Description

Technical Field

[0001] This application relates to the technical field of material screening, and particularly to a vibrating screen. Background Art

[0002] Vibrating screens are commonly used for material screening to achieve the separation of material particles. A vibrating screen operates by the reciprocating spiral vibration generated by a vibrator.

[0003] As shown in the Figure 1 drawing, the vibrating screen includes a screen plate 2 fixedly installed in a trough 1. A plurality of cross beams 3 are also fixedly installed in the trough 1 at intervals. The cross beams 3 are horizontally arranged. A plurality of connecting plates 5 are vertically fixed on the upper surface of the cross beams 3. The plurality of connecting plates 5 are parallel to each other and maintain a certain interval. The upper surface of the connecting plate 5 is fixedly connected to the screen body.

[0004] In the related art, since the cross beams are horizontally arranged, during the material screening process, as the material will fall on the cross beams, it is easy to cause the screen mesh above the cross beams to be blocked by the material, which is not conducive to the material sliding off the screen mesh. Utility Model Content

[0005] In order to facilitate the screening of materials and reduce the blockage of the screen mesh above the cross beams, this application provides a vibrating screen.

[0006] A vibrating screen provided by this application adopts the following technical solutions:

[0007] A vibrating screen includes a plurality of cross beams installed in a trough. The plurality of cross beams are installed in the trough at intervals. A screen plate is installed above the cross beams. Four sides of each cross beam are inclined and arranged below the screen plate. A plurality of sleeve plates are sleeved on each screen plate. The plurality of sleeve plates are arranged at intervals along the length direction of the cross beam. Connecting plates are fixedly installed on the sleeve plates. The connecting plates are arranged perpendicular to the length direction of the cross beam. The upper side of the connecting plate is fixedly connected to the screen plate.

[0008] By adopting the above technical solutions, the sides of the cross beams are inclined, so that the material passing through the screen plate can slide down along the inclined surface of the cross beam surface. The sleeve plates are installed on the cross beams, which facilitates the fixed connection between the connecting plates and the cross beams. The connecting plates and the cross beams are perpendicular to each other, which provides stable support for the screen plate and ensures that the material can fall from the screen plate, and it is not easy to block the screen mesh.

[0009] Optionally, a flat surface portion parallel to the screen plate is provided on one side of each sleeve plate close to the connecting plate.

[0010] By adopting the above technical solutions, the flat surface portion further improves the connection stability between the connecting plate and the cross beam, and facilitates the fixed connection between the connecting plate and the sleeve plates on different cross beams.

[0011] Optionally, two inclined surfaces are further provided on one side of each of the said template plates close to the connecting plate, the flat surface is located between the two inclined surfaces, and the inclined surfaces are gradually inclined from the side close to the flat surface to the side away from the flat surface.

[0012] By adopting the above technical solution, the inclined surfaces further facilitate the downward sliding of the material and reduce the accumulation of the material on the sieve plate.

[0013] Optionally, the connecting plate includes a first connecting portion and a second connecting portion. The first connecting portion is vertically fixed on one side of the second connecting portion. The first connecting portion is parallel to the template plate, and a fixing component is provided between the first connecting portion and the template plate. The second connecting portion is fixedly connected to the flat surface portion.

[0014] By adopting the above technical solution, the fixing component further facilitates the fixation between the connecting plate and the template plate. The first connecting portion is parallel to the side of the template plate and abuts against the template plate under the action of the fixing component, and the second connecting portion plays a supporting role for the template plate.

[0015] Optionally, the fixing component includes a through rod fixed on one side of the template plate close to the first connecting portion. A through hole is provided on the first connecting portion. The through rod is inserted into the through hole. A receiving groove is provided on the side of the through rod away from the template plate. A spring is fixed in the receiving groove. One end of the spring away from the receiving groove is fixed with a clamping block. The clamping block is slidably connected to the receiving groove and extends in the direction away from the receiving groove. When the through rod is inserted into the through hole, the clamping block abuts against the first connecting portion.

[0016] By adopting the above technical solution, when installing the connecting plate and the template plate, the through rod is inserted in the direction close to the through hole. At this time, the clamping block retracts into the receiving groove. When the first connecting portion abuts against the side wall of the template plate, the clamping block abuts against the side of the first connecting portion away from the template plate, realizing the rapid fixation between the connecting plate and the template plate.

[0017] Optionally, the clamping block is provided with an inclined surface that gradually inclines upward from the side close to the receiving groove to the side away from the receiving groove.

[0018] By adopting the above technical solution, during the process of inserting the through rod into the through hole, under the action of the inclined surface of the clamping block, the clamping block gradually retracts into the receiving groove. When the first connecting portion abuts against the template plate, the clamping block pops out under the action of the spring, realizing the limit fixation of the first connecting portion.

[0019] Optionally, an installation component is provided between the connecting plate and the sieve plate to facilitate the rapid installation and fixation of the two.

[0020] By adopting the above technical solution, the installation component fixedly connects the connecting plate and the sieve plate, further facilitating the rapid installation and fixation of the sieve plate and the connecting plate.

[0021] Optionally, the installation component includes a fixing plate fixed on the trough body. On the side of the fixing plate close to the sieve plate, an installation plate is fixed. The installation plate is located above the sieve plate. A bolt is threadedly installed on the installation plate, and the bolt passes through the sieve plate and is threadedly connected to the second connecting portion.

[0022] By adopting the above technical solution, the fixing plate limits the sieve plate, reducing the limitation of the sieve plate in the horizontal direction. The bolt installed on the installation plate further improves the connection stability between the sieve plate and the connecting plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

Detailed implementation mode

[0034] The following will further describe the present application in detail with reference to the attached Figure 2-6 drawings.

