SU1384513A1 - Skip loading device - Google Patents

Abstract

FIELD OF THE INVENTION The invention relates to coal and mining industry, in particular, to a skip loading device. The purpose of the invention is the improvement of operational reliability. The skip loading device contains a feeder 2, a hopper 3 disposed in chute 5 using an under-, weighing 6, and weighing mechanism 7. Suspension brackets 6 are placed at an angle J to the vertical, which is determined by the formula at arctg cos / G / 1 + 31pi, where is the angle of inclination of the hopper to the horizon, hail; Y - angle of attachment of suspensions to vertical, hail. The horn mass from the hopper 1 is fed to the hopper 3. When the predetermined dose is reached, the weighing mechanism 7 sends a signal to turn off the feeder 2 and unload it. In case of a breakdown of the weighing mechanism 7 or during its dismantling, an emergency situation will not arise, since, turning on the suspensions 6, the hopper 3 will leave the barrel. 1 il. i (L

Roystvu. Choosing the angle oi. and substituting in the form of the Purpose of the Invention - the increase we obtain the pleasure, in which reliability, in operation. So on weighing

The drawing schematically shows the mechanism 7; the total weight of the bunker boot device operates. ker-batcher 3 and, therefore. The device contains a bunker 1, under the weighing mechanism 7 it can be tared - in a special installation with which the feeder 2 is installed and the hopper 3 with the gate 4. The meter bunker is fixed in the channel 5 with the help of suspensions 6 and the weighing mechanism 7. Suspension installation goal 6 is chosen such that the full load (T (), is equal to the weight of the load (G). It determines the angle J from the equilibrium equation:

high accuracy.

The device works as follows.

In the presence of rock mass in the hopper 1 and the empty metering hopper 3, the feeder 2 is turned on, the material feeding it. Accumulating, the mountain mass acts on the weighing mechanism 7. When the specified dose is reached, the weighing mechanism 7 sends a signal to shut down the feeder 2. After the dispenser 3 is discharged into the skip, the cycle repeats. In case of breakdown 25 of the weighing mechanism 7 or during its dismantling, an emergency situation does not arise, since turning on the suspensions 6, the hopper 3 will leave the barrel.
