Description

The invention was created to meet the vital needs of a person, intended for individual service and multifunctional use.

The wheeled unit (hereinafter - the unit) can be used as a mower, lawn mower, electric fan, motor fan and water jet propulsion.

An analogue is the device of a gasoline and electric lawn mower (see, for example, “New Polytechnical Dictionary” by A.Yu. Ishlinsky, p. 243, scientific publication “Big Russian Encyclopedia”, Moscow, 2003).

The analogue includes a case in the form of a stroller with four wheels and with a handle for driving and control. On the case there is a spiral (cochlear) casing with a suction hole at the bottom and an exhaust pipe on the side. In the casing is a cutting tool in the form of one or more knives with sharpened blades. A gasoline or electric engine is installed on the casing.

The analogue works as follows. Turn on the engine, which begins to rotate the knives of the cutting tool in a horizontal plane. When the lawnmower moves, knives close to the ground begin to cut (chop) the grass. The grass is dispersed inside the casing in a spiral and thrown through the exhaust pipe into the surrounding space.

Big advantages are gas mowers. They have high performance and extensive autonomy in their use.

A disadvantage of the analogue is its cutting tool. Knife blades, striking at the right angle against the trunks of hardened and especially wild grass, cut it with great difficulty and therefore often become dull and destroyed.

The disadvantage of the analogue is its narrow specialization, which allows you to work only as a lawn mower.

The disadvantage of the analogue is that its device uses one centrifugal effect, with which the mowed grass is thrown into the surrounding space at a distance of 1 meter. But for the narrow specialization of the lawn mower, this factor is not significant.

The advantage of the invention is that its device, in addition to centrifugal, uses a suction, fan effect, which allows you to suck in not only fragments of hard, cut and crushed material, but also gaseous and liquid. For example, the intake air, accelerating inside the spiral casing, accelerates the cut and crushed material and, under pressure, throws it through the exhaust pipe into the surrounding space with added speed. Or, for example, sucks water into the casing and, with the help of the added centrifugal force, drives it through the cavity of the hoses or fire hoses (attached to the exhaust pipe of the unit) in the desired direction.

The essence of the claimed device of the unit, including a casing, gasoline or other, existing at a technical level, engine, spiral casing with an inlet located in its lower region, an exhaust pipe located in the side region and a cutting tool located inside the casing, is that the cutting tool is made in the amount of several or one propeller, the blades of which are located in the plane of horizontal rotation.

The essence is that the cutting blades are the edges of the propeller blades, which are bent in a position whose configuration allows the blades to glide smoothly along the tangent surface of the material being cut.

The essence is that the cutting edges of the blades of the propeller blades are made in the form of a smooth blade of a table knife or in the form of a consecutive row of saw teeth on a tree or teeth (cutters) of a metal cutter.

The figures of the drawing depict variants of the unit, including the base 1 of the housing, the turntable 2, springs 3, wheels 4, the handle 5 for driving and control, hinges 6, height adjusters 7, engine 8, an energy source 9, for example, a gas tank, a working tool in the form propeller 10 with several blades 11, including cutting, chopping or sawing edges 12, the casing 13 with the inlet 14 and the exhaust pipe 15.

In FIG. 1 shows a side view of the unit in the transported position.

In FIG. 2 shows an aggregate, side view, in the process of milling the soil.

In FIG. 3 shows an aggregate, a side view, in a position ready for mowing lawns and other forbs.

In FIG. 4 shows an aggregate, a top view, the driving and control handle of which is swivelable to rotate 180 in a vertical plane and rotate the casing on a turntable in the horizontal plane 360 degrees.

In FIG. 5 shows the casing of the unit, bottom view.

In FIG. 6, top view, shows a fragment of a variant of the unit with one motor and two shrouds with propellers.

The portable unit for individual use by the device, service, size and appearance is almost no different from a household lawn mower with a gasoline or electric motor.

Unlike a modern lawn mower, the working knife in the unit has been replaced with a propeller 10. The cutting edges of the 12 blades 11 of the screw are made in the form of a knife blade, in the form of saw teeth on wood or in the form of carbide cutters similar to milling cutters for metal cutting.

The inclusion in the inventive device of an exclusive working tool allows you to turn it into a portable unit of wide use, capable of:

a) cut the grass of household plots (lawn mower);

b) form a fire band in wild grasses (mower);

c) cut off the top layer of soil (earth, sand, clay and other doughy substance) and throw it through the exhaust pipe 15 towards the approaching fire (replaces or complements the work of bayonet, shovels and knapsack water fire extinguishers);

d) to supply (with the help of fire hoses or hoses) water or other liquid, for example, of increased density, for example, from a nearby reservoir to the place of fire (replaces a centrifugal pump);

e) drain (using hoses) flooded basements and other rooms (pump);

f) to serve as an electric fan for inflatable amusement and rescue equipment, for example, such as “Cascade-5” (for firemen called “Life Cube”);

g) using a simple device, in an extreme situation, tow a paralyzed craft to the destination (water-jet propulsion).

The application considers a more autonomous unit with a gasoline engine 8, which is mounted on a turntable 2 of the base 1. The engine rotates the working tool in the form of a propeller 10 located under the springs 3 in the casing 13. The handle 5 on the hinges 6 rotates 180 in a vertical plane, therefore, the unit has no front and rear - the movement of the unit can begin in either of two directions (Figs. 1 and 4). Hinged to the turntable, the handle rotates in a horizontal plane 360 degrees with the circle and the casing, thereby allowing the direction of the exhaust port of the nozzle 15 to be set in any direction necessary for operation (Fig. 4). A simple unit arrangement allows, for example, using simple adjustments 7 to set the height of the cutting edges of the propeller blades to the desired height above the ground (Fig. 1 and 3). When cutting soil, the handle is rigidly fixed on the hinges and pressed down (Fig. 2). The handle tilts the left side of the casing with the cutting tool down, while bending the left consoles of the spring springs. In this position, the unit is ready for cutting the topsoil (Fig. 2). The unit moves one person. When the engine is turned on, the propeller 10 is rotated. The blades of the 11 screws, meeting solid material (grass, topsoil) with their edges 12 cut it off, grind it, disperse the casing 13 in a spiral and throw it into the environment through the exhaust pipe 15. Liquid is also thrown out into the environment or through hoses (fire hoses), dressed on the exhaust pipe, direct in the right direction. Working in the air fan mode, the blades of the unit through the hole 14 draw air into the casing and through the hoses, dressed on the exhaust pipe, pump up the elements of an inflatable attraction or fire-fighting “Life Cube” to the desired pressure.

In FIG. 5 depicts a fragment of a variant of a twin-screw unit. This arrangement of working tools complicates the device, but allows you to double the volume and width of the workpiece. Analogs with knives capture and throw out grass at a distance of one meter due to one centrifugal effect. The blades of the unit use an additional fan effect. The processed material is captured and sucked together with air, accelerated by a spiral of the casing, create a centrifugal effect with its end (end) areas, and with its help and with the help of a powerful air stream, the captured material (earth, sand) is thrown through the exhaust pipe to a distance of several meters . In order to lengthen the trajectory of the captured material, the trunk of the exhaust pipe is made slightly elevated above the ground at a given (optimal) angle.
