[0002] Oatmeal is usually made from oats. Before producing oatmeal using oats as raw materials, the oats need to undergo a series of tests, among which heavy metal testing is an important part of oatmeal testing that cannot be ignored. Heavy metal pollution is another major hidden danger to food safety. The heavy metal content in oatmeal, such as lead, mercury, and cadmium, exceeds the limit standard, which may cause potential harm to human health. At present, when oats are tested for heavy metals, due to the limited detection capacity of heavy metal detection equipment, some oats are generally randomly selected from a batch for testing, or different batches are tested in multiple times. However, the two testing methods have the disadvantages that the test samples are not representative or the staff's operation is cumbersome, which makes it inconvenient for the staff to perform heavy metal testing on oats.

[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a heavy metal detector body 1, a bearing base plate 2 is fixedly connected to the top of the heavy metal detector body 1, a mixing tube 21 is detachably connected to the top of the bearing base plate 2, an extension rod 22 is fixedly connected to the top of the bearing base plate 2, a linkage plate 3 is slidably connected to the outer side of the extension rod 22, a grinding disc 31 is provided below the linkage plate 3, a driving motor 32 is fixedly connected between the linkage plate 3 and the grinding disc 31, an adjustment block 33 is slidably connected to the outer side of the linkage plate 3, the adjustment block 33 is engaged with the extension rod 22, a scraper ring 4 is provided between the grinding disc 31 and the mixing tube 21, and the scraper ring 4 corresponds to the position of the grinding disc 31 and the mixing tube 21.
[0017] In this embodiment: the heavy metal detector body 1 is used to detect the heavy metal content of oatmeal raw materials. Three groups of coils are distributed inside the heavy metal detector body 1, namely the central transmitting coil and two equal receiving coils. The oscillator connected to the middle transmitting coil generates a high-frequency variable magnetic field. In the idle state, the induced voltages of the receiving coils on both sides cancel each other out before the magnetic field is disturbed and reach a balanced state. Once metal impurities enter the magnetic field area, the magnetic field is disturbed, and this balance is broken. The induced voltages of the two receiving coils cannot be offset. The unoffset induced voltage is amplified and processed by the control system, and an alarm signal (metal impurities are detected) is generated. The system can use the alarm signal to drive an automatic removal device, etc., so as to eliminate the metal impurities. Outside the production line, after the sample is digested, all forms of heavy metals are converted into ion forms, and color is developed after adding relevant detection reagents. Within a certain concentration range, the depth of the solution color is proportional to the content of heavy metals, and then the content value is determined by the instrument to complete the detection of the heavy metal content of the oatmeal raw materials. The bearing base plate 2 fixed on the top of the heavy metal detector body 1 is used to support and connect various components. The mixing cylinder 21 detachably connected to the top of the bearing base plate 2 is used to store oatmeal raw material samples so that the raw material samples can be processed by other components. The extension rod 22 fixed on the top of the bearing base plate 2 is used to extend the bearing base plate 2, and the extension rod 22 can support the linkage plate 3, so that the linkage plate 3 can be on the outside of the extension rod 22. The linkage plate 3 is provided with a grinding disc 31 below, and a driving motor 32 is installed between the grinding disc 31 and the linkage plate 3. When the staff puts different batches of random oatmeal raw materials into the inner side of the mixing cylinder 21, the staff can move the linkage plate 3 vertically, and the grinding disc 31 corresponds to the position of the mixing cylinder 21, so that the grinding disc 31 can enter the mixing cylinder 21 and contact the oatmeal raw materials inside the mixing cylinder 21. Then the staff can slide the adjustment block 33 to make the adjustment block 33 engage with the extension rod 22, thereby ensuring that the linkage plate 3 can be continuously located in the appropriate position. Then the staff can start the driving motor 32 to make the grinding disc 31 rotate inside the mixing cylinder 21, thereby completing the mixing of the oatmeal raw materials inside the mixing cylinder 21. For the purpose of crushing and mixing, after the grinding disc 31 completes the crushing and mixing work of the oatmeal raw materials, the staff can slide the interlocking plate 3 vertically to disengage the grinding disc 31 from the inside of the mixing barrel 21, and the grinding disc 31 will contact the scraper ring 4 when moving vertically upward, so that the oatmeal raw material powder attached to the outer wall of the grinding disc 31 will be scraped off, and because the position of the scraper ring 4 corresponds to the mixing barrel 21, the scraped oatmeal raw material powder will fall into the mixing barrel 21, and then the staff can put the oatmeal raw material powder inside the mixing barrel 21 into the heavy metal detector body 1, and complete the simultaneous detection of different batches through the heavy metal detector body 1, thereby ensuring the representativeness of the oatmeal raw material samples put into the heavy metal detector body 1.
