Abstract
The utility model discloses a seeder depth wheel comprising a wheel hub, a rubber tire, and a bearing. The rubber tire is fixedly disposed on the outer ring of the wheel hub, and the bearing is fixedly disposed on the center of the wheel hub. The wheel hub is formed by fixedly connecting two hub bodies in a back-to-back manner. The middle part of each of the hub bodies is uniformly provided with three sector-shaped waist holes around the center, and the center of each of the hub bodies is provided with a groove in an outwardly-stretched manner. The bearing is disposed in the grooves of the back-to-back hub bodies, and the outer ring of the bearing is fixedly provided with a sealing ring. Two sides of the bearing contacted with the hub bodies are fixedly provided with dustproof rings. The hub bodies adopt the integrated stretching design, and the dynamic balance performance, the axial bouncing performance, and the radial bouncing performance of the hub bodies can tend to stable, and in addition, the sealing ring and the dustproof rings are disposed between the bearing and the hub bodies, and therefore the service lifetime of the product can be prolonged. By adopting the design of the waist holes, the dirt can be easily removed from the wheel hub, and the cleaning times of the hub bodies can be reduced, and the load of the engine can be reduced.
Description
Technical field
The novel a kind of sower accessory field that relates to of this use, relates in particular to a kind of sower gauge wheel.
Background technology
At present, the sower gauge wheel of widespread use on market, a kind of is to adopt full-closed structure, by a slice plastics hub, a slice iron hub, rubber tire and bearing are formed by connecting by screw and nut.Another kind of by steel ring, spoke, bearing seat, rubber tire and bearing are formed by connecting by bolt and nut.Sower gauge wheel adopts above-mentioned two kinds of structures, often there will be in actual use following problem, and encountering the hard things such as stone can break as plastics hub, and plastics hub can be aging.Earth easily enters into wheel the inside, is bonded on iron tyre hub, is not easy to remove, and causes engine load to increase.Wheel hub has multiple parts to combine, complex structure, and assembly clearance is large, causes that wheel is axial, radial runout is large, and when rotation, kinetic balance effect is bad.In addition, in the direct stationary hub of bearing, sealing effectiveness is bad, and earth or the water capacity easily enter into bearing the inside, damages bearing, these problems affect sower work efficiency and increased maintenance cost.
Utility model content
For solve sower gauge wheel exist, easily aging, break, kinetic balance is bad, sealing effectiveness is bad, affect sower work efficiency and increase maintenance cost problem, the utility model provides the sower gauge wheel of another kind of mode.
To achieve these goals, the technical solution adopted in the utility model is: a kind of sower gauge wheel, comprise wheel hub, rubber tire and bearing, and described rubber tire is fixed on the outer ring of wheel hub, and bearing is fixed on the circle centre position of wheel hub; Described wheel hub by two hubs back to being fixedly connected with; The middle part of described hub is evenly distributed with three fan-shaped waist holes around the center of circle; The center of circle of described hub is pulled outwardly stretches out a groove; Described bearing is placed on two in the groove of hub, is fixed with seal ring on outside race, and the dual-side of bearing and hub contact site are fixed with dust ring.
Further, on described hub, the binding site between two fan-shaped waist holes is pulled outwardly and stretches out reinforced rib.
Further, between described two hubs, be fixedly connected with nut by screw.
Further, described seal ring is three layers of lip.
Adopt after the technical solution of the utility model, hub adopts integrated stretching design, bearing is placed on two in the groove of hub, integrated design make the dynamic balance of wheel hub, axially and radial runout more tend towards stability, between bearing and hub, be provided with seal ring and dust ring, increase the closed type energy of the gauge wheel of knowing clearly, good leak tightness extends the service life of product.Three fan-shaped waist holes that hub is provided with, in the time of planting with sowing machine, earth can depart from away from three fan-shaped waist holes, and earth is more easily departed from away from wheel hub, has reduced the number of times of cleaning hub, has reduced the load of driving engine simultaneously.
Accompanying drawing explanation
Fig. 1 is sower gauge wheel decomposing schematic representation;
Fig. 2 is the front view after the assembling together of sower gauge wheel;
Fig. 3 is the cutaway view of three layers of lip seal ring.
Wherein: 1, hub, 2, rubber tire, 3, dust ring, 4, bearing, 5, tightening seal washer, 6, nut, 7, screw, 111, fan-shaped waist hole, 112, groove, 113, reinforced rib.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred scheme of the utility model is further elaborated.
As Fig. 1, shown in Fig. 2, a kind of sower gauge wheel, comprises wheel hub, rubber tire 2 and bearing 4, and described rubber tire 2 is fixed on the outer ring of wheel hub, and bearing 4 is fixed on the circle centre position of wheel hub; Described wheel hub by two hubs 1 back to being fixedly connected with; Between described two hubs 1, be fixedly connected with nut 6 by screw 7.The middle part of described hub 1 is evenly distributed with three fan-shaped waist holes 111 around the center of circle; Binding site on described hub 1 between two fan-shaped waist holes 111 is pulled outwardly and stretches out reinforced rib 113.The center of circle of described hub 1 is pulled outwardly stretches out a groove 112; Described bearing 4 is placed on two in the groove 112 of hub 1, and bearing is fixed with seal ring 5 on 4 outer rings, and as shown in Figure 3, seal ring 5 is three layers of lip.The dual-side of bearing 4 and hub 1 contact site are fixed with dust ring 3.
After adopting this preferred mode, hub 1 adopts monoblock high strength stretching steel plate, coordinate the disposable drawing and forming of mould by stretcher, it by steel ring of the prior art, spoke and bearing seat make be one overall, thereby the overbalance and the axial-radial that greatly reduce wheel hub are beated.Before wheel hub changes, full-closed structure, for hollow out designs, stamps out three fan-shaped waist holes 111, and goes out reinforced rib 113 in the downward pressure stretch of part of fan-shaped waist hole 111 combinations, increases mechanical strength and the rigidity of whole wheel hub.While having avoided using, wheel hub is clashed into by hard thing the risk of damaging.When there being earth to enter into wheel hub the inside, along with the rotation of wheel, earth can fall down from three of a wheel hub fan-shaped waist hole 111, plays the effect of automatic removal earth.The seal ring 5 that is fixed with three layers of lip on the outer ring of bearing 4, sealing effectiveness is better, prevents that the junction between the fan-shaped waist hole 111 of earth from two hubs 1 from entering in the groove 112 after two hubs 1 are connected, and causes bearing 4 to rotate inflexible risk.The position that bearing 4 dual-sides contact with hub 1 is fixed with dust ring 3, and actv. has blocked earth and water enters into the risk in bearing 4 from the side of bearing, plays the object of water proof and dust proof, and protection bearing 4 is without prejudice.
