摘要： PROBLEM TO BE SOLVED: To safely operate a shift device even by an unfamiliarized person, by surely maintaining the transmission in a low speed condition when starting the engine of a machine body stopped for a long time, and eliminating malfuction such as starting the machine body at a high speed. SOLUTION: This device is equipped with gear type main and auxiliary transmissions 9 and 10 to be constituted so as to obtain a shift stage by combining both the transmissions, and also at least one of these transmissions 9 and 10 switches a solenoid valve by the command of a controller to actuate hydraulic actuators 33 and 34, so as to change a shift position. Turning a key switch ON commands a shift to the solenoid valve for changing the shift position to a first speed by the actuators 33 and 34. When a time measured by a timer is within a fixed time after stopping an engine, the shift position at that time is maintained.

摘要： PURPOSE:To facilitate turning operation on the edge of a ridge between rice fields by constituting height of a working machine raising and lowering link so as to become different when being put in a front and rear wheel opposite-phase steering mode in an automatic steering mode and when being restored to a front wheel steering mode from the opposite-phase steering mode. CONSTITUTION:When being put in a front wheel steering mode in an automatic steering mode, and when a lift cylinder 21 is operated and a connecting link 18 is raised, the height is detected by a sensor 84. When an angle theta of the connecting link exceeds theta1, a mode is switched to a front and rear wheel opposite-phase steering mode, and this becomes control when a operation lever is operated to the rising side to raise a working machine. After the working machine is raised and reaches prescribed height theta3, the working machine is lowered, and when the angle becomes smaller than prescribed theta2, the mode is restored to the front wheel steering mode. This becomes control when a machine body transfers to forward movement after turning is finished. In this way, when the working machine is lifted up, the mode is immediately put in the front and rear opposite-phase steering mode, and it turns at the minimum radius, and after the turning is finished, the working machine is transferred to the former front wheel steering mode when the working machine starts to be lowered.

摘要： PURPOSE:To improve selective operation efficiencies, by automatically adjusting the clearance between hulling rolls based on the result of compatative operation between a measured hulling rate and set hulling rate, thereby automatically adjusting the clearance to a roll clearance corresponding to the efficiency when the operation efficiency is changed. CONSTITUTION:A part of mixed rice introduced as sample grains is detected by means of a unhulled rice-rice judging sensor 19, whereby a CPU 30 having received the judgement informations judges the difference between unhulled rice and unmilled rice and stores them to compute a hulling rate, wherein measured hulling rates and hulling rate having been set beforehand are computed in comparison with each other, in response to the result of which actuation command signals are outputted to a positive rotation circuit 33 or to a reverse rotation circuit 34 so that the clearance between rolls is automatically controlled to achieve a desired hulling rate. During such controlled operation, the CPU 30 reads a change in the position of a milled rice adjustment valve to deliver an actuation command signal to a proper circuit, the positive circuit 33 or reverse rotation circuit 34, when it has judged the occurrence of change, thereby adjusting automatically the roll clearance in response to a variation in the operation.

摘要： PURPOSE:To perform crushing of grains under test accurately, by forming irregular surfaces on the outer surfaces of electrode rolls, and forming deep grooves along the direction of the rotary axes of the rolls on the outer surfaces. CONSTITUTION:During the measuring operation of moisture, a grain under test from a one-grain feeding device 20 reaches an upper space, which is formed with a pair of electrode rolls 21 and 21. Irregularities are formed on the surfaces of the rolls 21 and 21 so that engagement with the grain under test is excellent. The rolls 21 and 21 are rotated at the different circumferential speeds, and the grain under test is crushed. Thus an electric resistance value is obtained. When the long grain under test having a large diameter is supplied on the rolls 21 and 21, the grain is not engaged with only such irregularities and tend to remain in the V space formed with both rolls 21 and 21. However, deep grooves are formed on the surfaces. The grain under test in the horizontally fallen-down state is liable to be engaged with the acute parts of the deep grooves on the side of the outer surfaces of the rolls 21. The grain is turned with the rotation of the roll 21 and crushed between the roll and the other roll 21.

摘要： PURPOSE:To securely feed out one grain by providing a guide body with a wall part which is high enough to couple and hole a single grain between a spiral groove. CONSTITUTION:A one-grain feeding-out device 5 consists of a feed roller 10, the plate type guide body 12 which contacts the roll 10 slantingly in a peripheral surface tangential direction, etc., and the spirals groove 13 where one grain is coupled is formed in the peripherals surface of the roll 10 to the overall axial length. At the time of a driving signal is supplied to a motor 19 during drying operation, the motor 19 rotates to rotate the roll 10 and an electrode roll 6, and grains supplied from an elevator are received by the conveyance start end side of the guide body 12. At the time of the roll 10 is rotated, grains coupled in the groove 13 are held by the wall part of the guide plate part 16 and fed, grain by grain, in the axial direction. Even if plural grains are being accumulated in the groove 13, they slides out of the groove 13 and are discharged downward through a cut part 15 as they are because there is not the wall part of the guide plate part 16 to be held in the groove 13 in the coupling state. One grain held by the groove 13 of the roll 10 and the wall part of the guide plate 16 is guided 28 and crushed 6, and its water value is found.
