Description

Technical Field

[0001] This utility model relates to the field of electronic belt scale technology, specifically an electronic belt scale with a cleaning function. Background Technology

[0002] Electronic belt scales are key equipment installed on belt conveyors for the continuous measurement of bulk materials, and are widely used in industries such as mining, power, ports, and chemicals. Their core principle is to measure the weight of material per unit length of the belt using load cells, and then combine this with the belt speed measured by a speed sensor to calculate the instantaneous flow rate and cumulative weight.

[0003] In practical applications, belt-conveyed materials (such as coal, ore, and grain) often contain dust, moisture, or are sticky. These materials easily adhere to and accumulate in the weighing area, especially on the weighing rollers, scale frame structure, and sensor surfaces. Material and dust accumulation can lead to a series of problems: Measurement error: Adhering material becomes part of the "tare weight", causing zero drift and seriously affecting measurement accuracy.

[0004] Equipment damage: Hard, accumulated material may jam the idler rollers, preventing them from rotating, accelerating belt wear, and potentially damaging the weighing frame.

[0005] Existing cleaning methods mainly rely on regular manual cleaning, which is inefficient and poses safety hazards. A few devices are equipped with independent sweepers, but their installation location and cleaning effect are often unsatisfactory, failing to effectively and promptly clean the bottom area of ​​electronic belt scales.

[0006] Therefore, this utility model provides an electronic belt scale with a cleaning function to solve the above problems. Utility Model Content

[0017] 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.

[0018] like Figures 1-5 As shown, this utility model provides an electronic belt scale with a cleaning function, including a belt scale body 1. The bottom of the belt scale body 1 is provided with a first cleaning mechanism 2 and a second cleaning mechanism 3. The first cleaning mechanism 2 is connected to the second cleaning mechanism 3 through a connecting plate 4. The first cleaning mechanism 2 includes a frame 201. Multiple rotating holes are equidistantly spaced on the top of the frame 201. The frame 201 is rotatably connected to multiple rotating rods 202 through these holes. A cleaning brush 203 is fixedly connected to the top of each rotating rod 202. The bottom end of the middle rotating rod 202 is connected to the output end of a motor 204. The motor 204 is fixedly connected to the bottom of the inner wall of the frame 201. By setting up the first cleaning mechanism 2 and the second cleaning mechanism 3, the belt scale achieves automated cleaning of the belt working surface through a combination of sweeping and blowing, eliminating the need for manual intervention and significantly improving production efficiency. Simultaneously, it effectively prevents material adhesion and accumulation in the weighing area, fundamentally eliminating zero-point drift caused by material accumulation. This ensures the long-term measurement accuracy and stability of the electronic belt scale, reduces wear on the weighing rollers and belt caused by hard materials, lowers the equipment failure rate, and extends the overall service life of the equipment.

[0019] A first gear 5 is fixedly connected to the outer wall of the rotating rod 202 located in the middle, and a second gear 6 is fixedly connected to the outer wall of the rotating rods 202 located on both sides. The outer walls of the first gear 5 and the second gear 6 mesh with each other. By setting the first gear 5 and the second gear 6, multiple rotating rods 202 can be driven to rotate synchronously, thereby driving multiple cleaning brushes 203 to rotate. Multiple cleaning brushes 203 can clean multiple positions of the belt scale body, ensuring comprehensive cleaning.

[0020] Multiple bearing seats 8 are fixedly connected at equal intervals to the top of the inner wall of the frame 201. Bearings 7 are installed inside the bearing seats 8. The bearing seats 8 are rotatably connected to the rotating rod 202 through the bearings 7. By setting the bearing seats 8 and bearings 7, they can play an auxiliary support role during the rotation of the rotating rod 202, ensuring the stability of the rotation of the rotating rod 202. At the same time, they can also reduce the friction generated when the rotating rod 202 rotates, ensuring the efficiency of the rotation of the rotating rod 202 and avoiding the situation of rotation jamming.

[0021] The second cleaning mechanism 3 includes a ventilation box 301. One side of the ventilation box 301 is fixedly connected to the corresponding side of the frame 201 via a connecting plate 4. The bottom of the ventilation box 301 has multiple mounting slots. The ventilation box 301 is detachably installed with multiple fans 302 via the multiple mounting slots. By setting up the second cleaning mechanism 3, cleaning is carried out by blowing. The debris cleaned by the cleaning brush 203 can be further blown outward to ensure the cleaning effect of the belt scale.

[0022] Multiple air outlet nozzles 303 are equidistantly arranged on the top of the ventilation box 301. The air outlet nozzles 303 are connected to the interior of the ventilation box 301 through flexible hoses. The air outlet nozzles 303 are floating nozzles. By setting the floating nozzles, the angle of the air outlet nozzles 303 can be adjusted to achieve a multi-angle blowing effect, ensure the comprehensiveness of the blowing, and avoid the occurrence of cleaning dead corners.

[0023] The two ends of the belt scale body 1 are fixedly connected to the same base 9. Multiple electric telescopic rods 10 are fixedly connected to the bottom of the inner wall of the base 9. The top of the electric telescopic rod 10 is connected to the bottom of the frame 201. By setting the electric telescopic rod 10, the height of the first cleaning mechanism 2 and the second cleaning mechanism 3 can be adjusted so that the cleaning brush 203 in the first cleaning mechanism 2 can fit against the bottom of the belt of the belt scale body 1, thus ensuring the cleaning effect of the cleaning brush 203.

[0024] Working principle: In use, the electric telescopic rod 10 is activated, which moves the frame 201 upward. The frame 201 then moves the cleaning brush 203 upward, bringing it into contact with the bottom of the belt of the belt scale body. Simultaneously, as the frame 201 moves upward, it drives the second cleaning mechanism 3 upward via the connecting plate 4. Then, the fan 302 and motor 204 are activated. The motor 204 drives the central rotating rod 202 to rotate, which in turn drives the first gear 5 to rotate. The first gear 5 drives the two second gears 6 to rotate, thus causing the three rotating rods 202 to rotate synchronously. The rotation of the rotating rods 202 drives the cleaning brush 203 to rotate, allowing the high-speed rotating cleaning brush 203 to clean the bottom of the belt of the belt scale body. At the same time, the airflow generated by the fan 302 is transmitted to the air outlet nozzle 303 through the ventilation box 301. The high-speed airflow ejected by the air outlet nozzle 303 works in conjunction with the cleaning brush 203 to perform a secondary cleaning of debris.

[0025] 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.
