[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 As shown in Figure 5, this embodiment provides a heavy-duty unloading trolley for a belt conveyor, including a device body 1. The device body 1 is equipped with movable wheels 2. The top of the movable wheels 2 is equipped with a mounting frame 3. The mounting frame 3 is equipped with a trolley head 4 on one side and an unloading carriage 5 on the top of the mounting frame 3. The unloading carriage 5 is equipped with an extension plate 6 on one side. The bottom of the extension plate 6 is equipped with a cylinder 7. The top of the unloading carriage 5 is equipped with a fixed frame 8. Two sets of fixed frames 8 are symmetrically arranged. The inner side of the fixed frame 8 is equipped with a lead screw 81 and a sliding rod 15. The lead screw 81 is connected to a motor 9 and a collar 12 is sleeved on the lead screw 81. One end of the collar 12 is connected to a baffle 13. One end of the baffle 13 is connected to a guide ring 14. The sliding rod 15 is slidably arranged in the guide ring 14. The inner wall of the unloading carriage 5 is equipped with a spring 17. One end of the spring 17 is equipped with an anti-collision buffer plate 18.

[0027] Preferably, the lead screw 81 is threadedly connected to the fixed plate 10, and the fixed plate 10 is fixedly installed below the motor 9. The output shaft of the motor 9 is driven by the lead screw 81, making the movement of the collar 12 and the baffle 13 precise and controllable. The fixed plate 10 enhances the stability of the drive structure, avoids motor 9 shaking under heavy load conditions, and ensures the opening and closing accuracy of the unloading channel. The fixed frame 8 has a first slide groove 11 and a second slide groove 16. The collar 12 is provided inside the first slide groove 11, and the guide ring 14 is slidably installed inside the second slide groove 16. Precise sliding constraints are provided, and with the guiding effect of the slide bar 15, the movement of the baffle 13 is guaranteed to be free from deviation and jamming, improving the smoothness of the opening and closing of the unloading channel and adapting to the needs of rapid unloading of heavy materials. The cylinder body end of the cylinder 7 is hinged to the mounting bracket 3, and the piston rod end of the cylinder 7 is hinged to the extension plate 6, making the tilt angle adjustment of the unloading carriage 5 more flexible and adaptable to different unloading heights or angles. The flexibility of the hinge structure can also buffer the stress when the carriage is tilted and extend the service life of the cylinder 7.

[0028] Preferably, multiple springs 17 are provided and evenly distributed between the anti-collision buffer plate 18 and the unloading carriage 5. The anti-collision buffer plate 18 is made of rubber, which can effectively buffer the impact of heavy materials and prevent the materials from directly hitting the inner wall of the carriage and causing damage. The rubber buffer plate can also reduce the friction between the materials and the carriage, reducing the probability of material residue. The moving wheels 2 are made of heavy-duty wear-resistant tires and are connected to the external drive mechanism, which has a strong load-bearing capacity and is adapted to the weight requirements of heavy materials, ensuring sufficient power for the movement of the trolley and improving the transfer efficiency. The height of the baffle 13 is adapted to the height of the unloading carriage 5, and the length of the baffle 13 is adapted to the width of the unloading carriage 5, preventing materials from spilling during transportation. It can fully open the passage during unloading to ensure the smooth discharge of heavy materials and improve the integrity and efficiency of unloading.

[0029] The working principle and process of this utility model are as follows: In use, the device is moved to the unloading position of the belt conveyor via the movable wheels 2. The motor 9 is started, driving the lead screw 81 to rotate, which in turn moves the fixed plate 10, connecting and fixing the unloading carriage 5 to the belt conveyor. When heavy materials conveyed by the belt conveyor fall into the unloading carriage 5, the anti-collision buffer plate 18, in conjunction with the spring 17, buffers the impact of the materials, preventing damage to the carriage. When the carriage is full, the cylinder 7 is started, and the piston rod pushes the extension plate 6, causing the unloading carriage 5 to tilt. Simultaneously, the motor 9 is started to rotate the lead screw 81 in the opposite direction, causing the baffle 13 to slide along the chute 11 and the slide rod 15, opening the unloading channel and completing the unloading operation of the heavy materials. After unloading, the cylinder resets, causing the carriage to return to its original position, and the baffle slides back to its original position, closing the unloading channel, awaiting the next unloading cycle.
