Description

[Detailed Description of the Invention] This invention relates to (1) an improvement of an air cleaner for an engine in a power agricultural machine such as a tractor.

In conventional power agricultural machines of this type, a radiator (installed just before the engine) is installed to increase the cooling effect, so the air cleaner for supplying air to the engine is also installed close to this radiator. As a result, maintenance work such as cleaning or replacing the filter element of the air cleaner or the radiator is in a state of trouble.

Therefore, in this invention (1. The upper rear surface of the radiator
The air cleaner, whose front cover is located close to the front cover, is provided so that the area near the front cover can rotate upwards from the radiator by means of a spindle, and the air cleaner, which is located close to the front cover, is provided so that it can rotate upwards relative to the radiator, and the air cleaner, which is located in front of the upper part of the radiator, is connected to the suction pipe and the engine. The front cover can be removed without interfering with the radiator by configuring the air cleaner to communicate with each intake pipe and rotating the air cleaner upward about the support shaft, allowing the air cleaner to be removed without interfering with the radiator.
It has been devised so that the i-ta element can be easily removed.

The specific structure will be explained with reference to an example shown in the drawings, in which a radiator 3 is attached to the machine frame 4 just before the cooling fan 2 that rotates in the engine 1. Above (J bonnet 5I trowel covered, but the 4th
As shown in the figure, a flat plate is bent into a shape to form a receiving plate 6 consisting of leg portions 6a and an upper plate 6b, and a rectangular receiving portion 7 is formed.
A mounting part 7b is extended to the side of the receiving part 7a to form a receiving plate 7 with a shaft support 7c projecting downward in one end of the receiving part 7a. 1 to 3 (as shown in the figure), attach the lower part of the leg part 6a of the receiving plate 6 to the mounting seat 8 protruding from the front side of the engine 1 with the mounting bolt 9. At the same time, the mounting portion 7b of the receiving plate 7 is mounted to the shoulder portion of the engine 1 using mounting bolts 10.

Further, as shown in FIG. 2E, from a receiving part 11a having approximately the same size as the receiving part 7a, the left and right sides are bent upward, and the left and right sides are cylindrical mounting seats 11bt along the bottom of the air cleaner 12.
11b is formed, and the receiving part 11 is
At one end of the bracket 11, a J-shaped shaft support 11c is provided to protrude downward and the mounting seats 11b, 11b are attached to the bottom of the air cleaner 12. 11c, and attach the support shaft 13 to the shaft supports 7c and 11c.
By inserting the front cover 12a of the air cleaner 12 into a position close to the upper rear surface of the radiator 3, when the receiving part 11a is placed on the receiving part 7a, the upper plate part 6b and the receiving part 7a, Female screw seat 11 fixes the threaded portion of butterfly bolt 14 inserted through 11a to the upper surface of receiving portion 11a.
d, the air cleaner 12 will be fixed approximately horizontally on the receiving plates 6 and 7, and the air cleaner 1
The front port 12b of the air cleaner 12 is connected to the intake pipe 15 located in the upper front of the radiator 3, and the rear port 12b of the air cleaner 12 is connected to an intake pipe 16 protruding from the side of the engine 1.
If the air cleaner 1 is connected to the air cleaner 1 through the flexible tube 17,
1. From this state, remove the butterfly bolt 14, disconnect the intake pipe 15 and the front cylinder opening 12b, and connect the air cleaner 12 as shown by the two-dot chain line in FIG. If the front cover 12a is rotated upward about the support shaft 13, the front cover 12a (J) will be located one position above the upper rear surface of the radiator 3.

As described above, the air cleaner according to this invention has a
3, the air cleaner 12 can be rotated upward from the front of the air cleaner 12, so by rotating the air cleaner 12 upward in an extremely simple handling operation, the front cover 12 can be rotated upward without interfering with the alt radiator 3. The filter element in the air cleaner 12 can be removed very easily.

In the past, operations such as removal, inspection, cleaning, and installation of the filter element can be carried out safely in a wide space.
