Description

Technical Field

[0001] This utility model belongs to the field of sorting device technology, specifically a multi-stage fruit and vegetable sorting device based on self-adjustment of aperture and slope. Background Technology

[0002] Multi-stage fruit and vegetable sorting devices based on self-adjusting aperture and slope have developed into a mature technology and play an important role in the fruit and vegetable industry. Their maturity is reflected in their effective solution to the pain points of traditional sorting and their wide application results.

[0003] Current multi-stage fruit and vegetable sorting devices based on aperture and slope self-adjustment typically consist of a sorting base, multiple sets of inclined conveyor belts mounted on the sorting base, partition plates and guide plates fixedly connected to the bottom wall of the sorting base, and sorting ports opened on one side of the sorting base. When sorting smaller fruits and vegetables such as cherries, blueberries, tree strawberries, and cherry tomatoes, the fruits and vegetables are placed between the inclined conveyor belts. The spacing between the multiple conveyor belts is the same at one end, but the spacing gradually increases at the other end, realizing automatic sorting of small fruits and vegetables. With the cooperation of the partition plates and guide plates, the small fruits and vegetables sorted into different sizes are discharged from different sorting ports and fall into the collection box placed on one side of the sorting base.

[0004] However, with this sorting method, after sorting fruits and vegetables into different collection boxes, the sorting process usually needs to be stopped when the collection boxes need to be replaced. Otherwise, during the interval between changing collection boxes, fruits and vegetables that are still being sorted will continuously be discharged from the sorting port. Since there are no collection boxes to collect them at this time, the fruits and vegetables are prone to falling and getting damaged. Smaller fruits and vegetables are also smaller in size, and if they are manually removed from the collection boxes and transferred, the efficiency is low. Therefore, to address the above problems, a multi-stage fruit and vegetable sorting device based on self-adjusting aperture and slope is proposed. Utility Model Content

The spacing between the sorting racks 3 gradually increases, so as to facilitate the automatic sorting of small fruits and vegetables of different sizes. At the same time, four sorting ports are opened on one side of the sorting seat 1. The above structure constitutes the multi-stage fruit and vegetable sorting device based on self-adjustment of aperture and slope in the prior art. This utility model adds the following structure to the above: The sorting station 1 is provided with a material handling mechanism 7. The material handling mechanism 7 includes four equally spaced fixed plates 71 fixedly connected to one side of the sorting station 1. The fixed plates 71 are on the same side as the sorting plates. A U-shaped placement frame 72 is slidably connected to the top of the fixed plates 71. Four equally spaced fixed frames 75 are fixedly connected to one side of the sorting station 1 near the fixed plates 71. A rectangular feeding plate 73 is rotatably connected to one side of the inner wall of the fixed frame 75 through a rotating shaft. A feeding groove 74 is opened on the top of the feeding plate 73. By setting up the material handling mechanism 7, it is easy to block the sorting port when changing the collection box, and the inclined feeding plate 73 can be used to limit the movement of small fruits and vegetables, so as to prevent the fruits and vegetables from falling when changing the collection box. The other end of the feeding plate 73 is fixedly connected to a transmission rod 8. The other end of the transmission rod 8 passes through the fixed frame 75 and is fixedly connected to a gear 9. The top of the fixed frame 75 is fixedly connected to an L-shaped limiting frame 10. The inner top wall of the limiting frame 10 is fixedly connected to a rectangular positioning rod. The outer wall of the positioning rod is slidably connected to a rack 11. The top of the rack 11 is provided with a rectangular groove that matches the positioning rod. The rack 11 is meshed with the gear 9. The bottom of the rack 11 is fixedly connected to a pressing block 12 with a tapered bottom. The tapered surface of the pressing block 12 faces the placement frame 72. By setting up the transmission rod 8, gear 9, rack 11 and limit frame 10, the material feeding plate 73 can be automatically flipped during the process of changing the collection box, simplifying the operation steps. A spring 13 is sleeved on the outer wall of the positioning rod. The spring 13 is located at the upper end of the rack 11. A wear-resistant layer is provided on the outer wall of the pressing block 12. The setting of the spring 13 can facilitate the rack 11 to reset quickly and strengthen the number of small fruits and vegetables that the feeding plate 73 can limit, so as to prevent too many small fruits and vegetables from impacting the feeding plate 73 open. A rectangular guide plate 14 is fixedly connected to the top of the fixed plate 71, and a rectangular guide groove adapted to the guide plate 14 is provided at the bottom of the placement frame 72. The guide plate 14 and the guide groove are provided to assist in the movement and limiting of the placement plate.

