Embodiment Construction
[0040] In order to describe the technical content, structural features, achieved purpose and effect of the technical solution in detail, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0041] Please also refer to Figure 1 to Figure 7 , the present invention provides a material crushing mechanism 1 for a sand making machine, the material crushing mechanism 1 includes a grid cage 100, a crushing disc 200 and a rotating main shaft 300;
[0042] The grid cage 100 is used as an accommodating space for the material to be crushed, used for beating, grinding and crushing of the material, and also as a screening mechanism for the material to screen qualified sand bodies of particle size. Specifically, the grid cage 100 includes an upper cage plate 110, a lower cage plate 120 and a grid 130, and the grid 130 includes a plurality of grid bars 131, and the grid bars 131 are formed on the upper cage plate 110 and the lower ca...

The invention relates to the technical field of machine-made sand processing equipment, in particular to a material crushing mechanism for a sand making machine and the sand making machine. The material crushing mechanism comprises a grating cage, a crushing disc and a rotating main shaft, wherein the grating cage comprises an upper cage plate, a lower cage plate and a grating, the grating comprises a plurality of grating bars, the grating bars are uniformly distributed along the circumference at the edge between the upper cage plate and the lower cage plate, a preset gap is formed between every two adjacent grating bars, a feeding hole is formed in the circle center of the upper cage plate, a shaft hole is formed in the circle center of the lower cage plate, the crushing disc is arrangedin the grating cage and comprises a throwing disc and a hammer head, the hammer head is fixed to the throwing disc, the side, facing the grating, of the hammer head extends out of the throwing disc, apreset gap is formed between the hammer head and the grating, and the rotating main shaft penetrates through the shaft hole in the circle center of the lower cage plate and is fixedly connected withthe circle center of the throwing disc. According to the scheme, crushing can be reduced as much as possible under the condition that material particles meet the requirement, the stone powder contentin machine-made sand is reduced, and the finished product yield is increased.
Description
technical field [0001] The invention relates to the technical field of machine-made sand processing equipment, in particular to a material crushing mechanism for a sand making machine and a sand making machine. Background technique [0002] In the field of building materials, concrete is one of the materials used on a large scale. Sand and gravel, as the aggregate of concrete, play the role of skeleton in concrete. Aggregate is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to aggregate with a particle size greater than 5mm, mainly natural rock or pebble; fine aggregate refers to aggregate with a particle size below 4.75mm, mainly river sand. and machine-made sand. Generally, river sand or machine-made sand is divided into fine sand, medium sand and coarse sand according to different particle sizes. Different particle sizes of sand can meet the needs of different products. For example, dry-mixed mortar is mainly composed of fine sand and medium s...
