AI Technical Summary
Existing box-type coal mining conveyors cannot achieve automatic unloading, resulting in incomplete unloading and easy residue of coal at the bottom, leading to poor unloading efficiency.
A coal mine transportation and unloading device was designed, including a transfer vehicle, a track, an unloading port, a baffle, a pusher plate, and a drive mechanism. The transfer is achieved by the rolling connection of the track wheels. After the baffle is opened, the coal slides down under the action of gravity, and the pusher plate pushes the attached material. The combination of the movable pusher plate and the baffle structure realizes automatic unloading.
It achieves automated unloading, avoids material residue, and improves the thoroughness of unloading and the practicality of the equipment.

[0021] The utility model discloses an embodiment of a coal mine transportation unloading device, including transfer car 2 and transfer track 1, the bottom of transfer car 2 is installed stable frame 3, and track wheel 4 is installed on stable frame 3, and track wheel 4 is connected with transfer track 1 and rolls, one side of transfer car 2 is provided with unloading port 5, and unloading port 5 bottom is rotatably connected with baffle 7 through hinge 6, and the side close to transfer car 2 of baffle 7 is fixedly connected with sealing plate 8, and sealing plate 8 cooperates with unloading port 5, the side away from unloading port 5 in transfer car 2 is provided with push plate 17, and the other side of transfer car 2 is provided with mounting groove 18, and the both sides of mounting groove 18 are fixedly connected with fixed frame 16, and double -end screw rod 19 is rotatably connected in fixed frame 16, and the both ends of double -end screw rod 19 are threadedly connected with driving cylinder 20, and one end of rotating drive rod 21 is rotatably connected on driving cylinder 20, and the other end of rotating drive rod 21 is rotatably connected on push plate 17, and the driving end of double -end screw rod 19 is fixedly connected with crank handle 22;
[0022] In one case of the embodiment, referring to Figures 1-5 The bottom of baffle 7 is rotatably connected with first rotating plate 13 on the side close to unloading port 5, and second rotating plate 14 is rotatably connected on first rotating plate 13, and first rotating plate 13 and second rotating plate 14 cooperate with the bottom of transfer car 2, and the side edge on the side close to unloading port 5 of baffle 7 is fixedly connected with side guard plate 15, and the utility model first fills the gap between baffle 7 and transfer car 2 by the rotatable connection of first rotating plate 13 and second rotating plate 14, to prevent the material in transfer car 2 from flowing out from the gap between baffle 7 and transfer car 2.
[0023] In one case of the embodiment, referring to Figures 1-5The top of the discharge port 5 is provided with a fixed mounting cylinder 9 fixedly connected to the outer wall of the transfer vehicle 2. The top of the side of the baffle 7 away from the discharge port 5 is fixedly connected with a positioning insert 10. A positioning insert 11 is slidably connected to the positioning insert 10 and the fixed mounting cylinder 9. A handle 12 is fixedly connected to the positioning insert 11. This utility model controls the positioning insert 11 by setting the handle 12. When it is necessary to open the discharge port 5, simply pull the positioning insert 11 out from the positioning insert 10 and the fixed mounting cylinder 9 by using the handle 12 to release the baffle 7 from locking the discharge port 5. Then, when it is necessary to close the discharge port 5, simply close the baffle 7. At this time, the baffle 7 drives the positioning insert 10 to rotate and fit into the fixed mounting cylinder 9. Then, the positioning insert 11 is inserted into the positioning insert 10 and the fixed mounting cylinder 9 again, thereby realizing the installation and fixation of the baffle 7.
[0024] The working principle of this utility model is as follows: Firstly, the transfer car 2 moves freely along the transfer track 1 through the mutual rolling connection between the transfer track 1 and the track wheel 4. The transfer car 2 then transfers the coal. When the coal is transported to the predetermined position, the baffle 7 is opened from the discharge port 5, and the side of the baffle 7 away from the hinge 6 is placed on the transfer equipment. At this time, the coal in the transfer car 2 will slide down the baffle 7 onto the transfer equipment under the action of gravity. During this process, the rotational connection between the first rotating plate 13 and the second rotating plate 14 slides and fills the gap between the baffle 7 and the transfer car 2, thereby preventing the material in the transfer car 2 from flowing out from the gap between the baffle 7 and the transfer car 2. Then, the crank handle 22 can be turned to drive the double-headed screw 19 to rotate. The rotational motion of the double-headed screw 19 is converted into the rotational motion of the drive cylinder 20 through the threaded connection with the drive cylinder 20. The linear motion of the drive cylinder 20 drives the two sets of drive cylinders 20 to move towards each other. The drive cylinder 20 drives the two sets of rotating drive rods 21 to rotate and retract. The rotating drive rods 21 drive the pusher plate 17 to move into the discharge port 5. The pusher plate 17 pushes the coal attached to the inner wall and bottom of the transfer car 2 and discharges the coal along the baffle 7. The present invention controls the positioning rod 11 by setting the handle 12. When it is necessary to open the discharge port 5, the positioning rod 11 can be pulled out from the positioning cylinder 10 and the fixed installation cylinder 9 by using the handle 12 to release the baffle 7 from the lock of the discharge port 5. When it is necessary to close the discharge port 5, the baffle 7 can be closed. At this time, the baffle 7 drives the positioning cylinder 10 to rotate and fit into the fixed installation cylinder 9. Then, the positioning rod 11 is inserted into the positioning cylinder 10 and the fixed installation cylinder 9 to realize the installation and fixation of the baffle 7 again.
[0025] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
