具体实施方式Detailed ways
为了便于本领域技术人员理解,现将实施例结合附图对本实用新型的结构作进一步详细描述:In order to facilitate the understanding of those skilled in the art, the structure of the present utility model will be further described in detail with reference to the accompanying drawings:
参考图1-2,一种土建用沙土过筛装置,包括由机架支撑设置的匀料机构1和筛分机构2,所述匀料机构1包含倾斜设置在机架3上方的匀料板4,所述匀料板4中间位置铰接安装在机架3上且由驱动机构5左右反复驱动设置;所述驱动机构5包含铰接匀料板4的连动杆6,所述连动杆6连接到由电动机7和减速电机8驱动的转盘轮9;所述筛分机构2是由倾斜设置的第一筛板10和第二筛板11形成八字形结构,所述第一筛板10和第二筛板11的下方设置有集料槽12;所述匀料板4的出料口下方与其同向倾斜设置所述第一筛板10,所述第一筛板10进料口下方与其反向倾斜设置所述第二筛板11;所述第一筛板10上方设置有推料机构,所述推料机构包含由驱动气缸13连接驱动设置的推料板14;所述推料板14与所述第一筛板10的筛网垂直且按间隔设置;第二筛板11连接有振动电机15;所述第一筛板10和第二筛板11均由相同孔径大小的筛网和框架(未标识)构成,所述第一筛板10的框架两侧设置有挡板12。1-2, a sand screening device for civil construction includes a screed mechanism 1 and a screening mechanism 2 supported by a frame, and the screed mechanism 1 includes a screed plate inclined above the rack 3 4. The middle position of the screed plate 4 is hingedly installed on the frame 3 and is repeatedly driven left and right by the
由于电动机7驱动转盘轮9转动并带动匀料板4以其铰接安装点中间点左右反复移动以及匀料板4倾斜设置,放置在上的物料会有一个向下滑动的作用力。因而沙土通过绞龙机构将沙土传送至匀料板4上后,沙土会在匀料板4上连续较为均匀批量的沿着匀料板4导料至筛分机构2内,从而避免沙土成堆进料。且通过匀料板4和筛分机构2之间的间隔设置使得连续成批均匀进料的同时采用高度差使得成批的沙土分散开,避免潮湿粘黏,利于后续过筛。沙土传送到第一筛板10上由于第一筛板10的倾斜设置,沙土会滑落至第一筛板10倾斜向下的一端,再用推料板14推动沙土促进其部分颗粒较小的沙土通过第一筛板10的筛网;其余沙土会经推料板14的推动传送至第二筛板11,再通过第二筛板11和振动电机15驱动进行振荡过筛。连续成批均匀进料和二次过筛可避免沙土堆积,进而促进均匀过筛,提高过筛效果。Since the motor 7 drives the
