Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a mining bin clearing machine based on remote control. Background Art

[0002] The intelligent online clearing system for coal mine water bunkers is a system that uses advanced technology to achieve intelligent management and clearing of coal in coal mine water bunkers. The system uses various sensors and monitoring equipment to monitor the stock, humidity, temperature and other parameters of coal in the water bunker in real time, and realizes online monitoring and analysis of coal through data collection and processing. Once it detects that there is too much coal accumulation in the water bunker or there is an abnormal situation, the system will automatically start the clearing equipment to clean and adjust the coal to ensure the normal stacking and transportation of coal in the water bunker. This intelligent online clearing system can improve the production efficiency of coal mines, reduce manual intervention, and reduce the risk of accidents, thereby effectively ensuring the safety and stability of coal mine production.

[0003] After searching, the Chinese patent with announcement number: CN219296403U discloses a remote control device for a mine cleaning machine. The patent records that a wireless control receiver is used to energize the drive motor with a battery, thereby achieving the effect of remote control, and the diameter of gear two is greater than the diameter of gear four, and the diameter of gear four is greater than that of gear one, so that the rotation speed of the threaded push rod is different from the rotation speed of the stirring blade, so that the pushed mixture is easier to be crushed. When the mechanical collection box is full or needs to be transferred to the next water tank, the door panel is opened through the electric telescopic rod, and then the pump body is started, and the inside of the collection box is flushed through the high-pressure nozzle. Driven by the water flow, the effect of flushing the inside of the collection box is achieved, and the mixture at the bottom of the collection box is conveniently flushed out. When the mechanical cleaning is completed, the pump body is started, the drive motor is turned on, and the threaded push rod and the stirring blade are driven to rotate. Under the action of the high-pressure nozzle, the threaded push rod and the stirring blade are fully flushed to prevent the residue from solidifying for a long time and affecting the next use, thereby achieving the cleaning effect.

[0004] However, the above structure has many problems. Since no screening component is provided, solid particles and impurities will remain in the coal slime, resulting in the product containing substances of different particle sizes and densities, which in turn causes the product to be uneven, bringing adverse effects on subsequent processes and product performance.

DETAILED DESCRIPTION

[0022] like Figure 1-2 As shown, a mining bin cleaning machine based on remote control includes a bin cleaning machine body 1, a conveyor belt 2 is arranged on the bin cleaning machine body 1, a screening frame 3 is arranged above the conveyor belt 2, a fixed frame 4 is arranged on the outside of the screening frame 3, and four corners of the bottom of the fixed frame 4 are fixedly connected with supporting legs 5, and the bottoms of the supporting legs 5 are fixedly connected to the bin cleaning machine body 1, and two slide grooves 6 are symmetrically provided on the inner walls on both sides of the fixed frame 4, and a plurality of fixed columns 7 are symmetrically fixedly connected on the two side walls of the screening frame 3, and the fixed columns 7 are fixedly connected with rollers 8 at one end away from the fixed frame 4, and the rollers 8 are slidably arranged in the corresponding slide grooves 6, and vibration components 9 for making the screening frame 3 reciprocate are arranged on the other two side walls of the fixed frame 4, and a solid-liquid separation component 10 is fixedly installed on the top of the fixed frame 4, and the discharge port of the solid-liquid separation component 10 is located directly above the screening frame 3, and the feed port of the solid-liquid separation component 10 is communicated with the discharge port of the bin cleaning machine body 1.

[0023] When in use, after the bin cleaning machine is started, the coal slime enters the bin cleaning machine body 1, and is then discharged from the discharge port of the bin cleaning machine body 1, and the coal slime will be conveyed to the solid-liquid separation component 10; the solid-liquid separation component 10 immediately starts working to separate the liquid and solid in the material. After the separation is completed, the solid material falls from the discharge port of the solid-liquid separation component 10 and falls into the screening frame 3; at the same time, the vibration component 9 and the conveyor belt 2 are started, and the vibration component 9 on the two side walls of the fixed frame 4 starts to operate, causing the screening frame 3 to produce reciprocating vibration. During the vibration of the screening frame 3, the rollers 8 connected to the fixed columns 7 on the two side walls thereof slide smoothly in the chute 6 on the inner wall of the fixed frame 4, providing a stable guide and support for the vibration of the screening frame 3. Under the influence of the vibration of the screening frame 3, the coal slime falls from the sieve hole of the screening frame 3 and falls onto the conveyor belt 2. The conveyor belt 2 transports the screened coal slime to a designated device for subsequent processing and transportation, while the solid particles and impurities in the coal slime remain in the screening frame 3.

[0024] The entire work process can be operated and monitored through remote control. The operator can flexibly adjust the working parameters of the bin cleaning machine according to the actual conditions, such as the characteristics of the coal slime and the processing requirements, to ensure that the bin cleaning work is carried out efficiently, stably and safely.

[0025] With this design, the vibrating assembly 9 drives the screening frame 3 to reciprocate, thereby being able to quickly screen out solid particles and impurities in the coal slime, thereby improving the quality of the coal slime.

[0026] In addition, through the guide support of the roller 8 and the slide chute 6 and the reasonable design of the vibration component 9, the screening frame 3 vibrates smoothly and equipment failures are reduced.

[0027] The solid-liquid separation component 10 is a prior art component known to those skilled in the art. The structure and principle thereof can be known to those skilled in the art through technical manuals or conventional experimental methods, and therefore will not be described in detail in the embodiments.

