Description

[Detailed description of the invention] A first chamber containing a large-diameter chamber removal fan and a second chamber containing a small-diameter chamber removal fan are arranged at the bottom, and a first sorting chamber with a coarse sorting function is located in the middle. In addition, a second sorting room having a finish sorting function is arranged in the upper stage, and the first removing room and the first sorting room are connected by a first blow-up pipe, and the second removing room and the second sorting room are connected by a second blowing-up pipe. The first and second sorting chambers are connected to each other with a pipe, and the husk discharge ports provided on the sides of each of the first and second sorting chambers are connected to a fan for sucking and discharging rice husks through a suction cylinder, and the husks and unhusked are connected to the bottom of the first sorting chamber. The inventors of the present application have proposed a fully automatic removing device characterized in that a common outlet for mixed rice is opened, and this outlet faces the supply port for removed and undeflated mixed rice in a second removing room. This invention has already been developed and disclosed in Japanese Patent Application Laid-Open No. 15858/1983, but this invention is capable of removing and removing cells by providing a first evacuation chamber, a rough sorting chamber, a second evacuation chamber, and a finishing sorting chamber in succession. This method is designed to significantly enhance the sorting function, and although it is effective in increasing the removal and sorting functions, when this method is used, the rice grains that have been completely removed in the first removal process are mixed with the undeparted rice grains in the second removal process. Since the rice is removed from the chamber and subjected to unnecessary re-de-detaching at the same time as the unde-detachined rice, the rate at which this is crushed and becomes waste rice is extremely high, resulting in uneconomical effects.

The present invention is to sort out only the undehulled rice that has leaked out in the main de-fan storage case, ie, the first de-decompression, and send it to the auxiliary de-defan case, i.e., the second de-decompression case, to be re-defeated and re-sorted. The purpose of this is to eliminate the above-mentioned defects. In the illustrated embodiment, a main removal fan 2, an auxiliary removal fan 3, and a suction fan 4 are attached to a rotating shaft 1 installed on a machine frame, and these fans 2, 3, and 4 are placed in separate storage cases 2', 3' and 4', and above the main defan storage case 2' is provided a grain storage chamber 6 for removing rice via a blow-up pipe 5 that communicates with the case 2'. A rice husk suction pipe 7 that communicates with the suction fan storage case 4' is opened at the top, and a rice husk discharge pipe 8 is connected to the case 4', and a leakage rice sorting net is installed below the grain storage chamber 6. 9 is diagonally installed, and a suction pipe 10 is opened at the lower end of this leakage paddy sorting net 9 to the auxiliary defan storage case 3' for the leakage paddy, and the leakage paddy is transferred to the grain storage chamber 6. A secondary blow-up pipe 11 for re-blowing is provided in series, and a rice removal outlet 12 and a waste rice discharge port 13 are provided below the leakage-removal rice sorting net 9.

In the figure, 15 is a shell device, 16 is a suction chamber, and 17 is a
18 is a control valve, and 19 and 19' are linings.

That is, in the description, the main removal fan storage case 2'
The paddy is sucked into the case 2' through the intake hole provided at the center of the side of the case 2'. At the same time, the tip of each wing is affected by a low-pressure attack, and the removed rice is blown into the grain storage chamber 6 by the strong wind caused by the rotation of the wing, where the chaff is The rice husks are sucked into the suction fan case 4' through the suction pipe 7 opened above the suction chamber 6, and are then discharged to the outside through the discharge pipe 8. However, the de-rice and spilled rice are removed from the grain storage chamber 6. It gradually flows downward from the narrow drop opening at the bottom and falls onto the spilled paddy sorting net 9, and only the spilled paddy is guided to the end by this net 9 and reaches its lower end, and is assisted via the suction pipe 10. It enters the defan storage case 3' and undergoes the same defaning action as described above again in the case 3', and is again blown into the particle storage chamber 6 via the secondary blow-up pipe 11 by the auxiliary defan 3 in the case 3'. In rare cases, the rice is still sorted and guided by the above-mentioned sorting net, and the scraped rice that has fallen through the above-mentioned screen 9 reaches the draining outlet 12, and the waste rice is led to the discharge opening 13 and disposed of.

Since the present invention is as described above, it is fully automatic and can perform complete evacuation very efficiently.In particular, the present invention has a blow-up pipe on top of the main evacuation fan storage case that communicates with the case. A rice husk suction pipe is opened above the grain storage chamber to communicate with the suction fan storage case, and a rice husk discharge pipe is connected to the case. A leakage paddy sorting net is installed diagonally at the bottom of the chamber, and a suction pipe is opened at the lower end of this leakage paddy sorting net to the auxiliary defan storage case for the leakage paddy, and the leakage paddy is removed by the above-mentioned method. A secondary blow-up pipe that blows air into the grain storage chamber again is installed, and a rice removal outlet and waste rice discharge port are provided below the leakage rice sorting net, so that rice removal can be carried out in the auxiliary removal fan case. The rice that has not been removed remains in the main de-fan case, and it is possible to avoid the possibility that the de-decomposed rice will undergo unnecessary de-deactivation again in the same fan case and become broken rice. Therefore, there is an effect that the above-mentioned object of the present invention can be achieved reliably.
