[0002] Rice, also known as paddy rice, refers to rice processed from paddy through cleaning, hulling, milling, and finishing. It is a staple food for people in most parts of China and contains a relatively high amount of carbohydrates, protein, fat, and abundant B vitamins. During rice processing, it is usually necessary to sample and test the produced rice, recording the test results. Quantitative sampling devices for rice testing are specialized equipment used to accurately, quantitatively, and representatively obtain test samples from batches of rice, based on standards such as GB / T 5491.

[0003] However, the amount of rice required to test different data of rice varies. If the amount taken is insufficient, it may affect the test results, while taking too much rice will result in waste. Existing methods require changing different sampling devices or taking multiple samples through the sampling device depending on the amount, which is cumbersome and affects the testing efficiency.

[0025] Please see Figures 1-3 This utility model provides a technical solution: a quantitative sampling device for rice detection, comprising:

[0026] Rice storage tank 1, feeding hopper 3 is fixedly installed at the bottom of rice storage tank 1, feeding pipe 31 is fixedly connected to the bottom end of feeding hopper 3, and valve 32 is installed on feeding pipe 31;

[0027] Install box 2 and fix it to rice storage tank 1;

[0028] The metering cylinder 4 is movably installed in the mounting box 2. The top of the metering cylinder 4 has a feed inlet. The metering cylinder 4 is connected to the discharge pipe 31 through the feed inlet. The metering cylinder 4 is equipped with a metering control component for changing the volume of the metering cylinder 4.

[0029] The quantitative control component includes a quantitative plate 41, which is movably installed inside a quantitative cylinder 4. A material inlet 42 is provided at the center of the quantitative plate 41. An annular guide platform 43 is provided above the quantitative plate 41. A material level sensor 44 is provided at the bottom of the quantitative plate 41. A bottom plate 45 is hinged to the bottom of the quantitative cylinder 4.

[0030] The discharge hopper 7 has an opening at the bottom of the mounting box 2, and the discharge hopper 7 is fixedly installed at the bottom of the mounting box 2 located at the opening.

[0031] A rice storage tank 1 is installed to store rice. A hopper 3 and a discharge pipe 31 are provided to discharge rice from the storage tank 1 through the discharge pipe 31. A valve 32 is provided to control the discharge rate and shut off the discharge pipe 31. A metering cylinder 4 is installed to sample rice quantitatively. A feed inlet allows rice to enter the metering cylinder 4, and a discharge port 42 allows rice to fall to the bottom of the metering cylinder 4. A metering plate 41 is provided; its raising and lowering changes the volume of the metering cylinder 4, facilitating sampling of different quantities of rice. The rice is guided by an annular guide platform 43 to flow to the feed inlet 42. A level sensor 44 is installed, and both the level sensor 44 and the valve 32 are electrically connected to the control system. When the rice in the metering cylinder 4 approaches the metering plate 41, the level sensor 44 sends a signal to the control system, thereby controlling the valve 32 to close and stop the rice from continuing to enter the metering cylinder 4. The bottom plate 45 is hinged. When the metering cylinder 4 moves to the opening, the bottom plate 45 opens directly under the weight of the rice in the metering cylinder 4, allowing the rice in the metering cylinder 4 to enter the discharge hopper 7 through the opening, thus completing the quantitative sampling and feeding of rice.

[0032] Furthermore, a pair of mounting plates 5 are movably installed inside the mounting box 2, and the metering cylinder 4 is fixedly installed between the pair of mounting plates 5. A pair of first gears 51 are rotatably installed between the pair of mounting plates 5. Tooth plates 52 that mesh with the pair of first gears 51 are movably installed on the pair of mounting plates 5. A first permanent magnet 53 is fixedly installed on the pair of tooth plates 52. Second permanent magnets 54 that attract the first permanent magnets 53 are fixedly arranged on both sides of the metering plate 41.

[0033] A pair of mounting plates 5 are installed, and a first gear 51 can be installed between the mounting plates 5. With the first gear 51 installed, the pair of first gears 51 rotate, and the gears mesh with the toothed plate 52, which can drive the toothed plate 52 to rise and fall. A first permanent magnet 53 is set on the toothed plate 52, and a second permanent magnet 54 is set on both sides of the metering plate 41. The first permanent magnet 53 and the second permanent magnet 54 attract each other, and the toothed plate 52 can drive the metering plate 41 to rise and fall.

[0034] Furthermore, a pair of guide rods 55 are fixedly installed inside the metering cylinder 4, and the metering plate 41 is slidably connected to the pair of guide rods 55.

[0035] By providing guide rods 55, it can be ensured that the metering plate 41 does not shift during the lifting and lowering process and always remains vertical.

