Description

Framework oil seal for sprinkling irrigation equipment

Technical Field

The utility model relates to a sealing member field specifically indicates a framework oil blanket for sprinkling irrigation equipment.

Background

The framework oil seal is a typical representative of the oil seal, the oil seal generally serves to isolate parts needing lubrication in a transmission part from the external environment so as not to allow the lubricating oil to leak, the framework serves as a reinforcing steel bar in a concrete member, and the oil seal can keep the shape and the tension.

The sprinkling irrigation equipment is indispensable equipment in agricultural production, landscaping and the like, and more equipment for sprinkling irrigation by using the turbine worm rotary spray gun is used in the sprinkling irrigation process, is often found in the use process of the turbine worm rotary spray gun, the rotating part, namely the gear box, often has internal lubricating oil leakage, external water and dust can easily enter the gear box, the water erodes the bearing to cause the bearing to rust, the dust enters the interior to combine with the lubricating oil to generate a large amount of oil sludge, the bearing is rusted over time, the large amount of oil sludge is clamped between the gears to cause rotation blockage, and the reason for the reason is that the sealing performance of the communication part of the rotating shaft of the rotating part and the outside often cannot meet the performance requirement in order to keep the rotating rotation of the rotating shaft, therefore, a novel skeleton oil seal with certain strength, which can not only guarantee the rotation requirement of the rotating shaft, but also meet the sealing requirement, is needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a skeleton oil blanket for sprinkling irrigation equipment.

The utility model provides a skeleton oil blanket for sprinkling irrigation equipment, includes the rubber body, the internal portion of rubber inlays and is equipped with metal framework, metal framework surface is stained with the binder, metal framework passes through binder and the inseparable combination of rubber body, rubber body axle center cavity, the top of rubber body is the cylinder tube-shape, and the bottom is leaks hopper-shaped, the inside bottom side in top of rubber body cylinder tube-shape is equipped with a plurality of holes of stepping down with metal framework junction, metal framework includes metal barrel and sets up the bottom plate in metal barrel one end, the center of bottom plate is equipped with the through-hole.

Furthermore, the metal framework is made of a carbon steel plate material.

Furthermore, the rubber body is made of nitrile rubber, the nitrile rubber has excellent oil resistance, higher wear resistance, better heat resistance and strong bonding force, and particularly resists lubricating oil, gear oil, motor oil, engine oil, petroleum hydraulic oil and the like containing extreme pressure agent, the nitrile rubber can be used in 120 ℃ air or 150 ℃ oil for a long time, and in addition, the nitrile rubber has good water resistance, air tightness and excellent bonding property.

The utility model discloses the advantage: the utility model not only ensures the rotation of the rotating shaft of the turbine worm rotating spray gun, but also meets the sealing requirement, the internal lubricating oil does not leak, the external water and dust can not enter, the internal environment of the gear box is protected, and the service life of the turbine worm rotating spray gun is greatly prolonged; the utility model relates to a simple structure, preparation convenience possess that the weatherability is strong, stand wear and tear, characteristics that intensity is high have effectively solved the not enough problem of leakproofness that the rotation axis passes through gear box and external connection department.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 2, a framework oil seal for sprinkling irrigation equipment, including the rubber body 1, rubber body 1 is inside to be inlayed and to be equipped with

metal framework

2, 2 surface adhesions of metal framework have binder 3, metal framework 2 closely combines through binder 3 and

rubber body

1, 1 axle center cavity of rubber body, the top of rubber body 1 is the cylinder tube-shape, and the bottom is hourglass hopper-shaped, the inside bottom side in top of rubber body 1 cylinder tube-shape is equipped with a plurality of holes 101 of stepping down with metal framework 2 combination department, metal framework 2 includes metal cylinder 201 and sets up the bottom plate 202 in metal cylinder 201 one end, the center of bottom plate 202 is equipped with through-hole 203.

The metal framework 2 is made of a carbon steel plate material.

The rubber body 1 is made of nitrile rubber.

The utility model discloses when production, utilize the mould to have metal framework 2 of binder 3 through the hole 101 centre gripping surface coating that steps down, recycle the mould and make whole use structure with rubber body 1 and metal framework.

The embodiment of the utility model takes the problem of sealing the rotating shaft 4 and the gear box 5 sprayed by the FSN50 turbine worm rotating spray gun as an example, as shown in figures 4 and 5, the structure of the gear connected with the rotating shaft 4 in the gear box 5 is not shown in the figures,

as shown in figure 4, FSN50 turbine worm rotates the spray gun and spouts the place that the rotation axis 4 stretches out gear box 5 and external intercommunication, in the past, block lubricating oil in the gear box and leak through working of plastics 6 and plastic slab 7, outside water and dust get into, its working of plastics 6 and plastic slab 7 pass through AB glue and connect in the department that needs to seal, however, discover in the use, in order to guarantee that rotation axis 4 has certain rotatability, often leave the clearance between working of plastics 6 and the rotation axis 4, although played certain lubricating oil of preventing and leak, prevent outside water, the function that the dust got into, but still partial lubricating oil leaks, outside water, the dust gets into, and AB glue uses easy ageing for a period of time, the protection greatly reduced to gear box 5 internal environment.

In order to solve the problem, will the utility model discloses use FSN50 turbine worm rotation spray gun to spout, as fig. 5, use the utility model discloses replace working of plastics 6, effectively solve the problem that the leakproofness that original use working of plastics 6 and AB glue brought is not good for FSN50 turbine worm rotation spray gun spouts the life obtains the extension that is showing, has fine society and economic value, is worth promoting.

In addition, this practicality also can be for expanding adaptability, gets rid of the rubber body 1 bottom of leaking hopper-shaped to with the bottom shutoff, similar end cap, as the end cap oil blanket 8 that fig. 6 shows, its application is shown in fig. 5, uses on gear box 5, replaces original plastic slab 7, plays the effect of sealed shutoff.
