The bottom end of the extrusion frame 81 may be provided with a pulley and the like so that the extrusion frame 81 can move on the ground. Meanwhile, the bottom of the extrusion frame 81 can also be provided with a limiting structure, and the limiting structure can limit the extrusion frame 81 to move on the ground, so that the extrusion frame 81 is stably placed at a position required to be fixed. Certainly, the surface of the extrusion frame 81 can be coated with oil-resistant and corrosion-resistant coating, so that the kitchen swill can be prevented from corroding the square pipe. The square tube can be made of hard materials such as stainless steel or carbon steel, and the number of the square tubes is determined according to the overall structure of the extrusion frame 81, so that the overall firmness can be guaranteed as much as possible.
The crush can 82 is mounted to the crush can 81, and in some embodiments, the crush can 82 can be integrally formed with the crush can 81. Wherein, set up extrusion chamber 83 and water storage space 84 in the extrusion shell 82, extrusion chamber 83 and water storage space 84 coaxial setting. The water storage space 84 is located outside the squeezing chamber 83 and communicates with the squeezing chamber 83 through a plurality of squeezing through-holes 85 opened in the squeezing housing 82. The water storage space 84 may be shaped in a ring shape in practice, which surrounds the squeezing chamber 83 so that liquid squeezed out of the squeezing chamber 83 can be stored in the water storage space. At least two sliding grooves 86 parallel to the axial direction of the extrusion cavity 83 are formed on the inner wall of the extrusion shell 82 close to the extrusion cavity 83, and one end of the extrusion shell 82 is an open end.
The feed inlet of the feeding mechanism is inserted into the other end of the extrusion shell 82 and is used for conveying kitchen swill into the extrusion cavity 83. In this embodiment, the feeding mechanism includes a feed hopper 101. The feeder hopper 101 is secured to the squeeze frame 81 and squeeze shell 82 with the mouth of the hopper located in the squeeze chamber 83. In other embodiments, the feeding mechanism may convey the kitchen waste into the extruding cavity 83 by other structures, such as a tubular structure like a feeding pipe, and also convey the kitchen waste into the extruding shell 82 by a groove-shaped structure.
The extruding device comprises an extruding motor 87, a stud 88, an extruding block 89, a stirring fan blade 90 and a positioning column 105. An extrusion motor 87 is mounted on the extrusion frame 81, and an output shaft is connected to one end of a stud 88. A stud 88 is positioned in the extrusion chamber 83, the central axis of which may coincide with the central axis of the extrusion chamber 83. The extrusion block 89 is screwed on the stud 88, and the outer wall of the extrusion block is attached to the wall of the extrusion cavity 83. The pressing block 89 is provided with at least two sliding blocks 91, the number of the sliding blocks 91 is at least two, the at least two sliding blocks 91 respectively correspond to the at least two sliding grooves 86, and each sliding block 91 can slide in the corresponding sliding groove 86. Therefore, when the stud 88 rotates, the sliding block 91 can only slide in the sliding groove 86, so that the extruding block 89 integrally moves along the axial direction of the stud 88, and the extruding function of the kitchen swill in the extruding cavity 83 is realized. The number of the stirring blades 90 is at least one group, and each group of the stirring blades 90 is inserted around the other end of the stud 88. Two ends of the positioning column 105 are respectively fixed on the inner wall of the extrusion shell 82, and the other end of the stud 88 is rotatably installed in the positioning column 105, so that the stud 88 is more stable in rotation. The stirring fan blades 90 can stir the kitchen swill when the stud 88 rotates, so that the kitchen swill can be more uniformly distributed in the extrusion cavity 83. Meanwhile, the resistance of the stirring fan blades 90 in the extrusion process is certainly increased, so that the depth of the stirring fan blades 90 in the extrusion cavity 83 needs to be fully considered when the stirring fan blades 90 are installed, the number and the blade surface of the stirring fan blades 90 can be reduced, and the stirring can be smoothly carried out.
In the present embodiment, the stud 88 includes a connecting section 98, a threaded section 99, and a stop section 100.

The threaded sleeve 80 is in threaded connection with the threaded section 99 and is limited above the limiting section 100. Thus, when the stud 88 rotates, when the resistance of the kitchen swill to the stirring fan blade 90 is relatively small, the stirring fan blade 90 still rotates along with the rotation of the stud 88, and when the resistance is relatively large, the threaded section 99 and the threaded sleeve 80 rotate relatively, and the stirring fan blade 90 stops rotating and moves along with the axial movement of the threaded sleeve 80 along the threaded section 99 to move to a place with relatively small resistance.
