The embodiment of the present invention is configured as described above, and its operation will be explained below.

First, when starting to use this vibration hopper (IJ), the sliding position of the pair of gate plates (9a) (9b) is adjusted according to the repose angle α of the container to be stored. That is, as shown in FIG. When material S1, for example, sand, is introduced into the vibrating hopper (1) via the large hopper α3 as shown in FIG.
The material box pressure receiver is received by the plate (6), and the receiver is received by the plate (6).
and the side wall portions (6a) (6h) (22a) (2
2b), the material S becomes stable at the bottom of the hopper (1) with its inherent angle of repose α.

The angle β formed by the material S is adjusted so that it is smaller than the angle of repose α of the material S and is equal to the angle β, and the nut θη is tightened at this sliding position to fix the material.

On the other hand, the first material pressure receiver passes through the entire opening (231) of the plate 04, and the material S flows into the second material surface pressure receiver between the plates as well, and is deposited thereon at an angle of repose α as described above.

Next, when the vibrator (G) is driven, a vibration force is generated in the direction of the arrow as shown in FIG. 1, and this is transmitted to the hopper body (2) via the spring QI. Then, Figures 5 and 6
As shown in the figure, the material S, which had been stable at an angle of repose α in a stationary state, is now promoted to a multi-flow flow due to the vibration yc of the hopper body (2), as shown in Figures 7 and 8. The material S is the second material pressure receiver at the valley edge (28a) (28b) of the plate 241.
X29a) (29h) flows downward, and the first material direct pressure receiver merges with the flow of material S flowing down through the openings (22a) and (22b) on both sides of the plate (2), and the material S flows downward through the gate plate (9a).

The first material pressure receiver has a large wasted space below the plate (2), which reduces the capacity of the vibrating hopper! It was enlarged to JIT's ゎ]. However, according to this embodiment,
By forming the inside of the opening and providing the plate c241 for the second material direct pressure receiver, most of the previously wasted space can be used effectively, and the material light JM filter can be increased for the same capacity. There is.

In addition, in the conventional vibrating hopper, the material existing on the central part of the plate was difficult to fluidize and had a long residence time, so there was a risk of deterioration. However, according to this embodiment, the fine particles flow out smoothly from this part, and the fear of deterioration due to long-term retention can be eliminated.

Further, according to this embodiment, compared to the conventional case, the material is inside the opening and the second material direct pressure receiver is at each edge (28a) (28) of the plate (to).
hX29a) (29b) Since it flows out to the discharge opening B below, the ability to discharge the material can be greatly improved.

Since the plate C4 of the second material direct pressure receiver in the housing has slopes (30a) (30b) that are inclined with respect to the vibration direction A, the material above this receives the same transfer action as that of a so-called vibrator.
In addition to improving the ability to extract materials, the amount of discharge can be controlled over a wide range by changing the vibration force of the vibrator.゛In addition, in the above embodiment, the vibration exciter (to) and the hopper body (to
) Since spring 4 is interposed between the hopper body (2)
It is also possible to drive the hopper body (2) resonantly, and in this case, the vibration width of the hopper body (2) can be greatly changed by changing the excitation frequency. In this case, in addition to the above-mentioned effects, the control range of the emission amount can be further widened.

It is assumed that it is supported so that it can vibrate by a spring (5).

In the hopper main body Gυ, the first material pressure receiver having an arcuate cross section has six plates fixed to both end wall members (33a) and (33b). The above-mentioned pair of bottom wall members (45a) (45b
) is formed with a discharge opening B extending from one end wall member (33a) to the other end wall member (33b), and a first material pressure receiver is provided above and parallel to this. The receiver is a plate (3a has openings on both sides (46a x 46
b) is formed and communicates with the above-mentioned discharge opening B.

The first material surface pressure receiver is a plate (b), and K is a pair of rectangular 1-no.
Four openings (35a) (351)) are formed, and a pair of second material 7N pressure receiving plates (40a) (40b) are arranged below these openings.

The first pressure receiver has an opening (35a) on the bottom surface of the plate (34).
Both short edges (36a) (36b) (37a) of (35b)
A pair of side wall members (37b) extending from one end wall member (33a) to the other end wall member (33b)

X41b). Such a member (41
a) (41b) (42a) (42b) Through f, the second material pressure receiver is fixed to the plate (40aX40b) and the first material direct pressure receiver is fixed to the plate (341).

The first 2nd material pressure receiver is plate (40a) (40h) Fl 1st
It has the same shape as the example, but both long edges have side wall members (
42a) (42b). - The second material direct pressure receiver is located between the short edge of one opening edge of the plate (40a) and the end wall (33a) of the hopper main body 6υ, and the same receiver is located between the other side of the plate (40a). The pressure receiver is between the short edge which is the opening edge and the other second material, and the pressure receiver is between the short edge which is the opening edge of the plate (40b), and the pressure receiver is the other opening edge of the plate (40b). Material discharge openings (47a) (47h×47c) are formed between the short edge portion and the end wall portion (33b), respectively. In addition, the receiving plate (40a) (401 is the vibration force A)

In the second material pressure receiver, the dimensions of the plates (40a) and (40b) and the vertical distance between them are determined.

