Description

Technical Field

[0001] This utility model relates to the field of jujube processing technology, specifically a screening device for jujube processing that can perform multi-stage screening. Background Technology

[0002] Jujube, scientifically known as Ziziphus jujuba, is a plant belonging to the genus Ziziphus of the family Rhamnaceae. There are many varieties of jujube, differing in fruit size, shape, and taste. Jujubes are rich in various nutrients, containing sugars, vitamins, and minerals. Processed jujube products often have different size requirements. A screening device can select jujubes that meet specific processing requirements, ensuring consistent product quality. The screening device mainly consists of an inlet, screens, a vibrating motor, and an outlet. The inlet guides the jujube raw materials into the screens, which are typically multi-layered with different mesh sizes to separate jujubes of different specifications. The vibrating motor is the core power component of the device; it generates high-frequency vibrations to make the screens vibrate up and down, left and right, or in a circular direction. However, existing jujube processing screening devices cannot perform multi-stage screening of jujubes and are inconvenient to remove after screening, making them rather cumbersome to use. Utility Model Content

[0003] The purpose of this utility model is to provide a screening device for jujube processing that can perform multi-stage screening, so as to solve the problems mentioned in the background art that it is not possible to perform multi-stage screening of jujubes and that it is inconvenient to take out the screened jujubes, making it inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a screening device for jujube processing capable of multi-stage screening, comprising a shell, wherein the shell is configured as an open square shell, and a feeding trough is fixedly connected to the surface of the shell;

[0005] The bottom of the feeding trough is provided with multiple feeding ports, and the bottom of the feeding trough is continuously provided with multiple diversion channels. The inner wall of the outer shell is provided with filter plate one and filter plate two.

[0006] The housing has an internal filtration structure, which includes: rotating rods symmetrically connected to the surfaces of filter plate one and filter plate two, with the ends of the rotating rods inserted into the inner wall of the housing; a cylinder mounted on the inner wall of the housing, with the output shaft end of the cylinder connected to the bottom of filter plate two; a push rod connected to the surface of filter plate two, with the end of the push rod connected to the bottom of filter plate one; rubber buffer blocks symmetrically connected to the inner wall of the housing; rubber blocks mounted at the ends of filter plate one and filter plate two; a guide groove embedded in the inner wall of the housing; and a partition plate connecting the guide groove and the rubber block.

[0007] Preferably, the discharge port and the diversion channel are positioned correspondingly, and the diversion channel is located at the opening of the outer shell.

[0008] Using the above technical solution, jujubes enter the inside of the flow channel through the feeding port. The surface of the flow channel is provided with feeding holes. The surface of the filter plate two is embedded with feeding holes, and the diameter of the holes in the filter plate one is larger than the diameter of the holes in the filter plate two.

[0009] Using the above technical solution, filter plate one and filter plate two are used to screen jujubes of different diameters.

[0010] Preferably, the first filter plate and the second filter plate are rotatably connected to the inner wall of the outer casing, and the rotating rod is rotatably connected to the outer casing.

[0011] Using the above technical solution, when the cylinder pushes one side of filter plate one and filter plate two upward, filter plate one and filter plate two can drive the rotating rod to rotate inside the outer shell.

[0012] Preferably, the guide grooves are respectively disposed at the bottom of filter plate one and filter plate two, and the cross-section of the guide grooves is set as an L-shaped groove, and the end of the guide grooves is disposed on the outside of the outer shell, and the guide grooves are disposed at the bottom of the rubber block.

[0014] Preferably, the second filter plate is disposed at the bottom of the first filter plate, and the surface of the rubber buffer block is respectively attached to the bottom of the first filter plate and the second filter plate.

[0015] Using the above technical solution, filter plate one first filters the jujubes, and the jujubes with smaller pulp fall onto the surface of filter plate two.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this screening device for jujube processing can perform multi-stage screening.

[0017] 1. A filtration mechanism is set up. The cylinder pushes filter plate one and filter plate two to move upward simultaneously, vibrating them to filter the jujubes multiple times. After the filter plates are in place, the cylinder pushes filter plate one and filter plate two to rotate, causing the jujubes on the surface of filter plate one and filter plate two to fall into the guide groove for collection, thus improving the practicality of the device.

[0018] 2. An inlet and outlet are provided. Jujubes can be poured into the inlet and diverted through the outlet to the surface of the filter plate, which can improve the filtration effect of the jujubes. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a screening device for jujube processing that can perform multi-stage screening, including a shell 10, a feeding trough 20, a discharge port 201, a diversion trough 202, a first filter plate 30, a rotating rod 40, a cylinder 401, a push rod 402, a rubber buffer block 403, a rubber block 404, a partition 405, a guide groove 406, and a second filter plate 50;

[0031] This jujube processing screening device facilitates the diversion of jujubes during input. The specific implementation method is as follows:

[0032] The outer shell 10 is an open square shell, and a feed trough 20 is fixedly connected to the surface of the outer shell 10. Multiple discharge ports 201 are embedded in the bottom of the feed trough 20, and multiple diversion channels 202 are continuously installed at the bottom of the feed trough 20. A filter plate 30 and a filter plate 50 are embedded in the inner wall of the outer shell 10. The positions of the discharge ports 201 and the diversion channels 202 are correspondingly set, and the diversion channels 202 are set at the opening of the outer shell 10.

