Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a divider for dividing granular materials such as grains into specified division ratios.

BACKGROUND TECHNOLOGY Conventionally, in order to divide substantially uniform granular materials such as grains into specified division ratios, it has been common to use a balance or platform scale to measure the weight.

Problems to be solved by the invention The conventional method using a balance or table scale requires two steps: first transferring the granular material to be divided into a balance plate, checking its amount, and then storing it in a predetermined container, etc. Not only is it time-consuming, but it is also very troublesome to weigh it using a scale or the like.

Means for Solving the Problems In order to solve the above problems, in this invention,
For example, by simply putting the granules to be divided into the upper hopper 1, the two lower discharge pipes 21a and 21b
A conical diffusion plate 6 is disposed below the hopper 1 and has an apex 7 located directly below the outlet 2 of the hopper 1 so that the granules to be divided which have been divided into accurate division ratios are discharged separately. On the outer periphery of the diffusion plate 6, a large number of granules are erected parallel to the moving direction of the granular material to be divided, which falls from the outlet 2 of the hopper 1 to the top 7 and slides down while being spread evenly on the diffusion plate 6. The partition plates 8... are provided with a spacing ratio corresponding to the specified division ratio, and two types of partitions formed by being partitioned by the partition plates 8... and arranged alternately are provided. The first inlet and the second inlet 10...
are connected to each one of two different passages connected to the outside.

Function When a certain amount of granular materials such as grains put into the hopper 1 are discharged from the outlet 2 of the hopper 1 to the top 7 of the conical diffusion plate 6 located below, it is diffused from the top 7. It slides down onto the diffusion plate 6 while being spread evenly over the entire surface of the plate 6. The granules are then divided into a large number of two types of inlets arranged alternately at the outer periphery of the diffusion plate 6, divided at a predetermined division ratio, and sent through separate passages to an external source. They are each guided and housed in a container (not shown).

Embodiments Hereinafter, preferred embodiments of the present invention will be described based on the accompanying drawings. Note that in this embodiment, the dividing ratio of the granules is 1:1.

FIG. 1 of the accompanying drawings is a longitudinal sectional front view, FIG. 2 is a cross-sectional view taken along the - line in FIG. 1, and FIG. 3 is a partially cutaway side view.

As shown in FIGS. 1 and 3, the reference numeral 1 is
This is a funnel-shaped hopper that stores grains such as rice, soybeans, and adzuki beans, and has an outlet 2 for the grains at the bottom center. The outlet 2 is provided with an outlet pipe 4 equipped with a stopper 3 that can arbitrarily stop the grain from flowing down, and an umbrella part 5 attached to the lower part of the outlet pipe 4 to prevent the grain from scattering. Note that, as shown in FIGS. 1 and 3, the hopper 1 has connecting rods 15, 15, 15 whose tips are fixed to the outer surface of the inclined portion thereof,

In FIGS. 1 to 3, reference numeral 6 denotes a plurality of partition walls 12 hanging from the upper conical portion and the outer peripheral edge of the lower end of the conical shape at equal intervals, respectively.
and a diffuser plate integrally formed with the top part 7 of the conical part located directly below the outlet 2 of the hopper 1, and with an appropriate distance between it and the inner wall of the umbrella part 5. It is arranged so that it stands up. This diffuser plate 6
has an outer plate 9 on the outside of a pair of partition plates 8, 8..., which stand upright parallel to the direction of falling grain that slides down thereon, and each has an open inner side. It is fixed to a boat-shaped guiding member. The specific structure of the fixed state of the guide member and the diffusion plate 6 is such that the open portions inside the guide member match the gaps between the partition walls 12... The longitudinal edges of the guide member are fixed to the side edges of each partition plate 8 of the guide member. Further, each of the guide members is supported by the cover body 14 by fixing the outer surfaces of the outer plates 9 to the inner surface of the cover body 14.

A is attached. Of these, Hopper 11
The inner side, the discharge port 20a, and the discharge pipe 21a form a first passage communicating with the first inlet.

As shown in FIGS. 1 and 3, an outer hopper 17 having a size and shape that can surround the inner hopper 11 is provided at the lower edge of the cover body 14 with a gap through which the grains can pass. The upper edge is fixed. In addition, the outlet 20b at the lower end of the outer hopper 17
A discharge pipe 21b communicating with the outside is attached to the discharge pipe 21b, and the discharge pipe 21a and the discharge pipe 21b are connected to each other.
They are arranged on concentric circles, and their exits are located at different positions. In addition, between the inner hopper 11 and the outer hopper 17 and the discharge port 20
b and the discharge pipe 21b serve as a second passage communicating with the gaps 13.

Next, the operation of the above embodiment will be explained.

When grains such as rice, soybeans, adzuki beans, etc. are stored in the hopper 1 and the stopper 3 is rotated to open the outlet 2 of the hopper 1, the grains fall through the outlet pipe 4 and pass through the conical diffusion plate. It corresponds to the top 7 of 6. Then, the grains slide down from the top 7 while spreading over the entire surface of the diffusion plate 6 and reach the outer periphery of the diffusion plate 6. One of the grains flows into the boat-shaped guide member from each first inlet, and the other one flows into each of the first inlets. 2 Inlet 10... to gap 13...
...divide and flow into each other in equal proportions. Subsequently, the grains guided into the guide member pass through the inner hopper 11, which is the first passage, and enter an appropriate external container (not shown) from the discharge pipe 21a, while passing through the gap 13.
...The grains that have entered are placed in hopper 1 in the second passage.
1 and the outer hopper 17, and enters from the discharge pipe 21b into an appropriate container (not shown) different from the container on the discharge pipe 21a side. It should be noted that when the grains flow separately into the first inlet and the second inlet 10, which are separated by the partition plates 8 and arranged adjacent to each other as described above, even if only partially. Even if there is a slight difference in the amount of inflow into the two inlets, the opposite difference may occur in other parts, and the difference will be canceled out as a whole, resulting in grain growth. The divided flow rates are approximately equal when passing through each passage. Experiments have shown that the accuracy of this division is equal to or higher than when using various conventional scales.

By the way, the present invention is not limited to the above-mentioned embodiments. For example, each of the first inlets and each of the second inlets
Set the interval width of the inlet 10 to another ratio,
By setting the interval width of the partition plates 8..., the division ratio of grains to be divided can be easily changed. Also, the first
The structure of the inlet and the second inlet gap 10 may be any other structure as long as a large number of partition plates 8 are provided between the two members. Furthermore, the object to be divided may be not only grains but also small mechanical parts such as bolts and nuts, and various granular raw materials as long as they are granular. In such a case, it is necessary to adjust the interval width between the first inlet and the second inlet in accordance with the inflow state of the target particulate matter.

Effects As described above, in this invention, a conical diffusion plate is arranged so that the top of the plate is located at the outlet where the particulate matter contained in the hopper disposed above flows downward from the hopper. Moreover, on the outer periphery of the diffusion plate, a number of partition plates are erected in parallel with the moving direction of the particulate matter that slides down while being diffused on the diffusion plate. 2
Each type of inlet is connected to two different downward passages, so when dividing granular materials, it is possible to instantly divide the granular materials by simply pouring the granular materials into the hopper. This has the effect of being able to divide granular materials with a relatively high degree of precision.
