By driving the drive gear by the main purpose is to save energy due to power consumption.

In general, in spraying pesticides on fruit trees in orchards, the spray nozzle installation fixtures of arbitrary height are spoken from the pesticide supply pipe to the bottom of the orchards, and the pesticides are sprayed on the fruit trees.

In this case, the spray nozzles are always fixed at a certain height so that the pesticides cannot be evenly spread on the fruit trees.

That is, the spraying direction of the spray nozzle is generally installed in the upper middle of the fruit tree, so that the pesticide is sprayed on the middle or upper middle of the fruit tree, but the upper part of the fruit tree is not easily included in the spraying range of the pesticide. Since the pesticide is administered to the fruit tree leaves due to the natural fall of the sprayed pesticides, the pesticides are not evenly spread over the whole fruit tree, and in particular, the leaves distributed above or below the fruit tree. Insects attached to the bottom of the fruit cannot be dropped by spraying pesticides, so the effect of preventing pests is greatly reduced, and fruit harvesting is also significantly reduced.

The present invention has been created to solve the above problems, it is to dispense while moving the spray nozzle up and down to spray the pesticide evenly on the fruit trees.

When described in detail by the accompanying drawings as follows.

The valve 15 or the valve 16 side of the drive is opened to supply the pesticide to the inlet 17 or the inlet 18 of the drive impeller C to rotate the drive impeller C counterclockwise or clockwise. In addition, the rotating hole 19 of the driving impeller C also rotates, and at the same time, the pesticide through the driving impeller C passes through the supporting rods 6 and 7 through the outlet 20 to the injection nozzle 8. (9) sprays pesticides, and valves (15) and (16) also when the switching device (B) is mechanically switched. If so as to open and close to be able to make the operation as described above.

That is, when the up and down movement automatic switching button (10) (11) touches the up and down movement height adjustment stop (12) (13), the operation (not shown) connected to the button opens and closes the valves (15) and (16). can do.

In addition, the pesticide container and the collecting container 14 is connected to a flat pesticide spray solution supply pipe 21 connected to the pesticide supply pipe installed at the bottom of the orchard, and the supplied pesticide is introduced into the valve 15 or the valve 16 side. It is possible to apply a two-way valve or a three-way valve configured so that, as described above, when the switching device (B) is a solenoid valve, the switching device (B) is a switching device (B) in the case of a solenoid valve. The pesticide is supplied to the valve 15 or the valve 16 side by the movement of the installed plunger B-1, that is, the drive box 3 is raised so that the upper movement automatic switching button 10 of the guide support 2 is moved. When it comes in contact with the limit switch 12A of the upper moving height stop 12, the switching device B is driven so that the plunger B-1 opens the valve 15 side and closes the valve 16 side to close the valve 15. Driven impeller (C) is rotated by the pressure of the pesticide The drive box 3 is configured to be lowered by being transferred.

Of course, when the drive box 3 rises, the valve 15 side is closed and the valve 16 side is opened in the opposite manner to the above.

As described above, when the driving impeller C is rotated, the rotating hole 19 of the driving impeller C is also rotated, and the rotating hole 19 has a shaft 22A of the small gear 22 of the driving gear part D. Is connected, the small gear 22 is to make the large gear 23 is meshed, another large gear 24 is meshed with the large gear 23, each of the large gear 23, 24 Another large gear 25, 26 is engaged with the center gear 23A, 24A, and another large gear 27 is engaged with the center gear 25A, 26A of each of the large gear 25, 26. (28) The pinions (4) and (4A) provided at the center of each are configured to move up and down in engagement with the rack (2A), and can be changed by adjusting the ratio of each gear.

In the present invention, the support rods 6 and 7 can be configured to expand and contract, and the vertical movement height adjustment stops 12 and 13 can be arbitrarily adjusted to set up and down operating distances. The support 2 can be disassembled and coupled at regular intervals and the user can arbitrarily change the appropriate height.
