Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a concrete aggregate conveying device. Background Technology

[0002] Concrete aggregate conveying devices are key equipment in the concrete production process, primarily used to transport aggregates from storage silos to the mixing plant or other processing stations. In modern concrete production processes, the uniformity and efficiency of aggregate conveying directly affect the accuracy of the concrete mix proportions and the final product quality. Traditional conveying devices typically employ belt conveyors or vibrating feeders, but in practical applications, problems such as uneven aggregate distribution and accumulation / clogging often arise, making it difficult to meet the process requirements for high-quality concrete production. Therefore, developing a specialized device capable of achieving uniform aggregate distribution and efficient conveying is of great significance.

[0003] In existing technologies, concrete aggregate transport mainly employs a fixed belt conveyor with baffles. These devices typically use a motor-driven conveyor belt, with fixed guide plates achieving initial aggregate diversion. Some improved models add a vibrating screen above the conveyor belt, utilizing vibration to promote aggregate dispersion. For scraping, a common technique is to install a rigid scraper at the end of the conveyor belt, relying on mechanical pressure to remove residual aggregate. While these traditional structures can fulfill basic transport functions, they have significant limitations in motion adjustment and pressure control.

[0004] However, existing conveying devices generally suffer from the technical defect of easy spillage of aggregates during operation. Because traditional guiding structures lack dynamic adjustment capabilities, the guiding position cannot be adjusted in real time according to the feeding speed and flow rate when aggregates fall from the hopper onto the conveyor belt. This causes some aggregates to splash out of the conveyor belt area under impact. This spillage not only causes material waste and environmental pollution but also accumulates around the equipment, increasing the workload of cleaning and maintenance, and affecting the cleanliness of the production site and operational safety. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete aggregate conveying device, which aims to improve the problem that existing conveying devices often have the problem of aggregate spillage during operation, causing some aggregate to splash out of the conveyor belt under impact.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete aggregate conveying device, comprising a support platform, a fixing plate fixedly connected to the upper surface of the support platform, a conveyor belt disposed inside the support platform, and a guide component disposed on the upper surface of the conveyor belt;

[0007] The guiding assembly includes a guide plate, the lower surface of which is slidably connected to the upper surface of the conveyor belt. A connecting rod four is fixedly connected to the outer wall of the guide plate. A sliding plate is fixedly connected to one end of the connecting rod four. A guide rod is slidably connected inside the sliding plate. A fixing block is fixedly connected to the outer wall of a fixing plate one. An electric push rod is fixedly connected to the outer wall of the fixing plate one. A connecting rod one is fixedly connected to the output end of the electric push rod. A fixing sleeve is fixedly connected to the outer wall of the connecting rod one. A connecting rod two is fixedly connected to the outer wall of the fixing sleeve. A rotating shaft one is rotatably connected inside the connecting rod two. A connecting rod three is rotatably connected to the outer wall of the rotating shaft one. A rotating shaft two is rotatably connected inside the connecting rod three. A fixing plate two is fixedly connected to one end of the rotating shaft two.

[0008] Furthermore, a support frame is fixedly connected to the upper surface of the support platform, a fixed column is fixedly connected to the lower surface of the support frame, a fixed plate three is fixedly connected to the lower surface of the fixed column, and a scraping assembly is provided inside the fixed plate three.

[0009] Furthermore, the scraping assembly includes a scraper, the outer wall of which is slidably connected to the inner wall of the fixed plate, a fixed rod is fixedly connected to the upper surface of the scraper, a sliding rod is slidably connected to the inner wall of the fixed rod, and a spring is sleeved on the outer wall of the fixed rod.

[0010] Furthermore, one end of the guide rod is fixedly connected to an outer wall of the fixed plate, and an outer wall of the connecting rod is rotatably connected to the inner wall of the fixed block.

[0011] Furthermore, the outer wall of the fixed sleeve is rotatably connected to the inner wall of the fixed block, and the outer wall of the second fixed plate is fixedly connected to one side of the outer wall of the sliding plate.

[0012] Furthermore, a support rod is provided on one side of the support platform, and a hopper is fixedly connected to the outer wall of the support rod.

[0013] Furthermore, the fixing plate three is disposed below the support frame, and the scraper is disposed below the support frame.

