Description

[Detailed Description of the Invention] The present invention relates to a hopper that accommodates rice and sends it out from the bottom.

The hopper for storing rice has a cylindrical shape with a lower part inclined toward the center, and an on-off valve is provided at the lower end of the hopper.

Since the washed rice is directly thrown into the hopper, a bridging phenomenon occurs in which the rice gets clogged inside the hopper due to its own weight and cannot be dropped.

If this happens, you will need to poke the clogged part with a stick or the like to break it up.

However, after washing, rice becomes slightly soft due to water absorption, so if external force is applied to the rice, such as by poking it, the problem arises that the rice grains break.

This proposal solves the above problems.

A hopper for storing washed rice, the configuration of which is shown as an example in the drawings, will be described.

Reference numeral 1 denotes a lower hopper which is cylindrical in shape, has a circumferential wall inclined toward its center, and is arranged with its small diameter side at the bottom and its axis in the vertical direction, and a rice scale or other open/close valve 2 is attached to its lower end. .

The on-off valve 2 may be replaced with a shutter or the like, and the lower end opening of the lower hopper 1 may be opened and closed.

3 is a cylindrical upper hopper with a circumferential wall inclined toward the center, and is arranged in a stacked manner above the lower hopper 1 with the small diameter side facing downward and its battle line vertically; its lower end is connected to the lower hopper 1 The lower hopper 1 is inserted into the upper end of the lower hopper 1, and its axis is substantially aligned with the axis of the lower hopper 1.

There is no need to limit the configuration in which the lower end of the upper hopper 3 is inserted into the lower hopper 1, and it is also possible to position the lower end of the upper hopper 3 higher than the upper edge of the lower hopper 1. The upper edge of the lower hopper 1 and the lower edge of the upper hopper 3 may be connected by a plate to prevent the contents from spilling out from the upper edge.

That is, if the hoppers 1 and 3 are arranged with respect to each other so that the contents of the upper hopper 3 are fed into the lower hopper 1 and the contents of the lower hopper 1 do not come out from the upper part,
There is also no need to limit the alignment of their axes.

Reference numeral 4 denotes a tank disposed above the upper hopper 3, and a draining plate 5 such as a punched sheet or a net through which rice grains do not pass is provided at the upper part of the tank so as to be inclined so that the upper hopper 3 side is at the lower side.

A chute 6 is connected to the lower end of the draining plate 5 and feeds the rice on the draining plate 5 into the upper hopper 3. A chute 7 is located between the lower end of the draining plate 5 and the chute 6 and projects upward over its entire length. The provided baffle plate 8 is placed on the draining plate 5,
The rice scraper is mounted on a shaft close to the baffle plate 7 and is constructed by having plates protruding radially from the circumferential surface of a shaft provided parallel to the baffle plate 7.

The angle of inclination of the peripheral walls of the hoppers 1 and 3 is not limited as in the embodiment, and as long as the contents can be lowered, the entire length of the peripheral wall may be inclined, or only the lower part may be inclined. .

Further, even if the entire circumference of the hoppers 1 and 3 is inclined toward the center, only a part of the circumferential direction, for example, when the hopper is made into a rectangular cylinder, only two opposing walls are inclined.

To explain how rice is stored in and taken out from the hoppers 1 and 2 according to this embodiment, the washed rice is sent together with water to the upper end of the draining plate 5, and the water is transferred from the hole in the draining plate 5 to the tank 4. and let it flow down, leaving only the rice on the draining board 5.

The rice remaining on the draining plate 5 is moved to the baffle plate 7 according to the inclination of the draining plate 5, further drained here, and only the rice is scraped out into the chute 6 by a scraping tool 8 which is forcibly rotated.

The rice on the chute 6 passes through the upper hopper 3 to the lower hopper 1.
When the lower hopper 1 is full, it accumulates in the upper hopper 3.

These rice are taken out by opening the on-off valve 2 provided at the lower end of the lower hopper 1.

In this embodiment, a case is shown in which there is one upper hopper 3, but when the overall volume is large and the height thereof is high, a plurality of upper hoppers 3 are provided and they are sequentially arranged upward.

As shown in the above embodiment, the hopper of the present invention is divided into a plurality of hoppers each having a required volume, and these are arranged in a vertically stacked manner.

That is, in the communication portion between the upper and lower hoppers 1 and 3, the load of the contents of the upper hopper 3 acts on the contents of the lower hopper 1.

However, in the case where there are a plurality of lower hoppers 1 or upper hoppers 3, it is a part of the cross section of the lower hopper, and in the overlapping part of the peripheral wall of the other hoppers, each of the hoppers 1 and 3 The hoppers receive the load of their respective contents in a distributed manner, thereby reducing the load on the contents of each hopper.

Moreover, for the contents in the communicating portion of the upper and lower hoppers, the load of the upper contents acting on the lower contents is dispersed and absorbed by the surrounding areas with smaller loads.

Therefore, the entire weight of the upper part of the contents acts on the lower part of the contents, and this load can prevent rice from becoming stuck in the hopper.

In addition, the washed rice is supplied to the hoppers 1 and 3 by feeding the washed rice onto the inclined draining plate 5 and blocking the drained rice with the baffle plate 7, while passing it through the chute 6 with the scraping tool 8.
This is done by scraping out the liquid and feeding it into hoppers 1 and 3 in appropriate amounts.

Since the rice is dispersed and placed in hoppers 1 and 3, the potential energy of the rice at that time is reduced, and the clogging of rice due to this can be reduced, which more reliably prevents rice from clogging in the hoppers. It is possible to use the lower hopper 1
By opening the lower end with the on-off valve 2 or the like, the contents can be taken out smoothly at all times.

As mentioned above, in the proposed hopper, multiple hoppers are stacked vertically, and the load of the contents is divided and received by each hopper, so that the contents do not clog in the hopper due to the load. Since there is no need to apply any external force to the contents of the hopper, it can also be used to store items that may lose their shape, such as washed rice.
