[0019] The advantages of this invention are:

[0020] 1. The crushing component outputs power and drives the feed drive pulley to rotate via the drive belt. The feed drive pulley then drives the central rotating column to rotate, which in turn drives the feed screw to rotate. The food waste is placed in the collection pipe and, under the spiral action of the feed screw, enters the crushing component.

[0021] 2. Start the actuator motor, which in turn drives the drive shaft and drive bevel gear four to rotate. Drive bevel gear four then drives drive bevel gear two and three to rotate, and simultaneously drives drive bevel gear one to rotate. This, in turn, drives the drive belt through the drive spur shaft and the crushing drive pulley, providing power output. Simultaneously, the rotation of drive bevel gear two drives the middle rotating shaft, which in turn drives the middle crushing blades to rotate. The rotation of drive bevel gear three drives the secondary crushing tray to rotate, which in turn drives the secondary crushing discharge blades to rotate. Through the contact between the middle crushing blades and the kitchen waste, the initial crushing of the kitchen waste is achieved. The food waste, initially pulverized, comes into contact with the secondary pulverizing blades through discharge openings one and two, thus undergoing secondary pulverization. The pulverized food waste then enters the discharge box through the outer discharge port and connecting pipe, and is collected through the discharge outlet. Simultaneously, the relative rotation adjustment rotor drives the transmission spur gear to rotate, which in turn drives the middle pulverizing blades to rotate. This changes the effective contact area between the middle pulverizing blades and the food waste, thereby altering the size of the pulverized food waste pieces and adjusting the initial pulverization effect.

[0022] 3. By driving the connecting rod to move the middle sliding sleeve, the middle sliding sleeve and the middle connecting sleeve rotate relative to each other, which in turn changes the area of ​​the material opening one and the discharge opening two, and thus changes the amount of kitchen waste passing through the area of ​​the material opening one and the discharge opening two.

A transmission spur gear 3-22 is fixedly mounted on the middle-end crushing blade 3-7. The transmission spur gear 3-22 meshes with the adjusting rotor 3-8.

With this configuration, starting the actuator motor 3-16 drives the transmission shaft 3-15 and the fourth transmission bevel gear 3-14 to rotate. The fourth transmission bevel gear 3-14 then simultaneously drives the second transmission bevel gear 3-12 and the third transmission bevel gear 3-13 to rotate, and also drives the first transmission bevel gear 3-11 to rotate. This, in turn, drives the transmission belt 4 via the transmission spur shaft 3-10 and the crushing transmission pulley 3-9, providing power output.

Simultaneously, the relative rotation of the adjusting rotor 3-8 drives the transmission spur gear 3-22 to rotate, which in turn drives the middle crushing blades 3-7 to rotate. This changes the effective contact area between the middle crushing blades 3-7 and the kitchen waste, thus changing the size of the initially crushed pieces and adjusting the initial crushing effect.

[0057] Among them, multiple external discharge holes 3-2 are arranged in a circumferential array along the central axis of the crushing box 3-1.

[0058] Among them, multiple secondary crushing discharge blades 3-5 are arranged in a circumferential array along the central axis of the secondary crushing tray 3-4.

With this configuration, the middle sliding sleeve 3-3-4 is driven to move by the driving connecting rod 3-3-5, so that the middle sliding sleeve 3-3-4 and the middle connecting sleeve 3-3-1 rotate relative to each other. This causes the area of ​​the material opening 1 3-3-2 and the discharge opening 2 3-3-3 to change, which in turn changes the amount of kitchen waste passing through the area of ​​the material opening 1 3-3-2 and the discharge opening 2 3-3-3.

[0063] Among them, multiple discharge openings 3-3-2 are arranged in a circumferential array along the central axis of the middle connecting sleeve 3-3-1.
