Technical Field
[0001] The utility model belongs to the technical field of raw grain detection sampling, and particularly relates to a raw grain detection sampler. Background Art
[0002] Raw grain refers to grains that have not been processed or have only been cleaned (such as removing impurities, stones, husks, etc.). These grains are usually from crop harvests and are then directly used for consumption or further processed into other food products. Raw grains include various cereals such as wheat, rice, corn, barley, sorghum, oats, rye, etc., as well as other edible seeds such as soybeans, peas, and lentils.
[0003] In the current process of raw grain detection, the sampler is one of the indispensable tools. However, after sampling with the existing samplers, the raw grain in the sampler is prone to spill during the extraction process, which easily affects the accuracy of sampling. In addition, most of the existing samplers adopt a front-end closed structure. Although it can prevent the raw grain in the sampler from spilling, the structure is relatively complex and the manufacturing cost is relatively high, increasing the overall cost of raw grain detection. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a raw grain detection sampler to solve the problems in the above background art that after sampling with the existing samplers, the raw grain in the sampler is prone to spill during the extraction process, which easily affects the accuracy of sampling. In addition, most of the existing samplers adopt a front-end closed structure. Although it can prevent the raw grain in the sampler from spilling, the structure is relatively complex and the manufacturing cost is relatively high, increasing the overall cost of raw grain detection.
[0005] To achieve the above object, the utility model provides the following technical solution: A raw grain detection sampler, including a sampling tube, one end of the sampling tube is provided with a sampling port, the upper end of the sampling port is rotatably connected with a baffle through a rotating shaft, one end of the baffle is fixedly connected with a rotating plate, the side surface of the sampling tube is provided with a sliding groove, the inside of the sliding groove is slidably connected with a sliding rod, one end of the sliding rod is rotatably connected with the rotating plate through a connecting plate, both side surfaces inside the sliding groove are provided with reset grooves, the inside of the reset groove is fixedly connected with a reset rod, the surface of the reset rod is slidably connected with a reset block, a reset spring is arranged between the reset block and the inner wall of the reset groove, the reset spring is arranged on the surface of the reset rod, and the reset block is fixedly connected to both side surfaces of the reset rod.
[0006] Preferably, the end of the sliding rod far from the connecting plate is fixedly connected with a sliding handle.
[0007] Preferably, a switch structure is installed on the inner side wall surface of the reset groove.

[0012] Compared with the prior art, the present utility model provides a raw grain detection sampler, which has the following beneficial effects:
[0013] 1. By means of structures such as the baffle and the sliding handle provided in the present utility model, when sampling raw grains, the sliding handle is pulled outwards, and the sliding handle drives the sliding rod to slide outwards, thereby pulling the rotating plate outwards through the connecting plate, so that the baffle rotates outwards around the rotating shaft, and the sliding groove of the sampling tube is inserted downwards into the raw grains for sampling. After sampling is completed, the sliding handle is released, and due to the elastic force of the return spring, the sliding rod slides inwards, and the rotating plate is pushed inwards through the connecting plate, so that the baffle rotates around the rotating shaft to be close to one end of the sampling port of the sampling tube, achieving the purpose of closing the sampling tube and preventing the raw grains from falling out of the sampling tube. Subsequently, the sampling tube is pulled out from the raw grains, and the sampled raw grains can be detected, effectively avoiding the problem that the raw grains in the existing sampler are likely to spill during the extraction process after sampling, which is likely to affect the accuracy of sampling. In addition, most of the existing samplers adopt a front-end closed structure, although it can prevent the raw grains in the sampler from spilling, but the structure is relatively complex, the manufacturing cost is relatively high, and the overall cost of raw grain detection is increased;
[0014] 2. By means of the indicator light and the switch structure provided in the present utility model, when sampling, the sliding rod slides outwards, driving the reset block to slide away from the switch structure. At this time, the indicator light is on, indicating that sampling is in progress. When the sliding handle is released after sampling is completed, the elastic force of the return spring drives the reset block to slide towards the switch structure. When the baffle closes one end of the sampling port of the sampling tube, the reset block touches the switch structure, and the switch structure is triggered to control the indicator light to go out, representing that sampling is completed, making the whole sampler more convenient to use;
