Since the front frame 103 is not provided with a leg portion at the lower left of the cover portion 103A, the front frame 103 can be prevented from interfering with a power mechanism such as an electric belt from the engine 9. have.

The front side frame 103 may have a structure having two leg portions similarly to the rear side frame 104.

(Upper connection frame and lower connection frame)

The front frame 103 and the rear frame 104 are connected by an upper connecting frame 105 and a lower connecting frame 106 in the front-rear direction. The fixing portion 105A of the front end portion of the upper connecting frame 105 is fixed to the engine rear frame 109 standing from the base 41 at the rear portion of the engine 9.

(cover)

The cover 107 is attached to the front side frame 103 and the rear side frame 104, the upper connecting frame 105, and the lower connecting frame 106. Specifically, the cover 107 is composed of a left cover 107L and a right cover 107R, and one left cover 107L is fixed at its upper end to the upper connecting frame 105, and the threshing apparatus 5 is formed from this upper end. The upper inclined surface inclined so that the side is lowered, and the side portion and the grain tank 6 side which are substantially vertically downward from the lower end of the upper inclined surface are inclined low, and the rear frame 104 and It has a lower inclined plane up to the crossing position.

The upper right side cover 107R is fixed to the upper connecting frame 105 with an upper end fixed to the upper side of the grain tank 6 side from the upper connecting frame 105 and horizontally from the right end of the upper side. The upper inclined surface inclined so that the grain tank 6 side is lowered, and a side portion which faces downwardly substantially vertically from the lower end of the upper inclined surface, and the lower end of this side portion is fixed to the lower connecting frame 106.

The front and rear ends of the left cover 107L and the right cover 107R are respectively joined by fastening members such as bolts so that no gap is formed between the front frame 103 and the rear frame 104.

However, the cover 107 covers the upper and left and right sides of the DPF unit 40, and the lower side (the portion between the left cover 107L and the lower end of the right cover 107R, the lower opening Hb) is open. Formed.

The front side and the rear side of the DPF unit 40 are covered with the cover portions 103A and 104A of the front side frame 103 and the rear side frame 104 as described above, The cover portion 104A is provided only on the right side of the left end portion of the upper connecting frame 105, and is opened between the cover portion 104A and the left cover 107L (rear opening opening Hr).

As described above, the engine 9 is attached to the base 41 through the elastic engine mount 9B, and the DPF unit 40 is directly attached to the base. The engine 9 vibrates greatly with respect to the base 41 at the time of starting or when a load such as the threshing apparatus 5 is generated, but in this case, the pipe or the DPF unit is changed from the difference in natural frequencies of the engine 9 and the DPF unit 40. There is a risk of damaging the 40. Since the engine 9 and the DPF unit 40 are connected via the flexible flexible tube 52, even if the vibration state of the engine 9 and the DPF unit 40 was different, the difference of this vibration is connected. DPF absorbed by the bending of the pipe | tube 52, the damage of the 1st connection pipe 51 and the 2nd connection pipe 53, the damage of the DPF unit 40, and the DPF by the vibration of the DPF unit 40. The fall of collection efficiency of the particulate matter of 40B can be prevented.

The concave portion 22 is faced. That is, part or all of the DPF unit 40 enters below the left wall 21D of the grain tank 6.

Since the DPF unit 40 is arrange | positioned so that the center position of the longitudinal length of the front-back direction may be substantially corresponded with the ground center C of the ground length L of the front-back direction of the traveling apparatus 3, it travels the uneven pavement. Therefore, the influence of the up and down vibration caused by the posture change of the body of the combine 1 in the front-back direction can be reduced, and the fall of the collection efficiency of granulated material and the damage by vibration can be prevented.

In addition, the combine 1 by this invention is a structure which changes the inclination attitude of front and back by the single pitching cylinder 57, but is equipped with two pitching cylinders before and behind, and changes the inclination attitude of front and rear. When employ | adopting, it is preferable to arrange | position so that the center position of the length of the front-back direction of the DPF unit 40 may become the center of the front-back space of two pitching cylinders.
