Specific implementation mode
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments
The present embodiment is related to a kind of weight dropper charge level indicator, to measure the height of materials in feed bin, as shown in Figure 1, the weight material
Position meter includes the hanger 1 being fixed at the top of feed bin, and rotation is set on the hanger 1 and both ends are respectively to the two-phase of the hanger
The shaft 21 that offside extends, the power output shaft motor 2 connected with one end of the shaft 21 are fixed relative to the motor 2
It is set in the other end winding wheel 3 of shaft 21.And rotation be located at hanger 1 and with the fifth wheel 4 of 3 homonymy of winding wheel.Further include
Limit switch 22 with the weight 5 of 3 homonymy of winding wheel and positioned at 2 side of motor.The traction rope 51 of the weight 5 is wound in winding
Wheel 3 is simultaneously sliding through fifth wheel 4.The support of material is accepted or be detached to the weight 5, and the motor 2 can be made to be rocked to different location, and
Limit switch 22 is triggered by motor 2 to be closed or disconnect.
In the present embodiment, hanger 1 be case shape, be fixed on the top of feed bin, one side be equipped with it is not shown in the figure can
The cover board of dismounting, cover board are detached from the installation convenient for each internal element, and 1 inside of hanger can be made to be in closed state after cover board installation,
To protect each element.Relative to dismountable cover board, mounting hole is offered on the side wall of 1 other side of hanger, and in mounting hole
Inside it is fixed with bearing.Shaft 21 passes through bearing, one end and the power output shaft of motor 2 to be connected, and winding wheel 3 is fixedly set in shaft
21 other end.
In the present embodiment, in the inside of hanger 1, it is equipped with the winding wheel 3 being sequentially connected with shaft 21.The winding wheel 3 can be
It is rotated under the drive of motor 2, the weight 5 that 51 end of traction rope is wrapped on winding wheel 3 is driven to rise or fall.For ease of measuring weight
The displacement distance of hammer 5, fifth wheel 4 is additionally provided in the inside of hanger 1, which can turn around the axis body being fixed on hanger 1
It is dynamic.The traction rope 51 of weight 5 is slided through the fifth wheel 4, drives the fifth wheel 4 to rotate, with the position turned over by measuring the fifth wheel 4
It moves, easily calculates the displacement distance of weight 5.
To prevent traction rope 51 from deviating from fifth wheel 4, the circumference of the fifth wheel 4 is equipped with flat " V " shape and is open.Traction rope
51 slide the bottom being open through " V " shape.To prevent traction rope 51 from skidding with fifth wheel 4, and cause measurement result inaccurate.At " V "
The lower circumference of shape opening is equipped with the linear fringe perpendicular to traction rope 51, to increase between traction rope 51 and fifth wheel 4
Frictional force.Meanwhile fifth wheel 4 is also set higher than winding wheel 3 in the present embodiment and is arranged, increase traction rope 51 to fifth wheel 4
Pressure further increases the frictional force between traction rope 51 and fifth wheel 4.
To measure the number of turns that fifth wheel 4 rotates, it is fixed with tachogenerator 41 on hanger 1, in the present embodiment, this tests the speed
Sensor 41 is reflecting light electric-type speed probe, coordinates the tachogenerator 41, at the bottom that the " V " shape of fifth wheel 4 is open
Multiple reflecting pieces are uniformly pasted on portion's circumference.The reflecting light electric-type speed probe can make the sensor when being irradiated to reflecting piece
Output variation, by calculate the sensor output variation number, the turnning circle of the fifth wheel 4 can be measured.And according to " V "
The perimeter of shape opening, can easily calculate the distance of the movement of weight 5.Photoelectric tachometric transducer has good in anti-interference performance,
Non-contact measurement, and the accurate advantage of measurement result.
In the present embodiment, as shown in Fig. 2, fixed there are one sleeve 6 in the bottom of hanger 1, traction rope 51 pass through sleeve 6 with
Weight 5 connects, to weaken the swing of traction rope 51.
Weight dropper charge level indicator in the present embodiment, when weight 5 is not affected by the supporting role of material, i.e., weight 5 not in contact with to
When material.The system that motor 2 and winding wheel 3 and weight 5 are formed is in an equilibrium state, and motor can be made to be in a position
It sets, motor 2 can be set at this time and be detached from limit switch 22, limit switch 22 is off.Material is touched in weight 5
Afterwards, there is supporting role to weight 5 due to material, and weight 5 is made to reduce the pulling force of motor 2, motor 2 can be rocked to separately at this time
One position can be arranged motor 2 and be contacted with limit switch 22, limit switch 22 is made to be in open state at this time.Therefore, can pass through
The contact of limit switch 22 turned on or off to determine weight 5 with material, and calculate with this height of material.Obvious,
When may also set up weight 5 and being not affected by the support of material, limit switch is in open state.Setting weight 5 is supported by material
When, limit switch is off.
To make limit switch 22 that there is better service life, 22 failure of limit switch, this implementation caused by avoiding dust
In example, which is contactless limit switch 22.To keep the detection to 2 present position of motor more accurate, limit
Switch 22 can also be to be arranged two in the both sides of motor 2 in addition to it can be one.Weight 5 is accepted or is detached from equal when the support of material
One of unlatching can be triggered, and another is disconnected.
For ease of measuring, control system, the control system and limit switch 22, motor 2 are equipped in the present embodiment, and survey
The control connection of fast sensor 41.
The weight dropper charge level indicator operation principle of the present embodiment is as follows：
First, weight dropper charge level indicator is in original state, and weight 5 is in elemental height, and the numerical value of the height is stored in control
In system.Motor 2 can be made to swing an angle under the action of 5 gravity of weight, limit switch 22 is closed.
Secondly, control system controls motor 2 and rotates, and controls the work of tachogenerator 41 simultaneously, until weight 5 and material
Contact, and by the supporting role of material.At this point, 2 backswing of motor, and acted on limit switch 22, so that limit switch 22 is opened.
Control system controls motor 2 and stops, and records the number of turns that the fifth wheel 4 that photoelectric sensor is measured rotates, and calculates traction rope
The distance that 51 distances slipped over namely weight 5 move.
Finally, the distance that weight 5 moves is subtracted by the numerical value of 5 elemental height of weight by calculating by control system, you can
Calculate existing height of materials.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
