[0002] As a material conveying device, belt conveyors can continuously transport materials to processing equipment. In order to feed materials into the belt conveyor, a feeding device is usually installed at the head of the belt conveyor.

[0003] When conveying materials, in order to ensure that the particle size of the materials meets the requirements of the processing equipment, the materials need to be screened. Currently, materials are generally screened by vibrating screens. This process generates a lot of dust, which is inconvenient to collect and affects the processing environment. In addition, the screening method of vibrating screens is difficult to break up clumps of materials. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a belt conveyor feeding device that can screen and disperse materials and prevent dust leakage.

[0005] According to an embodiment of the present invention, a feeding device for a belt conveyor includes a box body disposed above the conveyor belt and having an opening at the bottom. A screen cylinder is rotatably disposed inside the box body, and a spirally arranged pushing blade is fixedly connected inside the screen cylinder. A feeding component and a discharging component are respectively disposed at both ends of the screen cylinder. A rotary drive mechanism that is pulsatorically connected to the screen cylinder is fixedly disposed outside the box body. A receiving cylinder surrounding the screen cylinder is also fixedly connected inside the box body. A discharge port is provided at the bottom of the receiving cylinder. A dust removal mechanism is also provided on the box body.

[0006] Preferably, the feeding assembly includes a feeding cylinder coaxially connected to the screen cylinder and a side cover rotatably connected to the feeding cylinder. The feeding cylinder passes through the housing and is rotatably connected to it. The side cover is disposed outside the housing and connected to the housing through a support rod. A feeding pipe extending into the feeding cylinder is also fixedly connected to the side cover. The feeding cylinder is drively connected to the rotary drive mechanism.

[0007] More preferably, the discharge assembly includes a discharge cylinder coaxially connected to the screen cylinder, a collection cover fixed outside the box and surrounding the outlet of the discharge cylinder, the discharge cylinder passing through the box and rotatably connected thereto, and a discharge hopper connected to the bottom of the collection cover.

[0008] More preferably, the two sides of the box are fixedly provided with brackets, the rotary drive mechanism includes a power component fixed on the brackets and a drive gear that is drivenly connected to the power component, the feed cylinder is provided with a transmission tooth groove, and the drive gear abuts against and meshes with the transmission tooth groove.

[0009] More preferably, the dust removal mechanism includes a first dust removal pipe disposed on the top of the box and communicating with the receiving cylinder, and a second dust removal pipe disposed on the side of the box and facing the discharge port.

[0010] More preferably, a brush roller is rotatably connected inside the receiving cylinder, and the brush roller is disposed at the top of the screening cylinder and in contact with it.

[0011] In a further preferred embodiment, the top of the box is provided with a first observation channel communicating with the receiving cylinder, and the bottom of the box is provided with a second observation channel facing the discharge port. Both the first observation channel and the second observation channel are provided with a cover.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] A screen cylinder with spiral pusher blades is installed to allow large particles of material to fall onto the belt conveyor. The rotation of the screen cylinder enables the material to be screened and conveyed. The centrifugal force also improves the screening efficiency. Furthermore, the rotation, tumbling, and centrifugal force help disperse agglomerated materials, which is beneficial for material screening. Attached Figure Description
