Abstract
The utility model discloses a precision seeder with a clearing device. The seeder comprises a rack and a plurality of ditching and seeding systems, wherein the ditching and seeding systems are arranged on the rack in parallel; from front to back, each ditching and seeding system sequentially comprises a pull rod, the clearing device, a ditching device, a seed drop tube, a press wheel and a soil covering device; the clearing device comprises a metal plate which is vertically fixed on the pull rod and positioned in the front of the ditching device, and at least one metal hook which is used for clearing stalks remained in the soil before ditching and consists of a handle part and a hook part; the handle is fixed on the metal plate. By using the precision seeder with the clearing device, the residues of the stalks gathered on the ground surface are cleared away before ditching, so that sundries gathered on a soil covering fork are greatly reduced, the soil covering capability is improved, and the working efficiency of the seeder and the seeding quality are improved at the same time.
Description
Technical field
The utility model belongs to crop seeder tool field, relate to a kind of precision sower, be particularly related to a kind of precision sower of tape erasure device, this precision sower is preferably two disc trench digging wheats community precision sower, scavenge unit is installed before the trench digging metering system of such sower to improve seeding quality.
Background technology
Precision drilling is that a certain amount of seed is sowed by identical sowing depth, equal line-spacing and grain distance, makes seed sprouting environment uniformity.In wheat scientific research, to carry out the work such as the good numerous and clay fertilizer test of field test, breeding, a large amount of small plot experiments often will be set.In recent years, for raising the efficiency, reduce labour intensity, ensure seeding quality and test effect, the popularization and application of plant planter is more and more higher.Wheat community precision sower, can ensure seed in field reasonable layout, seeding quantity is accurate, spacing in the rows is even, seed level is consistent, is the creation optimum condition of growing of seed, operating efficiency is high, also can ensure to reduce error, guarantee accuracy and the reliability of test.
The two disks community precision sower structure broadly similar using in wheat subzone test at present, especially, on trench digging metering system, its basic structure comprises from front to back successively: pull bar, double disk opener, grain tube, press wheel and elasticity covering device.Generally, in production, a sown scope of the two disks of wheat community precision sower is 10 row, this means that trench digging metering system has 10, and spacing is 10-15cm each other, comparatively compact.Sower is advancing in operation, the double disk opener trench digging of each trench digging metering system, and grain tube starts to sow, and press wheel, by seed compacting, makes it fully contact with soil, and covering device is and then by earth mulch.
Before Wheat Sowing, to plough deeply whole ground, the residual crop stem of front stubble is ploughed deeply underground.But in actual production, we find, even if machinery is ploughed deeply, rotary tillage several times, residual stem stalk, weeds still can not be pulverized completely, also have at the shallow-layer of earth's surface and soil that some are residual, community precision sower is in advancing, if there is residual stem stalk, just be inevitably deposited on covering device, the latter can not well be covered soil on seed, so just, can cause some places blinding very shallow, or some places do not cover soil at all, cause seed exposed, finally cause wheat to be emerged incomplete, even if or emerge, again because blinding is freezed to death at during Wintering Period very little, final emerge quality and the later stage test examination effect that affects wheat.And if sower in the time of farm work, shut down midway and carry out foreign material cleaning, seed can occur piling up because stopping, thereby affects seeding quality.
