Further, regarding the lug end trajectory of the take-up belt 47, the lower end portion is in the trajectory and the upper end portion is out of the trajectory with respect to the lug end trajectory of the horizontal lifting device 86, so that the stems and leaves such as vines can be surely harvested. To E. The lug retracting positions 86b and 81b are retracted earlier than the vertical lifting device 86 by the vertical lifting device 86, and the retracting operation position of the horizontal lifting device 86 is the lug of the take-up belt 47. Configure higher.

  The inclination angle of the vertical pulling device 81 and the horizontal lifting device 86 is such that the horizontal lifting device 86 is slanted as shown in the side view (a) and the main plan view (b) of FIG. This has the effect of separating the vines that are entangled, and by making the inclination of the scraping belt 47 looser than the horizontal lifting device 86, the leaves of the vines and the like entangled with the horizontal lifting device 86 are pulled apart and brought into the middle. be able to.

  By providing the inner cover 87 that connects between the inner ends of the cases of the vertical pulling device 81 and the horizontal lifting device 86, the scraped vines can be easily slipped inward. An outer cover 88 is extended to the rear of the horizontal lifting device 86 outside the vertical pulling device 81 so that the foliage of adjacent strips is not caught in the horizontal lifting device 86. The lower end of the inner cover 87 is triangular in order to obtain the effect at the lower end portion of the horizontal lifting device 86, and is gradually linearized upward.

  In the case of a double vertical configuration of the auxiliary raising device 81 and the raising device 42, as shown in the front view relation diagram (a) and the main part side view (b) in FIG. , 42 can incline toward the upper part so that the foliage that has been scraped up can be brought to the center of the ridge width. By configuring the inclination angle to be changeable by the handle H or the motor M, it is possible to adjust long stems and leaves according to the length of the stems and leaves with a small inclination and short stems and leaves as a large inclination. The turning point S of each inclination is close to the inclined case near the lower end, so that the deviation of the tip of the lug 81a can be reduced. Further, as shown in the front view relation diagram (a) and the main part side view (b) in FIG. 23, the outer left and right auxiliary pulling devices 81, 81 are configured to have variable inclination angles so that the entangled foliage The separability can be improved.

  In the above case, as shown in the front view relation diagram (a) and the main part side view (b) in FIG. 24, the inner pulling device 42 is more than the outer auxiliary pulling device 81 on the left and right sides. Short vines can be accommodated by shortening and tilting inwardly. The inclination angle is variable in front view.
