Description

The invention relates to forestry equipment and can be used to move delimbers. A device for moving the delimbing machine is known, which contains power cylinders hinged on the frame of the machine and support plates with a ground engaging device 1. A disadvantage of the known device is the limited speed of movement imparted by the delimbing machine due to the design possibilities of the device. The purpose of the invention is to reduce the time to move the maschina. This is achieved by the fact that two rocker arms are connected to the frame, which are connected to the power cylinders and equipped with pushing shanks. FIG. 1 shows the proposed device in the transport position; in fig. 2 - the same in the working position; in fig. 3 - hydraulic circuit of the device. The proposed device is mounted on farm 1 and consists of hydraulic cylinders 2 and 3, the rods of which are connected with rocker arms 4 and 5, which are hingedly mounted on the lower section of the farm 6 / using common pox 7. The rocker arm 4 5 is also connected to the rods 8 and 9, on which support plates 10 are fixed with a ground-heating device I. Rods 8 and 9 swivel with rocker arms 4 m 5 are made with stops 12. having the ability to interact with the bottom 6 som truss / when translating rods 5 and 5 into the transport position . At the bottom of the cross 6 truss / fixed latch 13, which secures the rods S and, 9 in a raised horizontal position. The device is controlled from the operator's cab 14 by means of a hydraulic distributor 15. connected to the hydraulic cylinders 2 and 5 by pipelines 16, and gates 17 to 18, which automatically fold the rocker-rod pair during transport. The device works as follows. The operator from the cab 14 turns on the hydraulic distributor 15, while the valve 17 is closed, the valve 18 is open, and the working fluid enters the rod cavity of the hydraulic cylinder 2, the rod of which rotates, turns the rocker arm 4, and abutting the rod 5 into the ground through it. The conversion of farm 1 by one step takes place. At the same time, the working pressure is received.

In the piston cavity of the HPD, the stem of which extends and rotates the rocker arm 5 in the opposite direction. At the same time, the rod 9 slides on the surface of the outer plate 10, without being buried in the crawler. After that, the operator switches the valve 75 to the reverse, and the next step takes place. At the same time, a friend of the rocker sink is working. The rod of the hydro pylipod 3 is retracted and rotates the beam 5 and, through it, presses the rod 9, which wears into the plate W with the device //. shifts the farm / pas niar. At this time, hydrojlipdr 2 returns the yoke 4 to the Tanguar 8 to its original position. In this way, continuous locking of the looming machine is carried out.

For the irivedep device, the operator opens the valve 17 into the transport position, and the valve 18 closes, and when the hydraulic distributor 15 is turned on, the working fluid enters the schtokovye cavities of both hydraulic cylinders 2, which, acting on the rocker arms 4 and 5, leads them to the horizontal position At the same time, the stops 12 on the rods 8 and 5 slide along the lower leg 6 of the truss /, turning the rods 8 and 9 to the horizontal transport position in which they are fixed by the latch 13.

The ability to move the delimbing machine continuously allows you to save working time on this operation, as well as not involve other mechanisms for this purpose. As a result, the performance of the deliming machine with the irimeneppen of such a device increases by 5-7%.

Formula and 3 onbreten p

The device for stirring, cutting the delimbing machine, containing power shields and power plates mounted on the frame of the machine and supporting plates with a ground engaging irisosoblennoem, is due to the fact that, in order to shorten the time for unreplaceable machines, the frame is attached to the frame. , coupled with power cylinders and equipped with pushing cables.
