Description

[Detailed explanation of the invention] This invention relates to a combine harvester equipped with a paddy storage tank.
In detail, it relates to a combine harvester that can run stably without tilting even in wet fields.

Generally, a combine harvester stores the harvested paddy in a paddy bag installed on the side of the combine, and releases the paddy bag when it becomes full into the field. The combine harvester is designed to be driven for work with the rice bag mounted on the side of the combine, but if the paddy bag is driven like this with the rice bag mounted on the side of the combine, the load will be biased to one side of the combine and There are defects such as the combine harvester tilting and not being able to run stably.

The purpose of the present invention is to make a paddy storage tank located at the upper part of the threshing device and at the center position in the width direction of the machine body, which covers almost the entire surface of the handling barrel of the threshing device, movable in the front and back direction of the machine body, so that it can move up and down the machine in the combine. When storing paddy harvested by a reaping device using motion in a paddy storage tank, the load of the paddy stored in the tank does not upset the balance in the width direction, allowing stable running, and also ensuring that the paddy is When taking out the paddy, the paddy storage tank is tilted rearward so that the paddy can be easily taken out from the unloading port provided at the rear of the tank.

However, the configuration of the present invention is such that the machine body, which is equipped with a reaping device at the front and a threshing device at the top, is placed at the intermediate part in the front and back direction of the frame with the crawler, and is centered around the horizontal axis extending in the width direction of the machine body. A combine that is supported so as to be movable up and down, and a hydraulic lifting device is connected and arranged between the machine body and the frame, and the machine body is integrally moved up and down with respect to the frame by the hydraulic lifting device. A rail extending in the longitudinal direction of the machine body is provided at the upper part of the threshing device and at a position on the center side in the width direction of the machine body, and a rail is provided that substantially covers the entire surface of the handling trunk of the threshing device, and a paddy removal port is provided at the rear part. A shallow cylindrical paddy storage tank is formed, and the tank is placed on the rail so as to move freely in the longitudinal direction of the machine as the machine rotates integrally with the frame. A long hole-shaped paddy insertion port extending in the longitudinal direction of the machine body is provided in the discharge pipe of the grain-lifting cylinder that opens downward toward the top surface of the tank, and the discharge pipe of the grain-lifting cylinder is inserted into the paddy insertion port. As the tank moves in the longitudinal direction of the machine, it is discharged from the discharge pipe of the grain lifting cylinder into the tank, and the paddy that tends to accumulate around the paddy insertion date is dispersed in the longitudinal direction of the machine. This allows the load of the paddy stored in the tank to be stably applied to the machine body, allowing the combine to run stably without tilting in wet fields. By rotating the tank about the horizontal axis and tilting the tank backward, the height of the paddy outlet from the ground is lowered, and the paddy can be easily taken out.

The details of the present invention will be explained below based on the embodiments of the drawings.
Reference numeral 1 denotes a combine harvester body, and the lower part of the combine harvester body 1 is supported at an intermediate portion in the longitudinal direction of a frame F having a crawler 2 so as to be freely movable up and down about a horizontal axis 6 extending in the width direction of the machine body 1. In addition, a reaping device 3 is installed at the front of the machine body 1, and a threshing device 4 is installed at the top of the machine body 1.
The reaping device 3 and the threshing device 4 are driven by a hydraulic lifting device 5 connected between the rear of the reaping device 3 and the machine body 1, and are moved up and down as a unit around the horizontal shaft 6. It is configured as follows.

In the figure, 7 is a handling barrel stored in the threshing device 4, 8 is a feed device of the threshing device 4, and 9 is a special cheno for the reaped husk that is stretched between the reaping device 3 and the threshing device 4. be.

Reference numeral 10 denotes a cutter device integrally mounted behind the threshing device 4, which removes straw from the threshing device 4 to the straw conveying device 11.
This is to cut the waste straw supplied through the cutter into a predetermined size.

Therefore, in the combine harvester, a rail 14 extending in the longitudinal direction of the machine body 1 is provided above the threshing device 4 and at a position on the center side in the width direction of the machine body 1, and the entire surface of the handling barrel 7 of the threshing device 4 is provided. A shallow cylindrical paddy storage tank 12 with a paddy outlet 16 provided at the rear is formed.
Rollers 1 rolling on the rail 14 are provided on both sides of the lower surface of the
A plurality of rollers 13 are mounted on the rails 14 so as to move freely in the front and rear directions of the machine body 1 as the machine body 1 rotates integrally with respect to the frame F. There is.

