[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 A juicing device for pears, including a fixed frame 1, characterized in that: a bottom shell 2 is fixedly connected to the upper end of the fixed frame 1, a discharge pipe 3 is fixedly connected to one end of the bottom shell 2, a feed pipe 4 is fixedly connected to the other end, a top shell 5 is provided above the bottom shell 2, the bottom shell 2 and the top shell 5 are connected on one side by a hinge 6, and the other side is detachably connected by a fixing ear 7 and a bolt 8.

[0031] The discharge pipe 3 and the inlet pipe 4 are both equipped with quick-release components 9 at the ends that connect to the bottom shell 2;

[0032] The quick-release assembly 9 includes a bearing 901, and an mounting ring 902 is fixedly installed on the inner ring of the bearing 901. One end of the mounting ring 902 is provided with a lower limit protrusion 903 along the circumferential direction.

[0033] The inner wall of the top shell 5 is provided with an upper limit protrusion 501. The upper limit protrusion 501 and the lower limit protrusion 903 are used to limit the ends of the upper half filter screen 10 and the lower half filter screen 11, respectively.

[0034] The inner wall of the upper limit protrusion 501 is provided with a limiting protrusion 5011, and the outer wall of the end of the upper half filter screen 10 is provided with a groove 1101 that is adapted to the limiting protrusion 5011.

[0035] It should be noted that: Firstly, when the top shell 5 and bottom shell 2 are connected by the fixing lugs 7 and bolts 8, the limiting protrusion 5011 on the upper limit protrusion 501 can be inserted into the groove 1001 of the upper half filter screen 10, preventing the upper half filter screen 10 and the lower half filter screen 11 from rotating with the mounting ring 902 and the inner ring of the bearing 901 during the process of the variable diameter screw 12 rotating to squeeze the pear juice. Secondly, fixing lugs 7 are fixedly connected to the outer walls of both the top shell 5 and the bottom shell 2. Tightening the bolts 8 that connect the two fixing lugs 7 completes the fixation of the top shell 5 and the bottom shell 2.

[0036] A variable diameter screw 12 is provided between the upper half filter screen 10 and the lower half filter screen 11. The larger diameter end of the variable diameter screw 12 is rotatably connected to the end of the discharge pipe 3 through a rotating shaft 16, and the smaller diameter end extends into the feed pipe 4.

[0037] The smaller diameter end of the variable diameter screw 12 is fixedly connected to a rotating shaft 13, which passes through the end of the feed pipe 4 and is fixedly connected to the output shaft of the geared motor 14.

[0038] The top of the feed pipe 4 is fixedly connected to the feed hopper 15, and the feed hopper 15 is connected to the inside of the feed pipe 4.

[0039] Among them, multiple slag discharge ports 301 are opened on the pipe wall of the discharge pipe 3.

[0040] The discharge pipe 3 is equipped with a spring 17, which is sleeved on the outside of the rotating shaft 16. One end of the spring 17 is fixedly connected to the end wall of the discharge pipe 3, and the other end is fixedly connected to the pressure plate 18 that is slidably sleeved on the rotating shaft 16.

[0041] The bottom of the bottom shell 2 is fixedly connected to a drain pipe 19, which is connected to the inside of the bottom shell 2.

[0042] Working principle: During operation, the geared motor 14 starts, driving the rotating shaft 13 to rotate, which in turn drives the variable diameter screw 12 to rotate, pouring the pears from the feed hopper 15 into the feed pipe 4. Pushed forward by the variable diameter screw 12, the pears are subjected to increasingly stronger compression during transport as the diameter of the screw gradually increases from the feed pipe 4 to the discharge pipe 3, causing the juice to be squeezed out. The squeezed juice flows out through the mesh of the upper half filter screen 10 and the lower half filter screen 11, eventually collecting at the bottom of the bottom shell 2 and being discharged and collected through the drain pipe 19.

[0043] When cleaning or replacing the filter screen is required, the bolts 8 connecting the bottom shell 2 and the fixing ears 7 on the top shell 5 can be removed, and the top shell 5 can be flipped up along the hinge 6 to open it. At this time, the inner surface of the upper limit protrusion 501 on the inner wall of the top shell 5 will release the pressure limit on the end surface of the upper half filter screen 10, and the upper half filter screen 10 can be directly removed. The end surface of the lower half filter screen 11 overlaps with the lower limit protrusion 903. Because the reducing screw 12 is blocked, it cannot be directly removed. It is necessary to rotate the lower half filter screen 11 along the axis of the reducing screw 12. During the rotation, the end of the lower half filter screen 11 will drive the mounting ring 902 to rotate synchronously with the inner ring of the bearing 901 through the lower limit protrusion 903. When the lower half filter screen 11 rotates to the upper position, it can be removed. Then, the removed upper half filter screen 10 and lower half filter screen 11 can be cleaned or replaced. Since the lower limit protrusion 903 is fixedly connected to one end of the mounting ring 902 and can rotate synchronously with the inner ring of the bearing 901 along with the mounting ring 902, when the lower half filter screen 11 rotates to the top, it can push the lower limit protrusion 903 and the mounting ring 902 on one side to rotate and reset with the inner ring of the bearing 901. The lower limit protrusion 903 will not interfere with the disassembly of the lower half filter screen 11.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
