Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of no-tillage machine structures, in particular to an automatic ridge spacing adjustment device used for a no-tillage machine. Background Art
[0002] No-till seeder is a machine that uses machinery to replace the original manual sowing, fertilization, and tillage steps, and completes them in one step. It is specifically used in economic crops such as corn, soybeans, potatoes, and garlic that are suitable for large-scale planting. No-till seeders mainly include corn seeders, soybean seeders, garlic seeders, potato seeders and other machines. They are mainly used to solve the problems of insufficient labor and labor costs in rural areas, and to expand agricultural planting areas and mechanization levels.
[0003] There are generally two types of connection relationships between the no-tillage units and the main beam of the existing no-tillage machines. One is to directly weld and fix the no-tillage units to the main beam after determining the distance between adjacent no-tillage units, i.e., the ridge distance; the other is to provide a width adjustment sleeve at the front end of the no-tillage unit, which is set on the main beam through the width adjustment sleeve, and the width adjustment sleeve can move horizontally on the main beam. However, there are some problems with both of these connection methods. The first fixed connection method cannot adjust the ridge distance, and its scope of application is limited; although the second connection method can adjust the distance between the no-tillage units, due to the large weight of the no-tillage units, each adjustment requires multiple people to lift and move the no-tillage units together, which makes the adjustment difficult and it is impossible for one person to complete the adjustment of the ridge distance alone. In addition, the error of each adjustment is large, and it cannot be guaranteed to be adjusted to the appropriate position at one time, which wastes time and manpower and is inefficient.
