摘要： PURPOSE: To provide a pretreating apparatus for reaping in a whole-culm charging-type combine having little trouble of recovery loss and carrying in soil and excellent in operability and handleability by enabling the shift of the transfer-bottom board of a feed conveyor between a blind state and a perforated state and the optimization of the hole size in the perforated state depending on the harvest object. CONSTITUTION: In this pretreating apparatus for reaping, a transfer-bottom board 10 of a feed conveyor 7 is composed of a pair of perforated boards 10a, 10b one on the top of the other. One 10b of the boards is constructed in a state to be slidable and fixable freely along the layering surface against the other board 10a. Thus, the transfer-bottom board 10 is shiftable between a blind state and a perforated state. Further it is preferable that a transfer-bottom board 9 of an auger 8 is composed of a pair of perforated boards 9a, 9b one on the top of the other, and one 9b of the perforated boards is made to be slidable and fixable freely along the layering surface against the other board 9a so that the transfer-bottom board 9 is shiftable between a blind state and a perforated state.

摘要： PURPOSE:To provide a combine harvester capable of surely grading treating materials with a grading wind around the front part of a chaff sieve on which a large quantity of the treating materials are dropped, simultaneously improving the dust-discharging performance at the rear end of a grading section, and capable of compacting a threshing device. CONSTITUTION:The vibration-grading section 7 of a threshing device 2 in a combine harvester is manufactured by disposing a roughly grading section 20 and a precisely grading section 21 and further forming an opening 22 capable of introducing a part of a grading wind into a space between the roughly grading section 20 and the precisely grading section 21 in a vibration-grading case 12. A counter shaft 23 rotation-driven with an engine disposed on the lateral side of the threshing device 2 is disposed on the route of the grading wind from a winnower 13 at a place front from the opening 22 of the vibration- grading case 12 so as to cross the wind route. A cover 24 for covering the counter shaft 23 is laterally suspended and fixed, and the cross section of the cover 24 is formed in a shape capable of guiding a part of the grading wind introduced into the opening 22 into the front part of the chaff sieve 19.
