Abstract
The utility model discloses a precision corn seed discharging device, comprising a seed discharging wheel, a seed scraping device, a seed feeding limiter and a shell. The seed discharging wheel is arranged inside the shell via a shaft; the upper opening the shell is connected with a seed box, and the lower opening of the shell is connected with a seed feeding pipe; the upper opening of the shell is hinged with the seed scraping device and the seed feeding limiter; the outer circle of the seed discharging wheel is distributed with 3-6 conic seed discharging holes, and four specifications are formed according to the number of the seed discharging hole; the four specifications can be alternatively used according to the sowing plant spacing of crops, such as corns, beans, etc., and different requirement of agriculture as well as seeding machines with different transmitting ratios. With the advantages of simple structure, high reliability and accurate seed discharging, the utility model is an idealer precision corn seed discharging device which can make the sowing of the crops of corns, beans, etc., realize bunch planting and quantity precision.
Description
The utility model relates to a kind of smart amount corn seeding unit, is installed on the sower, can make the sowing of crops such as corn, beans realize bunch plantingization, the smart quantification.
At present the seeding mode of sower has two kinds of gear type and grooved pulley types, the seeding unit of moulding has only outer groove wheel a kind of, these two kinds of seeding modes can only realize drilling or half drilling, and amount of seed metering is wayward, low, the poor reliability of seeding precision, be difficult to make the sowing of crops such as corn, beans to realize bunch plantingization, the smart quantification, in addition, up to now, also there be not a kind of essence amount corn seeding unit and sower of moulding of many specifications supporting, so that make the sowing of crops such as corn, beans realize bunch plantingization, the smart quantification.
The purpose of this utility model is to provide a kind of smart amount corn seeding unit, be a kind of seeder parts of moulding, four kinds of specifications are arranged, can select to use according to the GB spacing in the rows of crops such as corn, beans sowing or the sower of different agriculture requirement and different drive ratios, can make the sowing of crops such as corn, beans realize bunch plantingization, the smart quantification, and simple in structure, seeding is a kind of comparatively ideal smart amount corn seeding unit accurately and reliably.
Design of the present utility model is: smart amount corn seeding unit is by seed wheel 2, housing 3 formations such as grade, seed wheel 2 is installed in the housing 3 by axle 5, seed wheel 2 is rotated to seed scraping device 1 direction, housing 3 upper end open connect seeds box, lower ending opening connects grain tube, uniform 3~6 conical seeding type holes on seed wheel 3 cylindricals, according to seeding type hole number what, this seeding unit forms four kinds of specifications and models, can be according to corn, the GB spacing in the rows of crops such as beans sowing or the sower of different agriculture requirement and different drive ratios are selected to use, make corn, the sowing of crops such as beans realizes bunch plantingization, the smart quantification, a side is hinged with seed scraping device 1 with axle 5 parallel directions in housing 3 upper end open, opposite side is hinged with defeated kind of stop 4 with axle 5 parallel directions, seed scraping device 1 can be adjusted the seed scraping device angle of inclination by spacer pin and the spacing hole 8 and 9 that is arranged on the housing 3, thereby regulate the amount of sowing, defeated kind of stop 4 can be adjusted defeated kind of stop angle of inclination by spacer pin and the spacing hole 7 and 8 that is arranged on the housing 3, with adjustment seed fill cycle and packing space, thus the indirect regulation amount of sowing.
Conical seeding type hole internal diameter suitable for reading is φ 17~19mm, and the end opening internal diameter is φ 8~10mm, and the degree of depth is 8~10mm, and the seeding type hole arc chord angle that R2~3mm is arranged suitable for reading.
Seed scraping device 1 is made of base plate 10 and seeds scraper 11, base plate 10 lower ends are shaped on and the corresponding rectangular indentation in conical seeding type hole, seeds scraper 11 usefulness non-metallic elastic materials are made, seeds scraper 11 is fixed on the base plate 10 by pressing plate, and seeds scraper 11 is upper and lower adjustable, and defeated kind of a stop 4 is made of base plate 12 and limiting plate 13, and limiting plate 13 usefulness non-metallic elastic materials are made, limiting plate 13 is fixed on the base plate 12 by pressing plate, and limiting plate 13 is upper and lower adjustable.
The utility model compared with prior art, owing to adopt conical seeding type hole, can guarantee that every cave amount of sowing is reliable, accurately, being unlikely to occur seed is compressed in by seed scraping device the time in the seeding type hole, can not seeding, in addition, be provided with seed scraping device, and seeds scraper is made with non-metallic elastic material, can guarantee that the seed in the seeding type hole is filled suitably on the seed wheel cylindrical, can scrape off unnecessary seed again, when seed passes through seeds scraper, because seeds scraper has certain elasticity, be difficult for squeezing seed broken, can also be by adjusting the seed scraping device angle of inclination, the adjustment amount of sowing is provided with defeated kind of stop and limiting plate and adopts non-metallic elastic material to make, and can stop that seed seeding type hole on the seed wheel directly enters grain tube, again can be by adjusting defeated kind of stop angle of inclination, adjust seed fill cycle and packing space in the seeding type hole, thereby adjust the amount of sowing, and seed is difficult for squeezing seed broken during by limiting plate, therefore, this seeding unit is simple in structure, seeding precision height, good reliability, seed-breaking rate is no more than 8/1000ths, and hole rate is no more than 5/1000ths.
