Description

Technical Field

[0001] This utility model relates to the field of wine production technology, specifically to a vibrating screen for selecting raw materials for winemaking. Background Technology

[0002] In the processing of wine grapes, grape bunch selection is an important preliminary step. High-quality wine grapes require destemming, removal of diseased, rotten, and impurity fruits to ensure the quality of the wine.

[0003] Existing grape bunch sorting equipment, after separating the berries from the stems, primarily uses a vibrating screen to remove diseased, rotten, and impurity berries. The berries are then conveyed by multiple parallel rollers, with the berries falling through the gaps between the rollers and the stems being transported outwards. However, this type of bunch sorting equipment has certain limitations. Firstly, it is not suitable for grapes of different sizes, requiring different roller spacing structures, resulting in poor adaptability. Secondly, grapes may become stuck between the rollers, causing breakage. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the present invention provides a vibrating screen for selecting raw materials for winemaking, which can effectively solve the technical problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] A vibrating screen is used to select raw material ears for winemaking, comprising:

[0007] frame;

[0008] The destemming mechanism includes a hopper installed on the upper front side of the frame. Inside the hopper, there is a set of relatively synchronously swinging drive components in a grid shape, and three sets of actuating components connected by corresponding gears. The actuating components sequentially transfer the material up and down and cooperate with the two synchronously swinging drive components to separate the fruit particles and stems of the material.

[0009] A vibrating sieving mechanism for sieving to remove fine impurities and necrotic fruit includes a screening support platform movably mounted on a frame located below the discharge port of the destemming mechanism, and a drive assembly for driving the screening support platform to vibrate and sieve. At least one screen is detachably and fixedly mounted on the screening support platform.

[0010] The stem guiding mechanism includes a grid-shaped guide component that is hinged and oscillatingly mounted on a frame located in front of the discharge end of the vibrating screening mechanism. The guide component includes a plurality of grid bars arranged side by side at intervals. The guide component is inclined downward in the direction away from the direction of grape berry conveying and extends to a distance from the upper surface of the screening support platform. A stem conveyor belt for conveying grape stems outward is provided below the upwardly inclined end of the guide component.

[0011] The stem-pulling mechanism includes a hollow roller rotatably mounted below the guide member. The surface of the hollow roller may be fitted with a lever that is interleaved with the railings on the guide member. The outer end of the lever extends outward and passes through the guide member. When the hollow roller drives the lever to rotate, it pushes the stems intercepted by the guide member upward and transmits them to the stem conveyor belt.

[0012] The driving component is driven by a corresponding electric motor to rotate the cam, which in turn causes the driving component to swing. The actuating assembly includes a drive shaft and a number of dials that are fixedly mounted on the drive shaft at lateral intervals. The dials are staggered with the grid plates on the driving component. The dials located at the same position on the three drive shafts are arranged to rotate crosswise. The material is received sequentially by the rotation of multiple sets of cross dials in the three actuating assemblies, and the grape berries and stems are separated by a set of driving components pushing them left and right.

[0013] The inner end of the actuating rod is movably inserted through the hollow roller and fixed to a corresponding iron component. A corresponding magnetic suction component is horizontally fixed inside the hollow roller. The two ends of the magnetic suction component extend outward through the hollow roller and are fixed to both sides of the frame. The distance and thickness between the magnetic suction component and the inner surface of the hollow roller gradually increase in the clockwise direction. When the hollow roller rotates clockwise, under the magnetic attraction of the magnetic suction component to the iron component, the actuating rod gradually retracts into the hollow roller and keeps the outer end of the actuating rod inserted into the guide component. When the actuating rod rotates to the top of the hollow roller, that is, when the actuating rod is at the position where the thickness of the magnetic suction component is the largest, the actuating rod retracts to the outer end and disengages from the guide component. When the vibrating screening mechanism is activated, it transmits the material to its outlet. The guide component intercepts the stalks on the screening platform and is gradually lifted and conveyed to the stalk conveyor belt by the rotating actuating rod.

[0014] A corresponding limiting tube is fixedly installed on the outer surface of the hollow roller. The actuating rod is telescopically inserted into the limiting tube. A corresponding second elastic element is sleeved on the outer side of the actuating rod between the iron part and the hollow roller. The two ends of the second elastic element are respectively fixed to the inner wall of the hollow roller and the iron part. A corresponding abutting ball is rotatably installed on the side of the iron part facing the magnetic attractor.

