Description

Combine {COMBINE}

The present invention relates to a combine having a condenser room for accommodating a condenser separately from an engine room.

Conventionally, as disclosed in Japanese Patent Application Laid-Open Publication No. 2002-328701, a space on the lower rear side of the operating portion is divided into a lower engine room ("engine bonnet" in the literature) and a lower engine room , And an upper-side condenser room (a "dustproof case" in the literature) to house the engine in the engine room and accommodate a condenser (for air conditioning of the cabin) in the condenser room.

According to the technique described in Patent Document 1, since the condenser is disposed in the condenser room partitioned by the engine room and the partition, the condenser can perform heat exchange with the air that is not influenced by the exhaust heat of the engine, and the refrigerant cooling efficiency is improved . Further, since the condenser room is located on the upper side of the engine room, dust such as rice straw crumbs can hardly reach the condenser room, and the dust is hardly attached to the condenser. As a result, the refrigerant cooling performance of the condenser is hardly reduced.

However, in the lower rear portion of the operation portion, various mechanisms such as the operation system of the lateral conveying conveyor, wiring, and the like are often disposed in the space adjacent to the lateral direction of the body of the condenser room. In the technology of Patent Document 1, There is a limit in the size of the room in the lateral direction of the body and conversely there may be a case where sufficient space for arranging various mechanisms can not be secured enough to secure a large capacity of the condenser room.

SUMMARY OF THE INVENTION In view of the above-described circumstances, it is an object of the present invention to provide a combine capable of securing a large space in a capacitor chamber in a left-right direction and a space for arranging other mechanisms.

A first feature of the combine according to the present invention is a combine comprising a cabin for covering an operation part, an engine room provided at a rear lower side of the operation part, a condenser room provided above the engine room, A condenser arranged in the condenser room along the gas transverse direction; and a condenser disposed in the gas outboard side along the gas front-rear direction so as to face the engine room and the condenser room, And a dustproof cover having a hollow shape and having an opening at the condenser room side and having a thickness in the left and right direction of the body so as to allow the outside air to flow to the condenser room, wherein an end of the condenser, And the condenser is disposed in the condenser room.

With this feature, since a part of the condenser is put into the hollow space of the dust cover, the inner space of the dust cover can be used as the condenser room. In other words, it is possible to ensure a large capacitor room in the lateral direction of the body by the thickness of the dust cover, while securing a sufficient space for arranging other mechanisms and the like.

The second feature of the combine according to the present invention is that in the dustproof cover, the vertical wall facing the condenser room is disposed on the outer side of the casing in the lateral direction with respect to the casing so as to be spaced from the vibration- It is in point of doing.

For example, the amount of ventilation required for cooling the engine may be larger than the amount of ventilation required for the condenser. With this feature, the outside air flowing from the portion facing the condenser room of the vibration damping network is diffused to the periphery of the vertical wall without obstructing the vertical wall and directly flowing into the condenser room. In particular, the outside air diffused near the lower end of the vertical wall approaches the engine room on the lower side of the condenser room. That is, most of the outside air flowing in from the portion facing the condenser room of the vibration damping network can be guided to the vertical wall and flow into the engine room. As described above, with the simple structure that the vertical wall is provided like this structure, it is possible to distribute the outside air from the dustproof cover in a ratio suitable for the condenser room and the engine room.

The combine according to the third aspect of the present invention is characterized in that the partition is extended to the vertical wall and the end of the partition is allowed to be ventilated.

According to the present feature, since the dividing portion extends to the vertical wall, the degree of partition between the condenser room and the engine room is increased, and intrusion such as dust into the condenser room can be reduced. On the other hand, since the partition can be ventilated from the end near the vertical wall, it is possible to introduce the outdoor air diffused near the lower portion of the vertical wall into the condenser room.

The combine according to the fourth aspect of the present invention is characterized in that one or a plurality of openings are formed in the end portion of the partition wall on the side of the longitudinal wall.

With this feature, since the ventilation of the end portion on the longitudinal wall side of the partitioning portion is performed from one or a plurality of openings formed in the end portion on the longitudinal wall side of the partitioning portion, as compared with the case where a large opening is formed, And the like.

A combine according to a fifth aspect of the present invention is characterized in that a heat radiating plate extending from between the engine room and the condenser room to a grain tank disposed behind the operation section is provided over the width of the engine room in the left- have.

