Description

Technical Field

[0001] The invention relates to the technical field of measuring devices, and in particular to a volume measuring device and a measuring method for belt-transported ore. Background Art

[0002] The ore in the underground mine bin is evenly transported to the ore conveyor belt by the plate feeder of the ore loading station. The ore conveyor belt conveys the ore to the lifting bucket. After the camera measures the overall volume on the conveyor belt, the weight of the ore is obtained by combining the density. Some larger ores will interfere with the camera's measurement of the overall volume. In addition, larger ores do not meet the requirements of subsequent processing, so larger ores need to be transported and measured separately. When measuring the volume of some irregular objects, optical methods such as image recognition technology are often used for measurement. During the measurement process, two cameras are used to obtain the image of the object from different angles, and a three-dimensional model of the object is established through the image to calculate the volume. This measurement method is often used to measure the volume of ore.

[0003] Some metal mines, such as gold mines, install guard plates on both sides of the belt to prevent the ore from falling during belt transportation after mining. However, this operation causes the ore to be blocked by the guard plates during measurement, making it difficult for the camera to obtain a full view of the ore, resulting in inaccurate volume measurement.

[0012] A method for measuring the volume of belt-transported ore is also provided, comprising the following steps:

[0013] S1: When the ore is transported between the two guide blades by the belt, the servo push cylinder drives the lifting frame to move, and then drives the push bucket frame to move, so that the two concave buckets move towards each other to scoop up the ore between the two guide blades and lift it upwards;

[0014] S2: During the lifting process, the top ears will support the tooth plate, causing the guide plate near the second camera to flip and move away from between the second camera and the ore;

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the ore is transported between the two guide pieces by the belt, the end of the lifting frame will slide up on the guide rod, and the inclined frame will push the push wheel so that the push wheel can roll along the inclined surface of the inclined frame to drive the connecting ring to move backward, thereby driving the push bucket frame to move, so that the two bucket guide frames can slide synchronously in the guide shell, thereby driving the two concave buckets to move toward each other to shovel the ore between the two guide pieces. At this time, the end of the lifting frame is against the lower end of the guide shell, and then the lifting frame continues to move up to lift the guide shell. At this time, the main spring contracts and deforms to ensure that the guide shell moves up normally, so that the upward moving guide shell can drive the concave bucket and guide piece to move up synchronously to lift the ore and make it higher than the guard plates on both sides, so that the camera can obtain a full view of the ore, thereby ensuring the accuracy of volume measurement.

[0018] 2. When the ore is being lifted, the top ear will support the tooth plate to keep the tooth plate still. At the same time, the gear rolls on the tooth plate to drive the connecting shaft to rotate, thereby driving the guide plate near the second camera to flip and turn it away from between the second camera and the ore, so that the second camera will not be hindered by the guide plate when acquiring images, thereby ensuring the normal progress of the measurement operation. At the same time, when the two concave buckets move in opposite directions and reset, the guide plate will block the ore, so that the ore is fully separated from the inside of the concave bucket and falls on the belt to be transported away, so as to avoid the ore still staying in the concave bucket after the concave bucket is separated, affecting the measurement of the next piece of ore, thereby further ensuring the normal progress of the measurement operation.

The first camera 11 and the second camera 12 are used to obtain images of the ore from the top and the side of the ore, and a three-dimensional model of the ore is established through the images, and then the volume is calculated. Since the optical method of volume measurement through this image recognition technology is an existing design and has been widely used, it is not elaborated here and is not shown in the figure. An extension frame 4 is fixedly installed at the rear end edge of the measuring frame 1, and a guide rod 33 is elastically installed at the end of the extension frame 4.

