Problems solved by technology

Furthermore, when adjusting the direction angle of the biaxial vibrator, it is necessary to open the vibrator and disassemble the ring gear, which is extremely inconvenient, and it is very easy to make mistakes when the user adjusts it by himself.

Embodiment 1

[0029] Embodiment 1: as figure 1 As shown, a single-axis linear motion track exciter includes a vibration box 1, a base 2, an exciting spring 4 and an exciting shaft 3, and the exciting shaft 3 is arranged on the vibration box 1; the exciting spring 4 is set On the four corners between the vibration box 1 and the base 2.

[0030] The vibration box 1 is provided with two pairs of rail-fixing rods, and each pair of rail-fixing rods is symmetrically arranged on both sides of the vibration box 1 (the rail-fixing rod 7 is a fixed rod whose length is stretchable and non-adjustable), and is located on the same side of the vibration box 1. The rail-fixing rods 7 on the top are arranged symmetrically with the longitudinal line where the fixed axis of the excitation shaft 3 is located.

[0031] The upper end of the track rod 7 is hinged on the vibrating box 1, and the lower end is hinged on the base 2. The base 2 is provided with a base 5, the base 5 is provided with an arc-shaped slo...

Embodiment 2

[0034] Embodiment 2: as figure 2 As shown, three pairs of rail-fixing rods are arranged on the vibration box 1, and each pair of rail-fixing rods is symmetrically arranged on both sides of the vibration box 1 (the rail-fixing rod 7 is a telescopic rod with adjustable length, and the telescopic rod includes two sections of threads Screw mandrels in opposite directions and a screw sleeve (9) that connects the two sections of screw mandrels together;

[0035] The rail-fixing rod 7 upper end screw sleeve 9 that is in the middle position among the rail-fixing rods 7 on the same side of the vibration box 1 is arranged on the longitudinal line where the excitation axis 3 is fixed, and the other rail-fixing rods 7 are located on the axis of the excitation shaft. 3 The longitudinal line where the fixed axis is located is arranged symmetrically. All the other are with embodiment 1.

Embodiment 3

[0036] Embodiment 3: as image 3 As shown, the vibrating box 1 is provided with four pairs of rail-fixing rods, and each pair of rail-fixing rods is arranged symmetrically on both sides of the vibration box 1 (the rail-fixing rod 7 is a telescopic rod whose length is telescopic and adjustable, and the telescopic rod includes two sections The screw mandrel that screw thread direction is opposite and this two section screw mandrels are connected together a screw sleeve 9);

[0037] The rail-determining rods 7 on the same side of the vibrating box body 1 are arranged symmetrically with the longitudinal line where the fixed axis of the excitation shaft 3 is located. All the other are with embodiment 1.

Abstract

The invention discloses a single-axis linear movement trace vibration exciter, which comprises a vibration box, a base, a vibration exciting spring and an eccentric shaft. The eccentric shaft is arranged on the vibration box, the vibration exciting spring is arranged between the vibration box and the base, more than two trace determination rod pairs are arranged on the vibration box, each trace determination rod pair includes two trace determination rods symmetrically arranged on two sides of the vibration box, the upper ends of the trace determination rods are hinged onto the vibration box, the lower ends of the trace determination rods are hinged onto the base, and the trace determination rods are uniformly inclined and arrayed. The single-axis linear movement trace vibration exciter has the remarkable advantages that by the design of the trace determination rods, the circumferential movement trace of the single-axis vibration exciter is changed into a linear movement trace, and vibration exciting effect and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of vibrating machinery, in particular to an exciter assembly used in vibrating screens and feeders in mining machinery, and more specifically to a single-axis linear motion track exciter. Background technique [0002] In the crusher industry, the vibrating screen or the feeder, which use a single shaft as the exciter, is the most typical structure and the most widely used model. [0003] The motion trajectory generated by the single-axis vibrator is a circle, and the circular motion trajectory has both normal and tangential vibration components. The advantage of this is that critical materials are not easy to block holes on the screen. However, after the circular motion is combined with the spring motion in the vibrating box, the original motion trajectory is changed. The direct result is that the material only has up and down screening motion, but no horizontal conveying motion (very small horizontal compon...
