Description

Novel asphalt recycling metering scale unloading mechanism Technical Field The utility model belongs to the technical field of asphalt discharging mechanisms, and particularly relates to a novel asphalt recycling metering balance discharging mechanism. Background The asphalt recycling metering scale is key equipment for realizing accurate metering of waste asphalt mixture in an asphalt mixing plant, and the technical performance of a discharging mechanism directly influences recycling proportioning precision and production efficiency. At present, a discharging mechanism commonly adopted in the industry is a double-door independent driving structure. The traditional asphalt reclaimed material metering and weighing discharging door is of a double-door structure, each material door is controlled by one air cylinder, the two material doors are not connected with each other, and because of air pressure fluctuation, response delay and mechanical assembly errors of the double air cylinders, the two discharging doors are difficult to realize complete synchronous action, cannot be synchronously opened or closed, and are easy to cause material door clamping and are complex in operation. Therefore, a novel discharging mechanism of the asphalt recycling metering scale is provided. Disclosure of utility model The utility model aims to provide a novel asphalt recycling metering balance discharging mechanism, and aims to overcome the defects in the prior art, two discharging doors can be linked to realize synchronous opening or closing, so that the material door is prevented from clamping materials, and the novel asphalt recycling metering balance discharging mechanism is simple in structure, simple in operation and control and convenient to install. In order to achieve the aim, the utility model adopts the technical scheme that the novel asphalt recycling metering balance discharging mechanism comprises a door body shell, wherein the door body shell is of a square structure, a left discharging door and a right discharging door are arranged on the door body shell through a discharging door shaft, a left synchronous gear set and a right synchronous gear set are arranged on the discharging door shaft through key connection, a cylinder is arranged on the door body shell through a cylinder mounting seat, and the cylinder is connected with the left discharging door and the right discharging door through a crank arm and a shaft sleeve. Preferably, the door body shell is of a square structure formed by four connecting plates in a connecting mode, and the discharging door is internally installed and installed on the bucket body connecting plates through bolt connection to form a sealing structure. Preferably, the left and right synchronous gear sets are 1/4 gears, and are connected and installed on the discharging door shaft through keys. Preferably, the bottom of the door body shell is provided with a wear-resistant lining plate made of NM400 wear-resistant steel, the thickness of the wear-resistant lining plate is 5-8mm, and the wear-resistant lining plate is connected with the door body shell through countersunk bolts. Preferably, the cylinder adopts a double-acting cylinder, the diameter of the cylinder is 80-100mm, the stroke is 150-200mm, the end part of a piston rod of the cylinder is provided with a universal joint, and the universal joint is provided with a pin shaft. Compared with the prior art, the utility model has the advantages and positive effects that, 1. The utility model realizes accurate synchronization of the two material doors by utilizing gear meshing, and ensures that the two doors are opened or closed simultaneously; 2. according to the utility model, the two discharging doors can be linked to realize synchronous opening or closing, so that the material door is prevented from clamping materials, and the device has the advantages of simple structure, simple operation control and convenient installation.
