[0032] During installation, the first rotating hole 302 is set on the second rotating shaft 105, and the groove 303 and the buckle 103 below the first locking buckle 300 cooperate, so that the first locking buckle 300 can rotate on the hopper body 101.

[0033] like Figure 6 As shown, a second circular hole 401 is provided through the second buckle 400, a U-shaped groove 402 is provided above the second circular hole 401, and a second groove 403 is provided below the second circular hole 401. A stop block 404 is fixedly provided along the vertical direction of the second buckle 400, and the stop block 404 is located on the side of the second buckle 400 away from the second groove 403.

[0034] During installation, the second round hole 401 is fitted onto the first rotating shaft 104, the U-shaped groove 402 and the stop block 404 respectively cooperate with the corresponding parts of the linkage mechanism 200, the groove 403 cooperates with the buckle 103 below the second lock 400, so that the second lock 400 can rotate on the hopper body 101.

[0035] When the linkage mechanism 200 is operated manually, the linkage mechanism 200 transmits power to the first latch 300 and the second latch 400, thereby realizing the opening and closing of the hopper bottom plate 102.

[0036] like Figures 7-11 As shown, the linkage mechanism 200 includes a first circular tube 201, two second circular tubes 202 are provided on one side of the first circular tube 201, the two second circular tubes 202 are symmetrically distributed along the centerline of the axial direction of the first circular tube 201, a third circular tube 203 is provided on the side of the first circular tube 201 away from the second circular tubes 202, and the first circular tube 201 and the second circular tube 202 are connected, the first circular tube 201 and the third circular tube 203 are connected, and the first circular tube 201, the second circular tube 202 and the third circular tube 203 are fixedly connected to the hopper body 101.

[0037] A circular rod 207 is provided inside the first circular tube 201, and an inner tube 204 is provided inside the second circular tube 202. The inner tube 204 is fixedly connected to the hopper body 101. The second circular tube 202 and the inner tube 204 are arranged concentrically. The other side of the inner tube 204 is connected to the inside of the first circular tube 201, and a gap is reserved between the second circular tube 202 and the inner tube 204. The gap is filled with cushioning material. A rectangular groove 209 is provided on the side of the inner tube 204 away from the hopper body 101, and the circular rod 207 slides inside the rectangular groove 209.

[0038] A spring 205 is installed inside the inner tube 204. A connector is fixedly installed on one side of the spring 205. The connector includes a disc 206. One side of the spring 205 is fixedly connected to the hopper body 101, and the other side is connected to the disc 206. The disc 206 and the round rod 207 are fixedly connected.

[0039] The third circular tube 203 is provided with a limiting rod 208 inside. A bushing 211 is fixedly provided on one side along the axial direction of the limiting rod 208. A limiting groove 210 is opened on the side of the limiting rod 208 away from the bushing 211. The bushing 211 is rotatably mounted on the circular rod 207.

[0040] During operation, when the limit rod 208 is manually pushed or pulled, the round rod 207 slides inside the rectangular groove 209, while the disc 206 drives the spring 205 to compress or stretch. The rectangular groove 209 ensures the stability and accuracy of the round rod 207 during movement, preventing excessive movement or deviation.

[0041] During installation, the first circular tube 201 and the second through hole 107 are set at the same center, the third circular tube 203 and the first through hole 106 are set at the same center, the circular rod 207 is set on the first circular hole 301, and the limiting rod 208 is set on the U-shaped groove 402.

[0042] The linkage mechanism 200 drives multiple first latches 300 to rotate synchronously, so that the bottom plate 102 of the hopper remains stable during opening or closing, avoiding jamming or damage caused by uneven force on one side, and enhancing the stability and durability of the equipment.

[0043] The second latch 400 provides an additional fixing point for the hopper 100. Through the cooperation of the limiting rod 208 and the U-shaped groove 402, as well as the cooperation of the groove 403 and the corresponding component, the second latch 400 is prevented from shifting laterally during transportation, further ensuring the safety of the hopper 100 during the transfer process and preventing the risk of the hopper bottom plate 102 accidentally falling off.

[0044] The working principle of this utility model: When earthwork needs to be transported, the earthwork is first loaded into the silo 100. The silo body 101 and the silo bottom plate 102 of the silo 100 form a closed storage space that can hold a large amount of earthwork. During the loading process, the first stiffening rib 109 and the second stiffening rib 108 enhance the strength of the silo body 101 to prevent deformation during earthwork loading.

[0045] After loading is completed, the silo 100 is lifted to the preset position using a hoisting mechanism. During the lifting process, the four lifting rings on the silo body 101 ensure its stability and prevent soil spillage due to shaking. When the silo 100 is lifted to a certain height above the ground, the operator begins to operate the linkage mechanism 200.

[0046] The operator lifts the limiting rod 208 upwards, removing it from the U-shaped groove 402. Then, the operator manually rotates the second latch 400, which rotates on the first rotating shaft 104 through the second round hole 401. The groove 403 separates from the buckle 103. After the second latch 400 rotates 90°, the operator pulls the limiting rod 208, engaging the stop block 404 and the rectangular groove 209 on the second latch 400, thus limiting the limiting rod 208 to return to its original position when the spring 205 returns to its original state.

[0047] Simultaneously, during the pulling of the limiting rod 208, the limiting rod 208, under the action of the bushing 211, drives the round rod 207 to slide within the rectangular groove 209. As the round rod 207 slides, it stretches the spring 205 via the disc 206. At the same time, the round rod 207 rotates within the first circular hole 301, transmitting power to the first latch 300.

[0048] After receiving power, the first latch 300 begins to rotate. The first latch 300 rotates on the second rotating shaft 105 through the first rotating hole 302, and the groove 303 separates from the buckle 103.

[0049] As the first latch 300 and the second latch 400 rotate, the bottom plate 102 of the hopper rotates around the rotating mechanism under the action of the first hinge plate 110 and the second hinge plate 111, and the bottom of the hopper 100 gradually opens, allowing the excavated soil to be smoothly unloaded under the action of gravity.

[0050] After the earthwork is unloaded, the operator pushes the bottom plate 102 of the silo back to its original position, then pulls the limit rod 208 and rotates the second lock 400. The groove 403 of the second lock 400 re-engages with the buckle 103, so that the second lock 400 also returns to its initial locked state.

[0051] At the same time, the operator puts the limiting rod 208 back into the U-shaped groove 402. At this time, the stop block 404 no longer restricts the limiting rod 208, the spring 205 returns to its original state, and the disc 206 drives the round rod 207 to slide in the reverse direction in the rectangular groove 209. When the round rod 207 slides in the reverse direction, it drives the first latch 300 to rotate in the reverse direction. The groove 303 re-engages with the buckle 103, so that the first latch 300 returns to the initial locked state.

[0052] The hopper 100 re-forms a closed storage space for the next loading and transfer of earthwork. This design allows the earthwork transfer hopper to quickly return to a loading state after unloading, greatly improving construction efficiency and reducing the time and difficulty of manual operation. At the same time, its simple structure and strong adaptability allow for flexible use in various constrained scenarios, reducing construction costs and improving construction safety and reliability.
