摘要： PURPOSE:To prevent a load from concentrating in the former half part of a threshing drum when the amount of grain culms fed into a threshing chamber is especially increased in a thresher. CONSTITUTION:A threshing drum structure is equipped with threshing teeth 21, made of a nylon rope and capable of elastically performing the retreat and displacement in the direction opposite the rotational direction of a threshing drum 2 by a higher load than the set value in a part on the side of an inlet 6 of the threshing chamber 1 in the threshing drum 2. Thereby, concentration of a load in the former half part of the threshing drum 2 is prevented to disperse the load in the latter half part of the threshing drum 2.

摘要： PURPOSE:To expand the processable range of threshing work by placing a threshing drum in a threshing chamber in a state freely drivable and rotatable on a longitudinal shaft, placing a screening part under the threshing chamber and placing an assistant threshing drum in front of the threshing chamber in a state drivable and rotatable on a longitudinal shaft. CONSTITUTION:A threshing drum 4 is placed in a threshing chamber 3 in a state drivable and rotatable on a longitudinal shaft, a screening part is placed under the threshing chamber and an assistant threshing drum 12 is placed in front of the threshing chamber. The threshing capacity can be increased without expanding the diameter of the threshing drum or increasing the rotational speed of the drum.

摘要： PURPOSE:To enable sufficient grading treatment near a grain pan and a grain sieve when the through-put is especially increased in a thresher constructed so as to enable the operation to change the grain sieve to a large and a small areas by carrying out the operation to slide the grain pan. CONSTITUTION:This thresher is obtained by installing a wind rectifying guide member 22 enabling the free changeover between the first state in which a part of a grading wind from a fan mill 8 is made to flow in an oblique upward direction onto a grain pan 18 and the second state in which the grading wind at a lower flow rate than that of the first state is made to flow at a gentle angle onto the grain pan 18 and linking the grain pan 18 to the wind rectifying guide member 22 so as to make the wind rectifying guide member perform the operation of changeover between the first state side interlocking with the operation to slide the grain pan 18 to the increasing side of the area of a grain sieve 19 and the second state side interlocking with the operation to slide the grain pan 18 to the reducing side of the area of the grain sieve 19.

摘要： PURPOSE:To eliminate the trouble in which the amount of materials to be treated in a rocking and grading case is excess due to a little clogged state of a treating and rotating body part and the expected improvement in the grading ability is not exhibited. CONSTITUTION:In a thresher equipped with a treating and rotating body 6, capable of applying loosening action to materials which are conveyed with an upper straw rack 18 rocking with a rocking and grading case 5 and treated at a position just after a dust feed port (2a), plural treating teeth (6C) are attached to a screw belt (6B), wound and installed on the outer periphery of a treating drum (6A) at an interval of a constant angle to construct the treating and rotating body 6. The direction of the screw belt (6B) is subsequently set so as to transversely transfer the materials which are to be treated and subjected to the loosening force of the treating and rotating body 6 to the side of a feed chain 4. Thereby, the material which are to be treated and deviated to the side opposite the feed chain 4 are dispersed in the transverse direction and readily loosened.

摘要： PURPOSE:To properly select threshing and selection by automatically controlling a selection state based on detected information of recognized information of recovered amount detecting means. CONSTITUTION:A selector to select a treated material from a handling chamber is provided with a control means 43 to automatically operate actuators M1 and M2 for winnower to regulate a selecting state of the selector in such a way that the selecting state is adjustable depending upon the amount to be treated and the selecting state is made into a selecting state suitable for the increased amount to be treated as the amount to be treated is increased. Then a recovered amount detecting means 32 discovers a recovered amount of grain granule selected and recovered by the selector per unit time. Further a control means 43 adjusts the selector to a selecting state corresponding to the increased amount as the recovered amount per unit time is enlarged based on information of the recovered amount detecting means 32. Consequently, proper threshing and selecting control can be carried out.

CONSTITUTION:A thresher 2 has a dust feeding port 19 opened at the back of as threshing chamber (A) and the following construction is added thereto. That is a sensing means (S1) for the amount of fed grain culms for sensing the amount of the grain culms fed to the threshing chamber (A) is provided and an opening degree changing means (K) for changing the opening degree of the dust feeding port 19 is simultaneously provided. A controlling means for automatically regulating the opening degree changing means (K) so as to increase the opening degree of the dust feeding port 19 with increasing amount of fed grain culms based on the sensed information from the sensing means (S1) for the amount of the fed grain culms is also installed.

摘要： PURPOSE: To provide a structure for a grading part of a thresher capable of smoothly and thoroughly performing the movement and grading of treated materials in a rough grading passage part even if the amount of the threshing treated materials is large. CONSTITUTION: This structure for a grading part of a thresher is obtained by installing a grain pan 8 for transferring materials discharged from a dust feeding port 7 at the rear end of a threshing chamber to the rear while grading the materials with specific gravity and further providing a rough grading passage part 6 for transferring the leaked down treated materials from a receiving net 4 in the threshing chamber to the rear while roughly grading the leaked down treated materials within a range extending from the lower part of the receiving net 4 to the lower part of the grain pan 8. The plane of action of the grain pan 8 is constituted as a forwardly rising slope.

摘要： PURPOSE:To provide a sieve case-driving part designed to improve the durability of a bearing part in between a sieve case and a crank arm by swingingly driving the sieve case smoothly through the straddle-mounted crank arm. CONSTITUTION:A crank arm 20 having support shafts 20a at both ends, arm parts 20b connected respectively to the support shafts 20a, and a rod 20c connected these arms parts 20b to each other is formed rotatably under driving, and a bearing is placed in between the rod 20c and a bearing bracket 23 mounted on a sieve case 17. In this sieve case-driving part in a thresher, both the arm parts 20b and the rod 20c are made to stand separate from each other, and a rolling bearing 26 is equipped in between the bearing bracket 23 and the rod 20c.
