Description

Technical Field

[0001] The present invention relates to the technical field of screening equipment, and particularly relates to an anti-blocking hydraulic screen. Background Art

[0002] Currently, in the fruit processing industry, such as fruit juice production and canned fruit manufacturing, hydraulic screens are often used. Based on the scouring and screening effects of water flow on solid particles, when a liquid containing fruit particles flows through the screen surface, due to the pore size design of the screen mesh, the liquid can flow out through the pores, while the fruit particles are retained on the screen surface. With the continuous scouring of the liquid, the fruit particles on the screen surface gradually gather and roll to the discharge port, thereby achieving solid-liquid separation.

[0003] Most of the cleaning mechanisms in existing hydraulic screens have simple structures. They mostly clean the filter components by setting brushes that reciprocate along the surface of the filter components. However, when the brushes slide upward along the surface of the filter components from bottom to top, the brushes often drive the fruit particles on the surface of the filter components upward and accumulate at the top of the filter components, making it inconvenient for the fruit particles to drain downward along the filter components. And when the brushes slide downward along the surface of the filter components from top to bottom, the accumulated fruit particles will move downward again, thereby increasing the probability of blockage. At the same time, most of the vibration anti-blocking mechanisms are fixedly arranged, which leads to a gradual decrease in the vibration generated at the part of the filter component far from the vibration anti-blocking mechanism. It not only has a poor vibration anti-blocking effect but also easily causes deformation of the filter component. Therefore, in view of the above technical problems, an anti-blocking hydraulic screen is proposed. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention proposes an anti-blocking hydraulic screen, which can avoid affecting the discharge of fruit particles when cleaning the outer surface of the filter plate, reduce the probability of blockage, and at the same time can knock the filter plate along the length direction of the filter plate to generate vibration, improving the vibration anti-blocking effect and avoiding deformation of the filter plate.

[0005] An anti-blocking hydraulic screen includes: a box body and an anti-blocking mechanism. The box body is provided with a water inlet and a water outlet. The bottom end of the water inlet is communicated with the top end of the water outlet, and a filter plate is inclined at the communicating part. The anti-blocking mechanism includes:

[0006] A first brush plate, with a mounting rod provided at the top;

[0007] The driving mechanism includes a mounting block, a guiding component and a driving component. The mounting blocks capable of sliding along the length direction of the filter plate are arranged on both sides of the box body. Both ends of the mounting rod are slidably arranged on the two groups of mounting blocks along the thickness direction of the filter plate. The guiding component connects the box body and the mounting rod and is used to drive the first brush plate to abut against the top surface of the filter plate when the mounting block slides from top to bottom, or drive the first brush plate to separate from the top surface of the filter plate when the mounting block slides from bottom to top. The driving component is arranged on the box body and connected to the mounting block for reciprocating sliding of the mounting block; and

[0008] The vibration mechanism includes a knocking rod and a transmission component. The knocking rod is slidably arranged on the mounting rod along the thickness direction of the filter plate and is located above the side of the first brush plate. When the mounting block slides from top to bottom, the knocking rod can be driven to reciprocate and knock the filter plate through the transmission component.

[0009] The beneficial effects of the above anti-blocking hydraulic screen are as follows:

[0010] 1. The driving component drives the mounting block to reciprocate. When the mounting block slides from top to bottom, the mounting block drives the mounting rod and the first brush plate to slide downwards. At this time, the first brush plate abuts against the top surface of the filter plate. The first brush plate slides downwards to clean the top surface of the filter plate and drives the fruit particles on the top surface of the filter plate to move downwards and be discharged from the filter plate. When the mounting block slides from bottom to top, the mounting block drives the mounting rod and the first brush plate to slide upwards. At the same time, the guiding component drives the mounting rod and the first brush plate to slide so that the first brush plate separates from the top surface of the filter plate. At this time, the first brush plate moving upwards will not drive the fruit particles on the top surface of the filter plate to move upwards, thus cleaning the top surface of the filter plate while avoiding affecting the discharge of fruit particles and reducing the blockage probability.

