Description

Technical Field

[0001] This utility model relates to the field of cement concrete surface layer technology, specifically to a raw material mixing device for cement concrete surface layer. Background Technology

[0002] Cement concrete pavement refers to road surfaces made primarily of cement concrete, also known as rigid pavement or white pavement, and is a type of high-grade pavement. Types include plain concrete, reinforced concrete, continuously reinforced concrete, and prestressed concrete. Structural composition: Cement concrete pavement structures include subgrade, subbase, base course, and surface course. Construction requirements: Raw materials must be strictly controlled, such as cement grade, coarse aggregate particle size, and sand fineness modulus. During construction, formwork selection, paving, vibration compaction, and joint treatment must all meet specifications. Before concrete construction, the design mix proportions must be checked for suitability; if not, adjustments must be made promptly.

[0003] During the construction of cement concrete pavement, mixing equipment is required to mix materials. Currently, a single mixing rod is used for mixing. However, the range of action of a single mixing rod is limited, making it difficult to fully cover the entire mixing area. This results in some materials not being fully mixed, which can easily lead to clumping. Since there is only one mixing rod, its mixing force and speed are also relatively limited, making it impossible to mix the materials with high intensity. The mixing effect is poor, which reduces the effectiveness of subsequent construction.

[0004] Therefore, it is necessary to redesign and modify the mixing equipment to effectively prevent the current practice of using a single mixing rod, which results in poor mixing effect and easy material clumping. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a raw material mixing device for cement concrete surface layer, which has the advantage of high-efficiency mixing and solves the problem that the current method of mixing with a single mixing rod results in poor mixing effect and easy material clumping.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a raw material mixing device for cement concrete surface layer, comprising a concrete raw material mixing device body, a feed hopper fixedly installed on the top of the concrete raw material mixing device body, a linkage component provided on the left side of the concrete raw material mixing device body, a transmission component fixedly installed on the front side of the left side of the concrete raw material mixing device body, and a discharge pipe connected to the right side of the concrete raw material mixing device body.

[0007] In a preferred embodiment of this invention, the linkage component includes a support rod that is laterally movably connected inside the concrete raw material mixing device body. A mixing blade is fixedly connected to the surface of the support rod, and the left side of the support rod extends through to the left side of the concrete raw material mixing device body. A mating gear is fixedly connected to the left side of the support rod surface.

[0008] In a preferred embodiment of this invention, the transmission assembly includes a bracket, which is fixedly connected to the left side of the front of the concrete raw material mixing device body. A motor is fixedly connected to the left side of the bracket, and a worm gear is fixedly connected to the output end of the motor. A worm wheel that meshes with the worm gear is fixedly connected to the surface of the support rod.

[0009] As a preferred embodiment of this invention, a limiting plate is fixedly connected to the left side of the concrete raw material mixing device body, and the limiting plate is movably connected to the back of the worm gear.

[0010] As a preferred embodiment of this utility model, a protective cover is fixedly connected to the left side of the concrete raw material mixing device body, and the protective cover is located outside the mating gear.

[0011] As a preferred embodiment of this invention, the inside of the feed hopper is fixedly connected with a number of unblocking rods.

[0012] As a preferred embodiment of this invention, a stirring rod is fixedly connected to the surface of the support rod, and the number of stirring rods is several.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves adding raw materials into the interior of the concrete raw material mixing device. The user then starts the motor, which drives the worm gear to rotate. The worm gear drives the worm wheel to rotate, which in turn drives the support rod to rotate. The support rod then drives the mating gear to rotate, causing the two support rods to drive the mixing blades to mix the raw materials thoroughly. Simultaneously, the mixing rod rotates, further mixing the raw materials and achieving a thorough mixing effect. This replaces the existing method of using three mixing rods, thus facilitating a more thorough mixing process.

[0015] 2. This utility model, through the setting of the linkage component, can transmit power to the support rod, which can ensure that the support rod drives the mixing blade to rotate, with strong stability and ease of use for users. Attached Figure Description

A mixing blade 32 is fixedly connected to the surface of the support rod 31. The left side of the support rod 31 extends through to the left side of the concrete raw material mixing device body 1. A mating gear 33 is fixedly connected to the left side of the surface of the support rod 31.

