However, in the conventional lubricating oil discharge device described above, since the lubricating oil is recovered by utilizing the increase in internal pressure of the crankcase 1, the airtightness of the crankcase 1 is reduced due to the presence of a clearance provided at the cam tappet, for example. If it is not complete, compressed air will escape from there, making it impossible to improve oil drainage efficiency, and the long oil drain pipe 4 must be connected to the bottom of the oil pan 3 at all times, so the engine There was a risk that the connection portion of the oil drain pipe 4 would crack and break due to the vibration. For this purpose, it has been proposed that an opening is formed in the side of the crankcase and the opening is closed with a side cover. When collecting drained oil, the side cover that closes the opening is removed and the opening is passed through the oil pan. A method has also been adopted in which a drain oil suction pipe is inserted inside the oil pan to suck up the drain oil in the oil pan, but generally the side cover is attached to the outer surface of the crankcase via a packing, and a large number of bolts are attached to the side cover. Because it is attached with
The gasket deteriorated and there was a risk of oil leaking from there. Thus, the present invention focuses on the problems that such conventional lubricating oil discharge devices had, and provides an insertion port into which a drained oil suction pipe can be inserted in the side cover provided on the side surface of the crankcase, and By arranging the blazer plate at the inner end of the insertion port so as not to interfere with pipe insertion, the attachment of a blazer pipe is eliminated, and the replenishment of lubricating oil for the internal combustion engine and the collection of drained oil are simplified. This is not intended.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a front sectional view of a vertical internal combustion engine to which a lubricating oil discharge device according to the present invention is applied, and FIG. 2 is an enlarged sectional view of section A in FIG. 1. In each of these figures, reference numeral 11 denotes a crankcase integrally formed at the bottom of the cylinder block 12;
3 is a crankshaft supported horizontally in a crank chamber 14 surrounded by the crankcase 11;
Reference numeral 15 denotes an oil pan fixed to the lower end of the crankcase 11 by bolts 16, and the oil pan 15 normally contains lubricating oil in an amount such that the liquid level is between the highest level H and the lowest level L. It is stored. Further, the crankcase 11 is provided on its operation side at a height position of the center of the crankshaft 13 for attaching and detaching the large end 17a of the connecting rod 17 to and from the crank pin 18 of the crankshaft 13. It has a horizontally elongated opening 19, which is closed by a side cover 21 bolted through a gasket 20. A part of the side cover 21 is attached to the crankcase 1.
The oil pan 15 has an outwardly bulging shape, and is provided with an insertion port 22 formed in the bulging portion so as to face the bottom 15a of the oil pan 15. Note that the insertion port 22 is used to insert a straight drain oil suction pipe 23 into the crankcase 1 as shown in FIG.
The purpose is to insert the gas into the oil pan 15 from the outside of the crankcase 11, and to discharge the gas separated from the oil mist from the blow-by gas containing a large amount of lubricating oil accumulated in the crankcase 11 to the outside of the machine, the so-called Blazer device gas. An extension pipe 24 is fitted to the outer end of the insertion port 22, and a relatively coarse lubricating oil mesh 25 is inserted into the extension pipe 24.
is removably inserted therein, and a cap member 27 having a groove 26 through which gas can pass is attached to the upper end of the extension tube 24. Furthermore, 28 is a blazer plate whose upper end is fixed with screws 30 to a boss portion 29 formed on the inner surface of the side lid 21, and the blazer plate 28 itself is made of spring steel. , the lower end side covers the crank chamber 14 side opening of the insertion port 22 to prevent oil droplets in the crank chamber 14 from flowing backward through the insertion port 22 to the outside, and to separate the oil droplets from the blow-by gas. It has the function of passing the removed gas, and when an external force is applied, the crank chamber 1
It is designed to bend to the 4th side. In the figure, reference numeral 31 denotes an oil dipstick inserted into a through hole drilled in the side lid 21 in parallel with the insertion opening 22. The lubricating oil discharge device of the present invention has the above-mentioned configuration, and its operation will be explained next. First, as shown in FIGS. 1 and 2, the insertion port 22
When the engine is operated with the lubricating oil mesh 25 inserted and the cap member 27 attached to the upper end of the extension tube 24, the blow-by gas containing a large amount of oil mist in the crank chamber 14 will be removed. As the crankshaft 13 rotates, it collides with the blazer plate 28, oil is separated, oil droplets flow down and are collected in the oil pan 15, and the gas from which the oil mist has been separated is released around the blazer plate 28. It passes through the gap and is discharged out of the machine from the groove 26 of the cap member 27 fitted to the upper end of the extension tube 24. Furthermore, if the amount of lubricating oil in the oil pan 15 is insufficient and you want to add new lubricating oil, all you have to do is remove the cap 27 and pour the lubricating oil through the insertion port 22 into which the lubricating oil mesh 25 is inserted. Said stiff net 2
The lubricating oil from which floating objects and dust have been removed in step 5 can be injected into the oil pan 15 along the inner surface of the crankcase 14. Furthermore, since the lubricating oil in the oil pan 15 has deteriorated due to long-term use, if you want to drain it outside the machine and collect it, use the extension pipe 2 of the insertion port 22.
