[0002] With the development of economy, people's living standards are constantly improving, and the demand for high-quality fruits and vegetables is also growing. This phenomenon has promoted the continuous progress of mechanized grading technology of fruits and vegetables after harvest. Among them, the fruit and vegetable sorting and conveying device plays a vital step in the process of realizing mechanized grading of fruits and vegetables after harvest. The existing fruit and vegetable sorting and conveying device controls the movement of the roller by the motor installed on the motor support frame during operation. The three motors are respectively installed on the front half and the back half of the conveying device and the reflux device. By controlling the power on and off of the two motors on the conveying device, the start and stop status of the roller in the corresponding area can be triggered. When the back half of the conveying device stops for taking the fruit, the front half of the conveying device is still in operation. After taking the fruit, the motor of the back half of the conveying device is energized. The empty fruit cup after taking the fruit is transferred to the reflux device under the action of the guide assembly at the turning point.

[0029] The present embodiment provides a sorting machine, which is mainly used for screening and sorting fruits and vegetables. In order to solve the shortcomings of the existing sorting machines with complex structures and high costs, the present embodiment provides a conveying device for the sorting machine, which is specifically as follows.

[0030] like Figure 1The present embodiment provides a conveying device for a sorting machine, comprising a frame 10, a conveying belt 20, a return belt 30, a guide assembly 40 and a driving device 50. The conveying belt 20, the return belt 30 and the guide assembly 40 are all arranged on the frame 10. The guide assembly 40 is used to guide the fruit cups at the output end of the conveying belt 20 to the input end of the return belt 30. The driving device 50 is arranged on the frame 10 and connected with the conveying belt 20 and the return belt 30. The driving device 50 drives the conveying belt 20 and the return belt 30 to rotate along a first direction 70 and a second direction 80 respectively. In detail, the conveying device for a sorting machine provided in the present embodiment is provided with two conveying belts 20 and two return belts 30. The two conveying belts 20 correspond to the two return belts 30 one by one and are symmetrically arranged on the frame 10. In addition, the first direction 70 and the second direction 80 in the present embodiment can be parallel and opposite, or can be at an angle of a certain angle, which is not limited in the present embodiment and can be determined according to the situation.

[0031] It can be understood that in this embodiment, a driving device 50 is used to drive the conveyor belt 20 and the return belt 30 to operate in different directions. The single power drive saves costs and the overall structure is simple. In addition, after the fruits and vegetables are taken from the conveyor belt 20, the remaining fruit cups pass through the guide assembly 40 and enter the return belt 30 to achieve the return of the empty fruit cups.

[0032] like Figure 2 As shown, in a preferred embodiment, the frame 10 includes a conveying plate 11, a side plate 12 and a support frame 13, the support frame 13 is arranged on the bottom surface of the conveying plate 11, the side plate 12 is connected to the side of one end of the conveying plate 11, the conveying belt 20 is arranged on the conveying plate 11, the return belt 30 is arranged on the side plate 12, the guide assembly 40 is arranged at one end of the conveying plate 11 connected to the side plate 12, and the driving device 50 is arranged on the support frame 13. In detail, an isolation strip 112 is arranged in the middle of the conveying plate 11, dividing the conveying plate 11 into two symmetrical conveying channels, the two conveying belts 20 are respectively arranged in the two conveying channels, and the side plate 12 is also provided with two, which are respectively located on both sides of the conveying plate 11, and the two return belts 30 are respectively arranged on the two side plates 12.

[0033] It can be understood that the isolation strip 112 and the conveying plate 11 are connected by bolts for easy disassembly, and the side plate 12 and the conveying plate 11 are also connected by bolts for easy disassembly and maintenance.

[0034] In a preferred embodiment, an output notch 111 is provided at the connection between the conveying plate 11 and the side plate 12, and the output notch 111 connects the output end of the conveying belt 20 and the input end of the return belt 30. In detail, the purpose of providing the output notch 111 is to facilitate the empty fruit cups at the output end of the conveying belt 20 to enter the input end of the return belt 30, and the size of the output notch 111 is approximately equal to the diameter of 1 to 3 fruit cups, and the specific amount depends on the situation.

