Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a livestock manure processing apparatus having turntables arranged at both ends of a pit and configured to change the direction of an agitator by rotation of the turntable. The present invention relates to a turning device for a stirrer in a livestock manure processing device, which prevents inertial rotation of a turntable at the time of turning the stirrer so that the wheel and rail of the stirrer are not caught and the direction can be surely changed.

[Conventional technology]

By using a turntable, the basic structure of a livestock manure processing device which is continuously operated by changing the direction without stopping the agitator at both corners of the pit is disclosed in JP-A-59-396. In addition, "While the wheels of the stirrer are mounted on the rails laid on the upper end surfaces of the track-shaped peripheral wall forming the pit and the central linear partition wall, and the partition wall at the bottom of the pit is mounted. Fixed cylindrical cylinders are erected on the extension lines of both ends, and a rotating cylindrical cylinder fixed to the lower surface of the turntable is rotatably fitted to the outside of the fixed cylindrical cylinder and laid on the upper end of the partition wall. A rail having the same cross-sectional shape as that of the pit is laid on the turntable, and the wheels inside the agitator are placed on the turntable. Those diverting "the the stirring agitator in part.

In the above-mentioned type of livestock manure processing device, the direction of the pit must be changed without stopping the agitator at both corners of the pit.

Since livestock manure is stored in the pit and the lower half of the direction changing device composed of the turntable is buried in the livestock manure, it is complicated to accurately control the rotation stop position of the turntable. It is difficult to expose the stopper device having the structure to the outside.

However, in order to smoothly change the direction of the stirrer without stopping its traveling, when the wheels inside the stirrer transfer between the rail laid on the turntable and the rail laid on the partition wall, Wheels must be prevented from getting caught on the rails or coming off.

However, when the stirrer turns around at both ends of the pit, the weight of the stirrer is large, so that even if the rotation speed is low, the inertia is large and the rotating part that constitutes the turning device of the stirrer is Since the rotation resistance of the non-rotating portion is supported by the bearing and the rotation resistance of the non-rotating portion is small, even if the rotation of the wheels on the outside of the stirrer is stopped, the stirrer continues to rotate in that direction due to inertia.

As a result, when the turntable stops rotating, the rails laid on the turntable and the rails laid on the partition walls are inconsistent, and the wheels inside the stirrer move from the rails laid on the turntable when turning. There was a problem that the rails laid on the partition wall could not be transferred smoothly or the wheels could be derailed.

[Problems to be solved by the invention]

In view of the above-mentioned problems, the present invention prevents the turntable from inertial rotation without providing a complicated stopper device in the direction changing device including the turntable, and thus the agitator at both corners of the pit. It was made with the purpose of making it possible to smoothly turn around.

[Means for solving problems]

Means adopted by the present invention to solve the above-mentioned problems are, in the above-mentioned livestock manure processing apparatus, a rotary cylindrical body fixed to the lower surface of the turntable and a fixed cylindrical body standing on the bottom of the pit. That is, a resistor is slidably attached to the outer peripheral surface.

[Function of device]

Since the rotary cylinder body rotates while the resistor mounted on the rotary cylinder body fixed to the lower surface of the turntable slides on the outer peripheral surface of the fixed cylinder body, the rotation resistance of the turntable increases. The inertial rotation at the time of stop of is reliably prevented. Therefore, after the turntable is rotated, there is no discrepancy between the rail laid on the turntable and the rail laid on the partition wall of the pit, and the direction of the stirrer is smoothly changed.

Fixed cylindrical barrels 17 are erected on the extension lines of both ends of the partition wall 5 on the concrete base 1 at the bottom of the straight pit 6, and turntables 18 are mounted on the fixed cylindrical barrels 17 so as to rotate in a horizontal plane. There is. A rotary support shaft 19 and a rotary cylindrical body 20 are attached to the lower surface of the turntable 18. The rotary support shaft 19 is supported by a radial bearing 21 and a thrust bearing 22 mounted on the fixed cylindrical barrel 17, thereby coping with the force applied in the radial direction and the axial direction of the support shaft 19.

The rotary cylinder body 20 attached to the lower surface of the turntable 18 is fitted into the upper end portion of the fixed cylinder body 17 via a lining material 23. This lining material 23 is a turntable 18

The stirrer A runs in the direction of the arrow P in the straight pit 6, and the inner wheel 12 fitted on the rail 9 turns the turntable.
When the rail 28 laid on 18 is completely transferred, the limit switch S attached to the agitator A is actuated by the dog D ₁ , the motor M ₂ that drives and rotates the inner wheel 12 is stopped, and the wheel 12 is moved to the rail. Will remain stopped above 28.

However, since the outer wheels 11 continue to be driven and rotated, the agitator A rotates around the rotation support shaft 19 of the turntable 18 in the corner pit 7 in the direction of arrow Q.

When the turntable 18 rotates half a turn, the limit switch S attached to the stirrer A is actuated by the dog D ₂ , the drive motor M ₂ is restarted, and the inner wheel 12 fitted to the rail 28 is driven to rotate. First, the inner wheel 12 is transferred from the rail 28 laid on the turntable 18 to the rail 9 laid on the partition wall 5 in the opposite manner to the above, and the agitator A travels in the linear pit 6 in the direction of arrow R.

The turntable 18 is prevented from inertial rotation when the rotation of 18 is stopped. Therefore, when the turntable 18 is stopped, the rails 28 laid on the turntable 18 and the rails 9 laid on the partition wall 5 are located on substantially the same straight line without any discrepancy. When the wheel 12 moves between the two rails 9 and 28, it is possible to prevent the wheel 12 from being caught by the rails 9 and 28 and stopping the traveling, or in the extreme case, being derailed. can do.

In addition, with the adjusting bolt 27, a resistor for the fixed cylindrical body 17
