Description

Technical Field

[0001] The present invention belongs to the field of traditional Chinese medicine decocting, and specifically relates to a drum-type decocting machine for traditional Chinese medicine. Background Art

[0002] During the process of taking traditional Chinese medicine, it is often necessary to decoct it to extract the effective components in the medicine. With the development of technology, various decocting machines have been produced for decocting traditional Chinese medicine, and the application of decocting machines in the traditional Chinese medicine industry is becoming more and more extensive. Due to the development of decocting technology and the reasons of traditional Chinese medicine materials themselves, the amount of decocted herbal pieces in a single prescription is getting larger and larger.

[0003] Existing decocting machines do not stir during the process of decocting and extracting traditional Chinese medicine. Herbal pieces need to be decocted for a long time or multiple times, otherwise it is difficult to decoct thoroughly, which reduces the efficacy of the traditional Chinese medicine liquid. When decocting large herbal pieces, a large amount of water is required, resulting in a much larger amount of decocted liquid than the amount to be taken, and the extra liquid will be wasted. Reducing the amount of added water will result in the phenomenon of being difficult to decoct thoroughly or not being able to hold the decoction. The separation of the liquid and the dregs is not thorough, and there will be some high-concentration liquid residues in the dregs, which will be lost with the dregs. Moreover, after the decocting is completed, it is only washed with water, which can only wash away the surface waste liquid. Since the drum is inside the decocting machine, the tablets are not easy to clean, and the outer pot of the decocting machine is not easy to clean either. And the medicinal stains adsorbed on the barrel wall will basically still remain inside the machine and be decocted together with the next prescription, causing potential hazards.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

The buffer pad 32 is located at the upper end of the trapezoidal support frame. There are two buffer pads 32, which are spaced apart. A support block 31 is provided at the upper end of the buffer pad 32. The axial sleeve of the pot body 29 is located on the support block 31. The formed support base 3 is used to support the decocting pot assembly 2, and the buffer pad 32 reduces the vibration generated during the working process.

[0020] In a further embodiment, the decocting pot assembly 2 includes a pot body 29. A roller 21 is rotatably provided in the pot body 29. A water inlet 9 is provided near the upper end of the pot body 29, and the water inlet 9 is connected to an external water source through a water pipe to supply water into the pot body 29.

[0021] Specifically, as Figure 2 shown, the upper end of the pot body 29 is open, and a lid locking device 12 for cooperating with and locking the pot lid 11 is provided on the outer periphery of the opening. In one embodiment, a number of lid locking devices 12 are circumferentially distributed on the outer periphery of the opening of the pot body 29, and the pot lid 11 is fixed at the opening of the pot body 29 through the lid locking device 12. In another embodiment, the pot lid 11 is hinged to one side of the opening of the pot body 29, and a number of lid locking devices 12 are provided on the opposite side of the hinge, so that the pot lid 11 can be flipped open and closed to the opening of the pot body 29. On the basis of the above embodiments, openings are provided on both sides of the pot body 29, and a rotating shaft is provided at the opening. The rotating shaft is coaxially connected to both axial ends of the roller 21 to drive the roller 21 to rotate. A number of filter holes are provided on the peripheral wall of the roller 21.

[0022] In a further embodiment, a heating plate 5 is provided at the lower end of the pot body 29 for heating the water in the pot body 29 for decocting and cleaning.

[0023] In a further embodiment, a drainage device 4 is also connected to the lower end of the pot body 29, and the drained medicine liquid after decocting is discharged through the drainage device 4, and the sewage after cleaning can also be discharged.

[0024] Specifically, a drain port is provided at the bottom end of the pot body 29. In one embodiment, the drain port is connected to a three-way valve, and the three-way valve is respectively connected to a drain pipe and a medicine discharge pipe. The drain pipe and the medicine discharge pipe are respectively communicated to the outside of the box body 1. After decocting is completed, the three-way valve connects the pot body 29 and the medicine discharge pipe, and the medicine liquid is discharged through the medicine discharge pipe. Water for cleaning is injected into the pot body 29 through the spraying device, and the three-way valve is switched to connect the pot body 29 and the drain pipe to discharge the waste water in the pot body 29. In another embodiment, a water outlet is provided on the box body 1, and the drain pipe and the drain pipe are communicated with the water outlet through a three-way valve. In still another embodiment, the drain port of the pot body 29 is connected to a water outlet pipe, and the water outlet pipe is communicated with the water outlet on the box body 1. A three-way valve is connected to the outside of the water outlet, and the three-way valve is respectively connected to a drain pipe and a medicine discharge pipe.

