Next, the mechanism for connecting and disconnecting the spout 105 and the socket 102 described above will be described with reference to FIGS.
Will be explained. Incidentally, FIG. 5 shows the outer cylinder 1 of the spout 105.
6 shows a state in which the outlets 12 and 21 of the inner cylinder 2 are closed, and FIG. 6 shows a state in which they are opened.

When connecting the spout 105 and the socket 102, first, the cap 3 (see FIGS. 1 and 2) on the spout 105 side is removed, and the outlet 12 and the outlet of the outer cylinder 1 and the inner cylinder 2 of the spout 105 are removed. The outer cylinder 1 is housed in the connecting cylinder 6 and the inner cylinder engaging portion 2 is in a state in which 21 is not communicating.
The connector rod 5 is stored in the inner cylinder 2 so that the rod 2 and the rod engaging portion 54 are engaged with each other. Then, the lower end portion of the outer cylinder 1 is inserted until just before hitting the upper surface of the rod flange 51, and comes into contact with the O-ring 56.

In this state, the lower flange 14 of the outer cylinder 1 is in a position immediately before contacting the seat portion 76 of the connector lid 7, and contacts the release projection 83 provided on the upper edge of the handle cylinder portion 81. . Further, although the upper end of the outer cylinder locking projection 13 and the lower end of the connecting cylinder locking projection 65 are at substantially the same height, they are displaced in the circumferential direction.

Subsequently, the handle lever 84 of the connector handle 8 is rotated counterclockwise from the position shown in FIG.
Rotate the connecting tube 6 and the connector rod 5.

At this time, as the connecting cylinder 6 rotates, the connecting cylinder locking projection 65 moves in the circumferential direction, so that the connecting cylinder locking projection 65.
Can be located on the outer cylinder locking projection 13. That is, by rotating the connector handle 8 to a predetermined position, the outer cylinder locking projection 13 is engaged by the connecting cylinder locking projection 65 that interlocks with the connector handle 8, and the spout 105 is locked while being pulled toward the socket 102 side. And socket 102

That is, as described below, in this state, the spout 105 has the outlets 12 and 21 open.
Since the spout 105 cannot be removed from the socket 102 when the outlets 12 and 21 of the spout 105 are opened, the leakage of the chemical liquid due to accidentally removing the chemical liquid container with the outlets 12 and 21 opened is prevented. can do.

On the other hand, the rod engaging portion 54 and the inner cylinder engaging portion 22.
Are engaged with each other, and the lower flange 14 of the outer cylinder 1 is abutted against the seat portion 76 of the connector lid 7, so that the outer cylinder 1 does not rotate as the connector rod 5 rotates, The inner cylinder 2 rotates in the outer cylinder 1. That is, by rotating the connector handle 8 to a predetermined position, the outlets 12 and 21 of the outer cylinder 1 and the inner cylinder 2 are aligned with each other and can be opened. As a result, the drug solution in the drug solution container passes through the inner cylinder 2, the connector rod 5, and the drug solution supply port 42 and is supplied to the drug solution sprayer main body 101 side.

In the present embodiment, the inner cylinder engaging portion 22 has a convex shape and the rod engaging portion 54 has a concave shape. However, a combination opposite to this may be used, and these can be easily and surely. The shape is not particularly limited as long as it is a combination that can be engaged with.

When the connection between the spout 105 and the socket 102 is released, the connector handle 8 is rotated clockwise to the original position so that the connecting cylinder locking projection 65 is released.
The locking of the outer cylinder locking projection 13 due to is released, the entire spout 105 is pushed up from the socket 102 side, and finally, the release projection 83 on the upper edge of the handle tubular portion 81.
Release is completed by. At the same time, the outlets 12 and 21 of the outer cylinder 1 and the inner cylinder 2 are displaced and closed, and the supply of the chemical solution is stopped.

As described above, when the spout 105 is pulled out from the socket 102, the outlet 12 and the outlet 21 of the outer cylinder 1 and the inner cylinder 2 are always closed. Even if the chemical solution container is accidentally removed, the chemical solution does not leak.

The outlets 12 and 21 do not necessarily need to be open when the spout 105 cannot be pulled out from the socket 102. However, in order to obtain the above effect, when the outlets 12 and 21 are opened. It is always preferable to be in the pull-out prevention state.

Whether or not the spout 105 is pulled out and whether or not the outlets 12 and 21 are opened are provided with marks corresponding to, for example, the lid base 71 of the connector lid 7 or the chemical solution container body 101. It is preferable that the connector handle 8 can be surely adjusted by providing an engaging portion for restricting the rotation of the connector handle 8 within a predetermined range to give a click feeling. .

