Technical Field

[0001] The invention relates to the technical field of burdock processing, in particular to a burdock crushing device. Background Art

[0002] Burdock is a perennial herb of the Asteraceae family. Its roots, stems and leaves can all be used as medicine. Burdock roots can be used as fresh vegetables. Burdock roots are rich in nutrients and contain VA, VB, arctiin, inulin and other ingredients. Burdock roots are processed into burdock powder. The low moisture content of burdock powder can extend the shelf life and reduce the cost of warehousing, transportation and packaging. Burdock powder has low requirements on the size and shape of burdock roots and has a high utilization rate of burdock roots.

[0003] The burdock root needs to be crushed before it can be processed into burdock powder. The existing technology mostly uses a vertical rotating shaft to drive a blade to crush the burdock root. However, the burdock root becomes a viscous fluid after being crushed. The burdock root pieces that are not completely crushed are easy to float on the viscous fluid. The burdock root pieces that are not completely crushed need to be screened out, which affects the overall crushing effect and reduces the crushing efficiency.

[0023] 1. In the burdock crushing device of the example of the present invention, the driving device drives the blade to rotate around the horizontal axis and makes the bottom shell rotate around its vertical axis through the rotating shaft.

[0027] 5. In the burdock crushing device of the present invention, the driving device drives the blade to rotate along a horizontal axis through the rotating shaft: on the one hand, the bottom shell rotates around its axis so that the blade applies the same impact force and shear force to the burdock root, thereby ensuring the crushing effect of the burdock root; on the other hand, the rotating blade flips the viscous crushed burdock root so that the original bubbles in the viscous crushed burdock root burst and new bubbles are formed, thereby increasing the evaporation area of ​​the moisture in the viscous crushed burdock root and accelerating the drying time of the viscous crushed burdock root; on the other hand, the rotating blade hits the burdock root powder to increase the splashing amount of the burdock root powder and improve the screening efficiency of the burdock root powder.

[0044] The driving device 2 drives the blade 8 to rotate through the rotating shaft 9, and the driving device 2 drives the bottom shell 3 to rotate through the rotating shaft 9, the gear 7 and the fixed ring 16. The burdock roots in the annular cavity of the bottom shell 3 are cut by the blade 8 when rotating around the vertical axis of the bottom shell 3. The burdock roots in the annular cavity of the bottom shell 3 are all exerted with the same impact force and shear force, so as to better crush the burdock roots into smaller particles, thereby ensuring the crushing effect of the burdock roots.

[0045] Preferably, the upper cover 1 is made of transparent glass or transparent plastic, so that the crushing of the burdock root in the annular cavity of the bottom shell 3 can be observed without opening the upper cover 1, thereby reducing oxidation of the burdock root.

[0048] like Figure 1-2 As shown in Figures 4 and 5, this embodiment discloses a burdock crushing device, the structure of which is substantially the same as that of the first embodiment, except that a first opening and a second opening connecting the inside and the outside of the upper cover 1 are provided on the upper cover 1 of this embodiment, the second opening is connected to the air outlet of the air pump 14, the air inlet of the air pump 14 is connected to the air outlet of the air dehumidifier 10, and the air inlet of the air dehumidifier 10 is connected to the first opening via a conduit.

[0049] A heating device 15 is installed on the base 4 , and the heating device 15 is close to the bottom side of the bottom shell 3 .

[0050] The air pump 14 is powered by an external power source.

[0051] Preferably, the heating device 15 is a gas furnace, an electric furnace, an electric heating plate or an oil furnace.

[0052] Preferably, the air dehumidification device 10 is an electric air dehumidifier, or the air dehumidification device 10 is a silica gel dehumidification bag, an aluminum gel silica gel dehumidification bag, a zeolite silica gel dehumidification bag, a calcium chloride silica gel dehumidification bag, a lithium chloride silica gel dehumidification bag or a lithium bromide silica gel dehumidification bag.

[0053] The air pump 14 used in the present invention is a common electronic device in the prior art, and its working method and circuit structure are well-known technologies and will not be described in detail here.

[0054] The working process and principle of this embodiment are:

[0055] The burdock root crushed heating device 15 heats the viscous crushed burdock root in the bottom shell 3 through the bottom shell 3, and the driving device 2 drives the blade 8 to rotate through the rotating shaft 9.

[0056] The air pump 14 draws the gas in the bottom shell 3 and removes the moisture through the air dehumidifier 10, and then the gas flows back to the bottom shell 3. The rotating blade 8 pumps the gas in the bottom shell 3 into the viscous crushed burdock root, so that a plurality of bubbles are formed in the viscous crushed burdock root. The low humidity of the bubbles causes the moisture in the viscous crushed burdock root to enter the bubbles, thereby increasing the evaporation area of ​​the moisture in the viscous crushed burdock root. As the bottom shell 3 rotates, the rotating blade 8 periodically turns the viscous crushed burdock root, causing the original bubbles in the viscous crushed burdock root to burst and new bubbles to form, thereby accelerating the drying time of the viscous crushed burdock root.

[0057] Embodiment three:

[0058] like Figure 1-5 As shown, this embodiment discloses a burdock crushing device, and its structure is substantially the same as that of the first embodiment, except that a first opening and a second opening for connecting the inside and the outside of the upper cover 1 of this embodiment are provided, wherein the second opening is connected to an external compressed gas source, and the external compressed gas source is a carbon dioxide compressed gas source or a nitrogen compressed gas source.

