Grain scraper is one of the mechanical equipment frequently used by grain storage enterprises. In recent years, mechanical injury, electric shock and other production safety accidents are often caused due to illegal operation, improper maintenance and management. Among them, the main hazards are that there are dust and sundries in the power distribution box of grain scraper, the balance weight does not meet the requirements of equipment, the lack of protective cover, the damage of the distribution box and the junction box of the motor, and the insensitivity of the leakage protection or even without the leakage protection device. In order to improve the operators' awareness of the danger and operational risk of the scraper, and enhance the safety awareness of the operators, the measures are adopted, including to identify the hazard and determine the risk level, to develop operation and equipment movement plan respectively, to clean dust and debris in time, to balance equipment counterweight, to maintain or replace the trouble parts, and to set the warning labels and so on. Therefore to prevent and control the hazards caused by grain scraper, prolong the service life of equipment, ensure the safety of the workers prevent or reduce the similar production safety accidents.
