Description

Technical Field

[0001] This utility model relates to the field of material sampling technology, specifically to an automatic raw material sampling device. Background Technology

[0002] Representativeness of raw material sampling has always been a major challenge in bulk commodity trade settlement. Common sampling methods include systematic sampling, stratified sampling, truck / railway sampling, and bagged sampling. Among these, systematic sampling is free of systematic errors, ensuring good sample representativeness and eliminating human intervention. The other sampling methods may introduce systematic errors and allow for human intervention, thus failing to guarantee the representativeness of raw material samples.

[0003] In related technologies, systematic sampling is currently the most common method for material sampling. Although systematic sampling provides good representativeness, it requires automatic sample delivery, automatic sampling, automatic sample preparation, and automatic sample transfer or stacking, which leads to high technical difficulty and investment costs. It cannot guarantee that the samples taken can more accurately represent the overall characteristics of bulk materials, resulting in unreliability in the basis for bulk material trade settlement.

[0004] Therefore, there is an urgent need for an automatic raw material sampling device that, in conjunction with a systematic sampling method, can achieve automatic sample delivery, automatic sampling, automatic sample preparation, and automatic sample transfer or stacking; ensuring that the samples taken can more accurately represent the overall characteristics of bulk materials and provide a more reliable basis for trade settlement. Utility Model Content

[0005] The purpose of this invention is to provide an automatic raw material sampling device to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic raw material sampling device includes:

[0008] A material conveyor belt, wherein raw materials are provided at the front end of the material conveyor belt and a sampling station is provided at the rear end of the material conveyor belt;

[0009] The sampling station is equipped with a transfer belt at its tail end, which is connected to the sample preparation system.

[0010] A transfer conveyor belt is installed on one side of the sampling station and is connected to the return material yard;

[0011] The sampling station is equipped with a sampling trough at its bottom.

[0012] The automatic raw material sampling device according to this scheme has at least the following technical advantages:

[0013] This automatic raw material sampling device, combined with a systematic sampling method, automates a series of processes from raw material transportation to sampling, transfer, and sample preparation. Throughout the process, it reduces the impact of human factors on sampling results, avoids systematic errors caused by improper operation or human intervention, improves the fairness and objectivity of sampling results, reduces the labor intensity of staff, improves work efficiency, and ensures that the samples taken can more accurately represent the overall characteristics of bulk materials, providing a more reliable basis for trade settlement.

[0014] As a further improvement of this utility model, the material conveyor belt is a lifting conveyor belt.

[0015] As a further embodiment of this utility model: a hopper is provided at the front end of the lifting conveyor belt, and an unloading vehicle is provided on one side of the hopper, through which raw materials are unloaded into the hopper.

[0016] As a further improvement of this utility model, a plate feeder is provided at the bottom of the hopper.

[0017] Because the incoming material conveyor belt is a lifting conveyor belt, a hopper is installed at the front end of the lifting conveyor belt, and an unloading car is installed on one side of the hopper. The raw materials are unloaded into the hopper through the unloading car. The hopper serves as a buffer and storage unit for the raw materials. After the unloading car unloads the raw materials into the hopper, the hopper can stably supply raw materials to the lifting conveyor belt according to the operation of the incoming material conveyor belt and the needs of the sampling station, avoiding interruptions in the raw material supply caused by discontinuity in the unloading of the unloading car or other external factors. Furthermore, through the plate feeder, the hopper can flexibly control the amount of raw materials supplied to the lifting conveyor belt, optimizing the efficiency of raw material use and avoiding blockages caused by excessively fast material conveying or insufficient material supply caused by excessively slow material conveying. This ensures that the sampling process can be carried out continuously and stably, guaranteeing the stability of the entire sampling device.

[0018] As a further improvement of this utility model, the incoming material conveyor belt is a retractable conveyor belt.

[0019] As a further embodiment of this utility model: a material feeder is provided at the front end of the retractable conveyor belt, and a material pile is provided at the front end of the material feeder.

[0020] Because the incoming material conveyor belt is a retractable conveyor belt, a material feeder is installed at the front end of the retractable conveyor belt, and a material pile is installed at the front end of the material feeder. The shape of the material pile gradually decreases and changes during the continuous feeding process. Through the retractable conveyor belt, the retraction and adjustment can be made according to the actual situation of the material pile, and the material feeder can be used to smoothly transport the raw materials to the sampling station, which improves the working range of the material feeder, ensures the efficiency of raw material collection, and thus improves the stability and continuity of raw material sampling.

[0021] As a further improvement of this utility model, a movable support roller is provided at the bottom of the retractable conveyor belt.

