摘要： PROBLEM TO BE SOLVED: To provide sieve case structure for thresher with which the aperture of chaff sieve can be automatically adjusted corresponding to the amount of objects to be processed on a chaff sieve while attaining the reduction of production costs and accuracy in sorting can be improved. SOLUTION: Concerning the sieve case structure for thresher, the chaff sieve is constituted so as to adjust its aperture by linking the group of chaff lip plates 16A for the chaff sieve mounted in a sieve case so as to freely swing while being interlocked around lateral supporting points P3 set to respective upper ends. Then, an energizing means Z is provided for elastically energizing this chaff sieve on the side of close so as to change the aperture of chaff sieve corresponding to the weight of processing objects to be operated upon this chaff sieve, and the energizing force of energizing means Z with the critical minimum aperture of chaff sieve can be changed in setting.

摘要： PROBLEM TO BE SOLVED: To provide the chaff sieve structure of a grain sorting device capable of excellently performing leak-down sorting even when the presence/absence state of processing objects on a chaff sieve is not uniform and partially localized. SOLUTION: Many chaff plates 13 are horizontally disposed to a swing sorting frame 8 in the state of being arranged side by side with intervals at the front and back, the respective chaff plates 13 are respectively independently and freely swingably supported and constituted freely openably and closably corresponding to the fluctuation of processing object loads so as to enlarge an opening degree when the loads of the processing objects on the respective chaff plates 13 are enlarged and a flow rate detection means 20 for detecting a threshing flow rate is provided. Further, a minimum opening degree to be a reference in the opening/closing swing of the respective chaff plates 13 is made freely changeable so as to be enlarged as the flow rate is enlarged based on a detected flow rate by the flow rate detection means 20.

摘要： PURPOSE: To provide a chaff sieve structure in a thresher capable of suppressing the stagnation and obstruction, and having improved conveying properties and sorting efficiencies by arranging both right and left ends of a chaff plate as inclined based on the longitudinal direction so as to convey the disposing material aslant from left and right sides to the middle of the chaff sieve. CONSTITUTION: This chaff sieve structure in a thresher is obtained by providing a chaff sieve 14 by installing the multiple number of chaff plates 14a in the longitudinal direction in parallel in the state of conveying the disposing material for sorting in the direction of the center of the shaft of a treating drum, forming the chaff plates 14a inclined by a plane view in the longitudinal direction, and arranging both left and right ends of the chaff plates 14a as inclined based on the longitudinal direction so as to convey the disposing material aslant from left and right sides to the middle of the chaff sieve 14.

摘要： PURPOSE: To provide a structure for a grading part of a thresher capable of smoothly carrying out the grading treatment of treated materials even when the amount of the threshed materials is large or the wet threshing treatment is performed and miniaturizing a grader. CONSTITUTION: This structure for a grading part of a thresher is obtained by installing a grain sieve 13 for cleaning and grading under a chaff sieve 6 for roughly grading treated materials leaked down from a receiving net 4 of a threshing chamber with a prescribed interval separated from the chaff sieve 6 and further arranging a grain pan 14 for moving the leaked down treated materials from the chaff sieve 13 to the rear while grading the leaked treated materials by specific gravity, arranging plural sieving wires 15, extended from the rear end of the grain pan 14 to the rear and used for loosening the treated materials in a state thereof installed side by side left and right and locating the rear ends of the sieving wires 15 on the middle of the grain sieve 13 in the front and rear directions.