[0011] 2. When the mounting rod slides downwards, the mounting rod drives the knocking rod to slide downwards. At the same time, the transmission component drives the knocking rod to reciprocate and knock the filter plate, so that the knocking rod knocks the filter plate along the length direction of the filter plate to make it vibrate, improving the vibration anti-blocking effect and avoiding deformation of the filter plate. And the knocking rod is located above the side of the first brush plate, that is, after the first brush plate cleans the top surface of the filter plate, the knocking rod knocks the filter plate, thus ensuring uniform contact between the knocking rod and the filter plate and avoiding the influence of fruit particles on the knocking of the filter plate by the knocking rod.

[0012] In one embodiment, the guiding assembly includes two sets of guiding shafts and a first spring; first guiding grooves and second guiding grooves parallel to the filter plate are formed on both sides of the box body. The top and bottom ends of the first guiding groove and the second guiding groove on the same side are communicated through inclined grooves. The depth of the inclined groove at the top end of the first guiding groove is greater than that of the inclined groove at the top end of the second guiding groove, and the depth of the inclined groove at the bottom end of the first guiding groove is less than that of the inclined groove at the bottom end of the second guiding groove. Mounting holes are formed at both ends of the mounting rod. The opposite ends of the two sets of guiding shafts are slidably mounted in the two sets of mounting holes through the first spring respectively, and the opposite ends of the two sets of guiding shafts are slidably arranged in the two sets of first guiding grooves respectively. When the mounting block drives the mounting rod and the first brush plate to slide downward, the guiding shaft slides downward along the first guiding groove. At this time, the first brush plate abuts against the top surface of the filter plate. When the guiding shaft slides downward into the inclined groove at the bottom end of the first guiding groove, the guiding shaft drives the mounting rod and the first brush plate to move upward under the guiding action of the inclined groove at the bottom end. At this time, the first brush plate is separated from the top surface of the filter plate. When the guiding shaft slides from the inclined groove at the bottom end of the first guiding groove to the inclined groove at the bottom end of the second guiding groove, the guiding shaft abuts against the inclined groove at the bottom end of the second guiding groove under the elastic force of the first spring. At the same time, the mounting block drives the mounting rod and the first brush plate to slide upward. Since the depth of the inclined groove at the bottom end of the first guiding groove is less than that of the inclined groove at the bottom end of the second guiding groove, at this time, the guiding shaft slides along the inclined groove at the bottom end of the second guiding groove into the second guiding groove, so that the first brush plate remains separated from the top surface of the filter plate when sliding upward. When the guiding shaft slides into the inclined groove at the top end of the second guiding groove, the guiding shaft drives the mounting rod and the first brush plate to move downward under the guiding action of the inclined groove at the top end. When the guiding shaft slides from the inclined groove at the top end of the second guiding groove to the inclined groove at the top end of the first guiding groove, the mounting block drives the mounting rod and the first brush plate to slide downward. Since the depth of the inclined groove at the top end of the first guiding groove is greater than that of the inclined groove at the top end of the second guiding groove, at this time, the guiding shaft slides along the inclined groove at the top end of the first guiding groove into the first guiding groove, and the first brush plate abuts against the top surface of the filter plate, which is convenient for driving the first brush plate to slide downward to clean the top surface of the filter plate and driving the first brush plate to slide upward to be separated from the top surface of the filter plate.

[0013] In one embodiment, the driving assembly includes a reciprocating lead screw and a motor; the reciprocating lead screw is rotatably arranged on one side of the box body and is arranged parallel to the filter plate. The reciprocating lead screw is connected to one of the mounting blocks. The rotation of the reciprocating lead screw can drive the mounting block to reciprocate. The motor is arranged on the box body, and the output shaft is connected to the reciprocating lead screw through a coupling. By driving the reciprocating lead screw to rotate through the motor, the mounting block can be driven to reciprocate, which is convenient for driving the mounting block to reciprocate.

