[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust control device for a combine harvesting rice, wheat, soybean, or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open Publication No. Sho 60-168328, a culm cut by a cereal header is supplied to a threshing unit via a feeder house, and a dust is discharged therefrom.
There is a technique of providing a dust exhaust fan in the feeder house .

[0003]

In the prior art, the lower portions of the suction and exhaust fan and the suction and exhaust dust hood protrude into the inside of the feeder house. Therefore, the vertical width of the feeder house cannot be easily reduced, and the top plate of the feeder house cannot be obtained. A large space is formed between the feeder house and the upper surface of the internal conveyor, and it is not possible to easily improve the dust suction and discharge efficiency of the feeder house. Inability to easily reduce the diameter and rotation, reduce the suction pressure while maintaining the dust suction / discharge function, suck the culm or pods, or lack the suction power of earth and sand dust There is a problem that it is not easy to prevent the cut culms and grains from being sucked in and to improve the dust discharging ability.

[0004] In addition, the dust from the grain header is also sucked into the suction and discharge fan through the feeder house, so that there is a problem that the culm or the grain below the suction and discharge fan is sucked, and a filter for sucking only the dust is provided. by providing, there is a problem that the suction dust filter by clogging such culm decreases, with not aim to facilitate and improve and enhance the handling characteristics of the dust-exhaust function, reaper clutch
Just turn on and off the suction and exhaust fan by turning on and off the switch.
Stop the harvesting, the fan stops and the suction power is lost.
Dust adhering to the filter will fall, but the filter
Dust that has fallen nearby will remain,
And it is adsorbed again by the filter .

[0005]

In order to solve the problems] However, the present invention is, grain
Threshing the stalks harvested by the header through the feeder house
And a dust suction fan that discharges dust
Combine dust removal equipment installed in the feeder house
Outside the dust suction port on the top of the feeder house.
The suction and discharge dust hood is fixed inside the suction and discharge dust hood.
The suction surface of the fan is opposed to the dust suction port to prevent the suction of culms and the like.
A mesh net is provided at the dust suction port, and the vertical movement of the mowing part is detected.
Lift sensor that automatically turns on and off the suction and exhaust fan
The suction and exhaust fan can be installed so that the maximum outer diameter can be formed approximately equal to the width of the feeder house on the outside of the upper surface of the feeder house, and the upper and lower widths of the feeder house can be formed to the minimum dimensions necessary for transporting the cutting grain. In addition, it is possible to easily increase the diameter and decrease the rotation of the suction and discharge fan, improve the suction and discharge efficiency of the feeder house, easily reduce the suction pressure of the dust suction port, etc., and prevent suction of culms or pods. and securing the suction force of the soil dust, the obtained aims to facilitate and improve the anti-ingestion and dust-exhaust capacity of culms or grain, reaper
When the suction and exhaust fan stops temporarily due to
The cutting culm is transported by the continuous drive of the cutting unit.
Stalks or pods attached to the net
To the threshing section, and the suction
Even if the exhaust fan operates again, the fallen dust is sucked in again.
Troubles can be eliminated, and the dust exhaust function can be improved and handled.
It is possible to easily improve the performance .

Then, a dust suction / discharge fan (26) is installed so that a maximum outer diameter substantially equal to the width of the feeder house (18) is formed outside the upper surface of the feeder house (18), and the vertical width of the feeder house (18) is conveyed. In order to improve the suction and discharge efficiency of the feeder house (18) and to reduce the suction pressure of the dust suction port (28), the diameter of the suction and discharge fan (26) is increased and the rotation is reduced. performed to prevent aspiration, such as culm or pods, and to achieve the attraction of sand dust, there is ensured and improve the anti-ingestion and dust-exhaust capacity of culms or grain, reaper on the (9)
The dust suction fan (26) stops temporarily due to
And transport of the cut culm by the continuous drive of the cutting unit (9)
Is carried out, and culms or pods attached to the dustproof net (29)
By dropping, it is carried out to the threshing unit (4), and the reaping unit
The suction / discharge dust fan (26) operates again due to the lowering of (9).
Also eliminates the problem of dropped dust Ru sucked again, exhaust
Ru figure such as improvement as well as improvement of the handling of the dust features.

In addition, the suction surface of the suction / discharge fan (26) is opposed to the suction port (28), and an electric motor (30) for driving the suction / discharge fan (26) is disposed on the side opposite to the suction port (28). Then, the dust suction and discharge fan (26) is brought close to the dust suction port (28) to secure the dust discharge force, and the electric motor is disposed within the left and right width of the feeder house (18) by using the upper side of the dust suction and discharge fan (26). (30) is installed to prevent damage due to collision of the electric motor (30), etc., and to reduce the size of the body or increase the size of the cab (11) by placing the feeder house (18) and the cab (11) close to each other. The net is a net that prevents the inhalation of culms, etc.
9) is provided at the dust suction port (28), and the feeder house (18) is provided.
The dust of the grain header (17) can be sucked through the dust suction / discharge fan (26) so that the suction / discharge force can be increased, and the culm or the grain near the lower part of the suction / discharge fan (26) is prevented from being sucked. And improve the dust removal capacity.

[0014] Further, as shown in FIG.
A cutting switch (40), which is turned on in conjunction with the cutting clutch engagement operation of the cutting clutch lever (39) of 3), and a manual switch (41) disposed on the operation section (13), as shown in FIG. And a stop switch (42) that is turned off by the rise of the feeder house (18) and detects the stop of the mowing due to the rise of the mowing part (9). The mowing and manual switches (40) and (41) connected in parallel are provided. On the other hand, a stop switch (42) is connected in series, and each switch (40) is connected.
(41) A power supply battery (43) is connected to the electric motor (30) via (42), and either the cutting or manual switch (40) or (41) is turned on, and the cutting unit (9) is lowered. When the stop switch (42) is kept on, the suction / discharge fan (26) is driven by the motor (30), and the mowing part (9) is raised and stopped by changing the direction at the headland. When the switch (42) is turned off, or the cutting clutch is disengaged by the cutting clutch lever (39) to stop the cutting section (9), and the switches (40) and (41) are turned off, the motor ( 3
0) is turned off, the dust suction / discharge fan (26) is stopped, and the long culm adhering to the lower surface of the dust removal net (29) is dropped by its own weight to prevent clogging of the net (29). .

Further, as described above, the stop switch (42), which is an elevation sensor for automatically turning on and off the suction and discharge fan (26) upon detecting the elevation of the mowing section (9), is provided, and the direction is changed at the headland on the field. When the mowing part (9) is lifted and lowered, the dust suction and discharge fan (26) is temporarily stopped, and the stalks or grains adhering to the dust net (29) are dropped off to improve the dust discharging function. In addition, the handling workability is improved.

FIG. 9 shows a modification, in which the dust suction and discharge fan (26) can be easily formed by a sirocco fan, and the dust suction and discharge fan is disposed on the side hood (24) instead of the top hood (23). The fan (26) can be easily installed inside.
