Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grain recovery apparatus for combine harvesters, and more specifically,
The present invention relates to a combine grain collecting apparatus equipped with a horizontal feed conveyor that horizontally feeds out grains that have been pumped from a Glen tank by a screw body incorporated in an outer cylinder.

[Conventional technology]

While the harvesting and threshing work is performed by the combine in the field, the transverse feed conveyor is stored in the storage position on the machine body. Then, if the horizontal feed conveyor is left long in its stored state, it may come into contact with surrounding objects and hinder the cutting and threshing work, so conventionally, the horizontal feed conveyor is folded halfway. It was configured to be bendable, and it was supposed to be folded in the middle and folded up and down for storage.

[Problems to be solved by the invention]

The storing operation of folding and storing the lateral feed conveyor is
The folding work is troublesome and difficult to automate, and the work needs to be performed at a high position on the machine body, resulting in poor workability. Further, since the transverse feed conveyor in the stored state is folded up and down and is bulged upward, there is a problem that the field of view of the operator when performing the above-mentioned mowing threshing work is narrowed.

An object of the present invention is to provide a combine grain collecting apparatus capable of solving such a problem.

[Means for solving problems]

A grain collecting apparatus for a combine according to the present invention is a grain collecting apparatus for a combine having the above-mentioned configuration, wherein the outer cylinder body is configured to be expandable and contractible, and the screw body is spirally wound on a proximal rotation shaft. A blade type screw body in which the blades are directly connected to each other and a strip type screw body in which a spiral strip is provided around the tip side rotation shaft in a free circumference are combined by screwing and connecting the both rotation shafts. The feature is that the entire screw body can be expanded and contracted by changing the screwing amount of the both rotary shafts while fitting the spiral strip into the gap of the blade type screw body.

[Action]

In the combine grain collecting apparatus having such a configuration, when storing the lateral feed conveyor, by contracting the outer cylinder body, the entire screw body is contracted, so that the lateral feed conveyor is in a short length state. . In particular,
By shrinking the outer cylinder body, while changing the screwing amount of the distal end side rotation shaft with respect to the base end side rotation shaft while fitting the spiral thread into the gap of the blade type screw body, the length of the entire screw body is changed. That is, the length of the lateral feed conveyor is shortened.

〔The invention's effect〕

Thus, when shortening the length of the lateral feed conveyor, this can be achieved by simply shrinking the outer cylinder body, and its workability is extremely good. For example, the outer cylinder is composed of two cylinders, one of which is fitted over the other and can overlap, the outer peripheral surfaces of both cylinders are connected via a cylinder, and the rod of the cylinder is retracted. Therefore, the outer cylindrical body may be contracted, and its automation is extremely easy and its workability is good.

Further, in a state in which the length is shortened to store the horizontal feed conveyor, the outer cylinder body is compacted together with the screw body incorporated therein, so that the horizontal feed conveyor in the stored state is The existing problem of narrowing the field of view of the operator during the cutting and threshing work is eliminated.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 3, a threshing device (2) and a grain tank (3) for storing threshing grains from this are mounted side by side on a machine frame provided with a crawler traveling device (1), A combine section according to the present invention is constructed by continuously connecting a mowing section (4) which can be raised and lowered to the front part of the machine body frame.

The device for taking out the grains in the grain tank (3) is equipped with a vertical feed conveyor (5) for lifting the grains in the grain tank (3) upward at the rear part of the grain tank (3). At the upper end of (5), a lateral feed conveyor (6) that laterally conveys the grain from now on, is freely rotatable around the vertical axis (a),
In addition, it is configured by being continuously arranged around the lateral axis (b) so as to be capable of undulating and swinging.

The lateral feed conveyor (6) is for laterally feeding out the grain by the output of the screw body (62) built in the outer tubular body (61), but the outer tubular body (61) As shown in FIG. 1, a large diameter front end side cylinder (61a) and a small diameter base end side cylinder (61a)
b) combined with one of the tip side cylinders (6
1a) is externally fitted to the other base end side cylinder (61b) to be in an overlapable state, and both cylinders (61a), (61)
The outer peripheral surfaces of b) are connected to each other via a cylinder (63), so that the outer cylinder body (61) expands and contracts as the rod (63a) of the cylinder (63) moves back and forth. .

The screw body (62) is a blade type screw body (62A) in which a series of spiral blades (62c) are directly connected to a cylindrical base end side rotation shaft (62a) provided with an inner spiral groove. And a spiral in which a round bar is bent and formed on a cylindrical distal end side rotation shaft (62b) provided with an outer surface spiral groove (8) that can be screwed into the pin (7) of the base end side rotation shaft (62a). As shown in FIG. 2, the shape (62d) is arranged in an opposing position, and is combined with a strip screw body (62B) which is provided around the free end with its tip directly connected. And while inserting the spiral strip (62d) into the gap of the blade type screw body (62A),
a) and (62b), that is, by changing the screwing amount of the distal end side rotary shaft (62b) with respect to the proximal end side rotary shaft (62a),
The amount of overlap between (62a) and (62b) is changed so that the entire screw body (62) can be expanded and contracted.

In the combine grain collecting apparatus having such a configuration, when it is desired to store the lateral feed conveyor (6) and shorten its length, the outer cylinder body (61) is contracted using the cylinder (63). In this way, the above-mentioned linear screw body (62
B) rotates, while its spiral line (62d) is fitted into the gap of the blade type screw body (62A), its rotation shaft (62b) is screwed into the proximal rotation shaft (62a), and thus Screw body (6
The length of 2) is shortened, and the length of the transverse feed conveyor (6) is also shortened.

When the horizontal feed conveyor (6) is used to laterally feed the grains, the cylinder (63) is used to extend the outer cylinder body (61). By doing this, the overlap amount of the outer cylinder body (61) and the screw bodies (62A) and (62B) both decrease, and the overall length of the transverse feed conveyor (6) becomes long and the grain It will be in a convenient state to carry out.
In addition, when transporting grains in this state, a horizontal feed conveyor
On the upstream side in (6), the grain is mainly the blade type screw body.
While being conveyed by the action of (62A), the grains are mainly conveyed by the action of the strip screw body (62B) on the downstream side. And, the action of the downstream screw type screw body (62B) is smaller than the action of the blade type screw body (62A), but since the pushing force by the blade type screw body (62A) acts on the downstream side. , Practically not a problem.

[Another embodiment]

If the outer cylinder body (61) is made of a stretchable material, the outer cylinder body (61) does not have to have a divided structure as in the above-described embodiments.

The numbers of the spiral blades (62c) of the blade type screw body (62A) and the spiral lines (62d) of the strip type screw body (62B) may be changed depending on the carry-out capacity.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