[0014] In one embodiment, it also includes a slag discharge mechanism, which includes a spiral guide rod and a bevel gear. A slag discharge groove is provided on the housing, and the slag discharge groove is located at the bottom end of the filter plate. The spiral guide rod is arranged along the width direction of the filter plate and is rotatably arranged in the slag discharge groove. The bevel gear is coaxially arranged at one end of the spiral guide rod and one end of the reciprocating screw rod, and the two sets of bevel gears are meshed. When the fruit particles move downward along the filter plate and are discharged from the filter plate, the fruit particles will fall into the slag discharge groove. At the same time, the reciprocating screw rod rotates through the two sets of bevel gears to drive the spiral guide rod to rotate. The spiral guide rod rotates to push the fruit particles in the slag discharge groove out of the device from one side of the slag discharge groove, thereby facilitating the collection of the filtered fruit particles and the recycling of the fruit particles. The rotation of the spiral guide rod does not require additional power equipment, which saves energy and reduces the use cost of the device.

[0015] In one embodiment, the bottom side of the slag discharge groove is provided with a plurality of groups of water leakage holes connected with the water outlet. By providing the water leakage holes, when the spiral guide rod rotates to push the fruit particles to move along the slag discharge groove, the water attached to the fruit particles can flow into the water outlet through the water leakage holes, thereby further improving the solid-liquid separation effect.

[0016] In one embodiment, the transmission assembly includes a wedge-shaped groove, a fixed rod is provided at the top of the knocking rod, and a plurality of fixed shafts are provided at the top of the fixed rod. The plurality of fixed shafts can be slidably arranged on the mounting rod along the thickness direction of the filter plate, and shift shafts are provided at both ends of the fixed rod. A plurality of wedge-shaped grooves are provided on both sides of the box body along the length direction of the filter plate. The mounting block slides from top to bottom to make the shift shafts slide along the plurality of wedge-shaped grooves, and the mounting block slides from bottom to top to separate the shift shafts from the plurality of wedge-shaped grooves. The mounting block slides from top to bottom, driving the fixing rod and the knocking rod to slide downward. When the fixing rod slides downward and causes the dial shaft to fall into the bottom end of the wedge-shaped groove, the fixing rod and the knocking rod move downward due to gravity. At this time, the knocking rod can knock the filter plate. As the fixing rod continues to move downward, the dial shaft slides along the inclined surface of the wedge-shaped groove. At this time, the dial shaft drives the dial shaft under the guidance of the inclined surface of the wedge-shaped groove to drive the fixing rod and the knocking rod to move upward. At this time, the knocking rod is separated from the filter plate. When the dial shaft moves downward to the next set of wedge grooves, the fixing rod and the knocking rod are again pulled downward by gravity. The filter plate can be knocked repeatedly along the length direction of the filter plate, and it is convenient to knock the filter plate along the length direction of the filter plate, and when the mounting block slides from bottom to top, the mounting rod moves upward to drive the fixing rod and the knocking rod to move upward. At this time, the dial shaft is separated from the wedge-shaped groove, so that the knocking rod remains separated from the filter plate, and then when the mounting block slides from bottom to top, the knocking rod will not knock the filter plate, thereby preventing the knocking rod from affecting the discharge of fruit particles and knocking on the fruit particles to cause uneven force on the filter plate.

[0017] In one embodiment, the transmission assembly further includes a second spring; the second spring is sleeved on multiple groups of the fixed shafts, and two ends of multiple groups of the second springs respectively abut against the mounting rod and the fixed rod. By arranging the second spring to apply pressure to the fixed rod, it can be ensured that when the mounting block slides from top to bottom, the shifting shaft always slides along multiple groups of wedge-shaped grooves, thereby ensuring the stability of the knocking rod knocking the filter plate along the length direction of the filter plate. Moreover, when the shifting shaft slides from one group of wedge-shaped grooves into the next group of wedge-shaped grooves, the reaction force of the second spring can enhance the force of the knocking rod knocking the filter plate, thereby enhancing the vibration of the filter plate and further improving the vibration anti-blocking effect.

[0018] In one embodiment, the vibration mechanism further includes a dredging assembly, which is arranged on the knocking rod and is used for dredging the holes of the filter plate when the knocking rod knocks the filter plate.

[0019] In one embodiment, the dredging assembly includes a second brush plate; an installation groove is formed at the bottom end of the knocking rod, the second brush plate is arranged in the installation groove, and the brush part at the bottom end of the second brush plate protrudes from the bottom end of the knocking rod. When the knocking rod knocks the filter plate, the knocking rod can drive the second brush plate to contact the filter plate. At this time, the brush part of the second brush plate can penetrate into the holes of the filter plate to clean the holes, thereby preventing fine fruit particles from adhering to the holes of the filter plate and preventing the filtration efficiency of the filter plate from decreasing.

