[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0026] As Figures 1-3 shown, the present utility model provides a hand-pushed electric tipping truck, including a frame 1, and a hopper 2, a driving part and a transmission part arranged on the frame 1. The bottom plate 201 of the hopper 2 is inclined, and its lower end is connected to the frame 1 through a rotating assembly; an installation groove 101 is opened on the frame 1 for accommodating the driving part, the transmission part and the hopper 2; the driving part is in transmission connection with the hopper 2 through the transmission part, the driving part provides power for the hopper 2, and the transmission part is used to convert the linear motion of the driving part into the flipping motion of the hopper 2.

[0027] Further, the bottom plate 201 of the hopper 2 is gradually inclined downward from the rear end to the front end of the frame 1. The lower end of the bottom plate 201 is connected to the frame 1 through a rotating assembly, and the upper end of the bottom plate 201 is in transmission connection with the driving part through the transmission part. The four side plates of the hopper 2 are respectively inclined towards the bottom plate 201, so that the inner diameter of the accommodating cavity of the hopper 2 gradually decreases from top to bottom.

[0028] Compared with the flat bottom plate of the hopper in the prior art, the bottom plate 201 of the hopper 2 of the present utility model is inclined. During the flipping process, it is easier to reach a state close to vertical, so that the materials can be poured out more thoroughly, and the materials can also slide more smoothly along the bottom plate 201 and the side plates under the action of gravity, improving the unloading efficiency. Moreover, the driving part is in transmission connection with the hopper 2 through the transmission part, converting the linear motion into a flipping motion, realizing the automatic flipping of the hopper 2, reducing the labor intensity of the operator, and further improving the unloading efficiency.

[0029] As an optional implementation manner, the driving part includes an electric push rod 3 which is obliquely arranged; the transmission part includes a transmission assembly which is symmetrically arranged on both sides of the electric push rod 3; the transmission assembly includes a first transmission plate 4, a second transmission plate 5, a first connecting plate 6 and a second connecting plate 7; the second connecting plate 7, the first connecting plate 6, the second transmission plate 5 and the first transmission plate 4 are arranged in sequence along the direction close to the electric push rod 3, the telescopic end of the electric push rod 3 is rotationally connected to a position of the first transmission plate 4 close to the first end, the first end of the first transmission plate 4 is rotationally connected to the first end of the second transmission plate 5, and the second end of the second transmission plate 5 is rotationally connected to the inner wall of the installation groove 101. The second ends of two groups of second connecting plates 7, first connecting plates 6 and first transmission plates 4 are connected by a first rotating shaft 9 and correspond to the high end of the bottom plate 201 of the hopper 2. The first ends of the first connecting plate 6 and the second connecting plate 7 are connected by a second rotating shaft 10.

[0030] Further, the electric push rod 3 is obliquely arranged gradually upward from the rear end to the front end of the vehicle frame 1, and the telescopic end of the electric push rod 3 is rotationally connected to positions of two first transmission plates 4 close to the first end through a connecting shaft 12.

[0031] The transmission assembly is symmetrically arranged on both sides of the electric push rod 3 to balance the force condition of the hopper 2 during the flipping process.

[0032] As an optional implementation manner, the bottom plate 201 of the hopper 2 is connected to the second connecting plate 7 through a fixing frame 8. Through holes for the first rotating shaft 9 to pass through are formed in the side plates 801 of the fixing frame 8. The first connecting plate 6 is arranged on the bottom surface of the fixing frame 8 and is provided with a first card slot adapted to the first rotating shaft 9 and a second card slot adapted to the second rotating shaft 10.

[0033] Further, the bottom plate 201 of the hopper 2 is welded to the fixing frame 8, and the side plates 801 of the fixing frame 8 are bolted to the second connecting plate 7.

[0034] When the electric push rod 3 makes a telescopic movement, it pushes the two first transmission plates 4 to rotate around their rotational connection points with the second transmission plate 5. Since the second ends of the first transmission plates 4 are connected to the second connecting plate 7 and the first connecting plate 6 through the first rotating shaft 9, it drives the second connecting plate 7 and the first connecting plate 6 to rotate synchronously. And since the first transmission plate 4 is rotationally connected to the first end of the second transmission plate 5, it drives the second transmission plate 5 to swing. The second connecting plate 7 and the first connecting plate 6 are connected to the bottom plate 201 of the hopper 2 through the fixing frame 8. Therefore, the movement of the second connecting plate 7 and the first connecting plate 6 will drive the bottom plate 201 of the hopper 2 to flip around the axis of the rotating assembly until the required flipping angle is reached.

