DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a cold extraction machine for Chinese herbal medicine ingredients includes an extraction tank 1, characterized in that: a cleaning component 5 is installed inside the extraction tank 1, and the cleaning component 5 is located at the top of the extraction tank 1. The cleaning component 5 includes a water inlet ring 501 rotatably connected to the center of the inner wall of the top of the extraction tank 1, the top of the water inlet ring 501 is in an open state, and both sides of the outer wall of the bottom of the water inlet ring 501 are rotatably connected to a water outlet head 503, and multiple nozzles of the water outlet head 503 are distributed in a V shape. The circumferential outer wall of the water inlet ring 501 is fixedly sleeved with a gear ring 502, and the inner wall of the top of the extraction tank 1 is rotatably connected to a transmission gear 504, and the transmission gear 504 is meshed with the gear ring 502. A motor 505 is fixedly installed on the outer wall of the top of the extraction tank 1, and the rotating shaft of the motor 505 and the transmission gear 504 are coaxially fixed.

[0025] A gear ring three 508 is fixedly sleeved on the top of the circumferential outer wall of the multiple water outlet heads 503, a fixing frame 506 is coaxially fixed to the inner wall of the top of the extraction tank 1, and the same gear ring two 507 is fixedly connected to both ends of the fixing frame 506, and the multiple gear rings three 508 are meshed with the gear ring two 507.

[0026] Clean water is sprayed outward from multiple water outlet heads 503, and motor 1 505 is started at the same time. Motor 1 505 drives transmission gear 504 to rotate, and transmission gear 504 drives water inlet ring 501 to rotate through gear ring 1 502 meshing with it. Therefore, multiple water outlet heads 503 will revolve while discharging water, thereby ensuring that other positions of the tank wall can also be cleaned. Gear ring 2 507 is restricted by the fixed frame 506, so gear ring 3 508 outside the water outlet head 503 will be meshed with gear ring 2 507, so that the water outlet head 503 will rotate while revolving, thereby further increasing the cleaning effect.

[0027] like Figure 2 and Figure 4As shown, a support frame 4 is fixedly installed at the bottom of the outer wall of both sides of the extraction tank 1, and a moving component 6 is installed inside the two support frames 4.

[0028] The moving component 6 includes the same bidirectional screw rod 601 rotatably connected to the inner walls at both ends of the support frame 4, and a mounting block 603 is threadedly connected to the threads at both ends of the bidirectional screw rod 601. The two mounting blocks 603 are slidably inserted with the same limit rod 602. The two ends of the limit rod 602 are respectively fixedly connected to the inner walls at both ends of the support frame 4. The bottom of the two mounting blocks 603 is rotatably connected to a push rod 604, and the two push rods 604 are symmetrically arranged. One end of the bottom of the two push rods 604 is rotatably connected to the same moving plate 605, and a plurality of universal wheels are installed on the outer wall at the bottom of the moving plate 605.

[0029] The outer walls of one side of the two support frames 4 are rotatably connected to a bevel gear 606, and the two bevel gears 606 are coaxially fixed to one end of two bidirectional screw rods 601 respectively. The two support frames 4 are rotatably connected to the same transmission rod 608, and the transmission rod 608 is fixedly sleeved with two bevel gears 2, and the two bevel gears 1 606 are respectively meshed with the two bevel gears 2. A motor 2 607 is fixedly installed on the outer wall of one side of the support frames 4, and the rotating shaft of the motor 2 607 is coaxially fixed to one end of the transmission rod 608.

[0030] The second motor 607 drives the transmission rod 608 to rotate, and the two bevel gears 2 outside the transmission rod 608 will drive the two bevel gears 1 606 to rotate synchronously, and then the two bidirectional screw rods 601 will also be driven to rotate at the same time, and the two mounting blocks 603 restricted by the limit rod 602 will be driven away from each other by the bidirectional screw rod 601, and the two mounting blocks 603 can extend the movable plate 605 downward through the two push rods 604, and then the rollers at the bottom of the mounting blocks 603 can lift the device. At this time, the friction force encountered by the device during the movement process will be greatly reduced, ensuring that the movement is more convenient.

[0031] like Figure 1 and Figure 2 As shown, a negative pressure pump 2 is fixedly installed on the top of the outer wall of one side of the extraction tank 1, and the negative pressure pump 2 is connected to the inside of the extraction tank 1. The processed medicinal materials and the extract are put into the extraction tank 1, and then the feeding port of the extraction tank 1 is closed, and then the negative pressure pump 2 is started to pump the air inside the extraction tank 1 outward, so that the boiling point of the extractant is reduced. Therefore, the extractant will boil at a lower temperature, and the active ingredients in the medicine will be continuously extracted.

[0032] like Figure 1 and Figure 2 As shown, a water inlet 3 is fixedly connected to one side of the top outer wall of the extraction tank 1, the water inlet 3 is connected to the inside of the water inlet ring 501, and a solenoid valve is arranged inside the water inlet 3 to guide the external clean water into the water inlet 3, and the clean water enters the water inlet ring 501 through the water inlet 3.

[0033] The utility model provides a cold extraction machine for Chinese medicine ingredients, and the specific working principle is as follows:

[0034] When the device is working, the processed medicinal materials and the extract are put into the extraction tank 1, and then the feeding port of the extraction tank 1 is closed, and then the negative pressure pump 2 is started to pump out the air inside the extraction tank 1, so that the boiling point of the extractant is reduced. Therefore, the extractant will boil at a lower temperature and continuously extract the effective ingredients in the medicine. After the extraction is completed, the liquid medicine and the medicinal materials are discharged from the extraction tank 1, and then the external clean water is introduced into the water inlet 3. The clean water enters the water inlet ring 501 through the water inlet 3 and is then sprayed outward from multiple water outlet heads 503. At the same time, the motor 1 505 is started, and the motor 1 505 drives the transmission gear 504 to rotate. The transmission gear 504 drives the water inlet ring 501 to rotate through the gear ring 1 502 meshing with it. Therefore, the multiple water outlet heads 503 will revolve while discharging water, thereby ensuring that other positions of the tank wall can also be cleaned, and the gear ring 2 507 is fixed by the fixing frame. 506 is restricted, so the tooth ring three 508 outside the water outlet head 503 will be meshed with the tooth ring two 507, so that the water outlet head 503 will rotate while revolving, thereby further increasing the cleaning effect. If the extraction tank 1 needs to be transferred, it only needs to start the motor two 607, and the motor two 607 drives the transmission rod 608 to rotate. The two bevel gears two outside the transmission rod 608 will drive the two bevel gears one 606 to rotate synchronously, and then the two bidirectional screw rods 601 will also be driven to rotate at the same time, and the two mounting blocks 603 restricted by the limit rod 602 will be driven away from each other by the bidirectional screw rod 601. The two mounting blocks 603 can extend the moving plate 605 downward through the two push rods 604, and then the rollers at the bottom of the mounting blocks 603 can lift the device. At this time, the friction force encountered during the movement of the device will be greatly reduced, ensuring that the movement is more convenient.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
