Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixing equipment, in particular to a color powder additive feeding device for an asphalt mixing cylinder. Background Art

[0002] When the asphalt mixing tank is operating normally, it is necessary to put in bagged and weighed colored powder additives. When the colored powder additives are put in directly through the inspection door on the mixing tank cover, the operators are often inevitably exposed to the harm of high-temperature smoke, which will affect the health of the operators in the long run.

[0003] Therefore, it is urgent to develop a color powder additive feeding device for asphalt mixing cylinder. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a color powder additive feeding device for an asphalt mixing cylinder, thereby preventing operators from being exposed to high-temperature smoke and not affecting the service life of the mixing cylinder.

[0005] The technical scheme adopted by the utility model is as follows: a color powder additive feeding device for an asphalt mixing cylinder, comprising a mixing cylinder, and a feeding hopper is additionally arranged on the feeding side of the mixing cylinder; the structure of the feeding hopper is as follows: it comprises a feeding section and a buffer section arranged in sequence along the feeding direction, the feeding section is a vertically arranged straight tube pipeline structure, and the buffer section is a pipeline structure that is connected to the feeding section and is arranged obliquely; a movable cover plate is installed on the feeding port of the feeding section, the top of the movable cover plate is connected to the cover plate cylinder, and the bottom of the movable cover plate is installed with a cover plate running wheel; a flap is arranged at the junction of the feeding section and the buffer section, and the flap is connected to the flip assembly.

[0006] As a further improvement of the above technical solution:

[0007] Preferably, the structure of the flip assembly is: it includes a rotating part, which is connected to the cylinder output shaft through a connecting rod, and the cylinder output shaft is arranged in the cylinder body; a flap mounting seat is arranged on the other side of the rotating part, and a flap is installed on the flap mounting seat; the cylinder output shaft is telescoped to drive the connecting rod and rotate the rotating part, and the rotation of the rotating part drives the flap to rotate downward for allowing the color powder additive to pass through.

[0008] Preferably, a cylinder fixing seat is installed on the cylinder body, and both ends of the cylinder fixing seat are fixed on the cylinder wall of the buffer section.

[0009] Preferably, an operating table is provided on one side of the feeding port of the feeding section.

[0010] Preferably, the structure of the operating table is as follows: it includes an operator standing area, and a material stacking area is arranged on one side of the operator standing area; the color powder additive is placed in the material stacking area and is fed into the feeding port of the feeding section by the operator.

[0011] Preferably, the mixing tank is a tank structure with an opening at the top.

[0012] Preferably, the top opening of the mixing tank is covered with a mixing tank upper cover.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model has a compact structure and is easy to operate. An operator can stand on an operating table and put the color powder additive material onto the flap through the feeding section of the feeding hopper. As the turning component rotates, the flap rotates downward, and the color powder additive material is evenly put into the mixing cylinder along the slope of the buffer section. The whole process avoids the harm of high-temperature smoke to the operator. At the same time, the design of the buffer section also avoids the material adding speed being too fast to affect the service life of the cylinder body or blades in the mixing cylinder.

[0015] The utility model also has the following advantages:

[0016] The utility model divides the feeding hopper into a feeding section and a buffer section and arranges a flap in the middle to receive the feeding, so that the color powder additive material is fed in two sections from the original higher feeding height, which reduces the impact of feeding on the mixing cylinder and reduces the rise of high-temperature smoke;

[0017] The utility model provides a movable cover plate on the top of the feeding hopper, which is opened when feeding and closed after feeding. After the cover plate is closed, the flap is turned over to further ensure that the operator is not harmed by the overflowing smoke. BRIEF DESCRIPTION OF THE DRAWINGS
