Test-bed of the 2BST-160 cron sower function

This paper introduced the general design,mount analysis of the main work and the experimental results of the test-bed of the 2BST-160 sower functions. It adopted belt-movement system, automatic fuel injection & spatula system, universal installation machine and the seeds space examining system based on the technology of imaging processing and analyzing. This test-bed can complete the experiences of precision, corn sower and sower unit, seeding uniformity of precision-meter, which owns the abilities of accuracy, reliably, visualization, and easily tracing to the source of seeding-space. Auto-controlled by hydraulic pressure and by means of cross shaft, the test-bed can lean 11° in four directions and simulate the slope planting through adjustment of its height. Each operation machine of the mount was controlled by the computer and the PLC system in real-time, in this way, the test-bed can control automatically the experiments of sower functions. Meanwhile, the test-bed can also be operated manually.
