Traditional grinding equipment generally includes blade type and collision type. For example, Chinese utility model patent CN2024203390520 provides a Dendrobium officinale grinding device. In the description of the grinding device in this scheme, it is recorded that "when the Dendrobium officinale is put through the crushing pipe from the feed inlet, it will be squeezed and crushed by two crushing rollers, and then fall into the grinding bin for grinding." In the above patent scheme, the method of crushing the Dendrobium officinale first and then grinding is adopted, and after screening through the mesh of the sieve plate, the Dendrobium officinale powder is obtained.

[0003] Although the above-mentioned Dendrobium officinale grinding device adopts the method of first segmenting and then grinding, which can improve the grinding efficiency, it still has the following disadvantages: 1.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present application.

[0024] It should be clear that the embodiments described below are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by technicians in the relevant field without making creative work are within the scope of protection of the present application. Example 1

[0025] like Figure 1-Figure 7 As shown, a device for gradient powder of Dendrobium officinale includes a grinding mechanism; the grinding mechanism includes a pressure block 15, a grinding block 1, a rotating rod 2, a rotating drive motor 18, a driving wheel 19 and a transmission wheel 16; the rotating drive motor 18 and the driving wheel 19 are synchronously connected in transmission, and the transmission wheel 16 and the driving wheel 19 are intermittently meshed and connected in transmission; a cam is eccentrically fixed to the side end of the rotating rod 2, the grinding block 1 is provided with a rotating through groove, the rotating rod 2 is rotatably penetrated in the rotating through groove, and the cam is fitted with the inner wall of the rotating through groove; a cavity is left between the pressure block 15 and the grinding block 1 for inserting the whole Dendrobium officinale. The driving wheel 19 includes a meshing tooth portion 21 and a sliding bar 20, and the meshing tooth portion 21 and the sliding bar 20 are both in transmission connection with the transmission wheel 16. A grinding plate 14 is provided between the pressure block 15 and the grinding block 1. The grinding plate 14 includes a cutting portion and a grinding portion. The grinding block 1 is provided with a segmented blade corresponding to the cutting portion, and a grinding protrusion matched with the grinding portion.

[0026] The connection relationship and working principle of the components of the grinding mechanism are as follows: When the Dendrobium officinale material is placed between the grinding block 1 and the pressure block 15. Since the rotating rod 2 is eccentrically connected to the cam, when the rotating rod 2 drives the cam to rotate eccentrically, it will drive the grinding block 1 connected to the cam to move slightly in the up and down directions. At the same time, since the grinding block 1 is set obliquely, the lower end of the grinding block 1 will collide with the grinding plate 14, which is also set obliquely, during the shaking process, thereby cutting or crushing the Dendrobium officinale plant.

[0027] In the above process, since the driving wheel 19 and the transmission wheel 16 are intermittently driven, specifically: When the meshing tooth portion 21 on the driving wheel 19 contacts the transmission wheel 16, the transmission wheel 16 rotates, and the driving wheel 19 is rotationally connected with the transmission wheel 16. At this time, the grinding block contacts back and forth with the grinding plate, thereby grinding the Dendrobium officinale into powder.

[0028] When the slide bar 20 on the driving wheel 19 contacts the toothed portion (between two adjacent toothed portions) on the transmission wheel 16, the transmission wheel 16 does not rotate. At this time, the driving wheel 19 and the transmission wheel 16 do not transmit.

[0029] The above two processes are periodically rotated, so that the grinding work is intermittent, which is conducive to heat dissipation and also helps the ground powder to fall into the screen.

[0030] like Figure 7 As shown, the process of the grinding plate 14 and the grinding block 1 acting on the Dendrobium officinale plant is as follows: A blade is installed on the upper side of the grinding plate 14. Similarly, a blade is also installed on the upper end side of the grinding block 1. When the grinding plate 14 and the grinding block 1 are close to each other, the blade will break the Dendrobium officinale segments. When the broken segments fall downward, the grinding protrusions on the grinding block 1 and the grinding parts on the grinding plate 14 come into contact, and the fallen broken segments will be ground into powder, and then fall into the screen 13.

