Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, and particularly relates to an anti-blocking bucket elevator. Background Art

[0002] A bucket elevator is a continuous conveying device widely used for vertically or obliquely conveying powdery, granular, and small-block bulk materials. It mainly consists of key components such as a driving device, a head component, an intermediate section component, a bottom component, a transmission component, and a hopper.

[0003] For example, the Chinese utility model patent disclosed with the publication number CN219340781U: an anti-blocking bucket elevator. This application includes a first feed box, in which a lifting device, a discharging device, and a feeding device are provided. The feeding device includes a feeding hopper, a blanking channel, a feeding channel, a rotating cylinder, and a first motor. One end of the feeding channel communicates with the first feed box, and the other end is connected to the blanking channel. When feeding, materials can be directly poured into the feeding hopper manually, the rotating cylinder is driven to rotate by the first motor, and the materials in the feeding hopper are transferred into the blanking channel through the material grooves on the rotating cylinder, so that the feeding speed can be controlled by controlling the rotation speed of the first motor, thereby realizing the anti-blocking function of feeding. However, since the bucket elevator can convey powdery, granular, and small-block bulk materials, the lifting buckets inside the bucket elevator will continuously shovel and lift the materials in the first feed box. In order to avoid continuous friction with the inner wall of the first feed box and increase the wear speed of the equipment, the lifting buckets will keep a certain distance from the inner wall of the first feed box. Therefore, when lifting and conveying some blocky items, there is a certain probability that some blocky items will get stuck between the lifting bucket and the inner wall of the first feed box, which will increase the load of the driving motor and easily cause continuous accumulation of materials in the first feed box and blockage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-blocking bucket elevator, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Feeding hoppers are fixedly installed on both sides of the silo. A driven wheel is movably installed in the silo. A driving wheel is movably installed in the top silo guard. One side of the driving wheel is fixedly connected to the output end of a driving motor outside the top silo guard. A steel wire lifting belt is movably connected between the driving wheel and the driven wheel. A plurality of feeding buckets are arranged on the outer side of the steel wire lifting belt. The feeding buckets are movably installed on the outer side of the steel wire lifting belt through connectors. The connector comprises a fixed seat and a connecting seat. The fixed seat is fixedly installed on the outer side of the steel wire lifting belt through a plurality of fixing screws. The connecting seat is fixedly installed on one side of the feeding bucket. And the fixed seat and the connecting seat are movably connected to each other.

[0007] As a further preferred embodiment of the present utility model, a plurality of positioning seats are fixedly installed on the outer side of the steel wire lifting belt. A communicating first counterbore is provided in the positioning seat and the steel wire lifting belt.

[0008] Based on this, arranging a plurality of positioning seats on the outer side of the steel wire lifting belt can provide a positioning function for the installation of the fixed seat.

[0009] As a further preferred embodiment of the present utility model, a positioning groove is provided on one side of the fixed seat. A first displacement groove is provided on the other side of the fixed seat. The fixed seat is inserted and installed on the corresponding positioning seat through the positioning groove.

[0010] As a further preferred embodiment of the present utility model, one end of the fixing screw passes through the corresponding first counterbore, the positioning groove and the first displacement groove and extends to one side of the fixed seat. A first nut is threadedly connected to the fixing screw on one side inside the first displacement groove.

[0011] As a further preferred embodiment of the present utility model, a plurality of screw grooves are provided on one side of the connecting seat. A plurality of second counterbores are provided on the other side of the connecting seat. One side of the connecting seat is inserted and installed in the first displacement groove. And one end of the fixing screw also passes through the second counterbore and extends into the screw groove and is threadedly connected to a second nut. A compression spring is sleeved on the fixing screw between one side inside the first displacement groove and the connecting seat.

[0012] Based on this, the fixed seat is fixedly installed on the outer side of the steel wire lifting belt through the fixing screw, and the connecting seat can be movably installed in the first displacement groove at the same time.

[0013] As a further preferred embodiment of the present utility model, a plurality of fixing screws are inserted and installed on one side of the feeding bucket. A second displacement groove is provided in the fixing screw. One end of the fixing screw is threadedly connected in the corresponding screw groove. That is, the feeding bucket is fixedly installed on one side of the connecting seat through a plurality of fixing screws.

[0014] Based on this, after the feeding hopper is fixedly installed on one side of the connecting seat, when the material in the silo gets stuck between the feeding hopper and the inner wall of the silo, the feeding hopper can be forced to squeeze and move the connecting seat into the first displacement groove, thereby preventing the feeding hopper from getting stuck and causing blockage in the silo.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, the feeding hopper is movably installed outside the steel wire lifting belt through a connector, and the connector is composed of components such as a fixed seat, a connecting seat, a fixing screw, and a compression spring. When the bulk material gets stuck between the feeding hopper and the inner wall of the silo, the steel wire lifting belt drives the feeding hopper to continuously operate. As a result, after the feeding hopper is subjected to the resistance of the bulk material, the connecting seat is squeezed and displaced into the first displacement groove, which can increase the distance between the feeding hopper and the inner wall of the silo, solve the problem of the feeding hopper getting stuck, and prevent material accumulation and blockage in the silo.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes, and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0024] Such as Figures 1 - 5As shown in the figure, a clogging-proof bucket elevator provided by the utility model includes a feed bin 1 and a top bin guard 4. Two intermediate bins 3 are fixedly connected between the feed bin 1 and the top bin guard 4. Feeding hoppers 2 are fixedly installed on both sides of the feed bin 1. A driven wheel 6 is movably installed in the feed bin 1. A driving wheel 5 is movably installed in the top bin guard 4. One side of the driving wheel 5 is fixedly connected to the output end of a driving motor outside the top bin guard 4. A steel wire lifting belt 7 is movably connected between the driving wheel 5 and the driven wheel 6. A plurality of feeding buckets 8 are arranged on the outer side of the steel wire lifting belt 7. The feeding buckets 8 are movably installed on the outer side of the steel wire lifting belt 7 through connectors 9. The connector 9 includes a fixed seat 11 and a connecting seat 12. The fixed seat 11 is fixedly installed on the outer side of the steel wire lifting belt 7 through a plurality of fixing screws 13. The connecting seat 12 is fixedly installed on one side of the feeding bucket 8. The fixed seat 11 and the connecting seat 12 are movably connected to each other.

