[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0021] Embodiment 1, as Figures 1-5 As shown, a drum-type mechanical sorting machine comprises a lower shell 1 and an upper shell cover 2, a V-shaped discharge port 3 is arranged in the middle of the bottom of the lower shell 1, a coarse material outlet 4 is opened on one side of the lower shell 1, and a material guide inclined plate 5 is arranged in the coarse material outlet 4. In the present embodiment, the material guide inclined plate 5 is connected to one side of the V-shaped discharge port 3, so that the cross section of the material guide inclined plate 5 and the V-shaped discharge port 3 forms an "N"-shaped structure; a rotating shaft 7 is rotatably connected to the upper surface of the lower shell 1 through a bearing seat 6, one end of the rotating shaft 7 passes through the lower shell 1 and is transmission-connected to the driving end of a driving motor 8; at least two supporting sleeves 9 are fixedly sleeved on the surface of the rotating shaft 7, and one end of a plurality of supporting shafts 10 is fixedly connected to the outer surface of the supporting sleeve 9, and the other end of the supporting shaft 10 is fixedly connected to the inner side wall of a filter cartridge 11, and a plurality of filter ports 12 are evenly opened on the surface of the filter cartridge 11, and the lower surface of the filter cartridge 11 is vertically opposite to the V-shaped discharge port 3, and the end of the filter cartridge 11 is opposite to the upper end of the material guide inclined plate 5;

[0022] The upper shell cover 2 is fixedly installed above the lower shell 1, and a feed chamber 13 is fixedly installed on the side of the lower shell 1. The feed chamber 13 is connected to the inner cavity of the lower shell 1, and the feed chamber 13 corresponds to the inner cavity of one end of the filter cartridge 11. A spiral screw motor 14 is installed on the outside of the feed chamber 13, and the driving end of the spiral screw motor 14 is transmission-connected to the spiral screw 15, and the spiral screw 15 is rotatably connected to the inside of the feed chamber 13.

[0023] Working principle:

[0024] During use, first, the kitchen waste is fed into the feeding chamber 13. Thus, through the rotation of the spiral screw 15 in the feeding chamber 13, the kitchen waste can be evenly and uniformly conveyed into the inner cavity of the filter cylinder 11. Then, the drive motor 8 is used to drive the rotation shaft 7 to rotate, and then the filter cylinder 11 can be driven to rotate. When the kitchen waste rotates in the inner cavity of the filter cylinder 11, small pieces of garbage such as food residues can pass through the filter openings 12 on the surface of the filter cylinder 11 and fall into the V-shaped discharge port 3. Finally, it can be discharged through the V-shaped discharge port 3. While large pieces of garbage such as big bones gradually move towards the coarse material outlet 4 during the rotation of the filter cylinder 11, and then flow out from the end of the filter cylinder 11. Through the guiding effect of the inclined surface of the guiding inclined plate 5, the large pieces of garbage such as big bones can be discharged from the coarse material outlet 4. Thus, the effect of sorting small pieces of garbage such as food residues and large pieces of garbage such as big bones in the kitchen waste is achieved.

[0025] Embodiment 2, as a further preferred solution of Embodiment 1, a plurality of semi-spiral blades 16 are installed on the inner side wall of the filter cylinder 11, and the spiral directions of the respective semi-spiral blades 16 are the same. Through the spiral guiding effect of the respective semi-spiral blades 16, the kitchen waste conveyed into the inner cavity of the filter cylinder 11 can gradually move along the axial direction of the filter cylinder 11 towards the coarse material outlet 4 during the rotation of the filter cylinder 11 itself, so that the large pieces of garbage can flow out from the end of the filter cylinder 11.

[0026] Embodiment 3, as a further preferred solution of Embodiment 1, the filter cylinder 11 is arranged as a frustum-shaped cylindrical structure, and the large circular surface of the filter cylinder 11 is close to the coarse material outlet 4. By arranging the filter cylinder 11 as a frustum-shaped cylindrical structure, the bottom surface of the filter cylinder 11 is always an inclined surface, and the lower end surface close to the coarse material outlet 4 is lower than the lower end surface close to the feeding chamber 13. Thus, it is effectively ensured that the kitchen waste can move towards the coarse material outlet 4 during the rotation of the filter cylinder 11 itself, thereby ensuring the sorting effect of small pieces of garbage and large pieces of garbage.

[0027] Embodiment 4, as Figures 4 to 5 shown, as a further preferred solution of Embodiment 1, the rotation shaft 7 includes an intermediate shaft sleeve 71, and a drive shaft 72 and a driven shaft 73 are coaxially and fixedly inserted at both ends of the intermediate shaft sleeve 71. The drive shaft 72 is in transmission connection with the drive end of the drive motor 8, and the driven shaft 73 is rotationally connected with the bearing seat 6.

[0028] Therefore, when it is necessary to disassemble, clean and maintain the filter cartridge 11, the drive shaft 72 and the driven shaft 73 at both ends of the intermediate shaft sleeve 71 can be directly pulled out from the intermediate shaft sleeve 71, so that the drive shaft 72 and the driven shaft 73 are separated from the intermediate shaft sleeve 71, and the disassembly, cleaning and maintenance work of the entire filter cartridge 11 component can be realized. The whole process is convenient and fast, and there is no need to disassemble the drive end of the drive motor 8 and other operations.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
