Description

Technical Field

[0001] The present invention relates to the field of detection technology, in particular to a fully automatic grain particle material crushing and detection integrated machine. Background Art

[0002] In the grain storage industry, the content of mycotoxins and heavy metals in grain is tested. The detection of mycotoxins and heavy metals in grain is carried out according to standards. The detection process covers multiple links such as crushing, mixing, quantitative weighing, liquid addition, vibration extraction, separation, pipetting, dilution, incubation and detection. The crushing link plays an indispensable and key role in the detection of the content of mycotoxins and heavy metals in grain, which can improve the release efficiency of the detection substance. The crushing process can crush the intact grain particles, so that the contact surface of mycotoxins and heavy metals is larger during extraction. After crushing and mixing, the composition of the grain sample can be made more uniform. In the existing technology, heavy metal and mycotoxin detection mainly relies on manual operation of each single machine for detection. The sample preparation and processing steps are complicated, the labor intensity is high, there are human factors, the degree of automation is low, the inspection efficiency is low, it cannot guarantee that all tests should be carried out, and the chemical reagents have an impact on human health. Develop a fully automatic crushing and testing machine for grain purchasing, which can automate and unmanned the entire process of sample processing from crushing, quantitative weighing, liquid addition, vibration extraction, separation, pipetting, dilution, incubation to physical and chemical index testing, eliminate the influence of human factors, improve inspection efficiency, and achieve the goal of fair, just and open inspection results.

[0003] The technical difficulty in the existing technology is that the automation of raw grain crushing is difficult and time-consuming. Therefore, solving the crushing problem is the key to realizing heavy metal and mycotoxin detection. When crushing, the grain needs to be placed inside the crushing box, but the crushing blades inside the crushing box are generally arranged at the bottom of the crushing box. Some grains located at a higher position of the crushing box are not easy to be crushed, or the grains located at a higher position need to sink to the bottom of the crushing box before they can be crushed by the crushing blades. It is troublesome to completely crush the grains at various positions in the crushing box, and some grains are more adhered to the inner wall of the crushing box. When there is a gap between the crushing blade and the inner wall of the crushing box, the end of the crushing blade cannot touch the grain on the inner wall of the crushing box, so that the grain on the inner wall of the crushing box cannot be completely crushed. Summary of the Invention

A rotating shaft 10 is provided at the output end of the driving motor 2, and a crushing box 3 is installed at the end of the driving motor 2. The rotating shaft 10 runs through the interior of the crushing box 3, and the middle of the rotating shaft 10 is located inside the crushing box 3. Equipped with a crushing blade 6, the crushing box 3 is fixedly installed at the end of the shell of the driving motor 2, and the output shaft of the driving motor 2 drives the rotating shaft 10 to rotate, so that the rotating shaft 10 drives the crushing blade 6 to rotate inside the crushing box 3, so that the material to be crushed can be crushed. The top of the crushing box 3 is provided with an upper cover 5, and the contact point between the crushing box 3 and the upper cover 5 is provided with a fixing hoop.

A filter screen 9 is placed on the top of the crushing box 3, and the filter screen 9 is located between the upper cover 5 and the crushing box 3. When the material needs to be discharged, the filter screen 9 can be placed on the top of the crushing box 3, and the crushing box 3 and the filter screen 9 are fixed by the fixing hoop. The qualified materials that have been crushed can be screened out from the inside of the filter screen 9. The cylindrical surface of the rotating shaft 10 is provided with a blade lifting structure 7 for adjusting the height of the crushing blade 6. The blade lifting structure 7 includes a first matching groove 73 arranged vertically. The first matching groove 73 is opened in the interior of the rotating shaft 10.

When the rotating shaft 10 drives the crushing blade 6 to rotate, the intermediate rod 76 located in the middle of the rotating shaft 10 can rotate relative to the rotating shaft 10, the middle of the intermediate gasket 71 is threadedly connected to the intermediate rod 76, and the interior of the intermediate gasket 71 is slidably connected to the interior of the rotating shaft 10,The intermediate gasket 71 and the crushing blade 6 rise and fall synchronously, and the material inside the shredding box 3 is crushed by the rising and falling crushing blade 6. Since the intermediate rod 76 rotates relative to the rotating shaft 10 and the intermediate gasket 71, the thread of the intermediate rod 76 and the intermediate gasket 71 drive the intermediate gasket 71 to rise and fall along the inside of the first matching groove 73, so that the crushing blade 6 rotates along with the rotating shaft 10 and the crushing blade 6 also rises and falls, thereby crushing different layers of material and crushing the material more thoroughly.
