Detailed Description

The technical solution in the embodiments of the present patent will be clearly and completely described below with reference to the drawings in the embodiments of the present patent.

Referring to fig. 1, the automatic blueberry equal-dividing device comprises a conveying belt 1, two pairs of dividing plates 2, a camera 3, two substantially parallel translation rails 4, two pushing nozzles 5, a defective product collecting device 6, a defective product conveying belt 7, an equal-dividing rail 8, a collecting device (comprising a first-stage collecting device 91, a second-stage collecting device 92, a third-stage collecting device 93 and a fourth-stage collecting device 94), a conveying belt (comprising a first-stage conveying belt 101, a second-stage conveying belt 102, a third-stage conveying belt 103 and a fourth-stage conveying belt 104) and a buffer film 11.

referring to fig. 2, the mechanically harvested blueberries which are well-done and well-mixed are conveyed by a conveying belt 1, two pairs of splitter plates 2 are arranged at the tail part of the conveying belt 1 to divide the mixed blueberries of the conveying belt 1 into two parts, and two horizontal translation rails 4 are respectively arranged at the outlets of the two pairs of splitter plates 2 to enable the outlets and the inlets to be in butt joint. The camera 3 is arranged above the translation track 4 and used for acquiring blueberry photo information on the translation track, the controller obtains the blueberry position with abnormal color and the blueberry position with abnormal gray value by processing the blueberry photo information, when the abnormal flawed blueberries move to the position near the push-out nozzle 5, the controller controls the corresponding electromagnetic valve to act, so that the push-out nozzle 5 arranged at the side part of the translation track blows high-pressure gas out of the translation track, the abnormal blueberries are blown out of the translation track and fall onto a defective product collecting device 6 below the translation track, after the defective product collecting device 6 is fully collected, the defective product is conveyed away by a defective product conveying belt 7, and a new defective product collecting device 6 is conveyed to fill up vacant positions. The rest blueberries enter the grading track 8, and the grading track 8 is provided with four sides 81, 82, 83 and 84 forming a quadrilateral; wherein, the first, second and third edges are respectively provided with primary, secondary and tertiary notches 85, 86 and 87 with the widths of 12mm, 16mm and 20 mm.

referring to fig. 3-6, first, second and third grade collecting devices 91, 92 and 93 are respectively arranged below the first, second and third grade grading notches 85, 86 and 87, and a fourth grade collecting device 94 is arranged below the outlet of the grading track 8. The first-stage, second-stage, third-stage and fourth-stage collecting devices 91, 92, 93 and 94 are all arranged on corresponding first-stage, second-stage, third-stage and fourth-stage conveyor belts 101, 102, 103 and 104, and the first-stage, second-stage, third-stage and fourth-stage conveyor belts 101, 102, 103 and 104 can respectively drive the first-stage, second-stage, third-stage and fourth-stage collecting devices 91, 92, 93 and 94 to move, which belongs to the prior art and is not described again. In order to prevent the first-stage, second-stage, third-stage, and fourth-stage conveyor belts 101, 102, 103, 104 from spatially interfering, the first-stage, third-stage conveyor belts 101, 103 are arranged above the second-stage, fourth-stage conveyor belts 102, 104. Because the outlets of the four levels of the grading tracks are respectively positioned in different spatial directions, the conveyor belts are arranged in a three-dimensional manner, the three-dimensional space below the grading tracks is fully utilized, and the production line is compact. Through installing the roller between two conveyer belts, carry empty collection device from a conveyer belt on another conveyer belt, the collection device who fills with the blueberry leaves through the conveyer belt is carried, and the conveyer belt carries the blueberry with the collection device on the roller and collects the position simultaneously, and this process realizes that the degree of difficulty is low for automation, and the automated process is comparatively reliable.

When the blueberries pass through the first-grade grading notches, the blueberries with the diameters smaller than 12mm are screened out (fall from the first-grade grading notches), and the rest of the blueberries continue to roll; screening the blueberries with the diameter smaller than 16mm through the secondary equal-dividing notches (dropping from the secondary equal-dividing notches), and continuously rolling the rest blueberries; the blueberries with the diameter smaller than 20mm are screened out through the three-level grading notches, and the rest of the blueberries continue to roll and are graded out of the outlets at the tail parts of the tracks to serve as fourth-level blueberries. Every grade of constant notch is connected with the buffering film, and the blueberry falls into corresponding collection device gently along the buffering of film through the buffering film, guarantees that the blueberry can not be because of dropping fast and damaged.

The dividing track 4 is provided with a certain oblique angle (high inlet and low outlet) in space, blueberries are driven to roll by gravity, the outlets of the blueberries are arranged at 4 positions in space and are not interfered with each other, and space three-dimensional conveying belts (comprising rollers) and other transportation and collection devices are adopted.

The automatic blueberry grading device can be used on a production line and also can be directly installed on a vehicle-mounted system, the size of the automatic blueberry grading device is flexible, and the size can be updated according to the actual situation.
