Description

Technical Field

[0001] This utility model relates to the field of mixing plant technology, specifically to a mobile mixing plant. Background Technology

[0002] Mobile mixing plants are common mechanical equipment in construction engineering, used to efficiently mix various raw materials into the required concrete or mortar. Traditional mixing plants are usually bulky, inconvenient to install and move, and therefore mainly used on fixed construction sites. With the increasing flexibility of construction sites, the development of portable mixing plants has inevitably become a research hotspot. These portable mixing plants, while maintaining efficient mixing functions, also need to be easy to move and have high space utilization to cope with different working conditions and construction needs. Although existing mobile mixing plants have been improved in many aspects, there is still room for improvement in material conveying, weighing accuracy, reliable safety protection, and ease of operation. Improving the stability and accuracy of material conveying, enhancing shock resistance, ensuring the accuracy of weighing data, simplifying operating procedures, and providing user-friendly design are urgent problems to be solved in current mobile mixing plant technology. In addition, the mixers of common mobile mixing plants are generally installed on elevated platforms, which are usually fixed. When concrete trucks pick up materials, a foundation must be built to facilitate the smooth unloading of materials into the truck's container. This type of mixing plant has certain limitations and is inconvenient to use. With the development of construction technology, there are higher demands for the intelligence and safety of concrete mixers. Therefore, developing a mobile mixing plant that is more optimized in design and structure and easier to use is of great significance for promoting efficient operations in the construction industry.

[0003] To address this, a mobile mixing plant is provided, designed to improve conveying efficiency, precisely control material weight, and provide more flexible operating conditions to adapt to different construction needs. Utility Model Content

After being mixed and processed on the working platform 7, the sand and gravel are sent to the pouring device 8 through an inclined funnel and then poured into the cement tanker.

[0025] To better realize this utility model, both the first conveying device 5 and the second conveying device 6 are composed of a driving roller, a driven roller, an inclined support assembly and a conveyor belt (not shown in the figure).
