[0023] As the preferred technical solution of this embodiment, Figure 2 and Figure 3 As shown, a fixing rod 9 is provided on one side of the lower end of the extrusion roller 7, and a cleaning layer 8 is fixedly connected to the surface of the fixing rod 9 around, and plug plates 12 are fixedly connected on both sides of the fixing rod 9, and a fixing block 10 is clamped at one end of the plug plate 12, and a fixing groove 11 is provided on one side of the fixing block 10, and the plug plate 12 is inserted in the fixing groove 11, and plug grooves 17 are provided at the upper and lower ends of the plug plate 12, and the fixing block 10 is fixedly connected to the inner wall of the feed pelletizing box 2, and the plug plates 12 on both sides of the fixing rod 9 are inserted into the fixing groove 11 on one side of the fixing block 10, so that the two fixing blocks 10 as a whole fix the fixing rod 9.

[0024] As the preferred technical solution of this embodiment, Figure 4 and Figure 5 As shown, an inner cavity 14 is provided at both the upper and lower ends of one side of the fixed block 10, and a plug-in column 13 is movably provided in the inner cavity 14. A movable plate 16 is fixedly connected to the four sides of the plug-in column 13, and one end of the movable plate 16 is connected to a spring 15. One end of the spring 15 is fixedly connected to the end wall of the inner cavity 14. The plug-in column 13 is located in the middle of the spring 15, and one end of the plug-in column 13 is plugged into the plug-in slot 17.

[0025] Working principle: Turn on the motor 4 so that the output shaft at one end of the motor 4 drives the rotating shaft in the reverse rotating gear box 3, and the rotating shaft of the reverse rotating gear box 3 drives the two long shafts 6 to rotate. Under the action of the reverse rotating gear box 3, the two long shafts 6 rotate in opposite directions, so that the long shaft 6 drives the two extrusion rollers 7 to rotate in relative opposite directions. Then the upper discharge pipe 1 transports the material downward, and the material in the discharge pipe 1 enters the feed pelletizing box 2 through the discharge port at the upper end of the feed pelletizing box 2. Under the relative extrusion movement of the two extrusion rollers 7, the material is gradually squeezed and crushed, and finally enters the lower part of the feed pelletizing box 2.

[0026] By arranging a cleaning layer 8 on one side of the extrusion roller 7, when the extrusion roller 7 rolls, the surface of the cleaning layer 8 contacts the extrusion roller 7, and the cleaning layer 8 is made of a soft material such as sponge. Then, when the surface of the extrusion roller 7 contacts the cleaning layer 8, the cleaning layer 8 gradually scrapes the materials in the gaps on the surface of the extrusion roller 7, so that the surface of the extrusion roller 7 is kept clean, thereby preventing the extrusion roller 7 from being contaminated with too many feed particles, resulting in poor crushing effect.

[0027] By fixing the fixed blocks 10 on both sides of the inner wall of the feed pelletizing box 2, a fixed groove 11 is provided at one end of the fixed block 10, wherein the plug plates 12 on both sides of the fixed rod 9 are inserted in the fixed groove 11, and this arrangement enables the overall fixed rod 9 and the cleaning layer 8 to be inserted between the two fixed blocks 10, and an inner cavity 14 is provided inside the upper and lower ends of the fixed block 10, wherein the spring 15 inside the inner cavity 14 extends the elastic force to push the movable plate 16 in the direction of the plug plate 12, thereby enabling the movable plate 16 to drive the plug-in column 13 to press downward, and one end of the plug-in column 13 is inserted in the plug-in groove 17 on the plug plate 12, then this arrangement and operation enables the plug plate 12 to be fixed in the fixed groove 11, and further enables the fixed rod 9 to be fixed between the two fixed blocks 10;

[0028] If the overall fixing rod 9 and cleaning layer 8 are to be replaced, the plug-in columns 13 on the upper and lower sides are pulled outward, and the plug-in columns 13 move vertically outward, so that the plug-in columns 13 drive the movable plate 16 to press the extension elastic force of the spring 15, and one end of the plug-in column 13 is disengaged from the plug-in slot 17 on the plug-in plate 12, which ends the clamping of the two plug-in columns 13 on the plug-in plate 12, so that the plug-in plate 12 can be disengaged from the fixing slot 11 in the fixing block 10. The above arrangement realizes the replacement of the overall fixing rod 9 and the cleaning layer 8, keeps the surface of the cleaning layer 8 clean, and avoids the cleaning layer 8 surface being contaminated and causing its own cleaning function to decrease.
