Furrowing and sowing device for separately sowing and applying fertilizer horizontally

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to a furrowing and sowing device for separately sowing and applying a fertilizer horizontally. The device consists of a parallelogram profiling frame, a hydraulic cylinder, a furrowing, seeding and fertilizing mechanism and a compacting mechanism, wherein the hydraulic cylinder is arranged between the front part of a lower swing arm of the parallelogram profiling frame and a rotating shaft I, lifts the device on a planter and adjusts the furrowing, seeding and fertilizing depth of the furrowing, seeding and fertilizing mechanism; the furrowing, seeding and fertilizing mechanism is arranged on the rear lower part of the frame, and a eudipleural furrowing blade and cutting disc composite structure reduces furrowing resistance; and compacting wheel axles of the compacting mechanism are inclined downwards, and inner edges of tires of the compacting wheels protrude, so that a backfilling effect is good. The device can realize no-tillage sowing for clay soil, has an anti-blockage function, sows and applies a fertilizer simultaneously, separates seeds and the fertilizer through a cutting disc to avoid a seed burning phenomenon, and is suitable for a no-tillage planter matched with various tillage patterns.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a ditching and sowing device for horizontally distributing seed and fertilizer. Background technique [0002] In the actual agricultural production in our country, the amount of fertilization is relatively high, and the seed fertilizer is usually applied separately to avoid the phenomenon of "burning seeds". At present, there are mainly two methods of vertical distribution and horizontal distribution. The patent No. 200810137873.1 "No-tillage deep loosening seed fertilizer vertical layered seed fertilizer opener" adopts the vertical distribution of seed fertilizer, but for clay or compacted soil, the seed fertilizer will be mixed together because the soil is not covered in time, and " Seed burning" problem. Patent No. 200710099449.8 "Ditch Opener for Separate Sowing and Fertilization" and Patent No. 200910074865.1 "Composite Disc Ditch Opener for Planter" both ad...

AI Technical Summary

Problems solved by technology

However, for the inverted trapezoidal groove or stepped groove opened by the ditch opener using the above-mentioned method of horizontal distribution of seed fertilizer, the covering effect is not good, exposed seeds are prone to occur, and the loss of fertilizer efficiency is relatively large, so the seed bed is not suitable for the needs of seed growth.
