Description

Feed bin with charge level indicator

Technical Field

The application relates to the field of feed bins, in particular to a feed bin with a charge level indicator.

Background

In order to accurately master the material level of an aggregate bin and facilitate timely feeding, the existing aggregate bins are all provided with material level meters.

Present feed bin for storing aggregate, during the aggregate feeding, because feed position is close the feed bin middle part, consequently can pile up gradually in the position of the vertical projection of feeding, form the upwards protruding toper. When the aggregate is fed, the feeding position is located at the center of the lower end of the bin, the small particle part of the aggregate is in friction with the inner wall of the bin, the small particle aggregate is easily adhered to the inner wall of the bin, and the aggregate is lost in the middle of the bin, so that the aggregate forms an inverted cone.

In view of the above-mentioned related art, the inventor believes that in the above two cases, the height deviation of the aggregates in the bin measured by the level gauge is large.

Disclosure of Invention

In order to reduce aggregate measuring height's deviation in the feed bin, this application provides a feed bin with level gauge.

The application provides a feed bin with charge level indicator adopts following technical scheme:

the utility model provides a feed bin with charge level indicator, includes feed bin body, connects feed bin body upper end for the inlet pipe of leading-in aggregate, connects feed bin body lower extreme and is used for deriving the discharging pipe of aggregate and the valve of control discharging pipe load, this internal sweeping device who is used for sweeping the aggregate of installing of feed bin, sweeping device includes the connecting piece, is provided with a plurality of blades, drive connecting piece and blade along connecting piece axis pivoted motor, is used for placeeing the motor and only follows vertical direction sliding connection in the thing board of putting of feed bin body along connecting piece lateral wall circumference, connecting piece lower extreme fixed mounting has the charge level indicator, the measuring end of charge level indicator and the terminal surface parallel and level under the blade.

Through adopting above-mentioned technical scheme, the aggregate gets into this internal back of feed bin from the inlet pipe, opens the valve during the ejection of compact, and the aggregate is followed the discharging pipe and is derived downwards, and the aggregate that is located feed bin body middle part leaks downwards earlier, and the frictional force that is located between the aggregate of border position and the feed bin body inner wall is great difficult for dropping, consequently, the aggregate forms the back taper. During measurement, the motor is started to drive the blades to rotate, the position of the sweeping device is lowered, the aggregates at the edges are swept down, and the aggregates at the edges are filled to the middle until the aggregates are approximately filled and leveled. After the level indicator contacts the aggregate, the motor is closed, the material level at the moment is measured, and an operator can judge whether to feed according to measured data.

Preferably, the outer coaxial collar that is equipped with of connecting piece, each the blade all supports the collar inner wall, and moves towards sliding connection in collar along the collar, the collar lateral wall offsets with feed bin body inner wall, and follows vertical direction sliding connection in feed bin body inner wall.

Through adopting above-mentioned technical scheme, the in-process that the material device goes up and down along vertical direction is swept, and the collar is slided along feed bin body inner wall, compares in sweeping the material device and directly removes in the feed bin body, and setting up of collar has improved the stability that the material device removed of sweeping for the material device of sweeping only can follow vertical direction and remove, and the material effect of sweeping is better.

Preferably, one end, far away from the connecting piece, of each blade is fixedly provided with a sliding ball, the inner side wall of the mounting ring is provided with a sliding groove for the sliding ball to pass through along the circumferential direction of the inner side wall, and the sliding ball is connected to the inner wall of the sliding groove in a sliding manner along the direction of the sliding groove.

Through adopting above-mentioned technical scheme, connecting piece and blade pivoted in-process, the ball slides in the spout, and the blade is kept away from connecting piece one end because the dead weight, has the trend of sinking, has between blade and the collar after the relation of connection, and the stability in the blade motion process is better.

Preferably, the lower terminal surface of collar is seted up the scraping groove of intercommunication inside wall along its circumference, the scraping groove inner wall forms the scraping surface that is used for scraping feed bin body inner wall.

Through adopting above-mentioned technical scheme, the unloading in-process, aggregate and feed bin body inner wall friction, the easy adhesion of tiny particle aggregate is at feed bin body inner wall, again because the aggregate runs off from feed bin body middle part, therefore the aggregate forms the back taper. After the material scraping groove is arranged, aggregate adhered to the inner wall of the bin body is scraped by the mounting ring and is pushed flat by the rotating blade, and the material scraping groove has high practicability.

Preferably, the side wall of the blade close to one end of the bin body is fixedly provided with a material guide piece, and the material guide piece is an arc-shaped rod with an opening consistent with the rotating direction.

Through adopting above-mentioned technical scheme, connect the guide piece at the blade lateral wall, scrape the material in-process, the adhesion strikes guide piece tip earlier at the aggregate of feed bin body inner wall, and most aggregate is scraped to feed bin body middle part by continuous pivoted guide piece, reaches the effect of filling and leveling. After the material guide sheet is swept flat, the aggregate passing through the upper end of the material guide sheet is filled and leveled up again by the blades.

Preferably, a scraping included angle is formed between the blade and the horizontal plane and is a right angle.

Through adopting above-mentioned technical scheme, sweep the material in-process, if the blade pivoted speed direction is the acute angle with the contained angle between the blade, the blade scrapes the material in-process, has the blade to rotate in-process still to descend, when the blade sweeps, pushes down the aggregate, probably leads to the aggregate to be compacted, influences measuring result. If the included angle between the speed direction of blade rotation and the blade is the obtuse angle, the in-process that blade rotation and decline were gone on simultaneously scrapes the aggregate, leads to aggregate surface unevenness, still influences the measuring result.

Preferably, the storage plate is fixedly connected with a pull rope, and one end of the pull rope, which is far away from the motor, is dropped to the outer side of the storage bin body.

Through adopting above-mentioned technical scheme, the measurement in-process, user's accessible pulling stay cord, the position of adjusting the sweeping device for testing process and detection speed are controllable.

Preferably, one end of the pull rope, which is far away from the motor, is provided with a balancing weight.

Through adopting above-mentioned technical scheme, set up the balancing weight at the stay cord tip, can stretch or the speed that descends as required, change required balancing weight, when the quality of balancing weight is lighter than when sweeping the material device a little, sweep the slow whereabouts of material device, reach the purpose of sweeping the material.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the aggregates at the edge are pushed to the middle part by the sweeping device until the aggregates are approximately filled and leveled, and the material level meter is used for measuring the material height after contacting the aggregates.

2. The aggregate is pushed to the middle part of the feed bin body by the continuously rotating material guide piece, so that the filling effect is achieved.

3. The user can change the required balancing weight and adjust the position of the sweeping device according to the requirement of the descending speed.
