Description

Technical Field

[0001] This utility model belongs to the field of vibrating screen technology, and specifically relates to a vibrating screen frame connecting bracket that is easy to assemble and disassemble. Background Technology

[0002] A vibrating screen works by using the reciprocating rotary vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two forces causes the screen surface to produce complex rotary vibration. The vibration trajectory is a complex spatial curve. The projection of this curve on the horizontal plane is a circle, while its projection on the vertical plane is an ellipse.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN210546285U, authorized on May 19, 2020, discloses a corn kernel vibrating separator screen device, including a support frame. The support frame has four fixed frames suspended from its sides. A vibrating screen box, connected at one end to the fixed frame via a fixed seat, is obliquely positioned above the fixed frames. A vibrating motor is mounted on the fixed seat. The other end of the vibrating screen box is fixedly connected to the fixed frame via a connector. A feed port is located on the top surface of the vibrating screen box. Inside the vibrating screen box, a first screen and a second screen, parallel to the bottom plate of the vibrating screen box, are arranged at intervals from top to bottom. The bottom plate of the vibrating screen box has a first impurity discharge channel connected to the lower end of the bottom plate, a corn kernel discharge channel connected to the lower end of the second screen, and a second impurity discharge channel connected to the lower end of the first screen. This corn kernel vibrating separator screen device has a compact structure and facilitates the removal of corn kernels and impurities.

[0004] However, this device still has the following drawbacks: Although it is convenient for removing corn kernels and impurities, the screen is the part of the vibrating separator that directly contacts the corn kernels, making it prone to accumulating impurities and residues. Because the screen is not easily disassembled, cleaning it becomes very difficult, and may even be impossible to clean thoroughly. A screen that is not cleaned for a long time may cause the screen holes to become clogged, reducing screening efficiency and even affecting screening quality. With increased use, the screen may need to be replaced due to wear, corrosion, or damage. If the screen is not easy to disassemble, the replacement process will be very cumbersome, and may even require disassembling the entire vibrating separator. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a vibrating screen frame connecting bracket that is easy to assemble and disassemble, including a base plate, a support frame at the top of the base plate, a vibrating motor at the bottom of the support frame, and telescopic rods fixedly connected to the four corners of the top of the base plate. The output ends of the telescopic rods are connected to the support frame in a transmission manner. A first spring is sleeved on the surface of the telescopic rod, and the two ends of the first spring are fixedly connected to the base plate and the support frame, respectively. A fixing frame is fixedly connected to the top of the support frame, and a screen plate is provided on the top of the fixing frame. Fixing blocks are embedded on both sides of the top of the fixing frame. The inner cavity of the fixing block is provided with a locking mechanism and an adjusting mechanism, and a connecting block is provided on one side of the fixing block.

[0006] Furthermore, the locking mechanism includes two T-shaped blocks slidably connected to the top of the inner cavity of the fixed block. A tension spring is fixedly connected to one side of each T-shaped block, and one end of the tension spring is fixedly connected to the fixed block. A locking block is fixedly connected to the bottom of each T-shaped block. A wedge block is provided on one side of each of the two locking blocks. A first short rod is fixedly connected to the bottom of each wedge block. Grooves are provided on both sides of the sieve plate, and slots that match the locking blocks are provided on both sides of the inner cavity of the grooves.

[0007] Furthermore, the adjusting mechanism includes a connecting rod rotatably connected to the inner cavity of the fixed block. Two adjusting blocks are sleeved on the surface of the connecting rod. A first moving block and a second moving block are provided on opposite sides of the two adjusting blocks. The top of the first moving block is fixedly connected to a first short rod. A first guide rod is provided in the inner cavity of the first moving block. A second guide rod is provided in the inner cavity of the second moving block. Both ends of the first guide rod and the second guide rod are fixedly connected to the adjusting blocks. A second short rod is fixedly connected to one side of the second moving block. One end of the second short rod extends through to the outside of the fixed block and is rotatably connected to the connecting block. A second spring is sleeved on the surface of the second short rod. Both ends of the second spring are fixedly connected to the fixed block and the second moving block, respectively.