[0015] The guide component includes a support roller shaft rotatably mounted on the frame. The grid bars are horizontally and equally spaced, inclined downwards and fixed to the support roller shaft. The end of the grid bar not connected to the support roller shaft extends downwards and is fitted with a corresponding flexible protective sleeve. The distance between the end of the grid bar fitted with the flexible protective sleeve and the screening support platform is greater than D1 and less than D2, where D1 is the diameter of the grape berries and D2 is twice the diameter of the grape berries.

[0016] The upper ends of both sides of the guide are provided with corresponding reset mechanisms. The reset mechanism includes a support plate fixed to the frame. A first elastic element is connected between the support plate and the outermost fence bar. The first elastic element causes the guide to have a tendency to swing up and down.

[0017] An arc-shaped catalytic plate is fixedly installed on the guide component below the support roller shaft. When the actuating rod rotates to the top of the hollow roller, i.e., when the actuating rod is at the position where the magnetic suction component is at its thickest, the distance between the outer end of the actuating rod and the outer surface of the hollow roller is greater than the distance between the catalytic plate and the outer surface of the hollow roller. That is, when the actuating rod rotates, it pushes the catalytic plate.

[0018] An auxiliary material-pushing mechanism is provided above the feed end of the guide component. The auxiliary material-pushing mechanism includes a rotating roller connected to the hollow roller via gear meshing. The rotation direction of the rotating roller is opposite to that of the hollow roller. Multiple material-pushing components are fixedly connected at equal intervals on the circumferential surface of the rotating roller. Multiple material-pushing rods are arranged side by side at equal intervals on the material-pushing components. The material-pushing rods, guardrails, and actuating rods are arranged alternately on the left and right sides. The material-pushing rods and actuating rods are arranged crosswise.

[0019] The screening support platform is mounted on the frame by at least four support spring columns installed at its end corners. The drive assembly includes a vibration motor installed below the screening support platform and / or a frequency converter regulating motor fixedly installed on the frame. The output shaft end of the frequency converter regulating motor is fixedly mounted with a corresponding eccentric wheel, and the eccentric wheel abuts against the bottom of the screening support platform.

[0020] The vibrating screen also includes a material receiving mechanism for receiving materials. The material receiving mechanism includes a collection trough fixedly on the frame located below the screen and a material receiving frame located below the discharge end of the screening platform. The side and bottom of the collection trough are connected with corresponding ball valves. Two screens are detachably and fixedly installed on the front and rear of the screening platform. The welded strips of the screens are trapezoidal strips that are wider at the top and narrower at the bottom.

[0021] Advantages of this utility model:

[0022] 1) The stem-guiding mechanism of this utility model uses corresponding guide components that are oscillating at intervals on the screening platform. When the material vibrates up and down and is conveyed towards the discharge port, the long, irregularly shaped stems are easily intercepted by the grid-like guide components. The fruit continues to be conveyed forward, and after further vibration and sieving, some fine impurities and rotten fruit are directly collected. Below the stem-guiding mechanism is a stem-removing mechanism, which includes a hollow roller driven by a motor. The surface of the hollow roller is equipped with a lever that is staggered with the grid of the guide components. The rotation of the lever can gradually convey the stems on the lever to the stem conveyor belt at the top, thereby effectively separating the stems from the fruit and conveying them outward. Based on the stem-removing mechanism for separating fruit and stems, and the vibrating screening mechanism for separating fine impurities and rotten fruit, the addition of the stem-guiding and stem-removing mechanisms to remove stems replaces the traditional multi-layer graded guide roller method for separating fruit. This effectively solves the problems of incomplete fruit separation and fruit getting stuck between the guide rollers and causing damage.

[0023] 2) Since the rotating stick-pulling mechanism and the stick-guiding mechanism work together to separate and transfer sticks, the length of the actuating rod needs to be extended to ensure the stick-pulling effect. However, an excessively long actuating rod is prone to jamming at the top of the stick-guiding mechanism and failing to operate. Therefore, this utility model further installs the actuating rod telescopically inside the hollow roller, and fixes a corresponding magnet inside the hollow roller. The distance and thickness between the magnet and the inner surface of the hollow roller gradually increase in the clockwise direction. During the rotation of the actuating rod, the iron part installed at its end is attracted by the magnet, which in turn drives the rotating actuating rod to gradually retract into the hollow roller. When the actuating rod rotates to the top of the hollow roller, that is, when the actuating rod is at the position where the thickness of the magnet is the greatest, the actuating rod retracts to the outer end and disengages from the guide. This effectively avoids the jamming problem when the stick-guiding mechanism and the stick-pulling mechanism are running, improves the adaptability of the equipment, and ensures the smooth operation and practical effect of this utility model.

