Description

TECHNICAL FIELD

[0001] The application belongs to the field of blueberry sorting, and particularly relates to a blueberry sorting device. BACKGROUND

[0002] Blueberries are rich in nutrients and have physiological health care functions such as promoting rhodopsin resynthesis, improving immunity and resisting cardiovascular diseases, and are listed as one of the five healthiest foods for humans by the International Food and Agriculture Organization.

[0003] Because the good and bad of blueberries are mixed after harvesting, improper postharvest processing not only affects the quality of fruits, but also affects the sales of fruits. Therefore, before the sale of blueberries, the blueberries need to be sorted, and the sorting of blueberries mainly includes impurity removal, size sorting and hardness sorting. Among them, hardness sorting is to separate relatively soft blueberries and relatively hard blueberries. Generally, relatively soft blueberries will be sold to various places after being frozen and transported over a long distance, and relatively hard blueberries will be sold to nearby supermarkets.

[0004] At present, the hardness sorting of blueberries mainly has optical sorting and bounce sorting. Since the optical sorting has high intelligentization degree and high equipment cost, the bounce sorting is the mainstream. In the prior art, the bounce sorting usually transports the blueberries to a vibrating plate arranged obliquely, a plurality of baffles parallel to each other are arranged on the vibrating plate along the conveying direction, the blueberries bounce by the vibration of the vibrating plate, and the relatively soft blueberries have the characteristics of absorbing energy due to their softness, so the bounce height is low and the relatively soft blueberries cannot pass over the baffles. The relatively soft blueberries are blown from the opposite side of the vibrating plate by the lateral air flow on one side of the vibrating plate, and vice versa, the relatively hard blueberries pass over the baffles and pass through the vibrating plate.

[0005] Since the blueberries bounce on the vibrating plate for multiple times to ensure that the blueberries with different hardness degrees can be accurately sorted, the blueberries are easily damaged, and the relatively hard blueberries are also mixed with the relatively soft blueberries when passing between adjacent vibrating plates, so the sorting accuracy is low.

[0033] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0034] As shown in Figures 1 to 6 A blueberry sorting device, comprising a soft and hard sorting mechanism and a differential conveying mechanism 1 for interval conveying adjacent blueberries to the soft and hard sorting mechanism, the soft and hard sorting mechanism comprises a fruit conveying channel 2, a sorting conveying channel 3 and a cyclic hardness sorter 4, the width of the fruit conveying channel 2 is only for a single blueberry of corresponding size to pass through, and the cyclic hardness sorter 4 is arranged between the output end of the fruit conveying channel 2 and the input ends of the two sorting conveying channels 3.

[0035] The cyclic hardness sorter 4 comprises a plurality of flexible energy storage tabs 401 located on the same circle and a rotating assembly provided with the plurality of flexible energy storage tabs 401, the plurality of flexible energy storage tabs 401 can rotate around the same axis by means of the rotating assembly, the plurality of flexible energy storage tabs 401 sequentially receive the blueberries output by the fruit conveying channel 2 through rotation, the flexible energy storage tab 401 converts the kinetic energy of the received blueberries into elastic potential energy for absorption, and the blueberries are respectively thrown to the two sorting conveying channels 3 according to the difference in softness and hardness by releasing the elastic potential energy.

[0036] The plurality of elastic energy storage paddles 401 are arranged to receive the blueberries in turn by rotating, and the elastic energy storage paddles 401 have elasticity and convert the kinetic energy of the blueberries into elastic potential energy when receiving the blueberries. With the rotation of the elastic energy storage paddles 401, the component force of the elastic energy storage paddles 401 in the radial direction of the rotating path gradually decreases, so that the elastic energy storage paddles 401 can throw the blueberries to the sorting conveying channels 3. Due to the difference in hardness of the blueberries, the softer blueberries will deform more than the harder blueberries when being thrown by the elastic energy storage paddles 401 to the sorting conveying channels 3, that is, the softer blueberries will consume more kinetic energy due to their own deformation when being thrown, resulting in that the softer blueberries are pushed for a shorter distance and the softer blueberries are separated from the elastic energy storage paddles 401 later, so that blueberries with different degrees of hardness can be pushed to two sorting conveying channels 3 respectively to realize the sorting of blueberries with different degrees of hardness.

