[0002] Pecans, also known as American pecans, long-shell pecans, pecans, and longevity nuts, are a nut rich in nutrients and widely used. During pecan processing, to prevent the presence of shriveled nut shells, which affect their nutritional value and taste, and increase processing difficulty, a screening device is used to effectively separate out the low-quality shriveled nut shells, thus ensuring the quality of the final product.

[0003] The feed port of the thin-shell pecan fruit empty screening device generally adopts a straight-through structure. The fruit falls directly into the screening box through the feed port for screening. Since the cross-section of the feed port is smaller than the screening area, the fruit will be in a clustered state when falling through the feed port. The empty fruits are easily hidden among the full fruits, resulting in the wind force of the screening device being unable to effectively act on the empty fruits, making it difficult for the empty pecans to be blown away by the wind, reducing the efficiency and accuracy of screening.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 7 The present embodiment provides a thin-shell pecan fruit empty screening device, comprising a screening box 1, a top of the screening box 1 is provided with a feed port 3 connected thereto through a top cover 2, and a hopper assembly 4 is provided on the feed port 3, a driving assembly 5 for driving the hopper assembly 4 to swing back and forth is provided on the top cover 2 at a position on one side of the feed port 3, the interior of the screening box 1 is divided into a first chamber 7 and a second chamber 8 by a partition 6, a blowing assembly 9 for blowing air toward the second chamber 8 is provided near the top of the screening box 1, and a first discharge port 10 and a second discharge port 11 connected to the first chamber 7 and the second chamber 8 are respectively provided on the front and rear sides of the screening box 1.

[0027] In the present invention, the thin-shelled pecan fruits that need to be screened are poured into the screening box 1 through the hopper assembly 4 of the feed port 3, and the hopper assembly 4 is swung back and forth on the feed port 3 by the driving assembly 5, so that the pecans entering the screening box 1 through the hopper assembly 4 are more dispersed, and the blowing assembly 9 blows air in a direction perpendicular to the falling direction of the pecans. Since the weight of full pecan fruits is much greater than the weight of empty pecan fruits, under the action of lateral wind force, the empty pecan fruits will be blown farther due to their lighter weight, and thus fall into the second chamber 8 behind the partition 6 and are discharged from the screening box 1 through the second discharge port 11, while the full fruits with heavier weight are blown closer, so as to fall into the first chamber 7 in front of the partition 6 and be discharged through the first discharge port 10, thereby completing the empty screening of thin-shelled pecan fruits.

[0028] Specifically, such as Figure 2-Figure 4 As shown, the hopper assembly 4 includes a hopper body 41 rotatably mounted on the feed port 3 via a connecting shaft 42 , and a bearing matching the connecting shaft 42 is provided on the feed port 3 .

[0029] Among them, the connecting shaft 42 of the bucket body 41 passes through the bearing of the feed port 3, so that the bucket body 41 can be transmitted inside the feed port 3, and then the bucket body 41 can swing back and forth under the reciprocating drive of the drive component 5. When the thin-shelled pecan fruit passes through the bucket body 41 and enters the screening box 1, the reciprocating swinging bucket body 41 can make the pecan fruit more dispersed, avoiding the fruit aggregation and causing the wind force to be unable to effectively act on the empty fruit.

[0030] Specifically, such as Figure 2-Figure 5 As shown, the drive assembly 5 includes a mounting frame 51 fixed on the top cover 2, a screw 53 is provided on the mounting frame 51 through a motor 52, and a slide 54 is provided on the screw 53 to match it, a gear 43 is provided at the end of the connecting shaft 42 away from the bucket body 41, and a tooth plate 55 meshing with the gear 43 is provided on the top of the slide 54.

[0031] Among them, when the motor 52 drives the screw 53 to rotate, the slide 54 cooperating with the screw 53 will translate on the screw 53, thereby driving the tooth plate 55 to move. Since the tooth plate 55 is engaged with the gear 43, the gear 43 will be driven to rotate when the tooth plate 55 moves, and then the bucket body 41 is driven to rotate on the feed port 3 through the connecting shaft 42. As the motor 52 rotates in the opposite direction, the slide 54 is reset, and then the bucket body 41 rotates in the opposite direction, thereby realizing the reciprocating swing of the bucket body 41, ensuring that the thin-shelled pecan fruits entering the screening box 1 through the bucket body 41 can fall more dispersedly in the screening box 1, thereby ensuring that the pecan fruits can be more fully exposed to the action of wind, making the empty pecans more easily blown away by the wind.

[0032] Specifically, such as Figure 2 and Figure 4As shown, the bucket body 41 includes a middle section 411 located inside the feed port 3 , a funnel section 412 communicating with the middle section 411 is provided at the top, and a nozzle section 413 extending to the inside of the screening box 1 is provided at the bottom of the middle section 411 .

[0033] Among them, the middle section 411 is cylindrical, so that it can swing more conveniently. The funnel section 412 can ensure that the thin-shelled pecan fruits can accurately fall on the bucket body 41. The nozzle section 413 extends inside the screening box 1, so that when the bucket body 41 swings, it can ensure that the pecan fruits are dispersed in the screening box 1.

[0034] Specifically, such as Figure 2 and Figure 7 As shown, the blowing assembly 9 includes a mounting cover 91 connected to the screening box 1, a blower 92 is provided on the side of the mounting cover 91 away from the screening box 1, and an air distribution plate 93 is provided on the end of the mounting cover 91 located inside the screening box 1, and a plurality of evenly arranged air guide holes 94 are opened on the air distribution plate 93.

[0035] Among them, the blower 92 blows air toward the second chamber 8, and the blown air can be blown out more evenly after passing through the air guide holes 94 on the air distribution plate 93. The uniform wind force can ensure that the pecans are subjected to consistent force during the screening process, making it easier to blow out the empty pecans, while the full pecans remain in the screening area, thereby improving the efficiency and accuracy of the screening.

[0036] It should be noted that the air guide hole 94 includes an inlet section 941 and an acceleration section 942, which are arranged in sequence along the blowing direction of the blower 92, and the inlet section 941 is connected to the acceleration section 942. The inlet section 941 has a truncated cone-shaped hole structure, and the acceleration section 942 has a cylindrical hole structure. The narrow opening of the inlet section 941 faces the blowing direction and is connected to the acceleration section 942. When the air from the blower 92 is discharged through the air guide hole 94, the wind passes through the inlet section 941 with a large cross-section and enters the acceleration section 942 with a small cross-section, thereby accelerating the wind to blow out. By increasing the wind speed, it ensures that the shriveled fruits can be accurately blown into the second chamber 8, improving the accuracy of screening.

[0037] Specifically, such as Figure 2 As shown, a first guide plate 12 inclined toward the first discharge port 10 is provided at the bottom of the first chamber 7 , and a second guide plate 13 inclined toward the second discharge port 11 is provided at the bottom of the second chamber 8 .

[0038] Among them, the inclined first guide plate 12 and the second guide plate 13 can play a guiding role. When the full fruits and the shriveled fruits fall into the first chamber 7 and the second chamber 8 due to wind force, the inclined guide plates can make the full fruits and the shriveled fruits roll toward the first discharge port 10 and the second discharge port 11 respectively, thereby facilitating the discharge of the screened pecan fruits.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
