Description

Technical Field

[0001] This invention belongs to the field of coal mining technology, specifically relating to an automatic loading device for coal preparation that can prevent coal blocks from breaking. Background Technology

[0002] Existing coal transport equipment, such as Chinese Patent Application No. CN202111577015.0, discloses a coal transport monitoring method and device. The method includes: determining the real-time coordinate information of the scraper assembly of a scraper conveyor in the coal transport area based on real-time and continuously collected target video data of the coal transport area; inputting the target image data corresponding to the target video data into a large coal identification model, and obtaining the current large coal identification result based on its output; if the result contains large coal, determining whether the large coal is currently located on the scraper conveyor based on the real-time coordinate information of the scraper assembly and the large coal identification result; if so, obtaining the movement state of the large coal to determine whether to issue a transport blockage warning for the large coal. This effectively improves the identification accuracy of large coal, the identification accuracy of the area where large coal is located, and the accuracy of obtaining the movement state of large coal, thereby improving the accuracy of coal transport monitoring and blockage monitoring warnings. However, this patent document does not specify a coal fragment crushing detection scheme.

[0003] Further search revealed that Chinese patent application number CN201921746747.6 discloses a coal block transport device for coal mining. The device includes a base plate, with support legs fixedly connected to the bottom of the base plate, a first buffer pad fixedly connected to the top of the base plate, a second buffer pad fixedly connected to the top of the base plate, a first fixing plate fixedly connected to the inner bottom wall of the base plate, a hydraulic rod fixedly connected to the top of the first fixing plate, a second fixing plate movably connected to the top of the hydraulic rod, and a transport device housing fixedly connected to the top of the second fixing plate. This coal block transport device for coal mining achieves good performance, thus solving the problem of poor performance of general coal block transport devices.

[0004] However, the aforementioned patent documents also fail to address how to prevent crushing during the coal unloading process, as detailed below:

[0005] 1) During the daily unloading of coal, due to the high value of coal, it is necessary to ensure the volume integrity of the coal. This requires more care during unloading to ensure that the coal is not bumped or knocked during loading and unloading. However, the problem is that when the coal is unloaded, it comes into contact with the steel plates of the car body, which can easily cause impact and crushing damage, resulting in various damages to the volume and capacity of the coal, which can easily lead to the overall coal becoming too fine.

[0006] 2) Traditional coal unloading methods generally require manual labor to unload the coal evenly, and unnecessary impacts occur when the coal comes into contact with the truck bed, causing the coal to be crushed. The coal cannot be buffered during unloading to offset the impact caused by contact with the steel plate of the loading and unloading truck bed, which increases the difficulty of automatic loading.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1) The main function of the displacement wheel and gantry crane is to unload the coal. The unloading area is changed by the automatic rotation of the fixed bearing and stepper motor in the middle area of ​​the parallel crossbeam. The unloading is clamped and connected to the square bearing plate by the self-rotating screw, the trapezoidal bracket for unloading and the connecting bracket below. The coal is more evenly dispersed during the unloading stage, and the unloading stage is more convenient and complete. It avoids the coal from being too piled up and crushed at the bottom. It ensures that the coal is not piled up during automatic loading and that the coal is not crushed into pieces.

[0030] 2) Combined with the buffer receiving sleeve, it is used to receive the expanded area. First, it relies on the rolling transmission of the rubber roller to disperse the corresponding placement frame area to achieve expansion. Then, it is transmitted again according to the axial expansion of the rubber roller. Finally, in order to ensure that the transmission stage is more stable, it is transmitted according to the rolling transmission of the rubber roller. In terms of its function, it is to prevent the coal under independent pressure from being too compacted, so that when it is fed, the pressure on the coal is more evenly dispersed by the rubber roller.

[0031] 3) The coal conveying and unloading path is as follows: First, the coal is fed into the side plate through the circular slot, and then rotated by the auger inside the dispersion sleeve when the motor output is energized. At this time, the coal is linearly conveyed and discharged from the slot of the discharge slot. Combined with the distribution of the discharge guide plate, the coal is dispersed and discharged. Moreover, the multiple discharge slots in parallel greatly avoid the situation of uneven coal quality discharge from a single outlet. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1: Please refer to Figure 1 - Figure 3 The present invention provides the following technical solution: an automatic loading device for coal preparation that can prevent coal block breakage, comprising a suspension mechanism 1, an automatic coal block loading and unloading mechanism 2, and a receiving mechanism 5;

[0054] The suspension mechanism 1 is placed on the ground support, and the automatic coal loading and unloading mechanism 2 is installed on top of the suspension mechanism 1;

[0055] The folding mechanism 3 is placed at the bottom of the automatic coal loading and unloading mechanism 2;

[0056] The feature is that the suspension mechanism 1 includes a plurality of displacement wheels 11, a gantry crane 12 is provided at the top center of the plurality of displacement wheels 11, a transverse support 13 is provided at the top of the gantry crane 12, and two parallel crossbars 14 are provided at the top of the transverse support 13.

