Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a hydraulic high-frequency vibrating screen with adjustable tilt angle. Background Technology

[0002] A high-frequency vibrating screen, or simply a high-frequency screen, consists of components such as a vibrator, slurry distributor, screen frame, machine frame, suspension springs, and screen mesh. It is one of the most important screening machines in the mineral processing industry. It is used to separate ores containing solids and crushed ore. The frequency of the vibrating screen is mainly controlled by an electromagnetic vibrator mounted above the screen and directly connected to its surface. Its high-frequency characteristics distinguish it from ordinary vibrating screens. High-frequency vibrating screens typically operate at an inclined angle, traditionally varying between 0-25 degrees, with a maximum angle of 45 degrees. Furthermore, it should operate at low strokes, with a frequency range of 1500-7200 rpm.

[0003] According to a public notice (No. CN214077748U), an adjustable-angle hydraulic high-frequency vibrating screen is provided at the bottom of the vibrating screen box. The mounting plate and vibrating motor included in the vibrating device can be adjusted in angle as needed. The hydraulic cylinder extends and retracts, causing the mounting plate to change its inclination, thereby changing the inclination of the vibrating device and improving the screening efficiency of the vibrating screen box.

[0004] However, in actual use, after the vibrating screen adjusts the angle of the vibrating motor mounting plate at the bottom, although bolts are used to fix the connection between the hydraulic rod and the mounting plate, the hinge position relies solely on the hinge rod to bear the torsional force caused by continuous high-frequency vibration, which can easily lead to wear and even breakage, thus affecting the normal use of the vibrating screen. In view of this, we propose a hydraulic high-frequency vibrating screen with adjustable tilt angle. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic high-frequency vibrating screen with adjustable tilt angle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-angle hydraulic high-frequency vibrating screen, comprising a base, an elastic telescopic column fixedly mounted on the upper surface of the base, a screen box hinged to the top of the elastic telescopic column, a feed inlet on the top outer wall of the screen box, a discharge outlet on the inner wall of the end of the screen box away from the feed inlet, a mounting base fixedly mounted on the lower surface of the screen box, a connecting rod hinged to the lower surface of the mounting base, a mounting plate hinged to the bottom end of the connecting rod, a vibrating motor fixedly mounted on the lower surface of the mounting plate, and a reinforcing component provided between the mounting plate and the mounting base;

[0007] The reinforcing component includes a hinged sleeve, which is fixedly installed on the lower surface of the mounting base. A transmission rod is rotatably mounted through the inner wall of the hinged sleeve. A connecting block is fixedly mounted through the arc-shaped outer wall of the transmission rod. A hydraulic rod is fixedly connected to the outer wall of the end of the connecting block. An arc-shaped groove is formed on the arc-shaped outer wall of the end of the transmission rod. A bidirectional screw is rotatably mounted on the inner wall of the mounting base. A reinforcing sleeve is threadedly connected to the outer wall of the bidirectional screw. A limit hole is formed on the inner wall of the reinforcing sleeve. An arc-shaped protrusion is fixedly mounted on the arc-shaped inner wall of the limit hole.

[0008] Preferably, the hydraulic rod includes a fixed end and a movable end. Two sets of connecting blocks are provided, and the two sets of connecting blocks are respectively disposed on the outer walls of the fixed end and the movable end of the hydraulic rod. Specifically, another set of transmission rods is installed through and fixedly mounted on the inner wall of the connecting block on the surface of the movable end of the hydraulic rod. At the same time, the mounting plate is provided with a bidirectional screw, a reinforcing sleeve and a hinge sleeve corresponding to the top of the hydraulic rod, so that when the hydraulic rod is started to extend and shorten, the mounting plate can be controlled to deflect at a certain angle with the hinge point between it and the connecting rod as the center of rotation.

[0009] Preferably, the reinforcing sleeve has a threaded hole inside that matches the bidirectional screw, and the surface of the reinforcing sleeve away from the hydraulic rod is T-shaped. The inner wall of the mounting base has a T-shaped groove that matches the T-shaped surface of the reinforcing sleeve, so that when the bidirectional screw rotates, the two sets of reinforcing sleeves can only move towards or away from each other along the inner wall of the mounting base.

[0010] Preferably, the outer diameter of the transmission rod is adapted to the inner diameter of the limiting hole, and the axis of the transmission rod and the axis of the limiting hole are arranged on the same straight line, so that the linear movement of the reinforcing sleeve can achieve the approach and departure of the end of the transmission rod.

[0011] Preferably, the arc-shaped protrusion is adapted to the size of the arc-shaped groove, so that when the reinforcing sleeve moves to be fitted onto the outside of the transmission rod, the arc-shaped protrusion can enter the arc-shaped groove to increase the contact area between the end of the transmission rod and the reinforcing sleeve.

[0012] Preferably, a clamping assembly is provided between the reinforcing sleeve and the hinge sleeve. The clamping assembly includes an annular toothed groove, which is formed on the outer surface of the hinge sleeve away from the connecting block. An insert plate is slidably installed on the inner wall of the reinforcing sleeve near the hinge sleeve end. A spring is fixedly connected between the end of the insert plate and the inner wall of the reinforcing sleeve.

