Description

Technical Field

[0001] This invention relates to the field of asphalt mixing, and more specifically to a road asphalt processing system and processing method. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's crust. Asphalt is mainly used in coatings, plastics, rubber, and road paving. When stones are heated and their surfaces dry, adding a large number of dry stones to asphalt can cause clumping. To prevent clumping, heated stones need to be gradually added to the molten asphalt. However, current technology lacks a device that can simultaneously heat asphalt and stones and gradually add stones to the asphalt. Summary of the Invention

[0003] This invention relates to the field of asphalt mixing, and more specifically to a road asphalt processing system and method. Its advantages include the ability to simultaneously heat asphalt and stones and gradually add stones to the asphalt, thereby further improving the asphalt processing efficiency.

Two ratchet plates are fixedly connected to the bearing, each ratchet plate having ratchet teeth. A right handle is rotatably connected between the two ratchet plates. A button is slidably connected inside the handle. A spring is installed between the handle and the button, the spring causing the button to slide outward along the handle. Pads are installed on both sides of the button, both pads passing through the handle. The pads can be engaged with the ratchet teeth for fixing. A connecting frame is fixedly connected to the lower end of the handle, and a discharge gate is fixedly connected to the lower end of the connecting frame. A feed inlet is provided on the mixing tank.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] The following is in conjunction with the appendix Figure 1-5Detailed description: A road asphalt processing system and method. The processing system includes a mixing tank 101, a bearing 102, ratchet plates 103, ratchet teeth 104, a handle 105, a button 106, a spring 107, a pawl 108, a connecting frame 109, a discharge gate 110, and a feed inlet 111. The bearing 102 is fixedly connected to the mixing tank 101 by welding. Two ratchet plates 103 are fixedly connected to the bearing 102 by welding. Racket teeth 104 are provided on each ratchet plate 103. The handle 105 is rotatably connected between the two ratchet plates 103 through a shaft hole I. The button 106 slides. Connected inside the handle 105, the spring 107 is installed between the button 106 and the handle 105. The spring 107 is used to make the button 106 tend to slide outward along the handle 105. Pads 108 are installed on both sides of the button 106. Both pads 108 pass through the handle 105 through the opening I. The two pads 108 can be inserted with the ratchet 104 to fix the pads 108. The connecting bracket 109 is fixedly connected to the lower end of the handle 105 by welding. The discharge gate 110 is fixedly connected to the lower end of the connecting bracket 109 by welding. The feed port 111 is provided on the mixing tank 101.

[0025] Furthermore, the mixing tank 101 has a hollow tank-like structure, serving as a mixing space for stones and asphalt. Two ratchet plates 103 are provided with shaft holes I, and the handle 105 is provided with a rotating shaft I. The rotating shaft I is rotatably connected to the shaft holes I, allowing the handle 105 to rotate around the ratchet plates 103.

When the handle 105 is vertically downward, the discharge gate 110 is closed, and the pawls 108 engage with the ratchet plates. In the tooth 104, since the pawl 108 cannot rotate in the opposite direction of the ratchet 104, the discharge door 110 cannot be rotated upward to open, thus locking the discharge door 110. When the button 106 is pressed, the pawl 108 slides out from the ratchet 104, and the handle 105 is rotated upward to open the discharge door 110, thus unlocking the discharge door 110. After unloading, the handle 105 is rotated downward, and since the pawl 108 can rotate in the same direction as the ratchet 104, the discharge door 110 is closed.
