A first electric motor 23 that is a first driving body to be driven, and a second electric motor 24 that is connected to the outer end side of the second rotating shaft 22 and rotates the second rotating shaft 22. .

  The first rotating shaft 21 is horizontally disposed so as to penetrate through the two rotating body accommodating portions 15 of the first accommodating body 13, and is located at two locations within the rotating body accommodating portion 15 of the first rotating shaft 21. In this portion, there are provided first feeding rotary bodies (feeding rolls) 26 that rotate together with the first rotating shaft 21 and feed the objects to be scattered in the first housing body 13 of the housing means 11 by a predetermined amount. The second rotating shaft 22 is horizontally disposed so as to penetrate the two rotating body accommodating portions 15 of the second accommodating body 14, and is located in the rotating body accommodating portion 15 of the second rotating shaft 22.

Yes.

  In addition, the 1st delivery rotary body 26 and the 2nd delivery rotary body 27 are rotatably arrange | positioned in the rotary body accommodating part 15 of the accommodating means 11, and the some to-be-spread material, such as a fertilizer, enters into the outer peripheral surface part. Recesses 28 are formed at intervals in the circumferential direction (see FIG. 3).

  Further, the feeding means 12 is in a connected state when the first electric motor 23 and the second electric motor 24 are operated, connects the first rotating shaft 21 and the second rotating shaft 22, and is in a non-connected state. A connecting means 31 for releasing the connection between the rotating shaft 21 and the second rotating shaft 22 is provided. The connecting means 31 can be selectively switched between a connected state and a non-connected state by rotating the operation lever 32.

  As shown in FIGS. 4 (a) and 4 (b), the connecting means 31 is, for example, an inner end portion that is an opposite end portion of the first rotating shaft 21 and an opposite end portion of the second rotating shaft 22 in the connected state.