[0013] Preferably, the inner surface of the annular toothed groove is provided with a plurality of toothed blocks arranged in a circumferential array, and the insert plate is arranged in an arc shape, and the arc of the insert plate is adapted to the annular toothed groove. Multiple sets of locking blocks are provided on the outer wall of the insert plate near the annular toothed groove, and the gap between the locking blocks and the plurality of toothed blocks is adapted to ensure the stability of the connection between the reinforcing sleeve and the hinge sleeve after the insert plate enters the annular toothed groove.

[0014] Compared with the prior art, this utility model provides a hydraulic high-frequency vibrating screen with adjustable tilt angle, which has the following beneficial effects:

[0015] 1. This adjustable-angle hydraulic high-frequency vibrating screen, equipped with reinforcing components, allows for adjustment. Rotating the bidirectional screw controls the two sets of reinforcing sleeves to approach each other along the screw's surface. Ultimately, the end of the transmission rod is fully inserted into the limiting hole, and the arc-shaped protrusion enters the arc-shaped groove, increasing the contact area between the transmission rod end and the reinforcing sleeve. This ensures the mounting plate and vibrating motor maintain a more stable state after the angle is adjusted, preventing excessive wear or even breakage at the connection point between the hydraulic rod and the mounting plate when the vibrating motor vibrates, thus guaranteeing the normal and safe operation of the device.

[0016] 2. This adjustable-angle hydraulic high-frequency vibrating screen, by being equipped with a clamping assembly, allows the insert plate to be inserted into the annular toothed groove when the reinforcing sleeve moves toward the hinged sleeve side. Through the mutual cooperation between the insert plate and the annular toothed groove, the connection strength and stability of the transmission rod and the connecting block are further guaranteed. Thus, even under high-frequency vibration working conditions, the stable connection between the mounting plate and the mounting base can be guaranteed, reducing the damage rate of the device and increasing its service life.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: an adjustable-angle hydraulic high-frequency vibrating screen, including a base 1, an elastic telescopic column 2 fixedly installed on the upper surface of the base 1, a screen box 3 hinged to the top of the elastic telescopic column 2, a feed inlet 31 opened on the top outer wall of the screen box 3, a discharge outlet 32 ​​opened on the inner wall of the end of the screen box 3 away from the feed inlet 31, a mounting base 4 fixedly installed on the lower surface of the screen box 3, a connecting rod 5 hinged to the lower surface of the mounting base 4, a mounting plate 6 hinged to the bottom end of the connecting rod 5, a vibrating motor 7 fixedly installed on the lower surface of the mounting plate 6, and a reinforcing component 8 provided between the mounting plate 6 and the mounting base 4. The reinforcing component 8 includes a hinge sleeve 81, a transmission rod 82, a connecting block 83, a hydraulic rod 84, an arc groove 85, a bidirectional screw 86, a reinforcing sleeve 87, a limiting hole 88, and an arc-shaped protrusion 89.

[0024] In one embodiment of this utility model, a hinge sleeve 81 is fixedly installed on the lower surface of the mounting base 4. A transmission rod 82 is rotatably installed through the inner wall of the hinge sleeve 81. A connecting block 83 is fixedly installed through the arc-shaped outer wall of the transmission rod 82. A hydraulic rod 84 is fixedly connected to the outer wall of the end of the connecting block 83. An arc-shaped groove 85 is provided on the arc-shaped outer wall of the end of the transmission rod 82. A bidirectional screw 86 is rotatably installed on the inner wall of the mounting base 4. A reinforcing sleeve 87 is threadedly connected to the outer wall of the bidirectional screw 86. A limiting hole 88 is provided on the inner wall of the reinforcing sleeve 87. An arc-shaped protrusion 89 is fixedly installed on the arc-shaped inner wall of the limiting hole 88.

[0025] Furthermore, four elastic telescopic columns 2 are provided, and each pair of elastic telescopic columns 2 are mirror images of each other on the left and right sides of the vertical central axis of the base 1. The length of each pair of elastic telescopic columns 2 is the same, so that the screen box 3 can obtain a better vibration displacement in the vertical direction when vibrating and screening, thereby ensuring the vibration screening effect of the screen box 3. At the same time, two sets of connecting rods 5 are provided, and the two sets of connecting rods 5 are located on the front and rear sides of the mounting base 4. Specifically, two sets of reinforcing components 8 are provided, and the two sets of reinforcing components 8 and connecting rods 5 are symmetrically arranged on the left and right sides of the mounting base 4. This allows the mounting plate 6 to deflect at a certain angle around the connection point between the connecting rod 5 and the mounting plate 6 when the hydraulic rod 84 in the reinforcing component 8 is extended, thereby realizing the adjustment of the tilt angle of the vibrating motor 7, so as to adapt to the vibration screening requirements of different materials and strengths.

