Automatic sand clearing device

Abstract

The invention discloses an automatic sand clearing device which comprises a clearing box provided with a feeding port and a discharging port, the feeding port is formed in the upper portion, and the discharging port is formed in the lower portion. A filter net is fixed between the feeding port and the discharging port, a supporting strip is arranged below the filter net, and a vibrating motor is arranged below the supporting strip. Motors are arranged on the front face of the clearing box and drive rotating shafts to rotate, and brushing bristles are fixed to the rotating shafts. High-pressure air jets are formed on the two sides of the rotating shafts and communicated with an external air source through an air pipe, and the ligature of the heights of the rotating shafts and the centers of the high-pressure air jets form a straight line. A sand outlet is formed in the lower portion of the clearing box, and a sand-discharging operation opening is formed below the feeding port. The automatic sand clearing device is simple in structure, convenient to use and practical, a casting enters the clearing box and then is vibrated continuously, so that molding sand is vibrated to be loose, the workpiece rolls downwards continuously because the filter net has a gradient, firstly, compressed air is used for clearing away the floating sand of the workpiece through blowing, then the surface is cleared through the brushing bristles, finally, compressed air is used for clearing the workpiece through blowing, and therefore the whole process is continuous and complete.

Description

Technical field [0001] The invention belongs to the field of mechanical devices, and specifically relates to an automatic sand cleaning device. Background technique [0002] Now that the castings in the foundry are completed, the castings need to be cleaned. The commonly used method of sand cleaning is to first hit the castings with an artificial hammer, and then use the vibration of the castings to loosen the molding sand in the castings, and then use compressed air to remove the sand. The molding sand is cleaned to achieve the effect of removing the molding sand. This method has high work intensity, low efficiency, and potential safety hazards. Especially for some spherical and solid cylindrical castings, it is difficult to fix, and at the same time, it is difficult to grasp the strength of manual percussion. The sand effect is not ideal. Summary of the invention [0003] In order to solve the above problems, the present invention discloses an automatic sand cleaning device...

Problems solved by technology

[0002] Now, after the castings in the foundry are completed, the castings need to be sand-cleaned. The commonly used sand cleaning method is to hit the castings with an artificial hammer first, and the molding sand in the castings will be loosened and dropped by the vibration of the castings, and then compressed air will be used to remove the sand. The molding sand is cleaned to achieve the effect of removing the molding sand. This method has high labor intensity and low efficiency, and there are potential safety hazards. Especially for some spherical and solid cylindrical castings, it is difficult to fix them. The effect of sand is not ideal
