Problems solved by technology

In recent years, the research results of rice direct seeding machinery are mostly completed by special seeders. The seeders specially developed for rice direct seeding are used to implement rice direct seeding. The sowing effect is very ideal, but they also have the defects of single function and high purchase cost.

Embodiment Construction

[0011] specific implementation plan

[0012] A fixed plate (11) is obliquely arranged in the opener (8) of the conventional rotary drill machine, and the fixed plate (11) clamps the seeding pipe (5) of the outer groove wheel type seeder on a in a fixed position. The opening and closing plate (7) is arranged directly below the seed pipe (5), and it is fixedly connected with the sowing opening and closing shaft (9), and the sowing opening and closing shaft (9) is hinged on the traveler (8). One end of the sowing opening and closing shaft connecting plate (6) is fixedly connected with the sowing opening and closing shaft (9), and the other end is connected with the return spring (4).

[0013] The ratchet (1) is fixed on the seeding shaft (13) of the outer grooved wheel type seeder by a stop screw (12). The connecting guide rod (3) is interspersed on the fixed frame (2), and one end of the connecting guide rod (3) bears against the ratchet of the ratchet (1), and the other end a...

Abstract

The present invention provides a kind of clearance-type seeding mechanism matched with outer groove-wheel sowing machine. It is characterized by that it can make the traditional mode of sowing in line be changed into the mode of sowing in hole, and drive mechanism at least includes the following several portions: ratchet wheel, connecting guide rod and reset spring. Said invention also provides the concrete operation method of said intermittent seeding mechanism.

Description

Technical field [0001] The invention relates to agricultural machinery, in particular to a mechanism for changing the outer grooved wheel seeder from row sowing to hole sowing, which is used in conjunction with the outer grooved wheel type seeder. Background technique [0002] Mechanized direct seeding of rice is an important scientific research topic in the agricultural machinery industry in recent years. According to the growth characteristics of rice, ensuring the seedling spacing during seedling growth is the key. Therefore, rice direct seeding machinery must be designed for hole sowing according to the agronomic requirements of rice growth. In recent years, the research results of rice direct seeding machinery are mostly completed with special seeders. The seeders specially developed for rice direct seeding are used to implement rice direct seeding. The sowing effect is very ideal, but they also have the defects of single function and high purchase cost. The external gr...
