The momentary load that stream is unevenly, particulate matter generates in coal stream influences, and ensure that the accuracy of detection.
2. the data that the present invention acquires are transmitted to sample preparation machine control system, instruction is handled by it and sent, and sample preparation
Machine control system inherently has corresponding data-handling capacity, and the present invention, which shares sample preparation machine control system, keeps height intelligentized
Structure is simple, at low cost simultaneously；
3. rotary vane of the invention acquisition by have while coal miscarriage raw torque rotary speed data to coal stream integer with
The effect stirred evenly is integrated with the function of fairing, and uniform coal stream then has very greatly the precision of sample-preparing system and representativeness
Benefit.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is cross-sectional view of the invention.
Specific embodiment
The present invention will be further described below with reference to the drawings.
As shown in Figure 1 and Figure 2, the present invention include belt feeder main body 1, speed probe 6, conveyer belt 11, torque sensor 7,
Ultrasonic sensor 5, impeller 9 and sample preparation machine control system 8.1 top plate of belt feeder main body is equipped with hopper 2, in belt feeder main body 1
Equipped with conveyer belt 11, the both ends of the conveyer belt 11 are sleeved on roller 12, and roller 12 is horizontally set on belt feeder main body 1
Interior, the both ends of roller 12 are mounted on the side wall of belt feeder main body 1 by bearing.
Impeller 9 is installed in the belt feeder main body 1, the axis of impeller 9 perpendicular to conveyer belt 11, impeller 9 close into
Hopper 2 is arranged, and is equipped with multiple rotary vanes along axis direction in the shaft 91 of impeller 9.The top plate of the belt feeder main body 1
On the ultrasonic sensor mounting rack 3 of rod-like structure is installed, ultrasonic sensor mounting rack 3 is arranged perpendicular to conveyer belt 1, surpasses
It is uniformly arranged on sonic sensor mounting rack 3 and is not limited to three ultrasonic sensors 5 there are three ultrasonic sensor 5(, can lacked
, can also be with more than three in three), ultrasonic sensor mounting rack 3 is between hopper 2 and impeller 9.6 He of speed probe
Torque sensor 7 is mounted in the shaft 91 of impeller 9；Ultrasonic sensor 5, speed probe 6 and torque sensor 7 respectively with
Sample preparation machine control system 8 connects.It is semicircular sharf shield 4, blade that 1 top plate of belt feeder main body, which is equipped with section,
Axis shield 4 is located at turn around the outside of blade.
The present invention is in use, when coal is moved right with conveyer belt 11, pass through three supersonic sensings from hopper 2 into coal
When 5 radiation areas of device, the elevation information of coal sample several points is acquired and is transported to system by data line by ultrasonic sensor 5
Control prototype 8 obtains the cross section information of coal stream, and ultrasonic sensor 5 is fixed on ultrasonic sensor mounting rack 3, and
Setting is at 1 top of belt feeder main body, so that avoiding being buried by coal sample leads to data acquisition distortion.
