Double-row, narrow-furrow and wide-ridge-back sowing and soil scraping device for corn

Abstract

The invention discloses a double-row, narrow-furrow and wide-ridge-back sowing and soil scraping device for corn. The sowing and soil scraping device comprises a soil scraping plate and two sowing devices, wherein a fixing column is fixedly connected with an inner cavity of the soil scraping plate, and the two sowing devices are uniformly distributed in the inner cavity of the soil scraping plate.The cooperative use of the soil scraping plate, the fixing column and the sowing devices, the double-row, narrow-furrow and wide-ridge-back sowing and soil scraping device for corn solves the problems that due to serious spring drought, during moisture exploring sowing, the moisture exploring depth is not enough, seedling emergence is not facilitated, after single-row moisture exploring sowing, more soil blocks on ridge backs fall off, the seedling press phenomenon is severe, growth of the seedlings is not facilitated, when the precipitation is lower, the effective utilization rate of rainwater is low, the downward growth depth of root systems of the corn is not enough and root falling is serious. The double-row, narrow-furrow and wide-ridge-back sowing and soil scraping device for corn has the advantages that the moisture exploring depth is increased, seedling emergence is facilitated, the seedling press phenomenon is relieved, growth of the seedlings is facilitated, the utilizationrate of rainwater is increased, the downward growth depth of root systems of the corn is increased and the root falling phenomenon is relieved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a soil scraper for sowing corn with double row narrow ditch and wide ridge back. Background technique [0002] The cultivated land area of ​​Shanxi Province is 4803647hm 2 , in the existing cultivated land, the area of ​​dry land reaches 3816266hm 2 , accounting for nearly 80% of the province's total arable land. Among them, the area of ​​sloping cultivated land in Shanxi Province reached 1,666,200hm 2 , accounting for 44% of the province's total dryland area. More than 50% of the dry land and sloping land are planted with maize. In the case of nine droughts in ten years in spring, the lack of moisture due to drought, the stalks of the previous stubble, and the soil were suspended, so that the emergence rate of maize was low, resulting in serious lack of seedlings and broken ridges; moreover, insufficient soil moisture, uneven and weak emergence, resulting in ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a soil scraper for sowing corn with double rows, narrow furrows and wide ridges, which improves the depth of soil moisture detection, facilitates seedling emergence, reduces the phenomenon of seedling pressure, is beneficial to seedling production, and improves the utilization rate of rainwater. , improve the penetration depth of the corn root system, reduce the advantages of serious root fall, and solve the serious spring drought. When sowing moisture, the depth of moisture detection is not enough, which is not conducive to seedling emergence. After sowing in a single row, the soil on the back of the ridge falls There are many, the phenomenon of seedling pressing is serious, which is not conducive to the growth of seedlings, when the rainfall is low, the effective utilization rate of rainwater is low, the depth of the root system of corn is not enough, and the problem of serious root fall
