Abstract

The utility model relates to a novel corn seed discharging disk, which is the seed cleaning and seeding unit assembly of the seed discharging device of the seeding machinery. The utility model is composed of a corn seed discharging disk and a corn seed cleaning tool, one side surface of the corn seed discharging disk is processed with an annular groove, the outer circle periphery of the annular groove is crossed with the circular arc-shaped top of the shaped hole arranged on the periphery of the corn seed discharging disk, the circular arc-shaped top of the shaped hole is cut off largely, the edge of one side of the shaped hole is processed with a dovetail groove, the arranged direction of the dovetail groove and the centerline of the corn seed discharging disk has an included angle, the working end of the corn seed cleaning tool is in the shape of a sharp corner, and the upper part of the corn seed cleaning tool is processed into an inclined plane. The utility model has the advantages of favorable seed cleaning effect, low broken rate of the seeds, low failure rate, simple manufacturing process and convenient manufacture.

Description

Maize seeds distributor

The utility model belongs to and is used for interior sowing and the clear component assembly of planting of seeding unit that seeding operation uses in the agricultural machinery.

At present, in the dish seeding unit of existing all types of mechanical types garden, the structural design that generally adopts the metal Seed-cleaning tool that the type hole on the seed plate is all blocked, sealed.When clear kind and seeding operation, utilize the rigidity of metal Seed-cleaning tool itself forcibly seeding dish-type hole all to be blocked, rigid sealing, the type hole of making becomes the fixing dead space of a volume, force kind of grain in clear kind process, not become the leeway, space of pan position or activity between with respect to Seed-cleaning tool and seeding dish-type hole at all, the scrambling of seed geometry and size and complicated variation in addition, so, once rigid clear kind is very easily squeezed the seed seed bad, chopping, cause the fragmentation of kind of grain, have a strong impact on seeding quality and emergence rate, percentage of damage is up to 3-5% in actual production.On October 20th, 1988 Pang Jinfu of farm build factory of Heilongjiang Province Bin County developed the name be called the scientific and technological achievement of " Seed-cleaning tool " and obtain Patent Office of the People's Republic of China's utility model patent.The characteristics of this patent are, this Seed-cleaning tool has only blocked and has sealed a part of space in seeding dish-type hole, between Seed-cleaning tool and seeding dish-type hole, retain the displacement space of certain limit for seed, make the percentage of damage decrease to some degree of seed in the clear kind process, but because the version in seeding dish-type hole is not done any improvement design, seed can not be subjected to displacement with the type hole smoothly and sleekly in the clear kind process, the resistance of motion to seed is still bigger, therefore, the clear percentage of damage of planting is still higher, hampers the development of mechanization precision drilling.

The purpose of this utility model designs a kind of novel corn seed plate exactly, technical problem at existing corn seed plate structure existence, overall and type pore structure newly designs to it, promotion makes seed convenient, smoothly, sleekly clear the kind be taken place in clear kind process and moves, and reaches the purpose that reduces the seed percentage of damage.

Basic design of the present utility model is, the novel corn seed plate is made of corn seed plate and Seed-cleaning tool assembling, on a side of corn seed plate, processing cannelure, the garden arc top in the type hole on the Wai Yuan edge of this cannelure and the corn seed plate periphery intersects, and with the most excision of garden, type hole arc top, offside edge in the type hole towards corn seed plate direction of rotation is processing dovetail groove, and the configuration direction of its dovetail groove and the center line of corn seed plate have angle.Clear kind of working end of the Seed-cleaning tool that is complementary with the corn seed plate is angular shape, and the inclined-plane is processed on its top.

Maximum characteristics of the present utility model are exactly clear when planting seeding operation, plant effectively clearly, and it is low to plant the grain percentage of damage, and fault is few, and technology is simple, convenient during machining.

Fig. 1 is a novel corn seed plate assembly structure front view;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1, i.e. oat tail groove structure schematic diagram;

Fig. 4 is the Seed-cleaning tool structural representation.

Below in conjunction with accompanying drawing the utility model embodiment is described in detail.The novel corn seed plate is made of corn seed plate 1 and Seed-cleaning tool 2 assemblings, on a side end face of corn seed plate 1, processing cannelure 3, the garden arc top in the type hole 4 on the outer circular edge of this cannelure 3 and corn seed plate 1 periphery intersects, and with the most of excision of type hole 4 garden arc tops, the working depth of cannelure 3 should be less than 1/2nd of corn seed plate 1 thickness, offside edge in type hole 4 towards corn seed plate 3 direction of rotation is processing dovetail groove 5, the configuration direction of its dovetail groove 5 and the center line of corn seed plate 1 have angle, and the groove depth of dovetail groove 5 is identical with cannelure 3 depth dimensionses.Clear kind of working end of Seed-cleaning tool 2 is angular shape, and the inclined-plane is processed on its top.When clear kind and seeding operation, when corn seed plate 1 enters when planting section clearly with being filled to several seeds in the type hole 4, the working end becomes wedge angle, top Seed-cleaning tool 2 in the slope to push away effect with dovetail groove 5 slick and sly rise of unnecessary corn kind grain along the type hole 4 of corn seed plate 1 by arch, rising to type hole 4 when tangent, the unnecessary corn kind grain that is pushed away by arch enters rapidly in the cannelure 3, Seed-cleaning tool 2 is squeezing not, is pressing not unnecessary corn kernel at this moment, avoided fragmentation, the quantitative corn kernel that remains in simultaneously in the type hole 4 is discharged outside the corn seed plate 1.

Claims

1, be used to sow in a kind of seeding unit and clear novel corn seed plate of planting operation, it is characterized in that this dish is made of corn seed plate (1) and Seed-cleaning tool (2) assembling, on a side end face of corn seed plate (1), processing cannelure (3), intersect on the circular arc top in the type hole (4) on outer circular edge of this cannelure (3) and corn seed plate (1) periphery, and with the most excision in circular arc top, type hole (4), the working depth of cannelure (3) should be less than 1/2nd of corn seed plate (1) thickness, processing dovetail groove (5) in type hole (4) towards the offside edge of corn seed plate (3) direction of rotation, the center line of configuration direction of its dovetail groove (5) and corn seed plate (1) has angle, and the groove depth of dovetail groove (5) is identical with cannelure (3) depth dimensions.
