Description

[Detailed description of the invention] The present invention relates to improvements in grain sorting equipment.

In order to sort out impurities such as dust, foreign particles, floating pieces, and crushed grains mixed in the grains by specific gravity, the grains containing the impurities are fed to the sorting 5A@ equipped with a sorting air passage, and the grains are sorted. While flowing down the air path, air is sent from the VL75 direction to sort the grains, and the grains with molds are sent to the discharge section near the beginning of the path, and the grains that are light and grainy are sorted. A device such as that disclosed in Japanese Patent Publication No. 51-1 '29757, which collects and discharges the air at a discharge section at the end of the air passage, is known.

The present invention provides an apparatus t equipped with the above-mentioned sorting air passage, which is provided with an air sorting chamber in which grain flow passages and insects δ are arranged in tandem on the starting end side of the sorting air passage. In addition, by providing a separation chamber with an inclined separation plate at the end of the sorting air path, a high-efficiency m
The wind-selecting action of ground grains and the efficient wind speed action of separated impurities are carried out, thereby improving the quality of the sorted grains and the useful impurities. The aim is to provide high-performance equipment.

The present invention will be explained with reference to embodiment figures. Reference numeral 1 is a box-shaped C frame, and a vibrating conveying gutter 3 with a supply tank 2 mounted on the upper side of the machine frame 1, and an air exhaust pipe 4 connected to an air exhaust fan (not shown) on the other side. The discharge side of the vibrating conveying gutter 3 is connected to a wind selection chamber 6 provided at the starting end side of the selection air passage 5 housed inside the machine frame 1, and the wind selection chamber 6 A picture window 7 is provided on the front wall thereof, a grain discharge channel 9 is connected to an outlet 8 provided at the bottom thereof, and the terminal side of the sorting air channel 5 is enlarged to form a -C separation line 10; A ventilation window 13 and a discharge conveyor 14 are installed on the earthen wall of the separated seedlings 10.A ventilation opening 11 is connected to the ventilation pipe 4, and a ventilation window 13 and a discharge conveyor 14 are provided at the lower end of one side inclined wall 12 provided at the bottom thereof. Inclined outflow channel 15 with
The bottom wall 16 of the inclined outflow channel 15 or its extension is connected to the wall surface of the temporal inclined wall 12 at an appropriate interval 17.
The inclined separation plates 18 and 19 are installed in parallel through the 20
is the vibration device of the vibrating conveyance gutter 3, 21 is the flow path guide plate in the sorting air passage 5, and 22 is the passage J! @Opening/closing valve for window 13, 23 is air volume regulating plate, 24 is supply port of supply tank 2, 25 is downstream passage, 3
1 is a frame body with a built-in supply tank 2; 33 is an elastic spring 32;
It is a locking rod. The interior of the Kanki-style Senpo 6 has a side wall plate 27 with a tilting plate 26 in the center, and the grains flowing down from above flow down a grain flow channel 28 with a tilting plate 26. Wind sorting is carried out by the wind flowing in from the picture style window 7, and the wind flowing in from the lower part of the grain size discharge passage 9 passes through the ventilation passage 29 side and is sent to the sorting air passage 5.
It is formed upstream of C.

With the above configuration, the grains (for example, brown rice) put into the supply tank 2 flow into the vibrating conveyance gutter 3, flow through the C gutter due to the vibration action of the vibration technique FF120, and flow down from the gutter end. It flows down into the passage 25 and flows into the J-plate sorter 6 provided at the beginning end of the sorting air passage 5. In the wind sorting chamber 6, while the brown rice flows down the grain flow path 28 in a zigzag pattern, the suction force of the exhaust J1 machine (not shown) connected to the wind exhaust pipe 4 causes Fresh air from outside the machine flows in through the picture window 7 and is air-sorted, and the heavy grains of brown rice, etc. flow down to the lower grain discharge channel 9 due to their own weight and are discharged outside the machine Ii7.
Light and small immature grains, crushed grains, dust, and other contaminants mixed in the brown rice float to the surface by the sorting air, flow out to the upper end side of the ventilation passage 29, and flow upward through the ventilation passage 29 from the lower part D). The strong wind definitely pushes up the contaminants and flows into the separation section 10 along with the violent wind inside the sorting room 1 route 5. For the corresponding part ^i "0, the installed inclined separator plate'I 8
The dust-containing wind comes into contact with the impurities, and the impurities that are useful, such as small unripe particles and crushed particles, are separated from the shoulder by themselves and flow through the inclined separator plate 18, and the downward inclined separator plate 19.
A portion of the wind flowing in from the blood window 13 through the gap 17 passes through the inclined outflow channel 15; the dust is separated from the foreign matter, and the dust floats to the surface. Only the re-sorted contaminants flow down to the bottom of the inclined outflow path 15 and accumulate at the discharge conveyor 1.
4 to be taken out of the machine. In addition, dust-containing air such as dust and dirt is discharged from the exhaust port 11 in the upper wall section upstream on the surface of the inclined separation plate 18 to the outside of the machine via the exhaust pipe 4.

Claim No. (S) (Based on the supply tank 2 opening the C discharge valve 34 by vertical movement of the tank 2)!'
1 is formed in a suspended tank device to be closed, and when the grains m to be fed into the supply tank 2 enter jf9, the lever 30 suspending the tank 2 loosens the elastic spring 32 and descends. At the same time, the discharge valve 34 connected to the operating link 35 gradually opens, and when the amount of grains in the supply tank 2 decreases, the tank 2 rises and the discharge valve 34 gradually closes. Even if the amount of grains fed into the supply tank 2 changes intermittently, the amount of grains stored in the grain tank is always maintained at an appropriate level, and the amount of grain discharged is appropriately regulated to maintain the wind selection effect of the sorting air channel. It has the effect of maintaining the system well and smoothly.

As described above, the grain sorting device of the present invention can efficiently perform wind sorting of heavy grains in the wind sorting chamber provided at the beginning end of the sorting air passage, and can also separate and remove impurities. For the purpose of wind sorting, a sorting cloth is installed at the end of the road.Since this is carried out with separated seedlings, it is possible to reliably improve the quality of the sorted grains and the useful impurities.
