Description

The utility model relates to fire fighting equipment, namely to machines for laying fire mineralized strips and extinguishing ground forest fires with soil.

Known working body of the soil thrower (AS USSR No. 631603, IPC E02F 3/24, B65G 31/04, publ. 11/05/1978), comprising a housing, a rotor hub with cutting elements and throwing vanes mounted on it with connecting fingers, a fairing .

However, this working body cannot be used for laying mineralized fire strips and supplies insufficient soil volume to the bottom fire zone to extinguish it when working on dense and cohesive soil containing tree-shrub roots and grassy turf roots.

Known fire-fighting soil-throwing machine (RF patent No. 2616021, IPC E02F 3/18, publ. 04/12/2017), consisting of a frame with a mounted mechanism, a milling working body and a hydraulic motor. The machine is equipped with a cultivator casing having knives and guide plates for soil flow. When carrying out work to create mineralized fire strips or to extinguish the edge of a lower forest fire, a large amount of soil is unloaded on both sides of the casing-cultivator. The rest of the soil mass is fed to the guide plates in the form of a continuous tape, which affects the range and effectiveness of throwing soil. In addition, the machine is located on the rear linkage of the tractor, thereby impairing the maneuverability and maneuverability of the unit. Adopted as a prototype.

The utility model solves the problem of improving the quality and efficiency of creating fire-resistant mineralized strips, in particular, on dense and cohesive soil with a large number of wood inclusions and turf.

To achieve this goal, in a forest fire strip raiser containing a frame with a hinged mechanism, a milling working element, a cultivating pallet, which is a symmetrical welded structure, each half of which is separated by a vertical knife, and including a share, a working surface and walls, a hydraulic motor, according to the useful models, the working surface of the pallet-cultivator along which the cut-out soil layer moves is made in a curved semi-cylindrical shape, and h are placed in front of the implement tyre disc knife located hardly on the racks, which in the pan-ripper, there are special slots.

The technical solution is illustrated graphically, where in FIG. 1 shows a forest fire stripper (general view); in FIG. 2 - the same front view; in FIG. 3 - General view of the milling working body; in FIG. 4 - the working surface of the pallet-ripper.

A forest fire stripper is located on the front linkage of the tractor and contains a frame with an attachment mechanism 1, a pallet-ripper 2, a milling working element 3 driven by a hydraulic motor 4, and a vertical knife 5 with an obtuse angle of entry into the soil.

The milling working body has a casing 6, made in the form of a welded structure of sheet metal. In the process, the volume of soil thrown by the blades 14 thanks to it is directed into the stream, the throwing distance of which is regulated by the installation angle of the visor-guide 7, which is changed by the hydraulic cylinder 8.

The rotational movement of the milling working body 3 is provided due to the hydraulic motor 4 installed in the protective housing 9.

Four circular knives 10 are located at the front of the stripper, hardly located on the uprights 11, for which purpose there are special slots in the pallet-ripper 2.

Circular knives cut small plant roots and divide the soil layer into smaller fractions, thereby facilitating its further throwing by the blades of the 14 milling working body, which is important when working on dense and cohesive soil with a large amount of turf.

The depth of the forest fire stripper is limited to supporting skis 12.

The milling working body consists of a disk 13 on which three blades 14 are mounted for throwing soil by giving it kinetic energy. Additional crumbling of soil fragments is carried out by transverse knives 15.

The subsoiler 2 is a symmetrical welded structure, each half of which, separated by a vertical knife 5, includes a ploughshare 16, a curved semi-cylindrical working surface 17 and the wall 18.

This design of the working surface of the pallet-cultivator, made on the principle of a plough-dump surface of the plow body, avoids the removal of soil volumes on both sides of the implement and ensures the supply of the necessary amount of soil to the milling working body with minimal losses.

Placing a strip-laying machine on the front linkage of the tractor allows the operator to efficiently select the path of the implement, thereby laying a fire strip with a minimum of gaps.

Forest fire stripper works as follows.

The unit calls into the area where it is necessary to create a fire-resistant mineralized strip, the gun is installed in the working position. In the process of translational movement, the pallet-ripper is deepened by the required amount, limited by supporting skis, thereby forming the width of the fire-resistant mineralized strip.

Ahead, the walking circular knives divide the continuous strip of the soil layer then cut with a pallet-ripper into smaller fractions.

Further, the crushed soil volumes fall on the semi-cylindrical working surface of the pallet-cultivator, separated by a vertical knife for feeding to the working body from the left and right sides.

Moving along a curved working surface, the soil is delivered to the milling working body, where the blades pick it up and, by giving it kinetic energy, throw it in a directional direction, additionally creating a bed to be filled. By means of a protective casing, the soil volume is directed into the flow directionally, the operator can adjust the throwing distance from the tractor cab with the installed hydraulic cylinder.

In the event of encountering insurmountable obstacles, the strip spreader is deepened by lifting the tractor hitch.

The forest fire stripper can also be used to quickly localize the edge of the forest bottom fires and to promote the natural regeneration of the forest by mineralization of the soil.

The proposed design of the forest fire stripper allows to improve the quality and efficiency of the process of creating fire mineralized strips, including on dense and cohesive soil with a large number of wood inclusions and turf.
