【考案の詳細な説明】
本考案は、内燃機関を原動機とする動力散布機
の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a power spreader using an internal combustion engine as a prime mover.
農薬散布等に用いる動力散布機は、小型で出力
が高いことが望まれており、そのため従来の動力
散布機では気化器吸気胴の内径を拡大することで
出力の向上をはかつてきたが、この方法だと低速
時に燃料吸い出しに十分な吸気負圧が得られない
ため、スロツトル全開状態での再始動性及びアイ
ドリングからの加速性が悪くなるという問題があ
つた。 Power spreaders used for spraying pesticides, etc. are desired to be small and have high output.For this reason, conventional power spreaders have been able to improve their output by enlarging the inner diameter of the vaporizer intake barrel. With this method, it is not possible to obtain sufficient intake negative pressure to suck out fuel at low speeds, resulting in poor restartability with the throttle fully open and poor acceleration from idling.

著しく限定されてしまうという問題があつた。 In addition, as in the power exterminator described in Japanese Utility Model Application No. 52-156809, a part of the air pressurized by the blower is guided to the air cleaner intake port of the engine through a connecting pipe, etc., to reduce the engine output. Some engines have been designed to increase the engine speed, but the problem has been that the engine output cannot be finely adjusted depending on the work content, so the applications are extremely limited.

れるものとする。 In view of the above-mentioned problems, the present invention connects the inside of the fan case and the inlet of the carburetor intake barrel with a duct, and also provides an air amount adjusting plate in the middle of the duct that opens and closes in conjunction with the throttle valve of the internal combustion engine. By forcibly feeding pressurized air into the intake cylinder of the machine, it is possible to improve the output while improving acceleration and restartability without deteriorating them, and finely adjust the output according to the work content. This will be explained based on an embodiment shown in FIG. 1. 1 is an internal combustion engine which is a prime mover, and 2 is a vaporizer of the internal combustion engine 1. A fan case 3 is fixed to the internal combustion engine 1 and has an air outlet 3a.
5 is a fan fixed to the output shaft of the internal combustion engine 1 so as to be able to rotate within the fan case 3; 5 is a duct for communicating the inside of the fan case 3 (high pressure generation part) with the intake barrel inlet of the carburetor 2; , 6 are containers provided at the top of the fan case 3 to temporarily store pesticides and the like and supply them into the fan case 3. Reference numeral 7 indicates a butterfly-type air volume adjustment plate pivotally mounted in the middle of the duct 5, and reference numeral 8 indicates a piston-type throttle valve (not shown) inside the carburetor 2 at one end, and a throttle operation knob (not shown) at the other end. 9 is a terminal provided in the middle of the wire 8, 10 has one end connected to the operating lever (not shown) of the air volume adjustment plate 7, and the other end connected to the terminal 9.
The air amount adjusting plate 7 is made to open and close in conjunction with the throttle valve when the throttle is operated, and by adjusting the linkage at the terminal 9, the air amount adjusting plate 7 can be adjusted to the throttle opening degree by adjusting the linkage at the terminal 9. The timing of opening and closing can be adjusted freely. Note that even when the air amount adjusting plate 7 is in the fully closed position, the minimum opening required for starting and idling the internal combustion engine 1 is maintained.

微少調整を行うことができる。 The power spreader according to this embodiment is configured as described above, and the air pressurized within the fan case 3 is forcibly fed into the intake barrel of the carburetor 2 through the duct 5. The charging efficiency of the internal combustion engine 1 is increased and the output of the internal combustion engine 1 is significantly improved. In this case, since the inner diameter of the carburetor intake shell has not been expanded in any way, sufficient negative pressure can be obtained for fuel suction even at low speeds, resulting in improved restartability with the throttle fully open and acceleration from idling. There is no sexual deterioration. On the contrary, since the main jet becomes larger due to supercharging, the above-mentioned restartability and acceleration performance are further improved. Further, according to this embodiment, since the start timing of the supercharging action can be freely adjusted by the air amount adjusting plate 7, an output range and a fuel efficiency improvement range can be provided. Furthermore, if the chemical to be sprayed is in the form of powder, it needs to be sprayed over a long distance, so a large output is required, but if it is in the form of a liquid dissolved in water, it can be sprayed nearby, so such a large output is not required. If you try to adjust the magnitude of this output only by opening and closing the throttle valve, the output will fluctuate greatly because the pressurized air inside the fan case 3 is being sent into the intake cylinder. It is difficult to make fine adjustments. Therefore, by adopting the air amount adjustment plate 7, when a large output is not required, it is possible to control the flow of pressurized air into the intake cylinder to reduce fluctuations in the rotational speed of the internal combustion engine. You can make small adjustments to the output.

している。 As mentioned above, the power spreader according to the present invention can realize an increase in output while improving acceleration and restartability without deteriorating them, and can finely adjust the output depending on the work content. It has the extremely important practical advantage of expanding its uses.
