Active anti-blocking no-tillage planter using cutaway disc hollow

Abstract

The invention provides an active anti-blocking no-tillage planter using a cutaway disc harrow, which comprises a fertilizer box, a seed box, a fertilizer discharging chain wheel, a gear box, a cross beam, a cutaway disc harrow, a furrow opener, a press wheel, a chain wheel and a spring of the press wheel, a gap-bridge chain wheel, a seed discharging tube, a fertilizer discharging pipe, a seed discharging chain wheel and the like, wherein, the diameter of the cutaway disc harrow is 400mm, and the rotation speed thereof is 400rpm; and the furrow opener is a shovel-type furrow opener provided with arc-shaped grooves, and the cutaway disc harrow is located in the arc-shaped grooves with the superposition distance between the cutaway disc harrow and the furrow opener being 36mm, thereby achieving the shearing function, preventing straw from being wound around the furrow opener and ensuring better anti-blocking ability. The no-tillage planter is capable of conducting the operations, such asstubble cleaning, rotary tilling, fertilizer burying, seeding, pressing and the like, at the same time in one step for going to the fields. Therefore, the no-tillage planter is particularly suitable for seeding the heavy rice-stubble fields in Jianghuai and Jiangnan areas and has the advantages of lower power consumption and higher passing performance.

Description

Technical field [0001] The present invention relates to a field mainly used for sandy ginger black soil in Huaibei, Jianghuai and Jiangnan regions, where the previous crops are soybeans, rice and other crops. For the no-tillage sowing of soybeans and other crops, stubble removal, ditching, sowing, fertilization, and suppression can be completed in one trip, especially the no-tillage seeder that can realize the deep application of chemical fertilizers and has active anti-blocking functions. Background technique [0002] At present, known no-tillage seeders use special shovel openers for ditch sowing or rotary tillage seeders for sowing. The above two methods have good adaptability to the sandy soil in North China, but for the sandy ginger black soil in Huaibei and Jianghuai and the sticky heavy soil in the Jiangnan area, the power consumption is very large, and it is easy to cause damage to the shovel opener or rotary tiller , affect the quality of sowing. The main reason i...

Problems solved by technology

[0003] In order to overcome the problems that the existing no-tillage seeders and rotary tillage seeders consume too much power and the ditch openers are easy to block for the sand ginger black soil in Huaibei and the sticky heavy soil between the Jianghuai and Jiangnan regions, the present invention provides an active anti-blocking No-tillage seeder for paddy stubble field with notched disc harrow. The seeder works directly on the stubble field where the previous crops are soybeans, rice and other crops. One operation can complete stubble removal, ditching, sowing, fertilization, suppression and other operations at the same time.
