Description

Technical Field

[0001] This utility model relates to the field of concrete production cleaning technology, and in particular to a concrete conveyor belt cleaning device. Background Technology

[0002] As a core facility in modern construction engineering, concrete mixing plants rely on a continuous and efficient material conveying system for their production process. Because large quantities of raw materials such as sand and gravel need to be lifted to the top of the mixing unit, belt conveyors are commonly used for continuous and automated vertical transport. This process places high demands on the mechanical properties of the conveyor belt and the power system. The belt must possess sufficient tensile strength and wear resistance, and a high-power drive motor is required to ensure that power is transmitted smoothly and reliably to the drive drum, ultimately driving the conveyor belt to operate stably. During this process, cement slurry, fine aggregate, and other residual materials inevitably adhere to the belt surface. If these are not cleaned thoroughly and promptly, it will not only affect the normal operation of the equipment but also exacerbate belt wear, misalignment, and even damage. Therefore, an effective and reliable cleaning device has become a crucial element in ensuring the stable operation of the entire mixing plant.

[0003] A utility model disclosure (CN216037035U) discloses a head cleaning device for a conveyor belt in a concrete mixing plant. Specifically, it includes a baffle, a cleaning shaft, and a base. A recycling bin is fixedly installed on the top of the base. A discharge plate is fixedly installed on the upper end of the recycling bin between the limiting rods. A scraper is fixedly installed on the top of the discharge plate. A support frame is fixedly installed on the top of the base on one side of the limiting rods. The cleaning shaft is movably installed between the support frames. A drive shaft is fixedly installed through the support frame at the front end of the cleaning shaft. A baffle is fixedly installed on the upper end of the recycling bin on the other side of the limiting rod. A guide plate is fixedly installed on the other side of the baffle. A motor is fixedly installed on one side of the bin. A transmission belt is provided between the motor and the drive shaft. This utility model, through a series of structural features, enables the device to effectively clean the head of the conveyor belt in a concrete mixing plant during use, extending the service life of the conveyor belt.

[0004] The aforementioned patent also has the following problems: since the cleaning shaft is fixed in position, it is difficult to adapt to different belt installation heights or compensate for tolerances caused by manufacturing and installation processes in actual use. At the same time, it cannot effectively deal with the vibration phenomenon caused by load changes in the belt during operation. This rigid connection method is prone to unstable contact pressure between the cleaning shaft and the belt surface: when the pressure is too high, it will significantly accelerate the wear of the cleaning mechanism and the belt surface, shortening the service life of both; when the pressure is too low, it cannot effectively remove the adhering material, resulting in substandard cleaning effect. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete conveyor belt cleaning device to solve the problems mentioned in the background art, where the existing cleaning shaft is fixed in position, making it difficult to adapt to different belt installation heights or compensate for tolerances caused by manufacturing and installation processes in actual use. At the same time, it cannot effectively deal with the vibration phenomenon caused by belt load changes during operation. This rigid connection method easily leads to unstable contact pressure between the cleaning shaft and the belt surface: when the pressure is too high, it will significantly accelerate the wear of the cleaning mechanism and the belt surface, shortening the service life of both; when the pressure is too low, it cannot effectively remove the adhering materials, resulting in substandard cleaning effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This concrete conveyor belt cleaning device, through an adjustable structure, uses a first electric push rod to drive a linkage mechanism, which in turn drives a rotating shaft and a rotating gear to rotate synchronously. This, in turn, precisely drives the rotating shaft and rotating frame to achieve linked lifting and lowering through gear meshing transmission. This enables precise and synchronous adjustment of the cleaning brush height, effectively adapting to changes in conveyor belt height under different installation conditions and working conditions. It ensures that the cleaning brush and belt surface always maintain optimal contact pressure and cleaning angle, significantly improving the stability of the cleaning effect, the adaptability of the equipment, and the overall operating efficiency.

