The utility model relates to devices designed to prevent and extinguish ground fires by laying mineralized fire strips in anhydrous massifs in the conditions of high-grounded soils overgrown with dense grassy and small tree-shrub vegetation.

A well-known forest plow for slopes PLC-0.6 includes a two-blade body, a circular knife, a cultivating paw and a device for compressing the strata, consisting of two tapering press rollers and a pendulum-type mechanism for automatic rotation of the rollers (Forest Encyclopedia: 2 tons , vol. 2 / Ch.edited by G.I. Vorobyov; Edited by: Anuchin N.A., Atrokhin V.G., Vinogradov V.N. et al. - M .: Sov. encyclopedia, 1986. - 631 p.).

However, this forest plow does not crush the soil well enough and efficiently on dense, connected, highly-soiled soils overgrown with dense grassy and shrubby vegetation.

The closest in technical essence and the achieved result is a mounted plow-ripper PRN - 40, consisting of a frame, a linkage mechanism, a plow-blade body, a rotary cultivator, a deep-ripper, a support wheel with a screw mechanism for regulating the depth of soil preparation, a circular knife connected to the right supporting wheel, rotary cultivator drive mechanism, including gearbox, cardan and V-belt drives (I. Bartenev. Work processes and new technical means of tillage when growing protection forest stands on the slopes in the zone of insufficient and unstable humidification: dissertation for a co-registered student, Doctor of Technical Sciences, specialty 05.21.01 Technology and mechanization of forestry and logging. VNIALMI: Volgograd, 1983. - 449 s. .).

However, like the analogue, the mounted plow-ripper PRN-40 has disadvantages. When they lay mineralized fire strips and extinguish forest fires in spaces with high grassy vegetation and densely covered with bushes in one pass, an insufficiently wide treated strip is created. As a result, the fire jumps over the mineralized strip. In addition, the movement of the plow-ripper is hindered by coarse-stalked grass and dense shrubs.

The technical task of the utility model is to increase the efficiency of the fire-fighting brush-cutting plow in compacted, cohesive, high-grained soils overgrown with coarse-stalked grassy and dense tree-shrubbery vegetation.

The solution of the technical problem is achieved by the fact that the fire-fighting brush-cutting plow contains a frame, a drive, a single dump body, and a rotary cultivator. The difference from the prototype is that, on the opposite side of the rotary cultivator perpendicular to the frame, a cutting bar with disks (chopping knives) is installed, the drive of which is carried out from the hydraulic motor, and the height adjustment by the hydraulic cylinder.

In FIG. shows a general view of a fire-fighting brush-cutting plow. Fire-fighting brush-cutting plow consists of a single dump body - 1; gearbox - 2; rotary cultivator - 3; V-belt - 4; pulleys - 5; hydraulic motor - 6; hydraulic cylinder - 7; cutting beam - 8; cutting discs (chopping knives) - 9; support shoe - 10; support wheels - 11; intermediate shaft - 12; frames - 13; support rack - 14; propeller shaft - 15; automatic couplings - 16; circular knife - 17.

Plow-brushcutter fire works as follows. When the tractor’s power take-off shaft (PTO) is turned on, the torque from the engine is transmitted to the driveshaft 15 and through the intermediate shaft 12 to the gear 2. From the gear 2 through the V-belt 4, the torque is transmitted to the pulleys 5 and then to the shaft of the rotary cultivator 3, which starts to rotate . During the forward movement, the plow-brush cutter mounted on the rear linkage of the tractor by means of the automatic coupling 16 is supported by the support wheel 11. At this time, the circular knife 17 cuts the soil and the roots, roots and cutting residues located therein, protecting it from damage and facilitating the entry into the soil of the set followed by a single dump body 1. At the same time, a single dump body 1 raises the cut soil layer and directs it to a rotating rotary cultivator 3, which crumbles the soil with its blades and throws it to the side, forming after it loosened strip of soil. At the same time, on the horizontal cutter bar 8, located horizontally on the opposite side of the rotary cultivator 3, the cutting discs (chopping knives) 9 rotate. They cut grass and shrub vegetation and shift it to the side. The rotation of the disks (chopping knives) 9 is carried out from the hydraulic motor 6 through the shaft and safety devices (couplings). The hydraulic motor 6 is driven from the tractor hydraulic system. The rise in the transport, position, lowering to the working position and height adjustment of the cutting beam 8 is carried out by the tractor driver from the cab using the hydraulic cylinder 7, operating from the tractor hydraulic system. In the working position, the cutting beam 8 rests on the support shoe 10 and slides on the surface of the soil. All of the above parts of the fire-fighting brush-cutting plow are mounted on the frame 13. In order to prevent it from falling during maintenance and repair, the support posts 14 are used.

Due to the presence of a cutting beam with rotary disks (chopping knives) in the design of the fire-fighting brush-cutting plow, cutting and shifting to the side grassy and shrubby vegetation, its aggregation in areas with high grassy vegetation, dense shrubs, small undergrowth, and undergrowth is facilitated. In addition, the effectiveness of the fight against fire is increased by increasing the width of the mineralized strip cleared of combustible materials (grass, shrubs, undergrowth, etc.).

When extinguishing the edge of ground fires under a forest canopy or along protective forest stands, cutting discs (chopping knives) can work simultaneously with a rotary cultivator, and if necessary (difficult areas, lack of grass cover or shrubs), they can be switched off. In this case, the cutting bar rises, i.e. is transferred by a hydraulic cylinder to a vertical (transport) position.

The design of the proposed utility model of a fire-engine brush-cutting plow is universal, since it helps to increase the efficiency of the brush-cutting plow in compacted, highly-grained soils saturated with roots or a small amount of chopping residues, as well as overgrown with coarse grassy and dense tree-shrub vegetation (overgrown undergrowth, undergrowth).
