Next, using the above-mentioned bulb crop preparing machine,
A desirable use example and an action of the onion, which is a typical example of the ridge-grown bulb crop, will be described. A large number of ridges h are formed in parallel, and onion w is planted in multiple rows on each ridge h, using a known onion harvester, etc., and pulling out all the onion w of each ridge h. Allow to dry for 1 to 2 days. As a result, the surface of the spherical portion w1 becomes somewhat harder and is less likely to be damaged.

After that, an arbitrary ridge h to be treated, which is arbitrarily selected by the operator of the bulb crop preparing machine according to the present invention.
In this case, the operator operates the aircraft by holding the steering handles 68, 68 from the rear of the aircraft.

On the ridge (ridge to be processed) h into which the machine body has entered, the machine body is set in the correct direction and position along the ridge h. The extension supply / conveyance unit 3a is fixed in an appropriate inclined state around the fulcrum shaft 201, or fixed in a horizontal state as shown in FIG. The belts 210, 210 are pulleys 212,
It may be removed from 213. At this time, even if the conveyor belts 210 and 210 are detached, if the extension supply conveyor 3a is horizontal, the onion w will be conveyed only by the upper bulb crop placing conveyor 12 and no trouble will occur.

On the other hand, the operator judges whether or not the average size as an example of the typical size of the onion spherical portion w1 to be actually processed is larger than the intermediate size (for example, a diameter of about 95 mm). In this case, when it is determined that the average size is larger than the intermediate size, the left and right conveyor belts 46, 46 of the bulb crop processing and conveying section 34 are set to the lower bolts as shown in FIG. When fixed at a high position related to the hole d1 (that is, a height at which the onion bulb portion w1 up to LL size can be processed), and conversely, when it is determined that the average size is smaller than the intermediate size,
The left and right conveyor belts 46, 46 are fixed at a low position (that is, a height at which the onion spherical portion w1 up to S size can be processed) associated with the upper bolt hole d2.

After that, the engine 69 is brought into the operating state,
Since the work clutch lever 86 is operated to be operated, the machine body is kept stopped, and the bulb crop supply / conveyance unit 3 and the bulb crop preparation processing unit 4 are activated.

Under this condition, the onions w scattered around the front part of the machine body in the ridge h to be processed are supplied to the extension supply / conveyance unit 3a. Now, assuming that the extension supply / conveyance unit 3a is fixed in an inclined state as shown in FIG. 5, the worker should take the onion w one by one and invert the bulb crop supply / conveyance unit 11a.
Are sequentially manually supplied to the transport start end point p1. On the other hand, if the extension supply / conveyance unit 3a is fixed in a horizontal state as shown in FIG. 1, the worker picks up the onion w on the ridge h and collects it in the container, and one of the onion w thus collected. Conveying belt 1 within the length range of the extension supply conveying unit 3a
It is manually supplied in such a manner that it is inserted from above or from the front between the facing portions of the 5th and 15th portions. At this time, the foliage holding and conveying section 1
It is convenient to remove the conveyor belts 210, 210 of No. 3 so that the conveyor belts 210, 210 can be supplied anywhere within the length range of the extended supply conveyor unit 3a.

The onion w supplied in this manner is supplied by the bulb-plant-carrying and carrying section 12 and the foliage-holding and carrying section 13 in the extension-feeding and carrying section 3a, or the carrying belt 2 of the foliage-holding and carrying section 13.
When 10 and 210 are removed, the bulb crop placing and carrying section 1
Only by 2 is conveyed to the bulb crop supply / transport means 11 in the front case 7, and then horizontally transported to the bulb crop preparation processing section 4 by the bulb crop placement transport section 12 and the stem pulling transport section 14. In this feeding and conveying, the bulb crop placing and conveying unit 12 supports the onion bulb portion w1 from below without conveying the onion stem leaf portion w2 and conveys it to the rear side. The onion stalk leaf portion w2 is received and sequentially pulled downward and conveyed backward.

In the process of transporting the onion w by the bulb crop placing and transporting unit 12, the pair of left and right disk blades 28 of the rough cutting device 25 reach the stalk pulling and transporting unit 14 of the onion foliage w2 of about 5 cm. The leading portion w2 'is cut off leaving the base side portion of about 15 cm. At this time, the foliage w2 of the onion w
Is in a state of hanging down due to its own weight, and the disc blade 28
As a result, the leading edge portion w2 'is smoothly and accurately separated from the onion w. The detached leading edge portion w2 ′ falls directly below to convey the conveyor belt 30 of the first foliage discharging device 29.
Then, it is conveyed to the outside of the right side of the machine base 2 and discharged on the ridge h to be processed or in the groove in contact with the side portion of this ridge h.

