When the material taking grab 3 is driven by the first driving mechanism 4 to leave the position of the discharging pipe 5 (see the state of fig. 2A), the material taking cup 31 moves towards the lower material barrel 1, the friction force (resistance force) between the bottom cover ejector rod 33 and the bottom cover 32 enables the bottom cover 32 to slide along the guide groove until the bottom cover 32 abuts against the limiting mechanism of the guide groove, at the moment, the discharging port of the material taking cup 31 is covered and closed by the bottom cover (see the state of fig. 2B), and the pushing force of the limiting mechanism to the bottom cover 32 is greater than the friction force between the bottom cover ejector rod 33 and the bottom cover 32, so that the bottom cover 32 slides along with the material taking cup 31 towards the lower material barrel 1 until the material taking cup 31 extends into the lower material barrel 1 (at the moment, the discharging port is completely closed). When the material taking cup 31 receives the hot raw material and returns to the position of the bottom cover ejector rod 33 under the action of the first driving mechanism 4, the bottom cover ejector rod 33 contacts with the bottom of the bottom cover 32, the friction force (resistance force) between the bottom cover ejector rod 33 and the bottom cover 32 enables the bottom cover 32 to slide along the guide groove (the material taking cup continues to move under the action of the first driving mechanism 4, but the bottom cover 32 does not move or slightly moves), at the moment, the discharge hole at the bottom of the material taking cup 31 is gradually opened, and the hot raw material falls into the discharging pipe 5 from the discharge hole of the material taking cup 31.
In this embodiment, the guide groove is used for limiting the position of the bottom cover 32 and providing guidance, and the specific structural form thereof has various options and is not limited; the matching structure between the bottom cover top rod 33 and the bottom cover 32 has various forms, for example, the bottom cover top rod 33 can be a conical structure made of elastic material, and the elastic material is compressed at the bottom of the bottom cover 32 to generate larger friction resistance; or the bottom cover top rod 33 can also be in a spring structure, and a large frictional resistance is generated by contacting and compressing the spring through the bottom cover 32; the bottom cover plunger 33 may even be a magnet, and the bottom of the bottom cover 32 is provided with a metal material, so that the resistance is generated by the attraction force of the magnet. The above embodiments are merely exemplary illustrations for facilitating understanding of the bottom cover 32 slidably mounted at the bottom discharge opening of the material taking cup 31 in the present embodiment, and do not limit the specific structures of the material taking cup 31, the bottom cover 32, and the bottom cover push rod 33.
Obviously, the discharge grab 3 can be implemented in various configurations, as long as it is capable of performing the discharge and directing the hot raw meal into the discharge pipe 5. The above embodiments are merely exemplary of the implementation form of the material taking grab 3, and the equivalent modified or replaced structures on the basis are also within the disclosure range of the present invention.

Preferably, a position sensor 21 (for example, a travel switch installed at a position where the bottom cover ejector rod 33 and the bottom cover 32 touch each other or an optoelectronic position sensor installed at a side of the material taking pipe 2, which is located at an inlet of the material taking pipe 5 and close to the material taking barrel 1) for instructing the material taking cup 31 to start discharging is provided at a suitable position of the material taking pipe 2, when the material taking grab 3 returns and passes through the position sensor 21, a signal of the position sensor 21 is sent to the numerical control device 03, so as to trigger an opening event of the material taking valve 7, that is, after the numerical control device 03 receives the signal sent by the position sensor 21, the material taking valve 7 is controlled to open.
The automatic hot raw material detection device 02 is used for sampling and detecting hot raw materials obtained by the automatic hot raw material taking device 01 according to detection requirements without manual intervention. In the embodiment shown in fig. 1, the automatic detection device 02 for hot raw material comprises a sample preparation mechanism 10, a sampling mechanism 13 and a detection mechanism 12, wherein the sampling mechanism 13 is matched with the sample preparation mechanism 10 to take hot raw material from the blanking pipe 5 and prepare a sample 11 to be detected according to the detection requirement, the sampling mechanism 13 automatically sends the prepared sample 11 to a preset detection position, and the detection mechanism 12 automatically completes the detection work.
Specifically, in this embodiment, the detecting mechanism 12 is a fluorescence detector (i.e., an XRF detecting device for detecting the content of the relevant elements in the sample 11), and the sample 11 is required to be a flat-surfaced stacked sample with a certain thickness. In order to meet the requirements, the sample preparation mechanism 10 and the sampling mechanism 13 are matched to complete automatic sample preparation and automatic sampling operations.
