The invention discloses a tractor rear suspension hooking device of a grass holding clamp machine tool, and belongs to the technical field of agricultural mechanical equipment. The tractor rear suspension hooking device comprises a support, a limiting groove matched with the support is formed in the top of an upper supporting leg, a sliding rod is slidably arranged in the limiting groove, and mounting plates are welded to the top and the bottom of the limiting rod; the mounting plates are fixed to the top of the support through screws, the outer wall of the limiting rod is sleeved with a sleeve, the top and the bottom of the joint of the outer wall of the limiting rod and the sleeve are sleeved with torsion springs; when the tractor runs on a bumpy road section, the sleeve slides on the outer wall of the limiting rod, and the impact force of bumping of the tractor on the linkage rod is reduced. And under the action of a torsion spring and a supporting spring, the acting force of up-down shaking is weakened, in the up-down shaking process, a piston plate and a rod piece slide left and right in a connecting shell, a first spring and the torsion spring are used in cooperation, and theimpact force of up-down shaking is further buffered.

    本发明公开了农用机械设备技术领域的一种抱草夹机具的拖拉机后悬挂挂接装置,包括支架,所述上支腿顶部开设有与支架相配合的限位槽,所述限位槽内滑动设有滑动杆,所述限位杆的顶部和底部均焊接有安装板,所述安装板通过螺丝固定在支架顶部,所述限位杆外壁套设有套管,所述限位杆外壁与套管连接处的顶部和底部均套设有扭力弹簧,在拖拉机行驶在颠簸路段时,套管在限位杆外壁滑动,减小拖拉机颠簸弯给联动杆带来的冲击力,而在扭力弹簧和支撑弹簧的作用下,对上下抖动的作用力进行削弱,在上下抖动的过程中,活塞板与杆件在连接壳内左右滑动,而第一弹簧与扭力弹簧配合使用,进一步对上下抖动的冲击力进行缓冲。
