Description

Combine {COMBINE}

The present invention relates to a combine provided with a condenser room for accommodating a condenser separately from the engine room.

Conventionally, as such a technique, as disclosed in Patent Literature 1, the space behind the lower part of the driving unit is divided into a lower engine room (in the literature, "engine bonnet") by a partition part ("ceiling plate" in the literature). In some cases, the engine was divided into an upper condenser room ("vibration-proof case") to accommodate the engine in the engine room, and the condenser (for air conditioning of the cabin) was accommodated in the condenser room.

According to the technique described in Patent Literature 1, since the condenser is disposed in the condenser room divided into the engine room and the partition portion, the condenser can exchange heat with air that is not affected by the exhaust heat of the engine, and the refrigerant cooling efficiency is improved. . In addition, since the condenser room is located above the engine room, dust such as rice straw is hard to reach the condenser room, and the dust is hardly attached to the condenser. As a result, the deterioration of the refrigerant cooling performance of the capacitor is unlikely to occur.

However, in the space adjacent to the gas left-right direction of a condenser room among the lower back of a driving part, various mechanisms, wiring, etc., such as a control system of a transverse conveyer, are often arrange | positioned, for example, and it is a technique of patent document 1, There is a limit to the size of the room in the gas left and right directions, and conversely, in order to secure a wide condenser room, there may be a case where a space for arranging various mechanisms cannot be sufficiently secured.

In view of the above circumstances, an object of the present invention is to provide a combine that can secure a condenser room widely in the horizontal direction of the body while also ensuring a sufficient space for arrangement of other mechanisms and the like.

The 1st characteristic structure of the combine which concerns on this invention is the cabin which covers a driving part, the engine room provided in the lower back of the said drive part, the condenser room provided above the said engine room, and the said engine room and the said condenser room. A partition portion partitioned up and down, a condenser arranged in the condenser room along the left and right directions of the gas, and the engine room and the convex surface along the front and rear directions so as to face the engine room and the condenser room, A hollow dust-proof cover having a thickness in the left and right directions of the condenser room and having an opening on the condenser room side, and having an opening on the condenser room side, the end of the condensing cover side of the condenser room, The condenser is placed in the dustproof cover so that the condenser is placed in the condenser room.

According to this configuration, part of the condenser enters the hollow space of the dust cover, so that the inner space of the dust cover can be used as the condenser room. In other words, it is possible to secure the condenser room widely in the left and right directions of the body by the thickness of the dustproof cover while ensuring sufficient space for arrangement of other mechanisms and the like.

A second feature of the combine according to the present invention is that the vertical wall facing the condenser room is spaced apart from the dustproof net of the dustproof cover in the dustproof cover, and is disposed outside the left and right directions of the condenser in a state in which the vertical wall facing the condenser room is spaced apart. I'm at the point.

For example, the amount of ventilation required for engine cooling may be larger than the amount of ventilation required by the condenser. According to this characteristic configuration, outside air introduced from a portion of the dustproof network that faces the condenser room does not directly enter the condenser room due to the obstacle of the vertical wall, and diffuses around the vertical wall. In particular, outside air diffused near the bottom of the vertical wall approaches the engine room below the condenser room. That is, most of the outside air which flowed in from the part which opposed the condenser room among the dustproof networks is guided to a vertical wall, and can flow into an engine room. Thus, with the simple structure of providing a vertical wall like this structure, it is possible to distribute the outside air from a dustproof cover at the ratio suitable for a condenser room and an engine room.

The 3rd characteristic structure of the combine which concerns on this invention is the point which extends the said partition part to the said vertical wall, and comprises the edge part of the said vertical wall side among the said partition parts so that ventilation is possible.

According to this characteristic structure, since the partition part extends to a vertical wall, the division degree of a capacitor | condenser room and an engine room becomes high, and invasion, such as dust to a condenser room, can be reduced. On the other hand, since the ventilation from the end part near the vertical wall of the division part is possible, it is possible to introduce the outside air diffused to the vicinity of the lower part of the vertical wall into the condenser room.

The 4th characteristic structure of the combine which concerns on this invention exists in the point which forms one or several opening hole in the edge part of the said vertical wall side among the said partition parts.

According to this characteristic structure, since the ventilation of the edge part of the vertical wall side of a division part is performed from the one or several opening hole formed in the edge part of the vertical wall side part of a division part, compared with the case where a large opening was formed, it is dust to a condenser room. Less invasion of the back

The fifth characteristic constitution of the combine according to the present invention is a point in which a heat sink that extends from the engine room and the condenser room to the grain tank disposed at the rear of the driving unit is provided over the width in the gas horizontal direction of the engine room. have.

