Description

Technical Field

[0001] This invention relates to the field of separation equipment, specifically a device for separating jujube kernels and flesh. Background Technology

[0002] Sour jujube kernel is the seed kernel obtained by cracking the shell of the sour jujube fruit after removing the pulp. It has calming and sleep-aiding effects, as well as heart-nourishing and sweat-reducing properties, and is an important raw material in the production of traditional Chinese medicine decoction pieces, health foods, and functional foods. With the increasing market demand for sour jujube kernel, its processing methods are gradually shifting from traditional manual processing to mechanization and automation. In the production process, the sour jujube kernel usually needs to be cracked first to expose the kernel inside the shell, and then the kernel is separated from the shell fragments. Due to the high hardness of the sour jujube kernel, to ensure the integrity of the kernel, most existing cracking equipment uses extrusion crushing or roller crushing methods. The material after cracking usually contains whole sour jujube kernels, half-kernel kernels, shell fragments, and some incompletely separated shell-kernel composites. Therefore, specialized separation equipment is needed for screening and purification to improve the quality of the sour jujube kernel product and the efficiency of subsequent processing.

[0003] Currently, when separating jujube kernels from shell fragments, some jujube kernels still have shell fragments attached to their surface, making it difficult to achieve complete separation during sieving. This easily results in a mixture of kernels and shells and low purity of jujube kernels, thus affecting the quality of jujube kernel-meat separation. There is an urgent need for a feeding mechanism that can solve the above problems. Summary of the Invention

[0007] Preferably, the conveying component includes: The mounting frame is fixedly connected to the top surface of the collection box, and two guide blocks are fixedly connected to the top surface of the mounting frame; The discharge port is located on one side of the separation box.

[0008] Preferably, the top surface of the placement platform is provided with a conveying groove, and a conveying plate is fixedly connected inside the conveying groove. The top surface of the conveying plate is fixedly connected to the bottom surface of the collection box. A conveying hole is provided on one side of the placement box, and a guide pipe is fixedly connected inside the conveying hole.

[0009] Preferably, two mounting boxes are fixedly connected to the bottom surface inside the collection box, the top of the mounting box is fixedly connected to the bottom surface of the screen, and a vibration motor is fixedly connected inside the mounting box.

[0010] Preferably, the driving component includes: A rotating hole is provided, which is located on one side inside the separation box, and a rotating rod is rotatably mounted inside the rotating hole. A plurality of stirring blades are fixedly connected at equal angles to the outer wall of the rotating rod. A drive hole is provided on one side of the placement box, and the rotating rod is rotatably mounted together with the drive hole. A cleaning component, disposed on the outside of the placement box, is used to clean the placement box.

[0011] Preferably, the cleaning component includes: Two cleaning holes are respectively opened on the left and right sides of the placement box. A protective plate is movably fitted inside the cleaning hole. A hinge is fixedly connected to one side of the protective plate, and one side of the hinge is fixedly connected to one side of the placement box. Two grips, both of which are fixedly attached to one side of the protective plate.

[0012] Preferably, a mounting box is fixedly connected to the top surface of the placement platform, a drive motor is fixedly connected inside the mounting box, a control hole is opened on one side of the mounting box, a rotating shaft is rotatably installed inside the control hole, a connecting wheel is fixedly connected to one end of the rotating shaft and one end of the rotating rod, and a transmission belt is rotatably installed between the two connecting wheels.

[0013] Preferably, the two connecting wheels are movably fitted with protective covers, and a positioning rod is fixedly connected to one side of the protective cover. Positioning grooves are provided on one side of the mounting box and one side of the placement box. The positioning rod is movably fitted with the positioning groove.

[0014] Preferably, support blocks are fixedly connected to the four corners of the bottom surface of the placement platform, and support legs are connected to the internal threads of the support blocks, and nuts are connected to the external threads of the support legs.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a placement platform, the platform is first installed in a suitable position. Then, the crushed jujube pit raw material is fed into the hopper, allowing it to enter the placement box through the feed hole. Simultaneously, the jujube pit raw material first enters the separation box. The jujube pit raw material in the separation box is repeatedly stirred by the drive component, so that the shell and kernel can be completely separated, avoiding the presence of shell fragments still attached to the surface of some jujube kernels. During the stirring process, the mixture of kernels and smaller shells flows out through the separation hole, while the larger shells can accumulate inside the separation box, thus achieving the initial separation effect.

[0016] 2. By installing a vibration motor, the motor can simultaneously drive the screen and the collection box to vibrate at high frequency through the mounting box. This prevents kernel and shell debris from clogging the screen mesh and improves screening efficiency. At the same time, it enhances the stratification effect of the mixture, causing shell debris attached to the surface of the kernel to fall off under the vibration, further improving the purity of the kernel. Meanwhile, the kernels screened by the screen can fall onto the conveyor plate through the through holes, allowing the conveyor plate to transport the kernel meat. Under the vibration of the mounting box, the kernel shells gradually move towards one end of the guide pipe and are discharged through the guide pipe, thus preventing the long-term accumulation of kernel shells from affecting the screening effect.

