Abstract

A two-axis elliptical box vibrator, belonging to the field of vibrating screening machinery, is designed to address the shortcomings of existing vibrators, such as unsatisfactory screening effects and the impact damage caused by linear motion vibrators to the screening machine. The vibrator has two vibrating shafts, each mounted on the vibrator housing via bearings. Each shaft has one or two eccentric blocks. The two vibrating shafts are connected by gears of equal parameters. The eccentric directions of the eccentric blocks on the two shafts are symmetrical, but their eccentric weights are unequal. Alternatively, the eccentric directions of the eccentric blocks on the two shafts are asymmetrical, but their eccentric weights are equal. Driven synchronously by a single motor, the trajectory is elliptical. Alternatively, the two vibrating shafts can be driven by two motors without gear meshing, resulting in self-synchronized elliptical trajectory operation. It features a compact structure, convenient manufacturing and installation, and can be widely used in vibrating screens with various specifications of elliptical motion trajectories.

Description

Two-axis elliptical box vibrator

Technical field:

The utility model belongs to the field of vibrating screening machinery, and mainly relates to a two-axis elliptical box vibrator applied to vibrating screens.

Background technique:

The box vibrator of the vibrating screen is generally a circular motion track vibrator with one vibration axis, or a linear motion track vibrator with two vibration axes. Because the screening effect of these two vibrators is not ideal, especially the impact damage of the linear motion track vibrator to the screening machine is relatively large. Therefore, there is a need for a box-type vibrator that can have a good screening effect and does not have a large impact on the screening machine.

Invention content:

The purpose of the utility model is to provide a two-axis elliptical box-type vibrator, which operates smoothly and can effectively improve the screening efficiency of the vibrating screen.

The utility model is realized through the following measures, and is mainly composed of a box body, a vibrating shaft and an eccentric block. One or two eccentric blocks are installed on the top. The connection method between the vibration shaft and the motor and the setting method of the eccentric block on the vibration shaft are one of the following three methods: a. The two vibration shafts are meshed with gears with equal parameters and a transmission ratio of 1, and the motor vibrates with one of them. Shaft connection; the eccentric direction of the eccentric block on the two vibrating shafts is symmetrical, and the eccentric weight of the eccentric block is not equal; b. The two vibrating shafts are meshed with gears with equal parameters and a transmission ratio of 1, and the motor is connected to one of the vibrating shafts Connection; the eccentric weights of the eccentric blocks on the two vibration axes are equal, and the eccentric directions are asymmetrical. The angle of the eccentric direction of one of the eccentric blocks from the symmetrical position is greater than 0 degrees and less than 90 degrees; c. The eccentricity of the eccentric blocks on the two vibration axes The weights are not equal, and each vibrating shaft is connected to a motor respectively.

The above method a is driven by a motor, and the two vibrating shafts are forced to run synchronously through gear transmission; since the eccentric weights of the eccentric blocks on the two vibrating shafts are not equal, the vibration track of the vibrator is elliptical. The above method b is driven by a motor, and the two vibrating shafts are forced to run synchronously through gear transmission; because the eccentric directions of the eccentric blocks on the two vibrating shafts are asymmetrical, the vibration track of the vibrator is elliptical. The above method c is that the two motors drive the two vibrating shafts separately and run synchronously; since the eccentric weights of the eccentric blocks on the two vibrating shafts are not equal, the vibrating track of the vibrator is elliptical.

The beneficial effect of the utility model is that the eccentric weights of the eccentric blocks on the two vibrating shafts are not equal, or the eccentric directions of the eccentric blocks are asymmetrical; the box-type vibrator is driven by one motor or two motors, and the forced synchronization Or the self-synchronized transmission mode realizes the elliptical motion track of the vibrator. It has the characteristics of compact structure, convenient manufacturing and installation, and can be widely used in vibrating screens with elliptical motion tracks of various specifications.
