Description

Secondary crushing belt rotary tiller

technical field

The invention relates to the field of agricultural machinery, in particular to a belt-shaped rotary tiller for secondary crushing.

Background technique

Conservation tillage has the functions of water conservation, soil and fertilizer conservation, cost saving and efficiency enhancement. Now my country, especially in the north, has been promoted to a certain extent, and has created certain economic and social benefits. It is the key to realizing sustainable agricultural development. one of the effective ways. However, the development of the flood-drought continuous cropping area in the south is relatively slow. In addition to natural factors, the lack of matching no-tillage seeders is a very key reason.

At present, most of the no-tillage seeders are suitable for the farming mode in the north. For example, the Chinese patent application number is 200920175499.4, and the utility model patent named "Wheat No-tillage Seeder" introduces related technologies for cutting stubble and grass, but It is not suitable for operation in the sticky and heavy soil and rice stubble field with high water content in the south. When sowing wheat in the rice-wheat continuous cropping area in the south, in order to create a suitable seedbed for the seeds, two operations are often used to meet the requirements of thicker soil and finer soil. The Chinese patent application number is 201010621604.x, and the name is " The invention of the No-tillage Wheat Seeder for Rice Stubble Fields uses the "Y" blade to solve the problem of sticking straw and weeds. The utility model patent of "integrated mechanism" focuses on solving the problems of ditching and stubble removal, but it does not mention how to ensure the passability of the no-tillage planter while reducing the rotation under the premise of meeting the sowing requirements. The number of times the tiller goes to the ground and reduces energy consumption. For this reason, it is very necessary to develop a kind of no-tillage planter suitable for southern sticky and heavy soil.
