[0002] As an indispensable equipment in construction engineering, double-horizontal-shaft mixer plays an important role in mixing cement, sand, various dry powder mortar and other building materials. However, the existing double-horizontal-shaft mixer unloading door device has some drawbacks, which seriously affects the working efficiency of the mixer and the quality of the concrete.

[0003] Firstly, the door body of the traditional double-horizontal-shaft mixer unloading door device is prone to deformation after long-term use, which will cause unsmooth unloading and affect the construction progress. Secondly, the existing unloading door device is inconvenient to install and adjust, and the gap is uneven, which not only increases the operation difficulty, but also may cause material leakage and affect the sealing performance of the mixer.

A driving mandrel 21 is welded in the middle of one of the circular flanges 20, and a driven mandrel 22 is welded in the middle of the other circular flange 20. Reinforcing rib plates 23 are also installed between the circular flange 20 and the driving mandrel 21, and between the circular flange 20 and the driven mandrel 22, to enhance the stability of the structure.

[0062] The setting of the door body realizes the following advantages:

[0063] Good integrity: The door body adopts a whole welding structure, and the U-shaped plate and the arc-shaped plate are connected by welding to form a whole, which is compact and not easy to loosen, improving the integrity and stability of the door body, making it not easy to deform or damage during use, and prolonging the service life.

[0064] Stable structure: Reinforcing rib plates are installed between the circular flange and the driving mandrel, and between the circular flange and the driven mandrel. These reinforcing rib plates can effectively disperse and withstand the force acting on the door body, enhancing the stability of the structure, so that the door body can remain stable when subjected to large external forces or vibrations, improving the load-bearing capacity and anti-deformation ability of the door body.

[0067] The driving spindle 21 and the driven spindle 22 are provided with a sealing baffle 17 outside, which prevents the leakage of mud from flowing into the bearing seat 2 and causing damage to the bearing.

[0068] Through the above structure, the novel double-horizontal-shaft mixer unloading device has the characteristics of simple structure, good rigidity, convenient installation and adjustment, tight sealing, reliable support and accurate opening and closing position. At the same time, by optimizing the structure of the door body, the sealing strip and the end seal seat, the possibility of accumulation of dead materials in the triangular low-efficiency area is minimized.

[0069] The working principle of the utility model is as follows:

[0070] Unloading preparation stage: after the mixer completes the mixing of the materials, the unloading operation is prepared. The control system sends a signal, and the telescopic rod of the oil cylinder 6 starts to stretch and retract, driving the swing arm 4 to swing. The swing of the swing arm 4 makes the door body 3 rotate around the bearing seat 2, gradually opening the discharge port.

[0071] Unloading process: after the door body 3 is opened to a certain angle, the materials in the cylinder 1 begin to flow out of the discharge port; the lower inclined surface of the side sealing strip 14 cooperates with the outer cylindrical surface of the door lining plate 12, and the outer edge of the end sealing strip 16 cooperates with the inner cylindrical surface of the end seal seat 15, forming a multi-layer sealing structure, which effectively prevents the leakage of materials during unloading.

[0072] The design of the bent plate 13 helps to guide the materials to flow out smoothly, reduce the accumulation of materials at the discharge door frame, keep the unloading channel unobstructed, and the opening and closing angle of the door body 3 is accurately controlled through the cooperation of the inductive plate 9 and the sensor 11, ensuring the accuracy of the unloading process, avoiding incomplete or excessive unloading, and improving the unloading efficiency.

[0073] Unloading completion stage: when the material unloading is completed, the control system sends a signal, and the telescopic rod of the oil cylinder 6 reversely stretches and retracts, driving the swing arm 4 to swing reversely; the reverse swing of the swing arm 4 makes the door body 3 gradually close until completely closing the discharge port, preparing for the next mixing operation.

[0074] During the whole discharging process, the sealing baffle 17 outside the driving arbor 21 and the driven arbor 22 effectively prevents the leakage of the slurry from flowing into the bearing seat 2, avoids the bearing damage, and ensures the normal operation and service life of the equipment.

[0075] Through the working principle, the novel double-horizontal-shaft mixer discharging device has the characteristics of simple structure, good rigidity, convenient installation and adjustment, tight sealing, reliable support and accurate switch position, and through the optimization design of the door body, the sealing strip and the end sealing seat, the possibility of the accumulation of the dead materials in the triangular low-efficiency area is reduced to the maximum, and the production efficiency of the mixer and the reliability of the material unloading are improved.

[0076] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
