Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee bean sorting technology, specifically a coffee bean sorting device. Background Technology
[0002] In the production and processing of coffee beans, screening is a crucial step. Its purpose is to select coffee beans that meet specific specifications in order to improve the overall quality and consistency of the coffee beans.
[0003] In traditional technology, an arc-shaped dispersing plate is usually set in the feed chute, allowing coffee beans to roll forward on the feed chute by their own gravity. When the coffee beans pass through the perforations inside the arc-shaped dispersing plate, the screening function is achieved. However, this screening method that relies solely on gravity rolling has obvious drawbacks: two or more coffee beans can easily get stuck in the perforations inside the arc-shaped dispersing plate at the same time. Once this happens, the screening process will be obstructed, and the stuck coffee beans need to be cleaned manually, which increases labor costs and production time and reduces the screening efficiency of coffee beans. Therefore, a coffee bean screening device is proposed to solve the above problems. Utility Model Content
[0004] In view of the shortcomings of the prior art, the present invention provides a coffee bean sorting device to overcome the deficiencies of the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A coffee bean sorting device includes a base plate. Four limiting vertical rods are fixedly installed on the top of the base plate. The four limiting vertical rods are arranged in pairs, one in front and one behind. The height of the front pair of limiting vertical rods is less than the height of the rear pair of limiting vertical rods. Lifting plates are slidably installed on the outside of each pair of limiting vertical rods. Two side plates are fixedly installed between the two lifting plates. A sorting assembly is provided on the top of each of the two lifting plates. A vibration transmission frame is fixedly installed on the bottom of each of the two lifting plates. A vibration motor is fixedly installed on the bottom of the vibration transmission frame. A stop ring is fixedly installed on the outside of each of the four limiting vertical rods. Springs are fixedly installed on the top and bottom of each of the two lifting plates, sleeved on the outside of the four limiting vertical rods. The four lower springs are respectively located on the top of the four stop rings.
[0007] The screening assembly includes a screening box fixedly installed on the top of two lifting plates. A V-shaped plate is fixedly installed inside the screening box, and multiple perforations are opened at the bottom of the V-shaped plate.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, a feeding cover is fixedly installed on the back of the screening box. The outer side of the feeding cover is L-shaped and extends through the interior of the screening box.
[0010] Furthermore, discharge cylinders are fixedly installed on both the left and right sides of the screening box. The discharge cylinders are connected to the screening box in a through manner. Both discharge cylinders are located at the end near the left side of the V-shaped plate, and the outlets of both discharge cylinders face downwards.
[0011] Furthermore, the top of the base plate is provided with two collection boxes, which are located below the screening box and the two discharge cylinders, respectively.
[0012] Furthermore, a sponge pad is fixedly installed on the bottom of the inner wall of both collection boxes.
[0013] Furthermore, the top of the base plate has two grooves, and the two collection boxes are slidably installed inside the two grooves respectively.
[0014] Furthermore, the external structure of the vibration transmission frame is "I" shaped, and the vibration motor is located at the midpoint of the vibration transmission frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the vibration motor generates vibration, which drives the lifting plate and the top screening box to vibrate through the vibration transmission frame. After the coffee beans are put into the screening box, they shake. Small-diameter coffee beans roll out to the right through the bottom perforation of the V-shaped plate under the action of gravity and vibration, thus achieving screening. Vibration can prevent coffee beans from clogging the perforation, thereby improving screening efficiency. Attached Figure Description

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0024] Example 1, as Figures 1-5 As shown, a coffee bean sorting device includes a base plate 1. Four limiting vertical rods 2 are fixedly installed on the top of the base plate 1. The four limiting vertical rods 2 are arranged in pairs, one in front and one behind. The height of the front pair of limiting vertical rods 2 is less than the height of the rear pair of limiting vertical rods 2. Lifting plates 3 are slidably installed on the outside of each pair of limiting vertical rods 2. Two side plates 4 are fixedly installed between the two lifting plates 3. A sorting component is provided on the top of the two lifting plates 3. A vibration transmission frame 5 is fixedly installed on the bottom of the two lifting plates 3. A vibration motor 6 is fixedly installed on the bottom of the vibration transmission frame 5. A stop ring 7 is fixedly installed on the outside of each of the four limiting vertical rods 2. Springs 8 are fixedly installed on the top and bottom of each of the two lifting plates 3 and are sleeved on the outside of the four limiting vertical rods 2. The four springs 8 are located on the top of the four stop rings 7 respectively.
[0025] Specifically, the screening assembly includes a screening box 9 fixedly installed on the top of two lifting plates 3. A V-shaped plate 10 is fixedly installed inside the screening box 9, and multiple perforations 11 are opened at the bottom of the V-shaped plate 10.
