The Design Of Soil-rock Seperator-mixer

For Ningxia Helan Mountain grape cultivation base, The traditional fixed value of mining operations in the ditch is tedious, time consuming, high labor intensity, low work efficiency situation and so on; The design scheme of earth rock separating and mixing machine is worked out, which is a collection of soil and rock separation, soil and farm manure mixed and backfill planting ditch and so on. Improved artificial stone picking, fertilization,rotary tillage, mining machinery and other traditional operation mode of operation; To a certain extent, it saves manpower and material resources, and improve the work efficiency of the grape planting planting ditch digging operation.Based on the analysis of rock picker and mixing machine on the existing soil. By using the TRIZ theory and the design idea of integrated innovation, the whole design scheme of "soil and rock separation+soil, the uniform mixing of farm manure+Backfill planting furrow+the gravel collection" was proposed; Combined with the local soil quality and the Characteristics and requirements of planting furrow digging operation, the main design parameters were determined; Drawing on the working principle and structural characteristics of the screening machine, the circular vibrating screen of the earth rock separation part is designed, which can quickly and effectively complete the separation of soil and gravel, and the diameter is more than 30mm of the gravel transported to the set box; Drawing on the working principle and structure characteristics of the mixing machine.The biaxial mixer of material mixing device is designed, which can make the soil, manure fast and efficient mixing and backfill planting furrow. And can effectively avoid the mixture in the filamentous or block and other grass stem long time winding in the spiral blade caused by blockage; Finally, according to the total power consumed by the equipment and the spatial structure and characteristics of the device, the design of the driving device and the trailer frame are carried out. In this paper, the screening efficiency of circular vibrating screen is studied, and the optimum design is combined with the optimization design of the relevant parameters to achieve the best efficiency; The finite element analysis of the spiral shaft in the mixing device is carried out, and the optimal design of the screw shaft is carried out according to the stress and the bending deformation.The device has the advantages of compact structure, reliable work, high work efficiency, and can complete the soil and rock separation and the mixed material backfill and other planting ditch excavation work, the workload per hour is 140t/h.
