Description

Technical Field

[0001] This invention relates to a bucket elevator for vertical conveying, and more specifically to an anti-wear mechanism at the discharge port of a bucket elevator. Background Technology

[0002] Bucket elevators are vertical lifting equipment used for transporting bulk and fragmented materials. They are widely used in industries such as chemical materials, metallurgy, food, and cement. Their structural forms include... Figure 1 As shown, after being lifted by hopper A, the material falls through a tipping bucket at the head of the elevator to the discharge port B. During this falling process, some material spills onto the casing C at the discharge port, causing continuous wear and impact on the machine body at that location, significantly affecting the machine's service life and stability during operation. Existing technology has employed welding wear-resistant plates onto the casing at the discharge port to improve its service life; however, this method is problematic because replacing damaged wear-resistant plates is extremely inconvenient, making equipment maintenance difficult. Furthermore, the welded wear-resistant plates cannot completely offset the impact of the material on the machine body; the continuous impact negatively affects the machine's stability and service life. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a material settling anti-wear mechanism at the discharge port of a bucket elevator, which uses material settling to achieve anti-wear and reduce the impact force of the material on the machine body, thereby extending the service life.

[0004] To achieve its objectives, the present invention employs the following technical solution:

[0005] The feature of the anti-wear mechanism for the sedimentation material at the discharge port of the elevator of the present invention is that the anti-wear mechanism is fixedly installed on the shell of the elevator discharge port on the side impacted by the material using a sedimentation back plate. A sedimentation grid plate is provided on the sedimentation back plate. The sedimentation grid plate is formed by parallel and spaced sedimentation plates. Each sedimentation plate has its inner side facing the inside of the bin as its inner side and its outer side connected to the sedimentation back plate as its outer side. The inner side of the sedimentation plate is set higher than the outer side, so that the material can be deposited on each sedimentation plate to form anti-wear protection for the sedimentation back plate and the elevator shell.

[0006] The anti-wear mechanism for the sinking material at the discharge port of the elevator of the present invention is characterized by: two vertical limiting plates are set, the bottom and top of the limiting plates are connected to the sinking material back plate through connecting parts, and side slots are set on the side of the limiting plates, and the inner side of each sinking material plate is embedded in the side slots to obtain vertical positioning.

[0007] The anti-wear mechanism for the sinking material at the discharge port of the elevator of this invention is characterized by being an adjustable structure, comprising: an inner side slot on the inner side of the sinking plate, wherein the side slot of the limiting plate is engaged with the inner side slot of the sinking plate, thereby hinged to the sinking plate; an outer side slot on the outer side of the sinking plate, wherein a hook is provided on the sinking back plate, wherein the hook is engaged with the outer side slot of the sinking plate, thereby hinged to the sinking plate; the limiting plate is fixedly connected to the sinking back plate at its bottom end by a connecting plate and bottom bolts; the limiting plate is limited at its top end by a top bolt in the slide groove of the guide rail plate, wherein the guide rail plate is fixedly mounted on the sinking back plate; and the set bearing angle of the sinking plate is obtained by adjusting the position of the top end of the limiting plate in the slide groove.

[0008] The characteristic of the anti-wear mechanism for the sinking material at the discharge port of the elevator of the present invention is that the sinking plate is a flat plate or an arc plate.

[0010] Compared with existing technologies, the beneficial effects of this invention are reflected in:

[0011] 1. This invention utilizes a material sink plate to receive materials, allowing the materials to accumulate on the sink plate. The deposited materials block the wear and impact on the machine casing, effectively achieving wear resistance and reducing the impact force of the materials on the machine body, thereby extending the service life and improving the stability of equipment operation.

[0012] 2. The speed of the material during the operation of the elevator has different requirements for the receiving angle of the sinking plate. The present invention sets the sinking anti-wear mechanism as an adjustable structure, so that users can adjust the receiving angle of the sinking plate according to the actual operation, and obtain the set material layer height in a targeted manner to ensure effective sinking anti-wear in actual operation.

