[0014] A method for using a pear paste extraction device comprises the following steps:

[0015] Step 1: remove the core and peel of fresh pear fruit, place the pear pulp inside the crushing box, start the toothed disc, so that the second pulley rotates, and the first pulley rotates under the action of the belt, so as to drive one of the crushing rollers to rotate, and under the transmission action of the second gear and the first gear, the two crushing rollers rotate in opposite directions to crush the pear pulp;

[0016] Step 2: The crushed pulp enters the interior of the extraction box. At this time, the pump body is started to transport the ethanol in the storage tank into the interior of the extraction box through the first connecting pipe and the second connecting pipe, and reacts with the pear pulp to ensure that the pear pulp is completely covered with the ethanol solvent, thereby realizing the leaching process, and effectively extracting the active ingredients in the pear pulp for preparing the subsequent pear paste extract;

[0017] Step 3, when the output shaft of the servo motor rotates, it will also drive the mounting frame to rotate. Since the linkage gear and the toothed disc are meshed with each other, the mounting frame will also drive the linkage gear to rotate when it rotates, thereby further driving the rotating disc to rotate, so that the mixing rod rotates eccentrically along the rotating disc to fully mix the ethanol solvent with the pear pulp. The solvent and the pear pulp can be fully mixed and stirred. At the same time, when the first gear rotates, it will drive one end of the connecting rod to rotate eccentrically. At this time, under the action of the traction force of the connecting rod, the movable rod is driven to move up and down reciprocatingly, and the piston is driven to move synchronously. When the piston moves upward, the outside air passes through the inside of the mounting groove. When the piston moves downward, the gas inside the fixed cylinder enters the inside of the heating box through the first connecting pipe, and is heated by the heating wire to become hot air, and finally discharged into the inside of the extraction box through the second connecting pipe;

[0018] Step 4: After the extraction is completed, open the control valve outside the discharge pipe, filter through the filter screen to remove solid particles and impurities in the pear pulp, and the filtered extract enters the collection container through the discharge pipe to obtain a relatively clear pear pulp extract.

[0019] The present invention provides a pear paste extraction device having the following beneficial effects:

[0020] 1. The present invention can effectively remove the residue attached to the filter screen through the mutual coordination of the first linkage wheel, the second linkage wheel, the transmission shaft, the knocking plate, the knocking ball, the swing plate, the rigid traction rope and other structures, thereby improving the filtration efficiency of the pear paste extract, maintaining the cleanliness of the extract, and greatly improving the purity and quality of the pear paste extract.

[0021] 2. The present invention can fully mix the pear pulp and the solvent by adding a servo motor, a gear plate, a linkage gear, a mounting frame, a rotating disk, a mixing rod and other structures to increase their contact area, increase the dissolution rate of the pear paste pulp, and thus improve the extraction efficiency of the pear paste.

[0022] 3. The present invention uses the structures such as connecting rods, movable rods, fixed cylinders, first connecting tubes, heating boxes, and mounting grooves to cooperate with each other, so that hot air can be continuously added to the interior of the extraction box, which can promote the penetration of solvents into the pear pulp, thereby increasing the release and dissolution of active ingredients. This helps to improve the extraction efficiency and fully extract the active ingredients in the pear paste. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specifically, when the output shaft of the servo motor 601 rotates, it drives the mounting frame 604 to rotate, and under the action of the toothed disk 602, it drives the linkage gear 603 to rotate, thereby further driving the rotating disk 605 to rotate, so that the mixing rod 606 rotates eccentrically along the rotating disk 605, fully mixing the ethanol solvent with the pear pulp, increasing the contact area, improving the dissolution efficiency of the pear paste pulp, and improving the extraction efficiency of the pear paste. The servo motor 601 is an existing mature technology product and is well known to those skilled in the art, so it will not be repeated here.

