[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:
[0027] This utility model provides an adjustable automatic decoction machine for Chinese herbal medicine, including a mechanism body 1. The mechanism body 1 is equipped with a vertically oriented decoction stirring shaft 2, which facilitates the support of various components and the stirring of the Chinese herbal medicine decoction inside the decoction machine. The outer circumference of the decoction stirring shaft 2 is threaded to facilitate the installation of the blade adjustment cylinder 5 via the thread. The outer circumference of the decoction stirring shaft 2 has three upward-through dovetail grooves in a ring array to facilitate the insertion and installation of the dovetail blocks of the adjustable blades 3. The bottom end face of the decoction stirring shaft 2 is provided with a regular hexagonal prism to facilitate the synchronous rotation of the auxiliary centering frame 8. The bottom end face of the hexagonal prism has a threaded blind hole for easy installation of the fixing limit post 7 via thread. The top end face of the decoction stirring shaft 2 has a fixing post for easy rotation of the decoction stirring shaft 2 on the decoction machine via bearings. The top end face of the fixing post of the decoction stirring shaft 2 has a regular hexagonal groove for easy connection with the power unit of the decoction machine for rotation. An adjustable blade 3 is inserted into the dovetail groove of the decoction stirring shaft 2 for easy adjustment of the height and movement of the adjustable blade 3. The inner end of the adjustable blade 3 is provided with a dovetail block in the vertical direction for easy assembly of the decoction stirring shaft 2 and the adjustable blade 3. The upper outer end face has a threaded blind hole for easy assembly of the anti-detachment column 4 via threaded installation. The adjustable blade 3 has the anti-detachment column 4 installed inside the threaded blind hole to prevent it from detaching from the blade adjusting cylinder 5. The outer circumference of the anti-detachment column 4 has threads for easy assembly. The outer end face of the anti-detachment column 4 has a regular hexagonal groove for easy disassembly and reassembly using tools. The outer circumference of the decoction stirring shaft 2 is threaded with the blade adjusting cylinder 5 for easy lifting and lowering via threaded engagement. The inner circumference of the blade adjusting cylinder 5 has threads for easy adjustment. The blade adjusting cylinder 5 has an annular groove on its inner circumference at the bottom, which is installed by threads. This facilitates the assembly of the anti-detachment column 4, which is located inside the annular groove to prevent the adjustable blade 3 from detaching. It also facilitates the assembly of the anti-detachment column 4, which moves around the annular groove. The outer circumference of the blade adjusting cylinder 5 has a regular hexagonal structure, which facilitates the adjustment of the blade adjusting cylinder 5 by rotating it with a tool. The top of the left side wall of the blade adjusting cylinder 5 has a threaded hole that runs through the left and right sides, which facilitates the installation of the limit anti-rotation column 6 by threads. The left side wall of the annular groove of the blade adjusting cylinder 5 has a through hole that runs through the left and right sides, which facilitates the assembly of the anti-detachment column 4, which passes through the through hole and is installed inside the threaded blind hole of the adjustable blade 3.
[0028] The blade adjusting cylinder 5 has a limit anti-rotation post 6 installed inside its threaded hole. This allows the limit anti-rotation post 6 to be inserted into the dovetail groove of the decoction stirring shaft 2 to prevent the blade adjusting cylinder 5 from rotating. The limit anti-rotation post 6 has threads on its outer circumference for easy assembly and disassembly. A limit ring plate is provided on the outer circumference of the left end of the limit anti-rotation post 6 to lock it onto the blade adjusting cylinder 5. A regular hexagonal groove is provided on the left end face of the limit anti-rotation post 6 to facilitate assembly and disassembly by rotating it with a tool. A fixing limit post 7 is installed inside the threaded blind hole of the decoction stirring shaft 2 to prevent the auxiliary centering frame 8 from detaching. The fixing limit post 7 has threads on its outer circumference for easy assembly and disassembly by rotating it with a thread. An anti-detachment ring plate is provided on the outer circumference of the lower end of the fixing limit post 7 to limit and prevent the auxiliary centering frame 8 from detaching. A regular hexagonal prism is provided on the bottom end face of the fixing limit post 7 to facilitate rotation of the fixing limit post 7 with a tool. The decoction stirring shaft 2 is equipped with an auxiliary centering frame 8, which facilitates centering of the lower end of the decoction stirring shaft 2. The auxiliary centering frame 8 has a sleeve with a through-hole regular hexagonal hole at its center, which facilitates the insertion and synchronous rotation of the regular hexagonal prism of the decoction stirring shaft 2. The sleeve of the auxiliary centering frame 8 has three auxiliary rods arranged in an inward and outward directions in a circular array on its outer circumference, which facilitates the contact wheel 9 of the inner wall with the inner wall of the decoction machine. The outer end of the auxiliary rod of the auxiliary centering frame 8 has a semi-circular head with a through-hole at its upper and lower ends, which facilitates the installation of the inner wall contact wheel 9 through the fixed shaft. The outer end face of the auxiliary rod of the auxiliary centering frame 8 has a limit groove in the middle, which facilitates the placement and limiting of the inner wall contact wheel 9. The inner wall contact wheel 9 is installed in the limit groove of the auxiliary centering frame 8 through the fixed shaft, which facilitates the contact wheel 9 with the inner wall of the decoction machine and its rotation. The inner wall contact wheel 9 has a through-hole rotating hole at its center, which facilitates the installation and rotation of the inner wall contact wheel 9 through the fixed shaft.
