Dual-time judgement electromagnetic propulsion type fruit grading device

Abstract

The invention discloses a dual-time judgement electromagnetic propulsion type fruit grading device. The device comprises a fruit conveying rail. The fruit conveying rail is provided with an arc-shapeddownward sliding segment and a horizontal sliding rail segment. A stress sensor is vertically arranged on the end face of the tail end of the horizontal sliding rail segment. A blocking and pushing plate which is vertically arranged is connected with the back side of the stress sensor. Stepping motors are connected with both the two sides of the blocking and pushing plate, and are used for controlling the blocking and pushing plate to rotate for 360 degrees in the falling direction of fruits. A conveyer belt is arranged on one side of the blocking and pushing plate and corresponds to the horizontal sliding rail segment. A laser emission device and a laser receiving device are arranged on the two sides of the end face of the end, close to the blocking and pushing plate, of the conveyer belt. A plurality of electromagnetic propulsion devices are arranged on one side of the conveyer belt. Each electromagnetic propulsion device is provided with an electromagnetic propulsion block which ishorizontally arranged. Fruit separation sliding ways corresponding to the electromagnetic propulsion blocks are arranged on the other side of the conveyer belt. The dual-time judgement electromagnetic propulsion type fruit grading device carries out secondary grading according to the weight and sizes of fruits, achieves automatic recovery without damage, and is simple in structure and relativelyreasonable in cost.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a double discrimination electromagnetic propulsion type fruit grading device. Background technique [0002] The total area and total output of orchards in my country have always ranked first in the world. At the same time, the quality and industrialization level of fruits are also developing and improving, but the damage of fruits is serious, and the export volume and output of fruits in my country are extremely uneven. The main reason for this is that the post-harvest processing technology in my country has developed relatively late, and the key technology of fruit post-harvest processing - fruit grading has not been well resolved. In addition, the low level of packaging hinders the development of the domestic fruit industry. [0003] Countries and regions with developed fruit industries such as the United States and Europe have already achiev...

AI Technical Summary

Problems solved by technology

[0003] Countries and regions with developed fruit industries such as the United States and Europe have already achieved more than 95% of the total output of fruits that have been processed through simple commercialization. Their development experience shows that the main economic value of the fruit industry comes from the fruits after picking and grading. The commercialization rate of fruits after picking in our country only accounts for about 10% of the total fruit output. Most of the fruits go directly to the market without any post-harvest treatment. burden
