  In a harvesting operation in a small field, a combine with a light weight structure that can make the entire body compact while securing the cutting width of the cereals is desired. In the conventional technology, when the handling cylinder is arranged in the left-right direction of the traveling machine body, the front-rear width of the threshing portion can be reduced compared to the structure in which the handling cylinder is arranged in the front-rear direction of the traveling machine body. There are structural problems such as the engine or the threshing unit being arranged side by side, the drive structure of each part of the combine being complicated, and the miniaturization of the entire combine not being easily considered. In addition, in the structure where a rocking sorter is placed below the handling cylinder, and the cereals falling from the handling cylinder are sorted by the rocking sorter and the grain is taken out, the amount of waste in the extracted grain is Although it can be reduced, the removal operation of the swing sorter is troublesome, and handling problems such as the swing sorter cannot be easily extracted during the harvesting operation are likely to occur.

  Therefore, the present invention seeks to provide a general combine that has been improved by examining these current conditions.

  In order to achieve the object, a combine of an invention according to claim 1 includes a cutting unit having a cutting blade, a threshing unit having a handling cylinder and a swing sorter, a traveling unit having a traveling unit and an engine, In a combine that supplies cereal grains from a reaping part to the threshing part, a swing sorter is disposed below the handling drum, and the swing sorter is pivoted in the left-right direction of the traveling machine body, and the handling drum This is a structure in which the threshing material falling from the screen is sorted by the rocking sorter and the grain is taken out, and the rocking sorter can be extracted from the threshing part to the already cut side of the traveling machine body. It is configured.

  A second aspect of the present invention is the combine according to the first aspect, further comprising a grain discharge conveyor for taking out the grain selected by the swing sorter, and the grain at one side of the threshing unit. It is a structure which arrange | positions a discharge conveyor, Comprising: It is comprised so that the said rocking | pulling sorter can be extracted to the machine body outer side from the other side of the said threshing part on the opposite side to the said grain discharge conveyor.

  According to a third aspect of the present invention, in the combine according to the first aspect, the combiner according to the first aspect further includes a transmission mechanism that drives the swing sorting board via a counter shaft disposed in the left-right direction at the center of the machine body, and the swing sorting The transmission mechanism is configured to be detachable in the same direction as the board.

The rocking sorter 26 can be extracted from the other side of the threshing portion 9 on the side opposite to the grain discharge conveyor 8 to the outer side of the machine body. Therefore, the attaching / detaching operation of the swing sorter 26 can be easily performed without requiring the attaching / detaching operation of the grain discharging conveyor 8, and the threshing unit 9 or the grain discharging conveyor 8 can be performed during the attaching / detaching operation of the swing sorter 26. Can reduce the amount of grain leaking from the field to the field, etc., and can save labor in the maintenance work of the lower part of the threshing part 9.

  As shown in FIG. 25 to FIG. 27 and FIG. 30 to FIG. 34, a transmission mechanism unit 211 that drives the swing sorting plate 26 via a counter shaft 72 arranged in the left-right direction at the center of the machine body is provided. The transmission mechanism 211 is detachable in the same direction. Therefore, while the connection structure between the swing sorter 26 and the transmission mechanism 211 can be simplified, the attaching / detaching operation of the swing sorter 26 or the transmission mechanism 211 can be easily performed, and the transmission mechanism from the threshing unit 9 can be performed. By removing the part 211, one side part of the threshing part 9 where the transmission mechanism part 211 is installed can be opened widely, and the opening part on the one side of the threshing part 9 that is widely opened is used to Maintenance work inside the side can be performed easily.

  As shown in FIGS. 25 to 27 and FIGS. 30 to 34, a bevel gear case 217 that transmits a swinging driving force via a counter shaft 72 disposed in the left-right direction at the center of the machine body is provided, and an output shaft of the bevel gear case 217 is provided. The swing drive shaft 31 for swingingly driving the swing sorting board 26 is connected via the shaft joint 221. Therefore, in the state where the bevel gear case 217 is assembled, the attaching / detaching operation of the swing drive shaft 31 can be easily performed by absorbing the assembly error by the shaft joint 221, and the output shaft 218 of the bevel gear case 217 and the swing drive can be driven. It is not necessary to connect the shaft 31 with high accuracy, the bearing portion of the swing drive shaft 31 can be configured to be easily attached and detached, and the detachability operability of the swing drive shaft 31 can be improved.
