Description

A kind of seed feeding method

Technical field

The present invention relates to agricultural seeder machinery field, particularly relate to a kind of seed feeding method.

Background

The planting patterns of tradition seeding operation, needs to consume substantial amounts of energy.Precise sowing becomes the planting patterns of a kind of advanced person, Have saving seed, reduce thinning workload, the remarkable advantage such as increase production and improve productivity.The major way of precise sowing operation at present is gas Power formula, mechanical type, Electromagnetically vibrating etc..Pneumatic precision seeder utilizes negative pressure generator to produce negative-pressure adsorption seed, to kind The shape requirement of son is not strict, and seeding precision is high, but complete machine structure is complicated, and manufacturing cost and the technology of use require higher and pore The most blocked；Mechanical precise seeder utilizes the form such as pocket, type hole to carry out seeding, simple in construction, but seeding precision is low, broadcasts The form of kind is more single, has a wound kind phenomenon, and in irregular shape or that granule is less seed is difficult to precision metering device；Electricity Magnetic vibration formula precise seeder utilizes electric and magnetic oscillation to sort seed, the oscillating plate of solenoid actuated seeder vibrate, from vibration What box flowed out plant grain moves along the trapezoidal groove set by discharge plate, and uniformly moves forward and fall in seed spout, then by seed spout Importing in cavities, this seeding mode adapts to variously-shaped seed, but single grain fine sowing rate is low, and replay rate is higher, the suitableeest Together in drilling.

Complicated for Pneumatic type seeder structure, cost high, pore easily blocks and mechanical type seeder precision is low, easily hinder The shortcomings such as kind, Chinese patent ZL02138075.9 proposes magnetic-attraction precision sowing principle, and this seeding principle is with column electric magnet For magnetic force seeding element, utilize electromagnet suction to draw magnetic powder capsuled seed, lead to by controlling electric magnet solenoid current Disconnected, it is achieved filling of seeder is planted and seeding；Chinese patent ZL02263559.9 discloses a kind of swing type spacing seed feeder, but This swing type feed mechanism reciprocating motion inertia is big, magnetic head takes kind of a poor stability, inefficiency；For swing type feed mechanism Shortcoming, Chinese patent ZL200520075650 discloses again a kind of magnetic drum type precision seeding apparatus, mainly by cylinder, magnetic Head, conveyer belt, kind case, collecting ring, travel switch etc. form, and it is technically characterized in that multiple rows of magnetic head is arranged on drum shaft also Pressing single direction with cylinder to rotate, install multiple travel switch on the outer wall of cylinder side, each travel switch controls row's magnetic The break-make of head coil electric current, it is achieved the continuous seeding of cylinder single direction rotation, sowing；Chinese patent ZL200910029443.2 discloses A kind of permanent-magnet magnetic-attraction precision seeder, this device changes the electric magnet in magnetic drum seeder into permanent magnet, is accompanied by convex Wheeled pressure seed dresser structure, overcomes the electrical system complexity that electromagnetic type seeder exists, and seeding element volume is big, easy heating etc. Shortcoming.Although permanent magnet magnetic drum-type seeder overcomes the some drawbacks of electromagnetic cylinder formula seeder, but still at seed dresser Structure is complicated, not convenient for installation and adjustment in cylinder of seeding element, the shortcomings such as single continuous seeding is inefficient.Above-mentioned sowing Because all there is respective shortcoming and defect in device, the use that have impact on them is promoted.

Summary of the invention

It is desirable to provide a kind of seed feeding method, simplify seeding element mounting structure and plant clearly mode, it is achieved once filling Kind, whole dish is sowed, to improve sowing efficiency.

The present invention solves the scheme that its technical problem is used: a kind of seed feeding method, and it comprises the following steps: seeder Seed board 8 swings back and forth as gap around rotary shaft 1, plants case 6 and moves back and forth as gap along guide rod 3, and seed board 8 is minimum from level Inverse position hour hands turn to Far Left, plant case 6 simultaneously and move to extreme higher position from bottommost, after seed board 8 arrives leftmost position Stopping gap motionless, plant case 6 and then move down at once from extreme higher position, magnetic head (9) draws magnetic powder capsuled seed 19, then plants case 6 and exists It is motionless that seed board 8 extreme lower position stops gap, and seed board 8 is rocked to the right horizontal level from leftmost position；When seed board 8 is from the most left When position, limit is rocked to horizontal level, 4 push rod 15 tops on hole tray support 12 and 4 fore-sets 16 on magnetic head installation plate 7 Bottom surface contacts, and fore-set 16 oppressed by push rod 15 simultaneously, and fore-set 16 drives magnetic head installation plate 7 to overcome the pressure of stage clip 14 upwards to move Dynamic, magnetic head 9 plants clearly indentation in hole 23 from seed board 8, and magnetic powder capsuled seed 19 falls into the cave of hole tray 11 in self gravitation effect Kong Zhong, it is achieved force seeding and to bunch planting kind；Seed board 8 completes after planting at horizontal level, at once from horizontal level to left swing Dynamic, push rod 15 departs from fore-set 16, and magnetic head installation plate 7 oppressed by the stage clip 14 on magnetic head installation plate 7, and magnetic head installation plate 7 drives magnetic head 9 Put in again in the clear kind hole 23 on seed board 8 and fore-set installing hole 21 with fore-set 16, carry out filling next time and plant and seeding.

The method of the present invention is applicable not only to vegetable, the precise sowing needs of the little grain seed of flowers class, also can meet oil The precise sowing requirement of the crop such as dish, Oryza sativa L..Owing to have employed ferromagnetism object seeding, not only increase the magnetic attraction of magnetic head, Correspondingly reduce iron content needed for seed magnetic powder coating, and reduce seeding element physical dimension；And simple in construction, peace Dress is convenient, simultaneously by controlling the relative motion between seed board and magnetic head installation plate, conveniently realized magnetic head put in suction kind, The function of indentation seeding.
