[0008]

Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a potato harvester. The potato harvester 1 is a crawler (a pair of left and right pairs) on both left and right sides of a body 2 extending in the front-rear direction, and capable of spinning (super-spot). Traveling equipment)
Equipped with 3,3. The machine body 2 is provided with a digging conveyor device 4 for digging agricultural products in a field and transporting the farm products rearward from a lower front portion thereof to a rear upper portion of the machine body 2 through a central upper portion of the machine body 2.

In the excavating conveyor device 4, a harvest ridge following device 6 is attached to a front upper side via a support arm 5,
The front portion 7 of the excavating conveyor device 4 including the harvest ridge following device 6 can be folded upward by operating a hydraulic cylinder (not shown). At the rear end of the excavating conveyor device 4, a support frame 8 for mounting a light (not shown), a container mounting table for mounting an empty container, and the like is provided so as to protrude upward. The rear part 9 of the excavating conveyor device 4 including the support frame 8 is rotatable toward the front with the vicinity of the folded position of the front part 7 as a fulcrum. When the rear part 9 is turned or the front part 7 is folded, the support arm 5 and the support frame 8 can be connected.

The digging conveyor device 4 has a digging blade 12 at the tip between a pair of left and right lower side frames 10 and an upper side frame 11, and is connected to the digging blade 12.
A rod conveyor 13 composed of endless link rods and provided with slats at predetermined intervals is wound thereon. The rear end of the lower frame 10 and the front end of the upper frame 11 are pivoted via pivot points 15 and 16 with respect to a pair of left and right support plates 14 erected at the front of the body 2. As described above, the front part 7 of the excavating conveyor device 4 can be folded upward, and the rear part 9 is rotatable forward. The upper frame 11 is always fixed to the body 2 side of the rear portion 9, and the fixing is released only when the rear portion 9 is rotated to the front side.

An engine (not shown) is mounted near the left and right sides of substantially the center of the body 2, and an engine is mounted on the front side thereof.
A hydraulic pump driven by the engine is mounted. Further, a transmission is provided between the crawlers 3 and 3 at a lower position near the front of the body 2. On one side of the body 2 on the rear side of the engine, an operation unit for operating the body and operating the drive unit is provided. A substantially horizontal sorting / conveying device 17 is provided continuously to the transport end of the excavating / conveying device 4.

The transmission which receives power from the engine and shifts is provided with a continuously variable hydraulic transmission (HST) which continuously changes the speed so that the transmission can be continuously and continuously shifted in combination with a transmission gear. The power transmission is connected / disconnected via a side clutch and a differential device to allow the crawlers 3 and 3 to travel steplessly and stepwise, and to enable spin turning (super turning). Also,
The speed-changed power is transmitted from the transmission to the excavating conveyor device 4, and the speed of movement of the rod conveyor 13 can be adjusted between stepless and stepped. By combining with step running, the digging work speed can be set freely.

A number of members such as the transmission, the HST, and control members such as rods and wires are disposed below the rear portion 9 of the excavating conveyor device 4, respectively. In a fixed state, it is difficult to perform maintenance such as adjustment, maintenance, repair, and replacement. The harvesting ridge following device 6 is provided with a pair of wheels that are in contact with the inclined shoulders of the ridge to be harvested so as to be opposed to the left and right sides. I support it.
The pair of wheels have a camber angle, rotate in contact with both inclined shoulders of the ridge to be harvested, and steer and move the body following the ridge to be harvested.

Next, the operation of the peach harvester 1 constructed as described above will be described. When harvesting root crops such as sweet potatoes, potatoes, onions, beets, taro, konjac potatoes, short root ginseng, and raccoon from the field, for example, the potato harvester 1 is configured to use the harvest row follower 6 in the state shown in FIG. Of the ridge to be harvested, and the digging blade 12 of the digging conveyor device 4 is vertically moved to adjust the digging depth. The excavation is carried out by 12 and the rod is conveyed with the soil by a rod conveyor 13 and lifted obliquely upward. During this transport,
The soil falls from between the link rods, and the harvest is sent to the sorting conveyor device 17, where it is sorted and stored in a container (not shown).

When the potato harvester 1 reaches the end of the field during the agricultural product harvesting operation and turns to move to the next work ridge, the hydraulic cylinder is operated to excavate as shown in FIG. The front part 7 of the conveyor device 4 is turned around the turning fulcrum 15 to be folded upward, thereby shortening the overall length of the body and performing headland turning with a small area. In addition, when the potato harvester 1 is loaded on a transport vehicle and transported, or stored in a warehouse or the like, the entire length of the fuselage is shortened by folding the front portion 7 of the excavating conveyor device 4 in the same manner. hand,
As shown in FIG. 3, the support arm 5 and the support frame 8 are connected. By this connection, the front portion 7 is stably supported.

When it is necessary to perform maintenance on the transmission, HST, control members such as rods and wires, etc. disposed below the rear part 9 of the excavating conveyor device 4, the rear part 9 is removed. It can be pivoted forward about the pivot point 16 to be fully open, and maintenance of the transmission, the HST, and control members such as rods and wires can be easily performed. If necessary, the support frame 8 and the support arm 5 are connected as shown in FIG. By this connection, the rear portion 9 is stably supported, and maintenance can be performed safely.

[0017]

As described above, according to the agricultural product harvester of the present invention, the following effects can be obtained.

[0018] Since the rear part of the digging conveyor device is configured to be rotatable toward the front side with the vicinity of the folding position of the front part as a fulcrum, the transmission, HST, rod, wire, etc. arranged below the rear part When it is necessary to perform maintenance such as control members for
The rear portion is rotated to the front side to be fully open, and these maintenances can be easily performed.

[0019] Provide a support frame projecting upward at the rear end of the rear portion of the digging conveyor device, when folding the front portion of the digging conveyor device, or when rotating the rear portion of the digging conveyor device, Since the support arm and the support frame of the harvest ridge following device were connected and supported, the front portion of the digging conveyor device was folded, or the rear portion of the digging conveyor device was rotated forward. In this state, the support arm and the support frame are connected to each other and can be supported stably.