Similarly, as shown in Figure 11, the first material pressure receiver is a plate (goods).
As shown in FIG. 13, the angle β1 formed by the line segment -L connecting both side edges of the opening B and the opposing side edges of the material discharge opening B with the horizontal line H-H is the repose angle α of the material to be stored. The dimensions of the plate (B) and the opening B of the first material pressure receiver, and the vertical distance between them are determined so that the size of the first material pressure receiver is smaller.

The second embodiment also operates in the same way as the first embodiment, but since the second material direct pressure receiver is closed on both long edge sides of the plate (40a x 4ob), the material is not discharged but on both short edges. The material is discharged from through the openings (47aX47bX47C).

When the material 8 is filled into the hopper body 0υ, the material is deposited as shown in FIGS. 12 and 13 and stabilized at an angle of repose α.

It is clear that this embodiment has the same effect as the first embodiment, but it has two openings (35a) and (35b) in the first material direct pressure receiver '4FiC34). The space one section below in the current direction is used more effectively. 1 fc side wall members (42a) (42b), reinforcing members (
41a) (41b) The second material pressure receiver is a plate (40a
Since the first material pressure receiver (X40b) is fixed to the plate (341), the strength is more stable than in the first embodiment. Therefore, a material with a higher specific gravity than in the first embodiment can be stored. It is also suitable for multiple openings (35a).
By forming (35b), the first embodiment can be said to be suitable for a large-sized vibrating hopper.

Next, a third embodiment of the present invention will be described with reference to FIGS. 16 to 19. In the figures, parts corresponding to those in FIGS. 5 to 8 of the first embodiment are designated by the same reference numerals.

That is, in this embodiment, the second material pressure receiver is the same as the first embodiment except for the entire structure of the plate (4) 9.

The second material direct pressure receiver of this embodiment is a completely flat plate with a different slope from the first embodiment. Edge (26a) (2
6b) (27aX27b) is the second material pressure receiver that faces the plate (27aX27b). The dimensions of the decoy and the distance between the top and bottom of these hoppers are determined.When such a hopper is filled with material, the material is stabilized in the state shown in Figures 16 and 17, and when the shaker is fully driven, the As shown in FIGS. 18 and 19, the second material surface pressure receiver is JIF'd to a conveyor (IQ) that flows down from each edge of the plate.

In this example, the second material has a plate plate (the ash catcher has no slope), so it is slightly inferior in discharge capacity and controllability compared to the above-mentioned example, but other effects are similarly inferior. .

Although each embodiment of the present invention has been described above, the present invention is of course not limited to these, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, a pair of vibrating electric motors (20a) (20b) were used as the vibrator, but a single vibrating electric motor may be used. Alternatively, an electric motor may be used to completely rotate the unbalanced weight by valving the pulley and belt.

The housing and electromagnet drive part may all be used.

Furthermore, in the first and third embodiments described above, a pair of gate plates (9a
) (9b) to determine the width of the discharge opening, that is, the width of the discharge opening, from both edges (12aX12b) of the plate (2) to the gate plate (9b).
a) The angle β between the straight line drawn by each of the opposing lines 1 in (9b) and the horizontal line is adjustable so that it can be applied to various materials, but the umbrella board is always made of materials with an angle of repose of 6 or more. In this case, the gate bodies (19a) (19b) can be omitted.

In addition, in the above embodiment, the vibrator (to) is attached to one end wall (7b) (33b) of the hopper body, and the first material direct pressure receiver in the hopper body vibrates in the extending direction of the plate. Although a force is applied, a vibration force may be applied in a direction perpendicular to this. In this case, the vibrator (to) is attached to one side wall of the hopper body, for example (3h) (32b), and the second material pressure receiver is placed at a fixed position between the plates (40a) (45b). In the illustrated case, the first material pressure bridge is fixed to the plate in a position rotated by 90 degrees in a horizontal plane. In this case, the inclined bottom wall (6a) (6b) (4
5a) (45b) are also inclined with respect to the direction of the vibration force, so that the controllability of material ejection is further improved. Other effects are similar to those of the above embodiment.

In the second embodiment described above, the second material pressure receiver is a plate (40a
Although the long edge side of the surface of X40h) was closed, the first material container pressure receiver may be fixed to the plate in the same manner as in the first embodiment, and all the material may be discharged from the long edge side of the surface as well. In this case, it is necessary to consider the angle of repose of the material in the same way as for both short edges.

Further, in the above embodiments, the opening formed in the plate of the first material direct pressure receiver has a rectangular shape, but is not limited to this, and may be circular, for example. In this case, the plate of the second material pressure receiver is also circular. Or it may be conical.

As described above, according to the vibrating hopper of the present invention, the space inside the hopper can be used more effectively than before, the size can be reduced for the same amount of storage, and the discharge capacity has also been improved further than before. It is possible to do something wrong. Furthermore, it is possible to reduce the area where the material tends to locally accumulate.
