Description

Technical Field

[0001] This utility model relates to the field of chute technology, specifically to overflow chute. Background Technology

[0002] A sluice box is a trough typically used on the ground to transport goods from a higher to a lower elevation. It has a smooth inner surface, allowing goods to slide down automatically. It is mainly used in small open-pit mines. In large and medium-sized open-pit mines, sluice boxes are often used in conjunction with ore passes. They can be located within or outside the mining area.

[0003] In existing chutes, the material discharged from the bottom directly impacts the conveyor belt below, causing significant material splashing and further impacting the conveyor belt, which can easily damage it over time. To address these technical problems, we have designed an overflow chute. Utility Model Content

[0004] The purpose of this invention is to provide an overflow chute that has the advantage of buffering falling materials. This solves the problem that when a chute is conveying materials, the material discharged from the bottom directly impacts the conveyor belt below, causing a large amount of material to splash out and further impacting the conveyor belt below, which can easily damage the conveyor belt over time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overflow chute, comprising a belt conveyor, a chute, and a conveyor belt. The inner wall of the chute is connected to several material hoppers. A chute bottom plate is connected to the bottom of the inner wall of the chute. An overflow hood is connected to the bottom of the front side of the chute. An mounting plate is connected to the top of the front side of the chute. An air cannon is mounted on the front side of the mounting plate. An air inlet pipe is connected to the right side of the air cannon. An observation port is mounted on the top of the overflow hood. A dust suction pipe is installed on the top of the front side of the overflow hood. Environmentally friendly sealing covers and baffle plates are installed on the bottom of both the left and right sides of the chute.

[0006] Preferably, the belt conveyor is located above the chute, the conveyor belt is located at the bottom of the chute, and a set of buffer rollers is provided at the bottom of the conveyor belt.

[0007] Preferably, the rear side of the suction pipe extends into the interior of the overflow hood, and a flange is connected to the front side of the outer side of the suction pipe. The suction pipe is L-shaped.

[0008] Preferably, the air cannon's outlet extends into the interior of the chute, and a pressure gauge is installed on the air cannon.

[0009] Preferably, the bottom of the environmentally friendly sealing cover is fitted over the outside of the conveyor belt, the bottom of the baffle plate is in contact with the conveyor belt, the baffle plate is located below the environmentally friendly sealing cover, and both the environmentally friendly sealing cover and the baffle plate are connected to the chute by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model utilizes the combined use of an environmentally friendly sealing cover, a baffle plate, a chute bottom plate, and an overflow cover to buffer falling materials. When materials fall onto the chute bottom plate, due to the angle of the bottom plate, the materials flow through the overflow cover onto the downstream conveyor belt. The material is buffered by the chute bottom plate and no longer directly impacts the downstream conveyor belt, thus reducing material splashing and significantly reducing wear on the downstream conveyor belt. The environmentally friendly sealing cover and baffle plate ensure that materials and dust do not overflow. Attached Figure Description

[0015] Please see Figures 1-2 The overflow chute includes a belt conveyor 1, a chute 2, and a conveyor belt 7. Several material bags 3 are connected to the inner wall of the chute 2. A chute bottom plate 8 is connected to the bottom of the inner wall of the chute 2. An overflow hood 9 is connected to the bottom of the front side of the chute 2. An installation plate 13 is connected to the top of the front side of the chute 2. An air cannon 14 is installed on the front side of the installation plate 13. An air inlet pipe 12 is connected to the right side of the air cannon 14. An observation port 10 is installed on the top of the overflow hood 9. A dust suction pipe 11 is installed on the top of the front side of the overflow hood 9. Environmental protection sealing covers 4 and baffle plates 5 are installed on the bottom of both the left and right sides of the chute 2. The chute bottom plate 8 is set at a certain inclined angle.

[0016] The belt conveyor 1 is located above the chute 2, and the conveyor belt 7 is located at the bottom of the chute 2. The bottom of the conveyor belt 7 is equipped with a set of buffer rollers 6. The belt conveyor 1 facilitates the transport of external materials into the chute 2; the conveyor belt 7 and the set of buffer rollers 6 are part of the belt conveyor.

[0017] The rear side of the suction pipe 11 extends into the interior of the overflow hood 9, and a flange is connected to the front side of the outside of the suction pipe 11. The suction pipe 11 is L-shaped. The side of the suction pipe 11 away from the overflow hood 9 is connected to the external dust removal equipment.

[0018] The air outlet of the air cannon 14 extends into the interior of the chute 2, and a pressure gauge is installed on the air cannon 14; the air cannon 14 can clean up materials adhering to the interior of the chute 2.

[0019] The bottom of the environmentally friendly sealing cover 4 is fitted over the outside of the conveyor belt 7. The bottom of the baffle plate 5 is in contact with the conveyor belt 7. The baffle plate 5 is located below the environmentally friendly sealing cover 4. Both the environmentally friendly sealing cover 4 and the baffle plate 5 are connected to the chute 2 by bolts. Through the cooperation of the environmentally friendly sealing cover 4 and the baffle plate 5, the material falling in the chute 2 can be prevented from splashing out of the conveyor belt 7.

[0020] In operation, materials are transported to the chute 2 via the upstream belt conveyor 1. The material catcher 3 inside the chute 2 provides a material-beating effect during the descent, preventing wear inside the chute 2. The material then falls onto the chute bottom plate 8. Due to the angle of the bottom plate 8, the material flows through the overflow hood 9 onto the downstream conveyor belt 7. The bottom plate 8 cushions the material, preventing direct impact on the downstream conveyor belt 7, thus reducing material splashing and significantly minimizing wear. The observation port 10 allows for continuous monitoring of the material. The environmentally friendly sealing cover 4 and baffle plate 5 prevent material and dust from overflowing. The buffer roller group 6 further cushions the impact of the material on the downstream conveyor belt 7, ensuring a smooth and gradual distribution of material. During material transport in the chute 2, external dust collection equipment is activated to absorb and treat the generated dust, preventing overflow. If blockage occurs inside the chute 2, the air cannon 14 can be activated to clean the interior.

[0021] In summary, this overflow chute, through the combined use of the environmentally friendly sealing cover 4, the baffle plate 5, the chute bottom plate 8, and the overflow cover 9, solves the problem that when the chute is conveying materials, the material discharged from the bottom directly impacts the conveyor belt below, causing a large amount of material to splash out and further impacting the conveyor belt below, which can easily damage the conveyor belt over time.
