Existing drying machines include rotary dryers, fluidized bed dryers, and belt dryers. However, in actual use, when using rotary dryers for deep drying of fertilizers, the fertilizer inside the dryer is prone to heat-induced clumping. Current solutions typically involve adding vibration devices, but these devices can increase noise and, due to prolonged vibration, can reduce the equipment's lifespan. Utility Model Content

[0010] To facilitate the crushing of fertilizers by the crushing plate:

[0011] As a further improvement to the above technical solution: the crushing plate and the diversion pipe are arranged with their axes coincident.

[0012] The beneficial effects of this improvement are as follows: the overlapping axis setting can facilitate the crushing plate to crush the clumped fertilizer, ensuring the efficiency and effect of fertilizer drying. Furthermore, the crushing plate can ensure the dispersion of fertilizer, thereby ensuring the efficiency and effect of fertilizer drying.

[0015] The beneficial effects of this improvement are: the coincident axis setting allows the rotary joint to rotate along the main exhaust pipe, ensuring the position of the branch exhaust pipe.

[0016] For easier exhaust:

[0017] As a further improvement to the above technical solution: two branch exhaust pipes are symmetrically arranged about the axis of the rotary joint.

[0018] The beneficial effect of this improvement is that the axially symmetrically arranged branch exhaust pipes can work with the filter plate to discharge the gas.

[0019] To facilitate the installation of exhaust pipes:

[0020] As a further improvement to the above technical solution: the exhaust pipe and the diversion pipe are connected by threads.

[0021] The beneficial effect of this improvement is that the threaded connection can ensure the airtightness of the connection between the exhaust pipe and the diversion pipe.

[0022] To facilitate the fixing of the branch exhaust pipe:

[0023] As a further improvement to the above technical solution: the branch exhaust pipe is fixed to the insulation shell by a snap fastener.

[0024] The beneficial effect of this improvement is that the connection between the branch exhaust pipe and the insulation shell can be made more reliable and secure through the snap-fit ​​mechanism. Attached Figure Description