Bucket guide frames 15 are slidably installed on both ends of the guide shell 13. The guide shell 13 and the bucket guide frame 15 guide the concave bucket 16. A connecting ring 37 is elastically installed at the rear end of the guide shell 13. A push bucket frame 7 is rotatably installed between the connecting ring 37 and the bucket guide frame 15. The connecting ring 37 can drive the push bucket frame 7 to move so that the two concave buckets 16 move toward each other to shovel the ore between the two guide pieces 17. A push wheel 6 is installed at the front end of the connecting ring 37. A lifting frame 36 is installed at the front end of the push wheel 6. The lower end of the lifting frame 36 is connected to the guide rod The lifting frame 36 is connected with the lifting frame 36 by sliding, and the rear end thereof is extended with an inclined frame 35. When the lifting frame 36 moves upward, it will drive the inclined frame 35 to move upward. At this time, the inclined frame 35 that moves upward will push the push wheel 6, so that the push wheel 6 can roll along the inclined surface of the inclined frame 35 to drive the connecting ring 37 to move backward. The ends of the two bucket guide frames 15 are fixedly installed with concave buckets 16. The opposite ends of the two concave buckets 16 are provided with guide pieces 17. On the one hand, the guide pieces 17 can use the inclined surfaces of their ends to guide the transported ore so that the ore moves between the two guide pieces 17. On the other hand, when the two concave buckets 16 move in the opposite direction and reset, the ore will be blocked so that the ore can be fully separated from the inside of the concave buckets 16 and It falls on the belt and is transported away. A flap piece is provided between one of the guide blades 17 and the guide shell 13, and the other guide blade 17 is fixed to the guide shell 13. One of the guide blades 17 is close to the second camera 12. The measuring frame 1 is placed next to the belt conveyor. At this time, the concave bucket 16 is attached to the belt. When the ore is transported between the two guide blades 17 by the belt, the servo push cylinder 3 works to scoop up and lift the ore. At the same time, the sensor can be used to sense the ore. When it is sensed that the ore is transported between the two guide blades 17, the controller is used to drive the servo push cylinder 3 to work. Because the above-mentioned control operation is a prior art and has been widely used, it is not elaborated here and is not shown in the figure.

A gear 27 is coaxially inlaid on the outer surface of the connecting shaft 19, and a tooth plate 25 is meshed on the side of the gear 27. The cooperation between the gear 27 and the tooth plate 25 can drive the connecting shaft 19 to rotate, so that the guide blade 17 near the No. 2 camera 12 is flipped and turned away from between the No. 2 camera 12 and the ore. The tooth plate 25 is elastically connected to the No. 2 fixing frame 18, and a top ear 5 is arranged above the tooth plate 25, and the top ear 5 is fixed to the extension frame 4. The top ear 5 can support the tooth plate 25 so that the upward movement height of the tooth plate 25 is positioned.

[0032] A connecting frame 20 is extended from the lower edge of the side of the second fixing frame 18, and a guide seat 21 is fixedly installed at the end of the connecting frame 20. The connecting frame 20 plays a role in fixing the guide seat 21. The front and rear end surfaces of the tooth plate 25 are provided with a slide groove 29. The end of the guide seat 21 is slidably installed inside the slide groove 29. The guide seat 21 and the slide groove 29 play a role in guiding the tooth plate 25. A limiting rod 23 is slidably installed inside the guide seat 21. The upper end of the limiting rod 23 is coaxially inlaid with a connecting cap 24, which is fixed to the tooth plate 25. The connecting cap 24 is fixed to the tooth plate 25. The cap 24 plays a role of connection and fixing. The outer side of the limiting rod 23 is wound with a return spring 22. The limiting rod 23 plays a role in preventing the return spring 22 from bending. One end of the return spring 22 is fixed to the lower end of the connecting cap 24, and the other end of the return spring 22 is fixed to the upper end of the guide seat 21. The return spring 22 plays a role in restoring the tooth plate 25 after the movement. The lower end of the limiting rod 23 is coaxially inlaid with a positioning cap 26. The positioning cap 26 is attached to the lower end of the guide seat 21, and the positioning cap 26 plays a role in positioning the reset position of the tooth plate 25.

[0033] A cylinder frame 2 is fixedly installed at the upper edge of the measuring frame 1, and a servo push cylinder 3 is fixedly installed at the end of the cylinder frame 2. The cylinder frame 2 plays a role in fixing the servo push cylinder 3. The output end of the servo push cylinder 3 is fixed to the lifting frame 36, and the servo push cylinder 3 plays a role in driving the lifting frame 36 to move. A through groove 28 is opened at the corner of the guide piece 17, and the front vertical edge of the concave bucket 16 is located on the inner side of the through groove 28. The through groove 28 can allow the two concave buckets 16 to smoothly pass through the guide piece 17 to close together. A No. 1 fixing frame 14 is fixedly installed at the front end of the guide shell 13 near the other side edge, and the end of the No. 1 fixing frame 14 is fixed to the other guide piece 17, and the No. 1 fixing frame 14 plays a role in fixing the other guide piece 17.