[0035] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 3 The crushing assembly includes two crushing rollers 501, and the two crushing rollers 501 are rotatably connected to the inside of the crushing box 1. One side of one of the crushing rollers 501 is fixedly connected to a first pulley 504, and the outside of the first pulley 504 is connected to a second pulley 505 through a belt. The second pulley 505 is fixedly connected to the output end of the servo motor 601, the left end of the front crushing roller 501 is fixedly connected to the second gear 503, and the left end of the rear crushing roller 501 is fixedly connected to the first gear 502.

[0036] Specifically, the servo motor 601 is started, so that the second pulley 505 rotates, and the first pulley 504 is driven to rotate under the action of the belt, thereby driving one of the crushing rollers 501 to rotate, and under the transmission action of the second gear 503 and the first gear 502, the two crushing rollers 501 rotate in opposite directions to crush the pear pulp, thereby facilitating the subsequent extraction of pear paste.

[0037] Please see attached Figure 3 , Attachment Figure 4 and attached Figure 5 The anti-blocking component includes a first linkage wheel 701, which is fixedly connected to one end of one of the crushing rollers 501. The outside of the crushing roller 501 is connected to the second linkage wheel 702 through a belt. The outside of the second linkage wheel 702 is fixedly connected to a transmission shaft 703, one end of the transmission shaft 703 is fixedly connected to a driving wheel 709, and a rigid traction rope 708 is fixedly connected to the eccentric part of the outside of the driving wheel 709. Two limit frames 707 are fixedly connected to the outer surface of the extraction box 2, and the two limit frames 707 are connected to a swing plate 706 through a pin shaft. A torsion spring is installed on the outside of the pin shaft, and a knocking ball 705 is fixedly connected to the bottom end of the swing plate 706. The inside of the filter box 3 is detachably connected to a filter screen 710, and one end of the filter screen 710 is fixedly connected to a knocking plate 704.

[0038] Specifically, when the crushing roller 501 rotates, it will drive the first interlocking wheel 701 to rotate synchronously, and drive the second interlocking wheel 702 to rotate through the action of the belt, thereby driving the transmission shaft 703 to rotate coaxially, and then driving the driving wheel 709 to rotate, so that the rigid traction rope 708 rotates eccentrically, and under the traction of the rigid traction rope 708, one end of the swing plate 706 is driven to swing back and forth, and the swing plate 706 is used to drive the knocking ball 705 to hit the knocking plate 704, so that the residue attached to the filter screen 710 can be effectively removed, thereby improving the filtration efficiency of the pear paste extract, and maintaining the cleanliness of the extract, greatly improving the purity and quality of the pear paste extract.

[0039] Please see attached Figure 4 , Attachment Figure 7 and attached Figure 8 The gas heating component includes a fixed cylinder 803, which is fixedly connected to one end of the extraction box 2. A mounting groove 806 is provided inside the fixed cylinder 803, and a piston 807 is slidably connected inside the mounting groove 806. A movable rod 802 is fixedly connected to one side of the piston 807. The end of the movable rod 802 away from the piston 807 passes through the top of the fixed cylinder 803 and is movably connected to the connecting rod 801. A plurality of connecting holes 809 are provided on the upper surface of the fixed cylinder 803. A first connecting pipe 804 is connected to the outside of the fixed cylinder 803. Both the first connecting pipe 804 and the piston 807 are provided with a one-way valve 808. The other end of the first connecting pipe 804 is fixedly connected to a heating box 805. A heating wire 810 is installed inside the heating box 805. A second connecting pipe 811 is fixedly connected to the side of the heating box 805 away from the first connecting pipe 804.

