[0002] Fertilizer is a substance applied to plants or soil to provide the nutrients required by plants, which can improve soil properties, increase soil fertility level, thereby promoting plant growth, increasing yield and improving quality. In the process of processing and producing fertilizer, it is often necessary to use a sampler to sample and detect the fertilizer in the container. The currently used sampler is mostly a tubular structure, has a feeding slot on the lower end side, and the worker holds the handle when using, and inserts the bottom end of the insertion tube into the material inside, and then the sampler can be taken out after the material enters the feeding slot. The existing sampler has the following disadvantages: the composition of the material at different depths in the container will be different, and the existing sampler can only sample the fertilizer at one depth at a time, which needs to be operated back and forth multiple times, wasting time; secondly, sampling and inspection sometimes only needs to sample the fertilizer at a specific depth (one layer or more layers); therefore, the present application provides a granule sampler for fertilizer production to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.

[0019] Secondly, the utility model is described in detail in combination with the schematic view, and in the detailed description of the utility model embodiments, for the convenience of description, the sectional view of the device structure will be partially enlarged without the general proportion, and the schematic view is only an example, which should not limit the scope of protection of the utility model herein. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0021] Figures 1-4 The whole structure schematic view of the granule sampler for fertilizer production of the utility model is shown, please refer to Figures 1-4 The granule sampler for fertilizer production of the embodiment comprises a top plate 100, a plurality of sampling tubes 200 with different lengths are vertically installed at the bottom of the top plate 100, a material door 210 is hingedly connected to the bottom end of the sampling tube 200, a plurality of electromagnetic valves 300 are arranged on the upper end of the top plate 100 and connected to the upper end of the corresponding sampling tube 200, an air chamber 400 and a small air pump 500 are further arranged on one side of the upper end of the top plate 100, the electromagnetic valve 300 is connected with the air chamber 400 through a pipeline, and the air chamber 400 is connected with the input end of the small air pump 500 through a pipeline.

[0022] The upper end of the small air pump 500 is further provided with a controller 600, which is signal connected between the small air pump 500 and the electromagnetic valve 300. It can be understood that the controller 600 can be used by the user to set and start and stop each driving unit of the sampler, and the integrated control is more convenient to use. The material door 210 has a torsion spring hinge shaft 220 connected to the inner side of the bottom opening of the sampling pipe 200 on one side, and a finger block 230 is further fixed on the bottom side of the material door 210. Here, the material door 210 is in a flat state in a normal state, that is, it forms a blockage to the bottom opening of the sampling pipe 200, and when the sampling pipe 200 is in a suction state, the material door 210 is turned upward, so that the fertilizer particles can enter the inside of the sampling pipe 200. When detecting the material, the user only needs to pinch the finger block 230 and drag the material door 210 outward to turn it over, so that the material can be discharged. The structure is simple and convenient to operate. The electromagnetic valve 300 is connected with the air guide pipe 310 at the opposite end of the sampling pipe 200, and the air chamber 400 is provided with a plurality of air vents 410 connected with the corresponding air guide pipes 310 on one side; the output end of the small air pump 500 is further connected with the air guide pipe 510 between the air chamber 400. In this embodiment, the length of each sampling pipe 200 corresponds to the material layer depth of different depths, and it should be noted that the length and number of the sampling pipe 200 can be set or replaced according to actual needs, which is not limited. Specifically, in actual use, when multiple sampling pipes 200 are vertically inserted into the material, and when the fertilizer at different depths needs to be sampled, the small air pump 500 and the electromagnetic valve 300 corresponding to the layer depth are started by the controller 600. At this time, the air chamber 400 will form a negative pressure under the action of suction, and the sampling pipe 200 will be sucked through the electromagnetic valve 300. Then the material door 210 will be passively turned over to open, so that the fertilizer particles are sucked into the inside of the sampling pipe 200. After completion, the air pump is closed and the electromagnetic pressure relief valve 420 is opened to make the inside of the sampling pipe 200 return to normal pressure. At this time, the material door 210 will automatically close, and finally the sampling pipe 200 and the sampler are pulled out to complete the particle sampling operation. In summary, the granular sampler for fertilizer production effectively solves the problems that the existing sampler can only sample one depth of fertilizer at a time and needs to be operated multiple times, and can uniformly sample the fertilizer at a specific layer depth, thereby effectively improving the work efficiency.

[0023] As a preferred, further, the upper end of the air chamber 400 is further provided with an electromagnetic pressure relief valve 420, and the electromagnetic pressure relief valve 420 is signal connected with the controller 600. It can be understood that after the operation is interrupted or stopped, the air chamber 400 will have residual negative pressure. In order to smoothly switch between different sampling pipes 200, the electromagnetic pressure relief valve 420 is opened after each switching or shutdown, so that external air is introduced into the air chamber 400 and the sampling pipe 200 and returns to normal pressure.

[0024] As preferred, further, the top plate 100 upper end further has a plurality of clamping slots 110 corresponding to the upper end of the sampling pipe 200, and a filter screen 700 is embedded in the inner side of the clamping slot 110. In order to prevent the material particles from entering the electromagnetic valve 300 and the air chamber 400 through the sampling pipe 200 during suction, the filter screen 700 is arranged at the upper end of the sampling pipe 200 to block and filter the material particles. In addition, the electromagnetic valve 300 and the top plate 100 and the sampling pipe 200 can be threadedly connected, buckled, or the like, which is not limited.

[0025] In summary, the granular sampler for fertilizer production of the embodiment, when in use, a plurality of sampling pipes 200 are vertically inserted into the material. When the fertilizer at different depths needs to be sampled, the controller 600 is used to open the small air pump 500 and the electromagnetic valve 300 corresponding to the layer depth. At this time, the air chamber 400 forms a negative pressure under the action of suction, and the sampling pipe 200 is sucked through the electromagnetic valve 300. Then, the material door 210 is passively turned to open, so that the fertilizer particles are sucked into the inside of the sampling pipe 200. After completion, the air pump is closed and the electromagnetic pressure relief valve 420 is opened to return the inside of the sampling pipe 200 to a positive pressure. At this time, the material door 210 is automatically closed. Finally, the sampling pipe 200 and the sampler are pulled out to complete the granular sampling operation.
