Description

The utility model relates to the field of municipal engineering, namely to sweeping and harvesting equipment, and can be used for cleaning yards, streets, sidewalks and other closed areas.

Known manual combined machine for cleaning the territory (patent RU 2205915 C1 dated 10.06.2003, 2002110670/28, 04.22.2002), containing a manually operated trolley, made in the form of a frame with a handle and equipped with a removable container, a working body in the form of a sweeping brush. The trolley has a detachable connection that allows you to disconnect the working body and use the rest as a trolley with a removable container, which has stiffeners on two opposite sides with holes for installing removable handles in them, in addition, the machine is equipped with an additional replaceable working body in the form of a scraper for snow removal, and the sweeping brush is equipped with a removable hopper into which debris is swept when sweeping the area.

The disadvantages of this machine are: the inability to take small and medium-sized debris into the container, the use of a half-open casing raises dust towards the operator, large overall dimensions and weight make the device less mobile and reduce work efficiency.

A lever device for sweeping streets and roads is known (patent RU 2576172 C1 dated February 27, 2016 Bull. No. 6 2014150138/13, December 10, 2014), containing a brush with a scraper, a handle with a support-movable mechanism. At the bottom, a removable wheel with a spring shock absorber is fixed on the handle, the handle itself has a round cross section and freely rotates inside the pipes for the removable wheel and the thrust pipe. The process of sweeping streets and roads is carried out as a result of the frontal movement of the device by the operator.

The disadvantages are: the application of significant mechanical force on the handle to press the brush to the surface to be swept. If the surface is uneven, there is no clamping, as a result of which there is an incomplete collection of garbage, as well as the absence of any container for the collected garbage.

The closest technical solution is a garbage disposal device (patent RU 2209266 C2 dated 07/27/2003, 2001105689/28, 02/27/2001), containing a protective cover and a cylindrical brush with a mechanism for driving a cylindrical brush from the support wheels, the protective cover includes a lower part connected together with guide plates, forms pockets for collecting debris and is closed with a lid on top.

The disadvantage of this design is the high complexity of cleaning pockets of debris, the need for constant monitoring of the horizontal position of the device relative to the swept surface, the need to maintain a high walking speed by the operator to effectively clean the area or to achieve high angular velocities of the brush mechanism.

The technical result consists in creating an efficient mechanical device for cleaning territories.

The technical result is achieved by the fact that a mechanical device for cleaning the territory, consisting of a body, to the front of which support wheels and a cylindrical brush are rigidly attached, according to the utility model, levers are installed on both sides of the body, with the possibility of their vertical and horizontal movement relative to the body, one the lever includes a chain drive, consisting of a large sprocket rigidly connected to the wheel and a small sprocket rigidly connected to the output shaft of the cylindrical brush, the second lever consists of a belt drive, including a large pulley rigidly connected to the wheel, and the small pulley has two grooves for the belt, one of which transmits rotation to the curb brush in a semi-cross pattern, which is rigidly fixed on a bracket that is attached to the body, a height-adjustable handle is installed in the upper part of the body, a bag is installed in the back of the body, attached to the body with fixing elements , the bag is supported by a strap rigidly attached to the handle of the device.

The utility model is illustrated by drawings.

In FIG. 1 shows a diagram of the elements of a mechanical device for cleaning the territory.

In FIG. 2 shows a diagram of a chain drive of a mechanical device for cleaning the territory.

In FIG. 3 shows a diagram of a belt drive of a mechanical device for cleaning the territory.

A mechanical device for cleaning small and medium-sized debris includes a body 1, to which two levers 2,3 are attached, having height adjustment and including a chain drive 4, consisting of a large sprocket 5 and a small sprocket 6, a belt drive 7, consisting from a large pulley 8, as well as a small pulley 9, two support wheels 10, a curb brush 11 with a shaft 12, which is rigidly attached to the bracket 13, a cylindrical brush 14 installed inside the housing, a device handle 15 installed in the upper part of the housing and having height adjustment, a bag 16 installed in the back of the case and fixed with the help of fixing elements 17 to the case, and with a strap 18 rigidly fixed on the handle of the device.

The device works as follows. When driving, two support wheels (10) rotate on levers (2, 3) rigidly connected to the large pulley (8) and large sprocket (5), transferring rotation through the belt and chain to the small pulley (9) and small sprocket (6) , thus increasing the output speed of the cylindrical brush (14), the small pulley (9) has two belt grooves, one of which transmits rotation to the curb brush (11) in a semi-cross pattern. Thus, oncoming debris is swept out from the corners, edges of the curb and enters the cavities of the cylindrical brush (14), which rotates in the direction of the bag (16) fixed with the help of locking elements (17) in the back of the body. The levers (2, 3) of the device are height-adjustable, thereby lowering or raising the cylindrical brush (14).
