It will be self-evident to those who have knowledge.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the attached FIGS. 1 to 5, but the description will focus on the parts necessary for understanding the operation and action according to the present invention.

Prior to the description of the drawings, in describing the agricultural work vehicle according to the embodiment of the present invention, a cabin type tractor in which a driving seat is surrounded by a cabin will be described as an example, but the present invention is a cabin type tractor. It is not limited to tractors, and it can be applied to non-cabin type tractors or other agricultural work vehicles that do not apply cabins.

First of all, referring to FIG. 1, an agricultural work vehicle according to an embodiment of the present invention includes a bonnet, a radiator 12, an air cleaner support 13, an air cleaner 14, an intercooler 15, an oil cooler 16, and a fuel cooler. (17), a blocking plate (18) and an insect repellent filter (19).

The bonnet forms an external shape of an engine room of an agricultural work vehicle.

In addition, an engine room in which an engine and various parts of an agricultural work vehicle are mounted is provided in the bonnet. An engine (not shown) is placed at the rear of the engine room, and the engine may be a diesel engine.

A radiator 12 is installed in the engine room. The radiator 12 is installed in front of the engine and cools by circulating coolant. A water jacket is installed around a cylinder inside the engine, and the engine is cooled by circulating coolant therein. If the coolant is left as it is, it boils and cannot be cooled. Because of this, the heated cooling water is circulated to the radiator 12 to be cooled.

An air cleaner support 13 is installed in front of the radiator 12 . The air cleaner support 13 may be formed and installed in a square frame shape around the front of the radiator 12 .

The air cleaner 14 is fixed and supported on the air cleaner support 13. The air cleaner 14 is configured to prevent abrasion of cylinders by removing dust or soil in the air sucked into the engine, and to prevent noise generated when air is sucked into the cylinder.

There are two types of air cleaners (14), wet and dry. In the wet type, oil is contained at the bottom of the air cleaner (14), so that the sucked air collides with the oil surface and removes dust when changing direction. configuration to remove. On the other hand, in the dry type, a filter medium such as filter paper or wire mesh is installed in the air cleaner 14 to remove dust introduced into the air cleaner 14 .

Meanwhile, an intercooler 15 is installed in front of the radiator 12 . More specifically, a condenser for condensing the refrigerant of a cooling/heating air conditioner is installed in front of the radiator 12, and an intercooler 15 is installed above the condenser. The intercooler 15 serves as a cooler to increase air density by cooling the air drawn into the engine room.

An oil cooler 16 is installed in front of the intercooler 15. The oil cooler 16 is a device that cools the temperature of the engine oil step by step, and the temperature of the engine oil becomes very high in continuous operation at high rotation and high load, and the overheated oil not only does not properly lubricate, but also the oil itself. may also be altered. To this end, the engine oil is cooled through the oil cooler 16 .

A fuel cooler 17 is installed in front of the oil cooler 16 . The fuel cooler 17 cools heat generated by vaporization of fuel.

Meanwhile, the blocking plate 18 is installed along the sides of the radiator 12 and the intercooler 15 . The blocking plate 18 can block the space between the radiator 12 and the intercooler 15 and is inclined toward the inside of the engine room.

External air is introduced into the radiator 12 so that the radiator 12 can be cooled. At this time, if too much outside air flows into the radiator 12, the cooling efficiency of the radiator 12 decreases. To this end, by installing the blocking plate 18 between the radiator 12 and the intercooler 15, it is possible to minimize the inflow of a lot of air into the radiator 12 at once.

In addition, air introduced between the radiator 12 and the intercooler 15 may cool the intercooler 15 . At this time, the intercooler 15 is a device that is greatly affected by temperature, and the operating performance of the intercooler 15 does not improve only when the intercooler 15 is unconditionally cooled. Therefore, an effect of minimizing the limitation of the operating performance of the intercooler 15 may be obtained by partially blocking the inflow of air by the blocking plate 18 .

In other words, the blocking plate 18 induces proper cooling of the intercooler 15 and the radiator 12 and can prevent the intercooler 15 and the radiator 12 from deteriorating their operating performance.

An insect repellent filter 19 is installed in the blocking plate 18 . The insect repellent filter 19 is configured to filter out dust or foreign substances sucked into the engine room.

On the other hand, the insect repellent filter 19 is configured to be separable inside the blocking plate 18. To this end, one end of the blocking plate 18 is fixed to the radiator 12, and the other end of the blocking plate 18 is rotated to the left or right, which is the direction away from the engine room, around the fixed one end (Fig. Refer to the direction axis of 1) It is configured to open and close the inside of the blocking plate 18.

Referring back to FIG. 1 , in the agricultural work vehicle of the present invention, a battery installation portion, which is a predetermined space in which a battery (not shown) is installed in front of the fuel cooler 17, is formed.

