DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] To enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] The core of the present utility model is to provide a sampling device, and the structural schematic diagram of a specific embodiment thereof is as Figures 1 to 3 shown, which is called the first specific embodiment, and includes a rotary driver 10, a rotating rod 20, a funnel housing 30 and a sampling tube 40;

[0040] The funnel housing 30 is fixedly connected to the rotating rod 20, and the rotating rod 20 is disposed on the axis of the funnel housing 30;

[0041] The rotary driver 10 drives the funnel housing 30 to rotate through the rotating rod 20;

[0042] The sampling tube 40 is disposed on the outer surface of the funnel housing 30, and one end of the sampling tube 40 away from the funnel housing 30 is a spoon-shaped pipe orifice;

[0043] The sampling tube 40 rotates with the funnel housing 30, and the lowest point of the spoon-shaped pipe orifice during the rotation corresponds to the sampling surface.

[0044] Of course, as described above, during the rotation of the sampling tube 40 with the rotating rod 20, there is a height change in the vertical direction. Therefore, the rotating rod 20 is not vertically disposed, but should be horizontally disposed or have a certain angle with the horizontal direction, which can be selected according to the actual situation, and the present utility model does not make a limitation here. The sampling surface is the surface where the sample to be taken is placed.

[0045] As a preferred embodiment, the rotating rod 20 is horizontally disposed, and the sampling tube 40 is perpendicular to the rotating rod 20.

[0046] In this preferred embodiment, during the rotation of the sampling tube 40, it is always in the same vertical plane, so that when the sampling tube 40 rotates to the high point, the resistance of the sample in the sampling tube 40 rolling into the funnel housing 30 is the smallest, ensuring the consistency of the amount of the sample taken each time, and at the same time preventing incomplete derivation of the single sampling and the residual sample from contaminating the samples of subsequent samplings, resulting in inaccurate test results.

[0047] Preferably, the funnel housing 30 is a conical housing.

[0048] The funnel housing 30 is designed in a conical shape, which can ensure that there are no obvious edge grooves in the internal chamber of the funnel housing 30. The samples obtained by sampling can slide down along the smooth inner wall of the internal chamber, further reducing the resistance during the sliding process and ensuring the reliability of the equipment operation. Of course, other shapes of funnel housings 30 can also be selected, such as a triangular pyramid-shaped housing or a quadrangular pyramid-shaped housing, etc., which can be selected according to the actual situation.

[0049] Further, it includes a plurality of sampling tubes 40;

[0050] A plurality of the sampling tubes 40 are arranged at equal intervals on the outer surface of the funnel housing 30.

[0051] In this preferred embodiment, a plurality of sampling tubes 40 are arranged at equal intervals on the outer surface of the funnel housing 30. During the rotation of the funnel housing 30, a plurality of the sampling tubes 40 sequentially reach the sampling surface to obtain samples and then leave, which can greatly improve the sampling efficiency. By controlling the rotation angle, the sampling quantity can be controlled, and the versatility of the sampling equipment provided by the present utility model is improved.

[0052] As a specific embodiment, the rotating rod 20 includes an internal extension section located in the internal chamber of the funnel housing 30;

[0053] The sampling equipment further includes a support rod 31;

[0054] Both ends of the support rod 31 are respectively connected to the internal extension section and the inner surface of the funnel housing 30.

[0055] In this preferred embodiment, the support rod 31 supports between the funnel housing 30 and the rotating rod 20, reducing the probability that the funnel housing 30 deforms due to its own weight or external impact during long-term use, and further improving the service life and operation stability of the equipment.

[0056] In addition, the sampling tube 40 further includes a buffer plate;

[0057] The buffer plate is arranged outside the spoon-shaped pipe orifice.

[0058] By arranging a buffer plate outside the spoon-shaped pipe orifice, the rigid collision between the sampling tube 40 and the sampling surface can be significantly reduced, the wear between the two can be reduced, and the service life and working stability of the equipment can be improved. Further, when the sampling surface is the belt 12, the buffer plate is a wear-resistant buffer plate (such as a rubber plate), which can make the sampling tube 40 fit closely with the belt 12 as much as possible without damaging the belt 12, ensuring that the fine materials at the bottom of the belt 12 can be taken out and truly reflecting the material properties of the materials.

[0059] As another specific embodiment, it further includes a frame 50;

[0060] The rotary drive 10 includes a reduction motor 11, a belt 12 and a turntable 13;

[0061] The reduction motor 11 and the turntable 13 are located in the same vertical plane, and the reduction motor 11 drives the turntable 13 to rotate through the belt 12;

[0062] The rotating rod 20 is fixedly connected to the rotating shaft of the turntable 13.

[0063] In this specific embodiment, the sampling device includes a frame 50 for supporting other structures, and the remaining structures are all arranged on the frame 50, which provides convenience for the installation of the sampling device. In addition, the rotary drive 10 is further divided into the reduction motor 11, the belt 12 and the turntable 13. The mechanism that provides power (i.e., the reduction motor 11) is connected to the structure directly connected to the rotating rod 20 (i.e., the turntable 13) through the belt 12, rather than a rigid connection, which gives the sampling device greater spatial freedom during installation and makes the sampling device have better versatility. Refer to Figure 1 , Figure 1 In [reference], the reduction motor 11 is arranged directly above the turntable 13. Of course, according to the actual situation, the reduction motor 11 can also be arranged directly below the turntable 13, which can be selected according to the actual situation. In this utility model, it is not limited as long as it is ensured that the reduction motor 11 and the turntable 13 are located in the same vertical plane. Figure 1 Figure 4 is a right view of a specific embodiment corresponding to the present utility model, Figure 2 Figure 5 is a corresponding front view, Figure 3 Figure 6 is a corresponding top view.

