When the fruit tray brakes to the designated position, the external device lifts the fruit tray, causing the fruit tray and the adapter plate to move upward together until the limiting shaft disengages from the locking position. Then, the external device pushes the fruit tray to one side, causing the limiting shaft to slide to one end of the arc-shaped elongated hole. At this time, the fruit tray is tilted, and the fruit on the fruit tray can fall to the designated position, realizing fruit sorting. The whole structure is relatively simple, does not occupy too much space, and has a relatively low cost. Attached Figure Description

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0025] Example:

[0026] like Figures 1-7 As shown, this embodiment provides a fruit sorting device, installed on a roller chain serving as a conveyor chain. It includes a fruit tray 1, a connecting plate 2, and a chain support 3 connected to the outer links of the roller chain, allowing the chain support 3 to move with the roller chain. The connecting plate 2 is slidably connected to the chain support 3 in a vertical direction, allowing the connecting plate 2 to move up and down relative to the chain support 3. A rotating shaft 4 is installed on the connecting plate 2. A connecting plate 101 is provided on one side of the fruit tray 1, and the lower part of the connecting plate 101 is rotatably connected to the rotating shaft 4, allowing the fruit tray 1 to rotate relative to the connecting plate 2, so that water on the fruit tray 1 can be sorted at a designated position. The fruit is unloaded; the upper part of the connecting plate 101 is provided with an arc-shaped elongated hole 102 with the rotating shaft 4 as the central axis. The upper part of the chain bracket 3 is equipped with a limiting shaft 5, one end of which is inserted into the arc-shaped elongated hole 102. The horizontal height of the arc-shaped elongated hole 102 gradually increases from one end to the other end. The other end of the arc-shaped elongated hole 102 is provided with an upwardly extending locking position. One end of the limiting shaft 5 is fitted into the locking position, so that the limiting shaft 5 can slide relative to the arc-shaped elongated hole 102. When one end of the limiting shaft 5 is fitted into the locking position, the stability of the fruit tray 1 can be ensured due to its own weight, which facilitates the transportation of fruit.

[0027] In operation, one end of the limiting shaft 5 is fitted into the locking position. The roller chain of the conveyor chain drives the fruit tray 1 to run along a fixed trajectory through the chain bracket 3. After the fruit falls onto the fruit tray 1, the conveyor chain continues to run. When the fruit tray 1 is braked to the designated position, the external device lifts the fruit tray 1, causing the fruit tray 1 and the adapter plate 2 to move upward together until the limiting shaft 5 disengages from the locking position. Then, the external device pushes the fruit tray 1 to one side, causing the limiting shaft 5 to slide to one end of the arc-shaped elongated hole 102. At this time, the fruit tray 1 is tilted, and the fruit on the fruit tray 1 can fall to the designated position, realizing the sorting of fruit. The whole structure is relatively simple, does not occupy too much space, and has a relatively low cost.

[0028] As a preferred embodiment of this invention, it should be further explained that the lower part of the connecting plate 101 is provided with a stepped hole, which includes a first circular hole and a second circular hole that are sequentially connected from one end of the connecting plate 101 away from the chain bracket 3 to the other end. The inner diameter of the first circular hole is larger than the inner diameter of the second circular hole. A first flange bearing 6 is matched and installed in the stepped hole, so that the first flange bearing 6 can only move towards one end of the connecting plate 101. The inner ring of the first flange bearing 6 is sleeved on the outside of the rotating shaft 4, so that the connecting plate 101 has better flexibility when rotating relative to the rotating shaft 4. A first retaining groove is provided on the rotating shaft 4, and a first retaining spring 7 is engaged in the first retaining groove. The first retaining spring 7 abuts against the end of the first flange bearing 6 away from the chain bracket 3, so as to ensure the stability of the first flange bearing 6 and prevent the first flange bearing 6 from sliding at will, and also ensure the stability of the connecting plate 101 on the rotating shaft 4.

