Description

Technical fields:

[0001] This utility model relates to the field of road-mixed cement mixing, specifically to a mixing rotor for road-mixed cement made from aeolian sand. Background technology:

[0002] In highway construction projects, the mixing of aeolian sand with cement is a crucial step, playing a key role in ensuring the quality of the road base. However, in confined spaces used for aeolian sand mixing, traditional stabilized soil mixing machines are often difficult to operate due to their large size and limited space requirements, failing to meet construction needs. Such confined construction environments are common in rural roads, mountain roads, and other special road sections where space is limited, making it difficult for large equipment to enter or carry out its work.

[0003] Existing mixing equipment is either unable to enter narrow construction sites, or even if it is forced to operate, it will result in low construction efficiency and difficulty in ensuring mixing quality due to inconvenience. It is impossible to achieve uniform mixing of cement and aeolian sand, which in turn affects the stability and durability of the road base. Utility model content:

[0004] To address this issue, this utility model provides a mixing rotor for mixing cement in aeolian sand road construction, which overcomes the problems of existing mixing equipment in narrow construction scenarios. These equipment either cannot enter the site or, even if they are forced to operate, suffer from low construction efficiency and difficulty in ensuring mixing quality due to inconvenient operation. Consequently, they cannot achieve uniform mixing of cement and aeolian sand, thus affecting the stability and durability of the road base.

[0005] This utility model is implemented by the following technical solution:

[0006] A mixing rotor for mixing cement on a wind-blown sand road includes a rotor shaft, cutter discs, and bent blades. The cutter discs are evenly distributed and fixedly installed along the length of the rotor shaft. The bent blades are detachably installed on the cutter discs, and the bent blades on adjacent cutter discs have opposite bending directions. An auxiliary connecting plate is fixed to the bending point of the bent blade, and the two ends of the auxiliary connecting plate are welded to the bending point of the bent blade. A dust cover is provided above the rotor shaft, and the side end of the rotor shaft extends out of the dust cover and is connected to a hydraulic motor through a chain drive mechanism.

[0007] Preferably, the auxiliary connecting plate is made of high-strength steel and is customized according to the shape and size of the bending part of the elbow blade.

[0008] Preferably, the outer side of the cutter head is provided with a plurality of mounting sleeves arranged in a ring, and the side end of the bent blade is inserted into the mounting sleeve in close contact with it. The mounting sleeve and the side end of the bent blade are connected by bolts, and then fastened with nuts.

[0009] Preferably, the dust cover is positioned corresponding to the rotor shaft and covers the area above the rotor shaft.

[0010] Preferably, the chain drive mechanism includes a driving sprocket, a driven sprocket, and a chain. The driving sprocket is connected to a hydraulic motor, and the driven sprocket is connected to the side end of the rotor shaft that extends out of the dust cover.

[0011] The advantages of this invention are as follows: The design, centered on the mixing rotor of an agricultural rotary tiller, adapts to the needs of mixing aeolian sand on narrow roads, achieving significant results and enabling smooth construction even in complex terrain. The equipment uses a tractor-powered motor, simplifying operation, reducing installation and debugging time and costs, and improving construction efficiency. Through its unique rotor structure, including a uniformly distributed cutter head, detachable curved blades, and auxiliary connecting plates, it achieves efficient mixing of aeolian sand and cement. The curved blades quickly cut into the aeolian sand layer, and the auxiliary connecting plates alter the material's trajectory, ensuring uniform mixing, improving the quality of cement-stabilized soil, guaranteeing the quality of road base construction, and laying the foundation for long-term stable road use.

[0016] 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.

[0017] like Figure 1 , Figure 2 As shown, the mixing rotor for cement mixing on wind-blown sand roads mainly consists of a rotor shaft 1, a cutter head 2, bent blades 3, an auxiliary connecting plate 4, a dust cover 5, a chain drive mechanism 6, and an oil motor 7. All components work together to achieve efficient mixing.

[0018] The rotor shaft 1 is the core supporting component of the entire mixing system, providing stable support for equipment operation. The cutter heads 2 are evenly distributed and fixedly installed along the length of the rotor shaft 1, serving as the load-bearing base for the bent blades 3. The bent blades 3 are detachably installed on the cutter heads 2 and are key working components for mixing soil and cement. Multiple mounting sleeves are distributed in a ring on their outer surface. After one end of the bent blade 3 is inserted into a sleeve, bolts are used to pass through the mounting sleeve and the bent blade 3, and then nuts are tightened to ensure a secure connection and easy disassembly and replacement. The bent blades 3 installed on adjacent cutter heads 2 have opposite bending directions; this design helps improve the uniformity and efficiency of mixing.

[0019] The auxiliary connecting plate 4 is made of high-strength steel and is customized according to the shape and size of the bend in the elbow blade 3. Both ends are directly welded to the bend in the blade to ensure a firm and reliable connection during mixing and prevent loosening. The dust cover 5 covers the rotor shaft 1, effectively blocking dust and material splashes during mixing and maintaining a clean construction site environment. The chain drive mechanism 6 consists of a drive sprocket, a driven sprocket, and a chain. The drive sprocket is connected to the hydraulic motor 7, and the driven sprocket is connected to the side end of the rotor shaft 1 that extends out of the dust cover 5. Power is output through the hydraulic motor 7 and driven by the chain to rotate the rotor shaft 1, the cutter head 2, and the elbow blade 3.

[0020] Actual work process:

[0021] In narrow, wind-blown sand road construction scenarios, if a stabilized soil mixing machine cannot be used, a mixing rotor similar to that of an agricultural rotary tiller can be employed. During construction, cement is first evenly spread on the construction surface using a specific conveying device, and then the hydraulic motor 7 (or a tractor-powered motor) is started.

[0022] The torque output by the oil motor 7 is transmitted to the rotor shaft 1 via the chain drive mechanism 6, driving the rotor shaft 1 to rotate at high speed, and the cutter head 2 rotates synchronously accordingly.

[0023] As the cutter head 2 rotates, the bent blades 3 cut into the aeolian sand layer, chopping and lifting the soil. At this time, the auxiliary connecting plate 4 connected to the bend of the bent blades 3 plays a key role. Due to its unique position and shape, it changes the trajectory of the material movement, pushing the chopped soil and cement to make complex relative movements in the mixing space, thus achieving a mixing effect.

[0024] The auxiliary connecting plate 4 pushes the material close to the blade away from the blade, causing the materials to collide and mix with each other, thus achieving full mixing of soil and cement in three-dimensional space.

[0025] The dust cover 5 effectively blocks dust and materials from escaping throughout the mixing process, reducing the impact on the surrounding environment and personnel.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
