Description

Technical Field

[0001] The utility model relates to the technical field of mixing stations, in particular to a hydraulic lifting type mobile mixing station. Background Art

[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 mixers of common mobile batching plants are usually installed on high platforms. Generally, the high platforms are fixed. When the commercial concrete truck receives the materials, a foundation must be built to facilitate the mixer to unload the materials into the tank smoothly. This type of batching plant has certain limitations and is inconvenient to use. In addition, the position of the silo of the mobile batching plant is usually fixed, so when building it, you only need to adjust the angle of the belt conveyor and overlap it between the silo and the mixer. However, the feeding angle of this belt conveyor is fixed. When the height of the silo or mixer changes, or because the material is easy to slip, etc., the inclination angle of the belt conveyor needs to be changed. This type of belt conveyor is not easy to adjust and requires external force intervention, which is extremely time-consuming and labor-intensive. Utility Model Content

[0030] Embodiment 1:

[0031] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a hydraulic lifting mobile mixing station includes a mobile frame 1, a lifting workbench 2, a batching bin 3 and a telescopic feeding belt mechanism 4. The lifting workbench 2, the batching bin 3 and the telescopic feeding belt mechanism 4 are all installed on the mobile frame 1. The telescopic feeding belt mechanism 4 is respectively connected to the feeding end of the lifting workbench 2 and the discharging end of the batching bin 3; the lifting workbench 2 includes a bearing platform 21, a first hydraulic cylinder 22, a telescopic column 23 and a supporting mechanism 24. The bearing platform 21 is installed on the mobile frame through the telescopic column 23 1, at least one first hydraulic cylinder 22 is installed on the mobile frame 1, and the telescopic end of the first hydraulic cylinder 22 is connected to the load-bearing platform 21, and the supporting mechanism 24 is installed on the mobile frame 1; 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 feeding end of the variable angle climbing belt conveyor 6 is hinged to the discharging end of the transverse belt conveyor 5, and the discharging end of the variable angle climbing belt conveyor 6 is hinged to the feeding end of the lifting worktable 2.

[0032] When it is necessary to change the unloading height of the mixer according to the height of the commercial concrete truck, it can be achieved by controlling the height of the load-bearing platform 21 through the first hydraulic cylinder 22. When the height of the mixer changes, the height difference between it and the batching bin 3 will also change. When the height difference changes, the telescopic feeding belt mechanism 4 can change the length and inclination angle, which can adapt to the height change of the mixer on the lifting workbench 2 to meet the normal operation of the mobile mixing station, while avoiding the difficulty of human intervention in adjusting the belt conveyor, thereby improving the practicality of the mobile mixing station.

[0033] Preferably, the support mechanism 24 includes a cross bar 241, a vertical bar 242 and a second hydraulic cylinder 243. The two cross bars 241 are slidably mounted on the mobile frame 1. The vertical bar 242 is vertically arranged and slidably mounted on the cross bar 241. The vertical bar 242 and the cross bar 241 are fixed by a pin shaft. The second hydraulic cylinder 243 is mounted on the mobile frame 1.

[0034] Under the lifting action of the second hydraulic cylinder 243, one end of the mobile frame 1 will be tilted up. At this time, the cross bar 241 can be extended or retracted laterally on the mobile frame 1 to expand or reduce the support distance according to the load-bearing conditions of the foundation to ensure the stability of the mixing station. The vertical rod 242 adjusts the height on the cross bar 241 to adapt to the uneven height of the foundation and prevent the wheel from being damaged due to excessive weight.

[0035] Preferably, two opposite side surfaces of the two cross bars 241 are tooth surfaces, the two tooth surfaces are meshed with gears rotatably mounted on the mobile frame 1 , and the gears are connected to a motor mounted on the mobile frame 1 .

[0036] When the motor is started, the two cross bars 241 can be extended or retracted laterally on the mobile frame 1 through the rack and pinion structure for quick adjustment.

[0037] Preferably, the variable-angle climbing belt conveyor 6 is formed by a plurality of independent conveying belts 8 hinged end to end.

[0038] Convenient for angle changes.

[0039] Preferably, if Figure 3 As shown, a limiting plate 9 is arranged between the independent conveying belts 8 .

[0040] 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.

[0041] Preferably, belt pressure wheels 10 are installed at the hinges of the transverse belt conveyor 5 and the variable angle climbing belt conveyor 6 .

[0042] Used to prevent bending, especially when concave, the belt is prone to bulging and deviation.

[0043] Preferably, extension rollers 11 are provided on both sides of the transverse belt conveyor 5 .

[0044] 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 .

[0045] Preferably, a limit sensor 12 is provided at the outer end of the transverse belt conveyor 5 .

[0046] The limit sensor 12 on the transverse belt conveyor 5 can prevent the equipment from being damaged by collision.

[0047] The working process of the utility model is as follows: when it is necessary to change the unloading height of the mixer on the lifting workbench 2 according to the height of the commercial concrete truck, it can be achieved by controlling the height of the load-bearing platform 21 through the first hydraulic cylinder 22. When the height of the mixer is changed, the height difference between it and the batching bin 3 will also change. When the height difference changes, the telescopic feeding belt mechanism 4 can be used to adapt to the above changes. The transverse belt conveyor 5 moves back and forth on the track 7, pulling the variable angle climbing belt conveyor 6 to change the angle. The redundant variable angle climbing belt conveyor 6 (i.e. the horizontal part) can enter between the tracks 7 with the transverse belt conveyor 5, but does not contact the track 7.

[0048] Note that when the conveyed material changes, such as the particle size or property changes (such as whether it is easy to slip), the telescopic feeding belt mechanism 4 can also be changed to adapt to the above changes.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
