Description

Technical Field

[0001] The present invention relates to the technical field of mugwort processing, and in particular to a mugwort drying machine and a drying method. Background Art

[0002] Artemisia argyi (H. Lév. & Vaniot) is a perennial herb or slightly subshrubby plant in the genus Artemisia in the Asteraceae family. It has a prominent, slightly long and thick taproot, numerous lateral roots, and a recumbent underground rhizome. The stem is solitary or few in number, and the plant has a strong aroma. The leaves are short, grayish-white pubescent with white glandular dots and small pits. The inflorescence head is oval and sessile or nearly sessile. The achenes are long ovate or oblong.

[0003] Moxibustion has a long history, as documented in Cao Xi's "Cao's Moxibustion Prescriptions," written during the Three Kingdoms period. Moxibustion has demonstrated remarkable therapeutic benefits for tumors on or within the human body. The entire mugwort plant is used as a medicinal herb, boasting benefits such as warming the meridians, removing dampness, dispelling cold, stopping bleeding, reducing inflammation, relieving asthma, relieving coughs, stabilizing pregnancy, and combating allergies. It is mentioned in historical herbal texts such as the Compendium of Materia Medica and the Shennong Herbal Classic, where it is described as a "key hemostatic medicine." Mugwort is also a commonly used gynecological medicine, particularly effective for treating gynecological conditions characterized by cold-deficiency syndromes. It also treats chronic bronchitis and asthma in the elderly. Boiling it in water for bathing can prevent postpartum maternal and fetal infections. It can also be used to make medicinal pillows and vests for treating chronic bronchitis and asthma in the elderly, as well as stomachaches caused by cold-deficiency syndromes.

[0004] Fresh mugwort needs to be dried in time after harvesting in order to be stored for a long time. Chinese patent document CN214842097U discloses a special dryer for mugwort. This dryer type is to place the mugwort to be dried in a mugwort storage box, use an electric heating tube to heat the air in the drying chamber of the box, and then under the action of a powerful fan, let the hot air take away the moisture in the mugwort, thereby achieving the effect of drying the mugwort. The hot air containing moisture discharged from the drying chamber is dried by an air drying mechanism, and after drying, it is discharged back into the drying chamber, so that a circulating air flow is formed in the box, which not only saves energy but also speeds up the drying efficiency of the mugwort. However, if this dryer has the problem of uneven drying, it needs to be sorted and dried in batches for secondary drying, and the mugwort leaves need to be separated from the mugwort stems before drying. There are many processes and the efficiency of mugwort preparation is low. Summary of the Invention

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figures 1 to 7 As shown, the mugwort drying machine according to an embodiment of the present invention includes: a shell 1, a clamping assembly 4, a heating plate 6 and a first driving member 7.

[0038] like Figures 1 to 3 As shown, the housing 1 is cylindrical, with a first opening 13 provided on its sidewall and a funnel-shaped discharge port provided at the bottom. A spiral groove 2 is provided at the top of the housing 1. The spiral groove 2 has a starting end and a terminal end. The starting end of the spiral groove 2 is located at the center of the top surface of the housing 1, and the terminal end is close to the first opening 13. A partition plate 3 is provided within the spiral groove 2, dividing the spiral groove 2 into a first groove 21 and a second groove 22. The first groove 21 and the second groove 22 are interconnected at the starting end and the terminal end of the spiral groove 2. A sealing cover 12 is also provided at the top of the housing 1 to seal the spiral groove 2 to prevent dust from entering.

[0039] There are multiple clamping assemblies 4 , which are evenly spaced and distributed in the first slot 21 and the second slot 22 . Two adjacent clamping assemblies 4 are hinged to each other through a hinge to form an annular structure.

