Description

Technical fields:

[0001] This utility model belongs to the field of shredder technology, and specifically refers to a shredder. Background technology:

[0002] Shredders, widely used in solid waste treatment and resource recycling, primarily function to shear and crush materials using a set of blades. In actual operation, to control the output particle size, a filter assembly (such as a screen or grid) is typically installed below the shredding blades. Materials that do not meet the size requirements are intercepted and further crushed. However, traditional shredders often use fixed installation structures for their filter assemblies, requiring the entire shredder to be disassembled for replacement. This disassembly and assembly is inconvenient, inefficient, and incurs high maintenance labor costs. Summary of the Invention:

[0003] The purpose of this utility model is to provide a shredder with a simple structure, reasonable design and low cost. It adopts a split structure, which allows the filter component to slide laterally into or out of the shredding chamber, realizing quick disassembly and assembly of the filter component.

[0004] This utility model is implemented as follows:

[0005] A shredder includes a housing and a shredding chamber disposed within the housing. A shredding blade assembly is horizontally disposed within the shredding chamber, and a filter assembly is located below the shredding blade assembly. The filter assembly is slidably fitted within the shredding chamber. A replacement window communicating with the shredding chamber is provided on the housing on one side of the filter assembly. The replacement window is a replacement channel for the filter assembly to slide horizontally into or out of the shredding chamber. A replacement end cover that can completely seal the replacement window is detachably connected to the replacement window.

[0006] In the aforementioned shredder, an inner sliding guide rod is horizontally mounted inside the shredding chamber located directly below the front and rear sides of the shredding blade assembly, and the front and rear sides of the filter assembly are respectively slidably mounted on the corresponding inner sliding guide rods.

[0007] In the aforementioned shredder, the filter assembly includes a filter base frame and a filter screen mounted on the filter base frame. The filter base frame is slidably fitted inside the shredding chamber, and a filter handle is provided on the side wall of the filter base frame near the replacement window.

[0008] In the aforementioned shredder, the outer wall of the replacement end cover is provided with an end cover handle, and the inner end face of the replacement end cover is provided with a limiting post. The end of the limiting post abuts against the corresponding side wall of the filter assembly, and a positioning space is formed between the limiting post and the shredding chamber to fix the lateral position of the filter assembly.

[0009] In the aforementioned shredder, an external support frame is provided on the casing located outside the replacement window. This external support frame serves as a replacement platform for the filter assembly, which is laterally slidable out of the shredding chamber.

[0010] In the aforementioned shredder, the front and rear sides of the external support frame are each provided with an external sliding guide rod along the transverse direction, and the front and rear sides of the filter assembly are respectively slidably mounted on the corresponding external sliding guide rods.

[0011] The outstanding advantages of this utility model compared to the prior art are:

[0012] This utility model has a simple structure, reasonable design and low cost. The filter component and the housing adopt a split structure, and a replacement window is opened on the side wall of the shredding chamber, so that the filter component can slide laterally to enter or exit the shredding chamber, thereby realizing the quick disassembly and assembly of the filter component.

[0018] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4:

[0019] A shredder includes a housing 1 and a shredding chamber disposed within the housing 1. A shredding blade assembly 2 is horizontally disposed within the shredding chamber, and a filter assembly 3 is located below the shredding blade assembly 2. The filter assembly 3 is slidably fitted within the shredding chamber. A replacement window 4 communicating with the shredding chamber is provided on the housing 1 on one side of the filter assembly 3. The replacement window 4 is a replacement channel for the filter assembly 3 to slide horizontally into or out of the shredding chamber. A replacement end cover 5 that can completely seal the replacement window 4 is detachably connected to the replacement window 4.

[0020] This utility model has a simple structure, reasonable design and low cost. The filter component 3 and the housing 1 adopt a split structure, and a replacement window 4 is opened on the side wall of the shredding chamber, so that the filter component 3 can slide laterally to enter or exit the shredding chamber, thereby realizing the quick disassembly and assembly of the filter component 3.

[0021] The transverse sliding fit structure of the filter component 3 in the shredding chamber can be a groove structure opened transversely on the wall of the shredding chamber. The filter component 3 slides fit in the groove structure. In this embodiment, an inner sliding guide rod 6 is installed transversely in the shredding chamber located directly below the front and rear sides of the shredding blade group 2. The front and rear sides of the filter component 3 are respectively slidably installed on the corresponding inner sliding guide rod 6.

[0022] Meanwhile, the specific structure of the filter assembly 3 is as follows: the filter assembly 3 includes a filter base 7 and a filter screen 8 disposed on the filter base 7. The filter base 7 is slidably fitted inside the shredding chamber, and a filter handle 9 is provided on the side wall of the filter base 7 near the replacement window 4. The filter handle 9 allows the filter base 7 to be moved laterally by manual pushing.

[0023] Furthermore, to facilitate the placement of the replacement end cover 5 on or from the replacement window 4, a handle 10 is provided on the outer wall of the replacement end cover 5. Additionally, to ensure the lateral position of the filter assembly 3 within the shredding chamber is relatively fixed, a limiting post 11 is provided on the inner end face of the replacement end cover 5. The end of the limiting post 11 abuts against the corresponding side wall of the filter assembly 3, and a positioning space is formed between the limiting post 11 and the shredding chamber to fix the lateral position of the filter assembly 3. Moreover, the replacement end cover 5 can be hinged to the housing 1 on one side and fixedly connected to the housing 1 on the other side via a latch. In this embodiment, the replacement end cover 5 is fixed to the housing 1 with fastening screws.

[0024] Furthermore, to facilitate the placement of the filter assembly 3 when it enters and exits the shredding chamber, an external support frame 12 is provided on the housing 1 located outside the replacement window 4. This external support frame 12 serves as a replacement platform for the filter assembly 3, which is laterally slidable out of the shredding chamber. In this embodiment, to facilitate pushing the filter assembly 3 into or out of the shredding chamber, external sliding guide rods 13 are laterally mounted on both the front and rear sides of the external support frame 12, and the front and rear sides of the filter assembly 3 are slidably mounted on the corresponding external sliding guide rods 13.

[0025] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