[0064] Furthermore, it further includes a control box 60;

[0065] The control box 60 is arranged on the frame 50 and is electrically connected to the reduction motor 11.

[0066] In this preferred embodiment, the control box 60 is directly arranged on the frame 50, that is, relevant staff can directly perform on-site sampling by operating the control box 60, reducing the intermediate operation process, greatly facilitating the operation of the staff, and improving the sampling efficiency.

[0067] Furthermore, the sampling device in the present utility model can be controlled in two ways: manual operation and automatic operation, including:

[0068] 1. Manual operation: Press the start button of the sampling device, and the sampling device will rotate once and stop at a predetermined position.

[0069] 2. Automatic operation: The automatic operation is carried out under the control of electrical components. After receiving the instruction, the sampling device runs automatically, rotates once, and intercepts a sub-sample from the material surface. After the entire automatic operation process is completed, the system waits for the next signal. The sampling time can be adjusted arbitrarily from 1 to 9999 s. After the set interval time, an automatic sampling action is carried out again until the sampling volume meets the requirements.

[0070] Maintenance of the sampling device:

[0071] 1. The sampling device should be cleaned twice a week to check whether there is any debris in the internal chamber of the funnel housing 30.

[0072] 2. The gear oil of the reduction motor 11 should be replaced every three months.

[0073] 3. Lubricating oil should be added to the bearings every three months.

[0074] 4. The proximity switch of the control box 60 should be checked once a month for looseness or out-of-control phenomenon. The dust on the surface of the proximity switch should be cleaned once a week. Excessive dust may cause the sampling head to get out of control (continuous material taking and inability to stop).

[0075] 5. The bolts of the equipment should be checked every two months for looseness, and the loose ones should be tightened in time.

[0076] 6. Overloading operation of the equipment is strictly prohibited.

[0077] Troubleshooting of common faults:

[0078] 1. Check whether the proximity switch is normal.

[0079] 2. Check whether the wiring terminals are loose.

[0080] 3. Check whether the reduction motor 11 lacks oil.

[0081] 4. Check whether the rotary drive 10 is normal.

[0082] Safety requirements:

[0083] 1. There should be obvious warning signs at the equipment site.

[0084] 2. Do not approach when the equipment is running.

[0085] 3. The power supply should be disconnected before checking and repairing the equipment.

[0086] Furthermore, it also includes a collection bag 70;

[0087] The collection bag 70 is arranged below the edge of the housing of the funnel housing 30 and is located in the same vertical plane as the axis of the funnel housing 30.

[0088] The housing edge of the funnel housing 30 refers to the outer edge of the funnel, and can also be considered as the edge where the obtained sample slides out of the funnel housing 30, and is located in the same vertical plane as the axis of the funnel housing 30, which means that the collection bag 70 is located directly below the funnel housing 30. After the sample falls into the funnel housing 30 through the sampling tube 40, it will automatically slide into the collection bag 70, which further facilitates the collection of the sample.

[0089] As another specific embodiment, the sampling surface is a conveyor belt;

[0090] The rotation direction of the rotating rod 20 is opposite to the conveying direction of the conveyor belt.

[0091] The rotation direction of the rotating rod 20 is opposite to the conveying direction of the conveyor belt, which means that the moving direction of the sampling tube 40 is opposite to the conveying direction of the conveyor belt, so a larger amount of samples can be obtained and the sampling amount is more stable.

[0092] The problems solved by the present utility model mainly include using equipment sampling instead of manual sampling to achieve uniform, representative, accurate and reliable analysis results of the obtained samples, reducing the work intensity, and ensuring safety, etc. It is a sampling device made according to the characteristics of round granular solid materials, such as easy rolling under downward force, large roundness of particles, non-bonding and non-hygroscopic in a short time, etc., and solves the problems of uneven, unrepresentative, untimely and unsafe samples caused by manual sampling.

[0093] In a specific embodiment of actual production, the sampling device is installed in the middle of the conveyor belt 12 for transporting production materials. After the production materials are transported by the belt 12, the sampling device, under the control of the controller, intercepts a full-section sub-sample in the middle of the conveyor belt 12, and then rotates the rotating rod 20 through the rotary driver 10 to transport each obtained sub-sample to the funnel housing 30, where it is mixed in the funnel housing 30 and then manually mixed again, and a certain amount of samples for analysis are obtained through a standardized reduction method for analysis.

[0094] Furthermore, it includes three sampling tubes 40 arranged along the width direction of the conveyor belt;

[0095] The three sampling tubes 40 respectively correspond to the middle bandwidth area 01, the left bandwidth area 03 and the right bandwidth area 02 of the conveyor belt.

[0096] Specifically, there are three equally spaced sampling tubes 40 on the funnel housing 30 and they are fixed to the funnel housing 30. After the controller sets the rotation frequency and the device receives relevant command information, the three sampling tubes 40 rotate simultaneously, intercepting equal amounts of materials on the belt 12 respectively, and taking samples at three points on the left side (i.e., the left bandwidth area 03), the right side (i.e., the right bandwidth area 02), and the middle (i.e., the middle bandwidth area 01) of the belt 12 for mixing to make the sample more representative. Or by manually rotating the funnel housing 30 to make the three sampling tubes 40 all rotate, intercepting equal amounts of materials on the belt 12 respectively, and taking samples at three points on the left side, the right side, and the middle of the belt 12 for mixing to make the sample more representative. For reference, Figure 4 , Figure 4 is a top view schematic diagram of the corresponding conveyor belt. With the conveying direction of the conveyor belt as the front, the middle bandwidth area 01, the left bandwidth area 03, and the right bandwidth area 02 are determined.