Referring back to FIGS. 1 and 2 , in the engine room, a support bracket 20 extending upward from the bottom surface in front of the intercooler 15 to which the oil cooler 16 is mounted is installed.

More specifically, the support bracket 20 includes a first bracket 22 and a second bracket 24 . The first bracket 22 is coupled to the upper side of the oil cooler 16 and formed in a reverse U-shape surrounding the oil cooler 16 . In addition, the second bracket 24 is formed by extending from both sides of the first bracket 22 adjacent to the bottom surface in a direction away from the intercooler 15 (refer to the direction axis of FIG. 1_hereafter assumed to be forward), , the lower sides of the oil cooler 16 and the fuel cooler 17 are fixed at the same time.

In particular, the first bracket 22 and the upper side of the oil cooler 16 are coupled with butterfly bolts 25. When the butterfly bolt 25 is released, the upper and side surfaces of the oil cooler 16 are not coupled anywhere. For this reason, as shown in FIG. 3 , when the binding state between the first bracket 22 and the oil cooler 16 is released, the lower side of the oil cooler 16 and the fuel cooler 17 is fixed to the second bracket 24. In this state, the intercooler 15 may be tilted forward, which is a direction away from the intercooler 15.

To this end, a bracket-side bolt installation portion 265 in which a butterfly bolt 25 is installed is formed on the upper side of the first bracket 22, and through the bracket-side bolt installation portion 265 on the upper side of the oil cooler 16. An oil cooler side bolt installation portion 165 in which a lower end of the installed butterfly bolt 25 is inserted and mounted may be formed.

Meanwhile, referring to FIGS. 2 and 4 , the other end of the blocking plate 18 that is not fixed to the radiator 12 must be fixed to the other end of the blocking plate 18 so that the blocking plate 18 is not opened. To this end, a blocking plate-side fixing part 115 extending toward the support bracket 20 while surrounding the outermost end of the intercooler 15 is installed at the other end of the blocking plate 18 . Correspondingly, a bracket-side fixing part 225 may be installed on the side of the support bracket 20, in contact with the blocking plate-side fixing part 115, and to which another butterfly bolt 25 may be installed.

More specifically, when the butterfly bolt 25 is installed in a state where the blocking plate-side fixing part 115 and the bracket-side fixing part 225 are in contact with each other, the other end of the blocking plate 18 is fixed, so that the blocking plate 18 is intercooler ( 15) and the radiator 12 are sealed. Unlike this, when the butterfly bolt 25 connecting the blocking plate-side fixing part 115 and the bracket-side fixing part 225 is released, one end of the blocking plate 18 is fixed to the radiator 12, so the other end As this free end, the other end of the blocking plate 18 rotates in a direction away from the engine room, opening the space between the radiator 12 and the intercooler 15.

On the other hand, the agricultural work vehicle of the present invention has a structure in which cleaning is easily arranged. The cleaning process of the agricultural working vehicle of the present invention will be described with reference to the drawings below.

First open the bonnet. Thereafter, the butterfly bolt 25 binding the first bracket 22 of the support bracket 20 and the oil cooler 16 is released to tilt the oil cooler 16 and the fuel cooler 17 forward. As the oil cooler 16 and the fuel cooler 17 are tilted forward, the intercooler 15 located behind the oil cooler 16 and the fuel cooler 17 can be cleaned more easily.

Thereafter, another butterfly bolt 25 connecting between the blocking plate-side fixing part 115 and the bracket-side fixing part 225 is released to rotate the blocking plate 18 left and right. The blocking plate 18 rotates to open the inside of the blocking plate 18, and the insect repellent filter 19 inside the opened blocking plate 18 is separated from the engine room. That is, since the insect repellent filter 19 located in front of the radiator 12 is removed, the radiator 12 can be easily cleaned.

Meanwhile, the intercooler 15 and the radiator 12 may use any one of a method of removing dust or foreign matter on the surface by spraying high-pressure water or gas to the intercooler 15 or the radiator 12.

When the cleaning is completed, assemble the insect repellent filter (19) to its original position, and assemble the blocking plate side fixing part 115 and the bracket side fixing part 225 so that the blocking plate 18 is connected to the intercooler 15 and the radiator 12. to seal between them. Thereafter, the oil cooler 16 and the fuel cooler 17 are pushed in the direction of the intercooler 15, and the first bracket 22 of the support bracket 20 and the upper side of the oil cooler 16 are assembled with butterfly bolts 25. Cleaning ends when the bonnet is closed.

In the above, preferred embodiments of the present invention have been described by way of example, but the scope of the present invention is not limited only to these specific embodiments, and can be appropriately changed within the scope described in the claims.
