Concrete preparation equipment

Abstract

The invention discloses concrete preparation equipment which comprises a sand dumping device for dumping sand quantatively. A pebble dumping device for dumping pebbles quantatively is arranged on theright side of the sand dumping device, a screening device for screening specifications of the pebbles is arranged on the lower side of the pebble dumping device, a conveyor for discharging sand and the pebbles out of an external space is arranged on the lower side of the screening device, and the conveyor is driven by a motor to rotate. The equipment adopting the sand dumping device, the pebble dumping device and the pebble screening device can achieve a large batch sand dumping process on the premise of saving equipment space and can screen the pebbles, so that a condition that actual use ofconcrete which is manufactured by the pebbles which do not meet the specifications is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to concrete preparation equipment. Background technique [0002] The preparation of concrete needs to pre-proportion the sand and gravel, and then mix the sand and gravel into the cement for mixing. When the sand and the gravel are mixed and processed, the sand and the gravel need to be mixed quantitatively, because the general equipment is in the When quantifying and mixing sand and gravel, the hopper is used to preload the material, and then the sand and gravel are drained by using the flap structure, which makes the ratio of sand and gravel unstable to a certain extent, and due to the large After the gravel is used for concrete preparation, it will affect the use of concrete, and personnel are required to sort the process, which increases the labor burden of personnel and reduces the production efficiency of the equipment, and in the process of dumping and mixing larg...
