Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, specifically a crushing device for fermenting jujubes. Background Technology

[0002] Sour jujube, also known as wild jujube, is smaller and rounder than regular jujubes. Its skin is purplish-red, smooth, and wrinkle-free. It has a sour taste and can be eaten raw or used medicinally. Sour jujube is a perennial shrub that thrives in sunlight, is drought-tolerant, cold-hardy, but intolerant of waterlogging. It has strong vitality and requires no artificial cultivation. In particular, it has a strong resistance to pests and diseases, eliminating the need for pesticide spraying, thus falling into the category of green food. Sour jujube has high nutritional value.

[0003] When brewing jujube wine, the jujubes need to be fermented. Before fermentation, the jujubes need to be crushed to separate the flesh from the pit. Currently, a crushing machine is commonly used to directly squeeze and crush the jujubes.

[0004] The jujube flesh is densely attached to the surface of the jujube pit. When using the existing crushing method, it is impossible to remove all the jujube flesh from the surface of the pit. Some jujube flesh remains on the surface of the pit, resulting in low utilization of the jujube flesh. Furthermore, after crushing sour jujubes, it is not easy to control the separation of jujube flesh from the pit, resulting in low overall crushing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a crushing device for jujube fermentation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A crushing device for jujube fermentation includes a base, a crushing cylinder fixedly installed above the base, a screen plate fixedly installed inside the crushing cylinder with uniformly distributed screen holes on its surface, and a funnel-shaped bottom end of the crushing cylinder. A separation cylinder is fixedly installed above the base, positioned directly below the crushing cylinder, and a guide pipe is provided at its bottom end. A crushing mechanism is installed inside the crushing cylinder, comprising crushing components, a positioning component, and a driving component. The crushing components include a lower crushing rod and an upper crushing rod. The positioning component is located on the surface of the screen plate and connected to the lower and upper crushing rods, and is used to position the lower and upper crushing rods on the upper surface of the screen plate.

The driving component controls the lower and upper crushing rods to rotate in opposite directions inside the crushing cylinder by cooperating with the positioning component. The separation cylinder is equipped with a collection mechanism, which includes a bearing plate, a lifting component, and a tilting component. The surface of the bearing plate is provided with a water-permeable mesh. The lifting component is located inside the separation cylinder and connected to the bearing plate. The lifting component is used to control the bearing plate to move vertically inside the separation cylinder. The tilting component is connected to the lifting component. When the bearing plate moves vertically, the tilting component is used to control the bearing plate to switch between a horizontal and a vertical state.

[0008] As a further embodiment of the present invention: the driving assembly includes two sets of horizontal plates fixedly installed on the inner side wall of the crushing cylinder, a vertical rod rotatably installed between the two sets of horizontal plates, a positioning toothed disc fixedly installed on the vertical rod and the surface of the column respectively, the two sets of positioning toothed discs meshing with each other, a synchronous disc fixedly installed on the vertical rod and the surface of the positioning ring respectively, and the two sets of synchronous discs are connected together by a synchronous belt.

[0009] As a further aspect of the present invention: a protective cover is fixedly installed on the inner wall of the crushing cylinder, and the protective cover is sleeved on the outside of the horizontal plate, the positioning toothed plate and the synchronization plate.

[0010] As a further embodiment of the present invention: the lifting assembly includes two sets of oppositely distributed fixed frames fixedly installed at the top of the separating cylinder, a threaded rod rotatably installed between the fixed frame and the bottom wall of the separating cylinder, a positioning block slidably installed on the inner side wall of the separating cylinder in the vertical direction, the threaded rod being threadedly connected to the positioning block, a bearing rod rotatably installed on the opposite side walls of the two sets of positioning blocks, a bearing plate fixedly installed on the surface of the bearing rod, the bottom end of the threaded rod extending to the bottom of the separating cylinder and fixedly installed with a synchronous gear plate, the two sets of synchronous gear plates being connected to a synchronous toothed belt, a second motor fixedly installed on the bottom wall of the separating cylinder, and the output shaft of the second motor being connected to a set of threaded rods.

