[0002] The seeds of the Chinese jujube have important medicinal and economic value. In order to extract the seeds of the Chinese jujube, the shell of the Chinese jujube needs to be crushed.

[0003] Traditionally, the shell crushing and screening of jujube kernels is done by manually placing the jujube kernels one by one in a mortar, and then using a pestle to pound the kernels to break the shells to obtain the jujube kernels. This is not only inefficient, but also the kernels are likely to be broken due to poor control of the force, thus affecting the integrity of the kernels. In the later stage, the jujube kernels need to be manually screened according to their quality and fullness, which takes a lot of time and effort. Utility Model Content

Since the crushing roller is a frustum structure and is relatively inclined inwardly and the depth of the material guide groove gradually becomes shallower along the direction approaching the free end of the crushing roller, the jujube kernel is subjected to increasing pressure from the crushing rollers on both sides, thereby causing the jujube kernel to be squeezed and crushed.

[0009] Furthermore, a first vibration motor is connected to the bottom end of the vibration separation plate, and the vibration separation plate is driven by the first vibration motor to vibrate, so that the shell and kernel of the sour jujube kernel with shell are separated under continuous vibration.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Combined with Figure 1 , Figure 2 , Figure 4 and Figure 3 , a device for crushing and screening jujube kernel shells, comprising a crushing box 1, a storage box 2 is connected to one side of the top of the crushing box 1, a plurality of feeding hoppers 3 are connected to the bottom of the storage box 2, the bottom of the feeding hoppers 3 are respectively connected to guide pipes 4 extending into the crushing box 1, the crushing box 1 is respectively connected to crushing components at the bottom of the guide pipe 4, the crushing component comprises a crushing roller 7 rotatably connected to both sides below the guide pipe 4, a first gear 8 is connected to the crushing roller 7 on one side, and a second gear 9 is connected to the crushing roller 7 on the other side, the first gear 8 and the second gear 9 are meshed, the crushing roller 7 is a truncated cone structure and is relatively inclined inwardly, the crushing roller 7 is relatively connected to a spiral guide groove 10, and the depth of the guide groove 10 gradually becomes shallower along the direction of the crushing roller 7 close to the free end;

[0025] Through the coordinated arrangement of the crushing box 1, the storage box 2, the feeding hopper 3, the guide pipe 4, the crushing assembly, the vibrating separation plate 5, the shelling assembly and the screening assembly in the above structure, it is convenient to temporarily store the jujube pits through the storage box 2. The stored jujube pits can be introduced into the crushing box 1 one by one through the coordinated arrangement of the feeding hopper 3 and the guide pipe 4 for crushing. By driving the crushing roller 7 to rotate, the crushing roller 7 is meshed with the first gear 8 and the second gear 9 so that the two crushing rollers 7 rotate in opposite directions at the same time, thereby facilitating the transfer of the jujube pits introduced into the guide trough 10 from the guide pipe 4. Since the crushing roller 7 is a truncated cone structure and is relatively inclined inwardly and the depth of the guide trough 10 gradually becomes shallower along the direction close to the free end, the jujube pits are subjected to increasing pressure from the crushing rollers 7 on both sides, thereby causing the jujube pits to be squeezed and crushed.

[0026] Combined with Figure 2 and Figure 3 The crushing box 1 is connected with a vibration separation plate 5 below the crushing assembly, and a first vibration motor 11 is connected to the bottom of the vibration separation plate 5. A gap 6 is provided between the other end of the vibration separation plate 5 and the crushing box 1. The crushing box 1 is connected with a shelling assembly at the bottom of the vibration separation plate 5. The shelling assembly includes a separation box 12 connected to one side of the crushing box 1. A negative pressure fan 13 is rotatably connected to the top of the separation box 12. A collection pipe 14 is connected to one side of the separation box 12. The other end of the collection pipe 14 passes through the crushing box 1 and extends to the free end of the vibration separation plate 5. The separation box 12 is connected with a filter 15 between the collection pipe 14 and the negative pressure fan 13.

[0027] The crushed jujube kernels can be further separated from the jujube shells and kernels by the vibration separation plate 5. The first vibration motor 11 in the above structure drives the vibration separation plate 5 to vibrate, so that the shells and kernels of the jujube kernels with shells are separated under continuous vibration. Then the jujube shells are removed cleanly by the shelling component, and the negative pressure fan 13 is started. The negative pressure fan 13 rotates to generate negative pressure to suck the lighter jujube shells on the vibration separation plate 5 through the collection pipe 14 and introduce them into the separation box 12. The setting of the filter 15 prevents the shells from being introduced into the range of the negative pressure fan 13 and affecting its work.

[0028] Combined with Figure 3 A screening assembly is connected to the bottom of the crushing box 1, and the screening assembly includes a screening plate 16 connected to the bottom of the crushing box 1, and the screening plate 16 is inclined downward in a direction away from the vibration separation plate 5. A second vibration motor 17 is connected to the bottom of the screening plate 16, and a plurality of screening holes 18 are connected to the screening plate 16. The diameter of the screening holes 18 gradually increases along the inclination direction of the screening plate 16. The crushing box 1 is provided with a plurality of collecting boxes 19 below the screening plate 16, and a baffle door 20 is hingedly provided on one side of the bottom of the crushing box 1.

[0029] The coordinated arrangement of the screening plate 16, the screening holes 18, the second vibration motor 17 and the collecting box 19 in the above structure facilitates the separation of the wild jujube kernels according to their sizes, thereby improving the separation effect.

[0030] The specific usage is as follows:

[0031] First, the dried sour jujube kernels are introduced into the storage box 2 for temporary storage, and the guide tube 4 cooperates with the sour jujube kernels, and the sour jujube kernels are introduced into the crushing box 1 one by one through the guide tube 4 and fall into the guide trough 10;

[0032] Then, the crushing roller 7 is driven. The first gear 8 and the second gear 9 are meshed to make the crushing rollers 7 on both sides rotate in opposite directions at the same time, so as to transfer the sour jujube kernel in the guide groove 10. Since the crushing roller 7 is a truncated cone structure and is relatively inclined inwardly, the depth of the guide groove 10 gradually becomes shallower along the direction close to the free end, so that the sour jujube kernel is subjected to greater and greater pressure from the crushing rollers 7 on both sides until the sour jujube kernel is squeezed and crushed. The structure of the crushed sour jujube kernel is no longer complete, so that the pressure it receives is reduced, and it can be guided from the other end of the crushing roller 7 to the vibration separation plate 5 through the guide groove 10, so as to ensure the integrity of the sour jujube kernel; the vibration of the vibration separation plate 5 drives the shell and kernel to further move relative to each other, thereby promoting the separation of the shell and kernel;

[0033] Next, by starting the negative pressure fan 13, negative pressure is generated in the separation box 12, thereby driving the collection pipe 14 to suck the light-density sour jujube shells into the separation box 12, and the filter 15 is set to prevent the shells from entering the range of the negative pressure fan 13 and affecting its work;

[0034] Finally, the remaining Chinese jujube kernels are screened by the screening assembly. By starting the second vibration motor 17, the second vibration motor 17 causes the screening plate 16 to vibrate continuously, thereby facilitating the screening of the Chinese jujube kernels and preventing the Chinese jujube kernels from clogging the screening holes 18. Since the diameter of the screening holes 18 gradually increases along the inclination direction of the screening plate 16, it is convenient to separate the Chinese jujube kernels of different diameters. Finally, they are collected by the collecting box 19. The setting of the baffle door 20 facilitates the taking and placing of the collecting box 19.
