Description
Technical field
The present invention relates to a kind of sower operation pressure kind of device, belong to agricultural mechanical field.
Background technology
Sow most important as agricultural production, the most basic production link, the germination and emergence of its operation quality on crops has important impact.Traditionally in order to ensure the uniformity of sowing depth and suppression intensity; it is all the uniformity adopting the structure adding feeler mechanism to ensure sowing depth; but facts have proved that even if ditching depth is consistent; but the spring due to seed causes seeds fall point to there is very large randomness; in addition the impact of follow-up earthing amount; be difficult to the coherence request ensureing sowing depth, this problem is more outstanding for the conservation tillage of current implementation.Secondly, because seed implantation exists spring impact, so be also difficult to ensure seed and the contact of planting bed wet soil, and then the germination affecting seed and the uniformity come up.For this reason, strengthen sowing depth uniformity and guarantee that the technical research that seed contacts with kind bed wet soil just seems extremely important.
Summary of the invention
The present invention is directed to sower operation process, to there is sowing depth inconsistent with suppression intensity and be difficult to ensure seed and the practical problem of planting bed wet soil and contact, develops that can to realize kind of a bed compacting, sowing depth consistent and guarantee the sower operation seed pressing wheel device of seed and kind bed wet soil close contact.The technical scheme realizing foregoing invention is as follows:
A kind of sower seed pressing wheel device, comprising: the parts such as plough, front bearing pin, spring, plough column, frame, spacer pin, jointed shaft, pull bar, rear pin shaft, seed pressing wheel, covering device and press wheel.It is characterized in that: seed pressing wheel is positioned at the rear portion of plough, the front portion of covering device, its front portion exceedes plough afterbody 3 ~ 5cm.Seed pressing wheel is clamped and connected by pull bar, and pull bar top is hinged by jointed shaft and frame.Plough passes through plough column together with welding machine frame; Frame is provided with spacer pin, and spacer pin is positioned at the position to the rear, bottom of jointed shaft.Be provided with rear pin shaft in the middle part of pull bar, plough column bottom is provided with front bearing pin, and spring front portion is articulated on front bearing pin, and rear portion is articulated on rear pin shaft, and pull bar is tightly pressed on spacer pin.Covering device and press wheel are positioned at the rear portion of seed pressing wheel successively, link together with frame.
Described sower seed pressing wheel device, seed pressing wheel is taken turns by low inflation and depth stop annulus forms, and depth stop annulus is welded on the both sides of low inflation wheel, and wherein depth stop circle diameter is compared with the little 6 ~ 8cm of low inflation wheel diameter.
Described sower seed pressing wheel device, is characterized in that the afterbody of plough is provided with trapezoidal window.
Compared with prior art, its advantage is in the present invention:
Seed can be pressed in the plane of distance earth's surface 3 ~ 4cm by the seed pressing wheel 1, with depth stop annulus, thus the spring of elimination seed causes the randomness of seed level, guarantees the uniformity of seed planting depth.
2, the pull bar of this seed pressing wheel is tightly pulled on spacer pin by spring, can compacting kind bed, ensures the compactness of kind of bed, plants the unsettled of root after preventing seed sprouting.
3, plough afterbody is provided with the native window of trapezoidal leakage, coordinates seed pressing wheel following closely, can ensure seed and direct contact of planting bed wet soil, is conducive to the germination rate ensureing seed.
Accompanying drawing explanation
Fig. 1 sower seed pressing wheel device schematic diagram
Fig. 2 sower seed pressing wheel structural representation
In figure: 1 plough, bearing pin before 2,3 springs, 4 plough columns, 5 frames, 6 spacer pins, 7 jointed shafts, 8 pull bars, 9 rear pin shafts, 10 seed pressing wheels, 11 covering device 12 press wheels, 13 low inflation wheels, the trapezoidal window of 14 depth stop annulus 15
Embodiment
In the embodiment shown in Fig. 1 ~ 2, plough 1 is welded in frame 5 by plough column 4, and before plough column 4 bottom is provided with bearing pin 2, and plough 1 afterbody is provided with trapezoidal window 15; Covering device 11 and press wheel 12 are connected to the rear portion of frame 5 in turn; Seed pressing wheel 10 is between plough 1 and covering device 11, and its front portion exceedes plough 1 afterbody 3 ~ 5cm, is clamped and connected together by 2 pull bars 8; Jointed shaft 7 in pull bar 8 top and frame 5 is hinged, and its underpart is provided with rear pin shaft 9; The anterior hanger of spring 3 on plough column 4 before bearing pin 2 place, rear portion is articulated in rear pin shaft 9 place on pull bar 8, pull bar 8 is tightly pressed in be positioned on the spacer pin 6 in frame 5; Seed pressing wheel 10 is made up of low inflation wheel 13 and depth stop annulus 14.During work, first output kind of a ditch by plough 1 on earth's surface, after seed drops on the kind ditch that plough 1 outputs at random, by seed pressing wheel 10, seed is tightly pressed on kind of bed, achieve seed and the close contact of planting bed wet soil.In this process, due to the effect of depth stop annulus on seed pressing wheel 10, ensure that the uniformity of seed planting depth; Then to be bled wet soil by the trapezoidal window 15 at plough 1 rear portion, realize seed upper and lower surface all surround by wet soil, ensure that the germination rate of seed.Because seed pressing wheel 10 is a low inflation wheel 13, so the distortion taking turns 13 outer surfaces along with low inflation can remove the clay on its surface; Complete earthing by the covering device 11 being positioned at seed pressing wheel 10 rear portion subsequently, press wheel 12 completes the secondary suppression to planting band after earthing, completes whole seeding process.
