Next, using the bulb crop preparation machine described above,
A preferred working method for harvesting onion, which is a typical example of the ridge-grown bulb crop w, will be described. A large number of ridges h are formed in parallel, and the ridge pitch is approximately 1300 mm to 160
The ridge width is about 900 mm or more at about 0 mm.
As shown in FIG. 3, in a state where onions w are planted in a plurality of rows i on each ridge h, all the onions w of each ridge h are pulled out by using a well-known onion harvesting machine or the like, and one day or two Leave to dry for about a day. As a result, the surface of the onion bulb portion (spherical portion) w1 becomes somewhat hard and hardly damaged.

After that, the operator collects the onions w for every two ridges on one ridge h, sets the other ridge h free of the onion w, and lays a band-like net j there. I do. Under this state, the bulb crop preparation machine T according to the present invention is allowed to enter a specific ridge h which is a processing target arbitrarily selected by an operator. At this time, the operator performs processing on the specific ridge h. The onion w existing in the length range as long as the body length of the starting point is moved in advance, and the body is steered from behind the body by holding the steering handles 68, 68.

Then, the ridge into which the airframe has entered (the ridge to be processed)
h, the airframe is set to the correct direction and position along the ridge h, and the discharge gutter 63 adjacent to the ridge h to be processed and on the side where the ridge h on which the net j is laid exists is moved outward and outward. Overhang and fix. At this time, the discharge gutter 63 on the other side is held upright via the interlocking link mechanism 64. Next, the extension gutter 65 on the side from which the discharge gutter 63 extends is adjusted so that the tip thereof is positioned on the net j, and is fixed to the discharge gutter 63.

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, onions w scattered around the front of the machine body in the ridge h to be processed are sequentially placed in the inverted posture at the transport starting end point p1 of the lifting and transporting device 8 forming a part of the bulb crop processing path. To supply. At this time, by manually changing the position of the tip of the lifting and lowering device 8 in the vertical and horizontal directions as needed, the operator can efficiently supply the onion w without fatigue. Depending on the situation, the lifting and conveying device 8 may be detached to directly supply the transport start point p2 of the bulb crop supporting and transporting unit 12 forming the bulb crop processing path.

The onion w supplied in this manner is conveyed rearward by the lifting and conveying device 8 and then passed on to the bulb crop supply / conveying means 11 and thereafter horizontally rearward to the bulb crop preparation processing section 4 by the conveying means 11. It is supplied and conveyed. In this supply conveyance, the bulb crop support conveyance part 12 supports the onion bulb part w1 from below and conveys it rearward, and at the beginning of this conveyance, the attracting brush device 13 applies a rearward feeding force to the onion stem leaf part w2. At the same time, the stem pulling and conveying unit 14 inherits the onion stem and leaf portion w2 and sequentially pulls it downward to convey it in an inverted shape and rearward. The brush bodies 18, 18 of the attracting brush device 13 may hinder the passage of the onion w depending on the type, dry state, etc. of the onion w. In such a case, the brush bodies 18, 18
Is detached from the cantilevered brush drive shafts 19, 19.

When the bulb crop supporting and transporting section 12 transports the onion w, the guide plate 291 on the front side of the body of the belt conveyor 29 is transported.
Even if the foliage w2 of the onion w is long, it does not come into contact with it, or even if it does, it does not hinder the onion w from moving smoothly above the conveyor belt 30. After the onion w has moved above the conveyor belt 30, the pair of left and right disc blades 28 of the foliage cutting device 25 reach the stem pulling transport unit 14, approximately 5 cm of the onion stem and leaf part w 2.
Leave the original part w2 ″ of about 15 cm in the leading part w
Cut 2 '. 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 forward portion w2 'falls directly below and is received by the conveyor belt 30 forming the first foliage discharging device 29, and is then conveyed to the right outside of the body frame 2 to be processed.
It is discharged into the groove k in contact with the top and this ridge h.

The onion w from which the forward part w2 'has been cut is moved rearward on the guide plate 292 of the conveyor belt 30 on the rear side of the body by the bulb crop supply / transportation means 11, and at this time, the foliage of the onion w Since the base side w2 ″ of w2 does not come into contact with the guide plate 292, the onion w2
Is maintained in the posture of the rough cut. In addition, it is possible that the cut-away portion w2 ′ is pushed by the onion w moving on the bulb crop processing path and tries to move to the rear side of the conveyor belt 30 in the body. The guide plate 292 on the rear side of the body of the belt 30 regulates the movement of the forward portion w2 ', separates it from the onion w, guides it on the conveyor belt 30, and drops it.

The onion bulb w1 further conveyed backward by the bulb crop supply / conveyance means 11 is conveyed by the conveyor belts 15,15.
After reaching the bulb crop processing / transporting section 34 in the state of being adjusted above, the nipping / transporting belts 46, 46 firmly clamp the left and right side portions of the onion bulb section w1 that has reached the bulb crop processing / transporting section 34. And convey it backward so that the posture does not change.

