The Whole Machine Design And Experiment Research Of Single Row Ridge Planting Oblique Cutting Cassava Planter

The current cassava planting form is basically artificial planting,and some of the existing cassava planting machines are also large-scale planting machines on the farm.Because of their high cost,they are not suitable for farmers on small plots in the south.Based on the above reasons,this article proposes to design a single-row ridge-growing diagonal cassava planter suitable for farming in small plots of southern China.The main research contents are as follows:According to the cassava planting agronomy and the structural requirements of the planting organization,the overall plan of the semi-automatic cassava planting machine with single row ridge cultivation and diagonal insertion is designed.The overall structure and working principle of the single-row ridge cultivation oblique insertion four-claw clamping cassava planter are designed in detail.Combining ridge cultivation,oblique insertion and single-row mode to design the four-claw clamping mechanism and transmission system of the single-row oblique insertion cassava planter.Field investigation on the agronomy of cassava planting and understanding of the 60° oblique planting pattern of cassava cutting patterns of all cassava cutting patterns have the highest yield of cassava.The designed single-row ridge cultivation type oblique insertion cassava planter has a seed spacing of 800 mm and a row spacing of 800 mm.The planting depth of cassava seeds should be greater than 90 mm.With the goal of high survival rate and accurate cassava oblique insertion,it is proposed to design a suitable Single-row ridge-type oblique inserting cassava planter for farmers in small plots in the south.The structural model and mathematical model of the planting mechanism of the single-row ridge-growing oblique-inserting cassava planter is established,and the motion law of the four-jaw clamping planting mechanism of the cassava planter is analyzed based on ADAMS software technology,and the motion trajectory model is analyzed.The Ansys modal analysis was performed on the frame of the cassava planter.Through the modal analysis method,the rationality and stability of the designed frame was determined,and the frame of the single-row ridge planting diagonally inserted cassava planter was guaranteed to be in good condition.Stable performance during field work.Through the production of prototypes and field trials of the prototypes in the Danzhou campus of Hainan University,field tests were conducted on the performance of the prototypes in actual field operations;the test results show that the designed single-row ridge-type oblique planting cassava planter The actual planting effect is that the missed seed rate of cassava seeds is less than 7%,the pass rate of oblique planting with an inclination of 60°±5° is higher than 80%,and the survival rate of cassava seeds is greater than 80%.The results show that the designed single-row ridge cultivation type is oblique.The rationality and feasibility of the prototype of the cassava planter;the prototype of the single-row ridge-growing oblique cassava planter and the traditional seedling tube cassava planter were compared and studied.The test results show that the planting performance and planting accuracy of the single-row ridgegrowing oblique-insertion cassava planter designed in this paper are higher than that of the traditional seedling tube planter.
