Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a harvester having a feature of dust disposal.

[Conventional technology]

In conventional harvesters, for example,
As shown in Publication No. 28, a blower case equipped with a dust exhaust port on the peripheral wall is attached to the outside of a dust exhaust chamber so that the dust exhaust fan installed inside the blower case can be rotated and fixed around the axis of rotation. There was one.

[Problem to be solved by the invention]

With the above conventional configuration, is it possible to change the direction of the exhaust air by adjusting the rotation of the blower case and avoid the exhaust air from directly hitting the worker? There was a problem in which the particles spread in multiple directions, and later rose upwards, worsening the work environment.

The present invention has been made in view of the above-mentioned circumstances, and its object is to discharge air from which dust and the like have been removed through a side air passage, thereby preventing the dust and the like from dispersing and rising upward.

[Means to solve the problem]

The characteristic configuration of the present invention is that a dust removal device is attached to the outside of the dust removal chamber of the threshing device, which swirls and guides the exhaust air discharged from the dust removal port and vortex-sorts the dust contained therein.

[For production]

While the exhaust air from the dust exhaust port rotates inside the dust remover, dust, etc. with a relatively large specific gravity naturally falls and is collected inside the dust remover, and only the exhaust air from which dust has been removed is released outside the dust remover. be done.

〔Effect of the invention〕

Therefore, since dust and the like are not released into the air, the working environment is not deteriorated, and threshing work can be carried out regardless of whether there are private houses nearby, and the range of use of this harvester is wide.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

2 and 3 show a harvester according to the present invention. This harvester is equipped with a threshing device (3) and a driving section (4) on a body frame (2) equipped with a crawler traveling device (1), and also collects grain bags at the rear of the driving section (4). The configuration includes the section (5).

The threshing device (3) is equipped with a shell culm supply table (6) in an outwardly protruding posture on the lateral side, and a supply port (see figure A handling room (7) where the dust is input from the machine (not shown) and processed, a sorting section (8) below the handling room (7), and a dust extraction room (9) where the dust from the handling room (7) is discharged outside the machine. ) etc. The handling room (7) is equipped with a handling barrel (lO) and a receiving net (11) below it, and the stock side of the loaded culm bundle is covered with a foot chain (12).
) and a clamping rail (13) for conveyance, and then handled and processed by a handling cylinder (10).

The processed material that has been processed and leaked through the receiving net (11) is
The oscillating sorting device (14) in the sorting section (8) performs sieve sorting and the sorting fan (15) performs wind sorting to separate grains and secondary products such as paddy with branches, and the grains are separated from the lower one. The second item is dropped into the second item collection part (16) and the second item is dropped into the second item storage part (17) located below. In addition, the grains are transported to the bagging and collection section (5) via the aromatic material collection screw (18) and the fried grain conveyor (19), and the second grains are conveyed to the bagging and collection section (5) through the second product collection screw (20) and the thrower ( 21) by the handling room (7
).

Unprocessed materials that have not leaked through the receiving net (11) in the handling room (7) are discharged from the discharge port (22) at the terminal end in the conveyance direction to the whirlpool wind selection room (23), where they are floated and transferred by the whirlpool wind. However, heavy items such as paddy with branches should be stored in the second storeroom (1).
7), and light straw waste etc. are discharged from the dust removal chamber (9) to the outside of the machine.

A dust exhaust port (24) provided on the upper right side of the front surface of the vortex air selection chamber (23) has a wind exhaust guide (24) protruding forward.
25), and a dust blower (26) is provided in front of the dust exhaust port (24) in the vortex air selection chamber (23).

As shown in FIG. 1, a dust removal device (28) having an inlet (27) into which the exhaust guide (25) fits is installed outside the vortex air selection chamber (23).

This dust removal device (28) has a bottom plate (29a) forming the lower surface.
A dust removal case (29) is inclined to be lower at a position farther from the inflow port (27) in the left and right direction, and the exhaust air from the inflow port (27) of this dust removal case (29) is sucked and discharged to the outside. The suction fan (30) is provided immediately below the air vent hole (29b) provided in the upper left side of the dust removal case (29) in an upwardly protruding position, Immediately below this suction fan (30) is a filter (
31), and a discharge port (32) formed by extending the inclined surface of the lower bottom plate (29a), which can swing open and close around the upper edge of the discharge port (32), and A door (33) is installed so as to open the lower part due to the pressure of dust etc. that has slipped on the bottom plate (28a).

The suction fan (30) is supported by a vertical power transmission shaft (34) extending above the suction fan (30).
) is a vertical transmission shaft (36) interlockingly connected to the rotation shaft (35) of the dust blower (26) and a belt transmission mechanism (37).
This belt transmission mechanism (37
) and the vertical transmission shaft (36) are covered from above with a cover (38).

With the above configuration, while the exhaust air from the vortex air selection chamber (23) passes through the inlet (27) and rotates in the dust removal box (29), it is possible to remove dust, etc. with a relatively large specific gravity. It separates and falls naturally onto the bottom plate (29a). This naturally fallen dust, etc. slides down the slope of this bottom plate (29a) and reaches the discharge port (32).
The suction fan (30)
A filter (31) provided below removes fine dust and the like and discharges the exhaust air upwardly outside the case.

The dust removal case (29) has a bracket (40) at the free end of a pair of upper and lower support arms (39), (39) that are horizontally swingable about the axis (Pl) of the vertical transmission shaft (36).
.

(40) are pivotally connected to each other so as to be able to swing freely around the vertical axis (P2), and by two-stage swinging using these axes (PI) and (P2), the As shown by the imaginary line, it can be stored in the front side of the culm supply stand (6). The stored dust removal case (29) is attached to the culm supply stand (6).
It can be fixed using a connector (41).

It should be noted that the present invention is not limited to the structure of the attached drawings by adding numerals in the claims for convenient comparison with the drawings.
