[0003] In traditional ore sampling, in order to ensure the randomness of sampling, the number of samples taken each time is much larger than the amount needed for testing. This not only causes waste and inconvenience, but also fails to guarantee the randomness of sampling even with increased sample size, thus reducing the effectiveness of testing. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automated sampling and sample preparation system for bulk cargo in ports. Through multiple sampling and reduction, it can ensure the randomness of the final sample taken, improve the inspection effect, and reduce the amount of final sample taken, thus reducing waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated sampling and sample preparation system for bulk cargo in ports, including a primary sampling machine, which is used to periodically collect ore from the conveyor belt that transports ore in the port.

[0006] A secondary sampling machine is used to reduce the ore collected by the primary mining machine and to perform secondary sampling from the reduced ore.

[0007] A tertiary sampler is used to further reduce the ore sampled by the secondary sampler and to perform a third sampling on the reduced ore.

[0008] And a sample collector for collecting the ore sampled by the tertiary sampler.

[0009] The present invention is further configured such that the secondary sampler and the tertiary sampler are composed of a reduction unit.

[0010] The present invention is further configured such that: the secondary sampling machine performs ore reduction sampling according to sampling requirements using a reduction device;

[0012] The present invention is further configured to include a waste material conveyor belt, a secondary sampler and a tertiary sampler, and the ore remaining after sampling is conveyed to the waste material conveyor belt and then conveyed to the ore conveyor belt at the port.

[0013] The present invention is further configured such that a feeding belt conveyor for transporting ore is provided between the primary mining machine and the secondary sampling machine, and between the secondary sampling machine and the tertiary sampling machine.

[0014] The present invention is further configured to include a mixer, which is disposed between the secondary sampler and the tertiary sampler. The mixer mixes the ore sampled by the secondary sampler and then transports it to the tertiary sampler.

[0015] The present invention is further configured such that the sample collector is a multi-station sample collector.

[0016] The present invention is further configured to include a particle size sampler, which is used to sample the ore remaining after sampling by the three-stage sampler and select ore that meets the particle size requirements.

[0017] The present invention is further configured to include a sampling reduction machine, which is used to reduce the sampling time of the three sampling machines and deliver the final sample to the sample collector.

[0018] And a crushing and reducing integrated machine, which is used to crush and reduce the ore remaining after sampling by the reducing machine.

Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] Example 1: An automated sampling and sample preparation system for bulk cargo in ports, see attached document. Figure 1 The system includes a primary mining machine 1, a secondary sampling machine 2, a tertiary sampling machine 3, and a sample collector 4. The primary mining machine 1 is used to periodically collect ore from the conveyor belt transporting ore at the port. The secondary sampling machine 2 is used to reduce the ore collected by the primary mining machine 1 and perform secondary sampling from the reduced ore. The tertiary sampling machine 3 is used to further reduce the ore sampled by the secondary sampling machine 2 and perform a tertiary sampling from the reduced ore. The sample collector 4 is used to collect the ore sampled by the tertiary sampling machine.

[0025] When the primary mining machine 1 is sampling, it samples the entire section of ore conveyed on the conveyor belt, that is, it samples the entire section of ore from top to bottom during the conveying process, so as to ensure the representativeness of the sample. Then, after the secondary sampling machine 2 and the tertiary sampling machine 3 reduce and resample, it ensures that the sampled amount does not far exceed the amount required for inspection and that the sampled ore is sufficiently representative.

[0026] Specifically, the secondary sampler 2 and the tertiary sampler 3 are composed of a reduction unit.

[0027] Specifically, the secondary sampler 2 uses a divider to divide and sample the ore according to the sampling requirements; the tertiary sampler 3 uses a divider to divide and sample the ore according to the sampling requirements.

[0028] Specifically, this embodiment also includes a waste material conveyor belt 5, and the ore sampled by the secondary sampler 2 and the tertiary sampler 3 is transported to the waste material conveyor belt 5 and then transported to the ore conveyor belt at the port.

[0029] By setting up the waste material conveyor belt 5, the ore remaining from the secondary and tertiary sampling can be directly transported to the ore conveyor belt at the port, thus preventing the waste of ore.

[0030] Specifically, a feeding belt conveyor 6 for transporting ore is installed between the primary mining machine 1 and the secondary sampling machine 2, and between the secondary sampling machine 2 and the tertiary sampling machine 3.

[0031] Specifically, this embodiment also includes a mixer 7, which is located between the secondary sampler 2 and the tertiary sampler 3. The mixer 7 mixes the ore sampled by the secondary sampler 2 and then transports it to the tertiary sampler 3.

[0032] By using the mixer 7, the samples from the second sampling can be mixed, ensuring the randomness of the sampling when the third sampling is performed, thereby improving the representativeness of the sampling.

[0033] Specifically, sample collector 4 is configured as a multi-station sample collector 4.

[0034] Specifically, this embodiment also includes a particle size sampler 31, which is used to sample the ore remaining after sampling by the three-stage sampler 3 and select ore that meets the particle size requirements.

[0035] Specifically, this embodiment also includes a sampling and reducing machine 8 and a crushing and reducing integrated machine 9. The sampling and reducing machine 8 is used to reduce the ore sampled by the three-stage sampling machine 3 and transport the final sample to the sample collector 4. The crushing and reducing integrated machine 9 is used to crush and reduce the ore remaining after sampling by the reducing machine.

[0036] Example 2: An automated sampling and sample preparation method for bulk cargo in ports, comprising the following steps:

[0037] S01, a single sampling, is carried out by the primary mining machine 1 on the conveyor belt that transports ore in the port.

[0038] S02, Secondary sampling, the ore collected by the primary mining machine 1 is reduced and sampled according to the sampling requirements by the secondary sampling machine 2;

[0039] S03, mixing, mixing the ore sampled by the secondary sampler 2 using the mixer 7;

[0040] S04, three-stage sampling: the mixed ore is sampled in three stages using a three-stage sampling machine according to the sampling requirements.

[0041] S05, final sampling: the ore sampled by the three-stage sampler 3 is reduced by the sampling reduction machine 8, and the final sample is transported to the sample collector 4.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
