Description

Technical Field

[0001] This invention relates to the field of jujube kernel processing technology, and in particular to a clean dehulling processing device for jujube kernels based on a peeling structure. Background Technology

[0002] As a commonly used traditional Chinese medicine, the shell of the Chinese jujube seed is hard and needs to be removed before the kernel can be processed. The shelling process is a key step in the processing of Chinese jujube seeds, directly affecting the integrity and cleanliness of the kernel and the efficiency of subsequent processing. Therefore, efficient and clean shelling equipment is particularly important for the Chinese jujube seed industry.

[0003] Currently, shelling of jujube kernels in southern China primarily relies on manual tapping, using external force to break the outer shell and separate the kernel. This method is not only time-consuming and labor-intensive, resulting in high labor costs, but also has significant drawbacks: firstly, the tapping force is difficult to control precisely, easily leading to damage to the kernel and reducing product quality; secondly, impurities are easily introduced during manual operation, making it impossible to guarantee the cleanliness of the shelling process. Furthermore, existing technology does not classify jujube kernels of different sizes, and uniform shelling easily leads to excessive compression and damage to small-diameter kernels, while large-diameter kernels are not completely shelled, further affecting processing quality and efficiency.

[0004] Based on this, a clean dehulling processing device for jujube kernels based on a peeling structure is proposed. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-5 The present invention provides a technical solution:

[0027] A clean shelling and processing device for jujube kernels based on a shelling structure includes a processing chamber 1. A support column 2 is connected to the lower end of the processing chamber 1 to improve the overall operational stability of the device. A collection door 18 is rotatably connected to the processing chamber 1, allowing for the periodic collection of shelled jujube kernels within the processing chamber 1. A screw 23 is slidably connected to the processing chamber 1, with an extrusion plate 29 connected to one end of the screw 23. The extrusion plate 29 is positioned inside the processing chamber 1, and by moving closer together, it extrudes and shells the jujube kernels. A screw 23 is connected to... The processing chamber 1 has a synchronous frame 17 and a middle shaft 22 connected to its lower end. The middle shaft 22 is vertically connected to the lower end of the processing chamber 1. A rotating plate 20 is rotatably connected to the middle shaft 22. A pull bar 19 is rotatably connected to both ends of the rotating plate 20. The other end of the pull bar 19 is rotatably connected to the synchronous frame 17. By rotating the rotating plate 20, the synchronous frames 17 on both sides of the processing chamber 1 can be pulled closer or further apart. A transmission component is connected to one side of the rotating plate 20 to drive the rotating plate 20 to reciprocate. The processing chamber 1 has a separation mechanism connected to its upper end for separating jujube kernels of different particle sizes before dehulling.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, a horizontal plate 16 is connected to the upper end of the extrusion plate 29. The horizontal plate 16 is connected through the processing chamber 1. The horizontal plate 16 and the extrusion plate 29 are perpendicular to each other. The horizontal plate 16 can prevent the date pits from falling into the non-shelling area of ​​the processing chamber 1.

[0029] Specifically, such as Figure 4 As shown, a spring 30 is connected to the extrusion plate 29, and the other end of the spring 30 is connected to the inner wall of the processing chamber 1. The spring 30 is sleeved on the screw 23. By setting the spring 30, the extrusion plate 29 can automatically reset its structure after the date pit is deshelled, thus improving the smoothness of the transmission of the rotating plate 20.

[0030] Specifically, such as Figure 4 As shown, the timing frame 17 is slidably connected to the screw 23, and the screw 23 is threaded with a nut 24. The nut 24 abuts against the timing frame 17. By setting the cooperation between the nut 24 and the screw 23, the connection position of the extrusion plate 29 can be adjusted, thereby realizing the adjustment of different clamping distances, so that different chambers inside the processing chamber 1 can perform different shelling operations, thus adapting to different sizes of date pits.

[0031] Specifically, such as Figure 1 and Figure 3As shown, the transmission components include a motor 6, which is connected to one side of the processing chamber 1 via a fixing hoop 7. One end of the fixing hoop 7 is connected to the inclined frame 26. The output end of the motor 6 is connected to a drive wheel 25, which is connected to a driven wheel 13 via a belt 14. The drive wheel 25 and the driven wheel 13 rotate synchronously. A bevel gear 12 is connected to one side of the driven wheel 13, and a shaft frame 10 is connected to one side of the processing chamber 1. The driven wheel 13 is rotatably connected to the shaft frame 10, and a bevel gear 11 is rotatably connected to the shaft frame 10. The bevel gear 11 and the bevel gear 12 mesh with each other. A traction bar 15 is eccentrically rotatably connected to the bevel gear 11, and a deflection bar 21 is rotatably connected to the other end of the traction bar 15. The deflection bar 21 is connected to the lower end of the rotating plate 20. The rotation of the bevel gear 11 can push the traction bar 15 to move, and the traction bar 15 can drive the rotating plate 20 to reciprocate.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, the separation mechanism includes a sorting bin 4, on which a feeding trough 31 is provided. The processing bin 1 is connected to a partition 34 and a collection door 18. By setting the partition 34, the area within the sorting bin 4 can be divided, thereby achieving targeted shelling operations. The number of partitions 34 can be set according to actual processing needs, and is not limited to one. By increasing the number of partitions 34, the chamber division within the processing bin 1 can be further refined, allowing jujube kernels of different particle sizes to enter their respective dedicated chambers for shelling, thereby achieving a more refined shelling effect.

