[0002] In existing rice processing production lines, the rice hulling stage is a crucial step in paddy hulling, and its quality directly affects the subsequent rice milling and grading results. In actual production, to accurately assess the hulling effect, it is typically necessary to take samples from the production line to test the composition ratio of the paddy-brown mixture.
[0003] Firstly, most testing equipment on the market can only test small samples within 50g, so sampling is mostly done on small samples, resulting in unrepresentative test results and large errors. To improve this situation, large-sample testing equipment must be used, combined with our sampling equipment, to collect at least several kilograms of material at a time. However, this requires a sample separation device to ensure that the processed sample is within the testing range of the equipment, 300-500g. Currently, there is no such sample separation device on the market, especially one suitable for separating mixtures of wheat and chrysanthemum. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0028] like Figures 1-7 As shown in the figure, the present invention provides a sampling device for auxiliary hulling section detection in a rice production line, comprising a device housing 17, on which a feeding assembly 1 is provided. The feeding assembly 1 includes a feeding hopper 104, a baffle plate 108 and a cylinder 1010. The baffle plate 108 is fixedly connected to the output end of the cylinder 1010 and is movably connected to the bottom of the feeding hopper 104.
[0029] The device housing 17 is provided with a sample separation component 2, which consists of two sets arranged vertically. The sample separation component 2 is a multi-component material cylinder arranged side by side, with the outlets of adjacent material cylinders arranged in opposite directions. The device housing 17 is provided with a buffer plate 8, which is located between the two sets of sample separation components 2. The device housing 17 is provided with an outlet 11 at the bottom, which is located below the second set of sample separation components 2.
[0030] In this embodiment, the insert plate 108 is driven by the cylinder 1010 to control the opening and closing of the bottom outlet of the feed hopper 104 to achieve quantitative feeding. The device housing 17 is provided with two sets of vertically arranged sample-dividing components 2, and each set of sample-dividing components 2 is composed of multiple parallel material-dividing cylinders. The outlets of the material-dividing cylinders are arranged in staggered directions to disrupt the material flow and achieve multiple graded sampling. The buffer plate 8 is located between the two sets of sample-dividing components 2, which can effectively buffer the impact force of the material and stabilize its landing point. The outlet 11 is located below the lower sample-dividing component 2 to output samples that meet the detection conditions.
[0031] After being released from the feed hopper 104, the material falls downwards by gravity into the first group of sampling components 2 located inside the outer casing 17 of the device. This component consists of multiple parallel distributing cylinders with their outlets facing opposite directions, guiding the material to disperse in different directions during its descent, thus forming primary sampling. Next, the material passes through a buffer plate 8 positioned in the middle at a slightly inclined angle. Its upper surface receives the material after the initial sampling, mitigating the impact and stabilizing the falling path, thereby improving the stability and accuracy of the next stage of sampling. The material then enters the second group of sampling components 2 for further sorting. Similar in structure to the first group, it also consists of parallel distributing cylinders. The selected target material is discharged into the testing equipment through the bottom outlet 11, while unselected material or light impurities are guided to the waste outlet 12 through other bottom outlets, completing the entire sampling process.
[0032] like Figure 1 and Figure 7 As shown, in one embodiment of this utility model, the feeding assembly 1 further includes a support frame 101, a pad 102, a pressure plate 103, a cylinder bracket 105 and a cylinder bracket 106. The support frame 101 is fixedly connected to the device housing 17. The pad 102 is provided on the support frame 101, and the pressure plate 103 is provided on the pad 102. The pressure plate 103 is fixedly connected to the feeding hopper 104. A cylinder bracket 105 and a cylinder bracket 106 are provided on one side of the support frame 101. The cylinder bracket 105 and the cylinder bracket 106 are fixedly connected to the cylinder 1010.
[0033] In this embodiment, the support frame 101 serves as the structural support foundation for the entire feeding system. It is fixed to the upper part of the device housing 17 by bolts or welding and is used to support the overall weight of the feeding hopper 104 and related power mechanisms. The pad 102 is set on the top of the support frame 101 to distribute the force and avoid structural deformation caused by local stress concentration. The pressure plate 103 is close to the upper edge of the feeding hopper 104 to firmly press it onto the pad 102 and prevent the feeding hopper from shaking under long-term operation or feeding impact. Cylinder bracket one 105 and cylinder bracket two 106 are distributed at both ends of the cylinder 1010 and are bolted together to stably fix the cylinder to one side of the support frame 101, so that the cylinder output shaft can accurately drive the insert plate 108 to move horizontally, thereby ensuring accurate and efficient opening and closing of the discharge port.
[0034] like Figure 1 and Figure 7As shown, in one embodiment of the present invention, the feeding assembly 1 further includes an observation window 107 and a small filter plate 109. The observation window 107 is provided on the side of the feeding hopper 104, and the small filter plate 109 is provided inside the feeding hopper 104. The small filter plate 109 is movably connected to the inner wall of the feeding hopper 104.
[0035] In this embodiment, the observation window 107 is located on the side wall of the feed hopper 104 and is made of transparent tempered glass or polycarbonate material. It can withstand material impact and has excellent light transmission performance, allowing operators to easily observe the remaining amount and flow status of material inside the feed hopper. The small filter plate 109 is installed in the lower part of the feed hopper 104 and is movably connected to the inner wall. It can be disassembled and replaced as needed during actual use. It is used to initially block larger impurity particles such as straw and stalks, effectively reducing the impurity burden entering the sampling component, and also reducing contamination and interference to subsequent testing equipment.