[0018] A limiting block 23 is fixedly connected to the top of the supporting base plate 2, and a positioning groove 211 is provided at the bottom of the mixing cylinder 21; the limiting block 23 fixed at the top of the supporting base plate 2 is used to position the mixing cylinder 21, and a matching positioning groove 211 is provided at the bottom of the mixing cylinder 21, so that when the staff places the mixing cylinder 21 on the top of the supporting base plate 2, the limiting block 23 can slide to the inside of the positioning groove 211, thereby ensuring that when the grinding disc 31 rotates inside the mixing cylinder 21, the mixing cylinder 21 will not move synchronously with the grinding disc 31, so that the oatmeal materials inside the mixing cylinder 21 will be crushed and mixed.
[0019] An alignment groove 221 is provided inside the extension rod 22, and an expansion block 222 is fixedly connected to one side of the extension rod 22; the alignment groove 221 provided inside the extension rod 22 is used to make way for the insertion of the adjustment block 33, so that when the staff slides the linkage plate 3 to a suitable position, the position of the linkage plate 3 can be engaged and limited by sliding the adjustment block 33 into the alignment groove 221, thereby ensuring that the linkage plate 3 can be continuously located in a suitable position, so that the grinding disc 31 can complete the crushing and mixing of the oatmeal raw materials inside the mixing barrel 21, and the expansion block 222 fixed on one side of the extension rod 22 is used to limit the linkage plate 3, thereby preventing the linkage plate 3 from slipping out from the outside of the extension rod 22.
[0020] A clearance groove 34 is provided inside the linkage plate 3, and the linkage plate 3 is slidably connected to the outside of the extension rod 22 through the clearance groove 34; the clearance groove 34 provided inside the linkage plate 3 is used to make way for the penetration of the extension rod 22. This allows the staff to slide the linkage plate 3 on the outside of the extension rod 22, so that the grinding disc 31 can slide into the mixing cylinder 21, and through the drive of the drive motor 32, the oatmeal raw materials in the mixing cylinder 21 are crushed and mixed.
[0021] A fixing rod 41 is fixedly connected between the scraper ring 4 and the extension rod 22; the fixing rod 41 fixed between the scraper ring 4 and the extension rod 22 is used to fix the position of the scraper ring 4, so that the scraper ring 4 can continue to maintain a corresponding position with the grinding disc 31 and the mixing cylinder 21, and then when the grinding disc 31 slides out from the inside of the mixing cylinder 21, it will slide from the inside of the scraper ring 4, so that the scraper ring 4 can scrape the oatmeal raw material powder attached to the outer wall of the grinding disc 31.
[0022] The working principle and use process of the utility model are as follows: when the staff needs to test the heavy metal content of the oatmeal raw materials, the staff can take out an appropriate amount of oatmeal raw materials from different batches, and then the staff can place the mixing tube 21 on the top of the supporting bottom plate 2, so that the limit block 23 is inserted into the positioning groove 211, and then the staff needs to put all the taken oatmeal raw material samples into the mixing tube 21, and then slide the linkage plate 3 to drive the grinding disc 31 to move until the grinding disc 31 moves to the inside of the mixing tube 21 and contacts the oatmeal raw materials. At this time, the staff can slide the adjustment block 33 to the linkage plate 3 and the alignment groove 221 to limit the position of the linkage plate 3, and then the staff can start the drive motor 32 to drive the grinding disc 31 to rotate. The grinding disc 31 is During rotation, the oatmeal raw material samples inside the mixing cylinder 21 will be crushed and mixed. After the oatmeal raw material samples are evenly mixed, the staff can slide the grinding disc 31 out of the mixing cylinder 21. Since the position of the scraper ring 4 corresponds to the grinding disc 31, the grinding disc 31 will slide from the inside of the scraper ring 4 when sliding out, so that the scraper ring 4 can scrape off the oatmeal raw material powder attached to the outer wall of the grinding disc 31. Since the position of the scraper ring 4 corresponds to the mixing cylinder 21, the scraped oatmeal raw material powder will fall into the mixing cylinder 21. Then the staff can pour the evenly mixed oatmeal raw material sample inside the mixing cylinder 21 into the heavy metal detector body 1, and simultaneously complete the detection of oatmeal raw material samples of different batches through the heavy metal detector body 1, thereby reducing the operating steps of the staff while ensuring the representativeness of the detected samples.
