Description

Technical Field

[0001] This application relates to the field of mine conveying devices, and more particularly to an automatic mine conveying device. Background Technology

[0002] When stone quarrying is carried out in a mine, the quarrying equipment places the quarried stone onto a conveying device, which then transports the stone onto a transport vehicle, which then transports the stone out of the mine.

[0003] When the mining equipment dumps the mined stone onto the conveying device, it causes the conveying device to vibrate, which affects the stability of the stone on the conveying device. This can easily cause the stone to shake or even fall off the conveying device, making the stone conveying process less safe. Furthermore, the vibration generated by dumping the stone can easily affect the structural stability of the conveying device, thereby reducing its service life.

[0004] Regarding the aforementioned technologies, the inventors believe that the vibration generated when the mining device dumps the stone onto the conveying device affects the safety of the stone conveying process and reduces the service life of the conveying device. Utility Model Content

[0005] To address the problem that vibrations caused by the dumping of stones onto the conveying device by the mining equipment affect the safety of the stone conveying process and reduce the service life of the conveying device, this application provides an automatic conveying device for mines.

[0006] This application provides an automated conveying device for mines, which adopts the following technical solution:

[0007] An automatic conveying device for mining includes a feeding mechanism, a deceleration mechanism, and a belt conveyor mechanism. The feeding mechanism includes a feeding hopper, a discharge pipe, and a first support rod connected to the feeding hopper. The discharge pipe is connected to the end of the feeding hopper near the belt conveyor mechanism. An installation hole is provided on the side wall of the discharge pipe, and a baffle for changing the diameter of the discharge pipe is provided in the installation hole. The baffle is connected to an electric telescopic rod, which is connected to the first support rod. The deceleration mechanism includes a deceleration tube disposed below the discharge pipe, and the deceleration tube is connected to a second support rod. Multiple deceleration plates are inclinedly disposed inside the deceleration tube. The belt conveyor mechanism is disposed below the deceleration tube.

[0008] By adopting the above technical solution, the mined stone is fed into the hopper. An electric telescopic rod moves a baffle in the mounting hole, adjusting the diameter of the discharge pipe to control the flow rate of the stone. This reduces the vibration caused by directly dumping all the stone onto the belt conveyor. After passing through the discharge pipe, the stone enters the deceleration tube, where an inclined deceleration plate slows down the falling stone, reducing the impact on the belt conveyor. The adjustable discharge pipe and deceleration tube reduce vibration caused by the stone, increasing the safety and stability of the stone transport on the belt conveyor, reducing the impact of vibration, and extending the service life of the belt conveyor.

[0009] Optionally, the belt conveyor mechanism includes a first support column, a drive motor connected to the first support column, a drive wheel rotatably connected to the first support column, a driven wheel rotatably connected to the first support column, and a conveyor belt, wherein the conveyor belt is drivenly connected to the drive wheel and the driven wheel.

[0010] By adopting the above technical solution, the drive motor drives the drive wheel to rotate, the drive wheel drives the conveyor belt to rotate, and the conveyor belt transports the mined stone.

[0011] Optionally, a support platform is provided between the driving wheel and the driven wheel. The support platform is connected to a second support column. A first mounting groove is provided on the support platform. A plurality of support rollers are provided in the first mounting groove. The support rollers are connected to a mounting shaft, and the mounting shaft is connected to the support platform.

[0012] By adopting the above technical solution, the support platform supports the part of the conveyor belt located between the driving wheel and the driven wheel, thereby increasing the structural strength of the belt conveyor mechanism, reducing the possibility of structural damage caused by the impact of falling stones, and reducing the friction force on the conveyor belt, thereby increasing the service life of the conveyor belt.

[0013] Optionally, the mounting shaft is slidably connected to the support platform, a shock-absorbing spring is provided in the first mounting groove, a limiting telescopic rod is provided in the shock-absorbing spring, one end of the shock-absorbing spring is connected to the support platform and the other end is connected to the mounting shaft, one end of the limiting telescopic rod is connected to the support platform and the other end is connected to the mounting shaft.

[0014] By adopting the above technical solution, the shock-absorbing spring and the limiting telescopic rod weaken the vibration of the conveyor belt and the support roller, thereby reducing the impact of vibration on the safety of stone conveying and reducing the impact of vibration on the structural stability of the belt conveyor mechanism.

[0015] Optionally, a baffle plate is provided on the support platform, and the baffle plate is located on both sides of the conveyor belt.

