[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A screed for an asphalt paver in construction engineering includes a screed body 1 and several fixed posts 2. A baffle mechanism 3 is provided at the bottom of the screed body 1, and a locking block 4 is provided on both sides of the screed body 1.

[0030] The partition mechanism 3 includes two first connecting blocks 301, several limiting blocks 302, two arc plates 303 and a pressure plate 304. The side of the first connecting block 301 near the pressure plate 304 is fixedly connected to the pressure plate 304. The bottom of the limiting block 302 is fixedly connected to the top of the arc plate 303. The side of the arc plate 303 near the pressure plate 304 is fixedly connected to the pressure plate 304.

[0031] In this embodiment: the partition mechanism 3 is connected to the screed body 1 by a snap-fit ​​limiting pin 6. The insert 14 of the clip 4 is inserted into the connecting block slot 13, and the limiting pin 6 is fixed through. The top magnetic block 7 is magnetically reinforced. When cleaning the pressure plate 304 and the arc plate 303, pull the pull block 8 to separate the magnetic block 7, pull out the limiting pin 6, and then pull the pull ring 5 to disassemble. The installation is done in reverse. This solves the problem that some existing asphalt paver screeds are inconvenient to disassemble, which makes it difficult to clean the asphalt adhering to the surface of the asphalt paver screed. The protective layer 9 consists of a primer layer 90. 1. Composed of anti-corrosion layer 902 and wear-resistant layer 903, the inorganic zinc-rich primer provides adhesion and rust prevention, the polyimide coating is resistant to high temperature and corrosion, and the ceramic-based composite coating is wear-resistant. The three layers work together to protect the components, extend their service life, and indirectly protect the screed body 1. The screed body 1 is connected to the external asphalt paver through the fixing column 2. The pressure plate 304 is inlaid with high-purity copper heat-conducting strips 11. During operation, the heat from the heating system of the asphalt paver is conducted through the screed body 1, and the heat-conducting strips 11 quickly and evenly transfer heat, preventing the asphalt mixture from solidifying prematurely at the bottom of the pressure plate 304 and ensuring smooth paving.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the limiting blocks 302 are evenly distributed on the surface of the arc plate 303. The surface of the limiting blocks 302 is in active contact with the surface of the ironing plate body 1. Pull rings 5 ​​are fixedly connected to the front and rear sides of the left side of the pressure plate 304.

[0033] Specifically, such as Figure 4 As shown, the top of the pressure plate 304 is provided with an embedding groove 10. There are several embedding grooves 10 and they are evenly distributed on the top of the pressure plate 304. The inner wall of the embedding groove 10 is tightly inlaid with a heat-conducting strip 11.

[0034] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, the ironing board body 1 has a second connecting block 12 fixedly connected to both sides. The first connecting block and the second connecting block 12 have slots 13 inside. The top and bottom sides of the inner wall of the card block 4 are fixedly connected to the insert strips 14, which are movably inserted into the slots 13.

[0035] Specifically, such as Figure 1 and Figure 3As shown, a limiting pin 6 is provided at the top of the card block 4, and the bottom of the limiting pin 6 passes through the card block 4, the second connecting block 12 and the first connecting block 301 in sequence and extends to the outside of the card block 4.

[0036] Specifically, such as Figure 1 and Figure 3 As shown, a magnetic block 7 is fixedly connected to the top of the limiting pin 6, the bottom of the magnetic block 7 is magnetically attracted to the top of the card block 4, and a pull block 8 is fixedly connected to the front and rear sides of the magnetic block 7.

[0037] In this embodiment: by contacting the limiting block 302 with the surface of the screed body 1, the pressure plate 304 and the arc plate 303 can be easily connected to the screed body 1. By embedding the heat-conducting strip 11 inside the embedding groove 10, the heat of the asphalt paver can be quickly and evenly transferred to the inside of the pressure plate 304 and the arc plate 303. After connecting the pressure plate 304 and the arc plate 303 to the screed body 1, the insert strip 14 on the inner wall of the card block 4 is inserted into the slot 13 to connect the first connecting block 301 and the second connecting block 12. Then, the limiting pin 6 passes through the card block 4, the second connecting block 12 and the first connecting block 301, so that the bottom of the magnetic block 7 is magnetically attracted to the top of the card block 4, which can conveniently limit the screed body 1 to the pressure plate 304 and the arc plate 303 together.