[0020] In one embodiment, the dredging assembly further includes a third spring, and the top end of the second brush plate is slidably arranged in the installation groove through multiple groups of the third springs. By arranging the third spring, when the brush part of the second brush plate cannot penetrate into the holes of the filter plate, after the knocking rod drives the second brush plate to contact the filter plate, the second brush plate stops moving and compresses the third spring. At this time, the knocking rod can continue to move to knock the filter plate and retract the second brush plate into the installation groove, thereby avoiding damage to the second brush plate and ensuring that the knocking rod can knock the filter plate to make it vibrate.

[0037] Hereinafter, embodiments of the technical solutions of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0038] Please refer to Figures 1 to 4 , a clog - proof hydraulic screen in an embodiment, includes a box body 10 and a clog - proof mechanism. The box body 10 is provided with a water inlet 101 and a drain outlet 102. The bottom end of the water inlet 101 is communicated with the top end of the drain outlet 102, and a filter plate 103 is inclinedly arranged at the communicating part. The clog - proof mechanism includes a first brush plate 20, a driving mechanism and a vibration mechanism.

[0039] Among them, an installation rod 201 is arranged at the top end of the first brush plate 20. The driving mechanism includes an installation block 30, a guiding component and a driving component. Installation blocks 30 capable of sliding along the length direction of the filter plate 103 are arranged on both sides of the box body 10. Both ends of the installation rod 201 are slidably arranged on the two groups of installation blocks 30 along the thickness direction of the filter plate 103. The guiding component connects the box body 10 and the installation rod 201, and is used to drive the first brush plate 20 to abut against the top surface of the filter plate 103 when the installation block 30 slides from top to bottom, or drive the first brush plate 20 to separate from the top surface of the filter plate 103 when the installation block 30 slides from bottom to top. The driving component is arranged on the box body 10 and is connected to the installation block 30 for reciprocating sliding of the installation block 30. The vibration mechanism includes a knocking rod 40 and a transmission component. The knocking rod 40 is slidably arranged on the installation rod 201 along the thickness direction of the filter plate 103 and is located above the side of the first brush plate 20. When the installation block 30 slides from top to bottom, it can drive the knocking rod 40 to reciprocate and knock the filter plate 103 through the transmission component.

[0040] In the above embodiments, the driving component drives the mounting block 30 to slide reciprocally. When the mounting block 30 slides downward from top to bottom, the mounting block 30 drives the mounting rod 201 and the first brush plate 20 to slide downward. At this time, the first brush plate 20 abuts against the top surface of the filter plate 103. The first brush plate 20 slides downward to clean the top surface of the filter plate 103 and drives the fruit particles on the top surface of the filter plate 103 to move downward and discharge from the filter plate 103. When the mounting block 30 slides upward from bottom to top, the mounting block 30 drives the mounting rod 201 and the first brush plate 20 to slide upward. At the same time, the guiding component drives the mounting rod 201 and the first brush plate 20 to slide so that the first brush plate 20 is separated from the top surface of the filter plate 103. At this time, the first brush plate 20 moving upward will not drive the fruit particles on the top surface of the filter plate 103 to move upward. Thus, while cleaning the top surface of the filter plate 103, the discharge of fruit particles is not affected, the blockage probability is reduced. And when the mounting rod 201 slides downward, the mounting rod 201 drives the knocking rod 40 to slide downward. At the same time, the transmission component drives the knocking rod 40 to slide reciprocally to knock the filter plate 103, so that the knocking rod 40 knocks the filter plate 103 along the length direction of the filter plate 103 to make it vibrate, improving the vibration anti-blocking effect and avoiding deformation of the filter plate 103. And the knocking rod 40 is located above the side of the first brush plate 20, that is, after the first brush plate 20 cleans the top surface of the filter plate 103, the knocking rod 40 knocks the filter plate 103, thus ensuring uniform contact between the knocking rod 40 and the filter plate 103 and avoiding the influence of fruit particles on the knocking of the filter plate 103 by the knocking rod 40.

