Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fruit and vegetable processing, and more specifically, to an anti-collision mechanism for fruit and vegetable sorting. Background Art
[0002] When processing fruits and vegetables, it is necessary to select them according to their size, weight, color, etc., and select fruits and vegetables that meet compound production needs for processing. Compared with inefficient manual operations by workers, more and more factories will use automated sorting equipment to efficiently sort fruits and vegetables to meet usage needs.
[0003] During sorting, common size sorting mechanisms are generally operated through mesh rollers with sieves. While transporting fruits and vegetables, fruits and vegetables of complex sizes fall into the mesh rollers from the sieves. Generally, multiple sieves are set on the mesh rollers for the entry of complex-adjusted fruits and vegetables. After entering the mesh rollers, the fruits and vegetables are affected by the rotation of the mesh rollers and move, and collide with the mesh rollers and other fruits and vegetables, which affects the quality of the fruits and vegetables. Moreover, after sorting, common sorting mechanisms move the fruits and vegetables to separate transmission equipment. In order to avoid interference between equipment, a certain distance and height difference are left between common transmission equipment and sorting structures. The sorted fruits and vegetables fall into or roll into the transmission equipment. The potential energy change during movement causes a certain impact force on the fruits and vegetables, which collides with the transmission equipment when in contact, resulting in damage to the fruits and vegetables, affecting the quality of the fruits and vegetables. In addition, common sorting structures sort multiple fruits and vegetables at one time, and the fruits and vegetables are easily affected by each other, resulting in inaccurate sorting, and collisions that cause damage to the fruits and vegetables.

[0031] See also Figure 1-5 A fruit and vegetable sorting anti-collision mechanism comprises a frame 1, a conveyor belt 2 is arranged on the frame 1, a screening roller 3 is arranged at one end of the conveyor belt 2, the screening roller 3 is rotatably matched with the frame 1, a screening port 4 is opened on the screening roller 3, a plurality of screening rollers 3 are provided, and the screening ports 4 on each screening roller 3 are of different sizes and are arranged in order from small to large, a guide tube 5 is arranged inside the screening roller 3, and the guide tube 5 is matched with the screening port 4;
[0032] A delivery belt 6 is provided at the lower end of the screening roller 3, and multiple groups of transmission belts are provided to cooperate with the screening roller 3. The frame 1 is provided with a first buffer plate 7 and a second buffer plate 8 between the delivery belt 6 and the screening roller 3. Multiple first buffer plates 7 and second buffer plates 8 are arranged to be tilted downward and are staggered.
[0033] In this embodiment, when the equipment is working, under the support of the frame 1, the fruits and vegetables are transported to the sorting structure through the conveyor belt 2, so that the fruits and vegetables are moved to the sorting structure composed of multiple screening rollers 3. The screening rollers 3 rotate, which will drive the fruits and vegetables to move. Among them, the size of the composite screening port 4, the fruits and vegetables smaller than the screening port 4 will fall into the screening port 4, move along the guide tube 5, and flow out from the screening port 4 at the other end, thereby moving to the bottom of the screening roller 3, and the fruits and vegetables larger than the screening port 4 will move to the next screening roller 3 for the next sorting, so that fruits and vegetables of different sizes can be sorted out, and through the cooperation of the screening port 4 and the guide tube 5 structure, when sorting fruits and vegetables, each fruit and vegetable will be sorted independently, and will not stick together and collide, thereby ensuring the safety of fruits and vegetables during sorting.
[0034] More specifically, when the sorted fruits and vegetables leave the screening roller 3 and move downward, they will fall onto the first buffer plate 7, roll along the first buffer plate 7, and then fall onto the second buffer plate 8 and continue to move. After being guided by multiple groups of first buffer plates 7 and second buffer plates 8 in sequence, they fall onto the outgoing belt 6. The impact generated by the falling of fruits and vegetables is absorbed through the cooperation of the relatively relaxed first buffer plates 7 and second buffer plates 8. The guidance of the first buffer plates 7 and the second buffer plates 8 forces the fruits and vegetables to continuously change their moving direction, thereby reducing the potential energy stored in the fruits and vegetables when they move in one direction.
[0035] See also Figure 1As an implementation method of guiding: support rods 9 are provided at both ends of the conveyor belt 2, and multiple support rods 9 are provided. Guide plates 10 are provided on the support rods 9, and the guide plates 10 cooperate with the screening rollers 3.
[0036] Specifically, under the support of multiple groups of support rods 9, the guide plates 10 are used for guidance. When the fruits and vegetables move, the guide plates 10 contact the fruits and vegetables to adjust the moving direction of the fruits and vegetables, and finally arrange the fruits and vegetables in a straight line, so that each fruit and vegetable can be sorted separately, avoiding collision when multiple fruits and vegetables are sorted together.
[0037] Please refer to Figure 1 As a further implementation of the guide plate 10 : a protective cover 11 is provided on the guide plate 10 .
[0038] Specifically, the guide plate 10 contacts the fruits and vegetables through the protective cover 11 to prevent the fruits and vegetables from shrinking when the moving direction is adjusted.
[0039] Please refer to Figure 4 As a further implementation of the screening port 4: a guide port 12 is provided at the outer end of the screening port 4, and the diameter of the screening port 4 gradually decreases from the outside to the inside.
[0040] Specifically, by contacting the guide opening 12 with the fruits and vegetables, the fruits and vegetables can be more easily moved to the screening opening 4 for sorting.
