A two-year wheat hole seeder for no-tillage and one film

Abstract

The invention relates to the field of agricultural machinery and equipment, in particular to a no-tillage one-film two-year wheat hole seeder, which includes a frame and a soil knocking mechanism, a rubbing mechanism and an in-line sowing mechanism arranged on the frame. Mechanism, kneading mechanism and in-line seeding mechanism are arranged sequentially along the traveling direction of the vehicle. The invention facilitates the insertion of the duck-billed cavitation device into the soil and prevents the duck-bill cavitation device from picking or hanging the film.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a wheat hole seeder for no-tillage, one-film and two-year use. Background technique [0002] Film-covered cultivation is the main cultivation technology to achieve high grain yield in northern my country. The links from ploughing, fertilization, sowing, field management to harvesting are different from open-field cultivation. The film-covered wheat hole planter must meet the agronomic requirements of film-covered wheat cultivation. At present, the most widely used is the drum duckbill type mulching machine. The hole punching planter has changed the sowing method of ditching, sowing and covering soil of the traditional seeder, and changed to drilling, sowing and covering soil. Therefore, it has the characteristics of low working resistance and high sowing accuracy, which effectively meets the requirements of precision seeding for in-row seeds. However, this kin...

Problems solved by technology

The hole punching machine has changed the sowing method of ditching, sowing, and soil covering of the traditional seeder, and changed it to drilling, sowing, and soil covering. Therefore, it has the characteristics of small working resistance and high sowing precision, which effectively meets the needs of precision seeding in the industry. Plant spacing requirements, but this kind of planting machine has a high dislocation rate between seed holes and membrane holes, and poor particle number uniformity, which is easy to cause holes, low pass rate of hole particle numbers, and unadjustable sowing depth, hole, and row spacing.

The main reason is that after the seed metering device of the drum duckbill hole seeder is seeded, the seeds need to be distributed to each hole forming device twice, and the time for the free fall of the seeds from the seed guide tube to the hole forming device needs to be separated by several seconds, so that the number of holes is qualified. The rate is low; the second is to adopt the roller duckbill type hole forming device, and its movement track is a curved cycloid, which cannot realize straight insertion and straight out. After the film hole is formed, the top of the duckbill will produce a film or hanging film, and the film will be formed by repeated stretching. The third is that different varieties, different soil conditions, and different sowing seasons require different sowing depths, different hole spacing, and row spacing to ensure a better emergence rate. Adjustment

The fourth is that the insertion speed of the hole forming device is too slow, the resistance is too large, the duckbill is easy to block the hole, the soil is caught, and sometimes it is difficult to open the soil. In view of this, my country has developed several in-line film-covered hole seeders. After planting, the misalignment rate of the film holes of the seed planter is reduced, the number of holes is uniform, and the situation of tearing and picking the film of the cave forming device is solved. However, due to the high insertion resistance of the mechanism used or the inability to insert because the ground surface is too hard, it is restricted. Promote smoothly
