Problems solved by technology

[0003] At present, the soil working mechanism of agricultural machinery with the function of crushing soil can be divided into active rotary type and passive rotary type. The amount of soil breaking is large, and the structure of the soil plow layer is severely damaged, so it is not suitable for no-tillage operations. The passive crushing roller (ZL201310000902.0) is generally suitable for plowing and land preparation machinery, and it does not have the function of loosening the soil after plowing. It is an independent operation and cannot be used in conjunction with a no-tillage planter
[0004] International mainstream no-tillage seeders generally use corrugated round coulters (ZL201010004737.2) as their loosening parts. The folds of corrugated circular coulters are relatively large, and in the cultivation environment with heavy soil, they often adhere to more seed bed soil. When operating at high speed, the structure of the soil plow layer is seriously damaged, resulting in inconsistent sowing depth and poor contact between seeds and soil. , affecting seed germination
Narrow corrugated round coulters have better soil penetration performance due to their smaller corrugated width, and will not throw away a large amount of seed ditch soil like wide corrugated cutter heads, but the loose soil width is small, and the soil loosening effect is poor. Provide good conditions for subsequent sowing
[0005] Whether it is a wide corrugated round coulter or a narrow corrugated round coulter, they can only adapt to a certain range of working environments during work.
In addition, due to its own structure, the corrugated round coulter only has a loosening effect on the soil, but does not have the function of crushing the soil. After loosening, the larger soil clods are easy to form air pockets, and the seeds and soil cannot be obtained. Full contact, the seed bed is easy to run away moisture, which is not conducive to seed germination

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings.

[0049] Such as figure 1 As shown, a no-tillage seeder strip soil loosening mechanism is installed at the front end of the sowing unit, and is used to loosen the soil in the sowing range in advance when the no-tillage seeder advances.

[0050] Such as figure 2 As shown, a no-tillage seeder belt loosening soil mechanism is composed of a connecting frame, a star-shaped cutter head assembly and a soil crushing wheel assembly. The connecting frame includes a fixed plate and two parallel support plates vertically fixed on the front end of the fixed plate. The No. 1 star-shaped cutterhead 7 of the star-shaped cutterhead assembly is arranged on the outside of the No. 1 bracket plate 3 of the connecting frame through the No. 1 star-shaped cutterhead fixed shaft 5, and the No. 2 star-shaped cutterhead 8 of the star-shaped cutterhead assembly The No. 2 star-shaped cutter head...

Abstract

The invention discloses a soil-strip breaking mechanism of a no-tillage planter, which comprises a connection frame, a star-shaped cutter disc assembly and a soil-breaking wheel assembly, wherein the star-shaped cutter disc assembly comprises two star-shaped cutter discs with identical structures; the two star-shaped discs with the identical structures are respectively set outer sides of two support plates in symmetrical way through a star-shaped cutter disc fixation shaft; the soil-breaking wheel assembly comprises a spring combination structure, a soil-breaking wheel combination structure and two cranked level supports; the two cranked level supports are rotatingly connected to outer sides of the two support plates of the connection frame through a connection shaft; the spring combination structure is fixed on top surfaces of the two support plates; a front end of the spring combination structure is rotatingly connected to upper arms of the two cranked level supports through the connection shaft; and the soil-breaking wheel combination is rotatingly connected to lower arms of the two cranked level supports through a rotary shaft and the soil-breaking combination is located below the connection frame. According to the invention, the soil strip breaking mechanism is mounted on a front end of a planting monomer of the no-tillage planter; before the no-tillage planter moves forward, strip breaking to the soil within the planting range is performed in advance.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a strip loosening soil mechanism for a no-tillage planter, which can loosen the soil in a seed bed in strips, create ideal seed bed operating conditions for sowing, and improve the consistency and consistency of seed germination. Germination rate. Background technique [0002] No-tillage sowing is a new type of sowing technology that directly sows on the surface covered with straw or stubble and without prior soil tillage. Because the surface soil of no-tillage is relatively solid and covered with straw, soil tillage parts or mechanisms are generally installed on the sowing unit of no-tillage seeders. Sowing ditching, covering soil, and pressing create suitable soil cultivation conditions, which is one of the key mechanisms of no-tillage seeders. In order to better complete the no-tillage seeding operation, the soil tillage mechanism of the no-tillage...
