Description

Technical Field

[0001] This utility model relates to the field of rice production technology, and in particular to a rice sorting machine. Background Technology

[0002] In the agricultural product processing sector, rice, as one of the main food crops, plays a crucial role in the sorting process. Traditional rice sorting methods largely rely on manual operation, which is not only inefficient but also struggles to guarantee sorting accuracy and consistency. With advancements in technology and the development of automation, mechanized rice sorting equipment has emerged on the market, improving sorting efficiency and accuracy to some extent. However, existing rice sorting machines still have some shortcomings in practical applications.

[0003] Firstly, in terms of storage and initial screening, traditional rice sorting equipment typically only has simple storage functions and lacks an efficient screening mechanism, making it difficult to effectively remove impurities and defective grains from the rice. This not only affects the quality of the rice but also increases the difficulty and cost of subsequent processing.

[0004] Secondly, in the sorting and storage stage, existing rice sorting equipment often lacks flexibility and precision. Due to the differences in rice grain size and quality, sorting and storing them is crucial to ensuring the quality of the final product. However, some equipment cannot achieve precise control during sorting and storage, resulting in rice of different qualities being mixed together, thus reducing the added value of the product.

[0026] In this embodiment, the storage and screening assembly 2 is located above the base plate 1 and mainly consists of a storage box 201, a storage discharge pipe 202, a screening horizontal plate 203, a guide shaft 204, a limiting plate 205, a connecting plate 206, a screening spring 207, a vibration motor 208, and a screening box 209.

[0027] Storage box 201 is used to store rice grains to be sorted. A storage discharge pipe 202 is provided on the side wall of storage box 201 for discharging rice grains to the lifting assembly 6. A screening horizontal plate 203 is symmetrically arranged on the inner wall of storage box 201. The screening horizontal plate 203 is equipped with a guide shaft 204 and a limiting plate 205 for fixing and guiding the connecting plate 206. A screening spring 207 is provided between the connecting plate 206 and the screening horizontal plate 203, giving the connecting plate 206 a certain elasticity, thus accommodating rice grains of different sizes. A vibration motor 208 is provided on the connecting plate 206, which, through vibration, performs preliminary screening of the rice grains in the screening box 209. At the bottom of the screening box 209, multiple evenly arranged storage screening holes 210 are provided for discharging the screened rice grains.

[0028] In this embodiment, the components arranged between the support frames 3 are mainly composed of a collection box 401, a sorting partition 402, a guide block 403, and a discharge pipe 404.

[0029] The collection box 401 is used to receive rice grains discharged from the conveying and screening assembly 5. Inside the collection box 401, there are multiple evenly arranged sorting partitions 402 for classifying and storing rice grains according to different sizes. At the bottom of the collection box 401, there are multiple pairs of guide blocks 403 for guiding the rice grains to the discharge pipe 404. On the discharge pipe 404, there is a discharge switch 405 for controlling the discharge of rice grains.

[0030] In this embodiment, the conveying and screening component 5 is disposed above the classification and storage component 4, and mainly consists of a first conveying support frame 501, a second conveying support frame 502, a conveying and screening box 503, a pallet 504, a conveying motor 505, and a screening and conveying auger 506.

[0031] Conveyor support frame 1 501 and conveyor support frame 2 502 are used to support the conveyor screening box 503.
