Preferably, the upper half part of the heating block is provided with a round hole, and the aperture is gradually increased from the right side to the left side.

Preferably, the lower half part of the heating block is provided with spirally arranged hole grooves, and the width of the hole grooves is gradually reduced from the right side to the left side.

Preferably, the breaker shape is the arc, breaker's inside is arranged there is the helical blade, the sharp-pointed blade of top fixedly connected with of helical blade, the sharp-pointed blade's sharp-edged blade is perpendicular with wind direction and gravity.

The invention has the following beneficial effects:

1. according to the invention, strong wind generated by the fan is blown to the screen body through the heating block, so that the organic fertilizer is dried, the powdery organic fertilizer is blown to the powdery material outlet, the granular organic fertilizer is blown to the granular material outlet, and the massive organic fertilizer falls naturally, thereby solving the problems that the granular organic fertilizer is crushed in the vibrating screen due to vibration excitation and the wet organic fertilizer is operated for a period of time to block the screen holes.

2. According to the invention, the circular holes with the diameters gradually increasing from right to left are formed in the upper half part of the heating block, and the hole grooves which are gradually reduced from right to left and are spirally arranged are formed in the lower half part of the heating block, so that the organic fertilizer can be screened to respective discharge holes by heating the strong wind through the circular holes and reducing the wind speed to normal wind speed, the strong wind can accelerate the cutting property and heat airflow again through the hole grooves, and the problems that the granular organic fertilizer is crushed in the vibrating screen due to vibration excitation and the screen holes are blocked when the wet organic fertilizer operates for a period of time are solved.

3. According to the invention, the spiral blade is driven by strong wind to form rotary cutting and is matched with the sharp blade, so that the blocky organic fertilizer is cut by accelerated strong wind to be collided with the sharp blade to be crushed, and then is crushed into particles by the spiral cutting of the spiral blade, and the problem that the blocky organic fertilizer needs to be re-processed in the previous manufacturing step to increase labor is solved.