[0036] Furthermore, a pair of first gears 51 are rotatably mounted between a pair of mounting plates 5 via rotating shafts, and the pair of rotating shafts are connected by a gear transmission assembly 9.

[0037] By providing a gear transmission assembly 9, a pair of first gears 51 can be driven to rotate synchronously in opposite directions, so as to drive a pair of toothed plates 52 to rise and fall simultaneously.

[0038] Furthermore, the gear transmission assembly 9 includes a second gear 91, and there is a pair of second gears 91. One end of each pair of rotating shafts passes through a side mounting plate 5 and the second gear 91 is fixedly connected to the rotating shaft. A pair of meshing third gears 92 are rotatably mounted on the side mounting plate 5, and the pair of third gears 92 mesh with the pair of second gears 91 respectively.

[0039] With the second gear 91 provided, the motor 6 drives a rotating shaft and the second gear 91 to rotate. The second gear 91 meshes with a third gear 92, driving the third gear 92 to rotate. The third gear 92 meshes with another third gear 92, driving the other third gear 92 to rotate. The other third gear 92 meshes with another second gear 91, driving the other second gear 91 to rotate. Thus, through the meshing of the gear sets, a pair of rotating shafts and a pair of first gears 51 can achieve synchronous opposite rotation.

[0040] Furthermore, a vibrating plate 8 is connected to the base plate 45 by several springs 82, and a vibrating motor 81 is fixedly installed at the bottom center of the vibrating plate 8.

[0041] By incorporating a vibrating plate 8, the vibration of the vibrating plate 8 can spread the rice entering the metering cylinder 4 evenly inside the metering cylinder 4, thereby preventing the rice from piling up inside the metering cylinder 4 and affecting the metering function of the metering cylinder 4.

[0042] Furthermore, a threaded rod 61 is rotatably installed inside the mounting box 2, and a threaded block 62 is screwed onto the threaded rod 61. The threaded block 62 is slidably connected to the mounting box 2. A mounting plate 5 is fixedly connected to the threaded block 62. A transverse guide rod 64 is fixedly installed inside the mounting box 2, and a slider 63 is slidably installed on the transverse guide rod 64. The slider 63 is fixedly connected to another mounting plate 5.

[0043] By installing a threaded rod 61, the starting motor 6 can drive the threaded rod 61 to rotate, thereby driving the threaded block 62 to move, which in turn drives a pair of mounting plates 5 to move. By installing a transverse guide rod 64, a slider 63 is slidably installed on the transverse guide rod 64, so that the threaded block 62 and a pair of mounting plates 5 can be driven to move by the threaded rod 61.

[0044] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0045] The working principle and usage process of this utility model are as follows: During use, the volume of the metering cylinder 4 is pre-set according to the required sampling amount for this test via the quantitative control component. Specifically, the motor 6 drives the gear transmission component 9, causing a pair of first gears 51 to rotate synchronously in opposite directions. The first gears 51 mesh with the toothed plate 52, causing the toothed plate 52 to rise and fall. The toothed plate 52, attracted by a permanent magnet, causes the metering plate 41 to rise and fall vertically along the guide rod 55. Once the height of the metering plate 41 is determined, the effective volume of rice that can be contained in the metering cylinder 4 is fixed. The valve 32 on the discharge pipe 31 is opened via the control system, allowing rice from the rice storage tank 1 to flow out through the discharge hopper 3 and discharge pipe 31. The rice enters from the top inlet of the metering cylinder 4, is guided by the annular guide platform 43, and falls into the lower space of the metering cylinder 4 from the central discharge port 42 of the metering plate 41. The bottom is then activated. The vibration motor 81 drives the vibration plate 8 to vibrate, so that the rice is spread evenly and avoids accumulation, ensuring that the material level is uniform and accurate. When the rice level rises to near the metering plate 41, the material level sensor 44 detects the signal and feeds it back to the control system. The control system immediately closes the valve 32 of the feed pipe 31 to stop the rice feeding and complete the precise metering. The threaded rod 61 inside the mounting box 2 is driven to rotate by the motor 6, which drives the threaded block 62 to move laterally. The threaded block 62 and the slider 63 respectively drive the mounting plates 5 on both sides and the metering cylinder 4 fixed in the middle to move horizontally as a whole. The metering cylinder 4 is moved smoothly to above the opening position at the bottom of the mounting box 2. After the metering cylinder 4 reaches the discharge position, the weight of the rice in the cylinder causes the hinged bottom plate 45 to open automatically. The metered rice falls from the opening of the bottom plate 45 and enters the discharge hopper 7 through the opening of the mounting box 2, completing the quantitative sampling and discharge.

[0046] 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.