[0035] An embodiment of the present application discloses a vibrating screen.

[0036] Embodiment 1

[0037] Referring to Figure 2 , a vibrating screen includes a horizontally arranged trough body 1, a sieve plate 2 is installed on the trough body 1, and an exciter for vibrating and screening the sieve plate 2. A plurality of horizontally arranged cross beams 3 are also fixed in the trough body 1. Both ends of the cross beam 3 are fixed to the inner wall of the trough body 1. The plurality of cross beams 3 are arranged at intervals along the length direction of the trough body 1. The sides of the cross beam 3 are all inclined and arranged below the sieve plate 2, so that the material passing through the sieve plate 2 can slide downward along the inclined side of the cross beam 3, reducing the accumulation and blockage of the material on the sieve plate 2.

[0038] Referring to Figure 3 , a plurality of sleeve plates 4 are fixedly arranged at intervals on each cross beam 3. Openings 41 are formed on the sleeve plates 4. The sleeve plates 4 are sleeved with the cross beam 3 through the openings 41. The upper sides of the sleeve plates 4 are all provided with flat portions 42. The flat portions 42 are parallel to the sieve plate 2. The sleeve plates 4 on the adjacent cross beams 3 are arranged oppositely.

[0039] A plurality of connecting plates 5 arranged at intervals are also installed on the cross beam 3. The connecting plates 5 are parallel to each other. The connecting plates 5 are perpendicular to the cross beam 3, and the connecting plates 5 are fixed on the sleeve plates 4 to realize the supporting effect on the sieve plate 2.

[0040] The connecting plate 5 includes a first connecting portion 51 and a second connecting portion 52. The first connecting portion 51 is perpendicular to the second connecting portion 52. When the first connecting plate 5 abuts against the side of the sleeve plate 4, the second connecting portion 52 is located above the sleeve plate 4. Fixing assemblies 6 are arranged between the connecting plate 5 and the sleeve plate 4. The connecting plate 5 and the sleeve plate 4 are quickly fixed and installed through the fixing assemblies 6.

[0041] The fixing assembly 6 includes a through rod 61 horizontally fixed on the sleeve plate 4. A perforation 511 is formed through the first connecting portion 51. The through rod 61 is arranged opposite to the perforation 511 and is inserted into each other. When the through rod 61 is inserted into the perforation 511, the second connecting portion 52 is located directly above the flat portion 42.

[0042] Reference Figure 4 , on the side of the rod 61 away from the sleeve plate 4, a receiving groove 611 is formed. The axis of the receiving groove 611 is parallel to the sleeve plate 4. A spring 612 is fixed in the receiving groove 611. One end of the spring 612 is fixedly connected to the bottom wall of the receiving groove 611. A clamping block 613 is fixed at the end of the spring 612 away from the bottom wall of the receiving groove 611. The clamping block 613 is slidably connected to the receiving groove 611. The clamping block 613 has an inclined surface that gradually slopes upward from the side close to the receiving groove 611 to the side away from the receiving groove 611. When the rod 61 is inserted into the through hole 511, under the action of the inclined surface, the clamping block 613 gradually retracts into the receiving groove 611. When the first connecting portion 51 abuts against the sleeve plate 4, the clamping block 613 abuts against the first connecting portion 51, so that the first connecting portion 51 is located between the clamping block 613 and the sleeve plate 4.

[0043] Reference Figure 2 and Figure 5 , the sieve plate 2 is located above the second connecting portion 52. An installation assembly 7 is provided between the sieve plate 2 and the second connecting portion 52. The sieve plate 2 and the second connecting portion 52 are fixedly connected through the installation assembly 7. The installation assembly 7 includes a plurality of fixing plates 71 vertically fixed on the tank body 1. The fixing plates 71 are perpendicular to the length direction of the cross beam 3. An installation plate 72 is fixed on the fixing plate 71. The installation plate 72 extends toward the side close to the sieve plate 2. The installation plate 72 is located above the sieve plate 2. A bolt 73 is threadedly installed on the installation plate 72. The bolt 73 is perpendicular to the installation plate 72. The bolt 73 passes through the sieve plate 2 and is threadedly connected to the second connecting portion 52, so that the sieve plate 2 and the second connecting portion 52 are fixedly connected, improving the connection stability and installation efficiency.

[0044] The implementation principle of Embodiment 1 is as follows: By installing the inclined cross beam 3, the sieve plate 2 on the upper side of the cross beam 3 is not easily blocked. The sleeve plate 4 is fixed on the cross beam 3 to play a supporting role, facilitating the combined action of the connecting plate 5 and the cross beam 3 to support the sieve plate 2. When installing the connecting plate 5, the rod 61 is inserted into the through hole 511, and the first connecting portion 51 is located between the clamping block 613 and the sleeve plate 4, realizing the rapid installation and fixation of the connecting plate 5 and the sleeve plate 4. The sieve plate 2 is fixed through the installation assembly 7, ensuring the screening effect of the sieve plate 2.

[0045] Embodiment 2

[0046] Reference Figure 6 , the difference between this embodiment and Embodiment 1 is that each sleeve plate 4 also has two inclined surfaces 43. The flat surface portion 42 is located between the two inclined surfaces 43. The inclined surfaces 43 both have inclined surfaces that gradually slope downward from the side close to the flat surface portion 42 to the side away from the flat surface portion 42.

[0047] The implementation principle of Embodiment 2 is as follows: The inclined surface portions 43 further facilitate the falling of materials and reduce the accumulation of materials.
