Wedge block of vibrating screen

Abstract

A vibrating screen wedge relates to the technical field of vibrating screens. The wedge block is pressed on the screen plate, a rack is machined on the wedge block, the upper portion of the rack is connected with a gear in a meshed mode, a transmission shaft is arranged in the center of the gear, the transmission shaft penetrates through a through hole formed in the screen frame and then is connected with a balancing weight in a clearance fit mode, and the balancing weight is connected with the transmission shaft through a set screw and is of an L-shaped structure formed by a balancing weight arm A and a balancing weight arm B; the balancing weight is located on one side of the thick end face of the wedge. The utility model has the beneficial effects that the balancing weight also plays a role of a wrench when the sieve plate is mounted and dismounted, other tools are not needed, the sieve plate is pressed by the wedge block by rotating the balancing weight, driving the rack and the wedge block to move by the gear, and the sieve plate is prevented from falling off due to the effect of the balancing weight when the sieve plate vibrates. A gap generated between the wedge block and the sieve plate is compensated by slight rotation of the balancing weight, the sieve plate cannot be loosened, and the balancing weight also enables the wedge block to generate a certain pre-tightening force on the sieve plate.

Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screen equipment, in particular to a vibrating screen wedge. Background Art

[0002] The vibrating screen installs the screen plate in the screen frame through wedges. Due to processing errors, gaps and high-frequency vibrations, the wedges will withdraw from the wedge mouths after the screen plate vibrates for a period of time, and the screen plate will become loose, requiring the operator to re-tighten the wedges. Utility Model Content

[0003] In order to solve the current problem of loosening of a vibrating screen plate, the utility model provides a vibrating screen wedge.

[0004] The technical solution provided by the utility model is: a vibrating screen wedge, comprising a wedge, the wedge is a long wedge-shaped structure, wherein the thin end face of the wedge is located on the right side and the thick end face is located on the left side, the wedge is pressed on the screen plate, a rack is processed on the top of the wedge, the upper part of the rack is meshed and connected with the gear, a transmission shaft is provided at the center of the gear, the transmission shaft passes through a through hole opened on the screen frame and a connecting counterweight is provided in the gap, the counterweight is connected to the transmission shaft by a set screw, the counterweight is composed of a counterweight arm A and a counterweight arm B to form an L-shaped structure, and the counterweight is located on one side of the thick end face of the wedge.

[0005] When installing the screen plate, after the screen plate is pressed, adjust the counterweight arm A to a horizontal state and the counterweight arm B to a downward vertical state, and then tighten the set screws.

[0006] The beneficial effects of the utility model are as follows: the counterweight block also acts as a wrench when installing and disassembling the screen plate, and no other tools are required. By rotating the counterweight block, the gear drives the rack, the wedge block moves, and the wedge block presses the screen plate. Due to the action of the counterweight block, when the screen plate vibrates, the gap between the wedge block and the screen plate is compensated by the slight rotation of the counterweight block, and the screen plate will not loosen. The counterweight block also causes the wedge block to exert a certain pre-tightening force on the screen plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In the figure, 1-wedge, 11-thin end face, 12-thick end face, 2-gear, 3-rack, 4-screen plate, 5-screen frame, 6-transmission shaft, 7-counterweight block, 71-counterweight arm A, 72-counterweight arm B, 8-setting screw. DETAILED DESCRIPTION

[0011] like Figures 1 to 3 As shown, a vibrating screen wedge includes a wedge 1, which is a long wedge-shaped structure, wherein the thin end face 11 of the wedge 1 is located on the right and the thick end face 12 is located on the left, the wedge 1 is pressed on the screen plate 4, and a rack 3 is processed on the top of the wedge 1, and the upper part of the rack 3 is meshed and connected with the gear 2. A transmission shaft 6 is provided at the center of the gear 2, and the transmission shaft 6 passes through the through hole opened on the screen frame 5 and is connected with a counterweight block 7 in the gap. The counterweight block 7 is connected to the transmission shaft 6 by a fixing screw 8. The counterweight block 7 is composed of a counterweight arm A71 and a counterweight arm B72 to form an L-shaped structure, and the counterweight block 7 is located on the side of the thick end face 12 of the wedge 1.

[0012] When installing the sieve plate 4 , after the sieve plate 4 is pressed, adjust the counterweight arm A71 to be in a horizontal state and the counterweight arm B72 to be in a downward vertical state, and then tighten the set screw 8 .

[0013] The counterweight block 7 also acts as a wrench when installing and removing the screen plate 4. No other tools are needed. By rotating the counterweight block 7, the gear 2 drives the rack 3, the wedge block 1 moves, and the wedge block 1 presses the screen plate 4. Due to the action of the counterweight block 7, when the screen plate 4 vibrates, the gap between the wedge block 1 and the screen plate 4 is compensated by the slight rotation of the counterweight block 7, and the screen plate 4 will not loosen. The counterweight block 7 also causes the wedge block 1 to exert a certain pre-tightening force on the screen plate 4.
