Description
Technical Field
[0001] This utility model relates to the field of screening machine technology, specifically a high-efficiency and energy-saving vibrating screening machine. Background Technology
[0002] In the construction industry, with the acceleration of urbanization, high-rise buildings and large-scale infrastructure projects have sprung up like mushrooms after rain, leading to an explosive growth in the demand for aggregates such as sand and gravel for construction. Moreover, the requirements for their particle size distribution, purity and other quality indicators are becoming increasingly stringent. High-efficiency and energy-saving vibrating screens can accurately and quickly screen out sand and gravel aggregates of different particle sizes to meet the fine proportioning requirements of raw materials in concrete production and other processes, and ensure the quality of construction projects.
[0003] Existing technologies typically involve simply dumping all the material into the device at once. This results in the device facing a large instantaneous load when starting the screening process, necessitating high-power operation to propel the material through the screening process. Due to the lack of prior prediction and adaptive adjustments for material quantity and characteristics, the motor often maintains a high-power output state for extended periods, leading to significant unnecessary energy consumption. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency and energy-saving vibrating screen to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving vibrating screen, comprising:
[0006] A screening frame, wherein a feed inlet is fixedly connected to the top of the screening frame and a connecting rod is fixedly connected to the bottom of the screening frame;
[0007] A transmission assembly is placed inside a screening frame. The transmission assembly includes a first screening plate slidably connected inside the screening frame. A fixed rod is slidably connected to the first screening plate. A transmission plate is fixedly connected to the bottom of the fixed rod. A second sliding rod and a first sliding rod are slidably connected to the bottom of the transmission plate. A transmission rod is fixedly connected to both the second sliding rod and the first sliding rod. The transmission plate is fixedly connected to the first screening plate. A fixed frame is fixedly connected to the fixed rod. A toggle block is fixedly connected to the fixed frame. A second screening plate is slidably connected to the toggle block.
[0008] A shock-absorbing rod is placed inside the screening frame, and a damper is fixedly connected to the shock-absorbing rod.
[0009] Furthermore, the second sliding rod and the first sliding rod are respectively fixedly connected to both ends of the transmission rod, and an installation frame is fixedly connected inside the screening frame, and the damping is fixedly connected inside the installation frame.
[0010] The above technical solution involves installing the motor in the mounting slot on the screening frame and fixing it to the shock absorber rod. With damping provided, the shock absorber rod can be used to reduce the vibration of the motor during use, preventing the motor from falling off.
[0011] Furthermore, a mounting groove is provided on the side of the screening frame near the transmission rod, and an opening is provided in the mounting groove on the screening frame, and the transmission rod is slidably connected in the opening on the screening frame.
[0012] The above technical solution is adopted: by opening an installation groove on the screening frame, it is convenient to install the motor.
[0013] Furthermore, a sliding groove is provided at the bottom of the transmission plate, and both the first sliding rod and the second sliding rod are slidably connected in the sliding groove at the bottom of the transmission plate.
[0014] The above technical solution is adopted: by opening a sliding groove at the bottom of the transmission plate, it can guide the sliding of the first sliding rod and the second sliding rod during use. The length of the second sliding rod is twice that of the first sliding rod. When the first sliding rod and the second sliding rod slide at the bottom of the transmission plate, the transmission plate will shake.
[0015] Furthermore, a fixing plate is fixedly connected to the screening frame, and a universal joint is fixedly connected to the fixing plate. The universal joint on the fixing plate is fixedly connected to the first screening plate.
[0016] The above technical solution is adopted: by setting a fixing plate and fixing it to the first screening plate through a universal joint, it is convenient to fix the first screening plate and will not cause the first screening plate to be blocked and unable to vibrate.
[0017] Furthermore, a universal joint is fixedly connected between the second screening plate and the screening frame.
[0018] The above technical solution is adopted: by setting a universal joint to fix the second screening plate and the screening frame, it is convenient to limit the second screening frame within the screening frame.
[0019] Furthermore, the first screening plate has an opening, and the fixing rod is slidably connected to the opening on the screening frame.
[0020] The above technical solution is adopted: by opening a hole in the first screening plate, it is avoided to block the fixing rod during use.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, the first screening plate vibrates under the drive of the transmission assembly, initially screening the material. Simultaneously, it drives the fixed rod, the actuating block, and other components, causing the second screening plate to vibrate as well. The bottom of the fixed rod is fixedly connected to the transmission plate, and the sliding rod at the bottom of the transmission plate slides, causing the transmission plate to shake, which in turn causes the first screening plate to vibrate. The vibration of the first screening plate then causes the actuating block on the fixed rod to strike the second screening plate. The second screening plate achieves preliminary filtration of the material and can disperse the material. This multi-stage screening method solves the problems of uneven feeding and incomplete single screening in the existing technology, which result in a lot of impurities in the undersize material and poor product quality. It can separate materials according to particle size requirements and meet the strict requirements of high-end product production for raw material purity. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figures 1-4 As shown, this utility model provides a technical solution: a high-efficiency and energy-saving vibrating screen, comprising:
[0033] Screening frame 1, with a feed inlet 4 fixedly connected to the top of the screening frame 1, and a connecting rod 11 fixedly connected to the bottom of the screening frame 1;
[0034] Transmission assembly 2 is placed inside screening frame 1. Transmission assembly 2 includes a first screening plate 21 slidably connected inside screening frame 1. A fixed rod 27 is slidably connected to the first screening plate 21. A transmission plate 25 is fixedly connected to the bottom of the fixed rod 27. A second sliding rod 24 and a first sliding rod 23 are slidably connected to the bottom of the transmission plate 25. Transmission rods 22 are fixedly connected to both the second sliding rod 24 and the first sliding rod 23. Transmission plate 25 is fixedly connected to the first screening plate 21. A fixed frame 28 is fixedly connected to the fixed rod 27. A toggle block 29 is fixedly connected to the fixed frame 28. A second screening plate 210 is slidably connected to the toggle block 29.