[0011] As a further aspect of the present invention: the flipping assembly includes a guide toothed disc fixedly mounted on the surface of a support rod, the guide toothed disc being located between the positioning block and the support plate, a support rod fixedly mounted on the inner wall of the separation cylinder, a first guide rack fixedly mounted on the end of the support rod away from the inner wall of the separation cylinder, the guide toothed disc meshing with the first guide rack, and a fixing member connected to the positioning block being provided on the surface of the guide toothed disc.

[0012] As a further embodiment of the present invention: the fixing member includes four sets of first magnetic plates that are fixedly installed on the side wall of the guide tooth disk and are distributed in a ring at equal intervals, and the positioning block has four sets of second magnetic plates that cooperate with the first magnetic plates.

[0013] As a further embodiment of the present invention: a guide plate is slidably mounted on the surface of the bearing plate, an L-shaped rod is fixedly mounted on the top of the separating cylinder, and a second guide rack is fixedly mounted on the end of the L-shaped rod away from the separating cylinder, the second guide rack meshing with the guide toothed disc.

[0014] As a further aspect of the present invention: the surface of the bearing plate is provided with a limiting member connected to the guide plate, the limiting member including a limiting groove opened in the side wall of the bearing plate, a limiting block being slidably installed in the limiting groove, the limiting block extending to the outside of the limiting groove and being fixedly connected to the guide plate.

[0015] As a further embodiment of the present invention: the guide toothed disc is provided in two sets, and the two sets of guide toothed discs are respectively located on both sides of the bearing disc.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting the positioning component and the driving component to cooperate with each other, multiple sets of lower crushing rods and multiple sets of upper crushing rods can be controlled to rotate in opposite directions inside the crushing cylinder. During the rotation process, the multiple sets of lower crushing rods and multiple sets of upper crushing rods can not only crush the jujubes by squeezing, but also knock away the jujube pulp attached to the surface of the jujube pit, effectively improving the utilization rate of the jujube pulp. This solves the problem that the jujube pulp is densely attached to the surface of the jujube pit, and some jujube pulp remains on the surface of the jujube pit, resulting in a low utilization rate of the jujube pulp.

[0017] By setting up lifting and tilting components to work together, the height and angle of the carrying plate can be easily adjusted, thereby controlling the carrying plate to collect and process the jujube pulp floating on the water surface. This solves the problem that it is currently impossible to easily control the separation of jujube pulp from the pit, resulting in low overall crushing efficiency. Attached Figure Description

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3The diagram shows a structural diagram of a crushing device for jujube fermentation according to an embodiment of the present invention. It includes a base 1, a crushing cylinder 2 fixedly mounted on top of the base 1, a screen plate 21 fixedly mounted inside the crushing cylinder 2, the surface of the screen plate 21 having evenly distributed screen holes, and a funnel-shaped bottom end of the crushing cylinder 2. A separation cylinder 3 is fixedly mounted above the base 1, positioned directly below the crushing cylinder 2, and a guide pipe 31 is provided at the bottom end of the separation cylinder 3. A crushing mechanism 4 is provided inside the crushing cylinder 2, the crushing mechanism 4 including a crushing component 41, a positioning component 42, and a driving component 43. The crushing component 41 includes a lower crushing rod 411 and an upper crushing rod 412. The positioning component 42 is located on the surface of the screen plate 21 and connected to the lower crushing rod 411 and the upper crushing rod 412. The positioning component 42 is used to position the crushing component on the upper surface of the screen plate 21. The lower crushing rod 411 and the upper crushing rod 412 provide support. The driving component 43 is located in the inner cavity of the crushing cylinder 2 and is connected to the positioning component 42. The driving component 43 controls the lower crushing rod 411 and the upper crushing rod 412 to rotate in opposite directions in the inner cavity of the crushing cylinder 2 by cooperating with the positioning component 42. The inner cavity of the separation cylinder 3 is provided with a collection mechanism 5. The collection mechanism 5 includes a bearing plate 51, a lifting component 52 and a tilting component 53. The surface of the bearing plate 51 is provided with a water-permeable mesh. The lifting component 52 is located in the inner cavity of the separation cylinder 3 and is connected to the bearing plate 51. The lifting component 52 is used to control the movement of the bearing plate 51 in the vertical direction in the separation cylinder 3. The tilting component 53 is connected to the lifting component 52. When the bearing plate 51 moves in the vertical direction, the tilting component 53 is used to control the switching of the bearing plate 51 between the horizontal and vertical states.