[0040] like Figure 3 and Figure 5 As shown, the clamping assembly 4 includes a first shaft 41, a stopper 42, a clamping cylinder 43, and a clamping claw 44. The stopper 42 is fixedly connected to the first shaft 41 and slides into the first groove 21 and the second groove 22. The bottom end of the stopper 42 abuts against the top of the partition plate 3 and the housing 1, thereby preventing the clamping assembly 4 from sliding downward. The stopper 42 is a gear. A first rack 10 is provided on the side wall of the spiral groove 2. The stopper 42 can engage with the first rack 10. When the stopper 42 moves along the first groove 21 and the second groove 22, the stopper 42 engages with the first rack 10, allowing the clamping assembly 4 to slowly rotate. The top end of the clamping cylinder 43 is fixedly connected to the bottom end of the first shaft 41. The inner wall of the clamping cylinder 43 is provided with three clamping claws 44 evenly spaced along its circumference. Each clamping claw 44 has a triangular structure, and the clamping claw 44 is elastically connected to the clamping cylinder 43 via a spring.

[0041] The separating device 5 is a rack gear, located at the starting point of the spiral groove 2. A second gear 45 is provided on the first shaft 41, with which the separating device 5 can mesh. The pitch of the teeth of the separating device 5 is smaller than that of the first rack gear 10. When the clamping assembly 4 moves at the starting point of the spiral groove 2, the second gear 45 meshes with the separating device 5, enabling the clamping assembly 4 to rotate at high speed. The sidewall of the clamping cylinder 43 is provided with a plurality of second openings 46 spaced apart along its circumference, and the second openings 46 are located above the clamping jaws 44.

[0042] There are multiple heating plates 6 , which are evenly spaced apart along the partition plate 3 , and the top of each heating plate 6 is fixedly connected to the partition plate 3 .

[0043] The first driving member 7 is a motor, which is fixedly connected to the top of the shell 1, and its output end is fixedly connected to a push plate 8. The outer wall of the push plate 8 is provided with a plurality of push blocks 9 evenly distributed along its circumference. The push blocks 9 can stop against the first shaft 41. When the first driving member 7 drives the push plate 8 to rotate, the push blocks 9 can push the first shaft 41 to move, thereby driving the clamping assembly 4 to move along the first groove 21 and the second groove 22.

[0044] like Figure 6 and Figure 7 As shown, rotating wheels 11 are provided at both ends of the partition plate 3, rotatably connected to the partition plate 3. The sidewalls of the rotating wheels 11 are provided with a plurality of grooves evenly spaced along their circumference. When the clamping assembly 4 moves from the first groove 21 to the second groove 22, or from the second groove 22 to the first groove 21, the first shaft 41 engages with the grooves on the rotating disk, causing the hinge to abut against the rotating wheel 11. The movement of the clamping assembly 4 drives the rotating wheel 11 to rotate, thereby preventing the hinge from abutting against the partition plate 3 during movement, thereby hindering the movement of the clamping assembly 4.

[0045] The drying method of the mugwort drying machine according to the embodiment of the present invention comprises the following steps:

[0046] The first step is loading. The first driving member 7 drives the clamping assembly 4 to move along the first groove 21 and the second groove 22. When the clamping assembly 4 moves to the first opening 13, the worker can insert the mugwort to be dried into the clamping tube 43. The clamping claw 44 in the clamping tube 43 can clamp the mugwort rod, thereby fixing the mugwort rod.

[0047] The second step is drying. The clamping assembly 4 containing the mugwort moves from the terminal end of the spiral groove 2 along the first groove 21 to the starting end of the spiral groove 2. During the movement, the clamping assembly 4 will pass through multiple heating plates 6, which can dry the mugwort. In the process of movement, the clamping assembly 4 can slowly rotate under the action of the first rack 10 and the stop block 42, driving the mugwort to rotate, thereby improving the drying efficiency.

[0048] The third step is separation. When the clamping assembly 4 containing mugwort moves to the starting end of the spiral groove 2, the separating device 5 engages with the second gear 45, causing the clamping assembly 4 to rotate rapidly, thereby driving the mugwort to rotate rapidly. When the mugwort is completely dried, the mugwort leaves and the mugwort stems are separated under the action of centrifugal force. If the mugwort leaves do not separate from the mugwort stems, it means that there is still moisture in the mugwort and it is not completely dried.

[0049] The fourth step is to take the material. The separated mugwort moves along the second groove 22 from the starting end of the spiral groove 2 to the ending end of the spiral groove 2. When the mugwort moves to the first opening 13, the worker can pull out the completely separated mugwort stems and replace them with new mugwort to be dried. The mugwort that is not completely separated can continue to be dried and separated for the second time.
