Fig. 3 is a rear view showing the recovery structure of rice bran. Fig. 4 is a plan view showing the structure for recovering the rice grain. Fig. 5 is a side view showing the recovery structure of rice bran. As shown in Figs. 3, 4 and 5, a discharge port 51 of the blowing mechanism 50 is formed above the discharged straw feed path 30. In the case where the threshing and discharging rice straw has fine grain rice, the fine grain rice can be recovered to the fluctuation sorting apparatus 41 by the wind by the blowing mechanism 50.

That is, the threshing and discharging rice straw moving on the discharged rice straw conveying path 30 is made to wind from above by the blowing mechanism 50, and the rice bran is blown away from the threshing and discharging rice straw by the wind. The rice dropped on the chute 55 descends from the chute 55 to the fan case 43b and slides on the fan case 43b to the front end of the fan case 43b Falls to the shaking motion separating apparatus 41.

Specifically, the blowing mechanism 50 is configured as shown in Figs. 3, 4, and 5.

The blowing mechanism 50 has an inlet 52 for introducing wind from the fan-fan unit 43 and an inlet 52 for connecting the outlet 52 to the outlet 51, And an air blowing passage 53 for supplying the air to the outside.

Thereby, the wind can be introduced into the lead-in section 52 from the lead-out fan device 43.

The introduction part 52 is biased toward the transverse part 43t with respect to the center 43c in the transverse direction of the threshing device 6 among the fan case 43b. The transverse section 43t is a transverse section on the side corresponding to the side where the base of the threshing and discharging rice straw which moves on the discharged rice straw conveying path 30 is located. In the shaking motion discriminating device 41, the sorting wind tends to flow more easily on the transverse side corresponding to the bottom side of the threshing and discharging rice straw than the transverse side corresponding to the end of the threshing and discharging straw. As a result, the wind can be introduced into the inlet portion 52 from the transverse portion side where more wind flows in the fan case 43b.

A partition plate positioned near the introduction port 52a may be installed on the inner surface side of the fan case 43b. In this case, the wind can be guided by the partition plate so as to easily flow into the inlet 52a, and the wind can be efficiently introduced into the inlet 52. [

More specifically, as shown in Figs. 3, 4 and 5, one end side of the threshing frame 60 is located at a lower portion (Not shown). More specifically, one end side of the threshing frame 60 and the rear wall portion of the downward portion 10a are connected. The other end side of the threshing frame 60 is connected to the upper portion 10b located above the upper side discharging rice straw transfer device 31 in the tread machine 10. Specifically, the other end side of the throne frame 60 is connected to the upper frame 10c constituting the upper portion 10b through the connecting member 62. [ The threshing frame 60 supports the upper portion 10b of the thruster 10 with the lower portion 10a of the thruster 10 as a reaction force member. Shaped frame portion 61 at one end side of the threshing frame 60 protrudes rearward from the rear end portion of the upper side of the thruster body 10. [ The threshing frame (60) bypasses the bottom side portion of the discharged rice straw transportation path (30) from the U-shaped frame portion (61).

The air passage 53 is provided with a fan side air passage 53a for connecting the inlet portion 52 to a portion of the U-shaped frame portion 61 located below the discharged straw conveying path 30, Side air passage 53b for connecting a portion located above the discharged straw pile conveying device 31 to the discharge port 51 and a portion to which the fan-side air passage 53a is connected in the U-shaped frame portion 61 And the portion where the discharge-side air passage 53b is connected. The portion between the fan side air passage 53a and the air outlet side air passage 53b in the air passage 53 is constituted by the U-shaped frame portion 61. [ The fan side air passage 53a and the discharge side air passage 53b are constituted by a pipe material.

The air introduced from the fan-fan unit 43 by the inlet unit 52 flows into the threshing frame 60 via the fan-side air passage 53a and flows into the discharge-side air passage 53b from the threshing frame 60, 51). That is, the blowing mechanism 50 uses the blowing fan unit 43 as a blowing source, introduces wind from the blowing fan unit 43 by the blowing unit 52, Is supplied to the discharge port (51) by the air passage (53) and is thrown from the discharge port (51) to the threshing discharge straw.
