ターとを備えたものが提案されている。2. Description of the Related Art Conventionally, as a root crop harvester, for example,
As shown in Japanese Patent Publication No. 34575/1989, the root vegetable in the field is held between the left and right by a conveying belt (9 in the publication).
, Lifted and suspended and transported upward and backward, and the root portion of the root vegetable to be suspended and transported is inserted and guided between the left and right guide belts (10 in the publication) to align the height of the root vegetable main body. There has been proposed an apparatus provided with a positioning mechanism and a cutter that acts on a leaf portion of the root vegetable in a state where the height of the root vegetable body is aligned by the positioning mechanism.

るが、実用面では未だ不十分なものであった。The root crop harvesting machine having the above-described structure performs a leaf cutting process while continuously pulling up and transporting the root crop in the field while moving the machine forward along the row of root crops planted in the field. Although it can be expected to have an advantage that root vegetables can be efficiently harvested, it is still insufficient in practical use.

When a part of the leaves cannot be gripped between the belts and protrudes below the guide belt, the root vegetables are pulled up relative to the guide belt, and the root vegetable body is When the height is aligned on the lower surface, the protruding leaves are caught between the root vegetable body and the guide belt, and the root vegetable body does not approach the guide belt, resulting in poor alignment, or holding and transporting The leaves protruding from the belt are left uncut without being cut, and it is necessary to manually cut off the remaining leaves again, and the cutting performance in the leaf cutting process is low.

As a result, the cutter was disposed above the guide belt. As a result, the leaves will remain in the root vegetable body that has been subjected to leaf cutting, and if it is desired to obtain a root vegetable body having almost no leftover cutting residue, it will be left in the root vegetable body that has been mechanically harvested and collected. Leaves must be manually cut off again,
The root crop harvester will not be used effectively.

Detachment is less likely. As a result, when the root portion of the root vegetable that is suspended and conveyed is introduced between the left and right guide members in the alignment mechanism, a part of the leaf portion protrudes downward without being introduced between the left and right guide members. There is almost no possibility that the leaves are properly clamped by the nipping and pulling transport device, the leaves are properly guided by the alignment mechanism, and the leaves are moved between the root vegetable body and the guide member in the alignment mechanism. To avoid obstruction of height alignment, or to avoid uncut leaves that protrude downward.

Detachment is less likely. As a result, when the root portion of the root vegetables conveyed in a suspended manner is introduced between the left and right guide members in the alignment mechanism, a part of the leaf portion protrudes downward without being introduced between the left and right guide members. There is almost no chance that the leaves will be properly clamped by the nipping and lifting conveyance device, and the leaves will be appropriately guided by the alignment mechanism, so that the leaves will be between the root vegetable body and the guide member in the alignment mechanism. To avoid obstruction of the height alignment, or to avoid leaving uncut leaves protruding downward.

On the inner circumference of the left and right conveyor belts 11, there are pressed a number of rolling wheels 17 for pressing these in the direction in which they are present to generate a clamping force for the leaf portion Wb, and is positioned from the front end. Conveyor belt front 1 up to the start end of alignment mechanism B
In 1a, the strength of the spring 10a acting on the rolling wheel 17 is set so that a strong pinching force sufficient to pull out the underground root vegetables W is set, and in the rear side of the conveyor belt 11b on the rear side, A spring 10b that is thinner than the spring 10a is employed so that the holding force is weaker than the holding force at the front portion 11a of the transport belt.

The leaf Wb is pulled up by the locking claws 18 of the leaf pulling device 21 and guided between the left and right transport belt front portions 11a in the nipping and lifting transport device 9. Leaf Wb
Is pulled up by the left and right transport belt front portions 11a with a strong gripping force and lifted upward and rearward, the root vegetables W are pulled up from the field, and subsequently, the transport belt rear portion 11b in the gripping and pulling transport device 9 and the alignment mechanism B are aligned. Are transported rearward and upward.

The lower surface of B is approached, and the upper surface of the root vegetable main body Wa is guided by the rollers 14 of the guide member 12. Thereafter, due to the weak pinching force of the rear portion 11b of the conveyor belt, the rearward conveying force is transmitted to the root vegetables W and the relative slipping movement downward of the leaf portion Wb is allowed. Then
The root vegetable main body Wa is brought into a state in which the height is made uniform by the rollers 14 of the guide member 12, and in this state, the root vegetable W is delivered to the leaf cutting and holding apparatus A, and the cutter is secured with the aligned height. 3 is supplied.