[0025] As Figure 4 shown, a plurality of positioning seats 14 are fixedly installed on the outer side of the steel wire lifting belt 7. A communicating first counterbore 15 is formed in the positioning seat 14 and the steel wire lifting belt 7. Arranging a plurality of positioning seats 14 on the outer side of the steel wire lifting belt 7 can provide a positioning function for the installation of the fixed seat 11;

[0026] As Figures 2 - 5 shown, a positioning groove 16 is formed on one side of the fixed seat 11, and a first displacement groove 17 is formed on the other side of the fixed seat 11. The fixed seat 11 is inserted and installed on the corresponding positioning seat 14 through the positioning groove 16. One end of the fixing screw 13 passes through the corresponding first counterbore 15, the positioning groove 16, and the first displacement groove 17 and extends to one side of the fixed seat 11. A first nut 20 is threadedly connected to the fixing screw 13 on one side located in the first displacement groove 17. A plurality of screw grooves 18 are formed on one side of the connecting seat 12, and a plurality of second counterbores 19 are formed on the other side of the connecting seat 12. One side of the connecting seat 12 is inserted and installed in the first displacement groove 17. One end of the fixing screw 13 also passes through the second counterbore 19 and extends into the screw groove 18 and is threadedly connected to a second nut 23. A compression spring 21 is sleeved on the fixing screw 13 between one side located in the first displacement groove 17 and the connecting seat 12. The fixed seat 11 is fixedly installed on the outer side of the steel wire lifting belt 7 through the fixing screw 13, and the connecting seat 12 can be movably installed in the first displacement groove 17 at the same time. A plurality of fixing screws 10 are inserted and installed on one side of the feeding bucket 8. A second displacement groove 22 is formed in the fixing screw 10. One end of the fixing screw 10 is threadedly connected to the corresponding screw groove 18. That is, the feeding bucket 8 is fixedly installed on one side of the connecting seat 12 through a plurality of fixing screws 10. After the feeding bucket 8 is fixedly installed on one side of the connecting seat 12, when the material in the feed bin 1 gets stuck between the feeding bucket 8 and the inner wall of the feed bin 1, the feeding bucket 8 can be forced to squeeze and move the connecting seat 12 into the first displacement groove 17, thereby preventing the feeding bucket 8 from getting stuck and causing clogging in the feed bin 1.

[0027] It should be noted that the present utility model is an anti-clogging bucket elevator. When installing the feeding bucket 8, the fixed seat 11 can be first inserted and installed on the corresponding positioning seat 14 through the positioning groove 16 on one side. Subsequently, one end of a fixing screw 13 passes through the corresponding first counterbore 15 and the through hole on one side in the positioning groove 16 in sequence and extends to one side of the fixed seat 11, and a first nut 20 is threadedly connected to the fixing screw 13 located in the first displacement groove 17. Then, the remaining two fixing screws 13 are operated in the same way as above, and the installation of the fixed seat 11 can be completed. Then, compression springs 21 are sleeved on the outer sides of the three fixing screws 13 respectively, and one side of the connecting seat 12 is inserted and installed in the fixed seat 11 through the second counterbore 19, and one end of the three fixing screws 13 also passes through the second counterbore 19 and extends into the thread groove 18 respectively. Then, a second nut 23 is threadedly connected to one end of the fixing screw 13 located in the thread groove 18 through the thread groove 18, so as to complete the movable installation of the connecting seat 12. Finally, the feeding bucket 8 is fixedly installed on one side of the connecting seat 12 through a plurality of fixing screws 10;

[0028] When the wire lifting belt 7 drives the feeding bucket 8 to move into the bin 1 and the bulk material in the bin 1 gets stuck between the feeding bucket 8 and the inner wall of the bin 1, since the wire lifting belt 7 will continue to apply a displacement force to the feeding bucket 8, the feeding bucket 8 will move towards the corresponding fixed seat 11 due to the force of the wire lifting belt 7 and the resistance of the bulk material, so that the feeding bucket 8 squeezes and moves the connecting seat 12 in the first displacement groove 17 and compresses the compression spring 21. Then, the distance between the feeding bucket 8 and the inner wall of the bin 1 increases, and the feeding bucket 8 can continue to move in a cycle through the wire lifting belt 7. Subsequently, with the help of the stretching and rebounding force of the compression spring 21, the feeding bucket 8 can be reset in cooperation with the connecting seat 12.
