Description
Technical field
This utility model belongs to rice transplanter field of sealing technology, relates to a kind of rice transplanter oil tank sealing device.
Background technology
Being provided with sealing ring in rice transplanter fuel tank, traditional sealing ring is generally single elastomeric material or other high scores
Sub-material, the sealing ring of this structure is when housing matches, and its sealing effectiveness is difficult to ensure, its material is also easily because of aging change
Shape follows the string, thus service life is shorter, needs frequently to change, affects the operational efficiency of equipment.Owing to sealing effectiveness is paid no attention to
Think, easily make the machine oil in fuel tank or oil leak, cause unnecessary oil consumption to waste, add to user economical negative
Load.
Utility model content
The purpose of this utility model is to provide a kind of rice transplanter oil tank sealing device, strengthens sealing effectiveness, prevents leakage,
Reduce waste, need not frequently change, cost-effective.
For reaching above-mentioned purpose, basic technology scheme of the present utility model is to provide a kind of rice transplanter oil tank sealing device,
Including cabinet, sealing lid, enclosure top has hydraulic fluid port, seals lid and is threaded connection with hydraulic fluid port, seals lid diameter more than hydraulic fluid port
Diameter；Seal cover be provided with embed hydraulic fluid port sealing convex, seal convex in be provided with the pressure sealant made by elastomeric material, pressure
The input of sealant is provided with screw press, and the outfan of pressure sealant contacts with hydraulic fluid port.
When using such scheme, enclosure top has hydraulic fluid port, and hydraulic fluid port adds or takes out the passage of oil plant, is arranged by hydraulic fluid port
Be conducive to the sealing of oil plant in enclosure top, make the oil plant in cabinet be difficult to overflow；Seal lid to be threaded connection with hydraulic fluid port, close
Capping diameter is more than hydraulic fluid port diameter, and rotatory sealing lid is so that seal lid bottom surface beyond the part of hydraulic fluid port diameter and table on hydraulic fluid port
Face completely attaches to, and is isolated with fuel tank in the external world, and the ground floor defining this device seals.Seal to cover to be provided with and embed the close of hydraulic fluid port
Seal convex, seal convex in be provided with the pressure sealant made by elastomeric material, pressure can be done by the elastomeric material of pressure sealant
Going out sensing, when receiving pressure, elastomeric material is extruded and deformation.The input of pressure sealant is provided with screw press, pressure
The outfan of sealant contacts with hydraulic fluid port, rotating screw depression bar so that screw press is descending to the elasticity in pressure sealant
Material extrudes so that its phase output terminal expands, and then fills up space that may be present between outfan and hydraulic fluid port originally, enters
And hydraulic fluid port is implemented closure, the second layer defining this device seals, and the deformation of elastomeric material has diversity so that
The plugging effect in the place sealed is finer and close；And this device need not frequently change encapsulant, when in pressure sealant
Elastomeric material when overrunning and strengthen the descending depth of screw press, and then compensate because the error brought of material consumption.
Such scheme seals at two applied hydraulic fluid port with pressure sealant by sealing to cover, and strengthens sealing effectiveness, prevents
Leakage, reduces waste, and need not frequently change cost-effective.
The preferred version 1 obtaining the improvement of base case, pressure sealant is made up of polyurethane, and polyurethane has well
Wear-resisting and dilatancy, more can meet demand.
The preferred version 2 obtaining the improvement of base case, seals the convex length thickness more than described hydraulic fluid port so that seal
Convex meeting rises up in cabinet, seals convex meeting and is filled up completely with hydraulic fluid port so that sealing effectiveness is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model rice transplanter oil tank sealing device embodiment.
Detailed description of the invention
Below by detailed description of the invention and reference, this utility model is described in further detail:
Reference in Figure of description includes: fuel tank 1, pressure sealant 2, screw press 3, seal lid 4, screw thread 5,
Seal convex 6, hydraulic fluid port 7.
Embodiment is the most as shown in Figure 1: enclosure top has hydraulic fluid port 7, seals lid 4 and passes through screw thread 5 with hydraulic fluid port 7 and be connected,
Seal lid 4 diameters more than hydraulic fluid port 7 diameter；Seal lid 4 and be provided with the sealing convex 6 embedding hydraulic fluid port 7, seal convex 6 length more than hydraulic fluid port 7
Thickness, seal and in convex 6, be provided with the pressure sealant 2 made by polyurethane, the input of pressure sealant 2 is provided with screw press
3, the outfan of pressure sealant 2 contacts with hydraulic fluid port 7.
Enclosure top has hydraulic fluid port 7, and hydraulic fluid port 7 is the passage adding or taking out oil plant, and hydraulic fluid port 7 is arranged at enclosure top
Be conducive to the sealing of oil plant, make the oil plant in cabinet be difficult to overflow.Seal lid 4 to be connected by screw thread 5 with hydraulic fluid port 7, seal lid 4 straight
Footpath is more than hydraulic fluid port 7 diameter, and rotatory sealing lid 4 is so that seal lid 4 bottom surfaces beyond the part of hydraulic fluid port 7 diameter and table on hydraulic fluid port 7
Face completely attaches to, and is isolated with fuel tank 1 in the external world, and the ground floor defining this device seals.Seal lid 4 and be provided with embedding hydraulic fluid port 7
Sealing convex 6, seal convex 6 length more than the thickness of hydraulic fluid port 7 so that sealing convex 6 and can rise up in cabinet, sealing convex 6 can fill out completely
Oil-filled mouth 7 so that sealing effectiveness is better.Sealing and be provided with the pressure sealant 2 that polyurethane makes in convex 6, polyurethane has
Good wear-resisting and dilatancy, more can meet demand；Pressure can be made sensing by the polyurethane of pressure sealant 2, when being subject to
During pressure, polyurethane is extruded and deformation.The input of pressure sealant 2 is provided with screw press 3, the output of pressure sealant 2
End contacts with hydraulic fluid port 7, rotating screw depression bar 3 so that screw press 3 is descending to be squeezed the polyurethane in pressure sealant 2
Pressure so that its phase output terminal expands, and then fill up space that may be present between outfan and hydraulic fluid port 7 originally, and then to hydraulic fluid port 7
Implementing closure, the second layer defining this device seals, and the deformation of polyurethane has diversity so that the ground sealed
The plugging effect of side is finer and close；And this device need not frequently change encapsulant, when the polyurethane in pressure sealant 2 disappears
When consuming excessive and strengthen the descending depth of screw press 3, and then compensate because the error brought of material consumption.
This device by seal lid 4 and pressure sealant 2 hydraulic fluid port is applied two at seal, enhancing sealing effectiveness, prevent
Leakage, reduces waste, and need not frequently change cost-effective.
