Abstract

FIELD: fire-fighting facilities.

SUBSTANCE: invention relates to devices intended to extinguish ground fires with soil, as well as for the construction of protective mineralised bands. Fire-extinguishing soil-thrower-fire-break maker comprises a frame, a working body with cutter-thrower, a drive, a guiding casing, a transmission with a safety device and a hinge mechanism. Fire-extinguishing soil-thrower-fire-break maker has mounted on the frame in front of the cutter-thrower the mechanism of embankment formation of the loosened soil. The mechanism of embankment formation can be made in the form of two concave discs or in the form of two ploughshare-dump bodies. The discs for cutting soil layers and their sliding to the center of the device aisle. The discs are connected to the frame with the ability of changing the distance between them and rearrangement for operation according to the scheme "through and through".

EFFECT: invention solves the problem of creation of a fire-extinguishing soil-thrower with high operational performance in conditions of soil rich with roots of trees and shrubs and compacted coherent soils, as well as acting as a fire-break maker.

Description

The invention relates to devices for extinguishing ground fires with soil, as well as for laying protective mineralized strips, especially in anhydrous massifs.

Known working body earthmoving - throwing machine, comprising a housing, side track rollers with stabilizing flanges, milling thrower, guiding casing, transmission with a safety device (AS USSR No. 631603, E02F 3/24, B65G 31/04, publ. 11/05/1978, bull. No. 41).

However, this working body does not sufficiently supply soil to the fire zone to extinguish it when working on dense bound soil.

The closest in technical essence and the achieved result is a frontal forest fire gage, including a working body with throwers made in the form of spiral knives, a soil throwing mechanism, a control drive for the working body mounted on the swing axis, issued for its center of mass (RF patent No. 2400274, A62C 27/00, B65G 31/04, E02F 3/18, publ. 09/27/2010).

However, as in the analogue, the working thrower is not deep enough in the conditions of dense cohesive soils saturated with tree roots, which reduces the effect of the soil thrower. In addition, all soil-throwing machines are characterized by the lack of versatility that does not allow the laying of fire strips, as a preventive fire-fighting measure, which allows to reduce the fleet of different-sized machines and reduce operating costs.

The invention solves the problem of creating a fire primer with high efficiency in conditions of soils saturated with roots of trees and shrubs and compacted cohesive soils, as well as performing the function of a strip pavement.

This is achieved by the fact that the fire strip-spreading soil-throwing machine containing a frame, a working body with a milling thrower, a drive, a guiding casing, a transmission with a safety device and a hitch mechanism according to the invention further comprises a shaft forming mechanism from a loosened soil on the frame in front of the milling thrower . The mechanism of shaft formation from loosened soil is made in the form of two spherical disks for cutting soil layers and shifting them to the center of the passage of the unit, connected to the frame with the possibility of changing the distance between them and rearranging to work according to the “wrecked” scheme. Also, the mechanism of the shaft formation from loosened soil can be made in the form of two ploughshare-dump bodies connected to the frame with the possibility of changing the distance between them and rearranging to work according to the “wrecked” scheme.

Figure 1 presents a General view of the soil-throwing strip;

figure 2 is a flow chart of the operation of the machine in a variant of the simultaneous formation of a shaft of loose soil and its throwing in the direction of fire; figure 3 is a flow chart of the operation of the machine as a strip-plotter.

The strip thrower is composed of a frame 1, an attachment 2, two spherical disks 3, a milling thrower 4, a cardan drive 5, a transmission with a safety device 6, a guiding casing 7, a gear-reverse 8. Instead of spherical disks, a plow blade can be installed buildings, one of which is left-handed, and the second is right-handed.

The ground-strip stripper works as follows. When the tractor’s power take-off shaft is turned on, the torque from the engine is transmitted to the cardan drive 5 and the reverse gear 8 to the transmission 6 to the milling cutter 4. During translational movement of the unit, spherical disks or ploughshaft-dump bodies are buried in the soil, cut the seams and shift them to the center forming a soil-soil shaft in a loosened state, thereby facilitating the process of cutting soil with a milling thrower, reduce energy costs for milling and increase the volume of the mass of soil supplied to the fire zone. Following the milling thrower, it grabs the soil from the shaft and partially below the shaft and throws it into the fire zone.

For laying fire-resistant mineralized strips as a preliminary preventive measure, disks or ploughshare-dump casings are rearranged to operate according to the “collapsed” scheme, the milling thrower is turned off during strip laying.

Thus, the design of the proposed machine makes it universal, which is both a soil thrower and a strip spreader, replacing at least two modern machines and thereby reducing the material consumption of the fire extinguishing process and laying fire strips; increases the amount of soil supplied to extinguish the fire, increasing efficiency in the fight against fire, as well as the translational speed of the unit and, therefore, its productivity.