Due to the structure of the combine, the engine room discharge heat is generated at the rear side of the gas, but if the condenser room is installed above the engine room, the heat of discharge from the engine room may rise between the grain tank and flow into the condenser room. . According to this configuration, the heat dissipation plate can prevent the exhaust heat from the engine room from entering the upper condenser room. In addition, the heat sink prevents dust, dust, and the like from being wound up from the package, and prevents condensation of the capacitor.

A sixth characteristic configuration of the combine according to the present invention is the condenser room, wherein the condenser fan is disposed adjacent to the rear side of the condenser, and the air cleaner is disposed along the gas left and right directions. It is located in the front side of the said condenser so that the center of gravity may be located on the rotating shaft center of the said fan.

According to this characteristic structure, since the air cleaner is arrange | positioned at the front side of a condenser in a condenser room, the outside air which flowed into the condenser room is introduce | transduced into a condenser while riding the outer peripheral part of an air cleaner. As a result, convection occurs between the air cleaner and the condenser, and part of the dust contained in the outside air falls off, and clogging of the condenser is reduced.

However, if the air cleaner is disposed on the front side of the condenser, there is a fear that the airflow to the condenser is impaired. However, in this structure, the air cleaner is arrange | positioned so that the center of an air cleaner may be located on the rotating shaft center of a fan. Since a fan motor is disposed at the rotational center of the fan, air flow is relatively small in the first place on the rotation axis of the fan. That is, as in this configuration, by arranging the air cleaner centered on the rotary shaft center of the fan with less air flow, the influence on the amount of ventilation to the condenser is suppressed as low as possible, thereby preventing the condenser from being blocked. The fall of a function can be reduced.

A seventh feature of the combine according to the present invention includes a swing shaft in a gas front-rear direction below the dust cover, wherein at least a portion of the dust cover side swings around the swing shaft together with the dust cover. It is comprised so that a support member which supports the lower end part of the said capacitor | condenser may be provided, and the part of the said dustproof cover side among the said support members is located above the part on the opposite side to the said dustproof cover of the said support member. I'm at a point.

According to this configuration, when the dust cover is swinged outward to open the engine room and the condenser room, part of the compartment can be removed at the same time, so that the engine room can be easily checked from above and the condenser room can be easily checked from below. Lose.

As described above, when a part of the condenser enters the dustproof cover, the support member is also disposed close to the side of the dustproof cover. And since the swing shaft is provided below the cabin, when the part of the dustproof cover side is rocked around the swing shaft, the swing trajectory protrudes above the partition, and a part of the partition which swings is supported. There is a fear of interfering with the part of the dustproof cover side in the member. However, in this structure, since the part of the dustproof cover side of a support member is located above the part on the opposite side to the said dustproof cover of the said support member, when the part of the dustproof cover side of a partition part oscillates around a rocking shaft, It is possible to prevent the swinging end of the partition from interfering with the support member.

The eighth feature structure of the combine which concerns on this invention is that the bottom face of the part of the said dustproof cover side among the said support members is located above the oscillation trace around the oscillation axis of the part of the said dustproof cover side among the said division parts, The said dustproof cover side part among the said support members is a point spaced apart upwards from the said partition part.

According to this characteristic structure, it can prevent that the oscillating end part of a partition part interferes with the bottom face of a support member by the simple structure which separates the part of the dustproof cover side upward from a partition part among support members.

A radiator fan 24 is disposed between the engine 22 and the radiator 23. By driving the radiator fan 24, outside air is introduced into the engine room 21 through the dustproof cover 41, and the radiator 23 and the engine 22 are cooled. The rear part of the engine room 21 is largely opened toward the rear grain tank 5 side, and the outside air which has the heat after cooling of the radiator 23 etc. is discharged | emitted from the rear part of the engine room 21 to the outside.

[About capacitor room]

The condenser room 31 is provided above the engine room 21 and behind the driver's seat 71 as shown in FIG. 3 and FIG. 4. The condenser room 31 and the engine room 21 are divided up and down by the partition plate 33 as a "compartment part" according to the present invention. That is, the partition plate 33 constitutes the bottom face of the condenser room 31 and the top face of the engine room 21.

