Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mining slagging-off machines, and particularly discloses a mining slagging-off device. BACKGROUND

[0002] In the field of mining and the like, a slagging-off device is an important operation equipment, which is mainly used for collecting and transporting slag. A typical existing slagging-off device usually integrates an internal conveyor (such as a scraper conveyor), and the working process is that the collected slag is continuously lifted by the conveyor and transported into a cooperating truck hopper.

[0003] However, this traditional unloading mode has a significant defect: the relative position of the discharge port of the conveyor and the hopper is usually fixed. This means that, during the unloading process, all the slag is continuously poured into the same fixed area of the hopper. This directly leads to the rapid accumulation of the slag in the hopper into a "mountain" shape, and the surrounding and corner areas of the hopper cannot be effectively utilized.

[0004] Due to this inherent design limitation, the existing slagging-off device itself cannot autonomously and flexibly change the unloading drop point. Therefore, in actual operation, in order to avoid the problems of serious uneven load, local overload and low space utilization in the hopper, manual intervention is inevitably relied on. That is, after a period of unloading, the construction personnel need to enter the hopper using tools to manually spread the accumulated slag to other idle areas of the hopper. This subsequent spreading process not only greatly increases the labor intensity of the workers, reduces the overall operation efficiency and prolongs the loading time of each truck, but also brings high safety hazards due to the manual operation in the narrow and high hopper. Therefore, the application provides a mining slagging-off device to solve the above-mentioned defects. SUMMARY

[0005] The application aims to solve the problems in the background art and provides a mining slagging-off device, which comprises a slagging-off frame, a slagging-off driving mechanism, a slagging-off front shovel, a conveyor, a sliding beam and a slagging-off bucket. The slagging-off driving mechanism is composed of a hydraulic small arm, a hydraulic large arm and a hydraulic rotating table. The slagging-off bucket is arranged at the front end of the hydraulic small arm. The slagging-off driving mechanism is installed at the front end of the slagging-off frame through a base fixedly connected frame table. The slagging-off front shovel is arranged below the front end of the slagging-off frame. The conveyor is arranged inside the slagging-off frame, and the outer surface of the conveyor is provided with a plurality of groups of wear-resistant plates. The rear end of the slagging-off frame extends to both sides to form an outer contour steel frame. The inner walls of the two groups of outer contour steel frames close to each other are connected with the bottom of the sliding beam through fixedly installed lifting support mechanisms. The upper part of the sliding beam is connected with an arc-shaped bucket through symmetrically arranged adjusting rotating mechanisms. The arc-shaped bucket is provided with a slag pushing mechanism inside. A shovel plate is fixedly installed at the lower end of the arc-shaped bucket.

[0006] In the above technical solution, further, the lifting support mechanism comprises a bottom table fixedly installed on the inner wall of the outer profile steel frame, a lifting hydraulic cylinder fixedly installed above the bottom table, a guide rod vertically installed above the bottom table and close to one side of the lifting hydraulic cylinder, and a sliding beam with one end of the bottom fixedly connected with the telescopic end of the lifting hydraulic cylinder.

[0007] In the above technical solution, further, the adjusting rotating mechanism comprises a mounting bracket fixedly installed on the upper surface of the sliding beam, a rotating hydraulic cylinder fixedly installed on one side of the inner wall of the mounting bracket, a rotating joint arranged at the telescopic end of the rotating hydraulic cylinder, a clamping shaft rotatably installed at one end of the inside of the rotating joint, and a connecting bracket fixedly sleeved on the outside of both sides of the clamping shaft.

[0008] In the above technical solution, further, two reinforcing blocks are fixedly installed on the inner surfaces of the two connecting brackets, and the ends of the two connecting brackets away from the clamping shaft are connected with the outer wall of the arc-shaped bucket.

[0009] In the above technical solution, further, the slag pushing mechanism comprises an L-shaped bracket fixedly installed above the inner wall of the arc-shaped bucket, a motor fixedly installed above the L-shaped bracket, a rotating shaft fixedly installed at the output end of the motor, a spiral pushing blade fixedly installed on the outside of the rotating shaft, a through opening formed in the inner surface of the shovel plate, the end of the rotating shaft extending to below the through opening, and a reinforcing member arranged on the outside of the rotating shaft.

[0010] In the above technical solution, further, the reinforcing member comprises a reinforcing bracket fixedly installed on the inner wall of the arc-shaped bucket and close to below the L-shaped bracket, a bearing embedded in the inside of the reinforcing bracket, and the bearing being sleeved on the outside of the rotating shaft.

[0011] In the above technical solution, further, the arc-shaped bucket is provided with a bracket plate fixedly installed on both sides and close to the upper part of the outer wall of the arc-shaped bucket, a pressurizing hydraulic cylinder fixedly installed on the outer surface of one side of the bracket plate, a pushing bracket fixedly installed at the telescopic end of the pressurizing hydraulic cylinder, and a sliding rod fixedly installed on the outer surface of one side of the pushing bracket.

[0012] In the above technical solution, further, a crushing rod is fixedly installed at the end of the sliding rod away from the pushing bracket, a clamping cylinder is fixedly clamped in the inside of the bracket plate and close to the outside of the sliding rod, and the sliding rod and the clamping cylinder are in sliding connection.

[0015] 2. Under the synergistic action of the adjusting rotating mechanism, the arc-shaped bucket, the shovel plate and the slag pushing mechanism, a continuous and stable forced braking force is provided for slag output. Not only does it ensure smooth and efficient unloading, but it also effectively breaks up the material lumps that are stuck between the arc-shaped shovel and the spiral pushing plate when the slag is shifted, preventing blockage at the discharge port and further ensuring the stability of continuous operation and the working efficiency of the entire device.

[0016] 3. The present application integrates the front end slag collection, the middle section material conveying and the end intelligent material control function into one, forming a continuous and automated operation process. This design greatly optimizes the entire work flow from scraping to loading, significantly reduces equipment waiting and adjustment time, reduces the labor intensity and safety hazards of the operator, and greatly improves the overall operation efficiency.

The muck-removing front shovel 3 is located below the front end of the muck-removing frame 1. The conveyor 4 is located inside the muck-removing frame 1, and the outer surface of the conveyor 4 is provided with multiple sets of wear-resistant plates 30. The rear end of the muck-removing frame 1 extends to both sides with an outer steel frame 5. The inner walls of the two sets of outer steel frames 5 that are close to each other are connected to the bottom of the sliding beam 14 via a fixedly installed lifting support mechanism.

[0034] In this embodiment, the lifting hydraulic cylinder 7 is controlled to extend and retract to control the height of the sliding beam 14 and the space of the turning angle of the arc-shaped bucket 9.

[0035] The guide rod 13 ensures that the sliding beam 14 moves stably during the lifting process, so that the lifting action is stable and accurate.
