WATER SUPPLY AND AGRICULTURAL MEDICINES SPRAY APPARATUS FOR AGRICULTURE AND HORTICULTURE}

The present invention relates to agricultural spraying and pesticide spraying apparatus, and more particularly to a device for watering and spraying pesticides for crops grown in agricultural and horticultural vinyl houses or greenhouses.

As is well known, vinyl house cultivation of agricultural products and horticultural crops is common, and since vinyl houses are not watered by natural rainfall, artificial water is supplied by pumping groundwater, and pesticides are used to control pests such as outland cultivation. Spraying.

The above watering method is to install a pump for extracting the groundwater near or inside the plastic house, install a water supply pipe along the longitudinal direction on the ceiling of the vinyl house, etc. and at the same time install a downward watering sprinkler in the water supply pipe The pump discharge pipe is fixedly connected to the water supply pipe so that it can be sprayed on only one plastic house, or the discharge pipe can be selectively connected to the water supply pipe installed in the adjacent plastic house, or a branch pipe can be installed in the discharge pipe to provide at least one water supply pipe. We connect to many plastic houses as one pump while connecting.

In addition, the pesticide spraying method is installed in the vicinity of or inside the plastic house, such as spraying method, the pesticide reservoir and pesticide sprayer, and the pesticide supply pipe parallel to the water supply pipe on the ceiling of the vinyl house and at the same time downward spray sprinkler Alternatively, spray nozzles are installed to spray pesticides on one or more plastic houses in the same manner as the above watering method.

However, the above watering method and pesticide spraying method

First, the installation cost of cultivated crops is high due to the high installation cost due to the separate installation of feed water pump and pesticide sprayer.

Second, since water or pesticide remaining in the water supply pipe or pesticide supply pipe is dropped into the cultivated crop after spraying or spraying the pesticide, the cultivated crop is damaged due to local over-pesticide spraying on the soil below the sprinkler. If it falls locally, the residual amount of pesticides in the soil and cultivated crops will increase, which may cause the growth of the cultivated crops or lose the commercial value of the cultivated crops, which will cause a decrease in productivity.

Third, because the pump must be operated to obtain pesticide dilution water when spraying pesticides, there is a complicated problem.

In view of the above problems, the present invention is to provide a spraying sprinkling and pesticide spraying device for uniformly and conveniently spraying and spraying pesticides, and can produce cultivated crops at low cost by reducing the cost of facilities such as plastic houses. do.

Reference numeral 20 is a filter installed in the suction pipe (2).

The first embodiment of the present invention operates as follows.

① watering

When the valves 9, 10, 18 are opened, the valves 11, 12, 13, 19 are closed and the pump 1 is operated, the groundwater sucked into the suction pipe 2 is pumped (1). Pressurized in the discharge pipe (3) and the water supply pipe (14) is sprinkled by the sprinkler (15) to water the cultivated crop (see arrow 1 dashed line), when the water supply is complete 'off' When the pump (1) is stopped or the pump (1) is an automatic pump (auto pump is provided with a pressure tank and a pressure switch in the discharge pipe of the pump to close the discharge pipe, the pressure switch is 'off' and the pump automatically If the automatic pump is a well-known technique), the operation of the pump 1 is automatically stopped when the valve 18 is closed.

② pesticide spraying

When the valves 10, 11, 19 are opened, the valves 9, 12, 13, 18 are closed, and the pump 1 is operated, the pesticides stored in the pesticide storage tank 6 are pesticides. The pesticide is sprayed onto the cultivated crops by the sprinkler or the spray nozzle 17 while being sucked into the pump 1 via the suction pipe 4 and pressurized to be discharged to the discharge pipe 3 and the pesticide supply pipe 16 (see arrow broken line). When the spraying of the pesticide is completed, the power is 'off' or the pump 1 is automatically stopped when the valve 10 or the valve 19 is closed.

③ Recovery of pesticide remaining in pesticide supply pipe

After spraying the above and pesticides, the valves 12, 13, 19 are opened, and the valves 9, 10, 11 are closed, and the pump 1 is operated to maintain the pesticide supply pipe 16. The pesticide is sucked into the pump 1 via the discharge pipe 3, the pesticide and the dilution water suction pipe 8 (see arrow solid line), and the pesticide storage tank 6 through the pesticide and dilution water discharge tube 5. It is going back.

Recovering the pesticide remaining in the pesticide supply pipe 16 in the pesticide storage tank (6) as described above, because the pesticide does not fall to the cultivated crops through a plurality of injection nozzles 17, to prevent soil contamination, cultivation Increased productivity is achieved because crop residues are low or low.

④ Supply dilution water to pesticide storage tank

If the valve is operated in the same way as the pesticide recovery after watering as shown in ① and above, the water remaining in the water supply pipe 14 is returned to the pesticide storage tank 6 as shown by the solid arrow, and thus the pesticide dilution water can be conveniently obtained. It is.

As described above, the first embodiment of the present invention sprays water and sprays pesticides with one pump 1, recovers the pesticide remaining in the pesticide supply pipe 16 to the pesticide storage tank 6, and remains in the water supply pipe 14. The water supply can be used for dilution of pesticides, thereby reducing facility costs, simplifying spraying and spraying pesticides, and improving the productivity of crops.

FIG. 2 is a perspective view of a second embodiment of the present invention, in which the second embodiment has the same basic configuration and operation as the first embodiment (the same reference numerals are used for the same elements, and detailed descriptions thereof are omitted). The point is that the valve 29 is provided in the middle of the pesticide supply pipe 16, and the bypass conduit 31 is provided between the front of the valve 29 and the front of the valve 19.

When the bypass conduit 31 is installed as described above, the pesticides supplied to the discharge pipe 3 are pesticide supply pipe 16 when the length of the pesticide supply pipe 16 is long (the vinyl house is often about 100 m long). Since the pesticide is supplied by dividing the front and rear of the valve 29 when supplied, the pressure reduction phenomenon at the end of the pesticide supply pipe 16 is prevented, so that the uniform pesticide can be applied to the entire vinyl house.

3 is a perspective view of a third embodiment of the present invention, in which the third embodiment has the same basic configuration and operation as the first embodiment (the same reference numerals are used for the same components, and detailed description thereof is omitted), and the differences Already pre- filed between the plurality of sprinkler (15, 25) and the spray nozzle (17, 27) formed in the water supply pipe 14 and the pesticide supply pipe 16 (detailed configuration and action is my 1999 utility model registration application 14568 and 14569) check valves 33 (described in the previously filed application as valve housings 40) are provided, which are shut off or closed in accordance with a change in the pressure supplied from the pump 1 A plurality of check valves 33 are provided so as to be injected, and check valves 24 and 26 are provided at ends of the water supply pipe 14 and the pesticide supply pipe 16.

When the check valve 33 is installed at the ends of the plurality of sprinkler 25, the spray nozzle 27, the water supply pipe 14 and the pesticide supply pipe 16 as described above, the water supply pipe 14 and pesticide spraying after the spraying or pesticide spraying stop Since the water supply and the pesticide remaining in the tube 16 are recovered and are not dropped on the crop, the productivity of the crop is improved.

The check valves 24 and 26 are closed at the time of water supply or pesticide spraying, and are opened when the pesticide dilution water is supplied to the pesticide recovery or the pesticide storage tank 6 so that air flows into the water supply pipe 14 or the pesticide supply pipe 16.
