Accordingly, when the crops are cut by the cutting edges 124, the upper portions of the cut crops are gripped by the serrated sprockets 132c of the rotating plates 132a rotating at the upper portions of the cutting edges 124, And guided sequentially between the pair of conveyance belts 134.

 1, the conveying guides 132b are installed near the rotation plate 132a and extend toward the outside of the rotation plate 132a about the rotation axis of the rotation plate 132a. For example, the conveying guides 132b are attached to the upper end or the lower end of the rotating body 132 and are formed in a long blade shape extending toward the outside of the rotating plate 132a about the rotating axis of the rotating plate 132a, Accordingly, the rotation plate 132a can have elasticity with respect to the center of the rotation plate 132a. Accordingly, the crop can enter the conveying belts 134 more effectively along the conveying guides 132b.

The rotational power of the rotation plate 132a may be transmitted from a roller module that circulates the conveyance belts 134. [

Each of the conveyance belts 134 and the pair of roller modules may be disposed side by side, for example, as shown in FIG.

The pair of conveyance belts 134 press the cut crops between the front side of the body 110 and the front side of the body 110 when the cutter 130 guides the cut crops, And they may be arranged to be twisted to each other so as to face each other in a direction perpendicular to each other at the rear of the vehicle body 110 in the front of the vehicle body 110 in a horizontal direction.

A plurality of protrusions (not shown) may be formed on the surfaces of the conveyor belts 134. Accordingly, the crop can be effectively squeezed so that the crop located between the conveyance belts 134 does not slip.

The pair of roller modules supports each of the conveyance belts 134 and rotates to generate a circulation operation of the conveyance belt 134.

Each of the roller modules includes a traveling roller 136 for transmitting power to each of the conveyance belts 134 horizontally in the rear of the vehicle body 110 and a driving roller 136 for transmitting power to the traveling roller 136 in front of the vehicle body 110. [ And guide rollers 138 installed vertically at lower positions relative to the conveyor belt 134 to support and guide the conveyor belt 134. In addition, the guide roller 138 may transmit power to the rotating body 132. By this arrangement, the conveyance belt 134 is arranged in a twisted manner. Therefore, crops upright in the pre-loading section 120 are guided by the rotation plate 132a between the pair of conveyance belts 134, and the crop is conveyed by the conveyance belts 134 to the body Can be conveyed to have a lying form at the rear of the body 110.

Meanwhile, the guide rollers 138 may include a front guide roller 138a and a rear guide roller 138b. The guide rollers 138 are installed in front of the vehicle body 110 to support and guide the conveyor belts 134. 2, the front guide roller 138a is disposed in front of the rotating body 132, and the rear guide roller 138b is disposed behind the rotating body 132. As shown in FIG.
