Description

Technical Field

[0002] Asphalt concrete, also known as asphalt concrete, is a mixture made by artificially selecting mineral materials with a certain graded composition (such as crushed stone, crushed gravel, stone chips, sand, mineral powder, etc.) and a certain proportion of road asphalt materials, mixed under strictly controlled conditions.

[0003] Traditional asphalt processing raw material transmission devices can use arc-shaped transmission components to construct the upper end of the conveyor belt into a certain arc shape, thereby preventing the problem of raw material scattering and significantly improving the stability and efficiency of the transmission process. However, long-term use of the raw material transmission device may cause varying degrees of damage to the arc-shaped transmission components, thereby affecting the operation of the raw material transmission device. When these arc-shaped transmission components are damaged, the traditional disassembly and assembly methods are often more troublesome.

Therefore, a raw material transmission device for asphalt concrete processing is proposed to solve the above problems. Utility Model Content

A support assembly is provided at the bottom of the side plate fixing plates 7 on both sides, and a conveyor belt 1 is sleeved on the first transmission shaft 4 at both ends. The conveyor belt 1 is made of rubber material, and the bottoms of the plurality of second transmission shafts 6 are in contact with the inner bottom wall of the conveyor belt 1. A plurality of detachably connected fixing frames 2 are equidistantly distributed on the inclined surface of the upper end surface of the side plate fixing plate 7, and a mounting groove 22 is opened on the upper end surface of the fixing frame 2. The bottom of the arc-shaped transmission assembly is inserted into the interior of the mounting groove 22, and a limiting mechanism is provided inside the fixing frame 2, and the limiting ends at both ends of the limiting mechanism are in contact with the arc-shaped transmission assembly.

[0026] In the utility model, the driving member is started, and the driving member drives the first transmission shaft 4 connected to it to rotate.

The opposite sides of the movable plates 20 on both sides are respectively connected to the limiting blocks 21. The limiting blocks 21 on both sides are inserted into the limiting grooves 16 on the front and rear sides of the mounting block 13.

[0033] It should be noted that when the movable sleeve 18 drives the movable plate 20 to move through the second connecting block 19, the limit block 21 can move along with the movement of the movable plate 20; when the limit blocks 21 on both sides are inserted into the limit grooves 16 at the front and rear ends of the mounting block 13, the arc transmission component can be limited. When the limit blocks 21 on both sides are not located in the limit grooves 16 at the front and rear ends, the arc transmission component can be taken out from the mounting groove 22.

[0040] In an optional embodiment, it further includes a plurality of fixing bolts 15 , which penetrate the outer end surfaces on the front and rear sides of the fixing frame 2 and extend to the interior of the side panel fixing plates 7 on both sides, and the fixing bolts 15 are threadedly connected to the side panel fixing plates 7 .

[0041] It should be noted that when the fixing frame 2 needs to be disassembled and assembled, the fixing frame 2 can be disassembled by rotating the multiple fixing bolts 15, and the replaced fixing frame 2 can be installed on the side panel fixing plates 7 on both sides, and then the multiple fixing bolts 15 can be rotated in the opposite direction to fix the fixing frame 2 on the side panel fixing plates 7 on both sides.
