[0003] A precious metal smelting sampler is a device specially used for collecting samples in the precious metal smelting process.

When the sliding ring 208 moves longitudinally, the first connecting column 206 is driven to move longitudinally through the second gear ring 207. When the first connecting column 206 moves longitudinally, it drives the guide ball 205 to slide inside the first guide groove 202, the second guide groove 203, and the third guide groove 204. When the guide ball 205 is inside the first guide groove 202, the flow groove 212 on the sampling dish 114 and the flow groove 212 on the sliding dish 211 are interlaced.

In this step, the flow groove 212 on the sampling plate 114 and the flow groove 212 on the slide plate 211 are mutually connected, so that the smelting sample can flow out or flow into the inner side of the sampling plate 114 better. The flow groove 212 on the sampling plate 114 and the flow groove 212 on the slide plate 211 are interlaced, so that the sample flowing into the inner side of the sampling plate 114 is stored in the inner side of the sampling plate 114. Through the overall matching design, the device can automatically open the sample taking and placing according to the longitudinal position of the sampling plate 114, so that the detection efficiency is significantly improved, and the process of manual participation is reduced, thereby improving production safety. ;

[0029] like Figure 1-2 , Figure 6As shown, a second servo motor 301 is fixedly connected to one side of the third support frame 106; a first fixed column 302 is fixedly connected to the output end of the second servo motor 301; a third gear 303 is fixedly connected to the outer side of the first fixed column 302; a fourth gear 305 is fixedly connected to the end of the second threaded rod 105 away from the threaded block 107; a transmission connection chain 304 is connected between the third gear 303 and the fourth gear 305; when working, the second servo motor 301 is started, and the first fixed column 302 is driven to rotate through the output end of the second servo motor 301, and the third gear 303 is driven to rotate through the rotation of the first fixed column 302, and then the third gear 303 is driven to rotate through the third The gear 303 transmission chain 304 causes the multiple sets of fourth gears 305 to rotate, and then the fourth gears 305 drive the second threaded rod 105 to rotate, so that the threaded connection with the second threaded rod 105 is made through the threaded block 107, so that the threaded block 107 can move laterally on the inner side of the third support frame 106, and then the base 101 is driven to move laterally through the threaded block 107. In this step, the threaded block 107 moves laterally on the inner side of the third support frame 106, so that the staff can adjust the position of the support tube 108, so that the equipment can take samples at different smelting positions, thereby improving the representativeness of the sampling, optimizing the smelting process, improving product quality and improving production safety.

At the same time, after sampling, the support cylinder 108 can be turned to the top of the detection equipment, and then the sampling dish 114 can be lowered, so that the device can automatically place the sample on the detection equipment. In this step, the equipment can perform sampling at different smelting angles, thereby improving the sampling representativeness, optimizing the smelting process, improving product quality and improving production safety. At the same time, by automatically placing the sample above the detection equipment, the detection efficiency is improved and the process of manual participation is reduced, thereby improving production safety.

[0032] like Figure 8 As shown, the lower end of the base 101 is fixedly connected to a cylinder 601; the telescopic end of the cylinder 601 is fixedly connected to a third connecting column 602; a fourth support frame 603 is fixed to the end of the third connecting column 602 away from the cylinder 601; the four end corners of the fourth support frame 603 are rotatably connected to wheels 604; when working, the cylinder 601 is started, and the third connecting column 602 is driven to move longitudinally through the telescopic end of the cylinder 601, thereby driving the fourth support frame 603 to move longitudinally, and thereby driving the wheels 604 to move longitudinally. In this step, by extending the wheels 604 out of the outside of the base 101, the equipment can be moved, thereby improving the flexibility of the equipment. At the same time, by retracting the wheels 604 into the inside of the base 101, the wheels 604 are no longer in contact with the ground, thereby making the equipment more stably placed, thereby improving production safety.

[0033] like Figure 1 , Figure 8 As shown, the four end corners of the base 101 are fixedly connected with a fixing frame 701; the inner side of the fixing frame 701 is slidably connected with a second fixing column 702; during operation, when the equipment is moved to a specified position, the staff can fix the second fixing column 702 in the ground by passing the fixing frame 701.

