Description

The invention relates to machines for laying fire-fighting mineralized strips and extinguishing grassland forest fires with soil.

Known working body of a ground gun (USSR AS No. 631603, E023F 3/24, B65G 31/04), including a body, side support rollers, a cutter-thrower, a guide casing, a transmission with a safety device.

However, this working body does not sufficiently supply soil to the fire zone for extinguishing it when working on dense and cohesive soils that have roots in their composition.

Known fire-fighting ground gun-striping machine (RF patent No. 2496540 C1 A62C 27/00), including a frame, two spherical discs to form a shaft from loosened soil, a cutter-thrower, its drive and a hitch mechanism.

However, in this analogue, as in other structures, the soil is fed into the fire zone together with the top cover.

Known ground gun, the working body of which is made with symmetrically located on the shaft alternating cutting and throwing knives, and in front of the working body on the suspension bracket is mounted a thrust gear (AS No. 244204, SU, MKI B01d 3/02).

The disadvantage of the known device is that when cutting the soil, its working body has a high energy consumption.

Known ground-throwing machine for extinguishing ground fires, containing a frame carrying milling drums, actuators for controlling the working bodies, a guide casing, a soil throwing mechanism made with blades symmetrical in shape, hinged on a common hub (AS No. 277610, SU, MKI E02F3 / 18).

The disadvantages of the known device are high energy consumption, as well as low efficiency of the working body.

Known frontal forest fire ground gun, including a working body with knives-throwers, designed as a section of the spiral "wand", a mechanism for throwing soil, a control drive of 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).

However, this frontal forest fire-fighting ground gun requires aggregation with the base machine, the working body is not deepened enough in dense cohesive soils, and in order to increase the volume of soil supplied to the combustion zone, an increase in the number of parallel passes is actually required.

The closest in technical essence and the achieved result is (patent No. 2541987, E02F3 / 18), a fire-fighting ground gun-strip laying machine containing a frame, left and right augers located on the same axis of rotation, a loosening duckfoot paw, two milling throwers installed with one offset relative to the other in the longitudinal direction, the mechanism for turning the cutter-throwers in the horizontal plane, consisting of a vertical swivel stand and an external hydraulic cylinder, a hydraulic drive of the cutter-throwers and a mechanical drive of the augers from the tractor PTO shaft, shields of soil guides towards the edge of the fire at a variable angle to the direction of movement of the unit fuse for the duckfoot paw of the soil ripper when it encounters an obstacle and two spherical discs for the formation of micro-elevations in the area of action of the cutter-throwers.

The technical result is to simplify the design and increase the efficiency of ground throwing.

The technical result is achieved by the fact that a bevel gearbox with four output shafts is mounted on the frame of the device from below, while rippers are installed on two of them in the longitudinal direction, a moldboard cutter is installed on the third shaft, and a cutter-thrower is installed on the fourth shaft, and the gearbox is connected by clutches with a power plant located in the upper part of the frame, and in front of the frame there is a wheel in the travel stop with the possibility of changing the position in the vertical plane, while at the rear the body is connected to a U-shaped power stop, on the side racks of which there are adjusting units connected to the cross member , which has the ability to change its position in the vertical plane.

Figure 1 shows a general view of the gun (side view in working position); figure 2 is a general view (side transport position); figure 3 is a front view; figure 4 is a section.

The proposed invention consists of a frame 1 at the bottom of which a bevel gearbox 2 is mounted with four output shafts 3,4,5,6, while on two of them 3 and 4 there are cutters, rippers 7 and 8 in the longitudinal direction, on the third shaft 5, a moldboard cutter is installed 9, and on the fourth shaft 6 a cutter-thrower 10, and the gearbox is connected by means of a clutch 11 with a power plant 12 located in the upper part of the frame, and in front of the frame there is a wheel 13 in the travel stop 14 with the possibility of changing the position in the vertical plane, while at the rear the body is connected to the U-shaped power stop 15, on the side racks of which there are adjusting units 16 connected to the cross member 17, which has the ability to change its position in the vertical plane.

The device works as follows. Before starting work, it is necessary to move the unit to the working position. In this case, in the travel stop 14, the wheel fork 13 must be set in the upper position and fixed. Then turn the body to a horizontal position (Fig. 1).

After turning on the power plant 12, the milling cutters 7 and 8 are activated, respectively, and the moldboard cutter 9 is in front. This loosens the soil, and also due to the cutters of the rippers 7 and 8, the unit moves forward.

With the forward movement of the unit, the following milling cutter-thrower 10 captures and throws the loosened soil aside in order to form a mineralized fire strip.

Thus, the design of the proposed machine increases not only the forward speed of the unit and its productivity, but also increases the efficiency of work, covering the edge of the fire with soil.
