изобретение относитс к машинам дл фрезеровани грунтов, покрытых древесной растительностью при подготовке площадей дл добычи торфа, а также дл рыхлени и измельчени грунта при дорожном строительстве .The invention relates to machines for milling soil covered with woody vegetation in the preparation of areas for peat extraction, as well as for loosening and grinding the soil during road construction.

известен рабочий орган фрезерной машины , содержаший корпус и рабочие элементы с режущими кромками 1.Known working body of the milling machine, containing the body and work items with cutting edges 1.

Наиболее близким по техническому решению к предлагаемому изобретению вл етс рабочий орган фрезерной машины, содержащий корпус: в виде дисков,, скрепленных планками, имеющих режущие кромки , и образующими фрезу с продольной осью, и противорежущий нож 2.The closest to the technical solution of the present invention is the working body of the milling machine, comprising a body: in the form of disks, fastened with planks, having cutting edges and forming a milling cutter with a longitudinal axis, and a counter knife 2.

Однако работа мащины, оснащенна данным рабочим органом, сопровождаетс высокими динамическими нагрузками вследствие лобового резани .However, the work of the machine, equipped with this working body, is accompanied by high dynamic loads due to frontal cutting.

Цель изобретени - уменьщение энергоемкости и динамических нагрузок.The purpose of the invention is to reduce energy intensity and dynamic loads.

Поставленна цель достигаетс тем, что в рабочем органе режуща кромка планки расположена под углом к режущей кромке другой планки в плоскости, параллельной продольной оси фрезы, причем планки попарно соединены между собой.The goal is achieved by the fact that in the working body the cutting edge of the bar is at an angle to the cutting edge of the other bar in a plane parallel to the longitudinal axis of the cutter, the bars are interconnected in pairs.

Такое расположение ножей замен ет лобовое резание на косое, что обеспечивает снижение удельной энергоемкости процесса фрезеровани и динамические нагрузки, а также повышает надежность и долговечность всей машины в целом. Кроме того, расположение крайних точек режущих клиньев равноудалено от центральной оси фрезы и дает возможность примен ть ножи с пр 10 мой режущей кромкой. При прохождении таких режущих элементов мимо противорежущего ножа обеспечиваетс минимальный заданный зазор между режущими ножами и отбойным ножом.This arrangement of knives replaces frontal cutting on an oblique, which ensures a reduction in the specific energy consumption of the milling process and dynamic loads, as well as increases the reliability and durability of the whole machine. In addition, the location of the extreme points of the cutting wedges is equidistant from the central axis of the cutter and makes it possible to use knives with a straight cutting edge. When such cutting elements pass by the shear blade, a minimum specified clearance is provided between the cutting blades and the fire knife.

Claims

The working body includes a frame I, on the torus there is a baffle plate 2 with a shear knife 3, an onboard gear 4 and a milling cutter 5. The milling cutter has a body in the form of shaped figured disks 6, connected along the periphery by massive bars 7 displaced from both sides of each disk relative to each other at a certain angle. The slats are made in the form of a double trihedral wedge, at the base of the lateral edges of which flat knives 8 with cutting edges are installed. The end plates 9 rest on a ring 10 which concentrically surrounds the drive gear 11 connected through the shaft 12 to the bearing disk 13. The number of supporting disks and connecting bars forming a series of sections determines the width of the milling cutter. The cutting edges of the slats are angled to each other in the same plane. The required distance between the supporting discs and the angle of installation of the side faces of the double trihedral wedge is chosen so that the sections do not clog with plant debris and soil, as well as from the condition of admission to the gap between the shearing knife and the slats. The plane in which the slats are located is parallel to the longitudinal axis of the cutter. The set of knives on the cutter can be carried out along a helix, herringbone, or other scheme that is most rational for the execution of the technological process. Straps are pairwise connected to each other. The working body works as follows. When rotating from the tractor's power take-off shaft through the transmission, the onboard gearbox 4 and the gearbox 11 of the cutter through the shaft 12 connected to the bearing disk 13, the rotation is transmitted to the mill 5. The ring 10 concentrically covering the drive gearbox creates additional support for the end strips 9, the most reliable in the work of the extreme knives. Milling machines in the process of work puts woody vegetation on the soil. The counter knife 3 presses woody vegetation to the soil, and the mill 5, which is buried in the ground, rotates with knives 8, mills the soil together with the wood. The ground mass is thrown back and rolled on the rear roller. When milling, the knife 3 mounted on the baffle plate and the knives 8 of the cutter are two halves of scissors between which the wood vegetation is cut. The proposed tool body with skewed blades can significantly reduce the dynamic loads on the transmission of the machine, as well as reduce the energy intensity of the milling process. Claims The working body of a milling machine, comprising a body in the form of discs, fastened with strips, having cutting edges and forming a milling cutter with a longitudinal axis, and a counter knife, characterized in that, in order to reduce energy intensity and dynamic loads, the cutting edge of each slat angle to the cutting edge of the other plank in a plane parallel to the longitudinal axis of the cutter, and the strips are pairwise interconnected.
