[0002] NdFeB magnetic materials are widely used in electronics, power machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields due to their excellent magnetic properties. Most of the third-generation rare earth permanent magnets used in the market are NdFeB, which is the strongest permanent magnet among contemporary magnets. Its main raw materials are rare earth metals praseodymium, neodymium, and gadolinium, accounting for about 29%-32.5%, metal element iron 63.95-68.65%, non-metallic element boron 1.1-1.2%, added dysprosium 0.6-8%, niobium 0.3-0.5%, aluminum 0.3-0.5%, copper 0.05-0.15% and other elements. In the production process of NdFeB magnets, NdFeB waste materials of about 20% of the raw material weight will be generated, including turning blocks, scrapped materials, water-abrasive materials and oil-immersed waste materials, etc., in addition to retired waste materials after the use of magnetic materials. Therefore, NdFeB waste has a good recycling prospect. When recycling NdFeB waste, it is necessary to sample the NdFeB waste and analyze the quality of the NdFeB waste based on the sample test structure.

[0003] In the prior art, for the sampling of NdFeB waste, most waste treatment companies use manual sampling with sampling rods, bag turning, cutting and mixed sampling, etc. These sampling processes have the disadvantages of large labor and sampler physical consumption, slow speed and many incomplete sampling.

[0013] Furthermore, the operating handle is in the shape of a long column, and the middle portion of the operating handle is concave to form a grip portion suitable for holding.

[0014] Furthermore, a power supply device and a control circuit board are also provided in the inner cavity of the operating handle, the control circuit board is electrically connected to the drive motor, and the power supply device is electrically connected to the control circuit board and the drive motor; the control circuit board is connected to control buttons embedded in the outer shell of the operating handle, and the control buttons include a power switch button, a sampling button and a sample unloading button; the power switch button is arranged on the power supply circuit between the power supply device and the drive motor, and is used to control the on-off of the power supply circuit; the sampling button sends a sampling signal to the control circuit board when triggered, and the control circuit board controls the drive motor to perform forward rotational motion in response to the sampling signal so that the sampling drill bit rotates forward for sampling; the sample unloading button sends a sample unloading signal to the control circuit board when triggered, and the control circuit board controls the drive motor to perform reverse rotational motion in response to the sample unloading signal so that the sampling drill bit rotates reversely for unloading.

[0015] Furthermore, the power supply device is a rechargeable battery and / or a wired AC power supply.

[0016] Furthermore, a rubber sleeve is provided on the outer periphery of the operating handle.

[0017] A method for sampling NdFeB waste, based on the sampler described above, is characterized by comprising the following steps:

[0034] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] At present, the annual processing capacity of various NdFeB waste recycling has reached more than 50,000 tons, and the NdFeB waste recycling industry has formed a huge scale. However, in the process of waste marketization, a waste circulation channel has been formed from the NdFeB waste production site to the NdFeB waste middlemen, and then from the middlemen to the NdFeB waste recycling enterprises. The transactions in the middle are settled through comprehensive sampling and based on the sample test and analysis data. The diversity of waste materials, the inconsistency of ingredients of various manufacturers, as well as the intervention of transportation extrusion and various human factors, make the NdFeB waste appear very different in softness and hardening, which makes sampling very difficult. Most waste treatment companies use sampling sticks for manual sampling, turning and cutting bags for mixed sampling, etc. These sampling processes have the disadvantages of large physical consumption of manpower and samplers, slow speed, and many inadequate sampling. In actual production, a portable and easy-to-operate sampling device is urgently needed.

[0039] Based on the above problems, the utility model provides a NdFeB waste sampler and usage method, which can effectively change the current backward manual sampling method, bring great convenience to actual operation, and at the same time the samples taken are more representative, thereby improving the credibility of the samples for both parties to the transaction.

[0040] like Figure 1 A sampler for NdFeB waste shown in Figure 3 includes an operating handle 2 and a sampling drill bit. A driving motor is provided in the inner cavity of the operating handle 2, and the output end of the driving motor is exposed outward from one end of the operating handle 2. One end of the sampling drill bit is connected to the output end of the driving motor through a connecting member 6. The sampling drill bit includes a drill rod 8 connected to the connecting member 6 and driven to rotate by the driving motor, and a spiral blade 7 spirally arranged on the outer periphery of the drill rod 8. The end of the drill rod 8 away from the connecting member 6 is provided with a tip structure 9 suitable for inserting into the waste to be sampled.

[0041] This NdFeB waste sampler uses a driving motor to drive the sampling drill bit to rotate so that the waste to be sampled adheres to the spiral blade 7 to achieve sampling. Compared with the existing manual sampling method using a sampling rod, it can make the sampling of plated NdFeB waste easier to achieve, which brings great convenience to the actual operation. At the same time, the samples taken are more representative, thereby improving the credibility of the samples; in addition, by changing the rotation direction of the sampling drill bit, the spiral blade 7 can realize automatic unloading, and the unloading operation is also more convenient.

