Electrically-driven movable crushing station

Abstract

The invention discloses an electrically-driven movable crushing station. The electrically-driven movable crushing station comprises a control device and a crushing execution mechanism, wherein the control device is electrically connected with an external power grid and the crushing execution mechanism; in the crushing process, the crushing execution mechanism is electrified by the external power grid and is controlled to work by virtue of the control device. The electrically-driven movable crushing station is electrified by the power grid, so that the working energy consumption and the operation cost of the movable crushing station are lowered, the noise pollution and the environmental pollution are reduced, the whole structure of the movable crushing station is simplified, and the production cost is lowered; a running system can be subjected to stepless speed regulation, is electrified by virtue of a storage battery and can be recycled, so that hostile work environments can be adapted, and faults are convenient to check and maintain.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an electrically driven mobile crushing station. Background technique [0002] Construction waste is waste generated during construction. The main recyclable components can be used to produce recycled aggregates. The crushing equipment can produce high-quality recycled aggregates after crushing, screening, and iron removal for construction waste. , thereby reducing environmental pollution and promoting resource reuse. Because the mobile crushing station only needs a small stacking site when it works, it is convenient to transfer to another site, and the transfer cost is lower. It is a key development equipment for the construction waste recycling industry. At present, the commonly used mobile crushing stations on the market use diesel engines as the driving source. The diesel engine is equipped with a hydraulic coupling to drive the crushing host, and the diesel eng...

AI Technical Summary

Problems solved by technology

[0003] The mobile crushing station that uses the traditional diesel engine to drive the hydraulic system has the following disadvantages: due to the use of the diesel engine as the power source, it will increase environmental pollution and noise pollution during work, and at the same time increase the production cost; The road is complex, and the high-power hydraulic pumps, hydraulic motors, hydraulic valves and other components used in the crusher are basically monopolized by a few foreign hydraulic parts manufacturers. Complex, harsh working environment, oil circuit pollution, oil circuit blockage, valve damage and other faults often occur in the hydraulic system. It is difficult to troubleshoot and solve faults at the work site, which increases the maintenance period and cost loss of production

[0004] There are also electric-driven crawler mobile crushing workstations on the market, which adopt the scheme of switching between diesel engine drive and electric drive. This drive system still mainly uses diesel engine as the power source, which will cause environmental pollution and noise pollution during work, and increase production. Cost; the power switching cabinet module is added in this scheme, which increases the complexity of the system and leads to an increase in cost; the walking system of the crushing station uses a motor to drive the hydraulic pump, which has low work efficiency, and the procurement cycle of some key components such as hydraulic pumps and hydraulic valves is long , not easy to buy, high cost, once a failure occurs, maintenance work is not easy