[0008] Furthermore, a limiting rod is fixedly connected to one side of the inner cavity of the fixed block, a limiting block is slidably connected to the surface of the limiting rod, and the bottom of the limiting block is fixedly connected to the second moving block.

[0010] Furthermore, a material box is slidably connected to the bottom of the inner cavity of the support frame, and a handle is fixedly connected to one side of the material box.

[0011] Furthermore, a mounting base is fitted onto the surface of the vibration motor, and bolts are threaded onto both sides of the bottom of the mounting base. The support frame and the vibration motor are detachably connected by bolts.

[0012] Furthermore, support legs are fixedly connected to the four corners of the bottom of the base plate, and the four support legs are arranged symmetrically.

[0013] The beneficial effects of this utility model are:

[0014] 1. The locking mechanism in this device ensures the screen plate is securely locked in the fixed block. When the locking block and the slot are fully engaged, the screen plate will not move or fall off during operation, guaranteeing the stability and safety of the equipment. Furthermore, when the user needs to disassemble the screen plate, the adjustment mechanism allows the user to simply move the connecting block to trigger the entire adjustment mechanism, thereby locking and unlocking the screen plate. This not only facilitates disassembly but also improves the overall coordination and operational efficiency of the equipment.

[0015] 2. In this device, the combination of the limiting rod and the limiting block guides and supports the second moving block, improving its stability during movement. The combination of the positioning column and the positioning groove limits the connecting block, making it less likely to spring back. The combination of the material box and the handle allows the material box to store the screened material, increasing the contact between the user's hand and the handle, making it easier for the user to pick up the material box.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model embodiment provides a vibrating screen frame connecting bracket that is easy to assemble and disassemble, including a base plate 1, exemplarily, such as... Figures 1-6 As shown.

[0027] A support frame 2 is provided on the top of the base plate 1, and a vibration motor 3 is provided on the bottom of the support frame 2. Telescopic rods 4 are fixedly connected to the four corners of the top of the base plate 1. The output end of the telescopic rods 4 is connected to the support frame 2. A first spring 5 is sleeved on the surface of the telescopic rod 4. The two ends of the first spring 5 are fixedly connected to the base plate 1 and the support frame 2 respectively. A fixed frame 6 is fixedly connected to the top of the support frame 2. A sieve plate 7 is provided on the top of the fixed frame 6. Fixed blocks 8 are embedded on both sides of the top of the fixed frame 6. A locking mechanism 9 and an adjusting mechanism 10 are provided in the inner cavity of the fixed block 8. A connecting block 11 is provided on one side of the fixed block 8.

[0028] The locking mechanism 9 includes two T-shaped blocks 91 that are slidably connected to the top of the inner cavity of the fixed block 8, such as... Figures 1-6 As shown.

[0029] A tension spring 92 is fixedly connected to one side of the T-shaped block 91. One end of the tension spring 92 is fixedly connected to the fixing block 8. A locking block 93 is fixedly connected to the bottom of the T-shaped block 91. A wedge block 94 is provided on the opposite side of the two locking blocks 93. A first short rod 95 is fixedly connected to the bottom of the wedge block 94. Grooves 96 are provided on both sides of the sieve plate 7. The inner cavities of the grooves 96 are provided on both sides of the grooves 96, and slots 97 that are adapted to the locking blocks 93 are provided.

[0030] Specifically, the locking mechanism 9 achieves a stable lock of the screen plate 7 in the fixed block 8 through the cooperation of the T-shaped block 91 and the locking block 93, as well as the rebound force of the tension spring 92. When the locking block 93 is fully engaged with the slot 97, it can ensure that the screen plate 7 will not move or fall off at will during operation, thus ensuring the stability and safety of the equipment.

[0031] The adjusting mechanism 10 includes a connecting rod 101 rotatably connected to the inner cavity of the fixed block 8, such as... Figures 1-6 As shown.

