Description
Technical Field
[0001] This utility model relates to the technical field of cement production equipment, and in particular to a cement bar sand and gravel mixing device. Background Technology
[0002] In the field of infrastructure construction, cement poles serve as the core supporting structure for urban streetlights, traffic lights, power transmission, and other applications, and their quality directly affects the safety and durability of public facilities. The main components of cement poles are steel reinforcement and concrete, with the mixing quality of the concrete being a key factor determining the strength, crack resistance, and service life of the cement pole.
[0003] The preparation of concrete mixtures requires the uniform mixing of raw materials such as cement, aggregates, water, and admixtures, and the mixing device is the core equipment for achieving this process. Currently, most mixing devices widely used in the industry adopt the traditional structure of single-shaft driven stirring rod rotation. This mixing method has significant limitations. The unidirectional stirring trajectory causes the raw materials to easily form a fixed circulation, making it difficult to break up material agglomeration. Local areas are prone to mixing dead zones, resulting in uneven mixing of aggregates and cement paste, which directly affects the homogeneity and strength of the concrete.
[0004] In addition, traditional mixing devices often encounter problems such as raw material sedimentation and discharge residue in the material conveying and discharging process, which not only reduces mixing efficiency but may also cause secondary problems such as equipment scaling and corrosion due to material retention. Utility Model Content
[0005] This utility model aims to at least partially solve one of the technical problems in the related art.
[0006] Therefore, one objective of this utility model is to provide a cement bar sand and gravel mixing device that enhances material flowability and mixing effect through dual-shaft reverse stirring combined with reverse screw conveying, while assisting in material discharge and improving concrete mixing quality and discharge efficiency.
[0007] To achieve the above objectives, a first aspect of this utility model provides a cement-pole aggregate mixing device, comprising a cylinder, an inlet pipe, an outlet pipe, and a mixing mechanism, wherein...
[0008] The feed pipe is connected to the top surface of the cylinder, the discharge pipe is connected to the bottom surface of the cylinder, and the mixing mechanism is located inside the cylinder.
[0009] The mixing mechanism includes a stirring component and an auxiliary component. The stirring component is disposed inside the cylinder, and the auxiliary component is disposed on the surface of the stirring component.
[0010] The cement rod sand and gravel mixing device of this utility model introduces the raw materials into the inside of the cylinder. By starting the motor, the connecting shaft connected to it is rotated. Then, under the combined action of the first bevel gear and the second bevel gear, the other connecting shaft is rotated in the opposite direction. This, together with the stirring rod, achieves stirring in two directions, effectively improving the mixing effect. Furthermore, under the combined action of the first transmission mechanism and the second transmission mechanism, the two mounting shafts can be driven to rotate synchronously. During this process, two conveying flows with different directions can be formed on the raw materials inside the cylinder. This enhances the fluidity of the internal raw materials and, together with the stirring rod, greatly improves the mixing effect of the internal raw materials. In addition, the spiral conveying plate at the bottom can assist the material inside the cylinder to move towards the discharge pipe during the material discharge process, facilitating the discharge.
[0011] In addition, the cement pole sand and gravel mixing device proposed above according to this utility model may also have the following additional technical features:
[0012] In one embodiment of this utility model, the stirring assembly includes two connecting shafts, a protective shell, several stirring rods, and a motor, wherein,
[0013] The protective shell is located at the center of the cylinder, the two connecting shafts are respectively located at both ends of the protective shell, the motor is located on one side of the cylinder, one end of one connecting shaft passes through the cylinder and is fixedly connected to the output shaft of the motor, the other end of the other connecting shaft is rotatably connected to the inner wall of the cylinder, and several stirring rods are fixedly connected to the surfaces of the two connecting shafts and are evenly distributed.
[0014] In one embodiment of this utility model, a mounting rod is fixedly connected to the surface of the protective shell, the other end of the mounting rod is fixedly connected to the inner wall of the cylinder, and a second bevel gear is rotatably connected to the inner wall of the protective shell.
[0015] In one embodiment of this utility model, the opposite ends of the two connecting shafts both penetrate the protective shell and are fixedly connected to a first bevel gear that meshes with the second bevel gear.
