Granular material automatic grading method and device

Abstract

The invention discloses an automatic grading method for particulate material and a device thereof. A circular disc which is provided with equant grooves on the same circumference at the periphery is coaxially connected with an motor, the circular disc is arranged inside a baffle ring and has an angle of 20-30 degrees with the horizontal plane, a grading execution area at a lower end of the baffle ring is provided with a plurality of gaps which are equally spaced with gaps of the circular disc, a spring hinge is arranged at each gap, one end of a discharge gate of each grade is articulated with the spring hinge thereof, the other end of discharge gate of each grade is connected with an electromagnetic device thereof, a camera is arranged vertically over a level high position of the circular disc, and a PC is electrically connected with the motor, the camera and the electromagnetic device respectively. With regard to the particulate material which is formed into single particulate distribution and is spirally conveyed in the spaced grooves at the edge of the inclined disc and is provided with grading information, the device automatically controls the opening of the discharge gate of the corresponding grade by magnetic force at the grading execution area so as to discharge the material under the action of the centrifugal inertia and gravity, which realizes the quick and exact execution and automatic control of discharge of the particulate material particle by particle.

Description

technical field [0001] The invention relates to the technology of automatic classification of materials, in particular to a method and device for automatic classification of granular materials. Background technique [0002] In various fields such as industry, agriculture, and medicine, detection and automatic classification technologies for granular materials are needed. Most of the existing granular material classification mechanisms are pneumatic and robotic. The pneumatic type uses air force to blow the granular materials out of the grading mechanism. Since the performance indicators such as the response speed of the pneumatic system used have a great influence on the classification accuracy, the cost is high, especially for the pneumatic grading effect of the granular materials. The dialing type has better accuracy, but it is more difficult to achieve fast classification, that is to say, the speed of the swinging back and forth of the robot hand cannot keep up with the ...

Problems solved by technology

The pneumatic type uses air force to blow the granular materials out of the grading mechanism. Since the performance indicators such as the response speed of the pneumatic system used have a great influence on the classification accuracy, the cost is high, especially for the pneumatic grading effect of the granular materials. The dialing type has better accuracy, but it is more difficult to achieve fast classification, that is to say, the speed of the swinging back and forth of the robot hand cannot keep up with the speed of the granular material passing the robot hand when the disc rotates. high cost

The lack of existing technology makes a large number of granular material classification work in various industries still rely on manual work
