Abstract

FIELD: forest industry, in particular, bunch gathering and transporting machines.

SUBSTANCE: logging machine has self-propelled chassis on which chassis process equipment is mounted, said equipment comprising winch with load cable, boom, grip mounted at free end of boom and equipped with drive and deflecting block for load cable, and device for holding of bunch on self-propelled chassis during transportation thereof. Boom is mounted on self-propelled chassis for rotation around vertical axis by means of rotation mechanism. Winch is positioned so as to be moved from self-propelled chassis and positioned on ground during yarding by means of, for example, rotation levers. Said levers are pivotally fixed with their one ends on self-propelled chassis and are pivotally connected with their other ends to winch drum shaft. Levers are rotated by means of power hydraulic cylinders. Longitudinal axis of winch is extending in parallel with longitudinal axis of self-propelled chassis.

Description

The invention relates to machines for collecting bundles of trees (whips) and their transportation and can be used in the forest industry and forestry.

A well-known forestry machine, including a self-propelled chassis, on which an arch with a drive is mounted, on the upper end of which a boom-beam with a drive is pivotally mounted, a tick-borne tongue grip is installed on the rear free end of the boom, and a winch installed between the arch and the cabin, with one end the cable is mounted on the winch drum, and the other is passed through the block and connected to a pack of tick-borne grippers (Prospect of the International Exhibition LESDREVMASH-79, exposition of the USSR, skidders: USSR. - M.: Sokolniki. August 29-August 12 September 1979, Vneshtorgizdat.Pub. No. 78 - p, 1979, Forestry Wheel Tractor ML-18).

The well-known forestry machine can be used only for skidding formed bundles, the machine should be suitable for each bundle, which increases the likelihood of damage to the soil cover, undergrowth and root system of the remaining growing trees, which is not desirable for gradual, selective felling and thinning.

A forestry machine is also known, including a self-propelled chassis, on which technological equipment is mounted, containing a winch with a freight cable, an arrow, on its free end a grip with a drive and a deflecting unit for a freight cable is mounted, and a device for holding the transported bundle on the machine (RF Patent No. 2224417, Cl. A 01 G 23/02, 02/27/2004).

However, in the known logging machine, the boom with the gripper and the deflecting unit does not have the ability to rotate in a horizontal plane, which makes it difficult to aim the grab with the deflecting unit on a standing tree, and the winch is rigidly mounted on a self-propelled chassis, which causes the perception of static and dynamic loads on the chassis of the chassis when winch operation.

These drawbacks are eliminated by the fact that in the proposed forestry machine, which includes a self-propelled chassis, on which technological equipment is mounted, containing a winch with a freight cable, a gripper with a drive and a deflecting unit for a freight cable is mounted on its free end, and a device for holding the transported bundle on the machine , the boom is mounted on a self-propelled chassis with the possibility of its rotation around a vertical axis by means of a mechanism, and the winch is mounted with the possibility of its removal from a self-propelled the chassis to the ground when skidding using a mechanism, such as pivoting levers mounted pivotally at one end on a self-propelled chassis, and pivotally connected at the other ends to the axis of the winch drum, the rotation of which is via power hydraulic cylinders, with the longitudinal axis of the winch drum parallel to the longitudinal axis of the self-propelled chassis.

In the proposed forestry machine, it is much easier to pick up a grapple with a deflecting block on a standing tree, which increases productivity, while skidding, static and dynamic loads on the chassis of the self-propelled chassis are significantly reduced, there is no need to load the brake system and transmission of the self-propelled chassis.

In the patent and scientific and technical literature, we did not find such a design of a forestry machine.

Figure 1 shows a forestry machine, rear view, during skidding; figure 2 is the same, a top view (the crown of the tree on which the deflecting unit is mounted, and the device for fastening the packs on the machine is not shown).

The logging machine includes a self-propelled chassis 1, on which technological equipment is mounted, including a winch 2, boom 3 and a device for holding the transported bundle 4. Boom 3 is equipped with drives 5 and 6 to change its reach and mounted on a rotary column 7, which is mounted in the pipe 8 The rotary column 7 is equipped with a mechanism 9 for turning it around a vertical axis 10, for example, hydraulic cylinders with rod stocks in contact with a ring gear rigidly connected to the rotary column 7. Moreover, the hydrocylin The cores are mounted on the pipe 8. At the free end of the boom 3, a gripper 11 is installed with its drives (not shown) and a deflecting unit 12 for the cargo cable 13, which is attached at one end to the winch drum 2. The pipe 8 is rigidly fixed to the self-propelled chassis 1. Winch drive 2 can be carried out from the hydraulic motor 14 through the reducer 15. The winch 2 is mounted on a self-propelled chassis 1 by means of levers 16, one ends pivotally mounted on brackets 17, rigidly mounted on a self-propelled chassis, and the other pivotally connected to the axis 18 of the winch. The rotation of the levers 16 is carried out by a drive consisting of hydraulic cylinders 19, pivotally mounted on a self-propelled chassis 1, and rods pivotally connected to the rockers 20, some ends pivotally mounted on brackets 17, and the other ends pivotally connected to rods 21, which are free ends pivotally connected to levers 17 between the axes of their rotation with hinges of communication with the winch 2. The winch 2 is equipped with a support 22, rigidly connected with the body of the winch 2.

The forestry machine operates as follows.

The harvesting machine can skid both separately lying trees (whips) on the cutting area, as well as prepared bundles after the feller buncher, as well as transport bundles in a completely submerged position.

The harvesting machine calls into the cutting area with fallen trees (whips) or small bundles prepared by a feller buncher, the operator, controlling the drives 5, 6 and 9, uses the arrow 3 to capture 11 with the deflecting unit 12, through which the freight cable 13 is passed, onto the trunk one of the left seed trees 23 and fixes it. Next, the operator includes hydraulic cylinders 19 and a winch 2, sets it on the ground until it stops with its support 22, while leaving the hydraulic cylinders 19 in the "locked" position. Then the fallen trees 24 or small bundles 25 are choked, the operator turns on the hydromotor 14 of the winch 2 to wind the load-carrying cable 13. Thereby, the mocked trees are formed into a bundle and skidded by it or hooked bundle, prepared by a feller buncher, to the seed tree, where it is uncoupled and leave the pack. Next, the cycle is repeated until all the trees or small bundles in the sector behind the testis tree are re-mowed to the length of the load-bearing cable 13. The skimmed (mowed) bundles are fan-shaped at the seed tree. After skidding of all available trees (whips, not large bundles), the logging machine 1 moves to another parking lot and the skidding cycle is repeated as described. Before moving the machine to another parking lot, the operator, controlling the drives 5, 6, 9 and 19, puts the gripper 11 with the deflecting block on a self-propelled chassis 1, and sets the winch 2 on a self-propelled chassis. In the future, packs are transported by any of the known methods: choker machines; skidding machines with a manipulator and a conic; skidding machines with a pack of tongs; podrelevannye packs are divided into assortments, loaded with a gripper 11 and an arrow 3 in the device 4.

In the proposed forestry machine, by reducing the time it takes to pick up a grip on a seed tree, productivity increases, and by reducing the load on the undercarriage of the self-propelled chassis, its durability increases.
