To provide a threshing apparatus supplementing the winnowing capacity of a winnower fan and improving the winnowing capacity of tailings to improve the recovering efficiency of grains with reduced cost.
Tailings comprising relatively small-size treating objects among treating objects falling from a threshing chamber 66 and a tailings treating chamber 67 placed adjacent to the threshing chamber 66 to a shaking shelf 51 of a screening chamber 50 are transferred toward the tailings treating chamber 67 with a tailing screw 86 placed in the cavity of the tailing shelf 85 while blowing screening wind from an opening 93 opened on the sidewall of the threshing apparatus 15 by a fan 90 placed on the extended part of a driving shaft 86a of the tailing screw 86 and blowing screening wind from the lower end of the tailing screw 86 toward the upper part of the tailing screw 86, thereby inhibiting the transfer of the straw dust, etc., in the tailings into the tailings treating chamber 67 to improve the screening performance of the tailings, dispense with an exclusive transmission mechanism for the fan 90 and reduce the cost of the fan 90 and the installation cost of the apparatus.