[0014] Furthermore, one end of the spring is fixedly connected to the outer wall of the scraper, and the other end of the spring is fixedly connected to the inner wall of the fixed plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, an electric push rod drives a multi-link mechanism to enable the guide plate to reciprocate laterally on the surface of the conveyor belt, effectively guiding the uniform distribution of aggregate. The guide assembly adopts a sliding fit between the connecting rod and the sliding plate to ensure smooth movement of the guide plate and avoid aggregate accumulation or deviation. At the same time, the linkage design between the fixed sleeve and the rotating shaft enhances the flexibility of the mechanism, makes the aggregate diversion more accurate, significantly improves the transmission efficiency and the uniformity of material distribution, and reduces the need for manual intervention.

[0017] 2. In this utility model, the elastic pressure of the spring keeps the scraper in constant contact with the surface of the conveyor belt, and the scraping force is dynamically adjusted. This can effectively scrape off excessively thick aggregate layers and fill unevenly distributed areas. The cooperation between the fixed rod and the sliding rod ensures flexible contact of the scraper, preventing the aggregate from breaking due to rigid compression. This design not only optimizes the uniformity of the aggregate layer, but also extends the service life of the conveyor belt, while reducing material waste and improving the stability and economy of the overall transmission mechanism.

[0025] 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.

[0026] Reference Figures 1-4The present invention provides an embodiment of a concrete aggregate conveying device, including a support platform 1, which provides basic support and installation platform for the entire conveying device. A fixing plate 6 is fixedly connected to the upper surface of the support platform 1, which provides installation fixing points for the electric push rod 7 and the guide assembly. A conveyor belt 2 is provided inside the support platform 1, which serves as the main carrier for aggregate conveying and realizes continuous conveying of aggregate. A guide assembly is provided on the upper surface of the conveyor belt 2.

[0027] The guiding assembly includes a guide plate 5, which dynamically guides and diverts aggregates through lateral movement. The lower surface of the guide plate 5 is slidably connected to the upper surface of the conveyor belt 2. A connecting rod 18 is fixedly connected to the outer wall of the guide plate 5, transmitting the movement of the sliding plate 17 to the guide plate 5. One end of the connecting rod 18 is fixedly connected to the sliding plate 17, which slides on the guide rod 16, driving the connecting rod 18 to move. The guide rod 16 is slidably connected inside the sliding plate 17, providing linear motion guidance for the sliding plate 17. A fixing block 9 is fixedly connected to the outer wall of the fixing plate 6, providing a rotation fulcrum for the connecting rod 8 and the fixing sleeve 10. An electric push rod 7 is fixedly connected to the outer wall of the fixing plate 6, providing power to drive the movement of the guiding assembly. A connecting rod is fixedly connected to the output end of the electric push rod 7. Connecting rod 18 transmits the power of electric push rod 7 to fixed sleeve 10. Fixed sleeve 10 is fixedly connected to the outer wall of connecting rod 18, connecting and transmitting power to connecting rod 2 11. Connecting rod 2 11 is fixedly connected to the outer wall of fixed sleeve 10, transmitting power to rotating shaft 12. Rotating shaft 12 is rotatably connected inside connecting rod 2 11, realizing the power conversion between connecting rod 2 11 and connecting rod 3 13. Rotating shaft 12 is rotatably connected to the outer wall of connecting rod 3 13, converting rotational motion into linear motion, driving fixed plate 2 15 to move. Rotating shaft 2 14 is rotatably connected inside connecting rod 3 13, providing a rotation fulcrum for connecting rod 3 13. Fixed plate 2 15 is fixedly connected to one end of rotating shaft 2 14, transmitting the motion of connecting rod 3 13 to sliding plate 17.

[0028] Specifically, concrete aggregate first falls into the upper surface of conveyor belt 2 through hopper 4. After the electric push rod 7 is started, its output end pushes the connecting rod 8 to rotate around the inner wall of the fixed block 9, causing the fixed sleeve 10 to swing synchronously. The fixed sleeve 10 drives the rotating shaft 12 to rotate through the connecting rod 2 11, which in turn drives the connecting rod 3 13 to rotate around the rotating shaft 2 14. The movement of the connecting rod 3 13 pulls the fixed plate 2 15 to move. The fixed plate 2 15 drives the sliding plate 17 to slide linearly along the guide rod 16. The sliding plate 17 drives the guide plate 5 to make lateral reciprocating motion on the surface of the conveyor belt 2 through the connecting rod 4 18, realizing the dynamic guidance and diversion of the aggregate. This guiding mechanism can ensure that the aggregate is evenly distributed on the conveyor belt 2, effectively avoiding the accumulation or displacement of aggregate during the conveying process.

