[0075] It can be understood that, in other embodiments, the second sliding blocks can be driven to move by the second sliding block driving members, and the rotating plate 19 can be driven to rotate by the rotating driving member.

[0076] As a technical optimization scheme of the present application, the front surface of the box body 1 is provided with the water inlet 2, a plurality of drainage holes 9 are arranged in the bottom of the box body 1, the sealing member 13 for plugging the plurality of drainage holes 9 is installed on the bottom of the box body 1, and the support columns 3 are installed on the four corner positions of the bottom of the box body 1. The water inlet 2 arranged on the front surface of the box body 1 can conveniently add water to the interior of the box body 1, so as to avoid the problem of less water in the kitchen waste in the box body 1 and poor fermentation effect.

[0077] A kitchen waste fermentation method comprises the fermentation device described above, and further comprises the following steps:

[0078] Step one: the kitchen waste is put into the interior of the box body 1 and falls on the top of the extruding plate 14 for temporary storage by controlling the upward extension of the extension ends of the plurality of first electric telescopic rods 4, driving the top plate 5 and the plurality of components on the top of the top plate 5 to move upward together, and exposing the top opening of the box body 1;

[0079] Step two: if the kitchen waste put into the interior of the box body 1 is mixed with plastic bottles, foam boards and other household wastes, the two first sliding blocks 22 are controlled to drive the extruding plate 14 and the kitchen waste on the top of the extruding plate 14 to move upward together, so that the household wastes in the kitchen waste are penetrated and fixed by the sharp parts at the bottom ends of the plurality of inserting rods 16, and the household wastes fixed on the inserting rods 16 are cut by the plurality of cutting knives 23, which can conveniently discharge the liquid remaining in part of the plastic bottles, and further reduce the volume of the plastic bottles and other household wastes, so as to facilitate the subsequent removal of the household wastes;

[0080] The kitchen garbage includes discarded vegetable leaves, leftovers, rice, peels, eggshells, tea dregs, and bones (chicken bones and fish bones), and the like, which are small in size, soft, and easy to break, and are not easy to be fixed by the inserting rod 16. On the contrary, the sundries in the kitchen garbage include plastic bottles, foam boards, and the like, which are household garbage and are fixed by the inserting rod 16.

[0081] Step three: before the kitchen garbage with more moisture is placed in the box 1, the two rotating plates 19 can be controlled to rotate towards each other, so as to have the effect of extruding and discharging excess moisture from the kitchen garbage, the extruded water can fall downwards from the plurality of third round holes 20 in the extrusion plate 14 to the inner bottom of the box 1, and be discharged from the plurality of drainage holes 9 at the bottom of the box 1; after a part of the moisture in the kitchen garbage is extruded and discharged, the extrusion plate 14 and the kitchen garbage on the top thereof can be moved upwards together through the two first sliding blocks 22, so as to push the kitchen garbage to contact the plurality of cutting knives 23, so that the plurality of cutting knives 23 can cut the kitchen garbage, which is beneficial to the fermentation of the kitchen garbage;

[0082] Step four: during the fermentation of the kitchen garbage in the box 1, the extrusion plate 14 can be repeatedly moved up and down in the box 1 through the two first sliding blocks 22, so as to facilitate the up-and-down turning of the kitchen garbage being fermented, ensure uniform fermentation, and improve the fermentation speed; the extrusion plate 14 can also be controlled to rotate between the two first sliding blocks 22, so as to rotate and stir the kitchen garbage being fermented in the box 1, further improve the stirring effect of the kitchen garbage, and improve the fermentation efficiency of the kitchen garbage in the box 1.

[0083] In the present application, when a user uses the device, the stretching end of the plurality of first electric telescopic rods 4 is controlled to be stretched upwards, the top plate 5 and the plurality of components on the top thereof are driven to move upwards together, so that the top opening of the box 1 is exposed, at this time, the kitchen garbage can be put into the box 1 and fall on the top of the extrusion plate 14 for temporary storage.

