Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain frying device in a combine harvester.

A typical combine harvester has a structure in which a reaping device is attached to a forward position of a pair of crawler traveling devices, and a threshing device is attached to an upper position.

In the threshing device, the first grain sorted in the wind sorting chamber is taken out by the first grain lifting cylinder, and the second grain is taken out by the second grain lifting cylinder and reprocessed.

With this structure, the lower ends of the first and second grain lifting cylinders exposed outside the aircraft collide with the crawler or come abnormally close to the crawler, which impedes smooth work. may occur.

First, in order to design the combine harvester as low as possible, the threshing device is installed low, so the lower ends of the first and second grain lifting cylinders exposed outside the machine may collide with the crawler. Or, they may almost collide with a crawler.

Therefore, the present invention provides that even if the threshing device on the crawler is installed as low as possible, the lower ends of the first and second grain lifting cylinders exposed outside the machine will not collide with the crawler or , a pair of crawlers placed at a predetermined distance, so as not to collide with the crawlers.
A threshing room with a built-in handling barrel, a wind sorting room for wind-sorting the threshed grains in the threshing room, and a first grain cross-transfer combiner for discharging the first grain sorted in the wind sorting room. Equipped with a threshing device that has a second cross conveyor for discharging grains.

b. All of the conveyors are installed in a direction perpendicular to the direction of movement of the aircraft, and the first grain cylinder is installed at the discharge end of the first grain cross conveyor, and the first grain cylinder is installed at the discharge end of the second cross conveyor. Install the second grain cylinder.

The C-first grain cross-transfer conveyor and the first-lifting grain cylinder attached to it are located between a pair of crawlers.

(d) The above-mentioned kettle-lifting grain cylinder is installed close to the body of the threshing device, and the above-mentioned second kettle-lifting grain cylinder is installed so as to be located outside of the above-mentioned -kama-lifting grain cylinder.

e The lower end of the second-fried grain cylinder is placed on a crawler.

The structure is as follows.

To explain one embodiment of the present invention, reference numeral 1.1' denotes a pair of left and right crawlers, which are arranged in parallel with a predetermined interval l as shown in FIG.

In front of the crawlers 1, 1', there is provided a reaping device 6 comprising a weed splitter 2, a pulling device 3, a cutting blade 4, a culm transfer device 5, and the like.

A threshing device 7 is mounted on the upper part of the crawlers 1, 1'.

The threshing device T has a threshing chamber 9 with a built-in handling barrel 8 formed in its upper part, and a husk supply device 10 for supplying husk culms to the threshing chamber 9 is attached to the side of the uncut land side P when viewed from above. .

L indicates the mowed land side. A handling net 11 is provided below the threshing room 9.
is stretched concentrically with the handling barrel 8, and a wind selection chamber 12 is formed in the lower part of the handling net 11.

The wind selection chamber 12 has a structure that blows a sorting wind from the front side to the rear side with respect to the aircraft traveling side. A wind turbine 13 that blows wind backward is mounted on the front side of the wind selection chamber 12. The first grain transverse conveyor 14 is provided at an intermediate position between the front and rear, and the conveyor 14
A second traverse conveyor 15 is mounted behind the shaft.

The axial direction of the first grain traversing conveyors 14 and 15 is orthogonal to the forward direction of the machine body.

When the first grain cross conveyor 14, 15 is viewed from the side, as is clear in FIG.
is installed at a lower position than the second cross conveyor 15.

The reason for this is that rather than sorting by sending wind horizontally to the side, sorting by sending wind slightly diagonally creates a step, which makes it difficult for grains to fly away, and allows you to sort with strong wind, which improves the sorting effect. It is.

The end of the first grain traversing conveyor 14 on the mowed land side protrudes beyond the wind sorting chamber 12, and the first grain transport conveyor 14 has a first grain cylinder 1 on the protruding part.
6 is installed.

The end of the second cross-feeding conveyor 15 also protrudes from the winnowing chamber 12 toward the mowed field, and the second grain cylinder 17 is attached thereto.

A bagging device 18 is provided at the rear of the threshing device 7, and the kettle-lifting grain cylinder 16 is installed so as to face an upper position of the bagging device 18 at the rear of the threshing device 7.

The second grain to be fried in the second grain lifting cylinder 17 is returned to the threshing room 9 and reprocessed as is generally known, so as shown in FIG. Therefore, the two first-fried grain cylinders 16 and second-fried grain cylinders 17 are in a state where they intersect at an intermediate position between the upper and lower sides.

In the case of such a structure, one of the grain lifting cylinders and the threshing device 7 must be close to the machine body side, and the other one must be placed further away from the machine body, or it will not be possible to cross them at an intermediate position as described above. .

Next, we will discuss the effect.

When the machine moves forward, the cutting device 6 cuts off the standing hair culm, and the culm transfer device 5 transfers it and transfers it to the culm supply device 10.

The tip portion of the husk taken over by the culm feeding device 10 is fed into the threshing chamber 9 and threshed by the handling teeth of the handling cylinder 8.

A part of the mixture of straw waste and grains generated in the threshing room 9 is transferred to the handling net 1.
1, and some of them go through the wind selection room 1 without passing through the handling net 11.
2 and are sorted by the wind generated by the windmill 13.

At this time, since the long grains have a specific gravity, they are not blown away by the wind from the windmill 13, but fall onto the first grain cross conveyor 14 on the front side and are collected, and are fried by the first grain cylinder 16 and rearward. The products are guided onto the bagging device 18 and packed there.

In this case, the kettle-fried grain cylinder 16 has two crawlers 1, 1
Therefore, even if it is installed at a low position, it will not collide with the crawler 1' and will operate smoothly.

The second grains with a lighter specific gravity that are wind-selected in the wind sorting room 12 are collected by the second cross conveyor 15 and returned to the threshing room 9 by the second grain lifting cylinder 17 to be reprocessed. Banage grain cylinder 1
7 is the outside of the kettle-fried grain cylinder 16, and the crawler 1'
Although it is placed in a position facing above, since its mounting position is high, it does not collide with the crawler 1' or come abnormally close to the crawler 1, and operates smoothly.

As described above, a typical combine harvester has a structure in which a reaping device is attached to a forward position of a traveling device consisting of a pair of crawlers, and a threshing device is attached to an upper position.

The threshing device has a structure in which the first grain sorted in the wind sorting chamber is taken out by the first grain lifting cylinder, and the second grain is taken out by the second grain lifting cylinder and reprocessed.

In this structure, the lower ends of the first and second grain lifting cylinders exposed outside the aircraft collide with the crawler or collide with the crawler.
The height of the aircraft could not be lowered below a certain level because the structure would approach the aircraft abnormally close to the aircraft, which would interfere with smooth work.

However, the present invention...
