Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, specifically to a feeding mechanism for asphalt mixture recycling material transportation equipment. Background Technology

[0002] Asphalt mixture is a composite material mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder. Some also contain polymers and wood cellulose. These materials of different qualities and quantities are mixed to form different structures and have different mechanical properties. With the rapid development of science and technology, road paving has become more frequent, resulting in a large demand for asphalt mixtures. Therefore, the recycling of asphalt mixtures is particularly important. However, existing asphalt recycling material transportation equipment often uses conveyor belts or direct manual feeding. Both of these feeding methods are prone to blockages during the feeding process, affecting feeding efficiency. Furthermore, continuous feeding can place an excessive burden on the recycling device, easily causing machine overload or even damage. Therefore, to address the above problems, we propose a feeding mechanism for asphalt mixture recycling material transportation equipment. Utility Model Content

A feeding hopper 3 is located at the center of one side of the top of the screening chamber 1. A screen plate 4 is located inside the screening chamber 1. The screen plate 4 is a downwardly convex arc-shaped plate. An auger 5 is horizontally located inside the screen plate 4. A through groove 6 is opened at the center of the bottom of the screen plate 4 away from the feeding hopper 3. Two relatively rotating crushing rollers 7 are located below the through groove 6.

The screen plate 4 performs a screening function on the material, and the auger 5 on the screen plate 4 rotates, pushing the material to move and screen on the screen plate 4, improving screening efficiency. The auger 5 pushes the large particles screened out on the screen plate 4 to one side of the through groove 6.

The two crushing rollers 7 rotate relative to each other, which can crush the material. The screened material falls into the feed chamber 2, and the drive mechanism runs.

[0018] As a technical optimization of this utility model, guide plates 12 are inclined and symmetrically arranged at the center position above the two crushing rollers 7 and fixed to the bottom of the screen plate 4. The upper distance between the two guide plates 12 is greater than the lower distance, and the through groove 6 is located between the two guide plates 12.

[0019] In this embodiment, large particles screened out on the sieve plate 4 fall down through the channel 6, and the two guide plates 12 act as guides, making it easier for the large particles to fall between the two crushing rollers 7 for crushing.

[0020] As a technical optimization of this utility model, a first motor 13 is provided on the screening chamber 1, and the output shaft of the first motor 13 is coaxially fixedly connected to the auger 5.

[0021] In this embodiment: the first motor 13 is started, so that the auger 5 can rotate, making it easy for the auger 5 to push the material on the screen plate 4 for moving and screening.

[0022] As a technical optimization of this utility model, a second motor 14 and two gears 15 with opposite transmission are respectively provided on the two symmetrical sides of the screening chamber 1. The output shaft of the second motor 14 is coaxially fixed to one end of one of the crushing rollers 7, and the two gears 15 are coaxially fixed to the two crushing rollers 7 respectively.

[0025] In this embodiment: the third motor 19 is started, the main cone wheel 17 and the driven cone wheel 18 are connected to drive the rotating shaft 9 to achieve the function of rotation, so that the large spiral blade 10 on the outer wall of the rotating shaft 9 can easily stir the material, and the small spiral blade 11 can easily convey the material in the screening chamber 1 at a uniform speed, thus achieving the function of uniform feeding. Furthermore, the small spiral blade 11 avoids the material pipe from being blocked.

[0026] As a technical optimization of this utility model, a bearing 20 is provided below the meshing shell 16 and is rotatably connected to the outer wall of the rotating shaft 9. The outer wall of the bearing 20 is provided with a circular array of fixing rods 21 that are fixedly connected to the inner wall of the feed chamber 2.

[0027] In this embodiment, the bearing 20 is fixed to the inner wall of the feed chamber 2 by the fixing rod 21, which further improves the stability of the rotation of the rotating shaft 9.

[0028] Working principle and usage process of this utility model:
