Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a novel vibrating screen excitation beam. Background Technique

[0002] The excitation beam is a cross beam on a linear vibrating screen for installing an exciter. The exciter is installed on the excitation beam through bolts, and the excitation beam is installed on the vibrating screen through flanges at both ends. During operation, the exciter drives the vibrating screen to vibrate through the excitation beam, so as to screen and convey materials. In the operation of the vibrating screen, two exciters are usually provided, and they are connected through a transmission shaft to achieve synchronous operation. This connection method allows the two exciters to be driven by a motor, enabling them to cooperate and produce the required vibration effect. The function of the transmission shaft is to transmit power and torque, ensuring that the two exciters can vibrate at the same frequency and amplitude, so as to realize the effective screening.

[0003] At present, for different types of vibrating screens, the installation positions of the exciters on the excitation beam are also different (the distances between the two exciters are different). However, the existing exciters are installed on the excitation beam by means of bolt connection, and the position of the exciter cannot be adjusted after installation. Therefore, accurate measurement of the installation position of the exciter is required during installation; in addition, when the exciter is not installed in place, the positions of the two exciters cannot be quickly readjusted, which will also cause the distance between the two exciters not to match the connecting shaft, thus reducing the work efficiency and being inconvenient to use.

The inner side surfaces corresponding to the upper surface of the installation sliding sleeve and the cross beam are provided with anti-loosening holes, and fastening ribs are inserted into the anti-loosening holes. A screw rod for driving the two installation sliding sleeves to move in opposite directions is arranged on the side surface of the cross beam, and a nut seat threadedly connected with the screw rod is arranged on the installation sliding sleeve.

The corresponding inner side surfaces of the mounting sliding sleeve 4 and the upper surface of the cross beam 1 are provided with anti-loosening holes 42, and fastening ribs 5 are inserted into the anti-loosening holes 42. A screw rod 6 for driving the two mounting sliding sleeves 4 to move in opposite directions is arranged on the side surface of the cross beam 1, and a nut seat 7 threadedly connected to the screw rod 6 is arranged on the mounting sliding sleeve 4. After mounting the exciter on the mounting sliding sleeve 4, rotate the screw rod 6. During the rotation of the screw rod 6, the nut seat 7 is driven to move, and the nut seat 7 drives the mounting sliding sleeve 4 to slide on the cross beam 1, thereby adjusting the positions of the two exciters and keeping the two exciters always in symmetric positions on the cross beam 1.

[0019] Further, connection flanges 2 are arranged at both ends of the cross beam 1 for mounting the cross beam 1 to an external vibrating screen.

[0025] During use:

[0026] Mount the exciter on the mounting sliding sleeve 4, and use an external wrench to screw the driving nut 62. The driving nut 62 drives the screw rod 6 to rotate. During the rotation of the screw rod 6, the nut seat 7 is driven to move, and the nut seat 7 drives the mounting sliding sleeve 4 to slide on the cross beam 1, thereby adjusting the positions of the two exciters and keeping the two exciters always in symmetric positions on the cross beam 1;

[0027] After the positions of the exciters are adjusted, in order to prevent vibration between the mounting sliding sleeve 4 and the cross beam 1 during the operation of the exciter, just use a hammer to knock the fastening rib 5 into the anti-loosening hole 42.
