As described above, the first endless belt 8 and the second
One of the end portions of the endless belt 9 (the first endless belt 8 in this embodiment) protrudes forward because it grips the agricultural product B such as radish vegetated in the field and pulls it out of the field. This is to improve the pinchability when harvesting.
The reason for this step difference is that, as in the conventional example shown in FIG. 3, when the end portions of the first endless belt 8 and the second endless belt 9 are aligned, the pinchability of the agricultural product B vegetated in the field is reduced. This is because the cross section of the first endless belt 8 (and the second endless belt 9) had to be made a special stepped belt as shown in FIG. And by making it uneven, the pinch of agricultural products B is improved,
The first endless belt 8 and the second endless belt 9 may be flat belts.

FIG. 3 shows that the harvesting / transporting belt 11 is constituted by the three endless belts of the first endless belt 8, the second endless belt 9, and the third endless belt 10 as described above. As shown in the figure, the first endless belt 8 and the second endless belt 9 are moved to the second endless belt
Crop HB on the horizontal transport path of the third endless belt 10
A gap is formed at the position where the harvested agricultural products HB are delivered and transferred, and the harvested agricultural products HB are not smoothly delivered and transferred, and in some cases, fall. Therefore, in the present invention, the holding wheels 17 and 18 made of a pair of sponge-like elastic rolls are arranged at the gap positions. The transfer holding wheel 17 is supported so as to be driven coaxially with the drive pulley 9c, and is brought close to the outer peripheral surface thereof so that the outer peripheral surface of the transfer holding wheel 18 comes into contact with the driving pulley 9c. It is also possible to forcibly drive the holding wheel 18 for transfer.

As described above, according to the pulling and conveying mechanism of the agricultural product harvesting apparatus of the present invention, the following effects can be obtained. . The pull-out transport mechanism transports the pair of endless belts 8 and 9
The front pulleys 8a, 9a and the rear end pulleys 8b, 9c are stretched so as to rotate inward each other, and the front end withdrawn portion is substantially the same as the diameter of the front side pulleys 8a, 9a. Since the belts are shifted back and forth, the end portions of the endless belts 8 and 9 allow the agricultural products B vegetated in the field to bite easily and can be easily pulled out, so that the transport belts 8 and 9 do not need to be special belts. . . The transport belts 8 and 9 in the vertical direction are rear pulleys 8b and 9
c, the start-side pulley 10a and the end-side pulley 1 are opposed to the horizontal end of the transfer belt 9 stretched between the rear-end side pulley 9c and the end-side pulley 9b.
0b is provided, and the biting portion of the horizontal conveying belt 10 on the side of the starting pulley 10a is
Since the transport belt 9 is disposed so as to be shifted from the start end of the horizontal transport portion of the transport belt 9 to a position corresponding to the rear end pulley 8b of the vertical transport belt 8, the horizontal transport belt is moved from the transport end portion of the vertical transport belts 8, 9 to the horizontal transport belt. Delivery and transfer of the harvested agricultural products HB to and from the 9, 9 are smoothly performed, and the harvested agricultural products HB do not fall off the horizontal transport belts 9 and 10.
