Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mine underground drilling, especially relates to an integrated device for coal mine hydraulic punching height adjustment, weighing and coal unloading. BACKGROUND

[0002] The coal mine hydraulic punching height adjustment, weighing and coal unloading integrated device can improve drilling efficiency, accurately control the amount of punched coal, and effectively screen coal slurry and facilitate transportation in coal screening and transportation, and can reduce costs, enhance equipment flexibility and adaptability, and reduce resource waste and environmental pollution, which is of great significance to efficient, safe, economic and environmentally friendly production of coal mines. The coal mine hydraulic punching height adjustment, weighing and coal unloading integrated device can improve work efficiency, optimize space utilization, enhance equipment collaboration and stability, and reduce equipment management costs and difficulty, so it plays an extremely important role and value in coal mine production operations.

[0003] The coal mine hydraulic punching height adjustment, weighing and coal unloading integrated device generally comprises a punching device, a coal storage device, a weighing device, and a coal unloading device. Coalbed gas extraction is one of the main technical measures for coal mine gas control and coal and gas outburst prevention. With the continuous development of mining activities to the deep part, the permeability of the coal seam will further decrease. In order to improve the extraction efficiency, the coal mine usually uses hydraulic measures to relieve pressure and increase the permeability of the coal seam, so as to achieve the purpose of efficient gas extraction. In the process of using hydraulic punching to increase the permeability of the coal seam, the quality of the drilling is usually judged according to the amount of coal punched out, and the coal slurry punched out can only be transferred to the belt by workers.

[0004] However, the existing part of the coal mine hydraulic punching height adjustment, weighing and coal unloading integrated device cannot avoid manual transfer by workers. Manual transfer of coal by workers is a very heavy physical labor. When coal is transported from the coal storage bin to the transportation equipment, workers need to continuously bend over and exert force, which can easily cause physical fatigue, muscle strain and other occupational injuries after long-term work. This not only affects the health of workers, but also makes workers prone to fatigue operation during work, increasing the risk of mistakes. Therefore, the coal mine hydraulic punching height adjustment, weighing and coal unloading integrated device is proposed to solve the above problems. INVENTION CONTENTS

[0005] In order to make up for the above shortcomings, the coal mine hydraulic punching height adjustment, weighing and coal unloading integrated device is provided to improve the problem that manual transportation cannot be avoided in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The utility model provides an integrated device for coal mine hydraulic flushing height adjustment weighing and coal unloading, which comprises a coal storage bin, a coal inlet is fixedly connected to the top of the coal storage bin, a bin door is rotatably connected to the right side of the coal storage bin, a hydraulic cylinder is fixedly connected to the left side of the coal storage bin, a push partition plate is fixedly connected to the driving end of the hydraulic cylinder, a tight rigid filter plate is slidably connected to the bottom of the push partition plate, a weighing device is fixedly connected to the bottom of the coal storage bin, an automatic telescopic rod device is fixedly connected to the bottom of the weighing device, and a stable platform is fixedly connected to the bottom of the automatic telescopic rod device.

[0008] Further, when the coal mine hydraulic flushing height adjustment weighing and coal unloading integrated device is in operation, coal slurry generated by hydraulic flushing flows into the coal storage bin, and preliminary coal-water separation is realized through the tight rigid filter plate. The weighing device monitors the weight in real time, and the flushing is stopped when the weight reaches the standard. Then, the hydraulic cylinder pushes the push partition plate to move the coal on the filter plate. The automatic telescopic rod device adjusts the height to make the bottom of the coal storage bin level with the belt conveyor and opens the bin door. The coal is pushed to the belt conveyor. The components work cooperatively to form an efficient, orderly, and safe process system, which effectively improves the comprehensive benefits, production continuity, and stability of coal mining.

[0009] As a further description of the above technical solution:

[0010] A guide plate is fixedly connected to the inside of the coal storage bin, and a water outlet is formed in one side of the guide plate.

[0011] Further, in the coal mine hydraulic flushing height adjustment weighing and coal unloading integrated device, after the coal slurry formed by hydraulic flushing enters the coal storage bin, coal-water separation is first realized by the internal fixed tight rigid filter plate. Water penetrates through the filter plate and flows to the guide plate connected to the filter plate. With the water outlet formed in one side of the guide plate and the reasonable slope design of the guide plate, the water is smoothly discharged from the coal storage bin through the water outlet under the action of gravity, which prepares for the subsequent weighing, pushing, and coal unloading processes. The components work cooperatively to orderly promote the entire coal mining operation process, ensuring efficient, stable, and safe completion of coal mining work and improving the comprehensive benefits.

[0012] As a further description of the above technical solution:

[0013] The push partition plate is slidably connected to the inside of the coal storage bin, and the tight rigid filter plate is fixedly connected to the inside of the coal storage bin.

[0014] Further, this allows the push partition plate to smoothly slide along the inside of the coal storage bin after the weighing device reaches the set weight and sends a signal to stop flushing. The push partition plate forcefully and smoothly pushes the coal on the filter plate towards the bin door in cooperation with the tight rigid filter plate. The automatic telescopic rod device adjusts the height and opens the bin door.

[0015] As a further description of the above technical solution:

[0016] The side of the tight rigid filter plate is fixedly connected to the side of the flow guide plate, and the inside of the weighing device is provided with an alarm;

[0017] Further, after the coal slurry generated by the hydraulic punching enters the coal storage bin, the tight rigid filter plate plays a key role, one side of which is fixedly connected to one side of the flow guide plate, and the water in the coal slurry can flow along the flow guide plate connected to the filter plate, and by virtue of the reasonable structural design of the flow guide plate, the water flows to the water outlet along the predetermined route, so that the coal and water are effectively separated, and the weighing device monitors the weight of the whole coal storage bin at any time, and the alarm arranged in the inside of the weighing device will send a signal when the coal quantity reaches the preset standard, so as to trigger the instruction of stopping the hydraulic punching operation.

[0018] The utility model has the advantages of the following beneficial effects:

[0019] 1. In the utility model, when the punching is completed, the coal can be adjusted to the appropriate position by the automatic telescopic rod device and then transported to the belt by the hydraulic cylinder, thereby greatly reducing the labor intensity of workers and realizing the reduction of the risk of manual carrying.

[0020] 2. In the utility model, when the coal slurry enters the coal storage bin, the weighing device can weigh the coal quantity punched out and remind the workers to stop working when the punching reaches the standard, so that the yield is accurately controlled.

[0021] 3. The device is simple to operate, easy to construct and move, and can be repeatedly used, thereby reducing the risk of operation errors. BRIEF DESCRIPTION OF DRAWINGS
