DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical spraying pipe device used for pest control in a tea plantation.

[0002]

2. Description of the Related Art The upper surface 1a of a row of tea trees 1 planted in a ridge is:
Usually, it is formed in an arc shape by mechanical cutting or the like. Conventionally, the chemical solution spraying on the tea tree row 1 is performed as shown in FIG.
A nozzle tube 17 having a length traversing the row of tea trees planted in the ridge in the width direction thereof is curved so as to substantially conform to the arc shape of the upper surface 1a of the tea tree row 1, and the curved nozzle tube 1
, A plurality of spray nozzles 18, 18,... Having the same protruding dimensions are provided at predetermined intervals toward substantially the center of the tea tree row 1 planted in the ridge, and one end of the nozzle pipe 17 is held in a hand. And so on. In the figure, reference numeral 19 denotes a chemical supply hose extended from a pump (not shown).

[0003]

In the case of the conventional curved nozzle tube 17, the chemical liquid is properly applied to the lower part of both sides of the tea tree row 1 planted in the ridges, particularly, the right and left A parts shown in FIG. There was a problem in the control effect because the pests were not supplied and the pests concentrated on the part A.

[0004] Further, the pre-curved nozzle tube 17
In the case of, it is not possible to cope with a case where the arc state of the upper surface 1a of the tea tree row 1 differs depending on the region, the field, etc., and therefore, there is a case where the chemical solution is not uniformly applied, and further, the whole is curved. However, problems such as difficulty in handling for storage and transportation and automation for efficient spraying remain.

The present invention has been made in view of the above circumstances, and aims to improve the control effect by eliminating a portion where a chemical solution is not properly sprayed, and furthermore, to adjust each spray nozzle according to various arc states on the upper surface of the tea tree row. It is an object of the present invention to provide a chemical spraying pipe device for tea gardens, which enables uniform spraying by adjusting the length or exchanging the ejection port portion of each spray nozzle, and further facilitates handling and automation of storage, transportation, etc. I do.

[0006]

According to the first aspect of the present invention, a tea tree row is suspended from a nozzle tube having a length traversing the width of the tea tree row, and a lower end thereof is equidistantly spaced from an upper surface of the tea tree row. A plurality of spray nozzles whose lengths are adjusted as described above are provided at predetermined intervals. According to the first aspect, unlike the related art, the spray nozzle is provided so as to hang down from the nozzle tube. As a result, the chemical liquid is also appropriately supplied to the part A from the upper surface of the tea tree row.

Further, the configuration in which the lower end of each of the spray nozzles is provided so as to be at the same distance from the upper surface of the tea tree row, as described below, is configured by detachably configuring the spray nozzle with respect to the nozzle pipe. When the nozzle tube is a straight tube in consideration of the ease of handling and automation, the drooping dimension of the spray nozzle located at the center in the width direction of the tea tree row is short, and it is successive in both side directions. The arranged spray nozzles are configured to be sequentially longer.

According to a second aspect of the present invention, each of the spray nozzles is configured to be detachable from the nozzle tube. According to the second aspect, by preparing in advance an appropriate number of the spray nozzles having different lengths as adapters, even when the arc states on the upper surface of the tea tree row are different, the respective arc states can be easily changed. , Thus allowing for even distribution.

According to a third aspect of the present invention, the nozzle tube is constituted by a straight tube. According to the third aspect, handling such as storage, transportation, and automation described later are easy. In this case, as described above, the spray nozzle located at the center in the width direction of the tea tree row is short, The spray nozzles that are sequentially arranged in both side directions are configured to be sequentially longer.

According to a fourth aspect of the present invention, the ejection port at the lower end of each of the spray nozzles is configured to be exchangeable. According to the fourth aspect, adjustment of the chemical liquid diffusion angle of each of the spray nozzles and the like can be easily performed by replacing the mouth.
