Technical Field
[0001] This utility model relates to the field of material conveying equipment technology, specifically to a belt conveyor hopper device. Background Technology
[0002] A belt conveyor hopper device generally includes a belt conveyor hopper and a conveyor belt located below the hopper. The belt conveyor hopper collects and discharges powdery materials from a height onto the conveyor belt, which then transports them to a silo or other transport equipment.
[0003] The belt conveyor hopper device is a key piece of equipment in bulk material conveying systems, primarily used for buffering, diverting, and efficiently conveying materials. Its structural design effectively reduces the impact force when materials fall, prevents material accumulation or splashing, and improves conveying efficiency. It is suitable for industries such as mining, building materials, chemicals, and food processing.
[0004] However, existing belt conveyor hopper devices may cause a large amount of dust when the material enters the conveyor belt from the hopper. At the same time, the falling powder may cause the material to scatter onto the ground, resulting in poor conveying efficiency and poor production efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a belt conveyor hopper device to solve the above-mentioned problems.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A belt conveyor hopper device includes a belt conveyor hopper and a belt conveyor disposed below the belt conveyor hopper;
[0008] The belt conveyor hopper includes a hopper body, which includes a feed inlet with a square horizontal cross-section at the top and a discharge outlet with a rectangular horizontal cross-section at the bottom. The hopper body includes a funnel-shaped feed section and a cuboid-shaped discharge section. The connection between the feed section and the discharge section is smoothly transitioned. The feed inlet is located at the top of the feed section, and the discharge outlet is located at the bottom of the discharge section.
[0009] The belt conveyor includes a conveyor belt and a dust-blocking device arranged around the periphery of the conveyor belt to prevent powder from scattering. The dust-blocking device includes a gantry frame arranged in front of and behind the discharge section and side frames connected to both sides of the front and rear gantry frames. The frame structure formed by the front and rear gantry frames and the side frames surrounds the discharge section. The gantry frame is provided with a connecting plate and presses the front dust-blocking belt and the rear dust-blocking belt together through the connecting plate. The two side frames include side plates that converge toward the conveyor belt from top to bottom, and a left dust-blocking belt and a right dust-blocking belt arranged on the side plates.
[0010] Furthermore, the dust-blocking device also includes several fixing plates disposed on the outer side of the side plate. The fixing plates have elongated grooves extending outward. The outer side of the left and right dust-blocking strips is provided with a composite pressure plate for pressing the left and right dust-blocking strips against the side plate. The composite pressure plate includes a connecting plate and a pressure plate disposed under the connecting plate. The connecting plate has elongated grooves to be fitted onto the fixing plate through the elongated grooves. The outer side of the composite pressure plate is provided with a pressing plate. The pressing plate has elongated grooves to be fitted onto the fixing plate through the elongated grooves. The long grooves of the fixing plate are embedded with wedges to act on the pressing plate so that the pressing plate presses the left and right dust-blocking strips tightly through the composite pressure plate.
[0011] Furthermore, the pressure plate is an angle iron structure, the connecting plate is a plate-shaped structure, and the clamping plate is an L-shaped structure. When clamping, the vertical part of the clamping plate is pressed onto the angle iron of the pressure plate, and the horizontal part of the clamping plate is pressed onto the side plate.
[0012] Furthermore, the wedge is fixed to the side plate by a chain link at the top of the wedge.
[0013] Furthermore, the left dust barrier, right dust barrier, front dust barrier, and rear dust barrier are rubber strips; the front dust barrier and rear dust barrier are cut into several strips.
[0014] Furthermore, the length-to-width ratio of the bottom of the discharge port is 8-11:25-35, and the length of the discharge port is less than or equal to the side length of the inlet.
[0015] Furthermore, the hopper body is fixedly connected to a fixed frame, the fixed frame including a fixed frame and several columns, the hopper body is fixedly connected to the fixed frame, and the columns are fixedly connected to the bottom of the fixed frame.
[0016] Furthermore, a belt conveyor is provided at the bottom of the hopper body, the belt conveyor is directly opposite the discharge port of the hopper body, and the width of the belt conveyor is greater than the width of the discharge port.
[0017] Compared with the prior art, the advantages and positive effects of this invention are:
[0018] The anti-clogging conveyor hopper of this utility model features a square inlet and a rectangular outlet. This design results in different inclinations of the four steel plates that make up the funnel-shaped hopper body. Specifically, the inclinations of two adjacent steel plates are different. This design causes the material falling into the hopper body to fall at different speeds on different inclined plates, thereby avoiding interference and clogging of materials at the same height.
[0019] This invention improves conveying efficiency and production efficiency by installing a dust-blocking device around the discharge section to prevent powder from falling beyond the conveyor belt and causing material to scatter off the belt. The front and rear dust-blocking belts prevent material scattering and reduce dust, while the left and right dust-blocking belts on both sides gather the falling powder, preventing it from falling off.
[0020] This utility model also optimizes the structure and size of the discharge port to ensure that the material does not get stuck in the distribution hopper and can be evenly distributed on the belt to improve conveying efficiency.
[0021] This utility model has a stable overall structure, strong adaptability, and is suitable for high-load working conditions. Attached Figure Description

[0032] In this embodiment, a belt conveyor 4 is provided at the bottom of the hopper body 1. The belt conveyor 4 is directly opposite the discharge port 121 of the hopper body 1, and the width of the belt conveyor 4 is greater than the width of the discharge port 121 to prevent material from spilling.
[0033] In this embodiment, the belt conveyor 4 includes a conveyor belt and a dust-blocking device arranged around the periphery of the conveyor belt to prevent powder from scattering. The dust-blocking device includes a gantry frame 3 arranged in front of and behind the discharge section and side frames connected to both sides of the front and rear gantry frames 3. The frame structure formed by the front and rear gantry frames 3 and the side frames surrounds the discharge section. The gantry frame 3 is provided with a connecting plate 6 and presses the front dust-blocking belt 7 and the rear dust-blocking belt (the front dust-blocking belt 7 and the rear dust-blocking belt are symmetrical front to back and have the same specifications and dimensions) through the connecting plate 6.
