Description

Technical Field

[0001] This utility model relates to the field of separation screen technology, specifically a hydraulically driven adjustable tilt separation screen. Background Technology

[0002] Sand and gravel refer to a loose mixture of sand and gravel. During the extraction of sand and gravel, due to the varying particle sizes and the presence of water and fine soil particles, sieves are used to screen the sand and gravel to improve its purity and quality.

[0003] Existing separating screen structures are designed for specific materials with fixed feeding angles, resulting in poor adaptability to conveying different materials. The fixed inclination angle has a significant impact on the screening of different materials; when the friction angle of the material's outer surface increases, feeding difficulties arise, severely affecting the working efficiency of the separating screen. An unreasonable inclination angle also leads to poor material screening. Therefore, we propose a hydraulically driven adjustable inclination separating screen. Utility Model Content

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1-5 As shown, the present invention provides a technical solution: a hydraulically driven adjustable tilt separation screen, comprising: a separation screen 1; a support 2 is provided on both sides of one end of the separation screen 1, and a frame assembly 3 is rotatably provided below the support 2, the separation screen 1 rotates on the frame assembly 3 via the support 2; a hinge seat 4 is provided on one side of the top of the frame assembly 3, and a hydraulic cylinder 5 is rotatably connected to the hinge seat 4, the top of the hydraulic cylinder 5 is rotatably connected to a hinge seat 6 fixed on the outside of the separation screen 1, a positioning rod 7 located on one side of the hydraulic cylinder 5 is rotatably connected to the hinge seat 6, and a locking module 8 for fixing the positioning rod 7 is provided on one side of the hinge seat 4.

[0024] In this embodiment, it includes: a separating sieve 1;

[0025] Specifically, the separating screen 1 includes an outer shell, and a screen plate 11 is provided in the middle of the outer shell. One end of the separating screen 1 is provided with a discharge port 13 and a discharge port 14 located above and below the screen plate 11, respectively. The other end of the separating screen 1 is provided with a feeding pipe 12. The general working principle of the separating screen is that the material is connected to the feeding pipe 12 and introduced into the interior of the outer shell of the separating screen 1. The screen plate 11 is used to separate different materials. The separated material components are discharged from the discharge port 13 and the discharge port 14, respectively, thereby realizing the separation of materials.

[0026] In this embodiment, a support 2 is provided on both sides of one end of the separating screen 1, and a frame assembly 3 is rotatably arranged below the support 2. The separating screen 1 rotates on the frame assembly 3 through the support 2.

[0027] Specifically, the support 2 has a C-shaped structure. This integrated C-shaped support provides greater stability and ensures stable support for the separating screen 1. The support 2 includes an integrated bracket 22 and a connecting plate 21 fixed to the separating screen 1. The connecting plate 21 is bolted to the side wall of the separating screen 1. Pins 23 are fixed on both sides of the integrated bracket 22. The support 2 is fixed relative to the separating screen 1 and rotates with it. The frame assembly 3 includes a base plate 31 on the ground. Support legs 32 are fixed to the top of the base plate 31, and the upper part of the support legs 32 is rotatably connected to the pins 23 via bushings. When the tilt angle of the separating screen 1 needs to be adjusted, the pin 23 at the top of the frame assembly 3 serves as a fulcrum. With the extension and retraction of the hydraulic cylinder 5, the separating screen 1 rotates at the fulcrum, thus adjusting the tilt angle.

[0028] In this embodiment, a hinge seat 4 is provided on one side of the top of the frame assembly 3, and a hydraulic cylinder 5 is rotatably connected to the hinge seat 4. The top of the hydraulic cylinder 5 is rotatably connected to a hinge seat 6 fixed on the outside of the separating screen 1. The hydraulic cylinder 5 extends and retracts, and as the hydraulic cylinder rotates on the hinge seat 4 and the hinge seat 6, the tilt angle of the separating screen 1 is adjusted.

[0029] Specifically, a shaft 61 is provided in the middle of the hinge seat 2 6, and a shaft 62 is provided on one side of the hinge seat 2 6. A connector 52 is provided at one end of the hydraulic cylinder 5, and the connector 52 is rotatably connected to the shaft 61. The inner rod of the hydraulic cylinder 5 is fixed on the connector 52, realizing the rotatable connection between the hydraulic cylinder 5 and the hinge seat 2 6. One end of the positioning rod 7 is rotatably connected to the shaft 62. When the hydraulic cylinder 5 is used to adjust the tilt angle of the separating screen 1, the positioning rod 7 rotates accordingly. The positioning rod 7 always remains parallel to the hydraulic cylinder 5.

[0030] In this embodiment, a positioning rod 7 located on one side of the hydraulic cylinder 5 is rotatably connected to the second hinge seat 6, and a locking module 8 for fixing the positioning rod 7 is provided on the upper side of the first hinge seat 4.

[0031] Specifically, the locking module 8 includes a housing 81 fixed to one side of the top of the hinge seat 4. A positioning rod 7 is slidably inserted into the housing 81. A rotating joint 84 is provided on the top of the housing 81, and a lever 83 is provided on the rotating joint 84. One end of the lever 83 is fixedly connected to a locking head 82. A spring 85 is provided on one side of the top of the housing 81, located between the housing 81 and the lever 83. A retaining sleeve 86 for limiting the lever 83 is provided on one side of the housing 81, and the retaining sleeve 86 is slidably inserted into the inside of one side of the housing 81. Inclined teeth are provided on the top outer wall of the positioning rod 7, and the locking head 82 engages in the groove of the inclined teeth. When the tilt angle of the separating screen 1 is adjusted using the hydraulic cylinder 5, the positioning rod 7 rotates accordingly. When the hydraulic cylinder 5 is used to adjust the tilt angle of the separating screen 1... Before adjusting the tilt angle, the operator can insert the ferrule 86 into the inside of the housing 81, so that the ferrule 86 is engaged with the end of the lever 83. At this time, the spring 85 is compressed by the lever 83, and the lever 83 rotates along the rotating joint 84. At this time, the ferrule 82 separates from the helical teeth on the positioning rod 7, allowing the positioning rod 7 to slide freely inside the housing 81. After the adjustment is completed, the hydraulic cylinder 5 is activated to adjust the tilt angle of the separating screen 1. After the adjustment is completed, the reverse operation is performed again to lock the positioning rod 7 on the hinge seat 4 by the locking module 8, thereby avoiding the hydraulic cylinder 5 from being always under force or under a single force. Even if the external force on the hydraulic cylinder 5 is released, the positioning rod 7 can still achieve a stable support effect for the separating screen 1.
