Description

Technical Field

[0001] This utility model relates to the field of ore testing technology, specifically to an ore hardness testing device. Background Technology

[0002] The hardness of the mined ore not only reflects the geological changes in the mining area along the mining direction, but also involves the adjustment of the crusher's workload during the initial crushing process. Therefore, during the mining process, technicians need to regularly check the hardness of the ore and obtain the approximate range of the ore hardness by scratching the ore with a standard hardness block.

[0003] For example, Chinese utility model patent CN202323625328.6 describes a ore hardness testing device. By placing the ore on the upper surface of a moving mechanism and then activating the moving mechanism, the ore can be moved between the fixed components on both sides, reducing the burden on the workers and making it more convenient. However, the loading of the moving mechanism still requires the workers to move the ore onto the upper surface of the moving mechanism on the workbench, increasing the workers' burden.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a device for testing the hardness of ores, which has the following advantages:

[0017] This ore hardness testing device works by pushing the ore to be tested into the feeding hopper, then activating the hydraulic rod, which pushes the feeding hopper to rotate. As the rotation angle of the feeding hopper gradually increases, one end of the hydraulic rod slides through the first slider to the other end of the first chute, making the feeding hopper rotate perpendicular to the worktable. This allows the contents of the feeding hopper to be poured out and rolled onto the transmission belt for transportation, increasing the convenience of ore feeding and transportation and reducing the burden on the staff.

[0028] The hardness of the mined ore not only reflects the geological changes in the mining area along the mining direction, but also involves the adjustment of the crusher's workload during the initial crushing process. Therefore, during the mining process, technicians need to regularly check the hardness of the ore and obtain the approximate range of the ore hardness by scratching the ore with a standard hardness block.

[0029] In related technologies, the feeding work of the moving mechanism still requires workers to move the ore onto the upper surface of the moving mechanism on the workbench, which increases the workload of the workers.

[0030] To address some of the problems in the related technologies, this application provides an ore hardness testing device. When ore needs to be fed and transported, the ore whose hardness needs to be tested is simply pushed into the feeding hopper 22. Then, the hydraulic rod 23 is activated, which pushes the feeding hopper 22 to rotate. As the angle of rotation of the feeding hopper 22 gradually increases, one end of the hydraulic rod 23 slides through the first slider 24 to the other end of the first slide groove 241, so that the feeding hopper 22 rotates perpendicular to the worktable 11, thereby causing the feeding hopper 22 to empty its contents and roll onto the transmission belt 21 for transport.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figures 1-3 This application provides an ore hardness testing device, including a device body 1. The device body 1 includes: an electric lifting rod 12 disposed on the top of a workbench 11; a hardness testing device 13 disposed between the electric lifting rods 12; a clamping assembly 14 symmetrically disposed on the top of the workbench 11; a feeding and conveying assembly 2 disposed on the workbench 11, the feeding and conveying assembly 2 including: a transmission belt 21 passing through the top of the workbench 11; a feeding hopper 22 disposed on one side of the workbench 11 and rotatably connected to the workbench 11; a hydraulic rod 23 passing through one side of the workbench 11 and located on one side of the feeding hopper 22; a first slider 24 disposed at one end of the hydraulic rod 23; a first groove 241 cooperating with the first slider 24 disposed on the outer side wall of the transmission belt 21; and a buffer assembly 25 disposed on the inner side of the feeding hopper 22.

[0033] In operation, the operator pushes the ore to be tested into the feeding hopper 22, then activates the hydraulic rod 23. The hydraulic rod 23 pushes the feeding hopper 22 to rotate. As the rotation angle of the feeding hopper 22 gradually increases, one end of the hydraulic rod 23 slides through the first slider 24 to the other end of the first chute 241, causing the feeding hopper 22 to rotate perpendicular to the worktable 11. This allows the feeding hopper 22 to empty its contents. As the ore rolls and falls from the feeding hopper 22, it first rolls onto the buffer assembly 25 for cushioning, and then exits from the buffer assembly 25. The ore is rolled onto the transmission belt 21 for transport, which increases the convenience of ore loading and transportation and reduces the burden on the staff. After the transmission belt 21 moves the ore to the predetermined position, the ore is clamped and fixed by the clamping component 14. Then, the hardness testing device 13 is lowered by the electric lifting rod 12, so that the blade on the hardness testing device 13 contacts the surface of the ore and cuts it. Finally, the hardness of the ore is judged by observing whether scratches are made, and the hardness of the ore is obtained according to the location of the scratches and the raw materials of the manufacturing of the curved blade.