[0029] The specific usage and function of this embodiment are as follows:
[0030] In this utility model, such as Figure 1 As shown, the outer part between the inner wall contact wheels 9 is the cut-off part of the inner wall of the decoction machine. The inner wall contact wheels 9 are in contact with the inner wall of the decoction machine. When the decoction stirring shaft 2 rotates, the auxiliary centering frame 8 on the regular hexagonal prism of the decoction stirring shaft 2 rotates synchronously. The rotation of the auxiliary centering frame 8 drives the inner wall contact wheels 9 to rotate on the inner wall of the decoction machine, thereby preventing eccentric wobbling at the lower end of the decoction stirring shaft 2. This solves the problem that the suspended end of the stirring shaft is prone to eccentric wobbling due to centrifugal force during the rotation of the stirring shaft. Figure 1 As shown, when the main body 1 is in use, the fixing column of the decoction stirring shaft 2 is mounted on the decoction machine via bearings, so that the power unit shaft of the decoction machine is inserted into the regular hexagonal groove of the decoction stirring shaft 2. Thus, the power unit shaft drives the main body 1 to rotate and stir. Figure 1As shown, when adjusting the position of the adjustable blade 3, the limiting anti-rotation post 6 is engaged with the blade adjusting cylinder 5 by rotating the tool. This causes the limiting anti-rotation post 6 to move to the left through the thread engagement, and the right end of the limiting anti-rotation post 6 moves to the left and disengages from the dovetail groove of the decoction stirring shaft 2, as shown in the figure. Figure 6 As shown, this releases the anti-rotation pin 6 from the anti-rotation of the blade adjusting cylinder 5. The blade adjusting cylinder 5 is then rotated using a tool to engage with the threaded connection of the decoction stirring shaft 2. Note that the anti-detachment pin 4 is positioned inside the annular groove of the blade adjusting cylinder 5, as shown in the diagram. Figure 5 As shown, the assembly of the anti-detachment column 4 will not obstruct the rotation of the blade adjusting cylinder 5, allowing the blade adjusting cylinder 5 to move upward or downward through threaded engagement. The annular groove of the blade adjusting cylinder 5 hooks the assembly of the anti-detachment column 4, causing it to move upward or downward synchronously. The assembly of the anti-detachment column 4 drives the adjustable blade 3 to move upward or downward synchronously along the dovetail groove of the decoction stirring shaft 2, thereby realizing the position adjustment of the adjustable blade 3. This solves the problem that the position of the stirring blade is fixed and cannot be adjusted according to the actual situation. After the adjustable blade 3 is adjusted, the limiting anti-rotation column 6 is rotated by a tool to engage with the blade adjusting cylinder 5 through threaded engagement, causing the limiting anti-rotation column 6 to move to the right through threaded engagement. The right end of the limiting anti-rotation column 6 moves to the right and inserts into the dovetail groove of the decoction stirring shaft 2, thereby achieving the anti-rotation of the blade adjusting cylinder 5 by the limiting anti-rotation column 6.
[0031] Example 2: The difference from Example 1 is that the regular hexagonal groove of the limiting anti-rotation post 6 can also be set as a regular heptagonal groove, so that the limiting anti-rotation post 6 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the limiting anti-rotation post 6.
[0032] Example 3: The difference from Example 1 is that the regular hexagonal prism of the fixed limiting post 7 can also be set as a regular heptagonal prism, so that the fixed limiting post 7 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the fixed limiting post 7.
