Sand making machine uniform in crushing

Abstract

The invention discloses a sand making machine uniform in crushing. The sand making machine comprises a first crushing mechanism, a second crushing mechanism, a transmission mechanism, a lifting mechanism and a base, wherein the first crushing mechanism comprises a first crushing box, a first motor and a first rotating shaft, and the second crushing mechanism comprises a second crushing box, an outer crushing roller and an inner crushing roller; the transmission mechanism comprises a transmission case, a second motor, a second rotating shaft, a bearing and a belt wheel; the lifting mechanism comprises hydraulic cylinders and telescopic columns, and the number of the hydraulic cylinders and the number of the telescopic columns are both two; the lifting mechanism is arranged below the liftingmechanism. The sand making machine can be used for evenly crushing gravel materials.

Description

technical field [0001] The invention relates to the technical field of sand making, in particular to a sand making machine with uniform crushed materials. Background technique [0002] Sand making equipment is specially used to produce sand for construction and road use; like the third generation sand making machine and the fifth generation sand making machine, etc. are all sand making equipment; in addition, sand making equipment and crushing equipment and screening convey The equipment can form a sand making process such as a sand making production line and a sand and gravel production line; the sand making equipment can make various rocks, sand and river pebbles into construction sand that meets various particle sizes, and the manufactured sand has uniform particle size and pressure resistance High strength, far more suitable for construction requirements than natural sand and sand produced by ordinary hammer sand making machines, and can improve construction quality; this ...

[0002] Sand making equipment is specially used to produce sand for construction and road use; like the third generation sand making machine and the fifth generation sand making machine, etc. are all sand making equipment; in addition, sand making equipment and crushing equipment and screening convey The equipment can form a sand making process such as a sand making production line and a sand and gravel production line; the sand making equipment can make various rocks, sand and river pebbles into construction sand that meets various particle sizes, and the manufactured sand has uniform particle size and pressure resistance High strength, far more suitable for construction requirements than natural sand and sand produced by ordinary hammer sand making machines, and can improve construction quality; this equipment has many characteristics such as reliable performance, reasonable design, convenient operation, and high work efficiency. With the development of my country's construction industry, the crushed material of the sand making machine in the prior art is not uniform enough to meet the needs of the modern construction industry. Therefore, it is particularly important to design a sand making machine with uniform crushed materials.