[0029] As a preferred embodiment of this invention, it should be further explained that the upper part of the chain bracket 3 is provided with a longitudinally elongated hole extending in the vertical direction. The longitudinally elongated hole includes a third elongated hole and a fourth elongated hole that are connected sequentially from one side of the chain bracket 3 to the other side. The width of the fourth elongated hole is greater than the width of the third elongated hole. A second flange bearing 8 is matched and installed in the longitudinally elongated hole, so that the second flange bearing 8 can only move to the other side of the chain bracket 3. A pin 9 is installed on the adapter plate 2. One end of the pin 9 is matched and penetrates the inner ring of the second flange bearing 8. Thus, when the adapter plate 2 drives the pin 9 to rise and fall together, the friction can be reduced by the second flange bearing 8. A second slot is provided on one end of the pin 9. A second retaining spring is engaged in the second slot. The second retaining spring abuts against the end of the second flange bearing 8 away from the adapter plate 2 to ensure that the second flange bearing 8 is stably installed in the longitudinally elongated hole. It should be noted that in this embodiment, one or two longitudinal elongated holes can be provided. When one longitudinal elongated hole is provided, two second flange bearings 8 are preferably installed in the longitudinal elongated hole; when two longitudinal elongated holes are provided, only one second flange bearing 8 can be installed in each longitudinal elongated hole.

[0030] As a preferred embodiment of this invention, it should be further explained that the upper part of the fruit tray 1 has two longitudinal elongated holes, and two second flange bearings 8 are matched and installed in each longitudinal elongated hole, which can better ensure that the adapter plate 2 can drive the fruit tray 1 to slide stably on the chain bracket 3 in the vertical direction.

[0031] As a preferred embodiment of this invention, it should be further explained that a third slot is provided at one end of the limiting shaft 5, and a third retaining spring is engaged in the third slot. The third retaining spring abuts against the side of the connecting plate 101 away from the chain bracket 3, thereby ensuring the stability of the limiting shaft 5 and the cooperation effect between the limiting shaft 5 and the connecting plate 101.

[0032] As a preferred embodiment of this invention, it should be further explained that the upper part of the fruit tray 1 is a horizontally arranged U-shaped support frame 103, with the opening of the U-shaped support frame 103 facing away from the chain bracket 3. The upper end of the connecting plate 101 is connected to the middle part of the U-shaped support frame 103, preferably integrally formed. A support roller 104 is rotatably connected to the middle part of the U-shaped support frame 103. Two support wheels 105 are installed between the two side plates of the U-shaped support frame 103. The support roller 104 and the two support wheels 105 cooperate to form a triangular support structure, thereby enabling the fruit tray 1 to be stably supported between the support roller 104 and the two support wheels 105. Both support wheels 105 are conical wheels with diameters decreasing from one end away from each other to the other, thereby enabling the fruit to be more stably supported between the two support wheels 105. Furthermore, the support roller 104 can have a structure with a diameter that gradually increases from the middle to both ends, which makes the fruit more stable when supported between the support roller 104 and the two support wheels 105.

[0033] As a preferred embodiment of this example, it should be further noted that both support wheels 105 are mounted on the mounting shaft, and mounting holes 106 are correspondingly provided on the two side plates of the U-shaped support frame 103. The two ends of the mounting shaft are respectively inserted into the mounting holes 106 of the two side plates. It should be noted that in practice, the U-shaped support frame 103 is made of plastic and has a certain degree of elasticity, which can easily realize the mounting shaft loading and unloading.

[0034] As a preferred embodiment of this invention, it should be further explained that at least two mounting holes 106 distributed along the length of the side plates are provided on both side plates of the U-shaped support frame 103, and the mounting holes 106 on the two side plates are set in a one-to-one correspondence, so that the position of the two support wheels 105 can be adjusted, that is, the distance between the two support wheels 105 and the support roller 104 can be adjusted to better adapt to different fruits.

[0035] As a preferred embodiment of this invention, it should be further explained that the U-shaped support frame 103 has an upward-facing mounting groove in the middle, and fixed shafts are provided on both sides of the mounting groove. The support roller 104 has a first locking groove and a second locking groove at both ends, and the first locking groove and the second locking groove are located on both sides of the support roller 104. The first locking groove and the second locking groove are respectively locked onto the two fixed shafts. In actual installation, the first locking groove can be engaged with one fixed shaft first, and then the support roller 104 can be rotated so that the second locking groove is engaged with the other fixed shaft, thereby realizing the installation of the support roller 104 and ensuring the stability of the support roller 104.

[0036] As a preferred embodiment of this invention, it should be further explained that the lower end of the chain bracket 3 is provided with two mounting plates 301 for connecting to the outer links of the roller chain. The two mounting plates 301 are arranged in parallel. In practice, the two mounting plates 301 can be directly welded to the outer links, or two fixing plates can be welded to the outer links, and then the two mounting plates 301 are connected to the two fixing plates, for example, by bolt connection.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
