Description

Technical Field

[0001] This utility model relates to the technical field of bucket elevators, and in particular to the technical field of a feed inlet device that can reduce the impact of tail feed. Background Technology

[0002] Bucket elevators are mainly composed of a head casing, a middle casing, a tail section, running parts (chains, buckets), a drive unit, and a tensioning device.

[0003] Bucket elevators typically use a method where wear-resistant materials are added to the inner wall of the inclined feed inlet. However, these materials are often expensive, and they eventually wear through over time. Furthermore, it's difficult to monitor the wear on the feed inlet's inner wall during operation. Failure to replace the material promptly can lead to dust accumulation and conveying malfunctions. Therefore, this method incurs high manufacturing and maintenance costs. To address this, most plate chain elevators now use a right-angle inlet connected to the tail section. The feed inlet has an inclined plate on the side furthest from the tail section, creating a layer of material that abrades the material, preventing it from wearing through the inner wall. However, this type of feed inlet results in a large impact force on the inclined plate when material enters, which can also cause wear and noise. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a feed inlet device that can reduce the impact of the tail feed, thereby achieving buffering and shock absorption during the feeding process, thus improving service life and reducing noise.

[0005] To achieve the above objectives, this utility model proposes a feed inlet device that can mitigate the impact of tail feed, comprising a right-angle feed inlet body, two elastic support mechanisms and a guide plate. The right-angle feed inlet body has slots on both sides of the corner, and each slot has an elastic support mechanism. The elastic support mechanism has a guide plate located inside the right-angle feed inlet body. The guide plate is inclined with the front lower than the rear. The upper surface of the guide plate has a plurality of wear-resistant plates arranged in sequence, and the wear-resistant plates are fixedly connected to the guide plate by a plurality of screws.

[0006] Preferably, the elastic support mechanism includes a connecting plate, a bearing seat, a sliding plate, a screw seat, a screw, a buffer spring, an adjusting nut, and a support. The connecting plate has an oblong hole, and a sliding plate that closes the oblong hole is slidably disposed on the outer side of the connecting plate. The sliding plate has a bearing seat, a screw seat, and a screw. The lower end of the screw passes through the support disposed on the connecting plate. An adjusting nut located below the support is disposed on the screw. A buffer spring is sleeved on the screw between the screw seat and the support.

[0007] Preferably, the connecting plate is provided with two guide rails located on the outer sides of both ends of the slide plate, and the slide plate is provided with two limiting plates located on the corresponding sides of the two guide rails.

[0008] Preferably, both ends of the guide plate are provided with connecting seats, the inner side of each connecting seat is provided with a reinforcing plate, and each reinforcing plate is provided with a connecting shaft. The connecting shaft passes through the corresponding connecting seat and the waist-shaped hole in sequence and is fixedly connected to the corresponding shaft seat.

[0009] Preferably, the bearing seat is provided with a T-shaped hole, and the rear end of the large diameter section of the T-shaped hole is provided with a plurality of threaded blind holes arranged around the small diameter section of the T-shaped hole. A connector is provided in the large diameter section of the T-shaped hole. The connector is fixedly connected to the corresponding threaded blind holes by two bolts.

[0011] The beneficial effects of this utility model are as follows: This utility model provides slots on both sides of the corner of the right-angle feed inlet body, and provides elastic support mechanisms at each slot. The elastic support mechanisms are equipped with guide plates located inside the right-angle feed inlet body. The guide plates are inclined in a front-low and rear-high state. When the guide plates are impacted by materials, the guide plates transmit the impact force to the elastic support mechanisms for buffering and absorption, thereby reducing the impact on the guide plates. Compared with the prior art, it can achieve buffering and shock absorption in the feeding process, thereby improving service life and reducing noise.

[0012] The upper surface of the guide plate is provided with several wear-resistant plates arranged in sequence. The wear-resistant plates are fixedly connected to the guide plate by several screws. The wear-resistant plates further improve the service life of the guide plate, and when the corresponding wear-resistant plate needs to be replaced, the corresponding wear-resistant plate can be replaced individually, reducing the cost of use.

[0019] The elastic support mechanism 2 includes a connecting plate 21, a bearing seat 22, a sliding plate 23, a screw seat 24, a screw 25, a buffer spring 26, an adjusting nut 27, and a support 28. The connecting plate 21 has a waist-shaped hole 29. A sliding plate 23 that closes the waist-shaped hole 29 is slidably provided on the outer side of the connecting plate 21. The sliding plate 23 has a bearing seat 22. The sliding plate 23 has a screw seat 24. The screw seat 24 has a screw 25. The lower end of the screw 25 passes through the support 28 provided on the connecting plate 21. The screw 25 has an adjusting nut 27 located below the support 28. A buffer spring 26 is sleeved on the screw 25 between the screw seat 24 and the support 28. By rotating the screw 25, the screw seat 24 is driven to move downward or upward, thereby compressing or extending the spring and adjusting the buffer force.

[0020] The connecting plate 21 is provided with two guide rails 211 located on the outer sides of both ends of the slide plate 23. The slide plate 23 is provided with two limiting plates 210 located on the corresponding sides of the two guide rails 211. The guide rails 211 guide the movement of the slide plate 23, so that the slide plate 23 can stably fit with the sealing surface or adjust its position, thereby controlling the tension and sealing the waist-shaped hole 29.

[0021] Both ends of the guide plate 3 are provided with connecting seats 6, and the inner side of each connecting seat 6 is provided with a reinforcing plate 7. Each reinforcing plate 7 is provided with a connecting shaft 8. The connecting shaft 8 passes through the corresponding connecting seat 6 and the waist-shaped hole 29 in sequence and is fixedly connected to the corresponding shaft seat 22.

[0024] The working process of this utility model:

[0025] This utility model discloses a feeding inlet device that can mitigate the impact of material entering from the input end of the right-angle feeding inlet body 1. When the material falls and impacts the wear-resistant plate 5, the wear-resistant plate 5 drives the guide plate 3 to move downward under the impact force. The guide plate 3 drives the shaft seat 22 to move downward through the cooperation of the connecting seat 6, the reinforcing plate 7 and the connecting shaft 8. The shaft seat 22 drives the screw seat 24 to move downward through the sliding plate 23. The screw seat 24 exerts a force on the buffer spring 26, causing it to compress and deform, absorbing the transmitted impact, thereby mitigating the impact of the material on the feeding device and reducing the noise generated by the material impact to a certain extent.

[0026] When the angle of the guide plate 3 needs to be adjusted, loosen the bolt 215 to remove it from the corresponding threaded blind hole 213, and then move the bolt 215 to drive the connecting body 214 to rotate. The connecting body 214 drives the connecting shaft 8 to rotate through the cooperation of the plug body 216 and the plug groove 9. The connecting shaft 8 drives the connecting seat 6 to rotate through the reinforcing plate 7. The connecting seat 6 drives the guide plate 3 to rotate to adjust the tilt angle. After the adjustment is completed, screw the bolt 215 into the corresponding threaded blind hole 213.

[0027] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
