[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-3 , the present invention provides a technical solution: a flour sampling device for flour detection, including a first sampling shell 1 and a second sampling shell 2. Two chambers 3 are opened inside the first sampling shell 1 and the second sampling shell 2. Two opening and closing assemblies 4 and two transmission assemblies 5 are provided inside the two chambers 3;

[0029] Among them, the first sampling shell 1 and the second sampling shell 2 can take flour at different depths, which is convenient for flour sampling. When sampling, the flour contacts the transmission assembly 5, and the transmission assembly 5 makes the opening and closing assembly 4 perform opening and closing actions, thereby performing flour sampling, and the flour enters the chamber 3 for storage.

[0030] The opening and closing assembly 4 includes a sliding plate 41, a first fixing frame 42 and a support rod 43. A sliding plate 41 is slidably connected inside the chamber 3. The middle part of the top surface of the sliding plate 41 is fixedly connected with a first fixing frame 42. Two support rods 43 are rotatably connected to the first fixing frame 42. The ends of the two support rods 43 are rotatably connected to two second fixing frames 44. The second fixing frames 44 are fixedly connected to the sides of the two rotating plates 45 close to each other. A plurality of first openings 46 are opened on the peripheries of the first sampling shell 1 and the second sampling shell 2, and the rotating plates 45 are rotatably connected to the first openings 46;

[0031] Among them, during sampling, the sliding plate 41 moves downward. The movement of the sliding plate 41 drives the movement of the first fixing frame 42. The movement of the first fixing frame 42 drives the movement of the support rod 43. One end of the support rod 43 rotates on the first fixing frame 42, and the other end of the support rod 43 rotates on the second fixing frame 44. At the same time, the second fixing frame 44 is pulled inward, and the second fixing frame 44 drives the rotating plate 45 to rotate in the first opening 46. After the rotating plate 45 is opened, the flour enters the chamber 3 from the first opening 46.

[0032] Specifically, as Figures 1-3 shown, the transmission assembly 5 includes a first rack 51, a gear 52 and a second rack 53. The bottom surface of the sliding plate 41 is fixedly connected to the first rack 51. The first rack 51 is meshed with the gear 52. The gear 52 is meshed with two second racks 53. The ends of the second racks 53 are fixedly connected to two sliding blocks 54. A vertical groove 58 is formed on the bottom surface of the chamber 3. One end of a spring 59 is fixedly connected to the bottom surface of the first rack 51, and the other end of the spring 59 is fixedly connected to the bottom surface of the vertical groove 58.

[0033] A plurality of second openings 55 are formed on the circumferences of the first sampling shell 1 and the second sampling shell 2. The sliding blocks 54 are slidably connected to the second openings 55. The sliding blocks 54 are in the shape of arc trapezoidal blocks with a wider top and a narrower bottom.

[0034] A fixing plate 56 is fixedly connected to the bottom of the chamber 3. The upper second rack 53 is slidably connected to the bottom surface of the fixing plate 56, and the lower second rack 53 is slidably connected to the bottom surface of the chamber 3. The gear 52 is fixedly sleeved with a rotating shaft 57. The rotating shaft 57 is rotatably connected to the side wall of the chamber 3. The first rack 51 is slidably connected to the fixing plate 56.

[0035] A plurality of cylindrical rods 8 are slidably connected to the first sampling shell 1 and the second sampling shell 2. The tops of the plurality of cylindrical rods 8 are fixedly connected to a control rod 10. The plurality of cylindrical rods 8 are fixedly connected to two sliding plates 41. One ends of a plurality of tension springs 9 are fixedly connected to the top surface of the two sliding plates 41, and the other ends of the plurality of tension springs 9 are fixedly connected to the top surface of the chamber 3. The plurality of tension springs 9 are movably sleeved on the plurality of cylindrical rods 8. The plurality of cylindrical rods 8 are clamped with two clamping plates 11. The two clamping plates 11 are located on the top surface of the second sampling shell 2.

[0036] A threaded rod 6 is fixedly connected to the bottom surface of the first sampling shell 1. The threaded rod 6 is threadedly connected to a tapered rod 7.

[0037] Among them, the device has different numbers of sampling cases one 1 and sampling cases two 2, which is convenient for dealing with the sampling work of flour at different depths, improving the applicability of the device. When sampling, the staff holds the control rod 10 and inserts the device into the flour. The conical rod 7 contacts the flour to help the sampling cases one 1 and sampling cases two 2 enter the flour better. When the device enters the flour, when sampling is required, the clamping plate 11 is removed from the cylindrical rod 8, and the control rod 10 is pressed. The downward movement of the control rod 10 drives the sliding plate 41 to move downward. The cooperation between the sliding plate 41 and the chamber 3 pulls the tension spring 9 open. At the same time, the sliding block 54 contacts the flour, and the pressure of the flour extrusion causes the sliding block 54 to move inward. The movement of the sliding block 54 drives the second rack 53 to move inward. The movement of the second rack 53 drives the gear 52 to rotate. The rotation of the gear 52 drives the rotating shaft 57 to rotate. The rotation of the gear 52 drives the first rack 51 to move downward. The cooperation between the first rack 51 and the vertical groove 58 compresses the spring 59. The movement of the first rack 51 drives the sliding plate 41 to move downward. The movement of the sliding plate 41 drives the first fixing frame 42 to move. The movement of the first fixing frame 42 drives the support rod 43 to move. One end of the support rod 43 rotates on the first fixing frame 42, and the other end of the support rod 43 rotates on the second fixing frame 44. At the same time, the second fixing frame 44 is pulled inward. The second fixing frame 44 drives the rotating plate 45 to rotate in the first opening 46. After the rotating plate 45 is opened, the flour enters the chamber 3 from the first opening 46. After sampling is completed, the control rod 10 is pulled upward. The pulling force of the tension spring 9 pulls the sliding plate 41 upward. The spring 59 uses its elastic force to restore the first rack 51 to its original position. The cooperation between the first rack 51 and the components restores the other components and the rotating plate 45 to their original positions. The rotating plate 45 closes. Then, the clamping plate 11 is installed on the cylindrical rod 8 again to complete the sampling work. The closing of the rotating plate 45 ensures that the flour is not contaminated and ensures the accuracy of the detection. The flour is stored in the chamber 3. When the flour needs to be taken out, the clamping plate 11 is removed, and the two sliding blocks 54 are pressed. The cooperation of the components opens the rotating plate 45, and the flour can be poured out.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