[0013] 3. Different types of sink plates in this invention can be used interchangeably, allowing for targeted selection when dealing with powder and lumpy materials, thus ensuring the anti-wear effect of the sink plate.

[0022] Figure 1 The diagram shows the structure of a bucket elevator. After the material is lifted from bucket A, it falls to the outlet B through a tipping bucket at the head of the elevator. During this falling process, some material is thrown onto the shell C at the outlet of the elevator, causing wear and impact on the machine body at the corresponding position. This affects the service life and working stability of the machine body. In this embodiment, a material sinking anti-wear mechanism is set at the outlet of the elevator to extend the service life of the machine body and improve the working stability.

[0023] Figure 2 and Figure 3 As shown, in this embodiment, the sinking anti-wear mechanism 1 is fixedly installed on the housing 2 on the side of the elevator discharge port that is impacted by the material using a sinking back plate 4. The guide plate 3 at the discharge port is located on the opposite side of the sinking anti-wear mechanism 1. A sinking grid is provided on the sinking back plate 4. The sinking grid is formed by parallel and spaced sinking plates 5. Each sinking plate 5 has its inner side facing the bin as its inner side and its outer side connected to the sinking back plate as its outer side. The inner side of the sinking plate 5 is set higher than the outer side, so that the material can be deposited on each sinking plate 5 to form anti-wear protection for the sinking back plate and the elevator housing.

[0024] In practice, the corresponding structural measures also include:

[0025] like Figure 3 As shown, two vertical limiting plates 6 are set. The bottom and top of the limiting plates 6 are connected to the back plate of the sink material through connectors. The side of the limiting plates 6 is provided with a slot. The inner side of each sink material plate 5 is embedded in the slot to obtain vertical positioning and improve the structural stability.

[0026] To meet specific user needs, the anti-wear mechanism for the sinking material is designed to be adjustable, and includes:

[0027] See Figure 3Figures 4a, 4b, 5, and 6 illustrate that, as reinforcement, round rods 13 are respectively provided on both sides of the sinker plate 5. An inner side latch 5a is provided on the inner side of the sinker plate 5, and the side groove 6a of the limiting plate 6 is engaged with the inner side latch 5a of the sinker plate 5, thus achieving a hinged connection between the sinker plate 5 and the limiting plate 6. An outer side latch 5b is provided on the outer side of the sinker plate 5, and a hook 9 is provided on the sinker back plate, which is engaged with the outer side latch 5b of the sinker plate 5, thus achieving a hinged connection between the sinker plate 5 and the sinker back plate. The limiting plate 6... The bottom end is fixedly connected to the sinking back plate 4 via connecting plate 8 and bottom bolt 10a; the limiting plate 6 is limited in the slide groove 14 of the guide rail plate 7 at the top via top bolt 10b, and the guide rail plate 7 is fixedly set on the sinking back plate; in this way, the sinking plate 5, the limiting plate 6, the guide rail plate 7 and the connecting plate 4 form a parallelogram structure, and the set bearing angle of the sinking plate 5 can be obtained by adjusting the position of the top of the limiting plate 6 in the slide groove 14; the fasteners used to connect the components greatly facilitate adjustment and disassembly, and make maintenance convenient.

[0028] In this embodiment, the sink plate 5 can be configured as a flat plate 11 or an arc plate 12. The flat plate 11 is suitable for conveying powder, while the arc plate 12 is more suitable for conveying granular and blocky materials. Its arc surface effectively reduces the impact of materials on the sink plate and reduces wear.

[0029] This invention can make adaptive adjustments to the shape and receiving angle for different materials, thereby changing the height of the material layer, reducing the impact of the material on the machine body, improving the stability of the bucket elevator, extending its service life, and reducing the difficulty of equipment maintenance.
