Description

Technical Field

[0001] The present invention relates to the technical field of fruit core and pulp separation, and particularly to a continuous fruit core processing device. Background Art

[0002] The entire process of picking ginkgo fruits, soaking them in water to remove the outer pulp skin, and drying the fruits is not only cumbersome, but also the outer pulp skin emits a pungent odor. To avoid excessive manual participation, corresponding automated separation devices are required. Currently, there are automated devices that can separate the fruit skin from the fruit.

[0003] For example, the Chinese patent with the application number CN201711393993.3 discloses a continuous automatic fruit core separator, which includes a frame, a fruit picking module, a fruit feeding module, a fruit core removing module, and a pulp conveying and detecting module. The fruit picking module transports multiple fruits to the fruit feeding module, and the fruit feeding module arranges the fruits in a single-piece (grain) manner and places them in the fruit core removing module for seed removal and core removal operations, and sends the seeded pulp to the pulp conveying and detecting module. With the concept of automation, the work of fruit seed removal and core removal is completely handed over to mechanical automation production. However, during the seed removal and core removal process, it peels the fruits by the way of approaching and colliding with each other. The linear velocity in the central area of the eddy current is relatively low, which will cause some outer pulp to adhere to the fruit core and the separation is not complete. While the linear velocity at the edge of the eddy current is relatively high, which can produce a stronger peeling effect and will cause excessive damage to the internal fruit core. Summary of the Invention

[0043] The first embodiment of the present invention proposes a continuous fruit pit processing device, such asFigures 1-9 As shown, the device comprises a frame 1, a cleaning frame 2 arranged in the frame 1 and a screen 3 installed in the cleaning frame 2, and the device also comprises:

[0044] A lifting frame 4 and a lifting part for driving the lifting frame 4 to perform lifting motion in the frame 1;

[0045] A first stepper motor 5 fixed on the lifting frame 4 and a rocker arm 6 with one end fixed on the output shaft of the first stepper motor 5;

[0046] A stirring rod 7 whose top end is rotatably connected to the other end of the rocker arm 6, and whose bottom end is used to extend into the cleaning frame 2 when the cleaning frame 2 is located directly below the lifting frame 4;

[0047] A rotating shaft 8 whose end is rotatably connected to one side of the lifting frame 4;

[0048] A water-passing box 9 is arranged on the rotating shaft 8. The water-passing box 9 is a 匚-shaped structure with a central cavity. The stirring rod 7 passes through the central cavity of the water-passing box 9. The stirring rod 7 contacts the inner wall of the cavity of the water-passing box 9, and the central part of the stirring rod 7 is rotatably arranged on the upper part of the water-passing box 9 through a ball 10.

[0049] The water spray head 11 is arranged at the bottom of the water box 9 and is arranged tilted so that when the cleaning frame 2 is located directly below the lifting frame 4, the water spraying direction of the water spray head 11 is toward the central axis of the cleaning frame 2.

[0050] In this embodiment, when in use, the output end of the first stepper motor 5 drives the rocker arm 6 to rotate, and then drives the stirring rod 7 to rotate around the ball 10. The stirring rod 7 can revolve around the output shaft of the first stepper motor 5, and can perform preliminary peeling and continuous stirring of the fruits on the screen 3. At the same time, the stirring rod 7 can also rotate around its own axis to further enhance the peeling effect of the fruits on the screen 3. The stirring rod 7 can also push the inner wall of the cavity of the water box 9 during the rotation process, so that the water box 9 reciprocates around the rotating shaft 8, so that the water spray head 11 obliquely arranged at the lower end is synchronously flipped to push the fruits gathered in the middle of the cleaning frame 2 to both sides again;

[0051] It can be achieved that: as the stirring continues, small-volume fruits with relatively small diameters and incomplete peeling will gradually move closer to the middle area of ​​the cleaning frame 2; at the same time, since the water spray heads 11 also synchronously reciprocate, several water spray heads 11 facing the middle of the cleaning frame 2 can push the fruits close to the middle of the cleaning frame 2, that is, push small-volume fruits with relatively small diameters and incomplete peeling back to the stirring area of ​​the stirring rod 7. During the peeling process, the outer layer of pulp is discharged through the screen 3.

[0052] In this embodiment, if Figure 3As shown, the device further includes a support column 12 fixed in the frame 1 , and the lifting frame 4 is slidably connected to the support column 12 .

[0053] In this embodiment, if Figure 4 As shown, a drying barrel 15 is provided in the frame 1, and a serpentine heating tube 16 is installed in the drying barrel 15. The heating tube 16 in the drying barrel 15 is used to continuously dry the fruit cores in the cleaning frame 2.

