FIG. 1 shows a threshing device equipped with an embodiment of the present invention. 1 is a threshing device such as a combine, and a handling room 2 is provided on the upper front side in the threshing device 1,
A handling cylinder 3 is axially mounted in the handling chamber 2. A handling barrel receiving net 3a is arranged below the handling barrel 3, and the handling barrel receiving net 3a is further provided.
The rocking shelf 4 is arranged below.

The structure of the swing shelf 4 will be described. 4b is a chaff sheave continuously provided at the rear end of the transfer shelf 4a, 4c is a gren sheave provided continuously to the end of the chaff sheave 4b, and 4d is a Straw rack set provided after the end of the glen sheave 4c. . A swing net is formed below the chaff sheave 4b and the Glen sheave 4c. Grains removed from the handling chamber 2 fall onto the transfer rack 4a and are transferred to the rear end side on the transfer rack 4a due to the rocking of the rocking rack 4 in the front-rear direction. Grains that have not fallen fall from the end portion of the handling barrel 3 of the handling chamber 2 onto the chaff sheave 4b, and join with the grain removal transferred from the transfer rack 4a. The combined objects to be treated are transferred from the chaff sheave 4b to the rear Glensieeve 4c while being wind-selected by the sorting wind from the Kara5. Straw pack 4d
It is discharged from the end of the machine to the outside of the machine. Further, the light dust that has not fallen on the transfer rack 4a or the chaff sheave 4b is discharged to the outside by the cross flow fan 12.

[0008] The rice that has been wind-selected and leaked is first taken into the helix 6 and then stored in a Glen tank or the like through a grain elevator or the like. Further, despite the wind selecting action, the residual object to be processed left on the chaff sheave 4b and the Glen sheave 4c is transferred to the Straw rack set 4d by the swing action.
During that time, the grain removal is loosened by the movement of the Straw rack plates 4e, 4f in the left-right direction with respect to the transport direction, and the residual processed material in which the branch stem particles are mixed leaks to the second spiral 7 to be processed. It is taken in as a thing.

The second object to be treated taken into the second spiral 7 is returned to the front part of the transfer rack 4a by the second object reducing device 14 and again subjected to the wind selecting action from the chaff sheave 4b to be selected. It should be noted that the second object to be treated may be reduced to the handling barrel 3 or a processing barrel or the like provided on one side of the handling barrel 3 to perform threshing treatment again. A U-shaped plate 9 for fitting and supporting the outer side surfaces of the base end portion of the Straw rack set 4d is used for supporting the above-mentioned Straw rack set 4d in the lateral direction with respect to the transport direction of the swinging rack 4.

This strengthens the rigidity of the tightening part and its vicinity,
Further, due to the displacement B in the longitudinal direction shown in FIG. 2, stress is not concentrated in one place on the Straw rack plates 4e and 4f, so cracks and damages are reduced.

Next, FIGS. 3 to 5 will be described. FIG.
[Fig. 6] is a view of the Straw rack plates 4e and 4f as viewed from the side. Conventionally, the end portions of the Straw rack plates 4e and 4f on the lower side in the transport direction are not completely overlapped with each other. As a result, due to the rocking of the rocking rack 4 in the front-rear direction, the Straw rack plates 4e and 4f also rock in the left-right direction, loosening grain removal and improving transport selection. However, as shown in FIG. 4, the Straw rack plates 4e and 4f vibrate in the left-right direction and sometimes crossed, which adversely affected the transportation of grain removal. In order to solve this, the configuration shown in FIG. 5 is adopted. That is, the step C is secured at the upper end of the stroll back plates 4e and 4f on the terminal side, and the overlap portion D is provided at the upper and lower intermediate portions on the terminal side. The Straw rack plates 4e and 4