[0034] Specifically, the hardness testing device 13 has the following structure: a motor, a fixed cutter head, and a transmission shaft. The first motor is located on the front end face of the rear connecting frame. One end of the transmission shaft is connected to the rear end face of the front connecting frame, and the other end of the transmission shaft is coaxially connected to the front end face of the fixed cutter head. The fixed cutter head and the transmission shaft are rotatably connected. The output shaft of the first motor is coaxially connected to the rear end face of the fixed cutter head. The fixed cutter head has an arc-shaped blade clamped inside. The motor drives the fixed cutter head to rotate, and the transmission shaft improves the stability of the fixed cutter head. The rotating fixed cutter head can also drive the arc-shaped blade to rotate, thereby cutting the surface of the ore. This section is not shown in the attached drawings of the specification.

[0035] Specifically, the electric lifting pole 12 controls multiple drive motors simultaneously through a controller to ensure that they rotate at the same speed, thereby achieving synchronous lifting.

[0036] Specifically, the hydraulic rods 23 use proportional valves or flow controllers to ensure that the two hydraulic rods 23 receive the same flow, thereby maintaining synchronous extension and retraction.

[0037] In some embodiments, the buffer assembly 25 includes: a baffle 251 disposed inside the hopper 22; and a damper 252 disposed between the baffle 251 and the inner wall of the hopper 22. When the angle of the hopper 22 is subsequently increased, the ore in the hopper will roll to one side and fall onto the baffle 251. The damper 252 will buffer the impact force of the ore falling onto the baffle 251. As the angle of the hopper 22 continues to increase, the ore on the baffle 251 will roll onto the transmission belt 21, preventing the ore in the hopper from rolling directly onto the transmission belt 21 and damaging it.

[0038] In some embodiments, the baffle 251 is provided with second sliders 26 on both sides, and the inner sidewall of the feeding hopper 22 is provided with a second sliding groove 261 that cooperates with the second sliders 26 to support the baffle 251 and increase the stability of the baffle 251 in the movement of the feeding hopper 22.

[0039] In some embodiments, a shock-absorbing pad 253 is provided on the outer side of the baffle 251 to reduce the damage caused by ore rolling down and impacting the baffle 251.

[0040] In some embodiments, a limiting plate 27 is provided on the top of the workbench 11 and is located on one side of the electric lifting rod 12, so that the ore rolling off the baffle 251 will roll accurately onto the transmission belt 21, preventing the ore from rolling off the workbench 11.

[0041] In some embodiments, the transmission belt 21 includes: a motor 211 disposed on the outside of the workbench 11; a drive shaft 212 disposed at the output end of the motor 211 and passing through the workbench 11; a driven shaft 213 disposed on one side of the drive shaft 212; and a conveyor belt 214 sleeved on the outside of the drive shaft 212 and the driven shaft 213. The motor 211 drives the drive shaft 212 to rotate, and the rotating drive shaft 212 pushes the outer conveyor belt 214 and the driven shaft 213 to rotate, and the rotating conveyor belt 214 transports the ore.

[0042] In some embodiments, the clamping assembly 14 includes: a support plate 141 symmetrical to the top of the workbench 11; an electric push rod 142 passing through the support plate 141; and a limiting clamping piece 143 disposed at one end of the electric push rod 142. When the ore is transported to a predetermined position, the electric push rod 142 pushes the two sets of limiting clamping pieces 143 to move relative to each other, thereby clamping the ore.

[0043] In some embodiments, a feed plate 15 is provided on the other side of the workbench 11. The tested ore is transported to one end by the conveyor belt 21 and rolls off the workbench 11 via the feed plate 15.
