Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete mixing technology, and in particular to a mobile vertical shaft mixer concrete mixing plant. Background Technology
[0002] In the field of concrete production, mobile concrete batching plants are widely used in various engineering construction scenarios due to their advantages such as flexible movement and rapid deployment. Existing mobile batching plants use twin-shaft mixers, which have poor mixing uniformity in the same amount of time. Therefore, in order to solve the problem of poor mixing effect, some manufacturers have adopted a mobile vertical shaft mixer.
[0003] However, existing mobile vertical shaft mixers still have certain shortcomings in actual use: on the one hand, concrete raw materials (such as cement) are prone to forming large clumps due to moisture and accumulation, which are difficult to break up effectively by traditional mixing structures, which may lead to poor uniformity of concrete mixing and affect the quality of the project; on the other hand, most existing vertical mixers use dual-shaft rotation mixing, which can only rotate in one direction during the mixing process, which may result in dead zones in the mixing, and the mixing effect may need to be further improved.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1:
[0028] Reference Figures 1-7 A mobile vertical shaft mixer concrete batching plant includes a feed box 2 and a screw conveyor 6 connected to a support 1. An additive addition cylinder 4 is also connected to the support 1. The plant also includes:
[0029] Mixer 3 is fixedly connected to bracket 1;
[0030] Mounting base 8 is rotatably connected to mixer 3. A mixing frame 9 is rotatably connected to mounting base 8. A mixing plate 10 is detachably connected to the bottom of mixing frame 9.
[0031] The first arch-breaking blade 1002 is fixedly connected to the stirring plate 10;
[0032] The second arch-breaking blade 1001 is fixedly connected to the bottom of the stirring plate 10.
[0033] Reference Figure 3 The mixer 3 has a feed inlet 302, and the material conveyed by the screw conveyor 6 will fall into the mixer 3 through the feed inlet 302;
[0034] Reference Figure 3 The bottom of the mixer 3 is also connected to a baffle 301. When the mixing is completed and the material needs to be discharged, the baffle 301 is opened. At this time, the concrete material in the mixer 3 falls into the tanker directly below through the discharge port 101 opened on the support 1.
[0035] It should be noted that the baffle 301 can be opened by a hydraulic rod pulling the crank connecting rod to rotate out, or by other driving methods known in the prior art. This application does not limit or elaborate on the opening method of the baffle 301.
[0036] A drive motor 5 is fixedly connected to the mixer 3. A drive rod 501 is fixedly connected to the drive end of the drive motor 5. A first gear 5011 is fixedly connected to the end of the drive rod 501 away from the drive motor 5. A first gear ring 7 is rotatably connected to the mixer 3. The first gear ring 7 is fixedly connected to the mounting base 8, and the first gear 5011 meshes with the first gear ring 7.
[0037] A rotating rod 901 is rotatably connected to the mounting base 8, and the rotating rod 901 is fixedly connected to the stirring frame 9.
[0038] A second gear 9011 is fixedly connected to the rotating rod 901, and a second gear ring 12 is fixedly connected to the mounting base 8. The second gear 9011 meshes with the second gear ring 12.
[0039] Before mixing, the workers pour the concrete raw materials to be mixed into the feed box 2, and then transport the raw materials to the mixer 3 through the screw conveyor 6. Finally, water and additives are added to the mixer 3.
[0040] When stirring, the drive motor 5 is started, which will drive the drive rod 501 connected to its drive end to rotate. The rotation of the drive rod 501 will drive the first gear 5011 fixedly connected to its bottom to rotate. The rotation of the first gear 5011 will drive the first gear ring 7 meshing with it to rotate. The rotation of the first gear ring 7 will drive the mounting base 8 fixedly connected to it to rotate. When the mounting base 8 rotates, the mounting base 8 will drive the stirring frame 9 and the stirring plate 10 to rotate. At this time, the stirring frame 9 and the stirring plate 10 will stir and mix the raw materials in the mixer 3.
[0041] When the mounting base 8 rotates, the mounting base 8 will synchronously drive the rotating rod 901 to rotate. When the rotating rod 901 rotates, the second gear 9011 on the rotating rod 901 meshes with the second gear ring 12 fixedly connected to the mounting base 8. At this time, the rotating rod 901 will rotate on its own, thereby driving the mixing frame 9 and the mixing plate 10 to rotate on their own. At this time, the rotating mixing frame 9 and the mixing plate 10 can further mix the mixed raw materials in the mixing machine 3, further improving the mixing effect of concrete raw materials.
[0042] After mixing is completed, the workers drive the tanker truck directly below the discharge port 101, open the baffle 301 on the mixer 3, and the concrete mixed in the mixer 3 is transported into the tanker truck through the discharge port 101.
[0043] Two sets of scrapers 11 are fixedly connected to the mounting base 8, and the two sets of scrapers 11 are symmetrically connected to the mounting base 8.
[0044] It should be noted that the scraper 11 is in contact with the inner wall of the mixer 3.
[0045] In practice, the two sets of scrapers 11 connected to the mounting base 8 can effectively scrape off the material on the inner wall of the mixer 3, thereby further ensuring the mixing effect of the concrete.
[0046] Both the first arch-breaking blade 1002 and the second arch-breaking blade 1001 are conical blades.
[0047] With the first arch-breaking blade 1002 and the second arch-breaking blade 1001 set on the mixing plate 10, the two sets of arch-breaking blades can effectively cut up large pieces of hardened cement material during concrete mixing, thereby effectively improving the mixing effect of concrete.
[0048] It should be noted that all components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art. The electrical equipment is connected to an external safe power source. These will not be described in detail here.
[0049] The control circuits for the screw conveyor 6 and the drive motor 5 can be implemented by simple programming by those skilled in the art. They are common knowledge in the field and are only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
