Description

Technical Field

[0001] This utility model relates to the field of lifting conveyor technology, specifically to a feeding device for a lifting telescopic conveyor. Background Technology

[0002] A lifting conveyor is an automated conveying equipment that integrates vertical lifting and horizontal movement functions. Its core structure includes a support frame, a lifting device, and a transmission system. According to patented technology, the equipment generally adopts a scissor lift mechanism and a ball screw drive assembly to achieve height adjustment, and a guide rail limit device to ensure operational stability. Depending on the conveying method, it can be divided into hydraulically driven belt conveyor equipment and spiral tower vertical conveyor.

[0003] The existing feeding device of the telescopic lifting conveyor is a fixed structure and is not linked with the lifting movement of the main unit. This causes the feed inlet to fail to maintain effective alignment with the upstream equipment during equipment adjustment, resulting in a series of operational problems such as material spillage and increased impact. At the same time, because the feeding device lacks the ability to follow up and adjust, it cannot respond to the lifting action of the main unit, which may cause material to impact the edge of the belt, resulting in abnormal wear of components, shortening their service life, and disrupting the continuity and stability of material transmission. Therefore, the feeding device of the existing telescopic lifting conveyor needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a lifting telescopic conveyor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a lifting telescopic conveyor, comprising a frame, a conveying assembly installed on one side of the frame, and an angle adjustment assembly provided on the top of the frame. A feeding device assembly is installed at the other end of the angle adjustment assembly. The angle adjustment assembly includes a first ear plate, which is fixedly connected to one side of the frame. A bushing is slidably connected to the inner wall of the first ear plate, and a second ear plate is slidably connected to the outer wall of the bushing. A pin is penetratingly connected to the inner wall of the bushing, and slots are provided at both ends of the pin. A retaining spring is installed on the outer wall of the slots. A support assembly is installed on the other side of the feeding device assembly.

[0006] Preferably, there are two bushings, each bushing passing through two sets of first and second lug plates respectively, and the bushings are made of copper.

[0007] Preferably, the first ear plate is raised and lowered by the frame, and the second ear plate is adjusted at an angle with the first ear plate by a bushing.

[0008] Preferably, the feeding device assembly includes a feeding bin, and the top of the feeding bin has a feeding port, and the inner wall of the feeding port is provided with a guide plate.

[0009] Preferably, there are two guide plates, and the two guide plates are symmetrically arranged with the vertical line of the inlet as the axis of symmetry, and an outlet is provided between the two guide plates.

[0010] Preferably, the support assembly includes spring seats, and two spring seats are respectively fixedly connected to the frame and the feeding device assembly.

[0011] Preferably, a spherical washer is movably connected to the outer wall of the spring seat, and an adjustment port is provided through the center of the spherical washer. The diameter of the adjustment port is larger than the diameter of the spring seat, and a compression spring is provided between the two adjustment ports.

[0012] Compared with the prior art, the beneficial effects of this utility model are: it is used for feeding devices of lifting telescopic conveyors;

[0013] 1. By setting the angle adjustment component, the angle of the feeding device component is driven to rise and fall synchronously with the conveyor, always maintaining spatial alignment with the discharge port of the upstream equipment. Since the feeding port is always aligned, the material enters smoothly along the guide path, greatly reducing material leakage, spillage, and dust, improving material utilization, and improving the on-site environment. At the same time, the material drop is constant, avoiding "falling from a height" or "lateral impact" caused by misalignment, effectively protecting the frame and key components inside the conveying component, and extending the service life of the equipment.

