Description

The present invention relates to a grain tank in a combine for cutting and threshing grain culms.

(B) Conventional technology Conventionally, a threshing device is mounted on one side of a machine having a traveling device, a driver's seat is provided in the front of the other side, and an engine is disposed behind the driver's seat. Combines with grain tanks are already known.

Further, a grain tank having a narrow front-rear width is provided at a portion behind the driver's seat and corresponding only to the handling room of the threshing device, and a dump tank mounted on the handling room of the threshing device is provided at a side portion of the grain tank. The combined combine is already known from Japanese Utility Model Publication No. 55-23329.

(C) Problems to be Solved by the Invention Among the known combine harvesters, the former has a large-capacity grain tank disposed on the opposite side of the threshing device, so that the grain weight in the grain tank is reduced. If it increases, the aircraft center of gravity will move to that side, and if the field is soft, the crawler on the grain tank side will sink abnormally large and the aircraft will become unstable, and steering will be difficult, and, furthermore, There were problems such as the occurrence of deep crawler marks, which hindered subsequent work.

In the latter case, the left-right balance of the aircraft is improved to some extent, but since the front and rear widths of the grain tank and the dump tank are limited to the width equivalent to the handling room of the threshing device, sufficient capacity cannot be obtained, and However, there is a problem that the work efficiency is low due to the necessity of performing the grain discharging work.

Further, when the capacity of the dump tank is increased, the weight when the grain is full increases, and it is necessary to strengthen the support of the dump tank.

(D) According to the present invention, a threshing device having a sorting unit extending from the lower part of a front handling room to the rear is mounted on one side of a machine having a traveling device. Connected with a helix spiral cylinder, provided a driver's seat at the front of the other side of the machine stand, in a combine provided with a pre-processing device at the front of the threshing device, provided a grain tank behind the driver's seat, The dump tank mounted on the threshing device over substantially the entire length thereof was supported by the same lifting grain spiral cylinder using a pivot shaft in a front-rear direction supporting one end side of the lifting spiral cylinder as a pivot. The above problem is solved by connecting the kernel tank to the kernel tank by a hydraulic cylinder so as to be tilted up and down and connecting both tanks.

(E) Action The grain stalks harvested and transported by the pretreatment device and supplied to the threshing device are threshed by the threshing device and discharged to the rear, and the grains handled by the handling cylinder in the handling room are rearward from below the handling room. Are subjected to wind and sieve sorting by a sorting apparatus, and the sorted grains are put into a grain tank and a dump tank by a filing spiral cylinder.

At that time, the grain tank and the dump tank communicating therewith extend not only to the part corresponding to the handling room of the threshing apparatus but also to the part rearward, so that a large amount can be stored.
When discharging the full grain, first, the one in the grain tank is discharged, and in the final stage, the one in the dump tank part flows into the grain tank and is discharged, and then the dump tank is raised. When tilted, the grains contained therein flow into the grain tank, so that the grains can be discharged smoothly.

Also, when loading the grain onto the carrier of a transport vehicle stopped on the road when discharging the grains, discharge and discharge by the lifting device, and when packing the bags, use the bag hanging rod suspended just below the grain tank. Pour into the suspended grain bag.
