Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to an elevator bucket cleaning mechanism. Background Technology

[0002] Elevators are commonly used equipment for vertical material conveying, using cyclically moving buckets to lift and unload materials from a low position. In existing technologies, material residue often remains after unloading. This residue not only reduces the effective loading volume for subsequent loading and affects conveying efficiency, but can also cause cross-contamination when conveying different materials. Furthermore, cleaning residue usually requires manual intervention after machine shutdown, which is time-consuming and labor-intensive. Moreover, existing elevator unloading mechanisms are typically fixed or difficult to adjust, making it impossible to flexibly control the unloading process at specific locations according to actual production needs, thus limiting the application scenarios and operational flexibility of elevators.

[0003] Therefore, this application provides a bucket cleaning mechanism for a hoist to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a bucket cleaning mechanism for a hoist, which aims to solve the problem that material residue often remains in the bucket after unloading. The residual material not only reduces the effective volume of subsequent loading and affects the conveying efficiency, but may also cause cross-contamination when conveying different materials. Moreover, cleaning the residue usually requires manual operation after stopping the machine, which is time-consuming and labor-intensive. Furthermore, the existing unloading mechanisms of hoists are usually fixed or inconvenient to adjust, which makes it impossible to flexibly control the unloading process at specific locations according to actual production needs, thus limiting the application scenarios and operational flexibility of the hoist.

[0006] Preferably, the air knife assembly further includes a cleaning air knife and a mounting rod. The two ends of the mounting rod are fixed to the front and rear side walls of the discharge channel. The cleaning air knife is mounted on the mounting rod and is located on the left side of the unloading assembly, ensuring that the cleaning air knife can be stably installed in the predetermined position within the discharge channel.

[0007] Preferably, the air outlet of the cleaning air knife is set at an upward angle, and the angle of the air outlet is adapted to the bucket after unloading. This upward angle design of the air outlet ensures that the airflow can be effectively blown into and clean the inside of the bucket after unloading.

[0008] Preferably, the unloading assembly further includes guide columns and a sliding plate. The sliding plate slides on the guide columns. There are two sets of guide columns, symmetrically arranged at both ends of the sliding plate. The guide columns are fixed to the outer wall of the discharge channel by fixing buckles. The sliding plate is connected to a connecting plate by a connecting rod. A guide groove for the connecting rod to slide up and down is opened on the outer wall of the discharge channel. The connecting plate is connected to an unloading guide plate for tipping the bucket by a connecting piece. Through the cooperation of the guide columns, the sliding plate and the linkage mechanism, the unloading guide plate can slide up and down stably and reliably.

[0009] Preferably, the bucket is connected to a guide wheel, the unloading guide plate is located below the guide wheel, and the electric push rod is connected to the sliding plate.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, a cleaning air knife is installed after the unloading position to automatically blow the inside of the bucket after unloading, effectively removing residual materials, avoiding the impact of material accumulation on conveying efficiency and cross-contamination between different materials, reducing the need for manual cleaning, and improving production efficiency and cleanliness.

[0012] In this invention, the unloading guide plate is driven to rise and fall by an electric push rod, which can conveniently control whether the unloading guide plate enters the movement trajectory of the bucket guide wheel, thereby achieving selective unloading. Operators can easily control whether to unload according to their needs, greatly enhancing the operational flexibility and adaptability of the elevator under different working conditions.

[0019] 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. Example

[0020] refer to Figure 1-4 The illustrated bucket cleaning mechanism for a hoist includes a hoist body 1, which further includes a conveying channel 2 and a discharge channel 3. The discharge channel 3 is connected below the conveying channel 2. Buckets 9 are connected to the conveying channel 2 via a conveying chain. Multiple sets of buckets 9 are provided. The conveying chain is driven by a motor. A discharge assembly 4 for unloading materials from the buckets 9 and an air knife assembly 5 for cleaning the buckets 9 are connected to the discharge channel 3. The air knife assembly 5 is located to the left of the discharge assembly 4. To facilitate the operation of the air knife assembly 5, it also includes a cleaning air knife 6 and a mounting rod 7. Both ends of the mounting rod 7 are fixed to... On the front and rear side walls of the discharge channel 3, cleaning air knives 6 are installed on the mounting rods 7. The cleaning air knives 6 are located on the left side of the unloading assembly 4. After the hopper 9 has finished unloading through the unloading assembly 4, it will move over the cleaning air knives 6 via the conveyor chain. The air outlet of the cleaning air knives 6 is set at an upward angle. The angle of the air outlet of the cleaning air knives 6 is adapted to the hopper 9 after unloading, so that the cleaning direction of the cleaning air knives 6 and the moving direction of the hopper 9 are intersected. After unloading, the hopper 9 is cleaned of the residual material inside by the cleaning air knives 6. The conveying channel 2 is connected to an observation window 18 for observing the inside of the channel.

[0021] In one embodiment of this invention, to facilitate more convenient and faster control of the unloading conveying channel 2 of the bucket 9, an electric push rod 17 is connected to drive the unloading assembly 4 to move up and down. The electric push rod 17 is connected to the conveying channel 2 via a mounting plate 16, and a guide wheel 91 is connected to the bucket 9. The unloading guide plate 8 is located below the guide wheel 91. The unloading assembly 4 also includes a guide column 13 and a sliding plate 14. The electric push rod 17 is connected to the sliding plate 14, allowing the equipment to easily control whether the bucket 9 unloads material when passing through the discharge channel 3 via the electric push rod 17. To make the up-and-down movement of the unloading guide plate 8 more stable, the sliding plate 14 slides on the guide column 13. Two sets of guide columns 13 are provided. Symmetrically arranged at both ends of the sliding plate 14, the guide post 13 is fixed to the outer wall of the discharge channel 3 by the fixing buckle 15. The sliding plate 14 is connected to the connecting plate 10 by the connecting rod 12. The outer wall of the discharge channel 3 is provided with a guide groove for the connecting rod 12 to slide up and down. The connecting plate 10 is connected to the unloading guide plate 8 for tipping the bucket 9 by the connecting piece 11. The unloading guide plate 8 has a trapezoidal cross section, so that when the bucket 9 passes from right to left through the unloading guide plate 8 after being lifted by the electric push rod 17 under the action of the conveyor chain, the material in the bucket 9 can be unloaded into the discharge channel 3. When it passes the left end of the unloading guide plate 8, the residual material in the bucket 9 is cleaned by the cleaning air knife 6.

[0022] The working principle of this utility model is as follows: During operation, the operator first controls the electric push rod 17 to move the sliding plate 14 upwards on the guide column 13. This causes the sliding plate 14 to move the unloading guide plate 8 upwards via the connecting rod 12, positioning the unloading guide plate 8 on the trajectory of the guide wheel 91 of the bucket 9. Then, the cleaning air knife 6 is activated. Afterwards, the operator can use external equipment to load the material to be transferred into the bucket 9 inside the main body 1 of the elevator. Under the action of the motor-driven conveyor chain, the bucket 9 transfers the material along the conveyor chain. When the guide wheel 91 of the bucket 9 passes the unloading guide plate 8, the bucket 9, moving from right to left, passes the unloading guide plate 8 after being lifted by the electric push rod 17. The material in the bucket 9 is then unloaded into the discharge channel 3. When passing the left end of the unloading guide plate 8, the residual material in the bucket 9 is cleaned by the cleaning air knife 6.