[0057] A lead screw 18 is provided on the output end of the second stepper motor 17, and the lifting frame 4 is threadedly installed on the lead screw 18; the output end of the second stepper motor 17 drives the lead screw 18 to rotate, and then drives the lifting frame 4 to move up and down. The descending process will drive the stirring rod 7 to move to the stirring area of ​​the cleaning frame 2, and the ascending process will drive the stirring rod 7 to leave the cleaning frame 2.

[0058] In this embodiment, if Figure 4 , Figure 6 , Figure 7 As shown, a drainage pump 19 is provided at the lower part of the cleaning frame 2, and a screw 20 for cleaning the inlet of the drainage pump 19 is also provided inside the cleaning frame 2. The screw 20 is driven by a driving part, and the outer layer of pulp leaking from the screen 3 is finally extracted by the drainage pump 19.

[0059] In this embodiment, if Figure 4 , Figure 6 , Figure 7 As shown, the driving unit includes:

[0060] A cylinder 21 disposed in the frame 1;

[0061] A push rod 22 is arranged at the output end of the cylinder 21, and one end of the screw rod 20 is rotatably arranged at the other side of the push rod 22;

[0062] A guide frame 23 is arranged in the frame 1, and a rotating rod 24 is rotatably arranged on the guide frame 23;

[0063] A slide bar 25 slidably disposed on the guide frame 23, the slide bar 25 being connected to the rotating bar 24 via a slider;

[0064] The push-pull seat 26 is slidably arranged on the guide frame 23. One end of the push-pull seat 26 is slidably connected to the rotating rod 24, and the other end of the push-pull seat 26 is connected to the screen 3. Specifically: the output end of the air cylinder 21 drives the ejector rod 22 to move forward, and through the cleaning frame 2, the screw rod 20 is rotated forward, so as to clean the pulp at the inlet of the drainage pump 19 to prevent blockage. At the same time, the ejector rod 22 also drives the sliding rod 25 to slide on the guide frame 23. Under the action of the rotating rod 24 and the corresponding slider, the screen 3 is driven by the push-pull seat 26 to lift and slide in the cleaning frame 2, so as to synchronously achieve the purpose of anti-blocking and secondary soaking treatment of the fruits on the screen 3.

[0065] In this embodiment, as Figure 1 shown, a conveyor belt 28 is provided at the inlet of the frame 1. The top of the conveyor belt 28 faces the cleaning frame 2 to achieve automatic feeding. A sliding door 29 is provided at the side end of the frame 1. The opening of the sliding door 29 faces the cleaning frame 2. After drying is completed, the sliding door 29 is opened, and the dried fruit cores can be manually taken out from the cleaning frame 2.

[0066] The present invention also proposes a second embodiment. The only difference from the first embodiment is that, as Figure 8 shown, a liftable inner rod 27 is slidably arranged in the stirring rod 7. A scraping head 30 is provided at the lower end of the inner rod 27. The scraping head 30 is matched with the outer surface of the end of the stirring rod 7. By the forward and reverse rotation of the output end of the first stepping motor 5 and through the bevel gear transmission structure, that is, one side of the bevel gear is fixedly arranged on the lifting frame 4 as a fixed bevel gear, and the meshing bevel gear on the other side is rotatably arranged on the swing arm 6 as a moving bevel gear. The rotation of the swing arm 6 drives the moving bevel gear to rotate around the output shaft of the first stepping motor 5. An inner screw rod coaxial with the moving bevel gear is arranged in the stirring rod 7. The inner rod 27 is threaded on the inner screw rod. The inner rod 27 is limited to slide in the opening of the stirring rod 7, and then drives the inner rod 27 to reciprocate up and down in the stirring rod 7, so as to realize the timely cleaning of the outer surface of the end of the stirring rod 7 by the scraping head 30.

[0067] The present invention also proposes a third embodiment. The only difference from the first embodiment is that, as Figure 9 shown, an externally threaded rod 31 that can be lifted is threaded in the stirring rod 7. A scraping member 32 is provided at the lower end of the externally threaded rod 31. The scraping member 32 is matched with the outer surface of the end of the stirring rod 7. By the forward and reverse rotation of the output end of the first stepping motor 5 and through the bevel gear transmission structure (the bevel gear transmission structure here is the same as that in the second embodiment), the rotation of the swing arm 6 drives the moving bevel gear to rotate around the output shaft of the first stepping motor 5. The moving bevel gear is coaxially fixed with the stirring rod 7, and the moving bevel gear also drives the stirring rod 7 to rotate. The externally threaded rod 31 is threadedly connected to the moving bevel gear, and the externally threaded rod 31 is rotatably connected to the scraping member 32, and then the externally threaded rod 31 can be driven to reciprocate up and down in the stirring rod 7, so as to realize the timely cleaning of the outer surface of the end of the rotating stirring rod 7 by the scraping member 32.
