Soil Throwing Device and Planter after Sowing Wide Seed Belt

Abstract

The invention relates to a device for throwing and covering soil after sowing with a wide seed belt. The double-side baffles are fixed on both sides behind the wide seed belt rotary tillage mechanism, and a floating and adjustable upper cover plate is installed above it, and a rear retaining plate is fixed behind it. The soil rear throwing guide plate is fixed in the double-sided baffle, the soil rear throwing guide plate is inclined to the rear and upward, and there is a gap from the rear soil retaining plate; at least one seed drop is fixed through the bottom of the soil rear throwing guide plate The limiting pipe and the seeding pipe are inserted into the limiting pipe for falling seeds; the upper cover plate, the rear retaining plate, and the double side baffles form a soil limiting space, and the soil rear throwing guide plate separates the soil limiting space and makes the width The soil thrown by the rotary tiller with the rotary tiller forms an inverted L-shaped soil movement track passing through the gap. The invention adopts the rotary tillage soil and then throws it across, the seeds are evenly sown on the ideal seed bed prepared by the rotary tillage, and then the soil is automatically covered on the seeds, which reduces the sowing amount, ensures that the sowing can be penetrated into the soil, and the sowing depth is controllable and reduces the cost. Seed drying rate.

Description

technical field [0001] The invention relates to a device for throwing and covering soil after sowing with a wide seed belt, and a seeder equipped with the device, belonging to the field of seeder technology. Background technique [0002] As the most important food crops, rice and wheat are undoubtedly important to ensure their efficient and stable production. In the main rice and wheat producing areas in my country, the double cropping system of rice and wheat rotation is the main farming system. Due to the large amount of rice straw in the previous crop, the High moisture content, high toughness, sticky soil in the rice stubble field, small row spacing of the next crop wheat machine, high density of openers and easy clogging, etc. Mobile broadcasting has always been a difficulty and focus to be overcome. [0003] In the conventional mechanized sowing of wheat in the rice-wheat rotation area, it must be equipped with a straw crushing and returning machine, a rotary tiller, an...

AI Technical Summary

Problems solved by technology

The technical problem of this method is: Although the hidden danger of ditch opener blockage is eliminated, the way of rotary tillage to hit seeds causes a high rate of seed damage, increases the amount of sowing, and does not sow into the soil, the sowing depth is uncontrollable, and the seeds are dried. High rate (seeds cannot cover the soil)
