[0001] This utility model relates to the technical field of drum screening machines, specifically to a drum screening machine for tire pulverization. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance. After waste tires are pulverized, a drum screen is used to screen the pulverized tire pieces. The drum screen is a widely used machine in sorting technology. It controls the sorting of materials by the size of the particles and has high sorting accuracy. The drum screen is generally divided into several sections, depending on the specific situation. The screen holes are arranged from small to large, and the screen hole diameter is the same on each section.

[0003] The feeding method of existing drum screens is relatively simple, mostly using direct feeding. The material enters the drum screen directly through the feed hopper. The material is prone to accumulate at the inlet of the drum screen, causing blockage and affecting the normal operation of the drum screen. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a drum screening machine for tire pulverization, which has the following beneficial effects:

[0015] In this invention, compared to the relatively simple feeding method of existing drum screens, which mostly use direct feeding where materials enter directly into the drum screen through the feed hopper, materials tend to accumulate at the inlet, causing blockages and affecting the normal operation of the drum screen. This invention addresses this problem by using a conveying bin and threaded conveying rollers to guide and transport the material falling into the feed hopper. Furthermore, the combination of guide columns, a striking mechanism, and first and second return springs enables repeated striking of the conveying bin. Therefore, after being compacted, the material in this drum screen can fall orderly through the discharge port on the conveying bin into the main body of the drum screen, reducing the probability of material accumulation at the feed inlet, ensuring the normal operation of the drum screen, guaranteeing smooth material transport within the conveying bin, and minimizing the probability of material blockage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example

[0025] Please see Figures 1 to 5 This embodiment proposes a drum screening machine for tire pulverization, including a drum screening machine body 1, a support base 2, and a feed hopper 3. The drum screening machine body 1 is inclined, the support base 2 is installed on the upper side of the support frame on the drum screening machine body 1, and the feed hopper 3 is installed on the upper side of the support base 2. It also includes a conveying bin 4, a baffle 5, a mounting plate 6, a threaded conveying roller 7, a protective cover 8, a guide column 9, a striking mechanism, a first return spring 10, and a second return spring 11. Compared with the relatively simple feeding method of existing drum screening machines, most of which adopt direct feeding, the material enters the drum screening machine directly through the feed hopper. The material is prone to accumulate at the inlet of the drum screening machine, causing the drum screening machine to... The blockage at the inlet affects the normal operation of the drum screener. In this embodiment, the cooperation of the conveying bin 4 and the threaded conveying roller 7 is used to guide and convey the material falling into the feed hopper 3, so that the material can fall into the drum screener body 1 in an orderly manner through the discharge port opened on the conveying bin 4. This reduces the probability of material accumulating at the feed port of the drum screener body 1 and ensures the normal operation of the drum screener body 1. Through the cooperation of the guide column 9, the striking mechanism, the first return spring 10 and the second return spring 11, the conveying bin 4 is repeatedly struck, which ensures the smooth conveying of material inside the conveying bin 4 and reduces the probability of material blocking the conveying bin 4.

[0026] like Figure 1As shown, a first conveying mechanism 13 and a second conveying mechanism 14 are respectively arranged on both sides of the main body 1 of the drum screener. A briquetting machine 15 is arranged on the other side of the first conveying mechanism 13. The feeding side of the first conveying mechanism 13 is below the briquetting machine 15, and the discharging side of the first conveying mechanism 13 is above the feed hopper 3. The feeding side of the second conveying mechanism 14 is below the discharging side of the main body 1 of the drum screener.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the conveying bin 4 is installed on the side of the feed hopper 3 near the main body 1 of the drum screen and is connected to the feed hopper 3. A discharge port is provided on the lower side of the conveying bin 4. A baffle 5 is installed inside the conveying bin 4. The baffle 5 can block the material above the discharge port, ensuring that the material can fall into the main body 1 of the drum screen through the discharge port. Figure 4 As shown, the mounting plate 6 is installed inside the conveying bin 4. Multiple threaded conveying rollers 7 are rotatably mounted on one side of the mounting plate 6. The multiple threaded conveying rollers 7 are connected by multiple transmission components. The mounting plate 6 is provided with a driving component for driving the threaded conveying rollers 7 located in the middle to rotate. The multiple threaded conveying rollers 7 are rotatably mounted on the mounting plate 6 in a parallel manner. The multiple threaded conveying rollers 7 together guide and convey the material falling into the feed hopper 3, so that the material can move evenly inside the conveying bin 4, ensuring the smoothness of material conveying and reducing the probability of material accumulating at the feed point of the drum screen body 1.

[0028] like Figure 3 and Figure 5As shown, the protective cover 8 is installed on the upper side of the conveying chamber 4. Multiple guide posts 9 are installed on the inner top wall of the protective cover 8. The striking mechanism is sleeved on the guide posts 9. The striking mechanism includes a sliding plate 101, a connecting plate 102, a striking seat 103, and a vibration motor 104. Slide rails 12 are installed on both sides of the inner wall of the protective cover 8. The sliding plate 101 is slidably connected to the slide rails 12. The slide rails 12 can limit the sliding of the sliding plate 101, ensuring the stability of the sliding plate 101 during sliding. A buffer pad is provided on the lower side of the striking seat 103. The buffer pad can buffer the impact between the striking seat 103 and the conveying chamber 4, preventing direct collision between the striking seat 103 and the conveying chamber 4. Multiple reinforcing rods are installed on both sides of the connecting plate 102 for reinforcement. The rod is L-shaped, with the upper end of the reinforcing rod connected to the lower side of the sliding plate 101. The reinforcing rod can reinforce the sliding plate 101 and the connecting plate 102, enhancing the firmness of the installation between the sliding plate 101 and the connecting plate 102. The first return spring 10 is sleeved on the upper part of the outer side of the guide post 9, and the two ends of the first return spring 10 are connected to the striking mechanism and the protective cover 8, respectively. The second return spring 11 is sleeved on the lower part of the outer side of the guide post 9, and the two ends of the second return spring 11 are connected to the striking mechanism and the conveying chamber 4, respectively. The cooperation of the guide post 9, the striking mechanism, the first return spring 10 and the second return spring 11 can realize repeated striking of the conveying chamber 4, thereby reducing the probability of material blockage in the conveying chamber 4.

[0029] Working principle:

[0030] The material processed by the briquetting machine 15 falls onto the first conveying mechanism 13. The first conveying mechanism 13 conveys the material into the feed hopper 3. After the material enters the feed hopper 3, the forward and reverse motor is started. The forward and reverse motor drives the threaded conveying roller 7 located in the middle to rotate. The threaded conveying roller 7 located in the middle drives the other threaded conveying rollers 7 to rotate through the transmission component. The multiple threaded conveying rollers 7 guide and convey the material falling into the feed hopper 3. The conveyed material falls into the main body 1 of the drum screening machine through the discharge port. At the same time as the threaded conveying rollers 7 convey the material, the vibration motor 104 is started. The vibration motor 104 operates... The generated vibration force drives the sliding plate 101 to slide along the slide rail 12 and the guide post 9. Under the action of the first return spring 10 and the second return spring 11, the sliding plate 101 drives the striking seat 103 to repeatedly strike the conveying chamber 4 through the connecting plate 102, which reduces the probability of material blockage in the conveying chamber 4. After the material falls into the body 1 of the drum screener, the body 1 of the drum screener screens the material. Smaller material particles are screened off to the ground by the body 1 of the drum screener, while the remaining large materials fall onto the second conveying mechanism 14 through the body 1 of the drum screener, and are then conveyed to the corresponding position by the second conveying mechanism 14.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
