[0030] The specific usage and function of this embodiment are as follows: fix the positioning guide frame 1 at a suitable position of the foundation pit, and then transfer the earth to the conveying hopper 4. At this time, the positioning electromagnet 402 is energized to generate magnetic force to attract the positioning metal block 602, so that the positioning metal block 602 drives the limiting mounting baffle 601 and the sealing baffle 6 to slide along the guide mounting plate 5, so that the sealing baffle 6 is blocked above the conveying hopper 4. When the motor reels in the traction rope, the traction rope pulls the conveying hopper 4 and the positioning mounting frame 3 to slide along the positioning guide groove 2. After the conveying hopper 4 moves to the destination, the positioning electromagnet 402 is de-energized, and the second reset elastic member 603 pushes the sealing baffle 6 to reset, so that the conveying hopper 4 is opened, which is convenient for taking out the earth.

[0031] Embodiment 2:

[0032] As attached Figure 2 To Attachment Figure 6 As shown:

[0033] On the basis of the first embodiment, it further includes a blocking structure and a limiting blocking rod 7 ; the blocking structure is arranged at the lower part of the positioning guide frame 1 ; the limiting blocking rod 7 is rotatably connected to the lower part of the positioning guide frame 1 .

[0034] The blocking structure includes a positioning connection shaft 101 and a limit transmission gear 102 ; the positioning connection shaft 101 is rotatably connected to the lower part of the positioning guide frame 1 ; and the limit transmission gear 102 is fixedly connected to the middle part of the positioning connection shaft 101 .

[0035] Among them, the blocking structure also includes a limited transmission rack 103 and a first reset elastic member 104; the limited transmission rack 103 is slidably connected to the lower part of the positioning guide frame 1, and the limited transmission rack 103 is meshed with the limited transmission gear 102; the limited transmission rack 103 is elastically connected to the positioning guide frame 1 through the first reset elastic member 104.

[0036] Among them, the blocking structure also includes a rubber dust cover 105 and a limiting pressure plate 401; the lower part of the rubber dust cover 105 is fixedly connected to the lower part of the positioning guide frame 1, and the upper part of the rubber dust cover 105 is fixedly connected to the upper part of the limiting transmission rack 103; the limiting pressure plate 401 is fixedly connected to the lower part of the conveying hopper 4.

[0038] The specific usage and function of this embodiment: during the movement of the conveying hopper 4, the guide roller 301 will roll in the positioning guide groove 2. When the conveying hopper 4 moves from a high position to a low position, the limit pressing plate 401 will contact the rubber dust cover 105 and gradually press the rubber dust cover 105 and the limit transmission rack 103 downward, so that the limit transmission rack 103 pushes the limit transmission gear 102 and the positioning connecting shaft 101 to rotate. When the positioning connecting shaft 101 rotates, it will drive the limit stop rod 7 to rotate, so that the limit stop rod 7 is retracted. At this time, the construction Personnel can approach the conveyor to conveniently transfer earthwork to the conveying hopper 4. When the conveying hopper 4 moves from a low place to a high place, the pressure on the limit transmission rack 103 gradually decreases, and the first reset elastic member 104 will push the limit transmission rack 103 to reset, so that the limit transmission gear 102 reverses. At this time, the limit stop rod 7 will be unfolded, so that construction personnel cannot approach the conveyor. The reset volute spring 701 and the first reset elastic member 104 can limit the position of the limit stop rod 7 to prevent the limit stop rod 7 from being retracted under the action of its own gravity.
