A griddle anti-collision protective device is provided with obliquely installed screen cloth; a vibration motor serves as a vibration source of the screen cloth; the screen cloth is installed on integrated screen cloth brackets through elastic screen cloth force bearing devices; a feeding inlet is formed above the screen cloth; an inclined anti-collision plate is arranged below the feeding inlet; springs are arranged under the anti-collision plate; an anti-abrasion rubber layer is arranged on the anti-collision plate; and the anti-collision plate is connected with the vibration motor. The griddle anti-collision protective device has the beneficial effects that the anti-collision plate is arranged below the feeding inlet, when falling down, stones fall on the anti-collision plate instead of directly colliding the screen cloth, and the screen cloth can be effectively protected; in addition, the vibration motor drives the anti-collision plate to vibrate, and thus the stones can uniformly fall on the screen cloth; and furthermore, the springs arranged under the anti-collision plate has a buffering effect, and accordingly noise can be reduced. The griddle anti-collision protective device is simple in structure and easy to maintain.
Description
technical field [0001] The invention relates to an ore grading and screening device, in particular to an ore screen anti-collision protection device used in the ore washing production process. Background technique [0002] In the production process after the preliminary washing of raw calcite ore, the classification and screening of ore is an essential process link. In September 2012, it applied for an invention patent with the patent number 2012204858427 and the name "a vibrating screening device for ore washing machine". However, when the ore is screened with this device, when the ore falls from the discharge port of the hopper to the screen, the ore will hit the screen, which will deform or even damage the screen after a long time, affecting normal production. In the actual production process, the screen mesh is often deformed and damaged. Contents of the invention [0003] The object of the present invention is to provide a mine screen anti-collision protection devic...
