The cleaner 32 is connected, and the intake port (inlet) of the DPF unit 40 which removes impurities in exhaust gas is connected to the exhaust manifold 30B via the connection pipe 50.

(DPF unit)

The DPF unit 40 has an oxidation catalyst (DOC) 40A on the inlet port (inlet) side and a particle filter (DPF) 40B on the exhaust port (outlet) side, and is discharged from the engine 9. The unburned fuel in the exhaust gas is oxidized by the DOC 40A, and the granulated material in the exhaust gas is removed by the filtration action of the DPF 40B.

As shown in FIG. 2 etc., the DPF unit 40 is fixed to the base frame 2 without the mounting rubber 9a in order to simplify mounting structure. The DPF unit 40 is preferably arranged near the engine 9 in order to prevent the temperature of the exhaust gas discharged from the engine 9 from dropping, so that the rear surface of the engine 9 and the first grain apparatus 14 Placed between bases. In addition, the front end of the DPF unit 40 is disposed at approximately the same position as the front wall of the grain tank 6, so as to promote drying of the grains stored in the grain tank 6.

As shown in FIGS. 3 and 4, the DPF unit 40 is approximately centered in the left and right directions of the grain tank 6 so as to dry the grains stored in the grain tank 6 by heat dissipation from the DPF unit 40. It is arrange | positioned under the part, and is arrange | positioned under the silhouette of the bottom inclination wall 23B of the grain tank 6 in planar view. The exhaust port of the DPF unit 40 is also located below the inclined wall 23B.

As shown in FIG. 2, the intake port of the DPF unit 40 is connected to the exhaust manifold 30B through the connecting pipe 50, and the exhaust port of the DPF unit 40 is provided with exhaust gas from which impurities and the like have been removed. The exhaust pipe 60 to discharge is connected.

The connection pipe 50 is a first connection pipe 51 made of steel pipe, a flexible tube 52 made of a stainless pipe having flexibility to reduce propagation of vibration of the engine 9, and a second connection pipe made of steel pipe. It consists of 53. The entirety of the connection tube 50 or the flexible tube 52 may be formed of a material having flexibility such as rubber.

Even when the engine 9 and the DPF unit 40 generate different vibrations when the engine 9 is started or when the gas is driven, the connection portion between the intake port of the DPF unit 40 and the connection pipe 50 or the connection pipe ( The stress applied to the connecting portion 50 and the like of the exhaust manifold 30B is reduced, so that metal fatigue of the exhaust inlet pipe is less likely to occur, thereby improving durability.

As shown in FIG. 2, when viewed from the side, the first connecting pipe 51 extends substantially downward from the exhaust manifold 30B, and the flexible tube 52 extends from the tip end of the first connecting pipe 51. It extends substantially downward, and the 2nd connection pipe 53 is bent about 90 degrees from the front end of the flexible tube 52, and is extended backward and is connected to the inlet port of the DPF unit 40.

The exhaust pipe 60 is comprised by the exhaust pipe (tape pipe) 61 which consists of steel pipes, and the cover 62 formed in the curved shape or the refractive shape which prevents intrusion of rainwater etc. into the exhaust pipe 61. As shown in FIG.

The base of the exhaust pipe 61 (lower portion of the exhaust pipe 61) is high in the inclined wall 23B having a step after extending upward from the exhaust port (outlet) of the DPF unit 40 from the side. It is inclined and extended toward the left front upward along the lower surface of the inclined wall 23B of the side. The upper part of the exhaust pipe 61 extends steeply upward from the front end of the base of the exhaust pipe 61, and the cover 62 faces the opening 62A toward the rear of the exhaust port formed at the upper end of the exhaust pipe 61. I wear it. The cover 62 is configured to be attached to the upper end of the exhaust pipe 61 via a stay, but may be configured to be attached to the upper end of the first grain-type device 14. The cover 62 is formed in a semicircular arc shape with a longitudinal cross section. The base (lower portion) of the cover 62 is formed in a cylindrical shape, and the inner diameter of the cylindrical portion is formed larger than the outer diameter of the upper end of the exhaust pipe 61. . The cover 62 is attached to the upper end of the exhaust pipe 61 so that a predetermined gap is formed between the inner circumferential surface of the lower cover outer body of the cover 62 and the outer circumferential surface of the upper end of the exhaust pipe 61. In this gap, a diffuser effect is generated by the flow of the exhaust gas discharged from the upper end of the exhaust pipe 61 to the cover 62 side, and the temperature of the exhaust gas discharged from the opening 62A is further reduced by the intake of outside air.

It is arrange | positioned in parallel to the front side of.

The inner diameter of the base of the exhaust pipe 61 may be formed to a large diameter based on the outer diameter of the exhaust port of the DPF unit 40. As a result, a diffuser effect is obtained, and air is drawn in from the gap between the base of the DPF unit 40 and the exhaust pipe 61 by the outflow of the exhaust gas discharged from the DPF unit 40 to the exhaust pipe 61, thereby exhausting the exhaust pipe 61. The temperature of the exhaust gas in the ()) can be lowered, and rainwater and the like that have invaded from the opening 62A of the cover 62 can be drained out of the device from the gap. In addition, the high temperature atmosphere around the DPF unit 40 can be sucked out of the device to prevent failure of sensors installed in the vicinity of the DPF unit 40.

The air cleaner 33 is arrange | positioned behind this transparent plate 84, and when this transparent plate 84 is opened to the left side, maintenance of the air cleaner 33 can be performed from a side window.

As shown in FIG. 9, the upper part of the air cleaner 33 and the lower part of the precleaner 32 are previously integrated by connecting with the connection pipe 34, and this integrated air cleaner 33 and the precleaner 32 are integrated. Can be mounted on the body side via the support member 80 and the support member 83.

As shown in FIG. 9, the rear window of the cabin 7 forms a rear window, and the transparent plate (second transparent plate) 86 which blocks this rear window is centered on the upper point (second point) R. As shown in FIG. It is installed to be able to open rearward. The precleaner 32 is disposed at a position biased to the left than the transparent plate 86 in order to prevent the opening and closing of the transparent plate 86. When the transparent plate 86 is opened backward, the precleaner 32 can be maintained from the rear window of the cabin 7.

The air cleaner 33 and the intake manifold of the engine 9 are connected by the connection pipe 35.

As shown in FIG. 11, the cover 62 arrange | positioned at the upper end part of the precleaner 32 and the exhaust pipe 61 is arrange | positioned in substantially the same height, and is arrange | positioned in substantially the same position also in the left-right direction, but of the cover 62 The opening 62A is opened toward the side opposite to the side where the precleaner 32 is present. As a result, the exhaust gas guided by the cover 62 is less likely to be sucked into the precleaner 32.

In the embodiment shown in FIG. 11, FIG. 12, the recessed part which formed the 1st grain grain apparatus 14, the 2nd grain grain apparatus 15, and the exhaust pipe 61 in the vertical wall 23A of the left wall of the grain tank 6 is shown. It is arrange | positioned in 22A.

As shown in FIG. 11, FIG. 13, and FIG. 14, the DPF unit 40 covers the lower surface with the cover 88 which opened, and the pressure sensor 89 which detects the internal pressure of DPF on the upper side of this cover 88 is shown. Sensors, such as these, are attached.
