Description

The utility model relates to the field of municipal equipment intended for cleaning hard-surfaced surfaces from debris and dust, and can be used for cleaning city pedestrian paths, sidewalks and local areas around buildings and structures.

Sweeping-vacuum communal machines are known from the prior art, operating in part by concentrating cylindrical and/or tray brushes on the removed surface of the garbage in the form of a roll of sweeping material and subsequently moving this sweeping material into a hopper through a pipeline by creating low air pressure in the receiving hopper.

Thus, a vacuum cleaning machine is known from the state of the art [1], which includes a self-propelled chassis with a driver’s cab, a humidification system, a cylindrical sweeper, a cyclone hopper, shafts for forced movement of waste into the cyclone hopper and two tray brushes. In this case, the cyclone bunker is made in the form of an evacuated container, communicating with the shafts for moving the estimate, and contains a bladed draft stimulator installed inside it, which is made on the basis of a suction fan with a hydraulic drive, the shaft for moving the estimate into the cyclone bunker is made in the form of a branch pipe, one of the ends of which is inserted into the cyclone hopper, and the second end of which is intended for sucking up waste, and the first and second tray brushes are mounted on holding rods and equipped with forced rotation drives, with the ability to change the angle between the transverse axis of the self-propelled automobile chassis and the longitudinal axis of the holding rods in the direction of movement of the self-propelled automobile chassis in an interval of more than zero, but less than fifty degrees.

The disadvantage of the known vacuum cleaning machine is that it pollutes the environment during its operation with exhaust products from an internal combustion engine. This environmental pollution is especially relevant from an environmental point of view in the case of using the mentioned sweeper-vacuum machine in an urban environment.

The closest in technical essence and achieved result is the well-known vacuum sweeper machine [2]. It consists of a four-wheeled self-propelled transport chassis with a frame formed by two mating half-frames, a bunker for receiving waste with a traction stimulator under the bunker cover based on a turbine with a hydraulic motor. The volume of the bunker is connected through a shaft equipped with a suction pipe to the waste collection area. There is a diesel engine with a diesel fuel tank, fuel line and exhaust pipe. The vacuum cleaning machine under consideration is equipped with a nozzle for forced irrigation of the surface to be cleaned with sprayed water in the cleaning area, which communicates through a hydraulic pump with the water tank. The machine is equipped with two tray brushes and a hydraulic station that interacts through pipelines with hydraulic cylinders for manipulation (in terms of raising and lowering the hopper and/or hopper lid). This known device is taken as a prototype device.

The disadvantage of the vacuum cleaning machine chosen as a prototype is the significant consumption of diesel fuel.

The problem to which the proposed technical solution is aimed is to reduce the burden on the environment due to the long hours of operation of a diesel engine associated with its exhaust.

The technical result expected from the use of the proposed vacuum cleaning machine with a diesel drive is to reduce diesel fuel consumption.

The stated technical result is achieved by the fact that the proposed vacuum cleaning machine with a diesel drive is formed by a self-propelled transport chassis in the form of interconnected front and rear semi-frames, a driver's cabin with a control unit consisting of a color monitor, a joystick and a microprocessor of CortexA9+4MS architecture installed on it a program for providing an on-board electronic control system for a sweeper-vacuum machine, a water accumulator with a means of its forced supply to the area for collecting estimates through spray nozzles, a hydraulic station, a bunker for receiving estimates containing a hatch, connected to the hopper by a suction shaft and a flexible hose for manually moving estimates by means of creating a vacuum with a traction stimulator fixed under the hatch, right and left tray brushes and an internal combustion engine with a tank for diesel fuel, a fuel line and an exhaust pipe, while the means of forced water supply is made in the form of a hydraulic pump, and a hydraulically driven turbine is used as a traction stimulator, Moreover, the coupling of the front and rear semi-frames is ensured by the axis of articulation with the fixation bracket.

- It is advisable that in a diesel-driven vacuum sweeper, the hatch of the bunker for receiving waste waste should be equipped with a lifting and lowering hydraulic cylinder.

- It is important that the bunker for receiving waste is equipped with a hydraulic cylinder for changing its spatial position above the chassis.

- It is preferable that the hydraulic actuators are communicated with the hydraulic station via pipelines.

EXAMPLE No. 1

Since the process of vacuum cleaning both in the prototype device and in the case of using the proposed vacuum cleaning machine with a diesel drive occurs with changes in the speed and trajectory of their movement (due to the geometry of the pedestrian paths and sidewalks being cleaned), comparative tests of both devices were carried out on the reserve take-off - landing strip (RW) of Sheremetyevo-2 airport under the following conditions:

- Using a laser rangefinder, we noted a distance of 1200 meters.

- the prototype device and the claimed device 1 (Fig. 1.1) were filled with diesel fuel in a volume of 20 liters from a measuring container through the corresponding necks of the fuel tanks, in particular for the claimed device 17 (Fig. 1.1).

Having started the diesel engine of the prototype device, we drove the previously measured distance there and back five times. The speed was set to 12 km/h. The same was done with the declared device 1 (Fig. 1.1). Both devices were equipped with VMMotoriEuromot3FR754 diesel engines (diesel fuel consumption 5 l/h). Having drained the remaining fuel into a measuring container after the races, it was found that the difference between the volumes of consumed diesel fuel in both devices is less than 0.3%.

Next, artificial bumps were installed along the distance (GOST 52605-20006). At the start and end lines of the distance, prefabricated artificial bumps (IH) were installed every 100 meters of the distance. Again, the prototype device and the proposed device were each filled with 20 liters of diesel fuel. Before starting the distance in the prototype device, the engine and water supply were started through the water irrigation nozzle 21, the turbine drive hydraulic motor and both tray brushes. We started moving to the first IP at a speed of 12 km/h. Next, the driver adapted the speed taking into account the passage of the IP, and again restored the speed to 12 km/h. Upon completion of five runs of the distance, the remaining diesel fuel was poured into a measuring container.

Before starting the distance in the claimed device 1.1 (Fig. 1), the engine and water supply were started through the water spray nozzle 21, the turbine drive hydraulic motor and both tray brushes 5.1 and 5.2 (Fig. 1.2). The driver started driving to the first IP at a speed of 12 km/h. Next, he adapted the speed of movement to the speed of passing the IP, overcoming each of which the speed of movement was again restored up to 12 km/h. Upon completion of five passes of the distance, as in example No. 1, the remaining diesel fuel was poured into a measuring container. Their number was recorded and entered into the table. Comparative results are given in Tab. 1

As follows from Table No. 1, the use of the claimed vacuum cleaning machine with a diesel drive made it possible to reduce fuel consumption by 0.4 liters. (i.e. by 6.7%) compared to the prototype device. The latter circumstance confirms the achievement of the stated technical result in the form of reduced diesel fuel consumption. It was impossible to expect a different result, since, unlike the prototype device, the movement of which during operation is associated with the operation at full power (and maximum consumption of diesel fuel) of all components and mechanisms, including the hydraulic station, tray brushes and turbine at that time as in the proposed device, thanks to the software installed in the control unit 30 (Fig. 3), the operating mode of the above-mentioned components and mechanisms is adapted (coordinated) to the speed of movement during the cleaning process of the proposed vacuum cleaning machine with a diesel drive.
