Description

[Detailed Description of the Invention] The present invention relates to an improvement of the chute in an auger-set powder metering machine used for powders such as wasabi, mustard, and black pepper.

Conventionally, an auger-equipped powder metering machine has a chute (cover) 2 removably attached to the tip of a hopper 1, as shown in Fig. 1, and an auger 3 rotatably arranged inside the hopper 1 and chute 2. , and the inner wall surface 10 of chute 2
has a polished finish.

In this way, the inner wall surface 10 of the chute (cover) 2 of the auger 3 is polished and smoothed, so even if the auger 3 rotates when the auger 3 that sends out the powder sends out the powder in the hopper 1. , the powder slipped on the inner wall surface 10 of the chute 2, making it difficult to send out a constant amount of powder.

In other words, as shown in Fig. 1, if powder is placed on the screw 3a and the auger 3 is rotated once, since there is no resistance from the chute 2, the powder on the screw 3a will be transferred to the next screw 3.
It cannot move to the screw 3a and remains on the screw 3a.

Therefore, it was necessary to constantly operate various instruments and mechanical devices connected to the auger-equipped powder metering machine to ensure that a constant amount of powder was delivered.

In view of the current situation, the present invention provides a concave or convex portion on the inner wall surface of the chute to provide resistance to the flow of powder, so that the powder is always sent out in a constant amount as the auger rotates due to the resistance. The present invention was developed by slow-acting.

An embodiment of the present invention will be described below with reference to the drawings.

The auger set metering machine according to the present invention has a chute 2 removably attached to the tip of a hopper 1, like the conventional auger set metering machine shown in FIG. They are arranged freely.

However, the inner wall surface 10 of the chute 2 of the auger set quantitative meter according to the present invention has four parts or A convex portion is provided.

The concave portion or convex portion provided on the inner wall surface 10 of the chute 2 may be formed on the entire surface of the inner wall surface 10, only on the lower portion 10a, or on the lower portion 10.
Only a part of a, or only the upper part 10b, or the upper part 10
It may be present only in part of b, or only in part of lower part 10a and part of upper part 10b, and may be arbitrarily selected depending on the powder to be treated.

Further, the recesses or protrusions provided on the inner wall surface 10 of the chute 2 may be formed, for example, by forming grooves or scratches 11 in the axial direction (FIG. 2 or 3), or by forming grooves or scratches 11 in the axial direction so as to resist the rotation of the auger 3. Grooves or scratches 12 are formed at an angle to the surface (Fig. 4 or 5), grooves or scratches 13 are formed in a diamond-cut shape (
(Fig. 6), by attaching point-like protrusions or recesses 14 (Fig. 1), etc.

Note that the provision of recesses or protrusions is done to provide resistance to the flow of powder, so it is not limited to these, and the selection of the shape and structure depends on the type of powder. You can choose it arbitrarily.

In this example, the grooves or fills 12, 13 and the protrusions or recesses 14 have a depth or height of approximately 2 to 3 mm, and in FIG. 2, the pitch of the grooves or scratches 11 is approximately 5 mm. However, the size may be arbitrarily selected depending on the purpose.

Furthermore, in this embodiment, the chute 2 is of a trumpet type, but
The shape is not limited to this, and the shape can be arbitrarily selected.

As mentioned above, in the conventional auger-set powder metering machine, the inner wall surface 10 of the chute 2 is polished, so it does not have the power to feed the powder placed on the screw 3a in FIG.

In contrast, in the present invention, the inner wall surface 10 of the chute 2 is provided with a concave portion or a convex portion, so that the shape of the inner wall surface generates a force (resistance) that suppresses the powder on the screw 3a from rotating.

Therefore, when the auger 3 is rotated once in this state, the powder on the screw 3a can be moved onto the screw 3b.

In this way, by adding resistance to the chute 2, a conveying force can be generated in the chute 2.

In this way, the present invention provides resistance to the flow of powder by providing a concave or convex portion on the inner wall surface 10 of the chute 2, so that when the powder in the hopper 1 is sent out by the rotation of the auger 3, it is possible to Unlike a chute, the powder no longer slides on its smooth surface, and a constant amount of powder is sent out as the auger 3 rotates due to the resistance of the concave or convex portions.

Therefore, filling loss is extremely reduced, and the number of operations of attached equipment, etc., as required in the past, is reduced, and work efficiency is improved.
