[0034] A connecting plate 49 is fixedly installed on the outer wall of the extrusion seat 41, a guide groove 5 is opened on the inner wall of the crushing tank 1, a guide block 51 is slidably installed on one end of the guide groove 5, and the end of the connecting plate 49 away from the extrusion seat 41 is fixedly connected to one side of the guide block 51, and a third rotating rod 52 is rotatably installed in the middle of the crushing tank 1, and a rotating disk 53 is fixedly installed on one end of the third rotating rod 52, and a driving rod 54 is fixedly installed on one side of the rotating disk 53, and a push rod 55 is rotatably installed on one end of the driving rod 54. The end of the connecting plate 49 close to the extrusion seat 41 is fixed A hinged seat 56 is installed, and one end of the push rod 55 away from the driving rod 54 is hinged to the hinged seat 56. By setting the guide groove 5 and the guide block 51, the guide block 51 slides in the vertical direction along the inner wall of the guide groove 5, and the extrusion seat 41 is kept lifted in the vertical direction through the connecting plate 49. By driving the third rotating rod 52 to rotate, the third rotating rod 52 makes the driving rod 54 revolve around the axis of the rotating disk 53 through the rotating disk 53. The driving rod 54 can lift and reciprocate the extrusion seat 41 through the push rod 55, the hinged seat 56 and the connecting plate 49.

[0035] A transmission rod 57 is rotatably installed at the bottom end of the crushing tank 1, and a first synchronous wheel 58 is fixedly installed at one end of the third rotating rod 52 away from the rotating disk 53 and one end of the transmission rod 57.

When the first rotating rod 26 rotates, the first rotating rod 26 can rotate the third rotating rod 52 through the second synchronous wheel 62 and the second synchronous belt 63. The third rotating rod 52 can rotate the transmission rod 57 through the first synchronous wheel 58 and the first synchronous belt 59. The transmission rod 57 can rotate the third rotating shaft 6 through two third bevel gears 61. The third rotating shaft 6 can rotate the conical rotating seat 42. The conical rotating seat 42 generates centrifugal force during the rotation process. The generated centrifugal force causes the fruit puree in the guide channel 48 to overflow downward along the edge of the upper end surface of the conical rotating seat 42 and fall into the receiving tray 13.

[0036] Working principle: When the raw materials for fresh fruit puree processing need to be crushed, the operator first adds the raw materials to be crushed into the feeding hopper 11, and then turns on the servo motor 25. The driving shaft of the servo motor 25 rotates the first rotating rod 26, and the first rotating rod 26 rotates the second rotating rod 36 through the two second bevel gears 37. The second rotating rod 36 rotates the fan gear 38, and the fan gear 38 rotates the driving gear 39 by a quarter of a turn. The driving gear 39 rotates the two sealing disks 31 through the second rotating shaft 34 and the two L-shaped connecting rods 35. Ninety degrees, at this time, the two sealing plates 31 are not in contact with the bottom of the feeding hopper 11, and the bottom of the feeding hopper 11 is in an open state. The raw materials in the feeding hopper 11 fall into the processing hopper 12 through the inclined surface of the conical guide cover 21. As the sector gear 38 rotates again, one of the sealing plates 31 contacts the bottom of the feeding hopper 11, and the bottom of the feeding hopper 11 is sealed, and the raw materials in the feeding hopper 11 stop falling downward, thereby conveniently realizing the controlled amount of raw materials for fresh fruit puree processing, avoiding the influence of the raw materials crushing effect due to the addition of more raw materials at one time; At the same time, the first rotating rod 26 rotates the first rotating shaft 22 through the two first bevel gears 27, and the first rotating shaft 22 rotates the plurality of crushing blades 23 and the scraper 24. The crushing blades 23 crush the raw materials entering the processing bucket 12 to form fruit puree. The scraper 24 scrapes off the fruit puree attached to the bottom wall of the processing bucket 12, and the fruit puree falls into the feed inlet 43 of the extrusion seat 41, and falls to the axis position of the conical rotating seat 42 through the feed inlet 43. At the same time, the first rotating rod 26 rotates the third rotating rod 52 through the two second synchronous wheels 62 and the second synchronous belt 63, the third rotating rod 52 rotates the transmission rod 57 through the two first synchronous wheels 58 and the first synchronous belt 59, the transmission rod 57 rotates the third rotating shaft 6 through the two third bevel gears 61, the third rotating shaft 6 rotates the conical rotating seat 42, and the conical rotating seat 42 generates centrifugal force during the rotation process. The generated centrifugal force causes the puree to pass through a notch 46 and enter a guide channel 48. At the same time, the centrifugal force causes the puree to flow in multiple guide channels 48, so that the puree is dispersed; The third rotating rod 52 causes the driving rod 54 to revolve around the axis of the rotating disk 53 through the rotating disk 53. The driving rod 54 causes the extrusion seat 41 to reciprocate and rise and fall through the pushing rod 55, the hinged seat 56 and the connecting plate 49. During the vertical descent of the extrusion seat 41, multiple conical pressure rings 44 enter the corresponding guide channels 48 to squeeze the fruit puree in the multiple guide channels 48 to crush the fruit puree. As the conical rotating seat 42 rotates, the crushed fruit puree overflows downward along the edge of the upper end surface of the conical rotating seat 42, falls into the receiving plate 13, and is discharged through multiple discharge holes 14 and the discharge pipe 15, thereby conveniently realizing the secondary crushing processing of the fruit puree, thereby effectively improving the crushing effect of the fruit puree and improving the quality of the fresh fruit puree formed by the processing.
