[0002] Slag powder is primarily used for blending into cement and adding it to commercial concrete. While its utilization varies, it can be broadly classified into three forms: admixture, additive, and primary admixture. Its primary effects are improving the early strength of cement and concrete, as well as certain concrete properties, such as workability, early strength, and heat of hydration. Slag powder is typically sampled and inspected when stored in tanks. This sampling is typically performed on a stratified basis, using a hollow tube inserted into the slag powder pile and then withdrawn for testing.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 In this embodiment, a device for detecting the moisture content of slag powder includes a workbench 1, on the surface of which a conveying mechanism and a drying box 6 covering a rear section of the conveying mechanism are installed, as well as a suction cup loading device 4 and an injection device 5 fixedly located above and in the front of the conveying mechanism, and a material guide assembly 7 distributed on the left side of the conveying mechanism. A plurality of weighing pans 10 are placed on the conveying mechanism, and a plurality of lifting assemblies 8 and a plurality of blocking assemblies 9 installed on the inner side of the conveying mechanism and located below the weighing pan 10. A cross-shaped notch is provided on the top of the weighing pan 10, and a carrying box 11 is placed inside the cross-shaped notch.

[0020] In the above structure, the conveying mechanism can drive the weighing plate to move to the bottom of the suction cup loading device, the injection device and the material guide assembly in sequence. At the same time, the jacking assembly and the blocking assembly cooperate to limit the weighing plate, so that the weighing plate stays at the specified position, completing the loading of the carrier box and injecting the product into the carrier box. The weighing plate will display the initial weight, and the weighing plate will be driven by the conveying mechanism to pass through the drying box to complete the drying operation. After the drying is completed, the weighing plate will display the weight after drying, and the dried product will be discharged through the material guide assembly, and then the carrier box will be transferred to cleaning, and the weighing plate will continue to run, so that automated continuous production can be achieved, and the products can be packed into the carrier box at the same time. In conjunction with the weighing plate, the efficiency of detection is improved, thereby reducing the time cost of production.

[0021] Among them, in order to achieve stable circular conveying of the weighing plate, the conveying mechanism includes two roller conveyor platforms 2 fixed on the workbench 1, the drying box 6 covers the rear roller conveyor platform 2, and two belt conveyor platforms 3 are fixed to the top of the workbench 1 to connect the head and tail ends of the two roller conveyor platforms 2. The head and tail ends of the roller conveyor platforms 2 are both provided with docking conveyor platforms 12, and the docking conveyor platforms 12 are installed on the jacking components 8 located at the head and tail ends of the roller conveyor platforms 2. First, the combination of the roller conveyor platform and the docking conveyor platform can make the weighing plate circulate and transport. When the product is conveyed to the tail end of the front roller conveyor platform or the head end of the back roller conveyor platform, the jacking assembly will drive the corresponding docking conveyor platform to lift up and align with the corresponding belt conveyor platform, so that the weighing plate can be smoothly transported to the belt conveyor platform. Then, the jacking assembly at the head end of the front roller conveyor platform or the tail end of the back roller conveyor platform will drive the corresponding docking conveyor platform to lift up and align with the corresponding belt conveyor platform. When the weighing plate is completely located on the docking conveyor platform, the jacking assembly retreats, so that the push plate can be completely placed on the roller conveyor platform for transportation, which can avoid the displacement of the weighing plate during transportation.

[0022] like Figure 3 In the direction shown, in order to keep the weighing plate at the specified position, the blocking assembly 9 includes three mounting plates 901 fixed to the inner side of the first roller conveyor platform 2, a pushing cylinder 902 is installed at the bottom of the mounting plate 901, a pushing block 903 is fixed to the pushing end of the pushing cylinder 902, a blocking wheel 905 is hinged on the inner side of the pushing block 903, and a buffer column 904 located below the right end of the blocking wheel 905 is fixed to the top of the pushing block 903. When the roller conveyor platform transports the push plate, the pushing block is lifted up in advance by the pushing cylinder, thereby driving the blocking wheel to lift up, so that the weighing plate can be blocked by the blocking wheel. During the blocking process, the lower right end of the blocking wheel will move downward, so the buffer block plays a buffering role. In summary, the weighing plate can be blocked under the suction cup loading device to complete the loading of the carrier box, wherein a waiting area is formed between the suction cup loading device and the injection device 5. At the same time, when the weighing plate continues to be transported, the weighing plate is blocked under the injection device to prepare for injecting the product.

[0023] In addition, the front of the push block 903 is fixed with two blocking posts 907 and a limit plate 906 torsionally hinged between the two blocking posts 907. The top of the limit plate 906 is protruding and formed with a slope. The torsion of the limit plate 906 is less than the torsion of the blocking wheel 905. The front of the blocking wheel 905 is fixed with a protrusion that fits the slope of the limit plate 906. When the weighing plate is transported, when the blocking wheel is blocked, it will first be buffered by the buffer post, and at the same time, the limit plate will be squeezed by the protrusion. Then, the limit plate is limited by the blocking post, so that the movement of the blocking wheel can be limited, while improving the buffering effect.

