High stubble and thick straw resistant non-tillage seeder

Abstract

A high stubble and thick straw resistant non-tillage seeder comprises a frame, and a fertilizing ditching notched disk support and a seeding support which are sequentially arranged on the frame along the forwarding direction of the non-tillage seeder; the fertilizing ditching notched disk support is provided with a fertilizing ditching notched disk; the seeding support is sequentially provided with a seeding ditching disk and a seeding disk along the forwarding direction of the non-tillage seeder; the high stubble and thick straw resistant non-tillage seeder also comprises a jamming resistant device arranged on the fertilizing ditching notched disk support and paralleling to the fertilizing ditching notched disk; the jamming resistant device comprises a knife disk and a driving device connected with the knife disk and driving the knife disk to rotate; the knife disk parallels to the fertilizing ditching notched disk; the circumferential direction of the knife disk is provided with a flail knife; and the power of the driving device is from a tractor power output shaft, a gearbox power output shaft or the fertilizing ditching notched disk. The high stubble and thick straw resistant non-tillage seeder provided by the invention can avoid jamming and can effectively guarantee the seeding quality.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a no-tillage seeder, in particular to a no-tillage seeder resistant to high stubble and thick straw. Background technique [0002] Existing no-tillage planters include a frame and successively set fertilization and ditching gap discs on the frame, sowing and ditching discs, and sowing discs\covering soil towns, pressure wheel fertilizer boxes, seed metering devices, transmission systems, Monitoring system and other components; product technology mainly comes from developed countries such as Europe and the United States. Since most of their farming areas are cultivated once a year, and their straw recovery rate is very high, when no-tillage is planted in the second year , the straws on the surface have all dried up and rotted; while in most areas of our country, two crops and three crops are harvested a year, and the straw recovery rate is low. In addition, after harvesting, sow...

Problems solved by technology

[0002] Existing no-tillage planters include a frame and successively set fertilization and ditching gap discs on the frame, sowing and ditching discs, and sowing discs\covering soil towns, pressure wheel fertilizer boxes, seed metering devices, transmission systems, Monitoring system and other components; product technology mainly comes from developed countries such as Europe and the United States. Since most of their farming areas are cultivated once a year, and their straw recovery rate is very high, when no-tillage is planted in the second year , the straws on the surface have all dried up and rotted; while in most areas of our country, two crops and three crops are harvested a year, and the straw recovery rate is low. In addition, after harvesting, sowing is necessary, and the existence of a large amount of wet and thick straw exceeds the current level. It has the weeding function of the product (the diameter of the weeding wheel is 310mm, and the radius is only 155mm. In addition, the sinking of the fertilization ditching disc and the seeding disc and the soil brought up reduce the effective working distance of the weeding wheel) In the recycled straw land or the recycled high-stubble land, the straw on the ground is piled up unevenly after crushing and the straw is crushed. The thickness (height) of the straw is far beyond the range (radius) of the mowing wheel, resulting in congestion, which cannot be cultivated normally; due to the straw Wet thick, ditching discs cannot completely cut the straw, the uncut straw is pressed into the soil, the seeds are sown on the straw, and the seedlings turn yellow or the seedlings dry out or die, and the sowing quality is seriously reduced
