基于粒料在移行中可自动产生间距的转盘斜刮排序原理,设计了转盘斜刮式光电自动数粒仪和千粒重仪。无序的粒料或种粒进入有斜槽和弧槽的槽盘中,在底部转盘带动下实现移行、自动整齐排序和产生粒间距,获得光电计数所需的可靠透光间隙,并通过预置和复检二次计数实施数粒。试验表明:每轮预置计数误差数小于1～2颗,而复检计数与实际粒数的误差率小于0.04%;计数速度可达30～50粒/s;粒料适用范围为0.5～18 mm;未发现供试粒料破损现象;结构简单可靠,无电磁振动噪声等;转盘斜刮式排序原理还可用于开发高精度无粒料损伤的数粒设备。
Based on the principle of inclined scraping of the turntable which can generate the pitch automatically during the migration of the pellet, the rotary tilting scraping optoelectronic automatical granulometer and the thousand gravimeter are designed. Disordered pellets or seeds enter the grooved tray with chute and arc groove, which can be moved under the bottom turntable to automatically align and produce grain spacing to obtain the reliable light transmission gap needed for photoelectric counting, Set and re-count the second count implementation of a few tablets. The results show that the number of presetting errors per round is less than 1 ~ 2, while the error rate between the retest count and the actual number of particles is less than 0.04%; the counting speed can reach 30 ~ 50 / s; mm; No damage to the test pellets was found; the structure is simple and reliable, and no electromagnetic vibration noise and the like; the principle of scraping the scraper of the turntable can also be used to develop a few grains of high-precision pellet-free equipment.