Further, in the configuration of this embodiment, the spout 10
After the pulling-out prevention of 5 is released, the connector handle 8 is further rotated in this releasing direction to push up the lower flange 14 of the outer cylinder 1 by the release protrusion 83 of the connector handle 8 having an inclined portion, which facilitates the operation. Then, the spout 105 can be pulled out.

That is, after the pullout prevention of the spout 105 is released, the outer cylinder 1 is pushed up to seal the inner peripheral portion of the outer cylinder 1 and the outer peripheral portion of the rod upper cylindrical portion 53.
The spout 105 can be released from the close contact state by
Is preferable because it can be easily pulled out from the socket 102.

Next, one embodiment of the chemical liquid spraying machine of the present invention will be described with reference to FIG.

In FIG. 7, 101 is the main body of the chemical spraying machine,
Reference numeral 102 is a socket, 103 is an injection nozzle, 104 is a chemical liquid container body, and 105 is a spout.

The socket 102 and the spout 105 are as shown in FIGS.

Although not shown in the figure, the sprayer main body 101 is provided with a spray pump and a battery, and the spray nozzle 103 is provided with the chemical liquid in the mounted chemical liquid container main body 104 to operate the spray pump. It is supposed to be ejected from. Further, although the illustrated spreader main body 101 is of a backpack type, a shoulder type, a handheld type,
Further, it may be of a stationary type.

It is also possible to use an IB (back in box). It is also preferable to use a biodegradable synthetic resin in order to facilitate waste disposal.

When BIB is used as the chemical solution container, the synthetic resin sheet bag is deflated and the pressure inside the bag is adjusted as the chemical solution is consumed, so that the chemical solution is consumed as in the case where a hard container is used. At the same time, there is an advantage that an intake port with a check valve that allows air to enter the container is not required. In the case of BIB, it is preferable that the spout 105 has a structure protruding from the box in a state in which the spout 105 is hard to move in order to facilitate mounting on the socket 102.

In the embodiment shown above, the upper flange 11, the lower flange 14 and the rib 15 of the spout 105 can be made to perform this function. That is, the vertical movement of the spout 105 is suppressed by the upper surface of the lower flange 14 or the lower surface of the upper flange 11 hitting the bottom surface of the box, and the rotation of the spout 105 is suppressed by the rib 15 hitting the cut surface of the box. You can In the case of BIB, since it is difficult to check the remaining amount of the liquid medicine in the inner bag, it is preferable to provide a cut groove for confirming the remaining amount on the front surface of the outer box.

The chemical solution container body 104 is preferably made of a transparent synthetic resin, for example, so that the residual quantity of the chemical solution can be seen from the outside, and it is more convenient to provide a scale indicating the residual quantity. Further, it is preferable to provide a handle at an appropriate position because the handle can be easily attached to and detached from the chemical liquid sprayer main body 101.

Therefore, not only do not spill the chemical liquid at the time of preparation for spraying to contaminate the surrounding environment or harm the human body, but also damage the useful plants by mistakenly diluting the amount, and the expected effect is not obtained. The spray preparation can be done easily and surely.

(2) Since the spout 105, which is provided in the liquid medicine container and serves as an outflow passage for the liquid medicine, can be opened and closed by the connector handle 8, leakage of the liquid medicine when the liquid medicine container is removed can be prevented.
It can be reliably prevented by operating the connector handle 8.

(3) Spout 1 as described in the embodiment
If the outer cylinder locking projection 13 on the 05 side and the connection cylinder locking projection 65 on the socket 102 side are provided, the spout 105 is closed when the chemical solution container can be removed, and the chemical solution container is opened when the spout 105 is open. Since it cannot be removed, there is no possibility of accidentally removing the chemical liquid container and causing chemical liquid leakage. When using different types of chemicals, the chemicals container can be removed by washing the chemicals spraying machine main body 101 after removing the chemicals container, and spraying can be performed immediately by setting a new chemicals container. The drug solution remaining inside can also be used by setting the drug solution container at the time of the next spraying. Therefore, it is not necessary to use up the chemical liquid each time it is used, and it is possible to prevent excessive spraying for exhausting the chemical liquid and environmental pollution and waste of the chemical liquid caused by washing away the remaining chemical liquid for chemical liquid exchange.

(4) Since the burden of the chemical spraying work is significantly reduced and work mistakes are prevented, it is a great help to the agricultural workers who are aging.

(5) Recently, a chemical agent has been developed which can obtain a sufficient spraying effect with a small amount of spraying, and even when spraying over a large area, the required amount of the chemical solution can be stored in a small chemical solution container. Especially effective.
