Grassland Rodent Bait Spray Machine Suspension Breakage Reason And Improvement

The prairie area of our country is vast, in recent years large area rodent occurs, and it impacts on the ecological environment and sustainable development seriously, so demand on the grassland rodent and the gradual increases.Urgent we need to develop efficient ground spraying machinery that can be highly efficient. In this thesis, Inner Mongolia Agricultural University developed grassland rodent bait spray machine as the basis, the last two years of the equipment in the Xilin Gol Grassland gray Teng beam state-operated grass rodent homework problems based on the measured data, combined with the three point suspension bracket of in-depth research and improvement, in order to solve three point hanging in application in the production of some of the problems.The terrain of the prairie is complex and changeful, In order to improve the performance of the grassland rodent bait spray machine, operation mode is improved into a tractor backpack, and it has validated. In this paper, the use of Heilongjiang Academy of agricultural machinery engineering science production field and mechanical dynamics parameter telemetering instrument on the bait spraying machine in the grassland rodent homework three point suspension rack rod, on the left, right suspension bracket for instantaneous dynamics data acquisition, and Excel chart by analysis; the use of new electrical method of hanging bait spraying machine weight and center of gravity position:simply measured left, right two hanging pin of the vertical force and horizontal force, then measure the related angles and bait spray machine position dimension, through calculating the weight and centre of gravity position; using Pro/E software to establish the three point suspension bracket of three-dimensional model and equivalent particle model; through the ANSYS software on the equipment of three point suspension bracket for static analysis of structure, the maximum stress, strain of the danger zone data information for bait, spraying machine is improved to provide a theoretical basis for design.
