Also, the reel body 25 is configured to rotate in the direction of arrow A in FIGS. 4 and 5 by being transmitted to the pulley 39 that rotates integrally with the rotation shaft 22 of the reel body 25.

Each main scraping plate 2 in the reel body 25
As shown in FIGS. 3 to 5, a plurality of auxiliary scraping plates 40, such as three, are arranged in the longitudinal direction of the auxiliary scooping plate 40. It is attached so that it can move and adjust in each direction. As one example thereof, each main scraping plate 24 is provided with a mounting groove 41 elongated in the radial direction of the reel body 25, and bolts 42 fixed to both longitudinal ends of the auxiliary scraping plate 40 are mounted in the mounting groove 41. And then tighten with the nut 43.

As a result, in each main scraping plate 24 located on the lower side of the reel body 25, the ridge 3 is formed from the outer longitudinal edge of each auxiliary scraping plate 40 (the edge corresponding to the outside of the radius of the reel body 25). Height dimension H to the upper surface (Figs. 4 and 5
(See) can be changed depending on the widthwise portion of the ridge 3. The cutting means 44 shown in FIGS. 3 to 5 is formed to have a length substantially equal to the length of each auxiliary scraping plate 40, and each cutting means 44 corresponds to a division position of the auxiliary scraping plate 40. The height is adjustable so as to be close to the longitudinal edge of each auxiliary scraping plate 40.

As one example thereof, each cutting means 44 is
A heater 46 is attached to a metal cutting blade 45, and brackets 47, 47 are projected rearward from both left and right sides of the heater. A long mounting groove 48 is formed in each bracket 47, and a height of the mounting piece 50 is mounted via a bolt 51 to a mounting piece 50 protruding from a receiving gutter 49 that is open to the front of the machine frame 11 with respect to the screw conveyor 13. To do. Reference numeral 52 is a wiring for supplying electric power to each heater 46.

With the above structure, the traveling machine body 1 is arranged so as to straddle the ridges 3. At that time, depending on the height dimension H of the lower end (root of the flower pattern 10b) of the flower portion 10a of the tulip 10 that has been planted in a plurality of rows in the ridge 3, cutting with the auxiliary scraping plate 40 corresponding to that row. The height positions of both the means 44 and the means 44 are adjusted and fixed. Next, when the flower picking means 2 is driven while moving the traveling machine body 1 forward, the reel body 25 rotates in the direction of arrow A as shown in FIG. As a result, the flower part 10a is scraped toward the cutting means 44 one after another by the main scraping plate 24 radially arranged on the reel body 25 and the auxiliary scraping plate 40 near the outer periphery thereof. Then, when the outer peripheral long edge of the auxiliary scraping plate 40 approaches the cutting blade 45 of the cutting means 44, the floral pattern 10b is cut. At this time, since the cutting blade 45 is heated by the heater 46, the cut side of the root side of the flower pattern 10b that has been cut is heat-treated, and pathogens can be prevented from entering from this cut surface.

The cut flower portion 10a is carried out to the side of the traveling machine body 1 by the screw conveyor 13 at the location of the receiving gutter 49, then placed on the discharge conveyor 14 and carried out and collected in the storage basket 16. In this way, when the heights of the flower parts 10a of plants such as tulips that are planted in multiple rows on the ridges 3 are different, the mounting positions of the auxiliary scraping plates 40 divided in the longitudinal direction of the main scraping plate 24. By changing and adjusting the position of the cutting means 44 so as to be close to the longitudinal outer peripheral edge of the divided and position-adjusted auxiliary scraping plate 40, the cutting position is too high during the flower picking work. Part 10
It is possible to avoid such a situation that the middle portion of the height direction of a is cut, or conversely, the cutting portion is too low and the leaf portion is cut.

Incidentally, as in the above embodiment, the main scraping plate 2
Instead of forming the mounting groove 41 along the rotation radius direction of the reel body 25 on the fourth side, the mounting groove 41 is formed on both longitudinal ends of the auxiliary scraping plate 40, and the main scraping plate 24 and the bolt 42 are formed. The auxiliary scraping plate 40 may be mounted so that its position can be adjusted with the nut 43. In addition, in these embodiments, the longitudinal edge of the auxiliary scraping plate 40 can be mounted not only in parallel with the longitudinal edge of the main scraping plate 24 but also in an inclined shape, and each cutting means 44 can also be left and right. The height of the flower can be arranged in a slanted shape so that even if the height of the flower part of a plant with multiple rows is different in the slanted shape in the width direction of the traveling machine, the above-mentioned flower picking height Can be adjusted easily.

Further, one of the pair of left and right lift arms 9, 9 and the end portion of the machine frame 11 are arranged so that the entire machine frame 11 of the flower picking means 2 can be tilted in the width direction of the traveling machine body 1. Elevating means such as a hydraulic cylinder may be mounted between and.