In the structure of the combine, the engine room exhaust heat is formed on the rear side of the gas chamber. However, when the condenser chamber is disposed on the upper side of the engine room, exhaust heat from the engine room rises between the gas tank and the condenser room, . With this feature, it is possible to prevent the exhaust heat from the engine room from entering the upper condenser room by the heat sink. Further, the heat sink prevents the dust, dust, and the like wound up from the package from entering the condenser room, thereby reducing clogging of the condenser.

The condenser according to the sixth aspect of the present invention is characterized in that in the condenser room, the condenser fan is disposed adjacent to the rear side of the condenser, and the air cleaner is arranged so as to follow the gas- Is disposed on the front side of the condenser so that the center of the condenser is located on the rotation axis of the fan.

According to this feature, since the air cleaner is disposed on the front side of the condenser in the condenser room, the outside air introduced into the condenser room is introduced into the condenser while riding the outer peripheral portion of the air cleaner. As a result, convection is generated between the air cleaner and the condenser, and a part of the dust contained in the outside air is removed to reduce clogging of the condenser.

However, if the air cleaner is disposed on the front side of the condenser, ventilation to the condenser may be hindered. However, in this configuration, the air cleaner is disposed so that the center of the air cleaner is positioned on the rotation axis of the fan. Since the fan motor is disposed in the rotation center of the fan, the flow of air is relatively small on the rotation axis of the fan. That is, by arranging the air cleaner in such a manner that the air cleaner is centered on the rotation axis of the fan having a relatively small flow of air, the influence on the amount of ventilation to the condenser is suppressed as low as possible, It is possible to reduce the deterioration of the function.

A seventh characterizing feature of the combine according to the present invention is that combiners have a swinging shaft in the forward and backward direction of the gas below the dustproof cover and at least a portion of the dividing portion on the dustproof cover side is swung around the swinging shaft And a support member for supporting the lower end of the condenser to the partition, wherein a portion of the support member on the side of the dust cover is positioned above the portion of the support member opposite to the dust cover, It is in point that it makes.

With this feature, when the engine room and the condenser room are opened by swinging the dust cover to the outside, a part of the compartment can be removed at the same time, so that it is easy to check the engine room from above and it is easy to check the condenser room from below Loses.

In addition, when a part of the condenser is put in the dust cover as described above, the support member is also arranged close to the dust cover. When the portion on the dust cover side of the partition is pivoted about the pivot shaft, the swing locus protrudes upward beyond the partition, and a part of the swinging partition is supported by the support There is a fear of interfering with the part of the member-side dust cover. However, in this configuration, since the portion of the support member closer to the dust cover is located above the portion of the support member opposite to the dust cover, when the portion of the partition member near the dust cover is pivoted about the pivot shaft , It is possible to prevent the swinging end portion of the partition portion from interfering with the support member.

A combine according to an eighth characterizing feature of the present invention is characterized in that the bottom surface of the portion of the support member on the side of the dustproof cover is located above the swing locus around the pivot axis of the portion of the partition on the dustproof cover side, And a part of the support member on the side of the dustproof cover is spaced upward from the partition.

According to this characteristic configuration, it is possible to prevent the swinging end portion of the partition portion from interfering with the bottom surface of the support member with a simple structure that the portion of the support member on the dust cover side is spaced upward from the partition portion.

[ An opening and closing lever 74 for operating the opening and closing shutter and an outlet clutch lever 76 for controlling the driving and stopping of the screw incorporated in the curled-feed conveying device 6, 4), an auger operation system (not shown) for turning operation of the lateral conveying conveyor 63 and a vertical swinging operation, and the like are arranged.

[About air conditioner]

In the combine according to the present invention, as shown in Fig. 3, an air conditioner 9 for performing air conditioning inside the cabin 8 is disposed. The air conditioner 9 includes an in-room unit 91, a compressor (not shown), a condenser 92, and the like. The indoor unit 91 is disposed on the front side portion of the inside of the ceiling of the cabin 8. Although not specifically shown, a sirocco fan, an evaporator, a heater and the like are built in the casing.

The compressor is disposed in the engine room 21, which will be described later, and is connected to the output shaft of the engine 22, although not particularly shown. The compressor is driven by the engine 22 to compress the refrigerant, and supplies the compressed refrigerant to the condenser 92.

