Abstract

Disclosed in the present invention is a plant extraction device for cyclic continuous extraction. The plant extraction device comprises a housing, wherein support legs are provided on the bottom of the housing. The present invention can continuously and repeatedly separate and squeeze crushed plants for extraction reactions, such that the plants are squeezed more sufficiently, thus achieving a better extraction effect; and can also make it convenient to recover post-extraction solution and crushed plants for reuse, thus realizing cyclic extraction. In addition, while extraction is being performed, a filter screen on which the crushed plants are placed can be caused to shake, so as to disengage the crushed plants that are tightly pressed and attached to the surface of the filter screen after being squeezed, such that the plants may not come into a pressed state. Therefore, the squeezed plants can spread out once having entered an extraction solution, so as to come into full contact with the extraction solution for reaction, thereby preventing the extraction effect from being affected due to the situation in which the plants, after being squeezed, are pressed and attached to the filter screen and thus cannot come into full contact with the extraction solution when entering the extraction solution.

Working principle: During use, pour the extraction liquid into the liquid inlet hopper 9. The extraction liquid enters the inner cylinder 3 through the liquid inlet pipe 11, fills the inner lower area of the inner cylinder 3, and starts the second motor 26 to output. The rotation of the shaft drives the round rod 27 and the crushing knife to rotate, and the plants can be put into the feed hopper 24. The plants fall down and come into contact with the crushing knife to be broken, and then enter the filter screen 4 below through the feed frame 25. , start the first motor 28 to rotate its output shaft to drive the shaft and the inner cylinder 3 to rotate intermittently. The rotation of the inner cylinder 3 drives the crushed plants located above the filter 4 to move accordingly, so that the inner wall of the outer cylinder 2 can be matched. The broken plants can be partitioned so that the broken plants are separated on each filter screen 4. As the inner cylinder 3 rotates, the inner wall of the matching opening squeezes the squeeze plate 8 to drive the pressure rod 7 and the pressure plate to rise. , compress the first spring to deform and generate force. When the remaining openings rotate to align with the position of the squeeze plate 8, the output shaft of the first motor 28 stops rotating. At this time, the first spring releases the force to drive the pressure plate, pressure rod 7 and The squeezing plate 8 descends, so that the crushed plants on the filter 4 are squeezed, so that the juice in the plants can be fully squeezed out. The juice falls along the filter 4 into the extraction liquid below for extraction reaction, and then the third The output shaft of the first motor 28 rotates again to drive the shaft and the inner cylinder 3 to rotate. In the same way, the squeeze plate 8 is squeezed to separate it from the aligned filter 4, and then corresponds to the opening of the next installation filter 4. The first motor 28 The output shaft stops rotating again, and the squeeze plate 8 squeezes the broken plants again. Through the continuous intermittent rotation of the inner cylinder 3, the broken plants can be separated, and then with the extrusion of the squeeze plate 8, It realizes the separated extrusion of the crushed plants, making the extrusion more complete, which in turn causes more juice to flow out and the extraction reaction to be more complete. The extruded crushed plants enter the bottom with the rotating inner cylinder 3. The extraction reaction is carried out in the extraction liquid, and then it is squeezed multiple times, and then enters the extraction liquid for extraction reaction, so that the plant can be continuously separated and squeezed and extracted multiple times, so that the extraction effect is better. After the extraction is completed, it needs When taking out the extracted solution, start the first electric push rod 17 to extend and drive the first connecting plate 18 and the bottom plate 19 to drop accordingly, thereby driving the plunger 23 to drop, causing the plunger 23 to leave the round hole to open it. The extracted solution flows through the round hole to the bottom plate 19 below. The bottom plate 19 is set as a plate-like member with a groove. The discharge pipe is connected to the inside of the groove. Opening the solenoid valve 31 opens the discharge pipe so that the solution can be discharged through The tube is discharged, and the solution can be collected. The second electric push rod 20 can be opened to extend and drive the second connecting plate 21 and the top plate 22 to drop. At the same time, the first electric push rod 17 continues to drop, causing the bottom plate 19 to drop, and finally the top plate 22 Leave the outlet and open it, so that the broken plants moving with the movement of the inner cylinder 3 can move to the opening and fall outward, so that they can be collected. After the collection is completed, the second electric push rod 20 and the first electric push rod can be started in reverse. The push rod 17 resets it to realize the reset of the bottom plate 19 and the top plate 22. After the collection is completed, the crushed plants and extracted solution can be poured into the filter 4 and the inner cylinder 3 through the above operation again. Through the above operation, cyclic extraction is performed, so that the plants are more fully extracted. When the inner cylinder 3 rotates, the U-shaped frame 12 drives the T-shaped rod 13 to rotate accordingly. The T-shaped rod 13 drives the driving plate 15 to move accordingly, so that the driving plate 15 The arc surface of the 16 collides with the driving rod 16, thereby squeezing the driving plate 15 to drive the T-shaped rod 13 to move in a direction away from the filter 4, and then driving the sleeve plate 14 to move accordingly, compressing the second spring to cause its deformation. force, when the driving plate 15 and the driving rod 16 are separated, the second spring releases the force to drive the sleeve plate 14 and the T-shaped rod 13 to reset, causing the T-shaped rod 13 to hit the filter 4 and cause it to vibrate, thereby extruding the filter screen. The crushed plants tightly compacted and attached to the surface of the filter 4 are shaken open, so that the plants are not in a compacted state, and then the squeezed plants can spread out when they enter the extraction liquid, so that they can fully The contact reaction with the extraction liquid avoids the situation that the plants are compacted and attached to the filter 4 after extrusion, resulting in insufficient contact with the extraction liquid when entering the extraction liquid, thus affecting the extraction effect.
