The invention relates to a grouting machine with a static weighing system and a using method of the grouting machine. The grouting machine comprises a feeding device, a high-speed stirring tank, a material storage tank and the weighing system, wherein the high-speed stirring tank communicates with a material outlet of the feeding device; the material storage tank communicates with a material outlet of the high-speed stirring tank; the weighing system comprises a PLC, a weighing sensor arranged at the bottom of the high-speed stirring tank and a motor controlled by the PLC; and the motor is connected with a high-speed stirring tank stirring device. During operation, the PLC controls the feeding device and the high-speed stirring tank stirring device to work in a coordinating mode; when the weight reaches a certain degree, the high-speed stirring tank stirring device stops working automatically so that the weighing accuracy can be effectively guaranteed; and meanwhile, the PLC can automatically finish whole-course metering control strictly according to the formula of grout, the weighing error of each plate can be controlled within + / -0.5%, and the weighing accuracy is not reduced while continuous operation control is performed.
Description
technical field [0001] The invention relates to a grout press with a static weighing system and a method for using the same. Background technique [0002] In the grouting operation of the prestressed channel, it is necessary to weigh the components of the slurry according to the construction requirements, and the error should be controlled within ±1%. The current weighing method of cutting the material is in the state of high-speed mixing tank stirring There are large errors in cutting and weighing, especially for the slurry controlled by multiple measurement, which will affect the control of the quality of the slurry in severe cases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an accurate weighing grouting machine with a static weighing system and its use method. [0004] The technical solution adopted in the present invention is: a grouting machine with a static weighing system, which is characterized in t...