The condenser 92 is disposed in a condenser room 31 to be described later. The refrigerant supplied from the compressor to the condenser 92 is cooled by heat exchange with the outside air introduced into the condenser room 31 through the dustproof cover 41 to be described later and is liquefied. The liquefied refrigerant is stored in the receiver 95 described later. While the refrigerant is stored in the receiver 95, the bubbles in the refrigerant are removed. Thereafter, the refrigerant is supplied to the evaporator.

[About dust cover]

A vibration isolating cover 41 for allowing air to flow in the engine room 21 and the condenser room 31 and preventing the intrusion of dust and dirt is provided on the right side of the cabin 8 And is disposed adjacent to the lower portion of the rear portion of the door 85. [

As shown in Fig. 4, the dust cover 41 is formed by attaching a dust-proofing net 43 to an outer frame 42 having an outer peripheral shape. As shown in Figs. 4 and 6, the outer frame 42 is formed in a U-shape in cross section, and the dustproof cover 41 has a hollow shape having a thickness in the lateral direction of the base. The engine room 21 of the outer frame 42 and the inner circumferential end of the condenser room 31 form an opening largely opened to the engine room 21 and the condenser room 31 side.

The lower portion of the dust cover 41 faces the engine room 21 as shown in Fig. 3, and the lower portion thereof follows the shape seen from the side of the engine room 21. As shown in Fig. On the other hand, the upper part of the dust cover 41 faces the condenser room 31, but the upper part thereof is larger than the shape seen from the side of the condenser room 31 (see FIG. 3). Therefore, the shielding plate 45 having the same shape as that of the opening portion larger than the shape seen from the side face of the condenser room 31 is fixed to the inner side of the outer frame 42 in the lateral direction of the base body. 6), and the lower end of the shield plate 45 is engaged with the dust cover (not shown) of the horizontal portion of the seat support 77 41). As a result, the shield plate 45 prevents the inside of the cabin 8 from being communicated with the outside through the dust-tightening network 43.

7, the dust cover 41 is provided around the pivot shaft 47 (see Figs. 1, 3, 4) provided in the lower portion of the dust cover 41, It is possible. The engine compartment 21 and the condenser room 31 are opened toward the right side of the base so that the engine room 21 and the condenser room 31 can be inspected.

[About engine room]

3 and 4, the engine room 21 is provided at the lower portion of the driver's seat 71 (lower rear portion of the operation portion 7), and the engine 22 is placed in the engine room 21 . 3, the seat support 77 has an inverted L-shaped cross section when viewed from the side, and the seat support 77 constitutes the upper surface and the front surface of the engine room 21 . The engine room 21 and the operation section 7 are partitioned by the seat support 77 so that the exhaust heat from the engine 22 is not transmitted to the cabin 8.

The engine room 21 is provided with a radiator 23 for cooling the engine 22 in a posture in the gas longitudinal direction and laterally outside the engine 22. A radiator fan (24) is disposed between the engine (22) and the radiator (23). By driving the radiator fan 24, the 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 portion of the engine room 21 is largely opened toward the rear grain tank 5 and the outside air having the heat after the cooling of the radiator 23 or the like is discharged from the rear portion 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 Figs. The condenser room 31 and the engine room 21 are partitioned vertically by a partition plate 33 as a "partition" according to the present invention. That is, the partition plate 33 constitutes the bottom surface of the condenser room 31 and constitutes the upper surface of the engine room 21.

The partition plate 33 is installed horizontally on the upper part of the door frame 1a installed upright on the base frame 1. The partition plate 33 is located on the rear extension of the horizontal portion of the seat support 77. The operation section 7 and the condenser room 31 are partitioned by the back plate 78 and the upper plate 79 at the rear of the operation seat 71. That is, the back surface 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 back surface plate 78 is vertically installed 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 portion of the upper plate 79 is bent upward to integrally constitute the support frame 86 and the rear chassis 84 is provided at the upper portion of the support frame 86. [

4 and 6, the opening / closing lever 74, the air volume adjusting lever 75, the discharging clutch lever 76, the auger operating system, the link mechanism related thereto, and the like are provided in the condenser room 31, And left and right sides of the body.

The condenser room 31 is provided with the condenser 92 described above and a condenser fan 93 disposed adjacent to the rear of the condenser 92 and an air cleaner 32 as shown in Figs. . The condenser 92 is disposed in the rear portion of the condenser room 31 with the condenser fan 93 in a posture along the gas transverse direction. The upper end of the condenser 92 is provided on the support frame 86 via the upper stay 35. [ The lower end of the condenser 92 is provided on the upper portion of the door frame 1a together with the partition plate 33 via the lower stay 36 (see FIG. 8).

