具体地，所述称重装置4包括称重托盘41，为了保证加料桶1与称重托盘41之间的稳定性，所述称重托盘41上设置有与所述出料口13匹配的承载架42，所述加料桶1的桶体12卡在所述承载架42，使所述加料桶1的全部重量落在承载架42上，保证重量测量的准确性，所述承载架42内设置有称重传感器，同时所述称重托盘41的底部设置有支撑杆43，所述支撑杆43固定在地面上，保证承载架42的支撑稳定。Specifically, the
具体地，所述振动装置3包括调频振动电机31和振动圈32，所述调频振动电机31设置在所述振动圈32上，所述振动圈32套设在所述筛料盘2的外侧，且所述振动圈32与所述加料桶1之间留有振动间隙，在保证筛料盘2振动的同时，能够防止振动传递到加料桶1上，保证称重装置4测量的加料桶1的重量稳定。Specifically, the
参照图2所示，所述运输装置5包括机架51、主动轮52、驱动装置、从动轮53、皮带54，所述驱动装置与主动轮52连接，所述皮带54套设在主动轮52和从动轮53的外侧，驱动装置带动主动轮52转动，从而带动皮带54在主动轮52和从动轮53上运行，所述皮带54设置在所述筛料盘2的下方，所述皮带54的宽度大于所述出料口13的宽度，使从出料口13落下的物料全部落在皮带54上。Referring to FIG. 2 , the
优选地，为了进一步防止物料从皮带54上落下，在所述皮带54上设置有向下凹陷的料槽，所述料槽的宽度大于所述出料口13的宽度，使从出料口13落下的物料全部落在皮带54的料槽中。Preferably, in order to further prevent the material from falling from the
本实施例中，由于运输的物料为粒状物料和粉状物料，在运输的过程中，容易受到运输环境的影响，一方面会造成运输环境的污染，大量粉尘、颗粒漂浮在空气中，另一方面在运输时洒落或被风吹走，也会造成给料量的减少。所以本实施例中，在所述运输装置5外设置有防尘罩6，所述防尘罩6为封闭的箱体，所述防尘罩6的上方开设有与所述加料桶1连通的进料通道61，所述防尘罩6下方设置有出料通道62，所述出料通道62设置在所述运输装置5的输送端，通过设置防尘罩6使运输的过程在密闭的空间内完成。In this embodiment, since the materials to be transported are granular materials and powdery materials, they are easily affected by the transportation environment during the transportation process. On the one hand, the transportation environment will be polluted, and a large amount of dust and particles will float in the air. On the other hand, it is scattered or blown away by the wind during transportation, which will also cause a reduction in the amount of feed. Therefore, in this embodiment, a dust cover 6 is provided outside the
具体地，由于筛料盘2的中的漏料孔的数量和孔径有限，当频率达到一定后，漏料孔中的漏料量达到最大值，即使进一步增加振动装置3的振动频率也无法使下料量增加，此时如果下料量仍达不到定量给料的要求时，就需要设置辅助供料装置，所述辅助供料装置进料口7设置在所述进料通道61的侧面，所述辅助供料装置上同样设置有振动供料装置、称重装置4，也可以调节辅助供料装置的给料量。Specifically, due to the limited number and diameter of the leakage holes in the