The partition plate 33 is provided in the horizontal state on the upper part of the door-shaped frame 1a etc. which were set up on the base frame 1, and the like. The partition plate 33 is located on the rearward extension of the horizontal portion of the seat support 77. The driving unit 7 and the condenser room 31 are partitioned by the rear plate 78 and the upper plate 79 behind the driving seat 71. That is, the back plate 78 constitutes the front surface of the condenser room 31, and the upper plate 79 constitutes the upper surface of the condenser room 31.

The rear plate 78 is installed vertically from the rear end of the seat support 77. The upper plate 79 extends rearward from the upper end of the rear plate 78. The rear end of the upper plate 79 is bent upward to constitute the support frame 86 integrally, and the rear chassis 84 is provided on the support frame 86.

As shown in FIG. And the gas are arranged adjacent to the left and right directions.

The condenser room 31 is provided with the condenser 92 mentioned above, the condenser fan 93 arrange | positioned adjacent to the rear of the condenser 92, and the air cleaner 32, as shown to FIG. 4 and FIG. Doing. The capacitor | condenser 92 is arrange | positioned with the condenser fan 93 at the rear part of the condenser room 31 in the attitude | position along the gas left-right direction. The upper end of the condenser 92 is attached to the support frame 86 via the upper stay 35. The lower end part of the condenser 92 is provided in the upper part of the door frame 1a with the partition plate 33 via the lower stay 36 (refer FIG. 8).

The fan motor 94 is connected to the center of the grain tank 5 side among the condenser fans 93. The condenser fan 93 is driven to rotate around the rotation shaft center M by the driving of the fan motor 94. By the rotational drive of the condenser fan 93, a gap between the dustproof cover 41 and the inner circumference of the rear end of the condenser 92 and the condenser room 31 (both sides of the upper stay 35 and the like (see FIGS. 4 and 5). Outside air is introduced into the condenser room 31, and the refrigerant in the condenser 92 is cooled by the outside air. Like the rear part of the engine room 21, the rear part of the condenser room 31 is also largely opened to the rear grain tank 5 side, and the outside air which has the heat after cooling a refrigerant | coolant is the rear of the condenser room 31. It is discharged from the outside to the outside.

Thus, since the condenser 92 is arrange | positioned in the condenser room 31 different from the engine room 21, the condenser 92 is not influenced by the exhaust heat of the engine 22. As shown in FIG.

4 and 6, the condenser 92 allows the end portion of the dustproof cover 41 side to enter the dustproof cover 41 from the above-described opening. Thus, by using the internal space of the dustproof cover 41 as the condenser room 31, the opening / closing lever 74, the air volume control lever 75, the discharge clutch lever 76, the auger operating system, other wiring, etc. are arrange | positioned. It is possible to secure the condenser room 31 widely in the left-right direction of the body by the thickness of the dustproof cover 41 while ensuring a sufficient space.

Moreover, since a part of the internal space of the dustproof cover 41 was introduced into the condenser room 31, the partition plate 33 also extends to the inside of the dustproof cover 41 by that much.

The air cleaner 32 is connected with the precleaner 11 (refer FIG. 2, FIG. 3) provided in the right rear part of the roof part 81 through the duct 32b, and is filtered by the precleaner 11. As shown in FIG. Purify the outside air. The duct 32b is supported by the support frame 86 via the support bracket 32c, as shown to FIG. 3, FIG.

As shown in FIG. 5 and FIG. 6, the air cleaner 32 is substantially cylindrical shape, and is arrange | positioned at the front side of the condenser 92. As shown in FIG. The air cleaner 32 is mounted on the pedestal 32a disposed above the partition plate 33 in a posture along the gas left and right directions. The pedestal 32a is set high so that the center N of the air cleaner 32 may be located on the rotation shaft center M of the condenser fan 93.

Thus, since the air cleaner 32 is arrange | positioned at the front side of the condenser 92, the outside air (refer FIG. 6) which flowed into the condenser room 31 through the dustproof cover 41 is shown by the arrow in FIG. As described above, the air cleaner 32 is introduced into the condenser 92 while following the shape of the outer peripheral portion of the air cleaner 32. As a result, convection occurs between the air cleaner 32 and the condenser 92, and part of the dust contained in the outside air falls off, and clogging of the condenser 92 is reduced.

In addition, a fan motor 94 is disposed at the center of rotation of the fan, and on the rotation shaft center M of the condenser fan 93, where the air flow is relatively small in the first place, the center of the air cleaner 32 is N. Since it is arrange | positioned so that it may be located on the rotation shaft center M of the condenser fan 93, even if the air cleaner 32 is arrange | positioned in the front side of the condenser 92, ventilation to the condenser 92 will not be inhibited. In addition, the condenser fan 93 corresponds to the "fan" which concerns on this invention.

