Self-sucking and self-discharging screening sand dredger
The invention relates to a self-sucking and self-discharging screening sand dredger which comprises a motor (13) and a screening device (7). The screening device (7) comprises a first-stage sand diameter recovery cavity (21), a second-stage sand diameter recovery cavity (26), a third-stage sand diameter recovery cavity (31), a fourth-stage sand diameter recovery cavity (22) and a fifth-stage sand diameter recovery cavity (24); and the screening device (7) is driven by the motor (13) to rotate and centrifugally move around a sand inlet pipeline (38) through three groups of bearings (23). According to the self-suction and self-discharging screening sand dredger, a five-stage screening structure is adopted, sand grains with different sand diameter grades are screened out, coarse sand and fine sand can be effectively utilized, and therefore sand resource waste caused by the fact that the coarse sand and the fine sand are not separated can be reduced.
本申请涉及一种自吸自卸筛分采沙船，包括电机(13)和筛分器(7)；筛分器(7)包括一级沙径回收腔(21)、二级沙径回收腔(26)、三级沙径回收腔(31)、四级沙径回收腔(22)和五级沙径回收腔(24)；筛分器(7)通过三组轴承(23)在电机(13)的驱动下绕进沙管道(38)做旋转离心运动。该自吸自卸筛分采沙船采用五级筛分结构，将不同沙径等级的沙粒分别筛选出来，能够使粗沙、细沙得到有效的利用，如此，可以减少因粗、细沙不分而造成的沙资源浪费。
