[0002] A semi-trailer is a trailer with the axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, which are divided into many types such as 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, low-bed semi-trailers, etc. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a traction pin, and the semi-trailer needs to use an automatic unloading platform when unloading.

[0003] However, the prior art still has the following problems:

[0004] First, most of the existing semi-trailer unloading platforms are not convenient for adjusting the height and angle, which causes many inconveniences when unloading. Different semi-trailers have different cargo box heights. If the platform cannot adjust the height and angle, it can only be applied to a semi-trailer of a single specification, which has limitations.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: Figure 1-3As shown, the utility model provides an automatic unloading platform for a semi-trailer, including a bottom plate 1, a unloading plate 2 is arranged above the bottom plate 1, two first telescopic rods 3 are fixedly arranged on one side of the upper end of the bottom plate 1, the upper ends of the two first telescopic rods 3 are fixedly arranged on a first support plate 31, the upper end of the first support plate 31 is rotatably connected to the unloading plate 2, two second telescopic rods 32 are fixedly arranged on the upper end of the bottom plate 1, the upper ends of the two second telescopic rods 32 are fixedly arranged on a second support plate 33, the two first telescopic rods 3 are located on one side of the upper end of the bottom plate 1, and the two second telescopic rods 32 are fixedly arranged on one side of the upper end of the bottom plate 1. The telescopic rod 32 is located at the middle of the upper end of the bottom plate 1, and the upper end of the second support plate 33 is rotatably provided with two connecting pieces 66, and the upper end of the connecting piece 66 is fixedly provided with a T-shaped block 67. Both sides of the lower end of the discharge plate 2 are provided with T-shaped slots 68 for matching the T-shaped block 67, and the size of the T-shaped slot 68 is larger than the T-shaped block 67. The second support plate 33 and one end of the first support plate 31 are both rotatably provided with a rotating piece 61, and one end of the rotating piece 61 is fixedly provided with a screw 62, and the outer surface of the screw 62 is sleeved with a screw sleeve 6, and the upper end of the screw sleeve 6 is provided with a screw 62 for matching the screw 62. The screw sleeve 6 is provided with a screw thread groove, and a knob 64 is fixedly sleeved on the upper side of the outer surface of the screw sleeve 6. The lower end of the screw sleeve 6 is rotatably provided with a support member 65, and the support member 65 is rotatably connected to the bottom plate 1. The bottom plate 1 is used as a supporting and connected carrier plate. The material is unloaded through the unloading plate 2. The lower end side of the unloading plate 2 can adjust the height through the first support plate 31 and the first telescopic rod 3, and the lower end middle part of the unloading plate 2 can adjust the height through the second support plate 33 and the second telescopic rod 32. The specific steps of adjustment are: rotating the knob 64 so that the screw sleeve 6 is on the support member 65. When the screw 62 is rotated upward, the screw 62 extends upward with the rotation of the screw sleeve 6, thereby driving the rotating member 61 to rotate on the support plate, so that the height of the support plate changes. When the height of the second support plate 33 changes, the angle of the unloading plate 2 changes. At this time, the T-shaped block 67 on the connecting member 66 moves in the T-shaped groove 68. The structural design is reasonable and the adjustment is convenient. The height and inclination angle of the unloading plate 2 can be freely adjusted, so that the materials of the semi-trailer are convenient to unload. The height and inclination degree are adjustable, which can be matched with semi-trailers of different specifications and has high versatility.

[0021] Four brake wheels 11 are fixedly provided at the lower end of the base plate 1, and the four brake wheels 11 are distributed in a rectangular array, and the brake wheels 11 make the platform easy to move.

[0022] Both ends of the unloading plate 2 are connected with mounting strips 5 by bolts, and a guardrail 51 is fixedly provided on the upper end of the mounting strip 5. The guardrail 51 can be installed through the detachable mounting strip 5 to improve the safety of unloading.

[0023] Embodiment 2: Figure 4As shown, an indirect plate 4 is provided on one side of the upper end of the unloading plate 2, two clamping blocks 41 are fixedly provided on one side of the upper end of the indirect plate 4, a mounting plate 42 is fixedly provided on one end of the indirect plate 4, two plugging columns 43 are fixedly provided on the lower end of the mounting plate 42, and two column grooves 44 for cooperating with the plugging columns 43 are provided on one side of the upper end of the unloading plate 2. The indirect plate 4 is clamped in the unloading position of the semi-trailer by the clamping blocks 41, and the indirect plate 4 is installed by inserting the plugging columns 43 at the lower end of the mounting plate 42 into the column grooves 44. The indirect plate 4 is easy to install and can be easily installed. As an indirect channel between materials and the platform, it can assist in the unloading work of materials and further improve the use effect of the unloading platform.

[0024] The end of the unloading plate 2 away from the indirect plate 4 is inclined, and the angle between the inclined surface and the unloading plate 2 is fifteen degrees. The inclined surface treatment makes it easier for materials to fall.

[0025] Working principle: the bottom plate 1 is used as a supporting and connected carrier plate, and the material is discharged through the discharge plate 2. The lower end side of the discharge plate 2 can adjust the height through the first support plate 31 and the first telescopic rod 3, and the lower middle part of the discharge plate 2 can adjust the height through the second support plate 33 and the second telescopic rod 32. The specific adjustment steps are: turn the knob 64 to make the screw sleeve 6 rotate on the support member 65. At this time, the screw rod 62 extends upward with the rotation of the screw sleeve 6, thereby driving the rotating member 61 to rotate on the support plate, so that the height of the support plate changes. When the height of the second support plate 33 changes, the angle of the discharge plate 2 changes. At this time, the T-shaped block 67 on the connecting member 66 moves in the T-shaped groove 68. The structural design is reasonable and the adjustment is convenient. The height and tilt angle of the discharge plate 2 can be freely adjusted, so that the materials of the semi-trailer are convenient to unload. The height and tilt degree are adjustable, which can be matched with semi-trailers of different specifications, and has high versatility.

[0026] The brake wheel 11 makes the platform easy to move;

[0027] A guardrail 51 can be installed via the detachable mounting strip 5 to improve the safety of unloading;

[0028] The indirect plate 4 is clamped at the unloading position of the semi-trailer by the clamping block 41, and the indirect plate 4 is installed by inserting the plug column 43 at the lower end of the mounting plate 42 into the column groove 44. The indirect plate 4 is easy to install and can be easily installed as an indirect channel between the material and the platform, which can assist in the unloading of materials and further improve the use effect of the unloading platform.