[0059] A heating device 15 is installed on the base 4 , and the heating device 15 is close to the bottom side of the bottom shell 3 .

[0060] Preferably, the heating device 15 is a gas furnace, an electric furnace, an electric heating plate or an oil furnace.

[0061] The working process and principle of this embodiment are:

[0062] The burdock root crushed heating device 15 heats the viscous crushed burdock root in the bottom shell 3 through the bottom shell 3, and the driving device 2 drives the blade 8 to rotate through the rotating shaft 9.

[0063] An external compressed air source injects compressed dry gas into the bottom shell 3, and the rotating blade 8 pumps the gas in the bottom shell 3 into the viscous crushed burdock root, so that a plurality of bubbles are formed in the viscous crushed burdock root. The gas in the bubbles is dry, so that the moisture in the viscous crushed burdock root enters the gas in the bubbles. As the bottom shell 3 rotates, the rotating blade 8 periodically turns the viscous crushed burdock root, so that the original bubbles in the viscous crushed burdock root burst and new bubbles are formed, thereby accelerating the drying time of the viscous crushed burdock root.

[0064] Embodiment 4:

[0065] like Figure 2 , 4 As shown, this embodiment discloses a burdock crushing device. Based on any one of the embodiments one to three, an arc-shaped cover shell 5 is installed in the upper cover 1 of this embodiment. The cover shell 5 is located above the rotating shaft 9, and the edge of the blade 8 is in sliding contact with the inner wall of the cover shell 5.

[0066] The working process and principle of this embodiment are:

[0067] During the pulverizing process of the burdock root, the cover 5 prevents the blade 8 from throwing the burdock root fragments to the inside of the upper cover 1, and the burdock root fragments thrown to the inside of the cover 5 by the blade 8 are scraped off during the rotation of the blade 8, thereby reducing the residual burdock root fragments.

[0068] Embodiment five:

[0069] like Figure 1-2 As shown in , 4, 6-7, this embodiment discloses a burdock crushing device, and its structure is substantially the same as that of the fourth embodiment, except that, in this embodiment, the end of the cover shell 5 and the rotating shaft 9 are connected by a bearing or a rotating pin sleeve, and a mounting hole connecting the inside and the outside of the cover 1 is opened, and a rubber ring 12 is installed in the mounting hole, and an operating rod 11 is sealed and penetrated through the rubber ring 12, and one end of the operating rod 11 is rotatably connected to the outer side of the cover shell 5 by a hinge seat or a soft belt, and the rubber ring 12 is clamped on the operating rod 11, so that the friction between the rubber ring 12 and the operating rod 11 positions the operating rod 11.

[0070] The operating rod 11 moves into the upper cover 1 so that the operating rod 11 drives the cover shell 5 to rotate. When the blade 8 rotates to the cover shell 5, the blade 8 rotates downward. The distance between the cover shell 5 and the annular cavity is 0.5-3.0 cm, and the bottom end of the cover shell 5 is inserted into the viscous crushed burdock root in the bottom shell 3, so that the viscous crushed burdock root is gathered on the inner side of the cover shell 5 during the drying stage, increasing the residence time of the viscous crushed burdock root at the blade 8, increasing the amount of bubbles in the viscous crushed burdock root, and accelerating the drying of the viscous crushed burdock root.

[0071] When the sticky crushed burdock root begins to clump into powder, the cover 5 increases the number of times the blade 8 pulverizes the agglomerated burdock root powder, thereby improving the pulverization effect of the agglomerated powder.

[0072] Embodiment six:

[0073] like Figure 1-2 As shown in , 4, 6-7, this embodiment discloses a burdock crushing device, and its structure is substantially the same as that of the fifth embodiment, except that the first opening of this embodiment is connected to the air inlet of the powder filter bag 13.

[0075] The working process and principle of this embodiment are:

[0076] After the burdock root powder in the cover shell 5 is dried, the burdock root powder gathers on the inner side of the cover shell 5, and the driving device 2 drives the blade 8 to rotate through the rotating shaft 9, and the blade 8 causes the burdock root powder to splash, and the splashed burdock root powder flows into the powder filter bag 13 with the airflow, and the airflow flows out of the powder filter bag 13 through the powder filter bag 13, and the particulate matter in the burdock root powder and / or the undried burdock root powder remain in the bottom shell 3, thereby realizing the screening of the burdock root powder.

[0077] Furthermore, burdock root powder with different particle sizes can be screened by adjusting the air intake speed at the second opening.

[0078] Embodiment seven:

[0079] like Figure 6-7 As shown, this embodiment discloses a burdock crushing device, whose structure is substantially the same as that of the sixth embodiment, except that the second opening of this embodiment is located above the rotating shaft 9, and the cover 5 does not block the space between the second opening and the rotating shaft 9.

[0080] The driving device 2 is a servo motor, a speed regulating motor or a pneumatic motor commonly used in the prior art.

[0081] The airflow sprayed from the second opening into the bottom shell 3 directly acts on the burdock root powder, thereby increasing the splashing and floating of the burdock root powder and improving the sorting and screening of the burdock root powder.

[0082] Furthermore, during the drying process of the viscous and crushed burdock roots, the cover 5 blocks the space between the second opening and the rotating shaft 9 .