[0037] On the one hand, the elastic energy storage paddles 401 are used to gently receive the blueberries, and then the elastic energy storage paddles 401 are used to release the elastic potential energy to change the conveying path of the blueberries, so that the blueberries are conveyed to the corresponding sorting conveying channels 3 according to the degree of hardness, thereby reducing the damage to the blueberries caused by the hardness sorting of the circulating hardness sorter 4. On the other hand, the plurality of elastic energy storage paddles 401 are arranged to continuously receive the blueberries one by one and convey the blueberries to the corresponding sorting conveying channels 3 according to the degree of hardness of the blueberries, thereby avoiding the existing bounce sorting method that the blueberries will bounce multiple times when passing through the hardness sorting device, and further reducing the damage to the blueberries caused by the hardness sorting.

[0038] The rotating assembly includes a fixed shaft 402 and a rim 403 arranged to rotate on the fixed shaft 402. The fixed shaft 402 is fixedly arranged outside the fruit conveying channel 2 by a support 5. The elastic energy storage paddles 401 are arranged on the rim 403. The end of the fruit conveying channel 2 is provided with a gap 6 for the plurality of elastic energy storage paddles 401 to pass through the fruit conveying channel 2 in turn.

[0039] The wheel rim 403 is provided with an annular cavity 7 coaxial with the fixed shaft 402, and the side surface of the wheel rim 403 is provided with a plurality of wide-mouth holes 8 communicating with the annular cavity 7. One end of the elastic energy storage paddle 401 is hingedly provided with a connecting rod 9, and the wide-mouth hole 8 and / or the connecting rod 9 are provided with a connecting rod locking assembly 10 for locking the connecting rod 9 after the elastic energy storage paddle 401 is deformed and the connecting rod 9 is pushed into the annular cavity 7. The annular cavity 7 is provided with a connecting rod unlocking assembly 11 for unlocking the connecting rod 9 by the connecting rod locking assembly 10, so that the elastic energy storage paddle 401 can release the elastic potential energy instantaneously, thereby avoiding the problem that the elastic potential energy of the elastic energy storage paddle 401 is slowly released with the rotation of the elastic energy storage paddle 401, the pushing distance of the blueberries is small, it is difficult to adapt to the hardness sorting needs of heavy blueberries, and the sorting effect and the blueberry throwing path are unstable.

[0040] The connecting rod locking assembly 10 includes an arc-shaped locking spring piece 1001 and a limiting protrusion 1002. The arc-shaped locking spring piece 1001 is in an arch shape and is arranged on the hole wall of the wide-mouth hole 8. The limiting protrusion 1002 is arranged on the side surface of the connecting rod 9. The limiting protrusion 1002 overcomes the resistance of the arc-shaped locking spring piece 1001 and passes through the gap between the arc-shaped locking spring piece 1001 and the hole wall of the wide-mouth hole 8 by means of the deformation of the elastic energy storage paddle 401. The connecting rod unlocking assembly 11 resets the limiting protrusion 1002 by pushing the connecting rod 9 to overcome the resistance of the arc-shaped locking spring piece 1001, so that the elastic energy storage paddle 401 can release the elastic potential energy instantaneously.

[0041] The connecting rod unlocking assembly 11 includes an impact spring piece 1101 and a wedge-shaped block 1102. The wedge-shaped block 1102 is wedge-shaped, and a plurality of wedge-shaped blocks 1102 are arranged on the cavity wall of the annular cavity 7 on the side provided with the wide-mouth hole 8. The wide-mouth hole 8 is located between adjacent wedge-shaped blocks 1102.

[0042] The annular cavity 7 is in communication with the hole of the wheel rim 403 axis, one end of the impact spring piece 1101 is in clearance fit with the cavity wall of the annular cavity 7 on the side provided with the wide-mouth hole 8, and the other end is fixedly arranged on the fixed shaft 402. The impact spring piece 1101 slides over the surface of the wedge-shaped block 1102 and elastically deforms with the rotation of the wheel rim 403, and one end of the impact spring piece 1101 impacts the connecting rod 9 when reaching between adjacent wedge-shaped blocks 1102, so that the limiting protrusion 1002 resets to overcome the resistance of the arc-shaped locking spring piece 1001.

[0043] The impact spring 1101 cooperates with the wedge-shaped block 1102 to increase the resistance of the rotation of the wheel rim 403, so that the blueberry exerts a circumferential resistance on the elastic energy storage paddle 401 when contacting the elastic energy storage paddle 401, and the elastic energy storage paddle 401 can absorb the kinetic energy of the blueberry. At the same time, the impact spring 1101 is deformed and stored by means of the rotation of the wheel rim 403 and the wedge-shaped wedge-shaped block 1102, and the unlocking of the connecting rod 9 is realized.

