Abstract

The invention discloses improved skip weight-fixed loading equipment, which belongs to the technical field of weighing. A sector gate is mounted at an discharge port of a weight-fixing hopper; a weighing sensor is mounted at the bottom of the weight-fixing hopper; an sector gate oil cylinder is welded on the side wall of the weight-fixing hopper; the sector gate is connected with the sector gate oil cylinder; a coal level meter is mounted in a surge bunker; the discharge port of the surge bunker is positioned at the bottom of the bunker; a flat gate is mounted at the discharge port and is connected with a flat gate oil cylinder; the surge bunker is positioned right above the weight-fixing hopper; counterweight lifting oil cylinders are mounted below the two side walls of the weight-fixing hopper respectively; the oil paths of the flat gate oil cylinder, the counterweight lifting oil cylinders and the sector gate oil cylinder are connected with a hydraulic pump station; the coal lever meter, the weighing sensor, a belt conveyor and the hydraulic pump station are electrically connected with a controller in a lifting control chamber. The improved skip weight-fixed loading equipment has the advantages of high coal loading precision, strong reliability, avoidance of frequent exchange of the weighing sensor and reduction in maintenance cost.

Description

technical field

[0001] The invention relates to an improved skip fixed-weight loading device, which belongs to the technical field of weighing. Background technique

[0002] Skip loading equipment is an intermediate storage and metering device for loading raw coal from underground coal bunkers to skips. In the early days of the founding of the People's Republic of my country, the pressure plate type sliding coal nozzle was widely used as the loading equipment in our country. This kind of loading equipment has a large amount of coal spreading and a large impact force when loading coal, so quantitative loading cannot be realized, which seriously affects the safety of coal mine production. Most of the vertical shaft skip loading equipment used in coal mines built in the 1980s is of the quantitative bucket type. This is a pre-measured loading method, which can not only greatly reduce the amount of coal scattered, but also facilitate automatic lifting. However, this loading met...

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Such as figure 1 with figure 2 As shown, the present invention comprises quantitative bucket 6, weighing sensor 9, fan-shaped gate oil cylinder 11 and fan-shaped gate 12, and fan-shaped gate 12 is installed at the discharge port of quantitative bucket 6, and weighing sensor 9 is installed at the bottom of quantitative bucket 6, and fan-shaped The gate oil cylinder 11 is welded on the side wall of the quantitative bucket 6, and the sector gate 12 is connected with the sector gate oil cylinder 11. It also includes a buffer bin 2 and a standard weight 10. A coal level gauge 3 is installed inside the buffer bin 2. The buffer bin 2 is installed under the chute of the belt conveyor 1. The buffer bin 2 is an inverted cone structure. The discharge of the buffer bin 2 The opening is located at the bottom of the bin, and a flat gate 5 is installed at the discharge port. The...
