[0001] The invention relates to the field of crushing equipment, in particular to an integrated crushing and screening device for mining. Background Art

[0002] Ore mining is the process of extracting mineral resources from the crust of the earth or other celestial bodies. Ore mining is a comprehensive, long-term and high-risk engineering activity that requires comprehensive consideration and management in terms of technology, environment and socio-economics to ensure sustainable development of resources and protect the long-term health of the environment. Ore raw materials usually need to be crushed after ore mining, which is used for preliminary crushing and processing of the original ore excavated from the ore deposit to make it suitable for further processing and refining.

[0013] Working principle: First, the staff will introduce the mined ore raw materials into the first shell from the feed port, and the raw materials will enter between the two crushing rollers. The first motor will start. While driving the roller on one side to rotate, the first motor will drive the two spur gears to engage and transmit, thereby driving the two rollers to rotate inward at the same time, thereby driving the two crushing rollers to rotate inward at the same time, and use the rotating crushing roller to perform preliminary crushing of the ore raw materials. The ore raw materials after preliminary crushing will fall between the two movable jaw plates, and the roller will also drive the driving gear to rotate while rotating. Through the meshing transmission of the driving gear and the driven gear, the transmission shafts on both sides are driven to rotate, thereby driving the worm in the middle to rotate, and the rotating worm will engage and transmit with the worm wheel, thereby driving the short shaft and the cylinder body to rotate. Since there is a certain angle between the oblique bearing seat and the central axis of the cylinder body, when the cylinder body rotates, it will drive the oblique bearing seat to swing left and right, thereby driving the push-pull rod to follow the movement, and the left and right movable push-pull rods will drive the top of the inner movable jaw plate to move back and forth, thereby realizing the two The movable jaw plates are opened and closed continuously to further crush the ore raw materials falling between the movable jaw plates to improve the crushing effect. The crushed ore raw materials will fall onto the screen. At this time, the second motor is started, and the second motor drives the rotating rod to rotate, driving the cam to rotate. The rotating cam will drive one end of the connecting rod to move back and forth, thereby driving the screen to vibrate back and forth to achieve the screening effect of the raw materials. At the same time, since the screen is inclined, the incompletely crushed raw materials will fall onto the return plate, and the rotating rod will also drive the driving wheel to rotate during rotation. Through the transmission of the transmission belt, the driven wheel and the lower movable shaft will be driven to rotate. The transmission gear and gear belt on the movable shaft are used to drive the gear belt to move counterclockwise, thereby driving the return plate inside the gear belt to transport upward, and the incompletely crushed raw materials are transported to the opening. Then, the blocking effect of the resistance plate inside the opening is used to tilt the return plate, and the uncrushed raw materials are poured onto the inclined plate, so that the raw materials are returned to the first shell through the feed port along the inclined plate for secondary crushing, thereby improving the crushing effect.

[0014] The present invention provides an integrated crushing and screening device for mining. It has the following beneficial effects:

[0015] 1. The present invention achieves the initial crushing effect on the raw materials by driving the two crushing rollers to move inward at the same time through the rotating roller, and at the same time uses the movable jaw plate that continuously opens and closes under the crushing roller to perform secondary crushing on the raw materials, thereby improving the crushing effect of the ore raw materials.

[0016] 2. The present invention utilizes a rotating rotating rod and a cam to realize the back-and-forth vibration of the screen, thereby achieving a screening effect after crushing. At the same time, the side moving return plate is utilized to transport the incompletely crushed ore raw materials back to the feed port, thereby achieving re-crushing of the raw materials, thereby further improving the screening effect and crushing quality of the ore raw materials.
