The invention discloses a receiving lifting-falling mechanism for a material pushing trolley. The receiving lifting-falling mechanism comprises a main frame body, vertical screws are arranged on the left side and the right side of the main frame body correspondingly, the bottom ends of the two vertical screws are hinged to a main bottom plate of the main frame body through bearings, the top ends of the two vertical screws are hinged to an upper top plate of the main frame body through bearings, two lifting-falling motors are fixed to the top surface of the upper top plate, and the lifting-falling motors drive the corresponding vertical screws to rotate; and lifting blocks are in threaded connection with the interiors of the two vertical screws, a material receiving frame is fixed to the front wall surfaces of the lifting blocks, a plurality of rolling sliding grooves are formed in the top surface of a bottom plate of the material receiving frame, limiting holes are formed in the bottomsurfaces of the front ends of the rolling sliding grooves, limiting columns and buffer springs are inserted into the limiting holes, the top ends of the buffer springs are applied to the limiting columns, and the upper ends of the limiting columns extend out of the top surfaces of the rolling sliding grooves. According to the receiving lifting-falling mechanism of the material pushing trolley, anoverhauling groove is formed in the lower part of a vertical main cylinder body, an overhauling door body of the overhauling groove can automatically lift to be opened and fall to be closed, and thusmaterials in the vertical main cylinder body are conveniently cleared.
本发明公开了一种推料车接收升降机构,包括主架体,所述主架体的左右两侧均设有竖直螺杆,两个竖直螺杆的底端通过轴承铰接在主架体的主底板上,两个竖直螺杆的顶端通过轴承铰接在主架体的上顶板上,上顶板的顶面固定有两个升降电机,升降电机带动对应的竖直螺杆转动,提升块螺接在两个竖直螺杆中,提升块的前壁面上固定有接料架,接料架的底板的顶面成型有多个滚动滑槽,滚动滑槽的前端的底面成型有限位孔,限位孔中插套有限位柱和缓冲弹簧,缓冲弹簧的顶端着力于限位柱,限位柱的上端伸出滚动滑槽的顶面。本发明可以在竖直主筒体的下部设有检修槽,其检修门体可以自动提升开启和下降关闭,从而方便清理竖直主筒体内的物料。
