[0036] According to the utility model provides a kind of cleaning screen, as shown in Figures 1 to 4 The cleaning screen in the embodiment includes a welded screen frame 1, screen piece assemblies 3, screen piece partitions 2 and an adjusting assembly. The welded screen frame 1 can connect the components to form a whole structure. The screen piece assemblies 3 can clean the materials. The adjusting assembly can flexibly adjust the inclination angle of the screen piece assemblies 3 to cope with different types of materials or different cleaning requirements. The screen piece partitions 2 can prevent the materials from piling up, which is conducive to improving the material conveying effect. In the following, the specific connection relationship and positional relationship of the components of the cleaning screen according to the utility model will be described in detail.

[0037] In the embodiment, as shown in Figures 1 to 2 The welded screen frame 1 is formed into a cuboid frame structure, which is used to connect the screen piece assemblies 3, screen piece partitions 2 and the adjusting assembly to form a whole. In addition, the cleaning screen is part of a cleaning system, and needs to be connected with other components in the cleaning system. Specifically, the welded screen frame 1 is connected with a screen box (not shown in the figure) to be able to reciprocate with the screen box. The welded screen frame 1 is a conventional component of the existing cleaning screen, and thus its specific structure, specifications and the like will not be described in detail, as long as it can meet the use requirements of the cleaning screen.

[0038] In the embodiment, as shown in Figure 1 and Figure 4As shown, the screen assembly 3 comprises a rotating shaft and a plurality of screen pieces 30 arranged in sequence on the outer side of the rotating shaft. Specifically, each screen piece 30 is formed with screen tooth portions 300 and transition portions 301 arranged alternately, so that each screen piece 30 is formed as a wave-like plate structure, which facilitates the screening effect of the screen piece 30 on the material. It should be noted that the screen piece 30 in the embodiment is fixedly connected with the rotating shaft, but the specific connection manner is not limited, for example, it can be achieved by welding or one-piece forming. In addition, the shape, specification, etc. of the screen tooth portion 300 and the transition portion 301 in each screen piece 30 are not specifically limited, for example, the screen tooth portion 300 and the transition portion 301 are formed as square structures in the embodiment, and the screen tooth portion 300 protrudes from the transition portion 301, as long as the screening effect on the material can be achieved.

[0039] It should be further noted that, in order to more clearly and accurately describe the assembly relationship of each component, the direction of the reciprocating movement of the entire screening sieve along with the screen box is set as the X direction, which is also the direction of the material transportation. In addition, the screening sieve is provided with a plurality of screen assembly 3 as described above, and the plurality of screen assembly 3 is distributed along the X direction. In addition, the extension direction of the screen assembly 3 is set as the Y direction, and obviously, the X direction is perpendicular to the Y direction.

[0040] In addition, in the embodiment, the inclination angle of the screen assembly 3 can be flexibly adjusted to adapt to different types or different screening requirements of the material. Specifically, along the Y direction, a connecting hole 10 is formed at the inner wall of the welded screen frame 1, and the two ends of the rotating shaft of the screen assembly 3 are rotatably connected with the connecting hole 10 (the specific connection manner is not fixed, which belongs to the conventional mechanical means, for example, it can be achieved by bearing, etc.).

[0041] More specifically, as shown in Figure 1 and Figure 4 In order to facilitate the stable assembly of the screen piece partition plate 2 and the adjusting plate 43, the rotating shaft in each screen assembly 3 is formed with a plurality of first bends and a second bend, which are formed as U-shaped structures. The first bend and the second bend are arranged between any two adjacent screen pieces 30. Correspondingly, the rotating shaft is connected with the screen piece partition plate 2 (the first clamping groove 21) through the first bend, and is connected with the adjusting plate 43 (the second clamping groove 430) through the second bend. That is, the number and position of the first bend on each rotating shaft correspond to the screen piece partition plate 2, and the second bend corresponds to the adjusting plate 43 (for example, five screen piece partition plates 2 are arranged in the embodiment, and five first bends are formed on each rotating shaft). In addition, the adjusting plate 43 is arranged at the middle of the Y direction in the embodiment, that is, the second bend is close to the first bend at the middle of the rotating shaft, and the screen piece 30 can not be arranged between them.