[0040] Specifically, when the first gear 502 rotates, it will drive one end of the connecting rod 801 to rotate eccentrically. At this time, under the action of the traction force of the connecting rod 801, the movable rod 802 is driven to move back and forth up and down, and the piston 807 is driven to move synchronously. When the piston 807 moves upward, the one-way valve 808 located at the piston 807 is opened, and the one-way valve 808 inside the first connecting pipe 804 is closed, and the outside air enters the interior of the mounting groove 806 through the connecting hole 809. When the piston 807 moves downward, the one-way valve 808 located at the piston 807 is closed, and the one-way valve 808 inside the first connecting pipe 804 is opened, and the gas inside the fixed cylinder 803 enters the interior of the heating box 805 through the first connecting pipe 804, and is heated by the heating wire 810 to become hot air, and finally discharged into the interior of the extraction box 2 through the second connecting pipe 811. Thus, hot air can be continuously added to the interior of the extraction box 2, which can promote the penetration of the solvent into the interior of the pear pulp, thereby increasing the release and dissolution of the active ingredients. This helps to improve the extraction efficiency, so that the active ingredients in the pear paste are fully extracted.

[0041] Please see attached Figure 7 One end of the connecting rod 801 is rotatably connected to the outside of the first gear 502 , and the other end of the second connecting pipe 811 is connected to the outside of the extraction box 2 .

[0042] Specifically, when the first gear 502 rotates, one end of the connecting rod 801 can be driven to rotate eccentrically, and the heated gas can be transported to the interior of the extraction box 2 through the second connecting pipe 811 .

[0043] Please see attached Figure 2 , Attachment Figure 3 and attached Figure 6 One end of the rigid traction rope 708 away from the driving wheel 709 is fixedly connected to the top of the swing plate 706, and the knocking plate 704 is made of metal.

[0044] Specifically, the movement of the rigid traction rope 708 drives the swing plate 706 to swing, and the knocking ball 705 continuously hits the knocking plate 704, so that the filter screen 710 vibrates to prevent the filter screen 710 from being blocked.

[0045] Please see attached Figure 4 The bottom of the extraction box 2 is connected to the top of the filter box 3 through a feed pipe 9. A control valve is installed outside the feed pipe 9. The bottom of the filter box 3 is connected to a discharge pipe.

[0046] Specifically, after the extraction is completed, the control valve outside the discharge pipe 9 is opened, and the solid particles and impurities in the pear pulp are removed after filtering through the filter screen 710. The filtered extract enters the collection container through the discharge pipe to obtain a relatively clear pear pulp extract.

[0047] Please see attached Figure 1 , Attachment Figure 3 and attached Figure 4 The outer side of the second gear 503 is meshed with the outer side of the first gear 502, and the outer surfaces of the two crushing rollers 501 are clearance-matched.

[0048] Specifically, when the second gear 503 rotates, it drives the first gear 502 to rotate, so that the two crushing rollers 501 rotate in opposite directions, so as to exert squeezing force on the pear flesh, crush the pear flesh, and facilitate the subsequent extraction of pear paste.

[0049] Please see attached Figure 1, also includes two storage tanks 401, a pump body 403 is installed on the outside of one of the storage tanks 401, the output end of the pump body 403 is fixedly connected to the second connecting pipe 404, the input end of the pump body 403 is fixedly connected to the first connecting pipe 402, one end of the first connecting pipe 402 is connected to the top of the storage tank 401, and one end of the second connecting pipe 404 is connected to the outside of the extraction box 2.

[0050] Specifically, by starting the pump body 403, the ethanol in the storage tank 401 enters the extraction box 2 through the first connecting pipe 402 and the second connecting pipe 404, reacts with the pear pulp, and ensures that the pear pulp is completely covered by the ethanol solvent to achieve the extraction process.

[0051] A method for using a pear paste extraction device comprises the following steps:

[0052] Step 1: remove the core and peel of fresh pear fruit, place the pear pulp inside the crushing box 1, and then start the servo motor 601 to rotate the second pulley 505, and drive the first pulley 504 to rotate under the action of the belt, so as to drive one of the crushing rollers 501 to rotate, and under the transmission action of the second gear 503 and the first gear 502, the two crushing rollers 501 rotate in opposite directions to crush the pear pulp;

[0053] Step 2: The crushed pulp enters the extraction box 2. At this time, the pump body 403 is started to transport the ethanol in the storage tank 401 into the extraction box 2 through the first connecting pipe 402 and the second connecting pipe 404, and reacts with the pear pulp to ensure that the pear pulp is completely covered with the ethanol solvent, thereby realizing the leaching process, and effectively extracting the active ingredients in the pear pulp for preparing the subsequent pear paste extract;

