摘要： PROBLEM TO BE SOLVED: To prevent that grains having small branches are charged into the first spiral and further charged into a grain tank without lowering a grading ability. SOLUTION: A diving plate 14 for obliquely dividing a vibration trellis 9 from a place at the front of the discharging port of a second grade-treating chamber to the transfer downstream side is disposed on a transfer trellis 9a. The dividing plate 14 surrounds and dams second grade products dropped from the second grain-treating chamber and divides so as to be mixed with threshed products dropped from a threshing chamber 2. The dividing plate divides the route for transferring the threshed products and second grade products into a threshed product transfer route A and a second product transfer route B. The bent portion (b) of a sieve 9b faced to the first spiral 11 of the second product transfer route B is higher than the bent portion (a) of a sieve at the other place.

摘要： PROBLEM TO BE SOLVED: To provide a controlling device for a secondary treatment capable of dissolving the problem of an inferior selection caused by the dropping of grains attached to insufficiently threshed branch and stem, since a conventional secondary treating chamber has a constitution for quickly treating the large amount of secondary product and discharging the same into a selecting chamber and, in many cases, the threshing treatment function thereof in the secondary treatment chamber is insufficient. SOLUTION: This controlling device for a secondary treatment in a threshing machine comprises a secondary treating chamber divided into plural treating chambers 7, 7' and 7" by partitioning plates, in which detecting means S1 , S2 for detecting the amount of the secondary material are installed for each partitioned chamber. The partitioning and guiding plates 6a, 6b are constituted by pivoting them to the lower part of the partitioning plate as adjustably inclined, being connected with actuators M1 , M2 for adjusting the control and capable of being exchanged to have the partitioning position or the guiding position. The controlling means connects the actuator M1 , M2 based on a detected information inputted from the detecting means S1 , S2 so as to output the controlling signal thereto, and outputs a control signal for adjusting the position of the partitioning and guiding plates 6a, 6b by inclining them to the guiding position.

摘要： PROBLEM TO BE SOLVED: To reduce an improper selecting operation by retarding control of a chaff sieve of an oscillating selecting rack in a threshing apparatus through an ON-delay to be set up according to operating conditions. SOLUTION: This apparatus has a grain-straw censoring means detecting the presence of reaped grain straws, a speed censoring means detecting a running speed of a body whether it is high or low and an oscillating selecting rack being made to be capable of regulating gaps among shutter-like blades of a chaff sieve selecting threshed objects. And this apparatus is equipped with a controller which sets up an ON-delay, making an output timing of an actuator increasing blade gaps on detecting a reaping state at high speed running of the body retard for a preferred passage of time, in such a way that the ON- delay tb in the case of detecting a speed change to high speed running in a reaping state at low speed running is lower than the ON-delay ta in the case of detecting start of reaping at high speed running.
