Paddy and fertilizer dual-purpose type seeding rate regulation device

Abstract

The invention relates to a paddy and fertilizer broadcast sowing device, in particular to a seeding rate regulation device capable of being used for rice and fertilizers, and belongs to the field of agricultural machinery. A paddy and fertilizer dual-purpose type seeding rate regulation device is installed between a feed box and a flange of a swing pipe type broadcast sower. The mechanism comprises a material collection mechanism, a regulation mechanism, an auxiliary mechanism, a ratchet wheel stay wire and a quantity control mechanism, wherein the material collection mechanism comprises a connecting part, a material inlet and a material outlet; the regulation mechanism is arranged below the material collection mechanism; the bottom of the auxiliary mechanism is connected and fixed with the flange; the end part of the ratchet wheel stay wire is connected and fixed with the connecting end of the regulation mechanism; the bottom of the quantity control mechanism is fixed on the flange; and the opening of the regulation mechanism and the vertical displacement of the quantity control mechanism are regulated to regulate a rice and fertilizer seeding rate. The paddy and fertilizer dual-purpose type seeding rate regulation device has the beneficial effects that: 1) the seeding rate is regulated in real time; 2) stepless regulation can be realized; 3) materials can effectively preventfrom being hardened and blocked; and 4) a bud damaging rate of the seeding rate regulation device is lowered, and meanwhile, the paddy and fertilizer broadcast sowing device is suitable for the seeding rate regulation of paddy buds and seeds as well as the fertilizers.

Description

technical field [0001] The invention relates to a rice fertilizer spreading device, in particular to a seeding rate regulating device which can be used with rice fertilizer, and belongs to the field of agricultural machinery. Background technique [0002] Rice direct seeding is one of the ways to directly sow rice buds with broken breasts and white buds in the field for rice planting. Compared with transplanting and throwing seedlings, it has the advantages of saving time, labor and seedling field. In recent years, with the improvement of farmland plant protection technology, rice direct seeding technology has developed rapidly, especially in double-cropping rice areas, it can also grasp the farming time in time, which reduces the labor load of farmers, and is widely accepted by farmers. [0003] At present, there are three methods of direct seeding of rice: mechanical hole direct seeding, mechanical drill seeding and manual seeding. The production practice shows that, unde...

AI Technical Summary

Problems solved by technology

Due to the immaturity of mechanized spreading technology, many attempts are made to use fertilizer spreaders instead. However, due to the tenderness of rice buds and poor fluidity, the gate-type seeding rate adjustment mechanism of the fertilizer spreader is prone to severe crushing by the agitator during operation. The phenomenon of damage to buds or clogging, poor adaptability to rice buds, and difficulty in greatly improving rice seeding efficiency
