During ore deposit produces, belt conveyor becomes with the feature such as its simple in construction, installation and transportation convenience, continuous portion discontinuous haulage, superior performance
Crucial transporting equipment for mine hoisting production capacity.
In industrial automation produces, in order to add up weight of material and control the requirement of conveying capacity, need in course of conveying
Material measures.Due to the geographical environment that colliery is special, belt conveyor is in high temperature, humidity, the environment of many dust, electricity
Resistance strain gauge transducer works in the environment, can affect its insulating properties, and life-time service can produce creep and reduce its stability,
Thus cause the result weighed inaccurate.
Summary of the invention
The present invention is contemplated to solve problem above, it is provided that a kind of adapt to coal mine environment and stability and the highest use of weighing
In the continuous weighting system of coal mine leather belt conveyer, thus adapt to the needs of development.
In order to achieve the above object, the present invention provides a kind of continuous weighting system for coal mine leather belt conveyer, including cylinder of weighing,
The top of described cylinder of weighing hangs on one end of lever, and the center of lever is fixed on a bearing formation fulcrum, another of lever
End is hung with the Weighing body for balance weighing cylinder weight；The bottom of described cylinder of weighing is connected with buoyancy sensor by dowel steel,
Realization is weighed cylinder and the upper and lower synchronous shift of buoyancy sensor；Connect below the bottom discharging opening of described cylinder of weighing that to tilt to belt defeated
The blow tank on machine belt, described discharging opening is sent to be provided with valve.
Further, described Weighing body includes box body and the multiple pouring weights being movably arranged in box body.
Further, described buoyancy sensor includes cylinder body, the liquid of weighing being located in cylinder body, weigh float and magnetic core, described
Being provided with balancing stand in the middle of cylinder body, described balancing stand includes the annulus centered by the axle center of float of weighing, and described annulus periphery is uniform
Be laid with round pin, the outer face of described round pin be arc and and the inwall of cylinder body between zero contact；Described float of weighing is along annulus
Central axis moves；Described magnetic core outfan is electrically connected with controller.
Further, in order to make balancing stand stable, described round pin is three.
Further, described valve is electrically operated valve, and the outfan of described controller electrically connects with electrically operated valve.
The present invention uses lever principle and buoyancy sensor that the material of course of conveying is carried out check weighing, is claimed by the material of constant weight
Get well and passed on conveyer belt by blow tank；Then detection signal is transferred to controller and shows by buoyancy sensor in time
Show.
Described the method have the advantages that
1, use buoyancy sensor due to native system, colliery special environment does not interferes with the accuracy of its detection, and
Also the potential safety hazard will not brought by wet environment.
2, the float of weighing of the buoyancy sensor in native system is the linear motion carrying out vertical direction in balancing stand, it is to avoid
Weigh the friction between float and cylinder body, improve accuracy, reliability and the rapidity of detection.
3, native system uses lever principle that cylinder of weighing is suspended on one end of lever, uses box body at its other end and places box body
Interior pouring weight, can regulate weight to be weighed at any time, have certain adjustability.
Accompanying drawing explanation
The present invention is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is present configuration schematic diagram；
Fig. 2 is the buoyancy sensor side view in the present invention；
Fig. 3 is the top view of Fig. 2.
In figure: 1-Weighing body, 2-lever, 3-bearing, 4-weighs cylinder, 5-electrically operated valve, 6-blow tank, and 7-floats
Force transducer, 71-weighs float, 72-cylinder body, 73-magnetic core, and 74-weighs liquid, 75-annulus, 76-round pin, and 8
-dowel steel.
Detailed description of the invention
As it is shown in figure 1, a kind of continuous weighting system for coal mine leather belt conveyer, including cylinder 4 of weighing, described in weigh cylinder 4
Top hang on one end of lever 2, the center of lever 2 is fixed on a bearing 3 formation fulcrum, the other end of lever 2
It is hung with the Weighing body 1 for balance weighing cylinder weight；The bottom of described cylinder 4 of weighing is by dowel steel 8 and buoyancy sensor 7
Connect, it is achieved weigh cylinder 4 and buoyancy sensor about 7 synchronous shift；Connect below the bottom discharging opening of described cylinder 4 of weighing and have
Tilting to the blow tank 6 on belt of belt conveyor, described discharging opening is provided with electrically operated valve 5.
Further, described Weighing body 1 includes box body and the multiple pouring weights being movably arranged in box body, can adjust according to the quantity of pouring weight
The requirement that joint is weighed.
As shown in Figure 2,3, buoyancy sensor 7 includes cylinder body 72, the liquid 74 of weighing being located in cylinder body 72, float of weighing
71 and magnetic core 73, is provided with balancing stand in the middle of described cylinder body 72, described balancing stand includes centered by the axle center of float 71 of weighing
