Soil covering type broadcast seeder

Abstract

The invention provides a soil covering type broadcast seeder. The soil covering type broadcast seeder is mainly composed of traveling wheels, a guiding rotating shaft, a soil conveying trough, a soil conveying mechanism, a soil feeding rotating roller, an outer power input shaft, a main input box, a rack, seed bins, conveying pipes, a fertilizer bin and a seed broadcast roller. Seeds are evenly broadcast through the guiding rotating shaft and the seed broadcast roller, and then the seeds are covered with mixed soil through the soil feeding rotating roller and the soil conveying mechanism via the soil conveying trough. The broadcast seeder increases the number of seedlings, the single yield per mu of wheat is increased by more than 1/3, and the problems that a traditional ridge sowing planting mode is used for a long time and consequently the yield of wheat is low, cost is high, expenses are high and earnings are low is solved thoroughly. The broadcast seeder reduces land wastage and effective consumption of various resources; higher earnings are obtained when the same investment is used. The broadcast seeder is reasonable and practical in design, so that seeding and soil covering are completed at a time, labor and time are saved, straw in fields is smashed while the seeds are broadcast, the straw serving as green manure is fully applied to soil, and the ecological environment is protected.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to an automatic agricultural machinery for spreading agricultural seeds and simultaneously covering them with soil. Background technique [0002] my country is a large country with many imports, and agricultural production has always been related to the national economy and people's livelihood. In order to increase agricultural output and improve agricultural production efficiency, the development of agricultural mechanization is placed in a very important position. At present, all kinds of agricultural machinery have been vigorously developed, promoted and applied more and more. Existing agricultural machinery kind style is a lot, and only seeding machinery just has multiple. However, looking at the existing sowing or scattered seeding machines, some have complex structures and higher prices; The straw in the farmland cannot be processed and cannot be turned into fertilizer...

AI Technical Summary

Problems solved by technology

[0004] 1. The current ridge sowing mode of wheat planting forms a ridge spacing after planting, and a certain width between ridges becomes an open space. In actual use, the wide ridge spacing is 1 / 2, and the narrow ridge spacing is 3 / 5. This kind of sowing structure has caused a lot of land to be idle and wasted, but these vacant lands also consume power, water, fertilizer and other resources in the process of plowing, watering and fertilizing

[0005] 2. Ridge sowing and planting wheat In many places, the straw is returned to the field as the base fertilizer, and some fertilizers are scattered on the ground first and then rotary plowing. Due to many reasons, the amount of straw stock in the rotary plowing land is uneven, and the piles of soil are soft and hard. And other phenomena, resulting in different depths of rotary tillage, lack of crushing quality, large gaps in the size of soil clods, jamming of seed feet or seed pieces during ridge sowing, straw entanglement of seed feet and unable to enter the ground, and occurrence of seed sowing in straw. Seeds are closely spaced, and seeds are piled together, seeds are dry and rotten, seedlings are missing and ridges are broken, and seeds cannot grow until tillers, resulting in a large reduction in wheat production
