Description

Technical Field

[0001] The utility model relates to the technical field of commercial concrete production and preparation, in particular to a pre-mixing batching and weighing device for commercial concrete production. Background Art

[0002] A pre-mix weighing system for commercial concrete production is a combination of mechanical equipment and sensors. Through precise metering and control, it batches and weighs the raw materials required for concrete production (such as aggregates, powders, and liquids) according to preset proportions, providing accurate raw material ratios for subsequent mixing operations. Pre-mix weighing systems for commercial concrete production are typically installed at the concrete inlet or on the ground. When installed at the inlet, the weighing system is typically tightly integrated with the mixer's feed system. Ground-mounted weighing systems offer greater flexibility and scalability.

[0003] However, the existing technical solutions still have the following problems:

[0004] Once a floor-mounted batching weighing device is fixed, its position is relatively fixed, making it difficult to quickly move or reposition it to accommodate production line changes or site adjustments. Fixed at the feed inlet, a batching weighing device can negatively impact feeding efficiency. Especially during peak production periods, if the device's weighing speed or accuracy doesn't meet requirements, the feeding process can be disrupted, impacting the efficiency of the entire production line. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a pre-mixing batching weighing device for commercial concrete production to at least solve one of the problems raised by the background technology, such as: when multiple projects are carried out in parallel or alternately, the position and configuration of the batching weighing device can be flexibly adjusted to meet the needs of different projects.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pre-mixing ingredient weighing device for commercial concrete production, comprising a weighing trough, a support frame fixedly connected to the outside of the weighing trough, a lifting platform connected below the support frame, and a mobile vehicle fixedly connected below the lifting platform.

[0007] Furthermore: the bottom of the weighing trough is connected with an oblique discharge pipe.

[0008] Furthermore: the inclined discharge pipe and the bottom opening of the weighing trough can be separately arranged.

[0009] Furthermore: the bottom of the support frame and the surface of the lifting platform are fixedly connected by external bolts.

[0010] Furthermore: the bottom of the support frame and the surface of the lifting platform can be set separately.

[0011] Furthermore: a handle is provided on one side of the mobile vehicle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model enables the batching weighing device to be freely moved at the mixing site. It also supports multiple installation methods, including fixing it to the ground, installing it on the commercial concrete feed port, and raising it to align with the feed port. By raising the batching weighing device to align it with the feed port, the distance the raw materials are transported from batching to mixing can be shortened, reducing waiting time and improving production efficiency. In some special environments, the batching weighing device that can be freely moved can better adapt to the environment and ensure smooth production. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] like Figures 1 to 2 As shown, a pre-mixing batching weighing device for commercial concrete production includes a weighing trough 1, a support frame 4 is fixedly connected to the outside of the weighing trough 1, a lifting platform 2 is connected below the support frame 4, and a mobile vehicle 3 is fixedly connected below the lifting platform 2.

[0019] like Figures 1 to 2 As shown, when the present invention is used, a pre-mixing batching weighing device for commercial concrete production uses a support frame 4 to fix and support the weighing trough 1, ensuring its stability and accuracy during the weighing process. The lifting platform 2 is connected to the bottom of the support frame 4. By adjusting the height of the lifting platform 2, the weighing trough 1 can be freely raised and lowered to adapt to feed ports at different heights. The automated lifting function reduces the height and error of manual adjustments, improving the convenience and safety of operation. The mobile vehicle 3 is installed under the lifting platform 2 to provide mobility for the entire device, enabling it to move freely within the mixing station.

[0020] like Figures 1 to 2 As shown, the bottom of the weighing tank 1 is connected to an inclined discharge pipe 5.

[0021] Specifically, the inclined design allows the material to flow out of the weighing trough 1 more smoothly under the action of gravity, reducing the risk of material jamming and blockage. This helps ensure the continuity and stability of material flow and avoids the impact of poor discharge on production progress.

[0022] like Figures 1 to 2 As shown, the oblique discharge pipe 5 and the bottom opening of the weighing trough 1 can be separated.

[0023] Specifically, this arrangement provides a detachable connection between the oblique discharge pipe 5 and the bottom opening of the weighing tank 1, making it easy to remove or install the oblique discharge pipe 5 from the weighing tank 1 when needed. When the device needs to be installed above the feed port, the oblique discharge pipe 5 can be removed in advance to better adapt to the installation space and simplify the installation process.

[0024] like Figure 2 As shown, the bottom of the support frame 4 and the surface of the lifting platform 2 are fixedly connected by external bolts.

[0025] Specifically, this arrangement allows the bottom of the support frame 4 to be tightly fixed to the surface of the lifting platform 2 via external bolts, ensuring a secure and reliable connection between the two. The bolted connection has high strength and rigidity, capable of withstanding the vibration and impact forces generated during the mixing process, ensuring the stability and safety of the device.

[0026] like Figure 2 As shown, the bottom of the support frame 4 and the surface of the lifting platform 2 can be separated.

[0027] Specifically, the design of setting external bolt connection makes it relatively easy to disassemble and assemble the support frame 4 and the lifting platform 2. When it is necessary to move, adjust or maintain the equipment, the operator can use tools to easily unscrew the bolts and separate the support frame 4 from the lifting platform 2.

[0028] like Figure 1 As shown, a handle 6 is provided on one side of the mobile vehicle 3 .

[0029] Specifically, the handle 6 is provided on one side of the mobile vehicle 3 so that the operator can hold the vehicle with one or both hands. The handle 6 is made of a durable material to withstand the tension and pressure during movement. It is easy to hold and not easy to slip off.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