The onion bulb portion w1 conveyed rearward by the bulb crop supplying / conveying means 11 reaches the bulb crop treating / conveying section 34 in a state of being arranged on the conveyor belts 15 and 15, and the bulb crop treating / conveying section 34. Then, the conveyor belts 46, 46
Then, the left and right side portions of the onion spherical portion w1 which has reached here are firmly sandwiched and conveyed backward so as not to change its posture.

During this conveyance, the root raising brush device 3
3 raises the onion root part upward and arranges it in an upright state, and thereafter the onion bulb part w1 is the root cutting device 32.
Guide rod member 43 when approaching the disk blades 42, 42 of
a and 43a are brought into contact with the surface of the onion spherical portion w1 and slide on the surface of the onion spherical portion so that the pair of disc blades 42, 42 are sequentially guided upward and their height relative to the onion spherical portion w1 is increased. Control to the optimum state. The disc blades 42, 42 controlled in this manner are used for the bulb crop processing and transporting section 34.
Thus, the root of the onion bulb portion w1 conveyed to the rear is sequentially cut off without damaging the onion bulb portion, and thus the onion root portion separated from the onion bulb portion w1 falls downward.

When the onion spherical portion w1 passes directly under the disc blades 42, 42, the pair of disc blades 42, 42 are inclined rearwardly upward (about 10 degrees), and the onion spherical portion w1 becomes the disc blades 42, 42. It is prevented from being damaged. The onion spherical portion w1 is the disc blade 4
After passing directly below 2, 42, the disc blades 42, 42 gradually descend while reaching the lowest position in relation to the onion spherical portion w1, and prepare for the processing of the next onion spherical portion w1.

On the other hand, the onion foliage w2, which is conveyed by the bulb crop processing and conveying section 34 and the stem pulling and conveying section 14 in a constant height and posture, is present below the root cutting apparatus 32. Disc blades 52, 5
2, the disc blades 52, 52 cut off the stem-and-leaf part base side portion from the onion bulb portion w1 during the conveyance of the onion bulb portion w1 by the ball conveying belts 46, 46. The root side portion of the onion stalk leaf portion w2 separated here is dropped downward and guided by the guide plate 55 to be received by the conveyor belt 54 of the second foliage portion discharging device 36.

The root side and the onion root of the onion stalk leaf portion w2 located on the conveyor belt 54 are conveyed to the right lateral outside of the machine base 2 and from the right side of the machine base 2 to the ridge h to be processed or The onion globular part w1 which is the product of the preparation process obtained after removing the onion root part and the onion stalk leaf part w2 from the onion w is discharged into the groove in contact with the side part of the ridge h. After being conveyed a little further backward by the section 34, it is released from the bulb crop processing and conveying section 34. The released onion spherical portion w1 falls on the plurality of guide rod members 62 and rolls down into the bulb crop receiving portion 57 of the discharge shooter 56, and thereafter, the square tubular member 58 on the side where the swing switching plate 59 does not exist. When the swing switching plate 59 is located on the right side as shown in FIGS. 4 and 11, it rolls down through the left side rectangular tube member 58 and falls from the lower end opening 58a thereof.

Next, the action around the bulb crop processing and transporting section 34 will be described in more detail. When the left and right conveyor belts 46, 46 are set to the high position suitable for the onion spherical portion w1 up to the size LL, the conveyor belts 46, 46 move them to the S position.
The height is increased by an appropriate length as compared with the low position adapted to the onion bulb portion w1 up to the size. Therefore, the left and right conveyor belts 46, 46 are held relatively high with respect to the bulb crop placing and conveying section 12 and the foliage finishing device 35.

As described above, when the bulb crop processing and transporting section 34 is in the high position, when the onion bulb portion w1 larger than the intermediate size is transported to the bulb and crop placing and transporting section 12 and reaches the transport end. , Left and right conveyor belts 46, 46
Holds the left and right side portions of the onion spherical portion w1. here,
Although there are various sizes of onion spherical parts w1 larger than the intermediate size, there are various sizes. Therefore, when the pinching state is seen in more detail, as shown in FIG. When the onion bulb portion w1 larger than the intermediate size is relatively small, 46 and 46 sandwich a relatively high range n1 including the maximum outer diameter portion of the bulb portion w1, and the onion bulb portion w1 has an intermediate size. When it is, the right lateral range n2 of the maximum outer diameter portion of the spherical portion w1 is sandwiched, and when the onion spherical portion w1 is relatively large, a relatively low range n3 including the maximum outer diameter portion of the spherical portion w1. To pinch. Thus, even if the sandwiching range of the onion spherical portion w1 by the transport belts 46, 46 changes in the vertical direction, the sandwiching surface portions of the transport belts 46, 46 are relatively soft, so that they follow the surface of the onion spherical portion w1. It deforms and comes into surface contact, and firmly supports it.

