Description

Technical Field

[0001] This utility model relates to the technical field of dust collection and pulverizing devices, and more specifically to a dust collection and pulverizing device for processing medicinal materials. Background Technology

[0002] Medicinal materials refer to medicinal substances used for the prevention, treatment, diagnosis of diseases, or regulation of human physiological functions. These include plant-based medicines, animal-based medicines, mineral-based medicines, and some chemical and biological products. In traditional Chinese medicine, medicinal materials are typically of natural origin and are processed before clinical application. Pulverizing medicinal materials is a crucial step in the processing, extraction, and preparation of traditional Chinese medicine. Mechanical force is used to break the materials into powders of different particle sizes to improve their utilization rate and facilitate subsequent processing.

[0003] For example, a medicinal material pulverizing device with prior art publication number CN220919532U uses a sieving component to remove powder from the pulverized medicinal material. This mechanized sieving is more convenient and faster than traditional manual sieving.

[0004] However, the existing technology described above still has the following problems in use: the position of the grinding disc in traditional pulverizing devices is usually fixed, so the particle size cannot be adjusted according to needs when pulverizing medicinal materials, which limits its use. Based on this, the present invention provides a dust-collecting pulverizing device for processing medicinal materials with high pulverizing efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a dust-collecting pulverizing device for processing medicinal materials. The device completes the pulverization of medicinal materials through the cooperation of an upper and lower grinding disc. At the same time, the spiral blades on the transmission rod can effectively avoid clogging problems, thereby significantly improving the pulverization efficiency. Furthermore, the device automatically adjusts the distance between the lower and upper grinding discs with the help of a lifting component, which facilitates the control of the size of the medicinal material particles and further improves its practicality. In addition, it is equipped with a dust-collecting device to suck up the gas in the pulverizing tank to prevent the loss of medicinal material dust and waste, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust-collecting and pulverizing device for processing medicinal materials, comprising a pulverizing tank, a cover plate fixedly provided on the top of the pulverizing tank, an upper grinding disc fixedly provided on the bottom of the cover plate, a lower grinding disc provided on the bottom of the upper grinding disc, a feeding hopper connected to the top of the upper grinding disc, a transmission rod fixedly provided on the top of the lower grinding disc, the top end of the transmission rod penetrating through the feeding hopper and extending above the feeding hopper, a spiral blade sleeved on the outer wall of the transmission rod, the spiral blade being disposed inside the feeding hopper, the top of the transmission rod being connected to the cover plate via a lifting assembly, and multiple dust-collecting pipes arranged in a circular array penetrating the top of the cover plate, each of the multiple dust-collecting pipes being connected to a dust-collecting device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a dust-collecting and pulverizing device for processing medicinal materials, including a pulverizing tank 1. A cover plate 2 is fixedly provided on the top of the pulverizing tank 1, and an upper grinding disc 3 is fixedly provided on the bottom of the cover plate 2. A lower grinding disc 4 is provided on the bottom of the upper grinding disc 3. A feed hopper 5 is connected to the top of the upper grinding disc 3. A transmission rod 6 is fixedly provided on the top of the lower grinding disc 4. The top end of the transmission rod 6 passes through the feed hopper 5 and extends above the feed hopper 5. A spiral blade 7 is sleeved on the outer wall of the transmission rod 6. The spiral blade 7 is located inside the feed hopper 5.

[0025] The top of the transmission rod 6 is connected to the cover plate 2 via a lifting assembly 8. Specifically, the lifting assembly 8 includes a bracket 81 fixed to the top of the cover plate 2. The inner walls of both sides of the bracket 81 are provided with sliding grooves 82. Nut blocks 83 are provided inside the two sliding grooves 82. A connecting plate 84 is fixed between the two nut blocks 83. The connecting plate 84 is located between the feed hopper 5 and the bracket 81. The connecting plate 84 is fixedly sleeved on the transmission rod 6. A lead screw 85 is rotatably provided inside the two sliding grooves 82. The nut blocks 83 are sleeved on the outside of the lead screw 85 and threadedly connected to the lead screw 85. The two lead screws 85 are connected by a pulley group 86. A first motor 87 is fixedly installed on one side of the top of the bracket 81. The bottom end of the output shaft of the first motor 87 is fixed to the top end of one of the lead screws 85.

[0026] The second motor 11 passes through the connecting plate 84. The bottom end of the output shaft of the second motor 11 is fixed to the top end of the transmission rod 6. The second motor 11 is located below the bracket 81.

[0027] The top of the cover plate 2 has multiple suction pipes 9 arranged in a ring array. Each suction pipe 9 is connected to a suction device 10. Specifically, the suction device 10 includes an industrial vacuum cleaner 101, which is fixed to the rear end of the pulverizing tank 1. The industrial vacuum cleaner 101 is connected to the multiple suction pipes 9 through a suction pipe 102.

[0028] In practical use, the medicinal materials are first poured into the feed hopper 5. Then, the second motor 11 drives the transmission rod 6 to rotate, which in turn drives the lower grinding disc 4 to rotate at high speed. The medicinal materials are pulverized when they flow from the feed hopper 5 to the space between the upper grinding disc 3 and the lower grinding disc 4. The pulverized medicinal powder falls into the pulverizing tank 1 through the lower grinding disc 4. At the same time, an industrial vacuum cleaner 101 is used to extract the air from the pulverizing tank 1 to prevent the loss of medicinal powder and waste. The spiral blades 7 on the transmission rod 6 agitate the medicinal materials, preventing blockages and eliminating the need for manual unblocking, thus effectively improving pulverizing efficiency. In addition, the operator can use the first motor 87 to drive the two lead screws 85, which are driven by the pulley group 86, to rotate synchronously. This drives the slider and the connecting plate 84 to descend synchronously. The connecting plate 84 moves the lower grinding disc 4 at the bottom of the transmission rod 6 downwards, realizing automatic adjustment of the distance between the lower grinding disc 4 and the upper grinding disc 3. This facilitates the adjustment of the medicinal particle size and improves practicality.

[0029] like Figure 2 As shown, a support plate 12 is rotatably connected to the bottom of the lower grinding disc 4, and the support plate 12 is in contact with the inner wall of the grinding tank 1; the support plate 12 provides support at the bottom of the lower grinding disc 4, thereby improving the rotational stability of the lower grinding disc 4.

[0030] Two symmetrically distributed dust covers 13 are installed on the top of the feed hopper 5. Both dust covers 13 are fitted over the outside of the transmission rod 6. During crushing, the workers cover the top of the feed hopper 5 with the dust covers 13 to prevent dust from being exposed.

[0031] A discharge valve 14 is connected to the center of the bottom of the crushing tank 1, and multiple support legs 15 arranged in a ring array are fixedly provided at the bottom of the crushing tank 1 to improve the stability of the device.
