Abstract
The utility model discloses a closing mechanism of a discharging opening of a concrete mixer, which comprises a material door which is positioned on a discharge opening and a mixer shell, wherein, a wedge block which is fastened on the mixer shell is arranged on a wedge joint which is formed by the crossing of the wall of the material door and the mixer shell in the axial direction. In addition, the shape of the wedge block is matched with the wedge joint. Due to the adoption of the structure, the sealing of the wall of the material door and the mixer shell is led to form a face to face sealing, and consequently, sealing conditions are improved. In addition, the problems that a sharp corner of the mixer shell which is arranged at a crossing point of the door wall and the mixer shell is easily ground by materials which are stuck on the wall of the material door to cause leakage. The utility model can be used for closing the discharging opening of the concrete mixer.
Description
Technical field the utility model relates to a kind of closing means, particularly a kind of closing means that is used for the truck mixer discharge port.
The fast development that background technology is built along with highway in China, the demand of Stabilized Soil, cement concrete and the bituminous concrete that road surface pavement is used is increasing, and quality requirement is also more and more higher.On the engineering, these several concrete adopt plant mix equipment production mostly, and agitator is one of critical piece of plant mix equipment.Existing agitator is carrying out material when stirring, and bin gate seals discharge port, and during discharging, bin gate is opened, with the agitator housing of bin gate intersection be a wedge angle, a limit of wedge angle forms the line face with the bin gate wall and seals.In the equipment course of work, often be stained with some materials on the bin gate wall, the agitator housing wedge angle with bin gate wall intersection during swing pair weares and teares easily, causes the gap to be strengthened, material from leakage, even influence mixing effect.
Summary of the invention weares and teares easily for the agitator housing wedge angle that solves the material that is stained with on the bin gate wall pair and bin gate wall intersection, cause the problem of leakage, the utility model provides a kind of closing means of truck mixer discharge port, it comprises, be positioned at the bin gate and the agitator housing at discharge port place, wall and agitator housing at described bin gate intersect the wedging method place that forms, and a shape and the suitable voussoir of wedging method that is anchored on the agitator housing axially is set.Owing to adopted this structure, make the sealing of bin gate wall and agitator housing become the sealing of face face, thereby improved air-proof condition, be not easy to cause wearing and tearing, reduced material from leakage.
As further improvement of the utility model, a voussoir apparatus for adjusting position is set near the agitator housing the described voussoir.After voussoir was worn, by the voussoir apparatus for adjusting position, adjusting wedge made its gap recover desirable amount in the position at bin gate and the crossing wedging method place that forms of agitator housing, uses more convenient, more economical.
Description of drawings specifically describes the specific embodiment of the present utility model below in conjunction with accompanying drawing.Accompanying drawing is a kind of transverse sectional view of the specific embodiment of the closing means of the utility model truck mixer discharge port.
Specific embodiment agitator housing 1 and bin gate 3 are with discharge port 2 sealings, the wall 31 of bin gate 3 and agitator housing 1 intersect the formation wedging method, the suitable with it voussoir of one shape 5 axially is set therebetween, and screw connection 53 is anchored on it on agitator housing 1.A voussoir apparatus for adjusting position 4 is being set on 1 near the voussoir 5 the agitator housing, it comprises and is fixed on the agitator housing 1 gripper shoe 43, bolt 41 and nut 42.After voussoir 5 wearing and tearing, unclamp screw connection 53, regulate bolt 41, voussoir 5 will move in wedging method, and when reaching desirable gap, binding thread jockey 53 can recover sealing effectiveness, economy easy to use.The cross section of voussoir 5 has acute angle shape in bin gate wall 31 and the agitator housing 1 crossing wedging method that forms, acute angle one side 51 is tangent at phase contact 50 places and agitator housing 1, and acute angle another side 52 is tangent with bin gate wall 31.Do like this is for the ease of processing and manufacturing.In order to improve service life the most handy abrasion-resistant stee manufacturing of voussoir.
