Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is a foliar treatment for pulling out the foliage part of a rhizome-grown potato and other subterranean crops to harvest potatoes formed at the lower end of the foliage part. Conveying device in machine.

(B) Conventional technology In the conventional transfer device for a foliage processing machine, the transfer device is configured by providing a transfer case that is rotatably fixed around a drive shaft arranged in parallel at the rear part of the sandwich transfer device. The endless belt with a transfer protrusion supported by the transfer case takes over the foliage part from the sandwiching transfer device, and transfers the foliage part to the collecting device placed behind and to the left and right of the transfer device.

(C) Problem to be Solved by the Invention In a conventional transfer device for a foliage processing machine, an endless belt with a transfer protrusion having a transfer protrusion supported by the transfer case is installed at the same height. , Since the foliage part was conveyed by rotating in the same plane at the same height and sandwiching the foliage between corresponding endless belts with conveying protrusions, the conveying passage should be narrowed by a certain amount or more due to the length of the conveying protrusions. If the endless belt with a transport projection does not have sufficient gripping force against the foliage, the foliage may slip off, or if the transport surface of the corresponding endless strip with a projection is approached to increase the gripping force, the transport projection will be removed. It has to be shortened, and as a result, there is a problem in that the transfer at the starting end of the carrying case cannot be carried out favorably, or the posture of the foliage part cannot be favorably changed at the time of discharging at the terminal end.

According to the present invention, even if the conveying surface of the endless belt with protrusions supported by the conveying case is brought close to the conveying passage and the conveying passage is narrowed, the conveying protrusion having the necessary length can be secured, and the gripping force against the foliage is sufficient. An object of the present invention is to provide a transfer device that can favorably take over at the start end and change the discharge attitude at the end.

(D) Means for Solving the Problem In order to achieve the above-mentioned object, in the foliage processing machine of the present invention, the foliage part of the rhizome-grown rhizome crop is scraped by a scraping device, and the scraping device is used. The squeezing and conveying device provided in the rear part of the squeezing device pulls out the foliage part, and the stalk and leaf part is conveyed to the upper rear part by the conveying device located in the rear part of the squeezing and conveying device. The left and right transport cases with endless belts with transport protrusions are provided in the rear part around the axis to form a transport device, and the left and right transport cases are arranged with upper and lower steps, and with the transport protrusions supported by the transport case. The end of the endless transfer protrusion is superposed on the corresponding transfer case.

Further, the drive shafts are arranged on the same line orthogonal to the machine traveling direction, the left and right transport cases are provided so as to be rotatable around the drive shafts, and the left and right transport cases are connected by a parallel link mechanism to rotate the left and right sides. It is dynamically fixed.

(E) Action In the transfer device in the foliage processing machine configured as described above, since the left and right transfer cases have step differences in the vertical direction, the left and right transfer endless belt transfer surfaces are brought close to each other to narrow the transfer passage. The gripping force on the foliage can be increased, and the foliage that is sandwiched between the left and right endless belts with transport protrusions is bent at the sandwiching part, and the endless strip with transport protrusions is engaged with the foliage. The holding power is increased and the fall of the foliage is prevented.

In addition, since the left and right endless transport protrusions with transport protrusions have a required length without being interfered with by the corresponding transport protrusions and the transport case, foliage can be favorably inherited at the start end of the transport passage. At the same time, it is possible to surely change the discharge attitude at the end portion.

Also, by rotating and fixing the transport case to the left and right by the parallel link mechanism, the discharge position is changed to the left and right, and the transport case on the discharge side is projected rearward. The posture can be changed reliably.
