Description

Technical Field

[0001] This utility model relates to the field of grain screening equipment technology, and in particular to a rice length selection machine. Background Technology

[0002] As one of the world's major food crops, the quality of rice is directly related to people's dietary health and satisfaction. Length, as an important indicator of rice quality, not only affects the appearance of the rice but also has a close relationship with its taste and nutritional value after cooking.

[0003] A search of existing technology revealed a Chinese patent entitled "A Multi-Roller Rice Length Grading Machine," application number "202320509966.2." This patent primarily includes a base, with the main body of the machine fixedly mounted on top. The top of the main body has a feed inlet. Multiple rollers are arranged sequentially from top to bottom inside the main body, with a discharge outlet fixedly connected to the bottom of each roller. A stirring mechanism is installed inside each roller, and a screen is fixedly installed inside each roller. A discharge hose extending from one end of each roller is fixedly installed outside the main body. A tilting mechanism is located at the bottom of each roller. A drawer is fixedly installed on the inner bottom wall of the main body, and a cleaning mechanism is provided on the main body. While this invention facilitates the discharge of the selected rice and the cleaning of the internal rollers, making it convenient to use, rice remaining on the screen needs to be discharged through the discharge hose under gravity via the tilting mechanism. This discharge method requires frequent machine stops to complete the discharge, preventing continuous operation of the entire screening process, reducing production efficiency, and failing to meet the demands of modern rice processing enterprises for efficient and continuous production. Therefore, this utility model provides a rice length selection machine to solve the problems mentioned in the background art. Utility Model Content

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses a rice length-selection machine, which includes a base plate 1. A support plate 2 is fixedly connected to one side of the top of the base plate 1. A rotating shaft 3 is rotatably connected to the top of the support plate 2. A mounting plate 4 is fixedly connected to one end of the rotating shaft 3. An outer cylinder 5, a first screen 6, and a second screen 7 are sequentially fixedly connected from the outside to the inside on the side of the mounting plate 4 opposite to the rotating shaft 3. The lengths of the second screen 7, the first screen 6, and the outer cylinder 5 increase sequentially, and the aperture of the first screen 6 is smaller than that of the second screen 7, enabling multi-stage screening. Gaps are provided between the outer cylinder 5, the first screen 6, and the second screen 7 to ensure smooth flow of rice during the screening process. Furthermore, the ends of the second screen 7 and the first screen 6 are fixedly connected to a ring-shaped baffle 8. A feeding box 9 is embedded inside the bottom plate 1 and below the baffle 8. Two partitions 10 are fixedly connected inside the feeding box 9 and below the baffle 8. Three feeding ports are formed inside the feeding box 9 through the partitions 10. A feeding hopper 11 is fixedly connected at the bottom of the feeding box 9 and below each feeding port for collecting the screened rice separately. The baffle 8 is slidably connected to the top of the corresponding partition 10.

[0023] The rice to be screened is conveyed into the second screen 7 through its opening. Simultaneously, the rotating shaft 3 rotates, causing the mounting plate 4 to rotate, which in turn drives the outer cylinder 5, the first screen 6, and the second screen 7 to rotate synchronously. After being screened by the second screen 7, the rice that is not screened automatically falls into the first screen 6. The first screen 6 then performs further screening for different lengths, with the remaining rice automatically falling into the outer cylinder 5. Through the rotation of the outer cylinder 5, the first screen 6, and the second screen 7, rice of different lengths inside can be conveyed to the outside through their corresponding openings. The rice conveyed from these openings falls into the corresponding discharge ports, is discharged from the feed box 9, and collected separately, thus completing the rice length screening process. The overall screening process is simple and efficient, enabling continuous rice screening and precise length screening, thereby improving screening efficiency.

[0024] A U-shaped fixing frame 18 is fixedly connected to the top of the base plate 1 and above the feeding box 9. The fixing frame 18 is spaced apart from the adjacent baffle 8 to avoid contact between the fixing frame 18 and the baffle 8. A screw feeder 12 is fixedly connected to the top of the fixing frame 18 and inside the second screen 7. The discharge port of the screw feeder 12 extends to the side close to the mounting plate 4 to evenly transport the rice to be screened into the second screen 7.

[0025] In order to drive the rotating shaft 3 to rotate, a control component is provided on the top of the base plate 1 and on the side near the rotating shaft 3. The control component includes a motor 14 fixedly connected to the top of the base plate 1 and two pulleys 13. One pulley 13 is fixedly connected to the end of the rotating shaft 3 opposite to the mounting plate 4, and the other pulley 13 is fixedly connected to the output shaft of the motor 14. The two pulleys 13 are connected by belt drive.

[0026] When the motor 14 starts, it drives the rotating shaft 3 and the mounting plate 4 to rotate together through the belt drive, which can better drive the outer cylinder 5, the first screen 6 and the second screen 7 to rotate synchronously, thereby realizing the screening of rice.

[0027] Two rolling assemblies for supporting the outer cylinder 5 are also provided at the top of the base plate 1 and below the outer cylinder 5. These assemblies support the outer cylinder 5 and reduce friction during rotation. The rolling assemblies include a connecting plate 17 with a circular structure that is fixedly connected to the outside of the outer cylinder 5, four fixing plates 15 that are fixedly connected to the top of the base plate 1, and two rollers 16. Each pair of fixing plates 15 are adjacent and opposite to each other. The rollers 16 are installed between each pair of adjacent fixing plates 15. The rollers 16 are all in rolling connection with the connecting plate 17 to ensure that the outer cylinder 5 can move smoothly during operation.

[0028] Working principle: The rice to be screened is evenly conveyed into the second screen 7 by the screw feeder 12. At the same time, the motor 14 starts and drives the rotating shaft 3 and the mounting plate 4 to rotate together through belt drive, which can better drive the outer cylinder 5, the first screen 6 and the second screen 7 to rotate synchronously, thereby realizing the screening of rice.

[0029] After the rice is screened by the second screen 7, the rice that is not screened automatically falls into the first screen 6. The first screen 6 then performs screening for different lengths, and the rice that is not screened automatically falls into the outer cylinder 5. Through the rotation of the outer cylinder 5, the first screen 6, and the second screen 7, rice of different lengths inside can be conveyed to the outside through their corresponding openings. The rice conveyed from the openings falls into the corresponding discharge ports, is discharged from the feed box 9, and is collected separately, thus completing the screening of rice by length. The overall screening process is simple and efficient, enabling continuous screening of rice and precise screening of rice by length, which helps to improve screening efficiency.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
