The first fixing member 14211 and the second fixing member 14241 are aligned with the discharge port 200 of the driving device 20 and the bottom end of the discharge body 141, respectively, and are fixedly installed. The mounting of the connecting bracket 142 has no high requirement on accuracy. The size and shape of the first discharging pipe 1421, the second discharging pipe 1422, the base 1423, and the third discharging pipe 1424 may be determined according to the specific situation of the agricultural machinery, and the applicability of the connecting bracket 142 is strong.

When the connection bracket 142 is provided with the soft discharge pipe 1425, since the connection bracket 142 is stably connected to the vehicle frame 12, the shaking range of the connection bracket 142 itself is small, and most of the shaking is transmitted to the connection bracket 142 such that both ends of the soft discharge pipe 1425 are pressed, the soft discharge pipe 1425 is bent and deformed to reduce a certain degree of shaking, so that the shaking transmitted to the discharge body 141 is reduced to protect the discharge body 141. That is, the attachment bracket 142 itself is stably installed, so that the vibration transmitted to the attachment bracket 142 is used for the bending deformation of the soft discharge pipe 1425, contributing to more reduction of the vibration, reducing the influence on the discharge body 141.

In another example of the present invention, as shown in fig. 6, the soft exhaust pipe 1425 may be further disposed on the first exhaust pipe 1421, and a part or the whole of the first exhaust pipe 1421 is disposed as the soft exhaust pipe 1425, so that the part or the whole of the first exhaust pipe 1421 may endure a certain degree of bending deformation. The vibration generated by the driving device 20 is directly transmitted to the first discharging pipe 1421 or the soft discharging pipe 1425, and the soft discharging pipe 1425 is bent and deformed when vibrating, so as to reduce a certain degree of vibration. The vibration is reduced through the soft discharge pipe 1425 and then is transmitted to the second discharge pipe 1422, the base 1423, and the third discharge pipe 1424, and finally to the discharge body 141. Since the vibration transmitted from the driving device 20 is reduced through the soft discharge pipe 1425 and then is transmitted to the discharging body 141, the vibration generated in the discharging body 141 is reduced to some extent, thereby reducing the influence of the vibration on the discharging body 141 and protecting the discharging body 141.

In another example of the present invention, as shown in fig. 7, the soft discharge pipe 1425 may be disposed between the first discharge pipe 1421 and the second discharge pipe 1422, the first discharge pipe 1421 and the second discharge pipe 1422 are connected through the soft discharge pipe 1425, and the vibration of the first discharge pipe 1421 is transmitted to the soft discharge pipe 1425, and after being completely deformed by the soft discharge pipe 1425 and reduced to some extent, is continuously transmitted to the base 1423 and the third discharge pipe 1424, and finally transmitted to the discharge body 141.

In another example of the present invention, the soft exhaust pipe 1425 may be further disposed on the third exhaust pipe 1424.

The number and the position of the soft discharge pipes 1425 provided at the connection bracket 142 may be designed according to the actual situation. By providing the soft discharge pipe 1425 so that the vibration transmitted from the driving device 20 to the discharge body 141 is reduced, the discharge body 141 is protected.
