Description

Technical Field

[0001] This utility model relates to the field of crushed stone screening technology, and in particular to a stone vibration screening device. Background Technology

[0002] Crushed stone refers to the process where stone material is evenly fed into a primary crusher by a feeder for initial crushing. The resulting coarse material is then conveyed by a belt conveyor to an impact crusher for further crushing. The finely crushed stone is then fed into a vibrating screen to separate stones of different sizes. Stones that do not meet the size requirements are returned to the impact crusher for further crushing. Large stones are evenly fed into a jaw crusher from a hopper by a vibrating feeder for primary crushing. The coarsely crushed stone is then conveyed by a belt conveyor to an impact crusher for further crushing. The finely crushed stone is then conveyed by a belt conveyor to a screening device for sieving, removing stones that do not meet the size requirements.

[0003] Chinese Patent No. CN216225221U discloses a stone vibration screening device, including a support, a conveyor, a frame, a rod screen, buffer springs, a hopper, side plates, and a vibrating motor. The conveyor is installed at an angle on the support, and the bottom end of the frame is connected to the conveyor frame through multiple sets of buffer springs. The rod screen is installed inside the frame, and side plates are installed on both sides of the top of the frame. In this screening device for crushed stone production, the stone enters the rod screen through the hopper. Qualified stone falls through the gaps, while unqualified stone slides off the rod screen. Since the rod screen has no mesh, there is no clogging. The vibrating motor drives the rod screen to vibrate, causing the stone to slide off during the vibration, facilitating screening. The conveyor then transports the fallen stone out, thus completing the screening process.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing stone vibration screening device can only perform simple vibration screening of stones. The vibration amplitude during the vibration process is insufficient, which makes the screening plate easily blocked by stones, thus affecting the subsequent screening effect. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the screening plate cannot be prevented from clogging, and to propose a stone vibration screening device.

[0006] The technical solution of this utility model is: a stone vibration screening device, including a screening box; and further comprising:

[0007] The vibration mechanism is located on the outside of the screening box and is used to vibrate and automatically screen the stones.

[0008] A striking mechanism is located at the bottom of the vibration mechanism and is used to strike the vibration mechanism during its vibration process.

[0009] The installation frame is mounted on the striking mechanism. The outer side of the installation frame is slidably connected to the inner side of the screening box. A striking rod is mounted on the top of the installation frame, and multiple striking rods are arranged around the installation frame. A telescopic tube is mounted on the bottom of the installation frame, and a second spring is mounted on the outer side of the telescopic tube. The installation frame is pressed down by the striking mechanism, which causes the second spring to generate a rebound force on the installation frame. After the installation frame rebounds, it drives the striking rod to strike the vibration mechanism.

[0010] Preferably, a crusher is provided on the top of the vibration mechanism, and a feed pipe is provided on the top of the crusher.

A pull ring is provided at the end of the collection box.

[0013] Preferably, the vibration mechanism includes a discharge port and a vibration assembly;

[0014] The discharge port is located on the side of the screening box and on the top of the collection box;

[0015] The vibration assembly is located on the outside of the screening box and is used for vibrating screening of stones.

[0016] Preferably, the vibration assembly includes a motor, a fixed frame, a screening plate, and a slot;

[0017] The screening plate is located inside the screening box, the slot is located inside the screening box, the slot has a baffle that slides inside the slot, the baffle has a connecting block on the side, the connecting block has a fixed plate on the side away from the baffle, the fixed plate has a sliding block on the side away from the connecting block, the sliding block has a slide rail on the side, the sliding block has a spring at the end, the fixed frame is located at the end of the spring away from the sliding block, the motor is located on the side of the fixed frame, the motor has a rotating shaft at the output end, and the rotating shaft has a vibration block at the end away from the motor.

The rotating frame has three protruding ends, and the ends of the protruding ends are set with arc-shaped surfaces for pressing the connecting frame. The connecting frame is located on the outside of the mounting frame. The sealing plate is located on the connecting frame and is used to seal the connection between the mounting frame and the connecting frame. The bottom of the telescopic tube is equipped with a fixing plate, and the side of the fixing plate is connected to the inside of the screening box.

[0020] Compared with the prior art, this utility model has the following beneficial technical effects: By setting up a striking mechanism and a vibration mechanism, the motor drives the screening plate to vibrate, thereby screening the stones that fall onto the screening plate. At the same time, the motor drives the rotating frame to press the striking rod, and then the striking rod strikes the screening plate. This can effectively prevent stone particles from getting stuck in the screen holes, avoid screen hole blockage, ensure smooth material passage, improve screening efficiency, and make the stones form continuous jumping and turning on the screen surface, promoting material stratification according to particle size. Fine particles are easier to pass through the screen holes, while coarse particles remain on the screen surface. At the same time, it further refines the screening process, making it easier to separate fine particles from coarse particles and improve screening accuracy. Attached Figure Description

A striking rod 605 is provided on the top of the mounting frame 604. Multiple striking rods 605 are arranged around the mounting frame 604. A telescopic tube 606 is provided at the bottom of the mounting frame 604. A second spring 607 is provided on the outer side of the telescopic tube 606. The mounting frame 604 is pressed down by the striking mechanism, which causes the second spring 607 to generate a rebound force on the mounting frame 604. After the mounting frame 604 rebounds, it drives the striking rods 605 to strike the vibration mechanism.

