Therefore, a large load supported by the machine base portion is supported by the plurality of vertical frame portions.

However, since the harvesting and harvesting machine travels on a rough working area, a force along the longitudinal direction of the vehicle body and the lateral width direction of the vehicle body may be applied from the machine base side that supports a large load to a plurality of vertical frames. When a strong force is applied, there is a disadvantage that the rigidity of the vehicle body frame tends to be low, such as a risk of damaging the connecting portion between the vertical frame and the machine base. In addition, in order to increase rigidity, it is necessary to add a special structure to increase the number of vertical frames, or to improve the strength of the connecting part between the vertical frame and the machine base, and the overall structure of the vehicle body is complicated. There was also a disadvantage.

An object of the present invention is to provide a harvesting and harvesting machine capable of simplifying the structure of a vehicle body frame while having sufficient support strength.

[2] Issues corresponding to the background art [2] are as follows.
Since the combine of the structure described in the above-mentioned Patent Document 2 includes a wheel traveling device, it is useful in that it can exhibit good traveling performance, but the threshing device overlaps the upper side of the front wheel. Therefore, the center of gravity of the aircraft tends to increase.
In addition, since the motor as the power source is disposed at the rear of the vehicle body, the distance from the motor to the input unit of the reaping device and the threshing device and the input unit of the traveling device is increased, and the transmission structure is increased in size and There is a problem that it tends to be complicated.

It is an object of the present invention to provide a wheel traveling combine that facilitates stable traveling by making the center of gravity of the fuselage as low as possible in a combine equipped with a wheel traveling device, and that facilitates downsizing and simplification of the power transmission structure. There is in point to do.

[3] Problems corresponding to the background art [3] are as follows.

[4] Issues corresponding to the background art [4] are as follows.
With the structure described in Patent Document 3, the sheet metal cover is fixed on the outer side of the sheet metal lateral side wall that forms the chamber and integrated, thereby quickly opening and closing the chamber. It is useful in that it can be carried out or the rigidity of the side wall can be increased.
However, in the above structure, in order to fix the sheet metal cover on the lateral side wall and to swing it integrally, the lateral side wall of the handling chamber itself is configured to be swingable about the vertical axis. A sheet metal cover is supported on the side wall. For this reason, the structure of the seal for making a reliable seal while enabling the swinging operation of the side wall constituting the handling chamber is complicated, and the shape and size of the side wall and the cover are too large. There is room for improvement in that it is difficult to make a difference or it is difficult to use the space between the side wall and the cover for some purpose.

An object of the present invention is to provide a combine having a structure that can simplify the structure and the maintenance work by using an exterior cover that can be opened and closed separately from the side wall.

The upper transport mechanism 310B has a grain conveyed by the lower transport mechanism 310A by rotating a screw shaft 312a that is rotatably mounted on both upper and lower ends of the transport cylinder 312 that is connected to the grain guide 311b. Is formed by a screw conveyor that lifts the water to the supply port 205A of the Glen tank 205.
At the conveyance end portion of the upper conveyance mechanism 310 B, a desorption device 313 is provided for supplying the raised grains to the inside of the Glen tank 205 from the supply port 205 A of the Glen tank 205.

The radiating device 313 covers a pair of radiating plates 313a that rotate the pumped grains integrally with the screw shaft 312a and radiate them radially by centrifugal force, and the rotational center of the screw shaft 312a. And a radiating case 313b that is externally fitted to the upper end portion of the transport cylinder 312 in a state that allows rotation around the center. A guide portion 313c for guiding the grains released by the release plate 313a to the inside of the Glen tank 205 is formed in the release case 313b.

The lower transport mechanism 310A uses a space formed between the right side surface of the threshing device 204 and the engine 207 below the right side overhanging portion 251R of the Glen tank 205, and passes through that space. It is arranged so as to be positioned between the right side surface of 204 and the engine 207. Moreover, it equips with the right side surface of the threshing apparatus 204 in the state along the direction orthogonal to the overhang direction of the right side overhang | projection part 251R. Accordingly, the lower transport mechanism 310A can be equipped in the state of being close to the right side surface of the threshing device 204, and the right outer portion of the lower transport mechanism 310A in the vehicle body frame 201 is positioned around the engine 207 and the engine 207. As an arrangement area for deploying devices and the like, it can be used more effectively without waste.

Accordingly, the Glen tank 205 is easily extended and formed in a state in which the right half side is positioned below the upper end of the threshing device 204, and is also provided on the front outer side of the grain guide 311b and the Glen tank 205. While making it easy to connect to the upper transport mechanism 310B, it is possible to improve the grain transport efficiency in the lower transport mechanism 310A as compared to the case of mounting in a vertical posture. In addition, the screw conveyance by the upper conveyance mechanism 310B is shortened to suppress the grain damage that may occur during the screw conveyance.

The upper transport mechanism 310B uses the space formed between the front surface of the Glen tank 205 and the back surface of the operation cabin 215 to transfer the Glen from the transport terminal portion of the lower transport mechanism 310A located on the right outer side of the threshing device 204. The tank 205 is equipped in a state of being tilted to the left toward the supply port 205 A located at the upper left end of the tank 205 and along the front surface of the Glen tank 205. Accordingly, the operation cabin 215 can be used for the support frame of the upper transport mechanism 310B. As a result, the grain tank 205 is configured to be switchable between a storage state and a tilted state by a swinging operation in the left-right direction, while the grain from the dispersal device 313 of the upper transport mechanism 310B to the inside of the Glen tank 205 is obtained. It is possible to simplify the configuration required for the support structure for fixing and mounting the upper transport mechanism 310B in the state of being close to the front surface of the Glen tank 205 so that the grains can be supplied.

Further, the lower end portion of the upper transport mechanism 310B is configured to be positioned at substantially the same height as the upper end portion of the threshing apparatus 204. Thereby, the height difference between the lower end portion of the upper transport mechanism 310B and the supply port 205A can be reduced, and the transport inclination angle of the upper transport mechanism 310B can be loosened accordingly. As a result, the grain conveyance efficiency in the upper conveyance mechanism 310B can be improved.