As shown in fig. 1, the sample preparation mechanism 10 includes a sample preparation bin 101 and a pressing roller 102 or a scraper, the upper end of the sample preparation bin 101 is communicated with the tail end of the blanking pipe 5, the lower end is funnel-shaped, the funnel opening is communicated with the receiving mechanism 9, one side of the sample preparation bin 101 is further provided with a sampling opening 103 for the sampling mechanism 13 to go in and out, and the pressing roller 101 or the scraper is arranged above the sampling opening 103 of the sample preparation bin 101.
Preferably, the height of the pressing roller 101 or the scraper is adjustable, and the height of the pressing roller 101 or the scraper can be adjusted according to the specification and the size of the sample preparation mechanism 10, so that the prepared sample 11 to be measured keeps a preset thickness.
Referring to fig. 3A and 3B, the sampling mechanism 13 includes a sampling tray 131, a connecting rod 132, a tray guide 133 and a second driving mechanism 134, wherein the tray guide 133 is located below the detecting mechanism 12 and horizontally arranged, and one end of the tray guide extends into the sample preparation chamber 101 through the sampling port 103 of the sample preparation chamber 101, and preferably, the end of the tray guide located inside the sample preparation chamber 101 is provided with a downward bent inclined surface; the sampling tray 131 is arranged on the tray guide rail 133, one end of the connecting rod 132 is connected to the second driving mechanism 134, the other end of the connecting rod 132 is hinged to the sampling tray 131, the connecting rod 132 can be driven by the second driving mechanism 134 to do telescopic motion to drive the sampling tray 131 to do reciprocating motion along the tray guide rail 133, and the tray guide rail 133 provides guidance and support for the telescopic motion of the sampling tray 131; when the connecting rod 132 drives the sampling tray 131 to move to the downward slope of the tray guide 133, the sampling tray 131 slides down along the slope due to gravity, i.e. rotates clockwise along the hinge point with the connecting rod 132.
In this embodiment, the complete sample preparation, sampling and discharging operation includes the following steps:
the method comprises the following steps: firstly, the second driving mechanism 134 drives the connecting rod 132 to extend out, so as to push the sampling tray 131 into the sample preparation bin 101, so that the material receiving area of the sampling mechanism 13 (i.e. the material receiving area on the sampling tray 131) reaches the position (material receiving position) shown in fig. 3A;
step two: the second driving mechanism 134 drives the connecting rod 132 to extend continuously, the sampling tray 131 rotates clockwise after being separated from the tray guide rail 133, and the sample on the material receiving area of the sampling tray 131 (i.e. the sample prepared in the previous detection period) is poured into the funnel of the sample preparation bin 101, obviously, the extending distance of the connecting rod 132 and the inclined angle of the tray guide rail 133 determine the rotation angle of the sampling tray 131, in the design, the actual rotation angle of the sampling tray 131 is based on the fact that the sample can be completely poured, and the state after the sampling tray 131 rotates in this embodiment is as shown in fig. 3B. If the sample is prepared and sampled for the first time and no sample exists on the sampling tray 131, the step one can be directly skipped to the step four;
step three: the second driving mechanism 134 drives the connecting rod 132 to return to the position reached in the first step, and the sampling tray 131 rotates counterclockwise and retreats, returns to the original horizontal state, and returns to the material receiving position shown in fig. 3A;
step four: the material receiving area of the sampling tray 131 receives the hot raw materials falling from the blanking pipe 5 until the material receiving area of the sampling tray 131 is full of the hot raw materials (the material receiving time can be controlled by the opening time of the material taking valve 7, or the material receiving time can be directly set); it should be noted that in a cycle, all the hot raw materials obtained by the material taking grab 3 are all poured into the material discharging pipe 5 and fall into the sample preparation bin 101, and the design ensures that the materials are enough to fully pile the hot raw materials on the material receiving area of the tray 131, and the redundant or overflowed hot raw materials fall into the funnel-shaped lower end of the sample preparation bin 101 and are collected by the material receiving mechanism 9;
step five: the second driving mechanism 134 drives the connecting rod 132 to retract, the hot raw material on the sampling tray 131 contacts with the periphery of the pressing roller 101 or the lower surface of the scraper, and the pressing roller 101 or the scraper scrapes the hot raw material along with the movement of the sampling tray 131 (namely, the distance between the pressing roller 101 or the scraper and the bottom of the material receiving area of the sampling tray 131 is the required thickness of the sample to be measured);
step six: the sampling tray 131 moves to the detection position of the detection mechanism 12, and detection is performed.
The above operation process can be automatically completed under the control of the numerical control device 03, and can also be manually completed. Repeating the above process, and continuously and automatically detecting the element components and content of the hot raw material.
