Abstract

FIELD: agriculture.

SUBSTANCE: machine comprises a self-propelled chassis, a tractor engine which actuates the generator with an electric saw, and a load winch with rope-choker equipment. On the loading platform, located on the undercarriage of the self-propelled chassis, in its middle the transfer case is mounted. The transfer case is connected by the gimbal drive to the engine of the tractor. On the transfer case output shafts with the help of clutches on one side a generator is mounted which is connected with a cable to the electric saw, and the load winch with rope-choker equipment, and on the other side a delimbing device and a chipping machine are mounted with clutches.

EFFECT: growing technological capacity of a machine to perform work connected with the harvesting and primary processing of timber at thinning operations.

Description

The invention relates to forestry and can be used for logging while caring for the forest.

Known devices for conducting thinning forest care (patents No. 2121265, 2101925, 2064759), consisting of a rotary boom mounted on a self-propelled chassis with a gripping-cutting device and an inclined platform.

Known devices perform a limited number of operations when performing work related to the harvesting of timber, and do not process chopping residues.

The closest in technical essence and the achieved economic effect is the device (Shirnin Yu.A., Posharnikov F.V. Technology and equipment for low-volume logging and reforestation: Textbook. - Yoshkar-Ola: MarSTU, 2001 - p. 63 and p. 138 ), containing a self-propelled chassis, a tractor engine, driving a generator with an electric saw, as well as a winch with cable-choker equipment.

The known device does not provide the full range of work associated with the procurement of timber and their further primary processing.

The problem solved by the applicant is the expansion of the technological capabilities of the device when performing work related to the harvesting and primary processing of timber in thinning.

This goal is achieved by the fact that on the cargo platform, located on the undercarriage of the self-propelled chassis, in its middle there is a transfer case connected by means of a cardan drive to the tractor engine, and on its output shafts using clutches, on one side, a generator connected by cable to electric saw, and a cargo winch with cable-choker equipment, and on the other hand with the help of clutches - a delimbing unit and a chipper.

The device for conducting thinning is illustrated by drawings, where in Fig. 1 a side view is shown, in Fig. 2 is a top view, in Fig. 3 is a diagram of the operation of the device.

The present invention consists of a loading platform 1, located on the undercarriage of a self-propelled chassis 2, on which a transfer case 3 is mounted in its middle, connected by a cardan gear 4 to the tractor engine 5, and on its output shafts using clutches 6 mounted on one side a generator 7 connected by a cable 8 with an electric saw 9, and a cargo winch 10 with a rope-choker equipment 11, and on the other hand, using a clutch 6 - a delimbing unit 12 and a chipper 13.

The present invention works as follows (figure 3). The machine arrives at the place of logging. In this case, the selection is prepared in advance by cutting the main 14 and apiary 15 draggers. The length of the apiary 16 will depend on the taxation indicators of the allotment, as well as on the length of the cable 8 and the cable-choker equipment 11 of the cargo winch 10. Development is carried out with tapes 10 ... 15 meters wide. The device is installed opposite the tape. From the transfer case 3, connected with the tractor engine 5, the torque is transmitted to the generator 7, which generates electricity, and it drives the electric saw 9 through the cable 8. Using the electric saw 9, a 1 meter wide sight is cut along the tape axis. Then the trees are felled in the direction of the apex to the middle of the tape. After that, cable 8 is wound onto a drum, and a rope with chokers is pulled along the sight. The trees are choked, and then with the help of a cargo winch 10 they are pulled to the car. If the diameter of the trees exceeds 12 cm, then with the help of the delimbing unit 12, knots are cut from them, and later with the help of an electric saw 9 they are cut into assortments 17 and stored on the opposite side of the machine. The resulting branches are sent to the chipper 13. If the diameter of the trees is less than 12 cm, then they are sent immediately to the chipper 13 with the subsequent collection of wood chips in bags 18.

Timber is taken out from the cutting area by sortimentovoz carriers, and wood chips can also be taken out and used as fuel, or they can be scattered around the section where felling was carried out as organic fertilizer.

After carrying out work on one tape, the machine moves to a new position, and when the work is completed on the main drag, the machine is transferred to the main drag located on the opposite side of the ramp.

When using this device, the entire complex of logging operations, as well as processing of logging residues, is performed. Tape operations are carried out carefully, without damage to the remaining trees. At the same time, logging residues are disposed of, which reduces the risk of forest damage by biological diseases, and also reduces the risk of fires.
