[Structure] The excavating blade 3 is provided below the front end side of a conveyor 2 obliquely installed toward the lower front of the traveling device 1, and guide rollers 4 and the like are arranged on both front sides of the excavating blade 3. In the sweet potato harvesting machine, the arm 5 which is installed above the front side of the digging blade 3 so as to be able to support the guide roller 4 and the like has a guide rod 6 for a green onion that is substantially V-shaped in a plan view and is detachable It is configured by being attached to.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guidance device for green onions of a sweet potato harvester, which can also effectively harvest green onions.

[0002]

[Prior art]

 Conventionally, as seen in Japanese Patent Application No. 4-88308 filed by the applicant of the present invention, the excavator is equipped with a digging blade below the tip side of a conveyor obliquely installed toward the lower front of the traveling device. In a sweet potato harvesting machine that is configured by arranging guide rollers and the like on both front sides of the cutting blade, when the harvesting machine harvests the green onions cultivated in one row, the green onion that is dug by the cutting blade is a conveyor. The posture is distorted upwards.

[0003]

[Problems to be solved by the device]

 Therefore, when post-processing the green onions conveyed upward by the conveyor, it is difficult to work because it is scattered and it is difficult to align, and it is also difficult to work, and it gets caught on the conveyor due to its poor appearance. It is difficult to take it out.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such problems and to effectively harvest green onions. Therefore, a digging blade is provided below the tip of the conveyor that is installed obliquely toward the lower front of the traveling device. In addition, in the sweet potato harvester configured by arranging guide rollers and the like on both sides of the front of the digging blade, the arm installed to support the guide rollers and the like above the front side of the digging blade is The onion guide rod, which has a substantially V-shape when viewed from above, is detachably attached.

[0005]

[Operation] Therefore, when harvesting green onions, if the green onion guide rod is attached to the arm, the upper end of the planted green onion leaf will be received by the green onion guide rod as the aircraft advances. It is pushed down forward, and when the roots excavated by the digging blade are placed on the conveyor and transported backwards, the roots of the green onions are aligned first and the tops of the leaves are aligned rearward. Will be transported one after another.

【Example】

FIG. 1 is a schematic perspective view of a sweet potato harvester. On the machine supported by both traveling devices 1, an engine section E, an operation section F, a front management seat S ₁ , a storage seat S ₂ , A container stand 7 is provided, and a conveyor 2 is installed between both parallel side plates 8 that are obliquely provided toward the lower front part between both traveling devices 1, and a rear conveyor 2a is further provided from the end of the conveyor 2 toward the rear. Is provided, and a digging blade 3 projecting forward from below the tip of the conveyor 2 is provided between both digging part side plates 8a extending from the tips of both side plates 8. A fulcrum of rotation rotatably mounted between the tips of the supporting portions 8b extending from the middle of the shaft. The tips of both supporting rods 10 extending forward from the shaft 9 are connected to the lateral arms 5, and the fulcrum of rotation is also provided. The piston rod of the cylinder 12 driven by a motor 11 installed above the shaft 9 The tip side of the carriage 12a is rotatably linked to the arm 5, and the guide roller 4 and the coulter 4a are respectively provided under the two support rods 13a and 13b vertically provided from both ends of the arm 5. It is erected and constructed in the same way as the conventional structure.

A holder 14 is provided so as to project from the middle portion of the arm 5 to the front, and the front of the onion guide rod 6 formed as shown in FIGS. A supporting rod 6a that can be detachably fitted to the holder 14 is projected from the end portion, and a locking pin 16 that can be detachably attached to the lower end of the split pin 15 is fitted to the holder 14 and the supporting rod 6a from above. It is configured so that it can be inserted.

Therefore, when harvesting sweet potatoes, the onion guide rod 6 is removed, but when harvesting the green onions, the onion guide rod 6 is attached to the arm 5 as shown in FIGS. 1 to 3. When it is installed facing forward, the upper end of the leaf portion 17a of the planted green onion 17 is received by the guide rod 6 and pushed forward as indicated by a, as shown in FIG. 2, as the aircraft advances. When the root portion 17b excavated by the digging blade 3 is placed on the conveyor 2 and conveyed rearward, the root portion 17b of the green onion 17 comes first and the leaf portion 17a as shown by (b). Since the upper ends are aligned and transported one after another, the worker who sits at the seat and performs the post-treatment work can easily perform the work.

[0009]

[Effect of device]

 As described above, according to the present invention, when the green onion is harvested, if the green onion guide rod 6 is attached to the arm 5, the upper end of the leaf of the planted green onion is guided by the green onion guide rod 6 as the machine body moves forward. When the roots excavated by the digging blade 3 are placed on the conveyor 2 and conveyed backward, the roots of the green onions come first and the upper ends of the leaves. All of them are evenly arranged so that they can be transferred one after another, which makes post-harvest post-treatment work for post-harvesting easier and easier, and removing and attaching the onion guide rods 6 Only then, green onion can be harvested by the sweet potato harvester, which is a feature that can be suitably implemented.