A fan motor 94 is connected to the center of the condenser fan 93 on the side of the grain tank 5. The condenser fan 93 is rotationally driven around the rotary shaft M by driving the fan motor 94. [ The gap between the dustproof cover 41 and the inner circumference of the rear end of the condenser room 31 and the gap between the condenser 92 and the condenser room 31 (both sides of the upper stay 35 (see Figs. 4 and 5) ), Etc., the outside air is introduced into the condenser room 31, and the refrigerant of the condenser 92 is cooled by the outside air. The rear portion of the condenser room 31 is also largely opened to the side of the rear grain tank 5 in the same manner as the rear portion of the engine room 21. The outside air having the heat after cooling the refrigerant is returned to the rear of the condenser room 31 And is discharged to the outside.

Since the condenser 92 is disposed in the condenser room 31 different from the engine room 21 as described above, the condenser 92 is not affected by the exhaust heat of the engine 22.

4 and 6, the condenser 92 allows the end on the side of the dust cover 41 to enter the inside of the dust cover 41 from the opening described above. By using the internal space of the dust cover 41 as the condenser room 31 as described above, the opening / closing lever 74, the air volume adjusting lever 75, the discharging clutch lever 76, the auger operating system, It is possible to secure the condenser room 31 wide in the gas transverse direction by the thickness of the dust cover 41. [

Since a part of the inner space of the dust cover 41 is introduced into the condenser room 31, the partition plate 33 extends to the inside of the dust cover 41 as much.

The air cleaner 32 is connected to the pre-cleaner 11 (see FIGS. 2 and 3) provided at the right rear portion of the loop portion 81 through a duct 32b, Thereby further purifying the outside air. The duct 32b is supported by the support frame 86 through the support bracket 32c as shown in Figs.

As shown in Figs. 5 and 6, the air cleaner 32 has a substantially cylindrical shape and is arranged on the front side of the condenser 92. Fig. The air cleaner 32 is mounted on and fixed to a pedestal 32a disposed at an upper portion of the partition plate 33 in a posture in the lateral direction of the body. The pedestal 32a is set to be high so that the center N of the air cleaner 32 is positioned on the rotation axis M of the condenser fan 93. [

Since the air cleaner 32 is disposed on the front side of the condenser 92 as described above, the outside air (see FIG. 6) that has flowed into the condenser room 31 through the dust cover 41, The shape of the outer circumferential portion of the air cleaner 32 is introduced to the condenser 92 with a certain degree. As a result, convection occurs between the air cleaner 32 and the condenser 92, and a part of the dust contained in the outside air is removed to reduce the clogging of the condenser 92.

A fan motor 94 is disposed in the rotation center portion of the fan and the center N of the air cleaner 32 is located at a position where the flow of air is relatively small on the rotation axis M of the condenser fan 93 Even if the air cleaner 32 is disposed on the front side of the condenser 92, ventilation to the condenser 92 is hardly inhibited. The condenser fan 93 corresponds to the "fan" according to the present invention.

[About adjustment of quantity of ventilation of outside air]

4 and 6, a portion of the inside of the dust cover 41 which is opposite to the condenser room 31 is located at a position outside the side of the dust cover 41 side of the condenser 92, The air volume adjusting plate 46 as the "vertical wall" is disposed in a posture along the gas longitudinal direction and in a state of being spaced apart from the vibration damping net 43.

As described above, the partition plate 33 extends to the inside of the dust cover 41, and connects the outer end of the extended portion to the lower end of the air volume adjusting plate 46. The front end portion of the air volume adjusting plate 46 is folded to the side of the condenser room 31 and the portion is connected to the rear end portion of the shielding plate 45 described above. Further, other portions of the air amount adjusting plate 46 are appropriately fixed to the inner surface of the outer frame 42.

The shape of the air volume adjusting plate 46 is set to be slightly smaller than the shape seen from the side face of the condenser room 31. Therefore, the outside air introduced into the dust cover 41 through the dust cover 43 does not directly flow into the condenser room 31 due to the air volume adjusting plate 46 being obstructed, And is then introduced into the condenser room 31. Particularly, the outside air diffused into the vicinity of the lower portion of the air amount adjusting plate 46 can flow into the engine room 21. That is, when 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 portion of the dustproof cover 41 opposed to the condenser room 31, It is possible to distribute it to the engine room 21 using the air volume adjusting plate 46 as a guide.

