Research status and prospect of grape soil clearing and cold-proof cloth recycling mechanization technology

At present,the grape soil clearing and cold-proof cloth recycling is still mainly manual operation,which is characterized by high labor intensity,low efficiency and high cost.In addition,this operation is time-sensitive,which is not conducive to grape growth if it is too early or too late.Therefore,it is urgent to study a feasible grape soil clearing and cold-proof cloth recycling machine.It was expounded the main types,working principle,and characteristics of the grape soil clearing and cold-proof cloth recycling machine at home and abroad.It was also analyzed the key components.From two aspects of agronomy and agricultural machinery,it was proposed the mechanization development restricting factors and existing problems of machine.From the aspect of agronomy,it was pointed that the non-standard of planting patterns reduces the versatility of machines and tools.From the aspect of agricultural machinery,it was pointed that the unilateral operation mode,ridge above operation mode and low level of intelligence are not conductive to high quality soil clearing operation.The material and method of soil clearing mechanism lead to damage of grapevine and low efficiency of this operation.The unreasonable structure form and operation angle of cold-proof cloth winding mechanism and the mismatching of its rotation rate with the forward speed lead to the low winding quality of the cold-proof cloth.In view of the existing problems,it puts forward that it needs to cultivate new cold-proof grape varieties,develop greenhouses and facilities for cultivation.It must standard the grape planting and management mode.It also can develop new cold-proof materials to replace cold-proof soil.In terms of the machines themselves,it needs to implement the ridge-operation type machinery,research and develop separate power bilateral machinery or turnover type machinery.And rigid and flexible combined soil clearing components are adopted.There are other measures that the PID control technology to adjust rotation rate of the cold-proof cloth winding mechanism,integration of mechanical and electrical hydraulic technology to improve the degree of automation and intelligence,et al.It can provide a new development idea for the soil clearing and cold-proof cloth winding operation.Moreover,it promotes the improvement of grape spring soil clearing mechanization.