[0026] Four limiting vertical rods 2 restrict the two lifting plates 3 to slide above the base plate 1. At this time, two side plates 4 connect the two lifting plates 3 into a whole. Multiple springs 8 sleeved on the outside of the four limiting vertical rods 2 support the upper and lower ends of the two lifting plates 3 respectively. The vibration motor 6 can generate vibration, which can drive the two lifting plates 3 and the sieving box 9 installed on the top of the two lifting plates 3 to vibrate through the vibration transmission frame 5. After coffee beans are put into the sieving box 9, they will shake. At this time, under the action of gravity, small-diameter coffee beans will roll to the right through multiple perforations 11 opened at the bottom of the V-shaped plate 10, thereby realizing the screening of coffee beans. During the screening process, the vibration can effectively prevent two or more coffee beans from blocking the perforations 11, thereby improving the screening efficiency of coffee beans.
[0027] Example 2, as Figures 1-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0028] A feeding cover 12 is fixedly installed on the back of the screening box 9. The outer side of the feeding cover 12 is L-shaped and extends through the interior of the screening box 9.
[0029] This design allows for easy addition of coffee beans to the sieving box 9 via the feeding hood 12 for sieving.
[0030] Example 3, as Figures 1-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0031] The left and right sides of the screening box 9 are fixedly installed with discharge cylinders 13. The discharge cylinders 13 are connected to the screening box 9. Both discharge cylinders 13 are located at the left end near the V-shaped plate 10, and the outlets of both discharge cylinders 13 face downward.
[0032] With this setup, large-diameter coffee beans will be concentrated on the left and right sides of the V-shaped plate 10 due to vibration, and then discharged to the outside through the two discharge cylinders 13.
[0033] Example 4, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0034] The top of the base plate 1 is provided with two collection boxes 14, which are located below the screening box 9 and the two discharge cylinders 13, respectively.
[0035] With this configuration, the two collection boxes 14 collect the coffee beans falling from the sieve box 9 and the two discharge cylinders 13 respectively, thereby achieving the purpose of classified storage.
[0036] Example 5, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 4, and its specific details are as follows:
[0037] Both collection boxes 14 have sponge pads 15 fixedly installed on the bottom of their inner walls.
[0038] This design allows the soft sponge pad 15 to prevent coffee beans from falling into the collection box 14 and then popping outwards.
[0039] Example 6, as Figure 4 As shown, this embodiment is a further improvement based on embodiment 4, and its specific details are as follows:
[0040] The top of the base plate 1 has two grooves 16, and two collection boxes 14 are slidably installed inside the two grooves 16 respectively.
[0041] With this configuration, the two chutes 16 can restrict the position of the two collection boxes 14, so that the coffee beans falling from the two discharge cylinders 13 of the sieve box 9 can accurately fall into the interior of the two collection boxes 14.
[0042] Example 7, as Figures 3-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0043] The external structure of the vibration transmission frame 5 is "I" shaped, and the vibration motor 6 is located at the midpoint of the vibration transmission frame 5.
[0044] This configuration allows the vibration generated by the vibrating motor 6 to be evenly transmitted to the two lifting plates 3 and the screening box 9.
[0045] Working principle;
[0046] Four limiting vertical rods 2 restrict the two lifting plates 3 to slide above the base plate 1. At this time, two side plates 4 connect the two lifting plates 3 into a whole. Multiple springs 8, which are sleeved on the outside of the four limiting vertical rods 2, support the upper and lower ends of the two lifting plates 3 respectively. The vibration motor 6 can generate vibration, which drives the two lifting plates 3 and the sieving box 9 installed on the top of the two lifting plates 3 to vibrate through the vibration transmission frame 5. After coffee beans are put into the sieving box 9, the coffee beans will shake with the sieving box 9. Under the action of gravity, small-diameter coffee beans will roll to the right through multiple perforations 11 opened at the bottom of the V-shaped plate 10, thereby realizing the screening of coffee beans. During the screening process, the vibration can effectively prevent two or more coffee beans from blocking the perforations 11, thereby improving the screening efficiency of coffee beans. After passing through the feeding hood 12, it is convenient to add coffee beans into the sieving box 9 for screening. Large-diameter coffee beans will be concentrated on the left and right sides of the V-shaped plate 10 due to the vibration. Then, they can be discharged to the outside through the two discharge cylinders 13.
[0047] The two collection boxes 14 are designed to collect coffee beans falling from the sieve box 9 and the two discharge cylinders 13, respectively, thus achieving the purpose of classified storage. A soft sponge pad 15 prevents coffee beans from popping out after falling into the collection box 14. Two sliding grooves 16 restrict the position of the two collection boxes 14, ensuring that coffee beans falling from the sieve box 9 and the two discharge cylinders 13 accurately fall into the two collection boxes 14.
[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
