Abstract
A hydraulic side-unloading coal feeder belongs to a coal feeding machine. The feeder is provided with hydraulic cylinders at two sides of a coal accommodating unit; the hydraulic cylinder is connected with a hydraulic pump station via an oil pipe; the hydraulic cylinder end part and a side-unloading plate connected with a hydraulic pump station are provided with an oil tank; the oil tank is connected with a coarse filter via an oil pipe; the coarse filter is connected with an oil pump via an oil pipe; the oil pump is also simultaneously connected with a motor and a fine filter; the motor is connected with a switch, and the fine filter is connected with a pressure gauge via a valve, and further connected with a manual change valve connected with the oil cylinder. The coal feeder has small volume, simple structure, flexible open and close operation, uniform coal placing, low maintenance, low cost, good seal, no air leakage, and less dust, which is beneficial to safety of mine.
Description
Technical field
The utility model relates to a kind of feeder, particularly a kind of hydraulic pressure side dump feeder.
Background technology
At present, the feeder that uses in the down-hole in colliery generally has two kinds, and a kind of is reciprocating type feeder; A kind of is palate formula gate coal feeder.Reciprocating type feeder drives by motor driving reducer again and cranks arm, and cranking arm is connected with reciprocating plate, back and forth coal supply; Palate formula gate coal feeder has a coal container made of bamboo, wicker, ratten, etc., and two palate mouths are arranged outside the coal container made of bamboo, wicker, ratten, etc., and the opening and closing by the palate mouth hinder, put coal.Sealing was bad when above-mentioned two kinds of devices were closed, and caused with Louing and to expect, to leak out.
Summary of the invention
The purpose of this utility model is the hydraulic pressure side dump feeder of good seal when a kind of closing will be provided.
Solve the technical scheme that its technical matters adopts: this device is formed by putting the coal container made of bamboo, wicker, ratten, etc., side dumping plate, hydraulic ram, hydraulic power unit, in two sides of putting the coal container made of bamboo, wicker, ratten, etc. hydraulic ram is arranged respectively, hydraulic ram is connected with hydraulic power unit by oil pipe, and the end of hydraulic ram is connected with the side dumping plate.
Hydraulic power unit has a fuel tank, and fuel tank is connected with coarse filter by oil pipe, and coarse filter is connected with oil pump by oil pipe, and oil pump also is connected with fine filter with electrical motor simultaneously, and electrical motor is connected with switch, and fine filter is connected with compression indicator by valve; Also be connected with hand change over valve simultaneously, hand change over valve is connected with oil cylinder.
Beneficial effect: owing to adopted such scheme, by hydraulic ram control side dumping plate, the control accuracy height of hydraulic ram, good seal when the side dumping plate is closed has solved technical problem to be solved in the utility model.This feeder small volume structure is simple, easy to operate, and open and close is flexible, and it is even to put coal, and maintenance capacity is little, and cost is low, because good seal performance is difficult for scurrying coal, is difficult for leaking out, is difficult for producing dirt, prevents management and keeps the safety in production useful the colliery is logical.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is the schematic diagram of the utility model hydraulic power unit.
The specific embodiment
Embodiment: this device is formed by putting the coal container made of bamboo, wicker, ratten, etc. 2, side dumping plate 3, hydraulic ram 4, hydraulic power unit, be connected with hydraulic ram 4 in two sides of putting the coal container made of bamboo, wicker, ratten, etc. 2, hydraulic ram 4 is connected with hydraulic power unit by oil pipe, the end of hydraulic ram 4 is connected with side dumping plate 3, is connected with skin block screw 5 in the bottom of putting the coal container made of bamboo, wicker, ratten, etc. 2.Hydraulic power unit has a fuel tank 21, fuel tank 21 is connected with coarse filter 22 by oil pipe, and coarse filter 22 is connected with oil pump 25 by oil pipe, and oil pump 25 also is connected with fine filter 26 with electrical motor 24 simultaneously, electrical motor 24 is connected with switch 23, and fine filter 26 is connected with compression indicator 27 by valve; Also be connected with hand change over valve 28 simultaneously, hand change over valve 28 is connected with oil cylinder 29 by oil pipe 30.
When need are put coal, 24 runnings of starting switch 23 electrical motors drive oil pump 25, (operation pressure is set according to the actual field needs) operation hand change over valve 28 when the certain operation pressure of compression indicator 27 indications, hydraulic oil injects oil cylinder 29 back cavities by oil pipe 30, oil cylinder 29 stretches out and promotes side dumping plate 3, open and put the coal container made of bamboo, wicker, ratten, etc. 2, begin to put coal.Cut off switch 23 this moment, and electrical motor 24 and oil pump 25 are no longer worked, and enter to put the coaly attitude.
When coal bunker did not have coal, starting switch 23, electrical motor 24 drove oil pump 25 work, reverse operation hand change over valve 28, and hydraulic oil injects oil cylinder 29 ante-chambers by fuel feed pipe 30 tunnel, and oil cylinder 29 shrinks, and side dumping plate 3 and then shrinks, and closes and puts the coal container made of bamboo, wicker, ratten, etc. 2.
