A receiving bucket 4 is slidably inserted on the bottom inner wall of the shell 1. A filter plate 41 is welded on the inner wall of the receiving bucket 4. A fixing column 42 is welded at the center of the outer wall of the filter plate 41. One end of each rope 31 away from the baffle 3 is fixed on the outer wall of the fixing column 42. Under the action of the self-gravity of the receiving bucket 4, the rope 31 is always kept in a taut state. A transmission groove 221 is provided on the top outer wall of the turntable 22. The transmission groove 221 A number of equally spaced circumferentially distributed gears 5 are rotatably plugged on the inner wall of the housing 1, a transmission shaft 51 is welded on the outer wall of each gear 5, the transmission shaft 51 corresponds to the baffle 3 one by one, a circumferentially distributed meshing teeth 13 are welded on the top inner wall of the housing 1, the gear 5 and the meshing teeth 13 are meshed with each other, a gear ring 21 is welded on the outer ring wall of the feed hopper 2, a motor 8 is welded on the top outer wall of the housing 1, a gear 2 81 is welded on the main shaft of the motor 8, the gear 2 81 and the gear ring 21 are meshed with each other, each baffle 3 is slidably sleeved on the outer wall of the corresponding transmission shaft 51, a spring 32 is welded between the outer wall of each baffle 3 and the inner wall of the transmission groove 221, a polished rod section 512 is arranged on the outer walls at both ends of each transmission shaft 51, a threaded section 511 is arranged on the outer wall of each transmission shaft 51 located between the polished rod sections 512 at both ends, and the baffle 3 is adapted to the threaded section 511 and the polished rod section 512;

[0036] A separation mechanism, used for peeling off the remaining pulp on the core, the separation mechanism is arranged on the housing 1;

[0037] A pressing mechanism, used for pressing the pulp, the pressing mechanism being arranged on the housing 1;

[0038] And a discharge mechanism is used to discharge the fruit cores, and the discharge mechanism is arranged on the shell 1.

[0039] In the initial state, the baffle 3 is located on the light rod section 512 close to the side of the gear 1 5. At this time, the spring 1 32 is in a stretched state, and the baffle 3 is stored in the storage chamber 222, so that the feed hopper 2 is in an open state. The surrounding range of the rope 31 is an inverted cone at this time, and the distance between the ropes 31 is smaller than the diameter of the fruit sample, so that the inverted cone area surrounded by the ropes 31 can receive the sample.

[0040] The above-mentioned de-nucleation mechanism is further explained as follows: when working, the sample is put into the feed hopper 2, and the sample is intercepted by the rope 31 and cannot fall into the receiving bucket 4. The motor 8 is started, and under the meshing action of the gear 2 81 and the gear ring 21, the feed hopper 2 drives the turntable 22 to rotate, and under the meshing action of the gear 1 5 and the meshing teeth 13, the gear 1 5 drives the transmission shaft 51 and the cam 52 to rotate, and the transmission shaft 51 drives the threaded segment 511 to rotate. Under the action of the spring 1 32, the baffle 3 and the threaded segment 511 always maintain an abutment state, so that when the threaded segment 511 rotates, under the action of the thread cooperation, the baffle 3 moves closer to the inside along the threaded segment 511, and when the baffle 3 moves When it moves to the light rod section 512 on the side away from the gear 1 5, the spring 1 32 is in a compressed state. At this time, the baffle 3 closes the feed hopper 2 to prevent the sample from splashing out. At the same time, the baffle 3 drives the top end of the rope 31 to move together, so that the turntable 22 drives the baffle 3 to rotate during the process of twisting the rope 31, so that the rope 31 cuts the flesh and finally wraps the core through the twisting force, and then the core is intercepted above the receiving bucket 4, and the flesh is squeezed and falls into the receiving bucket 4 through the gap between the ropes 31, so as to achieve the effect of core removal. There is no need to clamp and position the sample, and the samples can be processed in batches. The operation is simple and fast, which greatly improves the work efficiency.

[0041] Specifically, the separation mechanism includes a floating frame 6, and a plurality of floating frames 6 equidistantly distributed on the outer wall of the bottom of the turntable 22 are slidably inserted, and the floating frames 6 correspond to the baffles 3 one by one. A cam 52 is welded on the outer wall of each gear 5 away from the transmission shaft 51, and the cam 52 is adapted to the floating frame 6. A limiting rod 33 is welded on the outer wall of each baffle 3 close to the axis of the feed hopper 2, and a spring 2 61 is welded between the outer wall of each floating frame 6 and the outer wall of the turntable 22. A telescopic rod 1 62 is fixed to the outer wall of each floating frame 6 in the horizontal direction, and a scraping column 63 is welded on the outer wall of the output end of each telescopic rod 1 62. The scraping column 63 is slidably mounted on the outer wall of the limiting rod 33, and a protrusion 631 is provided on the outer wall of each scraping column 63.

[0042] The above-mentioned separation mechanism is further explained: when the baffle 3 approaches, it drives the scraping column 63 to approach the sample, so that the scraping column 63 can squeeze and crush the sample to a certain extent, thereby improving the liquid output rate of the sample, and at the same time facilitating the rope 31 to cut the pulp and wrap the core, and during the rotation of the gear 5, it drives the cam 52 to rotate, so that the cam 52 can move the floating frame 6 up and down, so that the floating frame 6 drives the scraping column 63 to move up and down, thereby achieving the effect of scraping the sample, further improving the liquid output rate, and at the same time being able to scrape off the residual pulp on the core, thereby improving the utilization rate of the sample.

