Embodiment 1

[0036] see Figure 1-8, a high-strength grinder for quantitative analysis of Chinese medicinal materials, comprising a crushing cylinder 1, a rotating sleeve 2, a pressure plate 3, a differential sleeve 9, a return spring 4, a screening tube 5, a collection box 6 set on the screening tube 5, The double-row gear 7 and the negative pressure filter group, the upper cover 11 is arranged on the top of the crushing cylinder 1, the upper cover 11 is provided with an air inlet 111, the rotating sleeve 2 is set on the top of the upper cover 11, and the pressure plate 3 is located The inner and rotating sleeve 2 are connected through the sleeve, and the bottom of the pressure plate 3 is elastically slid in the axial direction with the rotating sleeve 2 through the return spring 4. The top is fixedly connected with a columnar centrifugal drive assembly 32 evenly distributed in the circumferential direction, so that when the rotating sleeve 2 rotates at a high speed, the entire pressure p...

Embodiment 2

[0038] see Figure 6 and Figure 7 The difference from Embodiment 1 is that the differential sleeve 9 is composed of a lower tube 91 located inside the rotary sleeve 2 and an upper tube 92 located outside the rotary sleeve 2, the inner periphery of the lower tube 91 is fixedly connected with a blade 911, and the inner periphery of the upper tube 92 The surface wall is fixedly connected with a spiral deflector 921. Since the deflector column 121 is set in Embodiment 1, the suction of the negative pressure fan will be reduced. The Chinese medicine granules play the role of physical and wind lifting, and the spiral deflector 921 is provided to facilitate the "climbing" of the Chinese medicine granules.

Embodiment 3

[0040] see Figure 7 , and the difference from Example 1 is that the channel 61 and the screening tube 5 are sealed and detachable connections. After the collection box 6 is collected, remove the hose connected to the quick connector 52, and then pull out the collection box 6. The collection box The outer wall of 6 is fixedly connected with a discharge pipe 62 and a filter pipe 63. The function of the filter pipe 63 is to discharge the traditional Chinese medicine with the required particle size. Both the pipe 62 and the filter pipe 63 are screwed together with a cap 64, which is convenient for closing when collecting.

[0041] Working principle: When in use, connect the drive motor 8 and the negative pressure fan to the external control electrical box, and set a feeding door (not shown in the figure) on one side of the crushing cylinder 1, and put hard Chinese medicinal materials into the crushing cylinder 1 Inside, start the driving motor 8, the driving motor 8 drives the d...

Abstract

The invention discloses a high-strength pulverizer for quantitative analysis of Chinese medicinal materials. The high-strength pulverizer comprises a pulverizing cylinder, a rotating sleeve, a pressure plate, a differential sleeve, a return spring, a screening tube, a collection box arranged on the screening tube in a sleeving manner, a double-row gear and a negative pressure filtration group; anupper cover is arranged on the top of the pulverizing cylinder; an air inlet is formed in the upper cover; the rotating sleeve is arranged at the top of the upper cover in a penetrating and sleeving manner; the pressure plate is located in the pulverizing cylinder and is connected with the rotating sleeve in a penetrating and sleeving manner; and the bottom of the pressure plate is elastically matched with the rotating sleeve in a sliding manner through the reset spring in the axial direction. According to the high-strength pulverizer, the pressure plate elastically matched in a sliding mannerin the axial direction is arranged in the pulverizing cylinder, a crushing knife is arranged at the bottom of the pressure plate, centrifugal drive combinations uniformly distributed in the circumferential distribution are arranged on the pressure plate, when the pressure plate rotates at a high speed, balance weight balls in the centrifugal drive combinations move obliquely downward, and then adownward thrust is applied to the pressure plate by a thrust spring, thereby pushing the pressure plate to move downwards to realize breakage in volume decreasing, and the crushing strength is high.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine processing, in particular to a high-strength pulverizer for quantitative analysis of Chinese medicinal materials. Background technique [0002] Quantitative analysis of traditional Chinese medicine is currently commonly used in the determination of the content of traditional Chinese medicine components. For some Chinese medicinal materials, they need to be crushed into granules or powders when they are ingested. For some hard Chinese medicinal materials, it is difficult to process them with conventional crushers, which is not convenient for mass production. . [0003] At present, in order to solve the above problems, it is necessary to carry out quantitative analysis of the medicinal properties of Chinese herbal medicines with different sizes of broken particles, and it is a difficult problem to extract different sizes of the same Chinese herbal medicine. And then affect the ...
