Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sorting device for a thresher equipped with a handling cylinder for shedding grain culms.

[0002]

[Prior Art]

 Conventionally, an oscillating sorting board provided with chaff fins is arranged below the handling cylinder, and a sorting fan is provided to supply sorting air in the direction of the sorting board. There has been a technique of adjusting the angle of the chaff fin and adjusting the air flow rate of the fan by following the amount of culm supplied.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technology, since the chaff fin is a metal plate, straw dust of the moist material adheres to it, and during long-term work, the gap between the chaff fins is crushed, impairing the original sorting function, and If left as it is, chaff fins will be rusted, corroded early, and slippage of the objects to be sorted will become unstable, resulting in instability in specific gravity sorting.Furthermore, during assembly of chaff fins, fins made of synthetic resin will be used. When inserting the end of the chaff fin into the receiver, the chaff fin-side retaining part becomes a resistance when it enters the slit groove on the fin-receiving side and is damaged, or the chaf fin sharp edge cuts and widens the groove. There were inconveniences such as the effect of the stop being reduced.

Further, in the above-mentioned conventional technique, the chaff fin angle is adjusted by following up and down of the straw removal guide rod depending on the supply amount of the grain culm, but the chaff fin angle is adjusted depending on the variety and the handling depth. However, there is a difference in the volume of grain culm in the cutting part, and it does not always match the selection leakage amount, and the chaff fin opens and closes, so the current situation is that proper automatic adjustment is not possible.

Further, in the above-mentioned conventional technology, the air volume of the sorting fan is adjusted by following the upper and lower sides of the straw-discharging guide rod depending on the amount of grain culm supplied, Since there is a difference in the specific gravity of the particles and the specific gravity is ignored, the air volume control shutter of the fan opens and closes, so the current situation is that proper automatic adjustment cannot be performed.

[0006]

[Means for Solving the Problems]

 However, the present invention has a structure in which a chaff fin for selectively leaking grains in the shattered material is provided on the swing sorting board, and by coating the chaff fin surface with the fluororesin, the characteristic of the fluororesin is not provided. Adhesiveness and slippage prevent straw debris from adhering to the chaff fins for stable sorting performance, and prevent chaff fins from rusting, improving durability and stabilizing specific gravity sorting. In addition, when the chaff fin end is inserted into the synthetic resin fin receiver, the chaff fin side retaining part becomes a resistance when entering the slit groove on the fin receiving side, and the chaf fin sharp edge The groove is prevented from being widened, the damage of the fin receiver is prevented, and the function and effect of retaining is maintained, thus improving the workability of assembling the chaff fin.

In addition, a chaff fin for selecting and leaking grains in the shattered product is provided in the swing sorting board, and the angle of the chaff fin is adjusted according to the amount of grain culm supplied. It has an interlocking arm that changes the angle of the chaff fins based on the amount of grain supply, and a rotating arm that is remotely operated by a hand lever. By configuring it to operate within the range of the holes, the operator can voluntarily check the yield, maturity and variety of the crop to determine the setting angle of the chaff fins in advance and automatically adjust the amount of grain culm supplied. The chaff fin is adjusted to an appropriate angle by assisting artificial adjustment in order to stabilize the sorting performance.

Further, in a structure in which a sorting fan for generating a sorting wind for removing dust from the shattered material is provided, and the opening of the air volume adjusting shutter of the fan is adjusted by following the amount of the grain culm supplied. Since the shutter opening / closing angle reference range setting mechanism is provided, the operator can voluntarily check the yield and ripeness of the crop, the variety and the wet material, and determine the preset opening of the air volume adjustment shutter. This is to automatically assist the artificial adjustment depending on the amount of culm supplied, and to adjust the air volume of the fan to an appropriate air volume to stabilize the sorting performance.
