Description

Technical Field

[0001] The utility model relates to the technical field of recycled aggregate processing, in particular to a recycled graded milling and stirring device. Background Art

[0002] When processing recycled aggregate (old asphalt pavement), it is usually necessary to use a stirring device to stir the recycled aggregate. However, the size and shape of the recycled aggregate are different. Usually, the discharge port at the bottom of the hopper is blocked due to the excessive size of the recycled aggregate. Although the blockage problem can be solved by adding a vibration motor and a flow aid device to the stirring device, the effect is not very obvious for larger hoppers, and manual dredging is required, which brings inconvenience to the staff.

[0003] Therefore, we proposed a regenerative grading milling and mixing device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a recycled grading milling and stirring device, comprising a hopper, a rotating shaft installed inside the hopper, one end of the rotating shaft extending to the outside of the hopper and equipped with a motor, a plurality of stirring arms for stirring the recycled aggregate installed on the rotating shaft, and a milling head for crushing the recycled aggregate installed at the end of the stirring arm away from the rotating shaft.

[0006] Furthermore: mounting frames are fixed at both ends of the hopper, and the two mounting frames are coaxially arranged, one end of the rotating shaft passes through the hopper and is connected to the bearing installed on the mounting frame, and the other end of the rotating shaft passes through the hopper and is connected to the motor installed on the other mounting frame.

[0007] Furthermore: a sealing sleeve is provided at the connection between the rotating shaft and the hopper, and the sealing sleeve is made of rubber material.

[0008] Furthermore: the end of the stirring arm away from the rotating shaft is arranged in a "bent" shape, and the "bending" direction of the stirring arm is the same as the direction of rotation of the motor.

[0009] Furthermore: a threaded column is fixed to one end of the stirring arm away from the rotating shaft, and a threaded groove used in conjunction with the threaded column is provided on the milling head.

[0010] Furthermore: the overall structure of the hopper is in the shape of an inverted "quadrangular pyramid".

[0011] Beneficial effects of the utility model:

[0012] The utility model has a plurality of stirring arms installed on the rotating shaft. When the motor drives the driving shaft to rotate at a high speed, it can drive the plurality of stirring arms to rotate at a high speed, and the recycled aggregate in the hopper can be stirred by the plurality of stirring arms; a milling head is installed at the end of the stirring arm. The stirring arm can drive the milling head to rotate at a high speed during the high-speed rotation process, and the recycled aggregate in the hopper can be crushed by the milling head, thereby reducing the situation in which the recycled aggregate is too large and causes the hopper to be blocked.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0019] Embodiments of the present utility model:

[0020] A recycled graded milling and mixing device includes a hopper 1. Specifically, the overall structure of the hopper 1 is an inverted "quadrangular pyramid" shape, which can easily put recycled aggregate (recycled aggregate can be old asphalt pavement) into the hopper 1 for subsequent mixing treatment.

[0021] A mounting bracket 6 is fixed at both ends of the hopper 1, and the two mounting brackets 6 are coaxially arranged. The same rotating shaft 2 is rotatably installed between the two mounting brackets 6. It should be noted that: a bearing 7 is provided at the connection between one end of the rotating shaft 2 and one of the mounting brackets 6. Through the setting of the bearing 7, the rotating shaft 2 can rotate more smoothly on the mounting bracket 6. The other end of the bearing 7 passes through the other mounting bracket 6 and is installed with a motor 3. Through the setting of the motor 3, it plays a role in driving the rotating shaft 2, so that the motor 3 can drive the rotating shaft 2 to rotate at high speed; a sealing sleeve 8 is provided at the connection between the rotating shaft 2 and the hopper 1, and the sealing sleeve 8 is made of rubber material. Through the setting of the sealing sleeve 8, it plays a role in sealing the hopper 1 to prevent the recycled aggregate in the hopper 1 from leaking out.

[0022] Multiple rows of stirring components parallel to the axis are installed on the circumferential surface of the rotating shaft 2, and the stirring components of two adjacent rows are staggered, so that the recycled aggregate in the hopper 1 can be stirred more evenly and fewer dead corners occur.

[0023] Specifically, the stirring assembly includes stirring arms 4 equidistantly mounted on the outer surface of the rotating shaft 2 , and a plurality of stirring walls 4 are located on the same straight line; the recycled aggregate in the hopper 1 can be stirred by the plurality of stirring arms 4 .

[0024] More specifically, the end of the stirring arm 4 away from the rotating shaft 2 is set in a "bent" shape, and the bending direction of the stirring arm 4 is the same as the rotation direction of the rotating shaft 2, so that when the rotating shaft 2 drives the multiple stirring arms 4 to rotate, the milling head 4 at one end of the stirring arm 4 can crush the larger recycled aggregate in the hopper 1, reducing the situation where the recycled aggregate particles are too large to block the discharge port of the hopper 1.

[0025] A threaded column 9 is fixed to the end of the stirring arm 4 away from the rotating shaft 2, and a threaded groove 10 is provided on the milling head 5. The milling head 5 can be installed on the threaded column 9 through the threaded groove 10, so that the milling head 5 can be disassembled. If the milling head 5 is damaged after long-term use, it is convenient to repair or replace the milling head 5.

[0026] When processing the recycled aggregate, the recycled aggregate to be processed is first put into the interior of the hopper 1; then the motor 3 is turned on, and the output shaft of the motor 3 can drive the rotating shaft 2 to rotate at high speed, and the rotating shaft 2 can drive a plurality of stirring arms 4 to rotate at high speed, and the recycled aggregate in the hopper 1 can be stirred by the plurality of stirring arms 4; each stirring arm 4 can also drive the milling head 5 to rotate around the axis of the rotating shaft 2 during the rotation process; the larger recycled aggregate in the hopper 1 can be crushed by the milling head 5, so that the size of the recycled material particles in the hopper 1 is relatively uniform, thereby avoiding the phenomenon that the recycled aggregate is too large and causes the hopper 1 to be blocked.
