一种脱粒滚筒制造技术
A threshing roller
The invention relates to a threshing device, in particular to a threshing cylinder, including threshing components, supporting rod and the threshing spindle, supporting rod fixed at both ends of the spindle on the convex threshing threshing components, axial mounted between the two support rod, which is characterized in that the support rod axial installation screen plate the screen plate is made of wire, and the mounting plate, the mounting plate on the circumference uniformly distributed arc welding wire between the adjacent mounting plate; the beneficial effect of the invention is a screen plate, to be part of grain threshing exert the crackdown, and to stop the grain, grain by not threshing threshing elements blow several times in the reticular plate, so as to make the threshing more fully; two is due to structural support of the mounting rod is adjustable, and can change the screen plate to adjust the different types of screen plate The size of the gap is used to separate the threshing and non threshing materials to achieve a preliminary cleaning effect; three is to disassemble.

一种脱粒滚筒
本专利技术涉及一种脱粒装置领域，特别是一种脱粒滚筒。
技术介绍
传统的脱粒装置分为单滚筒和多滚筒脱粒装置，单滚筒脱粒装置的结构相对于多滚筒装置的结构较为简便，功耗相对于较小，单滚筒主要有以下几种形式：一、钉齿型滚筒，钉齿滚筒脱粒时主要靠钉齿正面冲击谷物使其脱粒，工作过程中揉搓作用相对较弱；这种脱粒结构的特点是对难脱的和比较潮湿的作物适应性好；二、纹杆式滚筒，滚筒工作时靠纹杆对作物的多次打击和纹杆与凹板表面产生的揉搓作用使作物籽粒脱落。这种脱粒装置的特点是具有较好的脱粒、分离性能，茎秆断碎较少，对油菜作物有较好的适应性；三、纹杆一钉齿复合式滚筒，其工作用原理为脱粒滚筒在旋转时利用纹杆与凹板筛对油菜角果荚揉，搓，擦，使油菜籽与角荚分离脱下。滚筒旋转时，角果莱及碎茎秆在导向板及纹耔作用下推向脱粒滚筒后端钉杆齿上，然后通过旋转杆齿进一步对其冲击摔打，从而使油菜籽粒脱下。多滚筒主要为多个单滚筒组合成一组脱粒装置，相对于单滚筒装置有更好的脱粒效果，脱净率可显著提高，但相对于单滚筒的功耗也相对增加，体积结构也更为复杂。此外传统脱粒是先脱粒再通过单独的筛网或振动板进...
