The invention relates to a device for milling peat deposits, in particular for milling drums used in the peat industry.The famous mill, consisting of a frame with front and rear track rollers, through which the power cylinder is mounted cutter in the form of a drum, the surface of which Rattray posted by roll forming apparatus.with. 1689628, CL E 21 49/00, 1991).The lack of a router is low productivity due to the design of the cutting element.The closest prototype to the technical essence is a mill, consisting of a frame with the front roller, on which by means of a power cylinder mounted on the cutter drum which is equipped with work items, arranged along a helical line, is made circular in form of a truncated cone with a flat working surface having a height from the top equal to the sum of the diameters of the base and the apex of the cone associated with the control mechanism of relief of deposits, including triplici levers and force the cylinder body pivotally connected with the frame and with the specified tripletime levers and rod - mill, behind which is attached to the frame roll forming machine (and.with. 2119058, CL E 21 49/00, 1998 ).The disadvantage of this mill is slow performance when milling horse peat deposits a low degree of decomposition is less than 25% due to the constructive design of the work item.The objective of the invention is the creation of highly efficient and reliable devices.The technical result - increasing anyh types of deposits in a wide range according to the degree of decomposition and humidity.The technical result is achieved by the fact that the milling cutter, comprising a frame with a support roller, the cutter with the work items in the form of a circular truncated cone with a flat working surface, the control mechanism of relief of the surface deposits, power cylinders, according to the invention in the working elements are additionally made the working surface in the form of a wedge, the length of the wedge is equal to the length of the work area of the element and the top of the wedge is located opposite to the flat working surface.The proposed mill is illustrated by drawings, where:
in Fig.1 - Fraser, side view;
in Fig.2 - shows the work item type on a flat surface;
in Fig.3 - shows the position of the wedge in the working portion of the element cross-section view of B in Fig.2;
in Fig.4 - shows the work item view of the wedge-shaped surface;
in Fig.5 is a cross section along b-b In Fig.2;
in Fig.6 is a cross-section along G-G in Fig.4.The mill includes a frame 1. Support roller 2 is attached to the side brackets of the front frame 1. The control mechanism of relief of the surface peat deposits has two triplici lever 3, two rollers 4, the ends of the axis which rely on bearings, zadanie oblong hole 6, performed on the lower arm of each lever 3. Two power cylinder 7 of the hinge housing connected to the lugs of the upper arm of the lever 3, and a rod connected with the bracket hub cutters 5. Two power cylinder 8 of the hinge housing connected to the frame 1 and the shaft to the third arm of the lever 3. The casing 9 is equidistant the circumference of the drum cutters 5 and connected with the side walls of the frame 1. On the surface of the drum cutters 5 are arranged along a helical line working element 10, is made circular in form of a truncated cone with a flat working surface 11, the height H which is equal to the sum of the diameters of the upper base and the apex of the cone, i.e., N1=D1+ D2counting from the top of the cone. On each working element 10, on the opposite side of the flat surface 11, additionally made in the form of a wedge surface 12 with a cutting edge 13, the height H2which is equal to the length L of the work area item 10.The router works as follows.To work on peat medium and high degree of decomposition of the flat surface 11 of the working elements 10 installed in the direction of rotation of the drum cutters 5. Then sets the desired milling depth of the Deposit. This si replica levers 3 are rotated by the rods of the buildings of the frame 1. The power cylinder 7 moves the cutter 5 so that work items 10 solubility in the surface at the desired milling depth of the Deposit. Fixing the position of the cutter 5 in the slots 6 of the levers 3, the rods of the power cylinders 8 disconnect from shoulder levers 3.When the movement of the milling cutter in the direction of arrow A (Fig.1) rink 2 tramples down the surface deposits and compacts it. The rollers 4 describe the topography of the surface deposits and transfers the information directly to the cutter 5, which cuts the specified layer deposits. While working elements 10 cut into the peat, and their flat work surface 11 is in contact with enough of its area and like the shovel begrebet peat deposits from. Peat, taken working elements 10 is emitted to the surface of the Deposit and spread loose layer with a particle size in cross-section adopted for the milling depth of about 105 mmWhen included in the design of the mill roll forming apparatus.with. 2119058,1991 ). peat after compression is removed from the grooves shaped roll in the form of enlarged molded particles and spread evenly on preservando surface, thereby significantly reducing the duration of drying, and then bringing the raw peat marketable.Performing at the working surface elements in the form of a wedge ensures stable performance on peat with a low degree of decomposition.Wedge-shaped surface significantly reduces energy consumption of the milling process due to consistent effects on peat deposits.Execution on a work item flat and wedge-shaped surfaces allows to process deposits in a wide range as the level of decomposition, and humidity.The proposed mill is made of standard parts and easily implemented in industry, and small repair shops. The mill, including the mi elements, the control mechanism of relief of the surface deposits, power cylinders, characterized in that the operating elements are additionally made the working surface in the form of a wedge, the length of the wedge is equal to the length of the work area of the element and the top of the wedge is located opposite to the flat working surface.
