[Patent Document 1] Japanese Patent Application Laid-Open No. 2006-296344

When the sprinkling apparatus main body 42 reaches the stroke end part, the movement of the sprinkling liquid and the spreading apparatus main body 42 is temporarily stopped, and then the spreading of the fluid and the movement of the sprinkling apparatus main body 42 are started again. A series of operations to be described will be described based on FIG. 17.

As illustrated in FIG. 17A, the drive unit M rotates and drives the drive transmission unit 68 to one side via the drive sprocket 66 by the drive of the drive unit M, thereby engaging with the drive transmission unit 68. The part 39 is rotationally driven to spray the fluid from the feed port 49. The flow sprayed from the ejection opening 49 passes through the nozzle 50 and falls from the opening 50a of the nozzle 50. Moreover, by rotatingly driving the drive transmission part 68 to one side, the sprinkling apparatus main body 42 moves to one side (the right side of the paper of FIG. 17 (a)). As shown in FIG. 17B, when the spraying device main body 42 reaches the stroke end portion, the drive transmission unit 68 stops when the driving unit M stops, and the feeding unit 39 and the spraying unit are stopped. The apparatus main body 42 stops.

As illustrated in FIG. 17C, the drive unit M is rotated to drive the drive transmission unit 68 to the other side via the drive sprocket 66 by the drive of the drive unit M, thereby engaging with the drive transmission unit 68. The part 39 is rotationally driven to spray the fluid from the feed port 49. Moreover, by rotationally driving the drive transmission part 68 to the other side, the sprinkling apparatus main body 42 moves to the other side (the left side of the paper surface of FIG. 17 (c)). At this time, the fluid sprayed from the feeding port 49 may be in the middle of passing through the nozzle 50, and the fluid may not fall from the opening 50a of the nozzle 50. In this state, as shown in Fig. 17D, after a short time after the sprinkling apparatus main body 42 starts moving to the other side, the fluid sprayed from the ejection opening 49 is discharged from the nozzle ( It may be in the state which falls through the opening 50a of the nozzle 50 through 50.

As a result, as shown in FIGS. 17C and 17D, the spreading apparatus main body may move and the fluid may not drop. For this reason, since the unsprayed area | region d1 of a fluid may generate | occur | produce in the vicinity of the starting position of a spreading apparatus main body, there existed room for improvement in this point.

An object of the present invention is to provide a fluid sprinkling apparatus capable of supplying a fluid appropriately by eliminating the supply delay of the fluid.

The fluid spreading device of the present invention includes a spreading device main body having a spreading device for spraying a fluid, a transfer mechanism for reciprocating the spreading device main body, and the spreading device main body moving while spraying the fluid to the stroke end. When it arrives, it is provided with the control mechanism which drives the said spreading mechanism and the said transfer mechanism so that the spraying of a fluid and the movement of the said spreading apparatus main body may be temporarily stopped, The 1st characteristic structure stops at the said stroke edge part. When starting the spreading of a fluid and the movement of the spreading apparatus main body from a state, it is a point provided with the delay means which moves the said spreading apparatus main body for a predetermined time later from the start of spreading of a fluid.

According to the present invention, as shown, for example, in FIG. 16 (b), when the spraying device main body 42 reaches the stroke end portion, the driving unit M stops, whereby the spraying mechanism 46 and the spraying device The main body 42 stops.

As shown in FIG. 16C, when the spraying of the fluid by the spraying mechanism 46 and the movement of the spraying apparatus main body 42 are started, the spraying apparatus main body 42 is delayed by the TS. Delay the movement of by a predetermined time. For this reason, even if the spreading of the fluid by the spreading mechanism 46 is started, the spreading apparatus main body 42 is still stopped. After a predetermined time has passed since the start of spraying the fluid, the fluid has reached the site to be fed, such as a mat-like wool (see Fig. 16 (d)). At this time, the sprinkling apparatus main body 42 starts moving to another side.

