Description
Technical Field
[0001] The utility model relates to the technical field of screening, in particular to a vibration screening device. Background Art
[0002] Vibration screening is a device that uses vibration for screening. It makes the material move on the screen surface through vibration and separates the material according to factors such as particle size, specific gravity, magnetism, etc. Vibration screening can be divided into electromagnetic linear vibrating screen and electric circular vibrating screen according to the working principle. The vibration screening machine is composed of a frame, a vibration mechanism, a bed, a screen, a discharge hopper and a press support. The vibration motor drives the bed to vibrate, so that the material moves from top to bottom along the inclined screen surface, and is separated by each layer of screen to meet the process requirements of the screened material. Most traditional vibration screening machines use bolts or welding to fix the screen and the screening box. When dealing with screening conditions of different sizes, it is not only difficult to quickly replace the screen of the vibration screening machine, but even the screening device needs to be replaced, which greatly reduces the screening efficiency and needs to be improved. Utility Model Content

[0005] Preferably, a card slot is provided on the surface of the fixing frame, and a card block is fixedly installed on the surface of the sieve plate, and the card slot is adapted to the card block. Here, when fixing the sieve plate, it is necessary to first slide the card block on the surface of the sieve plate into the card slot on the surface of the fixing frame. When the card block fits into the card slot, the sieve plate can be effectively limited, so that the fixing frame is more stable during vibration and is not easy to fall off, and it also provides a reference for installing the sieve plate.
[0006] Preferably, the depth of the groove is equal to the thickness of the sieve plate. Here, when the sieve plate is installed, it will fit in the groove, and the depth of the groove is equal to the thickness of the sieve plate, so that the sieve plate can be fixed just right. After turning the clamping bar, the fixing frame and the sieve plate can be fixed stably with bolts. When cleaning or replacing the sieve plate, the bolts can be directly unscrewed and the clamping bar can be turned to remove the sieve plate.
[0007] Preferably, the number of the springs is four groups, and the four groups of springs are symmetrically distributed at the four corners of the sieve plate. Here, the four groups of springs are fixed to the four corners of the fixed frame. When the vibration motor is started, the fixed frame starts to vibrate and the objects on the surface of the sieve plate begin to be screened. The springs can increase the frequency of the fixed frame vibration and further speed up the objects passing through the sieve plate.
[0008] Preferably, a support foot is fixedly installed at the bottom end of the base. Here, the screening device may shake when working, and the support foot installed at the bottom end of the base allows the screening device to maintain balance during use, thereby improving the safety of the screening device.
[0009] Preferably, a slide groove is provided on the surface of the base, a slide bar is slidably connected inside the slide groove, a limit plate is fixedly installed on the surface of the slide bar, and a collection box is placed on the surface of the limit plate. Here, the screened objects pass through the inside of the box and slide into the collection box at the bottom.

[0010] Preferably, a handle is fixedly mounted on the surface of the limit plate, and the collection box is located directly below the discharge port. Here, the installation of the handle can facilitate personnel to pull out the limit plate, and the collection box is placed directly below the discharge port, which can facilitate the collection of the screened objects and prevent them from being scattered to other places and inconvenient to clean up.

[0012] 1. In the utility model, a base, a bracket, a box body, a fixed frame, a screen plate, a card strip, a bolt, a vibration motor, a groove, a card block, a card slot, and a discharge port structure are provided. The card block on the surface of the screen plate fits with the card slot on the surface of the fixed frame to limit the screen plate. Another point of the screen plate is fixed by a rotatable card strip and a bolt. The groove can also further limit the screen plate, so that the installation of the screen plate is more stable. When disassembling and maintaining or replacing screen plates of different sizes, it is only necessary to unscrew the bolts and turn the card strip to a horizontal position. The screen plate is easy to replace, which greatly improves the screening efficiency. By providing a fixed block and a spring structure, four groups of springs are fixed at the four corners of the fixed frame. When the vibration motor is started, the fixed frame starts to vibrate, and objects on the surface of the screen plate start to be screened. The spring can increase the frequency of vibration of the fixed frame, further accelerating the passage of objects through the screen plate.
[0013] 2. In the utility model, by arranging supporting feet, sliding grooves, sliding bars, limiting plates, collecting boxes and handle structures, the screening device will shake when working. The supporting feet installed at the bottom of the base enable the screening device to maintain balance when in use, thereby improving the safety of the screening device. The screened objects pass through the inside of the box and slide into the collecting box at the bottom. The collecting box can be quickly pulled out from the bottom by pulling the limiting plate, which is convenient for personnel to unload materials and improves the screening work efficiency. Installing a handle can facilitate personnel to pull out the limiting plate. The collecting box is placed just below the discharge port, which can facilitate the collection of screened objects and prevent them from being scattered to other places and inconvenient to clean.
