Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is directed to a protruding portion of a disk-type waste straw cutter horizontally installed on the rear part of a threshing device and a lateral one side of the front part of the threshing device. The present invention relates to a combine grain collecting apparatus in which a hopper for packing the grain bags is installed between the motive force unit disposed in the.

[Conventional technology]

In some conventional combine harvesters, the hopper can be opened to facilitate the inspection and cleaning of the inside of the machine. Specifically, as shown in FIG. 4, the hopper (2) has a vertical fulcrum (Q) on the outer side of the rear end of the discharge wall cutter (3).
There was one that was configured so that it could swing and open laterally outward.

[Problems to be solved by the invention]

However, when the hopper (2) is swung around the vertical fulcrum (Q), the swing locus of the front end portion (2b) of the hopper (2) slightly projects forward from the original position. Moreover, since the driving part (4) is disposed in front of the hopper (2) in an adjacent state, the front end part (2b) and the rear end part of the driving part (4) interfere with each other. Therefore, in the past, the amount of forward extension of the hopper (2) was reduced to avoid the interference, but for that purpose, there was a problem that the capacity of the hopper (2) had to be sacrificed. It was

Further, conventionally, when carrying out work such as replacement of the collection bag near the hopper, the worker has to be careful so as not to fall from the machine,
There was a drawback that it was difficult to work.

The present invention has been made in view of the above circumstances, and provides a combine grain collecting apparatus that enables the operator to work easily near the hopper while making the hopper capacity as large as possible. The purpose is to

[Means for solving problems]

A combine grain collecting apparatus according to the present invention is a combine grain collecting apparatus having the above-mentioned configuration, wherein the hopper is
The support member that supports swinging and opening laterally outwardly around the vertical fulcrum set on the strut portion arranged on the outer portion of the front end and that supports the strut portion to the body fixing part is changed inside and outside the body The feature is that the backrest is freely provided.

The operation and effect of this characteristic configuration are as follows.

[Action]

In such a combine grain collecting apparatus, since the hopper has a structure capable of swinging about the vertical fulcrum set on the outer portion of the front end thereof, the swing trajectory of the front end portion of the hopper moves forward from the original position. Almost no protrusion occurs, and the front end of the hopper and the rear end of the driving part do not interfere with each other as in the conventional case.

Moreover, the protruding part of the disc-shaped waste straw cutter toward the tip side is located behind the hopper, but the waste straw cutter was conveyed diagonally behind the threshing device in consideration of the discharge position of the waste straw after cutting. Since the rear discharge straw is cut off, there is a dead space between the projecting portion and the hopper for conveying the discharge straw diagonally backward, and due to the existence of the space, the vertical fulcrum The hopper that swings around does not interfere with the projecting portion of the rear end portion, even though the swinging locus of the rear end portion thereof projects rearward from the original position.

In addition, since the posture of the backrest is freely changeable inside and outside the fuselage on the support member of the column that has the vertical fulcrum for swinging the hopper outward, the backrest leaned to the outside by the operator. While working, the backrest can be stored inside the fuselage so that it does not get in the way if the backrest is unnecessary.

[Effect of device]

Therefore, the hopper can take a sufficient amount of extension to the front and to the rear thereof, and the conventional problem of sacrificing its capacity is solved, so that the hopper capacity should be maximized. In addition to being able to do so, the worker can work while leaning on the backrest, which has made the work easier.

〔Example〕

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

As shown in FIGS. 1 to 3, a threshing device (1) is mounted on a traveling machine body (6) equipped with a crawler traveling device (5), and a mowing pretreatment unit is provided in front of the threshing device (1). (7) is vertically movable, and a disk-shaped walla cutter (3) is horizontally installed at the rear part of the threshing device (1) to form a combine according to the present invention.

The discharged straw cutter (3) is designed to cut the discharged straw after being conveyed obliquely rearward of the threshing device (1) in consideration of the discharge position of the discharged straw after cutting, and the tip side thereof is As shown in FIG. 1, the front surface protrudes rearward in a plan view, and thus the protruding portion (3a) is formed while creating a dead space (S) between it and the hopper (2). .
Then, between the projecting portion (3a) and the driving section (4) arranged on one side of the front side of the threshing device (1), the grains threshed by the threshing device (1) are placed. A hopper (2) for bag filling is installed as a grain collecting device of the combine.

The hopper (2) is a vertical fulcrum set on the outside of the front end.
It is supported so that it can swing and open laterally outwardly around (P). To explain this support structure in detail, the vertical fulcrum
The front support pillar (9) as the support pillar to be (P) is a threshing device (1).
It is erected on the fuselage (6) via the connecting member (13) by the left and right extending rods (12) as laterally extending support members from the machine wall of the front pillar (9). The cylinder (14) is pivotally supported, and the hopper (2) integrally supported with the cylinder (14) swings outward laterally about the vertical fulcrum (P). You can do it.

Next, the structure in which the hopper (2) is integrally supported by the tubular body (14) will be described in detail. The tubular body (14) has a front carrying portion (8a) via a connector (17). The supporting member is connected (8a)
Carries the front of the hopper (2). Further, the diagonal connecting rod (16) is attached to the connecting tool (17), and the diagonal connecting rod (16) and the left and right connecting rods (15) extended from the rear support column (11) are included. The front-rear connecting rod (10) is horizontally supported in the front-rear direction by the front-rear connecting rod (10).
(18) is horizontally supported horizontally. Further, the rear part of the hopper (2) is carried by the rear carrying member (8b) attached to the rear strut (11), so that the hopper (2) is connected to the cylindrical body (14) with the connecting rod (10). ), (15), (16) and supporting member (8a),
It is integrally supported via (8b). In addition, on the front surface of the left and right extending rods (12), a base end portion of an L-shaped backrest member (19) is provided.
By pivotally connecting (19a), the backrest member (1
9) is rotatably supported. When the operator needs a backrest, the backrest member (19) is rotated from the state shown by the solid line in FIG. 3 to the state shown by the phantom line, and the upper surface recess (13a) of the connecting member (13) is rotated. It can be positioned and used in). Also, the rear strut (1
The bottom plate (11a) of 1) can slide on the machine body (16) and rotate around the front support column (9).

When the grain collecting device of the combine is configured as described above, a dead space (S) that is generated between the protruding portion (3a) and the hopper (2) to convey the discharged straw obliquely rearward.
Since the space (S) exists, the hopper (2) swinging around the vertical fulcrum (P) has a rear end (2
The rear end portion (2a) does not interfere with the protruding portion (3a) even though the swing locus of a) is projected rearward from the original position.

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