FIG. 2 is a cross-sectional view of the mixing device material metering system of the embodiment of FIG. 1 with the calibrant in a set position. FIG. 3 is a cross-sectional view of the mixing device material metering system of the embodiment of FIG. 1 with calibrant disengaged from the cap body. As shown in fig. 1, 2 and 3, the material metering system of the stirring device comprises a base 20; the measuring hopper is used for containing materials to be measured; the weighing scale 10 is connected with the base 20 and is connected with the weighing hopper; and the automatic calibration object taking and placing device is used for taking the calibration objects off the metering hopper or placing the calibration objects on the metering hopper.

The scheme can obviously improve the convenience degree of the calibration of the metering scale 10, does not need an operator to manually contact and carry the weights, greatly improves the labor efficiency and increases the safety. Moreover, because the weight does not need to be manually carried by an operator, the time consumption problem of manually carrying the weight does not need to be considered, the interval of the calibration weigher 10 is shortened, the frequency of calibrating the weigher 10 is increased, the accuracy of the weigher 10 is improved, and the production quality of concrete is improved.

The weighing scale 10 is suspended through the beam part 21, and the automatic calibration object taking and placing device is installed, so that the space around the weighing scale 10 can be fully utilized, and the whole volume of the material metering system of the stirring equipment is reduced. The calibration object is arranged between the metering hopper and the automatic calibration object taking and placing device, and the taking and placing of the calibration object are facilitated. Meanwhile, the distance between the lower surface of the electromagnet 30 and the upper surface of the weight serving as the calibration object can be shortened, so that the action time is favorably shortened, and the total time consumption of scale calibration is reduced.
In one possible implementation, the automatic calibrator taking and placing device includes a calibrator lifting assembly, and the calibrator lifting assembly is used for being connected with the calibrator and driving the calibrator to lift and separate from the metering hopper. It should be noted that the calibrant lifting assembly herein may not be absolutely vertically lifted, for example, a movement that forms an angle smaller than 20 ° with the vertical line may be considered as belonging to the lifting category, as long as the calibrant can be driven to separate from the weighing hopper and put on the weighing hopper.
The lifting mode is adopted to separate the calibration materials from the metering hopper, the metering hopper does not bear the weight of the calibration materials any more, the calibration materials can be separated from the metering hopper only by lifting a small distance, the action stroke is short, the action time can be shortened, and the operation efficiency is improved.

Besides, the electromagnet is electrified to absorb the calibration object, other moving parts are not needed besides the calibration object, and therefore shaking of the material metering system of the stirring equipment can be reduced, and metering accuracy is improved.

When the calibration object needs to be put down, the driving mechanism drives the clamping jaw air cylinder to descend, and at the moment, the clamping jaw air cylinder is in a state of clamping the calibration object; after the calibration object is placed on the metering hopper, the clamping jaws of the clamping jaw air cylinders release the calibration object; the driving mechanism drives the clamping jaw cylinder to ascend, and the clamping jaw cylinder cannot clamp the calibration object and then ascend; the calibrant is placed on the weighing hopper, and the weight of the scale 10 includes the weight of the calibrant.

By placing the calibration objects on the cover body 51, the lateral dimensions of the weighing hopper can be reduced compared to solutions in which calibration objects are placed elsewhere, which is advantageous for reducing the overall dimensions of the material weighing system of the mixing plant. Moreover, the automatic calibration material taking and placing device can be arranged above the cover body 50, so that the calibration material can be lifted or placed down conveniently in a lifting mode, the lifting or placing process of the calibration material is easier to realize, interference with other positions of the metering hopper can be avoided in the taking and placing process of the calibration material, and collision on the metering hopper is reduced.
In another possible implementation, the calibration object may be placed on the bucket body 60, for example, a box with an opening facing upward may be provided on the outer side of the bucket body 60, the calibration object may be vertically taken out or put down from the box, or the angle of taking out or putting in the calibration object may be not more than 20 ° from the vertical line.
In one possible implementation manner, the placing positions 52 are symmetrically arranged relative to the connecting portion of the cover body 51 connected to the weighing scale 10, and the automatic calibration material taking and placing devices are arranged in one-to-one correspondence with the placing positions 52.

