The process in which the broken bulk materials are divided into different particle sizes through one or several layers of screen surfaces is called screening. The screen plate is also called a porous plate, which has good wear resistance, long service life, moisture resistance, and good wear resistance. It is suitable for machinery industries such as ore washing, screening, grading, deslagging, demuding, and dehydration.

[0018] The mining screening machine is a vibrating screening machine that utilizes the relative movement between bulk materials and the screen surface to allow some particles to pass through the screen holes, and classifies materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process of the mining screening machine is generally continuous. After the screened raw materials are fed to the screening machine (referred to as the screen), materials smaller than the size of the screen holes pass through the screen holes, which are called undersize products, and materials larger than the size of the screen holes are continuously discharged from the screen surface, which are called oversize products. The process in which the broken bulk materials are divided into different particle sizes through one or several layers of screen surfaces is called screening. The screen plate is also called a porous plate, which has good wear resistance, long service life, moisture resistance, and good wear resistance. It is suitable for machinery industries such as ore washing, screening, grading, deslagging, demuding, and dehydration.

[0019] Traditional screen plates are usually connected by bolts, which requires more time and labor during installation and disassembly, and the bolts may reduce the stability of the screen plate due to wear or loosening.

[0020] Some embodiments of the present application provide a fixing device for fixing a sieve plate, including a sieve surface, a plurality of supporting channel steels 2, and a plurality of positioning channel steels 3;

[0021] The supporting channel steel 2 is transversely fixed on the positioning channel steel 3 to form a sieve plate frame; the sieve surface is composed of a plurality of sieve plates 1 and a supporting portion, and the sieve plates 1 and the positioning channel steel 3 are vertically fixed on the sieve surface respectively; the sieve plate frame is connected to the fixed sieve plate 1 through a slot on the fixed sieve plate 1.

[0022] The sieve plate installation step includes inserting a part of the sieve plate frame into a designed slot and fixing it by physical means (such as pressure, friction, etc.).

[0023] The innovation of this application lies in modifying the size of the sieve plate, designing the shape of the slot, and installing the sieve plate. In order to solve the problem that the traditional bolt connection method is time-consuming and labor-intensive during installation and disassembly, as well as the possible reduction in stability, the size of the sieve plate frame and the slot is designed, the size of the sieve plate is adjusted, and the appropriate slot shape and size are designed according to the size and shape of the sieve plate frame; a part of the sieve plate frame is inserted into the slot of the sieve plate, and fixed by physical means (such as pressure, friction, etc.). The sieve plate slot connection modification method of this application can achieve fast and simple installation and disassembly of the sieve plate, while improving the stability of the sieve plate. By inserting the supporting channel steel 2 into the groove formed by two fixed screen plates, the pressure and friction between the screen plates 1 are used to fix them, and one end of the screen plate can be effectively adjusted up and down and moved, which can increase the efficiency of the screen plate in screening mine materials and also increase the practicality of the mine screening machine at work. The screen plate frame is driven to move by rotation, which effectively fixes the adjusted and moving screen plate and controls its movement at any time. The operation is simple, which increases the use and working efficiency of the mine screening machine and meets the user's needs.

[0024] In some embodiments, the sieve plate 1 is a grooved sieve plate, and the supporting channel steel 2 is clamped in the groove formed when every two sieve plates 1 are spliced ​​together.

[0028] like Figures 1 to 3 As shown, the utility model relates to an improved fixing device for fixing a sieve plate, the fixing device for fixing a sieve plate is specially designed to use a grooved sieve plate 1, the size of which is set to 610mm×610mm. Figure 1 As shown, the positioning channel steel 3 is consistent with the slope of the fixed screen plate and is fixed vertically on the screen surface. On this positioning channel steel 3, the supporting channel steel 2 is fixed horizontally to form a screen plate frame. The supporting channel steel 2 is inserted into the groove formed by the splicing of two fixed screen plates, and the pressure and friction between the screen plates 1 are used to achieve fixation. Figure 2As shown, 90-degree angle irons are used on both sides of the modified screen surface, and the sieve plates on both sides are fixed by extrusion to ensure the stability of the sieve plates. Since the sizes of the sieve plates used before and after the modification are different, the size of the screen surface has also changed accordingly. In some embodiments, the length of the positioning channel steel 3 is 200mm, the height of the supporting channel steel 2 is 120mm, the supporting portion of the supporting channel steel 2 is 52mm, the length of the screen surface is 3535mm, the width of the screen surface is 1830mm, and the sieve plate 1 is a groove sieve plate with a length of 610mm at one end and 26mm incisions on both sides of the other end. The height of the sieve plate 1 is 30mm. Multiple sieve plates 1 are spliced ​​together, and a 52-53mm card slot is left at the joint of each two sieve plates 1 to allow the supporting channel steel 2 to be inserted, and the supporting channel steel 2 is fixed to the positioning channel steel 3 at the same time.

[0029] This slot connection method allows for quick and easy installation and removal of the screen plate while improving the stability of the screen plate.

[0030] By inserting the supporting channel steel 2 into the groove formed by two fixed screen plates, the pressure and friction between the screen plates 1 are used to fix them, and one end of the screen plate can be effectively adjusted up and down and moved, which can increase the efficiency of the screen plate in screening mine materials and also increase the practicality of the mine screening machine at work. The screen plate frame is driven to move by rotation, which effectively fixes the adjusted and moving screen plate and controls its movement at any time. The operation is simple, which increases the use and working efficiency of the mine screening machine and meets the user's needs.
