Paddy rice seedling-cultivation sowing machine

Abstract

The invention relates to a paddy rice seedling-cultivation sowing machine belonging to a sowing machine. The paddy rice seedling-cultivation sowing machine comprises a bracing frame and a conveying guide rail arranged on the bracing frame; the paddy rice seedling-cultivation sowing machine also comprises a conveying motor, a soil paving apparatus, a soil brushing apparatus I, a water spraying apparatus, a sowing apparatus, a soil covering apparatus and a soil brushing apparatus II which are successively arranged on the conveying guide rail; and the paddy rice seedling-cultivation sowing machine also comprises an atomization apparatus arranged behind the soil brushing apparatus II and on the conveying guide rail. The atomization apparatus comprises an atomization box, a spray device and an electric control device; the atomization box is fixedly connected with two conveying guide rails; the spraying device comprises a water pump, a water suction pipe, a water outlet pipe, an atomization water pipe, an atomization nozzle and atomization water pipe positioning devices; the atomization water pipe positioning devices are arranged on two opposite sidewalls in the atomization box; the atomization nozzle is connected with the atomization water pipe; the atomization water pipe is positioned on the atomization water pipe positioning device; and the power supply of the electric control device is electrically connected with the water pump.

Description

technical field [0001] The invention relates to a seeder, in particular to a rice seedling seeder. Background technique [0002] Along with the development of agricultural technology, adopt mechanized seedling raising more and more widely, so the application of paddy rice seedling raising seeder is also more and more, but existing rice seedling raising seedling still has many defects. Without a counting device, the workload of the seeder per period of time usually requires operators to count by manual counting. Manual counting has disadvantages such as error-prone and low efficiency. Seedling raising with a rice seedling seeding machine needs to go through the processes of spreading soil, spraying water, brushing soil, sowing, covering soil, and brushing soil again. After the seeder completes the sowing operation, the operator places the seedling tray in the seedling shed. Moisture is needed, and it is also necessary to carry out a water spray operation to the seedling tray...

AI Technical Summary

Problems solved by technology

The seeding wheel of the existing rice seedling seeding machine has the disadvantages that the end cover is easy to loosen and the seeding is not uniform enough. The uneven seeding is easy to cause the phenomenon of uneven number of seedlings per hole and high density, which directly affects the quality of seedling raising and does not meet the requirements of machine transplanting.
