Description

Technical Field

[0001] The present invention belongs to the technical field of ore processing, and particularly relates to an ore crushing device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties, and can be divided into metallic minerals and non-metallic minerals. The mined ore needs to be crushed to ensure the transportation and deep processing efficiency of the ore.

[0003] Chinese Patent No. CN117463445B discloses an ore crushing device. By driving the corresponding crushing rollers to rotate towards each other, the ore falls between the oppositely arranged crushing rollers and is first crushed by the extrusion of multiple crushing rollers. The large pieces of crushed stone will roll down along the inclined screening plate to between the first extrusion plate and the second extrusion plate. During the reciprocating swing of the screening plate, the second extrusion plate can also be driven to move up and down, so as to extrude and crush the large pieces of crushed stone, that is, secondary crushing. The above device has the following disadvantages: Since the first extrusion plate is connected to the support block through a spring, when the second extrusion plate extrudes the crushed stone, the first extrusion plate will be forced to move to the side away from the second extrusion plate, which not only reduces the force on the crushed stone, but also affects the crushing effect of the crushed stone.

For example, the angle formed between the first bearing plate 3 and the second bearing plate 301 is 120°, and the angle formed between the first extrusion plate 4 and the second extrusion plate 401 is 105°. It is set that the range of the angle formed between the first bearing plate 3 and the first extrusion plate 4 is 7° - 20°, and it is required that the upper edge of the first bearing plate 3 cannot rotate between the first bearing plate 3 and the rotating shaft 5; when the angle formed between the first bearing plate 3 and the first extrusion plate 4 is the largest, the distance between the lower edge of the second extrusion plate 401 and the second bearing plate 301 is less than the distance between the upper edge of the second extrusion plate 401 and the second bearing plate 301, and when the angle formed between the first bearing plate 3 and the first extrusion plate 4 is the smallest, the distance between the lower edge of the second extrusion plate 401 and the second bearing plate 301 is slightly greater than the distance between the upper edge of the second extrusion plate 401 and the second bearing plate 301; when the angle formed between the first bearing plate 3 and the first extrusion plate 4 gradually becomes smaller, the ore in the first crushing chamber 6 is in the extrusion crushing stage, and the ore in the second crushing chamber 7 is discharged, and when the angle formed between the first bearing plate 3 and the first extrusion plate 4 gradually becomes larger, the ore in the second crushing chamber 7 is in the extrusion crushing stage; a driving mechanism 8 is connected to the second extrusion plate 401; the driving mechanism 8 can drive the second extrusion plate 401 and the first extrusion plate 4 to rotate synchronously; the driving mechanism 8 is installed on the support plate 2.During use, the ore is put into the first crushing chamber 6 formed between the first pressing plate 4, the first bearing plate 3 and the two support plates 2.
