Abstract
A rice seeder comprises a frame, a walking wheel arranged on a central shaft of the frame, a front rubbing board, a middle rubbing board, a rice seed hopper, a seeding control mechanism, a rear rubbing board, a seed metering switch, a pull rope and the like which are sequentially arranged on the frame from front to back. The seeding control mechanism adopts a cam structure, so that seeding can be automatically completed along with the advance of the seeding machine, and the three-stage rubbing plate structure completes slotting, seeding and covering at one time. The utility model discloses simple structure, convenient operation is practical.
Description
The utility model relates to rice seeder, belongs to agricultural tools.
In the prior art, the planting of paddy rice needs earlier seed rice premature rice, plays kind after sprouting for the treatment of grows up to little seedling, plants by rice transplanter or throwing transplanting machine that its operation is many, workload is big again; Rice transplanter, throwing transplanting machine cost height use maintenance all to need certain technical ability, so be generally used for extensive operation; Rice shoot is not embarked on journey behind the throwing transplanting machine rice transplanting, is not easy to peasant's management in the future.
The utility model aim to provide a kind of simple in structure, cost is low and can disposablely finish live rice seeder.
Technical solution of the present utility model is as follows:
The utility model comprises frame and is installed in road wheel on the frame axis, it is characterized in that: before and after it also comprises rack-mounted successively before rubbing board, middle rubbing board, seed rice bucket and sowing controlling organization, back rubbing board.
Described seed rice bucket and sowing controlling organization comprise the rack-mounted funnelform seed rice bucket that is, and its lower end is connected to a plurality of sowing pipes that are equally spaced; The sowing controlling organization is a cam mechanism, it comprises that one is installed on the frame and cam, follower lever, guide pin bushing that rotates with road wheel and the sowing switch that is connected with follower lever, described sowing switch is installed in the sowing pipe, it is converted into the reciprocating motion of follower lever by cam mechanism with the continuous rotation of road wheel, and drives the sowing switch that is connected and constantly open, close.
Rubbing board, middle rubbing board before described, back rubbing board bottom are concordant substantially, described in rubbing board bottom be distributed with a plurality of equidistant projectioies, its position is corresponding to the position of thereafter sowing pipe.
In the said structure, the structure of cam mechanism is various, can adopt tip follower disk cam structure, also can adopt mobile follower lever cylindrical cam structure, and this class formation is the common structure in the mechanical field, has not just elaborated at this.Certainly, the continuous rotation of road wheel is converted into the reciprocating motion of follower lever, and drive the sowing switch connected and constantly open, close, can also adopt other outer structures of cam structure, as the crank block structure in the planar linkage structure etc.
The course of work of the present utility model is as follows:
Tanaka to be sowed, along with advancing of sower, before rubbing board at first mud is drawn together flatly, middle rubbing board is drawn together out a plurality of mud grooves that are equally spaced by its following a plurality of projectioies that are equally spaced with mud subsequently and is waited until and sow, at this moment, rotation along with road wheel, the sowing switch opens, limited seed rice falls into the mud groove by the sowing pipe, and the sowing switch cuts out, back rubbing board is drawn together mud flat once more and is covered seed rice, thereby finishes the overall process of sowing.The road wheel certain distance of walking again, above-mentioned action is repeated, and so can finish the sowing work of embarking on journey anyhow quickly and easily and does not need manual action.
Further solution of the present utility model is to also have a kind of amount switch in the seed rice bucket, and it is positioned at funnel mouth place of sowing pipe sowing switch top, this switch is concentrated Artificial Control by a stay cord, as a master switch, it has the funnel mouth of adjusting size and closes lural function.
The utility model makes sowing to finish automatically with advancing of sower owing to adopt cam structure; Three grades of rubbing board structures then make fluting, sowing, lid plant and once finish.The utility model is simple in structure, easy to operate practicality.
Certainly, according to different sowing requirements, the concrete parameter of each parts is adjusted on the spacing that the quantity etc. of broadcasting seed rice all can be by the sowing pipe, the cam mechanism as the fore-and-aft clearance of seed rice, at every turn, certainly, road wheel also can drive cam by gear-driven mode and rotate, by changing this rotation ratio, the spacing of sowing also can change.
Below with reference to drawings and Examples the utility model is described further:
Accompanying drawing 2 is seed rice bucket among the utility model embodiment and the schematic diagram of sowing controlling organization;
Each sequence number is respectively in the accompanying drawing: 1, stay cord; 2, preceding rubbing board; 3, middle rubbing board; 4, frame; 5, road wheel; 6, back rubbing board; 7, seed rice bucket; 8, funnel mouth; 9, kind amount switch; 10, sowing switch; 11, guide pin bushing; 12, follower lever; 13, extension spring; 14, cam; 15, sowing pipe; 16, projection.
Shown in accompanying drawing 1,2, the utility model by frame (4) and be installed in road wheel (5), front and back on frame (4) axis rack-mounted successively before rubbing board (2), middle rubbing board (3), seed rice bucket (7) and sowing controlling organization, back rubbing board (6) and stay cord (1), kind amount switch (9) form.Rubbing board (2), middle rubbing board (3) before described, back rubbing board (6) bottom are concordant substantially, described in rubbing board (3) bottom be distributed with a plurality of equidistant projectioies (16), its position is corresponding to the position of thereafter sowing pipe (15).Seed rice bucket (7) is installed on the frame (4), is funnel-form, and its lower end is connected to a plurality of sowing pipes (15) that are equally spaced; The sowing controlling organization is a cam mechanism, it comprise one be installed on the frame axis and with cam (14), follower lever (12), guide pin bushing (11), the extension spring (13) of road wheel (5) coaxial rotation and the sowing switch that is connected with follower lever, described sowing switch (10) is installed in the sowing pipe (15), it is converted into the reciprocating motion of follower lever (12) by cam mechanism with the continuous rotation of road wheel (5), and drives the sowing switch (10) that is connected and constantly open, close; The funnel mouth (8) of sowing switch top locates to also have a kind of amount switch (9) in sowing pipe (15), and it is by stay cord (1) centralized Control, and it has the function that adjusting funnel mouth (8) is big or small and close funnel mouth (8).
Claims (2)
