Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, specifically to a plant straw feed crushing mechanism. Background Technology

[0002] Plant straw, as a widely available agricultural byproduct, boasts advantages such as abundant resources, low cost, and suitable nutritional composition, making it an important raw material in feed production. Current technologies for processing plant straw typically include steps such as cutting, crushing, and grinding. However, existing crushing equipment generally suffers from the following shortcomings: the cutting and grinding functions are not effectively integrated, resulting in bulky equipment and complex operation; the cutting device has poor cutting effect on straw fibers, easily leading to clogging and incomplete cutting; some equipment wears out quickly during grinding, lacking a reasonable gap adjustment mechanism, affecting grinding accuracy and efficiency.

[0003] Therefore, there is an urgent need for a plant straw feed crushing mechanism that is compact in structure, stable in operation, and has excellent crushing and grinding effects to meet actual production needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plant straw feed crushing mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A plant straw feed crushing mechanism, comprising: Cutting unit: used for cutting straw, including a crushing tube, with several support frames fixed on the upper and lower sides of its inner wall, bearings between the support frames, and a rotating roller rotatably arranged between two bearings. The outer wall of the rotating roller is equipped with a spiral cutting blade, and the bottom of the crushing tube is equipped with a first feeding port.

[0006] Grinding unit: Located below and connected to the cutting unit, including a storage chamber. The bottom of the storage chamber is provided with a second feeding port. The top of the second feeding port is connected to the grinding hopper. The grinding hopper is provided with a rotatable grinding disc. Several feeding holes are opened on the top edge of the grinding disc. A reasonable gap is provided between the grinding disc and the grinding hopper to achieve effective grinding.

[0007] Drive unit: Used to drive the spiral cutting blade and grinding disc to rotate. It includes a drive shaft, which is sleeved in the inner ring of the bearing and passes through the shaft of the rotating roller and the grinding disc. The bottom of the drive shaft is provided with a driven pulley, which is connected to the driving pulley through the drive belt. The driving pulley is fixed on the output shaft of the motor unit to realize the linkage transmission.

[0008] Furthermore, in order to improve overall operational efficiency and protective structure, this utility model also includes: Feed hopper: Fixed to the top of the crushing pipe and connected to its interior, used to facilitate uniform feeding of straw.

[0009] Support cylinder: Located between the feed hopper and the storage bin, it is used to support and protect the crushing pipe.

[0010] Frame and receiving tray: The frame is set on the outer wall of the storage bin to fix the overall structure of the machine. The receiving tray is set below the first discharge port to facilitate the collection of the ground feed.

[0011] This utility model has the following beneficial effects: 1. This utility model achieves integrated processing of straw from coarse crushing to fine grinding through the close integration of the cutting and grinding units, significantly improving production efficiency. The spiral cutting blade can quickly cut long-fiber straw, and the gap design between the grinding bucket and the grinding disc further refines the particles, meeting the particle size requirements of feed or biomass fuel. A single drive shaft drives the cutting and grinding components, reducing processing steps and equipment footprint, making it suitable for small and medium-sized farms or processing plants. This highly efficient integrated design not only shortens processing time but also reduces energy consumption, saving users operating costs.

[0012] 2. The gap design between the grinding disc and the grinding hopper in the grinding unit of this utility model provides the equipment with flexible particle size control capabilities. By adjusting the gap, users can produce feed or biomass pellets of different particle sizes according to different livestock or processing needs. The uniform distribution of the feed holes ensures that the material is evenly distributed when entering the grinding area, avoiding local over-grinding and improving the quality of the finished product. This flexibility allows the equipment to adapt to various application scenarios, such as cattle and sheep feed, poultry feed, or biomass energy processing, enhancing its market applicability.

[0017] In this embodiment, the crushing tube 2 serves as the main container, housing the cutting process; its inner wall support frame 3 fixes the bearing 4, ensuring the stable rotation of the roller 5. The bearing 4 reduces friction during the rotation of the roller 5, improving operating efficiency. The spiral cutting blade 7 on the outer wall of the roller 5 rapidly cuts the straw; the spiral design enhances continuity and uniformity, reducing clogging. The first discharge port 8 is located at the bottom of the crushing tube 2, facilitating the smooth transfer of the cut straw to the next unit. This structural combination achieves rapid and stable coarse crushing of straw, laying the foundation for subsequent grinding and processing, and is suitable for feed or biomass energy production.

[0018] This utility model also includes: a grinding unit for grinding straw, which is set below and connected to the cutting unit, including a storage bin 9, a second feeding port 10 connected to the bottom of the storage bin 9, a grinding bucket 11 fixed and connected to the top of the second feeding port 10, a grinding disc 12 rotatably arranged inside the grinding bucket 11, a plurality of feeding holes 1201 are opened at the top edge of the grinding disc 12, and there is a gap between the grinding bucket 11 and the grinding disc 12.

[0019] In this embodiment, the storage bin 9 receives the straw transported by the cutting unit and guides the material into the grinding hopper 11 through the second bottom discharge port 10. The grinding hopper 11 cooperates with the grinding disc 12, and the feed hole 1201 on the top edge of the grinding disc 12 ensures that the material enters the grinding area evenly, improving grinding efficiency. The gap design between the grinding hopper 11 and the grinding disc 12 allows for adjustment of the grinding particle size to meet the needs of different feeds or biomass pellets. This structural combination achieves efficient and flexible straw refining, supporting the production of high-quality feed or fuel.

[0020] This utility model also includes: a drive unit for driving the spiral cutting blade 7 and the grinding disc 12 to rotate, including a drive shaft 6, which is sleeved on the inner ring of the bearing 4 and passes through the axis of the rotating roller 5 and the grinding disc 12.

Its design simplifies the operation process, ensuring that the straw enters the cutting unit efficiently and evenly, avoiding material accumulation or blockage. This structure provides a convenient starting point for the entire crushing process, laying the foundation for efficient operation of feed or biomass processing.

[0024] This utility model also includes a support cylinder 18, which is disposed between the feed hopper 1 and the storage bin 9 to protect the crushing pipe 2.

[0025] In this embodiment, the support cylinder 18 is positioned between the feed hopper 1 and the storage bin 9, surrounding and protecting the crushing pipe 2. The function of the support cylinder 18 is to enhance the structural stability of the crushing pipe 2, preventing damage during high-speed cutting or in harsh environments such as dust and moisture. Its design improves the durability and resistance to external impacts of the equipment, ensuring long-term stable operation of the cutting unit. This structure provides reliable protection for the straw processing equipment, extends its service life, and is suitable for the continuous operation requirements of agriculture or biomass processing.
