Description

The known machines for milling the peat deposit, processing and molding, milled peat using two rotating drums of the forming drums, due to insufficient plasticity of the milled peat, do not ensure its high-quality forming.

In the proposed machine, in order to increase the plasticity of the milled peat, a device made in the form of a shield, enveloping a part of the cutters of the drum, was used.

During the passage between the milling cutter knives and the shield, milled peat receives additional processing by grinding peat on peat and against the wall of the shield.

FIG. 1 shows a schematic side view of the machine; in fig. 2 - the same car in the plan.

The machine, made in the form of a trailer, has a milling cutter /, whose axles are supported on bearings 2, embedded in the side walls 3 of the cutter casing. In addition to the side walls, the casing 4 of the cutter is formed from a solid curved sheet. Drove 5 is attached to the cutter casing through the box 6, creating the necessary rigidity as the entire casing, and its side walls. The carrier is connected to the tractor through the hinge 7. The cutter casing rests on the surface of the peat massif through the bashmak 8. Strips of square section welded into the grooves made in the side walls 3 and which can be moved along these grooves are welded to the end walls of the milling cutter. screw 10. By moving the shoe up and down it is possible to change the thickness of the milling layer.

Concentric to the cutter axis, there is a shield // so that between the surface of this shield and the surface described by the cutter blades, there is a gap that can be changed depending on the installation of the shield. You can also change the shield // change it

shchirinu.

When the machine moves in the direction of the arrow L and simultaneously rotates the cutter in arrow B, the milled peat mass with the cutter knives is carried along the shield // and is ejected over the cutter.

No. 86683-2. Under the action of centrifugal force, the milled mass moves along the shield and presses against it, resulting in the rubbing of peat, which increases its plasticity. To increase the degree of peat processing, the surface of the flap // can be made grooved. As a result of grinding the peat mass with a cutter knife and then grinding it while passing between the cutter knives and the shield, the peat processing becomes good, making it plastic, despite the low humidity of the milling layer. The rotation of the milling cutter is obtained from the engine of the tractor through a power take-off shaft connected to the telescopic shaft 15: rotating a conical bristle 16, which engages with two other such scissors mounted on shafts 17 and 18.

From shaft 18, rotation through a chain transmission is transmitted on the mill axis. From the shaft 17, one of the rollers 12 is rotated by means of a chain transmission, and the other roller is rotated from it through cylindrical gear 19.

The peat processed and milled out by the mill is guided by the wall of the casing 4 to the rotating rollers 12. In order to prevent the milled peat from spilling between the roller and the mill when the milling layer of the massif is large enough, a partition 13 is installed. The surface of the rollers can be smooth or have reefs or cells

Peat is captured by the rollers and pressed into pieces with a circular or lenticular cross section depending on the shape of the reefs.

If the axes of the rollers are installed with the possibility of moving apart, and if the rollers are pressed towards each other by springs 14 and the amount supplied to the peat rollers is larger than that required for a certain number of revolutions of the rollers, then the rollers are moved apart and corrugated plates are obtained instead of individual pieces of peat.

The milled and formed peat with the help of the described maschine falls on the surface of the massif and is arranged in a uniform layer. After drying, pieces of peat, the weight of which does not exceed one gram, are harvested from plants and put into caravans with the help of well-known cleaning machines used in the extraction of milled peat.

Subject invention

A machine for milling, processing and shaping peat with rollers that have springs, rifles, etc., using a shield that bends around a part of the milling drum for further processing of peat by rubbing it between the shield and the knives of the milling drum.