[0035] The shock absorber 3 is placed inside the screening frame 1, and a damper 32 is fixedly connected to the shock absorber 3.
[0036] In this invention, the first screening plate 21 vibrates under the drive of the transmission assembly 2, initially screening the material. At the same time, it drives the fixed rod 27, the actuating block 29, and other components, causing the second screening plate 210 to vibrate as well. The bottom of the fixed rod 27 is fixedly connected to the transmission plate 25. The sliding rod at the bottom of the transmission plate 25 slides and drives the transmission plate 25 to shake, which in turn causes the first screening plate 21 to vibrate. The vibration of the first screening plate 21 then strikes the second screening plate 210 through the actuating block 29 on the fixed rod 27. The second screening plate 210 achieves preliminary filtration of the material and can disperse the material. This multi-stage screening method solves the problems of uneven feeding and incomplete screening in the existing technology, which result in a lot of impurities in the undersize material and poor product quality. It can separate materials according to particle size requirements and meet the strict requirements of high-end product production for raw material purity.
[0037] Furthermore, such as Figures 1 to 4 As shown, the second sliding rod 24 and the first sliding rod 23 are respectively fixedly connected to the two ends of the transmission rod 22. The screening frame 1 is fixedly connected to the mounting frame 31, and the damping 32 is fixedly connected to the mounting frame 31. When in use, the motor is installed in the mounting groove on the screening frame 1 and fixed to the damping rod 3. By setting the damping 32, the damping rod 3 can be used to dampen the motor and prevent the motor from falling off.
[0038] A mounting groove is provided on the side of the screening frame 1 near the transmission rod 22. An opening is provided in the mounting groove on the screening frame 1. The transmission rod 22 is slidably connected in the opening on the screening frame 1. The mounting groove on the screening frame 1 facilitates the installation of the motor.
[0039] A sliding groove is provided at the bottom of the transmission plate 25. The first sliding rod 23 and the second sliding rod 24 are slidably connected in the sliding groove at the bottom of the transmission plate 25. By providing a sliding groove at the bottom of the transmission plate 25, it is convenient to guide the sliding of the first sliding rod 23 and the second sliding rod 24 during use. The length of the second sliding rod 24 is twice that of the first sliding rod 23. When the first sliding rod 23 and the second sliding rod 24 slide at the bottom of the transmission plate 25, the transmission plate 25 will shake.
[0040] A fixing plate 26 is fixedly connected to the screening frame 1, and a universal joint is fixedly connected to the fixing plate 26. The universal joint on the fixing plate 26 is fixedly connected to the first screening plate 21. By setting the fixing plate 26 to be fixed to the first screening plate 21 through the universal joint, it is convenient to fix the first screening plate 21 and will not allow the first screening plate 21 to be blocked and unable to vibrate.
[0041] A universal joint is fixedly connected between the second screening plate 210 and the screening frame 1. By setting a universal joint to fix the second screening plate 210 and the screening frame 1, it is convenient to limit the second screening frame 1 within the screening frame 1.
[0042] The above solution also has the problem that the connection method between the fixing rod 27 and the first screening plate 21 is not clear, such as... Figures 2 to 4 As shown, the first screening plate 21 has an opening, and the fixing rod 27 is slidably connected to the opening on the screening frame 1. By having an opening on the first screening plate 21, the fixing rod 27 is prevented from being pressed against during use.
[0043] The working principle provided by this utility model is as follows: Figures 1 to 4 As shown:
[0044] Before use, install the motor in the mounting slot on the screening frame 1, and fix the output end of the motor to the transmission rod 22.
[0045] In use, by starting the motor, the electric transmission rod 22 rotates, causing the second sliding rod 24 and the first sliding rod 23 to slide at the bottom of the first screening plate 21, which in turn causes the first screening plate 21 to vibrate. During this process, the first screening plate 21 and the transmission plate 25 will cause the fixed rod 27 to vibrate. The actuating block 29 is used to strike the second screening plate 210, which achieves preliminary filtration of the material and can disperse the material.
[0046] The vibration force generated by the motor during operation is transmitted to the damper 32 through the damping rod 3, and the damper 32 is used to achieve the vibration reduction effect of the motor.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced.