[0031] When in use, inject an appropriate amount of water into the separation cylinder 3. When crushing jujubes, put an appropriate amount of jujubes into the crushing cylinder 2. The jujubes fall onto the surface of the screen plate 21. The positioning component 42 supports and positions the lower crushing rod 411 and the upper crushing rod 412 on the surface of the screen plate 21. The lower crushing rod 411 and the upper crushing rod 412 are distributed at intervals. The drive assembly 43 and the positioning assembly 42 cooperate with each other to control multiple sets of lower crushing rods 411 and multiple sets of upper crushing rods 412 to rotate in opposite directions inside the crushing cylinder 2. When the lower crushing rods 411 and the upper crushing rods 412 rotate, they can push the jujubes between two adjacent sets of lower crushing rods 411 and upper crushing rods 412. The relative movement of the lower crushing rods 411 and the upper crushing rods 412 can conveniently crush the jujubes. After the jujubes are initially crushed, the jujube flesh and pits that meet the size requirements fall through the sieve holes into the separation cylinder 3. The larger jujube flesh and pits remain on the surface of the sieve plate 21. During the relative rotation of the lower crushing rods 411 and the upper crushing rods 412, they can knock on the jujube flesh and pits. The lower crushing rods 411 and the upper crushing rods 412 can further crush the jujube flesh and conveniently remove the jujube flesh attached to the surface of the pits.

[0032] The lifting component 52 and the tilting component 53 work together to position the carrying plate 51 inside the separation cylinder 3. The carrying plate 51 is in a vertical position inside the separation cylinder 3. After the date flesh and date pits fall into the separation cylinder 3, the date pits sink to the bottom of the water under the action of gravity, while the date flesh has a lower density and floats on the water surface. When it is necessary to collect the date flesh, the lifting component 52 controls the carrying plate 51 to move vertically upward. During the upward movement of the carrying plate 51, the tilting component 53 controls the carrying plate 51 to rotate to a horizontal position. When the horizontal carrying plate 51 moves upward, it can collect the date flesh floating on the water surface. When the carrying plate 51 moves above the separation cylinder 3, the staff can easily remove the date flesh from the surface of the carrying plate 51. After the date flesh is removed, the lifting component 52 controls the carrier plate 51 to move vertically downward into the inner cavity of the separation cylinder 3. When the carrier plate 51 moves downward, the flipping component 53 controls the carrier plate 51 to rotate from a horizontal state to a vertical state. In subsequent processing, this can effectively prevent the carrier plate 51 from interfering with the sinking process of the date pit in the water.

[0033] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, in a preferred embodiment of the present invention, the positioning component 42 includes a column 521 rotatably mounted on the surface of the screen plate 21, a bottom positioning plate 522 fixedly mounted on the surface of the column 521, multiple sets of lower crushing rods 411 fixedly mounted at equal intervals on the surface of the bottom positioning plate 522, a positioning ring 424 rotatably mounted on the surface of the column 521, a top positioning plate 425 fixedly mounted on the surface of the positioning ring 424, multiple sets of upper crushing rods 412 fixedly mounted at equal intervals on the bottom wall of the top positioning plate 425, the multiple sets of lower crushing rods 411 and the multiple sets of upper crushing rods 412 are distributed at intervals along the diameter direction of the screen plate 21, and a first motor 423 is fixedly mounted on the bottom wall of the screen plate 21, the output shaft of the first motor 423 being connected to the column 521.

[0034] In operation, the column 521 supports the bottom positioning plate 522 on the surface of the screen plate 21. The bottom positioning plate 522 supports and positions the lower crushing rods 411. The column 521 supports the positioning ring 525, the positioning ring 424 supports the top positioning plate 425, and the top positioning plate 425 supports and positions the upper crushing rods 412. When crushing jujubes, the first motor 423 drives the column 521 to rotate. The column 521 and the bottom positioning plate 522 cooperate to drive multiple sets of lower crushing rods 411 to rotate synchronously. When the column 521 rotates, the drive assembly 43 controls the positioning ring 525 to rotate outside the column 521, and further controls the positioning ring 525 to rotate in the opposite direction to the column 521. The positioning ring 525 drives multiple sets of upper crushing rods 412 to rotate synchronously, and at this time, the multiple sets of upper crushing rods 412 rotate in the opposite direction to the multiple sets of lower crushing rods 411.

