The combine in the above document has a condenser placed outside the engine room, which is likely to become relatively hot due to heat from the engine, so that the condenser can be cooled efficiently, while supporting to contain and support the condenser. Since the case is provided and a cooling fan that exhausts air sucked from the threshing portion side to the glen tank side is installed on the right side surface of the support case, the swarf on the threshing portion side is sucked to the capacitor side, In some cases, such as clogging may cause problems such as a decrease in cooling efficiency.
The present invention is a combine in which a condenser and a cooling fan for the condenser are arranged on the outside of the engine room, and prevents swarf on the threshing part side from being sucked into the condenser side, thereby reducing cooling efficiency, etc. It is an object to provide a combine that prevents defects.

  In order to solve the above problems, first, the Glen tank 4 is disposed behind the control unit 6, the threshing unit 3 is provided on the left side of the Glen tank 4, and extends from the Glen tank 4 side to the threshing unit 3 side during storage. The exhaust auger 16 extending obliquely left frontward in plan view is a combine in which the condenser 38 for the air conditioner 23 and the cooling fan 41 for the condenser 38 are disposed outside the engine room 22 and accommodates and supports the condenser 38. The support case 39 is disposed between the discharge auger 16 and the grain tank 4 when stored in a plan view, and the air sucked from the grain tank 4 side is exhausted to the threshing part 3 side. The cooling fan 41 is arranged on the left side surface of the capacitor 38 inside 39.

  Secondly, the support case 39 is supported through the frame part 46 on the steering part 6 side and the frame part 44 on the threshing part 3 side.

  Third, the right side wall of the support case 39 is configured by a detachable cover body 43, and the glen tank 4 is supported so as to be horizontally rotatable so that at least a part of the right side of the threshing portion 3 is exposed. It is characterized by that.

  According to the above-described combine, the air sucked from the grain tank side is exhausted to the threshing portion side by the cooling fan, so that swarf on the threshing portion side is prevented from being sucked into the condenser side. Therefore, it is possible to minimize problems caused by sucking dust and so on to the condenser side, and by eliminating the condenser from the engine room, other cooling objects such as radiators and oil coolers can be made more efficient. It becomes possible to cool down.

  Further, if the support case is supported via the frame part on the steering part side and the frame part on the threshing part side, the number of members supporting the support case can be reduced, and the manufacturing cost is reduced. In addition, since the above-described frame portion having high rigidity is used, high strength can be ensured when supporting the support case.

  Further, if the right side wall of the support case is constituted by a detachable cover body and the glen tank is supported so as to be horizontally rotatable so that at least a part of the right side of the threshing portion is exposed, the glen tank is exposed.

  1 to 3 are a left side view, a right side view and a plan view of a self-removable combine to which the present invention is applied. The combine shown in the figure has a threshing device (threshing unit) 3 installed on the left side (hereinafter simply “left”) in the traveling direction on the body frame 2 supported by a pair of left and right crawler type traveling devices 1L and 1R. A grain tank 4 is provided on the right side (hereinafter, simply “right”) side of the threshing device 3 on the body frame 2, and the control unit is located in front of the grain tank 4 on the body frame 2 and diagonally forward to the right of the threshing device 3. 6 (see FIGS. 7 and 8) and a cabin 7 that covers the control unit 6 constitute a traveling machine body 8, and a pre-processing unit is connected to the front part of the traveling machine body 8 via a vertical cylinder 9 or the like. 11 is connected so that raising and lowering is possible.

  During the travel to the forward side, which is the traveling direction of this combine, the pre-processing unit 11 is driven to cut and harvest the grain culm in the field. The cereals conveyed rearward by the pretreatment unit 11 are received by the feed chain 12 in the front-rear direction arranged on the left side of the threshing device 3. The threshing cake received by the threshing feed chain 12 is threshed by the threshing device 3 in the process of being conveyed rearward and becomes waste. While the waste is transported rearward by the waste transporting body 13 and is cut as it is or after being processed by the post-processing unit 14 at the rear end of the traveling machine body 8, it is discharged from the rear end of the traveling machine body 8 to the outside of the machine. The processed product that has been threshed by the threshing device 3 is wind-selected into swarf and the like and cereal grains, and the swarf is discharged from the rear end of the traveling machine body 8 and the grain It is conveyed and stored in the tank 4.

  The grain in the Glen tank 4 is discharged out of the machine by the discharge auger 16. The discharge auger 16 includes an up-down vertical cylinder 17 that is erected on the right side of the rear end of the traveling machine body 8, and a discharge cylinder 18 that has a base end supported on the upper end of the vertical cylinder 17.

The capacitor unit 29 is a high-pressure refrigerant. Is configured to liquefy. The refrigerant from the condenser unit 29 is sent to the receiver 28 through the refrigerant pipe 36. The receiver 28 separates the refrigerant, moisture, and impurities that could not be liquefied from the refrigerant. In this way, the refrigerant completely liquefied by the receiver 28 is sent again to the air conditioner unit 26 through the refrigerant pipe 37. Thereafter, the inside of the cabin 7 is cooled by the circulation of the refrigerant, which continues from the air conditioner unit 26 → the compressor 27 → the condenser unit 29 → the receiver 28 → the air conditioner unit 26 →.