[0019] The inner bottom wall of the placement rack 72 has two symmetrically distributed rectangular actuation grooves 15. The outer wall of the placement rack 72 is provided with a wear-resistant layer. The actuation grooves 15 make it easy to apply pressure and actuation force to the collection box from bottom to top by placing a hand into the actuation grooves 15.

[0020] An auxiliary groove is provided on the top of the fixed plate 71. An auxiliary roller 16 is rotatably connected to the inner side wall of the auxiliary groove via a rotating shaft. The auxiliary roller 16 abuts against the bottom of the placement frame 72. The auxiliary groove and the auxiliary roller 16 can help reduce the resistance when pulling the placement plate.

[0021] The inner wall of the feeding trough 74 is equipped with rubber pads to improve the protection of fruits and vegetables, and the outer wall of the conveyor belt 4 is equipped with rubber pads to improve the protection of fruits and vegetables.

[0022] Based on the above structure, the present invention includes the following implementation process: The external collection box is placed in the center of the placement frame 72 beforehand, and the placement frame 72 is pushed towards the sorting seat 1. During this process, one end of the placement frame 72 contacts the pressing block 12 and applies pressure to the pressing block 12, so that the conical pressing block 12 is pressed and drives the rack 11 to move upward. The rack 11 drives the gear 9 to rotate, and the gear 9 drives the feeding plate 73 to rotate through the transmission rod 8, so that the feeding plate 73 that closes the sorting port rotates 90-150 degrees, which can be set according to the actual situation. The feeding plate 73 unfolds until one end of the placement frame 72 is in contact with the sorting seat 1. At this time, the bottom end of the pressing block 12 abuts against the top end of the placement frame 72. Small fruits and vegetables are placed on multiple sorting racks 3 and multiple conveyor belts 4 are driven to move the small fruits and vegetables to the other end. During this process, the gap between the multiple conveyor belts 4 gradually increases to complete the sorting of small fruits and vegetables of different sizes. After sorting, the small fruits and vegetables pass through the conveyor belts 4 and fall onto the guide plate 5. The separator plate 6 separates the sorted fruits and vegetables. Then the sorted fruits and vegetables pass through the sorting port and fall onto the discharge plate 73 and onto the collection box. When a certain number of small fruits and vegetables have been collected in the collection box, and the collection box needs to be replaced, the corresponding placement rack 72 can be pulled directly to move the placement rack 72 and the collection box away from the sorting seat 1. During this process, the pressure on the pressing block 12 disappears. Under the pressure of the spring 13, the rack 11 and the pressing block 12 descend, and the gear 9 drives the feeding plate 73 to flip through the transmission rod 8, so that the inclined feeding plate 73 flips to fit against the sorting seat 1, that is, the opening of the feeding trough 74 faces the sorting seat 1. Under the pressure of the spring 13, the feeding plate 73 can stably block the sorting port. The collection box is removed and replaced with a new collection box that has not been filled with fruits and vegetables. The placement rack 72 is pushed towards the sorting seat 1 again. During this process, one end of the placement rack 72 contacts the pressing block 12 and applies pressure to the pressing block 12, so that the conical pressing block 12 is pressed and drives the rack 11 to move upward. The rack 11 drives the gear 9 to rotate. The gear 9 drives the feeding plate 73 to rotate through the transmission rod 8, so that the feeding plate 73 that closes the sorting port rotates 90-150 degrees. The specific setting can be set according to the actual situation. The feeding plate 73 unfolds until one end of the placement rack 72 is in contact with the sorting seat 1. At this time, the bottom end of the pressing block 12 abuts against the top end of the placement rack 72. Repeat the above steps to continuously sort and pick up and put away small fruits and vegetables.
