[0002] Mobile concrete mixing station is a concrete production equipment that integrates the material storage, weighing, conveying, mixing, unloading and automatic control system of a concrete mixing station into a trailer unit. It has all the same action processes, operation methods, and maintenance as fixed automatic mixing stations. It also has unique features such as flexible mobility, quick and easy disassembly and assembly, and simple storage and management. It is the best model for mobile construction of highway, railway, bridge, port, hydropower and other projects.

[0003] The mixer of a mobile batching plant is usually installed on a high platform, and the materials at the lower position need to be transported to the mixer at the higher position through a conveyor belt. The height of the silo and the high platform of a common mobile batching plant are fixed. When building, you only need to adjust the angle of the belt conveyor and overlap it between the two. However, the feeding angle of this belt conveyor is fixed. When the height of the silo or mixer changes, or because the material is prone to slipping, etc., the inclination of the belt conveyor needs to be changed. This belt conveyor is not easy to adjust and requires external force intervention, which is extremely time-consuming and labor-intensive. Utility Model Content

The working platform 2 and the batching bin 3 are both installed on the mobile frame 1. A telescopic feeding belt mechanism 4 is installed on the mobile frame 1, which is connected to the feed end of the working platform 2 and the discharge end of the batching bin 3 respectively. The telescopic feeding belt mechanism 4 includes a transverse belt conveyor 5 and a variable angle climbing belt conveyor 6. The transverse belt conveyor 5 is horizontally arranged and slidably connected to the track 7 of the mobile frame 1. The feed end of the variable angle climbing belt conveyor 6 is hinged to the discharge end of the transverse belt conveyor 5, and the discharge end of the variable angle climbing belt conveyor 6 is hinged to the feed end of the working platform 2.

[0026] The telescopic feeding belt mechanism 4 can change its length and inclination, and can adapt to the height of the mixer on the working platform 2, the position of the batching bin 3 and the changes in the material properties, so as to meet the normal operation of the mobile mixing station, avoid the difficulty of human intervention in adjusting the belt conveyor, and improve the practicality of the mobile mixing station.

[0027] Preferably, the variable-angle climbing belt conveyor 6 is formed by a plurality of independent conveying belts 8 hinged end to end.

[0028] Convenient for angle changes.

[0029] Preferably, if Figure 3 As shown, a limiting plate 9 is arranged between the independent conveying belts 8 .

[0030] The limit plate 9 can play a supporting (load-bearing) role and prevent "collapse" at the hinge when the independent conveyor belt 8 conveys materials.

[0031] Preferably, belt pressure wheels 10 are installed at the hinges of the transverse belt conveyor 5 and the variable-angle climbing belt conveyor 6 .

[0032] Used to prevent bending, especially when concave, the belt is prone to bulging and deviation.

[0033] Preferably, extension rollers 11 are provided on both sides of the transverse belt conveyor 5 .

[0034] The extension roller 11 is used to move the conveyor belt 5 transversely on the track 7 and to prevent the variable angle climbing conveyor belt 6 from interfering with the track 7 .
