A movable chamber may be provided in the connecting portion in an open manner, and the connecting member may be movably inserted into the movable chamber, with one end thereof connected to one of the mounting arms and the other end connected to the other mounting arm.

[0017] According to the above embodiment, the connecting member is formed in a U shape and conforms to the shape of the support frame. The support frame is connected to the base via the connecting member, and the bottom of the support portion can either engage with the base or be separated from the base. The connecting member can prevent the support frame from completely detaching from the base when the support portion is separated from the base.

[0018] In an optional embodiment, position-limiting recesses may be respectively provided on both sides of the top of the base, and position-limiting protrusions may be respectively provided on both sides of the bottom of the support portion. By fitting the position-limiting protrusions into the position-limiting recesses, the support frame is engaged with the base.

[0019] According to the above embodiment, by configuring the two position-limiting protrusions to be respectively fitted into the two position-limiting recesses, the support frame is stably attached to the base, and it is avoided that the support frame receives uneven force and topples over to drop the fresh produce.

[0020] In an optional embodiment, a protruding block may be provided on the mounting arm. The protruding block is used to move the support frame, the roller assembly, and the fresh produce vertically upward with respect to the base under the supporting action of the weighing device for weighing the support frame, the roller assembly, and the fresh produce by the weighing device, and to release the engagement state between the support frame and the base.

[0021] According to the above embodiment, the protruding block releases the engagement state between the support frame and the base by the supporting action of the weighing device, so that the weight information of the fresh produce can be accurately obtained.

[0022] In an optional embodiment, the roller assembly may include a rotating shaft rotatably connected to the support frame, and two first rollers and one second roller disposed on the rotating shaft.

It is also necessary to explain that the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific circumstances.

[0037] The present invention provides a fresh produce sorting facility used for performing a sorting process on collected fresh produce, and is particularly suitable for sorting fruits, having a good sorting effect and high efficiency.

[0038] Referring to FIG. 1, the fresh produce sorting facility includes a plurality of fresh produce sorting and conveying devices 10, a conveyor belt 20, a roller rail 30, a detection device (not shown), a weighing device (not shown), and a fresh produce extraction device 40, etc.

[0039] In this embodiment, by clamping all of the plurality of fresh produce sorting and conveying devices 10 to the conveyor belt 20, the fresh produce sorting and conveying device 10 on which the fresh produce 50 is placed follows the conveyor belt 20 to perform the sorting process. The roller rail 30, the detection device, the weighing device, and the fresh produce extraction device 40 are all arranged around the conveyor belt 20. The detection device is used to detect the outer skin of the fresh produce 50 placed on the fresh produce sorting and conveying device 10. The weighing device is used to weigh the fresh produce 50 placed on the fresh produce sorting and conveying device 10. The fresh produce extraction device 40 is used to extract the fresh produce 50 placed on the fresh produce sorting and conveying device 10.

[0040] Referring to FIGS. 2 to 5, the fresh produce sorting and conveying device 10 according to the present invention includes a roller assembly 100, a support frame 200, a connecting member 300, and a base 400.

[0041] Among these, the roller assembly 100 is arranged on the support frame 200, the support frame 200 is movably connected to the base 400 via the connecting member 300, and is used to place the fresh produce 50 together with the roller assembly 100.

[0042] In this embodiment, the base 400 includes a reinforcing portion 420 and two clamping portions 410 provided opposite to each other. The clamping portions 410 clamp the conveyor belt 20 to move the fresh produce sorting and conveying device 10 following the conveyor belt 20. A reinforcing portion 420 is connected to the tips of the two clamping portions 410 to increase the yield strength of the base 400, greatly improving the clamping force of the clamping portions 410 on the conveyor belt 20. During the process of the fresh produce sorting and conveying device 10 conveying the fresh produce 50, the fresh produce sorting and conveying device 10 rattles and even drops due to insufficient clamping force of the clamping portions 410. This avoids damage to the fresh produce 50 caused by dropping and ensures the smooth completion of the sorting process while the fresh produce 50 is being conveyed by the fresh produce sorting and conveying device 10.

[0043] Specifically, both the reinforcing portion 420 and the two clamping portions 410 are integrally formed in a U shape, further increasing the structural strength and yield strength of the base 400 and ensuring that the clamping portions 410 stably clamp the conveyor belt 20.

