The invention relates to the field of technological equipment forestry machines manipulator type, namely the support-rotating devices, and can be used in the forest industry and forestry.

Known rotation device of the manipulator harvesting machine, comprising a tube mounted on the U-shape is inserted into the tube of the rotary column, on which is mounted manipulator with its actuator, and the rotation mechanism of the manipulator in the horizontal plane (kussakin N. F. The design and operation of the skidders: Educational. allowance for vocational schools. - M.: Genre Differences. prom-St, 1985, - 272 S., see pages 136 and Fig.79).

Known rotation device of the manipulator harvesting machine is used, generally, to machines of small and medium capacity and a rotation angle in the horizontal plane less than 360o.

Closest to the invention is a rotation device of the manipulator harvesting machine, comprising a support rotatable roller, lower fixed part which is fixed on the frame mounted rotatable platform, which includes a manipulator and a rotation mechanism platform with manipulator in the horizontal plane relative to the frame of the self-propelled chassis, including the engine and gearbox on the output shaft which is rigidly mounted a leading gear that is in mesh with a ring gear fixed part (Feller-Bunchers machine PL-19. Kruglov C. S., Berman M. A., B. N. Ermolov , Queens, C. E., Popov, B. C., M.: Genre Differences. prom the terrain, 1982, 288 S., see page 15 Fig.5, page 20 Fig.9, page 21 Fig.10 and page 33 Fig.19).

Known rotation device of the manipulator harvesting machine has the disadvantage that the leading gear on the output shaft of the gearbox installed the console, and with considerable loads on the manipulator is misalignment pinion and ring gear, and the engagement is not along the entire length of the teeth, resulting in reduced durability and even fracture of the teeth.

To eliminate this drawback in the support-rotating device of the manipulator harvesting machine, comprising a support rotatable roller, lower stationary part which is rigidly fixed on the frame of the self-propelled chassis and is provided on the inner circumference of the ring gear, and echanism platform rotation with the arm in a horizontal plane relative to the frame of the self-propelled chassis, on the output shaft of the rotation mechanism established leading gear that is in mesh with a ring gear fixed part under the lower fixed portion rigidly mounted ring with a flange on the inner diameter of the ring, and the outer surface of the flange is made in the shape of a truncated cone, the small diameter facing down, at the free end of the output shaft of the rotation mechanism installed faceplate with the ability to rotate it about the vertical axis of the output shaft, with the face-plate is rigidly connected to the bracket at the free end which has a cone-shaped roller with the possibility of running it on a conical surface of the flange during rotation of the platform, or on the faceplate hard-coded a few brackets with the tapered rollers at their free ends, and the longitudinal axis of the brackets are angled to each other, between the output shaft of the rotation mechanism and the faceplate is installed shims.

In this embodiment of the device eliminates the console output shaft of the rotation mechanism of the platform, eliminates the bias in the engagement of the teeth of the pinion and ring gear, which increases the reliability and durability of the device.

In PA sociologically machine we have not identified.

In Fig. 1 shows a rotation device of the manipulator harvesting machine, the section of Fig.2 is a view along arrow a in Fig.1.

Rotation device of the manipulator harvesting machine includes a support rotatable roller containing the lower stationary part 1, which is rigidly through holes 2 is fixed via a support ring on the frame of the self-propelled chassis (Fig.1 conditionally support ring and the frame is self-propelled Chasse not shown), the upper movable portion 3, on which is rigidly mounted swivel platform 4 with a handle (not shown) and a rotation mechanism 5 turntable 4 with the arm in a horizontal plane relative to the frame of the self-propelled chassis. The upper movable part 3 is mounted for rotation relative to the lower fixed part 1 on the rolling elements 6, for example rollers. Under the lower fixed part 1 is set to a ring 7 with the flange 8. The ring 7 is stationary relative to the lower fixed part 1, as attached through the hole 2 in conjunction with part 1. The outer surface 9 of the flange 8 is made in the shape of a truncated cone, the small diameter facing down.

On the output shaft 10 is rigidly mounted a leading gear 11, tho shaft 10 is installed faceplate 13 can be rotated about the vertical axis of the output shaft 10. C faceplate 13 rigidly connected to the brackets 14, the longitudinal axis 15 which are located at an angle to each other. Brackets 14 may be one, or two, or even three. At the free ends of the brackets 14 are tapered rollers 16 with the possibility of rotation around its axis and spinning cone on the outer surface 9 of the flange 8 when the rotation of the platform. Between the output shaft 10 and the faceplate 13 is installed shims 17 and the bearing 18. Faceplate 13 is mounted on the output shaft through the washer 19 by bolts 20.

Rotation device of the manipulator harvesting machine operates as follows.

The statement includes a rotation mechanism 5 turntable 4. When the output shaft 10 with the pinion 11 is forced to rotate around its vertical axis and rotating in bearings 18 and 21, the teeth of the pinion 1 will be our teams on the toothed crown 12 of the fixed part 1. The upper movable part 3 together with the turntable 4 rotates in a horizontal plane on the rolling elements 6, and the face-plate 13 with the bracket 14, the driven output shaft 10, will make a rotation around the vertical axis of the output shaft 10 and gear 12. If this is th 1 are interconnected through the faceplate 13, the brackets 14 and the tapered rollers 16, are practically eliminated the console output shaft 10 and the bias in the engagement of the teeth of the driving gear 11 and the ring gear 12.

In the process of installation and operation can be adjusted clearance in the engagement of the driving gear 11 and the gear 12 by the movement of the rotation mechanism 5 on the rotary platform 4 and the diminution or addition of a number of shims 17, thereby raising or lowering, respectively, the tapered rollers 16.

In such a constructive implementation of a turntable manipulator forest machines virtually eliminated the bias in the engagement of the teeth of the driving gear 11 and the ring gear 12, which eliminates the bummer and chipping of the teeth and improves the reliability and durability of the device.
