Abstract

FIELD: fire-extinguish.

SUBSTANCE: invention relates to devices designed to extinguish ground fires with soil, as well as for laying protective mineralized strips. The effect is achieved by the fact that the forest fire soil thrower, containing a frame, cutters-throwers, a drive, according to the invention, it contains a frame, in the rear part of which a working body is pivotally mounted in the form of a high-torque hydraulic motor with a flywheel mounted on its output shaft with cutters-throwers, and the body the hydraulic motor in the upper part is connected to the frame by means of a hydraulic cylinder with the possibility of changing the position in the vertical plane. The proposed device makes it universal, as it is both a soil thrower and a strip-laying device, it has the ability to regulate the supply of the amount of soil supplied to extinguish the fire, as well as to regulate the forward speed of the tractor and, consequently, its productivity.

EFFECT: simplification of the design of a forest fire soil thrower with high efficiency in soils saturated with roots.

Description

The invention relates to devices designed to extinguish ground fires with soil, as well as for laying protective mineralized strips.

Known working body of an earth-moving - throwing machine, including a body, side track rollers with stabilizing flanges, a milling cutter, a guide casing, a transmission with a safety device (AS USSR No. 631603, E02F 3/24, B65G 31/04, publ. 11/05/1978, bulletin No. 41).

The main disadvantage is that the soil is supplied in insufficient quantities to the fire zone.

A technical solution is known, including a working body with throwers made in the form of spiral knives, a soil throwing mechanism, a drive for controlling the working body mounted on the swing axis, placed beyond its center of mass (RF patent No. 2400274, A62C 27/00, B65G 31/04 , E02F 3/18, published 09/27/2010).

In analog, the working body-thrower is not deep enough in conditions of dense cohesive soils saturated with tree roots, which reduces the effect of the soil thrower.

The closest in technical essence is a technical solution (patent No. 2762160) containing a frame with a hinge mechanism, an auger with radial teeth and driven by a hydraulic motor, spherical discs with a removable cutting edge with semicircular cutouts, with safety tension springs and driven by hydraulic motors, cutters - Throwers driven by hydraulic motors, housing guides, track rollers. The auger is mounted on the frame by means of racks with a movable connection, while a damping spring is installed between the frame and the auger with the ability to control the compression force and pressure of the auger on the support surface, and the force on the damping spring does not exceed the limiting circumferential force at the ends of the radial teeth of the auger developed by the hydraulic motor at rolling the auger over an obstacle.

The main disadvantage is the bulky design.

The technical result is a simplification of the design of a forest fire soil thrower with high efficiency in soils saturated with roots.

The technical result is achieved by the fact that the forest fire ground thrower, containing a frame, cutters-throwers, a drive, according to the invention, it contains a frame, in the rear part of which a working body is pivotally mounted in the form of a high-torque hydraulic motor with a flywheel mounted on its output shaft with cutters-throwers, and the hydraulic motor housing in the upper part is connected to the frame by means of a hydraulic cylinder with the possibility of changing the position in the vertical plane.

Figure 1 shows a General view of the forest fire soil thrower; figure 2 - side view in the transport position; figure 3 side view in the working position; fig. 4 - top view of the forest fire soil thrower; fig. 5 - flywheel with milling cutters.

The forest fire soil thrower contains a frame 1, in the rear part of which the working body is pivotally mounted in the form of a high-torque hydraulic motor 2 with a flywheel 4 mounted on its output shaft 3 with milling cutters 5, and the body of the hydraulic motor 2 in the upper part by means of a hydraulic cylinder 6 is connected to the frame 1 with the possibility position changes in the vertical plane.

Forest fire soil thrower works as follows. When the hydraulic drive of the tractor 7 is turned on, the pressure from the pump 8 is transferred to the hydraulic motor 2, while the flywheel 4 spins up, accumulating energy. Then, by means of the hydraulic cylinder 6, the hydraulic motor 2 with cutters - throwers 5 is transferred to a vertical position. With the translational movement of the tractor 7, the flywheel 4 is buried in the soil and ejects a sufficient amount of the mass of the supplied soil into the fire zone.

Depending on the density of the soil, the depth of the flywheel is controlled by a hydraulic cylinder. The proposed device makes it universal because it is both a soil thrower and a strip-laying device. It has the ability to regulate the amount of soil supplied to extinguish a fire, as well as to regulate the forward speed of the tractor and, consequently, its productivity.
