The invention relates to the technical equipment forestry machines, namely the communication of the working body with the manipulator forest machines, and can be used in the forest industry and forestry.

Known rotator manipulator harvesting machine, comprising a housing that has single-vane torque hydraulic cylinder, the shaft of which is connected to a manipulator (Alexandrov VA, Scholl E.G. Design and calculation of machinery and equipment for lumbering operations and the bottom of the warehouses. The tutorial. - Ukhta: Ural state technical University, 2003. - 244 C., see str, 13...16 lines from the top, and is on str).

Known rotator manipulator harvesting machine has a relatively complex structure and the angle of rotation around the vertical axis of the working body less than 360° (2 P).

Also known rotator manipulator harvesting machine, comprising a casing, a pivotally mounted arm, and comprising inside of the two cavities, the upper of which is made in the form of a hydraulic cylinder of the reciprocating movement, the piston rod of which is made in the middle part, the length, in the form of a threaded screw, a member engages with a nut rigidly mounted in the partition between the upper and lower cavities in the bottom cover bottom cavity made guides for the rod, a supply-re is d power made one in the upper chamber, and the other at the bottom, working body mounted on the rod below the lower cover (Emtel Z.K. Improvement of kinematics, dynamics and design of timber hydraulic cranes. Abstract of thesis ... Dr. t. Sciences: 05.21.01. /Skencil. - Voronezh, WGLT, 2002. - 36 S. see figure 2 on page 10).

However, the known rotator manipulator harvesting machine has a rigid connection of the piston rod and a threaded screw, which causes the complex movement of the piston (reciprocating and rotary) and increased wear, hampered the flow of the working fluid in podporchennuyu cavity and draining out of her.

To correct noted deficiencies in the proposed design rotator manipulator harvesting machine, including a housing pivotally mounted on the arm and comprising inside of the two cavities, the upper of which is made in the form of a hydraulic cylinder of the reciprocating movement, the piston rod of which is made in the middle part, the length, in the form of a threaded screw, a member in engagement with the nut, and the bottom cover bottom cavity made guides for the rod, while the upper cover and on the rod of the cylinder, below the lower lid, mounted the means for fastening of the working body and attaching to the manipulator according to the invention the rod made of two parts connected merbaby rotational-axial connection above the threaded portion, a nut rigidly fixed in the partition mounted rigidly in the lower cavity, and a partition between the upper and lower cavities installed seal for the rod, and a supply-drainage of hydraulic oil in the top cavity: one above the piston, and the other below the piston. In addition, the body is made detachable.

This design of the rotator manipulator harvester eliminates rotation of the piston in the housing, facilitates supply-removal of oil, facilitates Assembly and disassembly of the rotator and increases the reliability of his work.

Figure 1 shows the rotator manipulator harvesting machine, kind of a General, schematic section; figure 2 is the same, the rotational-axial connection of the stem.

The rotator arm harvesting machine includes a housing 1, which internally consists of two cavities a and B.

Cavity And represents the cylinder of the reciprocating motion, the piston 2 which is connected to a rod 3 and a seal 4, for sealing of the piston 2 in block 5 of the cavity A. the bottom cover 6 cavity (block 5) installed gasket 7 for sealing the piston rod 3 and the top cover 8 is rigidly fixed to the bracket 9 for connection of the housing 1 with a crane machine (not shown).

Cavity And provided with inlet-outlet 10 and 11 of the hydraulic oil in newportnews and the current space. To the bottom cover 6 is attached rigidly with the possibility of removing the body cavity 5, consisting of two halves 12 and 13, between which there is a partition 14 is rigidly secured therein by a nut 15.

The rod 3 within half 12 is connected with its screw part 16 of the rotational-axial connection (figure 2) by means of spring rings 17 of rectangular profile. Below the coil part 16 of the piston rod 3 has a cylindrical section and through the guide 18 passes through the cover 19, the outside of which is provided with a device 20 for connection with a work machine body (not shown).

The rotator can be connected to the manipulator device 20, and a working body through the bracket 9.

The screw part 16 of the shaft 3 and the nut 15 is made with hard carving a rectangular profile.

Part 5, 12, 13, 14 and 19 of the housing 1 are connected to each other rigidly, but are easily parsed structure, such as a bolt (flange) connection or threaded with the inner and outer threads.

Rotator manipulator harvesting machine operates as follows.

The operator, by controlling the rotator delivers the pipework through the inlet 10, the piston 2 under the pressure of the liquid is lowered together with the rod 3 down and pushes the screw part 16, which, being in engagement with a nut 15, starts to rotate around its longitudinal axis and to rotate the work of the organization is (not shown). It will rotate clockwise or counterclockwise, depending on the thread (right or left). From under the piston 2, the pipework will be discharged through the outlet 11. Turn the working body at a desired angle, the operator raises the piston 2 in the "lock" position and the load is suspended on the piston 2 and the thrust of the thread of the nut 15 and the screw part 16 of the piston rod 3. When the supply of oil in the inlet 11 and the outlet through the outlet 10 of the piston 2 will move up, and turn the working body in the other direction. When the rotation of the working body of the subject's work piston 2 is placed by the operator in a "floating" position. The maximum angle of rotation of the working body depends on the thread pitch, the length of the coil part 16 of the piston rod 3 and the stroke of the piston 2.

The proposed construction of the rotator manipulator harvesting machine allows as the upper part (cavity And the use of standard hydraulic cylinder, prevents rotation of the piston facilitates Assembly-disassembly, maintenance of the rotator and supply-drainage of oil).
