Description

[Detailed Description of the Invention] The present invention relates to a threshing machine with a grain storage device such as a combine harvester or a harvester equipped with a grain tank, and more specifically, a grain tank is disposed on the side of the threshing device, and the grain tank is arranged on the side of the threshing device. A first opening at the bottom of the screw type grain lifting device is openably and closably connected to the first outlet and a lower outlet of the grain tank, and a second opening formed in the middle of the grain lifting device is connected to the grain tank. The present invention relates to a threshing machine with a grain storage device, which is openably and closably connected to an upper inlet of a tank, and a grain lateral feed device is connected to an upper part of the grain lifting device.

In this type of threshing machine with a grain storage device, the grain lifting device is used to temporarily store the grain from the threshing device in the grain tank, and the grain lifting device is used to send the grain from the grain tank to an external truck. This has the advantage of simplifying the structure and improving productivity.

However, in order to use one grain lifting device for two purposes like this, it is necessary to use an opening/closing shutter provided between the first opening and the lower outlet or the first take-out port, and a second
This method has the disadvantage that it is necessary to open and close the opening/closing shutter provided between the opening and the upper entrance, and that the operation of a plurality of opening/closing shutters is cumbersome.

The above-mentioned drawbacks have been solved so that grains can be stored in a grain tank and grains can be sent out from a grain tank with a single grain lifting device without having to operate multiple opening/closing shutters as described above. As a threshing machine, for example, one disclosed in Japanese Patent Application Laid-open No. 114230/1983 is known.

That is, the grain lifting cylinder that constitutes the grain lifting device and the discharge cylinder that sends out the grains conveyed by the grain lifting cylinder to a truck etc. are made detachable, and the said grain lifting cylinder is configured in conjunction with this attachment/detachment operation. A middle cylinder is moved in the vertical direction, and the discharge port of the upper cylinder and the suction port of the lower cylinder, which also constitute the grain lifting cylinder, are configured to be opened and closed contrary to each other by moving the middle cylinder in the vertical direction. , the grains can be stored in the grain tank and the grains can be delivered from the grain tank with only one grain lifting device.

However, in recent thresher machines with grain storage devices such as combine harvesters and harvesters equipped with grain tanks, the discharge tube, or lateral feed device, which sends out the grains transported by the grain lifting device to a truck, etc., is located around the vertical axis relative to the machine body. This type of threshing machine is configured to be rotatable, and can be freely switched between a storage position inside the body when not in use and an extended position outside the body when in use. If a structure in which the discharge tube and the grain lifting device are attached and detached like the above-mentioned conventional threshing machine is applied, the switching operation between storing grain in the grain tank and sending out grain from the grain tank will require the above-mentioned discharge. Since it is necessary to rotate the tube and attach/detach it, the complexity of the work is not solved, and
The switching structure has the disadvantage of being complicated.

The present invention has been developed in view of the above-mentioned circumstances, and is capable of storing grains in a grain tank and delivering grains from the grain tank with a single grain lifting device, in which the storage and delivery are combined. To provide a thresher with a grain storage device having a simple switching structure and easy switching operation.

In order to achieve this objective, the threshing machine with a grain storage device of the present invention has the above-mentioned configuration, in which the outer peripheral case of the grain lifting device is held with respect to the machine body so as to be rotatable around a screw shaft. In addition, the grain lateral feeding device is integrally and rotatably connected to the outer peripheral case, and is configured to be freely switchable between a posture in which the grains are stored inside the machine body and a grain discharging posture facing the outside of the machine body. Further, the lower part of the outer circumferential case is relatively rotatably fitted into the first cylindrical bracket in which the first outlet and the lower outlet are formed, and
The middle part of the outer peripheral case is relatively rotatably fitted into the second cylindrical bracket in which the upper inlet is formed, so that when the grain lateral feeding device is in the storage position, the lower outlet and the first and the grain lateral feeding device so that communication with the opening is cut off, the first opening and the first outlet are communicated, and the second opening and the upper inlet are communicated with each other. In the grain discharge position, the mutual arrangement positions of the respective ports are arranged so that the lower outlet and the first opening communicate with each other, and the second opening and the upper inlet communicate with each other. The settings are considered to be feature configurations.

That is, in conjunction with the operation of rotating the outer peripheral case of the grain lifting device around its screw axis, the grain lateral feeding device is also rotated integrally with the outer peripheral case of the grain lifting device, thereby rotating the grain lateral feeding device. It is configured to be switchable between a storing position and a grain discharging position, and in the storing position of the grain lateral feeding device, the lower outlet and closing the first opening and putting the first opening and the first outlet in communication;
The second opening and the upper inlet are in communication with each other, and the lower outlet and the first opening are connected so that when the grain lateral sending device is in the grain discharging position, the grains stored in the grain tank can be sent out to a truck or the like. Since the second opening and the upper inlet are closed, grains can be easily removed by simply changing the posture of the grain lateral feeding device between the storing posture and the grain discharging posture. It is possible to automatically switch between storing grains in the grain tank and sending grains out of the grain tank. It has a simple structure that can be opened and closed in correspondence with the exit and the upper entrance, and has the effect of reducing manufacturing costs by eliminating the need for special opening/closing shutters or switching devices.

Next, embodiments of the present invention will be described based on the drawings.

This embodiment will be explained using a combine harvester as an example.

In this combine harvester, the arrangement of the reaping device 1, the threshing device 2, the driver's seat 3, etc. is the same as that of conventionally known devices, so a detailed explanation will be omitted.

A grain tank 4 is arranged on the lateral side of the threshing device 2, and a grain lifting device 5 is arranged between the two.

The opening 18 is disengaged from the upper inlet 16, and the outer case 6 is set in a state where it is closed (this state is referred to as the tank removal position).

At the upper end of the outer peripheral case 6, a starting end of a grain lateral feed-out device 20 equipped with a screw for grain conveyance is continuously connected to the upper end of the outer peripheral case 6 so as to be able to swing vertically. 20 is provided so as to move integrally with the outer circumferential case 6 as the outer circumferential case 6 is rotated. This grain lateral feeding device 20 and the outer peripheral case 6
When the tank is in the tank supply position, the outlet part 21 is in the storage position above the reaping device 1, and when the tank is in the tank retrieval position, the outlet part 21 protrudes laterally outward of the machine body. It is designed so that it has an overhanging posture.
