Description

Technical Field

[0001] The utility model relates to an automatic lifting and feeding mechanism. Background Art

[0002] There is a process in the production of carbon molecular sieves that requires the material to be lifted to a high buffer silo through an elevator bucket, and then discharged from the buffer silo into the carbonization furnace. The specific process is that when the paddle-type material level switch in the buffer silo senses that the buffer silo is insufficient, the alarm light sounds. At this time, the operator manually turns on the belt conveyor to transport the material to the elevator bucket. When the elevator bucket is full, the belt conveyor is manually turned off, and the winch hoist switch is turned on to run the elevator bucket to a near-high point. At this time, the winch switch is activated to pour the material in the elevator bucket into the buffer silo. The tilt angle of the elevator bucket is observed in real time to prevent the elevator bucket from being unable to descend due to excessive tilt angle and excessive wire tension from causing wire rope breakage and damage to the winch hoist.

[0003] This will require the operator to continuously monitor the feeding mechanism, which not only wastes human resources, but also requires the operator to have operating experience. Otherwise, the buffer silo will be full while the lifting bucket is continuously discharging material, or the material in the buffer silo will be consumed and idling, while the lifting bucket has not yet reached the discharging position, affecting the operation of the equipment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an automatic lifting and loading mechanism, which aims to realize automatic lifting of materials, eliminate the need for manual monitoring, reduce the risk of material transportation, and improve the accuracy and stability of material discharge.

[0005] To solve the above technical problems, the technical solution of the utility model is: an automatic lifting and loading mechanism, comprising a hoist, a buffer silo, a lifting track, a lifting bucket, a belt conveyor and a mechanism bracket; the hoist is located on the top of the mechanism bracket, connected to the lifting bucket, and provides lifting power for the lifting bucket; the lifting track is located on the mechanism bracket and on one side of the hoist, arranged upwardly and inclined, with the bottom located on one side of the belt conveyor and the top located on one side of the buffer silo, and the lifting bucket moves freely on the lifting track;

[0006] The buffer silo is provided with a rotary material level switch, which is electrically connected to the winch elevator. It is located inside the buffer silo and senses the material capacity in the buffer silo. When the capacity is lower than the standard, the winch elevator is started to lift the lifting bucket to the top of the buffer silo for discharge.

[0007] Furthermore, an upper limit switch is provided on the top of the lifting track. The upper limit switch controls the lifting bucket to stop lifting when it approaches the buffer silo. At this time, the winch elevator continues to lift the lifting bucket, and the bucket body is actually tilted to achieve material discharge.

[0008] Furthermore, an arc track is provided at the upper limit switch above the lifting track to provide a trajectory limit for the lifting bucket to slowly dump materials.

[0009] Furthermore, a lower limit switch is provided at the bottom of the lifting track, and the lower limit switch controls the lifting bucket to descend to the belt conveyor and stop, and the material is loaded through the belt conveyor.

[0010] Furthermore, the upper limit switch or the lower limit switch may be a mechanical switch or a photoelectric induction switch.

[0011] Furthermore, a photoelectric material level switch is provided on one side of the belt conveyor. The photoelectric material level switch adopts a photoelectric sensor to sense the material capacity in the lifting bucket, thereby controlling the material transportation of the belt conveyor.

[0012] Furthermore, a lifting guide wheel is provided on one side of the hoisting hoist for carrying the lifting cable to improve the transportation stability of the lifting bucket.

[0013] Furthermore, a safety guardrail is provided at the bottom of the lifting track. The safety guardrail is located on one side of the belt conveyor to protect the space above the lifting bucket and prevent safety hazards caused by human operation.

