Embodiment 1

[0041] like figure 1 , 4 , Shown in 5, vibrating screen of the present invention is mainly made up of screen frame 1, screen cloth 2, grid frame 3, vibrating motor 4, base 5, vibrating spring 6 and vibrating body 7. The grid frame 3 is located in the cavity surrounded by the screen frame 1, and an annular cavity is formed between the grid frame 3 and the screen frame 1. The screen cloth 2 is tightened on the grid frame 3 by stretching hoops 9 . Start the vibrating motor 4, the vibrating body 4 vibrates, the large particle slag remaining on the upper surface of the screen 2 is discharged from the slag discharge port 1.2, and the fine material leaks from the screen.

[0042] In this embodiment, the inner wall of the screen frame 1 and the outer wall of the grid frame 3 are provided with corresponding annular grooves 1.4, and an annular stretching hoop 9 is placed in the annular groove on the screen frame 1, and the outer wall of the screen frame 1 Offer through hole on the to...

Embodiment 2

[0054] Compared with Embodiment 1, in this embodiment, the ends of the stretching hoops 9 are still intersected after passing through the screen frame 1 . The difference from Embodiment 1 is that in this embodiment, the stretching net hoop 9 is tightened by straight pulling. like Image 6 As shown, the locking buckle 13 is fixed at the end of the stretching hoop 9, and the hook 12 is fixed on the outer wall of the screen frame 1. Pull the locking buckle 13 by hand to pull one end of the stretching net hoop 9 forward, hang it on the hook 12 after tightening, and then pull the locking piece of the locking buckle 13 to close the stretching net hoop 9 Tight fix.

[0055] This embodiment does not need tools to tighten, only needs to be pulled by hand, the advantage is that it is faster.

[0056] In the above-mentioned first and second embodiments, the ends of the stretching hoops 9 pass through the screen frame 1 and then intersect to realize the tightening of the screen in the ...

Embodiment 3

[0058] Different from Embodiments 1 and 2, in this embodiment, the hoops 9 of the stretched mesh do not need to pass through the screen frame. like Figure 7 as shown,

[0059] The stretching hoops on the same layer are two semicircles, and the two stretching hoops are correspondingly arranged to form a ring, and the end of one of the stretching hoops is relatively close to the corresponding end of the other stretching hoop. Fix the coupling piece 16 at the end of the stretching net hoop bar 9, penetrate the fastening bolt 14 in the two relative coupling pieces, and set the nut 15 on the fastening bolt 14.

[0060] Open the operation hole 1.3 at the position of the screen frame 1 corresponding to the end of the stretching hoop 9, extend the wrench from the operating hole and twist the nut 15, and the two stretching hoops 9 are relatively tightened, and the screen can be tightened ,No longer. The so-called opening of the operation hole at the position corresponding to the en...

Abstract

The invention discloses a method for quickly replacing a tensioned screen and a vibrating screen, which belong to the technical field of material screening. It includes a screen frame, a net frame, a screen mesh and stretching hoops. The net frame is located in the screen frame, and the feature is that the stretching hoops are placed on the inner wall of the screen frame, and a through hole is opened at the position of the screen frame corresponding to the stretching hoops. , the end of the stretching hoop passes through the through hole; when changing the screen, first place the screen flat on the grid frame, then place the screen frame on the screen and drop it, the screen frame folds the screen down and uses it The screen is applied on the outer wall of the net frame; the ends of the tensioning hoops are connected with a tensioning device, and the stretching hoops are tightened by operating the tensioning device. Since the screen frame and stretching hoops of the present invention have an integrated structure, when replacing the screen, it is only necessary to place the screen flatly on the upper end of the grid frame, and then place the screen frame on the screen and drop it once, relying on the vertical drop of the screen frame The screen can be bent and pasted on the outer wall of the grid frame. There is no need to manually bend the screen, and there is no requirement for the operator's proficiency.

Description

technical field [0001] The invention belongs to the technical field of material screening, and in particular relates to a vibrating screen. Background technique [0002] Enterprises widely use vibrating screens to sort materials. Commonly used vibrating screens include structural components such as screen frames, grid frames, screen meshes, stretching hoops, springs connected to the screen frames, and vibration motors. The screen is vibrated by starting the vibrating motor, so that the small particles pass through the screen and leak down, and the large particles are blocked on the screen. The screen used in the vibrating screen is generally woven with metal wire, nylon wire, etc. The screen is a vulnerable part and needs to be replaced after a period of use. An important factor affecting the use effect of the vibrating screen is whether the screen can be tightened. The tighter the screen is, the better the vibrating screening effect is and the longer the service life is. ...
