Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a hopper device that prevents a stored material from being clogged or an abnormal discharge state in the vicinity of a discharge port in a hopper body.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a hopper device has been widely put into practical use in order to store stored items such as stick tea and to discharge the stored items in a fixed amount.

In such a hopper device, a stored item introduced into the inside of the opening of the hopper body is dropped by its own weight, discharged from the discharge port, and supplied.

[0004]

[Problems to be solved by the device]

 However, in such a conventional hopper device, if the above-mentioned stored material is partially hardened due to non-uniform moisture and the particle size is unevenly distributed, the stored material near the tapered discharge port in the hopper main body There was a problem that the flow became unstable and the fall became unstable, and it gradually accumulated on a part and a bridge phenomenon occurred.

Further, such a bridge phenomenon is gradually promoted to make it impossible to quantitatively discharge the stored material, and the discharging operation itself is completely stopped, which causes a stagnation of the entire processing operation of the stored material, which is not preferable. there were.

The present invention solves the above-mentioned conventional problems, and positively reduces and eliminates the occurrence of the bridge phenomenon in the hopper body to reduce the compressive force of the deposit, and thereby the stored material It is an object of the present invention to provide a hopper device capable of stably and smoothly discharging a constant amount of the hopper main body.

[0007]

A hopper device according to the invention of claim 1 is one in which ridge-shaped bridge-preventing rocking members are horizontally supported so as to be rockable on mutually opposing wall surfaces in a hopper body. Is.

In the hopper device according to the second aspect of the present invention, the bridge preventing swing member is mounted on a mountain-shaped swing bracket that is swingably supported by the wall surfaces of the hopper body that face each other. Is.

In the hopper device according to the invention of claim 3, a manual or automatic driving means is connected to the bridge preventing swing member so that the bridge preventing swing member can be forcibly swung. .

[0010]

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway front view of a hopper device according to the present invention, and FIG. 2 is a longitudinal sectional view of the same.

In FIG. 1, reference numeral 1 denotes a hopper body, the upper half of which is a rectangular tubular portion 1a, and the lower half of which is a chute-shaped portion 1b whose lower end is tapered. The shape of the hopper body 1 is an example and is not particularly limited. For example, it may be cylindrical. The hopper main body 1 has an opening at the upper end to serve as a charging port 2 and a lower end to serve as a discharging port 3. The stored material charged from the charging port 2 drops into the chute-like portion 1b and is discharged. It is designed to be discharged from the outlet 3.

Further, a mountain-shaped bridge preventing swing member 4 is installed above the discharge port 3 in the hopper body 1 so as to be swingably horizontally supported by wall surfaces facing each other.

In this embodiment, the bridge prevention rocking member 4 is attached to the upper and lower parts so that the upper part and the lower part do not overlap each other in the vertical direction. It is provided at regular intervals.

As shown in FIG. 3, the bridge preventing swinging member 4 has a total length slightly smaller than the distance between the facing inner wall surfaces, a chevron portion makes an angle of, for example, 70 °, and both end edges thereof have a hopper body. The inclined portion 4a is formed along the inclination of the first wall surface.

Reference numeral 5 is a chevron-shaped rocking bracket attached to each of the opposite wall surfaces of the hopper body 1. As shown in detail in FIGS. 4 and 5, the inclined portion at one end is covered by the closing plate 6. It is composed of a mountain-shaped member having a closed structure.

A horizontally elongated substantially elliptical hole 7 is formed in the central portion of the cover plate 6, and the shaft support member 8 passing through the elliptical hole 7 is airtightly fixed to each of the wall surfaces, thereby The chevron bracket 5 can be swung about the pivot member 8.

Then, the bridge preventing swinging member 4 as shown in FIG. 3 is placed on the pair of chevron-shaped rocking brackets 5 pivotally supported on the facing wall surfaces so that the chevron parts are aligned. The bridge preventing swing member 4 and the chevron swing bracket 5 can swing about the shaft support member 8.

Next, the operation will be described. In the hopper device having the above-mentioned configuration, a stored item such as a stick tea is put in from the upper input port 2 of the hopper main body 1, and this is dropped to the upper half of the rectangular tubular portion 1a and the chute portion 1b to be discharged. From the outlet 3, for example, it is discharged onto a belt conveyor 9 arranged in the lower part of the hopper body 1.

In this case, during the fall of the stored material into the discharge port 3 of the hopper body 1, a mountain-shaped bridge preventing swinging member 4 swingable around the shaft supporting member 8 is vertically extended. Since it is provided, the bridge-preventing rocking member 4 swings so as to make a pendulum motion when receiving the falling gravity of the stored goods, and the occurrence of a bridge due to the entanglement of the stored goods in the hopper body 1 is caused. In addition to preventing it, the generated bridge can be slid down smoothly.

That is, the stored matter accumulated on the ridge of the mountain shape smoothly slides down while reducing the compressive force of the sediment due to the change in the action direction of gravity, or it freely falls due to the above pendulum motion to reduce the compressive force of the compressive force. Disperses the direction of action and effectively suppresses the occurrence of the bridge phenomenon.

The angle forming the isosceles, which is the ridgeline of the mountain shape, does not necessarily fall within the angle of repose of the stored object, but within 2 times the angle of repose when the pendulum movement is not performed as described above. Is desirable.

Further, the pendulum motion can be forcibly given by using an external prime mover (not shown) or manually, but in this embodiment, the falling gravity of the stored object Or spontaneously generated by microvibration generated during operation.

[Effect of device]

 As described above, according to the first aspect of the invention, since the mountain-shaped bridge-preventing rocking members are horizontally supported so as to be rockable on the mutually opposing wall surfaces in the hopper body, the bridge in the hopper body is constructed. It is possible to positively reduce and eliminate the occurrence of the phenomenon and reduce the compressive force of the accumulation, which has the effect of being able to stably and smoothly discharge a fixed amount of the stored products from the hopper body.

Further, according to the invention of claim 2, the bridge preventing swing member is mounted on the chevron swing bracket which is swingably supported by the wall surfaces facing each other in the hopper body. Therefore, simply prepare an anti-bridge rocking bracket with a length corresponding to the distance between the opposite wall surfaces, and place it on the chevron bracket to mount the anti-bridge rocking bracket on the hopper body. However, regardless of the size or shape of the hopper body, there is an effect that a hopper can be easily and quickly implemented.
