This coffee bean sorting device uses the leveling rods to operate the coffee beans, preventing them from piling up. The vibration motor drives the sorting chamber to vibrate, and the sorted coffee beans are removed by opening and closing the door. Smaller, defective coffee beans are located at the bottom of the sorting chamber, resulting in faster and better sorting. Meanwhile, the larger coffee beans at the top contain fewer impurities, facilitating production operations.
[0004] The aforementioned patent only uses a screening chamber, a leveling bar, and a vibration motor to achieve two-stage sieving of coffee beans by size, which cannot fully sieve the coffee beans more finely, and it is also not easy to solve the problem of coffee bean mesh clogging.
[0005] Therefore, it is necessary to invent a coffee bean sorting device with a multi-stage sorting structure to solve the above problems. Utility Model Content

Detailed Implementation
[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-6 The coffee bean sorting device shown includes a support plate 001, a discharge tank 101 fixedly connected to the inner wall of the support plate 001, a sieving tank 102 fixedly connected to the upper end of the discharge tank 101, the discharge tank 101 communicating with the sieving tank 102, an inlet 103 fixedly connected through the inside of the sieving tank 102, the inlet 103 communicating with the inside of the sieving tank 102, and a plurality of sliding grooves 402 fixedly connected to the inner wall of the sieving tank 102, with a first sieving screen 201 and a second sieving screen 202 slidably connected to the inner wall of the plurality of sliding grooves 402. Screening meshes 202, 203, 204, and 205, and screening meshes 201, 202, 203, 204, and 205 are slidably connected inside screening tank 102. Two vibrating motors 206 are fixedly connected to the lower end of support plate 1001. The lower end of support plate 1001 is fixedly connected to the output end of multiple spring rods 104. Support plate 205 is fixedly connected to the lower end of the multiple spring rods 104. When… During coffee bean sorting, coffee beans are poured into the feed inlet 103. After initial filtration by the first screening screen 201, they undergo further grading filtration by the second screening screen 202, third screening screen 203, fourth screening screen 204, and fifth screening screen 205, separating coffee beans of different sizes. This process drives two vibration motors 206, which in turn vibrate the support plate 1001. The vibration of the support plate 1001 then vibrates the discharge tank 101, which in turn vibrates the screening tank 102. The vibration of screen 102 causes the first screening screen 201, the second screening screen 202, the third screening screen 203, the fourth screening screen 204, and the fifth screening screen 205 to vibrate, assisting in the grading and screening of coffee beans. Multiple spring rods 104 reduce the vibration of the device to ensure the stability of the device during operation. After screening, hold the handles on the side wall of the first screening screen 201, the second screening screen 202, the third screening screen 203, the fourth screening screen 204, and the fifth screening screen 205 to remove them, and you can get standard-sized coffee beans.
[0027] The side wall of the screening tank 102 is connected to a dust cover 107 via a hinge. When screening coffee beans, the dust cover 107 is closed to prevent dust from entering and affecting the quality of the coffee beans.
[0028] A fan 304 is fixedly connected to the upper end of the support plate 2 105, and a dust collection box 305 is also fixedly connected to the upper end of the support plate 2 105. The input end of the fan 304 is connected to the inside of the dust collection box 305. A connecting pipe 306 is fixedly connected through the inside of the screening tank 102. A suction port 307 is fixedly connected to the side wall of the connecting pipe 306 and is connected to the inside of the connecting pipe 306. A filter box 301 is fixedly connected through the inside of the screening tank 102. Two fans 302 are fixedly connected inside the filter box 301. When the fans 302 are started, they blow away the impurities mixed in with the coffee beans, blowing large pieces of impurities to the opening of the suction port 307. This drives the fan 304, which then sucks in the large pieces of impurities through the suction port 307 into the connecting pipe 306. The impurities then enter the dust collection box 305 for collection, facilitating subsequent centralized processing.
[0029] A filter screen 303 is detachably connected inside the filter box 301, and a filter plate 308 is detachably connected inside the dust collection box 305. A filter cotton core 309 is detachably connected inside the filter plate 308. The filter screen 303 filters the air entering the screening tank 102. After the debris enters the dust collection box 305, it is filtered by the filter cotton core 309 inside the filter plate 308 and temporarily stored in the dust collection box 305 to ensure the long-term stable operation of the fan 304.
[0030] Anti-clogging balls 401 are installed at the upper ends of the second screening mesh 202, the third screening mesh 203, the fourth screening mesh 204, and the fifth screening mesh 205. When the second screening mesh 202, the third screening mesh 203, the fourth screening mesh 204, and the fifth screening mesh 205 are vibrating and screening, multiple anti-clogging balls 401 bounce and impact the first screening mesh 201, the second screening mesh 202, the third screening mesh 203, the fourth screening mesh 204, and the fifth screening mesh 205 to prevent coffee beans from clogging in the mesh, thereby preventing clogging from causing a decrease in screening efficiency.
[0031] Multiple support seats 106 are fixedly connected to the lower end of the support plate 2 105. The multiple support seats 106 support the entire device and ensure the stability of the device during operation.
[0032] The working principle of this product is as follows: When screening coffee beans, the beans are poured into the feed inlet 103. After initial filtration by the first screening screen 201, they undergo further grading filtration by the second screening screen 202, the third screening screen 203, the fourth screening screen 204, and the fifth screening screen 205, separating coffee beans of different sizes. This process drives two vibration motors 206, which in turn vibrate the support plate 1001, causing it to vibrate. The vibration of the support plate 1001 then vibrates the discharge tank 101, resulting in the discharge of coffee beans. The vibration of tank 101 causes the sieving tank 102 to vibrate, which in turn causes the first sieving screen 201, the second sieving screen 202, the third sieving screen 203, the fourth sieving screen 204, and the fifth sieving screen 205 to vibrate, thus assisting in the grading and screening of coffee beans. After screening, hold the handles on the side of the first sieving screen 201, the second sieving screen 202, the third sieving screen 203, the fourth sieving screen 204, and the fifth sieving screen 205 and remove them to obtain coffee beans of standard size.
[0033] When fan 302 is turned on, it blows away impurities mixed in with the coffee beans, moving large pieces of impurities to the opening of suction port 307. This drives fan 304, which sucks in the large pieces of impurities through suction port 307 into connecting pipe 306. The impurities then enter dust collection box 305. After entering dust collection box 305, the impurities are filtered by the filter cotton core 309 inside filter plate 308 and temporarily stored in dust collection box 305 to ensure the long-term stable operation of fan 304.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