[0028] The vibration assembly 9 includes a plurality of elastic expansion members 91 fixedly mounted on one side wall of the screening frame 3 , and the other end of the elastic expansion member 91 is fixedly connected to the inner side wall of the fixing frame 4 .

[0029] A vibration motor 92 is fixedly mounted on a side wall of the fixing frame 4 away from the elastic telescopic member 91 , and an eccentric wheel 93 is fixedly sleeved on the power output shaft of the vibration motor 92 .

[0030] The distance between the power output shaft of the vibration motor 92 and the screening frame 3 is greater than the minimum outer diameter of the eccentric wheel 93 and smaller than the maximum outer diameter of the eccentric wheel 93 .

[0031] A buffer plate 94 is fixedly connected to the screening frame 3 at a position corresponding to the eccentric wheel 93 , and the eccentric wheel 93 is adapted to the buffer plate 94 .

[0032] When in use, after starting the vibration motor 92, the power output shaft drives the eccentric wheel 93 to rotate, and when the protruding portion of the eccentric wheel 93 gradually approaches the buffer plate 94, it will push the buffer plate 94, thereby pushing the screening frame 3 to move in the direction away from the eccentric wheel 93. At this time, the elastic telescopic member 91 connected to the screening frame 3 is squeezed, and as the eccentric wheel 93 continues to rotate, the thrust of the eccentric wheel 93 on the buffer plate 94 gradually decreases, and the elastic telescopic member 91 stretches under the action of its own elastic restoring force, pushing the screening frame 3 back to the direction of the eccentric wheel 93; when the protruding portion of the eccentric wheel 93 turns away from the buffer plate 94, the elastic telescopic member 91 continues to stretch, driving the screening frame 3 to return quickly, and so on and so forth, the eccentric wheel 93 continuously pushes and releases the buffer plate 94, and under the coordinated action of the elastic telescopic member 91, the screening frame 3 realizes reciprocating vibration, thereby effectively screening the material.

[0033] With this design, the eccentric wheel 93 and the elastic telescopic member 91 work together to make the screening frame 3 reciprocate and thereby perform vibration screening on the coal slime, effectively avoiding clogging of the screening holes of the screening frame 3, thereby being able to quickly screen out solid particles and impurities in the coal slime, thereby improving the quality of the coal slime.

[0034] The elastic telescopic component includes a return spring 911 , and two ends of the return spring 911 are fixedly connected to the screening frame 3 and the fixing frame 4 respectively.

[0035] A telescopic rod 912 is arranged inside the return spring 911 , and two ends of the telescopic rod 912 are fixedly connected to the screening frame 3 and the fixing frame 4 respectively.

[0036] With this design, firstly, the reset spring 911 provides the main elastic restoring force, which can quickly push the screening frame 3 back to its original position when the thrust of the eccentric wheel 93 decreases or disappears, thereby ensuring that the reciprocating vibration of the screening frame 3 is continuous and stable; secondly, the telescopic rod 912 inside the reset spring 911 not only plays a guiding and stabilizing role, preventing the reset spring 911 from twisting or deflecting during the telescopic process, but also helps to ensure that the vibration direction of the screening frame 3 always follows the designed path, thereby improving the accuracy and stability of screening; thirdly, the telescopic rod 912 shares part of the pressure, reducing the load borne by the reset spring 911 alone, and reducing the possibility of fatigue damage of the reset spring 911 due to excessive compression.

[0037] The buffer plate 94 is made of elastic material.

[0038] With this design, firstly, when the eccentric wheel 93 contacts the buffer plate 94, the elastic material can absorb and buffer a part of the impact force, thereby reducing the instantaneous strong impact on the screening frame 3 and other components, and reducing the risk of deformation or damage of components due to strong collision.

[0039] Secondly, the vibration and sound generated by the elastic buffer plate 94 when contacting the eccentric wheel 93 are relatively small, which helps to reduce the noise level of the entire equipment during operation.

[0040] Thirdly, the direct hard collision between the eccentric wheel 93 and the rigid components is reduced, the wear degree of the eccentric wheel 93 is reduced, and the service life thereof is extended.

[0041] Fourthly, the rebound characteristics of the elastic buffer plate 94 can enhance the vibration effect of the screening frame 3 to a certain extent and improve the screening efficiency.

[0042] Fifth, the eccentric wheel 93 can be adapted to different rotation speeds and eccentric distances, ensuring good buffering effect under various working conditions.

[0043] In this embodiment, the buffer plate 94 is made of elastic rubber.

[0044] In addition to this example, the buffer plate 94 may also be made of polyurethane, silicone, latex, etc.

[0045] A connecting rod 11 is arranged between two adjacent supporting legs 5 .

[0046] With this design, adjacent supporting legs 5 are connected by connecting rods 11 to form a more stable frame structure, which not only improves the stability of the entire fixing frame 4 and the screening frame 3, but also enables the force between the supporting legs 5 to be more evenly distributed, thereby preventing a certain supporting leg 5 from being subjected to excessive pressure alone; at the same time, it has a certain restraining effect on the supporting legs 5, reducing the bending or twisting deformation of the supporting legs 5 caused by long-term force; in addition, it enhances the overall rigidity of the fixing frame 4, making it less likely to undergo structural changes when subjected to heavy loads or complex working conditions.

[0047] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
