Abstract

The utility model discloses a cantilever governing belt balance, which is an electronic belt balance and is provided with a feeding strobe, a fixed charging hopper, a movable discharge hopper and a lever mechanism. A cantilever balance frame is fixed below the fixed charging hopper through a spring piece; the front segment of the cantilever balance frame is mutually connected with a lever through a hanging member; the lever is positioned on the pressure head of a sensor through a connecting level member. The balance has high metering accuracy, and is capable of being directly installed at the bottom of a material bin dispensing with an additional feeding device.

Description

Cantilever governing belt balance

The utility model relates to the belted electronic balance of a kind of batching and metering usefulness.

The proportioning belt scale that uses in commercial production at present mainly contains two kinds.A kind of is the speed governing single-idler electronic belt conveyor scale.It adopts the metering of single mount roller, and promptly sensor places the belt below, and the tension variation of belt can directly influence weighing precision.Another kind is a constant speed single swing arm type belt conveyer scale.This scale has adopted the method for single-cantilever scale continuous measurement, and weighing precision is higher, but must add electric and magnetic oscillation batcher feed in addition, to guarantee the constant of feeding coal, causes dust and noise pollution more serious.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of precision height is provided, in addition the cantilever speed governing belted electronic balance of addition materials device.

The utility model is achieved in that the scale body and also is provided with gate, stationary hopper, discharge bucket and leverage except that comprising cantilever scale frame, adjustable speed belt feeder, sensor.Gate is connected the feed bin bottom.Connect stationary hopper under the gate, leave the gap between the periphery of stationary hopper and discharge bucket.Respectively connect a boatswain chair in cantilever scale frame back segment both sides, be fixed on the below of stationary hopper by spring leaf.Two spring leafs are in the same plane, and the center line by stationary hopper.At cantilever scale frame leading portion, link to each other with the lever that is loaded on the gate below by suspender member, lever places on the sensor pressure head by connecting rod member.

The utility model adopts gate, and stationary hopper and mobilizable discharge bucket carry out feed, have replaced the serious electric vibrating feeder of dust noise pollution.Simultaneously owing to adopt the fulcrum of 2 spring leafs as the scale body, and with feed bin in the center of gravity of material be located along the same line, thereby can avoid the influence of the variation of material in the feed bin to measuring accuracy.In of the effect of scale body front end, the material gravity on the scale body is delivered on the sensor pro rata, thereby has guaranteed the precision of measuring conscientiously by lever.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the B of Fig. 1 is to view;

Fig. 4 is that the A of Fig. 1 is to view;

Fig. 5 is the left view of Fig. 4.

Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.

With reference to Fig. 1, Fig. 2, drive roll (8), automatic swabbing pig (9), wire rope (7), carrying roller (11), driven cylinder (15), bearing seat (14), idler stand plate (18), adhesive tape (19) are housed on the cantilever scale frame (10), regulate bolt (16), set nut (17).Adjust the degree of tightness of adhesive tape by regulating bolt (16).The drive unit of scale mainly is made up of the DC servo motor (21), tech-generator (20), shaft coupling (22), the worm reduction gear (23) that are installed on the gear frame (37).Drive roll input shaft (24) connection is connected in the endoporus of worm reduction gear (23).The gear frame of drive unit (37) is fixed on the cantilever scale frame (10) with pull bar (38), hex bolts (35), Connection Block (36).

With reference to Fig. 1, Fig. 3, Fig. 4, Fig. 5, in cantilever scale frame (10) back segment both sides boatswain chair (13) is housed, boatswain chair (13) is connected with bolt with discharge bucket (12), is fixed on the below of stationary hopper (2) by spring leaf (26).Spring leaf (26) constitutes the fulcrum of cantilever scale frame, and stationary hopper (2) leaves the 25-30 mm clearance with the periphery of discharge bucket (12).The leading portion of cantilever scale frame (10) links to each other with the lever (4) of meausring apparatus by two wire rope (7), lever (4) and steel pipe (29) are fixed as one, and cross-spring sheet (5) is screwed respectively on the hanger (6) below lever (4) and spiral gate (1).Sensor box (30) is fixed on the below of spiral gate (1), sensor (34) is housed in the case, steel pipe (29) passes in the middle of Sensor box (30), lever (4) is a fulcrum with cross reed (5), cantilever scale frame (10) is gone up material gravity,, be delivered to pro rata on the sensor (34) by being contained in the sensor pressure head (33) on the steel pipe (29), and, draw the actual flow of material with the electric signal of sensor input MICROCOMPUTER PROCESSING.
