Description

Technical Field

[0001] This utility model belongs to the field of asphalt recycling technology, and in particular relates to an asphalt pavement recycling and regeneration device. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, which is liquid with a black surface and is soluble in carbon disulfide. It is commonly used in road paving projects.

[0003] When the asphalt pavement is aged and damaged, it needs to be recycled using an asphalt pavement recycling device. Then, it is processed and mixed with new asphalt to achieve the purpose of recycling. Existing asphalt pavement recycling devices usually crush and collect the asphalt, and then transport it back to the factory for screening and processing. This not only increases the construction steps and difficulty, but also increases the labor intensity of the workers and affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an asphalt pavement recycling device. Specifically, by setting up a screen plate, the device works by starting motor two, which drives gear four to rotate. Gear four, through an internal gear belt three, drives two gears three to rotate. Limiting rod two contacts the outer surface of the internal gear belt three, ensuring close contact between gear four and the internal gear belt three. Gear three drives the spiral blades to rotate inside the conveying pipe, thus sending the crushed material out of the outlet along the conveying pipe. At this point, the crushed material enters the housing. The vibration motor is then started, and due to the elasticity of the springs, the screen plate vibrates repeatedly, screening the crushed material. This also prevents the crushed material from clogging the screen holes, solving the problem that existing asphalt pavement recycling devices typically lack screening capabilities, thus affecting work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an asphalt pavement recycling device, comprising a housing and a screen plate. Two conveying pipes are fixedly connected to the left side of the housing. Spiral blades are rotatably connected inside the conveying pipes. Gear three is fixedly connected to the bottom of each spiral blade. A gear four is positioned at the center of each of the two gear threes. An internal toothed belt three is provided on the outer surface of each of the two gear threes and gear four, and the two gear threes and gear four are meshed together via the internal toothed belt three. A support frame is fixedly connected to the left side of the housing. A limit rod two is fixedly connected to the bottom of the support frame, and the outer surface of the limit rod two contacts the outer surface of the internal toothed belt three. A motor two is fixedly connected to the top of the support frame. The bottom output end of the second machine is fixedly connected to the top of the fourth gear. The top of the conveying pipe is fixedly connected to the discharge port, and the bottom of the discharge port contacts the top of the screen plate. A support rod is fixedly connected inside the box. The right side of the screen plate is rotatably connected to the outer surface of the support rod. Two support blocks are fixedly connected to the left side of the inner wall of the box. A spring is fixedly connected to the top of the support block. The top of the spring is fixedly connected to the bottom of the screen plate. A vibration motor is fixedly connected to the left side of the bottom of the screen plate. After the vibration motor is started, the screen plate vibrates repeatedly due to the elasticity of the spring, screening the broken material. In this way, it can be screened when recycling asphalt, reducing construction steps and improving work efficiency.

[0007] Furthermore, a feed inlet is fixedly connected to the bottom of the box near the conveying pipe, and several guide plates are fixedly connected to the top of the feed inlet. The guide plates can guide the waste asphalt fragments entering the feed inlet, so that they can enter the conveying pipe more smoothly, improve the processing efficiency of the fragments, and reduce blockage and jamming.

[0008] Furthermore, a first door is provided on the right side of the box near the upper part of the screen plate, and a second door is provided on the back of the box near the lower part of the screen plate. Both the front and back of the box are fixedly connected to baffles. The two doors facilitate the processing of different recycled materials, and the baffles prevent the recycled asphalt from splashing onto the gears, thereby preventing damage to the equipment and improving the stability of the device.

[0009] Furthermore, three crushing rollers are rotatably connected to one side of the baffle, and a gear is fixedly connected to the front of the crushing roller. An internal toothed belt is provided on the outer surface of the three gears. The three gears are meshed and connected through the internal toothed belt. The three crushing rollers are meshed and connected through the gears and the internal toothed belt, which can achieve synchronous rotation, so that the asphalt waste is crushed more fully and the crushing efficiency is improved.

[0010] Furthermore, a limiting rod is fixedly connected to the side of the baffle near the center gear one. The outer surface of the limiting rod one contacts the outer surface of the internal gear belt one. The limiting rod one makes the internal gear belt one in close contact with the center gear one, thereby enabling the center gear one to effectively drive the other two gears one to rotate, thus improving the transmission efficiency.

[0011] Furthermore, a second gear is provided above the first gear located at the center. An internal toothed belt is provided on the outer surface of the first gear and the second gear. The first gear and the second gear are connected by meshing through the internal toothed belt. Since the internal toothed belt has high elasticity and wear resistance, it can absorb some vibration and impact while transmitting power, thereby improving the stability and reliability of the equipment.

[0012] Furthermore, a motor is fixedly connected inside the housing, and a protective shell is provided on the outer surface of the motor. The front output end of the motor is fixedly connected to the back of the gear. The motor transmits power to the crushing roller through the meshing connection of the gear, ensuring the stability and efficiency of power transmission. The protective shell on the outer surface of the motor prevents the crushed material from impacting and damaging the motor, thus improving the stability of the device.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a sieve plate, specifically, starts motor two, which drives gear four to rotate. Gear four drives two gears three to rotate through internal gear belt three. Limiting rod two contacts the outer surface of internal gear belt three, making gear four and internal gear belt three in close contact. Gear three drives the spiral blade to rotate inside the conveying pipe, thereby sending the crushed material out of the outlet along the conveying pipe. At this time, the crushed material enters the box. The vibration motor is started, and due to the elasticity of the spring, the sieve plate vibrates repeatedly to screen the crushed material. At the same time, it can also prevent the crushed material from clogging the sieve holes. In this way, it can be screened when recycling asphalt, reducing construction steps and improving work efficiency.

[0015] 2. This utility model improves transmission efficiency by setting a limiting rod one and a limiting rod two. Specifically, the limiting rod one makes the internal toothed belt one in close contact with the gear one located at the center, so that the gear one located at the center can effectively drive the other two gears one to rotate. The limiting rod two makes the gear four in close contact with the internal toothed belt three, so that the gear four can effectively drive the gear three to rotate.
