A material unloading structure for a rear dump truck compartment comprises: a compartment 1;

[0030] A chute 11, wherein the chute 11 is respectively provided on both sides of the carriage 1, a through groove 12 is provided at one end of the bottom of the inner side of the chute 11, and a limiting groove 13 is provided at the bottom of the through groove 12;

[0031] A driving motor 2, the driving motor 2 is fixedly mounted at both ends of one side of the carriage 1, a screw rod 21 is fixedly mounted on the output end of the driving motor 2, one end of the screw rod 21 is rotatably connected to one end of the inner side of the slide groove 11, a moving block 22 is threadedly connected to the outer side of the screw rod 21, and a scraper 23 is fixedly mounted on one side of the moving block 22;

[0032] A pull rope 3, one end of which is fixedly installed on one end of the moving block 22, the other end of which passes through the inner side of the through groove 12 and extends to the inner side of the limiting groove 13, the other end of which is fixedly installed with a connecting rod 31, the outer side of the connecting rod 31 is provided with a bottom plate 32, a rotating shaft 33 is fixedly installed inside one end of the bottom plate 32, and the two ends of the rotating shaft 33 are rotatably connected to the two sides of the inner side of the carriage 1 respectively.

[0033] A sliding cavity 24 is formed at the bottom of the scraper 23 , spring telescopic rods 25 are fixedly mounted on both ends of the top of the inner side of the sliding cavity 24 , and a moving plate 26 is fixedly mounted on the bottom of the spring telescopic rod 25 .

[0034] Both sides of the scraper 23 are respectively attached to both sides of the inner side surface of the carriage 1 .

[0035] The bottom of the movable plate 26 is attached to the top of the bottom plate 32 .

[0036] The top and bottom of the moving block 22 are respectively fitted with the top and bottom of the inner side of the slide groove 11, so that when in use, the moving block 22 can be limited to prevent the moving block 22 from rotating with the screw rod 21;

[0037] The power supply of the driving motor 2 can be supplied from the vehicle battery;

[0038] The movable plate 26 is pushed by the spring telescopic rod 25 , so that when in use, when the bottom plate 32 is adjusted in angle, the bottom of the movable plate 26 can be attached to the top of the bottom plate 32 , thereby cleaning the materials on the top of the bottom plate 32 .

[0039] The working principle of the unloading structure for a rear dump truck compartment provided by the utility model is as follows:

[0040] When in use, the material is loaded into the interior of the carriage 1 and placed on the top of the bottom plate 32. When unloading is required later, the user can start the drive motor 2 to drive the screw rod 21 to rotate, so that the screw rod 21 is threadedly connected inside the moving block 22, so that the moving block 22 drives the scraper 23 to move toward one end of the carriage 1. When the moving block 22 moves, one end of the pull rope 3 moves together, so that the connecting rod 31 needs to be pulled to move the connecting rod 31 downward, so that the bottom plate 3 is in a state of high front and low back, and at the same time, the scraper 23 can also scrape the material inside the carriage 1. After the unloading contact, the moving block 22 is reset by reversing the drive motor 2, thereby pulling the pull rope 3, so that the bottom plate 32 is in a state of high back and low front.
