Further, the supply unit 4 is provided with dust rising prevention means 6 for preventing the dust generated when the onion drops from the container 5 from flying up. In the dust rising prevention means 6, a sheet 62 is detachably attached to a frame 61, and the sheet 62 covers the inside of the guide plate 25 from above so that dust does not rise. Furthermore, the dust rising prevention means 6 can be turned to stop the shaft 63 in the left-right direction.

The dust rising prevention means 6 has a moving device 7 that moves the container 5 and the lift device 41 emptied by the fall of the onion from the container 5 to the supply start end side, that is, the rotation start end side of the lift device 41. is doing. In this moving device 7, the rod rod 72 is assembled to the assembly portions 71 on the left and right of the guide plate 25, the compression spring 73 is assembled to the rod rod 72, and the rod rod 72 is assembled to the mounting portion 64 on the frame 61. It is a thing. The rod rod 72 has a plurality of holes for adjusting the strength of the compression spring 73 by changing the position of the pin 74.

  Next, the conveyance part 8 is arrange | positioned and comprised from the front side of the machine casing 2 to the rear side in order of the waveform conveyor 9, the vibration conveyor 10, the cutting conveyor 30, and the lifting conveyor 70.

  The corrugated conveyor 9 is disposed in a state where the front is inclined with a wave-shaped endless belt, and the onion supplied from the container 5 is sequentially conveyed backward.

And the onion conveyed from the corrugated conveyor 9 is conveyed back by the vibration conveyor 10 provided with the vibration generator 11 while loosening the onion in which the foliage is entangled. The vibration conveyor 10 conveys the onion while vibrating vertically and horizontally by the vibration generator 11.

Further, the onion loosened by the vibration conveyor 10 is conveyed to the cutting conveyor 30. This cutting conveyor 30 is conveyed backward while cutting the foliage of the onion. Further, the cut leaves are dropped and carried out from the rear end portion of the machine frame 2 by the carry-out conveyor 31.

Then, the onion from which the foliage has been cut is lifted upward by the lifting conveyor 70 and conveyed to the sorting unit 50.

In the sorting unit 50, the transport roller 51 is rotated toward the front of the machine frame 2, and the onion transported from the transport unit 8 is turned into a good product and a defective product by the operator. Sorting. Here, the non-defective onion is transported from the transport roller 51 to a slide conveyor 52 slidable in the left-right direction, and accommodated in a non-defective container 53 provided on the left and right sides of the machine casing 2.

In addition, the defective onion is dropped onto the carry-out conveyor 55 by being put into the chute 54. And it is accommodated in the inferior goods container 56 provided in the left side of the machine casing 2 from the carrying-out conveyor 55. FIG.

Next, the operation and the like of the above embodiment will be described.

By the operation of the lift device 41 of the supply unit 4, the onion with foliage is supplied from the container 5 to the corrugated conveyor 9 of the transport unit 8. The dust generated at this time can be prevented from flying by the sheet 62 of the dust rising prevention means 6, so that the worker in the sorting unit 50 and other workers do not inhale the dust and work safely. Furthermore, since dust does not fly up, it does not adversely affect the machine body.

Conventionally, the lift device 41 is rotated about the shaft 24 of the supply unit 4, and the position where the onion in the container 5 falls and the container 5 becomes empty has exceeded the fulcrum above the shaft 24. Position. This is because the container 5 itself is so heavy that when the lift device 41 is rotated, the container 5 also moves toward the guide plate 25 as the onion drops. When trying to return the container 5 to the supply start end side, the empty container 5 cannot be returned to the original rotation start end side while being placed on the guide plate 25.

However, according to the present embodiment, when the onion is dropped from the container 5, the container 5 is dropped while being supported by the frame 61 of the dust rising prevention means 6. Then, as the onion in the container 5 decreases, the dust rising prevention means 6 rotates little by little around the shaft 63 by the repulsive force of the compression spring 73 of the moving device 7 provided in the dust rising prevention means 6. Then, the container 5 and the lift device 41 are moved so as to be pushed back to the supply start end side. Therefore, the container 5 that has exceeded the fulcrum moves together with the lift device 41 to a position below the position beyond the fulcrum by the moving device 7 when the inside of the container 5 becomes empty. Since it can be easily returned to the supply start side by movement, the replacement with the container 5 to be supplied next can be performed smoothly.

Next, the onion supplied to the transport unit 8 is first transported to the vibrating conveyor 10 by the corrugated conveyor 9. Since the vibration conveyor 10 is conveyed while being vibrated up and down, left and right, the onion in which the stems and leaves are intertwined is loosened and conveyed to the cutting conveyor 30 with the onions separated.

Then, the cutting conveyor 30 conveys the onion to the lifting conveyor 70 while cutting the onions and leaves of the onion. At this time, the cut foliage is carried out from the rear end of the machine frame 2 by the conveyor 31.

Further, the onion conveyed upward by the lifting conveyor 70 is conveyed to the sorting unit 50. The sorting unit 50 sorts the product into a non-defective product and a defective product by an operator.
The non-defective onion is transported from the transport roller 51 to a slide conveyor 52 slidable in the left-right direction, and is accommodated in a non-defective container 53 provided as a pair on the left and right sides of the machine casing 2.

Further, the defective onion is dropped onto the carry-out conveyor 55 by being put into the chute 54, and is accommodated in the defective-goods container 56 provided on the left side of the machine frame 2 from the carry-out conveyor 55.

  The material of the sheet 62 of the dust rising prevention means 6 in the present embodiment is transparent vinyl chloride, but is not limited thereto, and may be polyethylene or cloth, and is not particularly limited. In this embodiment, the sheet 62 is detachable. However, the sheet 62 may be wound around the frame 61 and pulled out as necessary.