[0044] In actual application, the roller assembly 100 is also used to roll the fresh produce 50. At the starting portion of the conveyor belt 20, a roller rail 30 and a detection device are provided. When the base 400 is clamped to the conveyor belt 20, the roller assembly 100 is placed on the roller rail 30. In this state, the fresh produce 50 is placed between the roller assemblies 100 of two adjacent fresh produce sorting and conveying devices 10 and rotated following the two adjacent roller assemblies 100. During the rotation of the fresh produce 50, the detection device performs a full circumferential appearance detection on the outer skin of the fresh produce 50 to collect the image information of the outer skin of the fresh produce 50.

[0045] Of course, in other embodiments, even when the fresh produce 50 is placed on the support frame 200 and the roller assembly 100 in the same fresh produce sorting and conveying device 10, the fresh produce 50 can be rolled by the roller assembly 100 rotating while being guided by the roller rail 30.

[0046] The roller assembly 100 includes a rotating shaft 110 rotatably connected to the support frame 200, and two first rollers 120 and one second roller 130 disposed on the rotating shaft 110. One second roller 130 is located between the two first rollers 120 and may be used to support the fresh produce 50 together with the two first rollers 120 or to roll the fresh produce 50.

[0047] In this embodiment, both ends of the rotating shaft 110 are respectively connected to two mounting arms of the support frame 200. The two first rollers 120 rotate while being guided by the roller rails 30, and can rotate the second roller 130, thereby rolling the fresh produce 50 and facilitating the collection of the entire peripheral skin image of the fresh produce 50.

[0048] The first roller 120 has a diameter larger than that of the second roller 130 and may be used to roll the fresh produce 50 while rotating while being guided by the roller rails 30.

[0049] In this embodiment, the second roller 130 is formed with a diameter smaller than that of the first roller 120 in order to conform to the shape of the fresh produce 50 and enhance the rolling effect of the fresh produce 50.

[0050] The support frame 200 includes a support portion 220 and two mounting arms 210 respectively connected to both ends of the support portion 220. The roller assembly 100 is disposed between the two mounting arms 210. The mounting arms 210 are provided with relief steps 212 for inserting the barb brush 60, and the relative distance between the end of the barb brush 60 and the axis of the roller assembly 100 may be reduced.

[0051] In this embodiment, a clearance step 212 for inserting the bar brush 60 is provided on the mounting arm 210, and by effectively reducing the distance between the end of the bar brush 60 and the axis of the roller assembly 100, that is, the distance between the rotation axis 110 of the first roller 120 and the end of the bar brush 60, when the dimensions of the fresh produce sorting and conveying device 10 are constant, the vertical height of the bar brush 60 can be effectively reduced, the vertical distance between the bar brush 60 and the roller assembly 100 can be reduced, and thus it is possible to effectively avoid the fresh produce 50 being caught in the gap between the bar brush 60 and the roller assembly 100. Furthermore, it is ensured that the fresh produce sorting and conveying device 10 stably conveys the fresh produce 50, avoiding damage to the fresh produce 50 caused by dropping, and ensuring that the sorting process is smoothly completed while the fresh produce 50 is being conveyed by the fresh produce sorting and conveying device 10.

[0052] Specifically, the distance between the clearance step 212 and the conveyor belt 20 clamped by the clamp portion 410 is 100 mm (shown in FIG. 7).

[0053] The mounting arm 210 may be movably connected to the base 400 via a connecting member 300.

[0054] In this embodiment, the support portion 220 and the two mounting arms 210 are both formed in a U shape. The support portion 220 is placed on the top of the base 400 and the mounting arm 210 is movably connected to the base 400 via a connecting member 300 so that the support frame 200 is movably connected to the base 400.

[0055] Note that the roller assembly 100 is guided by the roller rail 30 and is rotatable relative to the base 400 via the connecting member 300 together with the support frame 200. Specifically, it can rotate 35°. In this state, the clearance step 212 can reduce the distance between the bar brush 60 and the conveyor belt 20 by 10 mm, greatly reducing the possibility that the fresh produce 50 is caught in the space between the bar brush 60 and two adjacent fresh produce sorting and conveying devices 10 during operation.

[0056] The support part 220 includes two protruding parts 211 arranged at intervals, and the two protruding parts 221 may be used to place the fresh produce 50 together with the roller assembly 100.

[0057] In this embodiment, when the two protruding parts 221 and the roller assembly 100 contact multiple locations of the fresh produce 50 respectively, the contact area between the support frame 200 and the fresh produce 50 increases, thereby improving the adhesion effect of the support frame 200 and the roller assembly 100 on the fresh produce 50. Also, by providing the protruding parts 221, the probability of collision between the fresh produce 50 and the support frame 200 during the process of the fresh produce sorting and conveying device 10 conveying the fresh produce 50 decreases, and the damage phenomenon of the fresh produce is significantly reduced.

