Abstract
The utility model discloses a forward type profile modeling ground wheel transmission for seeder, including the land wheel, the profile modeling swing arm, driving sprocket and chain, two profile modeling swing arms with one end respectively the suit at the both ends of land axle, the other end articulates at the round pin of seeder forebay centre of symmetry both sides epaxially respectively, an end fixed mounting of land axle has the A sprocket, coaxial fixed mounting has B sprocket and C sprocket on the seeder forebay of A sprocket homonymy, tooth centre bit in the coplanar of A sprocket and B sprocket, B, the axial lead of C sprocket and the axial lead coincidence of round pin axle, a sprocket and B sprocket pass through chain drive, driven sprocket on C sprocket and seed metering ware or the fertilizer apparatus passes through chain drive. The utility model discloses because be leading preceding at the seeder, the land wheel walk uncultured solidly subaerial, is difficult for skidding, the power transmission makes seed metering, arranges the influence that fertile volume was not was not just fluctuate by on ground, can be evenly unchangeably. The device simple structure, use are reliably.
Description
Technical field
The utility model belongs to agricultural mechanical field, and what relate to is a kind of device relevant to sower, and what be specifically related to is a kind of front positioning type copy land wheel drive unit for sower.
Background technology
The type of drive of seeding apparatus of seeder, fertilizer apparatus has two kinds, and a kind of is driven by the power take-off of tractor, and another kind drives with copy land wheel drive unit.In front a kind of type of drive, because the gear change during the Power output rotating speed of tractor and tractor travel has nothing to do, when tractor changes gear change travel speed in seeding process, the variation relation of its Power output rotating speed and gait of march is nonlinear, so, with the seeding quantity of this type of drive, the travel speed with tractor is changed, even sowing can not be ensured.The seeding quantity of the second type of drive can not change with the gait of march change of tractor, but owing to being subject to the suspension space constraint between tractor and sower, current copy land wheel transmission mechanism all adopts rear-mounted driving, the rear of sower is placed in by copy land wheel drive unit, mainly there is following defect in this rear-mounted profiling ground actuation: one is that copy land wheel walking is on the ground sowed in seeding process, the seed broadcast can turn over to ground surface by the anti-skidding driving gear of land wheel again, affects it and germinates; Two is that copy land wheel is walked on the cultivated land face that the soil property of farming is loosened relatively, and land wheel easily skids and seeding quantity is changed.
Summary of the invention
The purpose of this utility model is to overcome the defect of existing rear-mounted profiling ground existing for actuation, proposes a kind of front positioning type copy land wheel drive unit for sower.
The technical scheme realizing above-mentioned purpose is: a kind of front positioning type copy land wheel drive unit for sower, comprise land wheel, profiling swing arm, drive sprocket and chain, the outer ring, both sides of land wheel is equipped with anti-skidding driving gear, profiling swing arm is identical two, same one end of two profiling swing arms is set in the two ends of land axle, it is characterized in that, the other end of described two profiling swing arms is hinged on the bearing pin that sower forebay symmetrical centre both sides support by bearing pin support plate respectively, one termination of land axle is installed with the A sprocket wheel in described drive sprocket, the sower forebay of A sprocket wheel homonymy is coaxially installed with a B sprocket wheel and C sprocket wheel, the tooth of A sprocket wheel and B sprocket wheel is centrally located at same plane, the axial line of the sprocket shaft of B sprocket wheel and C sprocket wheel overlaps with the axial line of described bearing pin, A sprocket wheel and B sprocket wheel pass through chain drive, driven sprocket on C sprocket wheel and seeding unit or fertilizer apparatus passes through chain drive.
Further, be fixedly installed a cleaning shoe assembly between described two profiling swing arms, the termination of cleaning shoe abuts with the periphery in land wheel centre position.
The utility model is due to preposition before sower, and land wheel walking, on uncultured hard ground, is not easily skidded, and it also avoid land wheel to the impact sowing son; Transmission of power makes seeding, defertilizing amount not by the impact that ground height rises and falls, can be evenly constant.This apparatus structure is simple, use is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is vertical view embodiment illustrated in fig. 1.
In figure: 1. sower forebay, 2. sprocket shaft support plate, 3.C sprocket wheel, 4. sprocket shaft, 5. cleaning shoe assembly, 501. scrape mud version, 6. profiling swing arm, 7. anti-skidding driving gear, 8. land wheel, 9. land axle, 10.A sprocket wheel; 11. bearing pin support plates, 12. bearing pins, 13.B sprocket wheel.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the utility model comprises land wheel 8, profiling swing arm 6, drive sprocket and chain, the outer ring, both sides of land wheel 8 is equipped with anti-skidding driving gear 7, profiling swing arm 6 is identical two, same one end of two profiling swing arms 6 is set in the two ends of land axle 9, the other end of two profiling swing arms 6 is hinged on the bearing pin 12 that supported by bearing pin support plate 11 respectively, bearing pin support plate 11 has four, be divided into two groups of symmetrical symmetrical centre both sides being fixedly installed on sower forebay 1, one termination of land axle 9 is installed with A sprocket wheel 10, A sprocket wheel 10 is positioned at the outside of profiling swing arm 6, the sower forebay 1 of A sprocket wheel 10 homonymy is fixedly installed one group of sprocket shaft support plate 2, a rotating sprocket shaft 4 sprocket shaft support plate 2 is equipped with, sprocket shaft 4 is coaxially installed with a B sprocket wheel 13 and C sprocket wheel 3, the tooth of A sprocket wheel and B sprocket wheel is centrally located at same plane, the axial line of sprocket shaft 4 overlaps with the axial line of two bearing pins 12, A sprocket wheel 10 and B sprocket wheel 13 pass through chain drive, C sprocket wheel 3 passes through chain drive with the driven sprocket on external equipment seeding unit or fertilizer apparatus.
In the course of work, when sower move ahead promote land wheel 8 rotate time, A sprocket wheel 10 on land axle 9 will be rotated by chain-driving B sprocket wheel 13, and B sprocket wheel 13 drives C sprocket wheel 3 to rotate by sprocket shaft 4, and power can be transferred on seeding unit and fertilizer apparatus by chain by C sprocket wheel 3 again.When ground height rises and falls, land wheel 8 will swing up and down around bearing pin 12 with profiling swing arm 6, because the axial line of sprocket shaft 4 and the axial line of two bearing pins 12 overlap, so the centre-to-centre spacing between A sprocket wheel 10 and B sprocket wheel 13 can not change, the power transmission of chain can not be affected, also can not affect the rotating speed of sprocket shaft 4, its transmission of power makes seeding, defertilizing amount not by the impact that ground height rises and falls, can be evenly constant.
In the present embodiment, a cleaning shoe assembly 5 is also fixed with between two profiling swing arms 6, cleaning shoe 501 is between the anti-skidding driving gear 7 at land wheel 8 two ends, and the termination of cleaning shoe 501 abuts with the periphery in land wheel 8 centre position, and gap is left in the inner side of both sides and anti-skidding driving gear 7.Between the anti-skidding driving gear 7 of two rows during sticky stifled earth, cleaning shoe 5 can be wiped off, ensures that land wheel 8 is normally walked.