The operation process is suitable for a continuous detection process with short interval time. For the longer detection interval, the first to third steps (i.e. the process of pouring the hot raw material sample prepared in the previous detection period) of the above operation process can be performed immediately after the sixth step (i.e. the detection by the detection mechanism 12 is completed), and then the sampling tray 131 is withdrawn from the sample preparation chamber 101 and stays on the guide rail 135. The advantage of this is that the stay time of the hot raw material at the detecting position is short, which avoids the hot raw material falling outside the system under the condition of external vibration; meanwhile, the center of gravity of the sampling tray 131 completely falls on the tray guide 133 during a long waiting time, and abrasion of the hinge point with the link 132 is avoided. When the control logic is set in this way, in the next detection period, the sampling tray 131 does not need to perform the second step and the third step after extending into the sample preparation bin 101, and can perform the fourth step to the sixth step.
In another embodiment, as shown in fig. 4, the sampling mechanism 13 includes a sampling belt 135 and a second driving mechanism 134, which are horizontally arranged, one end of the sampling belt 135 extends into the sample preparation bin 101 from the sampling port 103, and the other end is located below the detecting mechanism 12; after the material receiving area of the sampling belt 135 receives the hot raw materials, the material receiving area of the sampling belt 135 moves out of the sample preparation bin 101 under the driving of the second driving mechanism 134, and the pressing roller 101 or the scraper scrapes the hot raw materials; the detection is started when the hot raw material to be scraped is sent to the detection position of the detection mechanism 12; after the detection is finished, the sampling belt 135 is reversed to bring the sample back to the sample preparation bin 101, and by prolonging the reversing time of the belt, the hot raw material sample falls into the lower funnel of the sample preparation bin 101 from the end, extending into the sample preparation bin 101, of the sampling belt 135.
Referring to fig. 5, the numerical control device 03 is electrically or signal connected to the first driving mechanism 4, the second driving mechanism 134, the detecting mechanism 12, the position sensor 21, and the driving mechanisms of the vibrating mechanism 6, the material taking valve 7, and the cooling mechanism 8 to control the whole sampling and detecting process, and receive and record the detection result uploaded by the detecting mechanism 12 for analysis and processing. Further, the numerical control device 03 can display the analysis and processing results through the display screen 031, or upload the analysis and processing results to the database of the upper-level management system for further analysis.

Step S2, sample preparation: the numerical control device 03 sends a control instruction to the second driving mechanism 134 to drive the material receiving area (the sampling tray 131 or the sampling belt 135) of the sampling mechanism 13 to extend into the material receiving position in the sample preparation bin 101 of the sample preparation mechanism 10.
Step S3, automatically taking materials: the numerical control device 03 sends a control instruction to the first driving mechanism 4, the first driving mechanism 4 drives the material taking grab bucket 3 to extend into the material discharging barrel 1 to receive the material, after the preset time length T1 is delayed, the material taking grab bucket 3 is driven to retract to an inlet of the material discharging barrel 5, the position sensor 21 is triggered to send a signal when the material taking grab bucket 3 retracts to the set position, and the numerical control device 03 receives the signal and controls the material taking valve 7 to be opened.
Preferably, the cooling mechanism 8 is activated before the material is taken, and the vibration mechanism 6 is activated at the same time as the material take-off valve 7 is opened. When the blanking is started, the hot raw material enters the blanking pipe 5 under the action of the vibration mechanism, and enters the sample preparation bin 101 of the sample preparation mechanism 10 through the temperature reduction of the cooling mechanism 8, and falls on the material receiving area (the sampling tray 131 or the sampling belt 135) of the sampling mechanism 13.
It should be noted that the timing of starting step S3 may be before step S2 or at any time after step S2 is started, and it is only necessary to ensure that the material receiving area of the sampling mechanism 13 reaches the material receiving position when the material taking valve 7 is opened.
Step S4, automatic sample preparation: after the material taking valve 7 is opened for a time period T2, the numerical control device 03 controls the material taking valve 7 to be closed, and controls the second driving mechanism 134 to drive the material receiving area (the sampling tray 131 or the sampling belt 135 full of material) of the sampling mechanism 13 to exit from the sample preparation bin 101, and in this process, the material in the material receiving area is made into the sample 11 to be detected by the detecting mechanism 12 under the action of the material pressing roller 102 or the scraper.
Step S5, automatic detection: the numerical control device 03 controls the second driving mechanism 134 to drive the sample 11 to be detected on the material receiving area of the sampling mechanism 13 to move to the detection position of the detection mechanism 12, starts the detection mechanism 12 to start detection, and sends a signal of detection end to the numerical control device 03 after the detection of the detection mechanism 12 is finished.
Step S6, automatic discharging: the numerical control device 03 controls the second driving mechanism 134 to drive the sample 11 to be tested located in the material receiving area of the sampling mechanism 13 to return to the sample preparation bin 101 of the sample preparation mechanism 10, pour the sample 11 to be tested into the material receiving mechanism 9, then return to the tray rail 135, and return to step S2, or directly stop at the material receiving position, and return to step S3.
