Cushion damping device for slamming screen

Abstract

The invention discloses a cushion damping device for slamming screen. The cushion damping device comprises a base, a rectangular outer casing and an striking rod. A top of the damping spring fixed onthe upper surface of the base is fixed with a metal frame, and the first screen and the second screen are disposed inside the metal frame The circular wheel fixed on the surface of the rectangular outer casing is connected with the rotary electric machine inside the rectangular outer casing, the top of the rotating shaft mounted on the surface of the rectangular outer casing is provided with a swinging rod, and the small gear opened at the rear end of the swinging rod and the large gear opened on the upper surface of the striking rod are engaged with each other The right of the horizontal rodfixed to the right side surface of the metal frame is provided with a groove, the groove is fixed to the convex block fixed on the left surface of the rectangular casing, and the left end surface of the striking rod is provided with a metal damping soundproof felt. The cushion damping device for slamming screen solves the problem that no shock absorption measure and noise is too much by providinga damping spring, a circular wheel, a rotating electric machine, a swinging rod, a rotating shaft, a small gear, a large gear, a horizontal rod, a groove, a convex block and a metal damping soundprooffelt.

Description

technical field [0001] The invention relates to the technical field of slapping sieves, in particular to a buffer and shock absorbing device for slapping sieves. Background technique [0002] The slapping sieve, also known as the slapping vibrating sieve, is one of the commonly used testing instruments in the laboratory. It is a special equipment for testing the particle size of the test sieve. The structure is mainly composed of machine base, sieve and transmission mechanism. Inspection, superhard material production classification and material composition inspection. It is widely used in scientific research and production laboratories of geology, metallurgy, chemical industry, medicine, national defense and other departments to screen and test materials. [0003] But prior art exists described following deficiency: [0004] 1. The traditional slap screen lacks shock absorption measures and has a short service life; [0005] 2. When the slapping screen is working, the no...
