Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rough sorting machine for grains.

(Prior art) In the conventionally known Japanese Patent Application Laid-open No. 54-97256, there are two upper and lower sorting nets in the upper swinging frame, two upper and lower sorting nets in the lower swinging frame, and the supply side is The high discharge side is installed at a low slope, and the entire system is equipped with a horizontal circular motion imparting mechanism.
It is described as being suspended from four hanging rods so that it moves in a circular motion with a 180 degree phase change.

In addition, in Japanese Utility Model Publication No. 48-37727, the sorting net is tilted high on the supply side and low on the discharge side, and a horizontal circular motion imparting mechanism is installed in the left and right center of the supply side, and the screen swings back and forth on the discharge side. A structure is described in which the lower part of the support rod is fixed to the discharge side, and the upper end of the support rod is fixed to the discharge side.

In addition, in Japanese Utility Model Publication No. 49-7190, a sorting net is provided with a high slope on the supply side and low on the discharge side, and a reversely sloped screening screen is provided at the bottom of the screen, and the supply side of the upper screening screen and the lower screening screen are provided. It is known that the discharge side of the upper sorting screen is formed to move in a linear reciprocating manner, and the discharge side of the upper sorting screen and the supply side of the lower sorting screen are made to move in a horizontal circle.

(Problem to be Solved by the Invention) However, the conventionally known device described in Japanese Patent Application Laid-Open No. 54-97256 has two upper and lower sorting nets in the upper swinging frame, and upper and lower screening screens in the lower swinging frame. The structure is complicated because there are two sorting nets, and since the movement is a horizontal circular motion, the distribution on the sorting net will not be uniform as the aircraft grows larger. However, there were some problems that required careful attention to detail.

Further, the device described in Japanese Utility Model Publication No. 48-37727 has only one swinging frame, so there is only one sorting net, and therefore rough selection is not possible.
Rough sorting refers to the process of removing straw, wood chips, and sand that are larger than the grain before processing.

Furthermore, in the device described in Japanese Utility Model Publication No. 49-7190, the supply side of the upper sorting net and the discharge side of the lower sorting net are formed to move back and forth in a straight line, so the lower sorting net is better. The upper sorting screen does not provide sufficient diffusion on the supply side. Furthermore, since the discharge side of the upper sorting screen and the supply side of the lower sorting screen are made to move horizontally in a circular motion, the lower sorting screen is better, but the discharge side of the upper sorting screen is unnecessarily diffused.

The on-off valve automatically closes when the moisture level falls outside the specified range.

(effect) Next, we will discuss the effect.

When raw grain is allowed to flow down from the supply hopper 20, it is supplied to the supply side 6 of the upper swing frame 4. The supply side 6 of the upper swing frame 4 is horizontally moved in a circular motion by an eccentric shaft 14 mounted on the left and right centers, while the discharge side 8 is supported by a spring plate support rod 10 supported on a horizontal shaft 38. 10, the movement of the sorting net 16 is controlled by the supply side 6 as shown in FIG.
The central part moves in a circular manner, but the left and right sides move smoothly, drawing slanted elliptical trajectories so as to push the grain to the left and right ends, respectively. Therefore, from the supply side 6 to the center in the moving direction, the grains are moved in a direction that spreads them over the board surface, and are quickly spread. And from the center of the moving direction to the discharge side 8
In the process, each part moves forward and backward in a long ellipse to quickly send it out, and then it is quickly and evenly distributed over the entire 16 sides of the rectangular sorting net, resulting in highly efficient sorting.

The sorting net 16 separates large pieces of straw, wood chips,
All tree branches, metal pieces, etc. are removed, as well as extremely fine particles of sand.

The grain from which the impurities have been removed by the sorting net 16 passes through the holes of the sorting net 16 and falls downward, and is supplied to the supply side of the sorting net 17 through the receiving trough 39. The eyes of the sorting net 17 are formed with small eyes that do not allow grains to pass through, but allow dirt to pass through, so that the grains are sieved by the sorting net 17 and taken out from the discharge side 9 thereof.

Since the sorting net 17 also moves in the same way as the sorting net 16, the sorting net 17 moves horizontally on the supply side and moves back and forth in a straight line on the discharge side 9 due to the eccentric shaft 15, so that the sorting can be done quickly. Ru.

The grains that have been roughly sorted flow into the storage tank 22. A switching valve 24 is attached to the lower end outlet 23 of the storage tank 22, and the motor 2
6 is energized to rotate the rotary shaft 25, the switching valve 24 is fully opened to the state shown in FIG. 3, and a large amount of grain is charged into the measuring tank 34 at once. At the end of metering interval, the motor 26 is energized to close the switching valve 24, and when the solenoid 29 attached to the switching valve 24 is energized, the small valve 2 is closed.
8 and fully open the small funnel 27.
Because the grains fall more gradually (Figure 4),
Weighing can be done quietly just before the end of weighing.

When the measurement is completed, the motor 26 is energized again and the switching valve 24 is fully opened as shown in Fig. 3.
At this time, there is a small amount of grain in the small funnel 27, so when the solenoid 29 is energized and the closed small valve 28 is opened, the grain will pass through the sampling pipe 31. Test huller 32
After that, the rice flows into the moisture meter 33 and its moisture content is measured.

