Description

Combined seed and fertilizer drill

The utility model belongs to a kind of farm machinery that are used for dry land fertilising, seeding operation in the agricultural machinery.

Combined seed and fertilizer drill is a most widely used agricultural tool in the present agricultural production, and its model, kind are extremely many.Yet, the seeding-apparatus assembly and the fertilizer applicator assembly basic structure of existing various mechanical combined seed and fertilizer drill key operation parts are similar, mostly seed plate in the seeding-apparatus assembly is internal filling type, fills the horizontal garden dish, inclination garden dish, vertical garden dish or the like of forms such as formula or bucket wheel formula outward, its operation when using all be again with gyration fill kind as finishing, the basic exercise form of seeding, majority also is provided with rigidity seed dresser structure, very easily cause kind of a grain damage (being commonly called as the gram seed), influenced the seeding operation quality; Design hairbrush class seed dresser structure on some facility, but because hairbrush is easy to wear, the life-span is poor; The same result of use that influences.After particularly vernalization sowing agronomic technique occurred, the mechanical seeding unit of existing majority can not be born the sowing requirement of vernalization kind grain, has postponed the popularization of advanced agronomic technique; Still outer groove wheel fertilizer distributors of continuing to use in the fertilizer applicator assembly when using the chemical fertilizer of the easy moisture absorptions such as two ammonium classes, because the chemical fertilizer deliquescence becomes piece more, chemical fertilizer built on stilts, clogging in fertilizer apparatus appear, chemical fertilizer row do not go down, and the fertilizer quality is reduced, and has a strong impact on crop yield.

The purpose of this utility model is exactly the technical problem that exists at above-mentioned prior art, design provides a kind of combined seed and fertilizer drill that is made of Novel seeder assembly and fertilizer applicator assembly, by adopt by toggle drive move reciprocatingly get seeding bar structure finish the seeding operation, by fertilizer poking plugger and Fei Men, contact lever, take off the land wheel assembly structure and finish the fertilising operation, reach and reduce gram seed rate, improve sowing and fertilising quality, satisfy and purpose that the sowing of adaptation vernalization seed requires.

Basic design of the present utility model is, combined seed and fertilizer drill comprises seeding-apparatus assembly and fertilizer applicator assembly, its seeding-apparatus assembly by kind of a case, every kind of a plate, stage clip fixed stop fork and be assemblied in kind of the case chamber and moving up and down get to keep off fork, stage clip, elasticity retaining kind of device on seeding bar, lead, the compression spring axis and be configured in kind of seeding slideway, connecting rod, crank, driving shaft, the friction driving roller of case seeding one side form; The fertilizer applicator assembly is by fertile case and is configured in support, extension spring, the fertilizer poking plugger in the fertile case and is configured in that fertile lower box part is used to close or open contact lever that the fertile door of fertile door, control of defertilizing opening opens and closes, takes off land wheel, field digging wheel claw constitutes.

The utility model can not only satisfy the machine sowing needs of vernalization kind, and when fertilising built on stilts, do not stop up, have simple in structure, adjust easy to use, seeding operation gram seed rate is low, applicability wide, the characteristics of sowing and apply fertilizer quality height, reliable operation.

Fig. 2 is the fertilizer applicator assembly structure schematic diagram of combined seed and fertilizer drill;

Piece number explanation among the figure:

1. seeding slideway 2. elasticity retainings kind of device 3. fertile case 4. supports 5. extension springs 6. fertilizer poking pluggers 7. fertile door 8. hinges 9. contact levers 10. are taken off land wheel 11. field digging wheel claws 12. stage clips 13. leads 14. stage clip fixed stop and are pitched on 15. compression spring axis retaining fork 16. and get 24. kinds of grain outlets of seeding bar every 17. kinds of casees of kind of plate, 18. friction driving rollers, 19. driving shafts, 20. tractor driving wheels, 21. connecting rods, 22. cranks 23.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Combined seed and fertilizer drill comprises seeding-apparatus assembly and fertilizer applicator assembly: A. is in seeding-apparatus assembly, the upper end of getting seeding bar 23 disposes fixing and is set with elasticity retaining kind of a device 2, the lead 13 of stage clip 12, by retaining fork on the compression spring axis 15 stage clip 12 upper ends are located on lead 13, the lower end of stage clip 12 is connected with elasticity retaining kind of a device 2, and elasticity retaining kind of a device 2 can slide up and down along lead 13, to be equipped with elasticity retaining kind of device 2, the seeding bar 23 of getting of retaining fork 15 is packed in kind of the case 17 on stage clip 12 and the compression spring axis, its lead 13 cooperates with the prong of the stage clip fixed stop fork 14 on kind of plate 16 in being fixed on kind of case 17, and this prong size is pitched 15 appearance and size less than retaining on the compression spring axis; Seeding slideway 1 is configured in kind of case 17 1 sides, and its upper end is provided with kind of a grain outlet 24; The two ends of connecting rod 21 are divided and are got seeding bar 23 and crank 22 is hinged, and driving shaft 19 1 ends are fixedlyed connected with crank 22, and friction driving roller 18 is fixed on the driving shaft 19, and contacts with tractor driving wheel 20, the formation seeding-apparatus assembly.B. in the fertilizer applicator assembly, support 4 is packed in fertile case 3 chambeies, in the extension spring 5, following two ends are connected with fertilizer poking plugger 6 with support 4 respectively, on the lower surface of fertilizer poking plugger 6, fixing fertile door 7, utilize the pulling force of extension spring 5 to make fertile door 7 be close to place, fertile case 3 lower surfaces, and with its defertilizing opening sealing, one end of fertile door 7 and contact lever 9 overlaps on the hinge 8 of packing into successively, and become the angle shape to fix at the circumferential and axial of hinge 8, the side-lower that land wheel 10 is installed in kind of case 3 of taking off that has field digging wheel claw 11, and field digging wheel claw 11 can contact cooperation with contact lever 9 in the rotation, forces contact lever 9 to turn an angle around hinge 8 with fertile 7, constitutes the fertilizer applicator assembly.The upper end of getting seeding bar 23 is pointed asymmetricly ridge structure.

During operation, rotatablely moving of tractor driving wheel 20 relies on frictional force that friction driving roller 18 is rotated, and makes by driving shaft 19, crank 22, connecting rod 21 and gets seeding bar 23 and pump in kind of case 17, gets seeding bar 23 and moves downward kind of the work of getting of finishing; After getting kind, moving up to elasticity keeps off when planting device 2, get seeding bar 23 and plant that grain promotes elasticity retaining kind of a device 2, stage clip 12 moves upward synchronously, when stage clip 12 be fixed stage clip retaining fork 14 spacing after, stage clip 12 is compressed, and elasticity retaining kind of a device 2 will be planted an outlet 24 to get out of the way, and gets the kind grain of seeding bar 23 upper ends and broadcasts the soil through seeding slideway 1 from kind of a grain outlet 24, back and forth carry out, finish seeding operation.Taking off land wheel 10 travels forward with tractor and rotates, continuously stirring contact lever 9 by field digging wheel claw 11 is the center swing with hinge 8, and drives fertile door 7 swings, under the pulling of extension spring 5 and fertilizer poking plugger 6, fertile door 7 carries out opening and closing of fertile case 3 lower end defertilizing openings continuously, finishes the fertilising operation.Moving up and down of fertilizer poking plugger 6 has mandatory fertilizer function, and the swing of fertile door 7 has the vibration effect, can improve fertilization effect.
