[0057] Wherein, hopper discharge assembly includes:

[0058] The lower half of the unloading driving rack 4 is in a cylindrical structure, the upper half of the unloading driving rack 4 is in an incomplete rack structure, the lower end surface of the unloading driving rack 4 is fixedly connected to the upper end surface of the spring supporting block 1, and the cylindrical structure of the lower half of the unloading driving rack 4 is slidably connected to the inner wall of the circular through hole of the spring limiting plate 3.

When the unloading foot pedal 15 is stepped down, the unloading driving rack 4 moves downward, and since the unloading driving rack 4 and the driven gear 5 jointly constitute a gear rack mechanism, the driven gear 5 rotates, which transmits the downward movement of the unloading foot pedal 15 to the rotation of the driven gear 5. At the same time, when the driven gear 5 reversely rotates, i.e. during the process of pulling the carrier hopper 14 back to the transport vehicle after unloading is completed, the unloading driving rack 4 moves upward, and since the upper half of the unloading driving rack 4 is in an incomplete rack structure, the upward movement of the unloading driving rack 4 is limited, thereby enabling the carrier hopper 14 to be smoothly pulled back to the transport vehicle.

In use, the rotation of the driven gear 5 drives the rotation of the unloading driving ratchet wheel 6, and since the unloading driving ratchet wheel 6 and the driven pawl 7 jointly constitute a ratchet mechanism, the unloading driving ratchet wheel 6 only performs transmission in a single rotation direction, which prevents the assembly from being reversely transmitted during the process of automatically rising and resetting the unloading foot pedal 15, and realizes the transmission of the assembly in only one direction.

[0063] The hopper unloading assembly further comprises:

[0064] The first driving bevel gear 8 is eccentrically hingedly connected to the left end surface of the driven pawl 7.

The first driving bevel gear 8 and the first driven bevel gear 9 jointly constitute a bevel gear transmission mechanism, and the transmission ratio of the first driving bevel gear 8 and the first driven bevel gear 9 is 1:2. In use, the rotation of the discharging driving ratchet 6 drives the first driving bevel gear 8 to rotate. Since the first driving bevel gear 8 and the first driven bevel gear 9 jointly constitute a bevel gear transmission mechanism, the first driven bevel gear 9 is driven to rotate. The rotation of the discharging driving ratchet 6 is transmitted to the rotation of the first driven bevel gear 9. At the same time, the transmission ratio of the first driving bevel gear 8 and the first driven bevel gear 9 is 1:2, so that the user can pedal the discharging pedal 15 more easily.

[0066] The hopper discharging assembly further comprises:

[0067] The second driving bevel gear 10 is fixedly connected in concentricity at the front end of the discharging transmission shaft 16.

[0068] The second driven bevel gear 11 is engaged on the right side of the second driving bevel gear 10, and the second driving bevel gear 10 and the second driven bevel gear 11 jointly constitute a bevel gear transmission mechanism. The second driven bevel gear 11 is fixedly connected at the front end of the left end surface of the lower end of the trolley hopper 14. In use, the rotation of the first driven bevel gear 9 drives the second driving bevel gear 10 to rotate. Since the second driving bevel gear 10 and the second driven bevel gear 11 jointly constitute a bevel gear transmission mechanism, the second driven bevel gear 11 is driven to rotate, thereby driving the trolley hopper 14 to perform a dumping action along the rotation axis of the second driven bevel gear 11. After the dumping is completed, the empty trolley hopper 14 is pulled back to the trolley along the rotation axis of the second driven bevel gear 11 by hand.

[0069] The specific use mode and effect of the embodiment one are as follows:

[0070] In use, the unloading pedal 15 is pressed down with the foot and then released, the unloading pedal 15 is lifted back to the original position under the action of the elastic force of the reset spring 2, which enables the unloading pedal 15 to be repeatedly pressed, thereby achieving the reset function of the unloading pedal 15. If it is desired to unload the full construction material carrying vehicle hopper 14, the unloading pedal 15 can be repeatedly pressed to make the carrying vehicle hopper 14 perform a forward tilting action. When the unloading is completed, the empty carrying vehicle hopper 14 is pulled back to the transport vehicle by hand. When the unloading pedal 15 is pressed down, the unloading drive rack 4 moves downward, and since the unloading drive rack 4 and the driven gear 5 jointly constitute a gear and rack mechanism, the driven gear 5 rotates, which transmits the downward movement of the unloading pedal 15 to the rotation of the driven gear 5. At the same time, when the driven gear 5 reversely rotates, i.e. during the process of pulling the carrying vehicle hopper 14 back to the transport vehicle after unloading, the unloading drive rack 4 moves upward. Since the upper half of the unloading drive rack 4 is an incomplete rack structure, the upward movement of the unloading drive rack 4 is limited, thereby enabling the carrying vehicle hopper 14 to be smoothly pulled back to the transport vehicle. The rotation of the driven gear 5 drives the unloading drive ratchet 6 to rotate, and since the unloading drive ratchet 6 and the driven pawl 7 jointly constitute a ratchet mechanism, the unloading drive ratchet 6 only performs single direction transmission, which prevents the reverse transmission of the unloading pedal 15 during the process of automatically rising back to the original position after being pressed down, thereby achieving one-way transmission of the components. The rotation of the unloading drive ratchet 6 drives the first driving bevel gear 8 to rotate, and since the first driving bevel gear 8 and the first driven bevel gear 9 jointly constitute a bevel gear transmission mechanism, the first driven bevel gear 9 rotates, which transmits the rotation of the unloading drive ratchet 6 to the rotation of the first driven bevel gear 9. At the same time, the transmission ratio of the first driving bevel gear 8 and the first driven bevel gear 9 is 1:2, which makes it more labor-saving to press the unloading pedal 15. The rotation of the first driven bevel gear 9 drives the second driving bevel gear 10 to rotate, and since the second driving bevel gear 10 and the second driven bevel gear 11 jointly constitute a bevel gear transmission mechanism, the second driven bevel gear 11 rotates to drive the carrying vehicle hopper 14 to perform a tilting action along the rotation axis of the second driven bevel gear 11. When the unloading is completed, the empty carrying vehicle hopper 14 is pulled back to the transport vehicle along the rotation axis of the second driven bevel gear 11.