[0057] A housing 15 is supported at one end of the parallel crossbar 14. A connecting crossbar 16 is laterally connected to the bottom of the housing 15. The two ends of the connecting crossbar 16 are respectively supported by the middle of the designated housing 15.

[0058] An automatic coal loading and unloading mechanism 2 is installed in the middle of the transverse support 13;

[0059] The automatic coal loading and unloading mechanism 2 includes a displacement guide rail 21 set on the surface of two parallel crossbeams 14, and a number of independent track wheels 22 are sequentially arranged on the surface of the displacement guide rail 21.

[0060] A square base plate 23 is provided in the middle of several track wheels 22. Trapezoidal brackets 24 are provided on both sides of the top of the square base plate 23. Trapezoidal block 25 is provided in the middle of the trapezoidal bracket 24. A threaded sleeve 26 for extension and movement is embedded in the middle of the trapezoidal block 25. A self-rotating screw 27 is threaded through the middle of the sleeve 26. Fixed bearings 28 are inserted at both ends of the self-rotating screw 27. The bottom of the two fixed bearings 28 are fixedly set to the middle of the bottom of the displacement guide rail 21 respectively.

[0061] The bottom of the fixed bearing 28 is fixedly installed at the middle of both ends of the displacement guide rail 21. The rear end of the fixed bearing 28 is provided with a stepper motor 29, and the housing end of the stepper motor 29 is fixedly supported by the support end of the fixed bearing 28.

[0062] The output end of the stepper motor 29 passes through the fixed bearing 28 and is connected to the output end of the self-rotating lead screw 27.

[0063] In practical use, the operator first needs to drive the coal-carrying car to the position of the displacement wheel 11 along the ground to achieve forward and backward displacement on the ground. At this time, the operator then rotates the displacement according to the bottom position of the gantry crane 12. In this stage, the gantry crane 12 is supported laterally. During this process, the displacement is pushed through the specific area of ​​the gantry crane 12. During this process, the displacement wheel 11 slides back and forth along the ground according to the position of the displacement wheel 11 until it reaches the bottom of the coal-carrying car.

[0064] The user then supports the material above the specific transport frame 61. At this time, the user needs to open the four doors of the carriage to receive the coal. The placement frame 91, which serves as a buffer, acts as a support point.

[0065] At this point, the personnel again adjust the structure of the hook 93 to attach multiple independent rubber rollers 95, which is used to hook multiple sliding hooks 94 to connect them. This can more effectively complete the state of supporting and bearing the rubber rollers 95, realizing distributed support. When the coal blocks slide down, the back and forth swaying of multiple adjusting hooks 93 and sliding hooks 94 completes the rolling rotation of the rubber rollers 95. After the coal is unloaded, the designated buffer receiving sleeve 96 is used to catch the falling coal to avoid scattering.

[0066] At this stage, the user moves forward and backward along the guide rail extended from the top of the horizontal support 13 and the surface of the parallel crossbar 14. The user then moves forward and backward along the track of the displacement guide rail 21, adapting to the surface of the specific square base plate 23. The specific power source is: the stepper motor 29 is powered on, which drives the fixed bearing 28 to rotate and adjusts the self-rotating lead screw 27 to rotate. The fixed bearing 28 achieves the rotation. At this time, the user moves forward along the track wheel 22 along the trapezoidal support 24. The user then moves forward gradually along the area of ​​the displacement guide rail 21 to the position.

[0079] Material feeding and dispensing:

[0080] The user needs to turn on the drive motor 44 again. After the output shaft rotates, it drives one end of the steering gear 43 to rotate. Finally, the rotation of the auger blade roller embedded in the auger sleeve 41 disperses the coal, avoiding individual material feeding. The coal is discharged through multiple independent discharge slots 48 and one end of the discharge guide plate 49. The discharge guide plate 49 guides the discharge by adjusting the rotation of the movable roller 491.

[0081] During discharge, the operator continuously fine-tunes the dispersing sleeve 47 to achieve forward transmission, and discharges the material through the discharge guide plate 49;

When the coal is discharged, in order to prevent the coal from being damaged and broken due to the weight impact, the rubber rollers 95 are inserted to achieve buffering. After being buffered by multiple rubber rollers 95, the weight is dispersed after being supported by one end of the corresponding placement frame 91. Then the supporting force on the placement frame 91 will be supported by the lifting frame 63 and the wheel 62. In this way, the coal placement stage will not crush the specific structure.

[0083] Surveillance and fine-tuning surveillance as a lens:

[0084] At this time, the user can then view the image of the unloading port after the rotation of the support 73 by coordinating and adjusting the position of the support 73. This image will be transmitted to the surface of the touch panel 83 through video signal feedback, allowing real-time observation of the controlled square support plate 39 and the material discharge port of the conveying auger 492 below.
