Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile harvester that cuts and harvests planted stems of sweet potato and the like as the machine moves.

Conventionally, in this type of mobile harvester, the stems cut by the reaping device are conveyed along a stem conveyance line that goes backward and diagonally upward from the root, and during this conveyance process, the leaves are removed by the defoliation device. At the same time, at the end of the conveyance, a cutting device cuts the stalks into a predetermined length. Furthermore, the strawberries mixed in the stalks are discharged outside the machine by a wind duct device, and the air-blown stalks are transported backward and upward by a lifting device. It is constructed so that it can be transported to the destination and placed on the loading platform of a truck or the like for storage.

The stem transport line is formed in a direction perpendicular to the inter-axle line connecting the axes of the support shafts of the pair of upper and lower feed rolls constituting the primary feeding device. As shown in Figure 5, the route 1 was formed to be located below the vertical center of the raking device, so when the cut stems were being transported later, the stems could hit the ground. The plant was transported after being washed, and when the plant was struck on the ground, pebbles etc. were inserted into the stem trunk.
There was a problem in that the cutting device was damaged by these pebbles and the like.

This invention was devised in view of the above-mentioned problems, and its purpose is to prevent the stem from hitting the ground, allowing it to be transported smoothly, thereby preventing damage to the cutting device. It is an object of the present invention to provide a mobile harvester that can prevent the above.

In order to achieve the above object, the present invention provides support for a pair of upper and lower feed rolls 3a and 3b that constitute the feed device 1 that feeds the stems that have been harvested and raked by the raking device 7 into the reaping processing cylinder. Axial centers Oa and Ob of shafts 5a and 5b
A stem transport route is provided at the upper end edge H of the raking device 7, and is formed diagonally upward rearward and perpendicular to the interaxial line S connecting the two.

Reference numeral 9 denotes the reaping processing WA 13 which is rotatably driven by a power transmission mechanism 121 comprising a sprocket, a chino, etc. provided on one side of the reaping processing barrel 13, and the reaping processing WA 13 has its lower rear end attached to the body frame 25 as a rotation fulcrum shaft. The fuselage frame 25 is supported so as to be movable up and down around the
A hydraulic cylinder is suspended between the reaping cylinder 13 and the reaping cylinder 13, and the reaping cylinder 13 is raised and lowered by operating the hydraulic cylinder 125.

The wind sorting device 19 is constructed by having a suction fan 129 rotatably housed in a dust exhaust pipe 127 connected to the terminal end of the reaping processing cylinder 13 and attached to the body frame 25.

The lifting device 21 includes a lifting cylinder 131 that has a base communicating with the lower part of the wind selection device 19 and extends toward the rear and upper side of the aircraft body.
An endless belt with lugs 133 is suspended inside.

In the above configuration, when the prime mover 27 rotates each rotating part of the machine body to move the machine forward and start work,
The fallen planted stem is raised by the pre-processing section 9, and the tip of the lifted stem is cut by the top cut device 11.
At the same time, the root portion is harvested by the reaping device 87 of the reaping section 15. This cut stem is scraped from the root by the scraping device 7, and processed along the stem transport line formed at the upper edge of the stem. It is fed into the feeding device 1 of 31117. The stem sent into the feeding device 1 is transferred to the defoliation device 7.
The stems are defoliated by 7, passed through a secondary feeding device 79, cut into stems of a predetermined size (usually about 30 cm) by a cutting device 81, and discharged from the terminal end of the cutting barrel 13. At this time, the stalks and trash are separated by the air sorting device 19, and the trash is discharged from the dust exhaust pipe 127 to the outside of the machine.

Then, the selected stems are transported to the rear and upper part of the machine body by the lifting device 21, and are discharged from the terminal end to the outside of the machine, and are fed into the loading platform of a truck or the like and stored therein.

In this way, the planted stems are reaped and harvested, and the present invention uses a pair of upper and lower feed rolls that constitute a feed device that feeds the cut stems that have been harvested and raked by the raking device to the reaping processing cylinder. The stem transport line, which is orthogonal to the inter-axle line connecting the axes of the support shafts and directed rearward and diagonally upward, is provided at the upper edge of the raking device. When the stems are raked up by the raking device and transferred to the feeding device for later transport, the stems are supported by the upper edge of the raking device, so they are not knocked against the ground and are transported smoothly. Ru. Therefore, the stem trunk does not pick up stones on the ground, and stones do not enter the processing barrel, making it possible to prevent damage to the processing barrel due to stones being mixed in.

In addition, FIG. 5 shows an explanatory side view of a mobile harvester equipped with a conventional stem transport line, and the same reference numerals as in FIGS. 1 to 4 indicate the same components.

Further, the present invention is not limited to the above-described embodiments, and the present invention can be implemented in modes other than the above-described embodiments.

Further, although reference numerals are written in the claims for convenience of comparison with the drawings, the reference numerals do not limit the technical scope of the present invention.