[0022] Since different raw materials are stored in different locations within the same area, the retractable conveyor belt can be flexibly moved to different material storage locations by installing movable support rollers at the bottom of the belt. This allows for easy material removal operations for different types and storage locations, greatly enhancing the adaptability of the entire sampling device to different raw material storage layouts. It eliminates the need for a separate sampling and conveying device for each storage area, thus improving the device's versatility and efficiency.

[0023] As a further embodiment of this utility model, it also includes a sampling station platform, wherein the sampling station is disposed on the top of the sampling station platform.

[0024] Since it also includes a sampling station platform, which is located on top of the sampling station platform, the arrangement of the sampling station platform realizes the layered utilization of space. Placing the sampling station on the top of the platform makes the layout of the entire sampling device more compact and reasonable. In addition, the sampling station has a certain height, allowing the raw materials to be transported by their own weight and through connecting pipes to the transfer belt, transfer conveyor belt or sampling tank, which facilitates the connection between different processing of the raw materials and improves the raw material transfer efficiency.

[0025] As a further embodiment of this utility model: the sampling station is respectively equipped with a sampling conveying pipe, a sample preparation conveying pipe and a return material conveying pipe, the sampling conveying pipe is connected to the sampling trough, the sample preparation conveying pipe is connected to the front end of the transfer belt, and the return material conveying pipe is connected to the transfer conveyor belt.

[0026] Because the sampling station is equipped with sampling conveyor pipes, sample preparation conveyor pipes, and return material conveyor pipes, with the sampling conveyor pipes connected to the sampling tank, the sample preparation conveyor pipes connected to the front end of the transfer belt, and the return material conveyor pipes connected to the transfer belt, the raw materials, after entering the sampling station, are sampled using a systematic sampling method. The raw materials are moved through the sampling conveyor pipes to the sampling tank at certain mass or time intervals to collect samples. This ensures that the collected samples cover as many parts of the raw materials as possible, more accurately reflecting the quality characteristics of the entire batch of raw materials and providing a more reliable basis for trade settlement. Furthermore, some raw materials are promptly and accurately transported to the sample preparation system via the sample preparation conveyor pipes and transfer belts for testing of the raw material's composition, weight, moisture content, and other information, and for subsequent sample preparation. Meanwhile, excess raw materials are transported to the return material yard via the return material conveyor pipes and transfer belts for storage, eliminating the need to use all raw materials for testing or sample preparation, avoiding resource waste, and reducing enterprise production costs.

[0039] like Figure 1 and Figure 2 The present invention provides an automatic raw material sampling device, comprising: a material conveyor belt 1, with raw material disposed at the front end of the material conveyor belt 1 and a sampling station 2 disposed at the rear end of the material conveyor belt 1; a transfer belt 3 disposed at the rear end of the sampling station 2 and connected to the sample preparation system; a transfer belt 4 disposed on one side of the sampling station 2 and connected to the return material yard; and a sampling trough 5 disposed at the bottom of the sampling station 2.

[0040] During use, the raw materials are transported to the sampling station 2 via the incoming material conveyor belt 1. The sampling station 2 transports the sampled raw materials to the sampling tank 5 according to a certain mass or time interval. The sampling station 2 also transports a portion of the raw materials to the sample preparation system via the transfer belt 3 for subsequent testing and sample preparation. At the same time, the sampling station 2 transports the excess raw materials to the return material yard via the transfer conveyor belt 4 for storage, so that they can be used later.

[0041] Specifically, this automatic raw material sampling device, combined with a systematic sampling method, automates a series of processes from raw material transportation to sampling, transfer, and sample preparation. Throughout the process, it reduces the impact of human factors on sampling results, avoids systematic errors caused by improper operation or human intervention, improves the fairness and objectivity of sampling results, reduces the labor intensity of staff, improves work efficiency, and ensures that the samples taken can more accurately represent the overall characteristics of bulk materials, providing a more reliable basis for trade settlement.

[0042] like Figure 1 As shown, in one embodiment, the material conveyor belt 1 is a lifting conveyor belt, and a hopper 6 is provided at the front end of the lifting conveyor belt. A discharge car 7 is provided on one side of the hopper 6. The raw material is discharged into the hopper 6 through the discharge car 7. A plate feeder 8 is provided at the bottom of the hopper 6.

