Abstract
The utility model relates to a speed measuring device of a weight spiral materials-feeding machine suitable for materials transmission with low intensity, and is characterized in that the device is composed of a speed detection gear wheel, a magnetic speed detection probe, a display meter, a gear axis rack and a speed gear shaft, wherein the speed detection gear is arranged on the gear shaft rack, the speed detection gear is arranged on the speed gear shaft, the magnetic speed detection probe is vertically arranged in the place which is 1mm to 2mm far from the gear surface, and the magnetic speed probe and display meter are connected. The utility model can timely measure the instantaneous speed of materials with little speed measuring distortion.
Description
Technical field
The utility model relates to a kind of speed measuring device of weighing type spiral batcher of suitable case of low density loads conveying, belongs to Weighing type conveyor technical field.
Background technology
The speed measuring device that is extensive use of at present helical feed computation weigh system normally adopt gather the drive motor rotating speed as measuring parameter to determine material movement speed.Because mainly by the promotion of blade, material itself not only will overcome the friction force of cylindrical shell in the motion of material in the screw feeder, simultaneously at the motion or the generation movement tendency radially that radially also can produce radially because of friction with blade.Material comprises water cut in addition, the character of itself is not constant homogeneous, therefore the material in the screw machine cylindrical shell is actually and is doing very complicated variable motion, and weighing measurement requirement collection is the axial velocity of material output cylindrical shell instantaneous time, moment axial velocity when the rotating speed of therefore gathering drive motor can not show material output as measuring parameter, this makes metering produce very mistake, symmetry remakes very big influence, for addressing this problem, need real-time measurement be arranged to the instantaneous velocity of the material axially-movable of cylindrical shell outlet.
Summary of the invention
The purpose of this utility model provides a kind of speed measuring device that case of low density loads is carried the weighing type spiral batcher that the suitable case of low density loads of instantaneous velocity carries that can be fit to measure.
For realizing above purpose, the technical solution of the utility model provides a kind of speed measuring device of weighing type spiral batcher of suitable case of low density loads conveying, it is characterized in that, form by measure speed gears, magnetic survey speed probe, Displaying Meter, gear shaft support and measure speed gears axle, measure speed gears is located on the gear shaft support, measure speed gears is located on the measure speed gears axle, and magnetic survey speed probe is vertical at over against measure speed gears apart from the about 1mm-2mm of flank of tooth place, and fast probe of magnetic survey is connected with Displaying Meter.
Gear stand of the present utility model is fixed on the cylindrical shell below, the feeding cylindrical shell is stretched in the upper part of gear shaft measure speed gears, make the measure speed gears down motion of drive of material at the volley, holes probe is installed in the measure speed gears end portion over against teeth groove, motion by gear makes the magnetic field generating period variation of inducting record speed, other movement velocitys influences that radially reach of the material of compound movement are eliminated, only gathered the device of axially-movable speed.
The utility model has the advantages that the distortion of testing the speed is little, can measure the material instantaneous velocity immediately.
Description of drawings
Fig. 1 is the speed measuring device structural representation of the weighing type spiral batcher of suitable case of low density loads conveying;
Fig. 2 is the speed measuring device scheme of installation of the weighing type spiral batcher of suitable case of low density loads conveying.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, for being fit to the speed measuring device structural representation of the weighing type spiral batcher that case of low density loads carries, the speed measuring device that is fit to the weighing type spiral batcher that case of low density loads carries is made up of measure speed gears 1, magnetic survey speed probe 2, Displaying Meter 3, gear shaft support 4 and measure speed gears axle 5.
There is the measure speed gears axle 5 of auto-lock function to be installed on the gear shaft support 4, have auto-lock function the position can along carry cylindrical shell axially and the radiai adjustment relative position, measure speed gears 1 is installed on the measure speed gears axle 5, magnetic survey speed probe 2 is vertically mounted on over against measure speed gears 1 apart from the about 1mm-2mm of flank of tooth place, and magnetic survey is fast pops one's head in and 2 be connected with Displaying Meter 3.
During work, as shown in Figure 2, gear stand 4 of the present utility model is fixed on afterbody cylindrical shell 6 belows of weighing type spiral batcher, feeding cylindrical shell 6 is stretched in the upper part of measure speed gears 1, make the measure speed gears 1 down motion of drive of material at the volley, holes probe 2 makes the magnetic field generating period variation of inducting record speed by the motion of measure speed gears 1, adopt the minimum gear mechanism gearing of transmission distortion, and adopt self-locking device to prevent that reversing from taking place, velocity survey partly adopts the high magnetic survey quick-mounting of sensitivity to put, and can feed back the instantaneous axial velocity that the screw machine outlet material is carried accurately.
When testing the speed, full material drives the motion of the entire body front end undergear gear teeth in the cylindrical shell, and gear in the motion and magnetic survey speed probe constitute the magnetic field of a variation, by magnetic survey speed probe the electric signal that this field signal is converted into variation are presented at instrument.
