DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment in which the present invention is applied to an apparatus for producing mixed feed for cattle will be described in detail with reference to the drawings. 2 and 3 show the overall configuration of the manufacturing apparatus according to the present embodiment, in which 10, 12, 14 are conveyors, and a plurality of types of blends fed at a predetermined ratio from an inlet 16. Raw materials are conveyed by these conveyors 10, 12, and 14 along a predetermined conveying path.

The various raw materials blended by these conveyors 10, 12, 14 are put into a preparation tank 18,
Further, after being mixed in the mixing tank 20, it is discharged through the hopper portion 21, and then the conveyors 22, 24, 26,
At 27, it is conveyed to a storage tank 28, where it is temporarily stored.

The mixed feed in the storage tank 28 is lifted by the conveyor 32 provided at the lower end of the hopper section 30 and the conveyors 33 and 34 continuous to the conveyor 32, and is then conveyed to the weighing bagging device 36. . Then, after being weighed by the weighing bag filling device 36 in a fixed amount, it is packed in a bag 80.

The preparation tank 18 and the mixing tank 20 are connected vertically as shown in FIG. A plurality of slit-shaped openings 38 are provided at the bottom of the preparation tank 18, and the openings 38 are opened and closed by the corresponding shutters 40.

These shutters 40 are connected to a first opening / closing cylinder 48 via a lever 44 and a rod 46 as shown in FIG.
Is rotated about the shaft 42 to open or close the opening 38.

The mixing tank 20 arranged below the preparation tank 18 is provided with a screw mixer 52 therein, and mixes various raw materials supplied by the rotation thereof.

The bottom of the mixing tank 20 is provided with a plurality of openings 54, which are opened and closed by a shutter 56. Here, the shutter 56 is connected to a second opening / closing cylinder 58 (see FIG. 2) via a rod 57 as shown in FIG. 4 (B), and by pushing and pulling the rod 57 by the operation of the cylinder 58, Figure 4
(B) The opening 54 is opened and closed by sliding in the left and right directions.

On the other hand, the weighing bagging device 36 has a cylindrical introduction part 60 as shown in FIG. 6, and the mixed feed conveyed by the conveyor 34 drops downward in the introduction part 60. It is designed to let you.

A pair of screws 62, 64, that is, a main screw 62 and a sub-screw 64, are rotatably arranged at the bottom of the cylindrical introducing portion 60. These screws 62 and 64 send the compounded feed that has dropped through the introduction section 60 to the drop port 66, and drop it from here to the hopper-shaped weighing device 68.

The hopper-shaped scale 68 is suspended by a frame 72 via a load cell 70 as shown in FIG. Further, a shutter 74 is provided at the opening at the lower end thereof, and the shutter 74 is opened and closed by a cylinder 78.

Next, the operation of the apparatus of this example will be described. In the apparatus of this example, various blended raw materials in a predetermined ratio, which have been charged into the mixing tank 20, are sufficiently mixed by rotating the mixer 52 inside for a certain period of time.

When the mixing for a predetermined time is completed, the shutter 56 is opened by the operation of the second opening / closing cylinder 58,
The mixed feed (mixed feed) inside the mixing tank 20 has an opening 54.
Can be dropped further down. The dropped mixed feed is dropped from the hopper section 21 to the conveyor 22, and the conveyor 2
It is sent to the storage tank 28 through 2, 24, 26 and 27 and is temporarily stored there.

While the various raw materials are being mixed in this mixing tank 20, the various raw materials are supplied to and stored in the preparation tank 18 thereabove, so that the various raw materials are mixed in the mixing tank 20. After the completion of the process, the next mixing raw material can be instantaneously charged from the preparation tank 18 to the mixing tank 20 at the stage of discharging it.

Therefore, the mixer 52 in the mixing tank 20
Can be followed by mixing of the raw materials. That is, in the apparatus of this example, it is possible to perform the mixing operation continuously despite the batchwise mixing of the raw materials, and there is almost no need for waiting time.

Now, the compounded feed which has been carried into the storage tank 28 and temporarily stored therein is carried by the conveyors 32, 33 and 34 to the weighing and bagging device 36, where it is weighed by a fixed amount and stored in the bag 80. Packed inside.

The series of operations will be described with reference to FIGS. 5 and 6. First, the mixed feed introduced through the introduction part 60 is sent to the left in FIG. 6 by the rotation of the pair of screws 62 and 64, and dropped to the hopper-shaped weighing device 68 from the downward drop port 66.

When a predetermined amount of, for example, 430 kg of compounded feed is put into the measuring device 68, the main screw 62 is automatically stopped at that stage, and only the sub-screw 64 is continuously rotated. . Then, when the remaining 20 kg is charged into the measuring device 68 by the sub-screw 64 (when measuring 450 kg in total),
The sub-screw 64 is also stopped, and the shutter 74 at the lower end of the weighing device 68 is opened by the cylinder 78, so that the mixed feed inside the weighing device 68 is dropped into the bag 80.

The main screw 62 and the sub-screw 64 are separately provided to feed the mixed feed for the following reason. That is, while the mixed feed is rapidly fed into the metering device 68 by the fast feed by the main screw 62, the weight of the compounded feed in the metering device 68 approaches a predetermined amount (about 430 kg).
By switching to feeding by the sub-screw 64 for fine adjustment, which is slow in feeding, it is possible to prevent the input amount to the measuring device 68 from becoming excessive or too small, and to correctly supply the measuring device 68 to the predetermined amount. (450 kg).

The embodiments of the present invention have been described in detail above, but this is merely an example, and the present invention can be applied to the production of, for example, chemical fertilizers and other solid compound products, and the spirit of the invention is not deviated. Within the scope, it can be configured in a form with various modifications based on the knowledge of those skilled in the art.