[0024] like Figure 3 and 4 In the direction shown, the lifting assembly 8 includes five support plates 801 fixed on the inner side of the front roller conveyor platform 2, and support plates 801 fixed at the head and tail of the inner side of the rear roller conveyor platform 2. The total number of support plates 801 is seven, and the seven support plates 801 are arranged in a concave shape. An upward push cylinder 803 and four guide columns 802 are installed on the support plate 801. The upward push end of the upward push cylinder 803 is fixed with an upward push plate 804 connected to the four guide columns 802. The four docking conveyor platforms 12 are respectively installed on two groups of four longitudinally distributed upper push plates 804, and the three transversely distributed upper push plates 804 are fixed with limiting columns 805 that can extend to the bottom of the weighing plate 10. When the weighing pan is blocked by the blocking component, the push-up cylinder drives the push-up plate to lift up, so that the weighing pan can be lifted up by the push-up plate, so that the weighing pan is separated from the roller of the roller conveyor platform. At the same time, the limit column is inserted into the bottom of the weighing pan to prevent the weighing pan from deviating when loading or injecting samples, thereby playing a limiting role. Then the push-up cylinders located at the head and tail sections operate according to actual conditions, driving the docking conveyor platform to dock with the belt conveyor platform and completing the docking at the same time. After the docking is completed, the push-up cylinder returns to its position, thereby ensuring that the weighing pan falls completely on the roller conveyor platform for transportation.

[0025] like Figure 2 To achieve automatic unloading, the material guide assembly 7 includes a vertical plate 701 fixed to the workbench 1 and located above the left belt conveyor 3. A belt-type moving device 702 is installed on the front of the vertical plate 701. A lower cylinder 703, which is slidably connected to the vertical plate 701, is fixed to the belt end of the belt-type moving device 702. A concave plate 704 is fixed to the lower top of the lower cylinder 703, and a flipping clamp is installed on the concave plate 704. The belt conveyor and the lower cylinder can drive the flipping clamp to be located above the belt conveyor and above the unloading area, approaching the carrier box to clamp it, and at the same time, flipping it to pour out the dried product inside for collection. The carrier box is then moved to a cleaning area for storage and waiting for cleaning. When the carrier box is removed, the value on the weighing plate is reset to zero.

[0026] The flipping gripper comprises a rotating cylinder 705 mounted on the back of a concave plate 704, and a rotating post 706 rotatably connected to the rotating end of the rotating cylinder 705. A clamping cylinder 707 is mounted on the outer side of the rotating post 706, and an L-shaped clamping plate 708 is fixed to the clamping end of the clamping cylinder 707. In the initial state, the L-shaped clamping plate faces downward. When the L-shaped clamping plate clamps the carrier and transfers it to the unloading station, the rotating cylinder drives the clamping cylinder to rotate via the rotating post, and the clamping cylinder can also rotate back and forth to pour the products in the carrier into the collection station.

[0027] The working principle of the above embodiment is:

[0028] When the front roller conveyor platform transports the weighing plate to the bottom of the suction cup loading device, the push cylinder drives the blocking wheel to lift up in advance to block the weighing plate. At the same time, the blocking wheel is buffered and limited by the limit plate and buffer column to form a support. Then the push cylinder drives the upper push plate to lift up. The limit column of the upper push plate extends to the bottom of the weighing plate to limit and prevent it from moving. The weighing plate is lifted up and separated from the roller of the roller conveyor platform, thereby improving the stability of the stop. When the cleaned load is loaded by the suction cup loading device, The box is placed in the cross-shaped notch of the weighing plate, and then the push cylinder and the push cylinder retreat, so that the weighing plate continues to be transported. When there is a weighing plate at the bottom of the injection device, the lifting component and the blocking component are lifted up, and the weighing plate is restricted between the suction cup loading device and the injection device to form a pre-waiting. At the same time, when the weighing plate is moved to the bottom of the injection device, the lifting component and the blocking component are also lifted up to complete the limit and inject the product into the carrying box for collection. At the same time, the weighing plate displays the sample weight value. After the collection is completed, the weighing plate The weighing plate is moved to the docking conveyor platform, and the jacking assembly drives the docking conveyor platform to dock with the belt conveyor platform to complete the transportation. Then the jacking assembly on the rear roller conveyor platform drives the docking conveyor platform to dock with the belt conveyor platform. When the weighing plate is completely transported to the docking conveyor platform, the jacking assembly drives the docking conveyor platform to retreat, so that the weighing plate falls completely on the roller conveyor platform and is transported through the drying box to complete the drying operation. When the drying is completed, the weighing plate will display the dried value, which is convenient for the staff to record and analyze its moisture content. Until the weighing plate is moved to the left belt conveyor platform, the belt moving device and the lower top cylinder cooperate to drive the clamping cylinder to clamp the carrier box through the L-shaped splint and move it to the unloading position. At this time, the rotating cylinder drives the clamping cylinder to rotate through the rotating column, so that the dried product in the carrier box is poured out and collected, and the conveying mechanism circulates the weighing plate to realize automatic continuous production, improve the efficiency of product inspection, and reduce time costs.
