[0005] In one embodiment of this utility model, the screening cylinder is driven to rotate intermittently by the screening motor. When the screening cylinder rotates, the bayberry fruit moves centrifugally and passes through the corresponding screening holes. When the screening cylinder stops rotating, the bayberry fruit gathers towards the center along the inverted conical structure of the screening plate.

[0006] In one embodiment of this utility model, at least two of the crushing rollers are arranged in parallel, and the spacing between adjacent crushing rollers is adjustable.

However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the technical solution of this utility model.

[0019] Example 1 Existing bayberry juicing equipment mostly employs a single crushing and filtering method. Due to the varying sizes of the bayberries, uneven crushing easily clogs the filter screen and results in incomplete separation of pulp and liquid, affecting juicing efficiency and juice purity. Therefore, this invention provides a multi-stage screening, crushing, and juicing device for bayberries. By combining multi-stage screening, efficient crushing, and multi-stage filtration, it achieves uniform feeding of bayberries, thorough crushing, and separation of pulp and liquid. Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the structure of a multi-stage screening, crushing, and juicing device for bayberries provided in an embodiment of this utility model; Figure 2 This is a structural cross-sectional view (first view) of the multi-stage screening, crushing, and juicing device for bayberries provided in this embodiment of the utility model; Figure 3 This is a structural cross-sectional view (second view) of the bayberry multi-stage screening, crushing and juicing device provided in this embodiment of the utility model; Figure 4 This is a structural schematic diagram of the first-stage filter plate or the second-stage filter plate provided in the embodiments of this utility model.

[0020] In this embodiment, the bayberry multi-stage screening, crushing and juicing device includes: a housing 1, a multi-stage screening mechanism 2, a crushing mechanism 3 and a two-stage filtration assembly 4. Specifically, a multi-stage screening mechanism 2 is connected to the top of the casing 1. The multi-stage screening mechanism 2 includes a screening cylinder 21 and screening plates 22. The multi-stage screening plates 22 are arranged sequentially from top to bottom inside the screening cylinder 21 and rotate under the drive of the screening cylinder 21. Each of the multi-stage screening mechanisms 2 is provided with screening holes, and the diameter of the screening holes decreases sequentially from top to bottom along the feeding direction of the bayberry fruit. A crushing mechanism 3 is provided below the multi-stage screening mechanism 2 inside the casing 1. The crushing mechanism 3 includes at least one crushing motor 31 and at least two crushing rollers 32 driven by the crushing motor 31, which are used to crush the bayberry fruit by rolling. A two-stage filtration assembly 4 is provided below the crushing mechanism 3, including a first-stage filter plate 41 and a second-stage filter plate 42. Both the first-stage filter plate 41 and the second-stage filter plate 42 are inclined, and the first-stage filter plate 41 is located above the second-stage filter plate 42. The principle is that the multi-stage screening mechanism 2 is used to screen bayberry fruits. The screened bayberry fruits enter and are crushed by the crushing roller 32 of the crushing mechanism 3. The crushed products are filtered by the two-stage filter assembly 4. The filtered bayberry juice is discharged from the juice outlet 11 at the bottom of the machine casing 1, and the residue is discharged from the residue outlet 12 near the first-stage filter plate 41 and the second-stage filter plate 42 respectively.

[0021] In one optional embodiment, the screening cylinder 21 of the multi-stage screening mechanism 2 is cylindrical, and the screening plate 22 in the multi-stage screening mechanism 2 is an inverted conical structure. The multi-stage inverted conical screening plate 22 is fixedly installed on the inner wall of the screening cylinder 21 to form at least two screening areas with different screening hole sizes. The screening motor is connected to the screening cylinder 21 through a transmission mechanism to drive the screening cylinder 21 to rotate.

