All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a bulk hopper for sand and gravel for a stair climber, including a stair climber body 1. A support 3 is fixedly connected to one end of the base frame of the stair climber body 1. A load-bearing plate 2 is movably connected to the inner wall of the support 3. A movable pin 11 is installed at the other end of the base frame of the stair climber body 1. A positioning plate 8 is provided above the movable pin 11 at the other end of the base frame of the stair climber body 1. A movable plate 6 is movably connected to the top of the positioning plate 8. A flip plate 4 is movably connected to one end of the movable plate 6. Second support side plates 7 are provided on both sides of the movable plate 6 on the base frame of the stair climber body 1. A first support side plate 5 is movably connected to one end of the second support side plate 7. A positioning groove 13 is opened on the inner wall of the second support side plate 7.

[0025] Furthermore, the side view of the bracket 3 is L-shaped, and the front view of the bracket 3 is U-shaped, which facilitates the locking and positioning of the load-bearing plate 2.

[0026] Furthermore, the flap 4 and the movable plate 6 are connected by hinges, and the movable plate 6 and the positioning plate 8 are connected by hinges, which facilitates the folding or unfolding of the movable plate 6 and the positioning plate 8.

[0027] Furthermore, the first support side plate 5 and the second support side plate 7 are connected by a hinge, which facilitates folding or unfolding the first support side plate 5 and the second support side plate 7.

[0028] Furthermore, the outer wall of the base frame of the stair climber body 1 is equipped with a first buckle 9, and the outer walls of the first support side plate 5 and the second support side plate 7 are fixedly connected with a first slot 10 that cooperates with the first buckle 9. There are two sets of the first buckle 9 and the first slot 10, and each set of the first buckle 9 and the first slot 10 is distributed at equal intervals, which facilitates the fixing of the first support side plate 5 and the second support side plate 7.

[0029] Furthermore, the outer wall of the positioning plate 8 is fixedly connected with a pin groove 12 that mates with the movable pin 11, which facilitates the fixing of the positioning plate 8.

[0030] Furthermore, both sides of the movable plate 6 are fixedly connected with positioning pins that cooperate with the positioning groove 13, which facilitates the positioning of the positioning pins through the positioning groove 13, thereby enabling the movable plate 6 to be installed and fixed.

[0031] Furthermore, the outer wall of the first support side plate 5 is fixedly connected with a first positioning block 14 that cooperates with the flip plate 4, which facilitates the fixing of the flip plate 4 and prevents the flip plate 4 from accidentally flipping over during transportation.

[0032] Furthermore, the stair climber body 1 has several second positioning blocks 15 that are equally spaced on both sides, which cooperate with the first support side plate 5 and the second support side plate 7 respectively. This facilitates the positioning of the first support side plate 5 and the second support side plate 7 and prevents the first support side plate 5 and the second support side plate 7 from shifting.

[0033] Furthermore, a second buckle 16 is movably provided at one end of the flip plate 4, and a second slot 17 that cooperates with the second buckle 16 is provided on the top of the load plate 2, which facilitates the positioning of the load plate 2 and makes it easier to open the load plate 2, thereby further improving the convenience of unloading.

[0034] In use, firstly, the first support side plate 5 and the second support side plate 7 are fixed to the base frame of the stair climber body 1 by the first slot 10 and the first buckle 9. Then, the positioning plate 8 is fixed to one end of the base frame of the stair climber body 1 by the pin slot 12 and the movable pin 11. Next, the movable plate 6 is moved perpendicular to the positioning plate 8 by the hinge, and the movable plate 6 drives the positioning pin to insert into the positioning groove 13. Then, the movable plate 6 is pushed to move the positioning pin inside the positioning groove 13 and misalign it with the opening of the positioning groove 13, thereby positioning the movable plate 6. Then, the movable plate 6 is installed between the two second support side plates 7. Then, the flip plate 4, which is parallel to the movable plate 6, is installed between the first support side plates 5, and the movable plate 6 is slid back, so that the movable plate 6 drives the flip plate 4 to slide to the inner wall of the first positioning block 14, thereby passing through the first positioning block. 14. Position the flip plate 4. At this time, the positioning pin is still misaligned with the opening of the positioning groove 13. Then, insert the load plate 2 into the inside of the bracket 3 and connect the second slot 17 at the top of the load plate 2 with the second buckle 16 at one end of the flip plate 4 to fix the load plate 2 and complete the overall assembly work. This effectively improves the convenience of assembly. The sealed space formed after assembly is used to transport sand and gravel to prevent the sand and gravel from spilling during transportation. When transported to the appropriate position, the sliding movable plate 6 drives the flip plate 4 to slide a certain distance, thereby releasing the positioning of the first positioning block 14. Then, the flip plate 4 can be flipped open by the hinge for loading and unloading. At the same time, by opening the connection between the second buckle 16 and the second slot 17, the load plate 2 can be disassembled, thereby further improving the efficiency of unloading.
