Description

  The present invention relates to an agitation device for a cereal tank that agitates grains stored in a cereal tank such as an outdoor-type grain drying storage in the cereal tank vertically and horizontally.

  As an agitation device for a cereal tank, a device in which a bearing pulley and a transmission pulley for receiving power transmission are mounted on the upper end of an auger shaft of the agitation device is usually used. This agitation device of the cereal agitates the grains in the vicinity of the auger shaft in the cereal tank up and down and left and right by the rotation of the auger shaft, and evenly agitates all the grains in the cereal by revolving or moving back and forth of the agitation device itself. Is.

  In the auger shaft of an agitator equipped with one of the bearing support and the power transmission pulley at the upper end of the auger shaft, the auger shaft itself retreats due to the revolution of the guide boom or the pressure received from the grain as the auger shaft moves in the front-rear direction. Often swings and tilts.

  In Patent Document 1, bearing support portions for an auger shaft are provided above and below a support machine frame assembled and supported on a guide boom, and a power transmission pulley is disposed at the upper end of the auger shaft that penetrates the support machine frame. Is connected to the motor by a transmission belt, and the rotation of the motor agitates the grain up and down. The cylindrical guide boom and the support machine frame are guided by the agitator itself by the rotation of the bearing and the guide boom. Since it is connected with a drive roll attached with an inclination angle so as to move back and forth in the boom, the auger shaft spreads all over the grain tank by the revolution and rotation of the guide boom, so that the grain is stirred up and down and left and right It has become.

In addition, since the cylindrical guide boom and the support machine frame of the stirring device are connected only by the bearing and the drive roll, the auger shaft follows the movement of the lower end side with some delay due to the resistance of the grain due to the revolution of the guide boom. also, the auger shaft itself is inclined with the support machine frame of the stirring device, and relaxed to undergo stress auger shaft itself bends.

  Further, as in Patent Document 2, a traveling body that is reciprocally driven along a longitudinal direction of a pair of side portions is provided at a location on the upper side of the storage space having a short side shape in plan view, and is orthogonal to the traveling body.

  In Patent Document 1, the lower end of the auger shaft is subjected to the resistance of the hook against the revolution of the guide boom, and the inclination of the auger shaft generated by following the delay is caused by the support machine frame and the auger shaft, that is, the agitator itself. Since the guide boom is tilted around the fulcrum, the bending stress applied to the auger shaft is reduced.

  As described above, in Patent Document 1, the stirring device itself is inclined only to the revolving direction of the guide boom, even if the auger shaft has an inclination angle, and has a structure that alleviates the bending stress of the auger shaft. The contact point between the frame and the cylindrical guide boom is a bearing and a drive roll, and the support machine frames are connected to each other by a connecting rod. The bending stress of the added grain resistance is received without relaxation.

  Also in Patent Document 2, the tilt sensor has a structure that allows the tilt amount to be detected and the auger shaft to be tilted because the main traveling body that is driven to reciprocate along the longitudinal direction of a pair of opposing sides. In an auxiliary traveling body provided in a moving direction and capable of reciprocating driving along a direction perpendicular to the main traveling body, a device for detecting the amount of inclination and a mechanism for enabling slight inclination of the auger shaft are provided. Not.

  In Patent Documents 1 and 2, a method of avoiding the movement of one stirring device even if the auger shaft is inclined by the pressure of the grain is taken. There is no way to avoid a certain force of the grain that is received, and there is a possibility that an inevitable inclination that cannot be avoided even in the direction of avoidance may cause the auger shaft to be deformed or broken. Cannot be denied.

There is no method for knowing deformation, and the auger shaft is long and heavy, and the auger shaft is also equipped with a shaft support and a driving pulley. machine carrying the working of the auger shaft to be newly exchanged, must assemble the shaft support portion and drive pulley above the auger shaft, the replacement of the auger shaft and required a lot of time and manpower.

  Accordingly, the present invention is intended to solve the above-described problems, and is configured so that the auger shaft can be disassembled into a plurality of parts, and a part of the auger shaft in which a defect such as deformation or cutting has occurred is replaced. It is an object of the present invention to provide a stirring device for a cereal basin that recovers its function and facilitates an auger shaft replacement operation.

The stirring device of the cereal basin according to claim 1 according to the present invention supports a guide boom that revolves around a substantially axial center portion of the basin on a ceiling portion in the cereal basin such as an outdoor type grain drying storage, The guide boom is equipped with a turning drive device for revolving the inside of the basin and a support machine frame having an auger shaft that is fixed to the guide boom or reciprocates freely between the inner end and the outer end of the guide boom. In the grain agitating apparatus, the auger shaft provided in the support machine frame can be divided, and when the auger shaft is assembled or removed, a hook part for hooking the auger shaft and a support machine frame are supported. A suspension device comprising an attachment portion, an elevating shaft for slidably attaching the hook portion to the attachment portion, and a handle shaft capable of changing the distance between the attachment portion and the hook portion by rotating. And even It is.

According to the present invention, a portion (particularly near the lower bearing support portion (bearing)) where bending stress is likely to occur is divided, so that the auger shaft is cut and deformed due to unpredictable stress. Since only that part can be replaced, the replacement work can be performed easily. Since the auger shaft has been divided and the suspension system can be used for replacement work, replacement of the auger shaft has so far required many personnel, but one worker can do this. , Can greatly improve the work efficiency.
