Description

Technical Field

[0001] The invention relates to the technical field of mortar mixing equipment, and in particular to an integrated mortar mixer which is convenient for transportation and assembly. Background Art

[0002] At present, there are three ways to produce mortar required for domestic construction sites; the first is the traditional manual mixer, which is simple to operate. It takes more than three people on site to mix the mortar. The raw material weighing and proportioning control of the mortar is inaccurate, the quality of the mortar is unstable, and the material is wasted. The dust and noise greatly pollute the environment. The second is that the wet mortar is centrally mixed by the mixing station, and the mortar is large in volume; it is not suitable for small mortar. In the hot season, it sets quickly and must be used up within a certain period of time. The mortar variety is single and the production capacity is high. The third is premixed dry mortar, which is produced by a professional manufacturer and requires a factory building. After drying the sand, it is mixed with cement, admixtures and other materials in a certain proportion. Then use the premixed dry mortar truck to deliver it to the construction site. The construction site needs to prepare and store the premixed mortar tank and mixer. When using the mortar, open the mixer under the premixed mortar tank, add water and start secondary mixing, so that the mortar is produced. There are many shortcomings in premixed dry mortar. The sand is wet, and after drying, it produces dust, wastes energy, pollutes the environment, and increases economic costs. On the contrary, it needs to be mixed with water at the construction site, which pollutes the site environment again. The most important thing is that the sand in the premixed dry mortar is dried. After adding water and mixing it twice in a short time, the sand in the mortar is not completely penetrated by water, and it is quickly absorbed during use. The wall needs to be watered for a long time for maintenance, which wastes resources and manpower. Premixed dry mortar often segregates, that is, after segregation, sand, cracks, hollows, etc. will appear when painted on the wall, which is a useless product. The above three mortar production methods cost more than 20%-40% more than the mortar produced by the environmentally friendly mortar integrated production box, which increases the construction cost.

[0003] Previously, someone applied for a patent with publication number 108789852 A. However, in this technical solution, the sand and cement are first weighed above the stirring device and then enter the stirring device. In this process, sand or cement will remain in the weighing device, resulting in errors in the materials when entering the stirring device from the weighing device, causing the stirred mortar to fail to meet the theoretically required quality. Moreover, after a long time, the cement and sand will dry up in the weighing device, resulting in increasing weighing errors and even the weighing device being unusable. In addition, the sand in the above technical solution is transmitted through an auger. The principle of auger transmission is to transport forward by squeezing, so the force between the sand and the auger blades during the transportation process is relatively large, which leads to a large friction between the sand and the auger blades. In addition, due to the relatively large hardness of the sand, the auger blades are particularly severely worn, which in turn leads to a high cost of use, and frequent replacement of the auger blades will affect production; if the material of the auger blades is replaced with manganese steel, not only will the cost be greatly increased, but also because the transmission principle has not changed, friction still exists, and the pressure between the sand and the auger blades is still large, although the service life is longer than before, it still needs to be replaced within a relatively short period of use. Finally, the above technical solution is a completely integrated structure, so a large-sized transport cart is required during the turnover process from the factory to the destination of use to avoid being too long and too wide, which leads to a high transportation cost, and the transportation range of the large-sized transport cart will be greatly restricted, resulting in more troubles in the transportation process. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an integrated mortar mixer that is easy to transport and assemble. By separating the box body A, the box body B and the mixing drum and loading them together for transportation, the present invention can be transported at one time, thereby reducing the transportation cost; by providing a pressure sensor on the supporting legs at the bottom of the mixing drum, the material in the mixing drum can be directly and accurately weighed, thereby ensuring the weighing accuracy of the mixed mortar material and further ensuring the quality of the mortar; through the structure of the mixing blades in the mixing drum, only one driving motor is needed to simultaneously make the material flow direction at the center of the mixing drum opposite to the material flow direction at the edge of the mixing drum during mixing, thereby not only forming a circulation of the material during the mixing process, but also further increasing the contact opportunities between the material at the center and the material at the edge of the mixing drum during the flow of materials in opposite directions, thereby greatly improving the mixing effect; through the structure of the sand conveying device, not only can the sand be effectively conveyed during the closed process, but also the sand dust pollution and material loss caused by the sand can be avoided. Moreover, the conveyor belt is divided into a plurality of conveying grooves, so that the conveying of sand can be preliminarily measured according to the rotation speed; the sidewall structure on both sides of the conveyor belt not only has a low manufacturing cost, but also has a high strength, thereby preventing sand from overflowing from both sides of the conveyor belt and affecting the conveying efficiency of the sand; the structure of the dust cover not only prevents the sand from raising dust when falling into the mixing drum, but also prevents the sand from hitting the dust cover due to inertia when leaving the conveyor belt, causing part of the sand to overflow or hit back onto the conveyor belt, thereby ensuring the conveying efficiency of the sand and avoiding the waste of sand; through the function of the additive batching box, the additive is directly added by weighing the powder or granular material, and the measurement is more accurate compared to the additive solution, thereby ensuring the quality of the mortar; through the function of the cement feeding pipe and the sand conveying device B, it is convenient for cement transport trucks and sand transport trucks to add materials to the cement silo and the sand silo; through the function of the vibrator, even if the sand is wet, it can be prevented from agglomerating and the sand can be broken up under the action of the vibrator, thereby facilitating the conveying of sand.
