[0002] Jujube kernels can be used as raw materials to further process jujube seeds. In traditional Chinese medicine, jujube seeds are a classic medicine for calming the mind and aiding sleep. The Compendium of Materia Medica records that they "nourish the middle and benefit the liver, strengthen tendons and bones, and assist yin qi." With the increasing demand for sleep health among modern people, the market demand for jujube seeds continues to rise. In industrial processing, jujube kernels can be polished and carved into bracelets, ornaments, and other cultural and artistic items. Their hard texture and unique patterns are highly favored by the market. Jujube kernel activated carbon, produced after high-temperature pyrolysis, is widely used in food purification, wastewater treatment, and other fields due to its excellent adsorption properties.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model, through the design of a removal mechanism and a water spraying mechanism, utilizes several interlocking removal brushes to repeatedly sweep the outer wall of the jujube pit. This friction, combined with the friction between several jujube pits, removes the residual fruit pulp from the pit. At the same time, the water spraying mechanism sprays water onto the jujube pit to moisten it, thereby softening the jujube pulp and reducing its hardness, making it easier for the removal brushes to remove. This improves the removal efficiency of the jujube pulp. Compared with existing technologies, it eliminates the need for manual rubbing, significantly improving the removal efficiency of the jujube pulp.

[0019] 2. This utility model integrates the cleaning of jujube pits, the removal of jujube pulp, and the screening of jujube pulp and pits through the design of a box body, a rejection mechanism, a screening mechanism, and a water spraying mechanism. Compared with the prior art, it eliminates the need to perform each step individually. Multiple mechanisms can work together to achieve the cleaning of jujube pits, the removal of jujube pulp, and the screening of jujube pulp and pits, thereby improving the overall processing efficiency of jujube pits.

[0020] 3. This utility model, by symmetrically designing two bellows protective covers directly on the outer wall of one adjacent end of the two half-shells, can prevent the water sprayed from the nozzles after the two half-shells are opened from washing the jujube flesh and jujube pits to the outside of the two half-shells, thus avoiding waste.

[0021] 4. This utility model, through the design of an outlet and a discharge outlet, facilitates the quick removal of the sifted jujube pulp and jujube pits, improving the feeding efficiency of both and avoiding spoilage caused by prolonged storage inside the box.

[0022] 5. The water spraying mechanism designed in this utility model can not only rinse the jujube pits for cleaning, but also, after the jujube pulp is removed and falls into the filter frame, the swing arm drives several nozzles to swing back and forth left and right to impact the jujube pulp located on the inner wall of the filter frame. Since there are several filter holes smaller than the jujube pits on the outer wall of the filter frame, the jujube pulp can be flushed from the filter holes to the top of the feeding chute. The same mechanism can perform multiple functions, thereby improving the practicality of this device. Attached Figure Description

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0035] Reference Figures 1 to 8 As shown, the jujube pit cleaning and screening device includes a housing 1;

[0036] It also includes rejection mechanisms, screening mechanisms, and water spraying mechanisms;

[0037] The rejection mechanism is located inside the housing 1. The rejection mechanism includes two half-shells 2, two motors 3, several rotating rollers 4, and several transmission components. The two half-shells 2 are slidably mounted on the housing 1. Several rotating rollers are rotatably mounted inside the two half-shells 2 via several rotating shafts 5. Several rejection brushes 6 are evenly spaced on the outer wall of each rotating roller. The rejection brushes 6 on the rotating rollers are staggered. Each motor 3 is fixedly mounted on one half-shell 2, and the output end of each motor 3 is fixedly connected to the end of one of the rotating shafts 5. Each transmission component is located between every two rotating shafts 5.

[0038] The screening mechanism is located inside the housing 1. The screening mechanism includes a feeding chute 7 and a filter assembly. The filter assembly is located between the bottoms of the two half-shells 2. The feeding chute 7 is fixedly installed on the inner wall of the housing 1.

