Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel processing equipment, in particular to a material distribution box. Background Art

[0002] In the biomass fuel production process, its raw materials come from a variety of biological resources, such as agricultural and forestry residues, crop waste straw, wood processing residues, fruit shells and other diversified and diverse biomass-based raw materials. The core of the research and development and application of raw material distribution boxes is to meet the needs of efficient collection, temporary storage and precise distribution of such diverse and complex raw materials. In order to adapt to the supply and demand fluctuations of such raw materials due to seasonal harvesting, the distribution box must be designed with sufficient storage capacity and equipped with a flexible discharging system, usually including multiple discharging ports, to meet the requirements of synchronous operation of different production lines and on-demand material collection.

[0003] However, some biomass fuel raw material distribution boxes on the market still have bottlenecks in the discharge process, which are manifested in technical problems such as unsmooth material discharge and easy blockage, which directly affects the continuous operation efficiency of the entire production line and the consistency of biomass fuel production. Therefore, it is urgent to develop and improve a more optimized discharge structure to ensure that biomass raw materials can flow out of the distribution box steadily, evenly and smoothly, thereby improving the comprehensive efficiency and stability of biomass fuel production.

[0004] The technical problem to be solved by the utility model is to provide a material distribution box.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A material distribution box comprises a frame, a silo fixedly connected to the frame, and a plurality of discharge ports arranged at the lower part of the silo; the upper end of the silo is open, and the width of the lower section is smaller than that of the upper section; two parallel spiral conveying mechanisms are arranged at the lower part of the silo along the length direction of the silo; the spiral conveying mechanism comprises a rotating shaft rotatably mounted on the silo, spiral blades fixedly connected to the rotating shaft and located in the silo, and a reduction motor installed at one end of the silo and fixedly connected to the rotating shaft at the output end; the spiral blades of the two conveying mechanisms are parallel and do not interfere with each other; the upper end of the discharge port extends to the corresponding two sides of the silo respectively.

[0007] Preferably, a mounting seat is fixedly connected to the frame, and the reduction motor is fixedly connected to the mounting seat.

[0009] Preferably, a guardrail is provided on the outer side of the maintenance platform.

[0010] Preferably, the maintenance platform is made of patterned steel plate.

[0011] The above technical solution has the following advantages:

[0012] The utility model focuses on improving the working mechanism of the biomass fuel raw material distribution box and creatively introduces a double-helix reverse conveying method. This unique design includes two screw conveying mechanisms with opposite operating directions, which work together to enable the biomass raw materials inside the distribution box to achieve two-way circulation. The advantage of this design is that it can ensure that all discharge ports are fully filled at all times to avoid vacancies or uneven stacking. In this way, the utility model effectively ensures that the flow state of the biomass raw materials at the discharge port of the distribution box is always in a stable, uniform and smooth state, greatly reducing production interruptions or efficiency losses caused by unstable material supply. As a result, the continuity, stability and comprehensive efficiency of the entire biomass fuel production process are significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS
