Description

[Detailed Description of the Invention] The present invention relates to a dustproof device for a radiator, and is designed to prevent the cooling fan and the dustproof net from being damaged due to the dustproof net being sucked into the cooling fan of the radiator.

For example, in agricultural tractors, as a method of cooling the radiator, a suction-type cooling fan that blows hot air against the operator has been abolished, and instead a discharge-type cooling fan that blows cooling air from behind the radiator toward the radiator is used. However, in this type of conventional device, a cooling fan is provided in a wind cylinder that projects rearward from the radiator, and a dustproof net is provided behind the cooling fan so as to close the rear end opening of the wind cylinder. Therefore, the dustproof net is attracted by the cooling fan, and the dustproof net comes into contact with or gets caught in the cooling fan, which may cause damage to the cooling fan and the dustproof net.

This invention solves the above problems, and its features include a wind barrel protruding from the radiator,
In a vehicle in which a cooling fan that blows air toward a radiator is provided in the wind barrel, the wind barrel is provided so as to be openable and closable on one side relative to the radiator, and the radiator in the wind barrel and the cooling fan are connected. Between,
The dustproof net is provided so that it can be inserted and removed from between the radiator and the wind barrel when the wind barrel is opened.

Hereinafter, the present invention will be explained according to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a tractor body, which is composed of an engine 2, a transmission case, and the like. Reference numeral 4 denotes a pair of left and right frames projecting forward from the engine 2, and a radiator 5 and a battery 6 are mounted on the frames 4. 7 is a front wheel, and 9 is a bonnet that covers the engine 2, radiator 5, etc. Reference numeral 10 denotes a water pump pulley for the engine 2. Power is transmitted from the crankshaft via a belt 11. A cooling fan 12 is provided on the shaft to which this pulley 10 is attached.
2. The radiator 5 and battery 6 are arranged in series in front of the engine 2. This cooling fan 12
is a cold air forward discharge type, and the air sucked into the bonnet 9 from the left and right sides of the bonnet 9 is passed through the radiator 5 from the rear to the front to cool the radiator 5. Battery 6 is storage box 13
It is protected from hot air from the radiator 5. The radiator 5 has an upper tank 14 and a lower tank 15 as shown in FIG.
A water pipe 16 is provided between these tanks 14 and 15, and a wind barrel 17 is provided on the radiator 5 to project rearward. As shown in FIGS. 2 and 3, the wind barrel 17 has a cylindrical shape with a narrowed front side, a rectangular tube shape on the front side, and a cylindrical shape on the rear side.
The right side of the wind barrel 17 is connected to the radiator 5 from its front end.
It is fixed to the right side of the radiator 5 by screws 19 or by welding or the like through a mounting piece 18 that protrudes forward along the right side of the radiator 5, and the left side of the wind cylinder 17 extends from its front end along the left side of the radiator 5. It is removably fixed to the left side of the radiator 5 with a butterfly bolt 21 via a mounting piece 20 protruding forward, as shown in FIG.
When the wing bolt 21 is removed, the left end of the wind barrel 17 can be opened rearward by elastic deformation of the mounting piece 18 or the right end of the wind barrel 17. The cooling fan 12 is arranged at the rear inside the wind barrel 17, and a dustproof net 22 is provided at the front end so as to close the space between the fan 12 and the radiator 5. The dustproof net 22 has a rectangular shape having a net portion 23 and a frame portion 24 surrounding the outer periphery.
The upper and lower ends of the frame portion 24 are fitted to a pair of upper and lower rails 25 fixed to the rear surface of the radiator 5 so as to be able to slide in the left and right directions, respectively, and the dustproof net 22 is connected to the radiator 5 when the wind barrel 17 is opened. It can be freely inserted and removed from between the wind barrel 17 and the left side. In addition, the dustproof net 22
is fitted to the rail 25 with a certain degree of tightness to prevent it from sliding unexpectedly due to vibrations of the vehicle body 1, etc.

According to the configuration of the above embodiment, the cooling fan 12 sucks cooling air into the bonnet 9 from the left and right sides of the bonnet 9 by rotation, and blows the cooling air toward the radiator 5 within the wind barrel 17. Dirt and dust in the cooling air are removed by the dustproof net 22 before reaching the radiator 5. At this time, the cooling air pushes the dustproof net 22 forward, that is, the fan 12
Therefore, the cooling fan 1
There is no risk that the dustproof net 22 will get caught up in or come into contact with the dustproof net 22. Furthermore, since the dustproof net 22 is provided at the front end of the wind barrel 17, the dustproof net 22 can be made larger compared to the case where it is provided at the rear side, and clogging of the dustproof net 22 can be prevented accordingly. Furthermore, when the left end of the wind cylinder 17 is pulled rearward after removing the butterfly bolt 21, the wind cylinder 17 is opened to the rear as shown by the chain line with the right end side as a fulcrum, and the wind cylinder 17 and the radiator 5 are separated. Since the left end side has a large opening, by inserting your hand through this opening and pulling the dustproof net 22 to the left side, you can easily take out the dustproof net 22 from there. Therefore, the dustproof net 22 can be cleaned and Replacement can be done easily.

FIGS. 4 and 5 show another embodiment, in which a gutter-shaped dust receptacle 26 is provided at the lower end of the frame 24 of the dustproof net 22 and extends over the entire length in the left and right direction, and the left end of the frame 24 A handle 27 is provided protruding from the top. The other points are the same as those of the previous embodiment, and the same effects are achieved.

FIG. 6 and FIG. 7 show further other embodiments,
The right end of the wind barrel 17 is pivotally supported on the right side of the radiator 5 by a hinge 28 so that the left end can be opened and closed on one side. Further, a locking shaft 29 is provided on the left side of the wind barrel 17 so as to protrude outward to the left, and an engaging piece 30 that removably engages with the locking shaft 29 is provided on the left side surface of the radiator 5 around the horizontal shaft 31. It is rotatably provided, and the wind cylinder 17 can be locked in a closed state with respect to the radiator 5 by engaging the engaging piece 30 with the locking shaft 29. Other points are the same as in the previous embodiment.

According to the present invention, since the dustproof net is provided between the radiator and the cooling fan in the wind barrel, there is no risk that the dustproof net will be sucked into the cooling fan and come into contact with or be caught in the fan. It can prevent damage to cooling fans and dustproof screens. In addition, the wind barrel can be opened and closed in a single-sided manner relative to the radiator, and the dustproof screen can be inserted and removed from between the radiator and the wind barrel when the windbody is opened, so the dustproof screen can be cleaned and replaced. can be done easily, and its practical effects are significant.