[0016] In one embodiment of this utility model, the auxiliary component includes a first transmission mechanism, a second transmission mechanism, and two mounting shafts, wherein,
[0017] Both mounting shafts are located inside the cylinder and are symmetrically distributed. The first transmission mechanism and the second transmission mechanism are located between the cylinder and the motor from right to left. One end of the first transmission mechanism and the second transmission mechanism are fixedly connected to the surface of the adjacent connecting shaft. The other ends of the two mounting shafts extend through the cylinder and are fixedly connected to the other ends of the first transmission mechanism and the second transmission mechanism, respectively.
[0018] In one embodiment of this utility model, a spiral conveying plate is fixedly connected to the surfaces of both mounting shafts, and the spiral directions of the two spiral conveying plates are opposite.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. By setting up a mixing assembly, the two connecting shafts can rotate in opposite directions under the combined action of the first bevel gear, the second bevel gear, and the connecting shaft. This drives the mixing rod to perform mixing operations in two directions, effectively improving the mixing effect and thus improving the mixing effect of concrete raw materials and the quality of concrete.
[0021] 2. By setting auxiliary components, the fluidity of raw materials can be improved during the mixing process, which can greatly improve the mixing effect of internal raw materials. In addition, the bottom spiral conveyor plate can assist the material inside the cylinder to move towards the discharge pipe during the material discharge process, which facilitates the discharge.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0030] The following description, in conjunction with the accompanying drawings, describes the cement pole sand and gravel mixing device of this utility model.
[0031] like Figure 1-4 As shown, the cement pole aggregate mixing device of this utility model embodiment includes a cylinder 1, an inlet pipe 101, an outlet pipe 102, and a mixing mechanism 2, wherein,
[0032] The feed pipe 101 is connected to the top surface of the cylinder 1, the discharge pipe 102 is connected to the bottom surface of the cylinder 1, and the mixing mechanism 2 is located inside the cylinder 1.
[0033] The mixing mechanism 2 includes a stirring component 21 and an auxiliary component 22. The stirring component 21 is disposed inside the cylinder 1, and the auxiliary component 22 is disposed on the surface of the stirring component 21.
[0034] Specifically, the raw materials of sand and gravel are added into the inside of the cylinder 1 through the feed pipe 101, and the mixing mechanism 2 is started to mix the raw materials inside. After the mixing is completed, the raw materials can be discharged through the discharge pipe 102.
[0035] In one embodiment of this utility model, such as Figure 1-4 As shown, in one embodiment of this utility model, the stirring assembly 21 includes two connecting shafts 2102, a protective shell 2104, a plurality of stirring rods 2107, and a motor 2101, wherein,
[0036] The protective shell 2104 is located at the center of the inside of the cylinder 1. Two connecting shafts 2102 are respectively located at both ends of the protective shell 2104. The motor 2101 is located on one side of the cylinder 1. The other end of one connecting shaft 2102 passes through the cylinder 1 and is fixedly connected to the output shaft of the motor 2101. The other end of the other connecting shaft 2102 is rotatably connected to the inner wall of the cylinder 1. Several stirring rods 2107 are fixedly connected to the surfaces of the two connecting shafts 2102 and are evenly distributed.
[0037] Specifically, starting the motor 2101 can drive the connecting shaft 2102 connected to it to rotate, which in turn drives the stirring rod 2107 to rotate, thereby realizing the mixing operation of the raw materials in the cylinder 1.
[0038] In one embodiment of this utility model, such as Figure 1-4As shown, a mounting rod 2106 is fixedly connected to the surface of the protective shell 2104, and the other end of the mounting rod 2106 is fixedly connected to the inner wall of the cylinder 1. A second bevel gear 2105 is rotatably connected to the inner wall of the protective shell 2104.
[0039] The opposite ends of the two connecting shafts 2102 pass through the protective shell 2104 and are fixedly connected to the first bevel gear 2103, which meshes with the second bevel gear 2105.
[0040] Specifically, during the rotation of the connecting shaft 2102 connected to the motor 2101, the first bevel gear 2103 connected to it can rotate synchronously, which in turn can drive the second bevel gear 2105 connected to it to rotate. In this process, the other first bevel gear 2103 can be driven to rotate in the opposite direction, thereby realizing that the two connecting shafts 2102 rotate in opposite directions during the stirring process, which further improves the mixing effect of the raw materials inside the cylinder 1.
