[0047] The chassis 409, the connecting column 105 and the second gear 405 are arranged concentrically;

[0048] A fixing plate 106 is also fixedly mounted on the bracket of the conveying device body 101 , and a conveying bucket 107 corresponding to the output end of the conveying device body 101 is fixed on the fixing plate 106 , and the bottom end of the conveying bucket 107 corresponds to the open end of the conveying shell 102 .

[0049] In this embodiment: the coal mine comprehensive mechanized coal mining automatic conveying equipment, when in use, the device is placed at a designated position, and the conveying equipment body 101 is fixedly installed, and the material is stably conveyed by the conveying equipment body 101, when the coal mine material output end is turned and adjusted;

[0050] refer to Figure 6 As shown: by rotating the second screw rod 407, since the second screw rod 407 is threadedly connected with the connecting plate 104, the second screw rod 407 moves upward while rotating, so that the second screw rod 407 is inserted into the corresponding first locking hole 408, thereby locking the second gear 405 at the position of the annular shell 406;

[0051] refer to Figure 5 As shown: by starting the driving motor 203, the first bevel gear 401 is driven to rotate, and since the first bevel gear 401 and the second bevel gear 402 are meshed and connected, the second bevel gear 402 is driven to rotate, and the second bevel gear 402 drives the third gear 403 to rotate through the connecting rod 404, and the third gear 403 is meshed and connected with the second gear 405, and the second gear 405 is in a fixed locking state, so that the third gear 403 can make a circular motion on the surface of the second gear 405, thereby driving the conveying shell 102 and the conveying mechanism 2 to rotate synchronously, and the conveying shell 102 is synchronously turned and adjusted through the support legs 103 and the universal wheels 302, and the universal wheels 302 can move on the ground, and the conveying shell 102 is rotated on the connecting plate 104 through the connecting column 105, and the setting of the connecting column 105 and the connecting plate 104 can provide stable support for the conveying shell 102;

[0052] Through this structure, by introducing an adjustable steering mechanism, the present invention enables the conveying equipment to be adjusted in time according to the needs of different working surfaces, greatly improving the adaptability of the equipment and meeting the transportation needs of complex and changeable coal mine environments. The operator does not need to rotate the conveying equipment as a whole, but can quickly adjust the conveying direction by controlling the steering mechanism, which greatly simplifies the operation process and improves the operation efficiency and convenience. Since the steering mechanism is designed with a high degree of automation, the need for manual adjustment by the operator is reduced, the difficulty and complexity of the operation are reduced, and the labor intensity of the operator is also reduced. By flexibly adjusting the conveying direction, the present invention can effectively reduce the spilling, accumulation or congestion of coal during unloading, ensure that the coal can be smoothly transported, and thus significantly improve the transportation efficiency;

[0053] After the conveying shell 102 is turned to the specified angle, the driving motor 203 is stopped, and then the second screw rod 407 is rotated in the opposite direction, so that one end of the second screw rod 407 is disengaged from the first locking hole 408. As the second screw rod 407 moves downward, one end of the second screw rod 407 is inserted into the second locking hole 410 provided in the chassis 409. Since the second screw rod 407 is connected to the connecting plate 104, and the second screw rod 407 is inserted into the second locking hole 410, the connection and locking of the connecting column 105 and the connecting plate 104 are completed, thereby realizing the position locking of the conveying shell 102, thereby improving the stability of the position of the conveying shell 102 and preventing the movement and dislocation from occurring easily.

[0054] refer to Figure 3 As shown: when the conveying housing 102 turns, the supporting leg 103, the sliding rod 301 and the universal wheel 302 are driven to rotate synchronously. When the ground is uneven, the universal wheel 302 moves and the sliding rod 301 is driven to slide in the supporting leg 103. The sliding rod 301 slides in the limiting groove 304 provided in the supporting leg 103 through the limiting block 303. The limiting block 303 and the limiting groove 304 are provided to limit the sliding rod 301, so that the sliding rod 301 is prevented from being separated from the supporting leg 103.

[0055] When the universal wheel 302 rolls on the uneven ground, the slide bar 301 is flexibly and freely adjusted up and down in the leg 103. At the same time, the slide bar 301 compresses the spring 305, and the slide bar 301 is adaptively adjusted up and down in the leg 103. The leg 103 can be adaptively extended and retracted according to the ups and downs and unevenness of the ground through the self-adaptive adjustment mechanism 3, ensuring that the equipment can remain stable under different terrain conditions. This is particularly important for the complex and changeable working environment of coal mines, avoiding the uneven ground from affecting the steering effect of the conveying shell 102, and further improving the flexibility and practicality of the device.

[0056] After the conveying housing 102 is turned, the first threaded rod 306 can be rotated by setting the first threaded rod 306 so that the first threaded rod 306 moves downward to resist the top of the slide bar 301, so that the slide bar 301 can be limited, thereby improving the support effect of the conveying housing 102;

[0057] The coal and mineral materials are continuously transported by the conveying equipment body 101 and arranged in parallel in the conveying bucket 107, and then fall into the conveying shell 102 through the conveying bucket 107. As the driving motor 203 is started, a set of spiral conveying rods 202 are driven to rotate, and one end of the two sets of spiral conveying rods 202 are fixed with a first gear 201, and the two sets of first gears 201 are meshed and connected, thereby driving the two sets of spiral conveying rods 202 to rotate. As the spiral conveying rods 202 rotate, the coal and mineral materials inside the conveying shell 102 are transported and discharged through the discharge port at one end of the conveying shell 102, thereby completing the transportation of the coal and mineral materials.