[0041] Please refer to Figure 3-Figure 5 As a further implementation of the screening roller 3: a guide column 13 is provided on the frame 1, a matching groove 14 is opened at one end of the screening roller 3, the matching groove 14 matches with the guide column 13, and a passing port 15 is opened on the guide column 13, and the passing port 15 matches with the guide tube 5.
[0042] Specifically, when the fruits and vegetables move along the guide tube 5, only the guide tube 5 aligned with the passage opening 15 can be connected to the guide tube 5 on the opposite side, so that the fruits and vegetables move through the passage opening 15, and the fruits and vegetables in the remaining guide tubes 5 will be blocked by the guide column 13 to avoid collision between the fruits and vegetables in the same screening roller 3.
[0043] Please refer to Figure 1-Figure 3 As a further implementation of the screening roller 3: a mounting groove 16 is opened at one end of the frame 1, a mounting block 17 is arranged in the mounting groove 16, the mounting block 17 is detachably connected to the mounting groove 16, and the guide column 13 is arranged on the mounting block 17.
[0044] Specifically, the mounting block 17 can be removed from the mounting groove 16 to expose space at one end of the frame 1, thereby removing the guide column 13 and the screening roller 3, and replacing the screening roller 3 with a screening port 4 of a size that meets the sorting requirements.
[0045] Please refer to Figure 2 and Figure 6As a further implementation of the screening roller 3: a driving shaft 18 is provided at one end of the frame 1 away from the mounting groove 16, and an axis groove 19 is opened at one end of the screening roller 3, and the driving shaft 18 cooperates with the axis groove 19.
[0046] Specifically, when installing the screening roller 3, the driving shaft 18 is installed in the shaft groove 19. When the equipment is working, the screening roller 3 is driven to rotate through the cooperation between the driving shaft 18 and the shaft groove 19.
[0047] Please refer to Figure 2 As a further implementation of the buffer plate: a buffer pad 20 is provided on both the first buffer plate 7 and the second buffer plate 8.
[0048] Specifically, the cushion pad 20 provides a cushioning effect to reduce the impact generated when falling.
[0049] In summary, when the overall equipment is in use (or running):
[0050] When the equipment is in use, the mounting block 17 is removed from the mounting groove 16 to expose space at one end of the frame 1, so as to install the guide column 13 and the screening roller 3. According to the sorting requirements, the screening roller 3 with the size of the screening port 4 that meets the requirements is replaced. When installing the screening roller 3, the drive shaft 18 is installed in the shaft groove 19, and then the mounting block 17 is installed, and the guide column 13 is inserted into the matching groove 14. When the equipment is working, under the support of the frame 1, the equipment is connected to the external power supply, and the fruits and vegetables are transported to the sorting structure through the conveyor belt 2. Under the support of multiple groups of support rods 9, the guide plate 10 is used for guidance. When the fruits and vegetables move, the guide plate 10 contacts the fruits and vegetables through the protective cover 11 to avoid the fruits and vegetables from shrinking when adjusting the moving direction. Finally, the fruits and vegetables are arranged in a straight line, so that each fruit and vegetable is sorted separately, and collision is avoided when multiple fruits and vegetables are sorted together. The fruits and vegetables are moved to the sorting structure composed of multiple screening rollers 3. Under the drive of the drive shaft 18, the drive shaft 18 is matched with the shaft groove 19 to drive the sorting structure. The rotation of the screening roller 3 will drive the movement of fruits and vegetables, and the fruits and vegetables will contact with the fruits and vegetables through the guide port 12, so that the fruits and vegetables can be moved to the screening port 4 more easily for sorting operation. Among them, the size of the composite screening port 4, the fruits and vegetables smaller than the screening port 4 will fall into the screening port 4, move along the guide tube 5, and flow out from the screening port 4 at the other end, thereby moving to the bottom of the screening roller 3, and the fruits and vegetables larger than the screening port 4 will move to the next screening roller 3 for the next sorting, so that fruits and vegetables of different sizes are sorted out and guided to different conveyor belts 6 for transportation. In addition, through the coordination of the screening port 4 and the guide tube 5 structure, when sorting fruits and vegetables, each fruit and vegetable will be sorted independently and will not collide with each other, and when the fruits and vegetables move along the guide tube 5, only the guide tube 5 aligned with the object port 15 can be connected to the guide tube 5 on the opposite side, so that the fruits and vegetables move through the object port 15, and the fruits and vegetables in the remaining guide tubes 5 will be blocked by the guide column 13, so as to avoid the collision of fruits and vegetables in the same screening roller 3, thereby ensuring the safety of fruits and vegetables during sorting.
[0051] When the sorted fruits and vegetables leave the screening roller 3 and move downward, they will fall onto the first buffer plate 7, roll along the first buffer plate 7, and then fall onto the second buffer plate 8 and continue to move. After being guided by multiple groups of first buffer plates 7 and second buffer plates 8 in sequence, they fall onto the outgoing belt 6. The first buffer plate 7 and the second buffer plate 8 cooperate with each other to absorb the impact generated when the fruits and vegetables fall. The guidance of the first buffer plate 7 and the second buffer plate 8 forces the fruits and vegetables to constantly change their moving direction, reducing the potential energy stored in the fruits and vegetables when they move in one direction. The first buffer plate 7 and the second buffer plate 8 both provide a buffering effect through the buffer pad 20, reducing the impact generated when the fruits and vegetables fall.
[0052] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
