The planetary gear 105, the star gear rack 106, the intermediate gear 107, and the left side support 108 are all installed inside the transverse gear 103, and the purpose is to allow the transverse gear 103 to protect the internal device.

A plurality of second worm wheels 204 are also meshedly installed at both ends of the rope screw 203, and the second worm wheels 204 are rotatably connected to the main bracket 102. A lifting winch 205 is fixedly installed on the second worm wheel 204, and the lifting winch 205 is meshed with The main bracket 102 is rotatably connected, and a lifting steel cable 206 is fixedly installed on the lifting winch 205. A lifting tray 207 is fixedly installed on the end of the lifting steel cable 206 away from the main bracket 102, and a plurality of semicircular springs 302 are fixedly installed on the lifting tray 207. A semicircular frame 301 is fixedly installed on the other end of the semicircular spring 302. The semicircular frame 301 is movably connected to the lifting tray 207. A material box 307 is fixedly installed on the end of the semicircular frame 301 away from the lifting tray 207. A plurality of gate plates 306 are rotatably installed on the material box 307. A gate torsion spring is fixedly installed on the gate plate 306, and the other end of the gate torsion spring is fixedly installed on the material box 307.

[0025] like Figure 5 , Figure 6 As shown, a plurality of gate motors are fixedly mounted on the material box 307, a first gear 304 is fixedly mounted on the output shaft of the gate motor, a gate gear 303 is meshedly mounted on the first gear 304, the gate gear 303 is rotatably connected with the material box 307, a gate cable 305 is fixedly mounted on the gate gear 303, the other end of the gate cable 305 is fixedly mounted on the gate plate 306, the gate cable 305 on the gate plate 306 is mounted on the end away from the lifting tray 207, and the gate gear 303 is rotatably connected with the material box 307. 03 is also meshed with a counterweight gear 308, which is rotatably connected to the material box 307. The counterweight gear 308 is also meshed with a counterweight rack 309, which is slidably connected to the material box 307. A counterweight spring 310 is fixedly installed on the counterweight rack 309, and the other end of the counterweight spring 310 is fixedly installed on the material box 307 for reset. A counterweight block is provided at one end of the counterweight rack 309 away from the counterweight spring 310 to press the material box 307 to tilt.

[0026] Work away from: When the device is in use, the transverse rack 101 needs to be fixedly installed on the wall, and the lifting tray 207 is in a suspended state. To ensure that the lifting space of the lifting tray 207 is unobstructed, after the device is set up and needs to be worked, the active motor 115 can be started in the initial state, so that the active motor 115 drives the outer cylinder rod 111 and the intermediate gear 107 to rotate through the motor gear 114 and the passive gear 113. In the initial state, the outer clamping tooth 109 is engaged with the first clamping tooth rod 402 and is limited by the first clamping tooth rod 402. Therefore, the left side rod 110, the left side support 108, the star gear rack 106, and the right inner rod 112 cannot rotate at this time, and the rotation of the intermediate gear 107 at this time will drive the planetary gear 105 to rotate, and the planetary gear 105 will drive the transverse gear 103 to rotate around the axis of the right inner rod 112 through the locking gear ring 104, and the rotation of the transverse gear 103 will drive the device to slide on the transverse rack 101, and the lifting position of the device can be adjusted at this time, so that when loading and unloading materials, the device can be dumped or loaded at the specified position.

[0027] When the device is to lift materials, the switching motor can be started to drive the second engaging gear rod 403 and the first engaging gear rod 402 to move through the switching gear 401, so that the second engaging gear rod 403 is engaged with the positioning gear ring 104, thereby limiting the rotation of the positioning gear ring 104 and the transverse gear 103, and at the same time driving the first engaging gear rod 402 to disengage the first engaging gear rod 402 from the outer engaging gear 109, and then starting the active motor 115 to drive the outer cylinder rod 111 and the intermediate gear 107 to rotate, and at this time the positioning gear ring 104 is limited, while the galaxy gear rack 106 is not limited, so The planetary gear 105 will drive the galaxy gear frame 106 to rotate around the axis of the right inner rod 112 while rotating around itself. The rotation of the galaxy gear frame 106 will drive the left support 108, the left rod 110, and the right inner rod 112 to rotate together. At this time, the left rod 110 and the right inner rod 112 will drive the first worm 201 to rotate, allowing the first worm 201 to drive the rope screw 203 to rotate through the first worm gear 202, so that the rope screw 203 drives the lifting winch 205 through the second worm gear 204, and the lifting winch 205 can lift or lower the material box 307 and the material in the material box 307 by retracting or loosening the lifting cable 206.

[0028] When the material is to be dumped, after moving the device to the designated position, if the material needs to be dumped to any side of the material box 307 where the gate plate 306 is installed, the gate motor on the corresponding side can be started, and the gate motor drives the gate gear 303 to rotate, so that the gate gear 303 relaxes the gate cable 305, and the gate plate 306 is squeezed by the gate torsion spring and the material, so that the gate plate 306 is gradually opened, allowing the material to be dumped out of the material box 307. While the gate gear 303 is rotating, the gate gear 303 will also drive the counterweight gear 308 to rotate, and the counterweight gear 308 will drive the counterweight gear The counterweight rack 309 moves with the counterweight block on the counterweight rack 309 away from the center of the semicircular frame 301. The purpose is to allow the counterweight block on the counterweight rack 309 to move away from the center of the material box 307 while allowing the material box 307 to slide on the intermediate gear 107 with the semicircular frame 301, so that the material box 307 is tilted toward the side where the counterweight block moves, so that the material can be automatically dumped out of the material box 307. At this time, the semicircular spring 302 plays a resetting role. After the material in the material box 307 is dumped, the gate motor can be rotated in the opposite direction to restore the device to its initial state.
