Grinding equipment for pesticide residue detection for Internet-of-Things melon and fruit sales

Abstract

The invention relates to the technical field of Internet sales detection and discloses grinding equipment for pesticide residue detection for Internet-of-Things melon and fruit sales. The equipment comprises a shell, wherein a convex block is arranged at the inner side of the shell; a grinding cylinder is movably connected to the inner wall of the middle of the shell; a cleaning rod is movably connected to the outer side of the grinding cylinder; a reset spring sleeves the outer side of the cleaning rod; a grinding roller is movably connected to the inner wall of the middle of the grinding cylinder; and an electromagnet is fixedly connected to the inner wall of the middle of the grinding roller. According to the grinding equipment for pesticide residue detection for Internet-of-Things melon and fruit sales, the grinding cylinder drives the cleaning rod to move, the cleaning rod drives the reset spring to move, and then the shell and the convex block are used in cooperation, so that the cleaning effect is achieved; and the cleaning rod is in contact with the convex block through rotation of the grinding cylinder and is squeezed, at the moment, the reset spring is compressed, the cleaning rod is in contact with the outer side of the grinding roller, so that melon and fruit pulp rhizome samples attached to the surface of the grinding roller are cleaned out, and more sufficient grinding is achieved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things sales detection, in particular to a grinding device for detecting pesticide residues for melon and fruit sales in the Internet of Things. Background technique [0002] With the continuous improvement of cultivation technology, the growth period of melons and fruits has become shorter and shorter, and with the aggravation of environmental pollution, the pests and diseases of melons and fruits have become more and more serious. To reduce the damage of pests, melons and fruits can be marketed after they are ripe. In order to ensure food safety, it is necessary to detect the pesticide residues on the surface of melons and fruits in terms of concentration before they are put on the market for sale. [0003] In the prior art, it is necessary to prepare and store samples of melons and fruits, and the preparation of test samples is very important. Only after the samples are fully crushed and gr...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a grinding device for detecting pesticide residues in melons and fruits sold on the Internet of Things, which has the advantages of simple operation, sufficient prevention of adhesion and grinding, and solves the problem of root and stem melons and fruits in the process of sample preparation. , due to the high viscosity of the sample and the large number of fruit stems, it is easy to cause the sample to adhere and cannot be fully ground