[0014] Compared with the existing technology, the utility model provides an automatic lifting and loading mechanism with an overall structure that is automatically operated, which can effectively save manpower, eliminate manual operation errors, and improve work efficiency. The end of the track is in an arc shape, and the hopper will not get stuck when moving up and down. There is a guardrail under the track to prevent the hopper from falling on people when the wire rope breaks. There is a rotary material level switch in the buffer silo. When there is insufficient material, the rotary switch works, outputs a signal alarm, and the lifting hopper starts working. When the lifting hopper is at the bottom, the photoelectric material level switch starts working. When material is detected, the conveyor belt transports the material to the lifting hopper. When the photoelectric material level detects the presence of material, the conveyor belt stops transporting the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In one embodiment, Figure 1-3 As shown, an automatic lifting and loading mechanism includes a hoist 1, a buffer silo 4, a lifting track 6, a lifting bucket 7, a belt conveyor 11 and a mechanism bracket 12; the hoist 1 is located on the top of the mechanism bracket 12, connected to the lifting bucket 7, and provides lifting power for the lifting bucket 7; the lifting track 6 is located on the mechanism bracket 12 and on one side of the hoist 1, and is arranged upwardly with its bottom located on one side of the belt conveyor 11 and its top located on one side of the buffer silo 4. The lifting bucket 7 moves freely on the lifting track 6;

[0020] The buffer silo 4 is provided with a rotary material level switch 5, which is electrically connected to the winch elevator 1. It is located inside the buffer silo 4 and senses the material capacity in the buffer silo 4. When the capacity is lower than the standard, the winch elevator 1 is started to lift the lifting bucket 7 to the top of the buffer silo 4 for discharge.

[0021] Furthermore, an upper limit switch 3 is provided on the top of the lifting track 6. The upper limit switch 3 controls the lifting bucket 7 to stop lifting when it approaches the buffer silo 4. At this time, the winch elevator 1 continues to lift the lifting bucket 7, and the bucket body is actually tilted to achieve material discharge.

[0022] Furthermore, an arc track is provided at the upper limit switch 3 above the lifting track 6 to provide a trajectory restriction for the lifting bucket 7 to slowly dump materials.

[0023] Furthermore, a lower limit switch 10 is provided at the bottom of the lifting track 6 , and the lower limit switch 10 controls the lifting bucket 7 to descend to the belt conveyor 11 and stop, and the material is loaded through the belt conveyor 11 .

[0024] Furthermore, the upper limit switch 3 or the lower limit switch 10 may be a mechanical switch or a photoelectric induction switch.

[0025] Furthermore, a photoelectric material level switch 9 is provided on one side of the belt conveyor 11 . The photoelectric material level switch 9 uses a photoelectric sensor to sense the material capacity in the lifting bucket 7 , thereby controlling the material transportation of the belt conveyor 11 .

[0026] Furthermore, a lifting guide wheel 2 is provided on one side of the hoisting hoist 1 for carrying the lifting cable to improve the transportation stability of the lifting bucket 7.

[0027] Furthermore, a safety guardrail 8 is provided at the bottom of the lifting track 6. The safety guardrail 8 is located on one side of the belt conveyor 11 to protect the space above the lifting bucket 7 and prevent safety hazards caused by human operation.

[0028] Belt conveyor 11 is activated to transport material into bucket 7. When photoelectric level switch 9 senses that bucket 7 is full, belt conveyor 11 automatically shuts down. When rotary level switch 5 senses insufficient material in buffer silo 4, winch 1 starts, using guide wheel 2 to lift bucket 7 upward along lifting track 6 using a wire rope. When bucket 7 reaches the top of track 6 and encounters upper limit switch 3, winch 1 stops ascending. Bucket 7 is tilted over the arc-shaped track above track 6, pouring the material into buffer silo 4. Once dumped, bucket 7 automatically begins descending. Upon reaching the bottom of track 6, it encounters lower limit switch 10 and stops descending. Belt conveyor 11 then automatically begins conveying material into bucket 7. Safety guardrail 8 provides safety during the upward and downward movements of bucket 7. A programmable controller controls each action, ensuring continuous, 24-hour operation.

[0029] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by ordinary technicians in this field based on the above-mentioned conception without creative work are all within the protection scope of the present invention.
