Snow sweeper and power supply control method thereof

Abstract

The invention provides a snow sweeper, which comprises a self-walking system, a snow sweeping system, a self-walking battery pack and a snow sweeping battery pack, wherein the self-walking battery pack and the snow sweeping battery pack respectively provide electric energy for the self-walking system and the snow sweeping system. The self-walking system comprises a self-walking device, a self-walking motor and a self-walking controller, and the self-walking battery pack is connected with the self-walking motor through the self-walking controller. The snow sweeping system comprises a snow sweeping device, a snow sweeping motor and a snow sweeping controller, and the snow sweeping battery pack is connected with the snow sweeping motor through the snow sweeping controller. The self-walking controller and the snow sweeping controller are mutually independent. According to the arrangement, the self-walking function and the snow sweeping function of the snow sweeper can be mutually independent, and the condition that the controller for controlling the self-walking and the snow sweeping work in the traditional snow sweeper is mutually interfered is avoided. The power supply control methodof the snow sweeper is simple, an operator can control the snow sweeper to switch between a self-walking mode and a snow sweeper mode according to the actual working condition of the snow sweeper, and the self-walking mode and the snow sweeper work are simultaneously carried out, so that the operability of the snow sweeper is improved.

Description

technical field [0001] The invention relates to the technical field of snow removal equipment, in particular to a snow removal machine and a power supply control method thereof. Background technique [0002] Due to the large power demand of the snowplow, a single battery device cannot meet the power supply requirements. Therefore, two battery devices are generally used to supply power in parallel or in series to prolong the working time of the electric tool and improve the efficiency of the electric tool. [0003] Existing snowplows generally adopt a lithium battery pack for power supply. However, the snowplow powered by lithium batteries has the following problems: when two battery packs are used in series or in parallel for power supply, when one of the battery packs or the control circuit works unstable or fails, it will affect the other battery pack or control circuit. The normal operation of the circuit may even cause damage to the battery pack or the control board, ca...

AI Technical Summary

Problems solved by technology

However, the snowplow powered by lithium batteries has the following problems: when two battery packs are used in series or in parallel for power supply, when one of the battery packs or the control circuit works unstable or fails, it will affect the other battery pack or control circuit. The normal operation of the circuit may even cause damage to the battery pack or the control board, causing the snowplow to not work normally

Moreover, the circuit design of the system controlling the two sets of battery packs is complex and is prone to interference between lines, which is not conducive to the modularization of the whole machine, and the maintenance process of the snowplow is complicated and the maintenance cost is high
