Seed rolling device and method for rice precision hole direct sowing machine

Abstract

The invention provides a seed rolling device and a seed rolling method for a rice precision hole direct sowing machine. The device comprises a frame crossbeam, a positioning mechanism and a rolling mechanism, wherein two ends of the frame crossbeam are respectively provided with direct sowing machine connecting mechanisms, and the rice precision hole direct sowing machine is connected outside the direct sowing machine connecting mechanisms; the rolling mechanism comprises an adjusting rod, an upper adjusting nut, an upper spring, a lower spring, a lower adjusting nut, a connecting sleeve, a connecting rod, a roller rack, a roller and a scraper, wherein the adjusting rod is connected with the connecting rod, the upper adjusting nut is connected with the upper end of the adjusting rod and the upper spring, and both the upper spring and the lower spring are sleeved on the periphery of the rod section of the connecting rod; the lower adjusting nut is connected with the lower end of the adjusting rod and the lower spring; the connecting sleeve is connected with the frame crossbeam; the connecting rod is connected with the connecting sleeve and the roller rack, and the roller is connected to the roller rack; and the scraper is connected with the roller rack and arranged in front of the roller. According to the device and the method, sowed seeds can be effectively pressed into the soil, and the problem of contact area of the seeds and the soil is effectively solved.

Description

technical field [0001] The invention relates to the technical field of rice sowing, in particular to a seed rolling device and method of a rice precision hole seeding machine. Background technique [0002] In recent years, direct seeding of rice has become an important method of rice planting. Rice direct seeding saves labor, labor and cost. The existing rice direct seeding machine, the seeds are generally exposed on the soil surface after direct seeding, and there are the following defects: first, it is easily affected by the accumulation of water in the field during sowing, and the rain washes easily to make the seeds float and move; second, it is easy to be affected by freezing Or the sun exposure will affect its germination rate, especially early rice, the seed germination rate is low at low temperature, and the sun exposure will affect the seed germination when the field surface is dry; third, the seeds are on the soil surface, which are prone to stacking and contact wi...

AI Technical Summary

Problems solved by technology

The existing rice direct seeding machines generally expose the seeds on the mud surface after direct seeding, and have the following defects: first, they are easily affected by field water during sowing, and the seeds are easy to float and move when washed by rainwater; second, they are easy to be affected by freezing. Or sun exposure will affect its germination rate, especially for early rice, the germination rate of seeds at low temperature is low, and when the field surface is relatively dry, the sun exposure will affect the germination of seeds; third, the seeds are easy to stack on the mud surface and contact with the soil The surface is small, which is not conducive to germination; fourth, it is easily affected by birds and insects, and the seeds exposed on the mud surface are easy to be eaten by birds
