[0019] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0020] According to Figures 1-5 As shown in the figure, this embodiment proposes a sampling device applied to rice detection, including an insertion tube 1, a connecting tube 2 and a plug 3. The top end of the insertion tube 1 is provided with a connecting tube 2, the top end of the connecting tube 2 is fixedly connected with a plug 3, and the inside of the plug 3 is provided with a plurality of empty slots 15. The bottom end of the insertion tube 1 is fixedly connected with a chassis 4, and an opening and closing mechanism is arranged on the chassis 4. An outlet 16 is arranged inside the chassis 4. The plug 3 drives the insertion tube 1 to be inserted into the bag filled with rice from bottom to top. At this time, the rice in the bag falls into the inside of the insertion tube 1 through the empty slots 15. At this time, the bottom end of the insertion tube 1 is in a closed state and does not leak the rice. After the detection container is placed at the bottom end of the insertion tube 1, the opening at the bottom end of the insertion tube 1 is opened through the opening and closing mechanism, and the rice can leak out from the bottom end of the insertion tube 1. In this way, the amount of rice taken can be controlled, and the waste of rice falling on the ground can be avoided.

[0021] The opening and closing mechanism includes a nylon shaft 6, a gear 7, a first closing plate 8 and a second closing plate 9. The inside of the chassis 4 is symmetrically hinged with gears 7 through the nylon shaft 6. One side of each of the two gears 7 is fixedly connected with a first closing plate 8 and a second closing plate 9 respectively. The outer sides of the two gears 7 are meshed with each other. The first closing plate 8 and the second closing plate 9 cover one side of the outlet 16. The shape of the second closing plate 9 is set as a rectangular block structure. The length of the second closing plate 9 is greater than the diameter of the outlet 16, and the width of the second closing plate 9 is greater than the radius of the outlet 16.

[0022] One side of the chassis 4 is provided with a movable slot 12. One end of a movable handle 11 is fixedly connected to the outer side of one of the gears 7. One end of the movable handle 11 penetrates out of the inside of the movable slot 12. A connecting block is welded to the outer side of the gear 7. The shape of the connecting block is set as a T-shaped structure. One end of the connecting block is welded to one side of the first closing plate 8 or the second closing plate 9.

[0023] Flipping the movable handle 11 can drive one of the gears 7 to rotate. Since the two gears 7 are meshed with each other and are connected to the second closing plate 9, the two second closing plates 9 can be driven to rotate in different directions simultaneously, opening the outlet on the chassis 4. At this time, the rice in the bag flows out through the insertion tube 1. When the detection container is about to be filled with rice, flipping the movable handle 11 back drives the two second closing plates 9 to rotate back through the gears 7, closing the outlet on the chassis 4 and blocking the continuous downward sliding of the rice. The frictional force generated by the nylon shaft 6 causes the movable handle 11 to drive the second closing plate 9 to rotate through the nylon shaft 6 and then automatically lock in position.

[0024] On one side of the chassis 4 away from the movable handle 11, a fixed handle 5 is fixedly connected. The position of the fixed handle 5 is symmetrical to the position when the second closing plate 9 is closed by the movable handle 11. At this time, people can hold the movable handle 11 and the fixed handle 5 to insert the insertion tube 1 into the bag containing rice, making it more convenient to insert the insertion tube 1 into the rice bag.

[0025] The shape of the plug 3 is set as a conical structure. A threaded tube 10 is fixedly connected to the top end of the insertion tube 1. The top end of the insertion tube 1 is threadedly connected to the inner wall of the connecting tube 2 through the threaded tube 10. After aligning the plug 3 and the top end of the insertion tube 1 vertically, the connecting tube 2 is tightened on the top end of the insertion tube 1 to install the plug 3 on the top end of the insertion tube 1, and the sharp part at the top of the plug 3 is used to pierce the rice bag.

[0026] A retaining ring 13 is fixedly connected to the outside of the insertion tube 1. An elastic rubber ring 14 is arranged between the two retaining rings 13. The diameter of the elastic rubber ring 14 is smaller than that of the retaining ring 13. After sampling the rice in the bag, the total amount decreases. At this time, the insertion tube 1 can be pulled out of the rice bag, and the punctured opening can be squeezed tightly. The elastic rubber ring 14 outside the insertion tube 1 is used to tie up the squeezed part to prevent the rice from leaking from the opening and causing waste.

[0027] For this rice detection sampling device, flipping the movable handle 11 can drive one of the gears 7 to rotate. Since the two gears 7 are meshed with each other and are connected to the second closing plate 9, the two second closing plates 9 can be driven to rotate in different directions simultaneously, opening the outlet on the chassis 4. At this time, the rice in the bag flows out through the insertion tube 1. When the detection container is about to be filled with rice, flipping the movable handle 11 back drives the two second closing plates 9 to rotate back through the gears 7, closing the outlet on the chassis 4 and blocking the continuous downward sliding of the rice. The frictional force generated by the nylon shaft 6 causes the movable handle 11 to drive the second closing plate 9 to rotate through the nylon shaft 6 and then automatically lock in position.

[0028] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