[0029] Reference Figure 1 and Figure 5A support frame 19 is fixedly connected to the upper surface of the support platform 1, providing a support structure for the scraping assembly. A fixed column 20 is fixedly connected to the lower surface of the support frame 19, connecting the support frame 19 and the fixed plate 21. The fixed plate 21 is fixedly connected to the lower surface of the fixed column 20, installing and fixing the scraping assembly. The scraping assembly, including a scraper 22, is installed inside the fixed plate 21. The scraping assembly scrapes and smooths the aggregate through flexible contact. The outer wall of the scraper 22 is slidably connected to the inner wall of the fixed plate 21. A fixed rod 23 is fixedly connected to the upper surface of the scraper 22, cooperating with a sliding rod 24 to realize the elastic movement of the scraper 22. A sliding rod 24 is slidably connected to the inner wall of the fixed rod 23, cooperating with the fixed rod 23 to limit the movement trajectory of the scraper 22. A spring 25 is fitted on the outer wall of the fixed rod 23 to provide elastic force so that the scraper 22 always fits against the surface of the conveyor belt 2. One end of the guide rod 16 is fixedly connected to the outer wall of the fixed plate 1 6. The outer wall of the connecting rod 1 8 is rotatably connected to the inner wall of the fixed block 9. The outer wall of the fixed sleeve 10 is rotatably connected to the inner wall of the fixed block 9. The outer wall of the fixed plate 2 15 is fixedly connected to one side of the outer wall of the sliding plate 17. A support rod 3 is provided on one side of the support platform 1. A hopper 4 is fixedly connected to the outer wall of the support rod 3 to store the concrete aggregate to be conveyed and to control the discharge of the aggregate. The fixed plate 3 21 is set below the support frame 19. The scraper 22 is set below the support frame 19. One end of the spring 25 is fixedly connected to the outer wall of the scraper 22, and the other end of the spring 25 is fixedly connected to the inner wall of the fixed plate 3 21.

[0030] Specifically, when the conveyor belt 2 transports aggregate to the area below the support frame 19, the scraper 22 inside the fixed plate 21 always maintains adaptive contact with the surface of the conveyor belt 2 under the elastic force of the spring 25. The scraper 22 performs secondary sorting of the aggregate on the conveyor belt 2 through flexible contact, on the one hand scraping down the excessively thick aggregate, and on the other hand filling the unevenly distributed areas, thereby ensuring that the aggregate layer thickness is uniform. The cooperation structure of the fixed rod 23 and the sliding rod 24, combined with the elastic extension and contraction characteristics of the spring 25, allows the scraper 22 to dynamically adjust the pressure according to the aggregate thickness, avoiding aggregate breakage due to rigid contact. After the adjustment of the scraping component, the aggregate forms a uniform and stable material layer on the conveyor belt 2, which not only improves the subsequent transmission efficiency, but also provides a good material foundation for the unloading process.

[0031] Working principle: When the concrete aggregate conveying device is needed, the concrete aggregate falls into the upper surface of the conveyor belt 2 through the hopper 4. After the electric push rod 7 is started, it pushes the connecting rod 1 8 to rotate along the inner wall of the fixed block 9, which drives the fixed sleeve 10 to swing synchronously. The fixed sleeve 10 drives the rotating shaft 12 to rotate through the connecting rod 2 11, so that the connecting rod 3 13 pulls the fixed plate 2 15 to move with the rotating shaft 2 14 as the fulcrum. This pushes the sliding plate 17 to slide along the guide rod 16. The sliding plate 17 drives the guide plate 5 to move laterally on the surface of the conveyor belt 2 through the connecting rod 4 18, so as to realize the dynamic guidance and diversion of the aggregate, ensuring that the aggregate is evenly distributed on the conveyor belt 2 and avoiding accumulation or displacement.

[0032] Furthermore, when the conveyor belt 2 transports aggregates below the support frame 19, the scraper 22 inside the fixed plate 21 adapts to the surface of the conveyor belt 2 under the elastic force of the spring 25. The scraper 22 performs secondary sorting of the aggregates on the conveyor belt 2 through flexible contact, scraping off excessively thick aggregates and filling unevenly distributed areas to ensure uniform aggregate layer thickness. The fixed rod 23 and the sliding rod 24, in conjunction with the elastic extension and contraction of the spring 25, enable the scraper 22 to dynamically adjust the pressure, avoiding excessive squeezing of the aggregates and causing breakage. Finally, after adjustment by the scraping assembly, the aggregates form a uniform and stable material layer on the conveyor belt 2, improving the efficiency of subsequent transmission and unloading.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
