Description

[Detailed description of the invention] This invention allows the collection of grass, straw, etc. to be carried out using a collection device attached to the front of the agricultural vehicle, and the fine dust, etc. that fly up to the front of the engine cover can be removed. To provide a dust prevention device for an agricultural vehicle, which prevents air from being sucked in through a cooling air intake window and attached to a radiator, causing overheating, and allowing agricultural work to continue for a long period of time in good conditions.

2. Description of the Related Art Conventionally, as part of agricultural work, many collection agricultural works have been carried out in which grass and straw collected in fields are appropriately collected using a collecting device such as a harvester mounted on the front part of a farming vehicle.

By the way, in the case of conventional agricultural vehicles, a cooling air intake window was always opened in the front of the engine cover that housed the radiator, and this was because the cooling air intake window was not equipped with a dust prevention device. When the above-mentioned agricultural collection work is carried out, the fine dust and other particles that fly up in the surrounding area are quickly sucked in through the cooling air intake window and adhere to the radiator, drastically reducing the cooling effect and causing overheating. In addition, since the front of the engine cover cannot be opened and closed freely, once fine dust, etc. adheres to the radiator, it is impossible to continue collecting agricultural work for a long period of time. However, there are drawbacks that require a lot of time and effort, and there is a strong need for a solution to this problem.

In view of the above, and in order to quickly solve the above-mentioned drawbacks of the conventional technology, the present invention has been developed by opening a cooling air intake window in the front surface of the engine cover of an agricultural vehicle in which a radiator is housed, and The dust-proof body is pivoted on an upper pivot shaft, has an adsorption magnet at the bottom, has a dust-proof net stretched over its surface, and has a triangular shape when viewed from the side. The structure is designed to be able to open and close freely, making it easier to carry out long-term collection work by reliably preventing fine dust generated during agricultural work collecting grass and straw from being sucked in through the cooling air intake window and adhering to the radiator. Of course, the dust-proof body has a triangular shape to expand the intake area, minimize the adhesion of fine dust, etc., and at the same time achieve the purpose of facilitating cleaning of the radiator. The purpose was to provide a dust prevention device for agricultural vehicles,
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the apparatus of the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes an agricultural vehicle, and the agricultural vehicle 1 is equipped with an engine cover 2 at the front, a loading platform 3 at the rear, and has a large number of driven and rotated running wheels 14 mounted on an axle. ing. A cooling air intake window 4 of an appropriate size is provided at the front of the engine cover 2, and a radiator 5 and a cooling fan 6 are provided inside the engine cover 2 at the rear.

The cooling air intake window 4 has an engine cover 2
The upper part is pivotally supported by a pivot shaft 8 to bearing fittings 13, 13 attached to the upper front surface of the , an adsorption magnet 9 is provided in the center of the lower part, and a dustproof net 10 is stretched over the surface, and the whole is oriented sideways. Dustproof body 7 shaped like a triangle when viewed from above
are provided so that they can be opened and closed about pivot shafts 8, 8.

An airtight packing 11 is attached to one of the parts of the engine cover 2 and the dustproof body 7 that are in close contact with each other to prevent fine dust from entering. Reference numeral 12 denotes a metal fitting to which the attraction magnet 9 is attracted, and this metal fitting 12 is provided at the lower part of the front side of the engine cover 2.

Note that if the dustproof body 7, which has a triangular shape as a whole when viewed from the side, is formed with the upper side shorter than the lower side, the dust removal screen 1
The amount of fine dust adhering to 0 can be significantly reduced.

Next, the operation of the present invention will be explained.

Now, the cooling air intake window 4 opened on the front side of the engine cover 2 is kept in close contact with the dustproof body 7 whose upper part is supported by a pivot shaft 8 and whose lower part is attached to a metal fitting 12 by an adsorption magnet 9. If the agricultural work of collecting grass, straw, etc. is carried out as the agricultural vehicle 1 moves forward,
Engine cover 2 due to the progress of the above collection agricultural work
Fine dust, etc. flying up to the front side is removed by the cooling fan 6.
Due to the suction effect, the cooling air is drawn into the radiator 5 along with the cooling air from the cooling air intake window 4. However, the cooling air intake window 4 has a dustproof screen 1 on its surface.
Since the dustproof body 7, which has a triangular shape as a whole and is stretched from the side, is placed in close contact with the pivot shaft 8 and the attracting magnet 9, all fine dust, etc. that try to be sucked in will be absorbed. Only the cooling air received by the dustproof net 10 is sucked into the radiator 5 side, and the radiator 5 is efficiently cooled. Therefore, no matter how long the agricultural work of collecting pasture grass, straw, etc. is continued, fine dust etc. will not adhere to the radiator 5, so that the collecting agricultural work can be performed satisfactorily without overheating. Moreover, since the dustproof body 7 has a triangular shape when viewed from the side, the intake area is expanded and the required amount of cooling air is transferred to the cooling air intake window 4.
Not only can air be drawn in accurately from the triangle, fine dust etc. adhering to the dustproof net 10 located at the lower side of the triangle can be automatically dropped by the vibration action of the agricultural vehicle 1, so that the dust can be clogged with fine dust etc. You can prevent this from happening. When cleaning the radiator 5 and the dustproof body 7, the dustproof body 7 is rotated clockwise about the pivot shaft 8 to the solid line position in FIG. 1 to open the cooling air intake window 4. Of course, it is sufficient to have the dustproof screen 10 cleaned.

In short, the present invention opens a cooling air intake window 4 on the front surface of the engine cover 2 of the agricultural vehicle 1 in which the radiator 5 is housed, and the upper part of the cooling air intake window 4 is pivotally supported by a pivot shaft 8. An adsorption magnet 9 is provided at the bottom, a dustproof net 10 is stretched over the surface, and the dustproof body 7, which is triangular in shape when viewed from the side, is provided so that it can be opened and closed about the pivot shaft 8, making it easy to carry out agricultural work. Even when the car 1 is used to collect grass, straw, etc., a lot of fine dust that flies up to the front side of the engine cover 2 enters the inside of the engine cover 2 through the cooling air intake window 4. The dustproof body 7 catches and prevents the dust from being sucked in and attached to the radiator 5, ensuring that no overheating phenomenon occurs, and making long-term collection farming easier. The dustproof body 7 uses a pivot shaft 8 and an adsorption magnet 9, perhaps because its triangular shape makes it possible to maximize the cooling air intake area and at the same time reduce the adhesion of fine dust. Since the cooling air intake window 4 can be easily covered or opened, the radiator 5 and the dustproof body 7 can be easily and quickly cleaned by anyone.
