[0022] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 7 As shown, the present embodiment provides a dump truck which is convenient for unloading, comprising a dump truck frame 1, a middle jacking system 2, a left anchoring device 3, a right anchoring device 4, a rear anchoring device 5, a switch device 6 and a truck bed 7. Anchoring notches are arranged on the left anchoring device 3, the right anchoring device 4 and the rear anchoring device 5. The switch device 6 can be respectively engaged with the anchoring notches corresponding to the left anchoring device 3, the right anchoring device 4 and the rear anchoring device 5. The switch device 6 has a first state, a second state and a third state. When the switch device 6 is in the first state, it is only anchored with the left anchoring device 3. When the switch device 6 is in the second state, it is only anchored with the right anchoring device 4. When the switch device 6 is in the third state, it is only engaged with the rear anchoring device 5. In this way, the truck bed 7 can be deflected in three directions. The middle jacking system 2 is anchored at the bottom of the truck bed 7 to drive the truck bed 7 to flip. The switch device 6 is installed at the bottom of the truck bed 7 to control the locking and unlocking of each side of the truck bed 7.

[0023] Specifically, the dump truck frame 1 includes a frame body 11, a power wheel 12 and a universal wheel 13. Each power wheel 12 and the universal wheel 13 are installed at the bottom of the frame body 11. The universal wheel 13 can be installed on the frame body 11 horizontally. A control handle 111 is provided on the frame body 11. The control handle 111 drives the universal wheel 13 to rotate horizontally. The power wheel 12 drives the dump truck frame 1 to move, and the control handle 111 is used to control the steering of the frame body 11.

[0024] Specifically, the two power wheels 12 are respectively connected to the drive motor 14, a transmission shaft is installed between the two power wheels 12, the transmission shaft is connected to the output end of the drive motor 14 through a sprocket and a chain transmission, and the power wheels 12 are driven by the drive motor 14 to drive the frame body 11 to move.

[0025] Specifically, the middle jacking system 2 includes a jacking beam 21, two jacking sliders 22, a jacking motor 25, a jacking device 23 and two jacking connecting rods 24. The two jacking sliders 22 are slidably installed on the jacking beam 21 through a dovetail groove sliding pair. The output end of the jacking motor 25 is connected to the jacking slider 22 through a screw through a threaded pair. The two ends of the two jacking connecting rods 24 are respectively hinged on the jacking device 23 and the corresponding jacking slider 22. The jacking motor 25 drives the screw to rotate, which can drive the two jacking sliders 22 to move closer or farther from each other, thereby making the jacking device 23 rise and fall. It should be noted that the rotation direction of the screw and the two jacking sliders 22 is opposite, so that the movement directions of the two jacking sliders 22 are opposite when the screw rotates.

[0026] Specifically, the left anchoring device 3 includes a left anchoring rod 31 and a left universal bearing 32. The left anchoring rod 31 is installed on the left universal bearing 32. The left anchoring rod 31 is provided with an anchoring notch that cooperates with the switch device 6. When only the anchoring notch of the left anchoring rod 31 is anchored with the switch device 6, the truck bed 7 can only be flipped to the left side. At this time, the switch device 6 is in the first state.

[0027] Specifically, the right-side anchoring device 4 includes a right-side anchoring rod 41 and a right-side universal bearing 42. The right-side anchoring rod 41 is installed on the right-side universal bearing 42. The right-side anchoring rod 41 is provided with an anchoring notch that cooperates with the switch device 6. When only the anchoring notch of the right-side anchoring rod 41 is anchored with the switch device 6, the truck bed 7 can only be flipped to the right side. At this time, the switch device 6 is in the second state.

[0028] Specifically, the rear anchoring device 5 includes a rear anchoring rod 51 and a rear universal bearing 52. The rear anchoring rod 51 is installed on the rear universal bearing 52. The rear anchoring rod 51 is provided with an anchoring notch that cooperates with the switch device 6. When only the anchoring notch of the rear anchoring rod 51 is anchored with the switch device 6, the truck bed 7 can only be flipped to the rear side. At this time, the switch device 6 is in the third state.

[0029] Specifically, the switch device 6 includes a control pin 61, a switch control rod 62, a left control rod 63 and a right control rod 64. The control pin 61 is installed at the bottom of the truck bed 7. The switch control rod 62 is provided with a reference long hole 621, a plurality of third hook holes 622 and two transmission long holes 623. The directions of the two transmission long holes 623 and the reference long hole 621 are consistent with the length direction of the switch control rod 62. The direction of each third hook hole 622 is perpendicular to the length direction of the switch control rod 62. The width of each third hook hole 622 is wider than the diameter of the corresponding rear anchor rod 51, thereby avoiding interference between the third hook hole 622 and the rear anchor rod 51.

[0030] The switch control rod 62 is rotatably mounted on the control pin 61 through the third hook hole 622, and the left control rod 63 and the right control rod 64 are rotatably mounted on both ends of the switch control rod 62 through the corresponding transmission long holes 623, respectively. The left control rod 63 and the right control rod 64 are slidably mounted on the bottom of the bucket 7. The left control rod 63 and the right control rod 64 are both provided with a clamping notch 65 that matches the anchoring notch. The switch control rod 62 is rotated to push the left control rod 63 and the right control rod 64 to slide along the bottom of the bucket 7, so that the corresponding anchoring notch is clamped on the left The engaging notch 65 on the control rod 63 or the engaging notch 65 on the right control rod 64 is engaged, thereby controlling the switch device 6 to switch between the first state and the second state. When the switch device 6 needs to be in the third state, the switch control rod 62 is rotated so that the corresponding anchoring notch is disengaged from the engaging notch 65 on the left control rod 63 and the engaging notch 65 on the right control rod 64, and is pushed in the direction of the switch control rod 62 so that the third hook hole 622 engages with the anchoring notch on the rear anchor rod 51, thereby placing the switch device 6 in the third state.

[0031] like Figure 4 As shown, the sides of the top of the truck bed 7 are wrapped with steel bars 72, thereby forming an inward slope 71 on the top of the truck bed 7, which can prevent concrete from overflowing and enhance the strength of the truck bed 7 to increase the loading capacity.
