Embodiments of the present invention will be described below with reference to the drawings. The embodiments can be appropriately changed in design without departing from the gist of the present invention.
The outline of the combine is as follows. FIG. 1 is a schematic side view of the entire combine. The combine is a traveling unit (A) that drives the body to travel, a cutting unit (B) that is installed in front of the traveling unit (A) and trims the grain culm, and is mounted on the traveling unit (A) to reduce the grain culm. Threshing and sorting department for threshing and sorting (C)
And so on.

The cutting section (B) includes a scraping reel (1).
1), a cutting blade (12) and a scraping auger (13). The cereal stalk is scraped by the scraping reel (11), cut by the cutting blade (12), and then scraped by the auger (13).
From the feeder house (14). Then, it is raised by the chain conveyor (15) in the feeder house (14) and supplied to the threshing / sorting section (C).

In the threshing / sorting section (C), the cereal culm is first transferred into a handling room (21), and a screw-type handling cylinder (22)
In (22), the crimped net (2
3) Threshing due to friction with (23). Threshed kernels are crimped on the crimping net (23) below the cylinder (22).
From the rocking sorting plate (24), and is sorted, and the long straw is transported to the dust outlet (25) behind. Swing sorting plate (24)
The threshed selected in the above is selected by receiving a sorting wind by Karino (26), and the grains fall to the first gutter (27) or the second gutter. The kernels dropped on the first gutter (27) are
Is transported to the Glen tank (50), and falls into the second gutter. And the grain passes through the discharge auger (51),
It is discharged out of the machine from the Glen tank (50).

FIG. 2 is a partial side view of the combine showing the vicinity of the lower part of the fryer cylinder (30). A stay (33) for attaching the base of the battery (32) is connected to the ladder (31). This stay (33) is a deep-frying cylinder (30)
Connect to The ladder (31) is the body frame (1)
The battery (32) and the fryer (30) are also firmly fixed to the body frame (1).

FIG. 3 is an explanatory view showing a part of the driving mode of Karino (26). Pre-fan (2) before Karino (26)
8), and the drive of the pre-fan shaft (28a) is taken from the drive of the Karamin shaft (26a). Since the speed change of the pre-fan (28) is performed in synchronization with the drive of the Karamin shaft (26a), the air volume is appropriately adjusted according to various conditions such as crops.

In the threshing / sorting section (C), the sorting width constituted by the handling cylinder (22) and the crimping net (23) is as follows:
The wider the threshing efficiency is better, but the size increases. Narrowing the sorting width within the range where threshing efficiency is not impaired contributes to reduction in size and weight. The selection width is preferably, for example, about 800 mm.

The swing frame is formed integrally, and the adjustment of the chaff fin (24a) is divided into front and rear portions in the traveling direction of the body. Therefore, an increase in weight due to the division of the chaff sheave frame is suppressed, and detachment is facilitated. The fact that the transmission is arranged at the front part in the body traveling direction also contributes to shortening the swing frame and reducing the weight.

As clearly shown in FIG. 1, threshing and sorting section (C)
The two handling cylinders (22) and (22) are arranged side by side with their axes in the body width direction. And a Glen tank (50) is arranged on the upper part thereof. Glen tank (5

FIGS. 4 and 5 are a partially cutaway rear view and a partially cutaway plan view of the periphery of the Glen tank (50), and FIGS.
2 is a front view and a partially broken plan view of FIG. Glen tank (5
Since the bottom surface of 0) has a valley shape, the grains supplied from the deep-frying cylinder (30) accumulate in the valley (50a).

An upper transfer device (55) for transferring grains in the machine body width direction is laid in the Glen tank valley (50a). On the screw conveyor of the upper transfer device (55), an eave-shaped body (5) covering the screw (55a) is placed.
6) is provided. The eaves-like body (56) is an elongated plate having a substantially L-shaped cross section, and prevents the grains from consolidating the screw (55a) and hindering the transfer.

A transfer port (57) is opened in the bottom surface of the Glen tank (50) below the downstream end of the upper transfer device (55). The grain transferred to the side of the machine body by the upper transfer device (55) falls to the transfer port (57) by its own weight.

A plate-like extension cover (56a) for extending the length of the eaves is attached to the eaves-like body (56) at the downstream end of the upper transfer device (55). To prevent stagnation. In addition, a plate-like inheriting blade (55b) is erected from the screw shaft at the downstream end screw (55a) to promote the fall of the grain to the inheriting port (57).

Below the transfer port (57), an upstream end of a lower transfer device (58) is provided. The grain that has fallen to the transfer port (57) is transferred to the lower transfer device (58). The lower transfer device (58) includes a screw conveyor disposed in the machine body traveling direction, and transports the grains to the rear side in the machine body traveling direction. By the two transfer devices (55) and (58) provided in the upper and lower two stages, the grains are removed from the Glen tank (5
Within 0), it is collected at one location on the rear side and supplied to the discharge auger (51).

FIG. 8 is a front view around the Glen tank (50). A substantially triangular plate-like reinforcing plate (60) is attached to the front and rear portions of the Glen tank (50). The Glen tank (50) is configured to be rotatable in the machine width direction around the pivot (61) via the reinforcing plate (60) and the elevating cylinder (62). This pivot (6
1) corresponds to the position of the lower transfer device (58).
Therefore, when the Glen tank (50) is rotated and tilted, the grains gather toward the lower transfer device (58) and contribute to the transfer of the grains.

A pivot portion (61) corresponding to a rotation axis of the Glen tank (50) is a body frame (1) of the threshing unit (C).
And is supported by a support frame (63) extending from the support frame. Therefore, regardless of the rotation of the Glen tank (50), the lid (64) of the threshing unit (C) can be opened and closed.

FIG. 9 is a side view of the area around the fried grain cylinder (30). Frying cylinder (3) for supplying grains to Glen tank (50)
At the downstream end of 0), a shooter (51) for guiding kernels
Is provided. Since this shooter (51) is fixed to the Glen tank (50), both (51)
The Glen tank (50) can be rotated without requiring the operation of releasing the connection of (50).

At the connection between the shooter (51) and the fryer (30), a sealing member (30a) for maintaining airtightness is provided.
, Which contributes to the prevention of damage and leakage of grain.
