Abstract

A concrete mixing carrier, comprising a vehicle chassis and a mixing drum provided thereon. A drum housing of the mixing drum is cubic, supported horizontally on the vehicle chassis, and able to form an unloading state where a front portion is higher and a rear portion is lower; the mixing drum forms a closed drum housing; a feed inlet and a discharge outlet are respectively provided on a rear end plate; a rotary inner drum formed by splicing movable blades is provided in the drum body, and adjacent movable blades have therebetween a movement margin for rotation; each strip-shaped movable blade is supported at both ends by paired rollers respectively; stirring blades overhang towards inside of the drum body, backs of back plates are provided with drive racks, and drive gears, mutually engaged with the drive racks, are provided at corresponding positions of the drum body using a supporting bracket.

First claim

We claim:

1. A concrete mixing carrier, comprising a vehicle chassis and a mixing drum provided on the vehicle chassis, wherein the mixing drum is approximately cubic and horizontally supported on the vehicle chassis, and has a hinged rear support as a fulcrum of rotation; and the vehicle chassis is provided thereon with a lifting mechanism configured for lifting a front end of the mixing drum when unloading, to form an unloading state in which the mixing drum has a front portion higher and a rear portion lower;
the mixing drum comprises a detachable drum body formed of a bottom plate, a left side plate, a right side plate and a top plate, and the drum body is provided with a front end plate at a front end surface and a rear end plate at a rear end surface, to make the drum body form a closed drum housing; and a feed inlet and a discharge outlet are provided on the rear end plate;
a plurality of strip-shaped movable blades are provided inside the drum body along a length direction of the drum body, the movable blades are spliced to form a rotary inner drum disposed in the drum body, and adjacent movable blades are configured to have therebetween a movement margin for rotation; both ends of the movable blades are supported by paired rollers respectively, and the paired rollers are mounted on an inner side wall of the drum body at corresponding positions by using a supporting bracket;
each movable blade comprises a back plate, and a stirring blade which is provided on a front surface of the back plate and at middle of the back plate along a length direction of the back plate and overhangs towards an inside of the drum body, a drive rack is provided on a back surface of the back plate in a width direction of the back plate, and a drive gear mutually engaged with the drive rack is provided at a corresponding position of the drum body by using a supporting bracket; and a drum wall of the rotary inner drum is formed of the back plate.

2. The concrete mixing carrier according to claim 1 , further comprising a front end inclined end plate and a rear end inclined end plate, wherein the front end inclined end plate and the rear end inclined end plate are inclined towards an inside of the drum body, are respectively provided at both ends of the stirring blade on the front surface of the back plate, and are configured such that the rotary inner drum is gradually narrowed at a front end and a rear end.

3. The concrete mixing carrier according to claim 2 , wherein two adjacent movable blades are in hinged connection with each other through the back plate.

4. The concrete mixing carrier according to claim 3 , wherein a water stop belt is provided between two adjacent back plates and between two adjacent inclined end plates.

5. The concrete mixing carrier according to claim 4 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

6. The concrete mixing carrier according to claim 5 , wherein the drive gear is driven by a motor through a drive shaft.

7. The concrete mixing carrier according to claim 3 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

8. The concrete mixing carrier according to claim 7 , wherein the drive gear is driven by a motor through a drive shaft.

9. The concrete mixing carrier according to claim 2 , wherein narrowed openings, formed by the front end inclined end plate and the rear end inclined end plate, and the front end plate and the rear end plate, respectively, form a rotary seal structure.

10. The concrete mixing carrier according to claim 9 , wherein an inclining gradient of the front end inclined end plate on the back plate is greater than an inclining gradient of the rear end inclined end plate on the back plate.

11. The concrete mixing carrier according to claim 7 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

12. The concrete mixing carrier according to claim 6 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

13. The concrete mixing carrier according to claim 2 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

14. The concrete mixing carrier according to claim 13 , wherein the drive gear is driven by a motor through a drive shaft.

15. The concrete mixing carrier according to claim 1 , wherein a support roller, configured for supporting the rotary inner drum, is provided at a bottom of the rotary inner drum, and a supporting bracket of the support roller is welded on the inner side wall of the drum body.

16. The concrete mixing carrier according to claim 5 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

17. The concrete mixing carrier according to claim 16 , wherein the drive gear is driven by a motor through a drive shaft.

18. The concrete mixing carrier according to claim 1 , wherein the stirring blade is inclined towards a direction of rotation of the rotary inner drum.

19. The concrete mixing carrier according to claim 18 , wherein the drive gear is driven by a motor through a drive shaft.

20. The concrete mixing carrier according to claim 1 , wherein protective frames, welded onto the vehicle chassis, are provided on opposite sides of the mixing drum, respectively.
