An automatic corn seeding device

Abstract

The invention belongs to the technical field of sowing devices, and relates to an automatic corn sowing device, which includes a car body, a crawler drive device, a fertilization device, a ditching device, an automatic sowing device and a soil-covering suppression device; the crawler drive device is driven by double crawlers and has strong adhesion The ditching device can easily plan the soil; the fertilizer guide pipe of the fertilization device is connected to the container to guide the fertilizer into the trench dug, and the amount of fertilization can be controlled by controlling the diameter of the conduit entrance. The automatic seeding device enables the seed box to move up and down under the action of the spring through the cam member, so that the seeder performs periodic and intermittent sowing. The covering soil compacting device is used to collect the soil discharged by the opener, and fill the soil back into the trench, and compact the soil after sowing and filling with the compacting wheel. The invention has small overall size, light weight, portability, simple structure, low manufacturing cost, is suitable for mass production, effectively solves the problem of corn sowing in small plots of land, and has great market prospects.

Description

technical field [0001] The invention belongs to the technical field of sowing devices, and relates to an automatic corn sowing device, which is a small-sized corn sowing device specially used for small pieces of soil and driven by power for automatic sowing. Background technique [0002] Corn is one of the three major grains in my country, with a planting area of ​​24.5 million hectares and a total annual output of about 127 million tons. With the continuous development of my country's agriculture, the demand for agricultural machinery is getting higher and higher. The research on the seeder is a traditional research field of agricultural mechanization. At present, the production and manufacture of large and medium-sized seeders at home and abroad are relatively mature. In the large-scale corn planting areas in northern my country, large and medium-sized seeders are mainly used, but large and medium-sized seeders cannot be used for the many small land areas reclaimed by far...
