Good operational effect.
Utility model content
Therefore, one of the purpose of this utility model is to provide a kind of rice husk spiral on-line metering weighing device, to solve
Rice husk is due to density too small the problem of being difficult precise in the prior art.
In order to achieve the above object, the utility model provides a kind of rice husk spiral on-line metering weighing device, which exists
Line metering and weighing device includes: screw conveyor, and screw rod and flight are provided in the screw conveyor, and one end of the screw rod connects
It is connected to motor；A plurality of metal blocks, on the circumference for the output shaft which is evenly arranged in the motor, the output
Axis rotation drives a plurality of metal block rotations；Close to switch, the neighbouring output shaft is arranged, and the position and fortune close to switch
The metal block of row to detection position is corresponding；Processing module is electrically connected close to switch with this and receives this close to switch output
Sensing signal, which is counted according to the sensing signal, the parameter of the screw conveyor and default calculation procedure
The weight of the rice husk of screw conveyor conveying is obtained according to processing.
As optional technical solution, this is close to the position and operation switched to the distance between the metal block for detecting position
For 3-5mm.
As optional technical solution, the parameter of the screw conveyor includes screw pitch and screw diameter.
As optional technical solution, which further includes counting unit, in the counting unit statistical unit time
The close switch and the close number of metal block.
As optional technical solution, which is connected with display screen.
As optional technical solution, which includes PLC controller.
Compared with prior art, the utility model is turned by calculating feed auger close to the number of switch detection metal block
Speed goes out the volume conveyed in the unit time by revolution speed of screw and known screw pitch, diameter calculation, in conjunction with the densitometer of rice husk

The advantages of about the utility model and spirit can be described in detail by utility model below and institute's accompanying drawings obtain into
The understanding of one step.
Detailed description of the invention
Fig. 1 show the schematic diagram of rice husk spiral on-line metering weighing device according to the present utility model.
Specific embodiment
Referring to Figure 1, Fig. 1 show the schematic diagram of rice husk spiral on-line metering weighing device according to the present utility model.
The utility model provides a kind of rice husk spiral on-line metering weighing device, which includes spiral
Conveyer, a plurality of metal blocks 1, close switch 2 and processing module 3.Screw rod and flight, spiral shell are provided in screw conveyor
One end of bar is connected with motor, and a plurality of metal blocks 1 are then evenly arranged on the circumference 41 of the output shaft 4 of motor, motor
The rotation of output shaft 4 is to drive a plurality of metal blocks 1 to rotate.
Wherein, it is arranged close to switch 2 adjacent to output shaft 4, and close to the position of switch 2 and runs to the metal for detecting position
Block 11 is corresponding.Processing module 3 is then electrically connected with close switch 2 and receives the sensing signal exported close to switch 2, processing module
3 is defeated further according to sensing signal, the parameter of screw conveyor and default calculation procedure progress data processing acquisition screw conveyor
The weight of the rice husk sent.
Wherein, to guarantee to sense effect, operation is to the metal block 11 of detection position and close to the gap between switch 2 to connect
Nearly switch 2, which can collect safely sensing signal, to be advisable, such as the metal block 11 of position is extremely detected close to the position of switch 2 and operation
The distance between 5 be 3-5mm.
In addition, the parameter of above-mentioned screw conveyor includes screw pitch and screw diameter.
Moreover, processing module 3 further includes counting unit 31, when counting unit 31 is to statistical unit in present embodiment
Interior close switch 2 and the close number of metal block 1.And the more precision of quantity of metal block 1 are higher, but if too close then meeting again
Adjacent metal block is caused to influence each other with close to switch, so metal block 1 is preferably, for example, 12.Such as it is with 12 metal blocks
, in 4 rotation process of motor output shaft, metal block is corresponding close to once with close to switch 2, and close switch 2 will be once interior
Bilge vortex generates, and issues a pulse signal.When the every rotation of the output shaft 4 of motor one week, 12 pulses will be issued close to switch
Signal.If turning 6 turns per minute, 6 × 12=72 pulses, frequency is 72/60=1.2HZ, can be obtained turning for screw conveyor
Speed, screw pitch and screw diameter in conjunction with screw conveyor can calculate the body of unit time internal screw conveyer conveying
Product, finally in the weight for combining the density of rice husk that can calculate the rice husk that screw conveyor conveys.
Wherein, processing module 3 further includes PLC controller 32, and PLC controller 32 is connect with counting unit 31.Using being equipped with
The PLC controller of default calculation procedure, the rice husk of screw conveyor conveying can be calculated by the default calculation procedure of setting
Weight.
Moreover, processing module 3 is also connected with display screen in present embodiment, on a display screen convenient for data processed result
It can intuitively show.
In conclusion the utility model is led to by calculating feed auger revolving speed close to the number of switch detection metal block
It crosses revolution speed of screw and known screw pitch, diameter calculation goes out the volume conveyed in the unit time, calculated in conjunction with the density of rice husk
The weight (as practical rice husk inlet amount) of the rice husk of screw conveyor conveying, so that realizing can be quasi- in gasification furnace production process
Really measure rice husk inlet amount.
By the above detailed description of preferred embodiments, it is intended to more clearly describe the feature of the utility model and essence
Mind, and not the protection scope of the utility model is limited with above-mentioned disclosed preferred embodiment.On the contrary,
The purpose is to wish to cover various changes and have the guarantor for being arranged in the claim that the utility model to be applied of equality
