Description

Technical Field

[0001] The utility model relates to the technical field of mine car transportation, in particular to a fixed mine car with convenient unloading. Background Art

[0002] Mine cars are the main equipment for transporting bulk materials such as coal, ore and waste rock in mining operations. At present, mine cars usually use hydraulic cylinders to flip and unload the hopper, but the existing hoppers are usually designed to be open. Once the hopper is flipped, the material in the hopper will be poured out all at once due to the completely open material opening. Although it is helpful to increase the unloading speed, it is difficult to control the unloading amount and it is difficult to unload the materials in batches. When some unloading work needs to be carried out in batches at different locations, the mine car is very troublesome to operate. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Existing hoppers are usually designed to be open. Once the hopper is turned over, the material in the hopper will be poured out all at once due to the completely open material opening. Although this is helpful to increase the unloading speed, it is difficult to control the unloading amount and it is difficult to unload the material in batches. When some unloading work needs to be carried out in batches at different locations, the mine car is very troublesome to operate.

[0025] To solve the above defects in the unloading process of the mine car, please refer to Figure 1-Figure 7The utility model provides a fixed mining car with convenient unloading, which is not only convenient for unloading materials in batches and controlling the unloading amount, but also does not affect the unloading speed when the materials need to be unloaded at one time. The hopper 3 is provided with a driving member 7 for driving the hopper 3 to turn over, and the hopper 3 can be turned over to pour out the materials. A shielding plate 4 is provided at one end of the hopper 3, and the shielding plate 4 is used to block the opening of the hopper 3 and reduce the opening area, which is beneficial to control the amount of materials poured out of the hopper 3. Both sides of the hopper 3 are provided with a slide groove 5 for sliding the shielding plate 4. The slide groove 5 is L-shaped. When batch unloading is required, the shielding plate 4 can slide along the slide groove 5 to the top of the hopper 3 to achieve shielding. When batch unloading is not required, the shielding plate 4 can slide and retract along the slide groove 5 to the end of the hopper 3, which can minimize the space occupied by the shielding plate 4, so that the opening of the hopper 3 is completely open, which can ensure the rate at which the staff can load the hopper 3 and the rate at which the hopper 3 can be unloaded at one time.

[0026] When the material shielding plate 4 is moved to the top of the hopper 3, the material can be easily overfilled. The bevel rack 92 is pressed to slide, and the bevel rack 92 will not affect the stretching of the adjusting plate 8. An elastic member 93 is installed at the other end of the insert block 91, and a fixing block 94 is arranged on the elastic member 93. The fixing block 94 is fixedly installed on the material shielding plate 4. The elastic member 93 includes a sleeve 931, and the sleeve 931 is slidably installed on the material shielding plate 4 left and right, and the sleeve 931 is internally slidably connected with a telescopic rod 932, and the end of the telescopic rod 932 is fixedly connected to the fixing block 94. The outer sleeve of the telescopic rod 932 is provided with a telescopic spring 933, and the two ends of the telescopic spring 933 are fixedly installed on the sleeve 931 and the fixing block 94. The bevel rack 92 abuts against the bevel tooth plate 10 through the elastic force of the telescopic spring 933, so that the adjusting plate 8 can be limited. The opening area of ​​the hopper 3 can be controlled by controlling the pull-out length of the adjusting plate 8. When the adjusting plate 8 is fully unfolded, the hopper can also be closed in cooperation with the material shielding plate 4 to protect the material.

[0027] Due to the action of the bevel rack 92, the adjustment plate 8 cannot slide and reset. In order to facilitate the contraction of the adjustment plate 8, a connecting rod 95 is installed on the outside of the sleeve 931. The ends of the two connecting rods 95 are jointly installed with a mounting seat 96. The mounting seat 96 is installed on the material covering plate 4 for sliding up and down. The mounting seat 96 is pushed upward to drive the two connecting rods 95 to rotate. The connecting rod 95 pushes the insert block 91 to slide through the sleeve 931. The insert block 91 drives the bevel rack 92 to move away from the bevel gear plate 10. At the same time, the sliding adjustment plate 8 can be retracted into the material covering plate 4.

[0028] When the shielding plate 4 slides to the top of the hopper 3, it is necessary to flip the shielding plate 4 to cover the hopper 3. Slide blocks 12 are rotatably installed on both sides of the inner wall of the shielding plate 4. The slide blocks 12 are adapted to the slide groove 5 to facilitate the sliding and flipping of the shielding plate 4.

[0029] When the hopper 3 needs to unload materials at one time, the flipping of the hopper 3 may cause the shielding plate 4 to slide along the slide chute 5. The automatic sliding of the shielding plate 4 may block the staff's line of sight and occupy the unloading space. Therefore, a handle 11 is fixedly installed on the top of the adjusting plate 8, and baffles 6 for limiting the handle 11 are rotatably installed on both sides of the top of the hopper 3. The handle 11 is used to facilitate the extension and retraction of the adjusting plate 8. The baffle 6 is rotated to the top of the handle 11 to prevent the shielding plate 4 from sliding due to its own gravity, thereby ensuring the smooth unloading work.

[0030] In order to realize the automatic overturning of the hopper 3, refer to Figure 1 As shown, the servo motor 71 is fixedly installed on one side of the top of the frame 1, the rotating shaft 72 is fixedly installed on one side of the hopper 3, and the end of the rotating shaft 72 passes through the bracket 2 and is rotatably connected to the bracket 2. The output end of the servo motor 71 and the outside of the rotating shaft 72 are fixedly connected with a pulley 73, and a synchronous belt 74 is installed on the outside of the two pulleys 73. The servo motor 71 can drive the rotating shaft 72 to rotate through the two pulleys 73 and the synchronous belt 74, and then drive the hopper 3 to flip and unload. Compared with the traditional hydraulic cylinder driven flip, the driving member 7 can drive the hopper 3 to achieve a 180-degree flip, which can fully pour out the material and make the unloading more thorough.

[0031] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
