Sand mixer facilitating inner wall clearing

Abstract

The invention discloses a sand mixer facilitating inner wall clearing. The sand mixer comprises a sand mixer shell and a sand mixer cover body; a first rotating motor is arranged at the bottom of thesand mixer cover body; a rotating disk is installed at the output end of the first rotating motor; a rotating supporting rod is arranged on the edge of the rotating disk, and is provided with a main impacting block; a second rotating motor is arranged on the rotating disk, and is connected with a rotating wheel which is provided with an eccentric shaft; a connection rod is rotationally connected to the eccentric shaft; the other end of the connection rod is rotationally connected with the main impacting block; an impacting rod is spherically hinged to the rotating supporting rod; a impacting hammer is connected with the bottom end of the impacting rod; and an impacted block is arranged at the top end of the impacting rod. By means of the sand mixer facilitating inner wall clearing, impacting can be continuously performed on the sand mixer shell, it is prevented that molding sand adheres to the inner wall of the sand mixer shell, it is avoided that sand mixing is not uniform, and it isalso avoided that the molding sand cannot be completely discharged during sand outflow, waste of molding sand resources is caused.

Description

technical field [0001] The invention relates to a sand mixer, in particular to a sand mixer which is convenient for inner wall cleaning. Background technique [0002] As a device for mixing molding sand, sand mixer is widely used in foundry industry. In the process of sand mixing, traditional roller sand mixer needs to use binder, so the molding sand mixed with binder is often It will stick to the inner wall of the sand mixer shell, resulting in uneven mixing of the molding sand, which cannot ensure that the sand mixing reaches the required standard, and when the sand is produced, because some molding sand adheres to the inner wall of the sand mixer shell If it is not cleaned up in time, it will stick to the shell of the sand mixer for a long time, and the sand will harden, and it will become very troublesome to remove it from the shell of the sand mixer. The waste of molding sand resources, under normal circumstances, the operator will shake off the molding sand adhered to...

[0002] As a device for mixing molding sand, sand mixer is widely used in foundry industry. In the process of sand mixing, traditional roller sand mixer needs to use binder, so the molding sand mixed with binder is often It will stick to the inner wall of the sand mixer shell, resulting in uneven mixing of the molding sand, which cannot ensure that the sand mixing reaches the required standard, and when the sand is produced, because some molding sand adheres to the inner wall of the sand mixer shell If it is not cleaned up in time, it will stick to the shell of the sand mixer for a long time, and the sand will harden, and it will become very troublesome to remove it from the shell of the sand mixer. The waste of molding sand resources, under normal circumstances, the operator will shake off the molding sand adhered to the sand mixer shell by beating the sand mixer shell, or prevent the molding sand from sticking to the inner wall of the sand mixer shell, but the operation Personnel cannot accurately control the beating time and strength, which can easily cause damage to the sand mixer and affect the service life of the sand mixer