[0032] Two adjusting blocks 102 are sleeved on the surface of the connecting rod 101. A first moving block 103 and a second moving block 105 are provided on opposite sides of the two adjusting blocks 102. The top of the first moving block 103 is fixedly connected to the first short rod 95. A first guide rod 104 is provided in the inner cavity of the first moving block 103. A second guide rod 106 is provided in the inner cavity of the second moving block 105. Both ends of the first guide rod 104 and the second guide rod 106 are fixedly connected to the adjusting block 102. A second short rod 107 is fixedly connected to one side of the second moving block 105. One end of the second short rod 107 passes through to the outside of the fixed block 8 and is rotatably connected to the connecting block 11. A second spring 108 is sleeved on the surface of the second short rod 107. Both ends of the second spring 108 are fixedly connected to the fixed block 8 and the second moving block 105, respectively.

[0033] Specifically, by adjusting the mechanism 10, the linkage between various components is realized. Users only need to move the connecting block 11 to trigger the movement of the entire adjusting mechanism 10, thereby locking and unlocking the sieve plate 7, which improves the overall coordination and operating efficiency of the equipment.

[0034] A limiting rod 12 is fixedly connected to one side of the inner cavity of the fixing block 8, such as... Figures 1-6 As shown.

[0035] The surface of the limiting rod 12 is slidably connected to the limiting block 13. The bottom of the limiting block 13 is fixedly connected to the second moving block 105. Positioning posts 15 are fixedly connected to both sides of the fixed frame 6. A positioning groove 14 adapted to the positioning post 15 is opened on one side of the connecting block 11. A material box 16 is slidably connected to the bottom of the inner cavity of the support frame 2. A handle 17 is fixedly connected to one side of the material box 16. An mounting seat 18 is sleeved on the surface of the vibration motor 3. Bolts are threadedly connected to both sides of the bottom of the mounting seat 18. The support frame 2 and the vibration motor 3 are detachably connected by bolts. Support legs 19 are fixedly connected to the four corners of the bottom of the base plate 1. The four support legs 19 are symmetrically arranged.

[0036] Specifically, the combination of the limiting rod 12 and the limiting block 13 guides and supports the second moving block 105, improving its stability during movement. The combination of the positioning column 15 and the positioning groove 14 limits the connecting block 11, preventing it from easily rebounding. The combination of the material box 16 and the handle 17 stores the screened material, increasing the contact between the user's hand and the handle 17, making it easier for the user to pick up the material box 16. The combination of the mounting base 18 and the bolts secures the vibrating motor 3 and facilitates disassembly and maintenance. The support leg 19 supports the connecting frame, improving its stability during placement.

[0037] The working principle of the vibrating screen frame connecting bracket that is easy to assemble and disassemble, as proposed in this embodiment of the utility model, is as follows:

[0038] When in use, the user moves the connecting block 11, which in turn moves the second short rod 107. The second short rod 107 then moves the second moving block 105. As the second moving block 105 moves, it causes the second guide rod 106 to slide within its inner cavity, thereby causing the adjusting block 102 to move in an arc around the connecting rod 101. As the second moving block 105 moves, it compresses the second spring 108. As the adjusting block 102 moves in an arc, it causes the first guide rod 104 to slide within the inner cavity of the first moving block 103, thereby causing the first moving block 103 to move upward.

[0039] Furthermore, the first moving block 103 drives the first short rod 95 to move upward. When the first short rod 95 moves, the rebound force of the tension spring 92 will drive the two T-shaped blocks 91 to move relative to each other. The T-shaped blocks 91 drive the locking block 93 to gradually disengage from the inner cavity of the locking groove 97 and retract into the inner cavity of the fixed block 8. When the locking block 93 is fully inserted into the inner cavity of the fixed block 8, the connecting block 11 is rotated so that one side of the connecting block 11 is flush with the positioning post 15. Then the connecting block 11 is released, and the elastic force of the second spring 108 causes the positioning post 15 to enter the inner cavity of the positioning groove 14 for limiting. Then the user can disassemble the screen plate 7 by moving it upward.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
