Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine excavation, and in particular relates to a buffer material receiving device for coal mine excavation. Background Art

[0002] Currently, when mining coal resources, coal must first be received by receiving equipment and then transported away by conveying equipment. However, in actual operations, most conventional receiving equipment lacks a buffering function. Coal directly falls into the receiving equipment, causing significant impact damage to the receiving equipment. Prolonged use can also cause damage to the receiving equipment, and damage is difficult to replace, requiring improvement. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a buffering material receiving equipment for coal mine excavation, which has excellent buffering function as a whole and is easy to disassemble, assemble and replace, so as to solve the above problems.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a buffering material receiving equipment for coal mine excavation, including a base, a support plate is provided above the base, and the four corners of the bottom of the support plate are connected to the top of the base through a shock absorber assembly, and electric push rods are fixedly mounted on the left and right ends of the bottom of the support plate, and the telescopic ends of the two electric push rods are arranged back to back and fixedly connected to the limit plate, and two plug plates are fixedly provided on the side of the limit plate close to the support plate, and the plug plate on the lower side corresponds to the side of the adjacent support plate and the corresponding support plate side is provided with a first blind groove, and a through groove is provided in the center of the support plate, and a receiving hopper is inserted through the through groove, and the receiving The upper part of the hopper is fixedly sleeved with a mounting plate, which abuts on the top of the support plate, and the plug plate on the upper side corresponds to the side of the adjacent mounting plate and a second blind groove is provided on the side of the corresponding mounting plate, and the limit plate abuts on the support plate and the side of the mounting plate on the same side, and the plug plate is inserted into the corresponding first blind groove and second blind groove, and a receiving trough with a U-shaped longitudinal section is inclined at the bottom of the hopper, and the receiving trough can pass through the through groove and its lower end is open and its higher end is closed and fixedly connected to the outer wall of the hopper through a vertical plate, and the hopper and the receiving trough are both made of foam aluminum and rubber shock-absorbing pads are fixed on the inner walls of both, and wear-resistant ceramic linings are fixed on the rubber shock-absorbing pads.

[0005] Preferably, the through groove is adapted to the receiving hopper.

[0006] Preferably, the mounting plate is adapted to the support plate.

[0007] Preferably, the plug plate is adapted to the corresponding first blind groove and second blind groove.

[0008] Preferably, hydraulic cylinders are vertically fixed at the four corners of the bottom of the base, the piston rods of the hydraulic cylinders face downward and casters are installed on the bottom ends thereof.

[0009] Preferably, an inverted U-shaped support leg made of foam aluminum is fixedly sleeved on the cylinder body of the hydraulic cylinder. When the piston rod of the hydraulic cylinder is in a retracted state, the bottom end of the caster is higher than the bottom end of the support leg.

[0010] The beneficial effect of the utility model is that when receiving materials, the lower end of the receiving trough is aligned with the loading end of the existing conveying equipment, and the material receiving and conveying operations can be carried out. Specifically, the excavated coal and mineral materials first fall into the receiving hopper, and under the guidance of the receiving hopper, the coal and mineral materials continue to fall onto the receiving trough, and then under the guidance of the inclined receiving trough, the coal and mineral materials are unloaded onto the conveying equipment, and are transported to the subsequent process by the conveying equipment.

The receiving hopper and the receiving trough are made of foam aluminum material with high specific stiffness and high damping and shock absorption performance, which itself has excellent shock and impact resistance. In addition, the rubber shock-absorbing pads with excellent damping and shock-absorbing effects and the wear-resistant ceramic linings with wear and impact resistance set on the inner walls of the two can greatly improve the shock absorption, impact resistance and wear resistance of the receiving hopper and the receiving trough themselves, so that the receiving hopper and the receiving trough can receive materials more stably, ensure their own service life, and be more practical.

[0011] When the receiving hopper and receiving trough are damaged and need to be replaced, the electric push rod can be operated in the shutdown state to extend its telescopic end, driving the limit plate away from the support plate and the mounting plate until the plug plate is completely pulled out, thereby releasing the plug-in fixation of the mounting plate. After controlling the receiving hopper and receiving trough to completely move up to above the support plate, the original receiving hopper and receiving trough can be removed as a whole. Then, after taking out the new receiving hopper and receiving trough, first align the receiving hopper and receiving trough with the through slot and plug them into place, so that the mounting plate is in place on the support plate. Then, the electric push rod is operated to retract its telescopic end, driving the limit plate to move until it presses against the corresponding side of the support plate and the mounting plate, so that the plug plate is plugged into the corresponding first blind groove and second blind groove. The mounting plate is plugged and fixed, and the fixed installation of the new receiving hopper and receiving trough is completed. The installation is stable and does not affect subsequent use. In this way, the connecting hopper and receiving trough can be conveniently disassembled and replaced as a whole, making the overall use more flexible and convenient.

