一种谷物双重比重精选筛A grain double specific gravity screening sieve

技术领域Technical Field

本发明涉及谷物筛选领域，具体属于一种谷物双重比重精选筛。The invention relates to the field of grain screening, and in particular belongs to a grain double specific gravity screening screen.

背景技术Background technique

比重机是一种针对种子进行筛分、选种的机械设备，其可根据种子与杂质物在形状、尺寸、比重、表面特性和空气动力学特性等方面的差异，选出合格优良的种子。同时，还可利用比重机对种子进行精选、分级，选出健壮饱满、生活力强的子粒。从而，比重机替代了传统的人工选种、人工筛分的低效率作业模式。The specific gravity machine is a mechanical device for screening and selecting seeds. It can select qualified and high-quality seeds based on the differences between seeds and impurities in shape, size, specific gravity, surface characteristics and aerodynamic characteristics. At the same time, the specific gravity machine can also be used to select and grade seeds to select strong, plump and vigorous grains. Therefore, the specific gravity machine replaces the traditional inefficient operation mode of manual seed selection and manual screening.

但现有的比重机，在筛分、选种时，由于其内部的筛分装置需往复运动，从而带动比重机发生一定的晃动。因此，比重机使用一定时间以后稳固性较差，进而出现种子掉落等问题。However, the existing specific gravity machine has a certain shaking when screening and selecting seeds because the screening device inside it needs to move back and forth. Therefore, the specific gravity machine has poor stability after being used for a certain period of time, and then problems such as seeds falling occur.

本发明的比重筛是利用杂质与谷物的重量和悬浮速度不同的物性借助向上穿过谷物渣间隙的气流作用促使杂质与谷物分级，在作定向倾斜往复运动的提杂筛板作用下，向出杂口流动，从而把杂质从谷物中分离出来。双重比重筛是在原单个比重筛基础上增加高频振动筛作为过度方式，使谷物在进行一次比重筛选后经振动筛筛选分级，再二次比重筛选残余霉变、除尘，增加筛选效果，提高谷物筛选精度，同时又做到环保无污染的效果。The specific gravity screen of the present invention utilizes the different physical properties of weight and suspension speed of impurities and grains to promote the classification of impurities and grains by means of the airflow passing upward through the gap between grain residues. Under the action of the impurity-lifting screen plate that performs directional inclined reciprocating motion, the impurities flow toward the impurity outlet, thereby separating the impurities from the grains. The double specific gravity screen is based on the original single specific gravity screen and adds a high-frequency vibrating screen as a transition method, so that the grains are screened and graded by the vibrating screen after a specific gravity screening, and then the residual mildew and dust are removed by a second specific gravity screening, thereby increasing the screening effect and improving the grain screening accuracy, while achieving environmental protection and pollution-free effects.