[0036] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a dust suction port 3 is provided on the top of the device housing 17, the dust suction port 3 penetrates the device housing 17, an air duct plate 9 is provided inside the device housing 17, the air duct plate 9 is fixedly connected to the side wall of the device housing 17, the air duct plate 9 is located below the dust suction port 3, and the air duct plate 9 is fixedly connected to the buffer plate 8.
[0037] In this embodiment, dust control is achieved through a dust suction port 3 located at the top of the device. The dust suction port 3 penetrates the top of the device housing 17 and connects to an external industrial dust collection device to remove fine particulate impurities, rice husk dust, and other contaminants generated during device operation. Below it is an air duct plate 9, which forms an air guide channel through its structural design. Its upper end is close to the dust suction port 3, its lower end is fixedly connected to a buffer plate 8, and its sides are fitted and sealed against the device housing 17. The presence of the air duct plate 9 creates a stable airflow channel inside the device, preventing dust turbulence or backflow into the material path, improving dust removal efficiency and the working environment.
[0038] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a support member 14 is provided inside the outer casing 17 of the device. The support member 14 is disposed below the sample separation component 2 and is used to support the sample separation component 2.
[0039] In this embodiment, the support member 14 is located below the sampling component 2 and is arranged reasonably according to the overall shape and center of gravity of the sampling component 2. This structure is mainly used to provide longitudinal support to prevent the sampling component from sinking, shifting, or shaking under continuous impact from materials, and to ensure that the relative position between its outlet and the lower structure is always consistent, thereby ensuring the smoothness and consistency of the sampling process.
[0040] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a main board 4 is provided inside the device housing 17, the device housing 17 is fixedly connected to the main board 4, the main board 4 is connected to the sub-board 5, and the main board 4 and the sub-board 5 are used to support the sample separation component 2.
[0041] In this embodiment, a frame support structure combining horizontal and vertical components is formed by fixing a main board 4 and a secondary board 5 inside the device housing 17. The main board 4 is mostly located at the bottom or back of the sample separation component for horizontal fixation of the component. The secondary board 5 is vertically connected to the main board 4 and forms a clamp with the side wall or top structure of the device, which enhances the overall rigidity of the structure, effectively improves the vibration resistance of the sample separation component during operation, and ensures that the equipment maintains good sample separation accuracy and physical stability during long-term high-frequency operation.
[0042] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a bottom support 10 is provided inside the device housing 17. The bottom support 10 is located below the second group of sample components 2. The bottom support 10 is used to support the sample components 2. A large filter plate 13 is provided on one side of the bottom support 10. The large filter plate 13 is connected to the impurity port 16. The impurity port 16 is located at the bottom of the device housing 17. A waste port 12 is provided below the device housing 17.
[0043] In this embodiment, a bottom support 10 is provided at the bottom of the device to support the end of the second group of sample components 2. At the same time, a large filter plate 13 with a large area is provided. The filter plate is arranged on one side of the bottom support 10 and has a small pore size and a large filtration area, which can be used to separate lighter or smaller impurities and dust in the material.
[0044] The separated impurities are discharged to the outside of the device through the impurity port 16, which is connected to the filter plate, thereby preventing impurities from mixing into the test sample, improving the purity of the sample, and optimizing the accuracy and reliability of subsequent tests. The waste port 12 and the impurity port 16 are arranged side by side, and the rice husks after the impurities have been filtered are led out through the waste port 12.
[0045] like Figure 1 and Figure 2As shown, in one embodiment of the present invention, a side plate 6 is provided on one side of the device housing 17, and an observation window 7 is provided on the side plate 6 for observing the inside of the device housing 17.
[0046] In this embodiment, a second observation window 7 is provided on the side plate 6. This observation window has a similar function to the first observation window 107, but the observation angle is located on the side of the equipment. It can help the operator monitor the internal operation of the equipment from multiple directions. Especially during the debugging and maintenance phase, it is convenient to quickly identify whether the material flow is smooth or whether there are abnormal problems such as blockage, thereby improving maintenance efficiency and reducing the failure rate. The second observation window 7 is fixedly connected to the side plate 6 through the handle 15.
[0047] The working principle of this invention is as follows: The rice-brown mixture is first fed into the feed hopper 104, and the cylinder 1010 drives the insert plate 108 to move up and down to achieve quantitative release of the material. The material falls into the first group of sample components 2, and the initial disturbance and sample separation is completed by the opposite discharge direction of the adjacent sample cylinders. Then, it falls to the buffer plate 8 set in the middle for flow guidance and buffering, and then enters the second group of sample components 2 to complete the fine separation process. The qualified samples are output from the discharge port 11, and the impurities are filtered by the large filter plate 13 and discharged from the impurity port 16, effectively realizing material screening and impurity removal.
[0048] To maintain a clean environment inside the device, a dust suction port 3 is installed at the top, which, together with the air duct plate 9 below it, forms an air guiding structure to guide the dust during the sample separation process to be quickly discharged. Inside the device, the main support frame is built by the main board 4 and the sub-board 5, which, together with the support component 14 located below the sample separation component 2 and the bottom support 10, stably support the core component and prevent displacement or loosening during operation. The device also has an observation window 107 on the side of the feed hopper 104 and an observation window 7 on the side plate 6, which allows the operator to monitor the material flow and equipment status in real time.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
