Description
Technical field
The present invention relates to a kind of measuring apparatus, particularly relate to a kind of Autoamtic bait putting measuring apparatus for deep-water net cage culture.Belong to deep-water net cage culture field.
Background technology
At present, China's deep-water net cage culture generally uses pellet, is a dead lift and throwing something and feeding substantially, increases labour intensity, also reduce work efficiency simultaneously.The feed granules density of different model and volume there are differences, and in bait throwing in process, in rotating blanking appts, feed packing constantly changes, and feed operational throughput also synchronously changes.Due to metering system with feed volumetric flow rate for metric results, cause feeding system to there is the shortcoming that feed metering is forbidden, error is larger.To measure through test, feedstuff feeding degree of error is about ± and 10%.Metering is inaccurate not only affects the precision and efficiency of throwing something and feeding, and the more important thing is the maximization affecting fish growth and culture benefit.
The fuel gauge device of current domestic device for feeding fish bait is mainly divided into helical feed formula, mechanical-vibration type, Electromagnetically vibrating, electromagnet turnover plate type, rotating disk quantitative, drawer type Quantitative dosing formula etc.Such device measuring principle is roughly Weighing type and constant volume type, uses middle meeting to be subject to the impact of the factors such as feed characteristics, mechanical vibration, VARIATION OF GRAVITY FIELD, therefore there is the coarse problem of feed metering when automatically throwing something and feeding.Along with deep water mesh cage is to maximization, the development of far-reaching sea, the Autoamtic bait putting equipment that Large Copacity, high precision, high-level efficiency, capacity of anti-storm are strong is developing direction from now on.
Summary of the invention
Technical matters to be solved by this invention, is just to provide a kind of deep water mesh cage Autoamtic bait putting measuring apparatus, and this measuring apparatus structure is simple, and accurately, good reliability, is not subject to the impact of feed characteristics and VARIATION OF GRAVITY FIELD in feed conveying and metering process in metering.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of deep water mesh cage Autoamtic bait putting measuring apparatus, is characterized in that comprising:
Housing, upper/lower terminal is respectively arranged with charging aperture, discharging opening;
Central rotating shaft, is vertically arranged in described housing;

Described swiveling wheel centre is provided with the diversion column of upwards convergent, and swiveling wheel upper surface also radial direction is provided with guide vane; Described swiveling wheel is arranged on the upper end of described central rotating shaft by key connecting, and between described inner housing top and described charging aperture.
Described torque-measuring apparatus is torque sensor, is located in the inner housing below swiveling wheel, and is connected with described central rotating shaft by elastic dowel pin shaft coupling.The output voltage of torque sensor is proportional to this turning moment, and by analog to digital conversion, analog quantity is converted to digital output.Torque sensor adopts resistance-strain type principle, realizes signal export by brush.
Described drive unit comprises drive motor and speed reduction unit, and is located at described shell body external bottom end; Described drive motor is three-phase AC asynchronous motor, and the output shaft of speed reduction unit is connected by shaft coupling with central rotating shaft.
Described rotation-speed measuring device is incremental encoder, is positioned at the below of torque sensor, is fixed on the output shaft of described speed reduction unit, the output shaft coaxial rotation of incremental encoder and speed reduction unit.The axle of incremental optical-electricity encoder turns around and can export fixing pulse, carries out computing obtain rotating speed by the output signal measuring incremental optical-electricity encoder.
Described charging aperture place is also provided with loading hopper.
Principle of work of the present invention is: feed granules enters in measuring apparatus from loading hopper, by the dispersion of vertical diversion column, in the groove between the guide vane of feed dispersion inflow swiveling wheel; Feed, with swiveling wheel driven rotary, to swiveling wheel movement outside under centrifugal action, is finally thrown off swiveling wheel, and then feed is along the free landing of shell body inwall, finally enters into discharging opening.In this process, feed is subject to the effect of centrifugal force, this power causes a motion by reaction moment, the moment of torsion of swiveling wheel central rotating shaft is recorded by torque sensor, and by analog to digital conversion, analog quantity is converted to digital output, thus draw the moment suffered by swiveling wheel, then the transient speed of the swiveling wheel recorded in conjunction with incremental optical-electricity encoder, just can obtain the flow of pellet.
Swiveling wheel rotates with central rotating shaft, and its rotational angular velocity is measured as ω; If unit quality of material m
iradial with speed v along swiveling wheel by swiveling wheel center
irelative to rotation crop rotation linear uniform motion; Moment of torsion depends on the angular velocity omega of swiveling wheel and the radial velocity v of particulate material
i; Within the t time, have i pellet by swiveling wheel, its individual particle quality is m
i, q
mfor the mass rate in the unit time, M
ifor the instantaneous torque that swiveling wheel is suffered when real work, it is as follows that it calculates derivation formula:
Both sides differentiate is obtained:
finally obtain: M=m × ω × R
2.In formula: M is the moment that rotation centripetal force produces measuring wheel center of rotation; M is the quality by swiveling wheel in the unit time; ω is the angular velocity of rotation of swiveling wheel; R is the radius of swiveling wheel.As can be seen from above formula, when angular velocity omega remains unchanged, M is directly proportional to pellet unit interval mass rate m, by the moment of torsion M that records and angular velocity omega, then can accurately obtain quality of the fodder flow.
Compared with prior art, advantage of the present invention is as follows:
(1) influence factor is measured few.Can find out that the characteristic of measuring accuracy to feed of this device, the factor such as blanking angle and falling speed are uncorrelated from formula.
(2) Real-time Feedback and control can be realized.Pellet measured value is dynamic change value, and the value measured by representative is instantaneous value, can realize the accurate control of signal Real-time Feedback to bait throwing in process control.
(3) this device does not relate to the impact of the Gravity changer such as mechanical vibration in pellet course of conveying, avoids the error effect that the statics measurement such as to weigh brings.
(4) because device is directly measured feeding quality, the product without the need to density and volume calculates, and therefore has nothing to do with the unit weight of feed, packing.
(5) structure is simple.General Pneumatic conveyer needs to install choke apparatus additional in discharge outlet, prevents air-flow upwards disturbance, the pellet of conveying is entered in conveying system smoothly.After pellet in this measuring apparatus enters swiveling wheel, the air-flow that blower fan used during conveying produces from the accuracy that can not affect measurement after entering measuring apparatus, and can block air stream upwards.Even if therefore there is reciprocal air-flow in measuring apparatus, also need not choke apparatus especially, greatly can simplify structure.
