There are two vibrating screens, and there are correspondingly two magnet cleaners and rotary distributors, and each rotary distributor is connected to a part of each storage bin.

Some storage bins are connected with two rotary distributors at the same time.

Each screw conveyor is connected with a storage bucket, and a pneumatic gate is arranged under the storage bucket.

A batching scale for automatic weighing is arranged in the storage hopper.

The utility model provides an automatic feed batching device, which realizes the automatic preparation of raw materials by automatically controlling the speed or number of rotations of the screw conveyor, and is suitable for the preparation of raw materials with large preparation volume and low precision requirements, such as corn and wheat bran. , bran, rapeseed cake, bean cake, bean dregs, fruit dregs and other raw materials. As for the preparation of fine materials, it can be prepared in the subsequent process by accurate weighing. The utility model greatly improves the preparation of raw materials. Speed, and the control is very convenient and reliable, even if the batching scale fails, it will not affect the normal production.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Figure 1 is a schematic diagram of the overall structure of the utility model.

Fig. 2 is a schematic side view of the utility model.

In the figure: vibrating screen 1, magnet slag remover 2, rotary distributor 3, storage bin 4, screw conveyor 5, storage bucket 6, pneumatic gate 7, frequency conversion motor 8.

Detailed ways

As shown in Figures 1 and 2, a feed automatic batching device includes a plurality of storage bins 4, and each storage bin 4 is correspondingly provided with a screw conveyor 5; The material level device in the bin is used to control the stocking situation of the batching bin.

The screw conveyor 5 is provided with a variable frequency motor, which is connected to the screw blade shaft through a reducer; the speed of the variable frequency motor is controlled by a main control device such as a single-chip microcomputer or PLC through a frequency converter, and the speed of the screw blade shaft is positively related to the conveying capacity of the raw material. Relatedly, the delivery volume of the corresponding rotational speed in unit time is corresponding, that is, the main control device can control the rated supply volume of raw materials by controlling the rotational speed of the variable frequency motor in unit time, for example, if the base speed is v, where the raw material The ratio of A:B:C is 5:3:1, and the corresponding rotating speed of the screw conveyor 5 is 5v:3v:1v accordingly. In this way, the rapid raw material ratio is realized under the condition of satisfying the ratio accuracy.

Another optional solution is to set a rotation sensor for obtaining the number of revolutions on the motor or the reducer in the screw conveyor 5, wherein also, the motor is connected to the screw blade shaft through the reducer. At the same speed, the amount of raw material conveyed by the screw blade shaft is basically equal, and the number of rotations of the screw blade shaft can be obtained by measuring, so that the amount of raw material conveyed can be controlled more accurately.

As shown in Figure 1, at least one vibrating screen 1 is provided above the storage bin 4, and a magnet slag remover 2 is provided under the vibrating screen 1, and the magnet slag remover 2 provided is used to remove iron slag in the raw material. The underscreen of the sieve 1 is connected with each storage bin 4 through a rotary distributor 3 . Each storage bin 4 is fed by a rotary distributor 3 .

As shown in Fig. 1, in this example, there are two vibrating screens 1, and there are correspondingly two magnet cleaners 2 and rotary distributors 3, and each rotary distributor 3 is connected with each storage bin 4 respectively. part of the connection. Some storage bins 4 are connected with two rotary distributors 3 at the same time. With this structure, the storage capacity of each storage bin 4 can be adjusted conveniently. It is convenient to change the ratio of feed. For example, for raw materials with a large amount of consumption, two vibrating screens 1 can be used to feed materials at the same time, thereby increasing the feeding speed.

Each screw conveyor 5 is connected to a storage bucket 6, and a pneumatic gate 7 is arranged below the storage bucket 6. A batching scale for automatic weighing is arranged in the storage hopper 6 . The set batching scale can also be used as a verification monitor for automatic control of conveying accuracy. When abnormal conveying is found, it will be shut down for maintenance. For example, when the raw material transportation is relatively sufficient, switch to the separate transportation mode, that is, the storage bucket 6 at this time only accepts the feeding from one screw conveyor 5, and the screw conveyor is controlled by weighing the weight of the feeding material and the main control device 5, the raw material delivery volume of the screw conveyor 5 can be verified and monitored. The control difficulty of the utility model is not high, but the proportioning speed of raw materials is greatly improved, and the trouble-free running time of the whole system is improved, which has the value of popularization.
