[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, mostly existing in liquid or semi-solid petroleum form. It has 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 is mainly used in industries such as coatings, plastics, and rubber, as well as in road paving.

[0003] During the production of asphalt particles, it is necessary to accurately screen asphalt particles of different sizes, which requires the use of a screening machine. However, in the operation of existing screening machines, asphalt particles are very easy to adhere to and clog the screen mesh, which will affect the normal use of the screening machine and reduce production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning screening machine for asphalt particle production, in order to solve the problem mentioned in the background art that asphalt particles easily adhere to and clog the screen mesh during the use of existing screening machines, thereby affecting the normal use of the screening machine and reducing production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning screening machine for asphalt particle production, comprising:

[0006] The machine body includes the screening machine body, and the screening machine body is provided with a screen inside;

[0007] The cleaning mechanism includes a drive motor, which is fixedly connected to the outer surface of the screening machine body. A rotating roller is fixedly connected to the output end of the drive motor. A lead screw is fixedly connected to the end of the rotating roller away from the drive motor.

[0008] Preferably, the limiting mechanism includes a placement plate, which is fixedly connected to the surface of the screening machine body. An abutment plate is fixedly connected to the upper surface of the placement plate, and a support plate is fixedly connected to the upper surface of the placement plate. A screw is threadedly connected to the surface of the support plate, and a movable plate is fixedly connected to the surface of the screw. A limiting plate is movably connected to the surface of the movable plate.

[0009] Preferably, the drive motors are symmetrically distributed in two groups on the surface of the screening machine body, and the rotating rollers are rotatably connected to the screening machine body through the drive motors.

[0010] Preferably, the lead screw is rotatably connected to the screening machine body via a rotating roller, and the moving plate is slidably connected to the screening machine body via the lead screw.

[0011] Preferably, the sleeves are evenly distributed in five groups on the upper surface of the moving plate, and the slide rod is composed of two cylinders with different radii.

[0012] Preferably, the two ends of the spring are fixedly connected to the movable plate and the scraper, respectively, and the scraper is slidably connected to the screen through the movable plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 One embodiment provided by this utility model:

[0026] A self-cleaning screening machine for asphalt particle production includes:

[0027] The machine body includes the screening machine body 1. The screening machine body 1 is an existing product and is not considered a technical protection point of this application. It will not be described in detail here. The screening machine body 1 is equipped with a screen 11, which is used for screening.

[0028] The cleaning mechanism includes a drive motor 2, which is fixedly connected to the outer surface of the screening machine body 1. The drive motor 2 drives the rotating roller 21 to rotate. Two sets of drive motors 2 operate synchronously. The output end of the drive motor 2 is fixedly connected to the rotating roller 21, which drives the lead screw 22 to rotate. The two sets of rotating rollers 21 rotate synchronously. The end of the rotating roller 21 away from the drive motor 2 is fixedly connected to the lead screw 22. The lead screw 22 drives the moving plate 23 to drive the scraper 27 to reciprocate. The movement of the scraper 27 can scrape off the asphalt particles that are stuck to the screen 11, causing the particles to detach from the screen 11, thereby preventing the asphalt particles from clogging and affecting the normal operation of the screening machine. The threads of the two sets of lead screws 22 are the same. The moving plate 23 is movably connected to the surface of the lead screw 22. The moving plate 23 drives the scraper 27 to reciprocate. The movement of the scraper 27 can scrape off the asphalt particles that are stuck to the screen 11, causing the particles to detach from the screen 11, thereby preventing the asphalt particles from clogging and affecting the normal operation of the screening machine. To prevent asphalt particles from clogging the screening machine and affecting its normal operation, a sleeve 24 is fixedly connected to the upper surface of the moving plate 23. A sliding rod 25 is slidably connected to the surface of the sleeve 24. The sleeve 24 and the sliding rod 25 are used to prevent the spring 26 from shaking when it is squeezed, ensuring that the scraper 27 is always in a vertical position, while not affecting the deformation of the spring 26. The spring 26 is sleeved on the surface of the sleeve 24. The spring 26 is used to maintain a constant contact pressure between the scraper 27 and the screen 11, which can effectively clean asphalt particles and avoid damage to the screen 11. The end of the sliding rod 25 away from the sleeve 24 is fixedly connected to the scraper 27. The scraper 27 is used to scrape off the asphalt particles that are adhering and clogging the screen 11, so that the particles are detached from the screen 11, thereby preventing asphalt particles from clogging the screening machine and affecting its normal operation. The drive motor 2 intermittently drives the scraper 27 to move. The drive motor 2 is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here.

