Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and in particular to a rice sorting and packaging device. Background Technology
[0002] After paddy rice is processed into polished rice, various factors during the processing will result in varying degrees of broken rice particles in the rice. At this time, a broken rice grading screen is needed to grade the rice, separating the whole grains from the broken grains, so that the finished rice meets the standards. Then, it is packaged and sorted, which requires a rice sorting and packaging device.
[0003] Chinese Patent No. CN222646321U discloses a rice sorting and packaging device, including a sorting and packaging device body, a rice sorting component located at the top of the sorting and packaging device body, and a rice packaging component located on one side of the sorting and packaging device body. A first packaging base and a second packaging base are provided on one side of the bottom of the sorting and packaging device body. The rice packaging component includes a gear motor, which is fixedly installed inside the first packaging base. A first gear is fixedly connected to the output end of the gear motor, and a second gear meshes with one side of the first gear. This invention, through its rice packaging component, ensures that the weight of rice in each batch of rice bags is the same, maintaining a constant weight of discharged rice. Its structure is simple, easy to use, helps improve automation, avoids human weighing or quantity errors, reduces the labor intensity of workers, and improves work efficiency.
[0004] Existing rice sorting and packaging devices have significant limitations in their structural design. They rely solely on a single-layer sorting screen to separate coarse and fine particles. This single sorting mode is insufficient to meet the needs of multi-level fine sorting, which greatly limits the applicable scenarios of the device and makes it difficult to adapt to diverse production requirements. At the same time, it is difficult to control the amount of discharge after sorting, which leads to a reduction in the structural integrity of the device and reduces its practicality.

The conveying box 104 is connected to the outer wall of the sorting box 1. The conveying box 104 is hollow inside, and inclined plates 105 are connected to both sides of the inner wall. The feed end of the conveying pipe 106 is connected to the bottom of the conveying box 104, and the discharge end of the conveying pipe 106 is connected to the buffer box 107 and connected to the inside of the buffer box 107. Two discharge outlets are provided on one side of the buffer box 107, and the discharge outlets correspond one-to-one with the discharge frame 108. The discharge frame 108 is connected to the baffle a109, and the baffle a109 is connected to the cylinder a110. The two cylinders a110 are connected below the support plate 111, and the support plate 111 is connected to the outer wall of the buffer box 107. The cylinder a110 is connected to the control system and power supply via wires. The cylinder structure used here is built based on existing mature technology. Its specific composition and working principle have been standardized in the industry, so there is no need to elaborate on the details here.

[0032] Example 2
[0033] like Figure 1 As shown, the present invention proposes a rice sorting and packaging device. Based on the above embodiments, this embodiment also details the specific components of the packaging assembly and their assembly method.
[0034] Further explanation: The packaging assembly includes a placement cylinder a2, a packaging base 201, and a hydraulic telescopic column 202; the placement cylinder a2 is connected to the packaging base 201, the packaging base 201 is connected to the hydraulic telescopic column 202, the packaging base 201 has a groove at its center, the groove is connected to a weighing sensor, and the placement cylinder a2 is connected above the weighing sensor; the hydraulic telescopic column 202 is connected to the base plate 3, the bottom of the base plate 3 is connected to a moving part 4, the moving part 4 is connected to a base 5, the base 5 is connected to a guide rail 6 and a support frame 7; the support frame 7 is connected to the outer wall of the sorting box 1. The support frame 7 supports the sorting box 1. Four packaging components are correspondingly set on the base plate 3, forming pairs and connecting to both sides of the sorting box 1. At the same time, a placement cylinder b is connected to the base plate 3, which is connected to the discharge port b112. The rice discharged from the discharge port b112 is broken rice, so there are fewer broken rice particles in the rice. This makes it convenient for the placement cylinder b to collect broken rice. The components of the rice sorting and packaging device are connected and used together. The moving part 4 includes two brackets, a motor, a threaded rod, a moving seat, and a guide rod. The two brackets are connected to the base 5, and the motor is connected to the brackets. The output end of the motor is connected to the threaded rod, which is threaded into the moving seat. The guide rod is slidably connected to both sides of the moving seat. The two ends of the guide rod are connected to the brackets respectively. One end of the threaded rod is threaded to the bracket. The base plate 3 is connected above the moving seat, so the base plate 3 can be moved through the moving part 4. A slider is connected below the base plate 3, and the slider is connected in the guide rail 6 to increase the stability of the base plate 3 during movement.
[0035] The working principle of this utility model is as follows: During use, the worker pours rice into the sorting box 1. The rice is sorted by the sorting plates a101 and b102 within the sorting box 1. Whole rice is sorted onto sorting plate a101, and semi-broken rice is sorted onto sorting plate b102. Broken rice is discharged through outlet b112 into the placement cylinder b. The finished rice and semi-broken rice sorted on sorting plates a101 and b102 are discharged through conveyors, allowing them to exit through outlet a103. The rice is discharged into the conveyor box 104, and then conveyed to the buffer box 107 through the conveyor pipe 106. The buffer box 107 is connected to the discharge frame 108 through the discharge outlet. The discharge frame 108 is inclined towards the placement cylinder a2, so that the sorted finished rice and semi-broken rice are separately discharged into the corresponding placement cylinder a2. The weighing sensor below the placement cylinder a2 is used to weigh the received rice. After the set value is completed, the discharge port b112 starts the cylinder b114. The drive end of the cylinder b114 causes the stop to be turned. Plate b113 moves toward the opening of outlet b112, closing the outlet end of outlet b112. Cylinder a110 is activated, causing baffle a109 to move downward, closing the discharge port. The base plate 3 is moved outward by the moving part 4, and the packaging assembly on the other side of the base plate 3 moves below the discharge frame 108. Another placement cylinder b is placed below outlet b112, and then cylinders a110 and b114 are used to open baffle a109 and b113. This system achieves rice sorting and processing by moving placement cylinders a and b, allowing workers to package the sorted rice. When it's necessary to control the discharge volume of sorted rice, the positions of baffles a109 and b113 are manipulated to adjust the size of the discharge port and outlet b112. For higher discharge volumes, the outlet b112 and outlet can be enlarged; for lower discharge volumes, the outlet b112 and outlet can be reduced, thus improving the ease of use of the rice sorting and packaging device.
