And a positioning device for positioning the position of the sector gate is arranged on the outer side of the same side of the material guide groove. The sector gate can conveniently adjust the feeding amount, and has the advantages of simple driving, light weight and small investment.

Description

The apron feeder sector gate

Technical field

The utility model relates to a kind of valve system of bulk material feeding device, belongs to mine feeding device technical field.

Background technology

Apron feeder commonly used at present mostly is equipped with bulkhgead gate, and bulkhgead gate is installed in the entrance of deflector chute, horizontal positioned, and during the feeder normal operation, gate is opened, and the material in the feed bin drops in the deflector chute; During the feeder maintenance, closed shutter, the blocking-up feed bin is to the passage of feeder, material is intercepted on gate, be convenient to the repair apparatus of staff's safe ready, during feeder work, also can pass through the material of the switching extent control whereabouts of gate, thereby the control feeding coal, but because material internal pressure and friction force, horizontal shutter opening and closing resistance is big, required propulsive effort is big, manpower can't satisfy, must be by means of hydraulic pressure or electric equipment, because propulsive effort is big, the required structural strength of gate is big, gate weight is big, as changing the apron feeder running velocity and change feeding coal with speed regulation device, then can increase equipment investment.

Summary of the invention

The purpose of this utility model provides a kind of apron feeder sector gate simple, in light weight, conveniently adjusted feeding coal that drives.

The utility model is realized by the following technical solutions:

A kind of sector gate of apron feeder, sector gate is installed in the deflector chute, sector gate connects by key and bearing pin, bearing pin is installed in the bearing pin bearing, the bearing pin bearing is fixed on the deflector chute side plate, bearing pin can freely rotate in the bearing pin bearing, and one side bearing pin stretches out the outer and actuating device connection of deflector chute side plate.The outside of deflector chute one side is provided with the registration device of sector gate position, location.

The drive form of sector gate has following several:

Sector gate is by manual driven, rocking arm is set outside deflector chute; rocking arm one end is installed the gate counterweight; the other end bores a knock hole; the rocking arm middle part connects by key and bearing pin, and the deflector chute side plate is provided with the locating plate of sector gate position, location, and knock hole is arranged on the locating plate; connect the location sector gate with the knock hole of locating dowel pin with knock hole on the locating plate and rocking arm one end.

Sector gate is by Driven by Hydraulic Cylinder, and hydraulic actuating cylinder is fixed on the deflector chute side plate by bearing, and rocking arm one end and hydraulic actuating cylinder are hinged, the other end and a side bearing pin fixed connection.For the location sector gate, outside the homonymy deflector chute, quadrant gear is set, connect by key and bearing pin.Be provided with on the deflector chute side plate and quadrant gear ingear detent mechanism, detent mechanism is controlled by small cylinder.

Sector gate is by motor driven, and motor is fixed on the deflector chute by flange, connects by a coupler and a side bearing pin, and its detent mechanism can be identical with the sector gate of Driven by Hydraulic Cylinder, also can adopt the location locking mechanism of other form.

Sector gate is driven by electric device, and electric device is fixed on the deflector chute by flange, connects by a coupler and a side bearing pin, and its detent mechanism can be identical with the sector gate of Driven by Hydraulic Cylinder, also can adopt the location locking mechanism of other form.

Working process of the present utility model is: start feeder, when feeding coal can not meet requirements, unclamp registration device, regulate the sector gate position, reach predetermined feeding coal, lock sector gate then.
