Problems solved by technology

During operation, the vibrating screen swings back and forth in a circular arc under the control of the boom. Since the overall weight of the vibrating screen is entirely borne by the hanging hinge point of the boom, it not only increases the wear on the boom, but also vibrates greatly, reducing the tool life

Embodiment Construction

[0010] The following describes the creative implementation of the present invention in detail with reference to the accompanying drawings. A thresher vibrating screen load-bearing vibration reduction mechanism includes a vibrating screen 1 and a frame 6. A vibration damping frame 2 is fixedly mounted on the side of the vibrating screen 1, and the vibration damping frame 2 is fixedly mounted vertically parallel to each other Two threaded guide rods 8, on the lower side of the two threaded guide rods 8, are fitted with a roller seat 3 that can be moved up and down, and a damping spring 7 and a pressure are respectively installed on the two threaded guide rods 8 Adjusting nut 9, the upper and lower end surfaces of the damping spring 7 are in contact with the pressure adjusting nut 9 and the roller seat 3 respectively. The upper end of the damping spring 7 is axially locked on the threaded guide rod 8 by the pressure adjusting nut 9, and the roller 4 is fitted on a roller seat 3, a...

Abstract

The invention provides a thresher vibrating screen bearing and shock absorbing mechanism, and belongs to the field of agricultural machines. A shock absorbing frame is fixedly installed on the side of a vibrating screen, two threaded guided rods are fixedly and vertically installed on the shock absorbing frame in a mutually parallel mode, a rolling wheel base is installed on the lower sides of the two threaded guide rods in a matched and vertically movable mode, shock absorbing springs and pressure adjusting nuts are installed on the threaded guide rods, the upper end faces and the lower end faces of the shock absorbing springs make contact with the corresponding pressure adjusting nuts and the rolling wheel base in a matched mode respectively, the upper ends of the shock absorbing springs are axially locked on the corresponding threaded guide rods through the corresponding pressure adjusting nuts, a rolling wheel is assembled on the rolling wheel base, a supporting rail is fixedly installed on the rack, and the rolling wheel makes contact with the supporting rail in a matched mode. The thresher vibrating screen bearing and shock absorbing mechanism is novel and reasonable in structure, steady in machine tool operating and running, little in machine tool abrasion and long in service life.

Description

Technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a load-bearing vibration reduction mechanism of a vibrating screen on a threshing machine. Background technique [0002] On the threshing machines currently in use, the vibrating screens are all hinged and mounted on the machine with a single boom hanging structure. During operation, the vibrating screen swings back and forth in a circular arc under the control of the boom. As the overall weight of the vibrating screen is borne by the hanging hinge point of the boom, it not only increases the wear on the boom, but also the vibration of the machine is large, which reduces The service life of the machine tool. Summary of the invention [0003] The purpose of the invention is to design a thresher vibrating screen load-bearing damping mechanism in view of the above-mentioned problems in the prior art, so as to reduce the wear of the vibrating screen hanging structure, reduce machine vibratio...
