Description

Technical Field

[0001] The present application relates to the technical field of coffee processing equipment, and specifically relates to a coffee bean screening machine. Background Art

[0002] Coffee beans refer to the fresh fruits of plants used to make coffee. After the coffee fresh fruits are picked from the coffee tree, they first need to go through multiple processes such as peeling, degumming, drying, storage, shelling, and polishing, and then become the coffee beans that we can buy in the market after roasting. Coffee beans come in different sizes, and coffee beans of different particle sizes belong to different qualities. In order to obtain high-quality coffee beans, it is necessary to classify the coffee beans and then process them.

[0003] During the classification process of coffee beans, generally, a screening mechanism is used to screen out coffee beans of different particle sizes to ensure the quality of the coffee finished product.

[0004] The raw material of coffee beans generally contains certain impurities, such as light coffee fresh fruit shells, broken bean shells, and dust. However, most of the existing coffee bean screening devices can only screen coffee beans by size, and the screened coffee beans will contain light impurities, which will affect the final quality of the coffee;

[0005] In the prior art, the coffee beans to be screened can be decontaminated by a decontamination device first and then the screening operation can be carried out. However, the above operation usually requires two or more devices for the coffee bean screening operation, which not only prolongs the processing time of coffee beans, affects the processing efficiency, but also increases the workload of the operators, and requires a large amount of manpower and material resources. Therefore, it is necessary to provide a coffee bean screening machine to solve the above problems.

[0038] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0039] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] As Figures 1-3 shown, the present application provides a coffee bean screening machine, including a base 1. A storage barrel 4 is fixedly installed at the upper end of the base 1. The storage barrel 4 is used to store coffee beans to be screened. A discharge port 41 is provided on one side of the bottom of the storage barrel 4, and it is convenient for coffee beans to enter the next process through the discharge port 41;

[0041] And a stirring mechanism 3 is provided between the storage barrel 4 and the base 1. In the present application, the stirring mechanism 3 is used to stir the coffee beans in the storage barrel 4. In the present application, the stirring mechanism 3 has a drive motor disposed between the storage barrel 4 and the base 1, and stirring blades installed at the bottom of the storage barrel 4. The output shaft of the drive motor penetrates through the bottom of the storage barrel 4 and is fixed to the stirring blades. Therefore, starting the drive motor can drive the stirring blades to rotate. It should be noted that the stirring mechanism 3 is a conventional technology in this field, and specific information can be consulted in relevant materials, and will not be elaborated here.

[0042] At the upper end of the base 1, a screening mechanism 2 is also installed. The screening mechanism 2 is located on one side of the storage bin 4. The screening mechanism 2 has a screening barrel 21 inclinedly arranged at the upper end of the base 1. The screening barrel 21 is used to screen the coffee beans in the storage bin 4. At the upper end of the side of the screening barrel 21 close to the storage bin 4, a feed inlet 211 is opened. At the upper end of the feed inlet 211, a feed pipe 22 is fixedly installed. The other end of the feed pipe 22 is connected to the discharge port 41. Therefore, the coffee beans in the storage bin 4 come out from the discharge port 41, enter the feed pipe 22, and then enter the screening barrel 21 through the discharge port 41 for screening operation.

[0043] In order to fix the screening barrel 21, a connecting frame 23 is fixedly installed below the end of the screening barrel 21 far from the storage bin 4. The bottom end of the connecting frame 23 is rotatably connected to the upper end of the base 1. Therefore, the screening barrel 21 can rotate on the upper end of the base 1 through the connecting frame 23;

[0044] At the same time, a support frame 24 is fixedly installed below the end of the screening barrel 21 close to the storage bin 4. And a fixing frame 11 is also fixedly installed on the upper end of the base 1. The fixing frame 11 is located below the support frame 24, and the fixing frame 11 is connected to the support frame 24. Therefore, the end of the screening barrel 21 close to the storage bin 4 is higher than the other end, so it is convenient for the coffee beans to slide downward along the inclination angle of the screening barrel 21 under the action of gravity.