[0035] As an alternative implementation, the installation groove 101 is provided through the thickness direction of the vehicle frame 1, and a push rod mudguard 26 is provided corresponding to the position below the fixed end of the electric push rod 3 to protect the electric push rod 3 from being eroded by dirt and moisture.

[0036] As an alternative implementation, the rotating assembly includes a third rotating shaft 11 and a rotating plate 13. Both ends of the third rotating shaft 11 are rotatably connected to the vehicle frame 1; the number of rotating plates 13 is multiple, and they are sleeved on the third rotating shaft 11 and connected to the fixed frame 8.

[0037] Since the rotating plate 13 is rotatably matched with the third rotating shaft 11, the bottom plate 201 of the hopper 2 always rotates around the axis of the third rotating shaft 11 during the flipping process, improving the stability and accuracy of the flipping action.

[0038] As an alternative implementation, it further includes a front wheel assembly and a rear wheel assembly. The front wheel assembly includes a front wheel 14, a front wheel shaft 15, a motor 16 and an electromagnetic brake assembly 17.

The motor 16 is drivingly connected to the front wheel shaft 15, and the electromagnetic brake assembly 17 is provided on the motor 16; the rear wheel assembly includes a rear wheel 18, a rear wheel bracket 19 and a rear wheel main frame 20. The rear wheel main frame 20 is connected to the vehicle frame 1, and the rear wheel 18 is respectively connected to the two wing plates of the rear wheel main frame 20 through the rear wheel bracket 19.

[0039] The function of the front wheel assembly is to realize actions such as the vehicle moving forward, backward and turning.

[0040] The function of the rear wheel assembly is to follow the movement of the front wheels and support the weight of the rear part of the vehicle frame 1 to maintain the overall balance and stability.

[0041] It should be noted that the present utility model does not improve the transmission structure of the front wheel assembly and the rear wheel assembly. The existing technology is adopted and will not be elaborated here.

[0042] As an alternative implementation, the diameter of the rear wheel 18 is smaller than that of the front wheel 14, and the width of the rear wheel 18 is smaller than that of the front wheel 14, optimizing the weight distribution of the dump truck and making the dump truck more stable during movement.

[0043] As an alternative implementation, a motor mudguard 27 is provided on the vehicle frame 1 to cover the motor 16 and the electromagnetic brake assembly 17 to protect the motor 16 and the electromagnetic brake assembly 17 from being eroded by dirt and moisture.

[0044] As an alternative implementation, an operating platform 21 is provided at the rear end of the vehicle frame 1. A control switch and an electronic magnetic brake brushless controller 24 are provided on the operating platform 21; armrests 25 are provided on both sides of the operating platform 21 to provide a stable support for the operator.

[0045] Further, a rechargeable battery box is provided at the rear of the frame 1 for supplying electrical energy to the electric push rod 3, the motor 16, various electronic components on the operation table 21, etc.

[0046] The control switch includes a main switch 22 and an electric push rod switch 23. The main switch 22 is electrically connected to the rechargeable battery box and is used to control the power supply of the dump truck. Only when the main switch 22 is turned on can the electric push rod 3, the motor 16, various electronic components on the operation table 21, etc. obtain the electrical energy supply from the rechargeable battery box.

[0047] The electric push rod switch 23 is electrically connected to the electric push rod 3 and is used to control the telescopic movement of the electric push rod 3. By operating the electric push rod switch 23, the flipping and resetting of the bottom plate 201 of the hopper 2 are controlled to realize the loading and unloading of materials.

[0048] The electronic magnetic brake brushless controller 24 is electrically connected to the motor 16 and the electromagnetic brake assembly 17 and is used to start or stop the operation of the motor 16, control the rotation speed and direction of the motor 16, and start the electromagnetic brake assembly 17.
