[Prior art]

 For example, in a power sprayer that performs control work in an orchard, it is common to pressurize the chemical solution stored in the tank with a high-pressure plunger pump and spray it with a nozzle. At that time, the spraying operation is performed while constantly stirring the chemical solution in the tank so that the chemical solution can be sprayed at a constant dilution concentration without stagnation. In a vehicle-type extermination work machine equipped with a tank such as a speed sprayer, a stirring blade is rotated in the tank by a driving force from a driving source.

However, when it is not a vehicle-type exterminating machine, a tank is placed on the bed or the ground of a small truck, an electric motor that is a drive source is fixed to the tank, and the output shaft of the electric motor is fixed. While the chemical solution in the tank is being agitated by the rotary blades (fins) attached to, the chemical solution in the tank is sucked up by the pump and sprayed. 7 and 8 show a tank equipped with such a conventional chemical liquid agitator.

FIG. 7 is a vertical cross-sectional view showing an outline of a conventional chemical liquid tank with a chemical liquid stirrer driven by an electric motor, and FIG. 8 is an enlarged view of a main part showing details of a mounting portion of the chemical liquid stirrer of FIG. In FIGS. 7 and 8, the output shaft 51 of the electric motor 50 is connected to the rotary shaft 12 a inserted in the stirring transmission pipe 12. A fin 13 is fixed to the tip of the rotary shaft 12a so that it can be rotated by the driving force of the electric motor 50 to stir the chemical solution in the tank 60. The fins 13 are surrounded by a fin cover 14 attached to the lower end of the stirring transmission pipe 12 via a fitting 15a to prevent damage accidents. The fin cover 14 has a columnar shape as a whole, and is composed of a plurality of upper frame members 15 and a flat plate-shaped bottom cover 16 which are stretched radially.

In this way, the chemical liquid stirrer 1 composed of the fins 13, the fin cover 14, and the stirring transmission pipe 12 is submerged in the chemical liquid 61 in the tank 60, and the bottom cover of the fin cover 14 is described. 16 is placed on the bottom surface of the tank 60, and the upper portion of the stirring transmission tube 12 is attached to the base portion 62 of the tank 60 via a fixing metal fitting 70. As shown in detail in FIG. 8, the fixing metal fitting 70 is composed of a clamp formed so as to straddle a rising portion 63 from the mouthpiece portion 62, and a fixing handle composed of bolts and nuts from the outer side and the inner side thereof. By tightening both 71 and the height adjusting handle 72, the stirring transmission pipe 12 is tightened to the mouthpiece portion 62, and the chemical liquid agitator 1 is fixed to the tank 60.

[0006]

[Problems to be solved by the device]

 However, in the conventional chemical liquid tank with a chemical liquid stirrer as described above, since the chemical liquid stirrer is attached to the tank in a cantilevered manner, the tank is especially suitable when the fin cover is suspended in the liquid. However, if it is attached to the base, there is a problem that not only the mounting strength but also the mounting stability is lacking. Therefore, the bottom cover of the fin cover must be supported by the bottom surface of the tank, but even in that case, when the chemical stirring machine is started, the fin cover receives a rotational force due to the influence of the starting torque, and the stability of the support is impaired. Further, the bottom surface of the tank is not always flat, and for example, when a recess for the drain is formed, there is a problem that the installation location of the bottom cover is restricted. Furthermore, if the height adjustment handle is unfastened to adjust the height (depth) of the fin cover, the chemical agitator itself may come off the tank.

The present invention has been made in view of the problems of the conventional chemical liquid tank with a chemical liquid stirrer, and its object is to particularly, the depth and the size and shape of the diameter of the mouth of the tank. , Or the undulation of the bottom surface, the chemical stirrer can be easily attached to and detached from the tank, and its mounting strength and support stability are secured, and the chemical stirrer is firmly attached to the tank. It is an object of the present invention to provide a chemical solution tank with a chemical solution stirrer in which the length of the stirring transmission shaft can be easily changed while maintaining the state.

[0008]

It is fixed on the support plate 30 by projecting it downwardly, and the support plate 30 is laterally laid across the left and right on a rising portion 81 projecting around the mouth of the tank 80 by a fixture 40. It is fixed by tightening the fixture 40 (details will be described later). The support plate 30 and the attachment 40 constitute a chemical liquid agitator attachment device.

Next, details of the chemical liquid agitator mounting device will be described. 4 is a plan view of a support plate 30 for supporting the engine 20 equipped with a chemical liquid stirrer, FIG. 5 is an enlarged side view of a main part of a fixture 40 for mounting the support plate 30 on the tank 80, and FIG. 6 is VI-VI of FIG. FIG. As shown in FIG. 4, the support plate 30 is a member for mounting and fixing the engine 20, and is made of, for example, a rectangular plate material made of stainless steel, and the deceleration output shaft 21 of the engine 20 is rotatably provided at the center thereof. A round hole 31 for inserting is formed, and a mounting hole 32 for inserting the mounting tools 40, 40 on both sides in the longitudinal direction across the round hole 31 and a mounting long hole for adjusting the mounting position in the horizontal direction. 33 is drilled.

5 and 6, the fixture 40 includes a fixing member 41 having a groove 43 having a U-shaped cross section for holding the support plate 30 from above and below, and a rising portion 81 of the tank 80 from below. It has a pressing member 42 for pressing. A fastening member 44 is provided for connecting the fixing member 41 and the pressing member 42 and adjusting the gap between the two members 41, 42.

The tightening member 44 is composed of a shaft portion 45 having a male screw threaded on the lower portion, and a handle portion 46 for controlling the tightening of the shaft portion 45 to the pressing member 42. The shaft portion 45 is penetrated by a through hole 47 formed in the fixing member 41 and is loosely penetrated by the attachment long hole 33 (or the attachment hole 32) of the support plate 30, and further by the pressing member 42. It is screwed into the formed female screw hole 48. A round bar guide member 49 is vertically provided on the lower surface of the fixing member 41 by a fixing means such as welding, and the lower end portion of the guide member 49 is formed in the pressing member 42. It is loosely inserted into the through hole 42a to allow linear movement in the vertical axis direction. As can be seen from FIG. 1, the fixture 40 is so constructed that it can be attached to the support plate 30 from opposite directions with respect to the width direction of the support plate 30, and the fixture having the same shape member is used. Therefore, increase in manufacturing cost can be suppressed.

In this way, since the mounting position of only the one-sided mounting tool can be greatly adjusted, the engine with the chemical liquid agitator can be easily mounted to the tank. As described above, in the state where the engine 20 is fixed to the tank 80, the rotation torque of the engine 20 passes through the output shaft 21, the stirring transmission shaft 12, and the rotation shaft 17, The chemical solution is transferred to the fins 13 of the agitator 10 supported on the bottom of the tank 80. Then, due to the rotational force of the fins 13, the chemical liquid in the tank 80 circulates as shown by the arrow in FIG. 2 and is sufficiently stirred. Further, the rotation speed of the fin 13 can be freely changed according to the working condition by adjusting the throttle opening of the engine 20.

Further, according to the chemical liquid tank with the chemical liquid stirrer according to one embodiment of the present invention, the fins may be formed according to the internal shape of the tank 80, the physical properties of the chemical liquid such as the residual amount of the chemical liquid and the viscosity of the chemical liquid, or the working condition. When it becomes necessary to change the position of the fins 13, the length adjusting member 18 moves the rotary shaft 17 up and down to adjust the height of the fins 13 from the bottom surface of the tank 80 and from the side surface. The distance can be adjusted.