[0026] In addition, two sets of hinged sleeves 81 are provided, and the two sets of hinged sleeves 81 are symmetrically arranged about the vertical central axis of the connecting block 83, so that the force on the transmission rod 82 is more balanced. Meanwhile, the hydraulic rod 84 includes a fixed end and a movable end, and two sets of connecting blocks 83 are provided, with the two sets of connecting blocks 83 respectively located on the outer walls of the fixed end and the movable end of the hydraulic rod 84. Specifically, another set of transmission rods 82 is fixedly installed through and on the inner wall of the connecting block 83 on the movable end surface of the hydraulic rod 84. At the same time, the mounting plate 6 contains a bidirectional screw 86, a reinforcing sleeve 87, and a hinged sleeve 81 corresponding to the top of the hydraulic rod 84, thereby... When the hydraulic rod 84 is extended and shortened, it can control the mounting plate 6 to deflect at a certain angle with the hinge point between it and the connecting rod 5 as the center of rotation. Furthermore, the reinforcing sleeve 87 has a threaded hole inside that matches the bidirectional screw 86, and the surface of the end of the reinforcing sleeve 87 away from the hydraulic rod 84 is set in a T-shape. The inner wall of the mounting base 4 has a T-shaped groove that matches the T-shaped surface of the reinforcing sleeve 87, so that when the bidirectional screw 86 rotates, the two sets of reinforcing sleeves 87 can only move towards or away from each other along the inner wall of the mounting base 4, thereby allowing the reinforcing sleeve 87 to move closer to or further away from the end of the transmission rod 82.

[0027] Meanwhile, the outer diameter of the transmission rod 82 is matched with the inner diameter of the limiting hole 88, and the axis of the transmission rod 82 and the limiting hole 88 are set on the same straight line. This allows the linear movement of the reinforcing sleeve 87 to move closer to and further away from the end of the transmission rod 82. In addition, the size of the arc-shaped protrusion 89 is matched with the size of the arc-shaped groove 85. This allows the arc-shaped protrusion 89 to enter the arc-shaped groove 85 when the reinforcing sleeve 87 moves to be fitted on the outside of the transmission rod 82, thereby increasing the contact area between the end of the transmission rod 82 and the reinforcing sleeve 87. This allows the mounting plate 6 and the vibration motor 7 to maintain a more stable state after the tilt angle is adjusted. This prevents excessive wear or even breakage of the connection point between the hydraulic rod 84 and the mounting plate 6 when the vibration motor 7 vibrates, thus ensuring the normal and safe operation of the device.

[0028] Please refer to the attached instruction manual. Figure 5 A clamping component 9 is provided between the reinforcing sleeve 87 and the hinge sleeve 81. The clamping component 9 includes an annular toothed groove 91, which is opened on the outer surface of the hinge sleeve 81 away from the connecting block 83. An insert plate 92 is slidably installed on the inner wall of the reinforcing sleeve 87 near the hinge sleeve 81. A spring 93 is fixedly connected between the end of the insert plate 92 and the inner wall of the reinforcing sleeve 87.

[0029] In an embodiment of this utility model, a plurality of toothed blocks are arranged in a circumferential array on the inner surface of the annular toothed groove 91, and the insert plate 92 is arc-shaped, with the curvature of the insert plate 92 matching that of the annular toothed groove 91. This allows the insert plate 92 to be inserted into the annular toothed groove 91 when the reinforcing sleeve 87 moves toward the hinged sleeve 81. Simultaneously, a plurality of locking blocks are provided on the outer wall of the insert plate 92 near the annular toothed groove 91, and the gaps between the locking blocks and the toothed blocks are matched to ensure that the reinforcing sleeve 87 can be securely inserted into the annular toothed groove 91 after the insert plate 92 enters the annular toothed groove 91. The stability of the connection between 87 and the hinge sleeve 81 is ensured. In addition, multiple sets of insert plates 92 are arranged in a circumferential array on the inner wall of the end of the reinforcing sleeve 87. This allows the reinforcing sleeve 87 to move to the outside of the transmission rod 82. Through the mutual cooperation between the insert plates 92 and the annular toothed groove 91, the connection strength and stability between the transmission rod 82 and the connecting block 83 are further guaranteed. This ensures the stable connection between the mounting plate 6 and the mounting base 4 even under high-frequency vibration conditions, reducing the damage rate of the device and increasing its service life.

[0030] In this invention, during use, the hydraulic rod 84 is activated to control its extension or shortening, thereby allowing the mounting plate 6 to deflect at a certain angle around the connection point between the connecting rod 5 and the mounting plate 6. This adjusts the tilt angle of the vibrating motor 7, adapting to the vibrating screening requirements of different materials and intensities. After adjustment, the bidirectional screw 86 is rotated to control the two sets of reinforcing sleeves 87 to approach each other along the surface of the bidirectional screw 86. Finally, the end of the transmission rod 82 is fully inserted into the limiting hole 88, and the arc-shaped protrusion 89 enters the arc-shaped groove 85, increasing the contact area between the end of the transmission rod 82 and the reinforcing sleeve 87. This ensures that the mounting plate 6 and the vibrating motor 7 maintain a more stable state after the tilt angle is adjusted, preventing excessive wear or even breakage of the connection point between the hydraulic rod 84 and the mounting plate 6 when the vibrating motor 7 vibrates, thus ensuring the normal and safe operation of the device.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
