Automatic overturning and coal-blending device

Abstract

The invention discloses an automatic overturning and coal-blending device. The automatic overturning and coal-blending device comprises a base support rack, a coal storage hopper, a weighing hopper and a transferring hopper, wherein four hydraulic support rods are arranged at the exterior of the weighing hopper and are connected to an overturning flat plate; a weighing device facing the bottom of the weighing hopper is arranged at the middle part of the overturning flat plate; a hydraulic cylinder bracket is arranged below a horizontal support plate; a hydraulic telescopic cylinder connected with the bottom of the overturning flat plate is arranged on the hydraulic cylinder bracket; a controller is arranged on the hydraulic cylinder bracket. By virtue of the manner, the weighing device of the automatic overturning and coal-blending device is used for sending signals to the controller when coal received in the weighing hopper reaches specified weight and controlling the hydraulic telescopic cylinder to contract so as to enable the weighing hopper to overturn; the weighted coal is instantly poured into the transferring hopper to be transported outwards. The automatic overturning and coal-blending device is high in working efficiency and automatic in operation; much labor and plenty of material resources are saved.

Description

technical field [0001] The invention relates to the design field of coal weighing and batching equipment, in particular to an automatic overturning coal blending device. Background technique [0002] The port industry is a key industry in my country's national economy. With the development of steel production, the popularization of urban coal gasification and the rise of coal mine coke ovens, the use of coal is still increasing. However, my country's coal preparation system is backward, equipment is outdated, and energy consumption The gap between the automation equipment and the international ones is very large, which seriously restricts the production level of coal blending. [0003] The existing coal blending device has backward technology, the discharge port of the hopper is at the bottom, the flow rate is small, the unloading speed of coal after weighing is slow, and the degree of automation is low, which affects the working efficiency of coal blending.