[0031] like Figure 7 As shown, the grinding mechanism also includes a connecting rod 17, a telescopic rod 6, a shock-absorbing spring 7 and a fixed seat 5; one end of the connecting rod 17 is rotatably connected to the grinding block 1, and the other end is rotatably connected to the fixed seat 5; one end of the telescopic rod 6 is rotatably connected to the grinding block 1, and the other end is rotatably connected to the fixed seat 5, the connecting rod 17 is located above the telescopic rod 6, the shock-absorbing spring 7 is sleeved on the outer end of the telescopic rod 6, one end of the shock-absorbing spring 7 is fixed to the grinding block 1, and the other end is fixed to the fixed seat 5.

[0032] In actual work, the staff can change the length of the sliding rod 32 so that the distance between the grinding plate 14 and the grinding block 1 can be adjusted, thereby adapting the staff to grind powders of different particle sizes. Example 2

[0033] This embodiment also includes a screening mechanism, which includes a screen 13, a fixed plate 11 and a driving component that drives the screen 13 to vibrate periodically up and down; the screen 13 and the fixed plate 11 are elastically connected. The driving assembly includes an auxiliary transmission wheel 3, a rotating wheel 9, a transmission belt 4, a rotating rod 31, a sliding block, a sliding rod 32, a return spring 30, a rotating seat 29, a sliding seat 25, a vertical sliding rod 33, a positioning rod 27, and a sliding rod sleeve 28; the auxiliary transmission wheel 3 and the rotating wheel 9 are connected by a transmission belt 4; one end of the rotating rod 31 is synchronously connected to the rotating wheel 9 for rotation, and the other end is fixed to the sliding block; the sliding rod 32 is slidably connected to the sliding block, and accordingly, a sliding through groove adapted to the sliding rod 32 is provided on the sliding block; the upper end of the sliding rod 32 is fixed to the rotating seat 29, the rotating seat 29 is rotatably connected to the sliding seat 25, the return spring 30 is sleeved on the sliding rod 32, one end of the return spring 30 is fixed to the rotating seat 29, and the other end is fixed to the sliding block; the positioning rod 27 is slidably connected to the sliding rod sleeve 28, the sliding rod sleeve 28 is fixed to the sliding seat 25, the vertical sliding rod 33 is slidably driven on the sliding seat 25, and the end portion is fixed to the sliding rod sleeve 28.

[0034] like Figure 4 As shown, both ends of the positioning rod 27 are fixed to the fixing plate 11 through an L-shaped connecting rod 10 .

[0035] like Figure 6 As shown, a sliding protrusion 26 is provided at the lower end of the screen 13 , and correspondingly, a groove adapted for sliding of the sliding protrusion 26 is provided at the upper end of the sliding seat 25 .

[0036] like Figure 4 As shown, a hollow fixing column 12 is provided on the fixing plate 11 , an insertion column is provided at the lower end of the screen 13 , and a buffer spring is connected between the insertion column and the fixing column 12 .

[0037] like Figure 1 The figure also includes a containing basket 21 , which is fixedly arranged below the screen 13 . The screen 13 is provided with powder dropping holes, which are correspondingly located above the containing basket 21 .

[0038] The working principle of the screening mechanism is: like Figure 8 and Fig. 9 As shown in FIG. 1 , the process of the upper end of the sliding seat lifting the screen 13 upward is shown. Figure 8 As shown, when the rotating rod 31 rotates with the rotating wheel 9, the sliding block 8 is driven to rotate, which will compress the return spring 30, so that the sliding rod sleeve 28 moves to the right along the positioning rod 27, and the sliding block 8 moves upward along the sliding rod 32. Finally, the sliding seat 25 moves upward, thereby lifting the screen 13 upward. When the sliding seat 25 slides to the right until it slides out of the area of ​​the screen 13, the screen 13 returns to its original position due to no force, and the sliding seat 25 moves downward again. Figure 8-Figure 9The process is a cycle. In the above cycle, the sieve 13 moves up and down, and the Dendrobium officinale powder with the required particle size can be quickly shaken off into the receiving basket 21 and collected.
