Abstract
Description
Technical Field
[0001] This utility model relates to the field of brewing equipment technology, and specifically provides a screening device. Background Technology
[0002] In the early stages of winemaking, grapes need to be processed. One such process is separating the stems from the berries to prevent the stems from fermenting with the berries and affecting the wine's quality. This separation is typically achieved using a screening device. This device uses a vibrating screen with perforated openings. The stems fall through the openings, while the berries are conveyed downstream by the vibration of the screen, thus completing the separation process.
[0003] However, when separating the stems from the grapes, the stems themselves have many branches, which makes them easy to get stuck in the sieve holes and block them. As the number of blocked sieve holes gradually increases, the sieve holes can no longer let the stems fall through, causing the stems to follow the grapes into the downstream processes, thus mixing the stems with the grapes and affecting the quality of the wine. Utility Model Content
[0004] This invention provides a screening device to solve the problem that fruit stems easily get stuck in the sieve holes and clog the sieve holes, preventing subsequent fruit stems from falling through the sieve holes, thus preventing the fruit stems from separating from the fruit and affecting the quality of the wine.
[0005] The technical solution of this utility model is as follows:
[0006] A screening device includes a vibrating screen and a cleaning mechanism. The vibrating screen is provided with screen holes, and the cleaning mechanism is disposed on the lower side of the vibrating screen. The cleaning mechanism includes a movable part and flexible bristles. The bristles are disposed on the movable part and the movable part is movably connected to the vibrating screen. One end of the bristles is connected to the movable part, and the other end of the bristles is provided with a flexible hook.
[0007] In this design, the brush bristles apply force from below to the fruit stems clogging the sieve holes through a reciprocating brushing motion. This prevents the stems from remaining stable within the sieve holes, causing them to fall out and preventing further blockage. Because the ends of the brush bristles are equipped with hooks, and both the bristles and hooks are flexible, they can enter the sieve holes during the movement of the moving part. The hooks can then catch the fruit stems. As the moving part continues to move and the brush bristles move out of the sieve holes, the hooks can pull the fruit stems out, thus resolving the sieve hole blockage problem.
[0008] In a preferred embodiment, the moving part includes a slider, which is slidably connected to the vibrating screen.
[0009] In this design, a slider is slidably connected to the vibrating screen, allowing the brush bristles to reciprocate relative to the vibrating screen.
[0010] Preferably, the moving part further includes a roller, the two ends of which are rotatably connected to the slider, and the bristles are disposed on the side of the roller.
[0011] In this design, a rotatable roller is installed, and the bristles are placed on the side of the roller. The roller rotates when the slider moves, which can improve the contact efficiency between the bristles and the sieve holes, thereby improving the cleaning efficiency of the fruit stems inside the sieve holes.
[0012] Preferably, the bristles are distributed along the axial direction and circumferential direction of the roller.
[0013] In this design, bristles are arranged on the side of the roller along both the axial and circumferential directions, which can improve the coverage of the bristles.
[0014] Preferably, the hook is oriented in the rolling direction of the roller.
[0015] In this design, the hook faces the direction of the roller's rotation, while the bristles move in the same direction. Therefore, as the hook moves with the bristles, it will actively hook onto the fruit stalk inside the sieve holes, thereby hooking the fruit stalk out of the sieve holes.
[0016] Preferably, the cleaning mechanism further includes a cleaning comb, which has a plurality of teeth, one end of which is inserted between the bristles.
[0017] In this solution, a cleaning comb is provided to remove fruit stems stuck between the bristles, preventing the bristles from continuing to carry the fruit stems out of the sieve holes.
[0018] Preferably, the cleaning comb includes a comb back, one end of the comb teeth is connected to the comb back, and the comb back is fixedly connected to the slider.
[0019] In this solution, connecting the comb back to the slider ensures that the straight-line distance between the cleaning comb and the roller remains constant, thus ensuring that the cleaning comb can clean the fruit stems between the bristles in real time.
[0020] Preferably, the ends of the comb teeth abut against the side of the roller, and the comb teeth are tangential or inclined relative to the side of the roller.
[0021] In this design, the comb teeth are tangent or inclined to the side of the roller, so that when the comb teeth comb the fruit stems between the bristles, the side of the comb teeth closer to the roller will contact the fruit stems first, thereby giving the fruit stems a force to move away from the roller and causing the fruit stems to detach from the bristles.
[0022] Preferably, the slider is equipped with a power motor, which is connected to the roller drive and is used to drive the roller to rotate.
