Description

Technical Field

[0001] This utility model relates to the field of grain testing technology, and in particular to a grain testing sampling device. Background Technology

[0002] For a certain period, stored grains are alive; like humans, they breathe. During respiration, they absorb oxygen from the air, oxidizing and decomposing the nutrients inside the grains to produce carbon dioxide, water, and heat, which accumulate in the spaces between the grains. Because grains themselves have poor thermal conductivity, heat is difficult to conduct to the outside of the grain pile and dissipate. Gradually, more and more heat accumulates until the heat and moisture reach a stage suitable for microbial reproduction. At this point, the microorganisms begin to become active, decomposing and absorbing the nutrients in the grain.

[0003] To maintain grain quality and enable people to consume higher-quality grain, it is necessary to sample and test stored grain. Sampling devices are used to sample and inspect the grain in the grain warehouse. When the sampling device is removed from the grain warehouse, the grain enters the device through the sampling hole. The filling of the grain makes it impossible to completely seal the sampling port, which causes the grain to easily fall from the bottom of the sampling hole. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that the sampling port cannot be completely sealed when filled with grain, which makes it easy for the grain to fall from the bottom of the sampling hole. Therefore, this invention provides a grain detection and sampling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a grain testing and sampling device, including a sampling barrel, a pointed tip fixedly connected to the bottom of the sampling barrel, a first fixing block fixedly connected inside the sampling barrel, a pull rod slidably inserted on the first fixing block, a baffle fixedly connected to the bottom of the pull rod, a feed inlet opened on one side of the bottom of the sampling barrel, the baffle cooperating with the feed inlet, the pull rod connected to the inner wall of the sampling barrel through an elastic element, and a storage mechanism fixedly connected to the bottom of the inside of the sampling barrel;

[0007] The storage mechanism includes an elastic band, which is fixedly connected to the inner wall of the sampling bucket, and a round pocket is fixedly connected to the bottom end of the elastic band.

[0008] Preferably, the sampling bucket and the tip are an integral structure.

[0009] Preferably, the elastic element includes a mounting block, which is fixedly connected to the pull rod. The bottom end of the mounting block contacts the upper end of the first fixed block. A spring is fixedly connected to the upper end of the mounting block. A second fixed block is fixedly connected inside the sampling bucket. The pull rod passes through the second fixed block. One end of the spring is fixedly connected to the bottom end of the second fixed block.

[0010] Preferably, handles are fixedly connected to both sides of the upper end of the sampling bucket.

[0011] Preferably, the upper end of the pull rod extends outside the sampling bucket and is fixedly connected to a circular block.

[0012] The grain testing and sampling device proposed in this utility model has the following advantages:

[0013] The baffle moves downwards and squeezes the sampled grain in the round bag. The sampled grain squeezes the round bag, which pulls the elastic band downwards. The elastic band is stretched and extends, causing the round bag containing the grain to move downwards. After the round bag containing the grain moves downwards, there is a gap between it and the bottom of the feed inlet. This allows the bottom of the baffle to return to its original position below the bottom of the feed inlet, completely sealing the feed inlet and preventing the grain in the sampling bucket from falling out of the feed inlet after the sampling bucket is removed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-3 A grain testing and sampling device includes a sampling barrel 1, a pointed tip 2 fixedly connected to the bottom of the sampling barrel 1, the sampling barrel 1 and the pointed tip 2 are an integral structure, a first fixing block 4 is fixedly connected inside the sampling barrel 1, a pull rod 3 is slidably inserted on the first fixing block 4, a baffle 5 is fixedly connected to the bottom of the pull rod 3, a feed inlet 6 is opened on one side of the bottom of the sampling barrel 1, the baffle 5 cooperates with the feed inlet 6, the pull rod 3 is connected to the inner wall of the sampling barrel 1 through an elastic element 7, a storage mechanism 9 is fixedly connected to the bottom of the sampling barrel 1, the upper end of the pull rod 3 extends to the outside of the sampling barrel 1 and is fixedly connected to a circular block 8, and handles 10 are fixedly connected to both sides of the upper end of the sampling barrel 1.

[0021] The storage mechanism 9 includes an elastic band 91, which is fixedly connected to the inner wall of the sampling bucket 1, and a round pocket 92 is fixedly connected to the bottom end of the elastic band 91.

[0022] Work process:

[0023] When sampling grain, hold handle 10. Handle 10 drives sampling bucket 1 to be inserted into grain bin. The bottom of sampling bucket 1 is inserted into grain bin through tip 2, which reduces the resistance encountered by sampling bucket 1 during insertion and makes it easier to insert sampling bucket 1 into grain bin.

[0024] After the sampling bucket 1 is inserted to a certain depth, the pull rod 3 is pulled upward by the circular block 8. The pull rod 3 pulls the baffle 5. After the baffle 5 moves upward, it is misaligned with the feed inlet 6. The feed inlet 6 is opened. The grain passes through the feed inlet 6 and enters the sampling bucket 1, then falls on the round bag 92. At the same time, the pull rod 3 moves upward and squeezes the elastic element 7. The elastic element 7 generates elastic force after being squeezed.

[0025] Release the lever 3 again. Under the elastic force of the elastic element 7, the lever 3 moves downward. The lever 3 moves the baffle 5 downward. After the baffle 5 moves downward, it squeezes the sampled grain on the round bag 92. The sampled grain squeezes the round bag 92, and the round bag 92 pulls the elastic band 91 downward. The elastic band 91 is stretched after being pulled, so that the round bag 92 containing grain moves downward. After the round bag 92 containing grain moves downward, there is a gap between it and the bottom of the feed inlet 6. This allows the bottom of the baffle 5 to be reset and located below the bottom of the feed inlet 6, completely sealing the feed inlet 6 and preventing the grain in the sampling bucket 1 from falling from the feed inlet 6 after the sampling bucket 1 is taken out.

[0026] Example 2: In Example 1, after sampling, it is inconvenient to push the baffle 5 back to its original position using the pull rod 3. (Refer to...) Figure 1As another preferred embodiment of this utility model, the difference from embodiment 1 is that the elastic element 7 includes a mounting block 71, which is fixedly connected to the pull rod 3. The bottom end of the mounting block 71 is in contact with the upper end of the first fixed block 4. A spring 73 is fixedly connected to the upper end of the mounting block 71. A second fixed block 72 is fixedly connected inside the sampling barrel 1. The pull rod 3 passes through the second fixed block 72. One end of the spring 73 is fixedly connected to the bottom end of the second fixed block 72. When the pull rod 3 moves upward, it drives the mounting block 71 to move. After the mounting block 71 moves upward, it squeezes the spring 73. The spring 73 generates elastic force after being compressed. After the sampling is completed, the spring 73 drives the pull rod 3 to move downward and reset under the action of the elastic force of the spring 73, which facilitates the push of the baffle 5 to reset by the pull rod 3.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