[0041] In one embodiment of this utility model, such as Figure 1-3 As shown, the auxiliary component 22 includes a first transmission mechanism 2201, a second transmission mechanism 2202, and two mounting shafts 2203, wherein,
[0042] Both mounting shafts 2203 are located inside the cylinder 1 and are symmetrically distributed. The first transmission mechanism 2201 and the second transmission mechanism 2202 are located between the cylinder 1 and the motor 2101 from right to left. One end of the first transmission mechanism 2201 and the second transmission mechanism 2202 are fixedly connected to the surface of the adjacent connecting shaft 2102. The other end of the two mounting shafts 2203 passes through the cylinder 1 and is fixedly connected to the other end of the first transmission mechanism 2201 and the second transmission mechanism 2202, respectively.
[0043] Specifically, the first transmission mechanism 2201 and the second transmission mechanism 2202 are both relatively mature components in existing technology applications. They consist of two transmission wheels and a transmission belt. By driving the transmission wheel connected to it to rotate through the connecting shaft 2102, the other transmission wheel can be driven to rotate under the action of the transmission belt, which in turn can drive the mounting shaft 2203 to rotate synchronously.
[0044] In one embodiment of this utility model, such as Figure 1-3 As shown, spiral conveyor plates 2204 are fixedly connected to the surfaces of the two mounting shafts 2203, and the spiral directions of the two spiral conveyor plates 2204 are opposite.
[0045] During the rotation of the mounting shaft 2203, the screw conveyor plate 2204 can be driven to rotate synchronously. The screw directions of the two screw conveyor plates 2204 are opposite, which makes the conveying directions of the two screw conveyor plates 2204 opposite. Thus, two conveying flows with different directions can be formed on the raw materials inside the cylinder 1. While enhancing the fluidity of the internal raw materials, the mixing effect of the internal raw materials can be greatly improved in conjunction with the stirring rod 2107. In addition, the bottom screw conveyor plate 2204 can assist the material inside the cylinder 1 to move towards the discharge pipe 102 during the material discharge process, which facilitates the discharge.
[0046] Specifically, the overall workflow of this utility model is as follows:
[0047] The relevant personnel first transported raw materials such as cement and sand and gravel into the inside of cylinder 1 through the feed pipe 101 at the top of cylinder 1 to complete the raw material storage before mixing.
[0048] Then, the motor 2101 located on one side of the cylinder 1 is started. The output shaft of the motor 2101 drives the connecting shaft 2102 directly connected to it to start rotating. The connecting shaft 2102 driven by the motor 2101 drives the first bevel gear 2103 that passes through one end of the protective shell 2104 to rotate. The first bevel gear 2103 meshes with the second bevel gear 2105 inside the protective shell 2104, driving the first bevel gear 2103 on the other side and the connected shaft 2102 to rotate in the opposite direction. This causes the stirring rods 2107, which are evenly distributed on the surfaces of the two connecting shafts 2102, to rotate in opposite directions, thus performing bidirectional stirring and mixing of the raw materials in the cylinder 1.
[0049] While the connecting shaft 2102 rotates, its surface drives two symmetrically distributed mounting shafts 2203 to rotate synchronously through the first transmission mechanism 2201 and the second transmission mechanism 2202 respectively. Since the spiral conveying plates 2204 fixed on the surface of the mounting shaft 2203 have opposite spiral directions, two conveying flows with different directions are formed in the cylinder 1, which enhances the fluidity of the raw materials and further improves the mixing effect in conjunction with the stirring rod 2107.
[0050] After mixing, the raw materials are pushed towards the discharge pipe 102 at the bottom of the cylinder 1 with the assistance of the bottom spiral conveyor plate 2204, and finally discharged through the discharge pipe 102, thus completing the entire mixing process.
[0051] In summary, the cement rod sand and gravel mixing device of this utility model enhances the material flowability and mixing effect through dual-shaft reverse stirring and reverse screw conveying, while also assisting in material discharge, thereby improving the concrete mixing quality and discharge efficiency.