[0023] In this design, the power motor is mounted on the slider, allowing it to move along with the slider. This ensures that the power motor and the roller maintain a constant transmission relationship, thereby ensuring that the roller can rotate continuously as the slider moves.
[0024] Preferably, the vibrating screen is provided with a telescopic mechanism, which is connected to the slider and is used to drive the slider to move back and forth.
[0025] In this design, a telescopic mechanism is provided to push the slider relative to the vibrating screen, thereby enabling the cleaning mechanism to act on several screen holes on the vibrating screen.
[0026] The beneficial effects of this utility model are:
[0027] This invention uses brush bristles and hooks at the ends of the bristles to clean the fruit stems that clog the sieve holes, thereby eliminating the problem of fruit stems clogging the sieve holes and preventing the fruit stems from being unable to separate from the fruit due to sieve blockage.

[0038] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.
[0039] Example 1:
[0040] like Figure 1 As shown, this embodiment provides a screening device, including a vibrating screen 1 and a cleaning mechanism. The vibrating screen 1 is provided with screen holes 2 for screening fruit granules and stems. The cleaning mechanism is disposed on the vibrating screen 1 and includes a moving part and brush bristles 4, which are made of flexible plastic. Figure 2 As shown, a hook 10 is provided at the end of the brush bristles 4. The hook 10 is integrally formed with the brush bristles 4, therefore, the hook 10 is essentially made of flexible plastic and is flexible and deformable. One end of the brush bristles 4 is connected to the moving part, and the hook 10 is located at the end of the brush bristles 4 away from the moving part. The moving part is slidably connected to the vibrating screen 1 and is used to drive the brush bristles 4 to move relative to the vibrating screen 1. When the moving part moves relative to the vibrating screen 1, the brush bristles 4 will enter or exit the screen holes 2 on the vibrating screen 1. If there are fruit stems blocking the screen holes 2, the brush bristles 4 will exert a force on the fruit stems in the screen holes 2 when entering or exiting the screen holes 2, causing the fruit stems to move and thus allowing the fruit stems to detach from the screen holes 2, preventing the screen holes 2 from being blocked by fruit stems. Furthermore, after the bristles 4 enter the sieve hole 2, during the contact between the hook 10 and the fruit stem, the hook 10 will hook onto the fruit stem. As the moving part continues to move, the bristles 4 will move out of the sieve hole 2. At this time, the hook 10 will follow the bristles 4 out of the sieve hole 2 and simultaneously hook the hooked fruit stem out of the sieve hole 2, thus solving the problem of the sieve hole 2 being blocked by the fruit stem.
[0041] like Figure 3 As shown, because the bristles 4 are flexible, when the bristles 4, which do not correspond to the position of the screen holes 2, come into contact with the bottom surface of the vibrating screen 1, the bristles 4 will bend without affecting the rotation of the drum 3.
[0042] The function of the moving part is to move the position of the brush bristles 4. The moving part includes a slider and a roller 3. The two ends of the roller 3 are rotatably connected to the slider, and the slider is slidably connected to the vibrating screen 1.
[0043] The number of sliders can be two, or only one slider can be set.
[0044] When two sliders are provided, the two sliders are slidably connected to both sides of the vibrating screen 1, and the two ends of the drum 3 are rotatably connected to the two sliders respectively.
[0045] like Figure 5 As shown, when only one slider is set, the slider is provided with two supports that are rotatably connected to the roller 3, and the two ends of the roller 3 are respectively rotatably connected to the two supports.
[0046] Guide rails 9 can be respectively installed on both sides of the bottom of the vibrating screen 1. The guide rails 9 are fixedly connected to the vibrating screen 1 by welding or fasteners. The slider is provided with a sliding groove 13 adapted to the guide rail 9, and the sliding groove 13 allows the slider to slide on the guide rail 9. The shape of the sliding groove 13 can be a dovetail groove, and the cross-sectional shape of the guide rail 9 is adapted to the shape of the dovetail groove. The dovetail groove can prevent the slider from detaching from the guide rail 9.
[0047] The slider can reciprocate linearly along the bottom surface of the vibrating screen 1. To achieve this reciprocating movement, a cylinder can be installed on the bottom surface of the vibrating screen 1. One end of the cylinder is connected to the vibrating screen 1, and the other end is connected to the slider. The reciprocating movement of the slider is controlled by extending or retracting the cylinder through an air pump. The cylinder and the air pump are connected via an air supply pipe, and a valve is installed on the air supply pipe. One cylinder can be connected to two air supply pipes simultaneously, located on either side of the piston of the cylinder. The extension or retraction of the cylinder is controlled by the valve controlling the air intake direction. The cylinder thus serves as a telescopic mechanism for controlling the movement of the slider.
