RU191177U1 - Modified milling fire extinguisher - Google Patents

Abstract

The utility model relates to devices designed to extinguish ground fires by throwing soil, as well as to lay fire mineralized strips in anhydrous massifs, and solves the problem of increasing the efficiency of a fire milling modified mortar in conditions of compacted, cohesive, highly grained pounds, overgrown with small tree-shrub vegetation and saturated with roots or a small amount of chopping residues. The technical task of this utility model is to increase the efficiency of material feed from the milling cutters of the drum to the spreader blades. The solution to the technical problem is achieved by the fact that rotary blade devices are installed on the rear of the soil thrower frame, which capture and move to the periphery of the ground milled by the mill, forming micro-elevation bands along the edges.

Description

The design relates to devices designed to extinguish ground fires by throwing soil, as well as to lay fire mineralized strips in anhydrous massifs in the conditions of compacted, cohesive, high-grounded soils overgrown with fine woody-shrubby vegetation and saturated with roots or a small amount of chopping residues.

Known frontal forest fire dredger, 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, issued for its center of mass (RF patent No. 2400274, IPC A62C 27/00, B65G 31 / 04, E02F 3/18, published September 27, 2010, Bulletin No. 27). However, this forest fire dredger is not efficient enough to feed the soil when extinguishing fire on dense, bound, high-grounded soil.

The closest in design and method of work is a fire milling ground thrower, consisting of a frame with a hinged device, a cardan shaft, a gearbox, a milling drum with L-shaped knives, a protective casing, hydraulic motors, a safety device, milling throwers, guiding casings, a support ski , adjustable in height (RF patent No. 144715, IPC A62C 27/00, publ. 08/27/2014, bull. No. 24).

In the indicated design of the fire soil meter with a milling working body, the disadvantage is the low efficiency of material supply from the drum mills to the spreader blades, since the L-shaped knives cannot provide the necessary kinetic energy to the cut soil particles.

The technical task of this utility model is to increase the efficiency of material supply from the milling cutter of the drum to the blades of the spreader.

The solution to the technical problem is achieved by the fact that on the back of the frame of the soil thrower there are installed rotary blade devices that capture and move to the periphery of the ground crushed by the mill, forming micro-elevation bands along the edges.

In FIG. shows a general view of the modified milling fire extinguisher. The modified milling fire primer consists of a frame with a hinged device 1, a cardan shaft 2, a gearbox 3, a milling drum with L-shaped knives 4, a protective casing 5, a support ski 6, and a rotary blade device 7.

Modified fire extinguisher soil grinder works as follows. When the tractor power take-off shaft is turned on, the torque from the engine is transmitted to the driveshaft 2, through the gearbox 3, to the transmission of the milling drum 4, which starts to rotate. Milling drum 4 is a shaft with spherical disks freely mounted on it, to which L-shaped knives are attached around the circumference.

Between disks with L-shaped knives, rubber couplings are installed to prevent knife breakage when meeting with solid soil inclusions (stones, roots, stumps). With the translational movement of the unit, the milling drum, covered with a protective cover 5 from above, rotates and the L-shaped knives milling the soil, forming a loosened strip of soil after itself.

Rotary blade devices 7 installed in the rear of the frame of the soil thrower, capture and move to the periphery of the milled soil, forming along the edges of the micro-elevation strip.

To change the depth of tillage with a milling drum, the support ski rack 6 is telescopic. Height adjustment is carried out using bolts and vertically located holes on it.

The design of the proposed utility model of the fire milling modified milling gage is universal, since it helps to increase the efficiency of the gage in compacted, cohesive, high-grounded soils overgrown with fine woody-shrubby vegetation and saturated with roots or a small amount of chopping residues.
