Abstract

The utility model relates to a quantitative dibbler, belonging to agriculture seeding machinery. The quantitative dibbler comprises a storage rotary drum, a rotary shaft, a feeding pipe, a discharging pipe, a classifying plate, etc. The feeding pipe is bent shape and is arranged on the inner circumference of the storage rotary drum; the classifying plate is inserted in the pipe mouth of the feeding pipe. With the advantages of compact structure, convenient operation and high speed, the utility model does not damage seeds, and can adapt to different particle diameters. As a quantitative and nonadjustable small-sized simple seeding device, the utility model is particularly applied to small sized seeding in hills and mountain areas.

Description

Quantitative dibbler

The utility model belongs to agricultural seeder machinery.

In the prior art, the dispenser of mechanical type planter has that the nest eye is wheeled, mill is wheeled etc.As Chinese patent 87202053 disclosed hole-ground film sowers, it is wheeled that its dispenser just belongs to the nest eye, and it is to limit the slit of planting between plate, base plate and the seed wheel according to the size of different seeds by adjusting, and realizes the capsule kind and charges seed.This mechanism abrades seed easily, even causes the seed fragmentation, and structure more complicated, not easy-maintaining.

The purpose of this utility model is to overcome weak point of the prior art, and provides a kind of simple in structure, compact, and is easy to use, the compact simplified dibbler of broken seed, quantitative spacing.

The purpose of this utility model can realize by following measure: quantitatively dibbler is made up of bin stock cylinder, turning cylinder, drainage conduit, backstay, push rod, passage and gradation plate etc.This passage is a bending, and the one end is that discharging opening is installed on the bin stock cylinder inner periphery, and is communicated with drainage conduit on the bin stock cylinder excircle; Be fitted with the gradation plate in the other end mouth of pipe, have charging aperture on the tube wall of gradation plate one side, the angle α between this charging aperture and the gradation plate plate face is 90-120 °.Turning cylinder is installed in bin stock centre of the drum, and backstay, push rod front fork are fixed on two spindle noses of turning cylinder with nut.Be provided with the charging door of sealing in the side of bin stock cylinder.

The gradation plate of this quantitative dibbler is a tabular component, and its width should be less than the cross section of passage, and according to the shape and the size of seed, the gradation plate is provided with several nest eyes, dark 3/5～2/3 of the pellet diameter that is at least of its nest eye.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the front view of quantitative dibbler;

Fig. 2 is the vertical view of quantitative dibbler;

Fig. 3 is a passage mouth of pipe schematic diagram;

Fig. 4 is the passage mouth of pipe cutaway view of Fig. 3;

Fig. 5 is a gradation plate schematic diagram.

1, drainage conduit 2, passage 3, gradation plate 4, turning cylinder 5, bin stock cylinder 6, spring 7, hook 8, push rod 9, backstay 10, charging door 11, portable plate 12, charging aperture 13, nest eye 14, sieve powder hole by force

As can be seen, the passage 2 of bending is installed on bin stock cylinder 5 inner peripherys from Fig. 1, Fig. 2, and is communicated with drainage conduit 1 on being installed in bin stock cylinder 5 excircles.Be distributed in passage and drainage conduit on the bin stock roll circumference, its quantity can according to the cave in when sowing apart from or spacing in the rows determine.The side of this bin stock cylinder 5 is provided with the charging door 10 of sealing, and turning cylinder 4 is installed in bin stock cylinder 5 centers, and backstay 9, push rod 8 usefulness nuts are fixed on two spindle noses of turning cylinder 4.Spring 6 one ends hooks is on bin stock cylinder 5, and other end hook is on hook 7 by force, and hook 7 is contained on the portable plate 11 of drainage conduit 1 by force.

As shown in Figure 3, gradation plate 3 is inserted in the mouth of pipe of passage 2, has charging aperture 12 on the tube wall of gradation plate 3 one sides, and the angle α between this charging aperture and the gradation plate plate face is 110 °.As can be seen from Figure 5, this gradation plate 3 is tabular, according to the needs of pellet diameter, size and quantity, establishes the nest eye 13 of several recessed plate faces on gradation plate 3 in the use.For dust on the pellet and earth are missed, avoid stopping up gradation cehla eye, be provided with sieve powder hole 14 in the bottom of nest eye 13.

Operation principle of the present utility model is as follows: along with rotating counterclockwise of bin stock cylinder 5, seed enters passage 2 by charging aperture 12, and a part of seed is stayed in the nest eye 13 through gradation plate 3, and unnecessary seed is along with the inclination of gradation plate 3 goes out along a side leakage.When passage 2 forwarded the cylinder oblique upper to bin stock cylinder 5, the seed in the nest eye 13 fell into passage 2 by deadweight, and enters in the drainage conduit 1; Cylinder is rotated further, and when the hook by force 7 on the drainage conduit 1 contacted with backstay 9, the portable plate 11 on drainage conduit 1 under the effect of power was opened, and casts seed, realizes connecing the quantitative program request in cave, and portable plate 11 resets under the effect of spring 6 then.

Effect of the present utility model is: this quantitative dibbler belongs to compact simplified seeding apparatus, and compact conformation, easy to use can adapt to different-grain diameter, and gradation speed is fast, is specially adapted to the needs of Hills small size sowing. Can be used for the rationed of general granular article behind this device certain modification. The sorting packing of some small business adopts this device just can greatly increase work efficiency.