[0024] 3) In this utility model, an arc-shaped triggering plate is fixedly installed on the guide component below the support roller shaft. When the actuating rod rotates to the top of the hollow roller, the actuating rod continues to rotate and pushes the triggering plate, thereby causing the guide component to swing downward. Furthermore, a corresponding first elastic element is connected between the outermost grid bar on the guide component and the frame. The guide component swings downward and, under the elastic force of the first elastic element, drives the guide component to swing up and down, thereby forming a certain swing amplitude at the downward tilting end of the guide component. This, together with the vibrating screening platform, flattens and loosens the material, allowing the fruit particles to be transferred evenly and in a single layer, thereby promoting and improving the efficiency and effect of subsequent vibrating screening.

[0025] 4) This utility model allows for the telescopic installation of a lever through the cooperation of a second elastic element and a limiting tube. A corresponding iron component is provided at the end of the lever, and the magnetic attraction of a non-standard component allows the lever to be gradually attracted and retracted into the hollow roller during rotation, ensuring smooth disengagement from the guide component. Furthermore, corresponding abutting balls are rotatably installed on the iron component. When the iron component is attracted and abuts against the magnetic component, the intervention of the abutting balls effectively reduces the resistance of the lever during rotation with the hollow roller, further improving the practical effect of this utility model.

[0026] 5) Due to limitations in the length of the actuating rod of the stalk-pulling mechanism, material at the feed end of the guide component tends to accumulate because it cannot be promptly pushed upwards by the actuating rod. Therefore, this invention further adds an auxiliary actuating mechanism. The auxiliary actuating mechanism includes a rotating roller whose rotation direction is opposite to that of the hollow roller. Multiple rows of stalk-pulling rods are installed on the rotating roller. The stalk-pulling rods, the grid bars, and the actuating rods are arranged alternately on the left and right sides, and the stalk-pulling rods and the actuating rods are arranged crosswise. The grid bars intercept and gather the stalks being transported, and the rotating stalk-pulling rods push the intercepted stalks upwards along the grid bars. Because the actuating rods are arranged alternately and crosswise with the stalk-pulling rods, they rotate in the opposite direction from below the stalk-pulling rods to receive the stalks on the stalk-pulling rods and continue to push them along the direction of the grid bars. This not only allows the stalks to be continuously conveyed along the direction of the grid bars, but also allows the actuating rods to effectively receive the stalks on the stalk-pulling rods, preventing the stalks from returning to the screening platform as the stalk-pulling rods rotate, further ensuring the practical effect of this invention.

[0027] 6) This utility model's vibrating sieving mechanism can be equipped with two screens, one at the front and one at the back. The front screen performs preliminary sieving and separates the stems before further vibrating and sieving, thereby improving the efficiency and quality of sieving and ensuring that the grapes are sieving more comprehensively. Diseased, rotten, moldy, and other unusable materials can be more thoroughly separated. The screens are detachably mounted on the sieving platform for easy cleaning. The welded strips of the screens are trapezoidal strips, wider at the top and narrower at the bottom, to prevent clogging when small grapes enter the screens. The sieving platform can generate composite vibrations in both vertical and horizontal directions through a combination of a vibrating motor and an eccentric wheel, allowing the grapes to tumble and disperse fully on the platform, improving the sieving effect. The eccentric wheel is connected to a variable frequency motor, and the motor speed can be adjusted by the frequency converter to control the frequency and intensity of vibration, further improving the vibration effect and promoting the sieving of grapes. This utility model has a collection trough below the screens to collect residues and juices, facilitating centralized cleaning. The sides and bottom of the collection trough are equipped with corresponding ball valves for discharging grape juice and dirty water from washing. Attached Figure Description

[0034] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0035] refer to Figure 1-5 A vibrating screen is used to process raw materials for winemaking, comprising:

[0036] Rack 1;

[0037] The destemming mechanism 2 includes a hopper 201 installed on the upper front side of the frame 1. A set of relatively synchronously swinging drive members 202 in the form of a grid are rotatably installed in the hopper 201, and three sets of actuating components connected by corresponding gears. The actuating components sequentially transfer the material up and down and cooperate with the two synchronously swinging drive members 202 to separate the fruit particles and stems of the material.

