Design Of The Fertilizer Application Machine For Grape Inorganic Fertilizer

Grape is the dominant industry in Ningxia,the region has a large area of grape growing,there is a trend of sustainable development.The application of fertilization to grape is an essential part in the growth of grape,and the effect of Fertilization on the quality and yield of grape is very important.Development of equipment of grape fertilization in Ningxia region is at the preliminary stage and the mechanical problems of fertilizer, fertilizer regulation is not accurate uniformity,low productivity,low level of mechanization and high production cost.These problems need to be solved at present,which have seriously affected the mechanization and standardization of the application of the fertilizer application in Ningxia area.To solve the above problems, the advantages of the structure and function of the equipment at home and abroad based on grape fertilization,according to the Ningxia grape planting pattern design,carry out fertilization is suitable for Ningxia area of grape inorganic fertilizer machine.The machine is mainly composed of a machine frame.a three-point suspension mechanism,a fertilizer box,a fertilizer adjusting device,power transmission system and furrow opener, etc. parts.Through the use of SolidWorks and AutoCAD drawing software for the parts design,and improve the design of the main part of the fertilizing machine,and stress analysis of key components,completed the optimization of fertilization machine and tractor power matching.The main contents of this paper are as follows:First of all,the fertilizer application of the device is designed.Through the analysis of the traditional fertilization method,a new type of fertilizer adjustment device is designed, which is composed of a dial,a screw nut,a pointer, a lead screw,a connecting rod,a fertilizer baffle and a regulating valve.The device is fixed on the rear of the machine frame and the fertilizer box,and when the amount of the fertilizer is needed,the control valve can be rotated clockwise to reduce the amount of fertilizer applied according to the requirement.On the contrary,the counterclockwise rotation of the valve to increase the amount of fertilizer,according to the scale of quantitative regulation of fertilization amount.Secondly,the structure of the transmission system is improved.The transmission system of fertilization inorganic fertilizer on the traditional grape machine was improved,and joined the vane type fertilizer apparatus.Fertilizing machine improved in tractor drive.two wheel division,do not interfere with each other, respectively complete fertilizer and fertilizer transport function.Furthermore.the selection of the auger and the determination of main technical parameters.The type selection of the auger conveying device is made,and the rotary form of the auger is determined as the right hand,and the blade is a solid spiral blade.The main design parameters of the auger conveying device are calculated and analyzed.Then,the selection and analysis of the force on the opener,completing the power fertilization machine and tractor matching optimization work. Completed the selection of the opener,which comprises a shovel head and shovel column.The opener of the mechanical analysis,to determine the working resistance of fertilizing machine by the opener in the working process of the size of the.The optimum power range of the tractor is determined by the working resistance,and the dynamic matching optimization of the machine and the tractor is completed.Finally,a field experiment was conducted to verify the performance of the fertilizer application. Through the above design improvement,and complete the development of fertilizer,and carried out the test on the prototype field.Test results show that in tractor travel speed is 1.5m/s,0.5m/s,0.9m/s, measured the fertilizing machine for uniform application of fertilizer coefficient respectively 19.19%, 16.5%,13.0%,the fertilization uniformity is good,can meet the requirements of the standard;The qualified rate of fertilization depth and the breaking rate of fertilizer were 100%, which satisfied the requirement of the standard.
