Material-removing type screen tensioning beam

Abstract

The invention relates to a material-removing type screen tensioning beam. The tensioning beam comprises a pair of baffles, the top edges of the two baffles are each connected with a hook plate facing towards the inner side, a gap is reserved between the two hook plates, and the gap can allow hooks at the ends of screens to enter and to be hooked with the hook plates. A partition plate door capable of being opened and closed is arranged between the bottom edges of the two baffles, one end of the partition plate door is hinged to one baffle through a hinged shaft, and the other end of the partition plate door is mounted on the other baffle through a plug. Due to the arrangement of the partition plate door capable of being opened and closed, materials can be stopped from leaking to the lower portion from the connecting positions of a tensioning beam body and the screens when the partition plate door is closed; when working is completed, the partition plate door can be opened, and thus the materials accumulated on the upper surface of the partition plate door can be cleaned up conveniently. Moreover, the hook plates are arranged on the upper portions of the hooks of the screens, and hence hooking is reliable.

Description

technical field [0001] The invention belongs to the technical field of road surface engineering machinery, and relates to a component of asphalt mixing equipment, in particular to a material-clearing screen tensioning beam. Background technique [0002] The asphalt mixing equipment is equipped with a vibrating screen, whose function is to screen the material into several required specifications, and make them enter the corresponding hot bins respectively. The sieve body of the vibrating sieve is provided with a sieve, and the sieve has several layers, and each layer can be divided into two sections, front and back, and is tensioned on the tension beam between the two sections at the same time. [0003] Tension beams in the prior art can generally be classified into C-type, S-type and the like. C-type tension beam such as figure 1 Shown: The C-shaped tension beam is composed of two opposite channel steels and a partition plate welded in the middle, and there will be accumul...

AI Technical Summary

Problems solved by technology

The disadvantage is that after the work is over, people need to enter the inside of the screen body to remove the accumulated material on the partition

The disadvantage is that the hook plate is at the lower part, and the hooking between the screen and the hook plate under the tension beam is unreliable
