The crushing blade 3-4 is made of 65Mn spring steel, or 9crsi, SK5, T10 and other types of materials, and its heat treatment hardness is HRC52-55 degrees. The output power of the crushing motor drives the crushing roller through the crushing transmission device to drive the crushing blade thereon to cut and crush the kitchen waste; the gap between the blades on adjacent crushing rollers is The output speed difference of adjacent crushing motors 3-1 can be set and adjusted accordingly according to the particle size range of kitchen waste, so that the blade gap on adjacent crushing rollers and the output speed difference of adjacent crushing motors can be set and adjusted according to kitchen waste of different particle size ranges, so as to ensure that different kitchen waste can be completely cut and crushed; in addition, when the particle size range of the kitchen waste entering the crushing device 3 is greater than the preset threshold value, the intelligent control system 9 controls the crushing motor 3-1 to automatically cut off the power and stop running, thereby reducing the safety risk of motor overload caused by the inability to crush the kitchen waste due to the large particle size.

[0034] Preferably, an observation port and an inspection port can be provided between the crushing device 3 and the extrusion device 4 to facilitate real-time observation of whether there are unexpected conditions such as blockage between the crushing device 3 and the extrusion device 4. The material guide height between the crushing device 3 and the extrusion device 4 is not lower than the height of the crushing roller 3-3 to ensure that the kitchen waste is fully and completely crushed.

[0035] like Figure 4 As shown, the extrusion device 4 in this embodiment includes an extrusion shell 4-1 and an extrusion shaft 4-2 movably arranged inside the extrusion shell, a screen 4-3 is fixedly arranged on the periphery of the extrusion shaft 4-2, an extrusion motor 4-4 is arranged at one end of the extrusion device 4, the output end of the extrusion motor 4-4 is fixedly connected to the extrusion shaft 4-2, an active member 4-5 is fixed on the periphery of the extrusion shaft 4-2, and the active member 4-5 in this embodiment is arranged as a spiral blade that can rotate synchronously with the extrusion shaft 4-2, so as to facilitate pushing the kitchen waste to the direction of the driven member 4-6 while rotating to squeeze the kitchen waste, and a driven member 4-6 is arranged at the other end of the extrusion device 4, and the side of the driven member 4-6 close to the active member 4-5 is selectively engaged or separated with the screen 4-3. The output power of the extrusion motor 4-4 drives the active member 4-5 to rotate on the periphery of the extrusion shaft 4-2 and drives the kitchen waste to move toward the driven member 4-6, thereby squeezing the kitchen waste between the active member 4-5 and the driven member 4-6, and the squeezed filtrate is collected by the liquid collecting device 6 from the liquid outlet of the extrusion device after passing through the screen 4-3, and the remaining solid kitchen waste can enter the vertical lifting device 8 through the gap between the side of the driven member 4-6 close to the active member 4-5 and the screen 4-3 and be sent into the drying bin 10, so that the kitchen waste that falls after being crushed can be squeezed until solid kitchen waste with a desired moisture content is obtained.

When the active member 4-5 gradually squeezes the kitchen waste and makes the kitchen waste gradually approach the follower 4-6, the axial squeezing driving force on the kitchen waste gradually increases until it is higher than the elastic force provided by the elastic member to the follower 4-6. At this time, the telescopic sleeve 4-8 is compressed, and the follower 4-6 retracts with the telescopic end of the telescopic sleeve 4-8 to open a gap with the left screen 4-3. At this time, the solid kitchen waste can enter the vertical lifting device 8 through the gap between the follower 4-6 and the left screen 4-3 and be sent into the drying bin 10.

[0037] The elastic force provided by the elastic member in this embodiment can be adjusted, so that the extrusion device can be adjusted accordingly according to different moisture content requirements, further improving the application range of the extrusion device, and improving the extrusion efficiency and extrusion accuracy. The specific adjustment process is as follows: When the required moisture content of the kitchen waste is higher than the preset value, the intelligent control system 9 controls to reduce the elastic force of the elastic member, thereby reducing the difficulty of the follower 4-6 being pushed to separate from the screen 4-3, which is more conducive to opening the gap between the follower 4-6 and the screen 4-3; When the required moisture content of kitchen waste is lower than the preset value, the intelligent control system 9 controls to increase the elastic force of the elastic member, thereby increasing the difficulty of the driven member 4-6 being pushed to separate from the screen 4-3, and increasing the degree of squeezing of the kitchen waste between the active member 4-5 and the driven member 4-6, thereby promoting the production of filtrate to further reduce the moisture content of the kitchen waste.
