[0010] Please refer to Figs. 1-2As shown, a cone crusher feeding device, a belt conveyor 10 is fixed on a movable frame 20, and a vertical material guide hopper 30 is arranged at the downstream end of the belt conveyor 10, the material guide hopper 30 is a conical hopper with a large aperture at the top and a small aperture at the bottom, and the downstream end of the belt conveyor 10 is arranged in a cantilevered manner relative to the frame 20; when feeding the cone crusher, the feeding device is located beside the cone crusher, and the core of the material guide hopper 30 coincides with the center of the feed inlet of the cone crusher, the material falling from the downstream end of the belt conveyor 10 is collected by the material guide hopper 30, and then discharged from the discharge port at the bottom of the material guide hopper 30, so that the material is concentrated and fed to the receiving disc of the cone crusher, and the falling material is uniformly distributed through the center point of the cone of the cone crusher, while reducing the impact on the movable cone of the cone crusher; wherein the downstream end of the belt conveyor 10 is arranged in a cantilevered manner relative to the frame 20, which facilitates the arrangement of the material guide hopper 30 below the downstream end of the belt conveyor 10, so that the material guide hopper 30 can be located directly above the feed inlet of the cone crusher 10.

[0011] The core of the material guide hopper 30 is located on the center of symmetry of the belt width direction of the belt conveyor 10, the material guide hopper 30 is a quadrangular pyramid, and a pair of opposite side walls are located on one side of the belt width direction of the belt conveyor 10, and the other pair of opposite side walls are located on one side of the belt length direction of the belt conveyor 10; such arrangement enables the material falling from the downstream end of the belt conveyor 10 to be completely collected by the material guide hopper 30 and discharged from the discharge port at the bottom of the material guide hopper 30, so that the material is concentrated and fed to the receiving disc of the cone crusher, thereby reducing the impact on the movable cone of the cone crusher.

[0012] A shroud 40 is also mounted on the frame 20, and the belt conveyor 10 is located inside the shroud 40; the shroud 40 is arranged to prevent dust generated by the material conveyed on the belt conveyor 10 from being dispersed into the external environment; a corresponding air suction device can be provided on the shroud 40 to achieve suction of the dust for collection and treatment.

[0013] The top edge of the material guide hopper 30 is connected in sequence at the opening at the bottom side of the shroud 40, and is located at the falling path of the material; the shroud 40 and the material guide hopper 30 are designed in an integrated manner, and the shroud 40 provides support for the installation of the material guide hopper 30.

[0014] The upstream end of the shroud 40 is provided with a feed hopper 41 for receiving material to the belt conveyor 10; the feed hopper 41 receives the material to be crushed onto the belt surface of the belt conveyor 10.

[0015] A scraper motor 50 is arranged below the material output side of the belt conveyor 10, and the output shaft of the scraper motor 50 is connected with a scraper for scraping the material on the belt surface of the belt conveyor 10; wherein the scraper is not shown in the figure, the scraper motor 50 drives the scraper to move, scrapes the material on the belt surface of the belt conveyor 10, and facilitates the cleaning of the belt surface of the belt conveyor 10.

[0016] The bottom of the frame 20 is provided with walking wheels 21, which are displaced along the track and make the material guide hopper 30 be above or aside the feeding port of the cone crusher; the walking wheels 21 are provided in pairs and symmetrically arranged at the bottom of the frame 20, and the four walking wheels 21 support the frame 20; the frame 20 can be moved on the ground through the rolling of the walking wheels 21 on the ground track, so that the material guide hopper 30 is above or aside the feeding port of the cone crusher.

[0017] The distance L between the projection position of the front walking wheel 21A on the belt conveyor 10 and the downstream end of the belt conveyor 10 accounts for two-fifths of the overall length of the belt conveyor 10; the horizontal distance L between the front walking wheel 21A and the downstream end of the belt conveyor 10 is arranged so that the downstream end of the belt conveyor 10 is arranged in a cantilevered manner relative to the frame 20, which facilitates the arrangement of the material guide hopper 30 below the downstream end of the belt conveyor 10; meanwhile, the distance L ensures that the feeding device will not tip over to the downstream end of the conveyor 10.

[0018] The rear walking wheels 21B are arranged directly below the upstream end of the belt conveyor 10, and the frame 20 at the position of the rear walking wheels 21B is provided with a motor 22 for driving the walking wheels 21; since the downstream end of the belt conveyor 10 is arranged in a cantilevered manner relative to the frame 20, the mass center of the belt conveyor 10 does not coincide with the mass center of the frame 20, and when the weights of the materials conveyed by the upstream and downstream ends of the belt conveyor 10 are not equal, the entire feeding device may tip over; in order to avoid this situation, the motor 22 is installed on the frame 20 at the position of the rear walking wheels 21B, and the weight of the motor 22 is used to balance the entire feeding device and prevent the feeding device from tipping over to the downstream end of the conveyor 10; meanwhile, the distance L further ensures that the tendency of the conveyor 10 to tip over is eliminated. In the above, the two rear walking wheels 21B are connected by an axle, the motor 22 converts electrical energy into mechanical energy and generates a rotating torque through an output shaft, the torque is transmitted to the axle through a transmission system (such as a reducer), and the torque acts on the axle to drive the rear walking wheels 21B to rotate, so that the frame 20 moves forward or backward.

[0019] The feeding hopper 41 is arranged near the upstream end of the belt conveyor 10; the feeding hopper 41 is used to load the belt conveyor 10 and increase the weight of the upstream end of the belt conveyor 10 to prevent the feeding device from tipping over to the downstream end of the conveyor 10.