On the other hand, when the left and right conveyor belts 46, 46 are set to the low position adapted to the S-sized onion bulb portion w1, these conveyor belts 46, 46 adapt them to the LL size onion bulb portion w1. Compared to the high position, it will be lowered by an appropriate length. Therefore, the left and right conveyor belts 4
6 and 46 are kept relatively low with respect to the bulb crop placing and conveying section 12 and the foliage finishing cutting device 35.

As described above, when the bulb crop processing and transporting section 34 is in the low position, when the onion spherical portion w1 smaller than the intermediate size is transported to the bulb and crop placing and transporting section 12 and reaches the transport end. , Left and right conveyor belts 46, 46
Holds the left and right side portions of the onion spherical portion w1. here,
Although there are various sizes of onion spherical parts w1 smaller than the intermediate size, there are various sizes. Therefore, when the pinching state is seen in more detail, as shown in FIG. When the onion bulb portion w1 smaller than the intermediate size is relatively small, 46 and 46 sandwich a relatively high range n4 including the maximum outer diameter portion of the bulb portion w1, and the onion bulb portion w1 is intermediate. When the size is large, the right lateral range n5 of the maximum outer diameter portion of the spherical portion w1 is sandwiched, and when the onion spherical portion w1 is relatively large, a relatively low range including the maximum outer diameter portion of the spherical portion w1. n
Hold 6 In this way, even if the sandwiching range of the onion spherical portion w1 by the conveyor belts 46, 46 changes in the vertical direction, the sandwiching surface portions of the conveyor belts 46, 46 follow the surface of the onion spherical portion w1 as before. It deforms and comes into surface contact, and firmly supports it.

On the other hand, the lowest position in the free state of the disk blades 42, 42, which is the main part of cutting of the root cutting device 32, is vertically displaced in association with the height change of the conveyor belts 46, 46 of the bulb crop processing conveyor 34. Since it is vertically displaced in the same manner as the transmission case 40, the lowest position is appropriately lower for the onion bulb portion w1 smaller than the intermediate size, and to the onion bulb portion w1 larger than the intermediate size. On the other hand, it will be appropriately high. Thereby, the guide rod member 43a,
The reference numeral 43a appropriately contacts the onion spherical portion w1 regardless of the change in size of the onion spherical portion w1 to control the heights of the disk blades 42, 42 without any trouble. In addition, the left and right conveyor belts 4
Since the vertical width of each of the belts 6, 46 is smaller than the conventional one, the height from the center of the width of each of these belts 46 to the lowest position is smaller than that of the conventional one, which allows the root cutting device 32 to have a particularly small onion spherical portion (for example, 55mm diameter) w
It is possible to deal with the root cutting of 1.

The left and right conveying belts 46, 46 of the bulb crop processing and conveying section 34 are driven pulleys 1 rotated at the same speed.
6a, the left and right input pulleys 92b, 9
Since the effective diameter of 2b is different, these left and right belts 4
The moving speeds of the front-rear facing parts p, p of 6, 46 are different. On the basis of this difference in the moving speed, the onion spherical portion w1 nipped and conveyed by the left and right belts 46, 46 is rotated by about 30 to 90 degrees in a plan view within the range where the raising mechanism of the raising brush device 33 is applied. Is displaced. Therefore, for example, as shown in FIG.
When the onion spherical portion w1 is started to be sandwiched by 6, 46, a part of the root portion w3 of the spherical portion w1 hangs down to the side portion of the spherical portion w1 and the onion spherical portion w1 and each conveyor belt 4 are provided.
Even if it is temporarily sandwiched between the onion 6 and 6, the sandwiched root portion w3 is released from between the onion spherical portion w1 and each of the conveyor belts 46 by the rotational displacement of the onion spherical portion w1. It is in a free state, and the brush brushes 45, 45 are raised.
It is caused to be raised upward by the root raising action by and is cut by the disk blades 42, 42 of the root cutting device 32.

The above embodiment can be modified as follows. That is, a detection means is provided for detecting the size of the spherical portion w1 of the bulb crop w supplied to the bulb crop processing and transporting section 34, and the bulb crop processing and transporting section 34 is based on the detection information of this detection means. A power height changing mechanism is installed to automatically change the height. At this time, the above-mentioned detecting means uses the bulb crop w conveyed by the bulb crop placing and conveying section 34.
It is better to provide it in the middle of the movement locus of.
