[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a dump semi-trailer that can avoid unloading residues includes a frame 1. The middle part of the frame 1 is connected to the car body 4 through multiple hydraulic rods 2. The lower right part of the car body 4 is rotatably connected to the upper right part of the frame 1. The lower part of the car body 4 is connected to the car body 4 through a limiting mechanism 3.

[0021] In this embodiment, the limiting mechanism 3 includes a support rod 301, a pulley 302, a slide groove 303, a rack 304, a shaft rod 305, a tooth block 306 and a connecting groove 307. The lower end of the support rod 301 is rotatably connected to the upper right side of the frame 1, the middle part of the shaft rod 305 is fixedly connected to the upper end of the support rod 301, the middle part of the pulley 302 is rotatably connected to the side of the shaft rod 305 close to the support rod 301, and one end of the tooth block 306 is rotatably connected to the front and rear ends of the shaft rod 305 through a torsion spring. The connecting groove 307 is opened in the middle of the slide 303, the shaft 305 is externally slidably connected to the inside of the connecting groove 307, the upper part of the slide 303 is installed on the front and rear sides of the carriage 4, the outer periphery of the pulley 302 is slidably connected to the inside of the slide 303, one side of the rack 304 is fixedly connected to the upper part of the separated side of the slide 303, an electromagnet 309 is provided at the lower part of the tooth block 306, and an iron bar 308 is provided at the lower part of the separated side of the slide 303, and one end of the tooth block 306 is engaged with the rack 304.

[0022] Specifically, during the lifting process of the car 4, the support rod 301 pulls the pulley 302 to slide inside the slide groove 303, so that the tooth block 306 slides under the rack 304. When the car 4 stops lifting, the torsion spring will cause the tooth block 306 to engage with the rack 304, so that the support rod 301 supports the car 4 to prevent the car 4 from falling. When the car 4 needs to be lowered, the electromagnet 309 is energized, so that the electromagnet 309 drives the tooth block 306 to overcome the elastic force of the torsion spring and approach the iron bar 308, so that the tooth block 306 cannot engage with the rack 304, thereby allowing the car 4 to be lowered.

[0023] In this embodiment, the plurality of hydraulic rods 2 are parallel to each other, and at least two hydraulic rods 2 are provided. A foot support 6 is provided at the lower left side of the carriage 4 , and a vibration motor 5 is provided at the left side of the carriage 4 .

[0024] Specifically, the carriage 4 can be stably lifted by a plurality of parallel hydraulic rods 2. When the carriage 4 is tilted, the vibration motor 5 is driven to make the carriage 4 vibrate, so that the material inside the carriage 4 is emptied.

[0025] Working principle:

[0026] During the lifting process of the carriage 4, the support rod 301 pulls the pulley 302 to slide inside the slide groove 303, so that the tooth block 306 slides under the rack 304. When the carriage 4 stops lifting, the torsion spring will make the tooth block 306 engage with the rack 304, so that the support rod 301 supports the carriage 4 to prevent the carriage 4 from falling. When the carriage 4 needs to be lowered, the electromagnet 309 is energized so that the electromagnet 309 drives the tooth block 306 to overcome the elastic force of the torsion spring and move closer to the iron bar 308, so that the tooth block 306 cannot engage with the rack 304, thereby allowing the carriage 4 to descend. The carriage 4 can be stably lifted by multiple parallel hydraulic rods 2. When the carriage 4 tilts, the vibration motor 5 is driven to make the carriage 4 vibrate, so that the material inside the carriage 4 is emptied.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