[0043] Specifically, the pressing mechanism includes a roller 65, and a vertically distributed telescopic rod 64 is welded on the bottom outer wall of any floating frame 6. The output end of the telescopic rod 64 is L-shaped and rotatably sleeved on the outer wall of the fixed column 42, and a roller 65 is rotatably sleeved on the outer wall of the output end of the telescopic rod 64.

[0044] The above-mentioned pressing mechanism is further explained: the fallen pulp falls on the filter plate 41 in the receiving bucket 4, and when the turntable 22 drives the floating frame 6 to rotate, the floating frame 6 drives the roller 65 to rotate, so that the roller 65 rotates around the fixed column 42. Since the roller 65 is in contact with the filter plate 41, the pulp on the filter plate 41 can be squeezed during the rotation of the roller 65, and the squeezed tissue fluid is discharged through the bottom of the receiving bucket 4.

[0045] Specifically, the discharge mechanism includes a handle 72, which is slidably inserted on the outer wall of the receiving bucket 4, and a limiting groove 12 is provided at the bottom of the shell 1. The handle 72 is slidably inserted in the limiting groove 12. The fixed column 42 extends to the outer wall below the filter plate 1 41 and a filter plate 2 7 is rotatably sleeved thereon. A coil spring 71 is welded between the outer wall of the filter plate 2 7 and the outer wall of the fixed column 42. The large diameter end of the coil spring 71 is fixed to the end wall of the handle 72. The filter plate 1 41 fits tightly with the filter plate 2 7. The filter hole diameter of the filter plate 2 7 is smaller than the filter hole diameter of the filter plate 1 41. The filter hole diameter of the filter plate 1 41 is larger than the diameter of the fruit core. The outer wall of the filter plate 2 7 is provided with avoidance grooves 73 that are staggered with the filter holes.

[0046] In the initial state, the filter holes of the filter plate 1 41 and the filter plate 2 7 are aligned, so that the pulp is intercepted by the filter plate 2 7 in the receiving bucket 4 and will not be directly discharged through the filter holes of the filter plate 1 41 .

[0047] The above-mentioned discharge mechanism is further explained: after the processing is completed, the control motor 8 drives the gear 2 81 to reverse, so that the baffle 3 and the rope 31 are reset, so that the fruit core can fall into the receiving bucket 4 through the gap between the ropes 31. At the same time, the handle 72 is pulled outward, and the handle 72 pulls the coil spring 71 to drive the filter plate 2 7 to rotate, so that the filter plate 2 7 drives the avoidance groove 73 to rotate to align with the filter hole of the filter plate 1 41, so that the fruit core can be discharged through the filter hole of the filter plate 1 41, and the rotation process of the roller 65 can push the fruit core to move, so that the fruit core can enter the filter hole of the filter plate 1 41. At the same time, the receiving bucket 4 can be pushed up to make the rope 31 relax and bend, thereby further increasing the gap between the ropes 31 to ensure that the fruit core can fall off smoothly.

[0048] The working principle and use process of the present invention are as follows: when working, the sample is put into the feed hopper 2, and the sample is intercepted by the rope 31 and cannot fall into the receiving bucket 4. The motor 8 is started, and under the meshing action of the gear 2 81 and the gear ring 21, the feed hopper 2 drives the turntable 22 to rotate. Under the meshing action of the gear 1 5 and the meshing teeth 13, the gear 1 5 drives the transmission shaft 51 and the cam 52 to rotate, and the transmission shaft 51 drives the threaded segment 511 to rotate. Under the action of the spring 1 32, the baffle 3 and the threaded segment 511 always maintain an abutment state, so that when the threaded segment 511 rotates, under the action of the thread cooperation, the baffle 3 moves closer to each other along the threaded segment 511. When the baffle 3 moves to the light rod segment 512 on the side away from the gear 1 5, the spring 1 32 is in a compressed state. At this time, the baffle 3 closes the feed hopper 2 to prevent the sample from splashing out. At the same time, the baffle 3 drives the top end of the rope 31 to move closer together, so that the turntable 22 drives the baffle 3 to rotate, and the rope 31 is pressed. The rope 31 is twisted, so that the twisting force causes the rope 31 to cut the flesh and finally wrap the core, thereby intercepting the core above the receiving bucket 4, and the flesh is squeezed and falls into the receiving bucket 4 through the gap between the ropes 31, thereby achieving the effect of core removal. At the same time, under the action of the separation mechanism, the scraping column 63 can squeeze and crush the sample to a certain extent, thereby improving the liquid output rate of the sample, and at the same time facilitating the rope 31 to cut the flesh and wrap the core, and the floating frame 6 drives the scraping column 63 to move up and down reciprocatingly, thereby achieving the effect of scraping the sample, and can scrape off the residual flesh on the core, thereby improving the utilization rate of the sample. Under the action of the squeezing mechanism, the roller 65 can squeeze the flesh on the filter plate 41 during rotation. When discharging, the handle 72 is pulled outward. Under the action of the discharging mechanism, the filter plate 7 drives the avoidance groove 73 to rotate to align with the filter hole of the filter plate 41, thereby allowing the core to be discharged through the filter hole of the filter plate 41.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
