Description

(54) WORKING ORGAN OF MILLING MACHINE

one

The invention relates to machines for milling soil covered with woody vegetation in the preparation of areas for peat extraction, for loosening and crushing soil for road construction, as well as for layering the soil in the grooves and channels.

Known working body for loosening, including freely rolling, not having a drive rotor with loosening elements, made in the form of a tape, located on the periphery of the rotor and supporting elements mounted along its length, on which the belt knives 1 are supported.

However, this cultivator can only work on weak soils and is not able to grind wood and grass vegetation, and since it does not have a drive, it is not reliable enough.

Known milling working body, including mounted on the frame of the cutter with cutting knives and drive gear and located in front of the cutter with a gap baffle plate with a shear knife 2.

The disadvantages of this working body are knifing by knives with vegetation.

and heavy soil, which leads to an increase in the energy intensity of the working process, as well as to the emergence of the cutter on moist soils, which significantly reduces the productivity of the maschine. In addition, knives are often broken, and a large number of knives on the cutter lead to a waste of time to replace them. The design of the milling cutter and cutting elements does not allow working on large feeds per knife, which also reduces the productivity of the machine. It should be noted that the geometrical shape of the cutter does not ensure the correct positioning of the inertial mass in order to use its inertia when chopping wood inclusions with a knife, which also reduces the productivity of the mash 5.

The purpose of the invention is to increase the productivity and reliability of the working body.

Claims (2)

The goal is achieved by the fact that the cutter is made of a series of successively placed discs interconnected peripherally by means of planks fixed with displacements relative to each other, on which cutting knives are fixed, located in the same plane with the planks; the ends of the cutter mounted on the support ring, which is equipped with a gearbox. FIG. 1 shows a milling machine general view; in fig. 2 - milling unit with gear. The milling machine aggregates with tractor 1 and is driven by a power take-off shaft. It includes a frame 2, on which a baffle plate 3 is installed with a shear knife 4, an onboard gearbox 5, a milling cutter 6 and a rear supporting roller compactor 7. The milling cutter consists of supporting figured disks 8, connected along the periphery by massive strips 9, offset from both sides of each disc relative to each other at a certain angle. The slats perform the role of the flywheel cash registers, and replaceable cutting knives 10 are attached to them. The end strips 11 rest on a ring 12 which concentrically surrounds the drive reducer 13 connected through the shaft 14 to the bearing disc 15. The number of supporting discs and connecting slats forming a row sections, determine the width of the cutter. The required distance between the support discs is chosen in such a way that the sections are not clogged with vegetation residues and soil. A set of knives on the cutter can be carried out along a helix, herringbone, or any other type most rational for the execution of the technological process. Milling machine works as follows. When the milling machine operates, rotation from the tractor's power take-off shaft is transmitted via transmission to the bead gear 5 and then to the gear 13 of the cutter. From the gearbox 13, by means of a shaft 14 connected to the supporting disk 15, the rotation is transmitted to the milling cutter 6. A ring 12 concentrically covering the drive gearbox. creates additional support for the end strips 11, thereby achieving reliability in the operation of the extreme knives 10. The milling machine in the process of work places woody vegetation on the soil. Fender plate 3 presses the woody vegetation to the soil, and the mill 6, recessed into the ground; rotating, knives 10 mills the soil together with wood. The milled mass is thrown back and rolled by the rear roller 7. When milling, the shearing knife 4 mounted on the baffle plate and the cutting knife 10 of the cutter are the two halves of the shears between which the wood vegetation is cut. The invention The working body of the milling machine, comprising a milling cutter mounted on the frame with cutting knives and a driven gearbox and an otboyny plate with a shearing knife positioned in front of the gap cutter, characterized in that the cutter is made of a row parallel placed disks interconnected along the periphery by means of planks fixed with displacement relative to each other, on which cutting knives are fastened, which are located in one plane with the planks spine, with the strap at the ends of the cutter mounted on the support ring, which is equipped with a gearbox.
