Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for car tippers, in particular to a high-frequency vibration car cleaning device for car tippers. Background Art

[0002] During the coal mining process, after the coal or gangue transported from underground is turned over by the dumper, the coal or gangue often adheres to the dumper and is difficult to fall off completely.

[0003] Currently, hydraulic or pneumatic car cleaning machines are usually used for cleaning operations;

[0004] Hydraulic car cleaning machines take up a large amount of space and require a dedicated parking lot and workshop. The traditional production process is: after the car tipper turns over the gangue, the car is manually moved under the hydraulic car cleaning machine. The hydraulic car cleaning machine driver operates the equipment and uses the hydraulic bucket to dig out the large pieces of ballast stuck under the car. The hydraulic bucket is then moved to place the ballast on the open space outside the mine car for centralized loading. This results in low cleaning efficiency and high labor costs.

[0005] Among them, the pneumatic car cleaning machine needs to be installed on the rolling ring of the tipping machine. The air source pipeline cannot rotate with the tipping machine, resulting in only 180° rotation for each tipping, which affects the efficiency of the tipping machine. At the same time, the frequent forward and reverse operation of the tipping machine can easily affect the driving mechanism of the tipping machine. In addition, there is a risk of pneumatic pipelines being easily damaged and leaking. Utility Model Content

The high-frequency vibration car cleaning device for the dumper includes two swing arms and two vibration motors, wherein the two vibration motors are respectively close to the two ends of the mine car, and are respectively connected to the corresponding support plates in a hinged manner in the height direction through one of the swing arms, so that when the mine car flips downward to unload, the vibration motor can be attached to the bottom of the mine car due to its own weight, and when the mine car flips upward to reset, the vibration motor can be away from the mine car due to its own weight.

[0008] In a possible implementation, the vibration motor is a DC high-frequency vibration motor, and the vibration motor is connected to a remote controller via remote communication.

[0009] In a possible implementation, a counterweight seat is installed on a side of the vibration motor close to the mining car.

[0010] In a possible implementation, the counterweight seat is a metal seat, and a lead block is embedded in the counterweight seat.

[0011] In a possible implementation, the counterweight seat is connected to a curved plate on a side close to the mine car, and the curved plate matches the surface of the mine car, and the curved plate protrudes from the counterweight seat on the circumference.

[0012] In one possible implementation, the swing arm includes two groups of parallel connecting rod structures, the two groups of parallel connecting rod structures are located at the same height direction and are respectively hinged on both sides of the counterweight seat, each group of parallel connecting rod structures includes two parallel connecting rods distributed in sequence along the vertical direction, and hinge grooves are provided at both ends of the parallel connecting rods.

[0013] Beneficial effects: Compared with the prior art, the high-frequency vibration cleaning device for a car dumper provided by the present application is provided with a vibration motor that can swing up and down at the bottom of the mine car of the car dumper. When the mine car turns downward to unload, the vibration motor swings downward due to its own weight to a position close to the bottom of the mine car to vibrate and unload the materials in the mine car. When the mine car is reset upward to load, the vibration motor moves away from the mine car due to its own weight, without affecting the normal use of the mine car, thereby effectively saving cleaning time, manpower and material resources. One person can complete the car dumping and cleaning. The overall structure is simple, installation and maintenance are convenient, equipment investment costs can be greatly reduced, and space is small.

[0014] The counterweight seat can make the vibration motor more closely attached to the bottom of the mine car, thereby further improving the vibration cleaning effect;

[0015] The arc-shaped plate can further increase the contact area between the counterweight seat and the mine car, and transmit the vibration of the vibration motor to the mine car more comprehensively and quickly, which can further improve the vibration cleaning effect.