[0084] In an embodiment, as the kitchen garbage mixed with plastic bottles, foam boards or large bones and other sundries is put into the inside of the box 1, it is difficult to process these sundries in the subsequent fermentation process of the kitchen garbage, and even affect the efficiency of the kitchen garbage fermentation. At this time, the retractable ends of the plurality of first electric telescopic rods 4 can be controlled to retract, driving the top plate 5 and the plurality of parts on the top thereof to move downward and reset. Then the extrusion plate 14 is controlled to rotate 180 degrees between the two first sliding blocks 22, driving the two rotating plates 19 to rotate to the lower side. Then the two rotating plates 19 are controlled to rotate downward between the two second sliding blocks 17 respectively, so that there is no obstruction on the plurality of third round holes 20 in the extrusion plate 14. Then the extrusion plate 14 and the kitchen garbage on the top thereof are driven upward by the two first sliding blocks 22, so that the plastic bottles, foam boards and large bones in the kitchen garbage are penetrated by the sharp parts at the bottom ends of the plurality of insertion rods 16. After the plurality of insertion rods 16 pass through these sundries, they can pass through the plurality of third round holes 20 in the extrusion plate 14, so that the extrusion plate 14 can continue to move upward, facilitating further extrusion and size reduction of these sundries. Moreover, as the extrusion plate 14 moves downward, the sundries can be in contact with the plurality of cutting knives 23 on the bottom of the top plate 5, so as to cut the sundries inserted and fixed on the insertion rods 16, facilitating the flow of liquid remaining in part of the plastic bottles, further reducing the size of the plastic bottles, and facilitating subsequent workers to sort and recycle the plastic bottles.

[0085] Then the retractable ends of the plurality of first electric telescopic rods 4 can be controlled to extend upward again, driving the top plate 5 and the plurality of parts on the top thereof to move upward together. Then the retractable ends of the two third electric telescopic rods 12 are controlled to extend, driving the collection plate 11 to move to the top of the box 1. At this time, the retractable ends of the plurality of second electric telescopic rods 6 can be controlled to extend upward, driving the moving plate 8 and the plurality of insertion rods 16 to move upward together. The plurality of insertion rods 16 will automatically scrape the sundries inserted and fixed outside thereof through the top plate 5 and fall to the inside of the collection plate 11 for collection in the process of moving upward. At this time, the retractable ends of the plurality of first electric telescopic rods 4 and second electric telescopic rods 6 can be controlled to retract again, driving the top plate 5 and the plurality of insertion rods 16 to extrude the sundries collected by the collection plate 11 downward, further reducing the size of the sundries, and facilitating subsequent workers to collect and classify them.

[0086] If the kitchen garbage contains more fruit peels, other rotten vegetables containing more water, and other kitchen garbage containing water, the water control treatment of this type of kitchen garbage is needed to avoid the problem of unsuccessful fermentation due to too much water. Before placing this type of kitchen garbage inside the box 1, the two rotating plates 19 on the top of the extrusion plate 14 can be controlled to rotate vertically, and then the second sliding block 17 is controlled to move in the second sliding slot 18 towards each other. After the two rotating plates 19 abut each other, the two rotating plates 19 are controlled to rotate away from each other to the state shown in the figure, and then the kitchen garbage is placed on the top of the two rotating plates 19. The two rotating plates 19 are controlled to rotate towards each other, which has the effect of extruding and discharging excess water from the kitchen garbage. The extruded water can fall downward from the third circular hole 20 inside the extrusion plate 14 to the bottom of the box 1, and then be discharged from the drain hole 9 at the bottom of the box 1. Figure 6

