Abstract

(57) [Summary] [Purpose] The purpose is to prevent stirring of a chemical liquid tank of an electric sprayer used for horticulture or the like by human means. [Structure] The motor 2 of the electric sprayer is a biaxial motor,
The one shaft 2a is connected to the pump 3, and the other shaft 2b is connected to the stirring device 6 via the bell-bell gear 5. When the motor 2 is operated, the pump 3 also rotates while stirring the chemical liquid in the chemical liquid tank 1 with the stirring device 6, and the chemical liquid is sprayed by the nozzle 4
It is pumped up and sprayed.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric sprayer equipped with a stirring device for chemical liquids.

[0002]

[Prior art]

 As an electric sprayer used for horticulture, etc., a chemical solution in a chemical solution tank is pumped up by a pump and sent to a spray nozzle connected to the pump, and the chemical solution is sprayed from the tip of this spray nozzle to an object. Things are known.

[0003] Usually, the chemical solution is put into the chemical solution tank in a fixed quantity and water is aliquoted and stirred by a human means, and then the pump is operated so that only the spray nozzle at the tip of the chemical solution hose can be used. It is applied to high places and distant places.

[0004]

[Problems to be solved by the device]

 Some chemicals may be harmful if they come into direct contact with your hands or skin, or if you inhale gas.Therefore, you should aspirate the chemicals with a dropper, etc. into a chemical tank, add water, and then stir manually. This was dangerous and was not the preferred method.

If the specific gravity of some chemicals is extremely lighter or heavier than that of water, the chemicals will be separated into two layers in the tank during spraying, and the concentration of the chemicals discharged from the spray nozzle will be too high or too thin. There are many problems such as it is necessary to shake the tank while spraying it because it will be tripped.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an electric sprayer equipped with a pump 3 driven by a motor 2 on a chemical liquid tank 1 and a spray nozzle 4 connected to the pump 3, and the motor 2 The motor of the shaft is an electric sprayer in which one shaft 2a is connected to the pump 3 and the other shaft 2b is connected to the stirring device 6 via the bevel gear 5.

[0007]

[Action]

 In use, water and chemical solution are put into the chemical solution tank 1 in fixed amounts, and the operation case 7 such as the pump 3 is securely mounted on the chemical solution tank 1. After that, when the motor 2 is energized, the pump 3 which is directly connected and the stirring device 6 via the bevel gear 5 start to rotate, and while pumping the chemical liquid in the chemical liquid tank 1 while pumping the chemical liquid, the spray nozzle at the tip is used. The chemical solution is sprayed onto the object from No. 4.

[0008]

【Example】

 Next, the structure will be described with reference to the drawings showing the embodiments. 1 is a bottomed cylindrical liquid medicine tank, 7 is an operation case mounted on the upper portion of the liquid medicine tank 1, 2 is a motor provided in the operation case 7, and 3 is A gear pump is generally used as the pump attached to the single shaft 2a of the motor 2. The pump 3 pumps up the chemical solution in the chemical solution tank 1. In order to prevent the dry operation of the pump 3, it is desirable to provide a mechanism for the chemical solution to flow back into the tank 1 when the discharge pressure becomes higher than a certain level. .

Reference numeral 4 is a spray nozzle, and 4a is a chemical solution hose that connects the pump 3 and the spray nozzle 4, and the spray nozzle 4 is attached to the tip of the chemical solution hose 4a. When the pump 3 is rotated, the chemical liquid is sprayed from the spray nozzle 4 attached to the tip of the chemical liquid hose 4a. Reference numeral 5 denotes a bevel gear attached to the other shaft 2b of the motor 2, which operates a propeller-like stirring device 6 provided in the chemical liquid tank 1 to constantly stir the chemical liquid in the chemical liquid tank 1. Reference numeral 8 denotes a switch provided on the operation case 7, which is used to operate or stop the motor 2 by turning the switch 8 on or off.

Reference numeral 1a denotes an upper edge opening of the externally threaded chemical liquid tank 1, and 7a denotes a fitting projecting edge provided on the bottom of the operation case 7 having internal threading. The fitting projecting edge 7a and the chemical solution tank The chemical solution tank 1 and the operation case 7 are integrally assembled by screwing the upper edge opening portion 1a of the No. 1 screw. As another assembly method, the chemical liquid tank 1 and the operation case 7 may be clamped and integrated.

[0011]

[Effect of device]

 The present invention having the above-mentioned configuration and operation is one in which the pump 3 and the stirring device 6 are simultaneously operated by using one motor 2, so that no human means is required for stirring the chemical liquid, and the harmful chemical liquid is harmful. Does not touch or inhale gas. In addition, since the chemical solution is constantly stirred during the spraying work, the chemical solution does not separate into the upper and lower two layers in the chemical solution tank 1, and it becomes possible to spray the chemical solution at a uniform concentration at all times, which improves safety and spraying performance. It can be kept constant.
