In the present embodiment, the words such as "left", "right", "inner", "outer", etc. describing the directional relationship are only for convenience of description of the embodiment, and are not to be considered as limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

The utility model discloses not only can be used for kitchen garbage's breakage, still can be used to the breakage of rubbish such as wrapping bag, plastics.

Fig. 1 to 4 show an embodiment of the present invention. This embodiment provides a kitchen garbage roll crusher. This kitchen garbage roll crusher includes casing 13 and establishes two sets of meshing crushing knife tackle in casing 13, and casing 13 top is opened as the feed inlet, and feed inlet department leaks hopper-shaped feed bin 1 through bolt fixedly connected with. The bottom of the shell 13 is provided with a discharge opening 8.

One of the two groups of meshing crushing cutter sets is a driving meshing crushing cutter set, and the other group is a driven meshing crushing cutter set. Each group of meshing crushing cutter group comprises a cutter shaft 10 and a plurality of spacer bushes 6 and crushing cutters 7 arranged on the cutter shaft 10. The crushing cutters 7 of the two groups of meshing crushing cutter groups are arranged in a staggered manner. As shown in fig. 3, the two ends of the knife shaft 10 are a cylindrical first connecting portion 101 and a cylindrical second connecting portion 102, a hexagonal prism-shaped mounting portion 102 is arranged between the two connecting portions, and six edges of the mounting portion 102 are provided with chamfers. As shown in fig. 4, the crushing blade 7 has a disk shape, a hexagonal coupling hole 71 at the center thereof to be fitted to the mounting portion 102, and crushing teeth 72 at the outer periphery thereof in a ratchet shape. Spacer 6 also has a hexagonal mounting hole in the center that matches mounting portion 102. The spacer 6 and the crushing cutter 7 can be installed on the installation part 102 of the cutter shaft 10 at intervals by adopting an interference fit mode and the like.

Because the middle parts of the spacer bush 6 and the crushing cutter 7 are provided with the holes matched with the hexagonal prism-shaped mounting part 102, the spacer bush 6 and the crushing cutter 7 can be effectively fixed on the cutter shaft 10, and therefore, other fastening parts are not needed during installation, and the mechanism is simple.

When the cutter shaft 10 rotates, the power can be directly transmitted to the crushing cutter 7 due to the limiting and special-shaped transmission effects of the six edges of the mounting part 102, and the crushing cutter 7 is driven to rotate to complete crushing work. When the crushing knife 7 is worn or damaged, the knife shaft 10 is only required to be unloaded from the kitchen waste roll crusher, and then the corresponding blade is taken down for replacement, so that the replacement and maintenance are convenient.

As shown in fig. 1 and fig. 2, two cutter shafts 10 are mounted on the side walls of two ends of a housing 13 through bearings 5, wherein a first connecting portion 101 of the cutter shaft 10 actively engaged with a crushing cutter set is connected with the output end of a speed reducer 3 through a coupler 4, and the output end of the speed reducer 3 is connected with the output end of a motor 2. The coupling 4 can prevent the motor 2 from being damaged by overload caused by the blocking and stopping of the meshing crushing cutter set.

The second connecting part 102 of the cutter shaft 10 of the driving meshing crushing cutter group is meshed with the driven gear 14 of the cutter shaft 10 of the driven meshing crushing cutter group through the driving gear 12. The driving gear 12 and the driven gear 14 are fixed on the cutter shaft 10 through mounting key blocks. One ends of the cutter shafts 10 of the two groups of meshing crushing cutter groups, which extend out of the driving gear 12 and the driven gear 14, are respectively connected with bearings in two bearing blocks 11.

In order to facilitate installation and use, the shell 13, the speed reducer 3, the bearing seat 11 and the motor 2 of the kitchen waste roll crusher are fixedly connected onto the support 9 through bolts, the kitchen waste roll crusher has a positive and negative rotation function, objects with high hardness such as metal are encountered in the crushing process or a winding phenomenon occurs, the crushing cutter set can rotate reversely, and foreign matters or faults are conveniently discharged.

In the present embodiment, the fitting manner of the spacer 6 and the crushing cutter 7 with the cutter shaft 10 is not limited to interference fit, and a fixed connection manner such as welding or pin connection may be adopted. The combination of the motor and the speed reducer may be replaced by another driving device such as an internal combustion engine and a hydraulic power system. The hopper 5 can also be fixedly connected at the feed inlet by adopting welding, integral forming with the shell and other modes.

When the crushing device is used, the motor 2 is started, the motor 2 drives the driving crushing cutter set to rotate through the speed reducer 3 and the coupler 4, and the driving crushing cutter set drives the driven driving crushing cutter set to rotate through the driving gear 12 and the driven gear 14; at the moment, organic solid wastes such as kitchen waste and the like are poured into the kitchen waste roll crusher through the bin 1 to crush the roll crusher; and discharging the crushed garbage from a bottom discharge opening 8 of the kitchen garbage roll crusher.