[0022] For example, the screening cylinder 21 is driven to rotate intermittently by a screening motor. When the screening cylinder 21 rotates, the bayberry fruits move centrifugally and pass through the corresponding screening holes. When the screening cylinder 21 stops rotating, the bayberry fruits gather towards the center along the inverted conical structure of the screening plate 22, which also allows them to pass through the corresponding screening holes while preventing the bayberry fruits from accumulating inside the screening cylinder 21. That is, the bayberry fruits roll on the screening plate 22 by centrifugation, and the layered setting of the screening hole size allows the bayberry fruits to be screened a second time in the next layer of screening holes after falling through the screening hole once. Since the screening cylinder 21 rotates intermittently, the screening process of the two layers of screening plates 22 can be repeated.

[0023] Specifically, the screening cylinder 21 of the multi-stage screening mechanism 2 has a cylindrical structure, and the multi-stage screening mechanism 22 is an inverted cone shape. The inverted cone-shaped screening plate 22 is fixed to the inner wall of the screening cylinder 21 by bolts or welding, forming multiple screening areas with different screening hole sizes. One end of the screening cylinder 21 is connected to the output shaft of the screening motor through a coupling. The screening motor is fixed to the outer wall of the housing 1 by a bracket. The screening cylinder 21 rotates intermittently under the drive of the screening motor. When the screening cylinder 21 rotates, the bayberry fruits move outward under the action of centrifugal force and pass through the corresponding screening holes. When the screening cylinder 21 stops rotating, the bayberry fruits that have not passed through the screening holes gather towards the center along the inverted cone-shaped surface of the screening plate 22 under the action of gravity. This allows the bayberries to redistribute under the action of gravity, avoiding blockage and preparing for the next centrifugal screening. The intermittent rotation process, combined with the decreasing sieve hole size from top to bottom, achieves multi-stage orderly grading of bayberry fruits from large to small.

[0024] In one optional embodiment, at least two crushing rollers 32 are arranged in parallel, and the distance between adjacent crushing rollers 32 is adjustable. The crushing motor 31 is connected to the crushing rollers 32 via gear transmission or chain transmission to drive the crushing rollers 32 to rotate relative to each other to squeeze and crush the bayberry fruits falling between them.

[0025] For example, the spacing between adjacent crushing rollers 32 can be adjusted by adjusting screws. One end of the adjusting screw is connected to the bearing seat of the crushing roller 32, and the other end passes through the side wall of the housing 1 and is provided with a locking nut. The crushing roller 32 is connected to the crushing roller 32 via chain drive or gear drive to drive the crushing roller 32 to rotate relative to each other.

[0026] For example, the surface of the crushing roller 32 is provided with multiple sets of crushing teeth and crushing protrusions, and the crushing teeth and protrusions are all distributed in a spiral or staggered pattern. Preferably, the height of the crushing teeth can gradually change along the axial direction of the crushing roller 32 to accommodate bayberry fruits of different sizes and to control the particle size of the crushed fruit, thereby optimizing the juice yield and juice quality. Understandably, the hardness of the crushing teeth and protrusions should be higher than that of the bayberry pulp to achieve efficient crushing and avoid over-crushing of the bayberry pit.

[0027] In an optional embodiment, the first-stage filter plate 41 and the second-stage filter plate 42 of the two-stage filter assembly 4 are both provided with mesh-like or slit-like filter holes. The tilt angle of the first-stage filter plate 41 and the tilt angle of the second-stage filter plate 42 are adjustable and are respectively connected to the slag outlet 12 located on different side walls of the housing 1 to change the residence time and moving speed of the material on the filter plate, thereby balancing the processing efficiency and filtration effect and adapting to the needs of different processing volumes.

[0028] Preferably, the first-stage filter plate 41 and the second-stage filter plate 42 are respectively connected to the inner wall of the housing 1 via hinges, and the other end of the hinge is provided with a spring to provide cushioning.

[0029] Preferably, the edges of both the first-stage filter plate 41 and the second-stage filter plate 42 are provided with retaining edges to prevent juice from overflowing.

[0030] For example, the pore sizes of the first-stage filter plate 41 and the second-stage filter plate 42 are different, and each of the first-stage filter plate 41 and the second-stage filter plate 42 of the two-stage filter assembly 4 is connected to an independent vibration motor. The vibration motor generates vibration waves, causing the broken bayberry product to move on the two filter plates and effectively removing the fruit pulp fibers or residues clogging the filter pores.

