Embodiment Construction

[0014] In order to further understand the structure, features and other purposes of the present invention, it is now described in detail in conjunction with the attached preferred embodiments as follows:

[0015] The specific implementation of the embodiment of the present invention is as follows:

[0016] Such as figure 1 versus figure 2 Shown: a four-wheel drive non-constant 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. The front eccentric wheel 8 and the rear eccentric wheel 3 are rotatably connected with the frame 4, and the front eccentric wheel 8 The eccentricity of is greater than the eccentricity of the rear eccentric 3 and the...

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-constant-amplitude vibrating screen mechanism used on a non-constant-amplitude material cleaning screen suitable for agricultural materials and mining materials. Background technique [0002] After harvesting agricultural materials, it is necessary to separate the stalks, residual stalks and leaves, immature fruits, soil blocks, and broken soil from mature fruits. The vibrating screen mechanism in the existing cleaning screen usually only works under one amplitude condition, and the motion track of each part of the vibrating screen is the same, and the amplitude and vibration intensity of each part are also the same. Since the material on the screen surface of the vibrating screen is relatively concentrated at the input end of the vibrating screen, the material layer is relatively thick at the back of the screen when the material has just reached the screen surfac...