[0024] As a technical optimization of this utility model, the linkage component 3 can be used to drive the support rod 31, which can ensure that the support rod 31 drives the mixing blade 32 to rotate. This results in strong stability and ease of use for users.

[0025] refer to Figure 4The transmission component 4 includes a bracket 41, which is fixedly connected to the left side of the front of the concrete raw material mixing device body 1. A motor 42 is fixedly connected to the left side of the bracket 41. A worm gear 43 is fixedly connected to the output end of the motor 42. A worm wheel 44 that meshes with the worm gear 43 is fixedly connected to the surface of the support rod 31.

[0026] As a technical optimization of this utility model, the transmission component 4 can transmit power to the worm gear 43, ensuring the stability of the worm gear 43 and enabling it to rotate and transmit power normally, making it convenient for users to use.

[0027] refer to Figure 4 A limiting plate 6 is fixedly connected to the left side of the concrete raw material mixing device body 1, and the limiting plate 6 is movably connected to the back of the worm gear 43.

[0028] As a technical optimization of this utility model, the limiting plate 6 can limit the worm gear 43, so that the worm gear 43 can rotate stably and is not prone to tilting, making it convenient for users to use.

[0029] refer to Figure 2 A protective cover 7 is fixedly connected to the left side of the concrete raw material mixing device body 1, and the protective cover 7 is located outside the mating gear 33.

[0030] As a technical optimization of this utility model, the protective cover 7 can protect the mating gear 33, which is highly safe and can prevent damage to the mating gear 33, making it convenient for users to use.

[0031] refer to Figure 4 The feed hopper 2 is fixedly connected with a dredging rod 8, and there are several dredging rods 8.

[0032] As a technical optimization of this utility model, the unblocking rod 8 can unblock the material entering the top of the feed hopper 2, avoiding blockage caused by large pieces of material, and making it convenient for users to use.

[0033] refer to Figure 4 A stirring rod 9 is fixedly connected to the surface of the support rod 31, and there are several stirring rods 9.

[0034] As a technical optimization of this utility model, the stirring rod 9 can be used in conjunction with the stirring blade, which has excellent functionality, good mixing effect, and can fully mix and disperse the particles.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to mix concrete raw materials, firstly, the raw materials are added into the body 1 of the concrete raw material mixing device. Then, the user starts the motor 42. At this time, the motor 42 starts to run, and its output end drives the worm 43 to rotate. The worm 43, as an important transmission component, has a unique spiral shape. Its rotational motion can effectively transmit power. The rotation of the worm 43 will drive the worm wheel 44 to rotate. The worm wheel 44 usually cooperates with the worm 43 and has a large transmission ratio. It can convert the high-speed rotation of the worm 43 into a slower but more torque-enhanced rotational motion. The worm wheel 44 drives the support rod 31 to rotate. Under the drive of the worm wheel 44, the support rod 31 begins to rotate stably. The rotation of the support rod 31 further drives the mating gear 33 to rotate. In this process, the two support rods 31 can work together to drive the mixing blades 32 to mix the concrete raw materials. The rotation of the mixing blades 32 enables the raw materials to be continuously turned over and stirred inside the concrete raw material mixing device body 1, thereby achieving a thorough mixing effect. At the same time, the rotation of the support rod 31 will also drive the stirring rod 9 to rotate. The function of the stirring rod 9 is to further enhance the stirring of the mixed raw materials. It can penetrate into different layers of the raw materials, making the mixing more uniform and thorough. Through the combined action of the mixing blades 32 and the stirring rod 9, the concrete raw materials can be mixed in all directions and from multiple angles, thereby achieving a thorough mixing effect.

[0036] In summary, this raw material mixing device for cement concrete surface layers solves the problem of poor mixing effect and material clumping that currently only uses a single mixing rod for mixing. This is achieved through the coordinated use of the concrete raw material mixing device body 1, feeding hopper 2, linkage component 3, support rod 31, mixing blade 32, cooperating gear 33, transmission component 4, bracket 41, motor 42, worm gear 43, worm wheel 44, discharge pipe 5, limit plate 6, and protective cover 7.