The end of the partition plate 33 near the air volume adjusting plate 46 is formed by a mesh net 34 of a meshed shape. Therefore, it is possible to allow the air to flow from the vicinity of the lower portion of the air amount adjusting plate 46 to the condenser room 31, and at the same time to reduce the intrusion of dust or the like into the condenser room 31. Therefore, for example, it is possible to properly distribute to the condenser room 31 when the engine 22 does not require a large amount of ventilation or when the condenser 92 also requires a large amount of ventilation. The outside air from the portion of the dust cover 41 opposed to the condenser room 31 can be sucked into the engine compartment 21 and the condenser room 31 depending on the situation Quot; < / RTI >

[About heat dissipation plate]

The heat radiating plate 38 serving as a "heat sink" extending from between the engine room 21 and the condenser room 31 to the grain tank 5 is connected to the engine room 21 as shown in FIGS. 1, 5, In the lateral direction of the base body. 8, an angle member 37 is provided on the upper back surface of the door frame 1a, and a heat radiating plate 38 is bolted to the upper surface of the angle member 37 . The heat dissipation plate 38 can prevent the exhaust heat from the engine room 21 from rising to the grain tank 5 and flowing into the condenser room 31. [ Since the outside air flows into the condenser room 31 from the rear of the condenser room 31 and the heat radiating plate 38 also serves to prevent the exhaust air from the engine room 21 from rising, It is also possible to prevent dust or dust from being wrapped up from the package on the wind in the condenser room 31 and clogging the condenser 92. The heat dissipating plate 38 is shaped so as not to hinder the opening and closing swinging operation of the grain tank 5.

[About opening / closing movement of dust cover]

The opening / closing movement of the dust cover 41 will be described in detail. As described above, the dust-proof cover 41 is swingable about the pivot shaft 47 as shown in Figs. The outer frame 42 is provided with a seat support 77 (including the driver's seat 71), a movable portion 78a which is a lower portion of the rear portion plate 78, The movable portion 33b (including the ventilation net 34) is connected, and these members can be oscillated together with the dustproof cover 41. [ Therefore, when the dust cover 41 is swung open, not only the right side surfaces of the engine room 21 and the condenser room 31 are opened, but also the upper and the front surfaces of the engine room 21 and the lower surface of the condenser room 31 A part of the front surface and a part of the front surface are also opened to facilitate the maintenance work of the engine room 21 and the condenser room 31. [

In order to prevent the movable portion 33b of the partition plate 33 from interfering with the bottom surface 36c of the lower stay 36, the right portion of the lower stay 36 on the side of the dust cover 41 The right side portion 36b of the lower stay 36 is moved away from the partition plate 33 so that the bottom surface 36c of the lower stay 36b intersects the swing locus T of the movable portion 33b of the partition plate slightly upward And is spaced upward. That is, the right portion 36b of the lower stay 36 is positioned above the left portion 36a on the opposite side of the dust cover 41 from the lower stay 36. Specifically, the bottom surface 36c of the right portion 36b of the lower stay 36 is folded upward to the right side. The lower stay 36 is bolted to the upper surface of the door frame 1a with only the left portion 36a of the lower stay 36 together with the fixed portion 33a of the partition plate 33 which does not swing.

4, a packing 25 is provided on the outer peripheral portion of the outer side surface of the radiator 23 in the lateral direction of the base body. When the dust cover 41 is closed, an intermediate plate (not shown) provided in close contact with the inner side surface of the outer frame 42 in the gas transverse direction and the packing 25 and also over the front portion and the rear portion of the outer frame 42 44 and the packing 25 are in close contact with each other and a shroud for guiding the outside air from the vibration damping net 43 to the radiator 23 is formed.

[About placement of receiver]

The receiver 95 is arranged at a position that does not impede the opening and closing fluctuations of the grain tank 5 in the space between the condenser room 31 and the grain tank 5 as shown in Figs. . The receiver 95 is provided at the right end of the back surface of the condenser 92 through a support bracket 96 extending toward the rear of the base. Therefore, only by opening the grain tank 5, the receiver 95 can be exposed at a position near the outer surface of the base body.
