DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1, as Figure 1-4 , Figure 7 As shown, an electric transport vehicle with an automatic unloading structure includes a transport vehicle 1. The transport vehicle 1 is a prior art and can transport large tonnage of goods. An outer shell 2 is provided on the rear side of the transport vehicle 1, and a transport component 3 is provided at the lower end of the outer shell 2. Two intermittent components 4 are symmetrically provided on the left and right sides of the transport component 3, so that the transport component 6 can maintain intermittent movement. The upper ends of the four intermittent components 4 are all provided with connecting components 5, so that the transport component 3 can be connected with the transport component 2 6. While the steel plates at the bottom are being unloaded, the steel plates at the upper part also fall down one by one, and the steel plates can be continuously pushed out of the stack, realizing an efficient unloading process. The inner cavity of the outer shell 2 is provided with four transport components 2 6, ensuring that a certain distance is maintained between the steel plates, which is conducive to air circulation, reduces friction and wear between the steel plates, and achieves the effect of downward transmission.

[0020] During the operation of this embodiment, through the coordination between various structures, automatic unloading is achieved while maintaining a certain distance between the steel plates, avoiding damage caused by collision and extrusion during the movement, ensuring continuous and uninterrupted unloading, improving the overall unloading efficiency, and reducing the labor of manual movement of steel plates.

[0021] Embodiment 2: Based on Embodiment 1, this embodiment is for achieving the effect of unloading steel plates stably and uninterruptedly.

[0022] For details, see Figure 1-10 The outer shell 2 includes a base 21 fixedly connected to both sides of the upper rear end of the transport vehicle 1, and the upper ends of the two bases 21 are fixedly connected to a cargo box 22, which can provide protection for the internal steel plate, and the lower end of the cargo box 22 is fixedly connected to a base 23.

[0023] The rear side of the cargo box 22 is rotatably connected to a rotating shaft 24, and the outer surface of the rotating shaft 24 is fixedly connected to a flip door 25, which can be opened to unload the goods. The lower end of the cargo box 22 is provided with two through slots 26.

[0024] For further information, see Figure 6-9The transport component 3 includes a bidirectional shaft motor 31 fixedly connected to the upper end of the base 23, and the output ends on both sides of the bidirectional shaft motor 31 are fixedly connected to sprockets 32. The two sprockets 32 have the same rotation direction and rotate counterclockwise, so that the chain conveyor belt 33 also moves counterclockwise to transport the steel plate outward. The outer surfaces of the two sprockets 32 are meshed and connected with the chain conveyor belt 33. The output ends on both sides of the sprockets 32 extend to the inner surfaces of the two bases 21. The upper surface of the chain conveyor belt 33 is fixedly connected to a fixed seat 34, and the upper end of the fixed seat 34 is fixedly connected to a pushing seat 35. The pushing seat 35 moves with the chain conveyor belt 33, and can push the bottom steel plate outward.

[0025] The sprocket 32 ​​and the chain conveyor belt 33 mentioned above are prior art and are only briefly described in this scheme. They are mainly used to connect the driving device and the load-bearing component, transmit power and carry materials, have the characteristics of high strength, high wear resistance and corrosion resistance, and can operate stably for a long time in harsh environments.

[0026] Its main working principles are: Starting stage: when the bidirectional shaft motor 31 is started, the sprocket wheel 32 is driven to rotate, and the sprocket wheel 32 is engaged with the chain conveyor belt 33, driving the chain conveyor belt 33 to start circulating motion. There are generally two sprocket wheels 32, which are located at the front and rear ends of the chain conveyor belt 33.

[0027] Conveying stage: the material is placed on a load-bearing member such as a pallet or a conveyor belt. As the chain conveyor belt 33 circulates, the load-bearing member carries the material and moves along a predetermined path.

[0028] Stable conveying: During the conveying process, the guide rail and the tensioning device ensure that the chain conveyor belt maintains stability and proper tension to prevent it from derailing or loosening. The guide device ensures that the material maintains the correct direction during the conveying process.

[0029] Stopping stage: when it is necessary to stop conveying, the bidirectional shaft motor 31 stops running, the sprocket 32 ​​stops rotating, and the chain conveyor belt 33 also stops moving. At this time, the material on the bearing member also stops moving.

[0030] For further information, see Figure 7-9 The intermittent assembly 4 includes a transmission body 41 fixedly connected to one end of the sprocket 32, the inner surface of the transmission body 41 is rotatably connected to a rotating shaft 42, and the end of the rotating shaft 42 away from the transmission body 41 is fixedly connected to a half gear 45.

[0031] The transmission body 41 mentioned above is a prior art, and its main function is to adjust the transmission ratio. By adjusting the transmission ratio, the transmission can expand the variation range of the torque and speed of the driving wheel to adapt to different driving conditions.

[0032] The transmission body 41 is mainly composed of a torque converter, planetary gears and a hydraulic control system. The torque converter is the core component of the automatic transmission and is composed of components such as a pump wheel, a turbine wheel and a guide wheel.

[0033] Working principle: The torque converter achieves the purpose of speed and torque change through hydraulic transmission and gear combination. When the engine power is input to the pump wheel, the pump wheel drives the turbine to rotate through the liquid, and then a guide wheel is added between the pump wheel and the turbine to improve the transmission efficiency of the liquid. Since the automatic speed and torque change range of the torque converter is not large enough and the efficiency is low, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system will automatically manipulate the planetary gears as the engine works, thereby realizing automatic gear shifting.

