Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a coal loading and transportation device for coal mining. Background Technology

[0002] Coal mining refers to the process of separating valuable coal from underground or the surface and transporting it away from the site. Mining methods are mainly divided into two categories: open-pit mining and underground mining. Open-pit mining is suitable when the coal seam is close to the surface, directly stripping away the surface soil to extract the coal; underground mining is suitable when the coal seam is far from the surface, requiring the excavation of tunnels underground to extract the coal. Mechanized methods are commonly used in the mining process, with hydraulic mining being used in some cases, and underground coal gasification is still in the experimental stage. Coal mining is often accompanied by threats from water, fire, and gas hazards; therefore, coal mining technology has some characteristics that differ from other mineral mining.

[0003] Coal mining requires the use of coal loading and transportation vehicles for transport. However, in the current use of coal loading and transportation vehicles, uneven discharge is prone to occur during the discharge process, resulting in coal residue, which is relatively unsafe and incomplete discharge.

[0004] Therefore, it is necessary to redesign and modify coal loading and transport vehicles to effectively prevent uneven material discharge, coal residue, low safety, and incomplete material discharge that are common problems in the current use of coal loading and transport vehicles during the discharge process. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a coal loading and transportation device that facilitates rapid material discharge. This solves the problems of uneven material discharge, coal residue, low safety, and incomplete material discharge that often occur during the discharge process in current coal loading and transportation vehicles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coal loading and transportation device for coal mining, comprising a coal loading and transportation vehicle, wherein a truck bed is provided on the top of the coal loading and transportation vehicle, a cover plate is movably connected to the right side of the top of the truck bed, a fixing plate is fixedly connected to the top of the truck bed, a transmission assembly is provided on the top of the fixing plate, and positioning assemblies are movably connected to both the front and rear sides of the top of the truck bed.

[0007] In a preferred embodiment of this utility model, the transmission includes a transmission box, which is fixedly connected to the top of a fixed plate. A motor is fixedly installed inside the transmission box, and a worm gear is fixedly connected to the output end of the motor. A bidirectional screw is longitudinally and movably connected to the top of the truck bed. Limiting frames are fixedly connected to both the front and back of the truck bed. The limiting frames are movably connected to the inner side of the bidirectional screw. A threaded sleeve is threaded onto the surface of the bidirectional screw, and a worm wheel that meshes with the worm gear is fixedly connected to the surface of the bidirectional screw.

[0008] In a preferred embodiment of this utility model, the positioning component includes a support rod, which is fixedly connected to the top of the truck bed. A pressure plate is sleeved on the surface of the support rod, and a torsion spring is fixedly connected to the top of the pressure plate. The top of the torsion spring is fixedly connected to the surface of the support rod. The pressure plate is used in conjunction with a cover plate, and the screw sleeve is used in conjunction with the pressure plate.

[0009] As a preferred embodiment of this invention, the surface of the transmission box is provided with heat dissipation vents, and the number of heat dissipation vents is several.

[0010] As a preferred embodiment of this utility model, a positioning rod is fixedly connected to the inner side of the limiting frame, and the positioning rod is slidably connected to the threaded sleeve.

[0011] In a preferred embodiment of this invention, the number of positioning rods is several, and the positioning rods are used in conjunction with the threaded sleeves.

[0012] As a preferred embodiment of this invention, a bracket is fixedly connected to the right side of the transmission box, and the bracket is used in conjunction with the worm gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves transporting coal to a suitable location by a coal loading and transport vehicle. When it is time to unload and discharge the coal, the user starts the motor. The motor's output drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the double-headed screw to rotate, which in turn drives the screw sleeve to rotate. The screw sleeve's rotation causes the pressure plate to press against the coal, causing the pressure plate to flip and release its restraint on the cover plate. This allows the user to easily unload the coal. Afterward, the motor is started in reverse to re-restrain the cover plate, enabling the coal loading and transport vehicle to discharge coal quickly and easily. This replaces existing methods that often result in incomplete discharge, thus achieving a faster and more convenient discharge process.

[0015] 2. This utility model, through the setting of the transmission component, can transmit power to the worm gear, so that the rotation of the worm gear drives the rotation of the worm wheel, thereby causing the bidirectional screw to rotate. It has high safety and is easy for users to use. Attached Figure Description

A worm wheel 57 that meshes with the worm gear 53 is fixedly connected to the surface of the bidirectional screw 54.

[0024] As a technical optimization of this utility model, the transmission component 5 can transmit power to the worm 53, causing the worm 53 to rotate and drive the worm wheel 57 to rotate, thereby causing the bidirectional screw 54 to rotate. This provides high safety and ease of use for users.

[0025] refer to Figure 3 The positioning component 6 includes a support rod 61, which is fixedly connected to the top of the truck bed 2. A pressure plate 62 is sleeved on the surface of the support rod 61. A torsion spring 63 is fixedly connected to the top of the pressure plate 62. The top of the torsion spring 63 is fixedly connected to the surface of the support rod 61. The pressure plate 62 is used in conjunction with the cover plate 3. The screw sleeve 56 is used in conjunction with the pressure plate 62.

[0026] As a technical optimization of this utility model, the positioning component 6 can push and limit the pressure plate 62, which is safer, and can clamp and limit the cover plate 3, which is safer and easier for users to use.

[0027] refer to Figure 4 The surface of the transmission box 51 is provided with heat dissipation vents 7, and the number of heat dissipation vents 7 is several.

[0028] As a technical optimization of this utility model, the heat dissipation vent 7 can dissipate heat from the transmission box 51, effectively improving the safety of the transmission box 51 and making it easier for users to use.

[0029] refer to Figure 3 A positioning rod 8 is fixedly connected to the inner side of the limiting frame 55, and the positioning rod 8 is slidably connected to the screw sleeve 56.

[0031] refer to Figure 3 There are several positioning rods 8, which are used in conjunction with screw sleeves 56.

[0032] As a technical optimization of this utility model, by setting the number of positioning rods 8 to several, multiple positions of the screw sleeve 56 can be positioned, resulting in excellent stability and ease of use for users.

[0033] refer to Figure 4 A bracket 9 is fixedly connected to the right side of the transmission box 51, and the bracket 9 is used in conjunction with the worm gear 53.

[0034] As a technical optimization of this utility model, the bracket 9 can limit the movement of the worm 53, effectively improving the stability of the worm 53 and ensuring its normal rotation.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to transport coal ore, the user loads the coal transport vehicle 1 to a suitable location. When it is time to dump the coal, the user starts the motor 52. The output end of the motor 52 drives the worm gear 53 to rotate. The rotation of the worm gear 53 drives the worm wheel 57 to rotate. The rotation of the worm wheel 57 drives the double-headed screw 54 to rotate. The double-headed screw 54 drives the screw sleeve 56 to rotate. The rotation of the screw sleeve 56 drives the pressing plate 62 to press against it, causing the pressing plate 62 to flip and release the limiting position on the cover plate 3. After that, the user can easily dump the coal. Then, the motor 52 starts in reverse and can limit the cover plate 3 again, thereby achieving the effect of facilitating material discharge.
