the surface of the earth. Both ends of the swivel beam of the hydraulic manipulator are equipped with retractable telescopes, and the gripping-cutting device is made of two gripping-cutting heads mounted at the ends of these telescopes. And the saw unit is made in the form of pendulum saw blocks installed alternately left and right execution.

However, this bucking plant does not provide for a clear sorting of assortments, for example, by diameter.

According to patent RU 2312009, cl. B27B 5/00 of 03/23/06 is known for a multi-sawing unit, which includes a flyover with a means of supplying wood raw materials, a saw unit in the form of pendulum saw blocks, a roller conveyor, transverse dumping conveyors, loggers for logs, universal manipulators for wood raw materials and a conveyor waste. The unit is equipped with a second live roll, the saw unit is installed in the area of the universal manipulators for wood raw materials with the possibility of individual bucking of whips from two live rolls adjacent to one flyover. Universal manipulators are made interchangeable with the possibility of measuring the geometrical parameters of the whip and the purpose of the program for cutting it and are equipped with delimbing heads. The rollers are made with the possibility of additional orientation of the whip and removal of substandard whip. The unit is equipped with two longitudinal conveyors for removing substandard whips installed behind the roller tables.

The disadvantage of this installation is the lack of sorting of cut logs by diameter.

Known universal manipulator for wood raw materials (RU 2299119, class B27B 27/00 of 02.16.2004). It contains a swivel beam, on which a pulling mechanism is mounted, made in the form of a carriage mounted in the guides of the beam with controlled grippers, a gripping-cutting device, and a pump station with control cylinders. A swing beam with equipment is mounted on a hydraulic lift with the possibility of changing its height relative to the surface of the earth. Both ends of the swing beam are equipped with telescoping telescopes, and the gripping-cutting device is made of two gripping-cutting heads mounted on the ends of these telescopes.

The objective of the invention is to increase productivity by simplifying and improving the design of equipment.

The technical result achieved using the invention is to reduce the time for sorting razrezhennyh assortments, to increase the mobility of the manipulator for wood raw materials and reduce conveyors.

The specified technical result is achieved by the fact that in a mechanized system of transverse cutting of tree trunks, including a receiving trestle, sawing units, live rolls, transverse and remote conveyors, and a universal manipulator with a swing beam located on the hydraulic lift, on which a pulling mechanism is mounted, a gripping-cutting device made of two heads mounted at the ends of the telescopes, and the hydraulic jack is mounted pivotally with the possibility of rotation with the help of a hydraulic cylinder in the longitudinal direction iyam rotatable beam hydrolift made further turning in the horizontal plane around its vertical axis by fitting it with a hinge and a hydraulic cylinder on a common turntable, a movable, e.g., from an additional hydraulic cylinder to the stationary base. In the second version, in a mechanized system for the transverse cutting of tree trunks, including a receiving rack, a universal hydraulic manipulator for wood raw materials with a hydraulic lift on a common rotary platform, balancing saw units, a roller table and forest storages, the roller table is additionally equipped with double-sided sorters directly to the forest storages, made with the possibility of storage in three zones, the first of which includes assortments with diameters from 38 cm and above, the second from 28 to 38 cm, the third - from 18 to 28 cm.

Figure 1 shows a mechanized system for the transverse cutting of tree trunks on the basis of a universal hydraulic manipulator with transverse and longitudinal conveyors for sorting assortments. Figure 2 shows an improved hydraulic manipulator, figure 3 is an example of a rotation mechanism of a common platform. Figure 4 shows a mechanized system for the transverse cutting of tree trunks on the basis of a universal hydraulic manipulator with forest accumulators without transverse and longitudinal conveyors.

The mechanized system for the transverse cutting of tree trunks consists of a hydraulic manipulator 1, a flyover 2 with a puller 3, saw units 4, transverse conveyors 5, a rolling table 6 and external conveyors 7 and 8. The manipulator 1 includes a hydraulic lift 9 with a swivel beam 10 on which pulling mechanisms are mounted 11 and 12 with gripping-cutting heads 13 and 14. A certain mobility of the beam 10 is provided by the hydraulic cylinders 15 and 16. And the rotation in the horizontal plane around the vertical axis of the hydraulic lift 9 is carried out, for example, an additional hydraulic cylinder 17, which rotates on a stationary base 18 a common rotary platform 19, on which the articulated hydraulic jack 9 is mounted together with the hydraulic cylinder 16 (Fig.3).

In the second embodiment, the mechanized system for the transverse cutting of tree trunks consists of a hydraulic manipulator 1, a flyover 2 with a spreader 3, sawing units 20 of the balancer type, a rolling table 21 with two-sided ejectors 22, and forest collectors 23.

In the first embodiment, the system operates as follows.

On trestle 2, from a package of trees or whips with the help of a pulling device 3, a tree or a whip is fed into the coverage area of the universal manipulator 1. Using a swivel beam 10, controlled by a hydraulic lift 9 and hydraulic cylinders 15, 16 and 17, the butt of a tree or a whip is caught by a pulling mechanism 11 s gripping-cutting heads 13 and 14 and pulled to the mechanism 12. The pulling tree trunk is oriented along the saw units 4 using an automatic device that determines the size by which start of the cross cutting program. Then the manipulator 1 lays the barrel on the roller table 6, designed to adjust the length of the peeling. After orientation, a bucking command is issued, which is carried out by simultaneously pushing the whip onto the saw units 4 with transverse conveyors 5, on one or the other side of the roller table 6. After sawing, the assortments are fed to the outboard longitudinal conveyors 7 and 8 with the subsequent removal of the assortments in one or another direction. The installation of the articulated hydraulic jack 9 with the hydraulic cylinder 16 on the rotary platform 19 with the possibility of mobility around its vertical axis relative to the stationary base 18 using the hydraulic cylinder 17 increases the maneuverability of the manipulator 1 and simplifies the operation of the entire system.

According to the second embodiment, the mechanized system of transverse cutting of tree trunks works as follows.

As in the first embodiment, with the manipulator 1, wood raw materials from the overpass 2, disconnected by the device 3, are individually oriented according to the saw units 20 of the balancer type. The next tree trunk is laid on a roller table 21 with ejectors 22. The trunk is oriented from its diameter into three zones: from 38 cm and above, from 28 to 38 cm, from 18 to 28 cm. Sawed logs are dumped into forest storages 23 as on one side of the roller table 21 both ways.

The absence of transverse conveyors for the removal of assortments greatly increases the productivity of the process of transverse cutting of tree trunks. And sorting assortments into three zones with the same diameters by forest collectors makes it possible to efficiently produce and use forest products.
