Vibratory sieve is that the reciprocating rotary type utilizing oscillator exciting to produce vibrates and works.The industry such as extensive coal, metallurgy, water power, mine, building materials, chemical industry, electric power, traffic, harbour
Present vibratory sieve is primarily of screen box, vibrator, suspension (or supporting) composition such as device and motor.Motor, through V belt, drives vibrator main shaft gyration, due to the centrifugal intertia force effect of weight uneven on vibrator, makes screen box obtain vibration.Change vibrator eccentric weight, can various amplitude be obtained.
But the price comparison of vibrator is expensive, concerning some small business, buy pressure comparatively greatly, the vibratory sieve that the applicant replaces this vibrator to encourage desirable to provide a kind of simple structure.
Summary of the invention
The invention provides a kind of double-deck screen shale shaker of strap cam, to solve the problem replacing the vibratory sieve encouraged with vibrator by simple structure.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of double-deck screen shale shaker of strap cam, comprise base, first screen cloth, second screen cloth and support spring, first screen cloth and the second screen cloth are fixed on base by support spring, also comprise cam, push rod, pole and the drive rod be positioned on the second screen cloth, described cam is rotatably connected on base, one end of pole is hinged on cam, the other end of pole is hinged on the first screen cloth, cam can offset with drive rod, one end of push rod is connected on the end face of cam, the other end is provided with the cam segment that can offset with the second screen cloth.
Principle of the present invention is: cam rotates, drive pole swing, because pole is connected on the first screen cloth, first screen cloth can vibrate under the drive of pole, when the maximum wire diameter place of cam and drive rod offset, drive rod can along the radial vibration of cam, and because being connected to the second screen cloth place during drive rod, therefore the second screen cloth also can along the radial vibration of cam.Because the end face of cam is provided with push rod, push rod is provided with the cam segment that can offset with the second screen cloth, and the direction that push rod overhead cam section is arranged is vertical with the radial direction of cam, therefore push rod can drive the second screen cloth along the axial vibration of cam.
Compared with prior art, the invention has the advantages that: drive Double-layer screen motion by cam structure and rod-like structure, the vibration of the second screen cloth along both direction (radial and axial along cam) can be realized, alternative vibrator, and structure is simple, draw materials common, cost is lower, is applicable to small business.
Further, described support spring comprises support bar, connecting rod, first spring and the second spring, support bar is provided with bearing pin, one end of connecting rod is slidably connected on bearing pin, the other end is hinged on the second screen cloth, and the first spring is vertically arranged between connecting rod and support bar, and the second spring horizontal is arranged between connecting rod and support bar.As adopted leaf spring etc. as support spring simply, support force can be made not enough, therefore be provided with support bar, support bar and the second screen cloth adopt connecting rod to be connected, and ensure that the intensity of connection.
Further, described cam is provided with at least two installing holes, and pole is hinged on cam by installing hole, can select different installing holes as required, thus regulates the Oscillation Amplitude of the first screen cloth.
Further, drive rod is slidably connected on the second screen cloth, regulates the second screen cloth along the amplitude of cam radial vibration by regulating the position of drive rod.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation of the double-deck screen shale shaker embodiment of strap cam of the present invention.
Fig. 2 is the structural representation of the double-deck screen shale shaker support spring embodiment of strap cam of the present invention.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, first screen cloth 2, second screen cloth 3, support bar 4, connecting rod 5, cam 6, push rod 7, pole 8, drive rod 9.
As shown in Figure 1, the double-deck screen shale shaker of a kind of strap cam 6 in the present embodiment, comprises base 1, first screen cloth 2, second screen cloth 3 and support spring, and the first screen cloth 2 and the second screen cloth 3 are fixed on base 1 by support spring.As shown in Figure 2, support spring comprises support bar 4, connecting rod 5, first spring and the second spring, support bar 4 is provided with bearing pin, one end of connecting rod 5 is slidably connected on bearing pin, the other end is hinged on the second screen cloth 3, and the first spring is vertically arranged between connecting rod 5 and support bar 4, and the second spring horizontal is arranged between connecting rod 5 and support bar 4.The drive rod 9 that this structure also comprises cam 6, push rod 7, pole 8 and is slidably connected on the second screen cloth 3.Described cam 6 is rotatably connected on base 1, and cam 6 is provided with three installing holes, and the lower end of pole 8 is hinged on cam 6 by installing hole, and the upper end thereof of pole 8 is on the first screen cloth 2, and cam 6 can offset with drive rod 9.The lower end of push rod 7 is connected on the end face of cam 6, and upper end is provided with the cam segment that can offset with the second screen cloth 3.
When this structure is in running order, be connected by motor with cam 6, cam 6 can rotate in the radial direction thereof, drives pole 8 to swing, and because pole 8 is connected on the first screen cloth 2, the first screen cloth 2 can vibrate under the drive of pole 8.When the maximum wire diameter place of cam 6 and drive rod 9 offset, drive rod 9 can side-to-side vibrations, and because being connected to the second screen cloth 3 place during drive rod 9, therefore the second screen cloth 3 also can side-to-side vibrations.End face because of cam 6 is provided with push rod 7, and push rod 7 is provided with the cam segment that can offset with the second screen cloth 3, and the direction that push rod 7 overhead cam section is arranged is vertical with the radial direction of cam 6, therefore push rod 7 can drive the second screen cloth 3 porpoise.