[0025] In a further embodiment, a cylinder cover 22 is provided on the roller 21. The roller 21 is a cylindrical structure with a circumferential opening, and the cylinder cover 22 is covered at the opening for sealing.

[0026] Specifically, as Figures 4 to 6As shown, a fixing plate 211 is correspondingly and fittingly provided at the opening of the drum 21. A limiting plate 212 protrudes from the fixing plate 211. A chute is formed by the space between the limiting plate 212 and the fixing plate 211. A part of the lid 22 of the drum can slide in the chute to seal the opening of the drum 21. The lid 22 of the drum includes a mounting plate 213, a lid handle 23, an assembly plate 231 and side plates 232. The mounting plate 213 is connected to the assembly plate 231. The mounting plate 213 is sized corresponding to the fixing plate 211. A notch 214 is provided on the mounting plate 213. The notch 214 is sized and positioned corresponding to the limiting plate 212. The mounting plate 213 can be placed in the chute through the notch 214. The assembly plate 231 is formed by connecting multiple curved surfaces. Side plates 232 are connected to both ends of the curved surfaces. A lid handle 23 is connected between the two side plates 232. The lid 22 of the drum places the mounting plate 213 at the bottom of the lid 22 in the chute corresponding to the notch 214 of the fixing plate 211, and then slides along the axial direction of the drum 21, so that the mounting plate 213 is clamped between the fixing plate 211 and the limiting plate 212, preventing the lid 22 of the drum from falling off during the rotation of the drum 21.

[0027] In a further embodiment, as shown in the figure, the drum 21 includes barrel walls 25 on both axial sides. Positioning holes 27 are provided on the barrel walls 25 corresponding to pin holes 233. The lid 22 of the drum is installed on the barrel walls 25 through a locking pin 24 and cooperates with the fixing plate 211 to prevent the lid 22 of the drum from rotating circumferentially.

[0028] In a further embodiment, a shaft hole 234 is provided at the axial center position of the barrel wall 25 of the drum 21. A rotating shaft is rotatably installed in the shaft hole 234. The support base 3 is a hollow chamber formed by brackets. A driving mechanism 7 is provided near one end along the axial direction of the drum 21. The driving mechanism 7 drives the first rotating shaft 71 to rotate, and then drives the drum 21 to rotate.

[0029] Specifically, a shaft sleeve is provided outside the shaft hole 234 of the drum 21. A square hole is provided at the axis of the shaft sleeve. One end of the first rotating shaft 71 is square corresponding to the square hole and is inserted into the square hole. The driving mechanism 7 drives the first rotating shaft 71 to rotate, and the drum 21 is driven to rotate through the square hole.

[0030] In a further embodiment, a locking mechanism 8 is provided at the other end of the drum 21 corresponding to the driving mechanism 7. One end of the locking mechanism 8 is connected to the other end of the drum 21 through a rotating shaft. The rotating shaft is inserted into the shaft hole 234 through the locking mechanism 8, and the drum 21 can be rotatably placed in the pot body 29 in cooperation with the rotating shaft at the other end.

[0031] Specifically, as Figure 8 and Figure 9As shown, the locking mechanism 8 is any existing achievable locking device or structure. In this implementation, taking the eccentric wheel locking mechanism as an example, a flat plate is provided at one end of the pot body 29 corresponding to the driving mechanism 7. The locking mechanism 8 includes a lock catch 81 and a handle 82. The lock catch 81 is rotatably installed on the flat plate, and the handle 82 is rotatably clamped in the lock catch 81. One end of the handle 82 is connected to a connecting rod, and the other end of the connecting rod is connected to an eccentric wheel. A bushing is provided at the perforation of the pot body 29, and a second rotating shaft 83 is movably arranged in the perforation and the bushing. Two baffles are spaced apart at the end of the second rotating shaft 83 away from the drum. The eccentric wheel is located between the baffles. By rotating the connecting rod to drive the eccentric wheel to rotate, the second rotating shaft 83 is driven to move axially, completing the assembly and disassembly of the drum 21. The lock catch 81 is symmetrically arranged on the flat plate along the axis of the connecting rod. By controlling the lock catch 81 to rotate and open, the handle 82 can be rotated out from the lock catch 81 and rotated to another lock catch 81. The lock catch 81 is in a locked state under normal conditions and is rotated and opened in a direction away from the handle 82 to enable the handle 82 to rotate.

