Description

Technical Field

[0001] This utility model relates to the field of environmental protection, specifically a multi-stage material crusher. Background Technology

[0002] In the fields of environmental protection and biomass energy utilization, the effective treatment of agricultural and forestry waste such as tree branches is particularly important. Currently, various tree branch shredding equipment exists on the market, with single-stage or multi-stage shredders being the most common. However, existing multi-stage shredders often have the following shortcomings when processing tree branches: First, the first stage of shredding often uses ordinary blade cutting, which is inefficient and easily leads to uneven material size, affecting subsequent processing results; second, the second stage of crushing often uses simple stirring or hammering methods, which have limited fineness of the material and are difficult to achieve the required high-quality fine crushing; third, the overall structure of the equipment is complex, energy-intensive, and has high maintenance costs. Therefore, developing a more efficient, energy-saving, and superior tree branch multi-stage shredder is particularly urgent. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage material crusher to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage material crusher, comprising a support frame, a crusher, and a mixer. A motor is fixedly installed on one side of the support frame, a first transmission wheel is installed on one side of the support frame, a second transmission wheel is installed on the top side of the support frame, a transmission belt is installed between the second transmission wheel and the first transmission wheel, and a transmission belt is installed between the first transmission wheel and the output end of the motor. The crusher is installed on the top of the support frame, a first rotating shaft is installed inside the crusher via bearings, and the first rotating shaft is drivenly connected to the second transmission wheel. A high-speed cutter is installed around the outside of the first rotating shaft. The mixer is fixedly installed in the middle of the support frame, a second rotating shaft is installed inside the mixer via bearings, and the second rotating shaft is drivenly connected to the first transmission wheel. Threaded blades are installed around the outside of the second rotating shaft.

[0005] During operation, the material to be crushed is poured into the crusher. The support drive rotates the first transmission wheel, which in turn drives the second transmission wheel to rotate at high speed. The second transmission wheel then drives the first shaft to rotate. The high-speed cutter is made of high-strength alloy material, featuring sharp blades and an optimized blade arrangement. It can efficiently cut branches, reduce cutting resistance, and improve crushing efficiency. Simultaneously, by adjusting the speed of the high-speed cutter and the feeding speed, preliminary uniform crushing of branches can be achieved, laying a good foundation for subsequent processing. The material inside the crusher can fall naturally into the grinder by gravity. The grinder innovatively adopts a spiral blade design. These spiral blades not only have strong mixing capabilities but also generate strong shearing force during rotation, further refining the branch fragments. Both the grinder and the spiral blades are designed from large to small. The special shape and arrangement of the spiral blades ensure thorough mixing and uniform refinement of the material in the grinding chamber, greatly improving the crushing quality. The entire equipment has been structurally optimized. This device is driven by a single motor, reducing unnecessary transmission components and lowering energy consumption.

[0006] Preferably, the pulverizer has a first discharge port at the bottom and a feed port at the top.

[0007] Materials can enter the crusher through the feed inlet at the top of the crusher, and the processed materials inside the crusher can be discharged through the first discharge outlet.

[0008] Preferably, the shredder has a second discharge port on one side of its bottom and a feed port on its top.

[0009] Materials can enter the crusher through the feed inlet at the top of the crusher, and the processed materials inside the crusher can be discharged through the second discharge outlet.

[0010] Preferably, the pulverizer is located above the mixer, and the first discharge port is perpendicular to the feed port of the mixer.

