The front end of the telescopic mechanism base is hinged with the vehicle body, and the first hydraulic cylinder is hinged between the rear end of the telescopic mechanism base and the vehicle body. Through the expansion and contraction of the first hydraulic cylinder, the telescopic mechanism base rotates around the front end, and the telescopic mechanism slide plate and the telescopic mechanism A second hydraulic cylinder is installed between the bases, and the sliding plate of the telescopic mechanism is pushed forward and backward on the telescopic mechanism base by the second hydraulic cylinder.

A controllable latch is provided on the front inner side of the large dumping bucket, and a rotatable one-way mechanism cover is provided on the top of the large dumping bucket. When the controllable latch is in the open state, it can restrict the outward rotation of the one-way mechanism cover. state, the one-way mechanism cover can be turned outward.

The top of the large tipping bucket is fixed with a large tipping bucket cover plate and is provided with an inlet and outlet, and the one-way mechanism cover plate is hinged with the large tipping bucket cover plate.

The automatic loading and unloading dump truck of the invention can realize automatic loading and unloading operations, reduces manpower operations, and improves work efficiency.

detailed description

Below in conjunction with Fig. 1 and Fig. 2, the automatic loading and unloading dump truck of the present invention will be further described.

The automatic loading and unloading dump truck of the present invention comprises a car body 1 and a large dumping bucket 12. The bottom of the big dumping bucket 12 is provided with a fixedly connected telescopic mechanism slide plate 9, and the telescopic mechanism slide plate 9 is installed on the telescopic mechanism base 6 in a sliding fit mode. The fixed support pad 5 is used to carry the telescopic mechanism base 6. The front end of the telescopic mechanism base 6 is fixedly connected to the rotary support 11. The rotary support 11 and the car body 1 form a hinge through the first hinge hole 10. The telescopic mechanism base 6 The rear end is fixedly connected to the first support 3, the first support 3 is hinged with the telescopic rod of the first hydraulic cylinder 2, the base of the first hydraulic cylinder 2 is hinged with the vehicle body 1, and telescopic movement is realized through the telescopic movement of the first hydraulic cylinder 2 Mechanism base 6 rotates around the front end. The both sides of telescoping mechanism slide plate 9 are fixed with the 3rd bearing 8, and the telescoping link of the 3rd bearing 8 and the 2nd hydraulic cylinder 7 is hinged, and the base of the 2nd hydraulic cylinder 7 is fixed on the 2nd telescoping mechanism base 6. The support 4 forms a hinge, and the large dump bucket 12 and the telescopic mechanism slide plate 9 move back and forth on the telescopic mechanism base 6 through the telescopic movement of the second hydraulic cylinder 7 .

In the present invention, a controllable latch 14 is provided on the front inner side of the large dumping bucket 12, and a rotatable one-way mechanism cover plate 13 is provided on the top of the large dumping bucket 12, and the one-way mechanism cover plate 13 is vertically downward under the action of gravity. When the controllable latch is in the open state, it can restrict the outward rotation of the one-way mechanism cover plate 13, and in the closed state, the one-way mechanism cover plate 13 can rotate outward.

In the present invention, a large tipping bucket cover plate 16 is fixed on the top of the big tipping bucket 12 and is provided with an inlet and outlet. The two hinge holes 15 form a hinge, and the one-way mechanism cover plate 13 can also directly form a hinge with the vehicle body 1 .

The working principle of the present invention is as follows:

1. When automatic shoveling operation is required, the telescopic mechanism base 6 is controlled to rotate around the first reaming hole 10 through the elongation movement of the first hydraulic cylinder 2, and then drives the telescopic mechanism slide plate 9 and the large tipping bucket 12 installed on the telescopic mechanism base 6 Rotate, now the controllable latch 14 is in an open state, when rotated to a suitable position, through the elongation motion of the second hydraulic cylinder 7, the telescopic mechanism slide plate 9 is pushed to drive the large dump bucket 12 to stretch out along the telescopic mechanism base 6, and stretch out to When in a suitable position (i.e., the shoveling action can be realized), the car body 1 continues to move forward, and the one-way mechanism cover plate 13 can only rotate inward due to the rotation of the one-way mechanism cover plate 13 and is supported by the controllable latch 14 , can not rotate outwards, so that the material can be smoothly loaded into the large dump bucket 12 from the inlet and outlet, and the shoveling operation is completed.

2. When a shovel is completed, the first hydraulic cylinder 2 and the second hydraulic cylinder 7 cooperate to contract, so that the large dump bucket 12 returns to the horizontal position, and the goods move to the rear of the large dump bucket 12 .

3. Repeat the above actions until the large tipping bucket 12 is filled with enough goods, and the loading is completed.

4. When unloading, close the controllable latch 14, and the one-way mechanism cover plate 13 can rotate freely. Through the elongation movement of the first hydraulic cylinder 2, the large dumping bucket 12 is driven to rotate around the first hinge hole 10, and rotate to When the angle is suitable, the one-way mechanism cover plate 13 rotates outwards, and the material can be smoothly poured out from the inlet and outlet to complete the discharge.
