Strip seeding production line for raising hybrid rice seedlings

Abstract

The invention discloses a strip seeding production line for raising hybrid rice seedlings. The production line is composed of a front part, a rear part and various mechanisms, wherein a driving motor, a drive device, a fertilizer applying mechanism, a subsoil mechanism, a brushing and flattening mechanism and a groove rolling mechanism are arranged on a front rack; a driving motor, a drive device, a seeding mechanism, a water spraying mechanism and a soil covering mechanism are arranged on a rear rack; and all the mechanisms are driven in a stepless synchronization manner and are respectively provided with a regulating device, so that the capacity of each mechanism can be regulated according to different needs. After an empty seedling disk passes an inlet, the drive devices convey the seedling disk into the production line, and thus the seedling disk can be driven at the bottom of each mechanism, wherein the fertilizer applying mechanism applies a thin layer of seedling strengthening agent fertilizers at the bottom of the seedling disk; the subsoil mechanism spreads subsoil on the fertilizers distributed in the seedling disk; the brushing and flattening mechanism brushes the subsoil on the surface of the seedling disk so as to flatten the subsoil; the groove rolling mechanism rolls 18 trapezoidal grooves in the subsoil on the seedling disk; the strip seeding mechanism quantificationally sows sprout seeds into the grooves in time by virtue of a strip seeding device; the water spraying mechanism firstly sprays atomized water to position the seeds in the grooves and then sprinkles water for the secondary time so as to ensure that the water is completely permeated into the subsoil; and the soil covering mechanism overlays a thin layer of fine soil on the seeds to prevent the exposure of the seeds so as to ensure that the seeds are not influenced, so that the one-time seeding is finished by the production line. The production line provided by the invention is suitable for strip seeding in the raising of the hybrid rice seedlings.

Description

technical field [0001] The invention belongs to the technical field of rice seedling raising equipment, and relates to a rice seedling raising seeder, in particular to a hybrid rice seedling raising strip seeding assembly line. Background technique [0002] In recent years, with the continuous maturity of rice seedling raising and seedling technology, the planting of early rice and continuous cropping late rice in our city has basically implemented mechanized seedling transplanting. There is a hybrid rice seedling raising and seeding line that is environmentally friendly, cost-saving, and yield-increasing. It is key to reduce the rate of missed insertion and the amount of labor after machine insertion. The original fertilization is: the seedling-strengthening agent is directly sprinkled on the seedling board to fertilize the bed soil, and the finished seedlings will have missing or dead plants. At present, soil-mixing is used for fertilization, and seedling-strengthening ag...

AI Technical Summary

Problems solved by technology

However, these three schemes still have the following defects: 1. The seedling strengthening agent is difficult to be evenly mixed by manual mixing, resulting in rotten seedlings and dead seedlings; 1. Too many missed insertions will cause holes, and artificial seedlings still need to be filled; 4. The requirements for seeds are high, and buds or rough seeds are easy to be blocked in the diversion groove when sowing; 5. The water spray mechanism cannot meet the water seepage requirements when sowing seedling trays ;
