Classification and grading device for red date sorting machine

Abstract

The invention discloses a classification and grading device for a red date sorting machine. The classification and grading device for the red date sorting machine is composed of a slide groove, a dispersion box, a V-shaped frame, a first stepper motor, a conveying belt, a controller, a classification device, a roller, an inferior-quality product box and a grading device, wherein the slide groove is used for receiving red dates scattered from a vibration mechanism; the dispersion box is used for conveying the red dates in the slide groove onto the V-shaped frame; the V-shaped frame is used forreceiving the red dates conveyed from the dispersion box; the conveying belt is driven to move by the first stepper motor, and then the V-shaped frame is driven to move; the red dates on the conveyingbelt and in the V-shaped frame are graded by the grading device; the graded red dates are transferred to the classification device; the red dates are classified by the classification device; the reddates which do not enter the classification device, in the V-shaped frame, fall into the inferior-quality product box along with the conveying belt to be stored; and the controller is used for controlling the first stepper motor to drive the conveying belt to move, and controlling the classification device and the grading device to classify and grade the red dates separately.

Description

technical field [0001] The invention relates to the field of classification and grading of jujubes, in particular to a classification and grading device for jujube sorting machines. Background technique [0002] Jujube belongs to the plant of Angiosperm, Dicotyledoneae, Rhamnoles, Rhamnaceae, and Jujube. Its vitamin content is very high, and it has the reputation of "natural vitamin pill", which has the effects of nourishing yin and yang, and nourishing blood. Among them, red dates are divided into four categories: finished products, meat dates, skin dates, and defective products, and then finished products, meat dates, and skin dates are divided into four grades: special grade, first grade, second grade, and third grade. The red dates blown out by the gas blowing device are graded and packaged. Jujubes need to be sorted after being picked. However, the cost of manual sorting is very high, so a jujube sorting machine has appeared. The jujube sorting process of jujube sorti...

Problems solved by technology

[0004] However, when jujubes enter step 5 for sorting, only the grades of jujubes can be sorted out, and its type cannot be sorted; at the same time, when shooting, the camera can only take pictures of one side of the jujubes, and the overall quality of the jujubes cannot be compared. The judgment is not perfect, so the shooting is not comprehensive, and it is not completely accurate only through data processing on one side; when the conveyor belt transports red dates to the camera for image collection, red dates are prone to overlap, which leads to misjudgment of overlapping red dates on the PC side For one, making the false detection rate extremely high

In addition, jujubes are divided into finished jujubes, skinned jujubes and fleshy jujubes according to their plumpness and hardness. It is inaccurate to classify jujubes only by size.
