Dust falling shakeout machine

Abstract

The invention discloses a dust falling shakeout machine. The dust falling shakeout machine comprises a machine body and a gravel circulating assembly installed on the machine body. A coarse sand filter screen is obliquely arranged in the machine body. A coarse sand outlet is formed in the position, at the low-position end of the coarse sand filter screen, of the machine body. The top of the gravelcirculating assembly communicates with a sand inlet in the top of the machine body, and the bottom of the gravel circulating assembly communicates with the coarse sand outlet. The gravel circulatingassembly comprises a vertically-arranged conveying platform and a plurality of circulating material lifting plates. A plurality of bosses are arranged on the conveying platform at equal intervals. Each circulating material lifting plate is hinged to one boss through a torsional spring, and the storage face of each circulating material lifting plate is perpendicular to the surface of the conveyingplatform at the corresponding installation position. Secondary fine crushing can be carried out on gravel which still does not meet the use standard after primary fine crushing, manual screening for re-pouring is not needed, and the time and labor are saved.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a dust reducing and sand dropping machine. Background technique [0002] Shakeout machine is a casting equipment that uses vibration and impact to separate the sand in the mold from the casting. The vibration source of the shakeout machine is divided into three types: mechanical, electromagnetic and pneumatic, and the mechanical inertial shakeout machine is widely used. [0003] In the prior art, the invention patent with the notification number CN106362518A discloses "a falling sand spray dust suppression device and its method". The technical solution includes a sand falling cover, a sand shaking machine, and a sand box. The box is connected with the shakeout machine, and it is characterized in that it also includes a high-pressure fog-making device. The high-pressure fog-making device includes a high-pressure pump, a pipeline, and a high-pressure nozzle, and the high-pressur...

Problems solved by technology

[0005] In the daily production of the foundry, the sand and gravel that fall through vibration are often of different sizes. If they are not crushed and filtered, they cannot be used uniformly. If the first crushing cannot crush all the sand and gravel to a usable level At the same time, the sand and gravel that does not meet the use standards cannot be automatically filtered for the second time, and it needs to be manually sieved to re-pour the finely crushed sand, which is time-consuming and laborious.