[0041] Specifically in the above embodiments, first limiting grooves 105 are formed on both sides of the box body 10. One ends of two groups of mounting blocks 30 are respectively provided with first limiting blocks 308. The two groups of first limiting blocks 308 can be slidably arranged in the two groups of first limiting grooves 105 along the length direction of the filter plate 103. Second limiting grooves 309 are formed on the opposite sides of the two groups of mounting blocks 30. Both ends of the mounting rod 201 are provided with second limiting blocks 203. The two groups of second limiting blocks 203 can be slidably arranged in the two groups of second limiting grooves 309 along the thickness direction of the filter plate 103.

[0042] Please refer to Figure 1 、 Figure 2 、 Figures 4 to 7, in one embodiment, the guiding assembly includes two groups of guiding shafts 301 and a first spring 302; both sides of the box body 10 are provided with a first guiding groove 303 and a second guiding groove 304 parallel to the filter plate 103. The top and bottom ends of the first guiding groove 303 and the second guiding groove 304 on the same side are connected through an inclined groove 305. The depth of the inclined groove 305 at the top end of the first guiding groove 303 is greater than the depth of the inclined groove 305 at the top end of the second guiding groove 304, and the depth of the inclined groove 305 at the bottom end of the first guiding groove 303 is less than the depth of the inclined groove 305 at the bottom end of the second guiding groove 304. Installation holes 202 are provided at both ends of the installation rod 201. The opposite ends of the two groups of guiding shafts 301 are respectively slidably installed in the two installation holes 202 through the first spring 302, and the opposite ends of the two groups of guiding shafts 301 are respectively slidably arranged in the two first guiding grooves 303.

[0043] In the above embodiment, when the installation block 30 drives the installation rod 201 and the first brush plate 20 to slide downward, the guiding shaft 301 slides downward along the first guiding groove 303. At this time, the first brush plate 20 abuts against the top surface of the filter plate 103. When the guiding shaft 301 slides downward into the inclined groove 305 at the bottom end of the first guiding groove 303, the guiding shaft 301 drives the installation rod 201 and the first brush plate 20 to move upward under the guiding action of the inclined groove 305 at the bottom end. At this time, the first brush plate 20 is separated from the top surface of the filter plate 103. When the guiding shaft 301 slides from the inclined groove 305 at the bottom end of the first guiding groove 303 to the inclined groove 305 at the bottom end of the second guiding groove 304, the guiding shaft 301 abuts against the inclined groove 305 at the bottom end of the second guiding groove 304 under the elastic force of the first spring 302. At the same time, the installation block 30 drives the installation rod 201 and the first brush plate 20 to slide upward. Since the depth of the inclined groove 305 at the bottom end of the first guiding groove 303 is less than the depth of the inclined groove 305 at the bottom end of the second guiding groove 304, at this time, the guiding shaft 301 slides along the inclined groove 305 at the bottom end of the second guiding groove 304 into the second guiding groove 304, so as to keep the first brush plate 20 separated from the top surface of the filter plate 103 when the first brush plate 20 slides upward. When the guiding shaft 301 slides into the inclined groove 305 at the top end of the second guiding groove 304, the guiding shaft 301 drives the installation rod 201 and the first brush plate 20 to move downward under the guiding action of the inclined groove 305 at the top end. When the guiding shaft 301 slides from the inclined groove 305 at the top end of the second guiding groove 304 to the inclined groove 305 at the top end of the first guiding groove 303, the installation block 30 drives the installation rod 201 and the first brush plate 20 to slide downward. Since the depth of the inclined groove 305 at the top end of the first guiding groove 303 is greater than the depth of the inclined groove 305 at the top end of the second guiding groove 304, at this time, the guiding shaft 301 slides along the inclined groove 305 at the top end of the first guiding groove 303 into the first guiding groove 303, and makes the first brush plate 20 abut against the top surface of the filter plate 103, which is convenient for driving the first brush plate 20 to slide downward to clean the top surface of the filter plate 103 and for the first brush plate 20 to slide upward and be separated from the top surface of the filter plate 103.

