It is better not to protrude further from the front.

Next, using the bulb crop preparation machine described above,
A preferred working method for harvesting onions, which are typical examples of ridge-grown bulb crops, will be described. In a state where a number of ridges h are formed in parallel and onions w are planted in a plurality of rows on each ridge h, all the onions w of each ridge h are pulled out by using a known onion harvesting machine or the like, and the upper surface thereof is extracted. And let it dry for one or two days. As a result, the surface of the onion bulb portion (spherical portion) w1 becomes somewhat hard and hardly damaged.

In this state, the bulb crop preparation machine T according to the present invention is made to enter a specific ridge h to be treated, which is arbitrarily selected by the operator. The aircraft is steered by holding the steering handles 68, 68 from above. In addition, a large number of containers cn are placed on the container receiving surface portion 224 in the horizontal state, for example, in a state where the containers cn are stacked.

On the ridge h into which the machine enters (the ridge to be processed), the machine is set in the correct direction and position along the ridge h. The extended supply transport unit 3a is fixed in a suitable inclined state around the fulcrum shaft 201, or is fixed in a horizontal state as shown in FIGS. 1 and 2, and when fixed in a horizontal state, the foliage holding and transporting unit is used. The thirteen transport belts 210, 210 are preferably detached from the pulleys 212, 213, and the temporary container kc is preferably placed on the upper surfaces of the case members 202, 202. Even if the transport belts 210 are removed, if the extended supply transport section 3a is horizontal, the onion w can be transported only by the upper bulb crop support transport section 12, and there is no problem. In addition, the containers cn are arranged densely in the front-rear direction on the container receiving surface, and at this time, one empty container cn is closed at the lower end opening 58 of the square tube portion 58 of the bulb portion sending section 5.
It is located just below a.

Thereafter, under the operating condition of the engine 69,
The work clutch lever 86 is engaged, whereby the bulb crop supply / transport section 3 and the bulb crop preparation processing section 4 are activated while the machine body is stopped.

In this state, the onions w scattered around the front of the machine in the ridge h to be processed are supplied to the extended supply transport section 3a. Now, assuming that the extended supply transport unit 3a is fixed in an inclined state as shown in FIG. 7, the operator puts the onion w one by one in the inverted posture in the bulb crop supply transport unit 11a.
Are sequentially supplied to the transfer start end point p1 of FIG. On the other hand, assuming that the extended supply transport section 3a is fixed in a horizontal state as shown in FIGS. 1 and 2, the operator picks up the onion w on the ridge h and collects it in the temporary storage container kc, or The onion w is picked up and collected by holding the temporary storage container kc, and each of the collected onions w is placed in an inverted position in a facing position of the conveyor belts 15 and 15 within the length range of the extended supply conveyor 3a. According to this, the operator does not need to bend and pick up the onion w for each onion w, and the burden on the body is remarkably reduced. Since the supply possible range becomes longer in the front-rear direction, simultaneous supply by a plurality of persons becomes possible and work efficiency is improved.

The onion w thus supplied is supplied by the bulb crop supporting and transporting unit 12 and the foliage holding and transporting unit 13 in the extended supply and transporting unit 3a, or when the transport belts 210 of the foliage holding and transporting unit 13 are removed, the bulbs are removed. It is conveyed to the bulb crop supply / conveyance means 11 in the front case 7 only by the crop support / conveyance section 12, and then supplied horizontally and rearward to the bulb crop preparation processing section 4 by the bulb crop support / conveyance section 12 and the foliage downward pulling conveyance section 14. Is done. In this supply conveyance, the bulb crop support conveyance part 12 supports the onion bulb part w1 from below without constricting the onion stem leaf part w2, and conveys it rearward. The onion stem and leaf portion w2 is received and conveyed backward while being sequentially pulled downward.

While the bulb crop supporting and transporting unit 12 is transporting the onion w, the pair of left and right disc blades 28 of the foliage cutting device 25 reach the stem pulling and transporting unit 14 and have an onion stem and leaf part w2 of approximately 5 cm to 15 cm. The leading-edge portion w2 'is cut away while leaving the original portion of the degree. At this time, the foliage w2 of the onion w hangs down by its own weight, and is smoothly and accurately separated from the onion w by the disk blade 28. The separated leading edge portion w2 ′ falls directly below and is received by the conveyor belt 30 of the first foliage discharging device 29, and is then conveyed to the right outside of the machine base 2 to be processed on the ridge h to be processed. It is released into the groove in contact with the side of the ridge h.

