Description

FORESTRY

Harvesting combines are known, including a self-propelled chassis on which the cutting and directional tree felling mechanisms are installed, a loading arm, a log drive and a delimbing device containing a sawing mechanism, alternate grippers and a delimbing working member of force cutting.

The purpose of the invention is to expand the technological capabilities of the combine, as well as to increase productivity and reduce its size.

This is achieved by the fact that the delimbing-chewing device with the loading lever and the log storage device are mounted on the brackets of the common support frame in the rear part of the combine behind the tree shearing mechanism. Moreover, the drive has a receiving frame with two pairs of racks placed on it, one of which is rigidly connected to the receiving frame and provided with a loading lever mechanism with a receiving part for logs installed below the level of the working organs of the delimbing-chewing device, and the other is associated with the receiving frame is articulated with the possibility of tilting when unloading the storage device. The receiving frame of the latter is rotatable in a vertical plane relative to the common support frame and displaced in the transverse direction relative to the longitudinal axis of the self-propelled chassis by an amount that fits the delimbing-opening chewing device and the loading lever mechanism of the accumulator into the transverse envelope of the combine determined by the rest of the process equipment. The loading lever mechanism accumulator is made in the form of fixed on the tops of its fixed side racks

paired L-shaped levers, actuated by a hydraulic cylinder, hinged on the receiving frame of the drive. In order to convert a combine to another technological scheme of logging, for example,

For skid-free skidding of trees behind a joint, the common support frame is made removable. And the latter is made with a telescopic beam pivotally connected to it, on one part of which a saw is mounted

a mechanism and a device for fastening a tree, and on the other, a delimbing working tool for power cutting with knives.

FIG. 1 shows the proposed combine, a general view; in fig. 2 - log drive with

loading lever mechanism and removable support frame.

A self-propelled chassis / logging combine, for example a crawler, mounted 2 cutting mechanisms and 3 snow tracks near a tree to be cut and a detachable common support frame 5, on the brackets 6 of which, in turn, were mounted a loading arm 7, a delimbing device 8 and a storage device 9 logs. The loading lever is mounted on the axis 10 and the action of the hydraulic cylinder // is driven by B.

The delimbing-chewing device contains a beam 12, hinged using axis 13 on the support frame 5. Inside the beam 12, a telescopic beam 14 is movably axially mounted. Beam 12 has a saw mechanism 15 and grippers 16 alternately acting, and at the end of the beam 14 - power cutting delimbing tool 17, the knives of which at a certain moment perform the role of gripping.

The log end 9 has an acceptor frame 18, on the sides of which twin racks 19 and 20 are installed. The left (along the combine) pair of racks 19 is rigidly connected to the receiving frame 18, and the right is fixed on it pivotally by means of axis 21 and in transport position In a known manner, it is locked with a lock (in the FNG. Not shown).

Makoligel 9 is equipped with a loading-lever mechanism 22, made in the form of sparse 1-arm, pivotally with iiOMOuiH axis 23 fixed on the vertex i; acTi non-movable racks 19 and driven by the hydraulic cylinder 24.

The receiving frame 18 is hinged on the smallpox 25 secured with a bracket 6 and unrn unloading by the pack; The gel is activated by a HP cylinder 26.

The logging machine works in the following way.

Moving along the edge of the forest, the harvester stops near the tree to be cut. In this case, the operator preliminarily fixes the mechanism of 2 cutting with respect to the tree. (In winter, snow clearing of the tree being cut is performed by device 4). Then, he pushes the mechanism of the 3th folded trees and imitates them. After lowering the loading lever 7 proceeds to the city of Yleshpo wood. At the end of the pileny, the mechanism 3 is automatically switched on and, under its effort, the tree hits the loading lever. Then, the mechanisms 3 and 2 are set to their original position, and the butt of the tree is loaded with the loading lever into the delimbing device 5. At the same time, the butt of the tree is laid into the U-shaped bases of the grippers 16 of alternate action and the delimbing working body 17 of the force cutting. By hinging, the beam 12, under the weight of the tree, takes such a position that its longitudinal axis becomes parallel to the axis of the tree. Further, the tree is clamped by the grippers 16, the delimbing working body 17 is lowered, and the beam 14 is advanced, carrying the working body 17.

while the tree gripped by the grippers 16 remains stationary.

Then, the tree by the working body 17, which at the end of the pruning of the branches has the role of seizing, is ejected, and the grippers 16 of the alternate action are opened. After pruning -beams on the required length of the tree, the operator includes a nil mechanism 15, at the withdrawal of which, but ending

The delimbing working body 17 is automatically retracted to the initial position.

The postponed assortment is applied to the receiving arms of the loading device, after which the branches pruning and cutting the remaining parts of the tree are repeated.

At the end of wood processing, the assortments lying on the L-shaped levers of the loading-and-lever mechanism are not unloaded by the inclusion of the gyroscopic 24 in the drive

9, and the harvester moves to the next tree, the store loaded with assortments is unloaded either at the cutting area or at the ramp-level platform along the forest road by opening racks 20 on the turn frame of the receiving frame 18 with hydrocyldrams 26. Pa fng. 2 shows one of the options for unloading -connector 9.

The combine can overload a pack of assortments directly from the hopper to previously prepared trailers.
