Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, in particular to a process scale metering device. Background Art

[0002] In concrete mix, process scales are used to accurately weigh cement, aggregates and other additives. The reasonable mix of raw materials plays an important role in the strength, durability and other properties of concrete.

[0003] The hook at the lower end of the scale body is convenient for hanging the cement raw material container, which is usually set to a rotating structure. When hanging the cement raw material container, the rotating hook will cause the object to shake and generate a swinging force. The shaking process affects the measurement result of the process scale. It is necessary to wait for the hanging object to be stable before determining the measurement value. For this reason, we propose a process scale metering device to solve the existing problem. Utility Model Content

[0006] When using a process scale metering device in the present scheme, the hydraulic cylinder operates to drive the telescopic rod to lift the lifting plate. The lifting height of the container containing cement raw materials is measured at the upper end of the lifting plate. When it reaches the hook, the hook rotates to hang the container, and the electric hydraulic rod operates. The telescopic end is inserted into the inside of the fixed plate, the lifting plate descends, and the container containing cement raw materials to be weighed pulls the tension spring. The tension spring is pulled up by the force, and the pointer descends to indicate the corresponding position of the scale, so as to understand the weight of the object.

[0007] Preferably, the lower end of the hydraulic cylinder is provided with a telescopic rod, and the upper end of the lifting plate is connected to the telescopic rod. The telescopic rod is driven by the hydraulic cylinder, and when it moves, it drives the lifting plate to move synchronously.

[0008] Preferably, a linear bearing is embedded in the lower end of the scale body, and the lower end of the tension rod is slidably inserted into the linear bearing. The tension rod slides inside the linear bearing, and when the force decreases, the linear bearing aligns the phase to ensure the stability of the tension rod when it moves longitudinally.

[0009] Preferably, a fixed shaft is connected between the mounting blocks, a through hole is provided inside the lower end of the tension rod, and the through hole is rotatably sleeved inside the fixed shaft. The fixed shaft is inside the through hole, and the mounting block is rotatable inside the fixed shaft.

[0010] Preferably, a positioning hole is provided inside the fixing plate, and the lower end of the electric hydraulic rod is inserted into the positioning hole. The electric hydraulic rod is inserted into the positioning hole to fix the fixing plate.

[0011] Preferably, the front end of the scale body is provided with symmetrically distributed scales, and the scales are located on both sides of the visual glass, and the front end of the tension rod is provided with a pointer, and the pointer corresponds to the scale. The scale and the pointer correspond to the weight of the container containing the cement raw material to be weighed, and the pointer position can be observed through the visual glass.

[0013] 1. The utility model provides a fixing plate on one side of the hook, and the lower end of the electric hydraulic rod is inserted into the fixing plate to fix the hook, so that the process scale can achieve stability when measuring the hooked object;

[0014] 2. A lifting device is set under the process scale, and the hydraulic steel drives the lower telescopic rod to drive the lifting plate to lift, which avoids the workers from carrying and lifting the containers containing cement raw materials and saves the workers' physical strength.
