detailed description

Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. detailed instructions.

As shown in Figures 1 and 2, the fully enclosed driving type pure electric four-wheel front-drive road sweeper includes a vehicle chassis 6, wheels 5 and a front drive assembly 2, the wheels 5 are installed on the vehicle chassis 6, and the front drive assembly 2 It is arranged at the front of the vehicle chassis 6, and a battery pack 8 is arranged on the top of the vehicle chassis 6, and the battery pack 8 supplies power for the front drive assembly 2 and other systems of the vehicle, and also includes the front side brush assembly 1, the rolling brush mechanism 4 and the dust collection assembly 7. The front brush assembly 1 is arranged at the bottom of the front end of the vehicle chassis 6, and the rolling brush mechanism 4 is arranged at the bottom of the vehicle chassis 6 to cooperate with the dust collection assembly 7, which is installed at the rear of the vehicle chassis 6.

As shown in Figure 1, the front drive assembly 1 includes an independent suspension mechanism, a differential gear box, a drive motor and a half shaft of the ball cage. When the machine is running, the drive motor drives the differential gear box, and the differential gear box drives the half shaft of the ball cage. Rotate, thereby providing machine forward power.

The rear side brush assembly 3 is installed on the bottom of the vehicle chassis 6, and the rear side brush assembly 3 is arranged between the front side brush assembly 1 and the rolling brush mechanism 4. Front side brush assembly 1 includes side brush one 11 and side brush two 12, side brush one 11 and side brush two 12 are arranged on the left and right sides of vehicle chassis 6 respectively, the structure and diameter of side brush one 11 and side brush two 12 Are the same. The rear side brush assembly 3 includes a side brush 3 31 and a side brush 4 32, the side brush 3 31 and the side brush 4 32 are arranged on the left and right sides of the vehicle chassis 6 respectively, the structures and diameters of the side brush 3 31 and the side brush 4 32 Are the same. The diameter of the above-mentioned side brush one 11 is greater than that of the side brush three 31, which can better collect dust. The aforementioned rolling brush mechanism is composed of two brushes placed side by side to sweep the dust to the dust collection assembly within 7.

As shown in Figure 4, when the road sweeper is started, the rolling brush thrust rod 42 is energized to work at the same time, and the rolling brush thrust rod 42 is elongated, so that the drawing wire connecting the rolling brush thrust rod 42 and the hair brush 41 is elongated, and the rolling brush mechanism 4. Lower to the working position by its own weight and pressurizing device, and start working. The roller brush mechanism 4 gathers the rubbish and dust swept by the side brush three 31 and the side brush four 32 by the hairbrush 41 of the roller brush mechanism 4, and rotates clockwise by the roller brush to throw the gathered rubbish and dust to the dust collector. into the 7 position.

As shown in Figure 3, dust collecting assembly 7 is made up of centrifugal fan 71, filter cylinder 72, dustbin 73 and shocking device 74; The centrifugal fan 71 rotates to extract the air in the dustbin 73 to form a negative pressure in the dustbin 73. At this time, the air pressure in the dustbin 73 is lower than the air pressure in the main brush box, and the dust will enter the dustbin 73 with the air pressure. 72 can filter dust, make centrifugal blower 71 only discharge air, and dust stays in dustbin 73 and filter cartridge 72, and the dust attached to the dust in filter cartridge 72 enters in dustbin 73 by shaking device 74 work, avoids dust pollution.

The use method of the pure electric four-wheel front-drive road sweeper includes the following steps: A. Start the road sweeper, and the side brush one 11 and the side brush two 12 rotate to work, collecting dust between the brushes on both sides; B. The dust collected by side brush one 11 and side brush two 12 during the movement of the vehicle is swept to the roller brush mechanism 4 by the smaller diameter side brush three 31 and side brush four 32; Sweep into the dust collection assembly 7 with the rubbish collected by the brush assembly 3 on the rear side.

The road sweeper is driven by electric energy, and all energy consumption is provided by the battery pack 8, which greatly saves energy. The front end of the vehicle chassis 6 is provided with a front drive assembly 2, and the road sweeper is powered by the front drive assembly 2, and the wheels 5 It is a driven wheel, and the cab is fully enclosed to prevent dust from entering and affecting the health of the driver.

The front end of the sweeper is equipped with a front brush assembly 1, the middle is equipped with a rear brush assembly 3, a rolling brush mechanism 4, and the rear end is equipped with a dust collection assembly 7. The rubbish is cleaned out, and the rubbish is gathered in the middle of the sweeper by the back brush assembly 3, because the diameter of the side brush one 11 is greater than the diameter of the side brush three 31, so the gathering effect of the side brush assembly is good, and finally the rolling brush mechanism 4 will Garbage is swept into the dust collection assembly 7; all motor power is provided by the battery pack 8 and controlled by the electronic control device 9, which greatly improves work efficiency, has no tail gas emission, low energy consumption, energy saving and environmental protection. The above electric control device 9 is composed of a main DC contactor, a drive controller, various functional relays, a main brush controller, and various functional switches. The vehicle sends various functional signals to the functional relays through the button switches. Different motors supply power to enable various functions of the vehicle to work properly.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements are adopted in the method concept and technical solutions of the present invention, or there is no improvement Directly applying the conception and technical solutions of the present invention to other occasions falls within the protection scope of the present invention.