[0044] Please refer to Figure 2 and Figure 4 In one embodiment, the driving assembly includes a reciprocating lead screw 306 and a motor 307; the reciprocating lead screw 306 is rotatably arranged on one side of the box body 10 and is arranged in parallel with the filter plate 103. The reciprocating lead screw 306 is connected to one group of mounting blocks 30. The rotation of the reciprocating lead screw 306 can drive the mounting blocks 30 to reciprocate. The motor 307 is arranged on the box body 10, and the output shaft is connected to the reciprocating lead screw 306 through a coupling.

[0045] In the above embodiment, by driving the reciprocating lead screw 306 to rotate through the motor 307, the mounting blocks 30 can be driven to reciprocate, and it is convenient to drive the mounting blocks 30 to reciprocate.

[0046] Please refer to Figures 1 to 3 In one embodiment, it further includes a slag discharging mechanism. The slag discharging mechanism includes a spiral guide rod 50 and bevel gears 501. A slag discharging groove 104 is formed on the box body 10. The slag discharging groove 104 is located at the bottom end of the filter plate 103. The spiral guide rod 50 is arranged along the width direction of the filter plate 103 and is rotatably arranged in the slag discharging groove 104. One end of the spiral guide rod 50 and one end of the reciprocating lead screw 306 are both coaxially provided with bevel gears 501, and the two groups of bevel gears 501 are meshed with each other.

[0047] In the above embodiment, when the fruit particles move downward along the filter plate 103 and are discharged from the filter plate 103, the fruit particles will fall into the slag discharging groove 104. At the same time, the rotation of the reciprocating lead screw 306 drives the spiral guide rod 50 to rotate through the cooperation of the two groups of bevel gears 501. The rotation of the spiral guide rod 50 can push the fruit particles in the slag discharging groove 104 out of the device from one side of the slag discharging groove 104, so as to facilitate the collection of the filtered fruit particles, facilitate the recycling of the fruit particles, and the rotation of the spiral guide rod 50 does not require additional power equipment, saving energy and reducing the use cost of the device.

[0048] On the basis of the above embodiment, further, a plurality of water leakage holes 1041 communicating with the drain port 102 are formed on the bottom side of the slag discharging groove 104. By providing the water leakage holes 1041, when the spiral guide rod 50 rotates to push the fruit particles to move along the slag discharging groove 104, the water attached to the fruit particles can flow into the drain port 102 through the water leakage holes 1041, thereby further improving the solid-liquid separation effect.

[0049] Please refer to Figure 1 、 Figure 8 and Figure 9In one embodiment, the transmission assembly includes a wedge-shaped groove 403, a fixed rod 401 is arranged at the top of the knocking rod 40, and multiple groups of fixed shafts 4011 are arranged at the top of the fixed rod 401. The multiple groups of fixed shafts 4011 can be slidably arranged on the mounting rod 201 along the thickness direction of the filter plate 103. A shifting shaft 402 is arranged at both ends of the fixed rod 401. Multiple groups of wedge-shaped grooves 403 are opened on both sides of the box body 10 along the length direction of the filter plate 103. The mounting block 30 slides from top to bottom to make the shifting shaft 402 slide along the multiple groups of wedge grooves 403, and the mounting block 30 slides from bottom to top to separate the shifting shaft 402 from the multiple groups of wedge grooves 403.

