Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0028] Such as figure 1 As shown, a two-degree-of-freedom parallel mechanism vibrating screen according to the present invention includes a moving platform 1, a static platform 2, three parallel branches connecting the moving platform 1 and the static platform 2, and a control system. Such as figure 2 As shown, the three parallel branches are 2-RRRR⊥SR asymmetric parallel mechanism, including A branch R A1 / / R A2 ⊥ R A3 / / R A4 , B branched chain R B1 ∥ R B2 ⊥ R B3 ∥ R B4 and redundant branches S E1 R E2 , the three branches are perpendicular to each other in space. In the A branch chain, one end of the A branch chain crank 3 passes through the rotating pair R A1 It is connected with the static platform 2, and the two ends of the A branch chain connecting rod ...

Abstract

The invention provides a two-degree of freedom parallel mechanism vibrating screen. The two-degree of freedom parallel mechanism vibrating screen comprises a movable platform, a static platform and three parallel branches connecting the movable platform and the static platform. The parallel branches are 2-RRRR-SR asymmetrical parallel mechanisms, comprising an A branch, a B branch and a redundant branch. The A branch and the B branch are driven through a motor M1 and a motor M2 correspondingly. The static platform and the movable platform are parallel to each other in a motionless status. A vibrating screen is arranged on the movable platform. The vibrating screen is provided with two-layer screen surfaces. The static platform is provided with a plurality of objects receiving boxes. According to the two-degree of freedom parallel mechanism vibrating screen, the two-degree of freedom parallel mechanism is controlled to move through an ROBO controller, the multi-dimensional vibration can be realized. An eccentric wheel is adopted to replace a crank in the main load direction and the adaptability is enhanced. The two-degree of freedom parallel mechanism vibrating screen can quickly separate paper money and coins, and clean and distribute one yuan coins, half yuan coins and dimes. The two-degree of freedom parallel mechanism vibrating screen is simple in structure, easy to manufacture and process, capable of being widely used in the multi-dimensional vibration occasions in engineering, and also capable of being applied to the classification or screening of objects.

Description

technical field [0001] The invention relates to vibrating screening equipment, in particular to a two-degree-of-freedom parallel mechanism vibrating screen. Background technique [0002] Parallel mechanism has incomparable advantages over series mechanism, and it is more and more used in robots and crop harvesting machines. At present, vibrating screens at home and abroad include various types, such as resonant screens, linear vibrating screens, and swirl probability screens. Chinese patent number ZL200920143613.5 discloses a four-degree-of-freedom hybrid vibrating screen, which can only screen crop seeds. However, other objects cannot be screened for coins. Many units in China are studying coin sorting, and have achieved good results in terms of coin sorting, but there is still a lack of devices that can accurately sort paper and coins. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a two-degree-of-freedom parallel...