[0033] The jujubes are poured into the feed trough 20. The jujubes in the feed trough 20 enter the feed trough 20 and then enter the diversion trough 202. They move downwards in the diversion trough 202 and fall into the shell 10. The jujubes land on the surface of the filter plate 30 and move downwards through multiple diversion troughs 202 to distribute the jujubes more evenly on the surface of the filter plate 30, preventing the jujubes from accumulating on the surface of the filter plate 30.

[0034] This jujube processing screening device facilitates the filtering and collection of jujubes. The specific implementation method is as follows:

[0035] The housing 10 has an internal filter structure, which includes: a rotating rod 40 symmetrically connected to the surfaces of a first filter plate 30 and a second filter plate 50, with the ends of the rotating rods 40 inserted into the inner wall of the housing 10; a cylinder 401 mounted on the inner wall of the housing 10, with the output shaft of the cylinder 401 connected to the bottom of the second filter plate 50; a push rod 402 connected to the surface of the second filter plate 50, with the end of the push rod 402 connected to the bottom of the first filter plate 30; rubber buffer blocks 403 symmetrically connected to the inner wall of the housing 10; rubber blocks 404 mounted at the ends of both the first filter plate 30 and the second filter plate 50; a guide groove 406 embedded in the inner wall of the housing 10; and a partition 405 connecting the guide groove 406 and the rubber blocks 404. The surface of filter plate 30 is provided with a discharge hole, and the surface of filter plate 50 is embedded with a discharge hole. The diameter of the holes in filter plate 30 is larger than that in filter plate 50. Filter plate 30 and filter plate 50 are rotatably connected to the inner wall of housing 10. Rotating rod 40 is rotatably connected to housing 10. Guide grooves 406 are respectively provided at the bottom of filter plate 30 and filter plate 50. The cross-section of guide groove 406 is set as an L-shaped groove. The end of guide groove 406 is located on the outside of housing 10. Guide groove 406 is located at the bottom of rubber block 404. Filter plate 50 is located at the bottom of filter plate 30. The surface of rubber buffer block 403 is in contact with the bottom of filter plate 30 and filter plate 50 respectively.

[0036] When the jujube falls onto the surface of filter plate 30, cylinder 401 is activated. The output shaft of cylinder 401 pushes, causing one side of filter plate 30 to move up and down. Filter plate 30, through push rod 402, drives one side of filter plate 50 to move upward, causing both filter plates 30 and 50 to vibrate simultaneously. At this time, filter plates 30 and 50 drive the rotating rod 40 to rotate, causing the rotating rod 40 to rotate inside the outer casing 10. Meanwhile, the outer sides of filter plates 30 and 50 rotate on the inner wall surface of the outer casing 10, causing one side of filter plates 30 and 50 to vibrate... The surface of the rubber buffer block 403 vibrates, causing the smaller-diameter dates on the surface of the filter plate 30 to fall through the holes, while the larger-diameter dates remain on the surface of the filter plate 30 and fall onto the surface of the filter plate 50. The dates are then filtered a second time by the filter plate 50, causing the smaller-diameter dates to fall, while the larger-diameter dates remain on the surface of the filter plate 50 and fall onto the inner bottom surface of the outer shell 10. They then slide down the inner bottom surface of the outer shell 10 to the outer side of the outer shell 10. Due to the obstruction of the partition 405, the dates will not enter the guide groove 406.

[0037] After the jujubes are filtered, cylinder 401 can be activated, causing the end of cylinder 401 to push filter plate 30 and filter plate 50 upwards simultaneously. At this time, filter plate 30 and filter plate 50 drive the rotating rod 40 to rotate, causing filter plate 30 and filter plate 50 to tilt. The other end of filter plate 30 and filter plate 50 moves downwards, causing the rubber block 404 to move downwards, causing the end of the rubber block 404 to lose contact with the outer shell 10. At this time, a gap is created between the rubber block 404 and the outer shell 10. The rubber block 404 then causes the partition plate 405 to contract, causing the rubber block 404 to rotate to the top of the guide groove 406. At this time, the jujubes fall down along the surface of filter plate 30 and filter plate 50, allowing the jujubes to pass through filter plate 30 and filter plate 50 and fall into the inside of the guide groove 406, thus exporting the jujubes.

[0038] Working principle: When using this screening device for jujube processing that can perform multi-stage screening, an inlet 20, a discharge port 201, and a diversion trough 202 are set up to facilitate the diversion of jujubes when they are fed in. Rubber blocks 404, partitions 405, guide troughs 406, and filter plates 50 are set up to facilitate the filtration and collection of jujubes, increasing the overall practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
