Description

The compound filling seeds precision seeder

The utility model belongs in the agricultural machinery configuration and is installed in the feed mechanism assembly that uses on the sower.

At present, in the agricultural production of China, use more precision seeder to mainly contain two kinds: a kind of is the side-feeding vertical plate precision metering, have higher operating efficiency and operation quality preferably, but because the seeding process of this seeding unit is that Seed-cleaning tool forcibly all blocks or block a part with seeding dish-type hole, form the fixing dead space of a volume, make kind of grain in clear kind process between with respect to Seed-cleaning tool and seeding dish-type hole basic throw to have become pan position or movable leeway, the scrambling of seed geometry and size and complicated variation in addition, so in clear kind process, very easily squeeze the seed seed bad, chopping, influence seeding quality and emergence rate, in actual production, percentage of damage is up to 5%; Another kind is radially to fill kind of a cave nest formula precise seeder, and this seeding unit is made into well-regulated cave nest, utilizes brush-wheel to plant clearly, and its course of work is seed wheel and brush-wheel switched in opposite, and having reached ideal can chip-proof clear kind.The shortcoming of this seeding unit is that brush-wheel weares and teares easily, and during sowing, it is a little high to charge seed, and sows inaccurate, particularly more outstanding when the sowing soybean.

The purpose of this utility model is exactly at single side-feeding or radially fills the problem that kind of seeding unit exists, design a kind of compound filling seeds precision seeder, kind of the process of filling of this device has and radially fills kind and side direction is filled the simultaneous two kinds of functions of kind, it is compound filling seeds, cancellation Seed-cleaning tool or brush-wheel parts in the overall structure, need not plant parts clearly and can finish automatically clear the kind, reaching seed-filling rate height, no hole, seed does not have that fragmentation, seeding operation quality are good, the purpose of realization precise sowing.

Basic design of the present utility model is, this device is by sprocket assemblies, housing, the combined type seed plate, seed guiding groove, divide flash barrier, grain tube and loam cake constitute, flash barrier was separated into the inner chamber of housing and filled kind of chamber and seeding chamber two parts its minute, by stifled kind of dish, seed plate, combined type seed plate and sprocket assemblies that central baffle is formed are assembled into one, this combined type seed plate be configured in the housing inner chamber fill kind of chamber and seeding indoor, and be packed on the sidewall of housing inner chamber seeding chamber, the seed guiding groove that cross section is " recessed " font is complementary, grain tube is installed in and covers, its outlet is configured in fills kind indoorly, and can carry out highly adjusting up and down.

The utility model is compared with existing various mechanical precision seeders, the novelty development is arranged on seeding mechanism, overcome and planted a grain percentage of damage height, sowing precision is poor, service life is short shortcoming, have fill kind effective, sow not the hole, clearly automatically plant the characteristics not broken, easy to use, stable and reliable for performance, that operation quality is good.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The compound filling seeds precision seeder is made of sprocket assemblies 1, housing 2, combined type seed plate 3, seed guiding groove 4, branch flash barrier 5, grain tube 6 and loam cake 14, its minute, flash barrier 5 fixedly was assemblied on housing 2 intracavity sidewalls, the inner chamber of housing 2 tightly is separated into fills kind of chamber 10 and seeding chamber 11 two parts; By two stifled kind of dishes 7, the combined type seed plate 3 that two seed plates 8 and central baffle 9 are formed is assembled into one by securing member and key and sprocket assemblies 1, and be configured in housing 2 inner chambers, and the part of this combined type seed plate 3 is positioned at fills kind of chamber 10, another part is positioned at seeding chamber 11, wherein be positioned at seeding chamber 11 combined type seed plate 3 part be packed on 11 sidewalls of housing inner chamber seeding chambers 2, the seed guiding groove 4 that cross section is " recessed " font is complementary, be the outside dimension of the outside dimension of central baffle 9 greater than seed plate 8, and the gap between the groove floor of seed guiding groove 4 is less than the sowing particle size, the groove of seed guiding groove 4 contains seed plate 8 outer circumference surfaces, and the interplanar gap, outer end of the interior sidewall surface of its groove and seed plate 8 is also less than the sowing particle size; Grain tube 6 can be realized highly being installed on the loam cake 14 of adjusting, and the outlet of its kind grain is configured in fills in kind of the chamber 10.Be processed in the front portion in each type hole 13 of the seed plate 8 of circular peripheral-mill type rounding off arc fill kind of guiding circular arc 12.For adapting to Different Crop, different sowing agronomy needs, this device has the combined type seed plate 3 that constitutes with 7 and seed plates of two stifled kind of dishes 8; (1), when the outside dimension of stifled kind of dish 7 during less than the outside dimension of seed plate 8, stifled kind of dish 7 is planar disc; (2), when the outside dimension of stifled kind of dish 7 during greater than the outside dimension of seed plate 8, stifled kind of dish 7 is the disc shape, the dish mouth is outwards installed.According to sowing line number requirement, in housing 2, center line that can housing 2 is equipped 1-3 group combined type seed plates 3 of center line symmetry.

When operation is used; the sower chain drives sprocket assemblies 1 and counterclockwise rotates; combined type seed plate 3 is simultaneously by counterclockwise rotating; when when its type hole 13, going into to fill the kind heap of kind of chamber 10; seed is from radially being filled to simultaneously in type 13 holes of seed plate 8 with side direction; when heap is shifted out kind in the type hole 13 that is full of seed; the seed of 13 outsides, type hole is by the automatic landing of self gravitation; fall in the kind heap that fills kind of chamber 10; the seed of 13 the insides, type hole of combined type seed plate 3 enters in the seeding chamber 11 under the protection of stifled kind of dish 7; under the sealing process of seed guiding groove 4; seed is discharged in the type hole of combined type seed plate 3 by gravity and centrifugal force; by the guide effect of seed guiding groove 4, make that seed is well-regulated discharges in device, finish the precise sowing operation.The utility model is applicable to that large, medium and small type precision planter installs and uses.
