Embodiment Construction

[0015] In order to further understand the structure, characteristics and other purposes of the present invention, now in conjunction with the attached preferred embodiments are described in detail as follows:

[0016] Embodiments of the present invention are implemented as follows:

[0017] Such as figure 1 and figure 2 Shown: a four-wheel drive non-equal amplitude vibrating screen mechanism, including a vibrating screen 10 and a vibrating mechanism, the vibrating mechanism includes a pair of front eccentric wheels 8, a pair of rear eccentric wheels 3, a pair of front multi-stage connecting rods and a For the rear multi-stage connecting rod, the front eccentric wheel 8 and the rear eccentric wheel 3 are driven by the transmission mechanism 11, and the front eccentric wheel 8 and the rear eccentric wheel 3 are rotatably connected to the frame 4. The front eccentric wheel 8 The eccentricity is greater than the eccentricity of the rear eccentric wheel 3 and the transmission me...

Abstract

An all-wheel-drive non-amplitude vibrating screen mechanism comprises a vibrating screen and a vibrating system. The vibrating system comprises a pair of front eccentric wheels, a pair of rear eccentric wheels, a pair of front multi-stage connecting rods and a pair of rear multi-stage connecting rods. The front eccentric wheels and the rear eccentric wheels are driven by a transmission mechanism, and are connected with a frame rotatably; the eccentric distance of the front eccentric wheels is large than that of the rear eccentric wheels. The front multi-stage connecting rods are in three-segment connecting rod structure, and the rear multi-stage connecting rods are in two-segment connecting rod structure. According to the all-wheel-drive non-amplitude vibrating screen mechanism, since the front multi-stage connecting rods adopts the three-segment connecting rod structure, the rear multi-stage connecting rods adopts the two-segment connecting rod structure, by means of driving by the eccentric wheels and interactive effect of structures of the vibrating screen and the like, so that the moving track of the front end of the vibrating screen is in a shape of a transverse 8, the moving track of the rear end of the vibrating screen is elliptical, vibrating directions of the entire screen surface are increased, and better screening effect is achieved.

Description

technical field [0001] The invention relates to a vibrating screen mechanism, in particular to a four-wheel drive non-uniform amplitude vibrating screen mechanism used on a non-uniform material cleaning sieve suitable for cleaning agricultural materials and mining materials. Background technique [0002] After harvesting agricultural materials, stems, residual stems and leaves, immature fruits, soil clods, crushed soil, etc. need to be separated from mature fruits, etc. The vibrating sieve mechanism in the existing cleaning sieve usually only works under one amplitude condition, and the movement track of each part of the vibrating screen is the same, and the amplitude and vibration intensity of each part are also the same. Because the material on the screen surface at the feeding end of the vibrating screen is relatively concentrated, the material layer is relatively thick at the rear section of the screen where the material has just reached the screen surface. In order to p...