[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment of the present invention, the drive assembly 43 includes two sets of horizontal plates 431 fixedly installed on the inner side wall of the crushing cylinder 2, and a vertical rod 432 rotatably installed between the two sets of horizontal plates 431. Positioning gear discs 433 are fixedly installed on the surfaces of the vertical rod 432 and the column 421, and the two sets of positioning gear discs 433 are meshed with each other. Synchronous discs 434 are fixedly installed on the surfaces of the vertical rod 432 and the positioning ring 424, and the two sets of synchronous discs 434 are connected together by a synchronous belt 435.

[0036] Two sets of horizontal plates 431 support and position the vertical rod 432. When the column 421 rotates, it drives the positioning gear 433 to rotate synchronously. The two sets of positioning gears 433 mesh with each other, which can drive the vertical rod 432 to rotate between the two sets of horizontal plates 431. The vertical rod 432 rotates in the opposite direction to the column 421. When the vertical rod 432 rotates, it drives the synchronous disc 434 to rotate synchronously. The two sets of synchronous discs 434 cooperate with the synchronous belt 435 to drive the positioning ring 424 to rotate on the surface of the column 421. The positioning ring 424 rotates in the opposite direction to the column 421.

[0037] like Figure 2 , Figure 5 As shown, in a preferred embodiment of the present invention, a protective cover 10 is fixedly installed on the inner wall of the crushing cylinder 2, and the protective cover 10 is sleeved on the outside of the horizontal plate 431, the positioning toothed plate 433 and the synchronous plate 434.

[0038] The protective cover 10 can enclose and protect components such as the positioning toothed disc 433 and the synchronization disc 434. During the crushing process, it can effectively prevent the jujubes from interfering with the transmission process of the positioning toothed disc 433 and the synchronization disc 434.

[0039] like Figure 2 , Figure 6 , Figure 8 , Figure 9 As shown, in a preferred embodiment of the present invention, the lifting assembly 52 includes two sets of opposing fixed frames 521 fixedly installed at the top of the separating cylinder 3. A threaded rod 522 is rotatably installed between the fixed frame 521 and the bottom wall of the separating cylinder 3. A positioning block 523 is slidably installed on the inner side wall of the separating cylinder 3 in the vertical direction. The threaded rod 522 is threadedly connected to the positioning block 523. A bearing rod 524 is rotatably installed on the two opposing side walls of the two sets of positioning blocks 523. A bearing plate 51 is fixedly installed on the surface of the bearing rod 524. The bottom end of the threaded rod 522 extends to the bottom of the separating cylinder 3 and is fixedly installed with a synchronous gear plate 525. The two sets of synchronous gear plates 525 are connected to a synchronous gear belt 526. A second motor 527 is fixedly installed on the bottom wall of the separating cylinder 3. The output shaft of the second motor 527 is connected to a set of threaded rods 522.

[0040] The threaded rod 522 supports and positions the positioning block 523 within the separation cylinder 3. Two sets of positioning blocks 523 support and position the bearing rod 524, which in turn supports and positions the bearing plate 51. When it is necessary to collect the jujube pulp from the water surface, the second motor 527 drives one set of threaded rods 522 to rotate. The threaded rods 522 drive the synchronous gear discs 525 to rotate. The two sets of synchronous gear discs 525 cooperate with the synchronous belt 526, enabling the two sets of threaded rods 522 to rotate synchronously within the separation cylinder 3. The threaded rods 522 push the positioning block 523 to move vertically. The positioning block 523 cooperates with the bearing rod 524 to easily control the vertical movement of the bearing plate 51. During the upward movement of the bearing plate 51, when it reaches above the water surface, the jujube pulp floating on the surface automatically falls onto the surface of the bearing plate 51, allowing workers to easily remove it.

[0041] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, in a preferred embodiment of the present invention, the flipping assembly 53 includes a guide toothed disc 531 fixedly mounted on the surface of a support rod 524. The guide toothed disc 531 is located between the positioning block 523 and the support disc 51. A support rod 532 is fixedly mounted on the inner wall of the separation cylinder 3. A first guide rack 533 is fixedly mounted on one end of the support rod 532 away from the inner wall of the separation cylinder 3. The guide toothed disc 531 meshes with the first guide rack 533. A fixing member connected to the positioning block 523 is provided on the surface of the guide toothed disc 531.

