Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a rotating connection mechanism and a fruit and vegetable sorting device. Background Technology

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include citrus fruits, cherries, apples, pears, and tomatoes. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.

[0003] In related technologies, a fruit and vegetable sorting device may include a rotating connecting mechanism and multiple gripping components for gripping fruits and vegetables. The multiple gripping components may be arranged around the same turntable. The rotating connecting mechanism is connected to the turntable. The motor of the fruit and vegetable sorting device can drive the turntable to rotate through the rotating connecting mechanism, thereby driving the gripping components to move around the rotating connecting mechanism. During the movement of the gripping components, fruits and vegetables can be gripped and transported to another location.

[0004] However, the turntable and all the gripping components have a large mass, and the turntable will generate a large torque during rotation, which may cause the rotating connection mechanism to shake, reducing the stability of the fruit and vegetable sorting device during operation. Utility Model Content

[0005] The present invention aims to provide a rotating connecting mechanism and a fruit and vegetable sorting device to solve the technical problem in the prior art that the large torque generated by the turntable during rotation may cause the rotating connecting mechanism to shake.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0007] A rotary connection mechanism is provided, comprising:

[0008] The mounting bracket includes a first mounting plate and a second mounting plate spaced apart from each other. The first mounting plate has a first mounting through groove, and the second mounting plate has a second mounting through groove.

[0009] A rotating shaft assembly, wherein the rotating shaft assembly passes through the first mounting through groove and the second mounting through groove;

[0010] A first bearing assembly is located at the first mounting slot, and the rotating shaft assembly is rotatably connected to the first mounting plate via the first bearing assembly.

[0011] The second bearing assembly is located at the second mounting slot, and the rotating shaft assembly is rotatably connected to the second mounting plate via the second bearing assembly.

[0012] With the above structure, the rotating shaft assembly is rotatably connected to the first mounting plate via the first bearing assembly, and the rotating shaft assembly is rotatably connected to the second mounting plate via the second bearing assembly; so that during the rotation of the rotating shaft assembly, the first mounting plate can support the rotating shaft assembly via the first bearing assembly, and the second mounting plate can also support the rotating shaft assembly via the second bearing assembly.

[0013] In addition, the first mounting plate and the second mounting plate are spaced apart from each other so that there is a certain distance between the first bearing assembly and the second bearing assembly. That is, there is a certain distance between the support of the first mounting plate on the rotating shaft assembly and the support of the second mounting plate on the rotating shaft assembly. This reduces the possibility of excessive torque and shaking during the operation of the rotating shaft assembly and improves the stability of the rotating connection mechanism during operation.

[0022] With the above structure, one side of the first reinforcing plate is connected to the first protrusion, and the other adjacent side of the first reinforcing plate is connected to the first support plate; so that the connection between the first mounting plate and the first support plate is more secure, and the possibility of the first mounting plate wobbling relative to the first support plate during the operation of the rotating connection mechanism is reduced.

[0023] In addition, one side of the second reinforcing plate is connected to the second protrusion, and the other adjacent side of the second reinforcing plate is connected to the second support plate; so that the connection between the first mounting plate and the second support plate is more secure, reducing the possibility of the first mounting plate wobbling relative to the second support plate during the operation of the rotating connection mechanism.

[0024] In some embodiments, the first bearing assembly includes a first bearing bracket and a first bearing member. The first bearing bracket is fixed to the side of the first mounting plate facing away from the second mounting plate, the first bearing member is installed inside the first bearing bracket, and the rotating shaft assembly is rotatably connected to the first bearing bracket via the first bearing member.

The second bearing component 36 can be installed in the mounting space, and the second bearing bracket 42 can be fixed to the second mounting plate 12 by threaded connection or welding.

[0085] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the rotating connection mechanism 100 in any of the above embodiments. The fruit and vegetable sorting device may further include a frame, a rotating frame, and multiple fruit and vegetable gripping mechanisms. The mounting frame 10 may be fixed to the frame, the rotating frame may be fixed to the rotating shaft assembly 20, and all fruit and vegetable gripping mechanisms may be mounted on the rotating frame, with all fruit and vegetable gripping mechanisms evenly distributed around the circumference of the rotating frame. The motor may drive the rotating frame to rotate relative to the frame via the rotating shaft assembly 20, thereby driving all fruit and vegetable gripping mechanisms to perform circular motion. The fruit and vegetable gripping mechanisms may pick up fruits and vegetables located at one location in the fruit and vegetable sorting device and move them to another location in the fruit and vegetable sorting device.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
