A shaft is fixed at the center of the left side of the helical gear. A transmission gear is fixed on the outer surface of the shaft. A bottom ring is rotatably connected to the lower part of the inner cavity. A rotating ring and a ring rail are fixed sequentially from the outside to the inside on the upper surface of the bottom ring. A guide groove is formed on the inner side of the ring rail. Guide rods are movably connected to the front and rear of the guide groove. The two guide rods are fixedly connected to the two lifting rods respectively. The left end of the shaft extends through to the outside of the crushing cylinder and is fixed with a motor.

[0006] Furthermore, the bottom ends of the two lifting rods are rotatably connected to two connecting rods, and the square groove has plate grooves on both the left and right sides. A bottom plate is slidably connected inside the plate grooves, and side grooves are opened on the lower front and rear sides of the bottom plate.

[0017] To make the technical solution of the present invention clearer, the following description is in conjunction with the appendix. Figure 1-11 Specific embodiments will be described in further detail for the present invention.

[0018] A fruit pulp crushing device for pre-processing fruit juice includes a crushing cylinder 1, a hopper 2 fixed to the top of the crushing cylinder 1, a square groove 3 on the lower surface of the crushing cylinder 1, and a circular groove 4 on the upper surface of the crushing cylinder 1. The square groove 3 and the circular groove 4 are internally connected. Two vertical grooves 5 are formed on the inner sidewalls of the circular groove 4 and the square groove 3. The tops of the two vertical grooves 5 extend to the upper surface of the crushing cylinder 1. An annular rotating groove 6 is formed on the inner sidewall of the circular groove 4. A through groove 7 is formed on the left side inside the rotating groove 6. An annular inner cavity 8 is formed on the left side inside the through groove 7. The inner cavity 8 is internally connected to the two vertical grooves 5. The rotating groove 6 is internally connected to the two vertical grooves 5. A valve plate 10 is slidably connected to the upper part of the circular groove 4. A lifting rod 11 is slidably connected to the inside of the vertical grooves 5. A connecting block 32 is integrally formed at the top of the lifting rod 11. Both connecting blocks 32 are fixedly connected to the valve plate 10. The rotating groove 6 is internally connected to the vertical groove 5. The upper and lower sides are rotatably connected to a ring frame 17, and the two ring frames 17 are rotatably connected. A cutting wheel 18 is fixed inside the ring frame 17. The cutting wheel 18 is composed of several cutting blades. An outer groove 19 is opened on the outer surface of the ring frame 17. A helical tooth ring 20 is fixed inside the outer groove 19. A helical gear 21 is meshed between the two helical tooth rings 20. A shaft 22 is fixed at the center of the left side of the helical gear 21. A transmission gear 23 is fixed on the outer surface of the shaft 22. A bottom ring 25 is rotatably connected to the lower part of the inner cavity 8. A rotating ring 26 and a ring rail 27 are fixed from the outside to the inside on the upper surface of the bottom ring 25. A guide groove 28 is opened on the inner side of the ring rail 27. Guide rods 29 are movably connected to the front and rear sides of the guide groove 28. The two guide rods 29 are fixedly connected to the two lifting rods 11 respectively. The left end of the shaft 22 extends to the outside of the crushing cylinder 1 and is fixed with a motor 24. During operation, fruit material is fed into hopper 2, and motor 24 is controlled to operate, causing shaft 22, transmission gear 23, and helical gear 21 to rotate. Transmission gear 23 causes rotating ring 26 to rotate, which in turn drives bottom ring 25 and ring rail 27 to rotate. The rotating ring rail 27 guides guide rod 29 through guide groove 28 with height difference during rotation, driving lifting frame 11 and connecting block 32 to raise valve plate 10. The valve plate 10 opens with the circular groove 4, allowing the fruit to enter the circular groove 4. At the same time, when helical gear 21 rotates, the two helical gear rings 20 drive the two ring frames 17 to drive the corresponding internal cutting wheels 18 to rotate in opposite directions, thereby cutting the falling fruit.

[0019] Reference Figure 3-7 Two lifting rods 11 are rotatably connected to two connecting rods 13 at their bottom ends. The square groove 3 has plate grooves 9 on both the left and right sides. A bottom plate 12 is slidably connected inside the plate groove 9. Side grooves 31 are opened on the lower front and rear sides of the bottom plate 12. The top of the connecting rod 13 is located inside the side groove 31 and is rotatably connected to the bottom plate 12. When the lifting rod 11 rises, the two connecting rods 13 push the corresponding bottom plates 12 to slide open along the plate grooves 9, allowing the crushed fruit pulp to fall into the next production step.

[0020] Reference Figure 1-4The square groove 3 is equipped with four crushing rollers 14. The front and rear ends of the crushing rollers 14 extend to the outer surface of the crushing cylinder 1. The rear ends of the four crushing rollers 14 are fixed with drive wheels 15. The outer surfaces of the four drive wheels 15 are jointly provided with three drive belts 16. The four drive wheels 15 are connected by the three drive belts 16. The front surface of the crushing cylinder 1 is fixed with a second motor 34. The output shaft of the second motor 34 is fixedly connected to the front end of the crushing rollers 14. The operation of the second motor 34 causes the crushing rollers 14 connected to it to rotate. Under the transmission connection of the four drive wheels 15 and the three drive belts 16, the other three crushing rollers 14 rotate synchronously to crush the falling fruit.

[0021] Reference Figure 6-11 The upper surface of the rotating ring 26 is provided with several toothed grooves 30. The rotating ring 26 is connected to the transmission gear 23 through the toothed grooves 30. When the transmission gear 23 rotates, it can make the rotating ring 26 rotate, thereby driving the bottom ring 25 and the ring rail 27 to rotate.

[0022] Reference Figure 2 A bracket 33 is fixed on the outer surface of the crushing cylinder 1 below the motor 24. The bracket 33 is fixedly connected to the bottom of the motor 24 to support the motor 24 and make it more stable during operation.

[0023] Reference Figure 3 The top and bottom of the valve plate 10 are both conical structures. Fruits located in the hopper 2 can slide down the cone to the outer edge of the valve plate 10. When the valve plate 10 rises, it is more conducive to the fruit entering the circular groove 4.

[0024] Reference Figure 3 The two base plates 12 together form a V-shaped structure, which facilitates the juice and pulp to slide between the two base plates 12. When the two sides of the base plates 12 move, the pulp and pulp can slide out of the device better and enter the next step.

[0025] Reference Figure 3-4 The four crushing rollers 14 are located above the two base plates 12 and below the cutting rollers 18. This allows the crushing rollers 14 to perform secondary crushing after the fruit initially cut by the cutting rollers 18 falls to the ground. Furthermore, the crushing rollers 14 can more fully crush the fruit under the obstruction of the base plates 12, thereby improving the degree of crushing.

[0026] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
