本文介绍一种莴苣播种机的设计、制造和试验。这种播种机用一台微处理器作为主控制器,对象莴苣这样的形状不规则的小粒种子,进行单粒播种。在涂黄油的胶带上进行的实验室试验表明,用微处理器控制的播种机播种未包衣的莴苣种子,其播种精度比约翰·迪尔33型蔬菜播种机(市场上销售的机型)高。 This article describes the design, manufacture, and testing of a lettuce seeder. This planter uses a microprocessor as the main controller, the object lettuce, such as the irregular shape of small seeds, sowing. Laboratory tests conducted on butter tape show that uncoated lettuce seeds are seeded on a microprocessor controlled seeder at a sowing accuracy better than the John Deere Model 33 Vegetable Sowing Machine (a commercially available model) high.