[0011] Because the crusher is located above the mixer and the first discharge port is set vertically to the feed port of the mixer, the material can be accurately introduced into the mixer for secondary crushing after the crusher has performed initial crushing.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This invention combines a first-stage high-speed rotating high-speed cutter with a second-stage spiral blade, employing multi-stage crushing to significantly improve the crushing efficiency and quality of branches, ensuring uniform and fine crushing of materials. Furthermore, the equipment has a compact structure and reasonable component design, facilitating daily maintenance and repair, reducing maintenance costs, and can adapt to the crushing needs of different types and diameters of branches, exhibiting strong versatility and flexibility.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention proposes a multi-stage material crusher, including a support 1, a crusher 2, and a mixer 3. A motor 101 is fixedly installed on one side of the inside of the support 1. A first transmission wheel 102 is installed on one side of the support 1. A second transmission wheel 103 is installed on the top side of the support 1. A transmission belt is installed between the second transmission wheel 103 and the first transmission wheel 102. A transmission belt is installed between the first transmission wheel 102 and the output end of the motor 101. The crusher 2 is installed on the top of the support 1. A first rotating shaft 201 is installed inside the crusher 2 through bearings, and the first rotating shaft 201 is connected to the second transmission wheel 103. A high-speed cutter 202 is installed around the outside of the first rotating shaft 201. The mixer 3 is fixedly installed in the middle of the support 1. A second rotating shaft 301 is installed inside the mixer 3 through bearings, and the second rotating shaft 301 is connected to the first transmission wheel 102. A threaded blade 302 is installed around the outside of the second rotating shaft 301.

[0031] The working principle of the multi-stage material crusher based on Embodiment 1 is as follows: During use, the material to be crushed is poured into the crusher 2. The support 1 drives the first transmission wheel 102 to rotate, which in turn drives the second transmission wheel 103 to rotate at high speed. The second transmission wheel 103 then drives the first rotating shaft 201 to rotate. The high-speed cutter 202 is made of high-strength alloy material, featuring sharp blades and an optimized blade arrangement. This allows for efficient cutting of branches, reducing cutting resistance and improving crushing efficiency. Simultaneously, by adjusting the rotational speed of the high-speed cutter 202 and the feeding speed, preliminary uniform crushing of the branches can be achieved, laying a good foundation for subsequent processing. The material inside 2 can fall naturally into the crusher 3 by gravity. The crusher 3 innovatively adopts the design of spiral blades 302. These spiral blades 302 not only have strong mixing ability, but also generate strong shearing force during rotation, further finely crushing the branch fragments. Both the crusher 3 and the spiral blades 302 are designed from large to small. The special shape and arrangement of the spiral blades 302 ensure that the material is fully mixed and uniformly refined in the crushing chamber, which greatly improves the crushing quality. The structure of the entire equipment has been optimized. This device is driven by a single motor 101, which reduces unnecessary transmission parts and lowers energy consumption.

[0032] This device significantly improves the crushing efficiency and quality of branches by combining the first-stage high-speed rotating high-speed cutter 202 with the second-stage threaded blade 302, ensuring uniform and fine crushing of materials. The equipment has a compact structure and reasonable component design, which facilitates daily maintenance and repair, reduces maintenance costs, and can adapt to the crushing needs of branches of different types and diameters, with strong versatility and flexibility.

[0033] Example 2

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, the multi-stage material crusher proposed in this utility model, compared with the first embodiment, further includes: a first discharge port 203 is provided at the bottom of the crusher 2, and a feed port is installed at the top of the crusher 2; a second discharge port 303 is provided on one side of the bottom of the pulverizer 3, and a feed port is installed at the top of the pulverizer 3; the crusher 2 is located above the pulverizer 3; and the first discharge port 203 is perpendicular to the feed port of the pulverizer 3.

[0035] In this embodiment, as Figure 2 As shown, materials can enter the crusher 2 through the feed inlet at the top of the crusher 2, and the processed materials inside the crusher 2 can be discharged through the first discharge outlet 203; as Figure 3 As shown, materials can enter the crusher 3 through the feed inlet at the top of the crusher 3, and the processed materials inside the crusher 3 can be discharged through the second discharge outlet 303; as Figure 1 As shown, because the crusher 2 is located above the mixer 3 and the first discharge port 203 is set vertically to the feed port of the mixer 3, the material can be accurately introduced into the mixer 3 for secondary crushing after the crusher 2 performs initial crushing.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