[0031] In an optional embodiment, one slag outlet 12 is located on the left side wall of the housing 1, and the other slag outlet 12 is located on the right side wall of the housing 1. Both slag outlets 12 are used to collect the separated slag. The positions of the two slag outlets 12 are staggered to avoid mixing of slag and to provide a longer filtration area and travel distance.

[0032] Preferably, the slag outlet 12 is connected to the side wall of the housing 1 via a flange, and a sealing ring is provided on the flange to prevent leakage.

[0033] In an optional embodiment, a guide plate 5 is provided between the lower part of the multi-stage screening mechanism 2 and the upper part of the crushing mechanism 3. The guide plate 5 is fixed to the inner wall of the housing 1 and is inclined to guide the screened bayberry fruits into the crushing mechanism 3.

[0034] For example, the tilt angle of the guide plate 5 can be set to 30° to 45°. One end of the guide plate 5 is connected to the bottom of the housing 1 by bolts, and the other end faces the feed end of the crushing mechanism 3. In this way, the tilted guide plate 5 can ensure that the screened bayberry fruits slide into the crushing mechanism 3 automatically and centrally by gravity, avoiding material accumulation and jamming, and realizing a seamless automated connection from screening to crushing.

[0035] In an optional embodiment, the housing 1 and the multi-stage screening mechanism 2 are each provided with a removable sealing cover. The removable sealing cover is connected to the housing 1 or the screening cylinder 21 by quick-release buckles or bolts to facilitate the cleaning, inspection, and maintenance of the internal mechanism. In addition, a sludge collection tank can be provided at the bottom of the housing 1, and a sludge discharge pipe can be connected to it to discharge wastewater during the cleaning of the internal mechanism and to collect dripping bayberry juice and fallen material residue.

[0036] Preferably, a sealing gasket made of silicone is provided on the inner side of the sealing cover; a handle can also be provided on the outer side of the sealing cover, which is connected to the sealing cover by bolts to facilitate disassembly and cleaning.

[0037] It is worth noting that in this embodiment, the multi-stage screening, crushing, and juicing device for bayberries has a multi-stage screening mechanism 2 that grades the bayberry fruit through a multi-stage screening plate 22. The aperture of the screening plate 22 gradually decreases along the feeding direction to ensure that bayberry fruit of different sizes can be screened step by step. The crushing mechanism 3 crushes the screened bayberry fruit through multiple crushing rollers 32. The crushing teeth and protrusions on the surface of the crushing rollers 32 improve the crushing efficiency, and the spacing between adjacent crushing rollers 32 is adjustable to accommodate the particle size of bayberry fruit of different sizes. The two-stage filtration assembly 4 separates the crushed products through a first-stage filter plate 41 and a second-stage filter plate 42. The filter holes of different apertures can effectively separate the pit, pulp, and juice, avoiding the problem of difficult separation in traditional single-stage filtration. A guide plate 5 is provided between the multi-stage screening mechanism 2 and the crushing mechanism 3 to ensure that the screened bayberry fruit can smoothly enter the multi-stage screening mechanism 2, reducing manual intervention. This structure allows the bayberry fruit to undergo multi-stage screening, crushing, and grading filtration, enabling continuous operation from raw material to finished product. It solves the problems of high labor intensity and low efficiency in traditional juicing methods, while avoiding residue clogging the filter screen and improving the purity of the juice and the efficiency of subsequent processing.

[0038] This utility model discloses a multi-stage screening, crushing, and juicing device for bayberries. Through a multi-stage screening mechanism, the bayberry fruits are graded to ensure uniform particle size before entering the crushing zone, thus improving crushing efficiency and juice yield. The crushing mechanism employs a toothed roller structure to enhance the crushing effect and avoid uneven crushing caused by particle differences. A two-stage filtration system, combined with a vibrating motor design, effectively prevents filter clogging, achieving thorough separation of the pit, pulp, and juice, significantly improving juice purity and juicing efficiency. The overall structure is compact, easy to operate, and can run continuously, making it suitable for large-scale production.
