Abstract
The utility model relates to a spring-adjusting device for a vibrating screen. The spring-adjusting device comprises a spring, a guide holder, an adjustable lever and a reset spring which are fixed at the bottom of the vibrating screen. A fixing hole is axially reserved at the top center of the guide holder. One end of the reset spring is fixed at the bottom surface of the fixing hole, and the other end is fixed at the bottom of the adjustable lever. The bottom of the spring is fixed on the top surface of the guide holder. The adjustable lever is located inside the spring, and the top surface of the adjustable lever is lower than that of the spring. By the arrangement, up and down vibration of a screen body can be guaranteed, and meanwhile, horizontal swaying of the screen body can be effectively prevented. Besides, the spring-adjusting device for the vibrating screen is simple in structure and convenient to mount and demount.
Description
Technical field
The utility model relates to a kind of vibratory sieve, especially a kind of spring regulating device that is installed in the vibratory sieve bottom.
Background technology
In the prior art, the sieve nest of most of vibratory sieves is mounted on the spring of four vertical placements, and sieve nest is realized vibrating effect under vibrating motor drives and produce continuous up-down vibration.But, during use, these are placed on the sieve nest on the spring, often understand up-down vibration incessantly, swing that also can the occurred level direction not only influences the normal use of vibratory sieve, but also will damage on the vibratory sieve damage as other parts such as springs, both be unfavorable for using, in the service life of also having reduced vibratory sieve, increased maintenance cost.
For this reason, the people in the industry is by making great efforts in many ways, designed a kind of sieve nest that props up in the horizontal direction, to prevent the device of sieve nest horizontal hunting, but this device in use, not only influenced the up-down vibration of sieve nest to a certain extent, and the structure more complicated of this device, dismounting and maintenance are all very inconvenient, and manufacturing cost is also than higher.
The utility model content
The utility model purpose is to provide a kind of to prevent the sieve nest horizontal hunting in order to overcome the deficiencies in the prior art, and simple in structure, the vibratory sieve spring regulating device of easy accessibility.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vibratory sieve spring regulating device comprises the spring, guide holder, adjusting rod and the back-moving spring that are fixed on the vibratory sieve bottom; Axially have a fixing hole in the described guide holder top in the heart; One end of described back-moving spring is fixed on the bottom surface of fixing hole, and the bottom of the other end and adjusting rod is fixed; The bottom of described spring is fixed on the guide holder end face; Described adjusting rod is positioned at spring, and its end face is lower than the spring end face.
Preferably, the cross section of described fixing hole is T shape, and the spring bottom is fixed on the upper end of fixing hole.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
A kind of vibratory sieve spring regulating device of the utility model scheme, adopt back-moving spring control and regulation bar, spring to the sieve nest bottom leads, when guaranteeing the sieve nest up-down vibration, also effectively prevented the horizontal hunting of sieve nest, and the vibratory sieve spring regulating device of the utility model scheme is simple in structure, easy accessibility.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the perspective view of vibratory sieve spring regulating device of the present utility model;
Accompanying drawing 2 is the cutaway view of vibratory sieve spring regulating device of the present utility model;
Wherein: 1, spring; 2, guide holder; 3, fixing hole; 4, back-moving spring; 5, adjusting rod.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1,2 is a kind of vibratory sieve spring regulating device described in the utility model, comprises the spring 1, guide holder 2, adjusting rod 5 and the back-moving spring 4 that are fixed on the vibratory sieve bottom; Described guide holder axially has a fixing hole 3 in 2 tops in the heart; One end of described back-moving spring 4 is fixed on the bottom surface of fixing hole 3, and the bottom of the other end and adjusting rod 5 is fixed; The cross section of described fixing hole 3 is T shape, and spring 1 bottom is fixed on the upper end of fixing hole 3; The bottom of described spring 1 is fixed on guide holder 2 end faces; Described adjusting rod 5 is positioned at spring 1, and its end face is lower than spring 1 end face.
During use, owing to adopt back-moving spring 4 control and regulation bars 5, the spring 1 bottom the sieve nest is led, when the sieve nest up-down vibration, adjusting rod 5 is corresponding up-down vibration also, when guaranteeing the sieve nest up-down vibration, has also effectively prevented the horizontal hunting of sieve nest like this.The vibratory sieve spring regulating device of the utility model scheme is simple in structure, and dismounting and maintenance are also very convenient.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
