[0026] During operation, the output end of the motor 11 is connected to the gear 7, and adjacent gears 7 are driven to be connected, so that the two casings 12 rotate inwards at the same time, which is convenient for extrusion molding of the raw materials.

[0033] Working principle: During the fertilizer production and processing, when the raw materials need to be extruded, the raw materials are put into the feeding trough 3, and the raw materials fall into the surface of the casing 12 from the bottom opening of the feeding trough 3. At this time, the motor 11 is started by an external power supply, and the motor 11 drives the connecting rod 8 and the turntable 9 to rotate through the gear 7. The support assembly 10 supports the turntable 9, and the connecting rod 8 drives the casing 12 to rotate.

At the same time, the heater 4 is started by an external power supply, and the internal circuit of the heater 4 is connected to the heating tube 6 through the support arm 5, so that the heating tube 6 generates heat, and the heat is accelerated to be transferred to the casing 12 through the heat conduction hole 61, so that the moisture of the processed raw materials is accelerated to evaporate, which is convenient for the raw materials to separate from the surface of the casing 12. The air pump 19 is started by an external power supply, and the air pump 19 compresses the air and transports the air to the inside of the connecting tube 18 through the connecting tube 18, and then sprayed out by the air nozzle 17. Because the air nozzle 17 is inclined to the surface of the casing 12, it is convenient to accelerate the raw materials to separate from the surface of the casing 12, and the raw materials are collected through the collecting trough 15;

[0034] When the device needs to maintain the shell 12 or replace the shell 12 with a different size groove 13 after long-term operation, the slider 102 is lowered by removing the clamping column 104 inside the perforation 103, and the shell 12 is slid out. The replaced shell 12 aligns the internal groove 13 with the surface of the connecting rod 8, and the slider 102 is slid up to fix the support frame 101 and the slider 102 through the clamping column 104.