[0034] Therefore, when the sprocket 32 ​​drives the chain conveyor belt 33 to complete a circle, the rotating shaft 42 can rotate a circle, and due to the gear mechanism inside the speed changer body 41, the rotation direction can be changed, so that the rotating shaft 42 drives the half gear 45 to rotate in the clockwise direction.

[0035] The outer surface of the half gear 45 is meshed with the cylindrical gear 46, and the half gear 45 and the cylindrical gear 46 realize intermittent rotation. When the pushing seat 35 transports the steel plate, the half gear 45 rotates slowly and is in a non-meshing state with the cylindrical gear 46. When the pushing seat 35 moves to the bend together with the chain conveyor belt 33 and pushes the steel plate away completely, when it returns downward, the half gear 45 and the cylindrical gear 46 begin to mesh. The diameter ratio of the half gear 45 and the cylindrical gear 46 is two to one. When the tooth surface of the half gear 45 meshes with the cylindrical gear 46, the cylindrical gear 46 can rotate one full circle counterclockwise.

[0036] For further information, see Figure 9-10 The connecting component 5 includes a limiting rod 51 fixedly connected to the inner surface of the cylindrical gear 46, one end of the limiting rod 51 is fixedly connected to a bevel gear 1 52, and the end of the bevel gear 1 52 away from the limiting rod 51 is rotatably connected to the base 1 21. The limiting rod 51 can provide limiting for the cylindrical gear 46 and the bevel gear 1 52. The outer surface of the bevel gear 1 52 is meshedly connected with a bevel gear 2 53, so that the bevel gear 2 53 rotates clockwise. The upper end of the bevel gear 2 53 is fixedly connected to a rotating shaft 2 54, and the outer surface of the rotating shaft 2 54 is rotatably connected to the base 1 21.

[0037] For further information, see Figure 8 and Fig. 9The upper end of the rotating shaft 2 54 is fixedly connected with a bevel gear 3 55, and the outer surface of the bevel gear 3 55 is meshedly connected with a bevel gear 4 56, so that the bevel gear 4 56 moves counterclockwise, and the front side of the bevel gear 4 56 is fixedly connected with the rotating shaft 3 57, and the upper end of the base 1 21 is fixedly connected with four protective shells 571, which can protect the structure of the connecting component 5 exposed to the outside.

[0038] For further information, see Fig. 9 and Fig.10 The transport component 2 6 includes a support seat 61 fixedly connected to the upper end of the base 1 21. The end of the rotating shaft 3 57 away from the bevel gear 4 56 passes through the support seat 61 and is fixedly connected to the sprocket 2 62. The rotating shaft 3 57 can drive the sprocket 2 62 to rotate counterclockwise, so that the chain conveyor belt 2 63 runs counterclockwise as a whole. On average, the limit seat 64 drops one grid per rotation to prepare for the unloading of the next steel plate.

[0039] For further information, see Fig.10 The outer surface of the sprocket wheel 62 is meshedly connected with the chain conveyor belt 63, and the outer surface of the chain conveyor belt 63 is fixedly connected with a plurality of limit seats 64. The steel plates can be stored on the limit seats 64, which can maintain the distance between the steel plates and facilitate the subsequent unloading operation.

[0040] A plurality of steel plates are respectively placed between the limit seats 64 for storage, and the lowest steel plate is directly placed on the bottom wall of the cargo box 22. When unloading is required, the bidirectional shaft motor 31 is started to make the sprockets 32 on both sides rotate counterclockwise, so that the chain conveyor belt 33 also moves counterclockwise, so that the pushing seat 35 is against the front end of the steel plate, and the steel plate at the bottom is transported outward together with the chain conveyor belt 33. When the pushing seat 35 transports the steel plate, the rotating shaft 42 is changed in speed through the speed changer body 41. When the sprocket 32 ​​drives the chain conveyor belt 33 to complete a circle, the rotating shaft 42 rotates a full circle, and due to the gear mechanism inside the speed changer body 41, the rotation direction can be changed, so that the rotating shaft 42 drives the half gear 45 to rotate in the clockwise direction.

[0041] When the pushing seat 35 moves to the turning point with the chain conveyor belt 1 33 and pushes the steel plate away completely, the half gear 45 begins to mesh with the cylindrical gear 46. When the tooth surface of the half gear 45 meshes with the cylindrical gear 46, the cylindrical gear 46 can rotate one full circle counterclockwise, driving the limiting rod 51 and the bevel gear 1 52 to rotate counterclockwise, so that the bevel gear 2 53, the rotating shaft 2 54 and the bevel gear 3 55 rotate clockwise, so that the bevel gear 4 56 and the rotating shaft 3 57 drive the sprocket 2 62 and the chain conveyor belt 2 63 to rotate counterclockwise, and move the limiting seat 64 downward by one grid, so that the steel plate located on the lowermost limiting seat 64 falls to the bottom wall of the cargo box 22, and then the next round of outward transportation of the pushing seat 35 is carried out.

[0042] Therefore, this solution uses two components, namely, transport component 1 3 and transport component 2 6, to respectively realize the outward unloading and downward movement of the steel plates, and uses the intermittent component 4 and the connecting component 5 to realize the connection and conversion between the two, so that after each transport component 1 3 unloads a steel plate, the transport component 2 6 will cause another steel plate to fall on the bottom wall of the cargo box 22, thereby realizing the continuous unloading of the steel plates while maintaining the spacing between the steel plates, reducing the waiting time and improving the overall unloading efficiency.

[0043] It should be noted that the specific installation method, circuit connection method and control method of the bidirectional shaft motor 31, chain conveyor belt 33 and speed changer body 41 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
