Since 7a is fixed to the scraper drive device 26 and is immovable,
The scraper 28a itself moves downward along the vertical sliding groove 36. Conversely, when the hydraulic jack 41 is retracted as shown by arrow C, the scraper 28a itself moves upward along the vertical sliding groove 36 due to the same effect as described above. In this way, the height position of the scraper 28a relative to the vehicle body 4 can be changed. When the 0 or more scrapers 28a move up and down, the telescopic rotary wheel 29a expands and contracts, and the universal joint (33) attached to both ends thereof expands and contracts. As the .45 moves up and down,
Even if the positional relationship between the scraper drive device 26 and the rotation shaft of the scraper 29a changes due to the vertical movement of the scraper 28a, power can be transmitted from the scraper drive device 26 to the rotation shaft of the scraper 29a. 0Next, if it is necessary to change the interval between the raking machines 28a and 28b arranged on the left and right sides depending on the state of reproduction of the mulberry leaves to be harvested, the poles 40 attached to the connecting body 38 may be changed. When loosened, the main body of the scraper 28a can be manually moved along the horizontal sliding groove 39 provided in the connecting body 38 as shown by the arrow in FIG. the result,
Since the raking machines 1!2aa and 28b can be moved to the left and right, the interval between the raking machines 28a and 28b can be set to an arbitrary width. Furthermore, as shown in Figure 8, in conventional row mulberry reapers, the vehicle body tilts according to the inclination of the slope, so the driver, who is seated in the driver's seat at the top of the vehicle body, is constantly concerned about the possibility of the vehicle tipping over on the slope. I had some concerns, but as shown in Fig. 7, this row mulberry reaper is equipped with hydraulic pressure adjusters 2a, 2b, 3a, and 3b on the tracked vehicles 1a and lb.
/ki15a.

15b, 16a, and 16b can be operated from the driver's seat 25 to extend and contract, thereby making the vehicle body 4 horizontal.

(Effects of the Invention) In the present invention, by configuring the row mulberry reaper as described above, the raking machine can freely move vertically and horizontally with respect to the vehicle body. As a result, the mulberry can be harvested at any height, and even if the mulberry has fallen down, the raking device of the raking device can be moved downward to guide the mulberry to the reaping device and harvest it. It has excellent effects.
