Abstract
The utility model discloses a plough-free deep-loosening layered-fertilizing precision corn sowing machine, which comprises a land wheel, and a precision sowing part and a deep-loosening and fertilizing part which are hinged with the land wheel, wherein the upper part of the precision sowing part is connected with the upper part of the deep-loosening and fertilizing part in a hinged manner through an upper pull rod and a lower pull rod which are transversally arranged to constitute a four-link profiling mechanism, an obliquely arranged tension spring is arranged between the upper pull rod and the lower pull rod, and an adjustable pulley used for adjusting the elasticity of the tension spring is arranged on the lower pull rod. The plough-free deep-loosening layered-fertilizing precision corn sowing machine has the advantages of relatively simple structure, better profiling effect, and capability of keeping constant pressure while floating along with the ground, so as to guarantee the sowing depth standard.
Description
Technical field
The utility model relates to the agricultural machinery field, relates in particular to the no-tillage subsoiling layer by layer manuring of a kind of corn precision seeder.
Background technology
Corn is no-tillage subsoiling layer by layer manuring precision seeder can in the situation that there is stalk to cover operation, be finished the operations such as subsoiling, fertilising, simple grain precision drilling, earthing, suppression with once advancing.Owing to adopting no-tillage seeding, can reduce cleaning stalk and whole ground link, reduce production costs, stalk rots to field, and increases soil organic matter content, retains and conserve soil moisture the effect of drought-relief, waterlogging-preventing; Subsoiling sowing, subsoiling more than 25 centimetres can be broken hard for many years tillage pan, and water conservation, fertilizer conservation and impel crop root flourishing strengthen absorbing capacity; The bucket wheel seeding mechanism single grain fine sowing is adopted in the simple grain precision drilling, emerge neat, the seedling gesture is strong; Layer by layer manuring need not to topdress, and improves significantly fertilizer efficiency.
The Precision Seeding part of present corn is no-tillage subsoiling layer by layer manuring precision seeder directly hangs on the land wheel usually, when fluctuating with ground, can not keep constant pressure, thereby cause sowing depth nonstandard; The Precision Seeding of some type partly adopts feeler mechanism to connect, but structure is comparatively complicated, and pressure is regulated inconvenient, and the profiling poor effect.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of simple and reasonable that the utility model provides, and Precision Seeding partly adopts feeler mechanism to connect, and profiling is effective, and is easy to adjust, corn easy to implement is no-tillage subsoiling layer by layer manuring precision seeder.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of corn is no-tillage subsoiling layer by layer manuring precision seeder, comprise land wheel, and the Precision Seeding hinged with it part, subsoiling fertilising part, it is characterized in that: Precision Seeding part, subsoiling fertilising part top are articulated and connected by upper connecting rod, the lower link of horizontally set, consist of four link lever profile modeling mechanisms, be provided with tilting extension spring between upper connecting rod, the lower link, lower link is provided with the regulating wheel of regulating the extension spring degree of tightness.
The utlity model has following beneficial effect: owing to Precision Seeding part, subsoiling fertilising part adopt four link lever profile modeling mechanisms to connect, structure is comparatively simple, and has preferably profiling effect, can regulate easily the extension spring degree of tightness by regulating wheel, can be when fluctuating with ground, keep constant pressure, thereby guarantee the sowing depth standard.It is simple in structure, installation, easy to adjust, and then have significant practicality.