[0016] 2. This concrete conveyor belt cleaning device, through its cleaning structure, uses a second electric push rod to drive the first and second moving frames to move synchronously in opposite directions, causing the first and second rotating blocks to precisely clamp both ends of the cleaning brush, forming a stable double-sided support structure. Then, the motor drives the second rotating block to rotate the cleaning brush at a uniform speed, achieving precise control of the contact pressure between the cleaning brush and the surface of the conveyor belt and continuous and uniform rotational cleaning, effectively improving cleaning efficiency and consistency. At the same time, it avoids brush body vibration or uneven wear caused by unilateral driving or unstable clamping, significantly enhancing the stability of the cleaning process and the service life of the equipment.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a concrete conveyor belt cleaning device, including a base frame 1, an adjustment structure 2 on the base frame 1, and a cleaning structure 3 on the adjustment structure 2;

[0024] The adjustment structure 2 includes a fixed frame 201, a rotating shaft 202 movably mounted on the fixed frame 201, a rotating gear 203 mounted on the rotating shaft 202, a rotating shaft 204 movably mounted on the fixed frame 201, a rotating gear 205 mounted on the rotating shaft 204 and meshing with the rotating gear 203, a rotating bracket 206 mounted on the rotating shaft 204, a support frame 207 mounted on the fixed frame 201, a connecting rod 208 mounted on the rotating shaft 202, and a first electric push rod 209 movably mounted on the support frame 207. The electric push rod 209 is movably connected to the connecting rod 208. When the height of the cleaning brush 308 needs to be adjusted according to the height of the conveyor belt, the first electric push rod 209 is driven. The first electric push rod 209 can drive the connecting rod 208 to rotate. The connecting rod 208 can drive the rotating shaft 202 to rotate on the fixed frame 201. The rotating shaft 202 can drive the rotating gear 203 to rotate. Under the action of the rotating gear 203, the rotating gear 205 drives the rotating shaft 204 to rotate on the fixed frame 201. The rotating shaft 204 can drive the rotating frame 206 to rotate to adjust the height of the cleaning brush 308 to match the conveyor belt.

[0025] Furthermore, the base frame 1 is equipped with support legs, which are reliably connected to the main body of the base frame 1 through a threaded structure. This not only effectively compensates for installation deviations caused by uneven ground, but also significantly improves the vibration resistance and overall stability of the equipment under high-speed operation or load fluctuation conditions by lowering the overall center of gravity and increasing the contact area. The rotating shaft 202 is adapted to the fixed frame 201 and forms a support pair with the fixed frame 201 through a high-precision rolling bearing. The bearing seat adopts a double-sided sealing structure and applies appropriate preload, ensuring that the rotating shaft 202 can maintain extremely high rotational accuracy and dynamic stability when subjected to radial and axial combined loads, thereby providing a smooth and reliable power transmission foundation for the transmission system.

[0026] Furthermore, the rotating shaft 204 is adapted to the fixed frame 201, and the paired high-precision angular contact bearing and the fixed frame 201 form a rigid support structure. The bearing seat adopts double-sided positioning and applies preload, which effectively controls the radial runout and axial movement of the shaft system during high-speed rotation, thereby ensuring the motion accuracy and dynamic stability of the transmission system under variable load conditions. The fixed frame 201 is provided with reinforcing ribs, which significantly improves the bending stiffness and natural frequency of the mounting base under complex alternating loads, providing a stable and reliable working foundation for the transmission components.

