Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a grain tank discharge device in a combine harvester that harvests and threshes grain culms.

(b) Prior Art Conventionally, in a device for discharging the grains filled in the grain tank of a combine using a discharge thrower, the upper end of the discharge thrower is curved in an arc shape so as to be loaded onto the loading platform of a truck or other transport vehicle. The tip and bottom of the section were open.

(c) Problems to be solved by the invention The grain tank discharging device in the known combine harvester allows the grains in the grain tank to be loaded onto a wide range of loading platforms when the grains are lifted and discharged. When filling a small volume object such as a bag, alignment was difficult and the grains leaked out from the lower opening.

(d) Means for solving the problem The present invention is a combine harvester in which a threshing device and a grain tank are mounted on a machine base, and a discharge throat is attached to the discharge part of the grain tank, in which the upper part of the discharge thrower is directed downward. When the grains in the grain tank are loaded onto the loading platform of a transport vehicle using a discharge thrower, the grain tank is curved to open its end and lower surface, and a removable or openable cover is attached to the lower opening. When filling a small volume container such as a paddy bag or a container bag, remove the cover at the bottom of the top end or leave it open, and close the opening at the bottom of the top end of the discharge thrower with the cover and open the opening at the tip. The above-mentioned problem was solved by discharging the grains from the machine.

(e) Effect When the grain tank is full after reaping and threshing work and the grains are to be loaded in bulk on the loading platform of a transport vehicle, remove the cover on the lower curved surface of the upper end of the discharge thrower, or It is opened to expose the discharge port onto the loading platform, and in this state, the grains in the grain tank are lifted and discharged by the discharge thrower and stacked in bulk on the loading platform.

In addition, when filling grain bags or container bags on the loading platform or at an appropriate location, close the opening on the curved lower surface of the discharge thrower, leaving only the tip open, and tilt the discharge thrower to align it. death,
Grind the grains well and fill them.

(F) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a threshing device mounted on one side of a machine base having a traveling device 2. A pre-processing device 3 consisting of a reaping device and a grain culm conveying device is installed in front of the threshing device so as to be movable up and down. A straw processing device is installed, and an operation panel 4, a driver's seat 5, a grain tank 6, an engine 7, etc. are arranged in order from the front on the other side of the machine base.

Further, a substantially horizontal lateral transfer spiral for transferring grains forward is provided at the bottom of the grain tank 6, and a discharge thrower 8 is provided at the discharge portion thereof so as to be tilted laterally about the lateral transfer spiral axis. The discharge tube 9 of the discharge thrower 8 is configured to be bent and laid down toward the rear at the rear of the driver's seat 5, as shown in FIG. The upper part of the machine is raised up as shown in Fig. 9 using an operating lever or the like.

The discharging pipe 9 of the discharging thrower 8 has a distal end curved downward in an upright state, and this curved section 10 has a downward U-shaped cross section so that the distal distal end and the lower surface are open. In the embodiment shown in FIGS. 1 to 3, a curved cover 12 having a concave lower surface is fitted into the opening 11 from below and removably attached with bolts 13.

Further, in the embodiment shown in FIGS. 4 to 7, narrow bent portions 15, 15 are left on both sides of the bottom plate of the curved portion, and the inside thereof is formed as an opening 11a, and the upper portion of the bent portions 15, 15 is By fixing the guide plates 16, 16 with a narrow gap between them, the gap is formed into guide grooves 17, 17, and the curved cover 18 is slidably inserted into the guide grooves 17, 17, and the spring 20 One end of the operating wire 21 is connected to a pin 18a protruding from the lower surface of the cover 18, and the other end is operatively connected to a lever at the rear of the driver's seat 5. There is.

In the above-mentioned discharge thrower 8, when the grains in the grain tank 6 are to be loaded in bulk onto a transport vehicle parked on the road, in the first embodiment, the bolts 13 are removed and the cover 12 is removed. In the second embodiment, when the operating wire 21 is pulled by tilting the lever at the rear of the driver's seat 5, the cover 18 is retracted against the spring 20 and the opening 11 is opened, and in this state the ejection is started. The thrower 8 is tilted so that its upper end faces the loading platform, and the throwing blade of the discharge thrower 8 integrated with it is rotated by driving the lateral transfer spiral, and the shutter at the bottom of the grain tank 6 is opened. The grains in the grain tank 6 are lifted and loaded onto a loading platform.

At this time, the grains are discharged over a wide range from the opening 10a at the tip of the curved portion 10 to the opening 11a at the bottom, as shown in FIGS. 2 and 6.

In addition, when filling grains into a container bag or the like on the loading platform of a transport vehicle, in the first embodiment, the cover 12 is attached to the lower part of the curved part 10 with bolts 13 to close the lower opening 11. and opening 1 at the tip
0a is opened, and in the second embodiment, when the lever at the rear of the driver's seat 5 is tilted to relax the operating wire 21, the cover 18 is slid open due to the tensile action of the spring 20. The portion 11 is closed, leaving only the opening 10a at the tip open.

Therefore, by tilting the discharge thrower 8 appropriately, the discharge pipe 9
The opening 10a at the tip faces the inside of the container bag or the opening of the paddy bag, and the grains are lifted and discharged for filling.
It is well tied up and filled from a, and does not leak outside.

(g) Effect of the invention The present invention provides a combine harvester in which the threshing device 1 and the grain tank 6 are mounted on the machine base as described above, and the discharge throat 8 is attached to the discharge part of the grain tank 6. The upper part of the grain tank 6 is curved downward, its ends and lower surface are opened, and the removable or openable covers 12 and 18 are attached to the lower opening, so that the grains in the grain tank 6 can be transferred to the transport vehicle. When loading in bulk, by opening the opening on the lower surface of the curved part 10 at the top of the discharge thrower 8, the lifted grains can be dispersed and thrown onto the loading platform of the transport vehicle, and the discharge thrower can be tilted. This allows the entire loading platform of the transport vehicle to be loaded approximately evenly.

In addition, when filling the lifted grains into a container with a small capacity such as a container bag on the ground or on the platform of a transport vehicle, if the lower opening of the upper part of the discharge pipe 9 is closed with the covers 12 and 18, the container It is extremely easy to align the opening 10a with the inlet of the
And the grains lifted by the discharge thrower 8 are transported to the curved part 1
The grains are discharged from the opening 10a at the tip of the grain in a well-collected manner, and the grains can be reliably filled while preventing the grains from flowing out.
