Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean processing, and in particular, to a harvesting and screening device for fresh coffee beans. Background Technique

[0002] Coffee beans refer to the plant fruits used to make coffee. After the coffee beans are picked, in order to obtain high-quality coffee beans, the coffee beans need to be graded. The particle size of the coffee beans often determines the quality of the coffee beans. Therefore, it is very common to use a screening device to screen and grade the coffee beans.

[0003] In the existing public technology, the application number is: CN202021709374.8, a coffee bean screening device. Through the cooperation of structures such as a motor, a disc, a rotating shaft, a bearing, a first steel wire rope, a second steel wire rope, a sliding rod, a sliding sleeve and a spring, when the motor runs to drive the screening box to shake left and right, the first screen and the second screen vibrate following the movement of the box body, accelerating the screening of the coffee beans. While the screening box shakes left and right, due to the bottom of the chute being wavy, the screening box will generate reciprocating up and down vibrations, thereby further accelerating the screening of the coffee beans by the first screen and the second screen.

[0004] However, the above patent still has certain disadvantages when in use: when the coffee beans are piled up on the screen, it is easy to block the screen holes, resulting in a reduction in the screening efficiency, and it will also cause the un-screened coffee beans to directly flow out from the discharge pipe; the conventional method of cleaning the blocked screen suspends the screening work and then manually removes the coffee beans blocked in the screen holes, which reduces the screening efficiency to a certain extent. Moreover, the aperture of the screen used for screening is relatively single. When different degrees of screening operations are required, different types of screens need to be replaced, which is rather cumbersome to operate. This not only increases the labor intensity of the personnel, but also reduces the practicality and operation efficiency of the device, and the overall use effect is not very good.

[0005] In view of the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0029] To further illustrate the embodiments, the present invention provides drawings, which are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a harvesting and screening device for fresh coffee beans is provided.

[0031] Now, the present invention will be further described in combination with the drawings and specific implementation manners. As Figures 1-4 shown, a harvesting and screening device for fresh coffee beans according to an embodiment of the present invention includes a body 1 and a base 12. A plurality of groups of fixed grooves 18 are evenly formed on the inner surface of the body 1. A screening plate 8 is installed inside the fixed groove 18. A driving shaft 5 is installed through the middle position of the surface of the screening plate 8. An adjusting plate 10 is slidably connected to the outer periphery of the driving shaft 5 below the screening plate 8. The adjusting plate 10 is threadedly connected to the bottom surface of the screening plate 8 through a threaded rod 16. A plurality of groups of limiting holes 11 are formed around the bottom surface of the screening plate 8. A spring washer 17 is installed at the contact position between the threaded rod 16 and the adjusting plate 10. A plurality of groups of sieve holes 6 are formed on the surface of the screening plate 8, and the sizes of the sieve holes 6 gradually decrease. A plurality of groups of plugging rods 9 are installed on the surface of the adjusting plate 10.

[0032] In one embodiment, a connecting plate 3 and a dispersion rod 4 are respectively installed on the surface of the driving shaft 5 above the screening plate 8. A pushing plate 7 is installed at the bottom position of the connecting plate 3, and the pushing plate 7 abuts against the surface of the screening plate 8. The dispersion rod 4 is provided to stir the coffee beans to prevent the coffee beans from agglomerating and ensure that subsequent screening can be carried out fully. The dispersion rod 4 is composed of a plurality of metal rods welded together, and no more details will be described here.

[0033] In one embodiment, a bottom plate 13 is installed at the bottom end inside the machine body 1. The middle position at the top of the bottom plate 13 is connected to the drive shaft 5, and one end of the drive shaft 5 penetrates through one side of the bottom plate 13 and is connected to the motor 14. Collection boxes 15 are symmetrically installed at both sides of the top of the bottom plate 13. The collection boxes 15 are provided for collecting the coffee beans at the bottommost layer. Similarly, corresponding sealed doors can be opened at the positions of the screening trays 8 on the side of the machine body 1 to facilitate the removal of coffee beans of different sizes, which is convenient for subsequent use.

[0034] In one embodiment, a base 12 is fixedly installed at the bottom of the machine body 1. The device as a whole can be fixed through the base 12, which is convenient for enhancing the overall use stability.

[0035] In one embodiment, feed ports 2 are symmetrically installed at both sides of the top of the machine body 1. The provision of the feed ports 2 facilitates the addition of coffee beans, and thus facilitates subsequent screening operations.

[0036] In one embodiment, the length of the plugging rod 9 is the same as the depth of the sieve holes 6, and the size of the plugging rod 9 is the same as the size of the sieve holes 6 with the smallest aperture respectively. The setting of the size of the plugging rod 9 is to ensure that the surface of the screening tray 8 is flat and the inner diameter of the sieve holes 6 is adjusted when inserted, so as to ensure that coffee beans cannot enter, thereby avoiding missed screening.

[0037] In one embodiment, the bottom of the push plate 7 is wrapped with a silica gel pad. The silica gel pad is provided to prevent the coffee beans from being broken when being pushed, and a certain buffering effect can be achieved through the soft material.

[0038] In one embodiment, the adjusting disc 10 is of a fan-shaped structure. There are at least two groups of adjusting discs 10, and the number of adjusting discs 10 corresponds to the number of sieve hole 6 areas divided on the surface of the screening tray 8, ensuring that each time it is adjusted, the unused sieve holes 6 can be plugged to avoid the leakage of coffee beans.

[0039] Working principle: During actual use, personnel can rotate the threaded rod 16 on the surface of the adjusting disk 10 according to different required screening sizes, so that the threaded rod 16 disengages from the limiting hole 11 at the bottom of the screening disk 8. Then, the adjusting disk 10 moves downward. Next, personnel can rotate the adjusting disk 10 so that the plugging rod 9 on its surface can move to the sieve hole 6 at the designated position. Then, by resetting the adjusting disk 10 and locking it with the threaded rod 16, the fitting operation between the adjusting disk 10 and the screening disk 8 can be achieved. At this time, the plugging rod 9 can be inserted into the sieve hole 6. Since the length of the plugging rod 9 is the same as the depth of the sieve hole 6, the flatness of the surface of the screening disk 8 can be ensured when the two are fitted, thereby avoiding the hindrance of the movement of coffee beans due to the existence of depressions. At the same time, the insertion of the plugging rod 9 will also cause the unused sieve holes 6 to be filled or the aperture to become smaller, thus avoiding coffee beans from getting stuck in the sieve holes 6. As a result, coffee beans can only be screened through the unobstructed sieve holes 6. Since the type of sieve holes 6 can be set during the production stage and only by rotating the adjusting disk 10 can the change of the screening operation aperture be achieved subsequently, there is no need to replace the entire screening disk 8, effectively reducing the operation intensity and improving the overall use effect. Moreover, when a blockage occurs during screening, by moving the adjusting disk 10 and moving it upward, the blockage can be removed by inserting the plugging rod 9, without personnel having to dredge one by one, effectively reducing the dredging difficulty and improving the overall use effect. Finally, by rotating the drive shaft 5, the push plate 7 can be driven to push the coffee beans, so that the coffee beans can be screened through the sieve holes 6, facilitating personnel to obtain coffee beans of different sizes at different positions, and thus facilitating subsequent targeted processing by personnel. The overall device has the advantages of adjustable screening aperture, diverse screening types, and convenient blockage dredging.
