The object of the present invention is achieved like this: a kind of blow-down device for engineering machinery oil tank, it comprises flange group, sealing group and magnetic plug group, described flange group comprises fastening flange and blind flange, described fastening flange is fixedly installed on the fuel tank bottom, described blind flange is fixedly installed in the fastening flange bottom, and described blind flange end face is a centroclinal concave surface;
Described sealing group comprises sealing cover and stuffing box gland, described stuffing box gland is fixedly installed on blind flange end face center, described sealing cover is fixedly installed on the stuffing box gland top, described stuffing box gland bottom offers a plurality of grooves, described stuffing box gland center is provided with seal bar, and described seal bar top is set with holddown spring, and the bottom is set with seal ring I, the centre is provided with dividing plate, and the diameter of described dividing plate is identical with the internal diameter of stuffing box gland;
Described magnetic plug group comprises the silk seat, and described silk seat is fixedly installed in the blind flange center, and silk seat bottom is provided with plug I, and described plug I top is provided with magnet steel, and described magnet steel is positioned under the seal bar, and the bottom is provided with plug II.
Described sealing cover center offers oil through.
Described plug I evenly is provided with a plurality of oil through II on the upper-end surface, and described a plurality of oil through II are connected with the cavity that plug II is installed.
Be provided with seal ring II between described plug I and the silk seat, be provided with seal ring III between described plug II and the plug I.
Described groove has 6.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of blow-down device for engineering machinery oil tank of the present invention, when fuel tank works, magnet steel in the magnetic plug group is by the plug I jack-up that makes progress, the seal bar that promotes in the sealing group is upwards lifted, because the fluid settlement action in the fuel tank, particulate pollutant is deposited on the inclination concave surface of blind flange, and under the attraction of centrifugal force and magnet steel, gather magnet steel around, when the needs remove particulate matter, directly plug I is backed out removing and get final product, this moment, seal bar band dynamic seal ring glided simultaneously, and contacted with the inclined-plane of silk seat, under the effect of holddown spring, produce sealed clamping power, preventing that fluid from spilling, thus it can in the situation that not emptying remove the particles settling thing of fuel tank, help regularly to clean fuel tank, when changing fluid, only need be backed out plug II and get final product, and this moment, plug II used as common drain oil, operated also very convenient.

Embodiment
Referring to Fig. 1 ~ Fig. 2, the present invention relates to a kind of blow-down device for engineering machinery oil tank, it comprises flange group 1, sealing group 2 and magnetic plug group 3, described flange group 1 comprises fastening flange 1.1 and blind flange 1.3, described fastening flange 1.1 is fixedly installed on the fuel tank bottom, described blind flange 1.3 is fixedly installed in fastening flange 1.1 bottoms by screw 1.2, and described blind flange 1.2 end faces are a centroclinal concave surface; Described sealing group 2 comprises sealing cover 2.1 and stuffing box gland 2.2, described stuffing box gland 2.2 is fixedly installed on blind flange 1.2 end face centers, described sealing cover 2.1 is fixedly installed on stuffing box gland 2.2 tops, described sealing cover 2.1 centers offer oil through I2.1.1, described stuffing box gland 2.2 bottoms offer 6 bar shaped groove 2.2.1, described stuffing box gland 2.2 centers are provided with seal bar 2.5, described seal bar 2.5 tops are set with holddown spring 2.4, the bottom is set with seal ring I2.3, the centre is provided with dividing plate 2.5.1, and the diameter of described dividing plate 2.5.1 is identical with the internal diameter of stuffing box gland 2.2; Described magnetic plug group 3 comprises silk seat 3.4, described silk seat 3.4 is fixedly installed on blind flange 1.2 centers, silk seat 3.4 bottoms are provided with plug I3.2, described plug I3.2 top is provided with magnet steel 3.1, the bottom is provided with plug II3.6, described magnet steel 3.1 is positioned under the seal bar 2.5, described plug I3.2 evenly is provided with a plurality of oil through II3.2.1 on the upper-end surface, described a plurality of oil through II3.2.1 is connected with the cavity that plug II3.6 is installed, described plug I3.2 root is provided with groove I, be provided with seal ring II3.3 in the described groove I, described plug II3.6 root is provided with groove II, is provided with seal ring III3.5 in the described groove II.