[0087] After a part of the water in the kitchen garbage is extruded and discharged, the two rotating plates 19 are rotated back to the original position, and then the second electric telescopic rod 6 is controlled to extend upward by a certain distance, driving the insertion rod 16 to move upward to the position flush with the cutting knife 23. At this time, the insertion rod 16 can maintain the effect of blocking the first circular hole 24 on the top of the top plate 5. Then the extrusion plate 14 and the kitchen garbage on its top are moved upward together by the first sliding block 22, so as to push the kitchen garbage into contact with the cutting knife 23, so that the cutting knife 23 can cut the kitchen garbage. After cutting once, the extrusion plate 14 is controlled to move downward, and then the two rotating plates 19 are controlled to rotate towards each other, so as to stir the kitchen garbage on the top of the two rotating plates 19. Then the two rotating plates 19 are controlled to reset, and the extrusion plate 14 is controlled to move upward to drive the kitchen garbage to move and cut, so as to improve the fineness of the cutting knife 23 in cutting the kitchen garbage, which is beneficial to the fermentation of the kitchen garbage. After the kitchen garbage is cut into small units by the cutting knife 23, the water in the kitchen garbage is more easily separated out, which facilitates the extrusion and drainage of the kitchen garbage by the two rotating plates 19 again.

[0088] ​After the kitchen waste is pretreated, water controlled and cut, the kitchen waste on the top of the extrusion plate 14 can be poured into the inner bottom surface of the box body 1 by rotating the extrusion plate 14 between the two first sliding blocks 22. At this time, the extrusion plate 14 does not need to be controlled to rotate back after rotating, the two rotating plates 19 are kept at the bottom of the extrusion plate 14, and the plurality of second sliding blocks 17 are controlled to be located at both ends of the two second sliding grooves 18 respectively. The two rotating plates 19 are in a downward vertical state and abut against the inner wall of the box body 1. According to the fermentation needs, the substances or water required for fermentation are added into the box body 1 through the water inlet 2 to ensure the smooth progress of the kitchen waste fermentation in the box body 1. During the fermentation process of the kitchen waste in the box body 1, some small amount of plastic products in the kitchen waste will float on the top of the kitchen waste. These plastic products on the top of the kitchen waste will hinder the flow of air and be not conducive to the fermentation of the kitchen waste. At this time, when there are more plastic products on the surface of the kitchen waste, the two rotating plates 19 can be controlled to rotate upward toward each other, so as to facilitate the salvage of the plastic products on the surface of the kitchen waste. Then, after the extrusion plate 14 rotates 180 degrees, the plurality of first electric telescopic rods 4 are controlled to drive the plurality of components on the top thereof to move upward, so that the opening on the top of the box body 1 is exposed. Then, after the extrusion plate 14 is controlled to move upward to the top end in the box body 1, the workers can clean the plastic products salvaged by the two rotating plates 19, and then the extrusion plate 14 and the plurality of first electric telescopic rods 4 can be controlled to reset.

[0089] During the fermentation process of the kitchen waste in the box body 1, the two rotating plates 19 can be controlled to rotate to positions away from the extrusion plate 14, so that the two rotating plates 19 no longer block the plurality of third round holes 20. The extrusion plate 14 is driven by the two first sliding blocks 22 to move up and down repeatedly in the box body 1, so as to facilitate the up-and-down stirring of the kitchen waste being fermented, ensure uniform fermentation and improve the fermentation speed. The two rotating plates 19 can also be controlled to abut against the outer wall of the extrusion plate 14 to block the plurality of third round holes 20. After the extrusion plate 14 is controlled to rotate between the two first sliding blocks 22, the kitchen waste being fermented in the box body 1 can be rotated and stirred, further improving the stirring effect of the kitchen waste.

[0090] After the kitchen waste fermentation in the box 1 is completed, the extrusion plate 14 can be controlled to move upward to the top in the box 1, and at this time, the two rotating plates 19 block the plurality of third round holes 20, the seal 13 at the bottom of the box 1 is opened, so that the fermented kitchen waste in the box 1 can be discharged downward to the container through the plurality of drainage holes 9, and in order to improve the discharge speed of the fermented kitchen waste, the extrusion plate 14 can be controlled to move downward to extrude the kitchen waste in the box 1, so that the discharge speed of the fermented kitchen waste is improved, and the fermented kitchen waste is convenient to take out quickly; after the kitchen waste in the box 1 is completely discharged, water is sprayed into the box 1 through the water inlet 2 to flush the inside of the box 1, facilitating the subsequent use of the box 1.