[0042] In this embodiment, the operating handle 2 is in the shape of a long column as a whole. The middle part of the operating handle 2 is concave to form a hollow handle suitable for holding by hand. The cavity in the operating handle 2 is a handle cavity. The drive motor is installed in the handle cavity. One end of the handle cavity is sealed by the handle back cover 12. The operating handle 2 of this structure is mainly to fit the operator's hand in actual use. The operating handle 2 only needs to be well held by the human hand and its shape and appearance do not affect its use function; for example, the operating handle 2 can also be a cylindrical hollow handle. The operating handle 2 can be made of metal, wood, reinforced plastic or other high-strength materials; the outer side of the operating handle 2 is wrapped with a rubber sleeve 14 to increase the friction between the operating handle 2 and the hand, and at the same time enhance the comfort of the operating handle 2.

[0043] In this embodiment, a recessed portion suitable for accommodating the waste to be sampled is formed on the spiral surface of the spiral blade 7. When sampling, the waste to be sampled can be more easily attached to the recessed portion of the spiral blade 7, and when the sampler is pulled out, the waste to be sampled is not easy to fall off directly from the spiral blade 7, thereby preventing the waste to be sampled from falling during the transfer of the sampler and affecting the sampling.

[0044] Specifically, the tip structure 9 is conical, and the cone angle of the cone is 10° to 80°. The diameter range of the drill rod 8 is 3mm to 16mm; the blade width range of the spiral blade 7 is 2mm to 20mm, and the spiral angle of the spiral blade 7 is 15° to 60°. This arrangement facilitates the sampling drill bit to be inserted into the hardened NdFeB waste, thereby improving the reliability of the sample.

[0045] In this embodiment, the length direction of the drill rod 8 is the same as the length direction of the operating handle 2. Connection holes 3 are provided on opposite sides of the operating handle 2, and a booster handle 4 is detachably connected to the connection holes 3. The length direction of the booster handle 4 is perpendicular to the length direction of the drill rod 8; the booster handle 4 is a metal handle with a knurling structure at one end. In general sampling, the booster handle 4 is not installed on the operating handle 2; when sampling hardened waste with relatively high hardness, the booster handle 4 is installed on the connection holes 3 on opposite sides of the operating handle 2, and the booster handles 4 on both sides are held with both hands and pressed toward the direction of the drill rod 8, so that the rapid sampling of hard materials or hardened waste can be achieved.

[0046] In this embodiment, a power supply device and a control circuit board are also provided in the handle inner cavity 13, and the control circuit board is electrically connected to the drive motor, and the power supply device is electrically connected to the control circuit board and the drive motor. The control circuit board is connected to a control button embedded in the outer shell of the operating handle 2, and the control button includes a power switch button 10, a sampling button 5, and a sample unloading button; the power switch button 10, the sampling button 5, and the sample unloading button are all arranged at the front end of the operating handle 2 near the sampling drill bit and arranged side by side. The power switch button 10 is also arranged on the power supply circuit between the power supply device and the drive motor to control the on and off of the power supply circuit; the sampling button 5 sends a sampling signal to the control circuit board when it is triggered, and the control circuit board controls the drive motor to rotate forward in response to the sampling signal so that the sampling drill bit rotates forward to sample; the sample unloading button sends a sample unloading signal to the control circuit board when it is triggered, and the control circuit board controls the drive motor to rotate reversely in response to the sample unloading signal so that the sampling drill bit rotates reversely to unload the sample. By arranging a power switch button 10, a sampling button 5 and a sample unloading button on the operating handle 2, when sampling, automatic sampling can be achieved by pressing the power switch button 10 and the sampling button 5 in sequence. When unloading, automatic unloading can be achieved by pressing the power switch button 10 and the sample unloading button in sequence, which is convenient to operate.

[0047] Specifically, the power supply device is a rechargeable battery and a wired AC power supply; the rechargeable battery and the wired AC power supply are two independent power supply devices. When the wired AC power supply is connected, AC power is used to drive the drive motor to start; using a rechargeable battery for sampling is portable and flexible, and it is more powerful when connected to a wired AC power supply. When in use, the power supply mode can be selected according to the on-site conditions.

[0048] The present utility model also provides a method for sampling NdFeB waste, based on the above-mentioned sampler, which specifically includes the following steps:

[0049] S1, hold the operating handle 2 and press the power switch button 10 on the operating handle 2;

[0050] S2, press the sampling drill bit with pressure on the waste to be sampled, press the sampling button 5 on the operating handle 2, and the sampling drill bit rotates forward and drills into the center of the waste to be sampled;

[0051] S3, when the drilling depth of the sampling drill bit reaches the preset depth value, the power switch button 10 is pressed again, the sampling drill bit is pulled out after the power is turned off, and the sampling waste is attached to the sampling drill bit;

[0052] S4. Move the sampling drill bit with the waste material to be sampled attached to it into the sample container, press the power switch button 10 and the sample unloading button in sequence, and the sampling drill bit rotates in the opposite direction so that the waste material to be sampled attached to it falls into the sample container.

[0053] The sampling method of NdFeB waste provided by the utility model can realize the automation of sampling and unloading operations by pressing the power switch button 10, the sampling button 5 and the unloading button, and has the advantages of simple operation and easy implementation.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