[0033] The sorting bin 4 is fixedly connected above the processing bin 1. A slant frame 26 is connected to one side of the sorting bin 4. A guide shaft 32 is connected to one side of the slant frame 26. A cone block 28 is rotatably connected to the guide shaft 32. A slide rod 27 is slidably connected to the slant frame 26. A folding plate 5 is connected to one end of the slide rod 27. A rotating rod 9 is rotatably connected to one end of the folding plate 5. A turntable 8 is connected to one end of the rotating rod 9. The rotating rod 9 is deflected and vertically connected to the turntable 8. The turntable 8 is connected to one side of the drive wheel 25.

[0034] Specifically, such as Figure 1 As shown, a connecting frame 3 is connected to the sorting bin 4, and the other end of the connecting frame 3 is connected to the processing bin 1. The connection between the sorting bin 4 and the processing bin 1 is strengthened by setting the connecting frame 3.

[0035] Specifically, such as Figure 5 As shown, a torsion spring 33 is connected to one side of the cone block 28, and the other end of the torsion spring 33 is connected to the inclined frame 26. The torsion spring 33 is sleeved on the guide shaft 32, and the tip of the cone block 28 abuts against the inclined frame 26. By setting the torsion spring 33, one end of the cone block 28 is made to abut against the inclined frame 26, so as to avoid the inability to reset the cone block 28 in time by gravity alone, which would prevent the slide bar 27 from moving along the prescribed route.

[0036] In summary, the jujube kernel cleaning and dehulling equipment based on a peeling structure provided in this embodiment allows multiple kernels to be placed at the end of the sorting bin 4 with a larger inclination during dehulling. This allows the kernels to slide along the inclined surface of the sorting bin 4 to the bottom. The motor 6 is then started, driving the turntable 8 to rotate. The rotating rod 9 eccentrically connected to the turntable 8 moves the folding plate 5 on the sorting bin 4. The lower end of the folding plate 5 sweeps across the sorting bin 4, causing the kernels on the sorting bin 4 to move with the folding plate 5. The kernels then pass through the feeding trough 31. Because the opening sizes of the two ends of the feeding trough 31 are different, with a smaller opening near the cone 28 and a larger opening near the turntable 8, smaller kernels fall from the end near the cone 28 into the processing bin 1. Larger kernels fall from the end away from the cone 28 into the processing bin 1, achieving sorting and processing of kernels of different sizes and improving processing accuracy.

[0037] When the folding plate 5 initially moves, the sliding rod 27 connected to one side of the folding plate 5 will slide on the inclined frame 26. When the sliding rod 27 contacts the cone block 28, the cone block 28 will deflect upward. When the folding plate 5 returns to its original position, the folding plate 5 begins to move towards the cone block 28. Since the tip of the cone block 28 is in contact with the inclined frame 26 and the cross-section of the sliding rod 27 is circular, the sliding rod 27 will slide from the upper surface of the cone block 28. At this time, one end of the folding plate 5 is lifted. When the folding plate 5 leaves the cone block 28, one end of the folding plate 5 will fall back onto the sorting bin 4 under the action of gravity. When the folding plate 5 continues to move, it can drive the next batch of jujube kernels to be sorted and moved.

[0038] The cone block 28 has a triangular tip at one end and a semi-circular teardrop-shaped structure at the other end. The torsion spring 33 structure is provided so that the cone block 28 can keep its tip abutting against the inclined frame 26 when it is not subjected to external force.

[0039] Multiple feeding troughs 31 are provided. Jujube pits falling from the sorting bin 4 can automatically enter different chambers of the processing bin 1. The chambers are divided by partitions 34. This division of jujube pits of different sizes can achieve refined shelling operations and improve shelling quality.

[0040] When the motor 6 is running, it can synchronously drive the drive wheel 25 to rotate, which in turn drives the driven wheel 13 to rotate with the belt 14. Since the bevel gear 11 and bevel gear 22 mesh with each other, when the drive wheel 25 rotates, it can synchronously drive the bevel gear 11 to rotate. The bevel gear 11 pushes the rotating plate 20 to rotate around the intermediate shaft 22 through the traction bar 15. The rotation of the rotating plate 20 achieved by the drive wheel 25 is a reciprocating rotation, that is, the rotating plate 20 will alternately rotate forward and backward. Through the pull bar 19 at both ends of the rotating plate 20, the synchronous frame 17 can be pulled to move alternately between near the processing chamber 1 and away from the processing chamber 1. When the synchronous frame 17 is close to the processing chamber 1, the extrusion plate 29 connected by the screw 23 can extrude the jujube pits in the processing chamber 1 to remove their shells.

[0041] Since the timing frame 17 and the screw 23 are connected by the nut 24, different clamping distances can be achieved by adjusting the position of the screw 23 connected to the timing frame 17, so that different shelling operations can be performed for date pits of different sizes.

[0042] By setting the horizontal plate 16, when the date pits fall from the sorting bin 4 into the processing bin 1, they can be prevented from entering between the extrusion plate 29 and the processing bin 1, and instead fall directly onto the horizontal plate 16. When the extrusion plates 29 move away from each other, the date pits on the horizontal plate 16 can fall into the shelling area under the action of the side wall of the processing bin 1.

[0043] Traditionally, the shelling of jujube kernels involves manually tapping the kernel to break the shell, allowing the kernel to separate from the shell. While simple, this method is time-consuming and labor-intensive. Furthermore, the tapping force varies depending on the kernel size, resulting in poor precision and potential damage to the kernel. This new equipment avoids the problem of contaminating the kernel during manual shelling, achieving a clean shelling process. Moreover, by processing kernels of different sizes accordingly, the equipment improves shelling efficiency and prevents damage to the kernel.

[0044] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
