Corn double-line width ridge deep ploughing layering fertilizing seeder

Abstract

The invention provides a corn double-line width ridge deep ploughing layering fertilizing seeder comprising a front subsoiling layering fertilizing unit and a rear precise sowing unit; the front frame of the subsoiling layering fertilizing unit and the rear frame of the rear precise sowing unit are connected through a parallel four-bar connecting rod member. The advantages are that the corn double-line width ridge deep ploughing layering fertilizing seeder can complete subsoiling, fertilizing, ridging, shaping and precise sowing works in one time after entering field, so the machine does not need to enter the field for many times, thus enhancing soil water storage capability, improving fertilizer utilization rate, and increasing grain yield; two gutter-ploughs and fertilizer pipes are reasonably arranged so as to realize layering fertilizing effect.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a double-row deep plowing layered fertilization seeder for large corn ridges. Background technique [0002] Seeding is an extremely important part of the agricultural production process. It is necessary to sow seeds at the right time according to the requirements of agricultural technology, so that the crops can obtain good development and growth conditions, so as to ensure that the seedlings are full and strong, and lay a solid foundation for increasing production and harvest. Mechanical sowing has good quality and high productivity, which can ensure timely sowing, and at the same time create good conditions for field management operations. Therefore, mechanical sowing is widely used in our country. [0003] A planter is a planting machine that uses crop seeds as the object of sowing. It is used for a certain type or a certain type of crop. It is often named by the name of...

Problems solved by technology

Through investigation and analysis, the current corn planting mode in Northeast China, especially in Liaoning, is mainly ridge farming, most of which adopt the traditional uniform ridge planting method. Generally speaking, there are the following problems: (1) Long-term traditional farming The mode makes the soil form a hard plow layer, and the soil is severely compacted, which is not conducive to crop growth; (2) The machine tool enters the ground many times, causing compaction of the soil, reducing its air permeability and porosity, and increasing power consumption at the same time , which increases the operating cost; (3) Under the traditional uniform ridge planting mode, the contact surface between the soil and the air is relatively large, resulting in faster water loss, and poor light and ventilation

[0011] Based on the above analysis, combined with the actual needs of production, the existing technology lacks a mechanized equipment that realizes the above-mentioned multiple functions at one time
