Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation, in particular to a coal loading and transportation device used in coal mining. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. In the process of coal mining, coal transportation equipment is needed to transport coal.

[0003] For example, a Chinese patent with publication number CN219706970U discloses a coal mine transportation device used in coal mine development, which relates to a coal mine transportation device. The utility model includes a transport carriage for transportation, and the transport carriage is provided with an adjustment component and a dustproof component; the adjustment component includes two groups of fixed columns arranged on one side of the transport carriage, and the two groups of fixed columns are symmetrically distributed about the central axis of the transport carriage, and one side of the two groups of fixed columns is provided with a first square through hole, and the other side of the two groups of fixed columns is provided with a plurality of positioning holes, and the plurality of positioning holes are distributed in an array with equal spacing; an adjustment column is provided in the first square through hole, and the adjustment column is provided with a plurality of first circular through holes. The utility model is a coal mine transportation device used in coal mine development, which enables the equipment to adjust its height with the workers, thereby improving the transportation efficiency, while preventing dust from being raised and protecting the health of the workers;

[0004] The height of the wheels in the technical solution recorded in this proposal cannot be adjusted. The road surface of the coal mining site is mostly uneven, and there are many obstacles such as gravel and broken coal on the road. The height of the wheels cannot be adjusted, resulting in a fixed gap between the chassis of the transport car and the ground. When the obstacles on the ground are large, the user needs to constantly adjust the position of the transport car to avoid the obstacles, which is very inconvenient.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a coal loading and transportation device for coal mining is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0038] Embodiment 3 of the utility model of a coal loading and transportation device for coal mining

[0039] Reference Figure 1-Figure 5As shown, dust boxes 1006 are installed on both sides of the interior of the carriage body 1001, and dust collectors 1002 are installed on both sides of the carriage body 1001. The input end of the dust collector 1002 is communicated with the dust box 1006. Connecting plates 1004 are installed on both sides of the bottom end of the cover plate 1003. Bolts 1005 are movably inserted on one side of the upper end of the connecting plate 1004. A fixing plate 1009 is installed on the bottom of the carriage body 1001 near the connecting plate 1004. The bottom end of the bolt 1005 is threadedly connected to the fixing plate 1009. A handle 1007 and a battery pack 1008 are installed on the upper and lower sides of one end of the carriage body 1001 respectively. The battery pack 1008 is communicated with the dust collector 1002 and the servo motor 2007. The electrical connection is made through a conducting wire, and by installing a vacuum cleaner 1002, suction is generated when the vacuum cleaner is working, and the dust generated when the coal is loaded into the carriage body 1001 is sucked away through the dust box 1006. By threading the bolts 1005 and the fixing plate 1009, the carriage body 1001 and the cover 1003 are closed to prevent the coal from falling during transportation. After the bolts 1005 are separated from the fixing plate 1009, the cover 1003 can be opened, and the user can shovel out the coal from the carriage body 1001. By installing a handle 1007, it is convenient to push the carriage body 1001. By installing a battery pack 1008, it is convenient to power the device, and the user can use a controller to control the device.

[0040] Specifically, the working principle of the coal loading and transportation device used in this type of coal mining is as follows: when in use, the user adjusts the height of the carriage body 1001 according to the actual road conditions, and starts the servo motor 2007 through the controller, so that when it works, it drives one of the second bevel gears 2011 to rotate, and the first support seat 2001 and the second support seat 2003 are both rotatably connected with the screw 2009, and the top of the screw 2009 is sleeved with the second bevel gear 2011, and the second bevel gear 2011 is meshed with the first bevel gear 2013 sleeved at both ends of the rotating shaft 2012, and then when the servo motor 2007 is meshed with one of the second bevel gears 2011, the screw 2009 rotatably connected inside the first support seat 2001 and the second support seat 2003 can be made to rotate synchronously, and the screw 2009 and the sleeve 2010 installed on the first adjustment seat 2002 and the second adjustment seat 2004 are threaded. The first adjusting seat 2002 and the second adjusting seat 2004 that are slidably connected are connected, so that they can be raised and lowered. By installing universal wheels 2005 and directional wheels 2006 at the bottom ends of the first adjusting seat 2002 and the second adjusting seat 2004, respectively, the gap between the carriage body 1001 and the ground becomes larger, which makes it convenient for the user to use the universal wheels 2005 and the directional force 2006 to move the carriage body 1001. Finally, the user pours coal into the interior of the carriage body 1001, and starts the vacuum cleaner 1002 through the controller to absorb the dust generated when the coal is poured into the interior of the carriage body 1001. The user uses the handle 1007 to push the carriage body 1001 to move. After moving to the appropriate position, the user separates the bolts 1005 from the fixing plate 1009, and lifts the cover plate 1003, and then the coal inside the carriage body 1001 can be shoveled out.

[0041] It should be noted that in a coal mining and coal loading and transportation device, the specific models and specifications of the battery pack 1008, the vacuum cleaner 1002 and the servo motor 2007 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the field, so it will not be described in detail.

[0042] In a coal loading and transportation device used in coal mining, the power supply and principles of the battery pack 1008, the vacuum cleaner 1002 and the servo motor 2007 are clear to those skilled in the art and will not be described in detail herein.

[0043] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
