Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a wheat sample freeze-drying grinding device. Background Art

[0002] Freeze-dried wheat samples are generally used in research and testing to explore wheat disease-resistant genes. The testing process requires the wheat samples to be freeze-dried and ground into powder for easy research.

[0003] The prior art CN218393837U proposes a wheat grading grinding device, comprising an outer box, wherein a grading crushing mechanism, three grinding mechanisms and a filtering mechanism are arranged in the outer box, and the filtering mechanism comprises an impurity filtering plate, an inclined plate, a rectangular frame, a round rod, two racks, a fixed plate, a third driving motor and a residual wheel, wherein the impurity filtering plate is fixedly installed in the outer box, the inclined plate is fixedly installed on an inner wall of one side of the outer box, the rectangular frame is arranged below the inclined plate, the round rod is fixedly installed on the top of the rectangular frame, the round rod passes through the inclined plate and is slidably connected to the inclined plate, the two racks are respectively fixedly installed on the inner walls of both sides of the rectangular frame, the fixed plate is fixedly installed on an inner wall of one side of the outer box, the third driving motor is fixedly installed on an outer wall of one side of the fixed plate, the residual wheel is fixedly installed on the output shaft of the third driving motor, and the residual wheel is meshed with the corresponding rack, thereby realizing that the wheat can be filtered simply and effectively and impurities in the wheat can be removed.

[0004] However, there are some problems in the use of the above patent. When wheat falls from the impurity filtering plate to the inclined plate and then falls from the inclined plate to the multi-stage screen plate, the inclined plate relies on the third drive motor and the residual wheel to make the wheat fall onto the multi-stage screen plate, which is inefficient and easy to get stuck on the inclined plate. The multi-stage screen plate only relies on the slope to make the wheat enter the crushing box step by step. The wheat grading and grinding is slow and the effect is not good. The multi-stage screen plate is easy to get blocked. Moreover, when the multi-stage screen plate is blocked, it is not easy to disassemble and clean it, which reduces work efficiency and makes it inconvenient to use. Utility Model Content

A first vibration hole 28 is provided on one side of the grinding box 5. A first connecting plate 19 is fixedly connected to the inner wall of the grinding box 5 below the first vibration hole 28. A support plate 14 is fixedly connected to the lower part of the first connecting plate 19. The first vibration plate 16 is located above the support plate 14 and the first connecting plate 19. One side of the first vibration plate 16 passes through the first vibration hole 28. Two second springs 20 are fixedly connected between the first vibration plate 16 and the support plate 14, and two first springs 18 are fixedly connected between the first vibration plate 16 and the first connecting plate 19. The first vibration plate 16 passes through the first vibration hole 28 and is fixedly connected to the lower end surface thereof on one side with a first vibration motor 17. When the freeze-dried wheat sample is poured into the grinding box 5 from the pouring port 8, the two sets of first rollers 13 perform the first grinding of the freeze-dried wheat sample. The ground freeze-dried wheat sample will fall onto the first vibration plate 16. The first vibration motor 17 on the first vibration plate 16 drives the first vibration plate 16 to vibrate so that the freeze-dried wheat sample falls onto the second vibration plate 9. This has high efficiency and can effectively prevent the freeze-dried wheat sample from being blocked on the first vibration plate 16.

[0030] A second grinding assembly is provided at the lower part of the grinding box 5 for grinding the wheat sample freeze-dried after the first grinding for the second time. The second grinding assembly includes a second roller 21. There are six second rollers 21. The six second rollers 21 are divided into three groups.

The second vibration plate 9 passes through the second vibration hole 29 and is fixedly connected to the lower end face of one side with a second vibration motor 10. When the freeze-dried wheat sample after the first grinding falls onto the second vibration plate 9, the second vibration plate 9 vibrates through the second vibration motor 10, so that the freeze-dried wheat samples of different coarseness and fineness pass through sieve plates of different pore sizes and fall into different grinding chambers for a second grinding. After the second grinding, they are discharged from the discharge port 2.

[0031] The second vibration plate 9 is provided with a filtering component for grading samples, and the filtering component includes a small-pore sieve plate 24, a medium-pore sieve plate 25, and a large-pore sieve plate 27.
