[0039] When the loading is completed, the staff drives the synchronous belt 22 to rotate through the adjusting mechanism 5, and the two shielding plates 31 move from the ends of the L-shaped slide rail 13 towards the rectangular loading port 11 under the cooperation of the traction assembly, when the two shielding plates 31 move to the top of the box 1 and contact, at this time, the strip-shaped sealing plates 311 are in close contact with each other, so as to form a complete plane, the pressing mechanism 4 can drive the two L-shaped slide rails 13 to move towards the rectangular loading port 11 through the rotation of the synchronous belt 22, which not only avoids the rigid contact between the shielding plate 31 and the box 1, but also makes the strip-shaped sealing plates 311 more closely contact the rectangular water retaining strip 14 at the top of the box 1, so as to ensure the sealing effect of the box 1.

[0040] It is particularly pointed out that the rectangular loading port 11 in the application can be rectangular or circular, and the corresponding rectangular water retaining strip 14 can be a rectangular water retaining strip or a circular water retaining strip.

[0042] When the locking plate 31 is unlocked, the locking plate 312 is unlocked and the locking plate 313 is unlocked, so that the two locking plates 31 are unlocked and the locking plate 313 is unlocked. The column 3222 contacts the inclined surface of the right-angled trapezoidal block 42 and the isosceles trapezoidal block 43 respectively, so that the corresponding 匚-shaped slide rail 13 moves toward the direction close to the box body 1, so that the strip sealing plate 311 and the rectangular water retaining strip 14 are more closely fitted, thereby improving the sealing effect of the box body 1. When the rectangular loading port 11 needs to be opened, as the two shielding plates 31 move away from each other, the interference column 3222 separates from the right-angled trapezoidal block 42 and the isosceles trapezoidal block 43, and the reset spring Under the action of the elastic force of 124, the 匚-shaped slide rail 13 moves in the direction away from the top of the box body 1. By providing a strip-shaped groove 421, when the connecting plate 312 near the center of the 匚-shaped slide rail 13 moves to the end of the guide bar 41, the resistance column 3222 provided thereon moves into the strip-shaped groove 421 under the action of the elastic force of the resistance spring 323, thereby limiting the moving distance of the baffle plate 31 and preventing the baffle plate 31 from falling off from the box body 1.

[0045] See also Figure 4 and Figure 9 As shown, each strip-shaped sealing plate 311 is provided with strip-shaped sealing gaskets 3112 on both sides along the length direction.

[0046] When the two shielding plates 31 are close to each other, the strip-shaped sealing gaskets 3112 arranged on both sides of the strip-shaped sealing plates 311 are pressed against each other, so that the sealing effect between the strip-shaped sealing plates 311 can be improved, and rainwater can be prevented from entering the box body 1.

[0047] Referring to Figure 3 and Figure 5 , the adjusting mechanism 5 comprises a guide plate 51, a connecting shaft 52, an H-shaped mounting frame 53 and a rotating disc 54. The guide plate 51 is arranged at one end edge of the box body 1 in a horizontal state, and the guide plate 51 is provided with a positioning hole 511. The connecting shaft 52 is arranged in the positioning hole 511 in a vertical state and can rotate. The upper end of the connecting shaft 52 is connected with the rotating shaft 2 at the corresponding position through a first universal coupling 521. The H-shaped mounting frame 53 is arranged on the side of the box body 1 close to the guide plate 51 and below the guide plate 51. The rotating disc 54 is arranged on the top of the H-shaped mounting frame 53 in a vertical state and can rotate. The rotating disc 54 is further provided with a rotating handle 541. The rotating disc 54 and the connecting shaft 52 are connected through a second universal coupling 522.

[0048] The staff rotates the rotating disc 54 through the rotating handle 541. The rotating disc 54 realizes "90-degree" transmission through the first universal coupling 521 and the second universal coupling 522, so that the corresponding rotating shaft 2 rotates. The two rotating shafts 2 are connected through the synchronous belt 22, so that the position of the shielding plate 31 is adjusted. The operation is more simple and convenient. The rotating disc 54 is arranged at a distance of 1.2 m from the bottom of the box body 1, so that the staff can adjust the shielding plate 31 without bending over, which is more labor-saving.