The disk blades 42, 42 controlled in this manner sequentially cut off the roots of the onion bulbs w1 conveyed backward by the bulb crop processing / conveying unit 34 without damaging them, and thus are cut off from the onion bulbs w1. The dropped onion roots fall downward, most on the conveyor belt 54 of the second foliage ejector 36, and others on the ridges h.

When the onion bulb w1 passes directly below the disk blades 42, 42, the rear guide wheel 43b comes into contact with the surface of the onion bulb w1 and moves along the surface of the onion bulb w1 as the onion bulb w1 is transported. By rolling, a pair of disk blades 4
2 and 42 are sequentially guided downward, and the disk blades 42 and 42 are kept apart from the onion bulb portion w1 until the onion bulb portion w1 passes below the disk blades 42 and 42. After the portion w1 has passed this portion, the disk blades 42, 42 have reached the lowermost position and are ready for the next processing of the onion bulb portion w1.

On the other hand, while the onion stem leaves w2 released from the bulb crop supply / transportation means 11 are transported to the bulb crop processing / transportation section 34, the disk blades 52, 52 of the finishing cutting device 35 existing below the root cutting device 32. And these disk blades 52, 52
While the onion bulb w1 is being conveyed by 6, 46, the stem side of the foliage is cut off from the onion bulb w1. Onion bulb w1
The original side portion of the onion stem and leaf portion w2 cut off from below is received downward by the conveyor belt 54 of the second stem and leaf portion discharging device 36 while being guided by the guide plate 55.

The original side portion and the onion root portion of the onion stem and leaf portion w2 thus positioned on the conveyor belt 54 are conveyed to the right and outside of the machine stand 2 and from the right side of the machine stand 2 on the processing target ridge h. Alternatively, the onion bulb w1 that is released into the groove in contact with the side of the ridge h and is obtained after removing the onion root and the onion stem leaf w2 from the onion w is a bulb crop treatment. After being transported a little further backward by the transport unit 34, it is released from the bulb crop processing transport unit 34. The released onion bulb portion w1 falls on the plurality of guide rod members 62 and falls down into the bulb crop receiving portion 57 of the discharge chute 56, and thereafter, on the side where the swing switching plate 59 does not exist, that is, in FIG. And the swing switching plate 5 as shown in FIG.

, Falls down from the lower end opening 58a, and is received by the container cn immediately below the lower end opening 58a on the container receiving surface of the container base 223.

After all of the onions w on the processing target ridge h around the front of the machine are supplied into the machine, the running clutch lever 71 at the rear of the machine or the running clutch lever 78 at the front is operated to move the machine by an appropriate distance. The onion w on the processing target ridge h in the vicinity of the front of the machine is again supplied to the inside of the machine in this state, and the above operation is repeated thereafter. Thus, the container cn immediately below the lower end opening 58a of the square tube portion 58 is supplied with the onion bulb portion w1 after the preparation process one after another. When this container cn is full, it is moved forward on the container receiving surface to place another empty container cn in place of this, and this operation is performed every time the container cn becomes full. repeat. Many of the full containers cn can be placed on the container base 223 by stacking them. Then, when an appropriate number of the full containers cn have accumulated, the operator stops traveling of the machine body and lowers the machine body on the ridge h or carries it out of the field. When the preparation process on one processing target ridge h is completed,
It moves to the ridge h to be processed next and performs the same operation.

After the preparation process of all the ridges h is completed, the container receiving surface portion 224 of the container table 223 is pulled up around the longitudinal axis 229 of the folding mechanism 225 so as to be in an upright state as shown by a virtual line ka in FIG. Then, this state is maintained by a not-shown locking means. Since the container table 223 in this state is in a folded state and the amount of lateral extension thereof is small, it is difficult for the container table 223 to come into contact with other objects during traveling of the body.