[0054] Step 3: When the output shaft of the servo motor 601 rotates, it also drives the mounting frame 604 to rotate. Since the linkage gear 603 and the toothed disc 602 are meshed with each other, the mounting frame 604 also drives the linkage gear 603 to rotate when it rotates, thereby further driving the rotating disc 605 to rotate, so that the mixing rod 606 rotates eccentrically along the rotating disc 605 to fully mix the ethanol solvent with the pear pulp. The solvent and the pear pulp can be fully mixed and stirred. At the same time, when the first gear 502 rotates, it drives the connecting rod 8 One end of the connecting rod 801 rotates eccentrically. At this time, under the traction force of the connecting rod 801, the movable rod 802 is driven to move up and down, and the piston 807 is driven to move synchronously. When the piston 807 moves upward, the outside air passes through the inside of the installation groove 806. When the piston 807 moves downward, the gas inside the fixed cylinder 803 enters the inside of the heating box 805 through the first connecting pipe 804, and is heated by the heating wire 810 to become hot air, and finally discharged into the inside of the extraction box 2 through the second connecting pipe 811;

[0055] Step 4: After the extraction is completed, the control valve outside the discharge pipe 9 is opened, and the solid particles and impurities in the pear pulp are removed after filtering through the filter screen 710. The filtered extract enters the collection container through the discharge pipe to obtain a relatively clear pear pulp extract.

[0056] 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.

7. A method for using a pear paste extraction device, according to the pear paste extraction device according to any one of claims 1 to 6, characterized in that: The following steps are involved: Step 1: remove the core and peel of a fresh pear fruit, place the pear pulp inside a crushing box (1), and then start the servo motor (601) to rotate the second pulley (505), and drive the first pulley (504) to rotate under the action of the belt, thereby driving one of the crushing rollers (501) to rotate, and under the transmission action of the second gear (503) and the first gear (502), the two crushing rollers (501) rotate in opposite directions to crush the pear pulp; Step 2: The crushed pear pulp enters the interior of the extraction box (2). At this time, the pump body (403) is started to transport the ethanol in the storage tank (401) into the interior of the extraction box (2) through the first connecting pipe (402) and the second connecting pipe (404), and reacts with the pear pulp to ensure that the pear pulp is completely covered with the ethanol solvent, thereby achieving an extraction process, and effectively extracting the active ingredients in the pear pulp for preparing the subsequent pear paste extract; Step 3: When the output shaft of the servo motor (601) rotates, it also drives the mounting frame (604) to rotate. Since the linkage gear (603) and the toothed disc (602) are meshed with each other, when the mounting frame (604) rotates, it also drives the linkage gear (603) to rotate, thereby further driving the rotating disc (605) to rotate, so that the mixing rod (606) rotates eccentrically along the rotating disc (605), and the ethanol solvent and the pear pulp are fully mixed. The solvent and the pear pulp can be fully mixed and stirred. At the same time, when the first gear (502) rotates, it drives the connecting rod (801 ) rotates eccentrically, and at this time, under the action of the traction force of the connecting rod (801), the movable rod (802) is driven to move back and forth up and down, and the piston (807) is driven to move synchronously. When the piston (807) moves upward, the outside air passes through the interior of the mounting groove (806). When the piston (807) moves downward, the gas inside the fixed cylinder (803) enters the interior of the heating box (805) through the first connecting pipe (804), and is heated by the heating wire (810) to become hot air, and finally discharged into the interior of the extraction box (2) through the second connecting pipe (811); Step 4: After the extraction is completed, the control valve outside the discharge pipe (9) is opened, and the solid particles and impurities in the pear pulp are removed after filtering through the filter screen (710). The filtered extract enters the collection container through the discharge pipe to obtain a relatively clear pear pulp extract.
