Description

Technical Field

[0001] The utility model relates to a turning and pressing mechanism for returning Chinese astragalus to the field, belonging to the technical field of returning Chinese astragalus to the field. Background Art

[0002] Chinese milk vetch, also known as red flower grass, is a biennial herbaceous plant of the Leguminosae family and the genus Astragalus. Chinese milk vetch is a biennial herbaceous plant of the Leguminosae family. It is cultivated in many parts of China and is an important green manure crop and livestock feed. The tender shoots can also be used as vegetables. After it is used as green manure, the land needs to be directly turned over to cover the Chinese milk vetch and let it rot in the soil;

[0003] For example, a turning and pressing device for returning astragalus to the field with patent publication number CN202022457883.2 includes a main board, side boards, push-pull rods, a turning mechanism and a flattening mechanism. Push-pull rods extending obliquely upward are provided at both corners of one side of the main board, and side boards extending obliquely downward are provided at both corners of the other side. A turning mechanism is installed between the two side boards, and a flattening mechanism is installed at the lower end of the main board. The turning mechanism includes a main shaft, a main gear, a turning motor, a transmission chain, a turning tooth, a transmission shaft and a moving wheel. The main board is rotatably connected with a main shaft, and the main shaft is connected to the turning motor.

[0004] Since the above-mentioned turning device performs soil turning operations by pushing the turning structure, the operating force of the double-sided raised soil blocks is limited, which makes it difficult to perform quick and powerful soil turning operations on harder ground, indirectly reducing the efficiency of returning Chinese milk vetch to the field and bringing certain adverse effects to actual use, so it needs to be improved.