[0038] Specifically, such as Figure 6 As shown, both the pressure plate 304 and the curved plate 303 are provided with a protective layer 9. The protective layer 9 includes a primer layer 901, an anti-corrosion layer 902, and a wear-resistant layer 903. The primer layer 901 is uniformly coated on the surface of the pressure plate 304. The primer layer 901 is made of inorganic zinc-rich primer. The anti-corrosion layer 902 is uniformly coated on the surface of the primer layer 901. The anti-corrosion layer 902 is made of polyimide coating. The wear-resistant layer 903 is uniformly coated on the surface of the anti-corrosion layer 902. The wear-resistant layer 903 is made of ceramic-based composite coating.

[0039] Specifically, such as Figure 4 As shown, the heat-conducting strip 11 is made of high-purity copper.

[0040] In this embodiment, the protective layer 9 consists of a primer layer 901, an anti-corrosion layer 902, and a wear-resistant layer 903. The inorganic zinc-rich primer provides adhesion and rust prevention, the polyimide coating is resistant to high temperature and corrosion, and the ceramic-based composite coating is wear-resistant. The three layers work together to protect the components, extend their service life, and indirectly protect the ironing plate body 1. The high-purity copper heat-conducting strip 11 can make the heat-conducting strip 11 have better thermal conductivity.

[0041] Working principle: The partition mechanism 3, composed of the pressure plate 304 and the arc plate 303, is connected to the ironing plate body 1 by a snap-fit ​​limiting pin 6. The locking block 4 is inserted into the slot 13 of the first connecting block 301 and the second connecting block 12 through the insert 14, and then the limiting pin 6 is inserted through the locking block 4, the second connecting block 12 and the first connecting block 301. The top magnetic block 7 magnetically attracts the locking block 4 to fix the limiting pin 6. When asphalt adheres to the surface of the pressure plate 304 and the arc plate 303 and needs to be cleaned, the pull block 8 is pulled to separate the magnetic block 7 from the locking block 4, the limiting pin 6 is pulled out, and the pull ring 5 is pulled to make the limiting block... Separating 302 from the screed body 1 allows the pressure plate 304 and arc plate 303 to be removed from the screed body 1. After cleaning, the reverse operation can be performed for reinstallation. This solves the problem of inconvenience in disassembling some existing asphalt paver screeds, which makes it difficult to clean the asphalt adhering to the surface of the asphalt paver screed. The protective layer 9 consists of a primer layer 901, an anti-corrosion layer 902, and a wear-resistant layer 903. The primer layer 901, composed of inorganic zinc-rich primer, is coated on the surface of the pressure plate 304. Due to its good adhesion, it lays the foundation for subsequent coatings. The base layer, while possessing a certain degree of rust prevention, has a polyimide coating anti-corrosion layer 902 applied over the primer layer 901. This layer is heat-resistant and corrosion-resistant, protecting the primer layer 901. A ceramic-based composite coating wear-resistant layer 903 is applied to the surface of the anti-corrosion layer 902. With its high hardness and wear resistance, it resists friction during asphalt paving. These three layers work together to extend the service life of the pressure plate 304 and the curved plate 303. Furthermore, the pressure plate 304 and the curved plate 303 directly protect the screed body 1, further improving its service life. The fixing post 2 at the top of the screed body 1... Used for connection with external asphalt pavers, the top of the pressure plate 304 has an embedded groove 10, inlaid with a heat-conducting strip 11 made of high-purity copper. When the screed is working, the heating system of the asphalt paver generates heat, which is conducted through the screed body 1. The heat-conducting strip 11, with its excellent thermal conductivity, quickly and evenly transfers heat to the surface of the pressure plate 304 and the curved plate 303, preventing the asphalt mixture from solidifying too quickly at the bottom of the pressure plate 304 and ensuring the smooth progress of asphalt paving. It should be noted that the asphalt paver is a mature technology that has been published and will not be described in detail here.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