[0034] A fixed frame 8 is fixedly installed in the middle of the rear end of the guide shell 13, and the lifting frame 36 passes through the inside of the fixed frame 8. A moving rod 30 is slidably installed through the end of the fixed frame 8. The fixed frame 8 plays a role in carrying and guiding the moving rod 30. One end of the moving rod 30 is fixed to the connecting ring 37, and the moving rod 30 plays a role in guiding the connecting ring 37. The other end of the moving rod 30 is coaxially inlaid with a rod cap 31, and the rod cap 31 is attached to the rear end of the fixed frame 8. The rod cap 31 plays a role in positioning the reset position of the connecting ring 37. An auxiliary spring 10 is wound around the outside of the moving rod 30, and one end of the auxiliary spring 10 is fixed to the front end of the fixed frame 8, and the other end of the auxiliary spring 10 is fixed to the connecting ring 37. The auxiliary spring 10 can reset the moving connecting ring 37, thereby allowing the two closed concave buckets 16 to move in opposite directions to separate and reset.

The main spring 9 can press the guide shell 13 so that the inclined frame 35 pushes the push wheel 6 to drive the two concave buckets 16 to move toward each other, so that the guide shell 13 will not move up during the process of shoveling the ore between the two guide blades 17.

[0036] An upper convex cap 34 is coaxially embedded in the upper end of the guide rod 33, and the upper convex cap 34 is fitted to the upper end of the extension frame 4. The upper convex cap 34 serves to position the downward position of the guide shell 13. A lower convex cap 38 is coaxially embedded in the lower end of the guide rod 33, and the lower convex cap 38 serves to prevent the guide rod 33 and the lifting frame 36 from separating.

[0037] A method for measuring the volume of belt-transported ore is also provided, comprising the following steps:

[0038] S1: When the ore is transported between the two guide blades 17 by the belt, the servo push cylinder 3 works to drive the lifting frame 36 to move, and then drives the push bucket frame 7 to move, so that the two concave buckets 16 move toward each other, so as to scoop up the ore between the two guide blades 17 and lift it upward;

[0039] S2: During the lifting process, the top ear 5 will support the tooth plate 25, so that the guide plate 17 near the second camera 12 is flipped and turned away from between the second camera 12 and the ore;

[0040] S3: When the ore is lifted to the height of the second camera 12, the first camera 11 and the second camera 12 can acquire images of the ore from the top and side angles of the ore to measure the volume of the ore.

[0041] During measurement, when the ore is transported by the belt to between the two guide pieces 17, the servo push cylinder 3 will work, allowing the end of the lifting frame 36 to slide upward on the guide rod 33, and at the same time the inclined frame 35 pushes the push wheel 6, so that the push wheel 6 can roll along the inclined surface of the inclined frame 35, so as to drive the connecting ring 37 to move backward, thereby driving the bucket push frame 7 to move, so that the two bucket guide frames 15 can slide synchronously in the guide shell 13, thereby driving the two concave buckets 16 to move toward each other, so as to lift the two pieces of ore. The ore between the guide pieces 17 is shoveled up. During this process, the guide housing 13 is pressed by the main spring 9 to remain stationary, and the auxiliary spring 10 contracts and deforms to adapt to the movement of the connecting ring 37. When the ore is shoveled up, the end of the lifting frame 36 just presses against the lower end of the guide housing 13, and then the lifting frame 36 continues to move upward to lift the guide housing 13. At this time, the main spring 9 contracts and deforms to ensure that the guide housing 13 moves upward normally, so that the upwardly moving guide housing 13 drives the concave bucket 16 , the guide piece 17 moves up synchronously to lift the ore so that it is higher than the guard plates on both sides. When the ore is being lifted, the top ear 5 will support the tooth plate 25 to keep the tooth plate 25 still. At the same time, the gear 27 rolls on the tooth plate 25 to drive the connecting shaft 19 to rotate, thereby driving the guide piece 17 near the second camera 12 to flip over and turn it away from between the second camera 12 and the ore. Subsequently, the ore image is obtained from the top and side angles of the ore through the first camera 11 and the second camera 12 to measure the volume of the ore. After the measurement is completed, the above-mentioned components are reset, and when the two concave buckets 16 move in the opposite direction to reset, the guide piece 17 will block the ore, so that the ore is fully separated from the interior of the concave bucket 16 and falls on the belt to be transported away, so as to avoid the ore still staying in the concave bucket 16 after the concave bucket 16 is separated, thereby affecting the measurement of the next piece of ore.
