Description

one

The invention relates to machines for the preparation of land for agricultural use.

By ocHOBHONiy auth. St. No. 474321 izheogen ragger is a wood chopper, including a self-propelled chassis, a frame on which a rotated rotor is mounted, in front of which, in mobile supports, on the longitudinal beams, a rotor-measuring device is installed, which has a greater rotational speed than the rotor. The chopper rotor is closed by a protective cover with a counter knife. The protective cover is simultaneously a pressure bar,

The disadvantage of such a shredder is that the shrub rooting is done without cutting or cutting the roots. With such a grub, great efforts are made on the teeth of the gnawing rotor, which reduces the chances of a grubber when grubbing large-diameter trees.

The purpose of the invention is to reduce the efforts of korcheva51i.

This is achieved by installing circular saws mounted on a common drive shaft, the axis of rotation of which is horizontal and perpendicular 1; coolantly to the longitudinal axis of the tatcher, in front of the rocking rotor. Drive shaft mounted on swing frame

FIG. 1 shows a rooting device, a general view; in fig. 2 - node I; in fig. 3vid from above on circular saws and a power shaft.

The wood shredder includes a self-propelled chassis 1, carrying a spatial joint-joint frame 10, on which is mounted a rotated rotor 3.

The roaring rotor is a shaft 4 with teeth 5 mounted on it. On the axles of the shaft of a roaring rotor 3, a rotor is freely mounted. The rotor is crushed 6 with knives 7, located in front of and in close proximity to the roaring rotor. The supports 8 under the influence of the adjusting screws 9 can be moved lio by the guide 10 of the longitudinal beams 11, the measuring rotor is closed by the casing 12, which is also pressed down (a new bar. To increase the rigidity the casing is provided with ribs 13, which are made sharp and at the same time are knives An anti-cutter blade 14 is mounted on the casing. Between the roaring rotor 3 and the rotor-chopper 6, a cleaner 15 is installed, equipped with the teeth 16 passing between the teeth of the rotazing rotor Rama 2 with the front part resting on the ground rollers 17, and days, the packer, the roller 18, the rear and the front parts of the frame 2 are interconnected by means of the hinges 19 and the power cylinders 2O. The front cylinders 21 are connected to the chopper rotor 6. There are discs in front of the writhing rotor saws 22 mounted on a common drive shaft 23. The axis of rotation of which is located horizontally and alternately with the longitudinal axis of the hopper. The drive shaft 23 is mounted in swing frame 24 supports 24. Swinging frames are connected to the self-propelled chassis by means of a hinge 26 and hydraulic cylinders 27. A blade 28 is installed in front of the drive shaft 23 and connected to the self-propelled frame right now with bars 29. The power removed from the power take-off shaft of the self-propelled chassis is transmitted to the grinning rotor, the rotor-chopper and the drive shaft via hydraulic drive 30. Works Roofing - wood shredder clIeduyutsi f way. When the lifter moves, the circular saws 22 mounted on a common drive shaft 23, receiving a torque from the hydraulic drive 30, turn back and under the action of hydraulic drives 27 are buried in. the soil and cut into it narrow parallel slits, and cut the found roots and the aerial part of the tree vegetation. The roaring rotor 3 is lowered and eag / 1 is driven into the ground by means of sipov cylinders 20 and, getting rotation from hydraulic drive 30 and rotating in the direction opposite to the uproader movement, the root system of the shrub and fines are removed from the ground 5 and feeds it to the knives 7 the rotor is from fells 6 having a high rotational speed in the opposite direction. The rotor of the shredder rotates through the hydraulic drive 30, the rotor knives of the shredder, interacting with the shear knife 14, chop the wood into small fractions that mix the teeth of the shunting rotor 3 with the ground and roll in the roller 18. Teeth 16 of the cleaner, 15 prevent the scrub from rolling on the roaring rotor and the throwing of large pieces of wood behind the roaring rotor. The necessary force to press the shrub to the ground and the low-density woods by the casing 12, which is simultaneously a pressure bar, is provided by the force cylinders 21. The ribs 13 cut the branches of the shrub and the small-woodlands and stabilize the rotor-shredder position. To maintain the optimum clearance between the 7 rotor - the chopper 6 and the teeth 5 of the roaring rotor 3, the center distance between the shafts of the roaring rotor and the chopper rotor is changed by means of adjusting screws 9, which move the support 8 along the guides 1O of the longitudinal beams 11. Shrub roll and sprays is produced by a blade 28, which simultaneously protects the drive shaft 23 and the circular saws 22 from tree damage. In the transport position, the frame 2 together with the writhing rotor 3 is raised by means of power cylinders 2Oi and redstvom actuators 21.podnimaets rotor - 6. chopper. The drive shaft 23 with circular saws 22 is raised by hydraulic cylinders 27, Formula 1. Invention 1. Wood chipper-chopper according to ed. St. No. 474321, about tl and h ach and and with. In that, with a chain of reducing the force of pulling, circular saws mounted on a common drive shaft are mounted in front of the rotor, 2. The hooker according to claim 1, distinguishing ush and also with the fact that the drive shaft is mounted on a swing frame. 2S 22
