[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a garbage cutting device, comprising a hopper and a flattening roller mechanism, a strip-cutting toothed blade mechanism, and a block-cutting toothed blade mechanism installed sequentially from top to bottom within the hopper. The flattening roller mechanism is used to compress garbage into a flat surface of uniform thickness. The strip-cutting toothed blade mechanism is used to cut the flat surface garbage into strips. The block-cutting toothed blade mechanism is used to cut the strips into blocks. The flattening roller mechanism includes two flattening roller units arranged opposite each other with an adjustable spacing. The strip-cutting toothed blade mechanism includes two strip-cutting toothed blade units arranged opposite each other with an adjustable spacing. The block-cutting toothed blade mechanism includes two block-cutting toothed blade units arranged opposite each other with an adjustable spacing.

[0005] Preferably, the center lines of the flattening roller mechanism, the strip cutting toothed knife mechanism, and the block cutting toothed knife mechanism are on the same vertical plane.

[0007] Preferably, a first elastic element is installed on one side between the two roller shafts. The first elastic element is used to drive the two flattening roller units to move towards each other to compress the waste into a flat surface of uniform thickness.

[0008] Preferably, the slicing toothed knife unit includes a slicing toothed knife shaft and a plurality of slicing toothed knives fixedly arranged at equal intervals on the slicing toothed knife shaft, and a second driving member is connected to one end of the slicing toothed knife shaft.

[0009] Preferably, a second elastic element is installed on one side between the two cutting toothed blade shafts. The second elastic element is used to drive the two cutting toothed blade units to move towards each other to cut flat waste into strips.

[0010] Preferably, the dicing toothed blade unit includes a dicing toothed blade shaft and dicing teeth fixedly mounted on the dicing toothed blade shaft, with a third driving member connected to one end of the dicing toothed blade shaft.

[0011] Preferably, a third elastic element is installed on one side between the two cutting tooth shafts. The third elastic element is used to drive the two cutting tooth units to move towards each other to cut the strip-shaped waste into block-shaped waste.

[0012] Preferably, a sealing plate is hinged to the inner top of the hopper to achieve movable sealing of the hopper's feed inlet, and an elastic reset member is installed between the sealing plate and the inner wall of the hopper.

[0013] Preferably, a limiting member for blocking and limiting the sealing plate is installed on the inner wall of the hopper located above the sealing plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention first uses two flattening roller units of a flattening roller mechanism to compress waste into a flat surface of uniform thickness. The flat waste then moves downwards and is cut into strips by two cutting toothed blade units of a cutting toothed blade mechanism. The strips then continue downwards and are cut into blocks by two cutting toothed blade units of a block-cutting toothed blade mechanism. Finally, the blocks fall into a collection bin for crushing by a crushing mechanism. In other words, the waste is processed sequentially into flat surfaces, then strips, and finally blocks before being transported to the crushing mechanism for further crushing. This process, from largest to smallest, ensures that the waste is of relatively uniform size before crushing, thereby improving the subsequent crushing effect. Attached Figure Description

[0028] See Figure 1-8As shown in the figure, as an embodiment of the present invention, a garbage cutting device is provided, including a hopper 1 and a flattening roller mechanism, a strip-cutting toothed knife mechanism, and a block-cutting toothed knife mechanism installed sequentially from top to bottom in the hopper 1. The hopper 1 is a truncated cone with a rectangular cross-section, and its internal channel gradually decreases from top to bottom. The flattening roller mechanism is used to compress garbage into flat surfaces of uniform thickness. The strip-cutting toothed knife mechanism is used to cut the flat surfaces of garbage into strips of garbage. The block-cutting toothed knife mechanism is used to cut the strips of garbage into blocks of garbage. The flattening roller mechanism includes two flattening roller units 2 arranged opposite each other with an adjustable spacing. The strip-cutting toothed knife mechanism includes two strip-cutting toothed knife units 3 arranged opposite each other with an adjustable spacing. The block-cutting toothed knife mechanism includes two block-cutting toothed knife units 4 arranged opposite each other with an adjustable spacing. After the waste is fed into hopper 1, it is first compressed into a flat shape of uniform thickness by two flattening roller units 2 of the flattening roller mechanism. Then, the flat waste moves downward and is cut into strips by two cutting toothed knife units 3 of the strip cutting mechanism. The strips then continue to move downward and are cut into blocks by two cutting toothed knife units 4 of the block cutting mechanism. Finally, the blocks fall into the collection bin for crushing by the crushing mechanism. In other words, the waste is processed in sequence into flat shapes, then strips, and then blocks before being transported to the crushing mechanism for crushing. This process, from large to small, cuts the waste into blocks before crushing, ensuring that the waste is relatively uniform in size before crushing, thereby improving the subsequent crushing effect.

[0029] In this embodiment, the center lines of the flattening roller mechanism, the strip cutting toothed knife mechanism, and the block cutting toothed knife mechanism are on the same vertical plane, so that the waste can be processed in the corresponding process by passing through the flattening roller mechanism, the strip cutting toothed knife mechanism, and the block cutting toothed knife mechanism in a longitudinal sequence from top to bottom, preventing deviation and ensuring the processing effect.

[0030] In this embodiment, the flattening roller unit 2 includes a roller shaft 21 and a roller 22 fixedly mounted on the roller shaft 21. One end of the roller shaft 21 is connected to a first driving member, which drives the roller 22 to rotate. A first elastic member 23 is installed on one side between the two roller shafts 21. The first elastic member 23 is used to drive the two flattening roller units 2 to move towards each other and close together to compress the waste into a flat surface of uniform thickness.

[0031] In this embodiment, the slicing toothed blade unit 3 includes a slicing toothed blade shaft 31 and a plurality of slicing toothed blades 32 fixedly arranged at equal intervals on the slicing toothed blade shaft 31. One end of the slicing toothed blade shaft 31 is connected to a second driving member, which drives the slicing toothed blades 32 to rotate and cut. A second elastic member 33 is installed on one side between two slicing toothed blade shafts 31. The second elastic member 33 is used to drive the two slicing toothed blade units 3 to move towards each other and close together to cut flat waste into strip-shaped waste.

[0032] In this embodiment, the cutting toothed blade unit 4 includes a cutting toothed blade shaft 41 and cutting toothed blades 42 fixedly mounted on the cutting toothed blade shaft 41. One end of the cutting toothed blade shaft 41 is connected to a third driving member, which drives the cutting toothed blades 42 to rotate and cut. A third elastic member 43 is installed on one side between the two cutting toothed blade shafts 41. The third elastic member 43 is used to drive the two cutting toothed blade units 4 to move towards each other to cut the strip-shaped waste into block-shaped waste.

[0033] In this embodiment, the first elastic element 23, the second elastic element 33, and the third elastic element 43 are all spring structures. A track adjustment mechanism is provided between the two roller shafts 21, between the two strip cutting toothed blade shafts 31, and between the two block cutting toothed blade shafts 41. The track adjustment mechanism can adjust the length according to the distance between the two shafts. Its principle is similar to the chain switching gear principle of a bicycle. This is the prior art and will not be described in detail here.

[0034] In this embodiment, sealing plates 5 are hinged to the left and right sides of the inner top of the hopper 1 to achieve movable sealing of the feed inlet of the hopper 1. An elastic reset member 6 is installed between the sealing plate 5 and the inner wall of the hopper 1. The elastic reset member 6 is a spring.

[0035] In this embodiment, a limiting member 7 for blocking and limiting the sealing plate 5 is installed on the inner wall of the hopper 1 located above the sealing plate 5, specifically a limiting block.
