Abstract
The utility model relates to an anti-rotating material level sensor, and belongs to the field of industrial control. The anti-rotating material level sensor comprises a back-end induction device (1) and a detecting rod (3) connected with the induction device (1), and is characterized in that a detecting claw (5) is arranged at the front end of the detecting rod (3), the detecting claw (5) comprises a left thin rod and a right thin rod, wherein the left thin rod and the right thin rod are parallel to each other, and the front end of the left thin rod and the front end of the right thin rod turn outwards by 90 degrees and stretch out. The anti-rotating material level sensor adopts the detecting claw and a pressure-bearing check block, and due to the fact that the detecting claw is mainly formed by the thin rods, the pressure-bearing material gravity phenomenon of an existing material level detecting sheet is not prone to occurring, and the detecting rod cannot be deformed and damaged to cause decline of sensitivity of the sensor. The pressure-bearing check block can bear the pressure of materials, pressure formed on the material level sensor by the action of the gravity of the materials is reduced, and deformation and damage of the detecting rod cannot be caused. A pressure-bearing problem cannot occur to the detecting claw, resistance toque of the materials is enlarged, and detection precision is improved.
Description
Technical field
The utility model relates to a kind of level sensor, relates in particular to a kind of resistance and revolves level sensor.
Background technology
In production line or material flows automation process, the control of the material level of feed bin is necessary part in the control automatically.The level sensor of present widely used feed bin is that level sensor is revolved in resistance, namely be that the rear end has induction installation, front end is the material-height exploring sheet that links to each other with induction installation, described material-height exploring sheet is the thin slice of the level that can rotate around intermediate rotary shaft, when thin slice rotates, run into resistance, the induction installation of rear end can judge whether to determine the height of material level etc. for running into material according to the turned position of resistance size and thin slice.
In the practice, resistance is revolved the material-height exploring sheet of level sensor front end owing to be horizontal sheet, when feed bin windrow or blanking, sometimes material can drop on this material-height exploring sheet, causes sensor to send back error signal, influences the control system misjudgement, the production control signal that may make the mistake, influence is produced; And because the position that the material-height exploring sheet stops is at random, sometimes the material-height exploring sheet just stops at horizontal level, increase with material level, will act on because of the gravity of material on the material-height exploring sheet and to form pressure and cause the feeler deformed damaged that is connected with induction installation, the judgement that level sensor is revolved in the influence resistance, therefore the degree of accuracy of sensor can be affected, and the position signalling that returns is no longer accurate, also can relatedly have influence on the degree of accuracy of The whole control system.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of resistance and revolves level sensor, solves present sensor and can send back error signal and influence the defective that control system misjudgement and the decline of sensor degree of accuracy influence the degree of accuracy of control system.
Technical scheme
Level sensor is revolved in a kind of resistance, comprises the induction installation and the feeler that links to each other with induction installation of rear end, it is characterized in that: at described feeler front end probe claws is set, and two parallel thin bars about described probe claws comprises, thin bar front end turns to the outside to stretch out.
Described induction installation is connected with the material-height exploring sheet by feeler, the tie point of described material-height exploring sheet and induction installation is positioned at material-height exploring sheet center, in described material-height exploring sheet the place ahead probe claws is set, described probe claws is the thin pawl that stretches out forward that is arranged on described material-height exploring sheet two ends.
Be provided with the tectate pressure-bearing block in inclined-plane above described probe claws in the feed bin, the front end of described probe claws stretches out the scope of described pressure-bearing block.
Described pressure-bearing block is arranged on described probe claws top 20 centimeters.
Described probe claws is the Metallic rod that is welded on described material-height exploring sheet two ends, and the Metallic rod front end turn 90 degrees outward and stretches out.
Beneficial effect
Resistance of the present utility model is revolved level sensor and is adopted probe claws and pressure-bearing block, because probe claws mainly is made up of thin rod, be not prone to the phenomenon of the pressure-bearing material gravity of existing material-height exploring sheet, then can not cause the feeler deformed damaged, and then cause the sensitivity of sensor to descend, and the pressure-bearing block can be born the pressure of material, the gravity that reduces material acts on the material-height exploring sheet and forms pressure, can not cause the feeler deformed damaged yet, and the pressure-bearing problem of foil detector neither can appear in probe claws, increase the resistive torque of material again, improved detection accuracy.
Description of drawings
Fig. 1 is the main synoptic diagram of looking in the feed bin of the present utility model.
Fig. 2 is A-A direction schematic side view among Fig. 1.
Fig. 3 is the utility model enlarged diagram.
Wherein: 1-induction installation, 2-material-height exploring sheet, 3-feeler, 4-pressure-bearing block, 5-probe claws, 6-windrow.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
Shown in attached Fig. 1 and 2, level sensor is revolved in a kind of resistance, comprises the induction installation 1 and the feeler 3 that links to each other with induction installation 1 of rear end, at described feeler 3 front ends probe claws 5 can be set directly, two parallel thin bars about described probe claws 5 mainly comprises, thin bar front end turn 90 degrees outward and stretches out.
At the induction installation 1 of existing sensors and the place ahead of the material-height exploring sheet 2 that is connected by feeler 3 probe claws 5 is set exactly in addition, described probe claws 5 is for being arranged on the thin pawl that stretches out at described material-height exploring sheet 2 two ends forward, as shown in Figure 3.Described probe claws 5 is for being welded on the Metallic rod at described material-height exploring sheet 2 two ends, Metallic rod adopts 10-20 centimetre reinforcing bar, the Metallic rod front end turn 90 degrees outward and stretches out 5-10 centimetre (determining length according to surveying material characteristic), to increase the resistive torque of material, improves detection accuracy.
Can be provided with the tectate pressure-bearing block 4 in inclined-plane above described probe claws 5 in the feed bin, the front end of described probe claws 5 stretches out the scope of described pressure-bearing block 4.Described pressure-bearing block 4 is arranged on described probe claws 5 tops 20 centimeters.
Described pressure-bearing block 4 covers material-height exploring sheet 2 fully, and pressure-bearing block 4 can be born the pressure of material, and the gravity that reduces material acts on the material-height exploring sheet 2 of sheet shape and forms pressure, thereby can not cause feeler 3 deformed damaged.And the direct scheme that probe claws 5 is set at feeler 3 front ends, because probe claws 5 mainly is made up of thin rod, be not prone to the phenomenon of pressure-bearing material gravity of the material-height exploring sheet 2 of sheet shape, when increase probe claws 5 length guarantee enough moments of torsion, also can adopt the existing foil detector 2 of hollow out or existing foil detector 2 is directly changed into the probe claws 5 of many fine steel ribs, at this moment pressure-bearing block 4 can arrange.
