ータ１７が破損する恐れがある。During operation, the cylindrical screen 3 and the main shaft 6 are rotated in the same direction 20 by driving the motor 17. Since the rotational speed of the main shaft 6 is selected to be larger than the rotational speed of the cylindrical screen 3, the scraping plate 5 will collide with the protrusion 4 by pinching the dust during the crushing operation. A rotational force is applied to the screen 3, and the torque transmitted to the cylindrical screen 3 by this 25 is transmitted through the drive system of the cylindrical screen 3, reaches the pulley shaft 24, and is transmitted again to the drive system of the main shaft 6. Therefore, motor 1? This means that only the difference in torque between the two drive systems needs to be borne. 30 However, at the time of starting the device, the cylindrical screen 3 has a large inertia, and an excessive load is applied to the motor IT. If there is only enough capacity to bear the burden, there is a risk that an overcurrent will flow 35 and damage the motor 17.

、従来のものより小容量のものとすることができる。Motor 1? In order to prevent damage to the cylindrical screen 3, it is necessary to increase the capacity or use a shock absorbing joint or the like in the drive system of the cylindrical screen 3, which has a shock absorbing effect at the time of startup. Increasing the capacity of the motor 17 eliminates the advantage of driving both the cylindrical screen 3 and the main shaft 6 drive system with one motor, so conventionally the clutch 22 was used to absorb the shock at startup. . However, the clutch 22 has a disadvantage in that its shock absorbing effect is weak and the friction plates are frequently worn, requiring frequent replacement. Therefore, if a fluid coupling or a powder coupling is used instead of the clutch 22, the buffering effect will be increased, the motor 17 will start smoothly, and the shock during operation will be absorbed, so the load on the motor 17 will be reduced. It can have a smaller capacity than the conventional one.

ことを目的とするものである。However, if something that cannot be crushed, such as a stone or a metal lump, gets caught between the protrusion 4 and the scraper plate 5 during operation, the cylindrical screen 3 will be pushed by the scraper plate 5 and a large torque will be applied. is added to the drive system of the cylindrical screen 3. If the belt 23 slips or breaks due to this abnormal torque, it will be able to rotate due to the force of the buffer joint, which is a fluid joint or a powder joint, and will be rotated from the cylindrical screen 3 on the load side, causing an abnormality. The product may rotate at such high speed that it exceeds the allowable rotation speed and may be destroyed by centrifugal force. Conventionally, in such cases, a method has been adopted in which the torque detector 21 detects the abnormal torque and controls the drive mechanism to reduce the torque, but electrical safety devices cannot sufficiently prevent danger. , which lacked safety. SUMMARY OF THE INVENTION An object of the present invention is to provide a drive device for a crushing and sorting machine that is sufficiently safe even when unshredable materials are caught, while eliminating the above-mentioned drawbacks of the conventional devices.

ある。The present invention rotatably supports a cylindrical screen having a supply port and a discharge port and a projection on the inner circumferential surface, rotatably supports a main shaft provided with a scraper inside the cylindrical screen, and The outer circumference of the scraping plate is selected to be smaller than the inner circumference of the protrusion,
In the drive device for a crushing and sorting machine, the drive device includes a drive device that has a gap during relative rotation and causes the cylindrical screen and the main shaft to be rotated in the same direction by the same prime mover, wherein the prime mover is a double-shaft type, The cylindrical screen is driven by one shaft, the main shaft is driven by the other shaft, and the shaft that drives the cylindrical screen is directly connected with a buffer joint for mitigating rotational impact force. This is the machine's drive device.

ている。The motor 17 is of a double-shaft type, with one shaft driving the main shaft 6 and the other shaft driving the cylindrical screen 3.

いう事故は起こらない。That is, the drive system for the main shaft 6 and the drive system for the cylindrical screen 3 are separated. A buffer joint 32 is inserted into the drive system of the cylindrical screen 3 so as to be directly connected to the shaft of the motor 17 . As the buffer joint 32, a fluid joint, a powder joint, or the like is used, and has a shock absorption function and an overload protection function at startup and operation. If something that cannot be crushed is caught during operation, an abnormal impact torque will be transmitted to the drive system of the cylindrical screen 3, but this impact torque will be absorbed by the buffer joint 32, and one side of the buffer joint 32 will be Since it is directly connected to motor 17, the rotation speed is the same as motor 1.
Since the rotational speed does not rise above the synchronous rotational speed of 7, an accident in which the buffer joint 32 is destroyed due to centrifugal force due to an abnormal increase in the rotational speed does not occur.

なる効果を奏することができる。In addition to this structure, it is even safer if the torque detector 21 detects abnormal torque and controls the drive mechanism so that the torque is reduced. According to the present invention, even if abnormal torque occurs, such as when something that cannot be crushed is caught, this can be buffered, and furthermore, the shock absorbing joint can be prevented from running away, preventing damage accidents caused by running away, and ensuring safe crushing. It is possible to provide a drive device for a separator, which can have extremely great practical and safety effects.
