Feeding adjusting device for screening machine

Abstract

The invention discloses a feeding adjusting device for a screening machine. The feeding adjusting device comprises a rack, and a feeding port fixing slot, a feeding port adjustable slot and a blanking port formed in the rack. The feeding port fixing slot is hinged to the feeding port adjustable slot, the feeding port adjustable slot is connected to a driving device, the driving device can drive the feeding port adjustable slot to rotate, the feeding port fixing slot and the feeding port adjustable slot are formed in the top of the blanking port, the feeding port fixing slot is formed obliquely toward the direction of the blanking port, the blanking port can be connected to a feed inlet of the screening machine, and a material is conveyed to a screen surface of the screening machine. By arranging the feeding port adjustable slot, a blanking position of the material is adjusted. The feeding port fixing slot is formed obliquely toward the direction of the blanking port, so that the material slides under the action of gravity. The feeding port fixing slot is hinged to the feeding port adjustable slot, and the driving device changes a projection position of the end, far away from the feeding port fixing slot, of the feeding port adjustable slot in the blanking port by driving the feeding port adjustable slot to rotate, so that a purpose of adjusting the material blanking position is achieved.

Description

technical field [0001] The invention relates to the technical field of screening equipment and its peripheral supporting connection devices, in particular to a feed adjustment device for a screening machine. Background technique [0002] Screening machines are widely used in the classification and screening of broken materials. According to the difference in structure and screen surface movement form, screening machines can usually be divided into vibrating screening machines, drum screening machines, relaxation screening machines, bar screening machines, vibrating wind screens, etc. Composite screening machine and other forms. When the screening machine is working, the material enters the screen surface at a certain speed and inclination, and through different forms of movement on the screen surface, the material is gradually dispersed, segregated, and separated through the screen. The incident speed, angle and position of the material will affect the sorting effect and sc...