4 to the cap member 27 and the lubricating oil carp net 25
Remove the drain oil suction pipe 23 from the outside through the insertion port 22 and insert it into the bottom 15a of the oil pan 15.
and drive the oil drain pump (not shown) connected to the pipe 23 via a hose to drain the oil pan 1.
It is sufficient to pump up the waste oil in the tank and collect it in a collection container prepared in advance. At this time, the blazer plate 28 provided on the inner surface of the side cover 21 is bent toward the crank chamber 14 as shown in FIG. After removing 23, it returns to the state shown by the solid line in FIG. 2 and covers the insertion opening 22. FIG. 4 shows another embodiment of the lubricating oil discharge device of the present invention, in which a support plate 32 is fixed to the inner surface of the side cover 21 with screws 30, and a support shaft 33 is fixed to the inner surface of the side cover 21. The upper end of the blazer plate 34 is rotatably hinged through the spring 35, and the blazer plate 34 is interposed between the support plate 32 and the spring 35.
The structure is such that it is always biased in the direction of arrow X. In the drawings, parts with the same reference numerals as in FIGS. 1 to 3 indicate the same members and parts, respectively. In the device having the above configuration, when the drain oil suction pipe 23 is inserted into the insertion port 22 during drain oil recovery,
The blazer plate 34 is pushed by the tip of the drain oil suction pipe 23 and rotated toward the crank chamber, making it easier to insert the drain oil suction pipe 23, and the drain oil collection work is completed and the pipe 23 By simply removing the holder, the holder is rotated in the direction of the arrow X by the biasing force of the spring 35, returns to the position shown by the two-dot chain line, and performs the same blow-by gas mist separation action as in the embodiment described above.

As mentioned above, the lubricating oil discharge device of the present invention is
An insertion port is formed in the side cover of the crankcase having the oil dipstick hole in parallel with the oil dipstick hole, and the insertion hole is oriented toward the bottom of the oil pan attached to the lower part of the crankcase. A Blazer plate that is displaceable toward the inside of the crankcase is disposed at the inner end of the insertion opening on the crank chamber side, and the insertion opening of the waste oil suction pipe is connected to the gas outlet of the Blazer device and the lubricating oil. By making it possible to double as a supply port, when a straight drain oil suction pipe is inserted from the insertion port, the blazer plate is evacuated so as not to interfere with pipe insertion, and after the pipe is removed. The blazer plate is located at the inner end of the insertion port to perform the blazer function, and only the gas from which the oil mist has been separated from the blow-by gas in the crankcase is discharged from the insertion port. Because of this, unlike conventional internal combustion engines, there is no need to connect a blazer pipe inside the crankcase, connect a long drain oil collection pipe to the oil pan, or remove the side cover of the crankcase each time to collect drain oil. , it has the excellent effect of being able to perform waste oil recovery work with high efficiency. Moreover, according to the device of the present invention, the insertion port of the drained oil suction pipe can be used as the gas discharge port and the lubricating oil supply port of the Blazer device, and these can be attached in one place. This makes it possible to effectively utilize the maintenance space around the engine, especially in the case of an engine housed in a narrow engine room such as a ship-mounted engine. This greatly contributes to improving the workability of maintenance.