[0039] The water spraying mechanism is located on the top of the housing 1. The water spraying mechanism includes a receiving pipe 8, a swing assembly, and several nozzles 9. An L-shaped block is fixedly installed on the top of the housing 1. The receiving pipe 8 is rotatably mounted on the L-shaped block via a rotating rod 10. The swing assembly is located between the housing 1 and the rotating rod 10. Several nozzles 9 are evenly spaced on the outer wall of the receiving pipe 8.

[0040] Reference Figures 1 to 8 As shown, each transmission component includes a synchronous belt 11 and two synchronous pulleys 12. Each synchronous pulley 12 is fixedly mounted on the outer wall of a rotating shaft 5. The synchronous belt 11 is sleeved between the two synchronous pulleys 12. This device is equipped with a controller, and all electrical devices on the device are electrically connected to the controller. When cleaning and screening jujube pits, the jujube pits are first placed between several rotating rollers inside the box 1. Then, the controller starts two motors 3. Since several rotating rollers are rotatably connected to the inside of two half-shells 2 through several rotating shafts 5, several rejection brushes 6 are fixedly designed on the outer wall of each rotating roller. The rejection brushes 6 on the several rotating rollers are interlaced. The output end of each motor 3 is fixedly connected to the end of one of the rotating shafts 5. Each synchronous pulley 12 Each component is fixedly connected to a rotating shaft 5, and two synchronous pulleys 12 are connected by a synchronous belt 11. As long as the rotation direction of the two motors 3 is the same, the jujube pits can be made to bounce back and forth between several rotating rollers 4. Then, several interlocking removal brushes 6 are used to clean the outer wall of the jujube pits. This friction, combined with the friction between several jujube pits, removes the residual fruit pulp from the jujube pits. At the same time, the water pump 31 needs to be started by the controller, so that the water source is connected through the input end of the water pump 31. Then, the water is delivered to the inside of several nozzles 9 through its input end, delivery pipe 30 and receiving pipe 8 to wet the jujube pits, thereby softening the jujube pulp and reducing its hardness, making it easier for the removal brushes 6 to remove it, thus improving the removal effect of the jujube pulp.

[0041] Reference Figures 1 to 8 As shown, two symmetrical clearance notches are arranged on the outer walls of both ends of the housing 1. A U-shaped plate 13 is fixedly installed on the outer wall of each clearance notch. Two sliding rods 14 are slidably installed on the outer wall of each U-shaped plate 13. Each half-shell 2 is fixedly connected to the end of the two sliding rods 14 away from the U-shaped plate 13. A first insertion rod 15 is fixedly installed on the outer wall of each half-shell 2. An L-shaped plate is fixedly installed on the end of each first insertion rod 15 away from the half-shell 2. Each first insertion rod 15 is inserted into a U-shaped plate 13. A bidirectional electric push rod 16 is fixedly installed on the top of the outer side of the housing 1. The two output ends of the bidirectional electric push rod 16 are respectively connected to the two L-shaped plates away from the first... One end of a rod 15 is fixedly connected. The outer wall of the box 1 is symmetrically provided with clearance grooves for two motors 3 to slide horizontally. After all the residual jujube flesh on the outer wall of the jujube is removed, the bidirectional electric push rod 16 is activated by the controller, so that both of its output ends extend. Since each output end is fixedly connected to a first rod 15 through an L-shaped plate, and each first rod 15 is fixedly connected to a half-shell 2, and each half-shell 2 is fixedly connected to a U-shaped plate 13 through two sliding rods 14, the two half-shells 2 are moved away from each other, which further drives several rotating rollers 4 to move away from each other, that is, several rotating rollers 4 are separated into two halves.

[0042] Reference Figures 1 to 8 As shown, each half-shell 2 has two sliders 17 fixedly installed on the outer wall of the end away from the synchronous wheel 12, and four slide rails 18 fixedly installed on the inner wall of the housing 1. Each slider 17 is slidably connected to one slide rail 18. One half-shell 2 has a receiving groove at the end away from the U-shaped plate 13. An accordion protective cover 19 is fixedly installed inside the receiving groove. The end of the accordion protective cover 19 away from the receiving groove is fixedly connected to the end of the other half-shell 2 away from the U-shaped plate 13. When the two half-shells 2 move away from each other, the two accordion protective covers 19 change from a retracted state to an unfolded state, blocking the gap between the two half-shells 2 and preventing the jujube pits and the removed jujube pulp from splashing to the outside of the two half-shells 2 under the impact of water, thus avoiding waste. The four sliders 17, together with the four slide rails 18, improve the sliding stability of the two half-shells 2.

