Description

Fully enclosed rear rolling sweeping energy-saving and environmental protection road sweeper

technical field

The invention relates to the technical field of sanitation equipment, in particular to an energy-saving and environment-friendly road sweeper with fully enclosed rear rolling sweep.

Background technique

At present, most of the road sweepers produced in China are suction-sweeping structures, and the main forms are front or middle side sweeping brushes, and middle or rear suction nozzles. The suction sweeping road sweeper is equipped with two engines, namely the main engine and the auxiliary engine. The main engine is used to drive the road sweeper, and the auxiliary engine provides power for the middle or rear suction nozzle. For example, a medium-sized road sweeper with a garbage bin volume of 3.5m ³ is generally equipped with a 70KW main engine and a 57KW auxiliary engine, resulting in a large energy consumption for a road sweeper with this structure.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art and provide a fully enclosed rear sweeping energy-saving and environment-friendly road sweeper. Its innovative point is that one engine provides power for the whole vehicle, which mainly solves the energy consumption of existing road sweepers. Big and other issues.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A fully enclosed rear-sweeping energy-saving and environment-friendly road sweeper, including a car chassis, a central side sweeping brush, a water circulation system, a hydraulic system, an upper garbage bin, and a rear garbage collection device. The engine provides power for the whole vehicle; in addition to driving the vehicle, the engine can also drive the high-pressure water pump in the water circulation system, the hydraulic pump in the hydraulic system and the rear garbage collection device to work; specifically:

The high-pressure water pump in the water circulation system provides high-pressure water to the sprinkler pipe installed on the front end of the automobile chassis and the sprinkler plate installed on the side sweeper;

The hydraulic pump in the hydraulic system provides high-pressure oil to the hydraulic motor and oil cylinder I installed on the side sweep brush and the oil cylinder II and oil cylinder III installed on the chassis of the car;

The rear garbage collection device is hinged with the bearing seat installed on the chassis of the car; the power required by the garbage collection device comes from the rear axle of the car, and the power collected by the rear axle of the car is first transmitted to the electromagnetic clutch and the universal The universal joint shaft transmits the power to the gearbox, and the gearbox separates two output shafts, which respectively transmit the power to the universal joint shaft II and the universal joint shaft III; the universal joint shaft II drives the sprocket I Rotate, and transmit the power to the sprocket II through the chain; the gear I coaxial with the sprocket II meshes with the gear II, and the gear II drives the rolling brush in the main cleaning device to rotate, and the high-speed rotating rolling brush will The garbage on the ground is swept into the auger through the garbage outlet I; at the same time, the cardan shaft II drives the lower shaft of the garbage lifting device to rotate together with the conveyor belt; the cardan shaft III transmits the power to the sprocket IV, and then The sprocket IV transmits the power to the sprocket III through the chain, and the sprocket III drives the screw shaft in the auger to rotate; the screw shaft rotates in the same direction as the conveyor belt in the garbage lifting device, and sweeps the rolling brush into the auger. The garbage in Longzhong is successively sent into the garbage hopper installed on the conveyor belt through the garbage outlet II, and the garbage hopper is driven upward by the conveyor belt, and the garbage is sent into the garbage bin one after another.

As an improvement of the present invention, the side sweeping brushes installed on both sides of the chassis of the automobile are driven to rotate by a hydraulic motor, and the position of the brushes can be adjusted through the expansion and contraction of the oil cylinder I.

As an improvement of the present invention, the position of the main cleaning device can be adjusted through the expansion and contraction of the oil cylinder II installed on the chassis of the automobile.

As an improvement of the present invention, a rectangular hole is opened at the bottom of the housing of the main cleaning device, and a front sealing plate, a left and right sealing plate and a rear sealing plate are respectively installed around the rectangular hole, so that the housing A sealed cavity is formed with the ground; casters are installed at the rear of the housing.

As an improvement of the present invention, the rolling brush in the main cleaning device is installed eccentrically with the housing, that is, the central axis O ₁ of the rolling brush deviates from the central axis O ₂ of the housing, and O ₁ is relatively O ₂ moves 20-30mm to the left and 30-50mm downward, so that the brush has a certain amount of compression when in contact with the ground, and maintains a certain amount of compression with the lower part of the garbage outlet of the housing.

其中，m为毛刷数量，D为毛刷圆周直径。As an improvement of the present invention, the relationship between the horizontal moving velocity v of the main cleaning mechanism and the rotational angular velocity _ω of the rolling brush with the chassis of the automobile is:

Among them, m is the number of brushes, and D is the diameter of the brush circle.

时，滚扫刷与地面做纯滚动，没有拖动现象；若滚扫刷在地面上被拖着平移，直接影响了清扫洁净率。when

When the rolling brush and the ground do pure rolling, there is no dragging phenomenon; if The rolling brush is dragged and translated on the ground, which directly affects the cleaning rate.

The relationship between the rotational angular velocity ω ₁ of the rolling sweep brush and the rotational angular velocity ω ₂ of the screw shaft is: ω ₂ : ω ₁ =mn, wherein, m is the number of hair brushes, and n is the number of spiral turns; Once the garbage exit I, the screw shaft rotates a circle, so that the garbage can be collected to the garbage outlet II in time, and the garbage will not be blocked in the auger.

其中，l为两垃圾斗之间的距离，d为下转轴的直径。螺旋轴每转动一圈，垃圾向垃圾出口Ⅱ聚集一次，垃圾斗转过一个，使垃圾能及时提升上去。The relationship between the angular velocity _ω2 of the spiral shaft rotation and the rotational angular velocity _ω3 of the conveyor belt is:

Wherein, l is the distance between the two garbage bins, and d is the diameter of the lower rotating shaft. Every time the screw shaft rotates one circle, the garbage gathers to the garbage outlet II once, and the garbage bucket rotates once, so that the garbage can be lifted up in time.

As an improvement of the present invention, the garbage bin is tilted backward around the bearing seat through the oil cylinder III installed on the chassis of the automobile, and drives the upper shell of the garbage lifting device, the spring pull rod and the rear cover of the garbage bin to rotate. The rear lid of the dustbin gradually opens.

In the present invention, the rolling sweeping brush and the casing are installed eccentrically, so the frictional resistance produced is small, and the power consumption is also small during operation. The power can be collected from the surplus power of the main engine, so that the original auxiliary engine can be canceled and the energy consumption. After testing, as adopting an engine to provide power for the whole car, because the required power of the garbage collection mechanism of the present invention is less than 5 horsepower, it can be collected from the engine of the car completely. Road sweeping vehicles can save more than 50% of energy consumption.