[About adjustment of ventilation amount of outside air]

As shown to FIG. 4 and FIG. 6, in the inside of the dustproof cover 41, the condenser room 31 is opposed to the condenser room 31 in the position left-right outside of the edge part of the dustproof cover 41 side of the condenser 92. The air volume adjusting plate 46 as the "vertical wall" is disposed in a posture along the body front-back direction and in a state spaced apart from the dustproof network 43.

As mentioned above, the partition plate 33 extends to the inside of the dustproof cover 41, and connects the outer end of the extended part with the lower end of the air volume control plate 46. In addition, the front end of the air volume control plate 46 is folded on the condenser room 31 side, and the part is connected to the rear end of the shielding plate 45 described above. In addition, the other location of the air volume adjusting plate 46 is fixed to the inner surface of the outer frame 42 suitably.

The shape of the air volume adjusting plate 46 is set to a level slightly smaller than the shape seen from the side surface of the condenser room 31. Therefore, the outside air introduced into the dustproof cover 41 through the dustproof net 43 becomes a obstacle and the airflow rate adjusting plate 46 is not directly introduced into the condenser room 31. It diffuses and flows into the condenser room 31. In particular, the outside air diffused near the lower portion of the airflow control plate 46 can flow into the engine room 21. That is, in the case where the amount of ventilation required for cooling the engine 22 is larger than the amount of ventilation required by the condenser 92, the outside air from the part of the dustproof cover 41 facing the condenser room 31, The air volume adjusting plate 46 can also be distributed to the engine room 21 using the guide.

Moreover, the edge part of the partition plate 33 vicinity of the airflow volume adjustment board 46 is comprised by the mesh-shaped ventilation net 34. As shown in FIG. Therefore, ventilation to the condenser room 31 from the lower part of the airflow volume adjustment board 46 is possible, and intrusion of dust etc. into the condenser room 31 is reduced. Therefore, for example, when the engine 22 does not require a large amount of ventilation, or when the condenser 92 also requires a large amount of ventilation, it is possible to appropriately distribute the condenser room 31. In this way, only the air volume adjusting plate 46 is provided, so that the outside air from the portion of the dustproof cover 41 that faces the condenser room 31 is suitable for the engine room 21 and the condenser room 31 depending on the situation. Can be distributed in proportions.

[About heat radiation plate]

As shown in FIG. 1, FIG. 5, and FIG. 8, the heat dissipation plate 38 as a "heat sink" which extends between the engine room 21 and the condenser room 31 to the grain tank 5 is engine room 21 It is provided over the width of the gas left-right direction. In detail, as shown in FIG. 8, the angle member 37 is provided in the upper back surface of the sentence frame 1a, and the heat radiation plate 38 is bolted to the upper surface of the angle member 37. As shown in FIG. . The heat dissipation plate 38 makes it possible to prevent the exhaust heat from the engine room 21 ascending with the grain tank 5 to flow into the condenser room 31. In addition, since the outside air flows into the condenser room 31 from the rear of the condenser room 31 as well, the heat dissipation plate 38 also serves to prevent the exhaust wind from the engine room 21 from rising. Dirt, dust, and the like, which are wound up from the pavement by the wind, are introduced into the condenser room 31 to prevent clogging in the condenser 92. In addition, the heat radiating plate 38 is made into the shape which does not inhibit the opening-and-closing oscillation operation | movement of the grain tank 5. As shown in FIG.

[About opening and shutting fluctuation of dust cover]

Opening / closing fluctuations of the dustproof cover 41 will be described in detail. As described above, the dustproof cover 41 is capable of swinging around the swing shaft 47 as shown in FIGS. 4 and 7. In addition, the outer frame 42 includes a seat support 77 (including a driving seat 71), a movable portion 78a which is a lower portion of the rear plate 78, and a dustproof cover 41 side of the partition plate 33. The movable part 33b (including the ventilation net 34) is connected, and these members can also be rocked with the dustproof cover 41. As shown in FIG. Therefore, when the dust cover 41 swings open, not only the right side surfaces of the engine room 21 and the condenser room 31 are opened, but also the top and front surfaces of the engine room 21 and the bottom surface of the condenser room 31. A part and a part of the front surface are also opened, and it is easy to carry out maintenance work of the engine room 21 and the condenser room 31.
