Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain sorting and weighing device.

The present invention relates to a sorting and weighing mechanism that performs a rough sorting operation to remove large straw waste, wood chips, metal pieces, pebbles, etc. from received raw material grains, and then weighs the grains.
In particular, when the moisture content of the raw grain is outside the specified moisture content, the measurement is automatically stopped.

To explain with a diagram, 1 is the main frame, which is formed by combining angle steel.
A rough sorting device 2 is integrally mounted on the upper part of the main frame 1. 3 is a frame of the device 2.

The apparatus 2 has a structure as shown in the cross-sectional view of FIG. 2, and is composed of a symmetrical upper sorting body 4 and a lower sorting body 5. The sorting bodies 4 and 5 are slightly inclined so that the supply sides 6 and 7 on one side are high and the discharge sides 8 and 9 on the other side are low and slightly inclined. The sorting bodies 4, 5 are supported by vertical or inclined support rods 10, 11 so that their discharge sides 8, 9 can perform linear reciprocating motion P back and forth.
In the embodiment, the upper and lower ends of spring plates fixed at intermediate positions between the upper and lower discharge sides 8 and 9 are fixed to the frames of the discharge sides 8 and 9. Supply side 6, 7 of sorting bodies 4, 5
is mounted for horizontal circular motion. That is, a vertical shaft cylinder 12 is attached to a position near the middle of the supply sides 6 and 7, and an eccentric shaft 14,
15, and the upper and lower sorting bodies 4 and 5 are rotated horizontally by changing the phase by 180 degrees by eccentric shafts 14 and 15.

The sorting bodies 4 and 5 are connected to sorting nets 16 and 17, respectively.
It also has anti-clogging balls 18 and 19. 20 is a supply hopper, and 21 is a suction blower.

A storage tank 22 is provided at the upper end of the main frame 1 and below the rough sorting device 2 . The lower end outlet 23 of the storage tank 22 is provided with a switching valve 24 for large input and small input. The valve 24 is suspended from a shaft 25 attached to the discharge port 23, and when in a vertically hanging position, the valve 24 is suspended from the shaft 25 attached to the discharge port 23.
3 is closed, and the discharge port 23 is opened by rotating and moving approximately 45 degrees laterally. These rotations are performed by rotating the shaft 25, and the rotation of the shaft 25 is as follows.
This is done by a motor 26.

A small funnel 27 is formed in the center of the switching valve 24, a small valve 28 is attached to the small funnel 27, and a solenoid 29 for opening the small valve 28 is attached to the valve 24. 30 is a spring. That is, when the valve 24 moves as shown in FIG. 3 to open the discharge port 23, a large charge is made, but when the discharge port 23 is closed by the valve 24 and the small valve 28 is opened, a small charge is made. In the case of FIG. 3, a sample is also collected using a small funnel 27.

The sample opened from the small funnel 27 is transferred to the collection tube 31.
A test huller 32 is attached to the frame 1 so as to pass through the frame 1 to the test huller 32.
The rice hulled by the huller 32 is checked by a moisture meter 33.
moisture is measured. Storage tank 22
A metering tank 34 is provided at the bottom of the tank. The weighing tank 34 is placed on a platform scale 35,
At its lower end is an on-off valve 37 that is opened and closed by a motor 36.
is installed. The motor 36 is connected to the moisture meter 3.
3, and when the moisture content falls outside the specified range, the on-off valve 37 is automatically closed.

Since the present invention has the above configuration, when the raw material grain is allowed to flow down from the supply hopper 20, the raw material grain is
It is fed to the feed side 6 of the upper sorter 4. However,
The feed side 6 of the sorting body 4 is horizontally and circularly moved by the eccentric shaft 14, but the discharge side 8 makes a linear reciprocating motion P by the vertical or inclined support rod 10, so that the movement of the sorting net 16 is As shown in Fig. 6, from the supply side 6 to the center, the grain is moved in a direction to spread it over the board surface, and from the center to the discharge side 8, it is moved so that it can be sent out quickly, and then it is rational. Sort into.

In this sorting process, all long pieces of straw, wood chips, branches, metal pieces, etc. are removed, and extremely fine particles of sand are also removed.

The grains that have been roughly sorted flow into the storage tank 22. A switching valve 24 is attached to the discharge port 23 of the tank 22, and when the motor 26 is energized and the rotating shaft 25 is rotated, the valve 24 is fully opened and becomes the state shown in FIG. Grain is filled into the measuring tank 24 all at once. When the measurement is about to end, the motor 26 is energized to close the valve 24 and the solenoid 29 attached to the valve 24 is activated.
When energized, the small valve 28 is fully opened and the small funnel 27
is fully opened and the grains are dropped little by little from the small funnel 27 (Fig. 4), so that the weighing can be carried out quietly at the end of the weighing period.

When the measurement is completed, the motor 26 is energized again to fully open the valve 24 as shown in Fig. 3, but at this time, since there is still a small amount of grain in the small funnel 27, the solenoid 29 is turned on. When electricity is applied to open the closed small valve 28, the grain flows through the collection pipe 31 to the test huller 32 where it is hulled, and then flows into the moisture meter 33 where the moisture content is measured. be done. In this case, the moisture meter 33 and the motor 36 are connected in a relational manner, so if the moisture content is outside a certain value, the motor 36 is energized to fully close the on-off valve 37 and the grains in the measuring tank 34 are are to be taken out and returned without spilling.

The present invention has the above-mentioned structure and function, and in particular, there is a rough sorting device 2 at the top of the A-frame 1 for removing impurities from raw grains.

b. A storage tank 22 is provided at the bottom of the rough sorting device 2.

c. The discharge port 23 at the lower end of the storage tank 22 is provided with a switching valve 24 for large injection and small injection.

d. Forming a sample collection part in a part of the switching valve 24.

e Connect the test huller 32 and moisture meter 33 to the sample collection section.

f A measuring tank 34 is provided below the storage tank 22.

g. The moisture meter 33 and measuring tank 34 are connected to automatically stop measuring if the moisture content is outside the specified moisture content.

Since the above requirements are summarized, not only can rough selection and weighing be carried out rationally, but also grains with moisture content outside the specified moisture content can be returned.
