The embodiment provides a blueberry screening device 100, which can sort fresh picked blueberry fruits, and further distinguish the picked blueberry fruits according to different fruit diameters by removing sundries in the picked blueberry fruits, so as to meet the requirement of deep processing of the blueberry fruits with different fruit diameters.

In order to reduce possible damage and destruction to blueberry fruits in the screening process, sundries such as leaves, paper scraps and the like generated in the process of picking blueberry fruits are removed in a winnowing mode, and the method is realized in a secondary removal mode. Further, during the second sundry removal, blueberry fruits are sorted, so that fruits with different fruit diameters can be obtained separately and independently.

See fig. 1-4.

Fig. 1 is a schematic structural diagram of a blueberry screening device according to an embodiment of the present invention. Referring to fig. 1, the present embodiment provides a blueberry filter 100. The blueberry screening device 100 comprises a feed chute 103, a back blower, a feed cylinder 104, a secondary separation plate 405 and a base 102.

Wherein the feed chute 103 and the blowback device cooperate to remove impurities mixed in the blueberry fruit. The feeding barrel 104 and the secondary sorting plate 405 can be matched to remove sundries and sort blueberry fruits with different fruit diameters. The base 102 then serves as the basis for the blueberry screen 100 for the installation and securing of the components.

Further details regarding the various components are provided below.

Fig. 2 is a schematic view of the structure of the feed chute. Referring to fig. 2, a chute 103 is provided as a first pass processing equipment for the blueberry screen 100. The feeding chute 103 mainly conveys blueberry fruits and limits the fruits to a specific space and distribution state so as to clean sundries in combination with a back blower.

The material of the feed chute 103 may be selected from various materials, and the present invention is not limited thereto, and for example, the feed chute 103 is formed by welding a steel plate or an iron plate or an aluminum plate. Alternatively, in some examples, the chute 103 is molded using a plastic or resin mold.

In this embodiment, the chute 103 has a U-shaped configuration and defines a chamber 302 for delivering blueberry fruit. The feeding chute 103 may be of a split structure design or of an integrally formed structure design. The feed chute 103 includes a bottom wall, a left side wall, and a right side wall. Wherein the left side wall and the right side wall are connected to opposite sides of the bottom wall. The feed chute 103 is generally cylindrical and has a feed end and a discharge end. The feed chute 103 extends entirely between the feed end and the discharge end. The feed end serves as the initial portion of the blueberry fruit entering the blueberry screen 100 and the discharge end serves as the portion of the blueberry fruit exiting the chute 103. Preferably, the bottom wall is provided with a plurality of hemispherical protrusions in order to reduce the build-up of blueberry fruits, the hemispherical protrusions should be arranged in a suitable way to reduce the blocking of blueberries. Further, the feed chute 103 is also matingly secured by a vibrator. The blueberry fruits are loosened by the vibration feeding groove 103, so that the blueberry fruits are transported more easily, sundries are exposed more easily, and the blueberry fruits are removed.

In the blueberry screen 100, the feed chute 103 is arranged obliquely, and is arranged obliquely in such a manner that the feed end is higher than the discharge end. The blueberry fruit is transported under its own weight by the inclined arrangement of the feed chute 103.

To facilitate placement of the blueberry fruit into the chute 103, the chute 103 has a feeding platform 301 at the feeding end, with the feeding platform 301 being horizontally disposed. The blueberry fruits can be spread out through the feeding platform 301, so that accumulation is reduced, and sundries are fully exposed.

In combination with the feed chute 103, a blowback (not shown) cooperates therewith to effect the removal of impurities. The back blower takes the jet air flow as a working mode, and the jet direction of the jet air flow is opposite to the conveying direction of the blueberry fruits in the feed chute 103. The number of the back blowers may be one or more, and is selected according to the implementation form of the back blowers.

When the number of blowbacks is one, the blowbacks may be connected to the left side wall or the right side wall. When there are a plurality of blowbacks, for example, two, three, or even more, the plurality of blowbacks are connected to the left side wall and the right side wall, respectively. Further, the number of the back blowers connected to the left side wall and the right side wall is equal and staggered with each other, so that sundries can be blown off the blueberry fruits more efficiently and accurately. The manner of setting the back-blower may be selected in various ways, and may be selected according to the structure of the back-blower and the size of the feed chute 103 so as to remove impurities, but the air outlet of the back-blower is limited in such a way as to be arranged from the discharge end toward the feed end.

