Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a cement mortar aggregate crushing device. Background Art

[0002] Cement mortar is a mortar made from cement, fine aggregate, lime, and water as needed. Aggregate refers to the loose, granular material that serves as a framework or filler in concrete (or cement). Aggregates include pebbles, gravel, and waste slag. Aggregate crushers are now commonly used in the production of cement mortar. Crushers, also known as stone crushers, are pulverizers used in the processing of metal and non-metallic ores.

The crushing device includes a first crushing roller and a second crushing roller that are rotatably arranged in the chassis. The first crushing roller and the second crushing roller are both coaxially provided with a drive motor. A vibrating screen device and a dust collecting device are also provided in the chassis. The vibrating screen device is used to screen the crushed aggregate, and the dust collecting device is used to absorb dust overflowed during the crushing process.

The first inclined plates 10 are arranged so that the aggregate can fall accurately between the two crushing rollers 7.

[0025] The push rod 27 moves through the inner and outer sides of the first crushing box 1. The first crushing box 1 is equipped with a first power mechanism for driving the push rod 27 to move. The first power mechanism includes a sixth servo motor 25 and a threaded rod 26. The outer side of the first crushing box 1 is connected to a bracket 24. The sixth servo motor 25 is installed on the bracket 24. The threaded rod 26 is connected to the output shaft of the sixth servo motor 25. The threaded rod 26 is threadedly connected to the push rod 27.

[0026] The impact plate 12, the rotating plate 13 and the third inclined plate 28 are arranged from top to bottom inside the second crushing box 2.
