Description

An integrated vertical concrete mixer

Technical Field

The invention relates to the technical field of concrete mixing, in particular to an integrated vertical concrete mixer.

Background technique

A concrete mixer is a mechanical device used to mix raw materials such as cement, sand, gravel and water to prepare concrete. It is widely used in construction, road construction, bridge engineering and infrastructure construction. By using a concrete mixer, the required concrete can be obtained quickly, which is convenient for building construction. However, most of the current concrete mixers are large in size and usually fixed, and cannot be moved. They are not convenient for loading when in use, lack a loading mechanism, and the loading depends entirely on manual weighing, which is prone to weighing errors.

The conventional measurement method for concrete slump specified in the "GBT20880-2016 Standard for Test Methods of Ordinary Concrete Mixture Performance" is: use a trumpet-shaped slump cone with an upper diameter of 100mm, a lower diameter of 200mm, and a height of 300mm, and fill it with concrete mixture three times. After each filling, use a tamping rod to tamp 25 times evenly from the outside to the inside along the four sides of the barrel wall. After tamping, smooth the upper mouth. After the slump cone is pulled up, the concrete collapses due to its own gravity. The height difference between the slump cone height and the highest point of the concrete mixture after collapse is called slump. The concrete slump specified in the "GB50164-2011 Standard for Concrete Material Control" is generally in the range of 10mm to 220mm. When it is greater than 220mm, its expansion needs to be tested. In the prior art, engineers use a ruler to visually measure the longest diameter of concrete after collapse and its vertical diameter, thereby calculating the expansion of the concrete mixture; and use a ruler to manually measure the height of the highest point of concrete after collapse, thereby calculating the slump of the concrete mixture. The entire measurement process requires the cooperation of multiple people, the process is cumbersome, wastes a lot of labor costs, and is prone to measurement errors.

During the use of existing concrete mixers, it is usually necessary to move the concrete mixture from the mixer to a slump cone, and then fill the concrete in the slump cone into a mold. The whole process requires transferring the concrete mixture many times, requiring a large working surface, and it is difficult to avoid errors caused by human judgment during the operation, which can easily affect the quality of the concrete. The whole process is cumbersome and inefficient.

In view of the above problems, it is very necessary to invent an integrated vertical concrete mixer which integrates feeding, mixing, slump measurement and mold filling, and has the advantages of convenience, speed, labor saving, accuracy and efficiency.

Summary of the invention

In view of the shortcomings of the prior art, the inventors designed an integrated vertical concrete mixer that integrates loading, mixing, slump measurement, and mold filling to make concrete mixing efficient and accurate, avoiding mix weighing errors and slump measurement errors caused by manual operation, which is beneficial to improving the quality of concrete, saving a lot of labor costs, and effectively improving accuracy and efficiency.

The slump cone lifting and sliding module is used to drive the slump cone to move in the vertical direction; the laser infrared rangefinder can determine the highest point of the slump and read the slump height; the slump cone is a hollow structure with openings at both ends of the top and bottom, the switchable disc with a scale is used to measure the expansion of concrete and control the concrete pouring, and the vibration table is used to reciprocate the slump cone to achieve compaction of the concrete in the slump cone.

The mold-filling mechanism is provided with a cubic test block mold and a vibration table, and the vibration table can vibrate and compact the concrete in the cubic test block mold.

Furthermore, in order to improve the durability of the equipment, an anti-corrosion layer is provided on the surface of the push rod device of the present invention, and the anti-corrosion layer is an epoxy resin layer.

In order to improve the control effect of the push rod device, the switch controller is electrically connected to the control and display panel, and the control and display panel is electrically connected to the weight sensor, the mixing barrel, the slump cone lifting and sliding module, the laser infrared rangefinder and the vibration table.

In order to improve the stability of the mixer and the vibration table inside the mixer, the outer frame is welded to each layer of partitions and the bottom layer of partitions, and the bottom end of the vibration surface of the vibration table is provided with anti-slip textures.

In order to improve the applicability of the mixer, the cubic test block mold can be replaced with molds of other sizes, and the discharge funnel must be replaced to adapt the size.

In order to improve the mobility of the mixer, the present invention is provided with universal wheels. When the mixer switch is turned on, the stop of the universal wheel with brake fixes the device at a predetermined position of the device. When the mixer switch is turned off, the mixer can be moved and deployed to meet the construction requirements of different locations.

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

(1) Most existing concrete mixers are large and usually fixed and cannot be moved. It is inconvenient to load materials during use. Loading materials completely relies on manual weighing, which is prone to weighing errors. The inventors designed an integrated vertical concrete mixer that is movable and can automatically load materials. The ratio is weighed by mechanical readings to avoid weighing errors caused by manual weighing, which is convenient for loading materials and improves the quality of concrete construction.

(2) The laser infrared rangefinder of the present invention can determine the highest point of slump and read the slump height, avoiding the error caused by the traditional manual judgment of the highest point of slump, effectively improving the measurement accuracy and efficiency, and the operation process is simple and convenient, without the need for cooperation of multiple people, saving labor costs.

(3) During the use of existing concrete mixers, the concrete mixture must be transferred many times, which makes it difficult to avoid errors caused by human judgment, which easily affects the quality of concrete. In addition, the entire process is cumbersome, wastes a lot of manpower costs, and is inefficient. The inventors designed an integrated vertical concrete mixer that integrates feeding, mixing, slump measurement, and mold filling to make concrete mixing efficient and accurate, avoid errors caused by manual operation, save a lot of labor costs, and effectively improve accuracy and efficiency.
