本发明公开了一种机身高度调节装置及摊铺机，包括第一驱动件、滑块、滑块座、第二驱动件、限位件、铰接座、铰接轴、滑动杆、安装座，滑块座固定设置在机身上，滑块座中部开设供滑块滑动的滑槽，滑块座侧部设置多个限位孔，滑块侧部设置配合孔；滑块底端嵌入滑槽，滑块顶端固定在行走装置上；第一驱动件的一端固定在机身侧部，另一端连接滑块中部；第二驱动件的一端与机身连接，另一端连接限位件，第二驱动件驱动限位件依次穿过限位孔和配合孔；铰接座固定在行走装置前端，安装座固定在机身上，安装座内部设有供滑动杆嵌设的凹槽，滑动杆一端通过铰接轴与铰接座铰接，另一端滑动地设置于凹槽内。本发明的摊铺机机身高度可调节，通用性更强。

The machine body height adjusting device comprises a first driving piece, a sliding block, a sliding block seat, a second driving piece, a limiting piece, a hinge seat, a hinge shaft, a sliding rod and a mounting seat, the sliding block seat is fixedly arranged on a machine body, a sliding groove allowing the sliding block to slide is formed in the middle of the sliding block seat, a plurality of limiting holes are formed in the side portion of the sliding block seat, and a matching hole is formed in the side portion of the sliding block; the bottom ends of the sliding blocks are embedded into the sliding grooves, and the top ends of the sliding blocks are fixed to the walking device. The other end of the first driving piece is connected with the middle part of the sliding block; one end of the second driving piece is connected with the machine body, the other end is connected with the limiting piece, and the second driving piece drives the limiting piece to sequentially penetrate through the limiting hole and the matching hole; the hinge seat is fixed at the front end of the walking device, the mounting seat is fixed on the machine body, a groove allowing the sliding rod to be embedded is formed in the mounting seat, one end of the sliding rod is hinged to the hinge seat through a hinge shaft, and the other end of the sliding rod is slidably arranged in the groove. The paver provided by the invention has the advantages of adjustable height of the paver body and higher universality.
