Abstract

A blockage occurs due to foreign matter in the liquid tank of a blower-type drug dispenser when used for a long period of time. The blower-type drug dispenser (1) includes a drug supply pipe (7) that is removably connected to the liquid tank (6). A strainer (32) for the liquid tank (6) is configured so as to be removable from the liquid tank (6) by removing the supply pipe (7) from the liquid tank (6). The drug in the liquid tank (6) is mixed with the airflow in a blower pipe (7) and subsequently dispensed.

Description

送風式薬剤散布機Blower type chemical spreader
　本発明は、液体状や粉体状のたとえば薬品、農薬のような薬剤を送風管の空気流と混合して散布する送風式薬剤散布機に関する。 The present invention relates to a blowing type medicine spreader that mixes and spreads liquid or powdery drugs such as medicines and agricultural chemicals with an air flow in a blowing pipe.
　液タンクに薬液を入れ、液タンクから供給する薬液を送風機の空気流と混合して散布する送風式薬液散布機が知られている（たとえば特許文献１）。 There is known an air blowing type chemical liquid spraying machine that puts chemical liquid into a liquid tank and mixes the chemical liquid supplied from the liquid tank with the air flow of the blower and sprays the liquid (for example, Patent Document 1).
米国特許２００９／０００８４７３号公報（ＵＳ２００９／０００８４７３　Ａ１）US2009 / 0008473 (US2009 / 0008473 A1)
　しかしながら、特許文献１に示す送風式薬液散布機は、液タンクの下部にホースが接続されている。
　液タンク内の薬液は、使用時に、ホースを通じて、空気流に噴霧するノズルへ供給される。
　その結果、薬液に異物が混入していると、薬液とともに異物が送られて、ノズルでの目詰まり、または液タンクからノズルまでの薬液の供給路に設けたバルブまたはコックでの目詰まり、が発生することがある。 However, the blower type chemical liquid spreader shown in Patent Document 1 has a hose connected to the lower part of the liquid tank.
The chemical liquid in the liquid tank is supplied through a hose to a nozzle that sprays into the air flow when in use.
As a result, if foreign substances are mixed in the chemical liquid, the foreign substances are sent together with the chemical liquid, and the nozzle is clogged or clogged by the valve or cock provided in the chemical liquid supply path from the liquid tank to the nozzle. May occur.
　長時間使用することで、送風式薬剤散布機では、液タンク内の異物によって目詰まりが発生する。 When used for a long time, clogging occurs due to foreign matter in the liquid tank in the blower type chemical spreader.
　本発明の送風式薬剤散布機は、タンクの薬剤を送風管の空気流と混合して散布する送風式薬剤散布機であって、タンクは、ストレーナを有し、タンクに対して薬剤の供給管を取外し可能に接続し、供給管をタンクから取外すことによってタンクのストレーナがタンクから取り外し可能に構成される。 The blower-type medicine spreader of the present invention is a blower-type medicine spreader that mixes and sprays the medicine in the tank with the air flow in the blower pipe, the tank having a strainer, and the medicine supply pipe to the tank The tank strainer is configured to be detachable from the tank by removably connecting and removing the supply pipe from the tank.
　好適には、ストレーナは、タンクから取外し可能な供給管に接続されてよい。 Preferably, the strainer may be connected to a supply pipe that is removable from the tank.
　好適には、供給管に接続されるストレーナは、供給管の先端から突出し、供給管をタンクに装着することによりタンクの内部に突出してよい。 Preferably, the strainer connected to the supply pipe may protrude from the tip of the supply pipe, and may protrude into the tank by attaching the supply pipe to the tank.
　本発明では、タンクに対してストレーナを設けている。よって、本発明では、タンク内の異物や沈殿した薬剤が、使用時に、薬剤の供給管へ供給され難い。供給管において、目詰まりが発生し難くなる。
　しかも、このストレーナは、タンクから供給管を取外すことによってタンクから取り外し可能に設けられる。よって、目詰まりしたストレーナの清掃または交換が容易である。
　その結果、長時間使用しても、送風式薬剤散布機において、タンク内の異物によって目詰まりが発生し難くなる。 In the present invention, a strainer is provided for the tank. Therefore, in the present invention, it is difficult for the foreign substances in the tank and the precipitated drug to be supplied to the drug supply pipe at the time of use. In the supply pipe, clogging is less likely to occur.
Moreover, the strainer is detachably provided from the tank by removing the supply pipe from the tank. Therefore, it is easy to clean or replace the clogged strainer.
As a result, even if it is used for a long time, clogging is less likely to occur due to foreign matter in the tank in the blown medicine spreader.
