Description

Description: TECHNICAL FIELD The present invention relates to a fried device for a grain harvester.

Conventional technology and problems to be solved by the invention For example, a transfer spiral that transfers the grains selected by a selection device to one side of the machine, and a grain harvester that inherits the transferred grains and lifts the grains. In the fried food container of the machine, the fried food spiral in this fried food container usually winds a single spiral from the beginning end to the end of the fried food, but the transfer spiral and the fried food spiral are orthogonal to each other. Since the inherited part changes the direction of the grains pumped by the transfer end part of the transfer spiral from the horizontal direction to the vertical direction, a large lift force is required especially at the starting end part of the fried helix. There is a risk of grain clogging in some parts.

Means for Solving the Problems The present invention is directed to a fried grain starting end portion of a fried grain barrel (1) inside a fried grain spiral (2) for inheriting grains transferred from the lateral direction of the lower end portion and fried. , The outer diameter of which is larger than that of the fried helix (2), and the helix angle (a) with respect to the helix (2) axis (3)
(4) with a smaller angle than the fried helix (2)
Is provided in the grain harvesting machine.

Effects and Effects of the Invention Grains that are laterally transferred to the inheriting portion at the lower end of the fried grain cylinder (1) are inherited by the inheriting spiral (4) at the inheriting portion, and at this time, the inheriting spiral (4 Since the outer diameter of) is large, a large amount of grains can be inherited, whereby grains transferred in the vertical direction can be smoothly inherited and conveyed without being clogged.

The grain inherited by the inheriting spiral (4) is conveyed upward by the rotation action thereof and inherited by the fried spiral (2).
At the time of this inheritance, the helix angle (a) of the inherited helix (4) was set to be smaller than that of the fried helix (2), so the movement amount of the grain per one rotation of the helix axis (3) was Fewer succession spirals (4) than grain spirals (2). As a result, the outer diameter of the fried helix (2) is small, but the amount of grain movement per rotation is large, so that the grains of the inherited helix (4) that inherit and convey a large amount of grains can be smoothed without clogging. Can be carried over to. In this way, the grains transferred from the lateral direction to the inherited portion at the lower end of the fried grain cylinder (1) are the inherited spirals (4).
In a series of flow via the to the fried helix (2), it is smoothly guided without being clogged.

Example In addition, in the illustrated example, a threshing chamber (7) equipped with a slinging barrel (6) for planting a slinging blade (5) and threshing is provided, and a sorting device is provided below the threshing chamber (7). The threshing room (7) is integrally provided with a sorting room (8) for interior of the threshing room (7).
A sorting net (9) extending along the outer circumference of the cylinder of the handling cylinder (6) is provided between the sorting net (8) and the sorting chamber (8), and the sorting net (9) is provided below the sorting net (9). 9) A swinging sorting mechanism (10) of the sorting device for sorting threshed grains, straw debris, and the like dropped from
A sorting shelf or the like is provided, and a spiral gutter (11) for collecting the sorted grains is provided below the swing sorting mechanism (10) so as to be orthogonal to the axis of the handling cylinder (6). From the front wall to the rear wall of the threshing chamber (7) having the supply port (12) for supplying the culm to the threshing chamber (7), the culm leading from the supply port (12) to the discharge port. A passage (13) is provided, and a side wall (14) on the grain culvert passage (13) side holds a grain culm stock source and transfers the grain culm from the supply port (12) to the discharge port ( 15)
To provide.

The spiral gutter (11) is provided with a transfer spiral (17) for transferring the grains toward the side wall (16) opposite to the side wall (14) and extending outside the side wall (16). Outside the side wall (16), a bearing (19) for supporting one end of the shaft (18) of the transfer spiral (17) and a vertical bearing (20) orthogonal to the bearing (19). And a bent cylindrical inheritor (21) is provided, and a cylindrical connecting body (22) having an upper part smaller than a lower part is joined to the upper part of the inheritor (21), and On the upper side of this combined body (22), the grain outlet (23) is provided at the upper end.
The long cylindrical fried-cylinders (1) with are combined.

The bearing portion (24) provided at the upper end of the fried food barrel (1) and the vertical shaft bearing portion (20) support the upper and lower ends of the fried food shaft (3), respectively. A bevel gear (2) that meshes with the lower end of (3) and the side end of the transfer spiral (17) shaft (18).
5) A fried helix (2) for fixing each of (25) and for fried to the discharge port (23) from the connecting body (22) to the upper end of the fried shaft (3). This fried helix (2)
At the starting end of the fried food extending from the lower end of the fried food to the vicinity of the vertical bearing (20), the outer diameter of the fried helix is larger than that of the fried helix and the helix angle to the fried shaft (3) is set to a small angle. The inherited spiral (4) is provided.

Further, the lower end of the inheriting spiral (4) on the fried shaft (3) and the end of the transferring spiral (17) on the shaft (18) cover the bearings (19) (20). Covers (26) (26) are provided, and guide plates (27) (27) for facilitating the transfer of transferred grains are provided on the outer circumferences of the covers (26) (26).
In addition, (28) is a dust treatment chamber for sorting the dust containing dust from the threshing chamber (7).

Next, the operation will be described. The grain culm held by the transfer mechanism (15) is supplied from the supply port (12) into the threshing chamber (7), and the handling blades (5) (5) that rotate while being transferred by the transfer mechanism (15). ) ... threshed and discharged from the discharge port to the outside of the machine.

Threshing grains and straw debris falling from the sorting net (9) are sorted by the swing sorting mechanism (10), a sorting shelf, etc.,
The selected grains are collected in the spiral gutter (11), transferred into the inheritor (21) by the transfer spiral (17), pressure-fed at the transfer end portion of the transfer spiral (17), and the guide plate ( 27) The grain that was guided upwards by (27) and passed on to the inheriting spiral (4)
