Description

[Detailed Description of the Invention] The present invention relates to an automatic stop device in a stirring device for a paddy storage room.

In other words, a transverse feed shaft extending radially from the center of the storage chamber is installed so that it can be freely driven by both motors, so that it revolves around the center and rotates on its own axis. In an agitation device for a paddy storage room, in which a screw is freely rotatable and a plurality of agitators are reciprocably installed, each of which is vertically installed below each agitator, the paddy in the room is If the hanging screw tilts in the forward direction due to the load of paddy while stirring, the lateral and forward movement of the stirrer can be automatically stopped to prevent poor stirring. The present invention provides a simple structure in which the inclination of the screw can be reliably detected by rotation of a limit switch using a balance weight, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a cross-sectional view of a storage room. This storage room A can store paddy 4 and dry it at room temperature. A support frame 5 is suspended from the ceiling at the center above the storage room A. At the same time, a support body 6 is rotatably installed at the lower part of the support frame 5, and the support body 6 rotatably supports an end of a transverse feed shaft 1 extending horizontally in the radial direction. The waist support 6 is installed so that the transverse feed shaft 1 can revolve around the center of the support frame 6 as the center O.
The cross-feeding shaft 1 is rotatably installed so that it rotates on its own axis via the transmission part 7 by a motor M2 installed in the lateral-feeding shaft 1. A long screw 2 is installed vertically below the agitator B' which is loosely fitted to the tip side of the transverse feed shaft 1, and a motor M1 attached to the agitator B' The support wheel 8 is installed so that it can be driven through the transmission part 10, and when the waist support wheel 8 rolls along the rail 9, the transverse feed shaft 1 is installed so that it can revolve around the center O. Construct in the same way as the shape structure.

In addition, a plurality of stirrers B are installed at intervals on the horizontal feed shaft 1, and each stirrer B has a long screw attached to the front lower part of the container body that is slidably fitted on the horizontal feed shaft 1. A belt 13 is hung between the pulley 11 of the motor M3 attached to the rear of the machine body and the pulley 12 at the upper end of the shaft 2a of the screw 2. Both bearings 14.14 are installed in the upper two places of 1, and the lower part 1
Bearings 14 are connected to these positions, as shown in FIG. 6, so that the respective axes are inclined with respect to the axis of the cross-feeding shaft 1, and when the cross-feeding shaft 1 rotates due to the inclination of the bearings 14. The container is installed so that it moves in the axial direction, and when the motor M2 is reversed by the timer operation, the container moves in the opposite direction, so that, for example, the container makes one reciprocation every four hours. The structure is the same as the conventional structure.

Note that the agitator B' is constructed almost the same as the agitator B, but the bearing 14' of the agitator B' is not inclined in the axial direction, so that the agitator B' reciprocates in the axial direction. The structure is such that it does not.

For agitator B, attach the mounting bracket 1 from the bottom of one side of the vessel.
5 is vertically installed, and both sides of the mounting bracket 15 are bent in the same direction to make the refracting pieces 15a, 15a stand up. A limit switch S that can be rotated around the limit switch 16 and is in a hanging state is installed, and the lower part of the lever 17 that hangs down together with the limit switch S is attached to a balance weight 3 made of a long bar of about 100 grams, for example. Insert into the top and screw 1
8, and when the screw 2 is in the vertical position, the limit switch S will hang down due to the gravity of the balance weight 3 and turn off. When the body is in a rotating state, the limit switch S is turned on by the balance weight 3, and the motors M1 and M2 are stopped by turning on the limit switch S.
The limit switch S is installed and configured so that when the screw 2 becomes vertical, the limit switch S is turned off again.

Therefore, the screws 2 of each of the agitators B and B' plunge deeply into the paddy 4 in the storage room A in a vertical state due to their own weight, and the support wheels 8 are rotated on the rails 9 by the start of the motor M1. The transverse feed shaft 1 revolves around the center O as shown by arrow A, and when the motor M2 is started, the transverse feed shaft 1 is rotated forward and backward at regular intervals, and the agitator B is rotated by the inclined joint of the bearing 14. , B will reciprocate in the axial direction as shown by the arrowhead, and each stirrer B.

The screws 2 in B and B' are the respective motors M
3, it is driven and rotated.

Therefore, by the rotation of each screw 2, the paddy 4 can be stirred while moving in the vertical direction, and each screw 2
While moving forward in the direction of arrow A while remaining in a vertical position, it reciprocates in the lateral direction as shown by the arrow opening, so that the paddy 4 being dried at room temperature can be thoroughly stirred.

By the way, when the screw 2 is moving forward and tilts so that the lower part is backward with respect to the forward direction C due to the resistance of the paddy 4, the vessel body rotates with respect to the transverse feed shaft 1, and the balance is changed. Limit switch S due to the gravity of weight 3
rotates around the spindle 16. Then, the limit switch S is turned on, motors M1 and M2 stop, and the screw 2
Although it is rotating, it does not move in the forward direction C or in the lateral direction, and poor stirring by the inclined screw 2 is prevented.

From this state, when the rotating screw 2 returns to the vertical state due to its own weight, the rotation causes the limit switch S to turn to its original state and turn off, and the motors Ml and M2 are turned off again.
will start and move forward and sideways.

In this way, the present invention has a balance weight suspended from a rotatable limit switch attached to each stirrer, and the limit switch is rotated by the balance weight as the screw tilts beyond a certain level with respect to the forward direction. Since the connection is made so that both the revolution and rotation motors of the transverse feed shaft can be stopped when the motor is turned on, the screws in the hanging state move in the forward direction while the screws of each agitator are stirring the paddy in the room. On the other hand, when the screw tilts due to the load of paddy, the limit switch also changes its tilt and immediately stops the motor while automatically stopping lateral and forward movement to reliably prevent poor stirring. The tilt can be reliably detected and activated by rotating the limit switch using a balance weight, and it has a feature that it can be suitably implemented with a simple structure.