[0050] In the above embodiment, the mounting block 30 slides from top to bottom, driving the fixing rod 401 and the knocking rod 40 to slide downward. When the fixing rod 401 slides downward to make the dial shaft 402 fall into the bottom end of the wedge-shaped groove 403, the fixing rod 401 and the knocking rod 40 move downward due to gravity. At this time, the knocking rod 40 can knock the filter plate 103. As the fixing rod 401 continues to move downward, the dial shaft 402 slides along the inclined surface of the wedge-shaped groove 403. At this time, the dial shaft 402 is driven by the inclined surface of the wedge-shaped groove 403 to drive the fixing rod 401 and the knocking rod 40 to move upward. At this time, the knocking rod 40 is separated from the filter plate 103. When the dial shaft 402 moves downward to the next set of wedge-shaped grooves 403, the fixing rod 401 and the knocking rod 40 are moved downward by gravity. 01 and the knocking rod 40 move downward again due to gravity to knock the filter plate 103, and this can be repeated to knock the filter plate 103 along the length direction of the filter plate 103. It is convenient to knock the filter plate 103 along the length direction of the filter plate 103, and when the mounting block 30 slides from bottom to top, the mounting rod 201 moves upward to drive the fixing rod 401 and the knocking rod 40 to move upward. At this time, the dial shaft 402 is separated from the wedge-shaped groove 403, so that the knocking rod 40 remains separated from the filter plate 103, and then when the mounting block 30 slides from bottom to top, the knocking rod 40 will not knock the filter plate 103, thereby avoiding the knocking rod 40 affecting the discharge of fruit particles and knocking on the fruit particles to cause uneven force on the filter plate 103.

[0051] On the basis of the above embodiment, the transmission assembly further includes a second spring 404; the second spring 404 is sleeved on the multiple groups of fixed shafts 4011, and the two ends of the multiple groups of second springs 404 respectively resist the mounting rod 201 and the fixed rod 401. By setting the second spring 404 to apply pressure to the fixed rod 401, it can be ensured that when the mounting block 30 slides from top to bottom, the dial shaft 402 always slides along the multiple groups of wedge-shaped grooves 403, thereby ensuring the stability of the knocking rod 40 knocking the filter plate 103 along the length direction of the filter plate 103, and when the dial shaft slides from one group of wedge-shaped grooves 403 of 402 into the next group of wedge-shaped grooves 403, the reaction force of the second spring 404 can increase the force of the knocking rod 40 knocking the filter plate 103, thereby enhancing the vibration of the filter plate 103, and further improving the vibration blocking effect.

[0052] Please refer to Figure 1 、 Figure 4 and Figure 8 In one embodiment, the vibration mechanism further includes a dredging component disposed on the knocking rod 40 for dredging the holes of the filter plate 103 when the knocking rod 40 knocks the filter plate 103. Specifically, the dredging component includes a second brush plate 405; an installation groove 406 is formed at the bottom end of the knocking rod 40, the second brush plate 405 is disposed in the installation groove 406, and the brush part at the bottom end of the second brush plate 405 protrudes from the bottom end of the knocking rod 40.

[0053] In the above embodiment, when the knocking rod 40 knocks the filter plate 103, the knocking rod 40 can drive the second brush plate 405 to contact the filter plate 103. At this time, the brush part of the second brush plate 405 can penetrate into the holes of the filter plate 103 to clean the holes, thereby preventing small fruit particles from adhering to the holes of the filter plate 103 and preventing the filtration efficiency of the filter plate 103 from decreasing.

[0054] Based on the above embodiment, further, the dredging component further includes a third spring 407, and the top end of the second brush plate 405 is slidably disposed in the installation groove 406 through a plurality of groups of third springs 407. By providing the third spring 407, when the brush part of the second brush plate 405 cannot penetrate into the holes of the filter plate 103, after the knocking rod 40 drives the second brush plate 405 to contact the filter plate 103, the second brush plate 405 stops moving and compresses the third spring 407. At this time, the knocking rod 40 can continue to move to knock the filter plate 103 and retract the second brush plate 405 into the installation groove 406, thereby avoiding damage to the second brush plate 405 while ensuring that the knocking rod 40 can knock the filter plate 103 to make it vibrate.

[0055] The specific implementation manner of the above anti-blocking hydraulic sieve is as follows:

[0056] By starting the motor 307 to drive the reciprocating lead screw 306 to rotate to drive the mounting block 30 to reciprocate. When the mounting block 30 slides from top to bottom, the mounting block 30 drives the mounting rod 201 and the first brush plate 20 to slide downward. At this time, the first brush plate 20 abuts against the top surface of the filter plate 103, the guide shaft 301 slides downward along the first guide groove 303, and the first brush plate 20 slides downward to clean the top surface of the filter plate 103 and drive the fruit particles on the top surface of the filter plate 103 to move downward and discharge from the filter plate 103.