[0042] In this embodiment, the tilt angle of the multiple sieve assembly 3 is adjusted by an adjustment component. For example... Figure 2 As shown, the adjustment assembly includes a toothed disc 41 with a fan-shaped structure. The arc-shaped side of the toothed disc 41 has first gear teeth, and the toothed disc 41 is welded and fixed to the welded screen frame 1. The adjustment assembly also includes a handle 40, the end of which is rotatably connected to the toothed disc 41; the handle 40 also has second gear teeth that mesh with the first gear teeth. Further, the adjustment assembly includes a connecting rod 42 and an adjustment plate 43. The extension direction of the adjustment plate 43 is the same as the extension direction of the screen partition 2 (i.e., extending along the X direction). The two ends of the connecting rod 42 are rotatably connected to the adjustment plate 43 and the handle 40, respectively. Thus, when the handle 40 is rotated, the connecting rod 42 can drive the adjustment plate 43 (along the X direction) to swing (the adjustment plate 43 has no contact with the welded screen frame 1 or the screen partition 2), thereby enabling the adjustment plate 43 to drive all screen assembly 3 to rotate synchronously, thereby adjusting the tilt angle of the screen assembly 3.

[0043] It should be noted that the aforementioned gear plate 41 limits the adjustment range of the handle 40 and provides stable support for the handle 40, connecting rod 42, and adjusting plate 43. The specifications of the first and second gears are not fixed and can be determined according to actual needs. Furthermore, the handle 40, connecting rod 42, and adjusting plate 43 can be rotatably connected via pins or other structures; this is a conventional mechanical method and will not be elaborated upon further.

[0044] Furthermore, the bottom of the adjusting plate 43 has a plurality of second slots 430, the number of which corresponds to the number of screen assembly 3. Each second slot 430 is an open, n-shaped structure, allowing it to engage with the second bend. Further, the second slots 430 engage with the second bend in a clearance fit, preferably 0.1mm to 0.2mm, to facilitate the rotation of the screen assembly 3. Further, since the adjusting plate 43 is close to the central screen partition 2, it is difficult to clean if material falls. Therefore, a baffle 431 is formed on the side of the adjusting plate 43 near the central screen partition 2 to prevent material from falling and clogging the adjusting plate 43. In addition, the adjusting plate 43 is also provided with a connecting plate 432 for easy connection with the connecting rod 42.

[0045] In this embodiment, as Figures 1 to 3 As shown, multiple screen partitions 2 are welded to the welded screen frame 1, and the multiple screen partitions 2 are spaced apart along the Y direction. Based on the specific structure of the welded screen frame 1, the first end of the screen partition 2 in the extending direction is formed with a relief recess, and the first end of the screen partition 2 overlaps with the welded screen frame 1 and is welded and fixed through this recess; the second end of the screen partition 2 is directly welded to the welded screen frame 1.

[0046] In the embodiment, the top of the screen partition plate 2 is formed into a sawtooth structure, specifically, the top of the screen partition plate 2 is formed with a plurality of sequentially arranged convex portions 20, each of which is formed into a wedge-shaped structure, and the end face of the convex portion 20 is formed into a right-angled triangle structure along the thickness direction (i.e. Y direction) of the screen partition plate 2; more specifically, in the above-mentioned end face of each convex portion 20, the end face is formed with a first right-angled side, a second right-angled side and an inclined side, the first right-angled side is parallel to the extending direction of the screen partition plate 2, and the length of the first right-angled side is greater than the length of the second right-angled side, so as to make the angle between the inclined side and the first right-angled side (i.e. ∠A) smaller than the angle between the second right-angled side and the inclined side, that is, each convex portion 20 is inclined towards the first end of the screen partition plate 2, and when the cleaning screen is assembled with the screen box, the first end of the screen partition plate 2 is the outlet end of the material. Preferably, ∠A is 20°-30°, and the length of the first right-angled side is 25mm-35mm.

[0047] In addition, similar to the adjusting plate 43, the bottom of the screen partition plate 2 is formed with a plurality of first clamping grooves 21 corresponding to the first bending, and the first clamping grooves 21 and the first bending are formed into a clearance fit.

[0048] According to the cleaning screen of the utility model, the various components are connected by welding the screen frame 1 to form an integral structure, the plurality of screen assemblies 3 can clean the material, the adjusting assembly can flexibly adjust the inclination angle of the screen assembly 3 to cope with different types of materials, further, the screen partition plate 2 is provided with a sawtooth structure at the top, when the cleaning screen moves forward as a whole, the screen partition plate 2 can easily pass through the material layer, when the cleaning screen moves backward as a whole, the screen partition plate 2 can move the material to transport the material, so that the screen partition plate 2 with the sawtooth structure in the application can greatly avoid the accumulation of the material and improve the efficiency of the material transportation.

[0049] Finally, it should be noted that the above-described embodiments are merely specific implementations of the present application, which are used to illustrate the technical solutions of the present application, but not to limit them, and the protection scope of the present application is not limited thereto, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art within the technical range disclosed by the present application can modify or easily think of changes to the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to some technical features; and these modifications, changes or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and all should be covered in the protection scope of the present application.
