Several placement slots are fixedly connected at equal intervals along the circumference of the conveyor belt. Adjustable components are provided at both ends of each placement slot. Adjustable plates are provided on both sides of the worktable. One end of each adjustable component extends into the placement slot through the adjustment plate and is fitted with a limiting component. The two limiting components are used to clamp the jujubes. The ejector rod is used to eject the jujube pits. A collection component includes a cleaning component and two collection slots. The two collection slots are respectively located inside and below the conveyor belt. The two collection slots are used to collect jujube pits and jujubes respectively. The cleaning component is located in the collection slot inside the conveyor belt and is used to remove the jujube pits ejected by the ejector rod. This utility model has a simple structure, ensures the stability of the jujube pitting process, avoids jujube detachment and pit adhesion, and improves pitting efficiency.

[0004] In actual use, the above scheme can only process one jujube per cylinder operation, which will result in a large waste of electricity and low processing efficiency in the long run. Utility Model Content

[0005] This utility model discloses a device for removing the pits and flesh from jujubes, which aims to solve the technical problem of low pitting efficiency in existing jujube pitting devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for removing pits and pulp from jujubes includes a base, a stepper motor is embedded inside the housing of the base, the output shaft of the stepper motor extends to the upper surface of the base and is fixedly mounted on an mounting plate, and a feeding cylinder and a top plate are fixedly mounted on the upper surface of the base through a support frame, with the lower surface of the feeding cylinder overlapping the upper surface of the mounting plate.

[0008] The surface of the mounting plate is provided with several jujube-holding grooves arranged in a circular array. A horizontal plate is fixedly connected to the inner wall of the feeding cylinder. A servo motor is fixedly installed on the upper surface of the horizontal plate. The output shaft of the servo motor extends to the bottom of the horizontal plate and is fixedly installed with a push plate.

[0009] An electric hydraulic cylinder is embedded in the upper surface of the top plate. A pressure plate is fixedly installed on the telescopic end of the electric hydraulic cylinder. The lower surface of the pressure plate is provided with a number of core rods corresponding to a number of jujube-placement slots. The shell of the base is provided with a core collection slot and a material collection slot. The core collection slot and the material collection slot are slidably connected to a first collection box and a second collection box through slide rails. The upper surface of the base is provided with a number of core removal holes that are adapted to a number of core rods and communicate with the interior of the core collection slot. The upper surface of the base is provided with a material discharge opening that penetrates into the interior of the material collection slot.

[0010] In a preferred embodiment, the number of push plates is four, which are arranged in a circular array on the surface of the servo motor output shaft, and the push plates overlap with the surface of the mounting plate.

[0011] The push plate can push the jujubes in the feeding cylinder into the jujube placing trough.

[0012] In a preferred embodiment, the aperture of the jujube-holding groove is adapted to the size of the jujube, and the diameter of the core rod and the aperture of the pitting hole are both adapted to the size of the jujube pit.

[0013] In a preferred embodiment, the side of the base is rotatably connected via a rotating seat to a limiting block for restricting the first collection box and the second collection box.

[0014] In a preferred embodiment, the housing of the feeding cylinder has an annular air chamber inside, a hot air blower is embedded in the side of the base, the air outlet of the hot air blower extends into the interior of the annular air chamber, and the inner wall of the annular air chamber has an air outlet hole that penetrates into the interior of the feeding cylinder.

[0015] By using a hot air blower and air outlet, the jujubes in the feeding cylinder can be dried to remove moisture.

[0016] In a preferred embodiment, the number of air outlets is several, and the several air outlets are arranged in a circular array on the inner wall of the annular air cavity.

[0017] As can be seen from the above, the jujube pitting and flesh removal device provided by this utility model has the following technical effects.

[0018] Firstly, the stepper motor drives the mounting plate to rotate, moving several jujube-placement slots below the feeding cylinder. This causes the jujubes in the feeding cylinder to fall into the jujube-placement slots. As the stepper motor runs again, the mounting plate rotates, moving the jujube-placement slots below the pressure plate. Under the operation of the electric hydraulic cylinder, the pressure plate drives several core rods to move downwards, inserting the jujube pits through the pitting holes into the first collection box. At this time, as the stepper motor runs again, the de-pitted jujubes in the jujube-placement slots fall into the second collection box through the discharge opening. This process is repeated to achieve continuous pitting. The principle is simple, and the pitting efficiency is high.