[0017] 3. By setting up a drive motor, due to the synchronous transmission of the two connecting wheels and the transmission belt, when the drive shaft of the drive motor drives the two connecting wheels to rotate through the rotating shaft, the rotating rod and stirring blade can operate, providing power for the initial separation of the shell and kernel. At this time, the protective cover is inserted into the positioning groove by the positioning rod, which can protect the transmission belt and prevent foreign objects from being drawn in, ensuring drive stability. The placement platform is moved as a whole by universal wheels. When the placement platform reaches the designated position, the support legs are rotated and locked with nuts, thereby leveling and supporting the placement platform, reducing the displacement of the placement platform due to vibration during operation.

Detailed Implementation

[0020] Please see Figures 1-9 According to an embodiment of the present invention, a jujube pit and kernel separation device includes: a placement platform 1, a placement box 2 fixedly connected to the top surface of the placement platform 1, and a feeding hole 3 opened on the top surface of the placement box 2; a feeding hopper 4 fixedly connected inside the feeding hole 3, a separation box 5 fixedly connected inside the placement box 2, and a plurality of separation holes 6 opened on the inner wall surface of the separation box 5; a through hole 7 opened on the bottom surface inside the placement box 2; a separation component, the separation component being disposed inside the through hole 7, used for separating the pit shell and kernel; a driving component, the driving component being disposed inside the separation box 5, used for driving the pit shell and kernel, the separation component including: a collection box 8 fixedly connected inside the through hole 7, a screen 9 fixedly connected inside the collection box 8; a baffle 10 fixedly connected to the top surface of the screen 9, one side of the baffle 10 being fixedly connected to the outer wall surface of the separation box 5; and a conveying component, the conveying component being disposed on the top surface of the collection box 8, used for conveying the pit shell; By setting up a placement platform 1, the platform is first installed in a suitable position. Then, the crushed jujube pit raw material is fed into the hopper 4, allowing it to enter the placement box 2 through the feed hole 3. Simultaneously, the jujube pit raw material first enters the separation box 5. The driving component repeatedly stirs the jujube pit raw material in the separation box 5, ensuring complete separation of the shell and kernel, preventing shell fragments from remaining on the surface of some jujube kernels. During the stirring process, the mixture of kernel and smaller shells flows out through the separation hole 6, while the larger shells accumulate inside the separation box 5, achieving a preliminary separation effect. At the same time, some smaller shells and kernels fall directly onto the screen 9 below. The smaller, finely crushed shells can then directly enter the collection box 8 through the screen 9, allowing for simultaneous screening of both smaller and larger shells. Meanwhile, the shells accumulated inside the separation box 5 can enter the collection box 8 through a conveyor, enabling the centralized collection of the screened shells.

[0021] exist Figures 2-5 The conveying components include: a mounting frame 11, which is fixedly connected to the top surface of the collection box 8, and two guide blocks 12 are fixedly connected to the top surface of the mounting frame 11; a discharge hole 13, which is opened on one side of the separation box 5; a conveying trough 14 is opened on the top surface of the placement platform 1, and a conveying plate 15 is fixedly connected inside the conveying trough 14, and the top surface of the conveying plate 15 is fixedly connected to the bottom surface of the collection box 8; a conveying hole 16 is opened on one side of the placement box 2, and a guide pipe 17 is fixedly connected inside the conveying hole 16; two mounting boxes 18 are fixedly connected to the bottom surface of the collection box 8, and the top of the mounting box 18 is fixedly connected to the bottom surface of the screen 9, and a vibrating motor 19 is fixedly connected inside the mounting box 18; By setting the guide block 12, when the larger kernel shell inside the separation box 5 rotates, since the separation box 5 is in an inclined state, the kernel shell will gradually move towards the bottom of the separation box 5 and enter between the two guide blocks 12 through the discharge hole 13. This allows the kernel shell flowing out of the separation box 5 to enter the collection box 8 through the mounting frame 11, achieving basic separation of the kernel and the kernel shell. By setting the vibration motor 19, the vibration motor 19 can simultaneously drive the screen 9 and the collection box 8 to vibrate at high frequency through the mounting box 18, thereby preventing... The screen 9 is designed to prevent kernel and shell fragments from clogging the mesh, thus improving screening efficiency. It also enhances the stratification effect of the mixture, causing shell fragments attached to the surface of the kernel to fall off under vibration, further improving the purity of the kernel. Meanwhile, the kernels screened by the screen 9 can fall onto the conveyor plate 15 through the through hole 7, allowing the conveyor plate 15 to transport the kernel meat. Under the vibration of the mounting box 18, the kernel shells gradually move towards one end of the guide pipe 17 and are discharged through the guide pipe 17, thereby preventing the long-term accumulation of kernel shells from affecting the screening effect.

