Abstract
An inside-filling hole-type seeding apparatus can conveniently adjust the seeding rate, whose structure is to connect coaxial fixed ring from the disc on side of seeding apparatus. The fixed ring is provided with a chute, and the chute is internally installed with a rotating ring restricted by the chute. The rotating ring is unable to make axial and radial movement in three-dimensional space, and only rotate peripherally surrounding the fixed ring. The rotating ring is arranged with guide channels corresponding to each groove on the seeding apparatus. The guide channels extend following certain track, and can control certain internal wall of groove for moving in its track. For adjustment, the rotating ring rotates, and each guide channel on the rotating channel controls the activity of internal wall in each groove and changes the groove volume so that the seeding rate is adjusted.
Description
Technical field
The utility model relates to agricultural machinery, is a kind of sowing mechanism of sower, can solve the problem that traditional internal-charging hole-type seeding unit is adjusted the seeding quantity inconvenience, and is not strict to the shape and size requirement of seed.
Background technology
Traditional internal-charging hole-type seeding unit is an adjusting type hole dimension one by one when transferring seeding quantity, and is not only time-consuming but also can not guarantee various hole dimension unanimity, and adjusting range is limited.
Summary of the invention
The utility model provides a kind of type hole dimension inter charging bore type seed sowing device easy to adjust, and each seeding unit only need be adjusted the size that all models hole on the seeding unit just can be adjusted in a place.Its objective is such realization: on the side end cap of traditional internal-charging hole-type seeding unit, connect a ring coaxial with seeding unit, be called and decide ring, fixed ring is fixed with respect to seeding unit, and slideway is arranged above; Between slideway, connect a ring, be called rotating ring, rotating ring with encircle surely coaxial, in three dimensions, rotating ring axially and radially retrained by slideway, and can only do circumferentially rotation around fixed ring; Certain inwall in each type hole of seeding unit is a mobilizable adjustable plate, and the activity of adjustable plate can change type hole dimension; Be distributed with the guide groove that extends by certain track above the fixed ring, guide groove quantity is identical with seeding type hole number, and corresponding one by one, and guide groove contacts with the adjustable plate in various hole, the control of the active receiving guide groove of adjustable plate.When adjusting seeding quantity, rotating ring rotates around fixed ring, and the adjustable plate in various hole is subjected to the control of rotating ring guide groove and activity, thereby changes various hole dimension, has realized the amount of broadcasting adjustment.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof
Fig. 1: embodiment 1
Fig. 2: embodiment 2
Among the figure: 1. seeding unit side end cap 2. encircles 3. rotating rings, 4. adjustable plate axles, 5. adjustable plates, 6. control pins, 7. type holes, 8. guide grooves surely
Embodiment
In embodiment shown in Figure 11: on seeding unit side end cap 1, connect one with seeding unit coaxial decide ring 2, from encircling section surely, it is thick to encircle thin and interior week of periphery surely, encircles 2 so surely and contacts the back with seeding unit side end cap 1 and form the groove slideway in its outer; Rotating ring 3 is connected in the slideway, limited by slideway, and rotating ring 3 can not can only be done circumferentially to rotate axially with radially movable around encircling 2 surely; The roof in seeding type hole 7 is the adjustable plates 5 of 4 swings around the shaft, and adjustable plate outwards pendulum type hole 7 enlarges, and dwindles to the inner hole; Be distributed with on the rotating ring and type hole guide groove 8 one to one, the guide groove profile is an arc, the guide groove direction along rotating ring circumferentially and radially two directions extend, axially measure along rotating ring, the distance in the guide groove centre-to-centre spacing rotating ring center of circle progressively increases (or dwindling); A control pin 6 parallel with rotating shaft 4 is arranged on the adjustable plate 5, and control pin one end is in guide groove 8, and the sidewall of guide groove has limited control pin scope of activities.Rotating ring 3 rotates around encircling 2 surely during work, guide groove 8 control and regulation plates 5 activities on the rotating ring, and type hole 7 sizes change thereupon.
In embodiment shown in Figure 22: a sidewall in type hole 7 is energy adjustable plates 5 along the axial activity of seeding unit, and when adjustable plate stretched to the type hole, the type hole dimension reduced, otherwise increases; Be distributed with on the rotating ring and type hole guide groove 8 one to one, along circumferentially extending, it is coaxial with rotating ring to extend track along rotating ring 3 for guide groove, and from axially cutting guide groove open, measuring its section is wedge-like along guide groove extension track; An end face of adjustable plate 5 contacts with the guide groove inclined-plane.Rotating ring 3 rotates around encircling 2 surely during work, and the guide groove 8 on the rotating ring promotes adjustable plate 5 activities, and type hole 7 sizes change thereupon.
In embodiment illustrated in figures 1 and 2: for ease of grasping adjustment amount, on rotating ring, be provided with scale or benchmark, on fixed ring, be provided with benchmark or scale.
Claims (4)
1. adjustable inter charging bore type seed sowing device, certain inwall in formation type hole (7) be one can be movable adjustable plate (5), it is characterized in that: go up to connect at seeding unit side end cap (1) and decide ring (2), on the fixed ring slideway is arranged, connect rotating ring between slideway, slideway restriction rotating ring is axial and radially movable, can only circumferentially rotate, be distributed with the guide groove (8) that extends by certain track on rotating ring, the adjustable plate (5) in each type hole of each guide groove and seeding unit contacts, the control of the active receiving guide groove of adjustable plate.
2. seeding unit according to claim 1 is characterized in that: the rotating ring guide groove radially and circumferentially extends, and circumferentially measures along rotating ring, and the distance in the guide groove centre-to-centre spacing rotating ring center of circle progressively increases or dwindles.
3. seeding unit according to claim 1 is characterized in that: the rotating ring guide groove circumferentially extends along rotating ring, and it is coaxial with rotating ring to extend track, extends track from axially cutting guide groove open along guide groove, and measuring its section is wedge-like.
4. seeding unit according to claim 1 is characterized in that: be provided with scale or benchmark on rotating ring, be provided with benchmark or scale on fixed ring.
