Abstract

The invention discloses a coal feeder type main shaft bucket standard weight device provided with a weighing device on the existing belt conveyor type coal feeder in mines, without occupying other space. The weighing device comprises: an instantaneous weighing device connected with a conveyer belt, a speed sensor connected with a driven roller and a calculator installed outside a machine; the calculator is connected with an inlet valve of a feed inlet by a signal wire. The instantaneous weighing device comprises: a weighing bridge, a weighing sensor, a weighing roller, and the like; the weighing bridge is in floating mode, which floats up and down along with the material weight change at the upper part of the conveyor belt; the weighing sensor connected with the weighing roller and the speed sensor connected with the driven roller input signals into the calculator for calculation so as to calculate the weight of transported material on the conveyor belt in a period of time. When the bucket standard weight load is reached, the calculator sends out signals to close a feed valve so as to realize continuous and uninterrupted bucket standard weight loading.

Description

technical field [0001] The invention relates to a mine equipment, in particular to a skip weighing device used on a main shaft hoist of a coal mine and installed on a coal feeder. Background technique [0002] According to Article 382 of the "Coal Mine Safety Regulations": "Skipping buckets must be loaded with fixed weight". At present, the skip lifting mechanism used in most mines in our country is as follows: a coal feeder is installed under the raw coal bunker, and the material is transported to the skip through the coal feeder. After reaching the predetermined tonnage, the coal feeder stops automatically. , so as to achieve the function of fixed weight loading. However, many old mines did not consider fixed-weight loading in the initial stage of well construction. In order to meet the requirements of the "Coal Mine Safety Regulations", the original system must be modified. Due to the limited space of many underground coal bunkers and the large volume of the fixed weigh...
