Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical fertilizer production, specifically to a sampling device for ammonium sulfate chemical fertilizer production. BACKGROUND

[0002] Ammonium sulfate chemical fertilizer, also known as ammonium sulfate, is a common nitrogen fertilizer. It is also known as fertilizer powder. Chemical fertilizer refers to a fertilizer made by chemical methods that contains one or more nutrients needed for crop growth. After the chemical fertilizer product is processed, it needs to be sampled for inspection.

[0003] The existing sampler cannot seal the chemical fertilizer particles, and cannot delay the detection for a period of time. If the sampling sample is delayed for a period of time for detection or taken back to the laboratory for detection without sealing, the error of the detection result will be large, the detection error will be increased, and the detection accuracy will be affected.

[0004] A sampling device for chemical fertilizer product in chemical fertilizer production is disclosed in Chinese patent No. CN218381763U, which includes a sampling tube body. A sampling groove is formed on the side end surface of the sampling tube body. The sampling groove extends along the axial direction of the sampling tube body. The front end of the sampling tube body is provided with a tapered plug, and the rear end is provided with a handle with a hollow structure. The handle is in communication with the sampling tube body. A sample bag is detachably connected to the rear end of the handle. An adhesive structure is provided at the opening of the sample bag to seal the opening. Silicon anti-slip particles are provided on the surface of the handle.

[0005] The existing technical solution in the above has the following defects: Since the sampling device cannot sample the chemical fertilizer in layers, it is difficult to ensure that the sampled sample can represent the characteristics of the entire chemical fertilizer pile or batch. If the chemical fertilizer has a layered phenomenon, sampling from a certain layer may cause sample deviation, thereby affecting subsequent quality analysis and evaluation.

[0006] Therefore, we propose a sampling device for ammonium sulfate chemical fertilizer production to solve the above problems. Utility model content

[0007] The utility model aims to provide a sampling device for ammonium sulfate chemical fertilizer production to solve the problem of limited sampling range in the background art.

[0008] To achieve the above purpose, the utility model provides the following technical scheme: a sampling device for ammonium sulfate chemical fertilizer production, including a tapered plug and an outer sampling cylinder arranged above the tapered plug. A sampling groove one is formed on the front of the outer sampling cylinder. An annular groove is formed above the outer sampling cylinder. A connecting ring one is fixedly connected to the outer side of the top of the outer sampling cylinder. A handle one is fixedly connected to the two sides of the connecting ring one. A layered sampling mechanism is arranged inside the outer sampling cylinder.

[0009] The layered sampling mechanism comprises a collection unit and a taking-out unit;

[0010] The collection unit comprises a middle-layer sampling cylinder, a sampling groove two, a clamping block, a connecting ring two, a handle two and a connecting outer hole. The middle-layer sampling cylinder is connected to the inside of the outer-layer sampling cylinder. The sampling groove two is opened on the front face of the middle-layer sampling cylinder and corresponds to the position of the sampling groove one. The clamping block is connected to the outside of the middle-layer sampling cylinder. The connecting ring two is fixedly connected to the outside above the middle-layer sampling cylinder. The handle two is fixedly connected to the two sides of the connecting ring two. The connecting outer hole is opened on the two sides of the top of the middle-layer sampling cylinder.

[0011] Preferably, the clamping block is slidingly connected to the annular groove, so that the middle-layer sampling cylinder can stably rotate and position in the outer-layer sampling cylinder. In addition, the sliding connection also provides good sealing to prevent sample leakage during sampling.

[0012] Preferably, the taking-out unit comprises an inner-layer sampling cylinder, a sampling groove three, a connecting inner hole and an internal thread. The inner-layer sampling cylinder is connected to the inside of the middle-layer sampling cylinder. The sampling groove three is opened on the front face of the inner-layer sampling cylinder and corresponds to the position of the sampling groove two. The connecting inner hole is opened on the outside above the inner-layer sampling cylinder. The internal thread is opened on the inside above the inner-layer sampling cylinder. The alignment of the sampling groove three, the sampling groove one and the sampling groove two ensures the accuracy and consistency of sampling.

[0013] Preferably, the inner-layer sampling cylinder and the middle-layer sampling cylinder are connected by a latch. The latch is inserted into the connecting outer hole and the connecting inner hole. The latch connection ensures the stability and firmness between the inner-layer sampling cylinder and the middle-layer sampling cylinder, preventing accidental falling or misplacement during sampling.

[0014] Preferably, the inner-layer sampling cylinder is provided with a separation assembly comprising a sealing cover, a handle, an external thread, a connecting column and a separation plate. The external thread is opened on the outside below the sealing cover. The handle is fixedly connected to the top of the sealing cover. The connecting column is fixedly connected to the bottom of the sealing cover below. The separation plate is fixedly connected to the connecting column. The separation plate in the separation assembly divides the inner-layer sampling cylinder into multiple independent sampling areas. Each area can collect samples of different depths.

[0015] Preferably, the sampling groove one, the sampling groove two and the sampling groove three each have three groups. The separation plate is arranged between the sampling grooves. The design of multiple sampling grooves and separation plates allows users to sample multiple times at different depths and positions, thereby more comprehensively understanding the composition and distribution of fertilizers.

[0016] Preferably, the sealing cover is threadedly connected to the inner sampling cylinder, and the thread connection ensures a tight fit between the sealing cover and the inner sampling cylinder, preventing sample leakage during transportation or storage. In addition, the thread connection also facilitates the user to open and close the sealing cover, facilitating sampling and cleaning.

[0017] Preferably, the outer sampling cylinder, the middle sampling cylinder and the inner sampling cylinder are made of stainless steel material, which has excellent corrosion resistance and strength, can resist the corrosive substances that may exist in chemical fertilizers, and ensures the long-term stability and reliability of the sampling cylinder.
