Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, specifically to a bucket elevator with easily replaceable buckets. Background Technology

[0002] Bucket elevators, also known as bucket conveyors, are a widely used type of mechanical conveying equipment. Their working principle is that a traction belt is wrapped around the head wheel and the bottom wheel, and the buckets are fixed on the traction belt at a certain distance. The outer shell seals the buckets and the traction belt. The material enters the moving bucket from the base, is lifted along the barrel, and is thrown out of the bucket at the head of the machine and discharged outside the machine through the discharge pipe.

[0003] The existing bucket elevators have the following problems during use:

[0004] 1. The buckets in existing bucket elevators are usually fixed to the outside of the traction belt using clamps and multiple sets of bolts. When replacing them, multiple sets of bolts need to be removed, which is quite troublesome. Moreover, repeated disassembly and reassembly can easily cause stripping at the connection, affecting the stability of the bucket installation.

[0005] 2. The upper part of the hopper is fixedly installed on the outside of the traction belt. The hopper port is adjusted with the angle of the traction belt. When the hopper moves to the upper side of the top conveyor wheel of the machine head at the connection point of the hopper and the traction belt, the hopper rotates to the lateral angle. At this time, the material in the hopper begins to slide and be discharged. Some of the material in the hopper is easy to spill to the outside of the traction belt. Since there is space for the hopper to pass through between the discharge pipe and the traction belt, it is easy to cause a large amount of material leakage.

[0006] To address the aforementioned technical problems, this application proposes a bucket elevator with easily replaceable hoppers. Utility Model Content

[0007] I. Technical problems to be solved

[0008] The technical problem this utility model aims to solve is that the hopper is usually fixed to the outside of the traction belt using a snap-fit ​​interface and multiple sets of bolts, which makes disassembly relatively troublesome. The stability of the hopper installation is also a concern. When the upper part of the hopper is fixed to the outside of the traction belt and the connection between the hopper and the traction belt moves to the top of the top conveyor wheel of the machine head, the hopper rotates to a lateral angle, and the material begins to slide and be discharged, which can easily cause a large amount of material leakage.

[0009] II. Technical Solution

[0010] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a bucket elevator with an easy-to-replace bucket, including a shell, with a rotating wheel rotatably installed on the upper and lower sides inside the shell, a motor connected to a set of rotating wheels installed on the outer side of the shell, and a conveyor belt sleeved on the outer side of the two sets of rotating wheels;

[0011] Multiple sets of hoppers are installed on the outside of the conveyor belt, and a rotating connection assembly and a limiting assembly are connected between the hoppers and the outside of the conveyor belt.

[0012] The rotating connection assembly includes a U-shaped frame, a connecting shaft, and a sleeve. The U-shaped frame is fixedly installed on the outside of the conveyor belt, and the sleeve is fixedly installed on the upper outer wall of the hopper. The sleeve passes through the inner U-shaped frame and the connecting shaft 802 passes through it, thus rotatably connecting the upper side wall of the hopper to the outside of the conveyor belt.

[0013] The limiting component includes a U-shaped frame II and a limiting slide bar. The U-shaped frame II is rotatably mounted on the outside of the conveyor belt, and the limiting slide bar is mounted on the outside of the bottom of the hopper. The inner sides of the two side walls of the U-shaped frame II are respectively provided with limiting slides that cooperate with the limiting slide bar to slide through, thereby limiting the bottom of the hopper.

[0014] As an improvement, a limit block is installed at the head end of the connecting shaft, and a nut is fitted on the outer side of the tail end of the connecting shaft and connected by threads.

[0015] As an improvement, a positioning block is installed at the bottom of the hopper, and the limiting slide rod passes through and is installed inside the positioning block.

[0016] As an improvement, a connecting slide rod slides through the side wall of the limiting slide away from the conveyor belt. A baffle is fixedly installed on the outer side of the connecting slide rod located inside the limiting slide. Multiple sets of springs are installed between the baffle and the side wall of the limiting slide away from the conveyor belt. Through holes are provided at both ends of the limiting slide rod to allow the connecting slide rod to pass through.

[0017] As an improvement, the outer shell is a U-shaped structure and is assembled from multiple components. A feeding groove is connected to the lower part of one side wall of the outer shell, and a discharge groove is connected to the upper part of the other side wall of the outer shell. The lower side wall of the feeding groove and the discharge groove connected to the outer shell respectively extends to the inside of the outer shell.

[0018] As an improvement, the hopper has an integrally formed discharge trough on the side closest to the conveyor belt.

[0019] As an improvement, the outer sides of the two sets of rollers are connected to the inner side of the conveyor belt by meshing teeth.

[0020] III. Beneficial Effects

[0021] The advantages of this utility model compared with the prior art are: the upper part of the hopper is rotatably connected to the conveyor belt by a connecting shaft passing through the U-shaped frame and the sleeve respectively, which is easy to disassemble later.

