Metering mechanism with vibration motor, applied for coal mine safety

Abstract

The invention discloses a metering mechanism with a vibration motor, applied for coal mine safety, and belongs to the technical field of coal mine metering devices. A large hydraulic cylinder base isfixedly disposed on the right side of a middle box body assembly; a large hydraulic cylinder is in movably hinged on the large hydraulic cylinder base via a first pin; a sector gate assembly is movably hinged between two sets of fixation bases by a second pin; a loading vibration part is fixedly assembled on the bottom end of the sector gate assembly via second bolts; a base body assembly is fixedly connected on the left side of the top of the loading vibration part via the second bolts; an upper cover plate assembly fitted with the sector gate assembly is movably hinged to the right side of the bottom of a fixation frame; and a measurement device is assembled under the loading vibration part. Overall automatic measurement has stable consistency; measurement accuracy is high; repeated andmultiple times of quantitative weighing of a coal mine can be satisfied; problems of coal mine weighing caused by manual factors can be effectively solved; manual labor strength is greatly reduced; and coal mine measurement efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of coal mine metering devices, in particular to a metering device with a vibrating motor for coal mine safety. Background technique [0002] At present, the domestic comprehensive mechanized mining equipment and technology are mainly designed for the geological conditions of northern coal seams, and are suitable for coal seam mining with thick coal seams, small inclination angles and small changes in coal seam thickness. During the coal mining process, it is necessary to measure the mined coal mines in batches For transportation, the existing measurement methods are calculated by manpower or judged according to experience, resulting in high labor intensity, and repeated manual weighing will cause potential inaccurate measurement, and it is impossible to guarantee the consistency of measurement for hundreds of times. At the same time, in the measurement process There are many unsafe factors in the coal mine, ...

Problems solved by technology

[0002] At present, the domestic comprehensive mechanized mining equipment and technology are mainly designed for the geological conditions of northern coal seams, and are suitable for coal seam mining with thick coal seams, small inclination angles and small changes in coal seam thickness. During the coal mining process, it is necessary to measure the mined coal mines in batches For transportation, the existing measurement methods are calculated by manpower or judged according to experience, resulting in high labor intensity, and repeated manual weighing will cause potential inaccurate measurement, and it is impossible to guarantee the consistency of measurement for hundreds of times. At the same time, in the measurement process There are many unsafe factors in the coal mine, and there are hidden dangers to human safety. Therefore, we propose a metering device with a vibrating motor for coal mine safety.
