A cylindrical drive shaft is formed on one side of both side plates 121.

The lower plate 122 is located on one side of the bottom surface of the housing and is equipped with a triangular blade.

The gumball inlet 14 is open on the front of the housing so that gumball can be injected into it.

The gumball cutting unit 16 includes a drive shaft inside the housing, a cutting blade, and a triangular blade, and is formed to cut the gumball and discharge it to the gumball discharge unit.

The drive shaft 161 is formed in a cylindrical shape on one side of both side plates and is a shaft that receives rotational power from a drive source to rotate the cutting blade.

The triangular blades 162 are arranged in a spiral shape at predetermined intervals in the axial direction on the outer periphery of the drive shaft and are used together with the cutting blade to cut the gumbul.

The cutting blades 163 are arranged in plural numbers at predetermined intervals in the width direction on the lower plate in parallel with the drive shaft, and are used to cut gumbul together with the triangular blade, and are recessed inward from the slit formed in the lower plate 122. It is formed.

The gumball discharge portion 18 is formed at the rear of the housing and is a place to cut and discharge gumball through the rotation of the triangular blade and a cutting blade that moves back and forth in the longitudinal direction. In addition, the gumbul discharge portion is open on one side of the rear bottom of the housing depending on the location, and is opened by arranging at a predetermined interval on one side of the rear rear of the housing and the first gumbul discharge portion provided to discharge the gumbul downward. It is formed and can be divided into a second gumbul discharge section provided to discharge the gumbul to the rear.

Preferably, in discharging the gumball, it is preferable that the gumball is discharged first through the first gumball discharge part, but since the gumball is discharged into the second gumbul discharge part, which has a small area that is initially opened by the rotation of the triangular blade, it is then discharged into the first gumball discharge part. Efficiency is low.

Figures 2 and 3 illustrate the fugitive outlet with a schematic illustration showing the process of combining the fugitive outlet with the main outlet according to an embodiment of the present invention and a vertical cross-sectional view of the present invention.

The amount of gum smoke discharged from the fugitive discharge port is less than the amount of gum smoke discharged from the main discharge port because the fugitive discharge port serves to assist the scattering of gum smoke from the main discharge port.

The contents described below will explain the components of the fugitive outlet.

The interior of the body 22 may include an auxiliary gum charcoal inlet, an auxiliary gum charcoal outlet, and a flow path.

The auxiliary sword inlet 24 is formed on the front side of the body.

In addition, the auxiliary gum fire inlet is through which wind is injected into the inside and gum fire is injected by a blower mounted on the combine. Preferably, the auxiliary gum fire inlet is opened to a large area to ensure the inflow of wind.

The auxiliary gum fire outlet 26 is configured in a rectangular shape to facilitate the discharge of wind and smoke from the rear of the body.

Preferably, the auxiliary gumbul outlet is opened to a large area to secure the inflow of wind.

The flow path 28 is formed to allow the gum fire and wind to pass through the auxiliary fire waste inlet and the auxiliary fire waste discharge port of the body.

Here, the flow path preferably has a shape in which the cross-sectional area of the flow path 28 narrows from the auxiliary gum smoke inlet to the auxiliary gum smoke discharge port so as to improve the efficiency of gum smoke discharge by improving the gum smoke discharge speed.

This uses Bernoulli's theorem, which states that when the same flow rate of wind flows in, the pressure of the passing wind decreases, while the speed of the wind increases as the cross-sectional area narrows.

Figures 4 and 5 show the present invention combined with a combine in a perspective view and a bottom perspective view.

The gumball discharge device is attached to the rear of the combine and is used to discharge gumballs.

Hereinafter, the operation of the combine gum discharge device in a preferred embodiment of the present invention will be described as follows.

After crops such as soybeans or rice are harvested in the combine (1), the gum that is separated from the grain and discharged from the grain processing section (thresher section) is moved to the main discharge port (10) and the fugitive discharge port (20) by the wind from the combine blower. .

The gumball separately discharged from the combine flows into the gumball inlet 14 of the main discharge port 10 and then cuts the gumbul through the triangular blade 162 of the drive shaft 161 and the cutting blade 163 of the lower plate 122. Afterwards, the gumball is discharged through the gumbul discharge part (18).

In addition, the gumball separately discharged from the combine flows into the auxiliary gumball inlet 24 from the fugitive discharge port 20, and then moves and discharges to the auxiliary gumball discharge port 26 through the flow path 28. Go through the process.