[0035] In a preferred embodiment, the guide assembly 40 includes a guide plate 41, which is disposed at one end of the conveying plate 11 connected to the side plate 12, and has an arc-shaped curve on the guide plate 41, which is located above the output end of the conveying belt 20. In detail, the guide plate 41 is connected to the isolation strip 112 by bolts, and when the empty fruit cups on the conveying belt 20 pass through the guide plate 41, the movement direction of the empty fruit cups is shifted due to the effect of the arc-shaped curve, and then moves to the input end of the return belt 30. It can be understood that the setting of the arc-shaped curve can smoothly change the movement direction of the fruit cups and avoid the occurrence of fruit cup blockage.

[0036] In a preferred embodiment, the guide assembly 40 further includes a guide wheel 42, which is disposed on the conveying plate 11 and located at the output gap 111. It is understandable that in actual operation, when the empty fruit cup passes through the output gap 111, due to the provision of the guide wheel 42, the empty fruit cup passes through the output gap 111 more quickly after contacting the guide wheel 42. Therefore, the purpose of providing the guide wheel 42 in this embodiment is to prevent the empty fruit cup from blocking the output gap 111.

[0037] In a preferred embodiment, the driving device 50 includes a motor 52 and a transmission shaft 51, both of which are arranged on the support frame 13. The motor 52 drives the transmission shaft 51 to rotate. The middle part of the transmission shaft 51 is connected to the conveying belt 20, and the end part is connected to the return belt 30.

[0038] In detail, since the conveying directions of the conveyor belt 20 and the return belt 30 of this embodiment are parallel and opposite, the direction of the transmission shaft 51 is perpendicular to the conveying directions of the conveyor belt 20 and the return belt 30. During operation, the motor 52 drives the transmission shaft 51 to rotate. Since the lower end of the conveyor belt 20 is tightly attached to the transmission shaft 51 under the action of the support frame 13, the lower end of the conveyor belt 20 runs in the same direction as the transmission shaft 51 due to the friction force, and the upper end of the conveyor belt 20 can run in the opposite direction to transport the sorted fruits and vegetables to the output end; and the end of the return belt 30 is connected to the transmission shaft 51, and the movement direction is consistent with that of the transmission shaft 51.

[0039] In a preferred embodiment, the input end of the return belt 30 is higher than the output end. It is understandable that the return belt 30 has a certain inclination angle, and when the empty fruit cups are transferred to the return belt 30, they can move downward under the drive of the return belt 30 and the action of gravity to prevent the fruit cups from being blocked on the return belt 30.

[0040] In a preferred embodiment, the conveying device of the sorting machine further includes a plurality of rollers 60 arranged on the side plate 12, and the plurality of rollers 60 are arranged side by side along the conveying direction of the return belt 30 and are located behind the output end of the return belt 30. In detail, the plurality of rollers 60 arranged side by side have a certain angle on the horizontal plane, so that the empty fruit cups can slide under the action of gravity and inertia.

[0041] The conveying device of the separator provided in this embodiment has the following advantages:

[0042] In this embodiment, the left and right sides are symmetrically distributed, and the conveyor belt 20 and the return belt 30 realize torque conversion through a transmission shaft 51. The output ends of the two groups of conveyor belts 20 are provided with guide assemblies 40, and the ends of the two groups of return belts 30 are fixedly installed with unpowered rollers 60. The lower ends of the two groups of conveyor belts 20 are installed with support frames 13. The lower ends of the conveyor belts 20 are closely attached to the transmission shaft 51 under the action of the support frame 13. During operation, the transmission shaft 51 starts to rotate under the drive of the motor 52. The lower end of the conveyor belt 20 rotates in the same direction as the transmission shaft 51 under the action of friction, and the upper end of the conveyor belt 20 runs in the opposite direction; the end of the return belt 30 is connected to the transmission shaft 51, and is consistent with the direction of the transmission shaft 51. The sorted fruits and vegetables enter the return belt 30 through the conveyor belt 20 and the guide assembly 40. Since the return belt 30 has a certain inclination angle, the empty fruit cup after taking the fruit enters the next stage through the unpowered roller 60 under the action of gravity and inertia, realizing the fruit taking of the fruits and vegetables after sorting and the return function of the empty fruit cup.

[0043] In this embodiment, a driving device 50 drives the conveyor belt 20 and the return belt 30 to operate in different directions. The single power drive saves costs and the overall structure is simple. In addition, after the fruits and vegetables are taken from the conveyor belt 20, the remaining fruit cups pass through the guide assembly 40 and enter the return belt 30 to achieve the return of the empty fruit cups.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
