Description

A reciprocating fork type rice water direct seeding device

technical field

The utility model relates to the field of sowing and sorting machinery, in particular to a reciprocating shift fork type direct seeding device for rice water. Suitable for sowing and rowing.

Background technique

Rice is one of the food crops with the largest planting area and the highest yield in my country. Rice planting mechanization is of great significance to increase rice yield and promote the development of rice planting industry. At present, rice mechanized planting technologies mainly include mechanical transplanting and mechanical direct seeding. Rice direct seeding technology is a light and simplified new rice planting technology. Compared with rice transplanting technology, it saves the links of seedling raising, seedling transportation, and transplanting. The planting technology process is simplified, which is conducive to improving labor productivity and the whole process of rice production. The degree of mechanization is very popular among farmers.

The development of rice direct seeding technology ultimately depends on the mechanized technology of rice direct seeding. The traditional manual direct seeding is labor-intensive and low in efficiency, which can no longer meet the needs of the development of rice direct seeding. With the development of rice direct seeding technology, the forms of rice direct seeding machines have become more diversified.

The seed meter is the core component of the seeder and the main factor that determines the characteristics and working performance of the seeder. The traditional reciprocating seed metering device is mainly composed of a seed box, a seed tray, a base, a seed delivery tube and other components. The seed tray is distributed with holes suitable for the shape and size of the seeds. Driven by power, the seed tray reciprocates between the seed box and the base. When the hole at the bottom of the seed box coincides with the hole of the seed tray, the seeds fall into the hole of the seed tray under the action of its own gravity. In the same way, when the hole of the seed-discharging tray matches the hole of the base, the seeds in the seed-discharging tray will fall into the seed delivery pipe to complete the seed-discharging. The mechanical seed metering device has good seeding versatility, stable seeding rate, and simple structure. The disadvantage is that when the seeding frequency is high, it is easy to cause an increase in the seed injury rate.
