Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer sampling, in particular to an agricultural fertilizer sampler. Background Art

[0002] Fertilizer sampling is primarily intended to ensure the quality of fertilizer products, prevent counterfeit and substandard products from entering the market, and protect the rights and interests of farmers and consumers. Fertilizer quality inspection departments at all levels have increased their efforts in random inspections to ensure that all indicators of fertilizer products meet national standards and prevent substandard products from negatively impacting crop growth and the soil environment. This is also intended to ensure that the quality of fertilizer products meets relevant standards and regulations, protect the rights and interests of farmers, and prevent substandard products from entering the market. Sampling inspections allow for the timely detection and resolution of substandard products, preventing their negative impact on agricultural production. During the sampling process, sampling personnel and inspected items are determined using a "double random" method, and the sampling process is recorded through photography or video to ensure fairness and transparency.

[0003] The Chinese authorized publication number is CN 213255718 U. A fertilizer sampler filters out smaller particles in fertilizer through a first sieve in a first sampling section, and conveys the preliminarily filtered fertilizer to a second sampling section via a rotating shaft and a telescopic cylinder. The second sampling section is provided with an inclined second sieve, which filters fertilizer with larger particles and passes the filtered fertilizer onto a conveyor belt via an inclined plate. Fertilizer with standard particle size is then filtered into a sampling box, achieving automatic sampling and capable of sampling fertilizer for each time period.

[0004] However, this patent still has certain shortcomings when used. When fertilizers are produced, it is necessary to sample and test the fertilizer particles. The current sampling method is generally that staff use a sampling device to manually sample the fertilizer particles. When multiple samples need to be taken, it takes a lot of manpower and material resources, and it will also affect the sampling efficiency. In addition, the existing sampling device generally has only one storage box. After a sample is taken, the sample in the storage box needs to be poured out before the next sampling. When multiple samples need to be taken, the collected fertilizer needs to be repeatedly poured out, which is very time-consuming and inefficient. Utility Model Content

[0016] 1.

When the feed port and the discharge pipe at the top of the storage box are aligned during the rotation, the rotation is stopped, and the fertilizer sample can fall from the discharge pipe into the storage box for storage. When the sampling of one group of samples is completed, the adjusting knob is turned to align the other feed port and the discharge pipe, and then the next sampling is carried out. While ensuring the sampling quality, the cost is reduced to the maximum extent and the efficiency is improved, and the reliability and accuracy of the sampling results are also improved.

[0027] Among them, by setting up the sampling component 1, the sampling process can be automatically completed, which greatly reduces the labor intensity of the staff and improves work efficiency. When sampling is required, the switch of the drive motor 103 is turned on first, and then the sampling tube 101 is inserted into the fertilizer sample. The drive motor 103 drives the rotating rod 105 to rotate, so that the fertilizer particles pass through the spiral part 106 into the sampling tube 101, and then fall down from the discharge pipe 107. When the sampling tube 101 needs to be cleaned, it is only necessary to twist the back cover 102 to separate it. The split design of the sampling tube 101 and the back cover 102 facilitates the cleaning of the interior of the sampling component 1.

When the sampling is completed, the fertilizer sample falls from the discharge pipe 107, and the rotating shaft 7 is adjusted by the adjusting button 8. The rotating shaft 7 is connected by the limit block and the limit cylinder 507. Therefore, when the adjusting button 8 drives the rotating shaft 7 to rotate, the rotating structure composed of the placement plate 505, the partition plate 506 and the limit cylinder 507 also rotates with the rotating shaft 7, thereby driving the storage box 508 to rotate.