[0043] Specifically, since the incoming material conveyor belt 1 is a lifting conveyor belt, a hopper 6 is set at the front end of the lifting conveyor belt, and an unloading car 7 is set on one side of the hopper 6. The raw materials are unloaded into the hopper 6 through the unloading car 7. The hopper 6 serves as a buffer and storage for the raw materials. After the unloading car 7 unloads the raw materials into the hopper 6, the hopper 6 can stably supply raw materials to the lifting conveyor belt according to the operation of the incoming material conveyor belt 1 and the needs of the sampling station, avoiding interruptions in the raw material supply caused by discontinuity in the unloading of the unloading car 7 or other external factors. Moreover, through the plate feeder 8, the hopper 6 can flexibly control the amount of raw materials supplied to the lifting conveyor belt, optimize the efficiency of raw material use, avoid blockage caused by excessively fast raw material conveying or insufficient raw material supply caused by excessively slow raw material conveying, ensure that the sampling process can be carried out continuously and stably, and guarantee the stability of the entire sampling device.

[0044] like Figure 2 As shown, in another embodiment, the material conveyor belt 1 is a retractable conveyor belt, and a material feeder 9 is provided at the front end of the retractable conveyor belt, and a material pile 10 is provided at the front end of the material feeder 9.

[0045] Specifically, since the incoming material conveyor belt 1 is a retractable conveyor belt, a material feeder 9 is set at the front end of the retractable conveyor belt, and a material pile 10 is set at the front end of the material feeder 9; the shape of the material pile 10 gradually decreases and changes during the continuous material feeding process. Through the retractable conveyor belt, it can be extended and adjusted according to the actual situation of the material pile, and cooperate with the material feeder 9 to smoothly transport the raw materials to the sampling station 2, thereby improving the working range of the material feeder 9, ensuring the efficiency of raw material feeding, and thus improving the stability and continuity of raw material sampling.

[0046] Furthermore, a movable support roller 11 is provided at the bottom of the retractable conveyor belt.

[0047] Specifically, since different raw materials are stored in different locations within the same area, a movable support roller 11 is installed at the bottom of the retractable conveyor belt. This allows the retractable conveyor belt to be flexibly moved to different raw material storage locations via the movable support roller 11. According to actual needs, it is convenient to perform material removal operations on different types and storage locations of materials, greatly enhancing the adaptability of the entire sampling device to different raw material storage layouts. There is no need to equip each storage area with a separate sampling and conveying device, thus improving the versatility and efficiency of the device.

[0048] According to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, it also includes a sampling station platform 12, with sampling station 2 located on top of the sampling station platform 12.

[0049] Specifically, since it also includes a sampling station platform 12, with sampling station 2 located on top of the sampling station platform 12, the arrangement of the sampling station platform 12 achieves layered utilization of space. Placing sampling station 2 on top of the platform makes the layout of the entire sampling device more compact and reasonable. Furthermore, the sampling station 2 has a certain height, allowing the raw materials to be transported by their own weight and through connecting pipes to the transfer belt 3, transfer conveyor belt 4, or sampling trough 5, facilitating the connection between different subsequent processing of the raw materials and improving the efficiency of raw material transfer.

[0050] Furthermore, such as Figure 3 As shown, sampling station 2 is equipped with sampling conveying pipe 13, sample preparation conveying pipe 14 and return material conveying pipe 15 respectively. Sampling conveying pipe 13 is connected to sampling trough 5, sample preparation conveying pipe 14 is connected to the front end of transfer belt 3, and return material conveying pipe 15 is connected to transfer conveyor belt 4.

[0051] Specifically, sampling station 2 is equipped with a sampling conveying pipe 13, a sample preparation conveying pipe 14, and a return material conveying pipe 15. The sampling conveying pipe 13 is connected to the sampling tank 5, the sample preparation conveying pipe 14 is connected to the front end of the transfer belt 3, and the return material conveying pipe 15 is connected to the transfer conveyor belt 4. This allows the raw materials to enter the sampling station 2 and be sampled using a systematic sampling method. The raw materials are moved through the sampling conveying pipe 13 to the sampling tank 5 at certain mass or time intervals to collect samples. This ensures that the samples collected cover as much of the raw materials as possible, more accurately reflecting the quality characteristics of the entire batch of raw materials and providing a more reliable basis for trade settlement. Furthermore, some raw materials are transported to the sample preparation system in a timely and accurate manner through the sample preparation conveying pipe 14 and the transfer belt 3 to test the composition, weight, moisture, and other information of the raw materials and to carry out subsequent sample preparation. At the same time, excess raw materials are transported to the return material yard for storage through the return material conveying pipe 15 and the transfer conveyor belt 4. This eliminates the need to use all raw materials for testing or sample preparation, avoiding resource waste and reducing enterprise production costs.

[0052] It should also be noted that this device is suitable for various types of flotation concentrate products, other ore products, solid particle products, and solid powder products, with a particle size range of 10mm-150mm.

[0053] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
