Description

[Detailed description of the invention] [Industrial application field] This invention relates to a power sprayer with a chemical liquid stirring device used for spraying chemical liquid, and it is possible to increase the degree of freedom in the arrangement of the chemical liquid stirring device. This is about a power sprayer that can be used.

[Conventional technology]

FIG. 3 is a configuration diagram of a conventional power sprayer equipped with a chemical liquid stirring device. The power sprayer 10 has a crankshaft 12
A V-pulley 1 is provided on the output shaft 16 of the engine 14 and the crankshaft 12 of the power sprayer 10, respectively.
8 and 20 are fixed, and the V belt 21 is connected to the V pulley 1.
It is hung between 8 and 20. Chemical liquid tank 22
stores the chemical solution 24 inside and connects the suction hose 26
is fitted with a strainer 28 at one end and inserted into the chemical liquid tank 22, and is connected to the inlet of the power sprayer 10 at the other end. The return hose 30 has one end connected to the chemical solution 24 in the chemical solution tank 22.
The other end is connected to the discharge side of the power sprayer 10 to return excess liquid to the chemical tank 22. The pulsation absorber 32 includes an air chamber, is connected to the outlet of the power sprayer 10, and is connected to the outlet of the power sprayer 10.
Absorbs zero discharge pressure pulsations. The discharge hose 34 is connected at both ends to a respective power sprayer 10 outlet and nozzle (not shown).

During operation of the power sprayer 10, it is necessary to stir the chemical liquid 24 in order to avoid separation of the chemical component and water in the chemical liquid 24. Flexible shaft 33
is connected to the end of the crankshaft 12 at one end, and is submerged in the chemical solution 24 of the chemical solution tank 22 at the other end, and has a stirring blade 35 attached thereto. In this way, as the crankshaft 12 rotates, the rotation of the crankshaft 12 is transmitted to the stirring blade 35 via the flexible shaft 33, and the stirring blade 35 rotates within the chemical liquid 24 in the chemical liquid tank 22, bringing the chemical liquid 24 into a mixed state. It is designed to be held in place.

[Problem that the invention attempts to solve]

The problems of the conventional technique in which the flexible shaft 33 is used to operate the stirring blade 35 are as follows.

(1) The length of the flexible shaft 33 is limited, and usage conditions are restricted.

(2) The flexible shaft 33 does not have sufficient flexibility and is difficult to handle.

(3) The flexible shaft 33 is attached to the crankshaft 12
The chemical liquid 24 in the chemical liquid tank 22
Even if the level of stirring blades 35 decreases, the stirring blades 35 will continue to be driven and there is a risk of damage.

(4) The flexible shaft 33 is expensive.

The purpose of this invention is to provide a power sprayer with a chemical liquid stirring device that can solve the problems of the prior art.

[Means for solving problems]

The power sprayer with a chemical liquid stirring device based on this invention receives power from the generator via a power supply cord and a generator that is linked to the crankshaft of the power sprayer and driven together with the crankshaft. It includes an electric motor and a stirring blade attached to the output shaft of the electric motor.

[Effect]

The generator rotates in conjunction with the rotation of the crankshaft of the power sprayer and generates electric power. The electric motor receives power from the generator via the power supply cord,
Rotate the output shaft. As a result, the stirring blade rotates and mixes the chemical solution, the medicine, and the diluent liquid, which is water.

〔Example〕

This invention will be explained with reference to the embodiments shown in FIGS. 1 and 2. Note that the description of parts that overlap with the description of FIG. 3 will be omitted.

FIG. 1 is an overall configuration diagram. In FIG. 1, the generator 36 is attached to the power sprayer 10, and the drive shaft 50 of the generator 36 (FIG. 2) has a sliding disc 38.
is fixed, and the peripheral edge of the sliding disk 38 and the V pulley 20
are in sliding contact with the periphery of each other. The electric motor 40 is
It is disposed within the chemical liquid tank 22 and has an output shaft 42 . The stirring blade 44 is fixed to the output shaft 42 and is submerged in the chemical liquid 24 in the chemical liquid tank 22 . The power supply cord 46 is connected at both ends to the generator 36 and the electric motor 40, respectively, and is connected to the generator 36 and the electric motor 40, respectively.
The generated electricity of 6 is sent to the electric motor 40. The switch 48 is provided in the middle of the power supply cord 46 and opens and closes the power supply circuit between the generator 36 and the electric motor 40 .

As the engine 14 operates, the output shaft 16 rotates, and the rotation of the output shaft 16 is transmitted to the V pulley 20 via the V pulley 18 and the V belt 21. Since the crankshaft 12 of the power sprayer 10 is integrally connected to the V-pulley 20, the power sprayer 10 is brought into a driving state as the V-pulley 20 rotates. The sliding disc 38 also has a V-pulley 2 at its periphery.
The generator 36 rotates due to frictional sliding with the periphery of the 0, and the generator 36 enters a power generation state. Electric power generated by the generator 36 is supplied to the electric motor 40 via the power supply cord 46, and the electric motor 40 is put into a driving state, and the stirring blades 44
stirs the chemical solution 24 in the chemical solution tank 22. While the engine 14 is running, the switch 48 is turned on and off.
Since the supply of electric power from the generator 36 to the electric motor 40 is controlled, the rotation and stop of the stirring blade 44 is thereby controlled.

FIG. 2 shows another structure for switching between rotating and stopping the stirring blade 44. The sliding disc 38 is the generator 36
The arm 52 is rotatably supported by the casing of the power sprayer 10 at one end, and has the generator 36 fixed at the other end. When the generator 36 is placed in a power generation state, V
The pulley 20 and the sliding disc 38 are brought into sliding contact with each other (solid line position), and the sliding disc 38 is rotated in conjunction with the rotation of the V-pulley 20. Furthermore, when the generator 36 is brought into a state where power generation is stopped,
The V-pulley 20 and the sliding disc 38 are separated from each other (at the two-dot chain line position) so that the sliding disc 38 does not rotate despite the rotation of the V-pulley 20. In FIG. 2, the switch 48 in FIG. 1 is omitted, and instead, the swinging position of the arm 52 can be changed to switch between rotating and stopping the stirring blade 44.

[Effect of idea]

In this way, according to this invention, the generator is driven in conjunction with the rotation of the crankshaft of the power sprayer,
It generates electricity and sends it to the electric motor via the power supply cord, which rotates the stirring blades. The power supply cord has sufficient flexibility and the length can be set arbitrarily, so the position of the stirring blade can be set freely with respect to the power sprayer, making it easy to handle. Moreover, the power supply cord is cheaper and safer than a flexible shaft. In addition, it is easy to install an electric switch in the middle of the power supply cord or to switch between starting and stopping the generator's power generation, so the rotation and stopping of the stirring blades can be easily controlled with a simple structure. becomes possible.