[0058] The base 400 further includes a connection part 430 provided at the top of the reinforcement part 420. A movable chamber 431 is provided in the connection part 430 in an open manner. The connection member 300 may be movably inserted into the movable chamber 431, with one end connected to one mounting arm 210 and the other end connected to the other mounting arm 210.

[0059] In this embodiment, the connection member 300 is formed in a U shape and is adapted to the shape of the support frame 200. The support frame 200 is connected to the base 400 via the connection member 300. The bottom of the support part 220 can be engaged with or separated from the base 400. The connection member 300 can prevent the support frame 200 from completely detaching from the base 400 when the support part 220 is separated from the base 400.

[0060] Position - limiting recesses 432 are respectively provided on both sides of the top of the connection part 430, and position - limiting protrusions 222 are respectively provided on both sides of the bottom of the support part 220. By fitting the position - limiting protrusions 222 into the position - limiting recesses 432, the support frame 200 may be engaged with the base 400.

[0061] In this embodiment, by fitting two position-limiting convex portions 222 into two position-limiting concave portions 432 respectively, the support frame 200 is stably attached to the base 400, and it is avoided that the support frame 200 receives force unevenly and topples over to drop the fresh produce 50.

[0062] When the fresh produce 50 is placed on the support frame 200, the weight of the fresh produce 50 acts on the support frame 200, and further acts on the position-limiting concave portion 432 through the position-limiting convex portion 222 of the support frame 200, so that the support frame 200 is stably engaged by the base 400, and it is prevented that the support frame 200 topples over and disengages.

[0063] In addition, when it is necessary to take out the fresh produce, as shown in FIG. 6, usually, a vertically upward force F is applied to the mounting arm 210 of the support frame 200 by the fresh produce taking-out device 40 to disengage the position-limiting convex portion 222 from the position-limiting concave portion 432. Then, the mounting arm 210 topples the support frame 200 relative to the base 400 toward the side away from the fresh produce taking-out device 40 under the action of the fresh produce taking-out device 40, and drops the fresh produce 50 from the support frame 200, thereby taking out the fresh produce 50.

[0064] It will be understood that since the support frame 200 is connected to the base 400 via the connecting member 300, when the support frame 200 topples over, it is avoided that the support frame 200 completely disengages from the base 400.

[0065] The mounting arm 210 is provided with a protruding block 211. The protruding block 211 may be used to move the support frame 200, the roller assembly 100, and the fresh produce 50 vertically upward relative to the base 400 under the supporting action of the weighing device in order to weigh the support frame 200, the roller assembly 100, and the fresh produce 50 by the weighing device, and to release the engagement state between the support frame 200 and the base 400.

[0066] In this embodiment, the weighing device is a weighing plate provided on both sides of the mounting arm 210. A weight sensor (not shown) is provided on the weighing plate (not shown). When the fresh produce sorting and conveying device 10 is moved to the position of the weighing device by the conveying belt 20, the weighing device contacts only the protruding block 211 of the mounting arm 210. In other words, the support frame 200, the roller assembly 100, and the fresh produce 50 are placed on the weighing device via the protruding block 211 of the mounting arm 210. By increasing the height of the weighing plate, the roller assembly 100, the support frame 200, and the fresh produce 50 placed on the support frame 200 are separated from the base 400, and the weight sensor acquires the weights of the support frame 200, the roller assembly 100, and the fresh produce 50, and accurate weight information of the fresh produce 50 is obtained through a series of calculations.

[0067] As described above, the present invention provides a fresh produce sorting and conveying device 10 and fresh produce sorting equipment. By clamping the conveying belt 20 by the clamping portion 410, the fresh produce sorting and conveying device 10 is moved following the conveying belt 20. Reinforcing portions 420 are connected to the tips of the two clamping portions 410 to increase the yield strength of the base 400 and greatly improve the clamping force of the clamping portion 410 on the conveying belt 20. During the process of the fresh produce sorting and conveying device 10 conveying the fresh produce 50, rattling and then dropping of the fresh produce sorting and conveying device 10 due to insufficient clamping force of the clamping portion 410 are avoided, preventing damage to the fresh produce 50 due to dropping, and ensuring that the sorting process is smoothly completed while the fresh produce 50 is conveyed by the fresh produce sorting and conveying device 10.

[0068] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various changes and modifications to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle scope of the present invention shall be included within the protection scope of the present invention.
