Sent to 3 side. The rotational speed of the rotating body 21 can be adjusted steplessly by controlling the electric motor 25.

  Furthermore, the spraying device 1 is in an open state to open the spraying hole 3 of the scattered object container 2 and to be closed to close the spraying hole 3 of the sprayed object container 2. An opening / closing body 31 and an opening / closing body driving means 32 for opening and closing the opening / closing body 31 are provided.

  The opening / closing body 31 is in contact with the lower surface of the spraying amount adjusting shutter 5 and closes the spraying hole 3 of the object container 2 to be opened / closed in the left / right direction and made of synthetic resin such as urethane having a curved plate shape. A pair of left and right plate portions 33 are provided.

  Further, the spraying device 1 is provided with a control means 41 for controlling the rotating body driving means 22 and the opening / closing body driving means 32. As shown in FIG. The driving means 32 and the lid detection means 13 are electrically connected.

  Then, at the start of the spraying operation, based on the control of the control means 41, the drive of the electric motor 25 of the rotating body drive means 22 after the open / close body 31 is opened by the drive of the electric motor 38 of the open / close body drive means 32 As a result, the rotating body 21 rotates in a predetermined direction. At this time, the control means 41 drives the electric motor 25 of the rotating body driving means 22 only when the object supply port 11 of the object storage body 2 is closed by the lid 12. Further, when the spraying operation is stopped, based on the control of the control means 41, after the rotating body 21 is stopped by stopping the electric motor 25 of the rotating body driving means 22, the opening / closing body is driven by the electric motor 38 of the opening / closing body driving means 32. 31 is closed.

  Next, the operation and the like of the above embodiment will be described.

  When the spraying device 1 is used for spraying, the cover 12 is opened to open the sprinkler input port 11, and the spatter is received from the sprinkled spatter input 11. Put it in the body 2. After throwing in the object to be sprinkled, the lid 12 is closed and the sprinkling object inlet 11 is closed.

  Then, when the entire spraying device 1 is moved forward by the traveling of the tractor T, when the operation start button of the operation means such as a remote controller (not shown) is pressed, the opening / closing body drive means 32 is electrically controlled by the control means 41. The motor 38 is driven, the opening / closing body 31 is changed from the closed state to the open state, and the spray hole 3 is opened.

  Thereafter, under the control of the control means 41, the electric motor 25 of the rotator driving means 22 is driven, and the rotator 21 slows up and rotates. And the to-be-spread object in the to-be-sprayed object container 2 is sent to the sprinkling hole 3 side while being agitated by the rotation of the rotating body 21, and falls from the sprinkling hole 3 opened.

  Note that the control means 41 drives the electric motor 25 of the rotating body driving means 22 only when the object supply port 11 of the object storage body 2 is closed by the lid 12. That is, only when the lid body detection means 13 detects that the lid body 12 is in the closed state, the control means 41 drives the electric motor 25 to rotate the rotating body 21. For this reason, the rotating body 21 is not rotated by the drive of the electric motor 25 in the state where the sprinkling object inlet 11 is opened.

  Further, when stopping the spraying work, for example, when a work stop button of an operating means such as a remote controller (not shown) is pressed, the electric motor 25 of the rotating body driving means 22 is stopped and the rotating body 21 is slowed down by the control of the control means 41. Down and stop. Thereafter, under the control of the control means 41, the electric motor 38 of the opening / closing body driving means 32 is driven, and the opening / closing body 31 is changed from the open state to the closed state.

  Thus, according to the spraying device 1, since the control means 41 for controlling the electric motor 25 of the rotating body driving means 22 according to the state of the opening / closing body 31 is provided, the opening / closing body 31 is opened and the spraying hole When 3 is opened, a large amount of objects to be dispersed do not fall onto the field at once, and the objects to be dispersed can be evenly dispersed.

  Further, since the control means 41 drives the electric motor 25 of the rotating body driving means 22 only when the spattering object inlet 11 is closed by the lid 12, the spattering object inlet 11 is opened. The rotating body 21 is not rotated by the drive of the electric motor 25 in the state, and the safety is excellent.

  In the above-described embodiment, the lid body detecting means 13 for detecting the state of the lid body 12 is provided, and the control means 41 is rotated only when the scattered object inlet 11 is closed by the lid body 12. The configuration for driving the body driving means 22 has been described. For example, as shown in FIG. 6, an optical system sensor or the like that detects an intruding object from the spattering object inlet 11 into the sprinkled object container 2. Even if the object detecting means 45 is provided and the control means 41 stops the rotating body driving means 22 when the entering object is detected by the entering object detecting means 45, the safety can be improved.

  Further, the rotating body driving means 22 may be constituted by, for example, a hydraulic motor other than the electric motor 25. Similarly, the opening / closing body driving means 32 may be constituted by, for example, a hydraulic motor other than the electric motor 38. .

  Furthermore, it is not limited to the configuration in which the opening / closing body 31 is opened and closed by the power from the opening / closing body driving means 32, and a configuration in which the state of the opening / closing body 31 is switched manually is also possible. In this case, for example, the control means 41 drives the rotating body driving means 22 on condition that the opening / closing body 31 is in the open state.

  Further, for example, it is provided with an overload detecting means for detecting that a load greater than a predetermined value is applied to the rotating body driving means 22, and the control means 41 stops the rotating body driving means 22 based on the detection of the overload detecting means. It is good.

  Furthermore, the configuration is not limited to the configuration in which the opening / closing body 31 is closed after the rotating body 21 is stopped by the control of the control means 41 when the spraying operation is stopped, depending on the type of the object to be sprayed. After the opening / closing body 31 is in the open state, the rotating body 21 in the low-speed rotation state rotates at an appropriate rotation speed corresponding to the spraying work, and when the spraying work is stopped, the rotating body 21 is appropriate for the spraying work. The opening / closing body 31 may be in a closed state after a low-speed rotation state in which the rotation speed is lower than the rotation speed. For example, when the spread material is a fertilizer or the like that is relatively easy to collect, the spread material can be prevented from clumping by always rotating the rotating body 21 at a low speed when the opening / closing body 31 is closed. Even if the rotating body 21 rotates at a low speed when the opening / closing body 31 is closed, the object to be sprayed is not clogged between the opening / closing body 31 and the rotating body 21 in the closed state.
