Description

一种农用筛选机构
技术领域
本发明涉及农用器械技术领域，具体为一种农用筛选机构。
背景技术
农业的种植、粮食收获后的处理及农产品加工中都要用到筛选机构，一般种植的种子和收获的粮食内会含有较轻的粉尘杂质和颗粒杂质，在种子种植或粮食谷物储存加工前都需要先清除杂质，现有技术多是采用单独的一种筛选结构，筛选的原料堆积在一起不易筛选操作，需要来回返工，加大了劳动强度，工作效率低。
发明内容
(一)解决的技术问题
针对现有技术的不足，本发明提供了一种农用筛选机构，解决了筛选不充分不均匀的问题。
(二)技术方案
为实现以上目的，本发明通过以下技术方案予以实现：
一种农用筛选机构，包括有机架，其特征在于：所述机架上安装有顶部敞口的罩壳，罩壳底部呈漏斗形结构，所述的罩壳内设有转动安装的筛筒，筛筒上设有带盖的入料口，在机架上顶部设有下料斗，下料斗底面设有下料口，所述下料斗内有竖直隔板将下料斗内腔分为左、右两部分，所述的下料口与下料斗左、右两部分都连通，所述下料斗左、右两部分的内壁上分别设有电热丝；下料斗底面下料口上连通有下料管，下料管的管口正对着罩壳内筛筒的入料口；所述机架上在罩壳的后方固定有立杆，立杆顶部铰接连接有支撑杆，支撑杆上安装有击打块，所述的击打块正好击打在筛筒的筒壁上；所述罩壳下方设有一筛箱，罩壳底面设有料口对着筛箱内，所述的机架上两端分别铰接安装有悬臂，所述的筛箱与悬臂铰接连接，筛箱一侧设有气缸，气缸的活塞杆上铰接连接有连接杆，连接杆的另一端与所述的筛箱铰接连接，气缸活塞杆上下伸缩推动筛箱左右来回摆动，所述筛箱内设有一层筛板，在筛板的下方设有一倾斜的导料板，所述筛箱的侧壁上对应导料板的位置设有出料口；在筛箱出料口的下方设有一除尘箱，除尘箱与一震动器连接，除尘箱底面采用筛网结构，所述的除尘箱内壁上设有多个倾斜挡料板，除尘箱一侧设有吸风机，吸风机的吸风管伸入到除尘箱内吸出尘屑。
优选的，所述吸风机的吸风管上连接有两个分支吸风管，两个分支吸风管分别伸入到罩壳内和筛选内吸尘。。
优选的，所述倾斜挡料板的板面上设有小凸起。
优选的，所述下料斗底面下料口上连通的下料管内设有挡料杆。
(三)有益效果
本发明提供了一种农用筛选机构，具备以下有益效果：
本发明筛选机构采用多重的筛选结构，首先在筛筒内随着筛筒转动筛选，再进入到来回摆动的筛箱内，最后进入除尘箱内再次震动筛选，且具有吸尘的作用，筛选原料不会堆积在一起，筛选充分；另外本发明的原料进入下料斗内，下料斗内有加热丝，能对原料进行初步干燥，去除表面水分更容易筛选操作。