Fig. 3 is a schematic structural view of the feed cylinder. Referring to fig. 3, a feeder drum 104 is provided as a member for receiving blueberry fruits which are removed from impurities by a feeder tank 103. The feeder canister 104 is generally cylindrical and extends from top to bottom. The feed cylinder 104 is axially provided with a channel. The whole feeding barrel 104 is mainly made of metal or other materials.

The feed chute 103 and the feed cylinder 104 are connected and matched in the following manner: the discharge end of the chute 103 is connected between and adjacent to the top and bottom ends. Preferably, the discharge end of the feed chute 103 is directly coupled to the feed cylinder 104 and does not extend into the passage of the feed cylinder 104 so that the blueberry fruit may drop directly into it, thereby allowing for a more rapid separation of debris from the blueberry fruit for removal of the debris by the air flow created by the suction fan 403. In addition, the top end of the feed cylinder 104 is connected to a suction fan 403 which creates a bottom-to-top airflow in the channel. When the suction fan 403 is turned on, an air flow is formed in the channel of the feeding barrel 104, so that impurities are removed.

Fig. 4 is a schematic view of the structure of a secondary sorting deck. Also disposed within the channel of the feeder drum 104 is a secondary sorting deck 405 as shown in fig. 4. The secondary sorting deck 405 includes a first sorting deck 401 and a second sorting deck 402 arranged in order in a top-to-bottom direction. The first sorting plate 401 and the second sorting plate 402 may be made of the same material or different materials. The first sorting deck 401 and the second sorting deck 402 are held within the channel of the feeder drum 104, for example by a cage or other structure. However, the peripheral edges of the first sorting deck 401 and the second sorting deck 402 are each spaced from the inner wall of the feeder drum 104 so that the suction fan 403 creates a suction air flow therethrough. Further, the first sorting plate 401 and the second sorting plate 402 are staggered with each other, so that the first sorting plate and the second sorting plate are staggered with a gap formed by the inner wall of the feeding barrel 104, so that stronger air flow is formed in the feeding barrel 104, and the impurity removing effect is enhanced.

Based on the sorting requirements, both the first sorting plate 401 and the second sorting plate 402 are provided with sorting holes. Wherein the first sorting plate 401 is provided with a plurality of first sorting holes and the second sorting plate 402 is provided with a plurality of second sorting holes 406. And the aperture of the first sorting aperture is larger than the aperture of the second sorting aperture 406.

Further, the blueberry screen 100 is also a blower, the first sorting plate 401 and the second sorting plate 402 have air inlets provided with a plurality of air blowing holes and communicated with the air blowing holes, the blower is connected with an air supply pipe, and one end of the air supply pipe away from the blower is held in the air inlets in a sealing manner. By forming the air exhausting effect in the first sorting plate 401 and the second sorting plate 402, impurities can be removed more directly. Furthermore, the blowing holes are communicated with the sorting holes, and impurities attached to the surfaces of the blueberry fruits can be removed better when the blueberry fruits pass through the sorting holes.

Preferably, the blueberry screen 100 further includes a vibrator. The vibrator is configured to vibrate the first sorting plate 401 and the second sorting plate 402. One implementation of the vibrator is an electromagnetic vibrator. In some examples, the vibrator includes a ferrous fixation plate 603, an electromagnet 601, and a spring 602. Wherein the electromagnet 601 is fixed on the outer wall of the feeding cylinder 104, the fixing plates 603 are respectively connected with the first sorting plate 401 and the second sorting plate 402, and the springs 602 are supported and held between the outer wall of the feeding cylinder 104 and the first sorting plate 401 and the second sorting plate 402. The electromagnet 601 attracts the fixing plate 603 and the spring 602 to be in telescopic fit, so that the first sorting plate 401 and the second sorting plate 402 can reciprocate in the radial direction of the feeding barrel 104, and the screening effect is achieved.

In addition, the first sorting plate 401 and the second sorting plate 402 are also provided with rotators, respectively, based on the sorting demand of the fruits after the screening is completed. The bottom end is provided with a bottom cover which can be opened and closed, and the base 102 is also provided with a feeding belt 501. When the blueberry fruits need to be recovered, the bottom cover is opened, so that the first sorting plate 401 and the second sorting plate 402 are purposefully opened, and the blueberry fruits fall into the feeding belt 501 and are further conveyed to a destination.

In the blueberry screen 100, a base 102 is provided as a base. The base 102 provides attachment points and attachment points for the various components and provides support for the various components. The feed chute 103 and the feed cylinder 104 are connected and fixed to the base 102 by a bracket 503, and an air pump 502 matching with the back blower is also fixed to the base 102. More preferably, the base 102 is provided with universal wheels so that the blueberry screen 100 can be moved as desired.
