Flexible mounting structure of rotary blade and turning and pressing device

Abstract

The invention discloses a flexible mounting structure of a rotary blade and a turning and pressing device, and belongs to the technical field of agricultural machinery. The flexible mounting structure comprises a flexible mounting tool apron and a flexible buffering structure, one end of the flexible mounting tool apron is provided with a connecting sleeve structure matched with the connecting end of the rotary blade, the other end of the flexible mounting tool apron is provided with an arc-shaped mounting end, a sliding way is formed in the part, close to a connecting sleeve, of the arc-shaped mounting end, and a boss is arranged on the other corresponding side of the arc-shaped mounting end. The arc-shaped mounting end surrounds a rotary blade mounting shaft, the end with the boss is connected to the mounting shaft, and the flexible buffering structure is connected between the boss and the sliding way of the flexible mounting tool apron on the other corresponding rotary blade. A compression spring in the flexible buffering structure is mounted in a compressed mode and can provide certain pre-tightening force, when a machine works in soil with many gravels or encounters green manure with thick and strong root systems, the flexible mounting tool apron is impacted and buffered through the flexible buffering structure, the flexible mounting tool apron is driven by the flexible buffering structure in the advancing working state of the machine, obstacles in the soil can be smoothly crossed, and the rotary blade is not damaged.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a flexible installation structure and an overturning device of a rotary tiller. Background technique [0002] The rotary tillage device is a kind of overturning device that is easy to operate and widely used. In the process of plowing and land preparation, it can achieve the operation effect of stubble removal and crushing soil in one operation, which can effectively loosen the soil and reduce soil compaction. The cut green manure can be crushed and buried. [0003] For plowing and green manure overturning, the working environment is more complex, and there are few adaptable overturning devices, which cannot meet the diversity of the working environment, and when encountering soil with more sand and gravel or green manure with thicker roots, it is easy to Make the rotary cultivator blade of turning over pressure device be deformed or damaged because of...
