[0034] like Figure 10-13As shown, two sieve plates 26 are rotatably provided in the material box 20, and two baffles 27 are rotatably provided at the bottom of the material box 20. The ends of the two baffles 27 close to each other have a counterweight portion 271. The baffles 27 and the sieve plates 26 corresponding to the upper and lower parts in the material box 20 are connected through a rack four 201. In this embodiment, gear three 261 is respectively provided at the ends of the two sieve plates 26, and gear four 272 is respectively provided at the ends of the two baffles 27. There are two racks 201 and they are respectively slidably connected to the material box 20. The gear three 261 and gear four 272 corresponding to the upper and lower parts in the material box 20 are respectively meshed with the rack four 201. A matching piece for controlling the rotation of the two sieve plates 26 is rotatably provided on the material box 20. A rack five 202 and a rack six 203 respectively meshed with the two gear three 261 are slidably provided in the material box 20. A rack seven 204 is fixedly provided at one end of the rack six 203. The matching piece includes a gear three 261 and a gear four 272 corresponding to the upper and lower parts in the material box 20. The rotatably connected rod body 28, the gear five 281 and the matching disk 282 coaxially fixed on the rod body 28, the gear five 281 is located between the rack five 202 and the rack seven 204 and meshes with the rack five 202 and the rack seven 204 respectively, the rack five 202 and the rack six 203 are respectively located above the two gear three 261, and the material box 20 is slidably provided with a rod two 29 for locking the matching piece, the rod two 29 is connected to the material box 20 through an elastic member two, the elastic member two is specifically a second spring, and a through hole is opened on the matching disk 282 in a direction parallel to the axis of the rod body 28, and a rod four 283 is slidably provided in the through hole through an elastic member three, the elastic member three is specifically a third spring, and a rod three 121 for unlocking the matching piece is provided on the rack one 12, and when the rod four 283 stops against the rod three 121, the rod four 283 can push the rod two 29 out of the through hole so that the rod two 29 unlocks the matching piece.

[0035] It should be noted that when rod 29 unlocks the mating part, the rod body 28 can rotate freely. At this time, under the action of the two baffles 27's own weight, the two baffles 27 can rotate downward, so that gear four 272 can drive rack four 201 to slide upward, so that gear three 261 drives the sieve plate 26 to rotate downward synchronously, and under the action of rack five 202, rack six 203 and rack seven 204, the two sieve plates 26 can rotate downward synchronously.

[0036] Specific working principle: Reference Figure 1-Figure 13 , stop the vehicle below the conveying end of the conveyor 10, set the rotation direction of the conveyor 10 to be clockwise, and when the material box 20 is conveyed upward at the upper end of the conveyor 10, the rod 113 is inserted into one of the slots 233, so that the top opening of the material box 20 is always facing upward, and the rod 29 is inserted into the through hole, so that the two screen plates 26 are in a horizontally opposite state, and the two baffles 27 are in a horizontally opposite state.

[0037] When the material box 20 is located at the conveying starting end of the conveyor 10, crushed stones are added into the material box 20 from the top opening of the material box 20. Next, in the process of the material box 20 moving upward, when the gear 2 25 meshes with the rack 3 14, the driving member can rotate, so that under the cooperation of the guide groove 241 and the slide bar 152, the material box 20 can reciprocate along the first direction X, so that the smaller particle size part of the crushed stones can pass through the sieve holes on the sieve plate 26 and fall downward into the material cavity formed between the material box 20 and the two sieve plates 26 and the two baffles 27. When the material box 20 moves to the conveying end of the conveyor 10, as the conveyor 10 continues to run, the gear 1 23 begins to mesh with the rack 12, so that the material box 20 rotates counterclockwise around the axis of the shaft 1 21, so that the top opening of the material box 20 is always in a state of facing upwards. When the chain plate corresponding to the material box 20 When the gear 11 moves to a vertical state, the gear 123 is disengaged from the rack 12. In the process from the gear 123 starting to mesh with the rack 12 to the gear 123 being disengaged from the rack 12, the rod 113 is disengaged from the initial slot 123 and is stuck in another slot 123. At this time, the rod 4 283 and the rod 3 121 are stopped, and the rod 4 283 can push the rod 29 out of the through hole so that the rod 29 unlocks the matching parts. At this time, under the action of the gravity of the gravel in the material chamber, the two baffles 27 open downward, and at the same time, the two sieve plates 26 also open downward, so that the gravel with smaller particle size can contact the bottom of the car body first, and then the gravel with larger particle size will fall on the top of the gravel with smaller particle size. The gravel with smaller particle size plays a buffering role on the gravel with larger particle size, and at the same time, it also reduces the impact force of the gravel on the car body, thereby extending the service life of the car body.

[0038] When all the gravel in the material box 20 falls out, as the conveyor 10 continues to run, the material box 20 moves to the lower end of the conveyor 10, and then the gear 1 23 engages with the rack 2 13, so that the rod 1 13 disengages from the other slot 1 233 and gets stuck in the initial slot 1 233. In this process, under the action of the counterweight 271, the two baffles 27 rotate and reset, and at the same time the two screen plates 26 are also reset, and the rod 2 29 enters the through hole again and locks the mating parts. Next, the material box 20 will repeat the above process until the car box is full. It can be understood that when the subsequent material box 20 unloads gravel into the car box, the gravel with smaller particle size in the latter material box 20 will fall into the gap between the gravel with larger particle size unloaded by the previous material box 20 in the car box, thereby improving the utilization rate of the car box space.

[0039] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
