Mixing, forming and instrument cleaning integrated device for cement mortar test piece

Abstract

The invention relates to a mixing, forming and instrument cleaning integrated device for a cement mortar test piece. The device comprises a rack and a vibration device for mounting a forming mold, wherein a motor is mounted on the rack through a lifting device, the motor is connected with a stirring device through a steering drive mechanism, a plurality of cleaning ports are also formed in the stirring device and connected with a water supply device, and the cleaning ports and the water supply device constitute a cleaning device; the lower end of the stirring device can extend into a mixing pot, and the mixing port is mounted on the rack through a horizontal sliding device; a charging port is formed in the bottom of the mixing pot, and the mixing pot can be moved above the forming mold. The mixing pot can be taken down horizontally, and the condition that cement mortar flows out due to oblique taking out of the mixing pot can be avoided. The device integrates test room cement mortar mixing, test piece forming and instrument cleaning, the test time can be saved, waste of cement mortar mix and evaporation of moisture can be reduced, and the accuracy of test results can be guaranteed.

Description

technical field [0001] The invention belongs to the field of cement mortar mixing equipment, and in particular relates to an integrated device for mixing, forming and instrument cleaning of cement mortar test pieces. Background technique [0002] Cement mortar test is an important basis for cement quality assessment and can assess the strength level of cement. The cement mortar test involves multiple processes such as cement mortar charging, mixing, molding, instrument cleaning and strength testing, among which the cement mortar charging, mixing and molding conditions are the key to the success of the cement strength test, and the cement mortar specimen Important equipment such as cement mortar mixers and vibrating tables will be used for mixing and forming. According to JTG E30-2005 "Cement and Cement Concrete Test Regulations for Highway Engineering", cement mortar specimens need to go through multiple processes during the molding and mixing process. Water is added to the...

Problems solved by technology

[0003] For the above series of operating procedures, there will be the following shortcomings or deficiencies when the cement mortar test is carried out in the laboratory: First, in the cement mortar mixing process, the blades and the pot wall are manually mixed within 90 seconds. It is relatively hasty to scrape the plastic sand into the pot, because the mixing pot needs to be removed from the mixing equipment before scraping, and then the mixing pot needs to be put on the mixing equipment table. These two processes will take up a considerable amount of time. For a long time, it is difficult for those who are not proficient in equipment operation or have poor hands-on ability to complete the operation within the specified time, which will seriously affect the normal progress of the test.

Second, when the mixing pot is removed from the test stand, the mixing pot is in a tilted state. When the mixed cement mortar test piece is relatively thin, it will cause the mortar to flow out

Third, after the cement mortar is mixed, use a spoon to put the mortar into the mold from the mixing pot, which will not only cause the loss and waste of the mortar, but also cause the evaporation of water, especially in summer when the temperature is high. More serious, this will affect the test results of cement mortar strength and shrinkage performance

Fourth, after the filling of the mixing pot is completed, the mixing pot needs to be removed from the mixing equipment table for rinsing and cleaning, which will waste a certain amount of time. Pot cleaning difficulty
