Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vibrating screen detection, specifically, and relates to a vibrating screen amplitude detection device. BACKGROUND

[0002] The vibrating screen works by reciprocating and rotating vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, and the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of the two causes the screen surface to produce complex rotary vibration. The vibration trajectory is a complex spatial curve. The curve is projected as a circle on the horizontal plane, and as an ellipse on the vertical plane. Adjusting the excitation force of the upper and lower rotating weights can change the amplitude. Adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface movement trajectory and the movement trajectory of the material on the screen surface. The amplitude of the vibrating screen needs to be detected during use to determine whether the parameters of the vibrating screen meet the requirements.

[0003] Further search found that the authorized announcement No. CN220490223U discloses a vibrating screen temperature and amplitude detection device. Through specific technical structure setting, it actually solves the technical defects that the existing vibrating screen amplitude detection needs to use amplitude cards to be attached to the surface of the vibrating screen and then detected. However, this method needs to be held for a long time, and the amplitude card is attached to the side wall of the vibrating screen, which causes the hands of the operator to be sore and increases the working difficulty of the operator. The technology uses an electromagnet to be attracted to the side wall of the vibrating screen and fixed with the vibrating screen. When the trigger column is displaced to the through hole in the center of the disc, the vibrating screen drives the trigger column to vibrate. The vibrating trigger column acts on the detection column, which drives the detection column to move in the fixed seat. According to the distance of the detection column moving in the fixed seat, the amplitude of the vibrating screen can be detected.

[0004] However, the above-mentioned prior art has many defects in actual use, such as: when detecting the amplitude of the vibrating screen, the amplitude detection device needs to detect different positions of the vibrating screen. The above-mentioned technology can only detect the amplitude of the side wall of the vibrating screen, which limits the use range of the amplitude detection device. UTILITY MODEL CONTENTS

The through holes 201 facilitate the rotation of the rotating rods 3 inside the support shaft frames 2. After rotation, one set of locking holes 301 aligns with the support shaft frame 2, allowing the fixing mechanism 6 to fix the rotating rods 3 inside the support shaft frame 2. A detection component 4 for detecting the amplitude of the vibrating screen is provided between the two sets of rotating rods 3. The detection component 4 includes a mounting ring 401 and a mounting plate 402. The outer walls of the mounting ring 401 are rotatably mounted between two sets of support shafts 2 via rotating rods 3.

Then, the vibration of the vibrating screen drives the trigger rod 502 to vibrate.
