Note that 14 is a sorting case that covers the rotary sorting cylinder 7.

At the rear of the aircraft, there is a pressure blower 15. A paddy return grain lifting machine 16 and a finished rice grain lifting machine 17 are provided.

When the pressure blower 15, paddy return grain lifting machine 16, and finished rice grain lifting machine 17 are arranged at the rear of the machine, the pressure blower 15 is arranged in the middle part, and the
A paddy-reducing grain-lifting machine 16 is installed on one side of the pressure-air blower 15, and a finished rice-lifting machine 17 is installed on the other side. The rotating portion of the rice frying machine 17 is configured to be driven by a single common drive shaft 18, and the impeller 15a of the pressure blower 15 is attached to the common drive shaft 18. A paddy transfer helix 19 and a paddy lifting blade 16a of a paddy return lifting machine 16 are attached to one side, and a finished rice transfer helix 20 and a finished rice lifting machine are attached to the other side of the common drive shaft 18. 17 finished rice frying blades 17a are attached. The front part of the pressure blower 15 is communicated with the rotary sorting tube 7 in the sorting case 14 through the mesh 21, and through the supply side end of the rotary sorting tube 7, the crushed rice is It is connected to the starting end of route 4.

Although one drawing is omitted, the shaft ends of the finished rice 9 and the mixed rice helix 11 are extended below the sliding rice wind selection path 4, and a pulley (not shown) is attached to the drive source (not shown in the drawing). Power is transmitted from the (omitted). Reference numeral 24 denotes an initial guide trough, and the upper end of the paddy guide 124 extends to the lower force for pumping up the elementary lifting cylinder 13 of the one-rotation sorting cylinder 7, and the first guide trough 2
The terminal end of 4 is communicated with a paddy return grain lifting machine 16 via a paddy transfer helix 19.

Next, the operation of the embodiment will be explained.

When carrying out hulling work, paddy is supplied to the paddy tank 2 of the hulling section 1, and each rotating part of the machine is driven. Then, the paddy supplied from the paddy tank 2 to the shedding rolls 3.3 is subjected to a shedding action, the rice that has fallen off is sorted by the wind-selecting channel 4 below, and the rice husks are removed from the suction fan chamber 5. , and is discharged to the outside of the machine via the dust exhaust pipe 6. The mixed rice of brown rice and paddy after wind selection is sent to Surorachimai wind selection route 4.
The grains flow down the flow board 4a and are supplied to the supply side end of the one-rotation sorting plate 7.

Next, the mixed rice supplied to the supply side end of the rotary sorting tube 7 is scooped up by the pot hole of the rotary sorting tube 7, which is rotating clockwise as shown in FIG. The mixed rice that has fallen into the finishing rice gutter 10 and mixed with paddy and some brown rice falls into the mixed rice 11112 and is sorted.
The unsorted mixed rice that has fallen into the mixed rice@12 is fed again from the conveyance end of the mixed rice gutter 12 to the supply side end of the rotary sorting cylinder 7 by the mixed rice helix 11, and is re-sorted.

In addition, the finished rice that has fallen into the finished rice 4i110 is transferred to the end side of the finished rice gutter 10 by the finished rice helix 9, and further passed through the finished rice transfer helix 20, and then taken out of the machine by the finished rice grain lifting machine 17. Ru. The sorted paddy sent to the discharge side end of the one-rotation sorting tube 7 enters the adjacent elementary lifting tube 13, is pumped up by the elementary lifting tube 13, and is passed through the initial guide trough 24 and the paddy transfer helix. 19, the paddy is returned to the paddy tank 2 of the shedding section 1 by the paddy return-lifting machine 16, and subjected to the lifting action again.

The hulling and sorting work is carried out as described above,
The rotation of the common drive shaft 18 causes the impeller 15 of the pressure blower 15 to
When a rotates, dust from the unhulled rice flowing down from the primary raising cylinder 13 through the initial guide trough 24 and dust from the paddy reduction frying machine 16 are sucked in from the side paddy transfer helix 19, and the dust from the paddy reduction frying machine 16 is sucked in. From the transfer helix 20, the finished rice grain lifting machine 1
The dust inside 7 is suctioned and cleaned, and the pressure blower 1
The pressure air flowing into the rotary sorting tube 7 from the rotary sorting tube 7
The dust inside the rotary sorting tube 7 flows to the side of the shedding section 1 and is guided to the scraped rice wind selection path 4, where it is passed through the paddy return grain lifting machine 16 and the finished rice grain lifting machine 17.
The dust generated in the rotary sorting tube 7 is collectively discharged from the dust exhaust tube 6 to the outside of the machine through the sloughed rice air passage.

In addition, when disposing the finished rice lifting machine 17, the paddy return lifting machine 16, and the pressure blower 15 at the rear of the machine, since they are rotationally driven by a common common drive shaft 18, their transmission configuration is significant. This makes it easier and more concise, and the whole can be made more compact.
