Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device technology, and more specifically, to a hot aggregate elevator. Background Technology
[0002] Hot aggregate elevators are core equipment in asphalt concrete mixing plants used for vertically conveying heated aggregates. They typically consist of a frame, drive unit, conveyor belt, and buckets fixed on it. The buckets receive the high-temperature aggregates at the bottom of the elevator, and after being lifted to the top for unloading, the empty buckets descend along the return path to achieve continuous conveying.
[0003] However, during the long-term continuous operation of the elevator, a large amount of sticky material tends to adhere to the inner wall of the hopper. The cleaning method is usually to manually climb to the high position after the machine is stopped and knock it clean. This not only leads to production interruption and low efficiency, but also exposes the workers to the safety risks of falling from height and being burned by high temperature. At the same time, frequent forced shutdowns for maintenance also significantly increase the operating costs of the equipment, making it difficult to meet the requirements of continuous and efficient production of the mixing plant.
[0004] In view of this, we propose a hot aggregate lifting machine. Utility Model Content
[0005] 1. Technical problems to be solved The purpose of this utility model is to provide a hot aggregate elevator to solve the problem mentioned in the background art that the inner wall of the hopper of a traditional hot aggregate elevator is prone to sticky materials and is not easy to clean.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Please see Figure 1-7 This utility model provides a technical solution: A hot aggregate elevator includes an elevator body 1, which includes a frame 101 and a hopper 11 located at the bottom of the frame 101. A conveyor belt 12 and a motor 13 for driving the conveyor belt 12 are fixedly connected to the frame 101. Multiple hoppers 15 for feeding are fixedly connected to the conveyor belt 12, and each hopper 15 is equipped with a cleaning component 2. A discharge port 14 is opened at the top of the frame 101. An installation chamber 16 is fixedly connected to the vertical section of the frame 101 during the return trip of the hoppers 15, and a triggering component 3 is installed inside the installation chamber 16. The cleaning component 2 is also present. Used for cleaning the inside of hopper 15; trigger component 3 is used to trigger cleaning component 2. This setting, by placing the installation chamber 16 in a specific position, makes full use of the working conditions of hopper 15 being unloaded, descending stably, and having relatively spacious space below, providing a safe and stable installation platform for trigger component 3. This allows the device to accurately lock the timing and position of cleaning execution, avoiding possible interference or unreliability caused by cleaning in complex action areas such as loading or unloading. At the same time, by embedding trigger component 3 inside installation chamber 16, it can be effectively protected from the influence of harsh external working conditions.
[0022] Specifically, the cleaning component 2 includes two connecting rods 22 slidably connected to the hopper 15 and a pressure plate 21 fixedly connected to the two connecting rods 22. The connecting rods 22 pass through the hopper 15 and are elastically connected to the hopper 15 via springs 23. A cleaning plate 24 is slidably connected to the hopper 15, with the outer wall of the cleaning plate 24 overlapping the inner wall of the hopper 15. In its initial state, the cleaning plate 24 is located at the bottom of the hopper 15. The pressure plate 21 is used to cooperate with the trigger component 3 to make the cleaning plate 24 clean the inside of the hopper 15. This configuration, through the design of the connecting rods 22 that pass through the hopper 15 and are equipped with springs 23, enables the trigger component 3 to clean the inside of the hopper 15. Force is effectively transferred from the outside of the hopper 15 to the cleaning plate 24 inside. In addition, the spring 23 can be used to provide an automatic reset function after the cleaning plate 24 moves, ensuring that the cleaning plate 24 can quickly and reliably return to the initial position at the bottom of the hopper 15 after completing one scraping action, preparing for the next cleaning action and avoiding obstruction of subsequent aggregate loading. The initial position of the cleaning plate 24 is designed at the bottom of the hopper 15 to ensure that the scraping action can cover the starting position of the inner wall of the hopper 15. In other embodiments, the spring 23 can be replaced by a device such as an elastic telescopic rod to avoid the influence of sticky materials on the exposed spring 23.
