The application provides a kind of intelligent adaptive low-loss rape harvester based on management and control model, including main controller and multiple adjusting systems connected with main controller;Wherein, rape plant density adaptive adjusting system adjusts cutting table cutting speed, conveying spiral rotating speed, whole machine operation advancing speed according to rape plant density in real time;Adaptive raking adjusting system adjusts guide vane width and straw divider gap according to straw thickness and feeding amount;Chain dynamic adjusting system adjusts the rotating speed of transmission sprocket in raking chain conveying unit according to cutting table vibration amplitude in real time;Rape plant height adaptive adjusting system adjusts the height of cutting table according to the height of rape plant and / or degree of stacking and lodging;Rape plant hardness adaptive adjusting system adjusts the cutting speed of cutting table according to straw hardness.The application can realize intelligent adaptive adjustment in all working conditions, adapt to different rape plant density, straw biological state of field environment, and improve the versatility and operation stability of agricultural machinery.

The invention discloses a method for synergistically preparing tea saponin and a microbial flocculant, which comprises the following steps: preparing tea saponin crude extract and oil-tea cake extract from oil-tea cake, preparing the extract into an oil-tea cake culture medium, inoculating a flocculation functional bacteria seed solution for culturing, and preparing a pure microbial flocculant product. Preparing the tea saponin into a solution, mixing the solution with a tea saponin crude extract after oil removal and a coagulant aid solution for flocculation, and standing to obtain liquid tea saponin; and carrying out primary concentration, extraction, decoloration and secondary concentration on the liquid tea saponin to obtain the solid tea saponin. According to the method for synergistically preparing the tea saponin and the microbial flocculant, the microbial flocculant and the tea saponin which are high in yield and purity can be prepared at the same time, circulating sharing of water and an organic solvent can be achieved, and resource utilization of the oil tea cakes is achieved. The method also has the advantages of simple process, convenience in operation, low cost, environmental friendliness and the like, and is high in use value and good in application prospect.
