The invention relates to machines harvesting manipulator type and can be used in the forest industry and forestry.

Known harvesting machine, comprising a self-propelled chassis, which by means of pivot roller mounted rotary platform mechanism with its rotation, operator cabin, power unit, a compartment with hydraulic units, storage tanks for fuel and working fluid for the hydraulic system, a hydraulic manipulator with gripper-cutting device and the counterweight (Kossev VF Harvesting machine manipulator type. - M.: Forest industry, 1981, 248 S., see Fig.5 and p.40 3...14 lines from the top).

In the known machine logging counterweight stationary relative to the rotary platform and in this regard to ensure the stability of the machine when the maximum departure of the manipulator with gripper-cutting device counterbalance weight great that very weight machine.

Also known harvesting machine, comprising a self-propelled chassis, which by means of pivot roller mounted rotary platform mechanism with its rotation, operator cabin, power unit, a compartment with hydraulic units, storage tanks for fuel and working fluid for the hydraulic system, a hydraulic manipulator with gripper-sesaudi the device and the counterweight, installed with the possibility of movement relative to the rotary platform depending on departure manipulator (Misurkin P.M. Search construction forestry equipment. - Moscow: Publishing house of Saratov University. Saransk branch, 1990. - 304 S., see RIS on p.157 and line 1...6 bottom on PP 156 and line 1...2 on top p.157).

Known harvesting machine also has a counterweight that weight machine, and at the maximum departure of the manipulator increases the size of the back of the machine, which may hinder the rotation of the turntable when selective felling and thinning, which reduces the technological capabilities of the machine.

The technical result of the proposed machine logging is to reduce the size and weight of the machine.

The technical result is achieved in that in a harvesting machine, comprising a self-propelled chassis, which by means of pivot roller mounted rotary platform mechanism with its rotation, operator cabin, power unit, a compartment with hydraulic units, storage tanks for fuel and working fluid for the hydraulic system, a hydraulic manipulator with a working body, for example gripping-cutting device, and a counterweight mounted with the possibility of movement relative to the rotary platfo who we are depending on the departure of the manipulator, the novelty lies in the fact that the counterweight is made in the form of a compartment with hydraulic units, tanks for fuel and working fluid for the hydraulic system and power unit mounted on the supporting framework, with the possibility of rotation around the horizontal axis in the vertical longitudinal plane of the vehicle by means of two shoulders of the lever, one arm associated with the auxiliary platform and the other with a hydraulic manipulator, with the axis of rotation of the auxiliary platform and two shoulders of the lever is fixed on the rotary platform, and the two shoulders shoulder of the lever associated with the auxiliary platform made U-shaped, with U-shaped shoulder, two shoulders of the lever is made asymmetric relative to the longitudinal axis of the manipulator, and the counterweight can be performed consisting only of units of the hydraulic system and tanks.

Such constructive execution of the machine logging will be used as a counterweight units of the machine, which reduces the weight of the car, the installation of hydraulic units and tanks to the auxiliary platform, and the engine is on a rotary platform will allow you to remove them from each other, which will have a positive impact, for example, in case of fire, when reducing the departure of the manipulator, as it occurs, as a rule, with the load; an auxiliary platform h is cut two shoulders lever increases the force on the actuator of the manipulator, and all of the above increases the efficiency of the machine.

In the patent and scientific literature of a similar construction machine harvesting we have not identified.

Figure 1 shows a diagram of the machine logging, side view; figure 2 is the same, the end position two shoulders arm and manipulator; figure 3 is a view along arrow a in figure 2; figure 4 is a view along arrow B in figure 2, rotated.

Machine harvesting, including self-propelled chassis 1 on which is mounted by means of pivot roller 2 swivel platform 3 with the mechanism of its rotation around the vertical axis (not shown)which includes an operator's cab 4, the power unit 5, the compartment 6 with the hydraulic units, storage tanks for fuel and working fluid for the hydraulic system, hydraulic crane 7 working body 8 at its free end, for example, the gripping-cutting device. Compartment 6 and the power unit 5 is mounted on the supporting framework 9 can rotate around the axis 10, is mounted in the bracket 11, which is rigidly fixed on the rotary platform 3. Power unit 5 can be mounted on the rotary platform 3 and the compartment 6 on the supporting platform 9, and Vice versa that depends on the maximum load moment of the machine, since the supporting platform 9 with the mustache is set out on the units acts as a counterweight. On the rotary platform 3 by means of axis 12 and bracket 13 mounted two shoulders lever 14, the shoulder 15 which is made U-shaped, with the lever 14 from the compartment 6, and the other shoulder 16 with the arm 7. The shoulder 15 provided with rollers 17, paired with the guides 18, rigidly connected with the supporting platform 9. The shoulder 16 at the free end provided with a cross member 19 for contact with the arm 7. For the free rotation of the shoulder 16 in the arm is made through slot 20. The shoulder 15 is made asymmetric with respect to the shoulder 16, as part of the compartment 6 is located behind the operator's cab 4. The arm 7 is connected through the axis 21 with the rotary platform 3 and is provided with actuators 22, 23 and 24, for example by hydraulic cylinders.

Machine harvesting is as follows.

The operator controls the actuators 22, 23 and 24, and a rotation mechanism (not shown) of the rotary platform 3, changes the magnitude of the departure of the manipulator 7 and directs the working body 8 on the subject of work, such as tree 25, captures it, if necessary, cuts and moves in the desired location and stacks. Almost always changes the value of the load moment (tipping) of the manipulator 7, but since the hydraulic crane 7 is connected two shoulders lever 14 with the compartment 6 (contrast), then increasing departure of the manipulator 7 (increase opacity the surrounding of the time) the center of gravity of the compartment 6 will move away from the axis 21 of rotation of the manipulator 7 (see figure 1 and image dotted lines in figure 2) and thereby increase the magnitude of the stabilizing moment, and Vice versa. When the tightening and lifting of the object of labour by the manipulator 7, the center of gravity of the compartment 6 will, in addition to proximity to the axis 12, down and across the two shoulders lever 14 to increase the force of rotation of the manipulator 7.

Proposed harvesting machine allows you to use as opposed to units of the machine, without adding weight to its counterweight, the unit design of the hydraulic system on an additional platform, and the motor on the rotary platform and Vice versa allows you to increase the fire safety of the machine, while reducing the departure of the manipulator, and this happens usually with the load, additional platform through two shoulders lever increases the force on the actuator of the manipulator, and all of the above increases the efficiency of the machine logging.
