Description

Technical Field

[0001] This utility model belongs to the field of magnetite grade measuring devices, and specifically relates to a press-type magnetite grade measuring device. Background Technology

[0002] During mining operations, it is necessary to test the grade of the ore. Traditional ore grade testing requires sampling from the mine and bringing the samples back for testing, which is inconvenient. For some ores, such as magnetite, preliminary on-site testing can be performed. During testing, a tool is used to attach a magnet to the ore to be tested, and the grade of the magnetite is determined by the force required to pull the magnet away. However, in current technology, the preliminary testing tool uses an external support to hold the magnet and the magnet block together, and then pulls on the extension connected to the magnet in the middle. The grade is determined by the force required to pull the magnet block away. This requires two hands to operate and pull, which is inconvenient in narrow mine shafts or testing areas. At the same time, the internal and external extension structure is also prone to increasing the failure rate, such as interference with the testing connection line or entanglement and pulling. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To overcome the limitations of existing technologies, the initial testing tool uses external support to make the magnet and the magnet block fit together, and then pulls the extension connected to the magnet in the middle. The grade is judged by the force of pulling the magnet block away. It requires two hands to operate and pull, which is inconvenient in narrow mines or detection areas. At the same time, the internal and external extension structure is also prone to increasing the failure rate, such as interference with the detection connection line or entanglement and pulling.

[0005] (II) Technical Solution

[0006] This utility model is achieved through the following technical solution: This utility model proposes a press-type magnetite grade measuring device, the structure of which includes a support rod, a controller and a probe. The support rod is fixed to the bottom of the probe, and the controller is used for recording and controlling the probe detection.

[0007] The probe includes a fixed body, an elastic ring, a diaphragm, a magnet, a tension sensor, a first assembly plate, a pressing body, an assembly ring, an air hole, a piston head, a spring, a push rod, a second assembly plate, and connecting wires. The pressing body is a ring-shaped body, and the fixed body is sleeved around one end of the pressing body. A piston head and a push rod are embedded in the bottom of the pressing body near the fixed body. The piston head is fixed to the push rod away from the fixed body. The piston head is interference-fitted with the pressing body. The push rod is locked to the second assembly plate near the fixed body. A slot is left between the side of the second assembly plate and the inside of the fixed body. The magnet, the tension sensor, and the first assembly plate are located at the inner ring end of the pressing body. The fixed body side is fixedly connected to the second assembly plate via a tension sensor. A magnet is fixed to the side of the first assembly plate away from the tension sensor. The magnet is flush with the side of the pressing body away from the fixed body. A diaphragm is fitted onto the side of the pressing body away from the fixed body. An assembly ring is fitted onto the end face of the pressing body. An elastic ring connects the assembly ring to the fixed body. A spring is also fitted between the assembly ring and the fixed body. A sealed space is formed between the fixed body, the elastic ring, the pressing body, and the assembly ring. One end of the vent is connected to the sealed space, and the other end is connected to the piston head away from the push rod. The connecting wire is used for the electrical connection between the tension sensor and the controller.

[0008] Furthermore, the probe also includes a rod mounting connector, which is fixed to the side of the fixing body away from the pressing body, and is used to support the fixed assembly of the rod.

[0009] Furthermore, a first sealing ring is embedded and wrapped around the side end face of the pressing machine body adjacent to the side of the fixed machine body. The first sealing ring is used to seal the side end face of the pressing machine body and the fixed machine body.

[0010] Furthermore, a second sealing ring is embedded on the side end of the piston head, which is used to seal the junction between the side end face of the piston head and the press body.

[0011] Furthermore, the elastic ring, the first sealing ring, and the second sealing ring are all made of rubber.

[0012] Furthermore, the side end face of the diaphragm is inlaid with more than one elastic band, and the side end face of the press body is provided with an assembly groove adjacent to the diaphragm side, and the side end face of the diaphragm is bound to the assembly groove by the elastic band.

[0013] Furthermore, the support rod is a telescopic rod, and a locking bolt is threaded onto the side end face of the support rod. The locking bolt is used to lock the support rod during telescopic adjustment.

[0014] Furthermore, a protective cover is provided at the bottom of the support rod, which is used for the airtight protection of the bottom of the support rod.

[0015] Furthermore, one end of the connecting wire is connected to the tension sensor, and the other end of the connecting wire passes through the second assembly plate, the inside of the support rod, and the protective cover in sequence to be electrically connected to the controller.

[0016] Furthermore, the two ends of the connecting line are fixedly connected to the second assembly plate and the protective cover, respectively, and the middle part of the connecting line is coiled into a spring-like spiral structure.

[0017] (III) Beneficial Effects

[0018] One of the above technical solutions has the following advantages or beneficial effects:

[0019] The press-type probe, consisting of a fixed body and a pressing body, operates by pressing the probe against the detection point via a support rod. The support rod then presses the probe, compressing the elastic ring and spring within the pressing body, which then enters the fixed body. During this process, the enclosed space formed by the elastic ring, spring, fixed body, and pressing body is also compressed, allowing air to enter the piston head through an air vent. This causes the piston head to push the second assembly plate towards the support rod via a push rod. The second assembly plate, through a tension sensor, moves the first assembly plate and magnet towards the support rod, causing the magnet to detach from the ore being tested. The tension sensor then reads the force at the moment of detachment, thus determining the ore grade. This press-type measurement is simple and convenient, without interference or entanglement, and is suitable for operation in confined spaces. Measurement can be performed wherever the probe can be inserted. Furthermore, the design of the probe being flush with the pressing body when not in use ensures that the detection value is not affected by gravity or other factors, resulting in high accuracy.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0028] Example 1:

