Design Of In-vehicle Collecting Device With Farmyard Manure

The paper stems from national scientific and technological support project“Cold region diverse materials efficient stable cooperative fermentation technology ”( project number :2015BAD21B03-02).The paper aimed at design an in-vehicle collecting device with farmyard manure, analyzed the methods of livestock and poultry breeding and livestock and poultry manure treatment method in the rural areas, the dung piled up in the road and ditches, collecting is difficult, therefore, design an auger which can collect the farmyard manure quickly to solve the question which brought out a serious of environmental pollution problems to surrounding residents, and utilized the good farmyard manure resource, alleviate the problems such as organic drop in the soil to improve the land quality.Due to without the relevant research about the collecting device with farmyard manure which piled up in the road and ditches, it is very difficult to collect the drug, so has to use large loader or artificial collection,but the piled drug is disperse which lead to collect difficultly. Therefore, the paper utilized the sectional type auger to collect the farmyard manure, design an assembling and disassembling stand, which can articulate on the side of agricultural trailer, which dragged by the tractor, driven by hydraulic output of tractor, is convenient to collect the farmyard manure.The paper built the model of collecting device with farmyard manure by CATIA, analyzed the working process of collecting device, simulate the working process by the motion simulation analysis and discrete element simulation analysis, to research the influence elements which influence the transmission capacity of auger, and made the structural parameters optimization on the key working part of collecting device.(1) The collecting device with farmyard manure utilized the common agricultural trailer, articulated on the side of the trunk by the assembling and disassembling stand, and went forward by truck and conveyed the piled farmyard manure to truck. When is necessary, it could hitch convenient and quickly, is fast and could save time.(2) To avoid the influence of the traffic road transport, the paper designed a screw frapping and releasing mechanism to complete the working condition transform from the transportation to working condition. When it doesn’t work, it could articulate on the side of the trunk and went by trunk, its transformation power derived from the hydraulic output system of truck, which could be driven by hydraulic, could save manpower and the operation is safe and efficient. And auger could be in coordination with screw frapping and releasing stand to realize comprehensive profiling to improve the adaptation ability of collecting device to complex ditch.(3) The auger is the key working part of the collecting device, and the screw conveyors are widely used in all walks of life. But the working environment is special, easy to produce the problem such as congestion and wear, so auger could operate safe and reliable is related to the parameter design and the dragon blade type selection. Aimed at the question, the paper designed the parameter of auger, utilized the discrete element simulation analysis software EDEM to simulate the working condition of auger, analyze the working parameters of auger, to get the optimal combination scheme.(4) The paper utilized the Design- Expert 8.0 software to treat the simulation result of auger, influence degree on conveying capacity is from small to large is lifting auger inclined angle、screw diameter of auger、rotational speed of auger, according to design goals and influence rule of every factor on conveying capacity can obtain that when the lifting auger inclined angle is 60°, screw diameter of auger is 200 mm and rotational speed of auger is 350 r/min, the conveying capacity is 5.52 t/h, can meet design requirement.At last, the paper processed prototype of in-vehicle collecting device with farmyard manure and made verification test, got the practical test result, verifying the accuracy and rationality of the collecting device with farmyard manure design and theoretical analysis At the same time, the research revises the coefficient of material properties of farmyard mature according the test results, at the same time, providing the reference for the relevant research of auger.
