Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figures 1-4 In this embodiment of the present invention, an anti-clogging concrete feeding hopper includes a base 1, a mixing hopper 2 fixedly connected to the base 1, a bottom inclined groove 3 at the bottom of the mixing hopper 2, a discharge port 4 at the lowest point of the bottom inclined groove 3, a feeding hopper 8 on one side of the mixing hopper 2, a feeding port 9 at the top of the mixing hopper 2, a discharge end of the feeding hopper 8 rotatably connected to the feeding port 9, a filling port 10 at the other end of the feeding hopper 8, a first mixing shaft 18 rotatably connected to the front end of the feeding hopper 8, a second mixing shaft 19 rotatably connected to the rear end of the feeding hopper 8, a universal coupling 20 installed between the first mixing shaft 18 and the second mixing shaft 19, a second motor 21 fixedly connected to the outer wall of the feeding hopper 8, and the output shaft of the second motor 21 fixedly connected to the second mixing shaft 19; a mixing assembly is installed inside the mixing hopper 2; a hoisting assembly is installed on the base 1; and a box cover assembly is installed inside the filling port 10.
[0023] This invention first injects multiple sets of raw materials into the feeding hopper 8 through the feeding port 10. After feeding, the feeding port 10 is sealed by the box cover assembly. Then, the feeding hopper 8 is rotated and lifted by the hoisting assembly. At this time, the feeding hopper 8 rotates and rises around the feeding port 9. When the feeding hopper 8 is lifted, the raw materials in the feeding hopper 8 slide into the mixing hopper 2 under the action of gravity. As the raw materials fall, the second motor 21 drives the second mixing shaft 19 to rotate. At the same time, the universal coupling 20 drives the first mixing shaft 18 to rotate. At this time, the first mixing shaft 18 and the second mixing shaft 19 rotate synchronously, thereby stirring the raw materials in the feeding hopper 8 and preventing the raw materials in the feeding hopper 8 from clumping and causing blockage. Then, the mixing assembly stirs and premixes the raw materials added to the mixing hopper 2.
[0024] In one instance of this embodiment, please refer to Figures 1-4 The stirring assembly includes a mounting frame 5 fixedly connected inside the stirring hopper 2. A first motor 6 is fixedly connected to the mounting frame 5. A stirring rod 7 is fixedly connected to the output shaft of the first motor 6. The stirring rod 7 is disposed inside the stirring hopper 2. The stirring assembly drives the stirring rod 7 to rotate through the first motor 6, thereby stirring the raw materials in the stirring hopper 2 through the stirring rod 7.
[0025] In one instance of this embodiment, please refer to Figures 1-4 The hoisting assembly includes a fixed frame 23 fixedly connected to the base 1, a rotating shaft 24 rotatably connected inside the fixed frame, a winding drum 25 fixedly connected to the rotating shaft 24, one end of a steel cable wound on the winding drum 25, traction shafts 22 fixedly connected to both sides of the feeding hopper 8, the other end of the steel cable fixedly connected to the traction shaft 22, a third motor 26 fixedly connected to the fixed frame 23, and the output shaft of the third motor 26 fixedly connected to the rotating shaft 24;
[0026] The hoisting assembly drives the rotating shaft 24 to rotate via the third motor 26. The rotating shaft 24 drives the two sets of winding drums 25 to rotate, thereby winding or unwinding the steel cable via the winding drums 25. The steel cable drives the feeding hopper 8 to rotate and rise around the feeding port 9 via the traction shaft 22.
[0027] In one instance of this embodiment, please refer to Figures 1-4 The box cover assembly includes a cover plate 11 rotatably connected to the filling port 10, a mounting hole 12 fixedly connected to the cover plate 11, a mounting base 13 fixedly connected to the feeding hopper 8, a sliding telescopic rod 14 slidably connected inside the mounting base 13, a pin 16 fixedly connected to one end of the sliding telescopic rod 14, a pull ring 15 fixedly connected to the other end of the sliding telescopic rod 14, the pin 16 slidably connected to the mounting hole 12, and a spring 17 sleeved on the sliding telescopic rod 14 is provided between the mounting base 13 and the pin 16.
[0028] The cover assembly closes the filling port 10 with the cover plate 11 and slides the pin 16 through the mounting base 13 and the sliding telescopic rod 14. The pin 16 is pushed by the spring 17 and inserted into the mounting hole 12. The cooperation between the pin 16 and the mounting hole 12 fixes the cover plate 11 and the feeding hopper 8, thus fixing the cover plate 11 into the filling port 10. When the cover plate 11 needs to be opened, simply pull the pull ring 15 to pull the pin 16 out of the mounting hole 12, which releases the pin 16 from the relative fixation of the cover plate 11, allowing the cover plate 11 to be opened.
