Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a feed port structure of a bucket elevator. Background Art

[0002] During the loading process of a bucket elevator, materials directly impact the elevator's internal structure, generating a significant impact force. For example, when lifting materials such as dry powder and granules, the materials fall from the loading port at a certain speed and weight. Direct impact may cause deformation or damage to internal elevator components such as the hopper and transmission components. For example, the ring chain in a chain bucket elevator is prone to wear and breakage if subjected to significant impact forces over a long period of time, affecting the normal operation of the elevator and shortening the equipment's service life. This situation is more pronounced when lifting large amounts of material or when the material is heavy, such as when conveying heavy materials such as coal and rocks, where the risk of damage from impact is even greater.

[0003] The Chinese patent document with publication number CN213678251U discloses a feeding buffer device for an elevator, which relates to the field of buffer devices and includes a buffer box, a feed port is formed at the top of the buffer box, a first fixed plate is provided inside the buffer box, a first spring is installed at the top of the first fixed plate, a first buffer plate is connected to the top of the first spring, a rubber layer is provided on the surface of the first buffer plate, and a fixed block is connected to the inner wall of the buffer box. By providing the first buffer plate, the first spring, the second buffer plate, the second spring and the rubber layer, the feed is transported from the feed port to the inside of the buffer box, the feed falls from the feed port and squeezes the first buffer plate, the first buffer plate squeezes the first spring, and the first spring compresses to reduce the shock of the feed entering the feed port, thereby playing a buffering role. The impact force of the falling feed on the first buffer plate is reduced by providing the rubber layer, thereby further buffering the feed.

[0004] In the aforementioned patent solution, although the addition of a buffer plate and spring reduces the impact of falling materials, the buffer plate does not completely cover the entire feed port, meaning some material may still pass over the buffer plate and directly impact the bottom or side walls of the feed port. Furthermore, the increased coverage of the buffer plate also reduces the horizontal cross-sectional area of ​​the feed port, reducing the elevator's lifting efficiency to a certain extent. This can also cause jamming or blockage when handling large, long, or strip-shaped items. Utility Model Content

[0005] In order to overcome the problems in the prior art where the buffer plate provided at the feed inlet of the elevator has a too large coverage area, which reduces the lifting efficiency of the material, and a too small coverage area, which causes the material to pass over the buffer plate and directly impact the inner wall of the feed inlet, one object of the utility model is to provide a feed inlet structure for a bucket elevator, wherein two movable plates connected to springs are respectively arranged at different heights and different side walls of the feed inlet, the two movable plates are staggered and completely cover the feed inlet, thereby buffering the impact of the material on the feed inlet without dead angles, while also ensuring a sufficiently large material passage area.

[0008] Furthermore, an inclined surface is provided inside the secondary feed port below the two buffer parts; the upper end of the inclined surface is located at the lower end of the lowest fixed plate, and the lower end of the inclined surface is located at the bottom end of the secondary feed port.

[0009] The material entering through the vertical opening is buffered by the two movable plates and guided by the inclined surface, which gradually reduces the impact force and ensures a sufficiently large material flow rate.

[0010] Furthermore, the secondary feed port is a cylindrical structure with an L-shaped structure; the lower end of the secondary feed port is a horizontal opening facing the elevator, and the upper end is a vertical opening facing upward; one of the movable plates is located above the horizontal opening, and the other movable plate is located inside the horizontal opening.

[0011] After excess material enters the secondary feed port, the excess material can also enter the horizontal opening from the side of the lowest movable plate to avoid accumulation and blockage.

[0012] Furthermore, two rows of symmetrically arranged convex strips are respectively provided on the inclined surface and the inner wall of the secondary feed port away from the horizontal opening; each row of convex strips includes a plurality of metal rods uniformly arranged linearly along the longitudinal direction; the metal rods are arranged at an angle, and one end close to the side wall of the secondary feed port is lower than the other end.

[0013] The metal rod increases the wear resistance of the inner wall of the secondary feed port.

[0014] Specifically, a central slope is provided on the upper end of the movable plate; the central slope is inclined toward the middle of the secondary feed port.

[0015] Furthermore, it includes a slide plate, which is tilted and arranged in the first-level feed port; a fluctuating plate, the upper end of which is rotatably connected to the middle of the slide plate, and the vibration motor is arranged at the lower end of the fluctuating plate; and a baffle, which has two baffles, which are respectively arranged on both sides of the slide plate; wherein the baffle is located above the fluctuating plate, and the distance between the baffle and the slide plate can be adjusted.

[0016] The vibration motor drives the fluctuating plate to vibrate, thereby preventing the material from adhering and accumulating at the primary feed port.

[0017] Optionally, the baffle is slidably connected to the side wall of the primary feed port; and a positioning bolt for locking the position of the baffle is provided on the baffle.

[0018] Optionally, the baffle is detachably connected to the side wall of the primary feed port; a plurality of linearly arranged mounting holes are provided on the side wall of the primary feed port; and the baffle is fixed by positioning bolts passing through the corresponding mounting holes.

[0019] The vibration amplitude of the baffle can be adjusted by the limiting effect of the baffle, and is suitable for conveying a variety of different materials.

[0023] 1. The two movable plates used for buffering completely cover the bottom of the secondary feed port on the horizontal plane, reducing the impact of transported materials on the bottom of the secondary feed port without dead angles. At the same time, the distance between a single movable plate and the side wall of the secondary feed port is large, ensuring that the material has a large enough passing area, which reduces the impact and wear on the bottom of the secondary feed port while ensuring the material flow efficiency.

[0024] 2. The first-level feed port is connected to the fluctuating plate by rotating on the inclined sliding plate. The fluctuating plate vibrates under the drive of the vibration motor, which further reduces the impact of the vertical fall of the material and prevents the accumulation of the material on the inclined plate.

[0025] 3. Through the setting of the primary feed port and the secondary feed port, the overall structure is simple, without a large number of tiny parts, with high integration, and is suitable for use in harsh (dust, moisture, etc.) and high-intensity working conditions.
