Description

Technical Field

[0001] The invention relates to the field of material transportation, in particular to a feeding device for a cone crusher. Background Art

[0002] Cone crushers are usually fed through chutes, which have the disadvantage of uneven feeding. Some materials fall into the receiving tray of the cone crusher, and some materials fall on the moving cone of the cone crusher, which will have a greater impact on the moving cone of the cone crusher, causing the cone crusher to be easily overloaded, often damaging the copper sleeve and wearing the cone body lining.

[0003] A mobile feeding hopper for a belt conveyor (document number "CN204433736U") discloses a feeding scheme, i.e., the material is first weighed by a metering belt feeder and then fed; although the feeding device in the document can accurately control the feeding amount, the material is still in a scattered state after being discharged from the discharge end of the metering belt feeder. If it is directly applied to the feeding of a cone crusher, it cannot be guaranteed that the material will accurately fall into the receiving tray of the cone crusher. Summary of the invention

[0004] The object of the present invention is to provide a feeding device for a cone crusher, so as to feed materials to a receiving plate of the cone crusher in a centralized manner and reduce the impact on the moving cone of the cone crusher.

[0005] The present invention can be implemented through the following technical scheme: a cone crusher feeding device, a belt conveyor is fixed on a movable frame, a vertically arranged guide hopper is provided at the downstream end of the belt conveyor, the guide hopper is a conical hopper with a larger aperture at the top and a smaller aperture at the bottom, and the downstream end of the belt conveyor is arranged in a cantilevered state relative to the frame.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After the materials fall from the downstream end of the belt conveyor, they can all be collected by the guide hopper and discharged from the discharge port at the bottom of the guide hopper, so that the materials are concentrated and fed to the receiving tray of the cone crusher. The center point of the cone of the cone crusher makes the falling materials evenly distributed, while reducing the impact on the moving cone of the cone crusher. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] See also Figure 1-2As shown, a feeding device for a cone crusher is provided, wherein a belt conveyor 10 is fixed on a movable frame 20, and a vertically arranged guide hopper 30 is provided at the downstream end of the belt conveyor 10. The guide hopper 30 is a conical hopper with a larger aperture at the top and a smaller aperture at the bottom. The downstream end of the belt conveyor 10 is arranged in a cantilevered state relative to the frame 20. When feeding the cone crusher, the feeding device is located beside the cone crusher, and the bucket core of the guide hopper 30 coincides with the center of the feed port of the cone crusher. The downstream end of the belt conveyor 10 falls down. The materials are gathered by the guide hopper 30 and then discharged from the discharge port at the bottom of the guide hopper 30, so that the materials are concentrated and fed to the receiving plate of the cone crusher, and the falling materials are evenly distributed through the center point of the cone of the cone crusher, while reducing the impact on the moving cone of the cone crusher; wherein the downstream end of the belt conveyor 10 is arranged in a cantilevered state relative to the frame 20, so that the guide hopper 30 is conveniently arranged below the downstream end of the belt conveyor 10, so that the guide hopper 30 can be located directly above the feed port of the cone crusher 10.

[0011] The bucket core of the guide hopper 30 is located at the symmetrical center of the belt width direction of the belt conveyor 10. The guide hopper 30 is a quadrangular pyramid and a pair of bucket walls on opposite sides are located on one side of the belt width direction of the belt conveyor 10, and another pair of bucket walls on opposite sides are located on one side of the belt length direction of the belt conveyor 10. Such an arrangement allows the material to be collected by the guide hopper 30 and discharged from the discharge port at the bottom of the guide hopper 30 after falling from the downstream end of the belt conveyor 10, so that the material is concentratedly fed to the receiving plate of the cone crusher, thereby reducing the impact on the moving cone of the cone crusher.

[0012] A protective cover 40 is also installed on the frame 20, and the belt conveyor 10 is located inside the protective cover 40; the setting of the protective cover 40 prevents the dust generated by the materials transported on the belt conveyor 10 from being emitted into the external environment; a corresponding exhaust device can be provided on the protective cover 40, and the dust can be sucked by the exhaust device for collection and treatment.

[0013] The top edge of the guide hopper 30 is connected to the bottom opening of the shield 40 and is located at the falling path of the material; the shield 40 and the guide hopper 30 are of an integrated design, and the shield 40 provides support for the installation of the guide hopper 30.

[0014] A feed hopper 41 for receiving materials to the belt conveyor 10 is provided at the top of the upstream end of the guard 40 ; the feed hopper 41 receives the materials 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 to a scraper for scraping sticky materials on the belt surface of the belt conveyor 10; the scraper is not shown in the figure, and the scraper motor 50 drives the scraper to move to scrape sticky materials on the belt surface of the belt conveyor 10, thereby facilitating the cleaning of the belt surface of the belt conveyor 10.

[0016] Traveling wheels 21 are provided at the bottom of the frame 20. When the traveling wheels 21 are displaced along the track, the guide hopper 30 is respectively located above the feed port of the cone crusher or beside the feed port of the cone crusher. There are four traveling wheels 21, which are symmetrically arranged in pairs at the bottom of the frame 20. The four traveling wheels 21 support the frame 20. The frame 20 can move on the ground by the rolling of the traveling wheels 21 on the ground track, so that the guide hopper 30 is respectively located above the feed port of the cone crusher or beside the feed port of the cone crusher.

[0017] The distance L between the projection position of the front wheel 21A of the traveling wheel 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; by setting the horizontal distance L between the front wheel 21A of the traveling wheel and the downstream end of the belt conveyor 10, the downstream end of the belt conveyor 10 is arranged in a cantilevered state relative to the frame 20, which facilitates the arrangement of the guide hopper 30 below the downstream end of the belt conveyor 10; at the same time, the setting of the distance L ensures that the feeding device will not tip over toward the downstream end of the conveyor 10.

[0018] The rear wheel 21B of the traveling wheel is arranged directly below the upstream end of the belt conveyor 10, and a motor 22 for driving the traveling wheel 21 to move is arranged on the frame 20 at the position of the rear wheel 21B of the traveling wheel; since the downstream end of the belt conveyor 10 is arranged in a cantilevered state relative to the frame 20, the mass center of the belt conveyor 10 does not coincide with the mass center of the frame 20. When the weights of the materials transported 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 wheel 21B of the traveling wheel, and the weight of the motor 22 is used to balance the entire feeding device to suppress the feeding device from tipping over toward the downstream end of the conveyor 10. At the same time, the setting of the distance L further ensures that the tendency of the conveyor 10 to tip over is eliminated. In the above, the two rear running wheels 21B are connected through a wheel axle, and the motor 22 converts electrical energy into mechanical energy, generates a rotational torque through the output shaft, and this torque is transmitted to the wheel axle through a transmission system (such as a reducer, etc.). The torque acts on the wheel axle, thereby driving the rear running wheels 21B to rotate, so that the frame 20 moves forward or backward.

[0019] The feed hopper 41 is arranged near the upstream end of the belt conveyor 10; on the one hand, the feed hopper 41 is used to realize the feeding of the belt conveyor 10, and on the other hand, the tendency of the feeding device to tip over to the downstream end of the conveyor 10 is suppressed by increasing the weight of the upstream end of the belt conveyor 10.
