Abstract

PURPOSE:To situate a suction hose of an air cleaner to be attached to an opening part in a position more outward than a vertical frame inside surface as well as to facilitate the setting of the suction hose and an engine, by forming the opening part at the inside of the vertical frame installed in a longitudinal direction of the engine flank. CONSTITUTION:A notch part 3 is installed at the inside of a part of hollow vertical frame 2 going along the flank of an engine 1 and the longitudinal direction, thereby constituting an opening part 6 making a suction hose 5 of an air cleaner 4 free of detachment. And, air to be inhaled out of the vertical frame 2 is fed to the inside of the engine 1 by way of the opening part 6, the suction hose 5 and the air cleaner 4. With this constitution, such a possibility that a position of the suction hose 5 is projected largely to the inside from an inner side face of the vertical frame 2 is eliminated, thus the setting of the suction hose 5 and the engine 1 or the like can be made so easily.

Description

[Detailed description of the invention] Industrial applications This invention relates to an air cleaner for a tractor.

Conventional technology In the past, a hollow vertical frame was provided in the longitudinal direction on the side of the engine, a hole was provided on the inner surface of the vertical frame, and an air cleaner suction hose was connected to the hole through the hole.

7) and (17), and this vertical frame (2
), (2) A radiator mounting plate (18) is provided at the front to connect the vertical frames (2), (2), and the vertical frame (2) on the left side when viewed from the front is approximately at the center in the front-rear direction. The inside of the part has a cutout (3) and an opening (6), and the radiator mounting plate (1) has a radiator (19).
The engine (1) having an air cleaner (4) is provided at the rear of the radiator (19).

A suction hose (5) is attached and communicated between the front part of the air cleaner (4) and the opening (6) of the vertical frame (2). The mounting plate (20) has a U-shaped mounting plate (20) on the upper and lower sides and the left and right sides, and this mounting plate (2o) has a suction cylinder (21) whose lower part is in the shape of a mouth and whose upper part is circularly tilted upward. In addition, the upper circular part of this suction tube (21) is provided with a telescopic tube (22) that can be expanded, contracted, and bent.
2) one end is fixed to a cylindrical part (23) protruding from the outer periphery of the front part of the air cleaner (4), and the mounting plate (20)