During this transport, the root raising brush device 3
3 lifts the onion root upward and arranges it in an upright standing state.
Guide wheels 4 when approaching the disk blades 42, 42
The head frame 38 is sequentially guided upward by rolling on the surface of the onion bulb w1 in contact with the onion bulb w1 in contact with the surface thereof, and the disk blade 4 with respect to the onion bulb w1.
2. Control the height of 42 to an optimal state. The disk blades 42, 42 controlled in this manner are connected to the bulb crop processing and transporting section 34.
The root portion of the onion bulb w1 conveyed backward is cut off without damaging the onion bulb portion w1, and the onion root portion thus separated from the onion bulb portion w1 falls downward, and most of the onion root portion is the second foliage. The discharge means 36 is guided by the guide plates 531 and 532 located on both sides of the conveyor belt 54 and falls on the upper surface of the receiving position of the conveyor belt 54, and the others fall on the ridge 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, the head frame 38 is sequentially guided downward, and the onion bulb w1 is moved to the disk blades 42, 42.
The disk blades 42, 42 are kept apart from the onion bulb portion w1 until they pass below, and after the onion bulb portion w1 passes here, the disk blades 42, 42 reach the lowest position. In preparation for the next processing of the onion bulb portion w1.

On the other hand, the onion bulb portion w1 released from the bulb crop supply / transportation means 11 is transported to the bulb crop processing / transportation portion 34, and the onion leaf portion w2 from which the leading portion w2 'has been cut off is the conveyor belt 54. Guide plate 53 on the front of the fuselage
Through the upper part of 1, it reaches the disk blades 52, 52 of the finishing cutter 35 present below the root cutter 32. At this time, the onion stem and leaf portion w2 in a state where only the forward portion w2 'has been cut off does not come into contact with the guide plate 531 and the onion w is held in the posture at the time of rough cutting. Then, while the disk blades 52, 52 convey the onion bulb w1 by the onion sandwiching conveyance belts 46, 46, the original side portions of the foliage are separated from the onion bulb w1. The original side portion w2 ″ of the onion stem leaf portion w2 separated from the onion bulb portion w1 falls downward and is received on the upper surface of the receiving portion of the conveyor belt 54 while being guided by the guide plates 531 and 532 on both sides of the conveyor belt 54. Can be

At this time, the original part w
2 "may be pushed further by the onion bulb portion w1 or the like during transportation and may further move rearward. In this case, the guide plate 532 on the rear side of the conveyor belt 54 on the body side of the conveyor belt 54 has the original side portion w2". The movement is regulated and separated from the onion bulb w1 and the like, guided to the upper surface of the receiving position of the conveyor belt 54, and dropped.

When the original side portion w2 ″ is cut off from the onion bulb portion w1, the sticky liquid oozes out of the onion w and falls on the upper surface of the guide plate 532. , The original portion w which has already been separated and is falling while being guided by the guide plate 532
2 "adheres to the guide plate 532 due to the adhesive force of the sap and tends to be hindered from dropping smoothly. However, while the disk blades 52, 52 rotate, the cam plates 363, 363 are driven vertically by the disk drive. Since the guide plate 532 is vibrated back and forth with the specific amplitude related to the cam plates 363 and 363 because of being rotated together with the shafts 51 and 51, the original portion w2 ″ that has fallen on the guide plate 532 is Adhesion by the sap is effectively prevented, and the liquid drops smoothly.

The original side portion w2 ″ of the onion stem and leaf portion w2 and the onion root portion thus positioned on the conveyor belt 54 are conveyed to the right and outside of the body frame 2 and processed from the right side of the body frame 2 to the ridge to be processed. The onion bulb w1 which is released after removal of the onion root and the onion stem leaf w2 from the onion w is removed from the onion w or the groove k in contact with the ridge h. 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 the bulb crop of the discharge shooter 56 is discharged. After falling down into the receiving portion 57, the square tube member 58 on the left side when the swing switching plate 59 is located on the right side as shown in FIG. Gutter 6 And it is to fall on the net j ridges h adjacent to tumbled down processed ridges h through the extended trough 65.

After all the onions w on the processing target ridge h around the front of the machine are supplied to 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 machine in this state.
Thereby, while the onion stem-and-leaf part w2 is discharged in a row | line shape in the groove | channel k which contacted the processing target ridge h or on the processing target ridge h,
Onion bulb w1 as a result of the preparation processing is collected in a row on the net j of the ridge h adjacent to the processing target ridge h. In addition,
It is also possible to set the running speed to a low speed and perform the preparation work while moving.

When the processing on the processing target ridge h is completed, the ridge h on which the onion w to be processed next is collected.
Go to and do the same work. At this time, as the ridge h to be processed next, the ridge h closest to the ridge h for which processing has been completed immediately before is selected. Usually, the ridge h moves one ridge h as indicated by a trajectory line m. Is made.