[0057] When the guide shaft 301 slides downward into the inclined slot 305 at the bottom end of the first guide slot 303, the guide shaft 301 drives the mounting rod 201 and the first brush plate 20 to move upward under the guiding action of the inclined slot 305 at the bottom end. At this time, the first brush plate 20 is separated from the top surface of the filter plate 103. When the guide shaft 301 slides from the inclined slot 305 at the bottom end of the first guide slot 303 into the inclined slot 305 at the bottom end of the second guide slot 304, the guide shaft 301 abuts against the inclined slot 305 at the bottom end of the second guide slot 304 under the elastic force of the first spring 302. At the same time, the mounting block 30 drives the mounting rod 201 and the first brush plate 20 to slide upward. Since the depth of the inclined slot 305 at the bottom end of the first guide slot 303 is less than the depth of the inclined slot 305 at the bottom end of the second guide slot 304, at this time, the guide shaft 301 slides along the inclined slot 305 at the bottom end of the second guide slot 304 into the second guide slot 304, so that when the first brush plate 20 slides upward, it remains separated from the top surface of the filter plate 103. At this time, the upward movement of the first brush plate 20 will not drive the fruit particles on the top surface of the filter plate 103 to move upward, so that while cleaning the top surface of the filter plate 103, the discharge of fruit particles is not affected, and the blockage probability is reduced. When the guide shaft 301 slides into the inclined slot 305 at the top end of the second guide slot 304, the guide shaft 301 drives the mounting rod 201 and the first brush plate 20 to move downward under the guiding action of the inclined slot 305 at the top end. When the guide shaft 301 slides from the inclined slot 305 at the top end of the second guide slot 304 into the inclined slot 305 at the top end of the first guide slot 303, the mounting block 30 drives the mounting rod 201 and the first brush plate 20 to slide downward. Since the depth of the inclined slot 305 at the top end of the first guide slot 303 is greater than the depth of the inclined slot 305 at the top end of the second guide slot 304, at this time, the guide shaft 301 slides along the inclined slot 305 at the top end of the first guide slot 303 into the first guide slot 303, and the first brush plate 20 abuts against the top surface of the filter plate 103. Repeating this way can repeatedly clean the top surface of the filter plate 103.

[0058] Meanwhile, the installation block 30 slides downward to drive the fixing rod 401 and the knocking rod 40 to slide downward. When the fixing rod 401 slides downward and the shifting shaft 402 falls to the bottom end of the wedge-shaped groove 403, the reaction force of the second spring 404 causes the fixing rod 401 and the knocking rod 40 to move downward to knock the filter plate 103. As the fixing rod 401 continues to move downward, the shifting shaft 402 slides along the inclined surface of the wedge-shaped groove 403. At this time, under the guiding action of the inclined surface of the wedge-shaped groove 403, the shifting shaft 402 drives the shifting shaft 402 to drive the fixing rod 401 and the knocking rod 40 to move upward and compress the second spring 404. At this time, the knocking rod 40 is separated from the filter plate 103. When the shifting shaft 402 moves downward into the next group of wedge-shaped grooves 403, the reaction force of the second spring 404 causes the fixing rod 401 and the knocking rod 40 to move downward again to knock the filter plate 103. Repeating like this can knock the filter plate 103 along the length direction of the filter plate 103 to make it vibrate, improving the vibration anti-blocking effect, avoiding deformation of the filter plate 103, and the knocking rod 40 is located above the side of the first brush plate 20, that is, after the first brush plate 20 cleans the top surface of the filter plate 103, the knocking rod 40 knocks the filter plate 103, so as to ensure uniform contact between the knocking rod 40 and the filter plate 103, further improving the uniformity of the vibration generated by the filter plate 103 under force. And when the installation block 30 slides upward from bottom to top, the installation rod 201 moves upward to drive the fixing rod 401 and the knocking rod 40 to move upward. At this time, the shifting shaft 402 is separated from the wedge-shaped groove 403, so that the knocking rod 40 remains separated from the filter plate 103. Furthermore, when the installation block 30 slides upward from bottom to top, the knocking rod 40 does not knock the filter plate 103, avoiding the influence of the knocking rod 40 on the discharge of fruit particles and the uneven force on the filter plate 103 caused by knocking on the fruit particles.
