Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a method in which the handling barrel is rotated around an axis in the longitudinal direction of the machine, and the entire harvested grain culm is supplied to the handling chamber. A threshing and sorting device having a threshing section configured to flow in the direction of the axis and a sorting section for threshed material disposed below the threshing section is provided, and a tank for storing threshed grains is provided. Regarding the combine harvester installed.

[Conventional technology]

In the above combine harvester, conventionally, for example, JP-A-60-2
As shown in Japanese Patent No. 44223, a threshing sorting device and a threshed grain storage tank were arranged side by side in the lateral direction of the machine body.

[Problem that the invention seeks to solve]

In the above-mentioned conventional combine harvester, as the threshed grain is stored, the weight on the tank side of the machine body becomes equal to the weight on the side of the threshing sorting device due to the above-mentioned positional relationship between the tank and the threshing sorting device and the weight of the stored grain. Depending on the ground conditions, the aircraft could tilt to a position where the tank side was lower.

An object of the present invention is to suppress changes in the weight difference between the left and right sides of the fuselage caused by stored grains while suppressing increases in the height and longitudinal length of the fuselage as much as possible.

[Means for solving problems]

The characteristic configuration of the present invention is that, in the above-described combine harvester, a conveyance path is provided for supplying the threshed material from the dust outlet at the end of the handling chamber to the sorting section, and the lower end side of the tank is It is arranged above the terminal end side of the sorting section in a state where it overlaps with the handling cylinder, and its functions and effects are as follows.

[For production]

When the material to be processed is supplied from the dust outlet at the end of the handling chamber to the sorting section and subjected to sorting processing, the above-mentioned Japanese Patent Application Laid-Open No. 60-244223
Even if the front and back length of the handling cylinder is shortened compared to the case where the threshed culm from the handling chamber is directly discharged to the outside of the device as shown in the above publication, the grains are discharged from the device together with the threshed culm. In other words, it is possible to minimize the loss of grains. In other words, if the threshing culm is directly discharged from the handling chamber to the outside of the equipment, the handling drum will be made long, and the grains mixed in the threshing culm from the starting end of the handling drum will be transferred to the terminal end of the handling drum. It is necessary to ensure that the grains are removed as reliably as possible, but if the threshed culms are fed to the sorting section, the grains cannot be removed from the threshed culms in the handling room by using a short handling barrel. The grains are also taken out in the sorting section. Therefore, by supplying the threshed material from the dust outlet to the sorting section, the length of the handling barrel is shortened, so that the lower end can fit into the space created above the terminal end of the sorting section at the rear of the handling barrel. By arranging the tank above the handling torso, the installation level of the tank can be lowered compared to placing the tank above the handling torso, and compared to placing the tank and the long handling torso side by side in the longitudinal direction of the aircraft. While shortening the length of the space required for arranging the tank and the threshing sorting device in the longitudinal direction of the machine, the tank can be installed so that its left-right center coincides with the left-right center of the machine, or as close as possible.

〔Effect of the invention〕

Since the left and right center of the tank can be moved or brought as close as possible to the left and right center of the aircraft body, it is possible to prevent the difference in weight between the left and right sides of the aircraft body from changing regardless of whether threshed grain is stored, or even if the change cannot be eliminated, the weight difference can be reduced. Changes can now be suppressed to a lesser extent than before, and operations can now be advantageously carried out in wet fields, with no or as little tilting of the machine as possible due to accumulation of threshed grains, making it easier to maneuver.

Moreover, since the tank can be arranged at a relatively low level, the overall height of the aircraft can be kept as low as possible, and the space required for installing the tank and threshing sorting device can be relatively shortened in the longitudinal direction. We were able to keep the overall $X length as short as possible, making the entire aircraft as compact as possible.
