Technical Field

[0001] This application relates to the field of fertilizer testing technology, specifically to a sampling device for fertilizer testing. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers.

[0003] Fertilizer sampling devices require inserting a sampling tube into a fertilizer container to extract fertilizer samples. However, when using the sampling device, the testing personnel need to use the sampling device multiple times to take samples, and it is not possible to continuously extract multiple samples at once, which makes the sampling device inconvenient to use.

[0004] Therefore, there is an urgent need for a sampling device for fertilizer testing to solve the problem that sampling devices are inconvenient for extracting multiple samples at once. Utility Model Content

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-4 A sampling device for fertilizer testing includes a support plate 1 and a fixed frame 2 installed on the top of the support plate 1. The fixed frame 2 and the support plate 1 are fixed by bolts. An adjustment mechanism is provided on the outside of the support plate 1, and a sampling mechanism is provided at the bottom of the fixed frame 2.

[0024] Through the above technical solution, the support plate 1 supports the fixing frame 2, the fixing frame 2 supports the sampling mechanism at the bottom, and the sampling mechanism extracts fertilizer samples from inside the fertilizer tank.

[0025] Specifically, the sampling mechanism includes a drive motor 111, a connecting rod 112, a gear 113, a gear 2 114, a spiral rod 115, and a support cylinder 116. The drive motor 111 is located at the top center of the fixed frame 2. One end of the connecting rod 112 is fixedly connected to the output end of the drive motor 111, and the other end of the connecting rod 112 is rotatably connected to the top center of the support plate 1. The gear 113 is fixedly connected to the outer surface of the connecting rod 112, and the gear 2 114 is fixedly connected to the outer surface of the spiral rod 115. The gear 113 meshes with three sets of gears 2 114. The support cylinder 116 is fixedly connected to the inner side of the support plate 1. The spiral rod 115 is located inside the support cylinder 116, and the top of the spiral rod 115 is rotatably connected to the bottom of the fixed frame 2. A slot is provided at the top of the support plate 1 at the position corresponding to the discharge groove of the support cylinder 116, and the storage box 117 is inserted into the slot.

[0026] With the above technical solution, the support cylinder 116 is inserted into the fertilizer tank. When the drive motor 111 starts, it drives the connecting rod 112 to rotate. When the connecting rod 112 rotates, it drives the gear 114 to rotate via the gear 113. When the gear 114 rotates, it drives the screw rod 115 to rotate. When the screw rod 115 rotates, it works with the support cylinder 116 to extract fertilizer samples from the fertilizer tank. The extracted fertilizer samples are discharged from the discharge chute of the support cylinder 116 into the storage box 117 for collection.

[0027] The three sets of spiral rods 115 and support cylinders 116 work together to extract multiple samples at once, making the sampling device more convenient to use.

[0028] The storage box 117 is snapped into the slot, which secures the storage box 117 and prevents it from shifting during sampling.

[0029] Specifically, the adjustment mechanism includes a support sleeve 211, a first support plate 212, a second drive motor 213, a second support plate 214, a connecting sleeve 215, a clamping block 216, a threaded sleeve 221, and a threaded rod 222. The support sleeve 211 is located on the outside of the support plate 1. One end of the first support plate 212 is slidably connected to the inside of the support sleeve 211. The second drive motor 213 is located on the top of the first support plate 212. The second support plate 214 is welded to the other end of the first support plate 212. The connecting sleeve 215 is slidably connected to the bottom of the second support plate 214. The clamping block 216 is welded to the bottom of the connecting sleeve 215. The clamping block 216 is a U-shaped block. One end of the threaded sleeve 221 is coaxially fixedly connected to the output end of the second drive motor 213. The inner wall of the threaded sleeve 221 is machined with internal threads. The other end of the threaded sleeve 221 is threadedly connected to one end of the threaded rod 222. The other end of the threaded rod 222 is fixedly connected to the bottom of the connecting sleeve 215 by bolts.

[0030] Specifically, the top of the support sleeve 211 is threaded with a fastener 219, and the top of the support plate 212 is provided with an insertion hole 220 at the position corresponding to the fastener 219.

[0031] Using the above technical solution, the worker pulls the support plate 212, which slides inside the support sleeve 211, thereby adjusting the position of the support plate 212. The worker then rotates the fastener 219, which is inserted into the socket 220 to fix the position of the support plate 212.

[0032] Specifically, the clamping block 216 is threaded with a fastener 217 on its outer side, and a pressure plate 218 is fixedly connected to one end of the fastener 217.

[0033] With the above technical solution, the clamping block 216 is clamped on the fertilizer barrel. The worker rotates the fastener 217, which drives the pressing plate 218 to press against the outside of the fertilizer barrel, thereby fixing the position of the clamping block 216.

[0034] Start drive motor 213. Drive motor 213 drives threaded sleeve 221 to rotate. When threaded sleeve 221 rotates, it drives threaded rod 222 to move up and down. When threaded rod 222 moves up and down, it drives connecting sleeve 215 to slide on the outside of support plate 214. When connecting sleeve 215 moves up and down, it drives clamping block 216 to move up and down.

[0035] By adjusting the position of the support plate 212 and the height of the clamping block 216, the sampling device can be easily fixed to fertilizer barrels of different sizes, making it convenient to extract fertilizer samples from inside fertilizer barrels of different sizes and making the sampling device more convenient to use.

[0036] In use, by adjusting the position of the support plate 212 and the height of the clamping block 216, the sampling device can be fixed to fertilizer buckets of different sizes. Adjusting the height of the clamping block 216 changes the height of the support plate 1, thereby driving the sampling mechanism to move up and down. When the screw rod 115 rotates, it works with the support cylinder 116 to extract fertilizer samples from the fertilizer bucket. At the same time, by adjusting the height of the support plate 1, the screw rod 115 and the support cylinder 116 can extract samples at different depths. Moreover, the three sets of screw rods 115 and support cylinders 116 can work together to extract multiple samples at once, making the sampling device more convenient to use.

[0037] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
