[0002] As a staple food for billions of people worldwide, the quality of rice processing directly affects food safety and nutritional health. During rice processing, multiple indicators such as germ retention rate, broken rice rate, yellow rice rate, disease spot rate, impurity rate, chalkiness rate, and mixed rice rate need to be tested to assess processing precision and quality grade. Therefore, it is necessary to conduct testing and sampling operations on rice during processing. Currently, rice testing relies heavily on manual sampling. However, in actual production, the bulk density of bagged or bulk rice is uneven, and there are significant differences in processing precision, moisture content, and fatty acid value between the rice grains deep inside the bag and those on the surface. Furthermore, the sampling tubes used in the current sampling process have a fixed length and cannot be flexibly adjusted according to different sampling locations, making it difficult to obtain representative samples from the bottom of the rice bag, resulting in sampling deviations.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-10 This utility model provides a technical solution: an adjustable sampling structure for rice processing and testing, including a main rod 1, which is the main body of the sampling structure. The operator can perform sampling operations through the main rod 1. Multiple sampling tubes 6 are detachably connected to the lower side of the main rod 1. The bottom of the lowest sampling tube 6 is connected to a conical plug 16. The conical plug 16 facilitates the insertion of the sampling structure into the rice. The multiple sampling tubes 6 are used to perform sampling operations on rice at different depths after the sampling structure is inserted into the rice. A pair of grip handles 2 are installed on both sides of the main rod 1 to facilitate the operator to hold the sampling structure. The middle part of the main rod 1 is rotatably connected to the drive shaft 3. A rotating handle 4 is fixedly installed on the top of the drive shaft 3. The opening and closing of the movable door 13 can be achieved by rotating the handle 4 in conjunction with the drive shaft 3. The sampling tube 6 is provided with two collection chambers 8, and each of the two collection chambers 8 has a feed inlet 9 on its side wall. The sampling tube 6 is rotatably connected to a driven shaft 10. The driven shafts 10 in two adjacent sampling tubes 6 and the driven shafts 10 and the drive shaft 3 are connected by a detachable coupling. Two movable doors 13 for blocking the feed inlets 9 are fixedly installed on the driven shafts 10 by a connecting bracket 14. After the sampling tube 6 is inserted into the main rod 1, the operator can open and close the movable doors 13 by turning the handle 4 in conjunction with the detachable coupling.

[0017] As an embodiment of the present invention, the detachable coupling includes a cross block 11 fixedly installed on the top of the driven shaft 10, and a cross groove 12 opened at the bottom of the drive shaft 3 and the bottom of the driven shaft 10 and corresponding to the cross block 11. The cross block 11 and the cross groove 12 can be inserted and driven together to facilitate the opening and closing operation of the aforementioned movable door 13.

[0018] In one embodiment of this utility model, a pair of identical guide openings 5 ​​are provided on the lower side of the main rod 1 and the lower side of the sampling tube 6. An annular ring 23, capable of being fitted onto the outside of the drive shaft 3 or the driven shaft 10, is rotatably disposed inside the guide opening 5. A pair of sliding rods 24 are fixedly disposed on the annular ring 23. A first insertion tube 7 is fixedly installed on the top of the sampling tube 6, and a second insertion tube 17 is fixedly installed on the top of the conical plug 16. Both the first and second insertion tubes 7 have a pair of sliding rods 24 at their tops. The L-shaped port 18 has a pair of sliding rods 24 that can slide within the guide port 5 and the L-shaped port 18. After the main rod 1 and multiple sampling tubes 6 have completed the insertion operation, the guide port 5 and the lower side of the L-shaped port 18 coincide. The operator can rotate the pair of sliding rods 24, so that the sliding rods 24 slide inside the guide port 5 and move from one end of the L-shaped port 18 to the other end. With the cooperation of the first insertion tube 7 and the second insertion tube 17, the insertion and locking operation of the main rod 1 and multiple sampling tubes 6 can be completed, increasing the insertion strength between multiple rods.

[0019] As an embodiment of this utility model, an arc-shaped metal ring 21 is fixedly provided inside the guide opening 5. Each of the four corners of the metal ring 21 is provided with an elastic triangular member 22 for limiting the sliding rod 24. The elastic triangular member 22 can limit the sliding rod 24 sliding inside the metal ring 21, thereby achieving the purpose of locking.

[0020] As one embodiment of this utility model, a push block 25 is fixedly installed at the end of a pair of sliding rods 24, which facilitates the operator to push the sliding rods 24 to move.

[0021] As an embodiment of this utility model, a blocking ring 26 is connected to a pair of sliding rods 24. The thickness of the blocking ring 26 is greater than the height of a pair of guide ports 5, which can prevent rice from entering from the guide ports 5 and causing the sampling structure to jam.