[0034] Working principle: the staff sets a timed start for the first servo motor 109. When the first servo motor 109 is started, the first servo motor 109 drives the first gear 110 to rotate by forward rotation. When the first gear 110 rotates, it drives the first gear ring 111 to rotate. When the first gear ring 111 rotates, it drives the second gear 112 to rotate. When the second gear 112 rotates, it drives the third threaded rod 113 to rotate, so that the two third threaded rods 113 move longitudinally synchronously. When the third threaded rod 113 moves longitudinally, the slider 115 drives the sampling dish 114 to move longitudinally, so that the sampling dish 114 is immersed in the metal smelting, and then the first servo motor 109 is reversed to take out the sampling dish 114. In this step, the first servo motor is set to The start, forward and reverse rotation of the setting makes it possible for the sampling dish 114 to take samples at a set time, making the operation more convenient and reducing the process of manual participation in the metal smelting process, thereby improving production safety. During operation, when the sampling dish 114 moves longitudinally, the sliding ring 208 is driven to move longitudinally through the connecting block 209. When the sliding ring 208 moves longitudinally, the first connecting column 206 is driven to move longitudinally through the second gear ring 207. When the first connecting column 206 moves longitudinally, it drives the guide ball 205 to slide inside the first guide groove 202, the second guide groove 203 and the third guide groove 204. When the guide ball 205 is inside the first guide groove 202, the flow groove 212 on the sampling dish 114 and the flow groove 212 on the sliding dish 211 are connected. The second toothed ring 207 is staggered with each other. When the second toothed ring 207 moves from the outside of the second guide groove 203, the second toothed ring 207 is driven to rotate at the same time when it moves longitudinally through the structural design of the second guide groove 203 and the guide ball 205. When the second toothed ring 207 rotates, it drives the third toothed ring 210 to rotate. When the third toothed ring 210 rotates, it drives the slide plate 211 to rotate. When the guide ball 205 slides into the inner side of the third guide groove 204, the flow groove 212 on the slide plate 211 and the flow groove 212 of the sampling plate 114 are interconnected. In this step, the flow groove 212 on the sampling plate 114 and the flow groove 212 on the slide plate 211 are interconnected, so that the smelting sample can flow out of or into the inner side of the sampling plate 114 better, and the flow groove on the sampling plate 114 is passed through. 212 and the flow slot 212 on the slide plate 211 are interlaced with each other, so that the sample flowing into the inner side of the sampling plate 114 is stored in the inner side of the sampling plate 114. Through the overall matching design, the device can automatically open for taking samples and placing samples according to the longitudinal position of the sampling plate 114, so that the detection efficiency is significantly improved, and the process of manual participation is reduced, thereby improving production safety. When working, the second servo motor 301 is started, and the first fixed column 302 is driven to rotate through the output end of the second servo motor 301, and the third gear 303 is driven to rotate through the rotation of the first fixed column 302, and then the third gear 303 drives the chain 304 to rotate the multiple fourth gears 305, and then the fourth gear 305 drives the second threaded rod 105 to rotate.Thus, the threaded block 107 is threadedly connected with the second threaded rod 105, so that the threaded block 107 can move laterally on the inner side of the third support frame 106, and then the threaded block 107 drives the base 101 to move laterally. In this step, the threaded block 107 moves laterally on the inner side of the third support frame 106, so that the staff can adjust the position of the support tube 108, so that the equipment can take samples at different smelting positions, thereby improving the sampling representativeness, optimizing the smelting process, improving product quality and improving production safety. When working, the third servo motor 401 is started, thereby driving the first threaded rod 103 to rotate, and the threaded portion between the first threaded rod 103 and the second support frame 104 is threaded. The second support frame 104 is connected so that the second support frame 104 can move longitudinally inside the first support frame 102, thereby allowing the support tube 108 to move longitudinally. In this step, the second support frame 104 moves laterally inside the first threaded rod 103, thereby allowing the staff to adjust the position of the support tube 108, so that the equipment can take samples at different smelting depths, thereby improving the sampling representativeness, optimizing the smelting process, improving product quality and improving production safety. When working, the fourth servo motor 501 is started, and the second connecting column 502 is driven to rotate through the output end of the fourth servo motor 501, and then the first support frame 102 is driven to rotate through the second connecting column 502, so that the equipment can Sampling at various angles can be performed in the smelting. At the same time, after sampling, the support tube 108 can be turned to the top of the detection device, and then the sampling dish 114 can be lowered, so that the device can automatically place the sample on the detection device. In this step, the device can perform sampling at different smelting angles, thereby improving the representativeness of sampling, optimizing the smelting process, improving product quality, and improving production safety. At the same time, by automatically placing the sample on the top of the detection device, the detection efficiency is improved while reducing the process of manual participation, thereby improving production safety. When working, start the cylinder 601, and the telescopic end of the cylinder 601 drives the third connecting column 602 to move longitudinally, thereby driving the fourth support The support frame 603 moves longitudinally, thereby driving the wheel 604 to move longitudinally. In this step, the wheel 604 is extended out of the outside of the base 101, so that the equipment can be moved, thereby improving the flexibility of the equipment. At the same time, the wheel 604 is retracted into the inside of the base 101, so that the wheel 604 is no longer in contact with the ground, so that the equipment is placed more stably, thereby improving production safety. During work, when the equipment moves to the designated position, the staff can fix the second fixing column 702 in the ground by passing the fixing frame 701.
