Description

Seeding unit

Technical field

The utility model relates to a kind of spoonful of formula seeding unit, particularly a kind of seed plate structure of seeding unit.

Background technology

Seeding unit is mainly used in the seeds of crops such as program request corn, soybean, beet, peanut, and it can be divided into versions such as disc type seeding unit, nest eye Type Seed Metering Device and spoon formula seeding unit, and the utility model is primarily aimed at a spoonful formula seeding unit and improves.

Existing spoon formula seeding unit, in kind of case, be provided with the seed plate of doing rotation synchronously and lead kind of an impeller, this seed plate and this are led between kind of the impeller and are provided with dividing plate, be distributed with 18～24 little spoons on the seed plate, this is led kind of impeller and correspondingly is distributed with 18～24 tanks, when the little spoon of seed plate by kind of lower box part fill kind of district the time, can ladle out 1～2 seed in the little spoon, and when the little spoon of seed plate rotates up kind of upper box part, unnecessary seed glides in action of gravity and falls, make in each little spoon and only stay a seed, little spoon continuation rotation when seed plate, arrive the gap position of dividing plate, a seed that only stays in the little spoon will fall into this from this dividing plate indentation, there and lead on kind of the impeller in the corresponding tank, this leads the then rotation again of kind of impeller, the rotation of the seed in this tank is driven the base outlet of below, and this seed is finally fallen in kind of the ditch.

Yet existing spoon formula seeding unit also has two weak points:

1, the seed plate of existing spoon formula seeding unit is in rotary course, the seed in the little spoon easily and dividing plate rub, cause the breakage of seed epidermis, reduced the seed survival rate;

2, existing spoon formula seeding unit only can be done the single file sowing, can't improve sowing efficient.

For this reason, the spy provides the utility model, and hope can be promoted spoonful serviceability of formula seeding unit.

Summary of the invention

In a preferable technical scheme: this seed plate is installed in the outside that this leads kind of impeller by screw.

In a preferable technical scheme: also be respectively equipped with a face shield in the both sides of this pedestal, form described kind of the district of filling between each face shield and this pedestal.

In a preferable technical scheme: also be provided with one on this face shield and be communicated to the material bin that this fills kind of district.

In a preferable technical scheme: this dividing plate outer rim is fixed on this pedestal by screw.

In a preferable technical scheme: this retaining wall is an integrative-structure with this little spoon.

In a preferable technical scheme: this retaining wall is connected with this little spoon welding or splicing.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: the utility model is by the architecture advances to seeding unit and seed plate, improve the operating efficiency of product, avoided the breakage of seed, promptly improved the survival rate of seed.

Embodiment

Please refer to Fig. 1, Figure 1A, shown in Figure 2, it is respectively the cutaway view of two spoon formula seeding units of providing of the utility model, local enlarged diagram and decomposition texture schematic diagram, because the utility model is a symmetrical structure, only shown the wherein decomposition texture of a side element among Fig. 2, as seen from the figure, the utlity model has a pedestal 10, this pedestal 10 is formed by the winding of symmetrically arranged branch seat, the both sides of this pedestal 10 are respectively equipped with a face shield 11, form one between each face shield 11 and this pedestal 10 and fill kind of a district 12, also be provided with a guiding seed on this face shield 11 and enter this and fill kind of the material bin 13 in district 12.Placed an one rotating shaft 20 in this pedestal 10, the cross sectional shape of these gyroaxis 20 mid portions is a hexagon, and be socketed with a drive sprocket 21 with hexagon endoporus, this drive sprocket 21 can be by actuating unit (as electromotor, internal combustion engine etc.) driven rotary, certainly, these gyroaxis 20 mid portions also can connect drive sprocket 21 or travelling gear by key, drive this drive sprocket 21 or travelling gear by actuating unit again, these ways of realization belong to simple replacement, just will not give unnecessary details at this.The two ends of this gyroaxis 20 are stretched into one respectively and are filled in kind of the district 12, and, the cross sectional shape of each end preferably is made as hexagon, rotate synchronously to drive kind of an impeller 22 of leading respectively with hexagon endoporus, this each lead kind of impeller 22 the outside also be installed with a seed plate 23 by screw, this seed plate 23 is evenly distributed with the individual little spoon 24 of 18～24 (definitely not limiting its quantity) along circumference, has a pit 241 that is used for holding seed 50 in each little spoon 24, and this is led kind of impeller 22 and correspondingly is distributed with 18～24 tanks 221, lead at this seed plate 23 and this and also to be provided with dividing plate 25 between kind of impeller 22, these dividing plate 25 outer rims are fixed on the pedestal 10 by screw (not giving diagram), the top edge of this dividing plate 25 also is provided with breach 251, this breach 251 is led wherein several the little spoons 24 on this seed plate 23 and this that corresponding several tanks 221 are interconnected on kind of impeller 22, enters this tank of leading kind of impeller 22 221 from this pit 241 of little spoonful 24 by this breach 251 for seed.

Since each side of the utility model fill kind the course of work in the district 12 and operation principle all with background technology partly in introduction identical, just will not give unnecessary details at this.Its difference is, by an one rotating shaft 20, can drive two seed plates 23 and two and lead kind of impeller 22 and work simultaneously, with respect to existing single spoonful of seeding unit, the operating efficiency that is doubled.

And at the seed in the little spoon 24 friction takes place and the problem of breakage with dividing plate 25 easily, the utility model also improves little spoon 24 structures of seed plate 23, see also Fig. 1, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, originally just has a pit 241 that is used for holding seed 50 in each little spoon 24, and the utility model is to have increased a retaining wall 242 at this pit 241 adjacent to a side of dividing plate 25, by this retaining wall 242 that seed 50 and dividing plate 25 is spaced apart, prevent that seed 50 and dividing plate 25 from rubbing.This retaining wall 242 both can be one machine-shaping in little spoonful 24 forming process, became the integrative-structure of little spoon 24, also can be on the architecture basics of existing little spoon 24, the part that welding or splicing are got on.

In sum, the utility model has improved the operating efficiency of product by the architecture advances to seeding unit and seed plate 23, has avoided the breakage of seed, has promptly improved the survival rate of seed.

Though the foregoing description is to be that example describes with two spoonfuls of formula seeding units, and in fact, increased the structure of a retaining wall 242 at the pit 241 of little spoon 24 adjacent to a side of dividing plate 25, also can be applied to go in the single spoonful of formula seeding unit structure.

More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