[0042] When the bearing plate 51 is inside the separation cylinder 3, it is in a vertical position. The fixing component and the guide toothed plate 531 cooperate with each other to further improve the stability of the bearing plate 51. When it is necessary to collect the jujube pulp on the water surface, the positioning block 523 drives the bearing rod 524 to move vertically upward. When the bearing rod 524 moves upward, it drives the guide toothed plate 531 to move upward synchronously. While moving upward, the guide toothed plate 531 rolls along the surface of the first guide rack 533. The guide toothed plate 531 drives the bearing rod 524 and the bearing plate 51 to rotate synchronously. After the bearing rod 524 and the bearing plate 51 have rotated 90 degrees, the guide toothed plate 531 and the first guide rack 533 separate from each other. At this time, the bearing plate 51 remains in a horizontal position, and the fixing component controls the bearing plate 51 to remain stably horizontal.

[0043] After the jujube pulp on the surface of the bearing plate 51 is removed, the positioning block 523 drives the bearing rod 524 to move vertically downward. When the bearing rod 524 moves downward, it drives the guide toothed plate 531 to move downward synchronously. The guide toothed plate 531 rolls along the surface of the first guide rack 533. The guide toothed plate 531 drives the bearing rod 524 and the bearing plate 51 to rotate synchronously. After the bearing rod 524 and the bearing plate 51 rotate 90 degrees, the guide toothed plate 531 and the first guide rack 533 separate from each other. At this time, the bearing plate 51 is kept vertical again in the separation cylinder 3, and the fixing component controls the bearing plate 51 to remain stably vertical.

[0044] like Figure 6 、 and 7、 Figure 8 As shown, in a preferred embodiment of the present invention, the fixing member includes four sets of first magnetic plates 5341 that are fixedly installed on the side wall of the guide toothed disc 531 and are distributed in a ring at equal intervals, and four sets of second magnetic plates 5342 that cooperate with the first magnetic plates 5341 are fixedly installed on the side wall of the positioning block 523.

[0045] Initially, the first magnetic piece 5341 on the side wall of the guide gear disk 531 is connected to the second magnetic piece 5342 on the side wall of the positioning block 523 by magnetic attraction, forming a whole. The guide gear disk 531 controls the bearing rod 524 and the bearing disk 51 to be stably positioned between the two sets of positioning blocks 523. When the guide gear disk 531 rotates, it drives the first magnetic piece 5341 to rotate synchronously. At this time, the first magnetic piece 5341 and the second magnetic piece 5342 separate from each other. When the guide gear disk 531 rotates ninety degrees, it separates from the first guide rack 533. At this time, the first magnetic piece 5341 on the side wall of the guide gear disk 531 is connected to the second magnetic piece 5342 on the side wall of the positioning block 523 by magnetic attraction, forming a whole again.

[0046] like Figure 6 , Figure 7 , Figure 9 As shown, in a preferred embodiment of the present invention, a guide plate 6 is slidably mounted on the surface of the bearing plate 51, an L-shaped rod 7 is fixedly mounted on the top of the separating cylinder 3, and a second guide rack 8 is fixedly mounted on the end of the L-shaped rod 7 away from the separating cylinder 3, the second guide rack 8 meshing with the guide toothed disc 531.

[0047] When the carrier plate 51 moves above the separation cylinder 3 and continues to move upward, the guide plate 6 is pulled out from the bottom wall of the carrier plate 51. The guide tooth plate 531 rolls along the surface of the second guide toothed plate 8. The guide tooth plate 531 and the carrier rod 524 cooperate with each other to control the carrier plate 51 to rotate to an inclined state. The jujube pulp slides on the surface of the carrier plate 51. The jujube pulp passes through the guide plate 6 and can automatically fall to the outside of the separation cylinder 3.

[0048] like Figure 6 , Figure 7 , Figure 9 As shown, in a preferred embodiment of the present invention, the surface of the bearing plate 51 is provided with a limiting member 9 connected to the guide plate 6. The limiting member 9 includes a limiting groove 91 opened in the side wall of the bearing plate 51. A limiting block 92 is slidably installed in the limiting groove 91. The limiting block 92 extends to the outside of the limiting groove 91 and is fixedly connected to the guide plate 6.