[0038] The vibrating sieving mechanism 3 is used to sieve and remove fine impurities and necrotic fruits. It includes a screening support platform 301 that is movably installed on a frame 1 located below the discharge port of the destemming mechanism 2, and a drive assembly 302 for driving the screening support platform 301 to vibrate and sieve. At least one screen 303 is detachably and fixedly installed on the screening support platform 301.

[0039] The stem guiding mechanism 4 includes a grid-shaped guide component 401 that is hinged and oscillatingly mounted on a frame 1 located in front of the discharge end of the vibrating screening mechanism 3. The guide component 401 includes a plurality of grid bars 4013 arranged side by side at intervals. The guide component 401 is inclined downward in the direction away from the direction of grape berry conveying and extends to a distance from the upper surface of the screening support platform 301. A stem conveyor belt 402 for conveying grape stems outward is provided below the upwardly inclined end of the guide component 401.

[0040] The stem-pulling mechanism 5 includes a hollow roller 501 rotatably mounted below the guide member 401. The surface of the hollow roller 501 may be equipped with a lever 502 that is interleaved with the guardrail bars 4013 on the guide member 401. The outer end of the lever 502 extends outward and passes through the guide member 401. When the hollow roller 501 drives the lever 502 to rotate, it pushes the stems intercepted by the guide member 401 upward and transmits them to the stem conveyor belt 402.

[0041] The driving component 202 is driven by a corresponding electric motor to rotate the cam, which in turn causes the driving component 202 to swing. The actuating assembly includes a drive shaft and a number of dial wheels 203 that are fixedly mounted on the drive shaft at lateral intervals. The dial wheels 203 are staggered with the grid plates on the driving component 202. The dial wheels 203 located at the same position on the three drive shafts are arranged to rotate crosswise. The multiple sets of cross dial wheels 203 in the three actuating assemblies rotate to receive the material in sequence, and the grape berries and stems are separated by a set of driving components 202 pushing them left and right.

[0042] The inner end of the actuating lever 502 is movably inserted through the hollow roller 501 and fixed to a corresponding iron component 503. A corresponding magnetic component 504 is horizontally fixed inside the hollow roller 501. Both ends of the magnetic component 504 extend outwards through the hollow roller 501 and are fixed to both sides of the frame 1. The distance and thickness between the magnetic component 504 and the inner surface of the hollow roller 501 gradually increase in a clockwise direction. When the hollow roller 501 rotates clockwise, the magnetic attraction of the magnetic component 504 on the iron component 503 causes the actuating lever 502 to... The lever 502 gradually retracts into the hollow roller 501 while keeping the outer end of the lever 502 inserted into the guide member 401; when the lever 502 rotates to the top of the hollow roller 501, i.e., when the lever 502 is at the position where the thickness of the magnetic suction member 504 is the greatest, the lever 502 retracts to the outer end and disengages from the guide member 401; when the vibrating screening mechanism 3 operates, it transmits the material to its outlet, and the guide member 401 intercepts the stalks on the screening support platform 301 and is gradually lifted and conveyed to the stalk conveyor belt 402 by the rotating lever 502.

[0043] The stem guiding mechanism 4 of this utility model has corresponding guide members 401 that are oscillating at intervals on the screening and bearing platform 301. When the material vibrates up and down and is conveyed to the discharge port, the long and irregular stem strips are easily intercepted by the fence-like guide members 401. The fruit continues to be conveyed forward and further vibrates through the sieve, and some fine impurities and rotten fruit are directly collected. Below the stem guiding mechanism 4, a stem pulling mechanism 5 is set. The stem pulling mechanism 5 includes a hollow roller 501 that is driven to rotate by a motor. The surface of the hollow roller 501 is provided with a lever 502 that is extended and retractable and is interposed with the fence strips 4013 of the guide members 401. The rotation of the lever 502 can gradually convey the stem strips on the lever 502 to the stem conveyor belt at the top, thereby effectively separating the stem strips from the fruit and conveying them outward. Based on the separation of fruit grains and stems by the destemming mechanism 2 and the screening and separation of fine impurities and necrotic fruit by the vibrating screening mechanism 3, the stem removal mechanism 4 and the stem removal mechanism 5 are added to replace the traditional multi-layer graded guide roller separation method for fruit grains. This effectively solves the problems of inadequate fruit grain separation and fruit grains easily getting stuck between the guide rollers and causing damage.

