Abstract
The utility model relates to a screen, and particularly relates to a vibrating screen. The vibrating screen comprises a hopper, a hopper cover and a frame. The hopper cover is covered onto the hopper. One side of the hopper cover is connected with the hopper through a hinge, and the other sides of the hopper cover and the hopper are provided with opposite holes. The hopper is connected with the frame through a hard spring. The lower part of the hopper is provided with an oscillating pump. The hopper is internally provided with a screen mesh and the bottom of the hopper is provided with a discharge port. According to the technical scheme of the utility model, the hard spring is adopted as a bracing frame for the hopper. Therefore, not only the stability of the hopper is ensured, but also the elasticity of the hopper is ensured at the same time. The vibration efficiency is improved. The hopper and the hopper cover are connected through the hinge, so that the covering process of the hopper cover is facilitated. Therefore, the vibrating screen is convenient to use.
Description
Technical field
The utility model relates to a kind of sieve, is specifically related to a kind of vibratory sieve.
Background technology
Vibratory sieve is to utilize type vibration and the work of revolving of answering that oscillator exciting produces.The upper rotation weight of oscillator makes compass screen surface produce plane whirling vibration, and lower rotation weight makes compass screen surface produce conical surface rotary vibration, and its symphyogenetic effect makes compass screen surface generation revolve again type vibration.Its oscillation trajectory is the space curve of a complexity.This curve is projected as a circle at horizontal plane, and is projected as an ellipse on vertical plane.Regulate the exciting force of upper and lower rotation weight, can change amplitude.And regulate the space phase angle of upper and lower weight, can change the curve shape of compass screen surface movement locus and change the movement locus of material on compass screen surface.The lid of existing vibratory sieve is separated often with hopper, and the speed at every turn covering is slower, and hopper is arranged on guide rail, and the efficiency of vibration is poor.
Utility model content
For solving the above-mentioned shortcoming of prior art, the utility model provides a kind of vibratory sieve, has improved the efficiency of bolting, has facilitated covering of hopper and hopper cover.
The utility model is achieved through the following technical solutions:
A kind of vibratory sieve, comprise hopper, hopper cover and frame, hopper cover covers on hopper, one side of hopper cover is passed through gemel connection, opposite side hopper is provided with relative hole with hopper cover, and described hopper is connected with frame by hard spring, and hopper bottom is provided with oscillating column pump, in hopper, be provided with screen cloth, feed hopper bottom is provided with discharging opening.
Described hopper upper diameter is greater than lower diameter.
The beneficial effects of the utility model: the utility model, by using hard spring as the bracing frame of hopper, can guarantee the stability of hopper, also has good elasticity, vibration efficiency is improved, make to connect with hinge hopper and hopper cover, be convenient to covering of hopper cover, facilitated use.
Accompanying drawing explanation
Fig. 1 is Structure of Vibrating Screen figure.
The specific embodiment
A kind of vibratory sieve, comprise hopper 2, hopper cover 1 and frame 5, hopper cover 1 covers on hopper 2, one side of hopper cover 1 connects by hinge 9, opposite side hopper is provided with relative hole 4 with hopper cover, and described hopper 2 is connected with frame 5 by hard spring 6, and hopper 2 bottoms are provided with oscillating column pump 8, in hopper 2, be provided with screen cloth 3, hopper 2 bottoms are provided with discharging opening 7.
Described hopper 2 upper diameter are greater than lower diameter.Preferably, the hopper diameter on screen cloth top is greater than the diameter of screen cloth bottom hopper, has both alleviated the overall weight of hopper, in the situation that does not increase oscillating column pump power, is issued to good vibrating effect, also can improve the screening efficiency of screen cloth.
Claims (2)
1. a vibratory sieve, comprise hopper, hopper cover and frame, hopper cover covers on hopper, it is characterized in that: a side of hopper cover is passed through gemel connection, opposite side hopper is provided with relative hole with hopper cover, and described hopper is connected with frame by hard spring, and hopper bottom is provided with oscillating column pump, in hopper, be provided with screen cloth, feed hopper bottom is provided with discharging opening.
2. a kind of vibratory sieve according to claim 1, is characterized in that: described hopper upper diameter is greater than lower diameter.
