Detailed Description

As shown in fig. 1-2, an automatic dirt discharging device of a sewage suction truck comprises a mounting bracket 4 fixed in a tank body of the sewage suction truck, a mounting flange 3 is fixed on the mounting bracket 4, a hydraulic motor 1 is fixed at one end of the mounting flange 3, a distributing body 12 is fixed at the other end of the mounting flange 3, two symmetrically arranged water connectors 5 are fixed on the distributing body 12, a rotating shaft 8 concentric with the distributing body 12 is connected in a rotating and sealing manner, the rotating shaft 8 is connected with an output shaft of the hydraulic motor 1 through a coupler 2, the coupler 2 is a torque protection coupler, an inlet hole 16 communicated with the water connector 5 is formed in the distributing body 12, a plurality of through holes 17 are uniformly distributed on the circumference of the rotating shaft 8 corresponding to the inlet hole 16, a central hole 18 is formed in the rotating shaft 8, the central hole 18 is communicated with the through hole 17, a fan blade mounting body 7 is fixed at the right end of the rotating shaft 8, an inverted T-shaped, a plurality of hollow fan blades 6 are uniformly distributed and fixed on the outer edge of the fan blade mounting body 7, the inside of each fan blade 6 is communicated with the inverted T-shaped hole 19, and a plurality of water outlet holes 20 are formed in one side, back to the mounting support 4, of each fan blade 6.

All rotate sealing connection through a sealing member 13 between 8 outer peripheries of pivot and the distributor 12 inner edges of through-hole 17 both sides, distributor 12 both ends are passed through bearing 11 with pivot 8 and are rotated and be connected, bearing 11 is tapered roller bearing, is fixed with bearing cap 10 on the right-hand member of distributor 12, and threaded connection has nut 9 on the pivot 8 on bearing cap 10 right side, and nut 9 tightly supports the bearing 11 inner circle on right side through the axle sleeve, and 8 left sides of pivot and distributor 12 rotate sealing connection through swivel seal 15, and the cover is equipped with retaining ring 14 on the pivot 8 on swivel seal 15 right side, and retaining ring 14 tightly supports left bearing 11 inner circle.

The utility model discloses during the use, pass through the oil pipe intercommunication with hydraulic motor 1 and the hydraulic system of soil pick-up car, make the high-pressure water source intercommunication of water swivel 5 and soil pick-up car, when the water of the internal silt deposit layer top of soil pick-up car jar is more, do not start soil pick-up car high-pressure water source, only start hydraulic motor 1, hydraulic motor 1 passes through shaft coupling 2, pivot 8 and flabellum installation body 7 make flabellum 6 at the internal rotation of soil pick-up car jar, flabellum 6 can make the silt deposit layer carry out the intensive mixing rather than the water of top, thereby conveniently discharge the silt in the soil pick-up car jar body. When the water of silt deposit layer top in the soil pick-up car jar body is less, open soil pick-up car high pressure water source when starting hydraulic motor 1, the water head 5 is passed through to the high pressure water when flabellum 6 pivoted, inlet 16, through-hole 17, centre bore 18 and the hole 19 of falling T shape enter into flabellum 6 inside, then pour into the jar internal of soil pick-up car into after discharging through the apopore on the flabellum 6 for convenient the discharge after silt and the water intensive mixing. The apopore 20 discharge on the water under high pressure through flabellum 6 can make the silt around the flabellum 6 quick mix with water, can reduce the resistance of flabellum 6 fast, and the load that alleviates hydraulic motor 1 that can be quick prevents that hydraulic motor 1 from being damaged because of transshipping for a long time.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
