Description

[Detailed Description of the Invention] The present invention relates to an improvement of a radiator cover that is installed on the body of a harvester or the like so as to surround the front of the radiator of the engine of the harvester or the like.

To explain in detail according to the drawings of the embodiment, in FIG. 1, 10 is a body of a combine harvester A, which is a harvesting machine, 11 is a reaping section mounted on the front end of the body 10, 11 is a threshing section,
13 is a traveling device, and E shown in chain lines is an engine mounted on the fuselage 10 to drive the reaping section 11, etc.;
Reference numeral 20 denotes a radiator cover that is attached to the aircraft body 10 so as to surround the front surface of the radiator R of the engine E.

As shown in FIG. 4, the radiator cover 20 forms a radiator chamber that accommodates the radiator R at the front end side of a box-shaped machine frame 30 that is installed in the aircraft body 10 so as to surround the engine E. It is installed in a window hole 31 drilled in the front of the cooling fan F so as to cover the window hole 31, so as to safely guard the honeycomb-shaped core of the radiator R. The outside air flowing into the radiator R during operation is limited to the outside air taken in from the air intake port 32 provided at a high position of the machine frame 30 as shown by arrow A, thereby preventing the intake of outside air containing a large amount of dust near the ground surface. However, in order to enable inspection of the radiator R or cleaning of the dustproof screen 40 installed on the front surface of the radiator R, the above-mentioned Usually, it is attached to the window hole 31 in a removable manner, or it is attached to the window hole 31 in the form of a door that can be opened and closed using a hinge 21.

By the way, the cleaning of the dustproof screen 40 on the front surface of the radiator R, which is carried out through the above-mentioned window hole 31, is usually done by removing the dustproof screen 40 assembled on the front surface of the radiator R. At this time, in addition to removing the cover 20, it is necessary to attach and remove the dustproof net 40, and the dust attached to the dustproof net 40 is removed from the dustproof net 40.
Most of the dust falls from the dustproof net 40 and falls into the vagina inside the machine frame 30 due to the shock when removing the zero, so there is a problem in that cleaning work is required to further remove the fallen dust.

In order to solve this problem, the above-mentioned window hole 31 is left open, and a dustproof screen 4 is installed on the inside surface of the window hole 31.
There is a method to remove the clogged dust by supporting the assembly so that it can swing freely and hitting the dustproof screen 40 from the outside to make it vibrate. Since it is away from the front of the radiator, there is a problem that the dustproofing effect is poor.

In addition, the radiator cover 20 provided in the window hole 31 described above is made of only a frame frame, the dustproof net 40 is attached and supported on the inside thereof, and the radiator cover consisting of only the frame frame is rotated to open, so that the dustproof net can be attached to the radiator. There is also a known method for allowing the dust to come out of the room, but this method not only makes the dustproof screen far away from the front of the radiator, which not only does not improve the dustproof effect on the radiator core, but also prevents the dustproof screen from coming out of the room. There is a problem that removing dust from the screen becomes troublesome.

The purpose of the present invention is to solve these problems, and to place the dustproof net 40 provided on the front side of the radiator R on the inner side of the radiator cover 20, which freely opens and closes the window hole 31 made on the front side of the radiator chamber of the machine frame 10. When the radiator cover 20 is opened, the radiator cover 20 is installed so that it comes out of the radiator room together with the radiator cover 20, and when the radiator cover 20 is closed, it comes into close contact with the front of the radiator R. The object of the present invention is to propose a new method that, when pulled out of the radiator room together with the 20, can vibrate and easily remove dust by simply tapping it.

A radiator cover for a harvester or the like according to the present invention, which is a distant relative of this purpose, is attached to the body 10 of the harvester or the like so as to open and close the front of the radiator R of the engine E mounted on the body 10 of the harvester. A dustproof net 40 is supported on the inner surface side of the radiator cover 20 to be installed so as to be able to move forward and backward with respect to the radiator cover 20, and in a direction in which the dustproof net 40 is brought into close contact with the front surface of the radiator R when the radiator cover 20 is in a closed state. This structure is characterized by interposing a spring 42 that pushes out the air.

In this invention, the support means for supporting the dustproof net 40 on the inner surface of the radiator cover 20 so that it can move forward and backward relative to the front surface of the radiator R may be designed as appropriate.

In the illustrated embodiment, support rods 41 projecting outward are provided at the four corners of the dustproof screen 40, and the outer ends of the support rods 41 are attached to the slider provided on the radiator cover 20. A spring 42 is provided between the radiator cover 20 and the dustproof net 40, which is slidably inserted into the movable tube 22, supported on the inner surface of the cover 20, and pushes out the net 40 toward the radiator R side. By fixing the dustproof net 40 in the closed position, the dustproof net 40 is brought into close contact with the front surface of the radiator R. The spring 42 is formed into a coil spring that can support the weight of the dustproof net 40, and the spring is used to support the dustproof net 40. You may also do so.

In the illustrated embodiment, the member indicated by reference numeral 33 in FIG. 1 is a locking tool that also serves as a handle when opening and closing the radiator cover 20, which can be opened and closed like a door. The member indicated by reference numeral 34 is a locking tool for locking the removable radiator cover 20 in the closed state, and 43 is a dust receptacle provided on the outer surface of the lower edge of the dustproof screen 40.

Next, to explain the function and effect, according to the means of the present invention configured as described above, when the radiator cover 20 is in the closed state, a support is provided inside the radiator cover 20 so as to be able to move forward and backward with respect to the radiator cover 20. spring 4
The dustproof net 40 pushed out by the spring 42 comes into close contact with the front surface of the radiator R and is attached to the front surface of the radiator R, so that the dustproof effect on the core of the radiator R is improved. .

Furthermore, when the radiator cover 20 is opened, the dustproof net 40 is pulled out of the radiator room together with the radiator cover 20, and in the pulled out state, the dustproof net 40 can be tapped lightly. Since the dustproof net 40 is vibrated by the spring 42 mentioned above, the dust clogged in the dustproof net 40 can be easily removed, and the dropped dust can fall out of the radiator chamber. Become.

Therefore, according to the present invention, the dustproof screen is provided in close contact with the front of the radiator to improve the dustproofing of the radiator, and the dustproof screen can be easily pulled out of the radiator room, and moreover, the dust can be removed by just tapping it lightly. You will be able to drop it.
