Abstract

The utility model provides a seeding rate adjustable type cell wheel seeding apparatus and relates to a seeding apparatus for a planter. The problem of inequity in the seeding rate for seeds of different sizes is existed in the existing seeding apparatus, the waste and deficiency of seeds can easily occur, and the empty cavity can be caused and the seeding quality is affected. The utility model comprises a rack (4), a seed ejecting plate (12) and a seeding roller (1) connected with the rack (4), a through cavity (1-1) provided on the seeding roller (1). A shaft pin (2) is provided inside the through cavity (1-1). A spring (3) is arranged between a base (2-1) of the shaft pin (2) and an inner bottom surface of the seeding roller (1). The utility model also comprises an eccentric shaft (5). The eccentric shaft (5) is connected with the rack (4) through a bearing (6). The end of the eccentric shaft (5) is fixedly connected with an adjusting hand wheel (7). The base (2-1) of the shaft pin (2) contacts with the shaft plane of the eccentric shaft (5). The utility model can achieve adjustment of sizes of different seed-filling cavities for seeds of different granular diameters, realize the need for different seeding rates, and meanwhile reduce the rate of the empty cavity and improve the seed-filling effect.

Description

The adjustable nest eye wheel of seeding quantity seeding unit

Technical field: the utility model relates to the seeding unit that uses on a kind of sower.

Background technology: the nest eye on the existing seeding unit is a fixed groove, though it can be sowed, but because nest eye volume is fixed, the problem of seed for different volumes with regard to existing seeding quantity not wait, seed waste and seed deficiency take place easily, and can only make the degree of depth of nest eye very shallow in order to adapt to seeding quantity, like this when filling kind with regard to seed is jumped out outside the nest eye and cause the hole, thereby influence seeding quality.

The utility model content: the purpose of this utility model is to provide the adjustable nest eye wheel of a kind of seeding quantity seeding unit, it has solved in the past, and seeding unit fills the problem of planting too much and filling kind of deficiency, that can realize fills kind of an effect, avoided the generation of hole rate, it comprises frame 4, seeds scraper 12 that is connected with frame 4 and seeding roller 1, be arranged on the cavity 1-1 on the seeding roller 1, in cavity 1-1, be provided with pin 2, between the inner bottom surface of the base 2-1 of pin 2 and seeding roller 1, spring 3 is housed, it also comprises eccentric shaft 5, described eccentric shaft 5 is connected by bearing 6 with frame 4, be connected with adjustment handwheel 7 in the end of eccentric shaft 5, the base 2-1 of described pin 2 contacts with the axial plane of eccentric shaft 5.The utility model can realize filling the not isometric variation in kind of cave by adjusting eccentric handwheel, thereby can conveniently realize the needs of different volumes planting seed, be provided with dead axle in the outside of eccentric shaft and adjust piece, when level and smooth the moving to when adjusting the piece position of pin along dead axle, promptly can appearance kind of a cave volume be reduced owing to pin is adjusted piece jack-up, unnecessary seed is ejected outside the cave, make and fill kind of quantity and more unnecessary seed is extruded outside the cave more than the quantity of needs sowings, just avoided the generation of hole rate, simultaneously it also avoided pin in motion process to the wearing and tearing of eccentric shaft, improved the service life of machine.The utility model is simple in structure, and easy operating is beneficial to and applies.

Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the I place enlarged drawing of Fig. 2, and Fig. 4 is the structural representation of embodiment two, and Fig. 5 is the B-B cutaway view of Fig. 4, and Fig. 6 is the K place enlarged drawing of Fig. 4.

Embodiment one: with reference to Fig. 1, Fig. 2 and Fig. 3, present embodiment comprises frame 4, the seeds scraper 12 that is connected with frame 4 and seeding roller 1, is arranged on the cavity 1-1 on the seeding roller 1, in cavity 1-1, be provided with pin 2, between the inner bottom surface of the base 2-1 of pin 2 and seeding roller 1, spring 3 is housed, it also comprises eccentric shaft 5, described eccentric shaft 5 is connected by bearing 6 with frame 4, be connected with adjustment handwheel 7 in the end of eccentric shaft 5, the base 2-1 of described pin 2 contacts with the axial plane of eccentric shaft 5.

Its operation principle is as follows: by adjusting handwheel 7, can drive eccentric shaft 5 rotations, under the effect of spring 3, pin 2 keeps the contact condition of bottom surface and eccentric shaft 5 always, so lengthwise movement that when eccentric shaft 5 rotations, pin 2 is done with respect to cavity 1-1, thereby appearance kind cave 13 volumes that form between the upper end of the upper end of pin 2 and cavity 1-1 are changed, difference according to sowing seed footpath size is adjusted eccentric shaft 5, just can reach to adjust volume that holds kind of cave 13 and then the purpose of adjusting seeding quantity.

Embodiment two: with reference to Fig. 4 and Fig. 5, present embodiment also comprises adjusts piece 8 and dead axle 9, described adjustment piece 8 is arranged between the base 2-1 and eccentric shaft 5 of pin 2 in the vertical, adjusting piece 8 is arranged in the groove 9-1 of dead axle 9 in the horizontal, the longitudinal section height of adjusting piece 8 is higher than dead axle 9, the position of adjusting piece 8 is arranged on the place that adapts, position with seeds scraper 12, described dead axle 9 and frame 4 Joints, between dead axle 9 and eccentric shaft 5, bearing 10 is housed, between dead axle 9 and seeding roller 1, bearing 11 is housed.

Its operation principle is as follows: drive the capacity that vertically moving of piece 8 and pin 2 adjusted the required appearance kind of sowing cave of adjusting by adjusting eccentric shaft 5, plant case 15 and in holding kind of cave 13, fill kind, seeding roller 1 rotates pin 2 is smoothly rotated around dead axle 9, vertically highly be higher than dead axle 9 owing to adjust piece 8, when pin 2 forwards the position of adjusting piece 8 to and slide on the adjustment piece 8, the volume that holds kind of cave 13 diminishes, unnecessary seed in appearance kind of the cave is extruded outside the cave, the utility model is by filling seed more and then unnecessary seed being extruded way outside the cave in holding kind of cave, well avoided seed to jump out outside the cave and the hole situation that takes place, reduce hole rate, improved seeding quality.