[0027] Furthermore, the cleaning structure 3 includes a connecting plate 301, which is mounted on the rotating frame 206. A guide rail 302 is provided on the connecting plate 301, and a slider 303 is movably mounted on the guide rail 302. A first movable frame 304 is provided on the slider 303, and a first rotating block 305 is movably mounted on the first movable frame 304. A second movable frame 306 is provided on the slider 303, and a second rotating block 307 is movably mounted on the second movable frame 306. Cleaning brushes 308 are provided on the first rotating block 305 and the second rotating block 307. A motor 309 is provided on the second movable frame 306, and the driving end of the motor 309 is connected to the second rotating block 307. The first movable frame 304... A second electric push rod 310 is provided, and the driving end of the second electric push rod 310 is connected to the second movable frame 306. When the conveyor belt needs to be cleaned, the cleaning brush 308 is placed between the first rotating block 305 and the second rotating block 307. The second electric push rod 310 is driven, which can drive the first movable frame 304 and the second movable frame 306 to move closer to each other. The first movable frame 304 and the second movable frame 306 can drive the first rotating block 305 and the second rotating block 307 to move closer to both ends of the cleaning brush 308. The motor 309 is driven, which can drive the second rotating block 307 to rotate. The cleaning brush 308 rotates under the action of the first rotating block 305 and the second rotating block 307 to clean the conveyor belt.

[0028] Furthermore, the guide rail 302 is adapted to the slider 303, and adopts a high-precision linear guide pair structure. Its contact surface is hardened and an appropriate preload is applied, which effectively eliminates movement gaps and improves rigidity, thereby ensuring that the slider 303 always maintains a low-friction, creep-free, and stable running state during reciprocating motion. The first rotating block 305 is adapted to the first moving frame 304, and forms a slewing support unit with the first moving frame 304 through a precision bearing. The bearing is pre-tightened and adopts a long-term lubrication design, which can simultaneously withstand radial and axial loads, thereby ensuring that the rotating block has sufficient dynamic stability while achieving precise angle adjustment.

[0029] Furthermore, the second rotating block 307 is adapted to the second moving frame 306, and a high-rigidity crossed roller bearing is used to achieve a precise fit with the second moving frame 306. This bearing structure has excellent anti-overturning moment capability and rotational accuracy, and the axial and radial clearance is effectively eliminated through pre-tightening adjustment, thereby ensuring that the second rotating block 307 can maintain rotational stability when subjected to eccentric loads. The motor 309 is fixed to the second moving frame 306 by bolts. This connection method not only ensures the strict coaxiality requirements between the output shaft of the motor 309 and the transmission system, but also realizes the quick disassembly and maintenance of the motor 309 through modular interface design, which greatly improves the convenience of equipment maintenance.

[0030] Furthermore, the second electric push rod 310 is fixed to the first moving frame 304 by bolts. This standardized interface design not only ensures that the push rod has sufficient support stiffness and positioning accuracy during operation, but also provides significant convenience for subsequent maintenance or component replacement, effectively shortening equipment downtime. The connecting plate 301 is provided with reinforcing ribs, which significantly improves the bending and torsional stiffness and vibration stability of the connection node under complex alternating loads, providing reliable structural support for the entire motion mechanism.

[0031] Working principle: The entire device is placed below the conveyor belt. The cleaning brush 308 is positioned between the first rotating block 305 and the second rotating block 307. The second electric push rod 310 is driven, which in turn moves the first movable frame 304 and the second movable frame 306 closer together. The first movable frame 304 and the second movable frame 306 can then move the first rotating block 305 and the second rotating block 307 closer to both ends of the cleaning brush 308. When the height of the cleaning brush 308 needs to be adjusted according to the height of the conveyor belt, the first electric push rod 209 is driven. The first electric push rod 209 can then move... The moving link 208 rotates, which drives the rotating shaft 202 to rotate on the fixed frame 201. The rotating shaft 202 drives the rotating gear 203 to rotate. Under the action of the rotating gear 203, the rotating gear 205 drives the rotating shaft 204 to rotate on the fixed frame 201. The rotating shaft 204 drives the rotating frame 206 to rotate to adjust the height of the cleaning brush 308 to match the conveyor belt. The drive motor 309 drives the second rotating block 307 to rotate. Under the action of the first rotating block 305 and the second rotating block 307, the cleaning brush 308 rotates to clean the conveyor belt.