[0049] The limiting block 92 and the limiting groove 91 cooperate with each other to support and position the guide plate 6 at the side wall of the bearing plate 51, and can further limit the sliding range of the guide plate 6.

[0050] like Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, two sets of guide gears 531 are provided, with the two sets of guide gears 531 located on both sides of the bearing plate 51. The two sets of guide gears 531 can effectively improve the stability of the bearing rod 524 during rotation.

[0051] The working principle of this invention is as follows: During use, an appropriate amount of water is injected into the separation cylinder 3. When crushing jujubes, an appropriate amount of jujubes is added into the crushing cylinder 2, and the jujubes fall onto the surface of the screen plate 21. The first motor 423 drives the column 521 to rotate. The column 521 and the bottom positioning plate 522 cooperate with each other to drive multiple sets of lower crushing rods 411 to rotate synchronously. When the column 421 rotates, it drives the positioning toothed disc 433 to rotate synchronously. The two sets of positioning toothed discs 433 mesh with each other and drive the vertical rod 432 to rotate between the two sets of horizontal plates 431. The rotation direction of the vertical rod 432 is opposite to that of the column 421. When the vertical rod 432 rotates, it drives the synchronous disc 434 to rotate synchronously. The two sets of synchronous discs 434 and the synchronous belt 435 cooperate with each other to drive the positioning ring 424 to rotate on the surface of the column 421. The positioning ring 525 rotates in the opposite direction to the column 521. The positioning ring 525 drives multiple sets of upper crushing rods 412 to rotate synchronously. At this time, the multiple sets of upper crushing rods 412 rotate in the opposite direction to the multiple sets of lower crushing rods 411. When the lower crushing rod 411 and the upper crushing rod 412 rotate, they can push the jujubes between the two adjacent sets of lower crushing rods 411 and upper crushing rods 412. The relative movement of the lower crushing rods 411 and the upper crushing rods 412 can conveniently crush the jujubes. After the jujubes are initially crushed, the jujube flesh and pits that meet the size requirements fall through the sieve holes into the separation cylinder 3. The larger jujube flesh and pits remain on the surface of the sieve plate 21. During the relative rotation of the lower crushing rods 411 and the upper crushing rods 412, they can knock on the jujube flesh and pits. The lower crushing rods 411 and the upper crushing rods 412 can further crush the jujube flesh and conveniently remove the jujube flesh attached to the surface of the pits.

[0052] The carrying plate 51 is vertical inside the separation cylinder 3. After the jujube pulp and pits fall into the separation cylinder 3, the pits sink to the bottom due to gravity, while the pulp, being less dense, floats on the surface. When it is necessary to collect the pulp, the second motor 527 drives a set of threaded rods 522 to rotate. The threaded rods 522 drive the synchronous gear discs 525 to rotate. The two sets of synchronous gear discs 525 and synchronous gear belts 526 work together to drive the two sets of threaded rods 522 to rotate synchronously inside the separation cylinder 3. The threaded rods 522 push the positioning block 523 to move vertically. The positioning block 523 and the bearing rod 524 cooperate to easily control the vertical movement of the bearing plate 51. When the bearing rod 524 moves upward, it drives the guide toothed disc 531 to move upward synchronously. While moving upward, the guide toothed disc 531 rolls along the surface of the first guide rack 533. The guide toothed disc 531 drives the bearing rod 524 and the bearing plate 51 to rotate synchronously. After the bearing rod 524 and the bearing plate 51 have rotated 90 degrees, the guide toothed disc 531 separates from the first guide rack 533, and the bearing plate 51 remains horizontal. When the horizontal bearing plate 51 moves upward, it can collect the jujube pulp floating on the water surface. When the bearing plate 51 moves above the separation cylinder 3, the staff can easily remove the jujube pulp from the surface of the bearing plate 51. After the jujube flesh is removed, the support plate 51 is moved vertically downwards into the inner cavity of the separation cylinder 3. When the support plate 51 moves downwards, the guide tooth plate 531 controls the support plate 51 to rotate from a horizontal state to a vertical state. In subsequent processing, this can effectively prevent the support plate 51 from interfering with the sinking process of the jujube pit in the water.

[0053] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
