[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please see Figure 1 - Figure 5 This application provides a discharge hopper for cement culverts, including a movable hopper base 1 and a discharge hopper body 2 detachably mounted on the hopper base 1. The inner wall of the discharge hopper body 2 is made of a smooth surface and the discharge hopper body 2 is made of a high-strength wear-resistant material. A discharge pipe 3 and a discharge mechanism are provided at the bottom of the discharge hopper body 2. The discharge mechanism includes discharge seats 4 symmetrically mounted on the front and rear sides of the discharge pipe 3, a discharge motor 5 detachably mounted on the upper end of the discharge seats 4, and a discharge mechanism located inside the discharge seats 4. The unloading mechanism also includes a winding assembly that is connected to the unloading motor 5. The unloading motor 5 controls the winding of the winding assembly to control the opening or closing of the discharge port of the discharge pipe 3 by the first unloading plate 6 and the second unloading plate 7, so as to facilitate the unloading by the staff. The unloading mechanism also includes several sets of rotating assemblies respectively set on the left and right sides of the discharge pipe 3, and the first unloading plate 6 and the second unloading plate 7 connected to the rotating assemblies. Both the first unloading plate 6 and the second unloading plate 7 are provided with sealing blocks to block the discharge pipe 3.

[0025] In this utility model, the rotating assembly includes a rotating seat 8 detachably mounted on the discharge pipe 3 and a rotating block 9 rotatably mounted on the rotating seat 8. Several sets of rotating blocks 9 are detachably connected to the first discharge plate 6 and the second discharge plate 7 respectively. When the first discharge plate 6 and the second discharge plate 7 are horizontally attached, they block the discharge pipe 3. Both the first discharge plate 6 and the second discharge plate 7 can rotate from a horizontal state to a vertical state on the discharge pipe 3.

[0026] In this utility model, the winding assembly includes a winding seat 10 disposed inside the unloading seat 4, a winding roller 11 rotatably mounted inside the winding seat 10, and a connecting rope 12 disposed on the winding roller 11. Both sides of the first unloading plate 6 and the second unloading plate 7 are provided with connecting blocks 13 connected to the connecting rope 12. The winding roller 11 can be controlled to rotate the first unloading plate 6 and the second unloading plate 7 respectively through the connecting rope 12.

[0027] In this invention, a first transmission wheel 14, coaxially connected to the take-up roller 11, is rotatably mounted on the outer side of the take-up seat 10. A second transmission wheel 15 is mounted on the output shaft of the unloading motor 5. A transmission belt 16, connected to the first transmission wheel 14, is mounted on the second transmission wheel 15. The unloading motor 5 can control the take-up roller 11 to rotate through the second transmission wheel 15, the transmission belt 16, and the first transmission wheel 14. The two sets of first transmission wheels 14 have different diameters. The diameter of the first transmission wheel 14 that controls the rotation of the second unloading plate 7 through the connecting rope 12 is smaller than the diameter of the first transmission wheel 14 that controls the rotation of the first unloading plate 6. When rotating from a vertical state to a horizontal state, the second unloading plate 7 fits into the discharge pipe 3 faster than the first unloading plate 6. Support plates 26, rotatably connected to the second transmission wheel 15, are provided on both the front and rear sides of the discharge pipe 3. The support plates 26 can prevent the second transmission wheel 15 from being mounted on the discharge pipe 3, thus effectively protecting the discharge pipe 3.

[0028] In this utility model, the unloading seat 4 is provided with several sets of through grooves for the movement of the transmission belt 16 and the connecting rope 12. The inner side of one end of the first unloading plate 6 is provided with a first groove, and the outer side of one end of the second unloading plate 7 is provided with a second groove that fits with the first unloading plate 6. The first unloading plate 6 can support and limit the second unloading plate 7.

[0029] In summary, the unloading hopper body 2 is moved to the unloading point, and the unloading motor 5 is started to rotate forward, driving the second transmission wheel 15 to rotate. The second transmission wheel 15 drives the transmission belt 16 to rotate, the transmission belt 16 drives the first transmission wheel 14 to rotate, and the first transmission wheel 14 drives the take-up roller 11 to rotate, causing the take-up roller 11 to drive the connecting rope 12 to move. The downward movement of the connecting rope 12 causes the connecting block 13 to drive the first unloading plate 6 and the second unloading plate 7 to rotate downward, opening the discharge pipe 3, allowing the unloading hopper body 2 to unload material. After the material is completed, the unloading motor 5 is started to reverse. The second transmission wheel 15, the transmission belt 16 and the first transmission wheel 14 can control the winding roller 11 to rotate. The winding roller 11 drives the first unloading plate 6 and the second unloading plate 7 to rotate upward through the connecting rope 12 and the connecting block 13, so that the rotating block 9 rotates on the rotating seat 8. After the second unloading plate 7 is in contact with the discharge port of the discharge pipe 3, the first unloading plate 6 is connected to the second unloading plate 7, so that the first unloading plate 6 and the second unloading plate 7 block the discharge pipe 3.

A limiting spring 21 is sleeved on the fixing rod 20 and a limiting block 22 connected to the limiting spring 21 is provided. The fixing seat 18 has a moving groove for the limiting block 22 to move inside. The fixing seat 18 has a fixing groove connected to the fixing block 19. The fixing block 19 has a fixing insertion hole connected to the fixing rod 20. The fixing seat 18, the fixing block 19 and the fixing rod 20 are all made of stainless steel.

[0033] In this utility model, the lower end of the hopper seat 1 is detachably equipped with several sets of moving wheels 23, and several sets of reinforcing blocks 24 are symmetrically arranged on the outer surface of the hopper seat 1. A reinforcing rod 25 for limiting the hopper seat 1 is movably installed on the reinforcing block 24. The reinforcing rod 25 and the reinforcing block 24 work together to stably stop the hopper seat 1 on the ground.

[0034] In summary, by connecting the hoisting equipment to the lifting ring, the fixed insert rod 20 is moved outward, which drives the limiting block 22 to move, so that the limiting block 22 squeezes the limiting spring 21, and moves one end of the fixed insert rod 20 out of the fixed insertion hole. The hoisting equipment controls the unloading hopper body 2 to move upward, so that the fixing block 19 is moved out of the fixing groove, and the reinforcement 17 is disassembled and separated from the hopper seat 1.
