一种双重仿形播种覆膜机架
摘要：
本发明公开了一种双重仿形播种覆膜机架，包括悬挂机架、播种覆膜机架和膜上覆土滚筒支架。悬挂机架一端连接有拖拉机，另一端通过成对设置的第一连杆与播种覆膜机架相连，悬挂机架、第一连杆和播种覆膜机架组成第一四连杆仿形机构。播种覆膜机架通过一对第二连杆与镇压机构相连，播种覆膜机架、第二连杆和镇压机构组成第二四连杆仿形机构。镇压机构上安装有仿形轮、排种器和播种开沟器。膜上覆土滚筒支架一端与播种覆膜机架相连，另一端连接有滚筒。播种覆膜机架上设置有地膜支架和展膜拉杆连接座，展膜拉杆连接座上设置有展膜辊。本发明提供的双重仿形播种覆膜机架能够同时进行仿形播种和仿形覆膜作业，既提高了播深一致性，又能平整覆膜。
摘要（英）：

The invention discloses a dual-profiling sowing and mulching frame. The dual-profiling sowing and mulching frame comprises a suspension frame, a sowing and mulching frame, and a mulch earthing rollerbracket. One end of the suspension frame is connected with a tractor while the other end is connected with the sowing and mulching frame through first connecting rods arranged in pairs, and the suspension frame, the first connecting rods, and the sowing and mulching frame constitute a first four-rod linkage profiling mechanism. The sowing and mulching frame is connected with a suppression mechanism through a pair of second connecting rods, and the sowing and mulching frame, the second connecting rods, and the suppression mechanism constitute a second four-rod linkage profiling mechanism. The suppression mechanism comprises a profiling wheel, a seed arranging device and a sowing opener. One end of the mulch earthing roller bracket is connected with the sowing and mulching frame while the other end is connected with a roller. The sowing and mulching frame is provided with a mulch bracket and a film spreading pull rod connecting base, and a film dual-profiling sowing and mulching frame can simultaneously perform profiling sowing and mulching operations, which not only improves the consistency of sowing depth, but also achieves flat mulch.