[0044] Since the rotating stem-pulling mechanism 5 cooperates with the stem-guiding mechanism 4 to separate and transmit stems, the length of the actuating rod 502 needs to be extended to ensure the stem-pulling effect. However, an excessively long actuating rod 502 is prone to jamming at the top of the stem-guiding mechanism 4 and failing to operate. Therefore, this utility model further extends and retracts the actuating rod 502 within the hollow roller 501, and fixes a corresponding magnet 504 within the hollow roller 501. The distance and thickness between the magnet 504 and the inner surface of the hollow roller 501 gradually increase in a clockwise direction. During the rotation of the actuating rod 502, its end is equipped with... The iron part 503 is attracted by the magnet 504. The distance and thickness between the magnet 504 and the inner surface of the hollow roller 501 gradually increase in the clockwise direction, which in turn drives the rotating actuating rod 502 to gradually retract into the hollow roller 501. When the actuating rod 502 rotates to the top of the hollow roller 501, that is, when the actuating rod 502 is at the position where the thickness of the magnet 504 is the greatest, the actuating rod 502 retracts to the outer end and disengages from the guide part 401. This effectively avoids the jamming problem of the guide mechanism 4 and the actuating mechanism 5 during operation, improves the adaptability of the equipment, and ensures the smooth operation and practical effect of this utility model.

[0045] A corresponding limiting tube 505 is fixedly installed on the outer surface of the hollow roller 501. The actuating rod 502 is telescopically inserted into the limiting tube 505. A corresponding second elastic member 506 is sleeved on the outer side of the actuating rod 502 between the iron part 503 and the hollow roller 501. The two ends of the second elastic member 506 are respectively fixed to the inner side wall of the hollow roller 501 and the iron part 503. A corresponding abutting ball 507 is rotatably installed on the side of the iron part 503 facing the magnetic attractor 504.

[0046] This invention utilizes the cooperation of a second elastic element 506 and a limiting tube 505 to telescopically mount a lever 502. A corresponding iron part 503 is provided at the end of the lever 502. Furthermore, the non-standard magnetic attraction element 504 allows the lever 502 to be gradually attracted by the iron part 503 and retracted into the hollow roller 501 during rotation, ensuring smooth disengagement from the guide element 401. A corresponding abutting ball 507 is rotatably mounted on the iron part 503. When the iron part 503 is attracted by the magnetic attraction element 504 and abuts against it, the intervention of the abutting ball 507 effectively reduces the resistance of the lever 502 during rotation with the hollow roller 501, further improving the practical effect of this invention.

[0047] The guide component 401 includes a support roller shaft 4011 rotatably mounted on the frame 1. The guardrail bars 4013 are horizontally and equally spaced, inclined downwards and fixed to the support roller shaft 4011. The end of the guardrail bar 4013 not connected to the support roller shaft 4011 extends downwards and is fitted with a corresponding flexible protective sleeve 4012. The distance between the end of the guardrail bar 4013 fitted with the flexible protective sleeve 4012 and the screening support platform 301 is greater than D1 and less than D2, where D1 is the diameter of the grape berries and D2 is twice the diameter of the grape berries.

[0048] The upper ends of both sides of the guide member 401 are provided with corresponding reset mechanisms 7. The reset mechanism 7 includes a support plate 701 fixed to the frame 1. The support plate 701 is connected to the outermost fence bar 4013 with a corresponding first elastic member 702. The first elastic member 702 causes the guide member 401 to have a tendency to swing up and down.

[0049] An arc-shaped actuating plate 8 is fixedly disposed on the guide member 401 below the support roller shaft 4011. When the actuating rod 502 rotates to the top of the hollow roller 501, that is, when the actuating rod 502 is at the position where the thickness of the magnetic suction member 504 is the greatest, the distance between the outer end of the actuating rod 502 and the outer surface of the hollow roller 501 is greater than the distance between the actuating plate 8 and the outer surface of the hollow roller 501. That is, when the actuating rod 502 rotates, it pushes the actuating plate 8.

[0050] This invention further includes an arc-shaped trigger plate 8 fixedly installed on the guide component 401 below the support roller shaft 4011. When the actuating rod 502 rotates to the top of the hollow roller 501, the actuating rod 502 continues to rotate and pushes the trigger plate 8, thereby causing the guide component 401 to swing downward. Furthermore, the outermost grid bar 4013 on the guide component 401 is connected to the frame 1 by a corresponding first elastic element 702. The guide component 401 swings downward and, under the elastic force of the first elastic element 702, drives the guide component 401 to swing up and down, thereby forming a certain swing amplitude at the downward inclined end of the guide component 401. This, together with the vibrating screening platform 301, flattens and loosens the material, allowing the fruit particles to be transferred evenly and in a single layer, thus promoting and improving the efficiency and effect of subsequent vibrating screening.

