An automatic casting sand cleaning machine

Abstract

The invention discloses an automatic casting sand cleaning machine. The automatic casting sand cleaning machine comprises a base; a square tube is arranged on the top of the base and internally provided with a rotary roller; a support is arranged on one side of the square tube and provided with a drive motor connected with the rotary roller; a plurality of rows of brush rods are arranged on the inner wall of the rotary roller at equal intervals; a plurality of brush bristles are spirally arranged on the brush rods; a plurality of through holes different in size are formed in the inner wall of the rotary roller; a mechanical arm assembly is arranged on one side of the square tube and located on the top of the base and comprises a bracket arranged on the base; the upper portion of the bracket is connected with a first mechanical arm arranged perpendicularly; the first mechanical arm is horizontally provided with a second mechanical arm; a clamping jaw is arranged on the second mechanical arm. The mechanical arm assembly is used for taking castings on one side of the sand cleaning machine to the rotary roller, manual operation is omitted, the procedure is rapider and more efficient, and labor funds are also saved. The automatic casting sand cleaning machine has the advantages of being simple in structure, safe to use, automatic in work and the like.

Description

technical field [0001] The invention relates to a cleaning device, in particular to an automatic casting sand cleaning machine. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the resulting object has a certain shape, size and performance. [0003] Molding sand is usually formed on the surface of the newly produced casting, which affects the use of the product. The sand cleaning machine is a device for cleaning the molding sand on the surface of the molded casting. Generally, small-sized castings are manually cleaned on the spot, using iron hooks and hand hammers to operate, which is difficult to control, and the sand-cleaning effect is poor and the efficiency is low; while medium-sized and large-sized castings are mostly...

Problems solved by technology

Generally, small-sized castings are manually cleaned on the spot, using iron hooks and hand hammers to operate, which is difficult to control, and the sand-cleaning effect is poor and the efficiency is low; while medium-sized and large-sized castings are mostly cleaned by sand-cleaning machines, and the existing sand-cleaning The general structure of the machine is complex, the labor intensity is high, and the dust and sand particles generated by it are easy to splash out and cause harm to the workers.