[0016] By adopting the above technical solution, the baffle plate reduces the possibility of stones falling off the conveyor belt due to vibration, thereby increasing the safety of the stone conveying process.

[0017] Optionally, the baffle plate is connected to an inclined pusher plate, the end of the pusher plate near the deceleration tube is connected to the baffle plate, and the end of the pusher plate away from the deceleration tube is inclined toward the center of the conveyor belt.

[0018] By adopting the above technical solution, the pusher plate moves the stones located at the edge of the conveyor belt towards the center of the conveyor belt during the conveyor belt transportation process, thereby further reducing the possibility of the stones falling off the conveyor belt due to vibration, and thus further increasing the safety of stone transportation.

[0019] Optionally, a second mounting groove is provided on the pusher plate, and a pusher roller is provided in the second mounting groove. The pusher roller is rotatably connected to the pusher plate.

[0020] By adopting the above technical solution, the setting of the pusher roller reduces the wear of the pusher plate during the pusher process, thereby increasing the service life of the pusher plate.

[0021] Optionally, a vibration motor is connected to the outer wall of the feed hopper.

[0022] By adopting the above technical solution, the vibrating motor drives the feed hopper to vibrate, thereby reducing the blockage of stones during the process of passing through the discharge pipe and improving the conveying efficiency of stones.

[0023] Optionally, the speed reduction plate is provided with a shock-absorbing pad.

[0024] By adopting the above technical solution, the shock-absorbing pad further reduces the impact force during the stone falling process, thereby further reducing the vibration caused to the belt conveyor mechanism when the stone falls onto the conveyor belt.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The adjustable discharge pipe and the inclined speed reduction plate inside the speed reduction pipe reduce the vibration of the stone on the belt conveyor, thereby increasing the safety and stability of the stone transportation on the belt conveyor and reducing the impact of vibration on the belt conveyor, thus increasing the service life of the belt conveyor.

[0027] 2. The installation of the support platform and support roller increases the structural strength of the belt conveyor mechanism. The installation of the shock-absorbing spring and the limiting telescopic rod reduces the vibration of the conveyor belt and support roller, thereby increasing the safety of the stone conveying process and increasing the service life of the belt conveyor mechanism.

[0028] 3. The installation of baffles and pushers further reduces the possibility of stones falling off the conveyor belt due to vibration during transportation, thereby further increasing the safety of the stone transportation process. Attached Figure Description

The end of the drive pulley 33 away from the drive motor 32 is rotatably connected to the first support column 31 through a bearing. Both ends of the driven pulley 34 are rotatably connected to the first support column 31 through bearings.

[0041] Reference Figure 3 , Figure 4 and Figure 5 A support platform 4 is provided between the driving wheel 33 and the driven wheel 34. The support platform 4 is fixedly connected to a second support column 41. A first mounting groove 42 is provided on the support platform 4.

[0042] A shock-absorbing spring 45 is provided in the first mounting slot 42, and a limiting telescopic rod 46 is provided in the shock-absorbing spring 45. One end of the shock-absorbing spring 45 is fixedly connected to the support platform 4, and the other end is fixedly connected to the mounting shaft 44.

[0045] The implementation principle of an automatic conveying device for mining, as described in this application embodiment, is as follows: Mined stone is placed into the feed hopper 11. An electric telescopic rod 15 moves a baffle 14, which alters the diameter of the discharge pipe 12, thereby regulating the flow of stone. A vibrating motor 16 vibrates the discharge pipe 12 and the feed hopper 11, reducing the likelihood of blockage in the discharge pipe 12. After leaving the discharge pipe 12, the stone enters a deceleration tube 21. An inclined deceleration plate 23 and shock-absorbing pads 24 on the deceleration plate 23 slow down the falling stone. The stone then leaves the deceleration tube 21 and falls onto the conveyor belt 35. As the stone moves along the conveyor belt 35, a pusher plate 48 and a pusher roller 482 push the stone towards the center of the conveyor belt 35. A baffle plate 47 limits the movement of the stone on the conveyor belt 35, reducing the occurrence of stone falling. The support roller 43 on the support platform 4 supports the conveyor belt 35. When the conveyor belt 35 is impacted by stones falling from the deceleration tube 21 and shakes, the shock-absorbing spring 45 and the limiting telescopic rod 46 reduce the shaking of the support roller 43 and the conveyor belt 35, thereby increasing the service life of the belt conveyor mechanism 3.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