[0023] Secondly, the trigger assembly 3 includes a first electric push rod 31 fixedly connected to the mounting chamber 16 and horizontally arranged, a movable frame 32 fixedly connected to the extended end of the first electric push rod 31, and a second electric push rod 33 fixedly connected to the frame 101. A trigger plate 34 that can move up and down to trigger the pressure plate 21 is slidably connected to the movable frame 32. In this arrangement, the two driving methods are completed by independent electric push rods, which enhances the controllability and adaptability of the system. The movable frame 32 serves as an intermediate carrier, realizing the connection and displacement transmission between the trigger plate 34 and the first push rod. The sliding connection provides guidance for the vertical movement of the trigger plate 34, ensuring that the vertical downward pressure can be transmitted to the pressure plate 21.
[0024] Furthermore, a first slider 37 with a T-shaped cross-section is fixedly connected to the trigger plate 34. A first groove 38 adapted to the size of the first slider 37 is provided on the movable frame 32. A collection bin 35 for collecting scraped raw materials is fixedly connected to the bottom of the movable frame 32. This arrangement ensures that the trigger plate 34 can slide smoothly up and down on the movable frame 32 while preventing it from detaching from the movable frame 32. This anti-detachment design is crucial in the case of frequent start-stop or impact conditions, as it can prevent the trigger plate 34 from accidentally falling and causing functional failure or safety hazards. The design of the collection bin 35 fixedly connected to the bottom of the movable frame 32 solves the problem of collecting residual materials after automatic cleaning. The sticky material scraped off from the inner wall of the hopper 15 by the cleaning plate 24 will fall naturally. The collection bin 35, located directly below the pressing position of the trigger plate 34, can effectively receive these scattered materials and prevent them from scattering and accumulating inside the elevator.
[0025] Furthermore, a movable block 36 is slidably connected to the trigger plate 34, and a second electric push rod 33 is fixedly connected to the frame 101, with the extended end of the second electric push rod 33 fixedly connected to the top of the movable block 36. This arrangement allows the trigger plate 34 to move freely in the vertical direction defined by the guide of the movable frame 32.
[0026] In addition, the bottom of the movable block 36 is fixedly connected to a second slider 39 with an inverted T-shaped cross section, and the trigger plate 34 is provided with a second slide groove 310 that matches the size of the second slider 39. This arrangement ensures that the movable block 36 can slide flexibly on the trigger plate 34 in a preset direction while restricting the movable block 36 from detaching from the trigger plate 34.
[0027] Specifically, the second electric push rod 33 pushes the movable block 36 and the trigger plate 34 downward at a speed greater than the conveying speed of the conveyor belt 12, so that the trigger plate 34 can press down the pressure plate 21 to clean the hopper 15. This setting allows the trigger plate 34 to catch up with and substantially press down the moving pressure plate 21 within a short dynamic contact time until the required downward stroke of the cleaning plate 24 is completed, ensuring the normal operation of the hopper 15 cleaning component 2.
[0028] Working principle: After the hopper 15 completes the aggregate lifting and discharges at the top outlet 14, the empty hopper enters the return vertical downward stage with the conveyor belt 12. When the hopper 15 moves to the corresponding position in the installation bin 16, the first horizontal electric push rod 31 fixed to the installation bin 16 first drives the movable frame 32 to move horizontally, so that the hopper 15 to be cleaned is located between the trigger plate 34 and the storage bin 35. Immediately afterwards, the second electric push rod 33 fixed to the frame 101 pushes the movable block 36 and the trigger plate 34 downward rapidly at a speed higher than that of the conveyor belt 12. The trigger plate 34 instantly... The pressure plate 21 on the hopper 15 is contacted and continuously pressed down, forcing the connecting rod 22 that passes through the hopper 15 to slide into the hopper against the resistance of the spring 23. Simultaneously, the cleaning plate 24 linked with the connecting rod 22 is driven to forcefully scrape the inner wall from the initial position at the bottom of the hopper 15. This scraping action peels off the hardened material adhering to the hopper wall. The residue falls into the collection bin 35 at the bottom of the movable frame 32 under gravity and is collected. After the scraping is completed, the first electric push rod 31 and the second electric push rod 33 both retract, causing the trigger component 3 to reset and trigger the cleaning component 2 of the next hopper 15.
