Description

[Detailed Description of the Invention] The present invention relates to an engine device equipped with a dry cyclone type air cleaner, and more particularly to a dust removal device for an air cleaner.

Conventionally, in the case of machines that generate a lot of dust, such as combine harvesters, air cleaners have generally used a dry cyclone system that uses cyclone action to separate dust and reduce clogging of the filter element. When the dust collection chamber is full,
This has the drawback that sufficient cyclone action is inhibited and the filter element becomes clogged more quickly.
Occasionally, it was necessary to clean the dust collection room. but,
Clogging in the radiator section inevitably requires frequent cleaning, as the radiator cover is frequently opened to check the engine oil and cooling water levels.
In the case of air cleaners, they were not often cleaned, and it was often discovered that the air cleaner element was clogged only after problems such as black smoke coming from the muffler and a drop in engine output occurred.

Therefore, the present invention provides a concave portion in a cover that is frequently opened and closed, such as a radiator cover, so as to face the air cleaner, and when the cover is closed, the area around the concave portion is brought into close contact with the case of the air cleaner to form a dust collection chamber.
It is an object of the present invention to provide an air cleaner dust removing device which is configured to open the dust collecting chamber when the cover is opened to facilitate cleaning of the dust collecting chamber, thereby eliminating the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 2 and 3, the engine 10 is arranged in an engine room R formed by an engine cover 13, and the outer surface of the cover 13 is arranged so as to face the cooling fan 10a. A radiator 15 is disposed at. On the other hand, an air cleaner 17 is attached to the upper outer surface of the engine cover 13 with mounting brackets 50a, 50b and bolts 18, and the air cleaner 17 is connected to a rain cap 52 protruding outward from the aircraft body via an inlet pipe 51. At the same time, it is connected to the intake pipe 10b of the engine 10 via an outlet pipe 53 and an air hose 23 fixed to the pipe 53 with a hose band 55. Also, engine cover 1
A radiator cover 16 is arranged on the outside of 3 to cover the radiator 15.
A hinge 56 is provided at one end in the lateral direction, and a stopper 19 is provided at the other end, so that it can be opened and closed freely. Furthermore, the cover 16 has a wire mesh 2 on the outside of its upper part.
A wire mesh 20b is fixed to the part of the partition plate 21 that communicates with the opening on the side of the cover, and the lower part of the cover 16 becomes a dust collection chamber 22 for dust, etc., removed by the wire mesh 20b. ing. In addition, in the figure, 15a is a radiator mounting plate, 24 is a dust filter, 25 is an engine mounting seat integrated with the fuselage frame 3, 26 is a vibration-proof rubber,
27 is an engine mounting stand.

A recess 1 is provided at a position facing the air cleaner 17 on the outside of the upper part of the radiator cover 16.
Further, an elastic body such as sponge rubber 29 is adhered around the recess 16a, and when the cover 16 is closed, the sponge rubber 29 is attached to the case flange 30a of the air cleaner 17. The recess 16a forms a dust collection chamber 31 of the air cleaner 17.

As shown in FIG. 4, the air cleaner 17 has a cylindrical case 30 with an open end, and a flange 30a is formed around the entire circumference of the open end of the case. , an inlet pipe 51 and an outlet pipe 53 are fixed to the other end closed portion. Furthermore, a filtering element 32 is disposed inside the case 30, and the element 32 has a hollow cylindrical shape, and a rubber packing 33 is fixed to one end of the filter element 32. On the other hand, a cylindrical cap 35 having obliquely formed blades 35a is placed over the cap. Then, the rubber packing 33 is brought into contact with the other end surface of the case 30, and the knock pin 36 is inserted into the hole formed in the flange portion 30a.
Attach the partition plate 37 to the element 32 so that the
The element 32 is attached by abutting one end of the partition plate 37 and fixing the partition plate 37 to a bracket 39 extending from the outlet pipe 53 with a wing nut 40. Moreover, as shown in FIG.
The outer air passage A of the element 32 communicates with the dust collection chamber 31 via the communication portion 37a.

Since the present embodiment has the above-described configuration, when the engine 10 is rotated and the combine 1 is operated, the cooling air generated by the rotation of the cooling fan 10a cools the radiator 15 through the wire meshes 20a, 20b and the dust filter 24. And then engine 1
The air is discharged to the rear through the air intake pipe 10b, and also flows through the rain cap 52 and the inlet pipe 51 to the air cleaner 1 based on the intake air from the intake pipe 10b.
7 is supplied with air. Then, as shown in FIG. 4, the air is subjected to a strong swirling action by the blades 35a, becomes a cyclone flow, and flows through the air path A between the case 30 and the element 32 as shown by the arrow X. Then, due to the centrifugal force based on the cyclone flow, relatively large dust D such as straw is separated and guided to the dust collection chamber 31 through the communication part 37a of the partition plate 37, as shown by the arrow Y, and the dust D is collected. Dust chamber 3
Since the cyclone flow is blocked by the partition plate 37, the dust sent into the air filter 1 accumulates below due to its own weight. On the other hand, from the air from which large dust D has been separated by the cyclone flow, fine dust is removed by the filtration element 32 as shown by arrow Z, and only clean air passes through the outlet pipe 53 and the intake pipe 10b to the engine 10. is supplied to Note that the suction force of the element 32 decreases slightly as it moves away from the outlet pipe 53, that is, as it goes in the direction of arrow C, because the ventilation resistance increases, but the decrease in suction force does not vary greatly over the entire length of the element, and the cyclone flow flows in the direction of arrow C, and there is also a strong cyclone flow effect on the lower part of the partition plate 37. Therefore, even the large dust D' that has accumulated in the lower part of the air passage A when the engine is stopped is sent into the dust collection chamber 31 from the passage 37a by the powerful cyclone flow, and the dust does not accumulate inside the air cleaner. Also,
Since the notch passage 37a of the partition plate 37 is formed in the upper part, the entire capacity of the dust collection chamber 31 can be used effectively. Note that when installing the element 32, the partition plate 37 must be secured to the passage 37 by the dowel pin 36.
It is installed so that a is located above.

Then, to check the engine oil and cooling water level, etc., remove the stopper 19 and remove the radiator cover 1.
6, the dust collection chamber 31 constituted by the recess 16a provided in the cover 16 is opened, as shown by the chain line in FIG. 3, and the dust inside the dust collection chamber 31 is inevitably cleaned. Ru.

In the above embodiment, the dust collection chamber 31 was formed by providing the recess 16a in the radiator cover 16, but the recess may be provided in other covers that are frequently opened and closed, such as the engine cover and the bonnet.

As explained above, according to the present invention, the cover 16, which is frequently opened and closed, such as a radiator cover,
