Description

Technical Field

[0001] This utility model relates to the field of concrete additive technology, and in particular to a vibratory feeding device for concrete additives. Background Technology

[0002] Concrete additives are substances that can significantly improve the physical and chemical properties of concrete, increase its strength and durability, save cement usage, and reduce the size of structures, thereby achieving energy conservation and environmental and social benefits. A concrete additive vibrating feeder is a device used to automatically and continuously transport and distribute concrete additives during the concrete preparation process. This device uses a vibration mechanism to uniformly feed powdered or granular concrete additives into the mixing system to ensure their reasonable distribution in the concrete.

[0003] However, this device has some problems: First, due to the electrostatic adsorption phenomenon generated by the material during vibration, blockage often occurs at the discharge port, which prevents the concrete additive from falling smoothly and evenly; second, the mixing process between cement and concrete additive is not sufficient, resulting in uneven mixing and affecting the quality and performance of the final concrete. These problems will significantly reduce production efficiency and affect the consistency and strength of the finished concrete. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0022] Reference Figure 1-4 A vibratory feeding device for concrete additives includes a processing box 1. The top of the processing box 1 has two inlets 2 for introducing different raw material streams. The inner wall of each inlet 2 is connected to a feeding cylinder 3. This feeding design allows cement and concrete additives to simultaneously enter the processing box 1 through the inlets 2. The outer walls of the two feeding cylinders 3 are connected to elastic mechanisms. A motor 4 is fixedly connected to the outer wall of the processing box 1. This motor 4 is one of the core driving components of the device, providing the necessary power to support the entire feeding and mixing system. The output end of the motor 4 is fixedly connected to a rotating... Shaft 5, located inside the processing chamber 1, has multiple sets of stirring blades fixedly connected to its outer wall. This allows the material to be mixed more deeply and comprehensively, achieving a more thorough and efficient process of homogenizing the quality. The rotating shaft 5 passes through the side wall of the processing chamber 1 and is connected to a rotating shaft 7 via a transmission mechanism. Multiple mixing blades 8 are fixedly connected to the outer wall of the rotating shaft 7 inside the processing chamber 1. The stirring blades are used to initially mix the input material flow, dispersing it evenly within the chamber. The ends of the rotating shaft 7 pass through the two side walls of the processing chamber 1 and are fixedly connected to a turntable 9. The turntable 9 is connected to a linkage mechanism.

[0023] The elastic mechanism includes a push plate 14 fixedly connected to the outer wall of the feed cylinder 3. A telescopic rod 15 is fixedly connected to the bottom of the push plate 14. The bottom of the telescopic rod 15 is fixedly connected to the top of the processing box 1. A telescopic spring 16 is sleeved on the outer wall of the telescopic rod 15 to ensure stability and elastic recovery capability. The two ends of the telescopic spring 16 are fixedly connected to the bottom of the push plate 14 and the top of the processing box 1, respectively. This design not only provides a sufficient range of elastic deformation, but also allows the material to quickly return to its original state after the external force is removed, thus ensuring the continuity and stability of the vibratory feeding.

[0024] The transmission mechanism includes a first transmission wheel fixedly connected to the outer wall of the rotating shaft 5, and a second transmission wheel fixedly connected to the outer wall of the rotating shaft 7. The first and second transmission wheels are connected by a transmission belt 6 to ensure that they can move synchronously. This connection method can effectively transmit the power from the power source to each moving part, so that the whole device works in coordination.

[0025] The linkage mechanism includes a fixed plate 13, on which a sliding groove is provided. A sliding plate 10 is slidably connected to the inner wall of the sliding groove. The sliding groove is used to guide and support the sliding plate 10 to move inside it, so that the sliding plate 10 can reciprocate up and down on the fixed plate 13. The bottom of the sliding plate 10 is connected to the rotating shaft 7 through a tie rod 11. An impact head 12 is fixedly connected to the bottom of the sliding plate 10. The impact head 12 is used to make necessary physical contact with the material during the working process, thereby ensuring that the additives and cement can be fed quickly.

[0026] Both the outer wall of the turntable 9 and the outer wall of the sliding plate 10 are fixedly connected to a linkage shaft. The turntable 9 and the sliding plate 10 will change position as the feeding action is performed. In order to ensure that this change can be effectively transmitted and controlled, linkage ports are opened at both ends of the pull rod 11. The inner wall of the two linkage ports is rotatably sleeved with the outer wall of the linkage shaft. The linkage ports and the linkage shaft form a rotatable sleeve relationship, ensuring that the pull rod 11 can rotate freely within a certain range without affecting the overall working efficiency of the equipment.

[0027] The feed cylinder 3 is located inside the processing box 1 and is fixedly connected to the outer wall of the outer wall of the feed cylinder 3. The clamping plate 17 is an auxiliary fixing structure. It is connected to the outer wall of the feed cylinder 3 through a strong mechanical connection, thereby effectively preventing the feed cylinder 3 from loosening and shifting during vibration.

[0028] The specific working principle of this utility model is as follows:

[0029] In its initial state, when this device is in use, cement and concrete additives first enter the device through the two feed ports 2 set at the top. As the feeding process proceeds, the motor 4 is started, and its output end drives the rotating shaft 5 to rotate synchronously. In addition, the rotating shaft 5 is also connected to another rotating shaft 7 through a transmission mechanism, which allows the rotating shaft 7 to rotate in the corresponding direction. The mixing blades 8 rotate accordingly, thus creating a preliminary stirring effect inside the device. At the same time, the multiple sets of mixing blades distributed on the rotating shaft 5 inside the processing box 1 also rotate together, making the mixing more comprehensive and thorough.

[0030] At the same time, the turntable 9 rotates, and the sliding plate 10 moves up and down through the pull rod 11, so that the impact head 12 impacts the push plate 14 and knocks the feed cylinder 3, so that the material in the feed cylinder 3 can be discharged quickly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