[0022] exist Figures 2-7 The driving component includes: a rotating hole 20, which is located on one side inside the separation box 5, and a rotating rod 21 is rotatably mounted inside the rotating hole 20; several stirring blades 22, which are fixedly connected to the outer wall of the rotating rod 21 at equal angles; a driving hole 23 is provided on one side of the placement box 2, and the rotating rod 21 is rotatably mounted together with the driving hole 23; a cleaning component, which is located outside the placement box 2 and is used to clean the placement box 2. The cleaning component includes two cleaning holes 24, which are respectively located on the left and right sides of the placement box 2. A protective plate 25 is movably fitted inside the cleaning holes 24. A hinge 26 is fixedly connected to one side of the protective plate 25, and one side of the hinge 26 is fixedly connected to one side of the placement box 2; and two handles 27, which are both fixedly connected to one side of the protective plate 25. By setting a rotating rod 21, when the rotating rod 21 rotates, it can drive several stirring blades 22 to rotate, thereby initially separating the core shell and core meat in the separation box 5. By setting a protective plate 25, when the protective plate 25 is opened by the hinge 26, the staff can directly clean and repair the equipment inside the placement box 2.

[0023] exist Figures 6-9In the middle: The top surface of the placement platform 1 is fixedly connected to the mounting box 28. The inside of the mounting box 28 is fixedly connected to the drive motor 29. A control hole 30 is opened on one side of the mounting box 28. A rotating shaft 31 is rotatably installed inside the control hole 30. One end of the rotating shaft 31 and one end of the rotating rod 21 are both fixedly connected to the connecting wheel 32. A transmission belt 33 is rotatably installed between the two connecting wheels 32. A protective cover 34 is movably sleeved on the outside of the two connecting wheels 32. A positioning rod 35 is fixedly connected to one side of the protective cover 34. A positioning groove 36 is opened on one side of the mounting box 28 and one side of the placement box 2. The positioning rod 35 and the positioning groove 36 are movably sleeved together. Several universal wheels 37 are fixedly connected to the bottom surface of the placement platform 1. Support blocks 38 are fixedly connected to the four corners of the bottom surface of the placement platform 1. Support legs 39 are threaded inside the support blocks 38. The inner wall of the support blocks 38 and the outer wall of the support legs 39 are both threaded. Nuts 40 are threaded on the outside of the support legs 39. By setting up a drive motor 29, due to the synchronous transmission of the two connecting wheels 32 and the transmission belt 33, when the drive shaft of the drive motor 29 drives the two connecting wheels 32 to rotate through the rotating shaft 31, the rotating rod 21 and the stirring blade 22 can operate, providing power for the initial separation of the kernel and shell. At that time, the protective cover 34 is inserted into the positioning groove 36 through the positioning rod 35, which can protect the transmission belt 33 and prevent foreign objects from being drawn in, ensuring drive stability. The placement platform 1 is moved as a whole through the universal wheels 37. When the placement platform 1 reaches the designated position, the rotating support leg 39 is locked with the nut 40, thereby leveling and supporting the placement platform 1, reducing the displacement of the placement platform 1 due to vibration during operation, and ensuring that the screen 9 is in an inclined state, thereby separating the kernel and shell.

[0024] The working principle of this invention is as follows: First, the placement platform 1 is moved as a whole using the casters 37. After the placement platform 1 reaches the designated position, the support leg 39 is rotated and locked with the nut 40, thereby leveling and supporting the placement platform 1 and reducing displacement due to vibration during operation. Then, the crushed jujube pit raw material is fed into the hopper 4, allowing it to enter the placement box 2 through the feed hole 3. Simultaneously, the jujube pit raw material first enters the separation box 5, and then the drive motor 29 is started. Due to the synchronous transmission of the two connecting wheels 32 and the transmission belt 33, when the drive shaft of the drive motor 29 drives the two connecting wheels 32 to rotate through the rotating shaft 31, the rotating rod 21 and the stirring blade 22 can operate. At this time, the kernel and small shells flow out through the separation hole 6, and the larger shells can accumulate inside the separation box 5, thus achieving a preliminary separation effect. At the same time, some of the smaller shells and kernels fall directly into the screen 9 below. Above: Restart the vibration motor 19. The vibration motor 19 can simultaneously drive the screen 9 and the collection box 8 to vibrate at high frequency through the mounting box 18, thereby preventing kernel and shell debris from clogging the mesh of the screen 9 and improving screening efficiency. At the same time, it enhances the stratification effect of the mixture, causing the shell debris attached to the surface of the kernel to fall off under the vibration, further improving the purity of the kernel. Meanwhile, the kernels screened by the screen 9 can fall above the conveyor plate 15 through the through hole 7, so that the conveyor plate 15 can transport the kernel meat. Under the vibration of the mounting box 18, the kernel shell gradually moves towards one end of the guide pipe 17 and is discharged through the guide pipe 17, thereby preventing the long-term accumulation of kernel shells from affecting the screening effect. Since the separation box 5 is in an inclined state, the kernel shell will gradually move towards the bottom of the separation box 5 and enter between the two guide blocks 12 through the discharge hole 13, so that the kernel shell flowing out of the separation box 5 can enter the interior of the collection box 8 through the mounting frame 11, realizing the separation of kernel and kernel shell.
