Small mountain no-tillage seeder

technical field

The invention relates to the technical field of agricultural tillage seeders, in particular to a small no-tillage seeder for mountainous areas.

Background technique

The full-film double-ridge furrow sowing technology plays the role of large-scale moisture conservation and natural flow collection through the full film covering of large and small ridges, so that limited precipitation can be collected through the film surface and enter the sowing ditch to be effectively absorbed by the crops, thus forming a film-collected rainwater collection system. A new cultivation technique for drought resistance and moisture conservation that integrates mulching to suppress steaming and planting in furrows. There are three kinds of commonly used methods at present: (1) hand-held on-demand seeding gun; (2) roller on-demand seeding machine; (3) slotted wheel vertical seeder and cam seeder. The first two are mainly due to low seeding efficiency and high labor intensity, and the roller seeder is prone to film tearing and film picking; the third is that the machine walks on the film, causing damage to the film, high error hole rate, and low seeding efficiency. It has been improved, but it cannot meet the high-efficiency large-area sowing.

The first cylindrical gear meshes with the third cylindrical gear, the installation shaft of the third cylindrical gear is provided with a driving non-circular gear, the driving non-circular gear meshes with the driven non-circular gear, and the driven non-circular gear is installed on the second cylindrical On the gear, the driven non-circular gear is connected with the first crank connecting rod, and the lower end of the second crank connecting rod is connected with the slider of the cavitator, and a cavitator is arranged below the slider of the cavitator, and the cavitator The top is correspondingly provided with a seed guide tube and a cavitation device overhead, and a gear seat is correspondingly installed on one side of the cavitation device.

The power input shaft is connected with external power through a universal coupling, and the power input shaft drives the in-line hole sowing device to drive the socket wheel seeder.

The beneficial effects of the present invention are: the small mountainous no-tillage seeder, which realizes the integration of ridge formation, film covering and sowing, without the carriage on the film to reduce the damage to the film, the row distance is adjustable, the seeding rate is high, and the misplaced holes It has the advantages of low efficiency, centralized ridge forming, film pressing and seeding, and can complete the process in one operation. A new film pressing device is used to make the film compaction more accurate. An improved power transmission method is adopted to speed up the cavitation device. The movement speed and acceleration are continuous, ensuring that the absolute speed of the cavitation device is basically equal to zero at the film entry and exit stages. The optimized film knife angle shape and parameters of the cavitation device are adopted to prevent the seeder from tearing and tearing the film.