In this way, since the spraying device main body is moved by a delay for a predetermined time from when the spraying of the fluid is started by the delay means, the timing at which the spraying device main body is moved and the timing at which the fluid actually falls and is supplied to the supply target site can be matched. have. As a result, the fluid can be appropriately supplied by eliminating the supply delay of the fluid and eliminating the occurrence of the unsprayed area of the fluid near the starting position of the sprinkling apparatus body.

When the control means 79 judges that the seedlings have been transferred and judges that the left end detection means 70 is in the detection state, the control means 79 sprays the medicine while spraying the medicine until the right end detection means 72 is in the detection state. Rightward sprinkling control for driving the electric motor M is performed to move the apparatus main body 42 to the right. When the control means 79 judges that the seedling transfer has been performed and judges that the right end detection means 72 is in the detection state, the control means 79 spreads the medicine while spraying the chemical until the left end detection means 70 becomes the detection state. In order to move the apparatus main body 42 to the left side, the left direction spraying control which drives the electric motor M is performed.

When the sprinkling apparatus main body 42 reaches the stroke end part, after stopping the movement of the chemical | medical agent spreading and the spreading apparatus main body 42 temporarily, the series which starts again the spraying of a chemical | medical agent and the movement of the spreading apparatus main body 42 again Will be described.

As shown in FIG. 16A, the roll drive is coupled to the endless chain 68 by rotationally driving the endless chain 68 to one side via the drive sprocket 66 by the drive of the electric motor M. FIG. The sprocket 55 is driven to rotate, and the medicine roll is sprayed from the feeding port 49 by the feeding roll 54. The chemical | medical agent sprayed from the discharge port 49 passes through the nozzle 50, and falls from the opening 50a of the nozzle 50. FIG. In addition, since the protruding pin 91 provided in the endless chain 68 is in contact with one contact member 69, by rotating the endless chain 68 to one side, the sprinkling apparatus main body 42 has one side (FIG. 16). In the direction of (a) to the ground]. As shown in FIG.16 (b), when the spreading apparatus main body 42 reaches the stroke edge part, the electric motor M temporarily stops by detection of the right end detection means 72, and an endless chain 68 temporarily stops, and the roll drive sprocket 55 and the feed roll 54 stop temporarily. In addition, the sprinkling apparatus main body 42 stops temporarily. At this time, the feeding pin 91 keeps in contact with one of the contact members 69.

As shown in FIG. 16 (c), the roll drive is coupled to the endless chain 68 by rotationally driving the endless chain 68 to the other side via the drive sprocket 66 by the drive of the electric motor M. FIG. The sprocket 55 is driven to rotate, and the medicine roll is sprayed from the feeding port 49 by the feeding roll 54. At this time, the protruding pin 91 is moving away from one contact member 69 to the other contact member 69 side, and the movement of the sprinkling apparatus main body 42 is still stopped. After a predetermined time has passed since the spraying of the chemicals, the chemicals sprayed from the dispensing port 49 pass through the nozzles 50 and fall from the opening 50a of the nozzle 50. At this time, when the protruding pin 91 provided in the endless chain 68 contacts the other contact member 69, the sprinkling apparatus main body 42 starts moving to the other side (refer FIG. 16 (d)). .

In this way, the movement time when the protruding pin 91 moves from one contact member 69 to the other contact member 69, and the chemical sprayed from the dispensing port 49 pass through the nozzle 50, and the nozzle By setting the time falling from the opening 50a of 50, the delay of supply of a chemical | medical agent can be eliminated, and the generation | occurrence | production of the unsprayed area | region d1 of a fluid can be eliminated in the vicinity of the starting position of the sprinkling apparatus main body 42. FIG.

Each jaw clutch (not shown) which cuts off the power of the feed case 20 from being transmitted to the mother transplant mechanism 23 is switched to a blocked state, the belt drive shaft 31 is stopped, and the mother implant apparatus 23 is stopped. ) And the seedling conveyance belt 30, the position detecting means (only the part corresponding to the remaining mother loading part 22a of the mother loading table 22 to reciprocate the sprinkling apparatus main body 42) On the basis of 75), partial spray control for driving the electric motor M may be performed.