[0045] And three groups of filtering components are uniformly fixedly installed at the lower end of the screening barrel 21. The three groups of filtering components are the first filtering component 25, the second filtering component 26, and the third filtering component 27 from top to bottom. In this application, the structures and installation methods of the first filtering component 25, the second filtering component 26, and the third filtering component 27 are the same. For the convenience of understanding, the following takes the first filtering component 25 as an example for elaboration. Specifically:

[0046] The first filtering component 25 has a screening plate 251. The screening plate 251 is arranged inside the screening barrel 21. A plurality of groups of filtering holes are opened on the screening plate 251. In this application, for the convenience of installing the filtering component, the bottom of the screening barrel 21 is provided with a slot (not marked in the figure). Opposite ends of the slot face inward and are fixedly provided with fixing strips 212. The screening plate 251 is arranged above the fixing strips 212, and a compression spring 253 is fixedly installed between the fixing strips 212 and the screening plate 251. At the same time, a blanking hopper 254 is arranged below the screening plate 251. The blanking hopper 254 is fixed to the lower end of the fixing strip 212;

[0047] Therefore, when the coffee beans enter the screening barrel 21 through the feed inlet 211 and fall onto the screening plate 251, the gravity of the coffee beans will push the screening plate 251 downward, causing the compression spring 253 to contract. Subsequently, the reaction force of the compression spring 253 will push the screening plate 251 upward, thus making the screening plate 251 shake up and down. The coffee beans are filtered through the filter holes on the screening plate 251, and the filtered materials will then enter the lower discharge hopper 254, thereby achieving the first filtration and screening of the coffee beans.

[0048] And a baffle 252 is fixedly installed at the lower end of the screening plate 251, thus preventing the unfiltered coffee beans from sliding downward and entering the next set of filtering components.

[0049] It should be noted that the diameters of the filter holes in the first filter component 25, the second filter component 26, and the third filter component 27 are different. Among them, the diameter of the filter holes in the first filter component 25 is smaller than that of the second filter component 26, and the diameter of the filter holes in the second filter component 26 is smaller than that of the third filter component 27. Therefore, the dust and broken bean husks in the coffee beans are screened and filtered through the first filter component 25, the smaller coffee beans are screened and filtered through the second filter component 26, and finally the larger coffee beans are screened through the third filter component 27, thereby achieving the screening operation of coffee beans of different sizes.

[0050] At the same time, a collection mechanism 5 is also provided below the screening barrel 21. The collection mechanism 5 includes a first collection component 51, a second collection component 52, and a third collection component 53. In this application, the structures and installation methods of the first collection component 51, the second collection component 52, and the third collection component 53 are the same. For the convenience of understanding, the following will take the first collection component 51 as an example for explanation. Specifically:

[0051] The first collection component 51 has a mounting plate 512 fixed to the upper end of the base 1. Above the mounting plate 512, there is a collection box 511. The collection box 511 is located below the first filter component 25. And on both sides of the upper end of the mounting plate 512, there are fixed guide rails 514. During installation, the collection box 511 is inserted into the guide rails 514, thus preventing the collection box 511 from shaking and also enabling the quick installation of the collection box 511.

[0052] One side end of the collection box 511 is fixedly installed with a handle 513. The position of the collection box 511 can be conveniently moved through the handle 513. When the collection box 511 is full, the collection box 511 is pulled out through the handle 513 for replacement or emptying.

[0053] In this application, the first collection component 51 is located below the first filter component 25, the second collection component 52 is located below the second filter component 26, and the third collection component 53 is located below the third filter component 27, thus facilitating the collection of the screened materials.

[0054] As Figure 2 and Figure 4 shown, in order to facilitate the adjustment of the inclination angle of the screening bucket 21, a through hole 241 is formed through the support frame 24. An installation hole 242 is coaxially formed on the side of the through hole 241 away from the fixing frame 11. A nut 243 is installed in the installation hole 242. At the same time, a connection groove 111 is formed on the fixing frame 11. A bolt 112 is installed in the connection groove 111 and the through hole 241. The bolt 112 is threadedly connected to the nut 243. Therefore, when it is necessary to adjust the inclination angle of the screening bucket 21, loosen the bolt 112. At this time, adjust the height of the screening bucket 21 and the support frame 24, so that the support frame 24 drives the bolt 112 to slide in the connection groove 111. After adjusting to the appropriate height, tighten the bolt 112 again.

[0055] In summary: When screening coffee beans, pour the coffee beans to be screened into the storage bucket 4. Subsequently, the coffee beans enter the screening bucket 21 and directly fall onto the first filter element 25. The first filter element 25 screens the dust and broken bean husks in the coffee beans. The screened dust and broken bean husks fall downwards and fall into the first collection member 51 through the feeding hopper 254;

[0056] The unscreened coffee beans enter the second filter element 26 through the baffle 252 with the elastic force of the screening plate 251. Similarly, the smaller coffee beans are screened, and the screened coffee beans fall into the second collection member 52;

[0057] The remaining coffee beans enter the third filter element 27 and are screened and collected in the same way, thereby shortening the processing time of the coffee beans, improving the processing efficiency, reducing the workload of the operator, saving manpower and material resources, and at the same time facilitating the adjustment of the inclination angle of the screening device.

[0058] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