[0032] In a further implementation, a slide rail groove 26 is provided on the barrel wall 25 of the drum 21. One end of the slide rail groove 26 extends to the shaft hole 234, and the other end extends to the outer periphery of the barrel wall 25. The rotating shaft slides in the slide rail groove 26 to complete the assembly and disassembly of the drum 21.

[0033] Specifically, the slide rail groove 26 is for assembly. The slide rail groove 26 protrudes from the barrel wall 25 and is arranged on the outside. One end extends to the shaft hole 234, and the other end extends to the outer periphery of the barrel wall 25. The shaft hole 234 can penetrate the barrel wall 25 or, relative to the depth of the slide rail groove 26, the depth of the shaft hole 234 is deeper, so that during the rotation of the drum 21, the rotating shaft will not fall off along the slide rail groove 26. During the installation process, the rotating shaft moves along the slide rail groove 26 from the outer periphery to the shaft hole 234, enabling the drum 21 to be rotatably located inside the pot body 29.

[0034] In a further implementation, protrusions 28 are provided inside the drum 21. The protrusions 28 extend axially and are evenly spaced circumferentially. By rotating the protrusions 28, the tablets inside the stirring drum 21 are flipped, and at the same time, the water inside the pot body 29 is stirred to fully blend the liquid medicine. In this way, it is possible to fry the tablets thoroughly. Using a large amount of water results in the output amount of the medicine being far greater than the limit requirement of the dosage for taking, and the problem that it is difficult to fry the tablets thoroughly with less added water. Moreover, setting the protrusions 28 can also avoid the problem that the tablets cannot be fully immersed in water and cannot be cooked thoroughly. By flipping the medicine with the protrusions 28 and stirring the liquid medicine at the same time, the tablets do not need to be fully immersed in water, nor do they need to add too much water, achieving a relatively balanced state between frying the tablets thoroughly and the added water amount and the dosage for taking.

[0035] In a further embodiment, a shock-absorbing wheel 6 is provided at the bottom of the support base 3, which facilitates the movement of the decocting machine and simultaneously reduces the vibration generated during the operation of the decocting machine.

[0036] Specifically, the shock-absorbing wheel 6 includes a roller 61 and a wheel post 62. The wheel post 62 is telescopically disposed on one side of the roller 61. During the movement, the wheel post 62 contracts and the roller 61 contacts the ground. After positioning and during the operation, the wheel post 62 extends and contacts the bottom surface. The wheel post 62 has a certain elasticity to reduce the vibration generated by the decocting machine during the operation.

[0037] In a further embodiment, an operation display screen 13 is further provided on the box body 1, which is used to display the working state of the decocting machine, facilitating the operator to observe and operate according to the working state of the decocting machine. An emergency stop switch is provided on one side of the display screen 13. The operator can forcibly stop the operation through the emergency stop switch according to the working conditions, improving the working safety.

[0038] In the embodiment of the present invention, the box body 1 forms an outer shell sleeved on the support base 3. A hollow chamber is formed inside the shell, and the upper side is open. The pot body 29 is placed into the box body 1 from the opening. The upper side of the pot body 29 is open, and a support plate extending outward in the circumferential direction of the opening is erected at the opening and is supported by the box body 1 for the first time. The support base 3 provides secondary support for the decocting pot assembly 2, mainly through the support base 3. A shock-absorbing wheel 6 is installed at the bottom end of the support base 3 to reduce the shock of the decocting machine in the working state. A buffer pad 32 on the support base 3 provides secondary shock absorption. The roller 21 is driven to rotate by a driving motor. The roller 21 is provided with an opening, a cylinder cover 22 is provided at the opening, a plurality of filter holes are provided on the roller 21, a cover handle 23 and an assembly plate 231 are provided on the cylinder cover 22, and a plurality of filter holes are also provided on the assembly plate 231. The medicinal liquid is discharged through the filter holes.