[0022] The bottom of the hopper is limited by a limiting component. When the hopper moves to the top of the conveyor wheel, the bottom of the hopper is limited by the limiting component, causing the hopper opening to tilt upwards at an angle. This prevents the hopper from spilling material while it is on the top of the conveyor wheel. When the hopper moves downwards from the top of the conveyor wheel, it is limited by the limiting component, causing the hopper opening to tilt downwards at an angle. Combined with centrifugal force, the material can be discharged a longer distance along the inclined side wall of the hopper, ensuring that the material can enter the discharge chute and reducing material leakage.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] As attached Figure 1 and attached Figure 2 As shown, a bucket elevator with easily replaceable hoppers includes a housing 1, which is a U-shaped structure assembled from multiple components. Inside the housing 1, upper and lower sides are respectively rotatably mounted with rollers 4. On the outer side of the housing 1, a motor 5 connected to a set of rollers 4 is mounted, driving the rollers 4 to rotate. A conveyor belt 6 is fitted around the outer sides of the two sets of rollers 4. The outer sides of the two sets of rollers 4 are connected to the inner sides of the conveyor belt 6 by meshing teeth to prevent the conveyor belt 6 from slipping on the outer sides of the rollers 4. Multiple sets of hoppers 7 are mounted on the outer side of the conveyor belt 6. The rotation of the conveyor belt 6 drives the multiple sets of hoppers 7 to reciprocate within the housing 1.

[0032] As attached Figure 2 and attached Figure 3 As shown, a feeding chute 2 is connected to the lower part of one side wall of the outer shell 1, and a discharging chute 3 is connected to the upper part of the other side wall of the outer shell 1. The lower side walls of the feeding chute 2 and the discharging chute 3 connected to the outer shell 1 respectively extend to the inner side of the outer shell 1. Material is fed into the lower inner side of the outer shell 1 through the feeding chute 2. The material falls into multiple sets of hoppers 7 and is conveyed upward through the hoppers 7. The lower side wall of the discharging chute 3 is located below a set of upper rotating wheels 4. A discharge chute 10 is integrally formed on the side of the hopper 7 near the conveyor belt 6. When the hopper 7 is tilted at the top of the rotating wheel 4, the discharge path is extended through the discharge chute 10 to facilitate the discharge of material into the discharging chute 3. When the bottom of the hopper 7 moves to the side of the conveyor belt 6, the discharge chute 10 rotates to be close to the conveyor belt 6 and will not contact the lower side wall of the discharging chute 3.

[0033] A rotating connection assembly 8 and a limiting assembly 9 are connected between the hopper 7 and the outer side of the conveyor belt 6.

[0034] As attached Figure 4 and attached Figure 5 As shown, the rotating connection assembly 8 includes a U-shaped frame 801, a connecting shaft 802, and a sleeve 804. The U-shaped frame 801 is fixedly installed on the outside of the conveyor belt 6, and the sleeve 804 is fixedly installed on the upper outer wall of the hopper 7. The sleeve 804 passes through the inner U-shaped frame 801 and the connecting shaft 802 passes through it. A limit block is installed at the head end of the connecting shaft 802, and a nut 803 is fitted on the outer side of the tail end of the connecting shaft 802. The nut 803 is threaded to rotately connect the upper side wall of the hopper 7 to the outside of the conveyor belt 6. The nut 803 can be removed later to facilitate the disassembly of the hopper 7.

[0035] As attached Figure 4 and attached Figure 6As shown, the limiting component 9 includes a U-shaped frame 901 and a limiting slide rod 908. The U-shaped frame 901 is rotatably mounted on the outside of the conveyor belt 6. A positioning block 907 is installed at the bottom of the hopper 7. The limiting slide rod 908 passes through and is installed inside the positioning block 907. The limiting slide rod 908 is installed on the outside of the bottom of the hopper 7. The inner sides of the two side walls of the U-shaped frame 901 are respectively provided with limiting slides 902 that cooperate with the limiting slide rod 908 to slide through. By sliding the limiting slide rod 908 through the limiting slides 902, the bottom of the hopper 7 is limited.

[0036] A connecting slide rod 903 slides through the side wall of the limiting slide 902 away from the conveyor belt 6. A baffle 904 is fixedly installed on the outer side of the portion of the connecting slide rod 903 located inside the limiting slide 902. Multiple sets of springs 906 are installed between the baffle 904 and the side wall of the limiting slide 902 away from the conveyor belt 6. The limiting slide rod 908 has through holes 905 at both ends to allow the connecting slide rod 903 to pass through. When the baffle 904 is pushed to the side away from the conveyor belt 6, the limiting slide rod 908 passes through the inside of the limiting slide 902, and the connecting slide rod 903 passes through the through hole 905 on the limiting slide rod 908. When the baffle 904 is released, the limiting slide rod 908 is pushed to slide towards the conveyor belt 6 inside the limiting slide 902 by the rebound force of the springs 906, thus completing the limiting connection between the bottom of the hopper 7 and the conveyor belt 6.

[0037] When the bucket elevator is feeding material, after receiving the material, the bucket 7 moves with the conveyor belt 6 to the outer part of the upper set of rollers 4. When the rollers 4 are on the rising side, the upper part of the bucket 7 moves with the conveyor belt 6. The bottom of the bucket 7 is limited by the U-shaped frame 901 and tilts. At this time, the opening side of the bucket 7 faces diagonally upward, and the material will not spill out. When the bucket 7 is on the falling side of the rollers 4, the rebound force of the spring 906 drives the bottom of the bucket 7 to approach the conveyor belt 6, prolonging the tilting time of the bucket 7. With the help of the discharge chute 10, the material can be sent to the discharge chute 3 for discharge, reducing material leakage.
