Abstract

FIELD: fire safety.

SUBSTANCE: casing ripper is rigidly fixed on the frame to protect the cutter-thrower from the hitting the obstacles and preliminary ground loosening, equipped with two windows for the ground ejection, and there are three cuttings knifes installed at the obtuse angle to the entry into the soil.

EFFECT: improved reliability due to the protection of the cutting working body from hitting the obstacle, efficiency increase of the work with the soil full of trees and shrubs roots, and the compacted cohesive soils, reduction of the weight and size of the machine.

Description

The invention relates to devices for the prevention and extinguishing of ground forest fires with soil.

Known milling strip-laying machine PF-1, consisting of a housing, a driveshaft, an attachment, a transfer gear, a transmission mechanism, a protective casing, a working body, a safety clutch and a support roller. It is intended for the creation and preparation of wide fire barriers as a measure to prevent the spread of fire, as well as in the direct fight against forest fires (AS USSR No. 3332179, E02F 5/08, E02F 3/18, publ. 03/14/1972, Bulletin No. 10).

The disadvantage of the milling strip sizing machine PF-1 is that it works only on light soils (sandy and sandy loam), on medium and heavy soils, the milling cutters are deepened to a shallow depth and the soil is supplied in insufficient quantity to ensure effective fire fighting.

The closest technical solution adopted for the prototype is a fire primer-strip stripper, including a frame, two spherical disks for forming a shaft from loosened soil, a milling thrower, guide plates for soil flow, a drive and a linkage mechanism. It is designed to extinguish ground fires with soil, as well as for laying protective mineralized strips (RF patent No. 2496540 C1 A62C 27/00, published on 10.27.2013, bull. No. 30).

The disadvantage of a fire-extinguishing strip stripper is its insufficient efficiency, due to the fact that the gearbox located in front of the thrower-mill limits access to it and thereby reduces the productivity of the machine as a whole. In addition, the milling thrower is not protected from below from hitting obstacles in the form of stumps and roots, which reduces reliability. Also disadvantages are the large dimensions and weight, due to the sequential arrangement of the milling cutter-thrower and spherical disks.

The invention solves the problem of increasing reliability, improving operating efficiency in conditions of soils saturated with roots of trees and shrubs and compacted cohesive soils, reducing the weight and dimensions of the machine, due to the fact that the casing-ripper is rigidly fixed to the frame to protect the milling thrower from impacts obstacles and preliminary loosening of the soil, equipped with two windows for ejecting the soil, and three cuttings are installed at an obtuse angle of entry into the soil.

Protection of the milling working body is achieved due to the fact that it is placed inside the casing-ripper, which covers the milling working body from below and prevents impacts from obstacles in the form of stumps and roots. The increase in work efficiency is achieved due to preliminary loosening of the soil with a casing-ripper and cutting of small roots with three knives mounted on it. Also, the knives prevent large roots and stumps from getting to the milling working body due to the fact that, relying on them, a forest fire soil-throwing machine is able to crawl onto obstacles that the knives cannot cut. Also, an increase in efficiency is achieved due to the fact that, unlike the prototype, soil access to the milling working body is not closed by the gearbox, since the drive is not placed in front of the working body, but behind it. The reduction in weight and dimensions is achieved due to the absence of spherical disks located in front of the working body.

In FIG. 1 shows a structural diagram of a forest fire soil-throwing machine; in FIG. 2 - a general view of a forest fire soil-throwing machine is presented.

The fire-fighting soil-throwing machine consists of a frame with a hinged mechanism 1, a milling working element 2 with a drive from a hydraulic motor 3, a casing-ripper 4, knives 5, guide plates for soil flow 6.

Forest fire soil-throwing machine operates as follows. When the tractor begins to move with a forest fire-fighting soil-throwing machine mounted on the rear linkage, the hydraulic motor 3 rotates the milling working element 2, the casing-ripper 4 along with the knives 5 goes into the ground, loosens it and cuts small roots. Then the loosened soil enters the milling working body 2 and is thrown out through the window. The ejection range of the soil is adjusted by changing the slope of the plate guiding the soil 6, and by changing the speed of the milling working body.

Thus, the design of the proposed machine can increase its reliability by protecting the milling working body from impacts on obstacles, as well as increase the efficiency of the unit in conditions of soils saturated with roots of trees and shrubs, and compacted cohesive soils, reducing the weight and size of the machine.
