Description
The present invention relates to a kind of measurement instrument, particularly utilize the blade rotary oscillation to control a kind of measurement instrument of powder shot-like particle position height.
Measure the instrument of powder shot-like particle position height, at present more common in the world is reciprocating type swinging, C5-D as Japanese public offering, C5-TA, C500EF and B3HA, models such as B3-X all are this type, principal feature is a poor sealing, mechanism wear is big, and action sensitivity is also relatively poor, and the pressure storehouse is inapplicable.Remove in addition, also have level meters such as tuning-fork type, condenser type and infrared ray, can not realize reliable detection and control also all because of the influence of dust.At this kind situation, the inventor has applied for the utility application of " resistance pendulum-type level meter " to Patent Office of the People's Republic of China on January 24th, 90, and be awarded patent right on November 28th, 90, this application provides a kind of tilting mechanism that utilizes to reach because of turning round the reciprocal disadvantages such as poorly sealed of bringing, seen apparent in view effect through the reality use, but still remain in production reality further to be improved and perfect, further improve structure, make it the state that reaches more satisfactory.
The object of the present invention is to provide and a kind ofly link by oscillating vane and yoke axle core, be engaged between the yoke of the left and right sides by one group of eccentric sheave device of driven by motor simultaneously, control motor action by starting microswitch, and carry out the signal transmission, make sharf not have revolution reciprocating action, only do the trace swing and make it to be easy to sealing, reach the purpose of manoeuvrable reasonable structural arrangement simultaneously.
It includes blade, blade seat, axle, forward and backward forked standard and left and right yoke and microswitch, motor, one end of axle is fixed on the core, the axle core passes forward and backward forked standard and left and right yoke is fixed as one, on the right yoke switch frame is housed, is fixed with microswitch on it, be fixed with pressing plate on the left yoke, motor plate in the casing is fixed on axle sleeve and the support, motor is fixed on it, and pulley is installed on the eccentric wheel on the motor shaft, and pulley places the shift fork slideway between left and right yoke two arms; Hang with spring between the described left and right yoke, limited post is fixed on the forward and backward forked standard, and left and right sides yoke is fixedly hinged on left and right yoke axle, and pressing plate is fixed therein yoke upper end, collides disconnected with the outstanding acting arm of switch.
Advantage of the present invention and effect are:
Because blade has been taked the swing principle, seal only produces slight twisting, because, for flexible seals, can reach tight leakproofness.Like this, when axle sleeve is fixed on the tested feed bin, blade and axle, after seal probeed into feed bin, axle was measured with the blade oscillating action, makes the isolation of movement and feed bin obtain reliable assurance.
Description of drawings is as follows:
Fig. 1 is an one-piece construction synoptic diagram of the present invention;
Fig. 2 unloads the right view of decapsidate for one-piece construction synoptic diagram of the present invention;
Fig. 3 is circuit theory diagrams of the present invention.
Below in conjunction with accompanying drawing, concrete structure of the present invention and principle are further described:
Referring to Fig. 1, Fig. 2, the present invention is by blade 1, blade seat 2, axle 3, seal hoop 4, seal 5, gland 6, plug 27, axle sleeve 26, preceding sealing gasket 7, bearing 8, support 9, rubber cushion 10, axle core 11(axle core 11 also can be integrated with axle 3), preceding forked standard and back forked standard 12 and 14, left and right yoke 13 and 28, pressing plate 15, end cap 16, microswitch 17, switch frame 18, pulley screw 19, spring 20, spring stack 21 also can be cancelled spring stack with 31(), pulley 22, eccentric wheel 23, motor 24, motor plate 25, left and right yoke axle 32 and 30, left and right yoke limited post 34 and 29 and some forked standard securing members (as 33,35) form.Blade 1 is installed on the blade seat 2, and blade seat 2 is fixed on axle 3 one ends, and axle 3 comes fit sealing with seal 5 by seal hoop 4 and gland 6 with 27 of plugs, and axle 3 passes axle sleeve by bearing 8 and stretches in the casing of being made up of support 9 and end cap 16.Show as Fig. 2, preceding forked standard 12 and 14 of the forked standards in back accompany left and right yoke 13 and 28, yoke axle 32 and 30 is fixed on 12,14 of forward and backward forked standards, left side yoke 13 is enclosed within on the left yoke axle 32, right yoke 28 is enclosed within on the right yoke axle 30, make corresponding yoke in 12,14 rotations of front and back forked standard freely around the yoke axle of correspondence, before and after left and right yoke limited post 34,29 also is fixed on forked standard 12 with 14, to guarantee left yoke 13 and right yoke 28 keeping parallelism under the pulling force effect of spring 20.14 keeping parallelisms of forked standard 12 and back forked standard before being to guarantee, forked standard 12 and 14 are fastening as 33,35 and so on some clench nails, and yoke axle 32,30 and yoke limited post 34,29 also have assurance forked standard 12 and 14 parallel and fastening effect concurrently.On the left and right yoke 13,28 spring stack 21,31 is housed, spring 20 hangs on the spring stack 21,31 and is pulled to left and right yoke 13 and 28 parallel.If cancellation spring stack 21,31 can directly hang over spring 20 on yoke 13 and 28.Forked standard 12 and 14 was fixed as one with left and right yoke before and after axle core 11 passed, and then axle core 11 was fixed on spools 3.Also can cancel a core 11 and axle 3 is directly fixed with forked standard 12 and 14.On the right yoke 28 switch frame 18 is housed, microswitch 17 is housed on the switch frame 18, left yoke 13 is fixed with pressing plate 15.Left and right yoke also can be with switch 17 and pressing plate 15 exchange assemblings because be symmetrical.Motor plate 25 in the casing is fixed on axle sleeve 26 and the support 9, motor 24 is fixed on the motor plate 25, eccentric wheel 23 is housed on the motor shaft, and pulley 22 is installed on the eccentric wheel 23 by pulley screw 19, and pulley 22 is placed left and right yoke 13 and the 28 shift fork slideways that form.
Assembling finishes, and circuit such as Fig. 3 are connected, and a, b insert power supply, if blade 1 is not subjected to resistance, axle 3 and blade 1 carry out the swing in the certain angle under motor 24 drives.When blade 1 is hindered by material, axle 3 is static with blade 1, and motor 24 drives eccentric wheel 23 and makes a certain yoke of pulley 22 compressings, supposes to oppress this moment left yoke 13, because the effect of right limit post 29 and right yoke axle 30, right yoke 28 is static with respect to axle 3, and left yoke 13 is subjected to pulley 22 compressings to be fixed on pressing plate 15 touch switch 17 on the left yoke 13 around left yoke axle 32 rotations, make switch 17 actions, 2 connections of b, c, 2 disconnections of b, d are sent the charge level signal and are cut off the power supply of motor 24.Charge level descends, and blade 1 suffered resistance disappears, and spring 20 makes two yokes recover parallel, and switch 17 resets, system recovery swing running status.If the right yoke 28 of pulley 22 compressings also produced similar action when blade 1 was obstructed, repeat no more.