[0051] Above the feed end of the guide component 401, there is an auxiliary material-pushing mechanism 9. The auxiliary material-pushing mechanism 9 includes a rotating roller 901 connected to the hollow roller 501 by gear meshing. The rotation direction of the rotating roller 901 is opposite to that of the hollow roller 501. Multiple material-pushing components 902 are fixedly connected at equal intervals on the circumferential surface of the rotating roller 901. Multiple material-pushing rods 9021 are arranged side by side at equal intervals on the material-pushing components 902. The material-pushing rods 9021, the guardrail 4013 and the actuating rod 502 are arranged alternately on the left and right sides. The material-pushing rods 9021 and the actuating rod 502 are arranged crosswise.

[0052] Because the length setting of the actuating rod 502 of the actuating mechanism 5 is limited, the material at the feeding end of the guide 401 is prone to accumulation because it cannot be pushed upward by the actuating rod 502 in time. Therefore, this utility model further adds an auxiliary actuating mechanism 9. The auxiliary actuating mechanism 9 includes a rotating roller 901 whose rotation direction is opposite to that of the hollow roller 501. Multiple rows of actuating rods 902 are installed on the rotating roller 901. The actuating rods 902, the guardrail 4013 and the actuating rod 502 are arranged alternately on the left and right sides, and the actuating rods 902 and the actuating rod 502 are arranged crosswise. The conveyed strands are intercepted and gathered by the barrier bars 4013, and the intercepted strands are pushed upward along the barrier bars 4013 by the rotating feed lever 902. Because the actuating lever 502 is staggered and cross-arranged with the feed lever 902, the actuating lever 502 rotates in the opposite direction from below the feed lever 902 to receive the strands on the feed lever 902 and continue to push them along the direction of the barrier bars 4013. This not only allows the strands to be continuously conveyed along the direction of the barrier bars 4013, but also allows the actuating lever 502 to effectively receive the strands on the feed lever 902, preventing the strands from returning to the screening platform 301 as the feed lever 902 rotates, further ensuring the practical effect of this utility model.

[0053] The screening support platform 301 is mounted on the frame 1 by at least four support spring columns installed at its end corners. The drive assembly 302 includes a vibration motor installed below the screening support platform 301 and / or a frequency converter regulating motor fixedly installed on the frame 1. The output shaft end of the frequency converter regulating motor is fixedly mounted with a corresponding eccentric wheel, and the eccentric wheel abuts against the bottom of the screening support platform 301.

[0054] The vibrating screen also includes a material receiving mechanism 6 for receiving materials. The material receiving mechanism 6 includes a collection trough 601 fixedly on the frame 1 located below the screen 303 and a material receiving frame 602 located below the discharge end of the screening support platform 301. The side and bottom of the collection trough 601 are connected with corresponding ball valves. Two screens 303 are detachably and fixedly installed on the screening support platform 301. The welded strips of the screens 303 are trapezoidal strips that are wider at the top and narrower at the bottom.

[0055] This utility model's vibrating sieving mechanism 3 can be equipped with two screens 303, one at the front and one at the back. The front screen performs preliminary sieving and separates the stems before further vibrating sieving, thereby improving the efficiency and quality of sieving and ensuring that the grapes are sieving more comprehensively. Diseased, rotten, moldy, and other unusable materials can be more thoroughly separated. The screens 303 are detachably mounted on the sieving support platform 301 for easy cleaning. The welded strips of the screens 303 are trapezoidal strips, wider at the top and narrower at the bottom, to prevent clogging when small grapes enter the screens 303. Furthermore, the sieving support platform 301 can be constructed using a combination of a vibrating motor and an eccentric wheel. Vibration causes the supporting platform to vibrate in both vertical and horizontal directions, allowing the grapes to tumble and disperse fully, thus improving the screening effect. The eccentric wheel is connected to a variable frequency motor, and the motor speed can be adjusted by the frequency converter to control the frequency and intensity of vibration, further improving the vibration effect and promoting the screening of grapes. A collection trough 601 is provided below the screen 303 to collect residues and juices, and facilitates centralized cleaning. The sides and bottom of the collection trough 601 are connected to corresponding ball valves for discharging grape juice and dirty water from washing.
