[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-6 This utility model provides an embodiment of a bulk aggregate discharge device, comprising a carriage 1 and a bulk discharge pipe 2. The bulk discharge pipe 2 is provided on the outside of the carriage 1. A conveying pipe 3 is slidably fitted inside the bulk discharge pipe 2, extending to the outside of the bulk discharge pipe 2. A fixed dust cover 4 is fitted on the surface of the bulk discharge pipe 2. Sliding dust covers 5 are symmetrically arranged on the outside of the fixed dust cover 4. Multiple sets of flexible dust curtains 6 with equal spacing are installed on the side walls of the sliding dust covers 5. The upper part of the fixed dust cover 4... A servo motor 7 is installed on the side wall of the bulk material feeding pipe 2. A threaded rod 8 is installed at the output end of the servo motor 7. A threaded sleeve 9 is installed on the side wall of the conveying pipe 3. The threaded rod 8 extends through the threaded sleeve 9 to its outside. The threaded rod 8 is threadedly connected to the threaded sleeve 9. A second cylinder 19 is installed on the surface of the bulk material feeding pipe 2 below the fixed dust cover 4. A second push rod 20 is installed at the output end of the second cylinder 19. A movable limit plate 21 is installed at the bottom end of the second push rod 20. The movable limit plate 21 is slidably connected to the bulk material feeding pipe 2.

[0026] A fixed limiting plate 22 is installed at the bottom end of the bulk material feeding pipe 2, and a material level sensor 23 is installed on the side wall of the fixed limiting plate 22.

[0027] When using the bulk aggregate discharge device, the vehicle loading channel has fixed inlet and outlet. When the front end of the truck bed 1 reaches directly below the bulk discharge pipe 2, the servo motor 7 is activated. Supported by the bulk discharge pipe 2, the servo motor 7 drives the threaded rod 8 to rotate. With the threaded connection between the threaded rod 8 and the threaded sleeve 9, the threaded rod 8 moves up and down on the surface of the threaded sleeve 9. The threaded rod 8 drives the servo motor 7 and the bulk discharge pipe 2 to move up and down. The bulk discharge pipe 2 drives the fixed dust cover 4, the sliding dust cover 5, and the flexible dust curtain 6 to move up and down to a suitable height. The bulk discharge pipe 2 then begins to discharge material. When the material accumulation height reaches the bottom of the fixed limit plate 22, it will touch the material level sensor 23. The material level sensor 23 transmits the signal to the external controller for operator monitoring. The operator prompts the driver to move the truck forward. During the movement, vehicle deviation is inevitable. When material naturally accumulates on both sides, The height of the side panel of the carriage 1 is inconsistent with the height of the side panel. When the second cylinder 19 is opened, the second cylinder 19 drives the second push rod 20 to move up and down under the support of the bulk material discharge pipe 2. The second push rod 20 drives the moving limit plate 21 to move up and down, so that the height of the moving limit plate 21 can be adjusted in time for material discharge, avoiding the phenomenon of more material on one side and less material on the other. When the height of the moving limit plate 21 is lower than the fixed limit plate 22, more material will be discharged on the side of the fixed limit plate 22, and vice versa. When the loading is completed, the servo motor 7 is opened in the opposite direction, so that the bulk material discharge pipe 2, the fixed dust cover 4, the sliding dust cover 5, and the flexible dust curtain 6 move upward to the top of the carriage 1, and drive the car away. This realizes the convenient lifting and lowering of the material discharge pipe height of the bulk material discharge device to control the material feeding and discharging, effectively controls the loading material level, avoids the phenomenon of incomplete loading or overflow due to improper control, and improves the material discharge efficiency of the bulk material discharge device.

[0031] The first push rod 14 is movably connected to the support shaft 15, and guide rails 17 are installed on both sides of the fixed dust cover 4.

[0032] Two sets of sliders 18 are symmetrically installed on the inner wall of the sliding dust cover 5, and the sliders 18 are slidably connected to the guide rail 17.

[0033] When dust protection is required for carriages 1 of different widths, the two sets of first cylinders 13 are opened. Under the movable support of the support block 12, the first cylinders 13 drive the first push rod 14 to move. The first push rod 14 drives the support shaft 15 to move. With the sliding connection of the guide rail 17 and the slider 18, the support shaft 15 drives the support seat 16, the sliding dust cover 5, and the flexible dust curtain 6 to move to the designated position. The carriage 1 is protected by multiple sets of flexible dust curtains 6. According to the material accumulation angle and accumulation shape, the flexible dust curtains 6 achieve the best sealing state with the side baffles and material surface of the carriage 1. This realizes the convenient dust blocking of the bulk material discharge device, avoids the obstruction of vision due to excessive dust, and improves the safety of the bulk material discharge device.

[0034] Working principle: Servo motor 7 drives threaded rod 8 to rotate, and threaded rod 8 moves up and down on the surface of threaded sleeve 9. Threaded rod 8 drives servo motor 7 and bulk material discharge pipe 2 to move up and down. Bulk material discharge pipe 2 drives fixed dust cover 4, sliding dust cover 5, and flexible dust curtain 6 to move up and down to a suitable height, and material discharge begins. When the material accumulation height reaches the bottom of fixed limit plate 22, it will touch material level sensor 23. Material level sensor 23 transmits the signal to external controller for operator monitoring. The operator presses the forward movement button, and the prompt signal is displayed on the LED screen and voice prompts the driver to move the vehicle forward. During the vehicle movement process, vehicle deviation is inevitable. When it is found that the natural accumulation height of material on both sides is inconsistent with the relative height of the side plate of the carriage 1, the second cylinder 19 drives the second push rod 20 to... The second push rod 20 moves up and down, driving the moving limit plate 21 to move up and down, so that the height of the moving limit plate 21 can be adjusted in time for material release, avoiding the phenomenon of more or less on one side. When the loading is completed, the servo motor 7 is turned on in reverse, so that the bulk material discharge pipe 2, fixed dust cover 4, sliding dust cover 5, and flexible dust curtain 6 move upward to the top of the car body 1, and drive the car away. The first cylinder 13 drives the first push rod 14 to move, the first push rod 14 drives the support shaft 15 to move, and the support shaft 15 drives the support seat 16, sliding dust cover 5, and flexible dust curtain 6 to move to the designated position.