[0015] 3. By means of the observation port provided in the present utility model, it is convenient to directly observe the amount of raw grains inside the sampling tube through the observation port. By means of the fixed handle provided, it is convenient to hold the sampling tube to sample the raw grains. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-6, the present utility model provides a technical solution: a raw grain detection sampler, including a sampling tube 1. One end of the sampling tube 1 is provided with a sampling port. The upper end of the sampling port is rotatably connected with a baffle 5 through a rotating shaft 4. One end of the baffle 5 is fixedly connected with a rotating plate 6. A sliding groove 8 is provided on the side surface of the sampling tube 1. A sliding rod 9 is slidably connected inside the sliding groove 8. One end of the sliding rod 9 is rotatably connected with the rotating plate 6 through a connecting plate 7. Both side surfaces inside the sliding groove 8 are provided with reset grooves 11. A reset rod 12 is fixedly connected inside the reset groove 11. A reset block 13 is slidably connected on the surface of the reset rod 12. A reset spring 14 is arranged between the reset block 13 and the inner wall of the reset groove 11. The reset spring 14 is arranged on the surface of the reset rod 12. The reset block 13 is fixedly connected to both side surfaces of the reset rod 12. By means of structures such as the baffle 5 and the sliding handle 10 provided, when sampling the raw grain, pull the sliding handle 10 outwards. The sliding handle 10 drives the sliding rod 9 to slide outwards, thereby pulling the rotating plate 6 outwards through the connecting plate 7, making the baffle 5 rotate outwards around the rotating shaft 4, inserting the sliding groove 8 of the sampling tube 1 downwards into the raw grain for sampling. After sampling, release the sliding handle 10. Due to the elastic force of the reset spring 14, the sliding rod 9 slides inwards, pushes the rotating plate 6 inwards through the connecting plate 7, and makes the baffle 5 rotate around the rotating shaft 4 to closely adhere to one end of the sampling port of the sampling tube 1, achieving the purpose of closing the sampling tube 1 and preventing the raw grain from falling out of the sampling tube 1. Then, pull out the sampling tube 1 from the raw grain to detect the sampled raw grain, effectively avoiding the problem that the raw grain in the existing sampler is likely to spill during the extraction process after sampling, which is likely to affect the accuracy of sampling. In addition, most of the existing samplers adopt a front-end closed structure. Although it can prevent the raw grain in the sampler from spilling, the structure is relatively complex, the manufacturing cost is relatively high, and the overall cost of raw grain detection is increased.
[0026] In the present utility model, preferably, one end of the sliding rod 9 far from the connecting plate 7 is fixedly connected with a sliding handle 10.
[0027] In the present utility model, preferably, a switch structure 15 is installed on the inner side wall surface of the reset groove 11.
[0028] In the present utility model, preferably, an indicator light 16 is installed on the surface of the sampling tube 1 far from the sampling port.
[0029] In the present utility model, preferably, the indicator light 16 is electrically connected to the power supply through the switch structure 15. By providing the indicator light 16 and the switch structure 15, when sampling, the sliding rod 9 slides outwards, driving the reset block 13 to slide away from the switch structure 15. At this time, the indicator light 16 lights up, indicating that sampling is in progress. After sampling is completed and the sliding handle 10 is released, the elastic force of the reset spring 14 drives the reset block 13 to slide towards the switch structure 15. When the baffle 5 closes one end of the sampling port of the sampling tube 1, the reset block 13 touches the switch structure 15, and the switch structure 15 is triggered to control the indicator light 16 to go out, representing that sampling is completed, making the whole sampler more convenient to use.
[0030] In the present utility model, preferably, an observation port 3 is provided on the side surface of the sampling tube 1, and a transparent glass is installed inside the observation port 3. By providing the observation port 3, it is convenient to directly observe the amount of raw grain inside the sampling tube 1 through the observation port 3.
[0031] In the present utility model, preferably, a fixed handle 2 is fixedly connected to one end of the sampling tube 1 away from the sampling port. By providing the fixed handle 2, it is convenient to hold the sampling tube 1 to sample the raw grain.
[0032] The working principle and usage process of the present utility model: When in use, first insert the sampling tube 1 into the raw grain. Before insertion, ensure that the sliding groove 8 faces downwards. Then pull the sliding handle 10 to pull the connecting plate 7 to pull the rotating plate 6 outwards, and the baffle 5 rotates around the rotating shaft 4, so that the baffle 5 moves away from the sampling port, and the sampling port is opened to insert into the raw grain for sampling. After sampling is completed, release the sliding handle 10, and the elastic force of the reset spring 14 makes the sliding rod 9 slide inwards. The connecting plate 7 pushes the rotating plate 6 in, and the baffle 5 closely adheres to one end of the sampling port of the sampling tube 1 to close the sampling tube 1 to prevent the raw grain from falling out of the sampling tube 1. The indicator light 16 lights up indicating that sampling is in progress and goes out after sampling is completed. The amount of raw grain inside the sampling tube 1 can be observed through the observation port 3 and the transparent glass. The fixed handle 2 is convenient for holding the sampling tube 1 for sampling. After sampling is completed, pull the sampling tube 1 out of the raw grain and test the sampled raw grain. This sampler avoids the spillage of raw grain during sampling, improves accuracy, has a simple structure, low cost, and is convenient to use.
[0033] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
