a sand making machine

Abstract

The invention discloses a sand making machine. The sand making machine comprises a pedestal and a shell, the shell is provided with a material inlet, a rotor body is arranged in the shell, a plurality of board hammers are uniformly distributed on the rotor body, the shell comprises a first shell and a second shell, the first shell is abutted with the second shell, a lower grate board is fixed to the bottom of each of the first shell and the second shell, the outer sides of the two lower grate boards are respectively fixedly connected with a front grate board and a rear grate board, the front grate board is arranged below the material inlet, a plurality of grate holes are uniformly distributed on the lower grate board and the rear grate board, the pedestal is provided with an automatic shell opening device, and the automatic shell opening device is connected with the first shell or the second shell. The sand making machine has the advantages of simple structure, rapid separation of the first shell and the second shell, convenient inspection, operation convenience, convenient fixed connection or opening of the first shell and the second shell, and making of sandstones with high hardness.

Description

technical field [0001] The invention relates to a sand making device, in particular to a sand making machine. Background technique [0002] Like the gravel used in construction, river sand is an indispensable raw material for concrete in construction projects. From urban buildings to rural houses, water conservancy projects and traffic roads and bridges, as long as it is a concrete structure, river sand is generally required. However, in the process of excavating river sand, the natural environment will be destroyed to a large extent, resulting in the exposed river bottom with many holes, and will cause serious soil erosion, which has a great impact on the environment. Therefore, artificial sand has been paid more and more attention, and its advantages are becoming more and more obvious, but the existing sand making machine, its casing is not easy to open and close, so once a fault occurs, it is very inconvenient to handle, which greatly reduces the work of the sand making m...

However, in the process of mining river sand, the natural environment will be destroyed to a large extent, resulting in the bare bottom of the river full of holes, and it will cause serious soil erosion, which has a great impact on the environment

Therefore, artificial sand has been paid more and more attention, and its advantages are becoming more and more obvious. However, the casing of the existing sand making machine is not easy to open and close, so once a failure occurs, it is very inconvenient to handle, which greatly reduces the work of the sand making machine. efficiency
