Abstract
The invention relates to a straw pressing and burying fixing device of a no-tillage planter, which comprises a fixed supporting arm, a floating profiling pressing plate, an adjusting mechanism, a left soil covering disc and a right soil covering disc, wherein a floating profiling plate is connected with the fixed supporting arm, and the left soil covering disc and the right soil covering disc are respectively connected with the floating profiling plate through the adjusting mechanism. The invention uses a soil-turning device, and the straws on both sides of the seedling zone are buried by the soil turned up by the soil-covering disk during sowing, so as to prevent the straws from being blown by wind and backfilling the seedling zone; solves the problems that the backfilling of the straws influences the emergence of seedlings and the growth of crops and even reduces the yield of grains.
Description
Technical Field
The invention relates to the field of agricultural machinery, in particular to a straw burying and fixing device of a no-tillage seeder.
Background
The no-tillage seeder is the key equipment of implementing the protective farming technique, the protective farming technique is a new agricultural production technique, require to cover the earth's surface with the crop straw, use the no-tillage seeder to sow, the no-tillage seeder is in seeding process, at first cut off the straw on the seedling area then clear up the straw on the seedling area through its straw cleaning device about, at last ditching seeding, earthing and suppression, because the straw covers at the earth's surface, can cause the straw not hard up at the in-process of clearance, when blowing wind like this, not hard up straw can be blown and filled back to the seedling area by wind, will influence crop emergence and subsequent growth, can reduce grain yield even, this kind of phenomenon is one drawback in implementing the protective farming.
Disclosure of Invention
The invention provides a straw pressing and burying fixing device of a no-tillage planter, aiming at the problem that after no-tillage planting is carried out on a straw covered land block by the existing no-tillage planter, straws are blown by wind and backfilled to a seedling zone to influence seedling emergence and crop growth; solves the problems that the backfilling of the straws influences the emergence of seedlings and the growth of crops and even reduces the yield of grains.
The straw pressing and burying fixing device of the no-tillage planter comprises a fixed supporting arm, a floating profile plate, an adjusting mechanism, a left soil covering disc and a right soil covering disc, wherein the floating profile plate is connected with the fixed supporting arm, and the left soil covering disc and the right soil covering disc are respectively connected with the floating profile plate through the adjusting mechanism.
Two horizontal angle adjusting holes are processed on the floating profile plate; the adjusting mechanism is composed of a width adjusting support arm and a vertical angle adjusting support arm hinged with the width adjusting support arm, the width adjusting support arm is fixedly connected with the floating profile plate through a horizontal angle adjusting hole and a hinge point on the floating profile plate, and the lower end of the vertical angle adjusting support arm is hinged with the left soil covering disk and/or the right soil covering disk.
The invention has the advantages and technical effects that:
1. the device is simple in structure, and the whole device consists of two soil covering disks, an adjusting mechanism (horizontal angle adjustment, width adjustment, vertical angle adjustment and pressure adjustment) and a support.
2. The invention is convenient to install and dismantle, and the whole device is arranged on the no-tillage seeding machine and can be installed and dismantled at any time.
3. The invention is convenient to use and adjust, can work by simple adjustment, does not interfere the work of the original machine, does not influence the working efficiency of the original machine, and does not increase the energy consumption.
4. The straw burying device has a good straw burying effect, can tightly bury the straws after operation, is firmly fixed, does not influence the growth of crops, and saves manpower and material resources for cleaning and backfilling the straws in the seedling zone after seeding.