[0029] This utility model provides a press-type magnetite grade measuring device: its structure includes a support rod 1, a controller 2 and a probe 3, the support rod 1 is fixed to the bottom of the probe 3, and the controller 2 is used for recording and controlling the detection of the probe 3;

[0030] The probe 3 includes a fixed body 301, an elastic ring 302, a diaphragm 303, a magnet 304, a tension sensor 305, a first assembly plate 306, a pressing body 307, an assembly ring 308, an air hole 309, a piston head 310, a spring 311, a push rod 312, a second assembly plate 313, and a connecting wire 314. The pressing body 307 is a ring, and the fixed body 301 covers and sleeves one end of the pressing body 307. The side of the pressing body 307 adjacent to the fixed body 301... A piston head 310 and a push rod 312 are embedded in the bottom. The piston head 310 is fixed to the side of the push rod 312 away from the fixed body 301. The piston head 310 is interference-fitted with the pressing body 307. The side of the push rod 312 adjacent to the fixed body 301 is locked to the second mounting plate 313. The side of the second mounting plate 313 has a slot inside the fixed body 301. The magnet 304, the tension sensor 305, and the first mounting plate 306 are located at the inner ring end of the pressing body 307. The mounting plate 306 is fixedly connected to the second mounting plate 313 via a tension sensor 305 on the side adjacent to the fixed body 301. A magnet 304 is fixed to the side of the first mounting plate 306 away from the tension sensor 305. The side of the magnet 304 away from the fixed body 301 is flush with the side of the pressing body 307 away from the fixed body 301. The diaphragm 303 is fitted onto the side of the pressing body 307 away from the fixed body 301. An assembly ring 308 is fixedly fitted onto the end face of the pressing body 307. An elastic ring 302 connects the mounting ring 308 to the fixed body 301. A spring 311 is also installed between the mounting ring 308 and the fixed body 301. A sealed space is formed between the fixed body 301, the elastic ring 302, the pressing body 307, and the mounting ring 308. One end of the air hole 309 is connected to the sealed space, and the other end of the air hole 309 is connected to the piston head 310 away from the push rod 312. The connecting wire 314 is used for the electrical connection between the tension sensor 305 and the controller 2.

[0031] The probe 3 also includes a rod mounting connector 315, which is fixed to the side of the fixing body 301 away from the pressing body 307. The rod mounting connector 315 is used to support the fixed assembly of the rod 1.

[0032] The pressing body 307 has a first sealing ring 30701 embedded on its side end face adjacent to the fixed body 301. The first sealing ring 30701 is used to seal the pressing body 307 side end face with the fixed body 301.

[0033] The piston head 310 has a second sealing ring 31001 embedded on its side end, which is used to seal the connection between the side end face of the piston head 310 and the press body 307.

[0034] The elastic ring 302, the first sealing ring 30701, and the second sealing ring 31001 are all made of rubber.

[0035] The support rod 1 is a telescopic rod, and a locking bolt 101 is threadedly connected to the side end face of the support rod 1. The locking bolt 101 is used to lock the support rod 1 during telescopic adjustment.

[0036] The support rod 1 is provided with a protective cover 102 at its bottom, which is used for sealing and protecting the bottom of the support rod 1.

[0037] One end of the connecting line 314 is connected to the tension sensor 305, and the other end of the connecting line 314 passes through the second assembly plate 313, the inside of the support rod 1 and the protective cover 102 in sequence and is electrically connected to the controller 2.

[0038] The two ends of the connecting line 314 are fixedly connected to the second assembly plate 313 and the protective cover 102, respectively, and the middle part of the connecting line 314 is coiled into a spring-like spiral structure.

[0039] In use, after the probe 3 is pressed against the detection point by the support rod 1, the probe 3 is pressed further down, causing the pressing body 307 to compress the elastic ring 302 and spring 311 and enter the fixed body 301. During this process, the sealed space formed by the elastic ring 302, spring 311, fixed body 301 and pressing body 307 is also compressed, allowing air in the sealed space to enter the piston head 310 through the air hole 309. This causes the piston head 310 to press the second assembly plate 313 towards the support rod 1 via the push rod 312, causing the second assembly plate 313 to move through the tension sensor. The device 305 moves the first assembly plate 306 and the magnet 304 toward the support rod 1, thereby causing the magnet 304 to detach from the ore being tested. At this time, the tension sensor 305 will obtain the value of the force when the magnet 304 detaches, thereby determining the ore grade and realizing press-type measurement. The operation is simple and convenient, without interference or entanglement, and is easy to operate in a small space. Measurement can be performed as long as the probe 3 can be inserted. At the same time, the design of the probe 3 having its adsorption side flush with the pressing body 307 when not measuring ensures that the detection value is not affected by gravity or other factors during detection, resulting in high accuracy.

[0040] Meanwhile, when the probe 3 is in use, the magnet 304 is isolated from the outside world by the diaphragm 303, reducing the adsorption of debris on the magnet 304, ensuring cleanliness, and facilitating long-term use.

[0041] Example 2:

[0042] Compared to Embodiment 1, in this embodiment, the diaphragm 303 has one or more elastic bands 30301 embedded on its side end face. The side end face of the presser body 307 adjacent to the diaphragm 303 is provided with an assembly groove 30702. The side end face of the diaphragm 303 is bound to the assembly groove 30702 by the elastic bands 30301. During use, if too much debris is adsorbed on the diaphragm 303, or if the diaphragm 303 is damaged, or if the internal parts of the presser body 307 need to be repaired, the diaphragm 303 can be quickly removed by pulling the elastic bands 30301 out of the assembly groove 30702, which is convenient for maintenance and replacement.