That is, in the present embodiment, the number of the automatic calibration object placement devices is two, and the two automatic calibration object placement devices are symmetrical with respect to the weighing scale 10.
The placing position 52 is arranged at the symmetrical position of the connecting part of the cover body 51, which is connected with the metering scale 10, after the calibration object is placed at each time, the metering hopper still can keep the original suspension posture, the weighing accuracy of the metering scale 10 is improved, the difference value between the measured value and the actual weight of the metering scale 10 can be reduced as much as possible, and therefore accurate scale calibration is facilitated.
In another possible implementation, the placement locations 52 may not be symmetrical with respect to the connection of the cover body 51, such that placing weights may cause the weighing hoppers to tilt, but such an arrangement is theoretically possible because the total weight weighed by the scale 10 is still that weight, as long as the weighing hoppers are not in contact with, and not under the force of, other components. Alternatively, three or four placing positions 52 may be provided on the cover body 51, and correspondingly, three or four automatic calibrant pick-and-place devices may be provided.
In one possible implementation, the placing position 52 is provided with a limiting cylinder 53, and the limiting cylinder 53 comprises a limiting cylinder wall which extends upwards from the cover body 51.
Set up spacing section of thick bamboo 53, can put down or the in-process of release at the calibration thing, lead to the orbit and the gesture of calibration thing for the calibration thing can be just with the bottom surface fall on the lid body 51 place the position 52 in, avoid the gesture and the position of calibration thing to change, thereby as far as possible unify the influence of weighing to the measuring hopper weight after releasing the calibration thing at every turn, with the accuracy that improves the school balance.
In another possible implementation, the placement location 52 may be a recess provided on the cover body 51, and the size of the recess is the same as the calibration object or slightly larger than the size of the bottom surface of the calibration object. The periphery of the placement site 52 may smoothly transition with the lid body 51 and may slide into the center of the recess for placement in a more accurate position even if the calibrant is placed with a slight offset.
In another possible implementation, the automatic calibrator handling device may not correspond to the placement positions 52 one-to-one, for example, the calibrator may have a ring shape, and the ring shape may be a circular ring shape or a zigzag shape. The automatic calibration object taking and placing devices are arranged in two numbers, the two automatic calibration object taking and placing devices are symmetrically arranged relative to the metering scale 10, and when the calibration object needs to be lifted or put down, the two automatic calibration object taking and placing devices simultaneously act to lift or put down the annular calibration object.
In one possible implementation, the number of the automatic calibration material handling devices is multiple, and the automatic calibration material handling devices are symmetrically arranged relative to the connection portion of the weighing hopper and the weighing scale 10.
The automatic calibration material taking and placing device is symmetrically arranged relative to the connecting part of the metering hopper and the metering scale 10, so that the influence of the load when the calibration material falls on the placing position 52 on the balance of the metering hopper is reduced when the calibration material is released simultaneously, the metering hopper can be recovered to be stable as soon as possible, and the weight of the metering hopper can be accurately obtained.
In another possible implementation, the weighing scale 10 may not be in a suspended form, and may be disposed at the bottom of a weighing hopper, for example, the weighing scale 10 may be of a pressure-sensitive type. The automatic calibration material loading/unloading device may be provided on the beam portion 21, and the weight of the weighing hopper may be changed by loading or unloading the calibration material onto or from the cover 50 of the weighing hopper.
In one possible implementation manner, the method further includes: a control device, the control device comprising: and the controller is electrically connected with the electromagnet 30.
Specifically, the controller is configured to control whether the electromagnet 30 is energized or not, and for example, the program may be set to perform automatic scale calibration once after weighing a certain number of times, and for example, may perform automatic scale calibration once after weighing 10 times, 100 times, or 1000 times. In addition, the controller may also receive a weight information signal weighed by the scale 10.
If the weights on the weighing hoppers are lifted separately, the following problems arise: part of the weights are lifted first, and the weighing hopper does not bear the weight of the part of the weights any more; the weight of other weights is still borne by the weighing hopper, so that the weighing hopper can incline towards the direction of the weight; when the weight lifted later is lifted, the weighing hopper will swing in a pendulum manner, so that the weighing scale 10 cannot accurately weigh the weight of the weighing hopper in time.
The controller is electrically connected with the electromagnet 30, and the electromagnet 30 is controlled to be electrified or not through the electric signal, so that the action synchronism of the electromagnet 30 can be improved, the weight of the weight is almost not borne by the metering hopper at the same time, the shaking is reduced or even possibly eliminated, and the accurate weight of the metering hopper can be measured more quickly by the metering scale 10.
In one possible implementation, the control device further includes: and the alarm is electrically connected with the controller.
The alarm is arranged, so that after the automatic calibration of the metering scale 10 finds that the precision of the metering scale 10 is low, the alarm can automatically give an alarm to prompt an operator that the weighing of the metering scale 10 is inaccurate and other operations are required.
In one possible implementation, the control device further includes: and the storage is electrically connected with the controller.
The memory is arranged, so that historical check records can be stored, and the weighing condition of the metering scale 10 can be traced conveniently in the follow-up process.
The operation principle of the embodiment is as follows:
when the scale needs to be calibrated, the additive is firstly injected into the metering hopper, and the metering scale 10 weighs the weight m of the additive1(ii) a At this time, the calibration object is separated from the cap body 51, and this state is shown in fig. 3.
When the electromagnet 30 is operated to change the state of the calibration object, for example, the calibration object can be released, and the calibration object is guided by the stopper cylinder 53 and falls on the placement position 52, so that the weight of the calibration object is also borne by the weighing scale 10, and the weighing scale 10 measures the weight m of the weighing hopper in this state2(ii) a The state at this time is shown in fig. 3.
M is to be1And m2Subtracting the two weights to obtain the weight difference Deltam, where Deltam is | m1-m2L. Δ m is compared to the weight m of the calibrator.

And if the deviation between the delta m and the m exceeds a preset range, alarming. Furthermore, the control device may comprise a memory in which the results of each measurement can be stored, facilitating subsequent traceability and analysis of the recipe. In addition, because the time required by the material metering system of the stirring equipment for calibrating the scale each time is greatly reduced, the frequency of calibrating the scale can be greatly improved, the original calibration once every quarter can be changed into the calibration after weighing for every time or dozens of times, and even the calibration can be carried out after weighing every time, so that the problems can be found in time, and the generation of unqualified products is avoided.