[0043] Reference Figures 1 to 8 As shown, the filter assembly includes a filter frame 20, two slide bars 21, and two guide rails 22. The two guide rails 22 are fixedly mounted on the inner wall of the housing 1. Each slide bar 21 is slidably mounted on one guide rail 22. The filter frame 20 is fixedly mounted between the two slide bars 21. The top of the filter frame 20 is in contact with the bottom of the two half-shells 2. The outer wall of the filter frame 20 has several filter holes 23 smaller than the jujube pit. When the two half-shells 2 drive several rotating rollers 4 to separate into two halves, under the impact of the falling water sprayed from several nozzles 9, the jujube pit and the removed jujube flesh fall together from the bottom of the two half-shells 2 into the interior of the filter frame 20.

[0044] Reference Figures 1 to 8 As shown, the swing assembly includes a one-way electric push rod 24, a second insert rod 25, and a swing rod 26. The swing rod 26 is fixedly mounted on the end of the rotating rod 10 away from the receiving tube 8. A traction groove 27 is provided on the outer wall of the swing rod 26. The one-way electric push rod 24 is hinged to the outer wall of the housing 1. The second insert rod 25 is fixedly mounted on its output end and is inserted into the traction groove 27. A sleeve 28 is fixedly mounted on the end of the receiving tube 8 away from the rotating rod 10. A sealed bearing 29 is fixedly mounted inside the sleeve 28. A conveying pipe 30 is fixedly mounted on the inner ring of the sealed bearing 29. A water pump 31 is fixedly mounted on the top inner side of the housing 1. The end of the conveying pipe 30 away from the receiving tube 8 is fixedly connected to the output end of the water pump 31. A round hole for the conveying pipe 30 to rotate is provided on the end of the receiving tube 8 near the water pump 31. When the jujube pits and the removed jujube pulp fall together from the bottom of the two half-shells 2 into the interior of the filter frame 20, the controller starts the one-way electric push rod 24. The electric push rod 24 extends or retracts its output end. Since its output end is fixedly connected to the second insert rod 25, and the swing rod 26 and the receiving tube 8 are fixedly connected to the two ends of the rotating rod 10 respectively, the resistance force generated by the second insert rod 25 and the inside of the traction groove 27 when rotating is transformed into the rotational force of the rotating rod 10, which drives the receiving tube 8 and several nozzles 9 on its outer wall to swing back and forth, thereby impacting the jujube pulp and jujube pits that fall into the filter frame 20. Since the outer wall of the filter frame 20 is designed with several filter holes 23 smaller than the jujube pits, the softened jujube pulp is pushed from the filter holes 23 to the top of the feeding slide 7. The remaining jujube pits cannot pass through the filter holes 23 and are automatically temporarily stored inside the filter frame 20. After the screening work is completed, the filter frame 20 can be pulled out and taken out. The sealed bearing 29 is designed to prevent the receiving tube 8 from colliding with the conveying tube 30 when rotating, so as to ensure the conveying effect of the conveying tube 30.

[0045] Reference Figures 1 to 8 As shown, the outer wall of the box 1 is provided with an outlet 32 ​​for removing the filter frame 20. When the jujube pulp inside the filter frame 20 is flushed to the top of the feeding chute 7 by water through the filter hole 23, only the jujube pits are left inside the filter frame 20. The width of the outlet 32 ​​is designed to be greater than the width of the filter frame 20, so that the cleaning personnel can easily reach into the box 1 with both hands to pull out the filter frame 20 and remove the jujube pits after screening.

[0046] Reference Figures 1 to 8 As shown, a discharge port 33 is provided on the outer wall of the box 1. The residual jujube pulp that falls to the top of the feeding chute 7 after screening can be discharged to the outside of the box 1 through the discharge port 33, so as to separate it from the jujube pit.