In this case, the moisture meter 33 and the motor 36 are connected in a related manner, so if the moisture content is outside a certain value, the motor 36 is energized and the on-off valve 37 is fully opened, so that no grains are in the measuring tank 34. It can be taken out and returned without spilling.

(Effect) As mentioned above, the conventionally known Japanese Patent Application Laid-open No. 54-97256
In the publication, two screening screens (upper and lower) are installed in the upper swinging frame, and two screening screens (upper and lower) are also installed in the lower swinging frame, with the supply side being high and the discharge side being sloped low, so that the entire structure is horizontal. There is a description of a device that is suspended from four hanging rods so that it can move in a circular motion with a 180-degree phase change using a circular motion imparting mechanism. In addition, in Japanese Utility Model Publication No. 48-37727, the sorting net is tilted high on the supply side and low on the discharge side, and a horizontal circular motion imparting mechanism is installed in the left and right center of the supply side, and the screen swings back and forth on the discharge side. A structure is described in which the lower part of the support rod is fixed to the discharge side, and the upper end of the support rod is fixed to the discharge side. Also, Jitsukō 49-7190
In the publication, a sorting net is provided with a high slope on the supply side and low on the discharge side, and a reversely inclined screening screen is provided at the bottom of the screen, and the feed side of the upper screening screen and the discharge side of the lower screening screen are moved in a linear reciprocating manner. It is known that the discharge side of the upper sorting screen and the supply side of the lower sorting screen move horizontally in a circular motion.

However, the conventionally known device described in JP-A No. 54-97256 has two upper and lower sorting nets in the upper swinging frame, and two upper and lower screening screens in the lower swinging frame. Since the structure is complex and the motion is a horizontal circular motion, the distribution on the sorting network will not be uniform as the aircraft grows larger, so this is a problem that requires careful consideration when implementing it. The dot was hot.
Further, the device described in Japanese Utility Model Publication No. 48-37727 has only one swinging frame, so there is only one sorting net, and therefore rough selection is not possible. Rough sorting refers to the process of removing straw, wood chips, and sand that are larger than the grain before processing. Also, Jikko 49-
In the device described in Publication No. 7190, the supply side of the upper sorting net and the discharge side of the lower sorting net are formed to move back and forth in a straight line, so the lower sorting net is better, but the upper sorting net is better. , supply-side diffusion is not sufficient. Furthermore, since the discharge side of the upper sorting screen and the supply side of the lower sorting screen are made to move horizontally in a circular motion, the lower sorting screen is better, but the discharge side of the upper sorting screen is unnecessarily diffused.

However, in the present invention, only one sorting net 16 is provided in the upper swing frame 4, which is formed with meshes that allow grain to pass through but not straw waste.
Since it is installed at a low slope, the sorting net 16 in the upper swinging frame 4 can separate the two, allowing the grain to pass through but not the straw waste, and only one sorting net 16 can perform this function. Therefore, the structure is simple, and since a lower screen 41 parallel to the lower surface of the sorting net 16 is provided at intervals and a clogging prevention ball 18 is provided within the interval, clogging of the sorting net 16 can be prevented. , a lower swinging frame 5 is provided below the lower swinging frame 5, and only one sorting net 17 is formed in the lower swinging frame 5 with meshes that allow the passage of earth and sand but not grains. Since the side 9 is provided with a low slope, it is possible to separate soil and grain with only one screening screen 17, and lower screens 42 parallel to this screening screen 17 are provided at intervals on the lower surface of the screening screen 17. Since the anti-clogging ball 19 is provided, clogging of the sorting net 17 can be prevented, and the upper swing frame 4 and the lower swing frame 5 are arranged so that the supply side 6 and the supply side 7 and the discharge side 8 and the discharge side 9 are on the same side. Since they are arranged in parallel, it is possible to easily install the same device on the upper and lower supply sides 6, 7 and discharge sides 8, 9. Since the guide gutter 39 is provided to guide the grains that have passed through the lower screen 41 to the supply side 7 of the lower swing frame 5, the grains can be guided to the oppositely located supply side 7. Since the horizontal circular motion imparting mechanism is installed at the center position with a phase difference of 180 degrees, the supply side 6 and the supply side 7 can be swung to spread the grain, and the horizontal circular motion imparting mechanism can be attached to the upper and lower intermediate positions of the discharge side 8 and the discharge side 9. A shaft 38 is provided, and the lower ends of the upper support rods 10, 10 made of spring plates and the upper ends of the lower support rods 11, 11 made of spring plates are attached to the horizontal axis 38 in a shape that bends in the front-rear direction. Since the discharge side 8 of the upper swing frame 4 is fixed to the upper end of the upper swing frame 10, 10, and the discharge side 9 of the lower swing frame 5 is fixed to the lower end of the lower support rod 11, 11 made of spring plate, the discharge Both the side 8 and the discharge side 9 can be linearly swung in a direction that improves discharge, and since a straw takeout gutter 43 is formed on the discharge side 8 and a grain takeout gutter 44 is formed on the discharge side 9, grains and straw waste can be separated. Sediment can be separated and it has the effect of being a rough separator.
