The utility model discloses a precision metering device of a crop seeder, which comprises a metering box, a metering wheel, a metering shaft, a star wheel, a star wheel cover, a blocking wheel, a seed baffle plate and an arc bottom tongue. The characteristics of the metering wheel are as follows: the cylinder surface of the metering wheel is distributed with intermittently raised grain-shifting walls, whose lengths may be the same or different, and the adjacent two groups of grain-shifting walls are not in the same axial straight line. One end of the seed metering wheel is equipped with a seed baffle plate, the outer wall of one end of the seed metering wheel is equipped with a blocking wheel, one side of the seed metering box is equipped with a star wheel, the outer side of the star wheel is equipped with a star wheel cover, the lower side of the seed metering wheel is equipped with an elastomer, and the lower side of the elastomer is equipped with an arc bottom tongue. Sowing evenly, sowing quantity is controlled accurately, and the seeds are not broken, so that a small amount of fine seeds can be sown, and a small amount of fine seeds can be sown, so as to realize the mechanized and high-quality operation of small seeds.

农作物播种机精量排种器
本技术属于播种机,具体说是一种农作物播种机精量排种器。
技术介绍
现有的农作物播种机械在工作过程中,因受排种器结构限制,排种过程中有明显的“脉冲性”,而且现有播种机排种器只适合于单一农作物的排种(或排肥),一台播种机不能进行多种农作物的精量排种,播量范围小,也不能精少量排种小粒种子,进行高质量作业,这样便不能适应目前高产高效农业对播种机械的要求。
技术实现思路
本技术的目的在于设计制造一种可满足多种农作物不同播量要求,播量均匀,播量准确控制,可高质量的完成多种农作物不同播量的排种作业,实现精少量排种,实现小粒种机械化精细作业,本技术结构简单,经济实用,是一种新型的农作物播种机精量排种器。为实现上述目的,本技术包括排种盒、排种轮、排种轴、星轮、星轮盖、阻塞轮、挡种板、弹性体和弧形底舌,其特征在于,所述排种轮的外圆柱面上排列有断续凸起的拨粒壁,拨粒壁的长度可相同或者不相同,相邻的两组拨粒壁不在同一轴向直线上,所述排种轮的一端安装有挡种板,所述排种轮的一端外壁上安装有阻塞轮,所述排种盒的一侧安装有星轮,所述星轮的外侧设置有星轮盖,所述排种轮的一侧下方设置有与排种盒内壁连接的弧形底舌,弧形底舌的内弧面设置由毛、丝构成的弹性体。所述拨粒壁沿径向高度方向呈底部圆弧过度的梯形,所述拨粒壁在垂直于轴向的横截面上呈均匀分布状,所述拨粒壁在同一横截面上有6个。所述排种轮圆周上拨粒壁的数量可根据需要进行设置,所述排种轮轴向分布有8组拨粒壁。所述排种轮可由塑料注塑制成。所述挡种板可根据需要安装在排种轮的一端或中间的任意位置,挡种板的数量为0件、1件或多件。所述 ...