[0048] Similarly, a lead screw 85 and nut 12 mechanism can be installed at the bottom of the vibrating screen 1. This mechanism includes a lead screw 85 and a nut 12. Both ends of the lead screw 85 are rotatably connected to the base of the vibrating screen 1. The nut 12 is driven by the lead screw 85 and connected to the slider. A motor 7 is installed at the bottom of the vibrating screen 1 to drive the lead screw 85 to rotate. The output shaft of the motor 7 is driven by the lead screw 85 to drive its rotation. When the lead screw 85 rotates, the nut 12 moves along the axis of the lead screw 85, thereby moving the slider.
[0049] A seated bearing 6 can be installed at the bottom of the vibrating screen 1. The seated bearing 6 is fixedly connected to the vibrating screen 1 by fasteners, and the lead screw 85 is connected to the seated bearing 6.
[0050] The slider is also equipped with a power motor 11 for driving the roller 3 to rotate. The power motor 11 is fixedly connected to the slider, and the output shaft of the power motor 11 is connected to the roller 3 for transmission. The power motor 11 is used to drive the roller 3 to rotate. The power motor 11 starts to work after being powered on. The power motor 11 is equipped with a power cord with a plug. After the plug is inserted into the socket, it supplies power to the power motor 11, causing the power motor 11 to start rotating.
[0051] The output shaft of the power motor 11 and the roller 3 can be connected by a coupling or by gears.
[0052] The bristles 4 are positioned on the side of the roller 3, and are arranged along the axial and circumferential directions of the roller 3, so that the bristles 4 can be evenly distributed on the roller 3. When the roller 3 is driven to rotate by the power motor 11, the contact efficiency between the bristles 4 and the screen holes 2 of the vibrating screen 1 can be improved, thereby improving the contact efficiency between the bristles 4 and the fruit stems in the screen holes 2, and thus improving the cleaning effect of the bristles 4 on the fruit stems in the screen holes 2.
[0053] like Figure 4 As shown, the vibrating screen 1 is provided with several screen holes 2. The screen holes 2 are strip-shaped holes. The length direction of the strip-shaped holes is parallel to the movement direction of the fruit and perpendicular to the axis of the roller 3, so that the bristles 4 can enter the screen holes 2 more smoothly, thereby hooking out the fruit stalks in the screen holes 2.
[0054] Example 2:
[0055] This second embodiment provides a screening device. Unlike the first embodiment, the cleaning mechanism of this second embodiment also includes a cleaning comb 14.
[0056] like Figure 6 and Figure 7 As shown, the cleaning comb 14 is designed to remove fruit stems stuck between the bristles 4. When the bristles 4 remove fruit stems from the sieve holes 2, some stems may become stuck between the bristles 4. When fruit stems are stuck between the bristles 4, they obstruct the hooks 10 at the ends of the bristles 4, preventing the hooks 10 from contacting the fruit stems inside the sieve holes 2. The cleaning comb 14 removes the fruit stems between the bristles 4, thus solving the problem of fruit stems obstructing the hooks 10 on the bristles 4.
[0057] The cleaning comb 14 includes a comb back 142 and comb teeth 141. The comb back 142 is fixedly connected to the slider, and several comb teeth 141 are provided on the comb back 142. One end of the comb teeth 141 is connected to the comb back 142, and the other end of the comb teeth 141 abuts against the roller 3. The cleaning comb 14 is located on one side of the roller 3, below the vibrating screen 1, and downstream of the roller 3 in the rolling direction. After the bristles 4 exit from the screen hole 2, some fruit stems will fall directly downwards, while other fruit stems will be stuck between the bristles 4. When the bristles 4 are at the lowest point of the roller 3, if the fruit stems between the bristles 4 have not fallen, these fruit stems are cleaned by the cleaning comb 14. After the fruit stems pass the lowest point of the roller 3, the roller 3 continues to roll, causing the fruit stems to move upwards and then contact the comb teeth 141. The comb teeth 141 will exert a downward force on the fruit stems, combing them off between the bristles 4 as if they were being combed down, thus cleaning the fruit stems.
[0058] The comb teeth 141 are inclined downwards, and the comb teeth 141 are inclined or tangential to the contact point with the roller 3.
