As shown in FIG. 5 and FIG. 6, the cutting means 9 shoots the onion T from the conveying end portion of the conveying means 8 with the chute 90.
The onion T which was received was conveyed through the conveying onward direction, and while the conveyed onion T was conveyed in the conveying direction c, the direction of the foliage T2 was turned downward, and thereafter the downward foliage T2 was cut, and the foliage T2 was removed. It is a multi-row-compatible transport cutting device or the like that sends onions T from the transport end portion to the lifting transport means 10 on the downstream side.

The cutting means 9 is composed of, for example, five cutting units 91 having the same structure and arranged side by side in the direction intersecting the carrying direction C. Each cutting unit 91 includes two parallel elongated rotating bodies 93 each having a spiral feed portion 92 formed on the outer peripheral surface thereof, and a disc blade 94 arranged near the conveyance end portion of the rotating bodies 93. And basin 95

Further, a defective product container 17 is arranged below the conveyance end of the belt conveyor 105. In addition,
The belt conveyor 105 can be housed so as not to project from the side end of the machine frame 2 when not in operation.

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

Onion T with foliage T2 taken out from the container 5 onto the supply means 7 by the operation of the take-out means 6
Is transported in the transport direction B by the supply means 7 in the mounted state, and is supplied to the transport start end side of the transport means 8.

The plurality of onions T supplied to the starting side of the conveying means 8 are conveyed in the conveying direction B by the vibration of the conveying means 8 itself, and the entwined foliage portions T2 of the adjacent onions T are loosened and guided. It is guided in the groove 50 and is arranged in a plurality of rows while being separated one by one.

At this time, the rotating plate 79 of the rotating body 75 on the conveying end side.
However, the movement of the onion T in the transport direction b is regulated so that the onion T is slightly moved upward and the brake is applied, and the onion T is once arranged in parallel on the guide groove 50 along the transport direction b. That is, the onions T are arranged adjacent to each other on the guide groove portions 50 by the braking action of the divided rotating plate portions 82 of the rotating plate 79.

When the rotating plate 79 is further rotated upward by the pressure of the onion T, one onion T is discharged from each of the divided rotating plate portions 82, and the discharged onion T is After being brought into contact with the row number reducing section 53 to change its direction, it is delivered onto the conveyance start end of the corresponding cutting unit 91 of the cutting means 9.

The onion T delivered onto the transport start end of the cutting unit 91 is transported in the transport direction C while the foliage portion T2 is directed downward, and then sandwiched by the disc blade 94 and the receiving plate 95. Thus, the foliage portion T2 is cut and removed.

The onion T from which the foliage T2 has been removed
After being lifted and conveyed by the lifting and conveying means 10, it is supplied onto the sorting and conveying means 11 and, during the conveyance by the sorting and conveying means 11 in the conveying direction D, a sorting operation is performed by an operator.

The onion T which meets the standard is the non-defective transportation means 14
After passing through the belt conveyor 101, it is dropped from the chute 102 toward the non-defective container 15 and is accommodated in the non-defective container 15. Non-standard onion T (long ball, rotten ball, peeled ball, deformed ball, etc.) is a chute 104a of defective product conveying means 16.
And via the contact chute 104b, the belt conveyor 105
It drops from the container toward the defective product container 17 and is accommodated in the defective product container 17.

Here, the amount of the onion T taken out on the supplying means 7 by the operation of the taking-out means 6 is not constant, and, for example, when the amount of the onion T exceeding the predetermined amount is taken out on the feeding means 7. As shown in FIG. 1, the onions T are stacked in a plurality of stages in the storage section 62 of the transporting means 8, and the transport start end side rotating body 61 is pushed by the onions T and is set upward by a set angle. When rotated, the detection means 71 is turned on and outputs a detection signal to the control means 72. Then, the supply means 7 is stopped by the control of the control means 72, and the supply of the onion T to the conveying means 8 is stopped.

Onion T stored in multiple stages in the storage section 62
Is a divided rotating plate portion 70 of the rotating plate 67 of the transport start end side rotating body 61.
By the braking action of, the sheet moves in one step and moves in the transport direction (b).

When the amount of the onion T in the storage section 62 is reduced to some extent, the transport start end side rotating body 61 rotates downward by its own weight, and the detecting means 71 is turned off. Then, the supply means 7 is operated by the control of the control means 72, and the supply of the onion T to the transport means 8 by the supply means 7 is restarted. In this way, the supply means 7 operates intermittently in conjunction with the detection means 71,
The amount of onion T on the conveying means 8 is kept constant. That is, the detection means 71 automatically supplies a fixed amount, and a small number of people work.

In this way, according to the above-described embodiment, the control means 72 controls the drive motor 33 of the supply means 7 in accordance with the rotation of the transport start end side rotating body 61 located upstream of the transport means 8. As a result, the amount of onion T supplied by the supply means 7 is limited. Therefore, for example, an operator does not need to monitor the amount of agricultural products and manually operate the supply means 7, and the onion on the carrier 41 of the carrier means 8. A quantitative flow of T can be easily realized.

Further, a quantitative flow of the onion T can be realized more reliably by the function of reducing the number of steps based on the braking action of the transport start end side rotating body 61. Therefore, the transport means 8 can remove the foliage portion T2 of the onion T. You can surely loosen the entanglement,
In addition, the cutting means 9 can be properly aligned for cutting.
Further, since the onion T is uniformly transported by the sorting and transporting means 11 located downstream of the transporting means 8, it is possible to perform sorting work without waste.

Further, the parallel function based on the braking action of the conveying end side rotating body 75 at the downstream portion of the conveying means 8 stabilizes the onion T from the conveying end portion of the conveying means 8 toward the conveying start end portion of the cutting means 9. Can be sent to. Therefore,
For example, the onion T etc. that slipped from the transport start end side rotating body 61
It is possible to prevent the cutting means 9 from rolling vigorously or being sent to a position other than the transport start end portion of the cutting means 9, and the cutting means 9 can appropriately cut the foliage portion T2.

Further, since the transport end side rotary body 75 has a plurality of divided rotary plate portions 82 positioned corresponding to the guide groove portions 50, for example, one transport end side rotary body 75 is formed in a single shape. It is possible to prevent the onion T from being adversely affected by the difference in the size of the onion T, as compared with the case where it is configured by the rotating plate. Therefore, for example, when a relatively large onion T moves on the one guide groove 50, the flow of the onion T on the other guide groove 50 adjacent to the one guide groove 50 becomes fast. Etc. can be prevented.

[0069]

According to the first aspect of the present invention, the control means controls the supply means in accordance with the rotation of the transport start end side rotating body which is vertically rotatable on the transport start end side of the transport means. Therefore, for example, the operator does not need to monitor the amount of the crop and manually operate the supply means, and the quantitative flow of the crop can be easily realized.

According to the second aspect of the present invention, the detection means detects that the conveyance start end side rotating body has been pushed by the agricultural product and rotated upward by a predetermined angle, and outputs a detection signal. Since the supply means is controlled based on the detection signal from the detection means and the supply of the agricultural products by the supply means is stopped, for example, the operator does not need to monitor the amount of the agricultural products and manually operate the supply means, The quantitative flow of can be easily realized.