DETAILED DESCRIPTION

[0018] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 5 The figure shows a buffered material receiving device for coal mining, comprising a base 1, a support plate 2 disposed above the base 1, and the four corners of the bottom of the support plate 2 connected to the top of the base 1 via shock absorber assemblies 3. Electric push rods 4 are fixedly mounted on the left and right ends of the bottom of the support plate 2. The telescopic ends of the two electric push rods 4 are arranged opposite each other and fixedly connected to a limit plate 5. Two insert plates 6 are fixedly mounted on the side of the limit plate 5 adjacent to the support plate 2, spaced apart vertically. The lower insert plate 6 corresponds to the adjacent side of the support plate 2 and has a first blind groove 7 defined in the corresponding side of the support plate 2. A through groove 8 is defined in the center of the support plate 2, through which a material receiving hopper 9 is inserted. A mounting plate 10 is fixedly mounted on the upper portion of the material receiving hopper 9, which abuts the top of the support plate 2. The upper insert plate 6 corresponds to the adjacent side of the mounting plate 10 and has a second blind groove 11 defined in the corresponding side of the mounting plate 10. The limiting plate 5 abuts against the sides of the support plate 2 and the mounting plate 10 on the same side, and the insert plate 6 is inserted into the corresponding first blind slot 7 and second blind slot 11. A receiving trough 12 with a U-shaped longitudinal section is provided at an angle below the hopper 9. The receiving trough 12 can pass through the through slot 8, with its lower end open and its upper end closed. It is fixedly connected to the outer wall of the hopper 9 via a vertical plate 13. The hopper 9 and the receiving trough 12 are both made of foamed aluminum, and both have rubber shock-absorbing pads 14 fixed to their inner walls. The rubber shock-absorbing pads 14 are fixed to the wear-resistant ceramic linings 15.

[0020] When receiving materials, align the lower end of the receiving trough 12 with the loading end of the existing conveying equipment 19, and then the receiving and conveying operations can be carried out. Specifically, the excavated coal and mineral materials first fall into the receiving hopper 9, and under the guidance of the receiving hopper 9, the coal and mineral materials continue to fall onto the receiving trough 12, and then under the guidance of the inclined receiving trough 12, the coal and mineral materials are unloaded onto the conveying equipment 19, and transported to the subsequent process by the conveying equipment 19. During the process, the arrangement and coordination of the four groups of shock absorber assemblies 3 can form an overall effective buffering and shock absorption for the docking hopper 9 and the receiving trough 12 from the outside. The receiving hopper 9 and the receiving trough 12, which are made of foam aluminum material with high specific stiffness and high damping and shock absorption performance, have excellent shock and impact resistance. In addition, the rubber shock-absorbing pads 14 with excellent damping and shock absorption effects and the wear-resistant ceramic linings 15 with wear resistance and impact resistance set on the inner walls of the two can greatly improve the shock absorption, impact resistance and wear resistance of the receiving hopper 9 and the receiving trough 12, so that the receiving hopper 9 and the receiving trough 12 can receive materials more stably and ensure their own service life, which is more practical. The shock absorber assembly 3 can adopt existing technology, and its specific structure and working principle will not be described in detail here.

[0021] When the receiving hopper 9 and the receiving trough 12 are damaged and need to be replaced, the electric push rod 4 can be operated in the shutdown state to extend its telescopic end, driving the limit plate 5 away from the support plate 2 and the mounting plate 10 until the plug plate 6 is completely pulled out, and the plug-in fixation of the mounting plate 10 can be released. After controlling the receiving hopper 9 and the receiving trough 12 to move completely up to the top of the support plate 2, the original receiving hopper 9 and the receiving trough 12 can be removed as a whole. Next, after taking out the new receiving hopper 9 and receiving trough 12, first align the receiving hopper 9 and the receiving trough 12 with the through slot 8 and plug them into place, so that the mounting plate 10 abuts against the support plate 2, and then operate the electric push rod 4 to shrink its telescopic end, driving the limit plate 5 to move until it presses against the corresponding support plate 2 and the side of the mounting plate 10, so that the plug plate 6 is plugged into the corresponding first blind groove 7 and second blind groove 11, and the mounting plate 10 is plugged and fixed, and the fixed installation of the new receiving hopper 9 and the receiving trough 12 is completed, and the installation is stable and does not affect subsequent use. In this way, the hopper 9 and the receiving trough 12 can be conveniently disassembled and replaced as a whole, and the overall use is more flexible and convenient.

[0022] In this embodiment, the through slot 8 is adapted to the material receiving hopper 9 to ensure that the material receiving hopper 9 is smoothly installed in place.

[0023] In this embodiment, the mounting plate 10 is adapted to the support plate 2 to ensure that the mounting plate 10 is smoothly installed in place.

[0024] In this embodiment, the plug-in board 6 is matched with the corresponding first blind groove 7 and second blind groove 11 to ensure that the plug-in board 6 is smoothly plugged into place.

[0025] In this embodiment, hydraulic cylinders 16 are vertically fixed at the four corners of the bottom of the base 1. The piston rod of the hydraulic cylinder 16 faces downward and casters 17 are installed on its bottom end, so that in actual use, the casters 17 can be used to drive the entire device to move flexibly, which is convenient for adjusting the position of the device according to actual conditions and quickly moving the device to the conveying device 19, making the entire device more convenient and practical.

[0026] In this embodiment, an inverted U-shaped leg 18 made of foamed aluminum is fixedly mounted on the cylinder body of the hydraulic cylinder 16. When the piston rod of the hydraulic cylinder 16 is retracted, the bottom of the caster 17 is higher than the bottom of the leg 18. When the equipment is moved into position, the hydraulic cylinder 16 can be operated to retract its piston rod, driving the caster 17 to be suspended and stored inside the leg 18, and the bottom of the leg 18 is pressed against the ground. The leg 18 can then support and fix the equipment, preventing it from moving freely and facilitating material handling. When the equipment needs to be moved, the hydraulic cylinder 16 can be operated again to extend its piston rod, driving the caster 17 down to the ground and suspending the leg 18, allowing the equipment to be flexibly moved again. In addition, the leg 18 is also made of existing foamed aluminum material, which can provide a certain degree of cushioning and shock absorption for the entire equipment, making the overall operation of the equipment more stable and more practical.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
