Millet film mulching hill planter

Abstract

A millet film mulching hill planter comprises a machine frame, a rotary cultivation mechanism, a press wheel I, a film mulching device, a sowing case, an earthing wheel, a soil scraping plate and a press wheel II, wherein the sowing case is of an idler wheel type structure and comprises a rotary shaft, an outer wheel and an inner wheel, and a plurality of duckbill hole openers and seed discharging hole groups matched with the duckbill hole openers are distributed on the rolling peripheral surface of the inner wheel. Each duckbill hole opener is of a V-shaped structure between 0 degree and 180 degrees formed by an earth cutting pointed plate and a reset plate, wherein a reset spring in the compressed state is arranged between the reset plate and the inner wheel to enable the seed discharging hole group matched with the duckbill hole opener to be sealed by the earth cutting pointed plate, and the free end of the reset plate makes contact with soil and squeezes soil so as to open the seed discharging hole group during rotation of the outer wheel. Due to the fact that the inner wheel and the outer wheel of the sowing case roll coaxially, millet seeds are in the rolling state all the time in the sowing case, and in this way, seed discharging holes are prevented from being blocked by millet seeds, and millets seeds can fall down uniformly.

Description

technical field [0001] The invention relates to a sowing machine in the field of agricultural production, in particular to a millet film-covered hole sowing machine. Background technique [0002] Millet has the characteristics of drought resistance, barren resistance, strong adaptability, and rich nutrition. It is also a characteristic and advantageous export crop of our country, and it is also a typical representative of the "Kingdom of Miscellaneous Grains" in Shanxi Province. The development of the millet industry is an important way for farmers to increase their income and get rich, and for the country to alleviate poverty. [0003] With the extensive development and application of sowing machinery, the development of sowing machinery for corn, peanuts, soybeans and other crops is approaching precision, and the sowing effect has been warmly approved by agricultural workers and farmers. However, due to the small size, light weight, irregular shape and large difference in...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of the existing millet precision seeder that cannot precisely control the seeding amount and cannot be covered with film, the present invention provides a millet-coated hole planter. By setting a unique seeding box, during the rotation of the seeding box Cooperating with the unique duckbill hole opener, the uniform hole sowing of millet is realized, which not only saves seeds, but also reduces the workload of thinning; at the same time, it integrates production links such as film covering and sowing, which greatly improves the emergence of millet rate and seeding efficiency
