Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crankcase device for a power sprayer.

Conventionally, in power sprayers, the water absorption part seal and the seal that prevents oil leakage from the crankcase are close to each other, so water easily enters the crankcase, causing the oil level to rise.
It was not possible to visually recognize the same state directly, which was really inconvenient.

In this invention, in order to make it possible to see through the oil level inside the crankcase from the outside, a visual recognition window made of transparent plastic or the like is installed in the crankcase, and the amount of water intruding into the crankcase can be checked before starting the power. It is an object of the present invention to provide a crankcase device for a power sprayer that allows easy checking and has an oil level overflow pipe and breather protrudingly provided in case of an oil level abnormality.

The embodiment of the present invention will be explained in detail based on the drawings.
A shows a stationary power sprayer, in which a prime mover section 2 is mounted on the right side of the machine body 1, a power sprayer 3 is mounted on the left front side of the prime mover section 2, and the prime mover section 2
A power transmission pulley 4 is protruded from the left side, and
A power receiving pulley 5 is protruded from the right side of the power sprayer 3, and an endless belt 6 is installed between the pulley 4 and the pulley 5.
By suspending the motive power unit 2, power is transmitted from the prime mover unit 2 to the power sprayer 3.

The power sprayer 3 mainly consists of a crankcase 7, a cylinder section 8, and a hose take-up reel 9. Inside the crankcase 7, there is a power receiving pulley 5.
A crankshaft 10 is provided in the center, and a rear end of a connecting rod 11 is rotatably pivoted on the same axis, and a piston 13 is connected to the front end of the connecting rod 11 via a piston pin.
The piston 13 is mounted in the crankcase 7.
The chemical solution B is caused to reciprocate back and forth within the cylinder section 8 protruding from the front side, sucks the chemical solution B through the chemical suction pipe 14, and causes it to flow into the chamber 15 provided upright on the upper surface of the cylinder section 8. ,
Furthermore, it is configured to spray from the tip of a spray pipe 18 via a hose 17, and to circulate the remaining liquid via a remaining liquid discharge pipe 19.

Hose take-up reel 9 for winding the hose 17
are connected to the crankshaft 10 via gears, and are configured to automatically wind up the hose 17 after the spraying operation is completed.

Visual recognition window 2 on the front of the right side wall of the crankcase 7
0, and in order to make the lower half of the inside of the case 7 transparent, the window 20 is made of a member such as transparent plastic into a vertically long rectangle, and the machine frame 21 is provided around the periphery. A scale 22 is provided in the vertical direction on the right side of the surface of the window 20, and the oil is filled to a predetermined position in the case 7. An oil level overflow pipe/breather 23 is provided at a predetermined limit position of the oil level, and the pipe 23 is located close to the visual recognition window 20. It stands up from the oil level, and is bent outward at a right angle at a predetermined oil level limit position so as to protrude outward from the same window 20, and the front half is bent downward. The pipe 23 is configured to control an abnormal rise in the oil level, to discharge air bubbles generated in the oil to the outside, and to keep the air pressure inside the case 7 constant.

The embodiment of the present invention is constructed as described above, and when performing pest control work, before driving the power sprayer 3, a visual recognition window installed to allow the inside of the crankcase 7 to be seen through is installed. 20, the position of the oil level in the case 7 and the amount of water that has entered the oil in a separated state below are checked in advance. If not, by filling oil from the oil filler port (not shown) provided in the same case 7, the scale 22 provided in the same window 20 can be used to position the oil level at a predetermined position, and the amount of infiltrated water, etc. The oil can be removed by a drain (not shown) provided on the bottom of the case 7, and if the oil level rises abnormally, the oil can overflow to the outside of the case 7 via the oil level overflow pipe/breather 23. Please check the same, and
After the repair, power is generated from the prime mover section 2, and the same power is transmitted to the power sprayer 3 via the endless belt 6.
At the same time, by driving the crankshaft 10 built into the crank case 7 of the sprayer 3 and interlocking the piston 13 back and forth through the connecting rod 11, the chemical solution B is transferred through the chemical solution suction pipe 14. At the same time as suction, the liquid supply pipe 16
Work is carried out by flowing out into the interior and then spraying from the tip of the spray pipe 18 via the hose 17. The pipe 23 has the function of discharging air bubbles generated in the oil inside the case 7 to the outside, and also functions to keep the air pressure inside the case 7 constant.

According to the present invention, a visual recognition window is installed on the side wall of the crankcase so that the inside of the case can be seen through, and an oil level overflow pipe and breather is provided protrudingly. This has the effect of not only being able to easily check the condition, but also controlling abnormal rises in the oil level and discharging air bubbles generated in the oil.
