Field of the Invention The present invention relates to a shutter provided at a supply port at a lower portion of a storage tank, a shutter arm having an upper end pivotally attached to a support attached to a lower side of the storage tank, and a set amount of a weighing scale. A reciprocating member that operates via a solenoid by measuring the amount of the reciprocating member. The reciprocating member is connected to a shutter arm, and the shutter arm is retracted with its upper end serving as a fulcrum. The present invention relates to a shutter operating device of an automatic grain weighing machine that switches the supply port between full open, partial open, and full close by disengagement / engagement.

[0002]

2. Description of the Related Art As described above, a reciprocating member operating via a solenoid by measuring a set amount of a weighing scale is connected to a shutter arm, and the shutter arm is retracted with its upper end serving as a fulcrum. The applicant has developed and prototyped a shutter operating device for an automatic grain weighing machine that switches the supply port between full open, partial open and full close by disengagement / engagement of a shutter and a shutter. In the prior art configuration including this prototype, the shutter is partially opened and fully closed via the solenoid by weighing the set amount of the weighing scale at the time of weighing. When the operation is interrupted, a mechanism for arbitrarily closing the shutter is not provided, so that the shutter may be left open after the weighing operation.

[0003]

As described above, in the prior art arrangements including the ones developed and prototyped last time, a mechanism for arbitrarily closing the shutter when the weighing operation is completed or interrupted is not provided. Therefore, the shutter may be left open after the weighing operation, so that there is a drawback that the mouse enters or that the liquid remaining in the storage tank at the start of the operation is scattered from the supply port. Accordingly, the present invention has been made to solve these disadvantages and to provide a shutter operating device of an automatic grain weighing machine which can fully close the shutter arbitrarily after or during the weighing operation.

[0004]

Therefore, according to the present invention, means for solving the problems described in the preceding section will be described below. A shutter pivotally connected to a supply port at the lower part of the storage tank, a shutter arm pivotally connected to an upper end at a support attached to the lower side of the storage tank, and a reciprocating mechanism operated via a solenoid by measuring a set amount of a weighing scale. The reciprocating member is connected to a shutter arm, and the shutter arm is retracted with its upper end at a fulcrum, and the supply port is fully opened and partially opened by disengagement / engagement of the shutter arm and the shutter. In a shutter operating device that switches between open and fully closed, two systems are provided, a path for automatically energizing the solenoid energizing path by weighing the weighing scale and a path for manually energizing via a main power supply and a power switch. Accordingly, the shutter can be closed by a manual operation via a solenoid.

[0005] The manual operation will be described. In the shutter operating device described in the preceding paragraph, the main power supply and the power switch are provided, and when the power switch is turned off, the power of the operation panel is turned off, and at the same time, the solenoid is energized. When the main power is turned off, the solenoid is turned off. Turn off the power switch provided on the operation panel when the weighing operation is completed or the operation is interrupted when there is no kernel in the storage tank during the weighing operation by configuring so that the electricity can be released. Then, the solenoid is energized, the shutter arm retreats via the reciprocating member, separates from the shutter, releases the holding of the open state, and the shutter fully closes the supply port. Thereafter, when the main power supply is turned "OFF", the reciprocating member is moved back and the shutter arm is also moved back, so that the fully opened state can be reproduced by manual operation.