[0014] 2. Through the set support components, after the adjustment port is pre-compressed, it is always under pressure and continuously pushes upward against the guide chute, effectively supporting its own weight and avoiding the front end sagging due to gravity when unloaded or lightly loaded. This ensures that the material slides smoothly, thereby providing continuous support force, maintaining the stability of the posture, and preventing the guide chute from sagging. At the same time, when large pieces of material fall into the guide chute, they generate instantaneous impact. The spring absorbs part of the kinetic energy, reducing vibration and noise and extending the service life of the equipment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a feeding device for a lifting telescopic conveyor, including a frame 1, a conveying assembly 2 installed on one side of the frame 1, and an angle adjustment assembly 3 installed on the top of the frame 1. A feeding device assembly 4 is installed at the other end of the angle adjustment assembly 3. The feeding device assembly 4 includes a feeding bin 401, and a feeding port 402 is opened on the top of the feeding bin 401. A guide plate 403 is provided on the inner wall of the feeding port 402. The feeding port 403 enhances the feeding efficiency. The structural strength of 402 is enhanced, improving impact resistance, while optimizing material flow trajectory and reducing dust and spillage. There are two guide plates 403, symmetrically arranged about the vertical axis of the inlet 402. An outlet 404 is provided between the two guide plates 403. The symmetrical arrangement of the two guide plates 403 forms a "V-shaped" flow guide structure, which helps to concentrate material flow and avoid uneven loading. The angle adjustment component 3 includes a first ear plate 301. 01 is fixedly connected to one side of the frame 1. A bushing 302 is slidably connected to the inner wall of the first ear plate 301. There are two bushings 302, each penetrating both sets of first ear plates 301 and second ear plates 303. The bushings 302 are made of copper. Through the bushings 302, excellent self-lubricating and wear-resistant properties are achieved, significantly reducing the frictional resistance between the first ear plate 301 and the second ear plate 303. The outer wall of the bushing 302 is slidably connected to the second ear plate 303. The frame 1 forms a lifting motion, and the second ear plate 303 forms an angle adjustment motion with the first ear plate 301 through the bushing 302. The second ear plate 303 slides relative to the pin 304 through the bushing 302, forming a free swing of the feed hopper around the hinge point. It can automatically adapt to the height change of the host and realize the spatial centering of the feed port. The inner wall of the bushing 302 is connected to the pin 304, and the two ends of the pin 304 are provided with slots 305. The outer wall of the slots 305 is equipped with snap rings 306.

[0022] On the other side of the feeding device assembly 4, a support assembly 5 is installed. The support assembly 5 includes a spring seat 501. Two spring seats 501 are fixedly connected to the frame 1 and the feeding device assembly 4 respectively. Through the spring seats 501, the compression spring 504 can extend and retract synchronously with the swing of the feeding bin 4. While providing continuous upward support force, it allows free angle adjustment. A spherical pad 502 is movably connected to the outer wall of the spring seat 501. An adjustment port 503 is opened through the center of the spherical pad 502. The diameter of the adjustment port 503 is larger than the diameter of the spring seat 501. A compression spring 504 is arranged between the two adjustment ports 503. Through the spherical pad 502, the end face of the compression spring 504 is allowed to tilt within a small range to compensate for the axial deflection caused by the swing of the feeding bin 401, prevent the spring from being subjected to lateral bending moment, and protect its fatigue life.

[0023] Example 1: First, a pin 304 passes through two sets of first ear plates 301 and second ear plates 303, and is equipped with a bushing 302 to reduce friction. Since the pin 304 has a slot 305 at both ends, a retaining spring 306 is installed in the slot 305 to prevent it from falling off. When the lifting mechanism drives the frame 1 and the conveying assembly 2 to lift as a whole, the feeding device assembly 4 swings freely around the axis through the hinge structure formed by the first ear plate 301 and the second ear plate 303 at the tail and the pin 304, so that the feeding bin 401 can be lifted and adjusted synchronously with the host machine. This allows the material to be guided by the guide plate 403 and fall stably through the discharge port 404 onto the conveying assembly 2. At the same time, the feeding bin 401 always maintains spatial alignment with the discharge port of the upstream equipment to ensure that the material flows in smoothly and avoids spillage and impact.

[0024] Example 2: In the support assembly 5 set in the middle of the frame 1, the compression spring 504 and the spherical pad 502 are on the spring seat 501. The upper and lower ends are respectively connected to the frame and the feed hopper through the two spring seats 501. During installation, the compression spring 504 is pre-compressed by a certain amount so that it is always under pressure and continuously provides upward elastic support force, effectively supporting the weight of the feeding device assembly 4, preventing the front end from sagging when unloaded, and absorbing kinetic energy when large pieces of material are impacted, buffering vibration, and protecting welds, hinges and conveying components. Since the diameter of the adjustment port 503 is larger than the diameter of the spring seat 501, the spherical pads 502 installed at both ends of the compression spring 504 can compensate for the small angular deviation during the swing process, ensuring uniform force. Through mechanical linkage, automatic centering, stable material guiding, elastic support and vibration damping are achieved, ensuring the continuity and stability of the conveying process and the service life of the equipment.
