Abstract
The utility model discloses a concrete mixer, which includes a stander, a mixing drum and a mixing main shaft; a sealing part is arranged on the wall where the mixing main shaft passes through the mixing drum; and a bearing supporting component matching with the mixing main shaft is arranged on the stander outside the sealing component of the mixing drum. The bearing is arranged outside the wall of the mixing drum in the utility model, then the sealing part is arranged on the wall where the mixing main shaft passes through the mixing drum, the interior of the original supporting base includes two parts: a shaft end sealing piece and a steady bearing; now the two parts are detached into two independent parts, the sealing structure is redesigned, therefore the bearing cavity is separated from the mixing drum; even if the sealing part wears down, the cement mortar in the mixing drum can not enter the bearing cavity; after improving, the running is more reliable, with little repair and long service life.
Description
Technical field
The utility model relates to a kind of concrete mixer.
Background technology
The axle end bearing of the stirring main shaft of concrete mixer is arranged on the mixing drum sidewall at present, realize keeping apart in bearing chamber and the mixing drum by shaft end seal then, in use shaft end seal weares and teares easily, shaft end seal wearing and tearing back cement mortar just enters the bearing chamber, causes axle end bearing to be worn very soon.
The utility model content
The utility model purpose is to provide a kind of concrete mixer, can improve the axle end bearing application life of the stirring main shaft of mixer greatly.
To achieve these goals, the utility model adopts following technical scheme: a kind of concrete mixer, comprise frame, mixing drum and stirring main shaft, cooperate and be provided with seal member stirring stirring barrel place that main shaft passes mixing drum, on the frame that stirs the barrel seal member outside, be provided with and stir the bearing support that main shaft cooperates.
Described stirring barrel seal member for inboard with stir that main shaft contact surface place is provided with the fluctuate hermetical ring and the outside with stir the skeleton rubber oil sealing that main shaft contact surface place is provided with.
The inboard of described bearing support is provided with the skeleton rubber oil sealing with stirring main shaft contact surface place.
Main shaft between described bearing support and the seal member is provided with rounded tabs.
The utility model is arranged on bearing and stirs the barrel outside, cooperate and be provided with seal member stirring stirring barrel place that main shaft passes mixing drum then, former supporting seat inside has comprised shaft end seal spare and spring bearing two parts, now these two parts are decomposed into two relatively independent parts, the hermetically-sealed construction redesign, thoroughly like this separate in bearing chamber and the mixing drum, even seal member wearing and tearing, cement mortar in the mixing drum can not enter into the bearing chamber yet, because bearing and mixer wall keep at a certain distance away, and the main shaft between bearing support and the seal member is provided with rounded tabs.After having solved spillage, mortar can in time be discharged outside the body, thereby has guaranteed that spring bearing can not contaminated again wearing and tearing.It is more reliable to improve the back operation, and maintenance capacity is few, long service life.

Fig. 2 is a lateral view of the present utility model;
Fig. 3 is a vertical view of the present utility model;
Fig. 4 is the seal member on right side and the structural representation of bearing support.
The specific embodiment
A kind of concrete mixer as Figure 1-3, comprise frame 7, motor 3, hopper 5, rail frame 4, mixing drum 6, stir main shaft 8, motor 3 connects reductor 1 driven gear 2 then, stir main shaft 8 rotations thereby drive, cooperate and be provided with seal member 9 stirring stirring barrel place that main shaft 8 passes mixing drum 6, on the frame 7 that stirs barrel seal member 9 outsides, be provided with and stir the bearing support 10 that main shaft 8 cooperates.
Be illustrated in figure 4 as the seal member 9 on right side and the structural representation of bearing support 10, the left side symmetrical with the structure right side, the main shaft 8 in left side stretches out bearing support 10 and is in transmission connection with gear 2.Stir barrel seal member 9 for inboard with stir that main shaft 8 contact surface places are provided with the fluctuate hermetical ring 11 and the outside with stir the skeleton rubber oil sealing 12 that main shaft 8 contact surface places are provided with, the centre is provided with thrust bearing 16, be provided with O-ring seals between thrust bearing 16 outside parts and the supporting base 18, supporting base 18 is fixed on by big flange 17 and stirs on the barrel.The inboard of bearing support 10 is provided with skeleton rubber oil sealing 12 with stirring main shaft 8 contact surface places, and the main shaft 8 of contact position is provided with cover 15, and the bearing support 14 and main shaft 8 contact positions in skeleton rubber oil sealing 12 outsides are provided with double row cylindrical roller bearing 13.Main shaft 8 between bearing support 10 and the seal member 9 is provided with rounded tabs.
Claims (4)