[0019] Secondly, the hot air blown into the annular air chamber by the hot air blower and blown out through several air outlets can dry the jujubes in the feeding cylinder, remove the water stains left on their surface due to cleaning, and facilitate the subsequent processing steps after the jujubes are pitted.

The output shaft of the stepper motor 2 extends to the upper surface of the base 1 and is fixedly mounted on an mounting plate 3. A feeding cylinder 4 and a top plate 5 are fixedly mounted on the upper surface of the base 1 through a support frame. The lower surface of the feeding cylinder 4 overlaps with the upper surface of the mounting plate 3.

[0028] The surface of the mounting plate 3 has several jujube-placement grooves 6 arranged in a circular array. A horizontal plate is fixedly connected to the inner wall of the feeding cylinder 4. A servo motor 7 is fixedly installed on the upper surface of the horizontal plate. The output shaft of the servo motor 7 extends to the bottom of the horizontal plate and is fixedly installed with a push plate 8.

[0029] There are four push plates 8, which are arranged in a circular array on the surface of the output shaft of the servo motor 7. The push plates 8 overlap with the surface of the mounting plate 3. By setting the push plates 8, the jujubes in the feeding cylinder 4 can be pushed into the jujube placing trough 6.

[0030] An electric hydraulic cylinder 9 is embedded in the upper surface of the top plate 5. A pressure plate 10 is fixedly installed on the telescopic end of the electric hydraulic cylinder 9. A number of core rods 11 are provided on the lower surface of the pressure plate 10, which correspond to the positions of a number of jujube-placement grooves 6. A core-collecting groove and a material-collecting groove are respectively opened inside the housing of the base 1. The core-collecting groove and the material-collecting groove are slidably connected to a first collection box 12 and a second collection box 13 through slide rails. A number of core-removing holes 14 are opened on the upper surface of the base 1, which are adapted to the number of core rods 11, and the core-removing holes 14 are connected to the interior of the core-collecting groove. A material-dropping opening 15 is opened on the upper surface of the base 1, which penetrates into the interior of the material-collecting groove.

[0031] By controlling the number of revolutions of the stepper motor 2, it drives the mounting plate 3 to rotate intermittently when it reaches the feeding cylinder 4, the pressure plate 10, and the discharge opening 15.

[0032] The diameter of the jujube-holding groove 6 is matched to the size of the jujube, and the diameter of the core rod 11 and the diameter of the pitting hole 14 are matched to the size of the jujube pit.

[0033] The side of the base 1 is rotatably connected to a limiting block 16 for limiting the first collection box 12 and the second collection box 13 via a rotating seat.

[0034] Reference Figure 3 In a preferred embodiment, an annular air chamber 17 is provided inside the housing of the feeding cylinder 4, and a hot air blower 18 is embedded in the side of the base 1. The air outlet of the hot air blower 18 extends into the interior of the annular air chamber 17, and an air outlet hole penetrating into the interior of the feeding cylinder 4 is provided on the inner wall of the annular air chamber 17.

[0035] There are several air outlets, which are arranged in a circular array on the inner wall of the annular air chamber 17.

[0036] By using the hot air blower 18 and the air outlet, the jujubes in the feeding cylinder 4 can be dried to remove moisture.

[0037] Working principle: During use, the pitted jujubes are poured into the feeding cylinder 4. Then, the stepper motor 2 drives the mounting plate 3 to rotate until several jujube-placement slots 6 on the surface of the mounting plate 3 move below the feeding cylinder 4. At this point, the servo motor 7 drives the push plate 8 to rotate slowly. The rotation of the push plate 8 pushes the jujubes in the feeding cylinder 4 into the several jujube-placement slots 6, completing the feeding process. With the stepper motor 2 running again, the mounting plate 3 rotates, moving the jujube-placement slots 6 below the pressure plate 10. Under the operation of the electric hydraulic cylinder 9, the pressure plate 10 drives several core rods 11 to move downwards. The downward movement of the core rods 11... The pits of the jujubes are inserted into the first collection box 12 through the pitting hole 14, while the pitted jujubes, unable to pass through the pitting hole 14, remain in the jujube placement trough 6. As the stepper motor 2 runs, when the mounting plate 3 rotates to the discharge opening 15, the pitted jujubes in the jujube placement trough 6 fall into the second collection box 13 through the discharge opening 15. This process is repeated to achieve continuous pitting. At the same time, hot air is blown into the annular air chamber 17 by the hot air blower 18 and blown out through several air outlets to dry the jujubes in the feeding cylinder 4 and remove the water stains remaining on their surface due to washing.
