DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figure 1-5, double - door concrete hopper, including an outer frame 1 and a loading frame 2. The loading frame 2 is fixedly connected inside the outer frame 1. Two loading hoppers 3 are fixedly connected to the bottom of the loading frame 2. Four lifting rings 16 are fixedly connected to the upper end of the outer frame 1. Thus, the loading hopper 3 can be lifted to a designated position through the four lifting rings 16. This lifting process is carried out by an external tractor or crane, which is prior art.

[0022] An opening - closing mechanism for double - opening and closing the loading hopper 3 is provided on the loading hopper 3. The opening - closing mechanism includes two arc - shaped shielding plates 6. Two first sector plates 4 and two second sector plates 5 are respectively rotatably connected to the lower sides of the two side walls of the loading hopper 3 through rotating shafts. The lower ends of the two first sector plates 4 are fixedly connected to the upper end of one of the arc - shaped shielding plates 6. The lower ends of the two second sector plates 5 are fixedly connected to the upper end of the other arc - shaped shielding plate 6. A rotating mechanism for driving the two arc - shaped shielding plates 6 to rotate is provided on the outer frame 1.

[0023] The bottom of the loading hopper 3 is arc - shaped, and the bottom of the loading hopper 3 is closely attached to the upper end of the arc - shaped shielding plate 6. The side walls of the first sector plate 4 and the second sector plate 5 are both attached to the side wall of the loading hopper 3.

[0024] Furthermore, as Figure 1 and 2 shown, when the first sector plate 4 and the second sector plate 5 are closely attached to each other, the lower part of the loading hopper 3 can be blocked at this time. When the first sector plate 4 and the second sector plate 5 are separated, the lower part of the loading hopper 3 can be opened at this time, and the materials in the loading hopper 3 can be poured to the required position.

[0025] The rotating mechanism includes a U - shaped plate 7 fixedly connected to the side wall of the outer frame 1. Two fixed blocks 8 are fixedly connected to the side wall of the U - shaped plate 7. Two friction rings 9 are respectively fixedly connected to the upper ends of the two fixed blocks 8. A friction rod 10 is rotatably connected to the common inner wall of the two friction rings 9. First rods 11 and third rods 13 are respectively fixedly connected to the side wall of the friction rod 10 close to the friction ring 9. The side wall of the first rod 11 far from the friction rod 10 is rotatably connected to the side wall of the second rod 12 through a rotating shaft. The side wall of the second rod 12 far from the first rod 11 is rotatably connected to the side wall of the first sector plate 4 through a rotating shaft. The side wall of the third rod 13 far from the friction rod 10 is rotatably connected to the side wall of the fourth rod 14 through a rotating shaft. The side wall of the fourth rod 14 far from the third rod 13 is rotatably connected to the side wall of the second sector plate 5 through a rotating shaft.

[0026] It should be noted that by setting the friction rings 9 and the friction rod 10, the position of the friction rod 10 can be friction - limited to prevent it from rotating automatically at will. When the staff presses down the U - shaped rod 15, as Figure 3As shown, at this time, the first rod 11 moves to the left, and the third rod 13 moves to the right, and then the first rod 11 drives the first fan-shaped plate 4 to rotate to the left through the second rod 12, and the third rod 13 drives the second fan-shaped plate 5 to rotate to the right through the fourth rod 14, thereby opening the bottom of the loading hopper 3, and through the double-door design of the first fan-shaped plate 4 and the second fan-shaped plate 5, the single-door design adopted in the prior art is avoided, so that the weight of the material in the hopper is all concentrated on one surface, which easily leads to damage of the single-door, and the dumping of the material requires the single-door to be rotated at a large angle, and the material cannot be dumped out conveniently and quickly, thereby reducing the working efficiency.

[0027] The side wall of the friction rod 10 is fixedly connected with a C-shaped rod 15 , and the side wall of the C-shaped rod 15 is provided with an anti-skid rubber sleeve.

[0028] When the double-door concrete hopper is in use, the ground staff first moves the concrete and other building materials to the loading frame 2, and then the concrete and other building materials enter the two loading hoppers 3. After the concrete and other building materials are moved, the staff can fix the lifting ropes in the four lifting rings 16 through an external traction machine or a crane, and then the hopper can be lifted to a designated position;

[0029] When it is necessary to pour out the concrete or other building materials in the hopper, the staff can press the U-shaped rod 15 downward, and the friction rod 10 will drive the first rod 11 to move left, and drive the third rod 13 to move right, and then the first rod 11 drives the first fan-shaped plate 4 to rotate left through the second rod 12, and the third rod 13 drives the second fan-shaped plate 5 to rotate right through the fourth rod 14, so that the first fan-shaped plate 4 and the second fan-shaped plate 5 are separated, thereby opening the bottom of the charging hopper 3, and the double-door design of the first fan-shaped plate 4 and the second fan-shaped plate 5 is avoided. The single-door design used in the prior art is avoided, so that the weight of the materials in the hopper is all concentrated on one surface, which is easy to cause damage to the single-door, and the dumping of the materials requires the single-door to be rotated a large angle, and the materials cannot be dumped out conveniently and quickly, thereby reducing the working efficiency.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