[0016] These and other purposes, features and advantages of the present invention are fully reflected in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] refer to Figures 1 to 3An embodiment of the present application provides a high-frequency vibration cleaning device for a car dumper, which is used to be installed on the car dumper, wherein the car dumper includes a frame 10, a mine car 20 and support plates 30 symmetrically arranged on both sides of the mine car 20, wherein the mine car 20 is arranged in the frame 10 in a manner that it can be flipped and unloaded through the support plates 30 on both sides. The high-frequency vibration cleaning device for the dumper includes two swing arms 40 and two vibration motors 50, wherein the two vibration motors 50 are respectively close to the two ends of the mine car 20, and are respectively connected to the corresponding support plate 30 in a hinged manner in the height direction through one of the swing arms 40, that is, each vibration motor 50 is hinged to the outer support plate 30 through the outer swing arm 40, wherein this hinged manner enables the vibration motor 50 to swing up and down in the height direction based on its own weight with the hinge point between the swing arm 40 and the support plate 30 as the rotation axis. In this way, when the mine car 20 is flipped down to unload, the vibration motor 50 will be attached to the bottom of the mine car 20 due to its own weight and vibrate to shake off the material in the mine car 20. At the same time, when the mine car 20 is flipped upward and reset to load, the vibration motor 50 will be away from the mine car 20 due to its own weight, so as not to affect the normal use of the mine car 20.

[0024] Therefore, the high-frequency vibration car cleaning device for the dumper provided in the present application is integrated at the bottom of the mine car 20 and hinged on the back plate 30, which can greatly reduce the occupied space. At the same time, the overall structure is simpler and more compact, which is convenient for installation and subsequent maintenance. It can also effectively reduce equipment costs and streamline manpower and material resources. Only one person is needed to complete the dumping and clearing of the car, and no special cleaning tools, transportation routes and parking lots are required. It is easy to use.

[0025] In one embodiment, the vibration motor 50 is a high-frequency DC vibration motor, and is connected to a remote controller via remote communication. When the mine cart 20 begins unloading, the vibration motor 50 is remotely controlled to vibrate 10 seconds later. The high-frequency vibration generated by the vibration motor 50 is transmitted to the mine cart 20, shaking the material out of the cart 20, making operation convenient and safe. The vibration motor model is HY400DC24.

[0026] In one embodiment, the vibration motor 50 is installed with a counterweight seat 60 on the side close to the mine car 20, so as to increase the weight of the vibration motor 50, so that the vibration motor 50 can be more closely attached to the bottom of the mine car 20, and the vibration is transmitted to the mine car 20 through the counterweight seat 60 to ensure the vibration effect.

[0027] In one embodiment, the counterweight seat 60 is a metal seat, and a lead block is embedded in the counterweight seat 60, so that the weight of the counterweight seat 60 can be increased as much as possible within a limited space.

[0028] In one embodiment, the counterweight seat 60 is connected to a curved plate 61 on the side close to the mine car 20, which cooperates with the surface of the mine car 20. At the same time, the curved plate 61 protrudes from the counterweight seat 60 on the circumferential side, thereby increasing the contact area between the counterweight seat 60 and the mine car 20, so that the counterweight seat 60 is more closely attached to the mine car 20, which can further enhance the vibration effect of the vibration motor 50 on the mine car.

[0029] In one embodiment, the swing arm 40 includes two groups of parallel connecting rod structures 41, wherein the two groups of parallel connecting rod structures 41 are located at the same height direction and are respectively hinged on both sides of the counterweight seat 60. At the same time, each group of parallel connecting rod structures 41 includes two parallel connecting rods 411 distributed in sequence along the vertical direction, and hinge grooves 401 are provided at both ends of the parallel connecting rods 411. Correspondingly, the counterweight seat 60 and the support plate 30 are respectively provided with connecting plates 31 embedded in the hinge grooves 401 and hinged to the parallel connecting rods 411. In this way, a parallelogram structure can be formed by cooperating with the connecting plates 31 on both sides through the two parallel connecting rods 411, so that the vibration motor 50 can be limited at the upper and lower limit positions in the height direction during the up and down swinging process, so that the vibration motor 50 can only swing up and down within a predetermined height travel range, which is safer to use and not easy to damage the vibration motor 50. It can also ensure that the vibration motor 50 can be quickly in place during unloading to ensure work efficiency.

[0030] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
