Description

one

The invention relates to machines for the development of peat deposits and landfill lands.

A known soil treatment machine including milling drums with knives, a frame with a baffle plate, front and rear support rollers, drive and lift mechanisms and a cam separator.

However, this machine does not provide effective development of soil that has significant viscosity.

The purpose of the invention is to increase the efficiency of soil development. For this, in the cam separator a scrubber in the form of a comb is installed with the possibility of reciprocating motion.

FIG. 1 depicts the described maschina, general view; in fig. 2 - milling drum with knives; in fig. 3 is a diagram of the arrangement of knives on the drum in plan; in fig. 4 - cam separator and cleaner in the section; in fig. 5 - the same, side view.

The soil treatment machine includes a milling drum 1 with segment blades 2, a frame 3 with a baffle plate 4, front 5 and rear 6 track rollers, drive mechanisms 7 and lifting 8, and a cam separator 9 with rollers 10 mounted at an angle to the horizontal. Ellipsoid welded to rollers

cams //. In the cam separator, the scrubber 12, designed as a comb, is installed with the possibility of reciprocating movement. To gearbox housings

drive 7 of separator 9, guides 13 are welded. Combi-cleaner 12 is attached to two carriages 14, rollers 15 of which are included in guides 13. A traction chain 16 is connected to the carriages. The drive 17 mechanism of reciprocating movement of the purifier 12 is double-acting , spur gear and chain gears. The work of the maschina is carried out as follows.

in a way.

As it moves forward, the rotating milling drum / sinks into the ground and processes it along with woody inclusions, hummocks and vegetation. The milled mass rises with segmented knives 2 and is thrown off by a uniform flow to the separator 9, where the separation of peat or mineral soil from wood inclusions occurs. The particles of peat or mineral soil are sifted through the holes of the separator to the bottom of the formed trench, and the wood inclusions are rotating in one direction by elliptical cams 11 moving along the separator and

dumped into the body or conveyor.

In the course of the operation, peat or mineral soil with residues of wood inclusions adheres to the rollers 10 and separator cams and the rod is wound. As a result, the holes formed by the cams // and the separator rollers 10 are reduced, this drastically reduces the screening capacity of the separator, and consequently, degrades the quality of its operation. To remove sticking soil or peat and wound Prutievs use a comb numerator 12, which, moving back and forth on the rollers 15 in the direction of yush; 13, passes the teeth of the comb between the cams 11, cleans the cams and rollers 10. The cleaner is carried out using a double-acting hydraulic cylinder, to the stem of which a gear rack is connected (conventionally not shown in the drawing).

By supplying oil to one or the other cavity of the cylinder, a rod with a rod is moved. Moving, the rail rotates the cylindrical gear of the gearbox, from which the rotation is transmitted by means of chain gears to the pull chain 16 attached to the carriages 14, and moves along the separator 9 a ridge cleaner 12, the tooth of which passes under the rollers 10 5 between the cams 11.

As a result of cleaning the cams and rollers produced without stopping the machine, the sifting capacity of the separator is restored, which allows expanding the field of application and improving the quality of operation of milling machines equipped with separators.