[0029] Furthermore, the limiting mechanism includes a placement plate 3, which is fixedly connected to the surface of the screening machine body 1. The placement plate 3 is used to place and support the receiving frame. An abutment plate 31 is fixedly connected to the upper surface of the placement plate 3. The abutment plate 31 is used to abut against one side of the receiving frame, thereby achieving clamping and limiting of the receiving frame. A support plate 32 is fixedly connected to the upper surface of the placement plate 3. The support plate 32 is used to support the screw 33. The surface of the support plate 32 is threaded with the screw 33. The screw 33 is used to drive the limiting plate 35 to move and clamp and limit the receiving frame, thereby improving the receiving efficiency. To ensure the stability of the receiving frame and prevent displacement of the receiving frame due to external impact during material receiving, thus avoiding asphalt particles falling to the ground and causing pollution, a movable plate 34 is fixedly connected to the surface of the screw 33. The movable plate 34 is used to prevent the limiting plate 35 from affecting the rotation of the screw 33. The limiting plate 35 is movably connected to the surface of the movable plate 34 and is used to clamp and limit the receiving frame, thereby improving the placement stability of the receiving frame and preventing displacement of the receiving frame due to external impact during material receiving, thus avoiding asphalt particles falling to the ground and causing pollution.

[0030] Furthermore, the drive motors 2 are symmetrically distributed in two groups on the surface of the screening machine body 1. The drive motors 2 are used to drive the rotating rollers 21 to rotate. The two sets of drive motors 2 operate synchronously. The rotating rollers 21 are rotatably connected to the screening machine body 1 through the drive motors 2. The rotating rollers 21 are used to drive the lead screw 22 to rotate. The two sets of rotating rollers 21 rotate synchronously.

[0031] Furthermore, the lead screw 22 is rotatably connected to the screening machine body 1 via the rotating roller 21. The lead screw 22 is used to drive the moving plate 23 to drive the scraper 27 to reciprocate. The movement of the scraper 27 can scrape off the asphalt particles that are stuck to the screen 11, so that the particles can be removed from the screen 11, thereby preventing the asphalt particles from clogging and affecting the normal use of the screening machine. The threads of the two sets of lead screws 22 are the same. The moving plate 23 is slidably connected to the screening machine body 1 via the lead screw 22. The moving plate 23 is used to drive the scraper 27 to reciprocate. The movement of the scraper 27 can scrape off the asphalt particles that are stuck to the screen 11, so that the particles can be removed from the screen 11, thereby preventing the asphalt particles from clogging and affecting the normal use of the screening machine.

[0032] Furthermore, the sleeves 24 are evenly distributed in five groups on the upper surface of the moving plate 23, and the slide rod 25 is composed of two cylinders with different radii. The sleeves 24 and slide rod 25 are used to prevent the spring 26 from shaking when it is squeezed, to ensure that the scraper 27 is always in a vertical state, and at the same time, to not affect the deformation of the spring 26.

[0033] Furthermore, the two ends of the spring 26 are fixedly connected to the moving plate 23 and the scraper 27 respectively. The spring 26 is used to maintain a constant contact pressure between the scraper 27 and the screen 11, which can effectively clean asphalt particles and avoid damage to the screen 11. The scraper 27 is slidably connected to the screen 11 through the moving plate 23. The scraper 27 is used to scrape off the asphalt particles that are stuck to the screen 11, so that the particles are removed from the screen 11, thereby avoiding the asphalt particles from blocking the screen and affecting the normal use of the screening machine. The drive motor 2 intermittently drives the scraper 27 to move.

[0034] Furthermore, the placement plate 3 is used to place and support the receiving frame. The abutment plate 31 is used to abut against one side of the receiving frame, thereby achieving clamping and limiting of the receiving frame. The support plate 32 is used to support the screw 33. The screw 33 is movably connected to the limiting plate 35 through the movable plate 34. The screw 33 is used to drive the limiting plate 35 to move and clamp and limit the receiving frame, thereby improving the placement stability of the receiving frame and preventing the receiving frame from being displaced by external force collision during the receiving process, which would cause asphalt particles to fall to the ground and cause pollution. The movable plate 34 is circular and is used to ensure that the limiting plate 35 does not affect the rotation of the screw 33. The limiting plate 35 is slidably connected to the placement plate 3 through the screw 33. The limiting plate 35 is used to clamp and limit the receiving frame, thereby improving the placement stability of the receiving frame and preventing the receiving frame from being displaced by external force collision during the receiving process, which would cause asphalt particles to fall to the ground and cause pollution.

[0035] Working principle: During the screening process, the drive motor 2 drives the rotating roller 21 and the lead screw 22 to rotate, which in turn drives the moving plate 23 to drive the scraper 27 to reciprocate. The movement of the scraper 27 can scrape off the asphalt particles that are stuck on the screen 11, so that the particles can be removed from the screen 11, thereby avoiding the asphalt particles from clogging and affecting the normal use of the screening machine.

[0036] Two receiving frames are placed on the placement plate 3. Then, rotating the screw 33 can drive the limiting plate 35 to move and clamp the receiving frames, thereby improving the placement stability of the receiving frames and preventing the receiving frames from being displaced by external force collisions during the receiving process, which would cause asphalt particles to fall to the ground and cause pollution to the asphalt particles.
