Roller type facility seedling raising precision seeding device with dislocation scraping function

Abstract

The invention provides a drum type facility seedling precision seeding apparatus with a staggered seed-scraping function, which comprises a drum shaft, a receiving plate, a seed box arm, a seed box, an exciter, a seeding drum, a fixing plate, a seeding pipe, a seed-scraping mechanism and an seed receiving box, wherein the seeding drum is installed on the receiving plate through the drum shaft, is in tight contact with the receiving plate and synchronously rotates along with the drum shaft; the seed box is arranged on the seed box arm fixed on the receiving plate; the exciter is installed on the seed box; the two ends of the seed-scraping mechanism are respectively fixed on the receiving plate and the fixing plate; the seed-scraping mechanism comprises a side plate, a seed-scraping plate, a front installation plate and a rear installation plate; the seed-scraping plate is provided with seed-scraping buttons; a gap between adjacent seed-scraping buttons can be adjusted through changing the positions of two seed-scraping plates; the seed receiving box is arranged below the seed-scraping mechanism. The apparatus provided by the invention has a population excitation effect, can maintain the jump of population, can perform double-side staggered seed scraping, achieves continuous sampling and precise seeding of facility seedling, improves the quality of precise seeding, and reduces the hole rate and the multiple-particle rate.

Description

technical field [0001] The invention belongs to a precision seeding device for facility seedling cultivation, in particular to a drum type facility seedling precision sowing device with the function of misalignment scraping. Background technique [0002] With the continuous progress of my country's agricultural technology, facility agriculture has achieved rapid development, and field crops have gradually implemented the seedling cultivation and transplanting planting mode. Seedling cultivation in industrial facilities is the premise and basis for crop transplanting, which can effectively protect the root system of seedlings, ensure neat emergence of seedlings, and improve survival rate. At the same time, the seedling cultivation technology in industrialized facilities uses uniform standard trays, so that the planting machinery has a standard carrier, which is convenient for the mechanized transplanting operation in the later stage. Seedling seeding device, as the key techn...

Problems solved by technology

The plate-type semi-automatic precision seeding device usually uses a reciprocating swing mechanism to drive the air sucker to suck and cast seeds, which is difficult to operate continuously, and the seeds are easy to fall off during the reciprocating movement of the air sucker, resulting in holes, and the single-seed rate and multi-seed rate are difficult. Effective control

Needle seeding device has high seeding accuracy, but low efficiency, easy to block, complicated control system, and expensive

The drum-type precision seeding device can realize continuous seeding and seeding, and the sowing efficiency is high. The existing drum-type precision seeding device includes a drum shaft and a sowing drum installed through the drum shaft, and the seeding and feeding are realized through the ventilation device. This type of seeding device generally controls the seeding quality by adjusting the negative pressure and the hole diameter of the seed suction hole, lacks an effective scraping device, and the seed cleaning effect is not good. Performance indicators such as single seed rate, multiple seed rate and void rate Poor, not yet widely used in agricultural production
