小区精密播种机试验台系统设计与试验

摘要

Considering such restrictions for agricultural field trials as location , season , equipment and other factors which result in long test cycle , low accuracy and high cost , a precision plot seeder test bench system was presented .The test bench system , including two parts of the electrical and mechanical , could simulate the seeder walking in the laboratory and complete seeding experiments under a variety of conditions .After many times of tests , the test bench system can bet-ter accomplish the performance tests of the precision plot seeder , which has a great significance in improving electrical control performance , increasing their digitization , electrification , accuracy and lowering the cost of test trials for the pre-cision plot seeder .%针对目前农机田间试验易受地点、季节以及设备等因素的限制，造成试验周期长、准确度低、费用高等诸多问题，提出了一种小区精密播种机试验台系统。该试验台系统包括电气和机械两大部分，可在实验室内模拟播种机行走，并完成多种情况下的排种试验。多次试验结果表明，该试验台系统可以较好地完成小区精密播种机性能测试，对于改善小区精密播种机的电控性能、提高其数字化和电气化精密程度、降低试验测试成本具有重要意义。