[0022] As an embodiment of this utility model, a pair of auxiliary plugs 19 are provided on both the first plug tube 7 and the second plug tube 17. A pair of auxiliary slots 20 corresponding to the auxiliary plugs 19 are provided at the bottom of both the main rod 1 and the sampling tube 6. The auxiliary plugs 19 and the auxiliary slots 20 cooperate to facilitate the operator to align each component when assembling the sampling structure and prevent deviations during insertion.

[0023] As an embodiment of this utility model, an arc-shaped groove 27 is provided on the upper side of the main rod 1, and circular limiting grooves 28 are provided at both ends of the arc-shaped groove 27. A spring rod 29 that can slide along the arc-shaped groove 27 is installed at the front end of the rotating handle 4. A circular limiting block 15 corresponding to the circular limiting groove 28 is fixedly installed at the telescopic end of the spring rod 29. Through the cooperation of the spring rod 29, the circular limiting groove 28 and the circular limiting block 15, the position of the drive shaft 3 and the driven shaft 10 can be locked, thereby preventing the movable door 13 from becoming loose after the sampling structure is inserted into the rice, which would affect the sampling operation.

[0024] Those skilled in the art can connect all electrical components in this case to their compatible power supplies via wires, and appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence are well-known technologies and will not be described in detail here.

[0025] The working principle and usage process of this utility model are as follows: The operator first determines the number of sampling tubes 6 required according to the actual sampling depth, and prepares the corresponding sampling tubes 6 and conical plugs 16. The sampling tubes 6 and conical plugs 16 are inserted into the bottom of the main rod 1 from top to bottom. During the insertion process, the auxiliary plugs 19 on the first insertion tube 7 and the second insertion tube 17 cooperate with the auxiliary slots 20 at the bottom of the main rod 1 and the sampling tube 6 to perform preliminary positioning and alignment to prevent deviation during insertion. After the sampling tube 6 is inserted into the main rod 1, the cross block 11 at the top of the driven shaft 10 inside the sampling tube 6 is inserted into the cross groove 12 at the bottom of the drive shaft 3 to complete the transmission connection between the drive shaft 3 and the driven shaft 10. This allows the operator to control the opening and closing of the movable doors 13 in the two collection chambers 8 by rotating the handle 4. After insertion, a pair of sliding rods 24 will be inserted simultaneously into one end of the L-shaped opening 18 (the sliding rods 24 are also located at one end of the metal ring 21). The operator moves the push block 25 at the end of the sliding rods 24, so that the pair of sliding rods 24 on the annular ring 23 slide inside the metal ring 21 in the guide opening 5. When the sliding rods 24 move to the other end of the L-shaped opening 18 (the sliding rods 24 move to the other end of the metal ring 21 simultaneously), under the elastic force of the elastic triangular piece 22, the sliding rods 24 are locked into the other end of the metal ring 21. The elastic triangular piece 22 completes the locking operation after insertion, increasing the connection strength between the main rod 1, the sampling tube 6 and the conical plug 16. At the same time, the blocking ring 26 can prevent rice from entering from the guide opening 5 and causing jamming. After the above operations are completed, the spring rod 29 at the front end of the rotating handle 4 is slid along the arc groove 27 to the circular limiting groove 28 at one end. The circular limiting block 15 is embedded in the circular limiting groove 28 under the elastic force of the spring rod 29, locking the position of the drive shaft 3 and the driven shaft 10, so that the movable door 13 is in the closed state. The operator then inserts the sampling structure into the rice by holding the handle 2. The conical plug 16 can easily reach the bottom of the rice bag. After reaching the target depth, the operator rotates the handle 4, which drives the driven shaft 10 to rotate through the drive shaft 3. The pair of connecting brackets 14 on the driven shaft 10 drive the movable doors 13 in the two collection chambers 8 to open synchronously, and the spring rod 29 slides along the arc groove 27 to the circular limiting groove 28 at the other end, so that the movable door 13 always remains open. Rice at different depths enters the two collection chambers 8 of each sampling tube 6 through the feed inlet 9, realizing stratified sampling at different depths and avoiding mixing of samples from the deep part of the rice bag with the surface sample. After sampling is completed, the operator rotates the handle 4 in the opposite direction to close the movable door 13, and then the sampling structure can be pulled out. After sampling is completed, reverse the sliding rod 24 to disengage it from the L-shaped opening 18, then disassemble the conical plug 16 and the sampling tube 6 in sequence, open the movable door 13 inside the sampling tube 6, and take out rice samples from different depths for testing and analysis.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
