Description

A kind of seeding unit of seeds having abnormal shape

Technical field

The utility model relates to a kind of seeding unit, the seeding unit of a kind of seeds having abnormal shape of more specifically saying so.

Background technology

Seeding unit is the critical piece of sower, be configured on the frame of sower, during sower work, agriculture requirements such as spacing in the rows according to crop-planting, seed in the seed-box is sowed in the pipe by in good time, an amount of being discharged to of seeding unit, broadcast in the soil by the pipe of sowing, finish the quantitative sowing of crop.

Seeding unit commonly used is divided into strip sowing seed discharge device and bunch planting seeding unit two big classes.Strip sowing seed discharge device comprises outer groove wheel, interior grooved pulley type, dial-type, spoon formula, abrasive disk type, floral disc formula, centrifugal and pneumatic type; The bunch planting seeding unit comprises hole roller formula, type pore area formula, finger-clipped and pneumatic type.The seeding unit of above-mentioned various versions can satisfy the seeding requirement of seed class crop seeds such as wheat, corn, soybean, peanut, cotton, rape substantially, but inapplicable to the seeding of block seeds in irregular shape such as potato.At present, the special-purpose seeding unit that is used for Sowing machine for potatoes mainly contains aculeus type, finger-clipped, spoon belt and plate valve formula." marathon " that the silent enginerring works of West Germany carat produce before the spoon belt (MARATHON) seeding unit on the two row potato planter is representative, this seeding unit not only complex structure, bulky, cost is high, and only be applicable to that shape is the seed of circle or sub-circular, for being kind of a period of the day from 11 p.m. to 1 a.m with the potato ball that cuts into out-of-shapes such as multiple edge body, differ in size, in the process of seeding, when seed is maked somebody a mere figurehead or obstruction when seeding unit trickles easily by seed-box, cause the seed cutout, cause seeding unit to omit in printing.China Patent No. is the plate valve formula seeding unit that discloses a kind of potato sowing in the application documents of 00226787.X, this plate valve formula seeding unit, from its structure and the course of work, can only be applicable to that equally shape is the potato seed of circle or sub-circular, for being kind of a period of the day from 11 p.m. to 1 a.m, can not normally sow with the potato ball that cuts into out-of-shapes such as multiple edge body, differ in size.The seeding unit of aculeus type and two kinds of versions of finger-clipped, its deficiency is a complex structure, damages seed in the process of seeding easily, seeding speed is high more, and is serious more to the damage of seed.

Because it is the seeding of seed that the special-purpose seeding unit of above-mentioned Sowing machine for potatoes all is not suitable for out-of-shape, the potato cutting of differing in size, and at present in the potato planting of China great majority be to be seed with the potato cutting, therefore still adopt the artificial planting mode of original backwardness, labour intensity is big, efficient is low, the work time cost height becomes a big bottleneck of potato planting, and seriously having restricted with the stripping and slicing is the industrialization of the potato planting of seed.For this reason, China classifies the mechanization of potato planting as emphasis science and technology public relations problem in the agricultural machinery Eleventh Five-Year Plan.

Summary of the invention

The purpose of this utility model provides and a kind ofly is applicable to that the stripping and slicing with crop and fruit is the seeding unit of the seeds having abnormal shape of seed.

In order to realize above-mentioned purpose, the seeding unit of the seeds having abnormal shape that is provided, comprise the seed-box that is fixed on the sower frame and the pipe of sowing, be installed in drive sprocket axle and driven chain wheel shaft on the sower frame, be set with drive sprocket on the drive sprocket axle, be set with driven sprocket on the driven chain wheel shaft, be connected with the seeding chain between drive sprocket and the driven sprocket, its design feature is to be connected with the connecting rod that is intervally arranged on the seeding chain, the end of each connecting rod is connected with gets kind of a cup, the ascent stage of the seeding chain bottom surface of passing seed-box lacks the hole and enters the seed-box inner chamber and stretch out from the opening end of seed-box, the descending branch of seeding chain protrudes into the tube cavity and stretch out from the bottom of the pipe medial surface of sowing of sowing from the opening end of the pipe of sowing, and the bottom surface of seed-box lacks the position, hole and is coated with hinged with seed-box bottom surface valve on one side.

Above-mentioned valve is a block rubber.

In order to make the spacing of broadcasting the seed in the soil even, the spacing of respectively getting between kind of the cup equates.

By way of ascent stage of seed-box the time, can get seed in order to make each get kind of cup reliably, the seeding unit of seeds having abnormal shape provided by the utility model, adopted following two kinds of measures: 1, respectively get kind of the size of cup open end with arrange the big or small corresponding of the seed broadcast, promptly only need broadcast a kind period of the day from 11 p.m. to 1 a.m when every cave, as potato, getting kind of the caliber size of cup openend will satisfy and can hold a seed, need broadcast two or more kinds period of the day from 11 p.m. to 1 a.m for every cave, the bore that then will be replaced with openend can hold kind of the cup of getting of two or more seeds; 2, when the little crop seed of hardness such as sowing potato etc., can on each gets the inner bottom surface of kind of cup, be connected with and stretch and ganoid pricker, the needle point of pricker is 0-2mm with getting kind of the distance of cup open end.

The course of work of the seeding unit of above-mentioned seeds having abnormal shape is: will pack in the seed-box such as seeds such as potatos earlier, the ascent stage of seeding chain in seed-box buried by seed, when drive sprocket rotates under the effect of input power, driving the seeding chain rotates synchronously, the ascent stage of seeding chain moves from bottom to top, kind of the cup of getting on this ascent stage just asks seed to move upward together, under the effect of thrust of getting kind of cup and seed self gravitation, the pricker needle point is pricked on the bottom surface of the seed that is held in the palm just, the seed that is held in the palm can not slipped out from getting kind of a cup in the process that rises, when moving to when changing the descending branch position over to by peak, under action of gravity, holder just breaks away from pricker at the seed of getting on kind of the cup, turn over and fall in the pipe of sowing, seed continues, from the port of export row of the pipe of sowing broadcasts the ditch that plough that the wedge angle position by this port of export constituted left soil in.Along with the continuous rotation of seeding chain, respectively get kind of cup just continuous in seed-box, take out seed, pipe is broadcast in the soil with the spacing in the rows row who equates through sowing.Cut off the input power of drive sprocket, seeding unit quits work.Increase and decrease is fixed in quantity of getting kind of cup on the seeding chain or the rotating speed of adjusting drive sprocket, can adjust the spacing in the rows of seed.

The seeding unit of seeds having abnormal shape provided by the utility model is that the row of the seed of circle or sub-circular broadcasts for shape, also is suitable for naturally.

Learn by above narration, the seeding unit of seeds having abnormal shape provided by the utility model, be applicable to that not only shape is that the row of the seed of circle or sub-circular broadcasts, and be applicable to that more shape is that the row of polyhedral seeds having abnormal broadcasts, use face width, highly versatile, the seeding unit that has solved other version requires difficult point harsh, bad adaptability to shape of the seed.