[0031] A crusher 2 is installed on the top of the vibrating mechanism, and a feed pipe 3 is installed on the top of the crusher 2. Stones are fed into the crusher 2 through the feed pipe 3. The stones are crushed in the crusher 2 and then screened in the screening box 1.

[0032] The collection assembly includes a support column 401, a base plate 402, and a placement platform 405. The support column 401 is located at the bottom of the screening box 1, the base plate 402 is located at the bottom of the support column 401, and the placement platform 405 is located on the side of the screening box 1. A collection box 403 is slidably mounted on the top of the placement platform 405. A pull ring 404 is provided at the end of the collection box 403. The collection box 403 is installed on the placement platform 405. After the screened stones are collected, the collection box 403 is replaced by pulling the pull ring 404.

[0033] The vibration mechanism includes a discharge port 501 and a vibration assembly; the discharge port 501 is located on the side of the screening box 1 and on the top of the collection box 403; the vibration assembly is located on the outside of the screening box 1 and is used to vibrate and screen the stone. The vibration assembly includes a motor 503, a fixed frame 506, a screening plate 513, and a slot 502. The screening plate 513 is disposed inside the screening box 1, and the slot 502 is disposed inside the screening box 1. A baffle 512 is slidably disposed inside the slot 502. A connecting block 511 is disposed on the side of the baffle 512. A fixed plate 508 is disposed on the side of the connecting block 511 away from the baffle 512. A sliding block 507 is disposed on the side of the fixed plate 508 away from the connecting block 511. A slide rail 509 is disposed on the side of the sliding block 507. A spring 510 is disposed at the end of the sliding block 507. The fixed frame 506 is disposed at the end of the spring 510 away from the sliding block 507. The motor 503 is disposed on the side of the fixed frame 506. The output end of the motor 503... A rotating shaft 504 is provided, and a vibrating block 505 is provided at the end of the rotating shaft 504 away from the motor 503. The motor 503 drives the rotating shaft 504 to rotate, and the rotating shaft 504 drives the vibrating block 505 to rotate. The vibrating block 505 is configured as a polygonal turntable, and the extended end of the vibrating block 505 is configured as an arc surface on one side and a vertical surface on the other side. When the vibrating block 505 rotates, when the arc surface of the extended end contacts the fixed disk 508, it will gradually press the fixed disk 508 downward. The fixed disk 508 drives the sliding block 507 and the screening plate 513 downward. At this time, the spring 510 deforms. When the arc surface disengages from the fixed disk 508, the fixed disk 508 will contact the vertical surface of the extended end, and will quickly rebound under the action of the spring 510, causing the screening plate 513 to vibrate.

[0034] Example 2

[0035] like Figure 4 As shown, this utility model proposes a stone vibration screening device. Compared with Embodiment 1, this embodiment details the structure of the striking mechanism.

[0036] The striking mechanism includes a rotating frame 601, a connecting frame 602, and a sealing plate 603. The rotating frame 601 is located at the end of the rotating shaft 504 away from the motor 503. The rotating frame 601 has three protruding ends, and the ends of the protruding ends are set with arc-shaped surfaces for pressing the connecting frame 602. The connecting frame 602 is located on the outside of the mounting frame 604. The sealing plate 603 is located on the connecting frame 602 and is used to seal the connection between the mounting frame 604 and the connecting frame 602. The bottom of the telescopic tube 606 is provided with a fixing plate, and the side of the fixing plate is connected to the inside of the screening box 1. The rotating frame 601 rotates under the drive of the rotating shaft 504. When it rotates to the connecting frame 602, it drives the connecting frame 602 to press down. The connecting frame 602 drives the mounting frame 604 to press down, thereby driving the striking rod 605 to press down. After the rotating frame 601 is separated from the connecting frame 602, the mounting frame 604 rebounds under the action of the second spring 607, thereby driving the striking rod 605 to strike the screening plate 513.

[0037] In summary, when using this utility model, the stone is fed into the crusher 2 through the feed pipe 3. The stone is crushed in the crusher 2, and the crushed stone enters the screening box 1. The motor 503 is started, and the motor 503 drives the rotating shaft 504 to rotate. The rotating shaft 504 drives the vibrating block 505 to rotate. When the vibrating block 505 rotates, the arc-shaped surface of the extended end contacts the fixed plate 508 and gradually presses the fixed plate 508 downward. The fixed plate 508 drives the sliding block 507 and the screening plate 513 downward. At this time, the spring 510 deforms. When the arc-shaped surface disengages from the fixed plate 508, the fixed plate 508 will contact the vertical surface of the extended end, and will quickly rebound under the action of the spring 510, so that the screening box... When the screening plate 513 vibrates, the rotating frame 601 rotates under the drive of the rotating shaft 504. When it rotates to the connecting frame 602, it causes the connecting frame 602 to press down. The connecting frame 602 causes the mounting frame 604 to press down, which in turn causes the striking rod 605 to press down. After the rotating frame 601 disengages from the connecting frame 602, the mounting frame 604 rebounds under the action of the second spring 607, which causes the striking rod 605 to strike the screening plate 513, thereby further enhancing the vibration effect of the screening plate 513 and preventing the screening plate 513 from clogging. Smaller stones fall through the screening holes on the screening plate 513 onto the bottom plate 402, while larger stones fall through the inclined surface of the screening plate 513 into the collection box 403.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