Further, on the top surface of the tank 12, a long hole-shaped paddy insertion port 20 extending in the longitudinal direction of the machine body is provided for a discharge pipe of a grain lifting cylinder (described later) that opens downward toward the top surface of the tank 12. In addition, stoppers 15 are provided at appropriate locations on the rails 14 to prevent the paddy storage tank 12 from moving more than necessary.

Reference numeral 16 denotes a paddy take-out port formed at the rear end of the paddy storage tank 12. A cover plate 17 is provided on the take-out port 16 so as to be movable up and down. The outlet 16 can be opened and closed.

Reference numeral 18 denotes a grain lifting cylinder that extends from the top pick-up screw conveyor (not shown) of the threshing device 4 to the upper part of the threshing device 4. A bellows-shaped discharge pipe 19 is attached to the top surface of the tank 12 and opens downward toward the top surface of the tank 12. The tank 12 faces the paddy insertion port 20 formed in the tank 12, and the paddy threshed by the threshing device 4 is stored in the tank 12 from the discharge pipe 19 through the paddy insertion port 20.

Note that the paddy is taken out from the paddy removal port through the tank 12.
This can be easily done by tilting the paddy storage tank 12.
A screw conveyor for taking out paddy may be installed horizontally inside the rear end, and the conveyor may take out the paddy inside the tank from the side thereof.

In the above-mentioned combine harvester, the culm that has just been cut by the reaping device 3 is lifted by the special cheno 9 behind it, is fed to the feed device 8 of the threshing device 4, and is then held by the feed device 8. The waste straw is passed through the threshing device 4 and threshed by the internal handling cylinder 7, and the waste straw is transported by the straw removal device 11 to the cutter device 10, where it is cut into a predetermined size and threshed. The processed paddy is transferred from the first pick-up screw conveyor to the paddy storage tank 1 mounted on the upper part of the threshing device 4 via the grain lifting cylinder 19.
It will be stored in 2.

Then, in order to reach the edge of the field and rotate the combine harvester, the machine body 1 is tilted upward around the horizontal axis 6 using the lifting device 5.
Since the reaping device 3 and the threshing device 4 are rotated integrally with the machine body 1, the paddy storage tank 12 moves rearward and the discharge pipe 19 moves forward relative to the paddy storage tank 12. To position.

Further, when the machine body 1 is tilted downward after completing its rotation, by moving the paddy storage tank 12 forward, the discharge pipe 19 is positioned at the rear relative to the paddy storage tank 12, contrary to the above. It will be done.

Therefore, it is possible to prevent paddy from remaining in the vicinity of the discharge pipe 19 and causing clogging.

Furthermore, since the paddy storage tank 12 can be moved back and forth as the machine body 1 is tilted up and down, the paddy stored in the tank 12 can be evenly distributed among the tanks 12. be.

When the paddy is fully stored in the paddy storage tank 12 in this way, or when the reaping and threshing work is completed,
Each device of the combine is stopped, the reaping device 3 and the threshing device 4 are tilted rearward and downward around the horizontal shaft 6 by the lifting device 5, and the paddy storage tank 12 is moved rearward accordingly.
After this, the lid plate 17 of the paddy outlet 16 is moved upward to remove the paddy from the outlet 1.
By opening 6, the paddy inside the tank 12 can be taken out.

As described above, in this invention, when the machine body is tilted up and down when turning around at the edge of the field, the paddy storage tank moves in the front and back direction of the machine body, and the top surface of the tank Since a long hole-shaped paddy insertion port extending in the front-rear direction is provided, the relative position of the discharge pipe of the grain lifting cylinder facing the paddy insertion port and the paddy storage tank shifts in the front-rear direction.

Therefore, the vicinity of the discharge pipe is not clogged with paddy, and as the tank moves, the paddy in the tank can be uniformly dispersed, and a good front-to-back balance can be maintained.

Furthermore, a shallow cylindrical paddy storage tank is mounted on the top of the threshing device at the center in the width direction of the machine so as to cover almost the entire surface of the handling barrel of the device, so the paddy harvested by the reaping device is stored at the top of the threshing device. Even if the paddy is stored in a paddy storage tank, the balance in the width direction will not be lost due to the load of the paddy stored in the tank, and together with the uniform dispersion of the paddy into the paddy tank, This has the effect of allowing stable running.

Moreover, after the reaping and threshing work is completed, by rotating the machine body relative to the frame around the horizontal axis so that the front side is at the top and the rear side is at the bottom, the tank can be moved rearward, and the tank can be moved backward. The rear part can be made lower than the front part, and therefore, the paddy stored in the paddy storage tank can be taken out extremely easily and reliably from the paddy removal port provided at the rear part.
