Description

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 in the conditions of compacted, cohesive, highly 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, publ. 09/27/2010, bull. No. 27).

However, this forest fire dredger does not provide enough soil when extinguishing a fire on dense, bound, high-grained soil.

The closest in technical essence and the achieved result is a fire strip-spreading soil-throwing machine consisting of a frame, an attachment, two spherical disks (instead of spherical disks there can be plow-dump bodies - one left-handed, the other right-handed), milling thrower, cardan drive, transmissions with a safety device, a guiding casing, a gear-reverse (RF Patent No. 2496540, IPC A62C 27/00, publ. 10.27.2013, bull. No. 30).

However, like the analogue, it has disadvantages. In the case when the mechanism of formation of the soil shaft is made in the form of two spherical disks, then in the conditions of highly grained soils densely covered with grassy vegetation and saturated with tree roots, the disks are not deepened deep enough. As a result, shafts from loosened soil, shifted to the center of the passage of the unit, are formed of a small size, so the milling thrower does not have enough soil and it works idle. If the mechanism of shaft formation from loosened soil is made in the form of two plow-pile dumping hulls, then during the operation of these hulls it “broke” on dense, highly-grounded soils, dense layers and clods of earth bonded by roots and stems. It also reduces the effect of the milling thrower-thrower, as the soil is not sprayed, but flies in clods.

The utility model solves the problem of increasing the efficiency of a fire milling ground thrower under compacted, cohesive, high-pound conditions covered with small trees and shrubs and saturated with roots or a small amount of chopping residues.

The solution of the technical problem is achieved by the fact that the fire milling ground thrower contains a frame, a cardan drive, guiding guards, milling throwers. The difference from the prototype is that in front of the milling throwers, a milling drum with L-shaped knives and a cardan drive from the tractor power take-off shaft is mounted on the frame under the protective cover, and a height-adjustable support ski is located between the milling drum and milling throwers, and milling throwers are driven by a hydraulic motor through a safety device.

In FIG. 1 shows a general view of the milling fire extinguisher, in FIG. 2 is a flow chart of the operation of the soil thrower while loosening the soil strip and throwing the soil from this strip to the side of the fire.

The fire 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, two hydraulic motors 6 with safety devices 7, two milling throwers 8, two guide casings 9 and supporting ski 10, adjustable in height.

Milling fire extinguisher works as follows. When the tractor power take-off shaft is turned on, the torque from the engine is transmitted to the cardan shaft 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, etc.). With the translational movement of the unit, the milling drum 4, covered from above by the protective casing 5, rotates and the L-shaped knives milling the soil, forming after themselves a loosened strip of soil. Next, two milling cutter 8, located laterally on the frame 1, each rotate from their hydraulic motor 6 through a safety device (clutch) 7. The hydraulic motors 6 are driven from the tractor hydraulic system. Rotating, the milling throwers 8 capture the loosened soil and throw it on two guides of the casing 9 located above the milling throwers 8 at a certain angle. Further, the soil bounces from the covers 9 and scatters on both sides of the soil thrower. The distance over which the soil is discarded is regulated by the guiding casings 9, by raising or lowering them by means of hydraulic cylinders. When driving a ground thrower, a fire milling relies on a ski 10, which slides over the surface of the soil. To change the depth of milling by the milling drum 4, the support ski support 10 is telescopic. Height adjustment is carried out using bolts and vertically located holes on the support ski rack.

Due to the presence of a rotating milling drum with L-shaped knives in the soil thrower design, which preliminarily crush dense and heavily sodden soil, the work of milling throwers is facilitated, the amount of soil supplied by them to the fire zone increases, the uniformity of the distribution of soil and the range of its flight increase. The effectiveness of the fight against fire is also increased by increasing the translational speed of the unit and its patency in conditions of soils saturated with roots and cutting residues, as well as overgrown with low tree-shrub vegetation.

When laying mineralized fire strips, only the milling cutter works (the hydraulic motors are turned off) and the fire milling soil grinder is used as a strip layer.

When extinguishing the edge of ground fires, the milling drum and milling throwers rotate at the same time, which knock down the flame with a stream of flying soil.

The design of the proposed utility model of the fire mill milling gage is universal, as it helps to increase the efficiency of the gage in compacted, cohesive, highly-grounded soils overgrown with fine woody-shrubby vegetation and saturated with roots or a small amount of chopping residues. At the same time, the soil thrower can be used to prevent and extinguish bottom fires, as well as for strip preparation of soil for forest crops in clearings, burnt areas, heavily regrown, dense soils, overgrown with low shrubs.