[0044] The differential conveying mechanism 1 comprises a low-speed conveying belt 101 and a high-speed conveying belt 102 arranged in sequence along the conveying direction to convey the adjacent blueberries to the fruit conveying channel 2, the low-speed conveying belt 101 and the high-speed conveying belt 102 are connected by the transition platform 12, and the low-speed conveying belt 101 and the high-speed conveying belt 102 are gap-fitted with the transition platform 12, so as to realize the separation of the adjacent blueberries in close contact, facilitating the rotation of the elastic energy storage paddle 401 to reach between the adjacent blueberries.

[0045] In addition, the end of the fruit conveying channel 2 is provided with an impeller 13, the side surface of the impeller 13 is provided with a plurality of elastic leaf plates 14, the two sides of the fruit conveying channel 2 are provided with side frames 15, the impeller 13 is rotationally arranged on the side frame 15, the side frame 15 is provided with a speed reducer motor 16 connected with the impeller 13, and the impeller 13 pushes the blueberries to the elastic energy storage paddle 401 by means of the rotation of the elastic leaf plate 14, so as to facilitate the rotation of the wheel rim 403 and the deformation of the elastic energy storage paddle 401, wherein the plurality of elastic leaf plates 14 are staggered with the plurality of elastic energy storage paddles 401, that is, the number of the elastic leaf plates 14 is the same as that of the elastic energy storage paddles 401, the elastic leaf plates 14 push the blueberries to the elastic energy storage paddles 401 in front, and the elastic energy storage paddles 401 behind are rotated to above the fruit conveying channel 2, so that the elastic leaf plates 14 and the elastic energy storage paddles 401 behind can be matched in the same way.

[0046] Preferably, the elastic leaf plate 14 adopts a thin plate with elasticity, so that the elastic leaf plate 14 can gently contact the blueberry and reduce the damage to the blueberry.

[0047] The working principle of the present application is as follows:

[0048] The blueberries in the column are sequentially conveyed to the fruit conveying channel 2 by the low-speed conveying belt 101, the transition platform 12 and the high-speed conveying belt 102 in a two-by-two spaced manner. At the end of the fruit conveying channel 2, the rotating impeller 13 pushes the front blueberries to the inclined elastic energy storage paddle 401 by means of the elastic leaf plate 14 located between the adjacent two blueberries, the kinetic energy of the blueberries is used to deform the elastic energy storage paddle 401, and the rim 403 provided with the elastic energy storage paddle 401 is rotated, when the elastic energy storage paddle 401 is deformed, the connecting rod 9 at the end of the elastic energy storage paddle 401 is driven to move into the annular cavity 7, the limiting protrusion 1002 on the side of the connecting rod 9 overcomes the resistance of the arc-shaped locking spring sheet 1001, and the arc-shaped locking spring sheet 1001 is deformed and restored after the limiting protrusion 1002 passes through the narrow opening, so that the elastic energy storage paddle 401 is prevented from recovering. When the elastic energy storage paddle 401 rotates to a horizontal or nearly horizontal position, the impact spring 1101 which has completed energy storage through the wedge block 1102 releases the elastic potential energy, so as to impact the connecting rod 9, the connecting rod 9 overcomes the resistance of the arc-shaped locking spring sheet 1001 and returns to the original position, and the elastic potential energy accumulated by the elastic energy storage paddle 401 is released instantaneously. Due to the different hardness of the blueberries, the softer blueberries will deform more than the harder blueberries when being thrown to the sorting conveying channel 3 by the elastic energy storage paddle 401, that is, the softer blueberries will consume more kinetic energy due to the deformation of the blueberries when being thrown, so that the softer blueberries are pushed for a shorter distance, and the softer blueberries are separated from the elastic energy storage paddle 401 later, so that the blueberries with different hardness can be pushed to two sorting conveying channels 3 respectively, so as to realize the sorting of the blueberries with different hardness.

[0049] It is to be understood by those skilled in the art that the present application can be implemented by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above disclosed embodiments are merely exemplary in all aspects and are not the only ones. All changes within the scope of the present application or within the equivalent scope of the present application are intended to be included in the present application.
