Description

Technical Field

[0001] This utility model relates to the field of rice production technology, specifically a sampling device for rice production. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing. Rice is a staple food for people in most parts of China. During the storage of rice, it may separate into layers due to changes in temperature, humidity, and pressure. The quality of the top, middle, and bottom layers of rice may differ significantly, requiring sampling of rice from different depths.

[0003] Chinese Utility Model Patent Application No. 202421648043.6 discloses a sampling device for rice detection. The utility model describes that "turning the movable handle can drive one of the gears to rotate. Since the two gears mesh with each other and are connected to the second sealing plate, they can drive the two second sealing plates to rotate simultaneously in different directions, opening the outlet on the base. At this time, the rice in the bag flows out through the tube. When the detection container is full, turning the movable handle back will drive the two second sealing plates to rotate back through the gears, closing the outlet on the base and preventing the rice from continuing to slide down. The friction generated by the nylon shaft will cause the movable handle to automatically lock its position after driving the second sealing plate to rotate through the nylon shaft, preventing the rice from falling to the ground and being wasted."

[0004] The sampling device used for rice testing involves inserting a plug into a bag of rice. The rice enters the tube through an empty slot and is then sampled by opening the outlet. However, this method not only damages the rice bag but also makes it inconvenient to sample rice at different depths simultaneously, thus affecting the sampling effect. Therefore, an improved sampling device for rice production is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for rice production, comprising a sampling tube, a drill bit fixedly installed at the bottom of the sampling tube, a top plate fixedly installed at the top of the sampling tube, a sample storage tube slidably installed inside the sampling tube, a partition plate fixedly installed inside the sample storage tube, sampling holes being provided inside both the sampling tube and the sample storage tube, and a positioning mechanism being connected to the top of the sample storage tube; Furthermore, the positioning mechanism includes a chamber body, which is fixedly connected to the top of the sample storage tube. A crossbar is fixedly installed inside the chamber body, and a baffle is fixedly installed in the center of the outside of the crossbar. Two springs and two sleeves are sleeved on the outside of the crossbar. The two springs are respectively located between the baffle and the two sleeves.

A positioning rod that extends into the sample tube is fixedly installed on the outside of each of the two movable rods. A movable block is fixedly installed on the top of each of the two movable rods.

[0007] Furthermore, both sleeves have through holes inside, and both through holes are matched with the crossbar.

[0008] Furthermore, the top of the chamber has two movable holes, each of which is matched with two movable rods.

[0009] Furthermore, the sample storage tube has four positioning grooves inside, and each of the four positioning grooves matches a positioning rod.

[0010] Furthermore, each of the two movable blocks has a groove on its top, and the opposite side of each groove is arc-shaped.

[0011] Furthermore, an annular plate extending into the sampling tube is fixedly installed on the outside of the sample storage tube, and an annular groove matching the annular plate is formed on the inner side wall of the sampling tube.

[0012] Furthermore, there are multiple partitions and multiple sampling holes, and the multiple sampling holes are divided into multiple groups, with the number of groups of sampling holes being one more than the number of partitions.

[0013] Furthermore, there are two partitions and three sampling holes, with each of the three sampling holes divided into three groups, and the two partitions located between the three groups of sampling holes.

[0014] Furthermore, there are two partitions and six sampling holes. The six sampling holes are divided into three groups, with two sampling holes in each group symmetrically distributed. The two partitions are located between the three groups of sampling holes.

Then, the positioning mechanism is used to release the sample storage tube from its position, and the positioning mechanism and sample storage tube are rotated 90° to reposition the sample storage tube. The sampling tube then removes its obstruction from the sample storage tube. Rice at different depths enters the sample storage tube through sampling holes of different depths. The partition then blocks the rice at different depths. The positioning mechanism is then used again to release the sample storage tube from its position, and the positioning mechanism and sample storage tube are rotated 90° to reposition the sample storage tube.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment of a sampling device for rice production includes a sampling tube 1, a drill bit 2 fixedly installed at the bottom of the sampling tube 1, a top plate 3 fixedly installed at the top of the sampling tube 1, a storage tube 4 slidably installed inside the sampling tube 1, an annular plate extending into the sampling tube 1 fixedly installed outside the storage tube 4, an annular groove matching the annular plate being opened on the inner side wall of the sampling tube 1, a partition 5 fixedly installed inside the storage tube 4, sampling holes being opened inside both the sampling tube 1 and the storage tube 4, with multiple partitions 5 and multiple sampling holes, each of which is divided into multiple groups, the number of groups of sampling holes being one more than the number of partitions 5, and a positioning mechanism 6 connected to the top of the storage tube 4.

[0021] Specifically, the staff first inserts the drill bit 2 and sampling tube 1 downwards into the rice at the appropriate position. Then, the positioning mechanism 6 is used to release the positioning of the storage tube 4, and the positioning mechanism 6 and the storage tube 4 are rotated 90° to position the storage tube 4. The sampling tube 1 then removes the obstruction from the storage tube 4. Rice at different depths enters the storage tube 4 through sampling holes of different depths. The partition 5 blocks the rice at different depths. Then, the positioning mechanism 6 is used again to release the positioning of the storage tube 4, and the positioning mechanism 6 and the storage tube 4 are rotated 90° to position the storage tube 4. The sampling tube 1 then blocks the storage tube 4. Finally, the drill bit 2 and sampling tube 1 are removed from the rice, which facilitates simultaneous sampling of rice at different depths and improves the sampling effect.

