Abstract

The utility model discloses a screening machine which solves the problems that an existing screen machine is small in amount of screening and producing and materials are prone to jam. The screening machine comprises a sieve body (6). A hinge shaft (10) of the sieve body (6) is connected with a supporting spring (11). The sieve body (6) is connected with a main pressure spring (8) which is connected with a vibrating motor (4). Eccentric wheels (1) are arranged on shafts of two sides of the vibrating motor (4). Fastening bolts (3) are connected with eccentric wheels (1) and a motor shaft (2). Protective hoods (5) are arranged outside the eccentric wheels (1). The sieve body (6) is connected with a material inlet (7) and a material outlet (9) and forms a top rake of 12 degrees with the horizontal level. The supporting spring (11) supports the sieve body (6) so that the sieve body is a floating sieve body. The motor which vibrates drives the main pressure spring (8) to vibrate and drives the sieve body (6) to move vertically. Under the action of the top rake, qualified materials are sent to the material outlet from the material inlet and failed materials are screened down the sieve. An eccentric overlap ratio of the two eccentric wheels (1) is used for adjusting vibration strength of the motor so as to suitably screen different materials.

Description

A kind of screening machine

Technical field

The utility model relates to compound fertilizer production equipment, a kind of a kind of screening machine for material screening.

Background technology

In existing production of compound fertilizer technology, generally adopt the reciprocating screen extension set to come classifying granular material, the reciprocating screen extension set is that the cam that uses the sieve nest parallel direction to arrange rotates, so that sieve nest carries out reciprocating, thereby impels granular material to do parallel motion along sieve, simultaneously under the effect of self gravitation, pass through sieve, finish screening work, this screening machine granule materials is to pass through sieve by gravity, and particle is blocked in the sieve mesh easily, the screening amount is little, and output is not high.

Summary of the invention

Be blocked in easily the sieve mesh in order to solve existing screening machine material particles, the screening amount is little, the not high problem of output, the utility model proposes a kind of screening machine, by changing the movement locus of sieve, make sieve from original parallel reciprocal action with sieve, be improved to the mode with the sieve vertically-acting, simultaneously, by adjusting the eccentric wheel angle on the vibration motor, change the vibration amplitude of sieve, make material particles produce the vibrations of vertical sieve, better pass through sieve, thereby address the above problem.

The technical solution of the utility model is: this screening machine comprises the sieve body, the hinge axis of sieve body is connected with support spring, the sieve body is connected with main Compress Spring, main Compress Spring connects vibration motor, on the axle of vibration motor both sides eccentric wheel is installed, tight fixed bolt connecting eccentric wheel and motor shaft, the eccentric wheel outside is equipped with protective cover, the sieve body connects charging aperture and discharging opening, and sieve body and horizontal plane have top rake.

The utlity model has following beneficial effect: by changing the movement locus of sieve, make the vertical and sieve action of screening machine, so that also doing with sieve, material particles moves both vertically, make material particles produce the vibrations of vertical sieve, qualified material particles is difficult for being blocked in the sieve mesh, strengthened the percent of pass of material particles, simultaneously, by adjusting the eccentric corresponding angle of motor both sides, change the vibration amplitude of sieve, with the material particles that adapts to different specific weight can screening, better pass through sieve, the forward leaning angle of screening machine itself so that material in import screening, travel forward, qualified material particles passive movement is finished screening work to outlet, and it is large that this a kind of screening machine has the screening amount, be difficult for stopping up, can adapt to the characteristics of the screening of different material.

Description of drawings:

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is A-A views of accompanying drawing 1.

Among the figure 1, eccentric wheel; 2, motor shaft; 3, tight fixed bolt; 4, vibration motor; 5, protective cover; 6, the sieve body; 7, charging aperture; 8, main Compress Spring; 9, discharging opening; 10, hinge axis; 11, support spring; 12, top rake.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1 in conjunction with shown in Figure 2, this screening machine comprises sieve body 6 etc., sieve body 6 is supported by four support springs 11, support spring 11 is connected on the hinge axis 10 on the sieve body 6, play the effect of supporting sieve body 6, simultaneously the compression of support spring 11 also so that sieve body 6 can in certain scope, move up and down, while is owing to the reason of top rake 12, sieve body 6 also can be done certain seesawing, be fixed with main Compress Spring 8 on the sieve body 6, above the main Compress Spring 8 vibration motor 4 is arranged, there is motor shaft 2 vibration motor 4 both sides, on each motor shaft 2 eccentric wheel 1 is installed, eccentric wheel is fixed on the motor shaft by tight fixed bolt 3, the outside of eccentric wheel 1 is equipped with protective cover 5, eccentric wheel 1 is so that vibration motor 4 produces vibrations, thereby drive main Compress Spring 8 and produce compression, drive sieve body 6 and do moving both vertically with respect to itself, so that be that material particles is also done moving both vertically with respect to sieve on sieve, underproof particle is forced to vibrations below sieve, qualified particle is under the effect of top rake 14, move to discharging opening 9 from charging aperture 7, finish screening work, material particles for different specific weight, the shockproofness that requires is also different, at this moment needing to adjust the eccentric weight of two eccentric wheels 1 right is the shockproofness of capable of regulating vibration motor 4, when the registration of two eccentric wheels 1 is zero degree, the shockproofness of vibration motor 4 is maximum, the registration of two eccentric wheels 1 is 180 when spending, the shockproofness of vibration motor 4 is minimum, thereby change the shockproofness of sieve body 6, to adapt to different material particles.

Claims

1. screening machine, comprise sieve body (6), it is characterized in that: the hinge axis (10) of sieve body (6) is connected with support spring (11), sieve body (6) is connected with main Compress Spring (8), main Compress Spring (8) connects vibration motor (4), on the axle of vibration motor (4) both sides eccentric wheel (1) is installed, tight fixed bolt (3) connecting eccentric wheel (1) and motor shaft (2), eccentric wheel (1) outside is equipped with protective cover (5), sieve body (6) connects charging aperture (7) and discharging opening (9), and sieve body (1) has top rake (12) with horizontal plane.
