Description

Technical Field

[0001] This utility model relates to the field of straw recycling technology, and in particular to a crop straw recycling and processing device. Background Technology

[0002] Crop straw refers to the remaining parts of crops after harvest, after the fruits and seeds have been removed. It typically includes stems, leaves, and roots. Common crop straws include rice straw, wheat straw, corn stalks, and cotton stalks. While straw is often considered waste in agricultural production, it actually has significant value. It can be used to make animal feed, compost, building materials, and even for biomass power generation. Furthermore, straw can be mechanically processed into products such as paper and fiberboard, or used as soil mulch to help maintain soil moisture and prevent wind erosion. Recycling and processing equipment refers to devices used to recycle and process waste and resources. These devices typically use mechanical, chemical, and biological methods to convert waste into reusable resources, reducing environmental pollution and promoting resource recycling.

[0003] Existing agricultural straw recycling and processing devices typically consist of several main parts, including a cutting system, a conveying system, a compression system, a drying system, and a storage system. Their working principle generally involves first cutting the straw into smaller segments using the cutting system, then having the conveying system transport the cut straw to the compression system for compression to reduce its volume. The compressed straw is then dried using the drying system, and finally, the processed straw is stored and transported to a designated location for further utilization, such as biomass power generation and as fertilizer.

[0004] However, in actual use, some straw recycling and processing processes are often divided into multiple stages, including harvesting, crushing, collection, transportation and processing. The equipment incompatibility and discontinuous operation process between each stage have resulted in problems such as low efficiency, high energy consumption and increased costs. Especially in rural areas, agricultural machinery is updated slowly and existing equipment has limited functions, making it impossible to achieve efficient integrated processing of straw. In response to the above problems, a crop straw recycling and processing device is proposed. Utility Model Content

[0034] A mixing component is fixedly connected to the bottom of the crushing component. The mixing component includes a transport chamber 12, which is a rectangular box for transporting crushed straw. The top of the transport chamber 12 is fixedly connected to the bottom of the cylindrical cavity 10. An auger 15 is rotatably connected inside the transport chamber 12 to evenly mix the crushed straw and transport it to the subsequent extrusion stage. An output belt 27 is fixedly connected to the top of the support base 1 to transport the extruded straw. An extrusion component is fixedly connected to the top of the support base 1. The extrusion component includes an extrusion box 16, which is a rectangular box. The bottom of the extrusion box 16 is fixedly connected to the top of the support base 1.

A driven wheel 7 is coupled to the inside of the belt 6, and the driven wheel 7 is fixedly connected to one end of the rotating roller 8. Driven by the motor 3, the drive wheel 5 drives the belt 6 to rotate, thereby driving the driven wheel 7 and the rotating roller 8 to rotate, realizing the crushing function. A second motor 13 is fixedly connected to the top of the support base 1, providing stable power output. The drive end of the 3 is fixedly connected to a rotating shaft 14, which drives the auger 15 to rotate, realizing the mixing and conveying functions.

[0036] Working principle: First, the conveyor belt 2 introduces the straw from the outside. The surface of the conveyor belt 2 is provided with anti-slip texture, which can effectively prevent the straw from slipping. The straw is fed into the crushing component located outside the conveyor belt 2. The crushing component includes a cylindrical cavity 10, which has a rotating roller 8 inside. Multiple crushing blades 9 are fixed on the outside of the rotating roller 8. Driven by the motor 3, the driving wheel 5 is driven to rotate through the rotating shaft 4. The power is transmitted to the driven wheel 7 through the belt 6, which finally drives the rotating roller 8 to rotate at high speed. The crushing blades 9 efficiently crush the straw. After being crushed, the straw is initially filtered through the filter plate 11 inside the cylindrical cavity 10 and then falls into the conveyor cavity 12 located below it.

[0037] The transport chamber 12 is a rectangular box, inside which is a screw conveyor 15 driven by a motor 13 through a rotating shaft 14. The screw conveyor 15 can evenly stir and transport the crushed straw forward. During the straw transport process, the spray device set above the transport chamber 12 starts to work. The storage box 23 contains adhesive, and its bottom is connected to the fixed water pipe 25 through the transport water pipe 24. Finally, the spray head 26 installed at the bottom of the fixed water pipe 25 evenly sprays the adhesive on the surface of the straw, providing bonding conditions for subsequent extrusion into blocks.

[0038] Subsequently, the straw treated with the binder is fed into the extrusion assembly by the auger 15. The extrusion assembly consists of an extrusion box 16, which is a rectangular structure. Inside, there is a slidingly connected pressure plate 19 and a baffle plate 28. The pressure plate 19 is driven by a cylinder 17, which pushes the pressure plate 19 back and forth via a telescopic column 18 to apply pressure to the straw. The baffle plate 28 is driven by a cylinder 21, which moves the baffle plate 28 up and down via a telescopic column 22, controlling the pressing and releasing rhythm of the straw to help form compact straw blocks. The pressed straw blocks are then transported to the outside of the equipment by the output belt 27.
