Electric sweeper

Abstract

The invention relates to an electric sweeper. Power of the electric sweeper adopts eight 6V190Ah lead acid batteries and a DC (Direct Current) brushless motor in which a rear axle is arranged; the electric sweeper consists of a motor controller, a DC-DC (Direct Current to Direct Current) control module, a liquid level sensor conditioning circuit, a rotating speed sensor and other control circuits on circuit and structurally comprises a vehicle body, a frame, a sweeping mechanism, a lifting mechanism, a refuse hopper and a spraying mechanism; the sweeping mechanism adopts two side brushes rotating reversely, a lifting motor connected with the two side brushes, a middle brush and a protective frame; the lifting mechanism comprises a refuse lifting belt, a hoisting motor, a chain, a belt supporting seat and a housing for packaging the refuse lifting belt; both sides of the refuse hopper are provided with lifting motors; and the spraying mechanism consists of a water tank, a water pump and a conduit connected with the water pump. The electric sweeper has the key points that the two side brushes and the middle brush are respectively provided with one hub motor; the hub motors on the two side brushes have opposite rotating directions, so that refuse is guaranteed to move towards the middle and then is sent into a feed inlet of the lifting belt housing by the middle brush; the lifting motor drives the refuse lifting belt by the chain to send the refuse into the refuse hopper; the two side brushes are connected with the lifting motors to ensure that the side brushes are separated from the ground when the sweeper runs; combination of the refuse hopper and the lifting motors implements the automatic dumping of the refuse.

Description

technical field [0001] The invention relates to an electric cleaning vehicle, which controls a motor through a control circuit to drive a brush handle to complete ground cleaning work. Background technique [0002] The traditional cleaning work is manual, the labor intensity of the workers is high, the working environment is poor, and it is not safe. The cost of large-scale engineering vehicles is high, mainly powered by internal combustion engines, the work is noisy, and it also emits exhaust gas, causing secondary pollution. The general trend of energy saving and environmental protection. The invention provides an all-electric cleaning vehicle, which uses a battery as power, and controls a DC brushless motor and a hub motor to complete cleaning work through a controller. The cleaning vehicle has low noise, zero emissions, energy saving and environmental protection, simple operation, and high working efficiency. It is 20 times that of manual cleaning, especially suitable f...
