BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest control machine that sprays chemicals, including powder and liquid, stored in a storage case through a jet pipe using air from a suction and exhaust fan.

0002

[Prior Art] Conventionally, this type of pest control machine has been equipped with a fan case for housing a suction and exhaust fan on a backpack frame, an engine for driving the fan, and a fuel supply for supplying fuel to the engine. A storage case containing a tank and medicines including powders and liquids is provided on the fan case, and an air passage is provided for sending compressed air from the fan case into the storage case through a shutter case, and from the storage case through the shutter case. A device is known that is equipped with a supply path for introducing medicine and the like to the outlet of the fan case, and is configured to spray medicine and the like inside the storage case to the outside through a jet pipe.

[Problem to be Solved by the Invention] However, in the conventional pest control machine described above, the storage case, fan case, fuel tank, etc. are formed separately, so each of these elements must be assembled separately for pest control. The machine has to be assembled, which requires a large amount of man-hours, and at the same time, it is necessary to provide a seal structure in each part to prevent liquid leakage, which has the disadvantage that the cost of the pest control machine itself is high. there were.

[0004] Therefore, a technology was developed in which the fan case and the storage case were integrally molded using a synthetic resin material, but since each case was formed in a vertically divided shape, it was difficult to use only for dispersing powder and granules. There have been problems such as the use is limited, it is difficult to seal the mating surfaces of the storage case, it cannot be used for spraying liquids, and it is extremely inconvenient and uneconomical.

[0005]

[Means for Solving the Problems] The present invention addresses the above-mentioned conventional problems, and includes a fan case to which a suction/exhaust fan and an engine are attached, and a storage case provided above the fan case, made of synthetic resin material. The fan case and the storage case are integrally formed by blow molding without any vertical seams, and each of the connecting pipes for supplying the exhaust air from the fan case to the pressurizing device inside the storage case is provided at the connecting part of the fan case and the storage case. It is integrally formed when the case is blow-molded, and both powder and liquid agents can be placed in the storage case and used in common, eliminating the need for liquid leakage prevention seals compared to the past, expanding the range of applications, and making it easier to use the connecting tube. By integrally molding the mounting part at the same time as each case, the connecting pipe can be easily fixed by using a part of each case as the mounting part for the separately provided connecting pipe, and compared to the conventional method, the connecting pipe can be fixed easily. The structure can be easily simplified by further reducing the number of mounting parts, and it also eliminates the problem of chemicals condensing on the upper side of the storage case due to mechanical vibrations and forming a space on the exit side. It is capable of smoothly delivering powder, granules, or liquid medicines at a rate higher than the set value.