[0022] Please see Figure 5-6 In this embodiment, the positioning mechanism 6 includes a chamber 61, which is fixedly connected to the top of the sample storage tube 4. A crossbar 62 is fixedly installed inside the chamber 61, and a baffle 63 is fixedly installed in the center of the outside of the crossbar 62. Two springs 64 and two sleeves 65 are sleeved on the outside of the crossbar 62. The two springs 64 are located between the baffle 63 and the two sleeves 65, respectively. Both sleeves 65 have through holes inside, and both through holes match the crossbar 62. The top of both sleeves 65 is fixedly installed with a through hole extending into the chamber 61. The top of the sample tube 1 has two movable holes, which are matched with the two movable rods 66. The two movable rods 66 are fixedly installed with positioning rods 67 extending into the sample tube 1. The sample tube 4 has four positioning grooves inside. The four positioning grooves are evenly distributed in a ring and are matched with the positioning rods 67. The top of the two movable rods 66 is fixedly installed with movable blocks 68. The top of the two movable blocks 68 is provided with grooves. The opposite side of the two grooves is arc-shaped.

[0023] Specifically, by grasping the grooves of the two moving blocks 68, the two moving blocks 68 are moved relative to each other. The two moving blocks 68 drive the two moving rods 66, the two positioning rods 67, and the two sleeves 65 to move relative to each other. The two springs 64 are compressed and deformed until the two positioning rods 67 move out of the two positioning slots, which can release the positioning of the sample storage tube 4. By releasing the two moving blocks 68, the two springs 64 return to their deformation and drive the two sleeves 65, the two moving rods 66, and the two positioning rods 67 to move in opposite directions until the two positioning rods 67 are inserted into the two positioning slots, which can position the sample storage tube 4. When the positioning rods 67 are inserted into the two positioning slots, the sampling holes inside the sampling tube 1 and the sampling holes inside the sample storage tube 4 coincide, which can sample the rice. When the positioning rods 67 are inserted into the other two positioning slots, the sampling tube 1 blocks the sampling holes inside the sample storage tube 4, which can block the rice.

[0024] Example 1 In this embodiment, there are two partitions 5 and three sampling holes. The three sampling holes are divided into three groups, and the two partitions 5 are located between the three groups of sampling holes.

[0025] Specifically, the two partitions 5 divide the sample tube 4 into three sample storage areas, and the rice enters the three sample storage areas through the three sampling holes respectively.

[0026] Example 2 In this embodiment, there are two partitions 5 and six sampling holes. The six sampling holes are divided into three groups, with two sampling holes in each group symmetrically distributed. The two partitions 5 are located between the three groups of sampling holes.

[0027] Specifically, the two partitions 5 divide the sample tube 4 into three sample storage areas, and the rice enters the three sample storage areas through six sampling holes.

[0028] Example 3 In this embodiment, there are three partitions 5 and eight sampling holes. The eight sampling holes are divided into four groups, with two sampling holes in each group symmetrically distributed. The four partitions 5 are located between the four groups of sampling holes.

[0029] Specifically, the three partitions 5 divide the sample tube 4 into four sample storage areas, and the rice enters the four sample storage areas through eight sampling holes.

[0030] Compared with Examples 1 and 2, Example 3 increases the number of partitions 5 to increase the sample storage area, which facilitates simultaneous sampling of rice at different depths. Increasing the number of sampling holes increases sampling efficiency and facilitates rapid sampling.

[0031] The working principle of the above embodiments is as follows: The staff first inserts drill bit 2 and sampling tube 1 downwards into the appropriate position in the rice. Then, they hold the grooves of two moving blocks 68 and move them relative to each other. The two moving blocks 68 drive the two moving rods 66, two positioning rods 67, and two sleeves 65 to move relative to each other. The two springs 64 are compressed and deformed until the two positioning rods 67 move out of the two positioning grooves. This releases the positioning of the storage tube 4. Then, the silo body 61 and the storage tube 4 are rotated 90°. The two moving blocks 68 are released, and the two springs 64 return to their original deformation, causing the two sleeves 65, two moving rods 66, and two positioning rods 67 to move in opposite directions until the two positioning rods 67 are inserted into the two positioning grooves. This positions the storage tube 4, making the sampling holes inside the sampling tube 1 and the storage tube 4 coincide. Rice at different depths enters the storage tube 4 through sampling holes of different depths. The partition 5... By isolating rice at different depths, the grooves of two moving blocks 68 are grasped and moved relative to each other. The two moving blocks 68 drive the two moving rods 66, the two positioning rods 67, and the two sleeves 65 to move relative to each other. The two springs 64 are compressed and deformed until the two positioning rods 67 move out of the two positioning grooves. The sampling tube 4 can be released from its position. The chamber body 61 and the sampling tube 4 are rotated 90° and the two moving blocks 68 are released. The two springs 64 recover their deformation and drive the two sleeves 65, the two moving rods 66, and the two positioning rods 67 to move in opposite directions until the two positioning rods 67 are inserted into the two positioning grooves. The sampling tube 4 can be positioned. The sampling tube 1 blocks the sampling hole inside the sampling tube 4, which can block the rice. Finally, the drill bit 2 and the sampling tube 1 are removed from the rice, which facilitates simultaneous sampling of rice at different depths and improves the sampling effect.
