This mechanical broom contains: 1 - welded frame; 2 - internal combustion engine (ICE); 3 - centrifugal clutch; 4 - control handle; 5 - swivel bearing; 6 - removable bracket in the amount of 2 pieces; 7 - protective cover; 8 - adapter; 9 - disk brushes; 10 - gas handle (trigger); 11 - belt drive; 12 - rear wheels in the amount of 2 pieces; 13 - front support and adjusting wheel; 14 - front adjustment device; 15 - adjusting device of the control handle; 16 - vibration-proof rubber pad in the amount of 2 pieces; 17 - frame stop; 18 - gas cable; 19 - reducer of the actuator; 20 - control handle; 21 - spacer rings.

A mechanical broom works like this:

The operator pushes the broom in front of him, holding the control handles (20) of the broom, at an average walking speed (2-5 km/h).

Sweeping, sweeping, throwing, displacement of snow, sand, foliage and debris occurs forward in the direction of the broom, due to the rotational movement of the disk brushes (9) around its axis, installed using an adapter (8) at the ends of the output shafts of the actuator gearbox (19 ) brooms.

To ensure the operation of the working body (disk brush (9)) of the actuator, the broom uses an internal combustion engine (2), the torque is transmitted to it from the internal combustion engine (2) by means of a centrifugal clutch (3) installed on the output shaft of the internal combustion engine (2), then through belt drive (11) to the gearbox of the actuator (19).

The use of an internal combustion engine (2) ensures stable operation and smooth transmission of torque and an increase in the speed of rotation of the working body - disk brushes (9) of the actuator.

The handle (trigger) of the gas (10) allows you to select the optimal mode of operation of the internal combustion engine (2) and the working body - disk brushes (9) of the actuator as a whole.

The centrifugal clutch (3) of the clutch allows you to disable the work of the working body of the actuator and the actuator as a whole, when the internal combustion engine (2) is running at "idle speed" (from 600 to 800 rpm), this allows the operator, without turning off the internal combustion engine (2) , move the broom across the territory requiring cleaning, cleaning, without hindrance, if at the moment it is not required to carry out cleaning, cleaning.In the event of an unexpected load on the working body of the broom actuator, as a result of work, the use of belt drives allows you to remove an unexpected load on the internal combustion engine and the entire actuator, by slipping the belt between the belt pulleys.

The working body of the actuator is disc brushes (9), mounted through the adapter 8 on the output shafts of the gearbox (19) on both sides, rotate counterclockwise, allowing you to sweep snow, leaves, sand and debris from under the actuator forward, in the direction of travel devices. Adapter 8 is designed to connect the output shafts of the reducer with the working body of the actuator (disk brushes (9)), transfer torque from the reducer to the working body and collect the required number of disk brushes 9 at one end of the output shaft of the reducer (19), for the required cleaning width brooms. The disk brushes (9) are assembled through spacer rings 21, which ensure that the disk brushes (9) are fixed in the adapter (8) in a predetermined position. The cleaning width of the device, in one pass, can be from 600 to 900 mm, depending on the length of the output shafts of the gearbox (19) of the actuator and the power of the internal combustion engine (2) of the broom used in each individual and specific case of the broom.

The original design of the protective cover (7) installed on the frame (1) of the broom over the actuator has a visor that protects the operator, the main components and mechanisms of the device from snow powder, dust and dirt resulting from the rotation of the working body of the actuator.

The ends of the gearbox shafts (19) are additionally installed in the rolling bearings of the removable brackets (6) that are attached to the frame of the device (1) from both sides. Removable brackets (6) are made in the form of a channel to provide the necessary rigidity for deflection in the vertical and horizontal directions, and are designed to fix the ends of the output shaft of the gearbox (19) in the housing with a rolling bearing and articulation with the frame of the device (1) by means of fixing bolts.

Removable brackets (6) provide the necessary rigidity and integrity of the entire structure, reduce the beating and vibration that occurs at the ends of the shafts during the operation of the broom. Removable brackets (6) can be detached from the frame (1), which in turn provides free access to the adapter (8) in case of replacing the disk brushes (9) and replacing the rolling bearing in case of failure.

The swivel bearing assembly (5) serves to articulate the broom frame (1) with the internal combustion engine installed and fixed on it (2), the protective cover (7), the actuator, the removable bracket (6) and the control handle (4) with the internal combustion engine controls (handle (trigger) of gas (10)), adjusting mechanism of the control handle (15), frame stop (17) and rear wheels (12).

The turntable (5) consists of a support plate rigidly fixed on the lower part of the control handle (4) in front of the rear wheels (12) of the broom. On top of the support plate, an adjusting plate is installed with the frame of the device rigidly fixed on it (1). The adjusting plate has an adjusting groove made along the radius of rotation of the turntable (5) and is fixed with an adjusting nut. The plates are fixed to each other with a clamping nut.

The turntable (5) is also designed to regulate the position of the actuator mounted on the frame (1) of the broom relative to the direction of movement of the device to the left or right, to a certain angle of rotation (angle of rotation - from 0 to 25 degrees) if necessary during operation brooms.

To adjust, turn the actuator to the left or right, to the required angle of rotation (from 0 to 25 degrees), it is necessary to loosen the clamping and adjusting nuts, turn the frame (1) of the device to the left or right to the required angle of rotation (from 0 to 25 degrees) and tighten the nuts, thereby fixing the actuator

The swivel bearing (5) allows turning the actuator and ensures that the disk brush (9) is thrown away, when cleaning the surface, snow, foliage, earth, etc. as in front of you, or to the left or right side of you.

The front support and adjustment wheel (13) in conjunction with the front adjustment device (14) made it possible to distribute the total mass between the front support and adjustment wheel (13) and the rear wheels (12), reduce the load on the working body of the actuator, and made it possible to adjust the height of the actuator , during the operation of the actuator, its working body - the disk brush (9) wears out (wears), which leads to a decrease in the diameter of the disk brushes (9); regulate the required force (pressure) of the working body of the actuator on the cleaning surface during operation, when moving "forward" automatically raise the actuator, which in turn facilitates the operation of the internal combustion engine (2) - reduces the load due to the design of the device; increase the stability and maneuverability of the device during operation, as well as when moving forward and in the opposite direction.

The installed frame stop (17) on the control handle (4) behind the axis of rotation of the rear wheels (12) ensures the lifting of the actuator when pressing the frame stop (17) with the operator's foot, in case of an obstacle in front of the front rotary adjustment wheel (13).

Vibration-proof rubber pads (16) installed on the handles of the control handle (20) dampen the vibrations of the broom during the operation of the internal combustion engine (2), ensuring comfortable work for the operator.

Thus, the use of the described mechanical broom can significantly increase the efficiency, quality and speed of cleaning the territory in winter from snow and snow deposits up to 25 cm high, and the rest of the time (spring, summer and autumn) - from dirt, fallen leaves and debris , reduces the physical and muscular efforts of the operator in the process of cleaning the territory.

This device can be considered universal and designed for year-round use.
