That is, by operating this operating means 52, the rotational speed of the first rotating body 12 and the rotating speed of the second rotating body 32 can be individually adjusted. Note that the operating means 52 is disposed at a position where an operator on the tractor can operate, for example.

  Next, the spraying work by the spraying device 1 will be described.

  First, the same kind of objects to be dispersed are accommodated in the first container 11 of the first working part 3 in the center and the second containers 31 of the two second working parts 4 on the left and right sides. A case where an object is dispersed is described.

  When working at the maximum working width, the two left and right second working parts 4 are turned 180 degrees in the deploying direction with respect to the first working part 3 about the turning fulcrum shaft 5 to be in a protruding state. Switch.

  Further, the rotational speed of the first rotating body 12 of the first working unit 3 and the rotational speed of the second rotating body 32 of both the second working units 4 are set to the same speed.

  And if the spreading | diffusion apparatus 1 whole is moved ahead by driving | running | working of a tractor, the 1st rotary body 12 of the 1st working part 3 and the 2nd rotary body 32 of both the 2nd working parts 4 which are the protrusion states will be the same. Rotating at a speed, a desired amount of material to be spread is evenly spread over the field.

  For example, only one of the two second working parts 4 is rotated 180 degrees in the folding direction so as to be in a non-projecting state, and the first working part 3 and the other of the two second working parts 4 are sprayed. It is also possible to rotate both the second working parts 4 180 degrees in the folding direction so as to be in a non-projecting state, and to perform the spraying work only with the first working part 3.

  Next, different types of objects to be scattered are separately accommodated in the first container 11 of the first one working unit 3 in the center and the second containers 31 of the two second working units 4 on the left and right sides. The case where the work of spraying the objects to be sprayed is described.

  That is, for example, as shown in FIG. 5, a powdered object (powdered fertilizer A) is accommodated in the first container 11 of the first one working unit 3 at the center, and both the left and right second work A granular object (granular fertilizer B) is accommodated in the second container 31 of the section 4.

  Then, the two left and right second working parts 4 are turned 180 degrees in the folding direction about the turning fulcrum shaft 5 with respect to the first working part 3 and switched to the non-projecting state.

  Further, the rotational speed of the first rotating body 12 of the first working unit 3 and the rotational speed of the second rotating body 32 of both the second working units 4 are set to different speeds. That is, for example, the set speed value of the first rotating body 12 of the first working unit 3 is set to a value larger than the set speed value of the rotating speed of the second rotating body 32 of the second working units 4.

  Then, when the entire spreading device 1 is moved forward by the traveling of the tractor, the first rotating body 12 of the first working part 3 and the second rotating bodies 32 of the second working parts 4 that are in the non-projecting state, Each of them rotates at a different speed, whereby a large amount of powdery material to be scattered is sprayed on the field, and at the same time, a small amount of granular material is sprayed on the field.

  In addition, for example, when spraying the same amount of the powdery object and the granular object, the rotational speed of the first rotating body 12 of the first working unit 3 and the second rotation of both the second working units 4 are used. The rotational speed of the body 32 may be set to the same speed.

  And according to such a spreading | diffusion apparatus 1, since both the 2nd working parts 4 on either side can carry out a spreading | diffusion work in any of the time of a protrusion state and a non-protrusion state, each 2nd operation | work The spraying operation can be performed not only when the part 4 is in the protruding state but also in the non-projecting state, and thus, for example, it is possible to efficiently perform the spraying operation of different types of scattered objects without mixing two different types of scattered objects. it can.

  Further, each second working unit 4 can be appropriately protruded by rotating it 180 degrees in one direction with respect to the first working unit 3. By rotating 180 degrees in the direction, it can be appropriately brought into a non-protruding state, so that, for example, when not working, the width of the spraying device 1 can be reduced, and the spraying device 1 can be transported easily and safely to a warehouse or the like. it can.

  Furthermore, since the first working unit 3 has the first driving means 13 for performing the spraying work, and each of the second working parts 4 has the second driving means 33 for performing the spraying work, A desired spraying operation can be performed appropriately.

  Moreover, since the rotational speed of the 1st rotary body 12 of the 1st working part 3 and the rotational speed of the 2nd rotary body 32 of the 2nd working part 4 can be adjusted separately, respectively, the spreading amount of to-be-spread material can be set. Desired spraying operations can be performed more appropriately, such as different types.
